Description

Technical Field

[0001] This application relates to the field of processing technology for raw materials with multiple slag and aggregate, and in particular to a continuous processing system for processing raw materials with multiple slag and aggregate. Background Technology

[0002] Multi-residue and multi-bone raw materials refer to raw materials containing a large amount of hard bone, soft tissue residue, and fascia. Common examples include frozen fish heads, livestock and poultry skeletons, and aquatic by-products. These raw materials are rich in nutrients such as protein and calcium, and have significant utilization value in the food, feed, and biological product industries. In existing technologies, continuous processing systems for handling multi-residue and multi-bone raw materials are typically production lines composed of sequentially combined functional units such as crushing, grinding, and conveying. Through continuous flow, the raw materials are processed and transformed from their initial form into the target product.

[0003] However, existing continuous processing systems for handling raw materials with multiple slag and aggregate content suffer from poor product particle size consistency and insufficient system stability in practical applications, making it difficult to meet the subsequent production requirements for product quality and continuous, efficient system operation. Summary of the Invention

[0004] This application provides a continuous processing system for processing raw materials with multiple slag and aggregate components, which can improve the technical problems of poor product particle size consistency and insufficient system operation stability in related technologies under practical application scenarios.

[0005] In a first aspect, embodiments of this application provide a continuous processing system for handling raw materials with multiple slag and aggregate components, comprising a pretreatment module, a thermo-rheology synergistic module, a two-stage wet grinding closed-loop module, an online detection and control module, and a sanitary cleaning unit connected in sequence; wherein: The pretreatment module includes a coarse crushing unit and a fine crushing unit arranged sequentially for progressively crushing multi-slag and multi-bone raw materials; The thermo-rheology co-processing module includes a thermal slowing unit for heating and softening multi-slag and multi-bone raw materials after stepwise crushing, a rheology and solid content detection unit for real-time acquisition of rheological properties and solid content data of the heated and softened multi-slag and multi-bone raw materials, and an intelligent limited water addition unit for adding a limited amount of water to the heated and softened multi-slag and multi-bone raw materials based on feedback control of the rheological properties and solid content data. The two-stage wet grinding closed-loop module includes a primary wet grinding unit for preliminary wet grinding of the polyslag and polybone raw material processed by the thermo-rheology collaborative module, a secondary wet grinding unit for fine wet grinding of the polyslag and polybone raw material after preliminary wet grinding, and a closed-loop reflux unit for returning the polyslag and polybone raw material that does not meet the preset particle size requirement after fine wet grinding to the secondary wet grinding unit for fine wet grinding again. The online detection and control module includes an online particle size detection unit for detecting the particle size of the multi-slag and multi-bone raw material after fine wet milling, and a control unit for adjusting the heating state of the thermal retardation unit, the water addition amount of the intelligent limited water addition unit, the operating parameters of the secondary wet milling unit, and the reflux state of the closed-loop reflux unit based on the detection results of the online particle size detection unit and the data collected by the rheology and solids content detection unit. The hygienic cleaning unit is used to clean the internal pipelines and functional units of the continuous processing system.

[0006] The technical solutions described in this application embodiment have at least the following technical effects: The continuous processing system for processing multi-slag and multi-aggregate raw materials provided in this application includes a pretreatment module, a thermo-rheology co-processing module, a two-stage wet grinding closed-loop module, an online detection and control module, and a hygienic cleaning unit connected in sequence. The pretreatment module includes a coarse crushing unit and a fine crushing unit arranged in sequence for progressively crushing the multi-slag and multi-aggregate raw materials, which ensures the initial morphology of the raw materials is uniform, laying the foundation for subsequent continuous processing. The thermo-rheology co-processing module includes a thermal softening unit for heating and softening the progressively crushed multi-slag and multi-aggregate raw materials, and a flow rate monitoring unit for real-time acquisition of the flow rate of the heated and softened multi-slag and multi-aggregate raw materials. The system includes a rheology and solids content detection unit for varying properties and solids content data, and an intelligent limited water addition unit for adjusting the amount of water added to the heated and softened multi-slag and multi-aggregate raw material based on feedback from the rheology and solids content data. The thermal retardation unit reduces the hardness and brittleness threshold of the multi-slag and multi-aggregate raw material, facilitating subsequent grinding. The rheology and solids content detection unit provides real-time data support for processing parameter control, and the intelligent limited water addition unit precisely maintains the pumpability of the raw material, reducing subsequent energy consumption increases due to ineffective water addition. The two-stage wet grinding closed-loop module includes a process for the multi-slag and multi-aggregate raw material treated by the thermo-rheology co-processing module. The system comprises a primary wet grinding unit for initial wet grinding, a secondary wet grinding unit for fine wet grinding of the multi-slag and multi-aggregate raw material after initial wet grinding, and a closed-loop reflux unit for returning the multi-slag and multi-aggregate raw material that does not meet the preset particle size requirements after fine wet grinding to the secondary wet grinding unit for further fine wet grinding. The primary wet grinding unit can initially remove coarse aggregate peaks, the secondary wet grinding unit can further refine the raw material particle size, and the closed-loop reflux unit can ensure that the product particle size is uniform and meets the standards, reducing coarse aggregate residue. The online detection and control module includes an online particle size detection unit for detecting the particle size of the multi-slag and multi-aggregate raw material after fine wet grinding, and a unit for determining the particle size based on the online particle size detection... The system utilizes the detection results from the measurement unit and the data collected from the rheology and solids content detection unit to control the heating state of the thermal retardation unit, the water addition amount of the intelligent limited water addition unit, the operating parameters of the secondary wet grinding unit, and the reflux state of the closed-loop reflux unit. The online particle size detection unit can monitor the product particle size in real time, and the control unit can achieve coordinated and linked control of all process parameters to ensure stable and controllable processing. The hygienic cleaning unit is used to clean the internal pipelines and functional units of the continuous processing system, reducing equipment blockage, contamination, and malfunctions caused by raw material residues, ensuring the system's hygienic compliance and continuous, efficient operation. This continuous processing system for handling multi-slag and multi-aggregate raw materials effectively solves the problems of poor product particle size consistency and insufficient system stability in existing technologies, achieving efficient, stable, and high-quality continuous processing of multi-slag and multi-aggregate raw materials.

[0007] Secondly, embodiments of this application provide a continuous processing method for processing multi-slag and multi-aggregate raw materials, applied to the continuous processing system for processing multi-slag and multi-aggregate raw materials described in any of the first aspects above, the method comprising: The coarse crushing unit and fine crushing unit of the pretreatment module are used to crush the multi-slag and multi-aggregate raw material step by step to obtain the crushed multi-slag and multi-aggregate raw material. The crushed multi-slag and multi-bone raw material is heated and softened by the thermal moderating unit of the thermal-rheology synergistic module to obtain the heated and softened multi-slag and multi-bone raw material. At the same time, the rheology and solid content detection unit of the thermal-rheology synergistic module collects the rheological characteristics and solid content data of the heated and softened multi-slag and multi-bone raw material in real time. Then, the intelligent limited water addition unit of the thermal-rheology synergistic module adds a limited amount of water to the heated and softened multi-slag and multi-bone raw material based on the rheological characteristics and solid content data to obtain multi-slag and multi-bone raw material with added water. The polystyrene and polybone raw material with added water is initially wet-milled by the first-stage wet-milling unit of the two-stage wet-milling closed-loop module to obtain the initially wet-milled polystyrene and polybone raw material. Then, the polystyrene and polybone raw material is finely wet-milled by the second-stage wet-milling unit of the two-stage wet-milling closed-loop module to obtain the finely wet-milled polystyrene and polybone raw material. The particle size of the finely wet-milled polyslag and polyabrasive raw material is detected by the online particle size detection unit of the online detection and control module. If the finely wet-milled polyslag and polyabrasive raw material does not meet the preset particle size requirement, the finely wet-milled polyslag and polyabrasive raw material that does not meet the preset particle size requirement is mixed with the heated and softened polyslag and polyabrasive raw material through the closed-loop reflux unit of the two-stage wet milling closed-loop module to obtain the mixed polyslag and polyabrasive raw material. The mixed polyslag and polyabrasive raw material is then refluxed to the secondary wet milling unit for fine wet milling again. The control unit of the online detection and control module, in conjunction with the detection results of the online particle size detection unit and the rheological properties and solid content data, regulates the heating state of the thermal retardation unit, the water addition amount of the intelligent limited water addition unit, the operating parameters of the secondary wet grinding unit, and the reflux state of the closed-loop reflux unit.

[0017] Multi-residue and multi-bone raw materials refer to raw materials containing a large amount of hard bone, soft tissue residue, and fascia. Common examples include frozen fish heads, livestock and poultry skeletons, and aquatic by-products. These raw materials are rich in nutrients such as protein and calcium, and have significant utilization value in the food, feed, and biological product industries. In existing technologies, continuous processing systems for handling multi-residue and multi-bone raw materials are typically production lines composed of sequentially combined functional units such as crushing, grinding, and conveying. Through continuous flow, the raw materials are processed and transformed from their initial form into the target product.

[0018] The continuous processing system for handling raw materials with multiple slags and aggregates in related technologies suffers from poor product particle size consistency and insufficient system stability in practical applications, making it difficult to meet the subsequent production requirements for product quality and continuous and efficient system operation.

[0019] Based on this, in order to improve the problems of poor product particle size consistency and insufficient system operation stability in the continuous processing system for processing raw materials with multiple slags and aggregates in the relevant technology under actual application scenarios, the embodiments of this application provide the following solutions.

[0020] Please see Figure 1 This application provides a continuous processing system for processing raw materials with multiple slag and aggregate components. The continuous processing system includes a pretreatment module, a thermo-rheology synergistic module, a two-stage wet grinding closed-loop module, an online detection and control module, and a hygienic cleaning unit, connected sequentially. Wherein: The pretreatment module includes a coarse crushing unit and a fine crushing unit arranged sequentially for the step-by-step crushing of raw materials with multiple slag and aggregates; The thermo-rheology co-processing module includes a thermal slowing unit for heating and softening multi-slag and multi-bone raw materials after stepwise crushing, a rheology and solids detection unit for real-time acquisition of rheological properties and solids content data of the heated and softened multi-slag and multi-bone raw materials, and an intelligent limited water addition unit for adding a limited amount of water to the heated and softened multi-slag and multi-bone raw materials based on feedback control of rheological properties and solids content data. The two-stage wet grinding closed-loop module includes a primary wet grinding unit for preliminary wet grinding of the polyslag and polyaggregate raw material after the thermo-rheology collaborative module, a secondary wet grinding unit for fine wet grinding of the polyslag and polyaggregate raw material after preliminary wet grinding, and a closed-loop reflux unit for returning the polyslag and polyaggregate raw material that does not meet the preset particle size requirements after fine wet grinding to the secondary wet grinding unit for fine wet grinding again. The online detection and control module includes an online particle size detection unit for detecting the particle size of the multi-slag and multi-bone raw material after fine wet milling, and a control unit for adjusting the heating state of the thermal retardation unit, the water addition amount of the intelligent limited water addition unit, the operating parameters of the secondary wet milling unit, and the reflux state of the closed-loop reflux unit based on the detection results of the online particle size detection unit and the data collected by the rheology and solids content detection unit. The hygienic cleaning unit is used to clean the internal pipelines and functional units of a continuous processing system.

[0021] It is understandable that a continuous processing system for handling multi-residue and multi-bone raw materials refers to a combination of automated processing equipment that enables uninterrupted processing from raw material pretreatment to finished product processing of mixed raw materials containing solid residues and bone components. The goal is to process multi-residue and multi-bone raw materials into products with uniform particle size (such as bone paste, meat and bone paste, etc.). Multi-residue and multi-bone raw materials are the processing targets of continuous processing systems for handling multi-residue and multi-bone raw materials. Specifically, they refer to mixed raw materials containing meat residues, bone fragments, and a small amount of connective tissue, such as chicken bones and pork bones and meat scraps left over from food processing plants, slaughterhouse offal, and fish bones and fish meat scraps left over from aquatic product processing. They are characterized by uneven solid particle hardness and poor flowability, and direct processing can easily lead to equipment blockage or uneven product particle size. Sequential connection refers to the fixed connection of each module through food-grade stainless steel pipelines in the order of the processing flow: pretreatment module, thermo-rheology synergistic module, and two-stage wet grinding closed-loop module. The inner wall of the pipeline is smooth and without dead corners. Raw materials with a lot of slag and bone can flow continuously through each module under the drive of gravity or conveying equipment without process interruption, backflow or raw material retention, thus improving the continuity of processing.

[0022] The pretreatment module is designed to progressively crush lumpy, high-quality raw materials into smaller particles suitable for subsequent heating, softening, and wet grinding. The pretreatment module comprises a coarse crushing unit and a fine crushing unit connected in series. The coarse crushing unit breaks down large, high-quality raw materials into medium-sized particles; examples include meat grinders, jaw crushers, and blade crushers. The fine crushing unit further refines these medium-sized particles into smaller ones; examples include meat grinders, toothed roller crushers, and colloidal fine crushers. The coarse and fine crushing units are connected by short pipelines. During operation, the high-quality raw materials are first fed into the coarse crushing unit, where they undergo initial crushing to form larger coarse particles. These coarse particles then automatically flow into the fine crushing unit, where they undergo secondary refinement to form uniformly sized fine particles, completing the pretreatment process.

[0023] The thermo-rheology synergistic module heats and softens crushed multi-slag and multi-aggregate raw materials while precisely controlling their moisture content to ensure good flowability and grindability. This module includes a thermal easing unit, a rheology and solids content detection unit, and an intelligent limited-quantity water addition unit. The thermal easing unit gently raises the temperature of the multi-slag and multi-aggregate raw materials to reduce hardness; examples include steam-jacketed easing devices, scraper heat exchangers, and water bath heaters. The rheology and solids content detection unit collects real-time data on the flow characteristics and solids content of the multi-slag and multi-aggregate raw materials; examples include combinations of online viscometers, Coriolis mass flow meters, and density detectors, and integrated rheology-solids content detection instruments. The intelligent limited-quantity water addition unit enables precise water replenishment; examples include combinations of water tanks, metering pumps, and spray heads, and intelligent flow control water addition devices. All three units are installed in the same processing chamber or adjacent pipeline locations. The probe of the rheology and solids content detection unit is inserted into the channel through which the multi-slag and multi-aggregate raw material flows, and the discharge end of the intelligent limited water addition unit is aligned with the processing area of ​​the multi-slag and multi-aggregate raw material. During operation, the crushed multi-slag and multi-aggregate raw material enters the thermal softening unit for heating and softening. The rheology and solids content detection unit collects the flow characteristics and solid composition percentage data of the heated and softened multi-slag and multi-aggregate raw material in real time, and transmits the flow characteristics and solid composition percentage data to the control unit. The control unit determines the state of the multi-slag and multi-aggregate raw material based on the flow characteristics and solid composition percentage data. If water needs to be added, it instructs the intelligent limited water addition unit to add a quantitative amount of water to the multi-slag and multi-aggregate raw material, ultimately obtaining a stable heated and softened multi-slag and multi-aggregate raw material.

[0024] The two-stage wet grinding closed-loop module is used to progressively grind multi-slag and multi-bone raw materials after heating and softening to achieve a preset particle size, while simultaneously recirculating and grinding any substandard multi-slag and multi-bone raw materials. The two-stage wet grinding closed-loop module includes a primary wet grinding unit, a secondary wet grinding unit, and a closed-loop reflux unit. The primary wet grinding unit is used for initial grinding of the multi-slag and multi-bone raw materials and can employ a toothed bone paste mill, a needle-disc bone paste mill, or a single-screw wet mill. The secondary wet grinding unit is used for fine grinding of the multi-slag and multi-bone raw materials and can employ a colloid mill, a needle-disc mill, or a wet bead mill. The closed-loop reflux unit is used to achieve recirculating grinding of substandard multi-slag and multi-bone raw materials and can employ a combination of a three-way proportional valve and a loop mixer, or an intelligent diversion reflux device. The discharge port of the primary wet grinding unit is connected to the inlet of the secondary wet grinding unit via a pipeline. The discharge port of the secondary wet grinding unit is divided into two paths: one path connects to the finished product channel, and the other path connects back to the inlet of the secondary wet grinding unit through a closed-loop reflux unit. During operation, the heated and softened multi-slag and multi-aggregate raw material first enters the primary wet grinding unit for preliminary grinding, forming preliminary wet abrasive. The preliminary wet abrasive flows into the secondary wet grinding unit for fine grinding. The finely ground multi-slag and multi-aggregate raw material is first tested by an online particle size detection unit. If it meets the standard, it enters the finished product channel; if it does not meet the standard, it flows back to the secondary wet grinding unit through the closed-loop reflux unit for further fine grinding.

[0025] The online detection and control module is used to collect processing data throughout the entire process and dynamically adjust the operating parameters of each module to ensure stable processing. The online detection and control module includes an online particle size detection unit and a control unit. The online particle size detection unit is used to detect the particle size of raw materials with multiple slag and aggregate components, and can employ a laser particle size analyzer, online sieve particle size detector, etc. The control unit is the device for overall process control and can employ a PLC controller, industrial computer, embedded intelligent control module, etc.

[0026] The hygienic cleaning unit is a device used to regularly clean the internal pipelines and processing chambers of each module of the system, reducing the problems of residual and deteriorated raw materials with a lot of slag and bone or clogging of pipelines. For example, high-pressure spray cleaning devices and CIP online cleaning devices can be used.

[0027] Rheological properties and solids content data are the core test data combination used to determine the processing suitability of multi-slag and multi-bone raw materials. Rheological properties data are mechanical parameters reflecting the flowability of multi-slag and multi-bone raw materials, and can include the viscosity (dynamic viscosity, kinematic viscosity), yield stress, flow index, etc., directly reflecting whether the multi-slag and multi-bone raw materials are easy to pump and wet grind. Solids content data are the proportion of water-insoluble solid components (bones, meat residue, connective tissue, etc.) in the total mass or volume of the multi-slag and multi-bone raw materials, and can include solid mass fraction, solid volume fraction, etc.

[0028] The heating state of the thermal retardation unit refers to the set of operating parameters that can be controlled by the control unit during the process of heating and softening the polyslag and polyaggregate raw materials. These parameters may include heating temperature (the softening temperature that the polyslag and polyaggregate raw materials need to reach), heating rate (the rate of temperature rise of the polyslag and polyaggregate raw materials per unit time), holding time (the time to maintain the polyslag and polyaggregate raw materials at the target temperature), and flow rate / pressure of the heating medium (such as the supply flow rate and pressure of steam in a steam jacket retarder).

[0029] The intelligent limited water supply unit includes the water supply flow rate, water supply timing, and total water supply to maintain the optimal moisture content of the multi-slag and multi-bone raw materials.

[0030] The operating parameters of the secondary wet grinding unit refer to the set of adjustable parameters that affect the fine grinding effect of the secondary wet grinding unit, including grinding speed, grinding gap, feed rate, grinding chamber temperature, etc.

[0031] The reflux state of a closed-loop reflux unit refers to the set of parameters that can be adjusted during the process of splitting and refluxing substandard raw materials with multiple slags and aggregates. These parameters may include reflux ratio, reflux rate, mixing ratio, and splitting switching state.

[0032] As can be seen from the above, the continuous processing system for processing multi-slag and multi-aggregate raw materials provided in this application reduces the problems of module function confusion and disordered component coordination in traditional processing systems by clarifying the purpose of each module, fixed components and collaborative workflow. The sequentially connected pipeline design enables continuous processing of multi-slag and multi-aggregate raw materials, reducing particle size fluctuations caused by the retention of multi-slag and multi-aggregate raw materials. The linkage of detection and control of each module enables the processing parameters to be dynamically adjusted according to the state of multi-slag and multi-aggregate raw materials, significantly improving the system's operational stability. At the same time, the design of step-by-step crushing, two-stage wet grinding and closed-loop reflux improves the uniformity of product particle size, effectively improving the defects of poor product particle size consistency and unstable system operation in related technologies for continuous processing systems for processing multi-slag and multi-aggregate raw materials.

[0033] In some embodiments, the coarse crushing unit is a meat grinder, the fine crushing unit is a meat grinder, and the pretreatment module further includes a feeding pump for conveying the multi-residue and multi-bone raw materials processed by the fine crushing unit to the thermo-rheology co-processing module.

[0034] As you can understand, a meat grinder includes a feed hopper, a rotating blade assembly, a discharge grid, and a drive motor. The feed hopper receives and crushes raw materials with many impurities and bones. The rotating blade assembly consists of 3-6 high-speed steel blades. The discharge grid is a metal plate with circular through holes. The drive motor is a three-phase asynchronous motor. During operation, the drive motor drives the rotating blade assembly to rotate at high speed. The raw materials with many impurities and bones fall from the feed hopper into the blade assembly area, where they are cut and torn into coarse pieces by the blades. The coarse pieces must pass through the through holes of the discharge grid to be discharged, thus improving the uniformity of the particle size of the coarse pieces.

[0035] The meat grinder includes a screw feeder, a cutting disc, a perforated plate, and a drive motor. The screw feeder has stainless steel spiral blades used to push coarsely chopped material. The cutting disc is equipped with 4-8 sharp blades, and the perforated plate is a metal plate with circular through holes. During operation, the coarsely chopped material is discharged from the coarse crushing unit and falls into the feed inlet of the meat grinder through a pipeline. The screw feeder pushes the coarsely chopped material at a uniform speed to the cutting disc, and the drive motor drives the cutting disc to rotate at high speed. The blades and the perforated plate work together to further grind the coarsely chopped material into finer pieces. The perforated plate can be replaced with different hole diameters according to subsequent processing requirements.

[0036] The feed pump is the raw material conveying component of the pretreatment module. For example, it can be a positive displacement gear pump. The positive displacement gear pump includes a pump body, a drive gear, a driven gear, an inlet, and an outlet. The pump body is made of stainless steel, and the drive gear and driven gear mesh with each other. During operation, the inlet of the positive displacement gear pump is connected to the outlet of the fine crushing unit via a pipeline. The outlet is connected to the inlet of the thermal slagging unit of the thermo-rheology co-processing module via a pipeline. The drive motor drives the drive gear to rotate, and the suction force generated by the gear meshing draws the fine crushed material discharged from the fine crushing unit into the pump body. Then, the thrust of the rotating gear stably conveys the multi-slag, multi-aggregate raw material to the thermal slagging unit. The conveying flow rate can be adjusted by the control unit to reduce the accumulation of multi-slag, multi-aggregate raw materials in the pipeline or the problem of conveying interruption.

[0037] With this setup, the meat grinder improves the uniformity of coarse material particle size, the meat grinder achieves uniform fine material refining, and the feed pump stably transports raw materials with multiple residues and bones. The three work together to complete the step-by-step crushing and stable conveying process, which solves the problem of uneven particle size of raw materials with multiple residues and bones in traditional crushing and improves the stability of system operation.

[0038] Optionally, in some embodiments, the thermal retardation unit is a steam jacket retarder or a scraped heat exchanger, and the rheology and solids content detection unit includes an online viscometer, a Coriolis mass flow meter, and a density detector.

[0039] As can be understood, a steam jacketed retarder includes a jacketed tank, a steam inlet, a condensate outlet, a raw material inlet, a raw material outlet, and a temperature sensor. The jacketed tank is a double-layered stainless steel structure; the inner layer contacts the slag-and-aggregate raw material, while the outer layer forms the jacket cavity. The temperature sensor is installed inside the jacketed tank to monitor the temperature of the slag-and-aggregate raw material in real time. During operation, steam enters the jacket cavity through the steam inlet, indirectly exchanging heat with the slag-and-aggregate raw material inside the jacketed tank, heating it to a preset softening temperature. The condensate after heat exchange is discharged through the condensate outlet. The temperature sensor transmits the temperature data of the slag-and-aggregate raw material to the control unit, which adjusts the steam intake based on the data to stabilize the heating temperature.

[0040] The scraper heat exchanger includes a shell, a scraper rotor, a heating medium channel, a raw material channel, and a temperature sensor. The shell is made of stainless steel. The scraper rotor is installed inside the raw material channel, which is surrounded by the heating medium channel. The temperature sensor is installed at the outlet of the raw material channel. During operation, the slag and aggregate raw material flows within the raw material channel. The scraper rotor is driven by a motor to rotate, ensuring that the slag and aggregate raw material is evenly contacted with the inner wall of the heating medium channel, reducing localized overheating. The heating medium (such as hot water or steam) circulates within the heating medium channel, softening the slag and aggregate raw material through heat conduction. The temperature sensor provides real-time temperature data, and the control unit adjusts the flow rate of the heating medium to improve the uniformity of the softening effect.

[0041] The core component of the online viscometer is a rotary detection probe. The probe is inserted into the polyslag and polyaggregate raw material. By measuring the resistance of the polyslag and polyaggregate raw material to the rotation of the probe, the viscosity value (i.e., rheological property data) of the polyslag and polyaggregate raw material is calculated, and the data is transmitted to the control unit in real time.

[0042] A Coriolis mass flow meter consists of a measuring tube, a drive coil, and a detection coil. When a raw material with a high content of slag and aggregate flows through the measuring tube, the drive coil causes the measuring tube to vibrate, and the detection coil measures the change in vibration frequency to calculate the mass flow rate of the raw material.

[0043] The density detector includes a gamma-ray emission source and a detector. When gamma rays pass through the polyslag and polyaggregate raw material, some rays are absorbed. The detector detects the intensity of the transmitted rays and calculates the density of the polyslag and polyaggregate raw material based on the intensity change.

[0044] This configuration allows both implementations of the thermal easing unit to achieve uniform and gentle heating of the multi-slag and multi-aggregate raw materials, reducing the problem of uneven softening or denaturation caused by local overheating and improving the stability of the rheological properties of the raw materials. The rheology and solids content detection unit, through the collaborative work of the three types of components, achieves real-time and accurate acquisition of rheological and solids content data, providing a reliable basis for moisture control. The intelligent limited water addition unit precisely controls the moisture content of the raw materials, reducing the situation where the multi-slag and multi-aggregate raw materials are too dry (poor flowability, pipe blockage) or too wet (low solids content, particle size fluctuation), ensuring that the multi-slag and multi-aggregate raw materials are always in the optimal state for wet grinding. The coordinated heating and softening, data detection, and precise water replenishment process reduces the impact of the state fluctuations of the multi-slag and multi-aggregate raw materials on subsequent processing, improving both product particle size consistency and system operational stability.

[0045] Optionally, the primary wet grinding unit is a toothed bone paste mill or a needle-disc bone paste mill. The body of the primary wet grinding unit is made of 316L material, and the mill body lining is made of cemented carbide or zirconia ceramic. The outlet of the primary wet grinding unit is equipped with a magnetic trap and a metal detection device. The secondary wet grinding unit is a colloid mill, a needle-disc mill, or a wet bead mill. The secondary wet grinding unit is equipped with a circulation sleeve.

[0046] It is understandable that preliminary wet grinding refers to the first grinding process of multi-slag and multi-aggregate raw materials after heat-rheology co-treatment, in order to reduce the hardness and particle size of the multi-slag and multi-aggregate raw materials.

[0047] The toothed bone and sludge mill includes a fixed grinding disc, a moving grinding disc, a drive motor, a feed inlet, and a discharge outlet. The fixed and moving grinding discs are circular metal discs arranged opposite each other, with interlocking annular toothed grooves on their surfaces. During operation, the multi-slag and multi-bone raw material enters the gap between the fixed and moving grinding discs through the feed inlet (the gap is adjustable). The drive motor drives the moving grinding disc to rotate at high speed, and the multi-slag and multi-bone raw material is ground finely by the shearing and grinding forces of the toothed grooves. The finely ground multi-slag and multi-bone raw material is discharged from the discharge outlet.

[0048] The needle-plate type bone paste mill includes a fixed needle plate, a moving needle plate, a drive motor, a feed inlet, and a discharge outlet. Both the fixed and moving needle plates are fixed with an array of hard alloy needles. During operation, the multi-slag and multi-bone raw material enters between the two needle plates. The moving needle plate rotates at high speed, and the needles impact, shear, and grind the multi-slag and multi-bone raw material, crushing and grinding it before it is discharged.

[0049] The grinding body liner is the surface material of the working surface or raw material contact area of ​​the stationary and moving grinding discs. It is made of cemented carbide (such as tungsten-cobalt alloy) or zirconia ceramic to reduce the decrease in grinding accuracy caused by grinding body wear, and at the same time reduce the mixing of metal debris into the slag and aggregate raw materials.

[0050] The magnetic collector is an impurity removal component in the primary wet grinding unit. It is installed in the discharge pipe of the primary wet grinding unit and includes a stainless steel shell and an internal strong magnetic core. During operation, when the raw material with a lot of slag and aggregate flows through the magnetic collector, the ferromagnetic impurities that may be contained in it (such as blade debris that falls off during crushing and metal particles generated by equipment wear) are attracted by the strong magnetic core, reducing the possibility of impurities entering subsequent equipment and damaging the grinding media or affecting product quality.

[0051] The metal detection device is a secondary impurity removal component in the primary wet grinding unit. Installed downstream of the magnetic trap, it includes a detection coil, a signal processor, and an alarm device. During operation, the detection coil generates an alternating magnetic field. When the multi-slag, multi-bone raw material flows through this field, if it contains metallic impurities (regardless of whether they are ferromagnetic), it will cause magnetic field distortion. Upon detecting the distortion signal, the signal processor sends an alarm message to the control unit. The control unit can then instruct the system to stop and clean the impurities, thereby improving the purity of the multi-slag, multi-bone raw material.

[0052] Fine wet grinding refers to a second deep grinding process on the raw materials after the initial wet grinding, grinding the initial wet abrasive to the finished particle size (which can be adjusted according to requirements).

[0053] The colloid mill consists of a stator, a rotor, an adjustment mechanism, and a drive motor. The stator and rotor have a conical structure, and the working surfaces are equipped with fine teeth. During operation, the slag and aggregate raw material enters the tiny gap between the stator and rotor. The rotor rotates at high speed, generating strong shearing force, grinding force, and turbulence, which grinds the slag and aggregate raw material into an ultrafine powder.

[0054] The needle disc mill consists of a fixed needle disc, a rotating needle disc, and a housing. The needle teeth on the needle disc are finer than those in the primary wet grinding unit. During operation, the initial wet abrasive is further ground to the target particle size through high-speed impact and shearing of the fine needle teeth.

[0055] A wet bead mill includes a grinding chamber, grinding beads, a stirrer, and a separating screen. During operation, the raw materials with a lot of slag and bone are mixed with the grinding beads in the grinding chamber. The stirrer rotates at high speed, causing the grinding beads to impact and rub against the raw materials with a lot of slag and bone, thereby achieving ultra-fine grinding. The separating screen is used to prevent the grinding beads from being discharged with the raw materials with a lot of slag and bone.

[0056] The circulating sleeve is a cooling component of the secondary wet grinding unit. It is a double-layered sleeve structure that wraps around the grinding chamber of the secondary wet grinding unit, including the sleeve body, a cooling medium inlet, and a cooling medium outlet. During operation, the cooling medium (such as cooling water or cooling oil) enters the sleeve jacket through the inlet and exchanges heat with the grinding chamber, carrying away the heat generated during the grinding process (shearing and friction during wet grinding will cause a temperature rise). This maintains the internal temperature of the grinding chamber at a preset temperature, reducing the problem of denaturation (such as protein denaturation) of heavy slag and heavy aggregate raw materials due to excessive temperature, while also protecting the grinding components from aging due to high temperatures.

[0057] This design allows the primary wet grinding unit to achieve both initial refinement of the multi-slag and multi-aggregate raw materials and improve their purity through a combination of coarse grinding and impurity removal. The selection of wear-resistant materials extends the equipment's service life and ensures the stability of grinding precision over long-term processing. The secondary wet grinding unit, through high-speed fine grinding and cooling protection, achieves deep refinement of the multi-slag and multi-aggregate raw materials, reducing the risk of deformation or particle size inconsistency caused by overheating during grinding. The two-stage design of preliminary and fine wet grinding gradually reduces the particle size of the multi-slag and multi-aggregate raw materials, significantly improving the consistency of product particle size. At the same time, the impurity removal device and cooling components reduce the risk of equipment failure and processing interruption, enhancing the stability of system operation.

[0058] For example, the closed-loop reflux unit includes a three-way proportional valve and a loop mixer. The three-way proportional valve is used to divert the multi-slag and multi-aggregate raw material after fine wet grinding in the two-stage wet grinding unit, and the loop mixer is used to mix the multi-slag and multi-aggregate raw material that has not met the preset particle size requirement with the multi-slag and multi-aggregate raw material after being treated by the thermal retardation unit.

[0059] It is understandable that closed-loop reflux refers to a recycling mechanism that re-introduces the slag and aggregate raw materials discharged from the secondary wet grinding unit that do not meet the preset particle size requirements into the processing flow for secondary fine wet grinding.

[0060] The three-way proportional valve is a flow-diverting component of the closed-loop reflux unit, comprising a valve body, valve core, drive motor, and position sensor. The valve body has a three-way structure, the drive motor is electrically connected to the control unit, and the position sensor is used to detect the position of the valve core. During operation, the online particle size detection unit detects the particle size of the finely wet-milled multi-slag and multi-aggregate raw material and transmits the data to the control unit. If the particle size meets the preset requirements, the control unit instructs the drive motor to rotate the valve core, causing the multi-slag and multi-aggregate raw material to flow out from the finished product outlet. If the preset requirements are not met, the valve core switches to the reflux outlet, allowing the substandard multi-slag and multi-aggregate raw material to flow into the loop mixer. The flow-diverting ratio can be adjusted by the valve core opening (0%-100%).

[0061] The loop mixer is the raw material mixing component of the closed-loop reflux unit, including a mixing chamber, a stirring paddle, two feed inlets, and a discharge outlet. The stirring paddle is installed inside the mixing chamber and driven by a micro motor. During operation, substandard multi-slag and multi-aggregate raw materials enter the mixing chamber through one feed inlet, while fresh, softened multi-slag and multi-aggregate raw materials, after being treated by the heat-modification unit, enter through the other feed inlet. The stirring paddle rotates at low speed, thoroughly mixing the two types of multi-slag and multi-aggregate raw materials to ensure uniform particle size and moisture content. The mixed multi-slag and multi-aggregate raw materials flow out through the discharge outlet and are returned to the feed inlet of the secondary wet grinding unit for secondary fine wet grinding.

[0062] The preset particle size requirement is a target particle size range set according to the intended use of the product. For example, when processing bone paste for use as a food additive, the preset particle size requirement is 50-80μm; when processing meat and bone paste for use as feed, the preset particle size requirement is 80-100μm.

[0063] This configuration, through the precise flow division of the three-way proportional valve and the uniform mixing of the loop mixer, forms a particle size correction mechanism without dead angles. This solves the problem of poor product consistency caused by the direct discharge of some non-standard slag and non-aggregate raw materials that do not meet the particle size requirements in traditional processing. The non-standard slag and non-aggregate raw materials are mixed with fresh softened slag and non-aggregate raw materials before grinding, which reduces the excessive refinement or denaturation of the non-standard slag and non-aggregate raw materials caused by repeated grinding, and ensures the uniformity of product particle size. In addition, the closed-loop design eliminates the need to stop the machine to clean up the non-standard slag and non-aggregate raw materials, realizing continuous cyclic processing and improving the continuous operation capability and stability of the system.

[0064] Please see Figure 2 and Figure 4 This application also provides a continuous processing method for processing raw materials with multiple slag and aggregate content, applied to a continuous processing system for processing such raw materials. The method includes: S1000, through the coarse crushing unit and fine crushing unit of the pretreatment module, crushes the multi-slag and multi-aggregate raw material in stages to obtain the crushed multi-slag and multi-aggregate raw material.

[0065] It is understandable that the crushed multi-grain raw material is a raw material with uniform particle size and no large hard impurities after continuous processing by the coarse crushing unit and fine crushing unit. The particle size range is suitable for the heating and softening of the thermal retardation unit and subsequent wet grinding processing, and will not cause insufficient heating or equipment blockage due to excessive particle size.

[0066] For example, a multi-grained raw material (such as a mixture of chicken bones and meat scraps) is fed into the coarse crushing unit (such as a meat grinder) of the pretreatment module. The coarse crushing unit performs preliminary cutting and crushing of the multi-grained raw material at a preset speed to form coarse material with medium particle size. The coarse material flows into the fine crushing unit (such as a meat grinder) through a pipeline. The fine crushing unit performs secondary crushing of the coarse material at an appropriate speed and aperture parameters to finally obtain a multi-grained raw material with uniform particle size after crushing.

[0067] The S2000 heats and softens the crushed multi-slag and multi-bone raw material through the thermal moderating unit of the thermal-rheology synergistic module, obtaining the softened multi-slag and multi-bone raw material. At the same time, the rheology and solids content detection unit of the thermal-rheology synergistic module collects the rheological characteristics and solids content data of the softened multi-slag and multi-bone raw material in real time. Then, the intelligent limited water addition unit of the thermal-rheology synergistic module adds a limited amount of water to the softened multi-slag and multi-bone raw material based on the rheological characteristics and solids content data, obtaining the multi-slag and multi-bone raw material with added water.

[0068] It is understandable that heating and softening is a process in which the heat-reducing unit raises the temperature of the crushed multi-grain raw material to a preset softening temperature through gentle heating, thereby softening the bones, meat residue, and connective tissue in the multi-grain raw material, reducing its hardness and brittleness, and improving its fluidity and grindability.

[0069] The softened multi-residue and multi-bone raw material is one that has reached the preset softening temperature, softened in texture, and has not undergone denaturation. Limited water addition refers to the intelligent limited water addition unit precisely adding the required amount of water based on real-time data collected by the rheology and solids content detection unit. This ensures that the multi-residue and multi-bone raw material is neither too dry, resulting in poor flowability, nor too wet, resulting in excessively low solids content, thus maintaining the raw material in its optimal processing state.

[0070] The raw material with added moisture is a material whose rheological properties and solid content are within the range suitable for subsequent wet grinding after heating, softening and precise water replenishment.

[0071] The S3000 uses a first-stage wet grinding unit of a two-stage wet grinding closed-loop module to perform preliminary wet grinding on the polyslag and polybone raw material after adding water, to obtain the preliminary wet-ground polyslag and polybone raw material. Then, the second-stage wet grinding unit of the two-stage wet grinding closed-loop module performs fine wet grinding on the preliminary wet-ground polyslag and polybone raw material, to obtain the finely wet-ground polyslag and polybone raw material.

[0072] It is understandable that the raw material with multiple slags and aggregates after preliminary wet milling refers to the raw material with a significantly reduced particle size and more uniform texture after processing by the first-stage wet milling unit, without obvious hard particles. The raw material with multiple slags and aggregates after fine wet milling refers to the raw material with a uniform and fine particle size that meets the preset particle size requirements after processing by the second-stage wet milling unit, which can be used as a finished product or raw material to be tested.

[0073] For example, the polystyrene and polybacterial raw material with added moisture enters the first-stage wet grinding unit (such as a toothed bone paste mill) of the two-stage wet grinding closed-loop module through a pipeline. The control unit instructs the first-stage wet grinding unit to operate at a preset speed and grinding gap. Through the shearing and grinding action of the mill body, the polystyrene and polybacterial raw material with added moisture is initially ground into a pre-wet-ground polystyrene and polybacterial raw material. The pre-wet-ground polystyrene and polybacterial raw material flows into the second-stage wet grinding unit (such as a colloid mill) through a pipeline. The control unit adjusts the speed and grinding gap of the second-stage wet grinding unit according to the state of the pre-wet-ground polystyrene and polybacterial raw material, so that the pre-wet-ground polystyrene and polybacterial raw material is subjected to strong shearing and grinding action in the mill body, and is further refined into a finely wet-ground polystyrene and polybacterial raw material with uniform particle size.

[0074] The S4000 uses the online particle size detection unit of the online detection and control module to detect the particle size of the finely wet-milled polyslag and polyabrasive raw material. If the finely wet-milled polyslag and polyabrasive raw material does not meet the preset particle size requirement, the closed-loop reflux unit of the two-stage wet milling closed-loop module mixes the finely wet-milled polyslag and polyabrasive raw material that does not meet the preset particle size requirement with the heated and softened polyslag and polyabrasive raw material to obtain the mixed polyslag and polyabrasive raw material. The mixed polyslag and polyabrasive raw material is then refluxed to the secondary wet milling unit for fine wet milling again.

[0075] It is understandable that the finely wet-milled raw material with multiple slag and aggregate that does not meet the preset particle size requirements is raw material whose particle size exceeds the preset range and does not meet the requirements of the finished product after being detected by the online particle size detection unit.

[0076] The mixed multi-slag and multi-bone raw material is formed by mixing substandard multi-slag and multi-bone raw material with fresh heated and softened multi-slag and multi-bone raw material in a preset ratio. Its particle size and state are suitable for the reprocessing of the secondary wet grinding unit, reducing the problem of over-refinement or deformation caused by repeated grinding of substandard multi-slag and multi-bone raw material.

[0077] For example, the finely wet-milled polyslag and polyabrasive raw material flows through the online particle size detection unit (such as a laser particle size analyzer) of the online detection and control module. The online particle size detection unit detects the particle size distribution data of the finely wet-milled polyslag and polyabrasive raw material in real time and transmits it to the control unit. The control unit compares the detection results with the preset particle size requirements. If the detection results show that the finely wet-milled polyslag and polyabrasive raw material does not meet the requirements, the control unit instructs the closed-loop reflux unit (composed of a three-way proportional valve and a loop mixer) of the two-stage wet milling closed-loop module to start. The three-way proportional valve switches the flow direction to introduce the substandard finely wet-milled polyslag and polyabrasive raw material into the loop mixer. At the same time, fresh heated and softened polyslag and polyabrasive raw material enters the loop mixer according to a preset ratio. The two are fully mixed in the mixer by the stirring paddle to form a mixed polyslag and polyabrasive raw material. The mixed polyslag and polyabrasive raw material flows back to the secondary wet milling unit through the pipeline. The control unit adjusts the operating parameters of the secondary wet milling unit and performs fine wet milling on the mixed polyslag and polyabrasive raw material again until the polyslag and polyabrasive raw material meets the preset particle size requirements.

[0078] The S5000, through the control unit of the online detection and control module, combined with the detection results of the online particle size detection unit, rheological characteristics, and solid content data, regulates the heating state of the thermal retardation unit, the water addition of the intelligent limited water addition unit, the operating parameters of the secondary wet grinding unit, and the reflux state of the closed-loop reflux unit.

[0079] For example, the control unit of the online detection and control module receives particle size data from the online particle size detection unit and rheological characteristics and solid content data from the rheological and solid content detection unit in real time. It integrates and analyzes the data through a preset algorithm: if the viscosity of the multi-slag and multi-aggregate raw material is too high or the solid content is too high, the control unit instructs the intelligent limited water addition unit to appropriately increase the amount of water added, while fine-tuning the heating temperature of the thermal retardation unit to improve the fluidity of the multi-slag and multi-aggregate raw material; if the finished product particle size is too coarse, the control unit instructs the secondary wet grinding unit to increase the grinding speed and reduce the grinding gap, while adjusting the reflux ratio of the closed-loop reflux unit to increase the number of reflux grinding times for the non-compliant multi-slag and multi-aggregate raw material; if the multi-slag and multi-aggregate raw material is found to be stable and the finished product particle size is qualified, the control unit maintains the current operating parameters of each module to ensure continuous stability of the processing process. The entire control process forms a closed-loop control with full-process data linkage.

[0080] As can be seen from the above, the continuous processing method for processing raw materials with multiple slags and aggregates provided in this application constructs a continuous processing link with pretreatment, thermo-rheological synergy, two-stage wet grinding closed loop, and full-process control. The steps are coordinated and connected, and the data is linked in real time. This effectively solves the problems of poor product particle size consistency and insufficient system operation stability caused by the disconnection of the processing process and the lag in parameter control in related technologies, and significantly improves the reliability and product quality of continuous processing of raw materials with multiple slags and aggregates.

[0081] In some embodiments, see Figure 3The S2000 uses a thermal softening unit within a thermal-rheology synergistic module to heat and soften the crushed multi-slag, multi-bone raw material, obtaining a softened multi-slag, multi-bone raw material. Simultaneously, the rheology and solids content detection unit of the thermal-rheology synergistic module collects real-time rheological properties and solids content data of the softened multi-slag, multi-bone raw material. Then, based on the rheological properties and solids content data, the intelligent limited water addition unit of the thermal-rheology synergistic module adds a limited amount of water to the softened multi-slag, multi-bone raw material, obtaining a multi-slag, multi-bone raw material with added water, including: S2100 controls the thermal easing unit to heat and soften the crushed multi-slag and multi-aggregate raw material. When the temperature of the crushed multi-slag and multi-aggregate raw material reaches the heating temperature linkage threshold, the rheology and solids content detection unit is activated.

[0082] It is understandable that the heating temperature linkage threshold is a preset temperature critical value that matches the softening characteristics of multi-slag and multi-aggregate raw materials. Its function is to trigger the start of the rheology and solids content detection unit, so that the multi-slag and multi-aggregate raw materials have basic fluidity when the rheology and solids content detection unit is started, and the collected data can truly reflect the processing status of the raw materials. The heating temperature linkage threshold needs to be preset according to the type of multi-slag and multi-aggregate raw materials and processing requirements and can be adjusted through the control unit.

[0083] For example, the control unit first issues a heating command to the thermal stabilization unit, which regulates the thermal stabilization unit to increase the temperature of the multi-slag and multi-bone raw material at a preset uniform heating rate. At the same time, the temperature sensor built into the thermal stabilization unit collects the temperature data of the multi-slag and multi-bone raw material in real time and feeds it back to the control unit. The control unit continuously compares the real-time temperature data with the preset heating temperature linkage threshold. When the real-time temperature reaches the heating temperature linkage threshold, it immediately sends a start command to the rheology and solids content detection unit through an electrical signal, triggering the detection unit to start data acquisition synchronously.

[0084] The S2200 continuously collects the rheological properties and solid content data of the multi-slag and multi-bone raw materials during the heating and softening process at preset time intervals through the rheology and solid content detection unit, and filters out abnormal data to generate a valid data sequence.

[0085] It is understandable that the preset time interval is a fixed time period between two data acquisitions, preset based on the heating and softening rate of the multi-slag and multi-bone raw material and the sensitivity of data changes. The purpose is to fully capture the state changes of the multi-slag and multi-bone raw material and reduce the omission of key data due to excessively long intervals or the data redundancy caused by excessively short intervals.

[0086] Abnormal data refers to invalid data that deviates from the normal data distribution range due to environmental interference, instantaneous equipment fluctuations, or other factors not caused by changes in the state of the multi-slag, multi-aggregate raw materials themselves. Valid data sequences are continuous sets of data arranged chronologically after filtering for abnormal data, accurately reflecting the rheological properties and solid content trends of multi-slag, multi-aggregate raw materials.

[0087] For example, the control unit first presets the data acquisition time interval, and instructs the rheology and solids content detection unit to continuously acquire rheological properties and solids content data of the multi-slag and multi-aggregate raw material at this time interval. After acquisition, the acquired raw data is filtered according to preset abnormal data filtering rules (such as statistical threshold filtering, trend consistency verification, etc.) to remove invalid abnormal data. The remaining valid data is arranged in chronological order of acquisition time to form a continuous valid data sequence. For example, if the preset data acquisition time interval is 15 seconds, the control unit instructs the detection unit to continuously acquire data such as viscosity and solids mass fraction of the multi-slag and multi-aggregate raw material at 15-second intervals. After acquiring 20 sets of data, abnormal data with sudden increases or decreases are filtered out according to the rule of exceeding the mean ± 3 times the standard deviation, and the remaining data is sorted by acquisition time to form a valid data sequence.

[0088] S2300 dynamically updates the pumpable characteristic adaptation range of multi-slag and multi-bone raw materials during the heating and softening process based on the effective data sequence. It compares the effective data sequence with the current pumpable characteristic adaptation range to determine whether the multi-slag and multi-bone raw materials during the heating and softening process are in a pumpable state and the required amount of water to be added.

[0089] It is understandable that the pumpable characteristic adaptation range is the range of rheological properties and solid content data that the multi-slag and multi-aggregate raw materials can be smoothly transported through the pipeline and adapted to the subsequent wet grinding process. This pumpable characteristic adaptation range is not a fixed value, but is dynamically adjusted by the control unit based on the actual state of the multi-slag and multi-aggregate raw materials in the effective data sequence, so as to adapt to the real-time state of the multi-slag and multi-aggregate raw materials.

[0090] Pumpable state means that the rheological properties and solid content of the raw material with multiple slags and aggregates both fall within the current range of pumpable properties, and it has good fluidity and processability.

[0091] The required amount of water to be added refers to the amount of water needed to adjust the multi-slag and multi-bone raw materials from a state that is not currently pumpable to a pumpable state. It is calculated by measuring the deviation between the current data and the suitable range.

[0092] For example, the control unit first presets the number of valid data accumulation sets. After accumulating a certain number of valid data sets, it initiates an update of the pumpable characteristic adaptation interval. For instance, it uses a sliding window algorithm or linear regression algorithm to analyze the changing trend of the valid data sequence. Based on the statistical distribution characteristics of the data (such as mean and standard deviation), it adjusts the upper and lower limits of the pumpable characteristic adaptation interval according to the principle of covering the vast majority of valid data. Then, it compares the latest collected valid data with the updated pumpable characteristic adaptation interval item by item to determine whether the rheological properties and solids content data both fall within the interval. If not... The deviation is calculated using the absolute deviation method (rheological property deviation = current rheological data - median of the pumpable property adaptation range, solid content deviation = current solid content - median of the pumpable property adaptation range). Based on the fundamental relationship that the amount of water added is inversely proportional to the change in solid content (increasing water will decrease solid content, and vice versa), combined with the total mass of the multi-slag and multi-bone raw materials and the degree of solid content deviation, the amount of water to be added is initially estimated. Finally, the water volume range is corrected using the rheological property deviation (if the rheological data is too low, the water volume can be appropriately increased to improve fluidity).

[0093] S2400: If it is determined that the multi-slag and multi-bone raw material in the heating and softening process is not in a pumpable state, the intelligent limited water addition unit is controlled to add a preset amount of water to the multi-slag and multi-bone raw material in the heating and softening process. The rheological and solid content detection unit continuously collects the rheological characteristics and solid content data of the multi-slag and multi-bone raw material in the process of adding the preset amount of water, and performs abnormal data filtering on the collected rheological characteristics and solid content data of the multi-slag and multi-bone raw material in the process of adding the preset amount of water to obtain the rheological characteristics and solid content data of the added preset amount of water. Then, the rheological characteristics and solid content data of the preset amount of water are combined with the historical data trend of the effective data sequence for feedback correction, and the amount of water added is dynamically adjusted.

[0094] It is understandable that the preset water volume is a single water addition based on a preliminary estimate of the required water replenishment volume, in order to avoid over-flushing of the raw materials with multiple slags and bones due to excessive or insufficient water addition at one time. The preset water volume is usually a certain proportion of the required water replenishment volume.

[0095] Feedback correction refers to the control unit comparing the detection data after water addition with the historical trend of changes in the effective data sequence, analyzing the effect of water addition on the state of multi-slag and multi-bone raw materials, and then adjusting the subsequent water addition to form a closed-loop control logic.

[0096] S2500: When the rheological properties and solid content data of the added preset amount of water continuously fall within the current pumpable property adaptation range and the maintenance time reaches the preset stable threshold, the intelligent limited water addition unit is controlled to stop adding water, thus obtaining the multi-slag and multi-bone raw material after adding water.

[0097] It is understandable that the preset stability threshold is the shortest time for the rheological properties and solid content data of multi-slag and multi-aggregate raw materials to continuously fall within the range of pumpable characteristics. The purpose is to determine the stability of the multi-slag and multi-aggregate raw materials and reduce the situation of stopping water addition due to misjudgment caused by the instantaneous achievement of data standards.

[0098] The multi-residue and multi-bone raw material after adding water is heated and softened, and then precisely watered and controlled in a closed loop. Its rheological properties and solid content are stable within the range suitable for pumpability. It is a raw material with good pumpability and grindability and can be directly adapted to subsequent wet grinding.

[0099] For example, the control unit presets a time threshold range for the stability of rheological properties and solid content data. After adding a preset amount of water, it continuously monitors whether the rheological properties and solid content data of the multi-slag and multi-bone raw material fall within the current pumpable characteristic adaptation range. At the same time, a timer is started. When the rheological properties and solid content data continuously fall within the pumpable characteristic range and the timer duration reaches the preset stability threshold, the control unit immediately sends a stop command to the intelligent limited water addition unit to terminate the water addition process. If the rheological properties and solid content data exceed the adaptation range during the timer period, the timer is reset until the data continuously meets the preset stability threshold requirement, thus obtaining the multi-slag and multi-bone raw material after adding water.

[0100] By adopting the above steps S2100 to S2500, and by dynamically updating the pumpable characteristic adaptation range and feedback correction of the water addition, the fluctuation of the state of multi-slag and multi-bone raw materials caused by fixed parameter control is reduced, so that the multi-slag and multi-bone raw materials always have stable pumpability and grindability. This effectively solves the problems in related technologies such as uneven heating of multi-slag and multi-bone raw materials, poor fluidity caused by blind water addition, and fluctuation of wet grinding load.

[0101] In some embodiments, please refer to Figure 3 S2400, a smart limited water addition unit controls the addition of a preset amount of water to the multi-slag, multi-bone raw materials during the heating and softening process. A rheological and solids content detection unit continuously collects the rheological characteristics and solids content data of the multi-slag, multi-bone raw materials during the water addition process. Abnormal data is filtered from the collected data to obtain the rheological characteristics and solids content data for the preset water addition amount. This data is then combined with historical data trends from valid data sequences for feedback correction, dynamically adjusting the water addition amount, including: S2410, Step a: Based on the comparison results between the effective data sequence and the current pumpable characteristic adaptation range, the required amount of water to be added is obtained. Then, based on the required amount of water to be added and the preset ratio, the initial preset amount of water is determined, and the intelligent limited water addition unit is controlled to add the initial preset amount of water to the multi-slag and multi-bone raw materials in the heating and softening process at a uniform rate.

[0102] It is understandable that the initial preset water volume refers to the first water volume after the required supplementary water volume is converted according to the preset ratio. The purpose is to reduce the problem of over-flushing of raw materials with multiple slags and aggregates (such as excessively high humidity or excessively low solid content) caused by adding all the required water at once.

[0103] Uniform addition refers to the intelligent limited water addition unit adding an initial preset amount of water to the multi-slag and multi-bone raw materials at a fixed flow rate, so that the water is fully mixed with the multi-slag and multi-bone raw materials and the state of the multi-slag and multi-bone raw materials changes uniformly.

[0104] For example, the control unit calculates the amount of water needed to adjust the multi-slag and multi-bone raw materials to the appropriate range by comparing the valid data sequence with the current pumpable characteristic adaptation range; then it calculates the initial preset water volume according to the preset safety ratio (usually 60%-90%); then it sends a water addition command to the intelligent limited water addition unit, specifying the water addition flow rate and the total water addition volume, and controls the water addition unit to add the initial preset water volume at a fixed flow rate and at a uniform speed until the set total water addition volume is reached.

[0105] S2420, Step b: Control the rheology and solids content detection unit to continuously collect the rheological properties and solids content data of the multi-slag and multi-bone raw materials during the heating and softening process of adding the initial preset water volume, and filter the collected rheological properties and solids content data of the multi-slag and multi-bone raw materials during the heating and softening process of adding the initial preset water volume according to the preset abnormal data filtering rules, so as to obtain the rheological properties and solids content data of adding the initial preset water volume.

[0106] It is understandable that the preset abnormal data filtering rules are multi-dimensional joint filtering logics set for the data fluctuation characteristics during the water addition process. They usually include statistical threshold screening (such as range screening based on mean and standard deviation) and trend consistency verification (such as the rationality judgment based on the change trend of data before and after), so that the filtered data can truly reflect the impact of moisture on the state of multi-slag and multi-bone raw materials.

[0107] S2430, Step c: Based on the effective data sequence, extract the rheological properties of the multi-slag and multi-bone raw materials during the heating and softening process, as well as the historical change rate and stable interval boundary of the solid content data, to form historical trend analysis results.

[0108] It can be understood that the historical rate of change is the average rate of change of rheological properties and solid content data over time in the effective data sequence. Specifically, it is the amount of change of rheological properties and solid content data per unit time, which can reflect the changing trend of the state of raw materials with multiple slags and aggregates as the processing process (such as the speed at which viscosity gradually increases with heating time, and the rate at which solid content gradually decreases with the addition of water).

[0109] The stable interval boundary is the range of normal fluctuations in rheological properties and solids content data within an effective data sequence; that is, the maximum and minimum values ​​of data fluctuations, reflecting the stability of the multi-slag, multi-aggregate raw material state. Historical trend analysis results are an analysis report formed by integrating extracted historical change rates and stable interval boundaries. It serves as an important basis for judging the rationality of current multi-slag, multi-aggregate raw material state changes and the direction of subsequent water volume adjustments.

[0110] For example, the control unit uses a sliding window algorithm or a linear fitting algorithm to analyze and process the effective data sequence. According to the preset window size or data segment length, it calculates the change in rheological properties and solid data per unit time to obtain the historical change rate. At the same time, it counts the maximum and minimum values ​​of rheological properties and solid data in the effective data sequence to determine the stable interval boundary of normal data fluctuation. The historical change rate and stable interval boundary are integrated to form a complete historical trend analysis result.

[0111] S2440, Step d: Compare the rheological characteristics and solid content data of the added initial preset water volume with the current pumpable characteristic adaptation range to obtain the data deviation difference. At the same time, combine the historical trend analysis results to determine whether the initial preset water volume is insufficient, excessive, or unsuitable.

[0112] It can be understood that the data deviation difference is the difference between the rheological characteristic data of the multi-slag and multi-bone raw material and the rheological characteristic threshold range in the pumpable characteristic adaptation range after adding the initial preset water volume, and the difference between the solid content data and the solid content threshold range. A positive difference indicates that the data is higher than the pumpable characteristic range, and a negative difference indicates that it is lower than the pumpable characteristic range. The absolute value of the difference reflects the degree of deviation.

[0113] S2450, Step e: If it is determined that the initial preset water volume is insufficient, the incremental water volume to be supplemented is obtained based on the ratio of the data deviation difference to the historical change rate, and the intelligent limited water addition unit is controlled to continue adding water to the multi-slag and multi-bone raw materials in the heating and softening process according to the incremental water volume to be supplemented; if it is determined that the initial preset water volume is excessive, the required standing time is obtained based on the difference between the data deviation difference and the boundary of the stable interval, and the intelligent limited water addition unit is controlled to stop adding water and maintain the current standing time; if it is determined that the initial preset water volume is suitable, the intelligent limited water addition unit is controlled to continue adding water to the multi-slag and multi-bone raw materials in the heating and softening process at the current water addition rate.

[0114] It is understandable that the water volume increment is the amount of water that needs to be added when the initial preset water volume is insufficient, calculated by the ratio of the data deviation difference to the historical rate of change.

[0115] The settling time is the time required for the multi-slag and multi-bone raw material to maintain its current state when the initial preset water volume is excessive. It is calculated by the difference between the data deviation difference and the boundary of the stable range, allowing the multi-slag and multi-bone raw material to fully absorb water and stabilize its state.

[0116] For example, if the initial preset water volume is determined to be insufficient, the absolute value of the deviation difference between the rheological characteristics and solid content data is first taken and divided by the corresponding historical rate of change to obtain the time required for the two types of data to reach the adaptation range. The longer time is taken as a reference, and then combined with the total mass of the multi-slag and multi-bone raw materials and the ratio of solid content to water, the incremental water volume to be added is obtained. If it is determined to be excessive, the absolute value of the difference between the data deviation difference and the boundary of the stable range is calculated, and the settling time is determined according to the logic that the larger the difference, the longer the settling time. If it is suitable, the current water addition rate is maintained unchanged.

[0117] S2460, repeat steps a to e until the deviation between the rheological characteristics and solid content data of the initial preset water volume and the current pumpable characteristics adaptation range is less than the preset deviation threshold, complete the feedback correction, and determine the final water volume to be added.

[0118] It is understandable that the preset deviation threshold is the maximum deviation allowed between the rheological properties and solid content data and the range of pumpability characteristics. It is the final standard for judging whether the state of multi-slag and multi-aggregate raw materials meets the standard. The preset deviation threshold value is less than the allowable deviation of the range of pumpability characteristics.

[0119] For example, the control unit presets a deviation threshold. After each adjustment in step e is completed, it re-executes step a (calculates the required water replenishment based on the latest valid data) to step e (adjust water volume) and continuously monitors the data deviation difference. When the deviation difference is less than the preset deviation threshold and remains stable for a short time, the loop stops and the cumulative water replenishment is determined as the final water replenishment.

[0120] By adopting the above steps S2410 to S2460, and by combining the data deviation difference with historical trends, the water volume adjustment is made more targeted, so that the state of multi-slag and multi-bone raw materials is stable and close to the range of pumpable characteristics. This effectively solves the problem of flowability fluctuation of multi-slag and multi-bone raw materials caused by blind water addition and parameter control lag in related technologies, and improves the consistency of product particle size.

[0121] In some embodiments, S2420, the rheological properties and solid content data of the multi-slag and multi-bone raw materials collected during the heating and softening process of adding an initial preset amount of water are filtered for abnormal data according to a preset abnormal data filtering rule, to obtain the rheological properties and solid content data of the added initial preset amount of water, including: S2421, based on the effective data sequence, the mean and standard deviation of the rheological properties of the multi-slag and multi-bone raw materials during the heating and softening process are obtained respectively, and the mean and standard deviation of the solid content data are used as the benchmark for judging abnormal data.

[0122] It is understandable that the mean of rheological property data and the mean of solid data are the arithmetic mean of the corresponding data in the effective data sequence, reflecting the central tendency of the data.

[0123] The standard deviation of rheological property data and the standard deviation of solid content data represent the degree to which the corresponding data deviates from the mean, reflecting the dispersion of the data.

[0124] For example, the control unit extracts all rheological property data and solid data from the valid data sequence, calculates the arithmetic mean and standard deviation respectively, and stores the calculation results as the benchmark parameters for judging abnormal data.

[0125] S2422, the single set of rheological characteristic data of the multi-slag and multi-bone raw materials in the heating and softening process of adding the initial preset water volume is compared with the first preset statistical threshold range determined by the mean and standard deviation of the rheological characteristic data. If the single set of rheological characteristic data exceeds the first preset statistical threshold range, it is marked as abnormal rheological characteristic data.

[0126] It is understandable that the first preset statistical threshold range is a normal data distribution range set based on the mean and standard deviation of rheological characteristic data, usually the mean ± n times the standard deviation (n is a preset integer, such as 2 or 3), used to filter rheological characteristic data that exceed normal fluctuations.

[0127] Abnormal rheological characteristic data are invalid data in which a single set of rheological characteristic data exceeds the range of the first preset statistical threshold. They are mostly caused by detection interference or instantaneous fluctuations in equipment.

[0128] For example, the control unit first sets a first preset statistical threshold range (n is 2 or 3, adjusted according to data stability) based on the mean ± n times the standard deviation; then, each set of rheological characteristic data collected during the addition of the initial preset water volume is compared with the first preset statistical threshold range one by one; if the rheological characteristic data exceeds the first preset statistical threshold range, it is marked as abnormal rheological characteristic data.

[0129] S2423, the single set of solid content data of the multi-slag and multi-bone raw materials in the heating and softening process of adding the initial preset water volume is compared with the second preset statistical threshold range determined by the mean of solid content data and the standard deviation of solid content data. If the single set of solid content data exceeds the second preset statistical threshold range, it is marked as solid content abnormal data.

[0130] It is understandable that the second preset statistical threshold range is a normal data distribution range set based on the mean and standard deviation of the fixed data. The setting logic is the same as that of the first preset statistical threshold range, and it only applies to the fixed data.

[0131] Abnormal solid content data refers to invalid data where a single set of solid content data exceeds the range of the second preset statistical threshold. This is also caused by changes in the state of the non-slag and non-bone raw materials themselves.

[0132] For example, the control unit sets a second preset statistical threshold range (n is consistent with the first preset statistical threshold range) based on the solid content mean ± n times the solid content standard deviation; each set of collected solid content data is compared with the second preset statistical threshold range, and data exceeding the range is marked as solid content abnormal data.

[0133] S2424, compare the changing trends of the marked rheological characteristic anomaly data with the two adjacent sets of valid rheological characteristic data before and after the rheological characteristic anomaly data, and compare the changing trends of the solid content anomaly data with the two adjacent sets of valid solid content data before and after the solid content anomaly data. If the changing direction of the rheological characteristic anomaly data is opposite to the changing trend of the two adjacent sets of valid rheological characteristic data before and after the rheological characteristic anomaly data, and the changing magnitude exceeds the first preset magnitude threshold corresponding to the changing magnitude of the two adjacent sets of valid rheological characteristic data before and after the rheological characteristic anomaly data, then it is determined as rheological characteristic anomaly data to be removed; if the changing direction of the solid content anomaly data is opposite to the changing trend of the two adjacent sets of valid solid content data before and after the solid content anomaly data, and the changing magnitude exceeds the second preset magnitude threshold corresponding to the changing magnitude of the two adjacent sets of valid solid content data before and after the solid content anomaly data, then it is determined as solid content anomaly data to be removed.

[0134] It is understandable that trend comparison refers to judging whether the direction of change (upward / downward) of abnormal data is consistent with the direction of change of two adjacent valid data sets.

[0135] The first / second preset amplitude threshold refers to the maximum allowable amplitude set based on the variation amplitude of adjacent valid data (usually 1.5-3 times the adjacent variation amplitude). Abnormal data to be removed refers to abnormal data that simultaneously meets the conditions of opposite direction and amplitude exceeding the limit. Such data cannot reflect the true state of the raw materials and must be removed.

[0136] For example, for each set of marked abnormal data, first extract the two adjacent sets of valid data, calculate the direction of change of the two adjacent sets of valid data (e.g., the change increases from the front set to the middle set, or from the middle set to the back set, with an upward trend) and the magnitude of change (the absolute value of the back set data minus the front set data); then determine whether the direction of change of the abnormal data is opposite to this trend, and at the same time calculate the magnitude of change between the abnormal data and the previous set of valid data. If it exceeds the magnitude threshold of the adjacent change magnitude multiplied by a preset multiple, it is determined to be data that needs to be removed.

[0137] S2425 retains unlabeled rheological property data and solids content data, as well as rheological property abnormal data and solids content abnormal data that do not need to be removed after comparison, and integrates them to form rheological property and solids content data with the initial preset water volume.

[0138] It is understandable that outlier data that does not need to be removed are those that, although exceeding the statistical threshold, show a trend consistent with the preceding and following valid data and whose magnitude of change does not exceed the limit. This type of data may represent the true fluctuations in the state of the multi-slag and multi-bone raw materials and should be retained. Integration refers to arranging all retained data in chronological order of collection time to form a continuous and complete dataset that reflects the dynamic changes in the state of the multi-slag and multi-bone raw materials during the addition of the initial preset water volume.

[0139] For example, the control unit first filters out the normal rheological characteristic data and solid content data that are not labeled; then it retains the abnormal data that, after comparison by S2424, shows that the direction of change is consistent with the trend or the magnitude does not exceed the limit; finally, the two types of data are arranged in order of collection time, and duplicate data are removed to form continuous rheological characteristic and solid content data with the initial preset water volume added.

[0140] By adopting the above steps S2421 to S2425, the loss of effective data or the retention of abnormal data caused by single threshold filtering is reduced, providing high-quality data support for subsequent water volume adjustment and status judgment, improving the system data processing efficiency, indirectly enhancing the system operation stability, and providing data assurance for product particle size consistency.

[0141] In some embodiments, S2440, the rheological characteristics and solids content data of the added initial preset water volume are compared with the current pumpable characteristic adaptation range to obtain the data deviation difference. Simultaneously, combined with historical trend analysis results, it is determined whether the initial preset water volume is insufficient, excessive, or unsuitable, including: S2441, compare the rheological characteristic data of the added initial preset water volume with the rheological characteristic threshold range in the current pumpable characteristic adaptation interval to obtain the rheological characteristic deviation difference; compare the solid content data of the added initial preset water volume with the solid content threshold range in the current pumpable characteristic adaptation interval to obtain the solid content data deviation difference.

[0142] It is understandable that the rheological property threshold range is a specific numerical range (including upper and lower limits) set for rheological property data (such as viscosity) within the current pumpable property adaptation range, and is a specific standard for rheological property compliance.

[0143] The solids content threshold range is a specific numerical range set for solids content data within the current pumpable characteristic adaptation interval, and is a specific standard for achieving solids content targets. The rheological characteristic deviation difference / solids content data deviation difference refers to the difference between the actual data after adding the initial preset water volume and the median (or boundary value) of the corresponding threshold range, quantifying the gap between the state of multi-slag and multi-aggregate raw materials and the adaptation interval.

[0144] For example, the control unit first determines the rheological characteristic threshold range and solid content threshold range in the current pumpable characteristic adaptation range; calculates the rheological characteristic deviation difference = actual rheological data - median of the rheological characteristic threshold range, and the solid content data deviation difference = actual solid content data - median of the solid content threshold range; a positive difference indicates that the data is higher than the median of the current pumpable characteristic range, and a negative difference indicates that the data is lower than the median, and the larger the absolute value, the more serious the deviation.

[0145] S2442, based on the historical rate of change in the historical trend analysis results, determine whether the direction of change of the deviation difference of rheological properties and the deviation difference of solid content data is consistent with the trend of the historical rate of change.

[0146] It is understandable that the direction of change is the increase or decrease of the deviation difference in rheological properties and the deviation difference in solid content data as the initial preset water volume is added.

[0147] A consistent trend means that the direction of change is the same as the historical rate of change (e.g., if the historical rate of change is that the viscosity increases after adding water, the corresponding deviation of the rheological properties should gradually increase and move towards the median), indicating that the data change conforms to the natural law of processing raw materials with multiple slag and multiple aggregates.

[0148] For example, the control unit extracts the historical rate of change (such as viscosity gradually increasing with the addition of water and solid content gradually decreasing with the addition of water) from the historical trend analysis results, monitors the dynamic changes of the deviation difference of rheological properties and the deviation difference of solid content data during the process of adding the initial preset amount of water, and compares the changing direction of the deviation difference of rheological properties and the deviation difference of solid content data with the historical rate of change trend to determine whether they are consistent.

[0149] S2443, based on the stable interval boundary in the historical trend analysis results, determines whether the deviation difference of rheological properties and the deviation difference of solid data exceed the allowable deviation range corresponding to the stable interval boundary.

[0150] It is understandable that the allowable deviation range is the maximum allowable deviation range set based on the boundary of the stable interval. It is usually the boundary of the stable interval ± a certain percentage of the boundary value, used to distinguish between normal fluctuations and abnormal deviations, so as to avoid misjudgment caused by slight fluctuations in raw materials with multiple slags and aggregates. The allowable deviation range is greater than the threshold range of the pumpable characteristic adaptation interval.

[0151] For example, the control unit sets the allowable deviation range based on the stable interval boundary in the historical trend analysis results, calculates the absolute value of the deviation difference of rheological characteristics and the absolute value of the deviation difference of solid data after adding the initial preset water volume, and compares the absolute value of the deviation difference of rheological characteristics and the absolute value of the deviation difference of solid data with the corresponding allowable deviation range to determine whether it exceeds the limit.

[0152] S2444 If the deviation difference of rheological properties and the deviation difference of solid content data are both less than the allowable deviation corresponding to the current pumpable characteristic adaptation range, and the direction of change is the same as the historical change rate trend and does not exceed the allowable deviation range corresponding to the boundary of the stable range, then the initial preset water volume adaptation is determined.

[0153] For example, the control unit sets the allowable deviation corresponding to the current pumpable characteristic adaptation range, compares the absolute values ​​of the deviation difference of rheological characteristics and the deviation difference of solid data, and verifies that the change direction of the two types of differences is consistent with the historical trend. It confirms that they do not exceed the allowable deviation range of the stable range boundary. If all three conditions are met, the initial preset water volume is determined to be adapted.

[0154] S2445 If the deviation difference of rheological properties and the deviation difference of solid content data are both greater than the allowable deviation corresponding to the current pumpable characteristic adaptation range, and the direction of change is the same as the historical change rate trend and does not exceed the allowable deviation range corresponding to the boundary of the stable range, then it is determined that the initial preset water volume is insufficient.

[0155] For example, if the absolute values ​​of the deviation difference of rheological characteristics and the deviation difference of solid data are both greater than the allowable deviation, the control unit verifies that the direction of change of the two types of differences is the same as the historical trend (the difference gradually increases), confirms that they do not exceed the allowable deviation range of the stable interval boundary, and if all three conditions are met, it is determined that the initial preset water volume is insufficient.

[0156] S2446 If the deviation difference of rheological properties and the deviation difference of solid content data both exceed the allowable deviation range corresponding to the boundary of the stable interval, and the direction of change is opposite to the trend of historical change rate, then it is determined that the initial preset water volume is excessive.

[0157] For example, if the absolute values ​​of the deviation difference of rheological properties and the deviation difference of solid content data both exceed the allowable deviation range, the control unit verifies that the direction of change of the two types of differences is opposite to the trend of the historical change rate (from historical viscosity increase to current viscosity decrease, from historical solid content decrease to current solid content increase). If both conditions are met, it is determined that the initial preset water volume is excessive.

[0158] By adopting the above steps S2441 to S2446, the direction of water volume adjustment is made clearer through clear judgment conditions and quantitative standards, reducing the situation of blindly adding water or stopping water. This effectively solves the problem of fluctuation in the state of raw materials with multiple slags and aggregates caused by inaccurate water volume judgment in related technologies, improves the accuracy of system control, and thus improves the consistency of product particle size and the stability of system operation.

[0159] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.

The crushed multi-slag and multi-bone raw material is heated and softened by the thermal moderating unit of the thermal-rheology synergistic module to obtain the heated and softened multi-slag and multi-bone raw material. At the same time, the rheology and solid content detection unit of the thermal-rheology synergistic module collects the rheological characteristics and solid content data of the heated and softened multi-slag and multi-bone raw material in real time. Then, the intelligent limited water addition unit of the thermal-rheology synergistic module adds a limited amount of water to the heated and softened multi-slag and multi-bone raw material based on the rheological characteristics and solid content data to obtain multi-slag and multi-bone raw material with added water. The polystyrene and polybone raw material with added water is initially wet-milled by the first-stage wet-milling unit of the two-stage wet-milling closed-loop module to obtain the initially wet-milled polystyrene and polybone raw material. Then, the polystyrene and polybone raw material is finely wet-milled by the second-stage wet-milling unit of the two-stage wet-milling closed-loop module to obtain the finely wet-milled polystyrene and polybone raw material.

Simultaneously, the rheology and solids content detection unit of the thermo-rheology synergistic module collects the rheological properties and solids content data of the softened multi-slag and multi-bone raw material in real time. Then, the intelligent limited water addition unit of the thermo-rheology synergistic module adds a limited amount of water to the softened multi-slag and multi-bone raw material based on the rheological properties and solids content data to obtain a multi-slag and multi-bone raw material with added water, comprising: The thermal easing unit is controlled to heat and soften the crushed polyslag and polybone raw material. When the temperature of the crushed polyslag and polybone raw material reaches the heating temperature linkage threshold, the rheology and solids content detection unit is activated. The rheology and solids content detection unit continuously collects the rheological properties and solids content data of the multi-slag and multi-bone raw material during the heating and softening process at preset time intervals, and filters out abnormal data to generate a valid data sequence. Based on the effective data sequence, the pumpable characteristic adaptation range of the multi-slag and multi-bone raw material in the heating and softening process is dynamically updated. The effective data sequence is compared with the current pumpable characteristic adaptation range to determine whether the multi-slag and multi-bone raw material in the heating and softening process is in a pumpable state and the required amount of water to be added. If it is determined that the multi-slag and multi-bone raw material in the heating and softening process is not in the pumpable state, the intelligent limited water addition unit is controlled to add a preset amount of water to the multi-slag and multi-bone raw material in the heating and softening process. The rheological and solid content detection unit continuously collects the rheological characteristics and solid content data of the multi-slag and multi-bone raw material in the process of adding the preset amount of water, and performs abnormal data filtering on the collected rheological characteristics and solid content data of the multi-slag and multi-bone raw material in the process of adding the preset amount of water to obtain the rheological characteristics and solid content data of the added preset amount of water. Then, the rheological characteristics and solid content data of the preset amount of water are combined with the historical data trend of the effective data sequence for feedback correction, and the amount of water added is dynamically adjusted. When the rheological properties and solid content data of the added preset amount of water continuously fall within the current pumpable property adaptation range and the maintenance time reaches the preset stable threshold, the intelligent limited water addition unit is controlled to stop adding water, and the multi-slag and multi-bone raw material after adding water is obtained.

8. The continuous processing method for processing raw materials with multiple slag and aggregate content as described in claim 7, characterized in that, The intelligent limited water addition unit adds a preset amount of water to the multi-slag and multi-bone raw material during the heating and softening process. The rheological and solids content detection unit continuously collects the rheological characteristics and solids content data of the multi-slag and multi-bone raw material during the water addition process. Abnormal data is filtered from the collected data to obtain the rheological characteristics and solids content data for the preset water addition amount. This data is then combined with historical data trends from the valid data sequence for feedback correction, dynamically adjusting the water addition amount. This includes: Step a: Based on the comparison results between the effective data sequence and the current pumpable characteristic adaptation range, the required amount of water to be added is obtained. Then, based on the required amount of water to be added and the preset ratio, the initial preset amount of water is determined, and the intelligent limited water addition unit is controlled to add the initial preset amount of water to the multi-slag and multi-bone raw materials in the heating and softening process at a uniform rate. Step b: Control the rheology and solids content detection unit to continuously collect the rheological properties and solids content data of the multi-slag and multi-bone raw materials during the heating and softening process of adding the initial preset water volume, and filter the collected rheological properties and solids content data of the multi-slag and multi-bone raw materials during the heating and softening process of adding the initial preset water volume according to the preset abnormal data filtering rules, so as to obtain the rheological properties and solids content data of adding the initial preset water volume. Step c: Based on the effective data sequence, extract the historical change rate and stable interval boundary of the rheological properties and solid content data of the multi-slag and multi-bone raw materials during the heating and softening process to form historical trend analysis results; Step d: Compare the rheological characteristics and solid content data of the added initial preset water volume with the current pumpable characteristic adaptation range to obtain the data deviation difference. At the same time, combine the historical trend analysis results to determine whether the initial preset water volume is insufficient, excessive, or unsuitable. Step e: If it is determined that the initial preset water volume is insufficient, the incremental water volume to be replenished is determined based on the ratio of the data deviation difference to the historical change rate, and the intelligent limited water addition unit is controlled to continue adding water to the multi-slag and multi-bone raw materials in the heating and softening process according to the incremental water volume to be replenished; if it is determined that the initial preset water volume is excessive, the required settling time is determined based on the difference between the data deviation difference and the boundary of the stable interval, and the intelligent limited water addition unit is controlled to pause water addition and maintain the current settling time; if it is determined that the initial preset water volume is suitable, the intelligent limited water addition unit is controlled to continue adding water to the multi-slag and multi-bone raw materials in the heating and softening process at the current water addition rate; Repeat steps a to e until the deviation between the rheological characteristics and solid content data of the initial preset water volume and the current pumpable characteristics adaptation range is less than the preset deviation threshold, complete the feedback correction, and determine the final water volume to be added.

The continuous processing method for processing raw materials with multiple slag and aggregate content as described in claim 8, characterized in that, The rheological properties and solid content data of the multi-slag and multi-bone raw materials during the heating and softening process of adding an initial preset water volume are filtered for abnormal data according to a preset abnormal data filtering rule, to obtain the rheological properties and solid content data of the added initial preset water volume, including: Based on the effective data sequence, the mean and standard deviation of the rheological properties of the multi-slag and multi-bone raw materials during the heating and softening process are obtained, as well as the mean and standard deviation of the solid content data, which serve as the benchmark for judging abnormal data. The single set of rheological property data of the multi-slag and multi-bone raw materials collected during the heating and softening process of adding the initial preset water volume is compared with a first preset statistical threshold range determined by the mean of the rheological property data and the standard deviation of the rheological property data. If the single set of rheological property data exceeds the first preset statistical threshold range, it is marked as rheological property abnormal data. The single set of solid content data of the multi-slag and multi-bone raw materials collected during the heating and softening process of adding the initial preset water volume is compared with the second preset statistical threshold range determined by the mean of the solid content data and the standard deviation of the solid content data. If the single set of solid content data exceeds the second preset statistical threshold range, it is marked as solid content abnormal data. The trend of the marked rheological property anomaly data is compared with the trend of the two adjacent sets of valid rheological property data before and after the anomaly data. The trend of the solid content anomaly data is also compared with the trend of the two adjacent sets of valid solid content data before and after the anomaly data. If the direction of change of the rheological property anomaly data is opposite to the trend of change of the two adjacent sets of valid rheological property data before and after the anomaly data, and the magnitude of change exceeds the first preset magnitude threshold corresponding to the magnitude of change of the two adjacent sets of valid rheological property data before and after the anomaly data, then it is determined to be rheological property anomaly data to be removed. If the direction of change of the solid content anomaly data is opposite to the trend of change of the two adjacent sets of valid solid content data before and after the anomaly data, and the magnitude of change exceeds the second preset magnitude threshold corresponding to the magnitude of change of the two adjacent sets of valid solid content data before and after the anomaly data, then it is determined to be solid content anomaly data to be removed. Unlabeled rheological property data and solid content data, as well as rheological property abnormal data and solid content abnormal data that do not need to be removed after comparison, are retained and integrated to form the rheological property and solid content data with the added initial preset water volume.

The continuous processing method for processing raw materials with multiple slag and aggregate content as described in claim 8, characterized in that, The step of comparing the rheological characteristics and solids content data of the added initial preset water volume with the current pumpable characteristic adaptation range to obtain the data deviation difference, and combining the historical trend analysis results to determine whether the initial preset water volume is insufficient, excessive, or unsuitable, includes: The rheological characteristic data of the added initial preset water volume is compared with the rheological characteristic threshold range in the current pumpable characteristic adaptation interval to obtain the rheological characteristic deviation difference; the solid content data of the added initial preset water volume is compared with the solid content threshold range in the current pumpable characteristic adaptation interval to obtain the solid content data deviation difference. Based on the historical rate of change in the historical trend analysis results, determine whether the direction of change of the rheological property deviation difference and the solid content data deviation difference is consistent with the trend of the historical rate of change; Based on the stable interval boundary in the historical trend analysis results, determine whether the deviation difference of the rheological properties and the deviation difference of the solid content data exceed the allowable deviation range corresponding to the stable interval boundary; If the deviation difference of the rheological properties and the deviation difference of the solid content data are both less than the allowable deviation corresponding to the current pumpable characteristic adaptation range, and the direction of change is the same as the trend of the historical change rate and does not exceed the allowable deviation range corresponding to the boundary of the stable range, then the initial preset water volume adaptation is determined. If the deviation difference of the rheological properties and the deviation difference of the solid content data are both greater than the allowable deviation corresponding to the current pumpable characteristic adaptation range, and the direction of change is the same as the trend of the historical change rate and does not exceed the allowable deviation range corresponding to the boundary of the stable range, then it is determined that the initial preset water volume is insufficient. If the deviation difference of the rheological properties and the deviation difference of the solid content data both exceed the allowable deviation range corresponding to the boundary of the stable interval, and the direction of change is opposite to the trend of the historical change rate, then it is determined that the initial preset water volume is excessive.
