[0058] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0059] The following is combined Figures 1-4 Describe the structure and working principle of this utility model.

[0060] Reference Figure 1 The waste residue treatment device provided by this utility model includes a raw material storage component 100, an automatic batching component 200, a multi-stage grinding component 300, a calcination component 400, a finished product collection component 500, and a control system 600. The system includes multiple raw material storage components 100 arranged in parallel, used for storing materials; automatic batching components 200 are connected to each raw material storage component 100 in a one-to-one correspondence, used to obtain a predetermined weight of material from the corresponding raw material storage component 100; multi-stage grinding components 300 are connected to each automatic batching component 200, used to mix and grind the materials obtained by each automatic batching component 200; calcination components 400 are connected to the multi-stage grinding components 300, used to calcine the material ground by the multi-stage grinding components 300; finished product collection components 500 are connected to the calcination components 400, used to store the calcined material; and a control system 600 is signal-connected to the raw material storage components 100 and the automatic batching components 200, used to control the predetermined weight of material obtained by the automatic batching components 200.

[0061] Specifically, the raw material storage components 100 are equipped with multiple units, each storing different materials. The control system 600 sends instructions to each raw material storage component 100 according to a preset ratio, causing it to transport a predetermined weight of material to the automatic batching component 200. The automatic batching component 200 uses a weight sensor to provide real-time feedback of material weight data to the control system 600, achieving closed-loop control of the raw material ratio and solving the problem of low accuracy in traditional manual batching. The material weighed by the automatic batching component 200 enters the multi-stage grinding component 300 for mixing and grinding. This component adopts a stepped grinding process, using coarse and fine grinding to achieve a predetermined fineness for the waste residue particles. The ground mixture is then transported to the calcination component 400 for thermal activation treatment under a controllable temperature curve, releasing active components by breaking down the crystal structure of inert substances in the waste residue.

[0062] This invention achieves efficient pretreatment of waste residue through the synergistic action of a raw material storage component 100, an automatic batching component 200, a multi-stage grinding component 300, a calcination component 400, a finished product collection component 500, and a control system 600. The control system 600 provides fully automated control of the batching accuracy, grinding fineness, and calcination process, ensuring that each component in the waste residue participates in the reaction in the optimal ratio, resulting in a final cementitious material with higher mechanical properties and stability. The coordinated adjustment of process parameters between the multi-stage grinding component 300 and the calcination component 400 solves the problem of low cementitious material performance caused by insufficient activation of waste residue in traditional treatment devices.

[0063] Reference Figure 2 In some embodiments of this utility model, the raw material storage assembly 100 includes a storage bin 110, a feed controller 120, and a discharge controller 140. The feed controller 120 is located at the top of the storage bin 110 and is used to control the entry of materials; the discharge controller 140 is located at the bottom of the storage bin 110 and is connected to the control system 600 by signal, and is used to control the output of materials.

[0064] Specifically, the storage silo 110 can be made of carbon steel or stainless steel to withstand the corrosive and abrasive properties of the waste residue. The feed controller 120 is fixed to the top of the storage silo 110, and can be fixed by flange connection or welding to ensure sealing and prevent dust leakage. The feed controller 120 can be equipped with a gate valve or rotary valve for precise control of the material inflow rate. The discharge controller 140 is fixed to the bottom of the storage silo 110 and fixed by bolts or clamps for easy disassembly and maintenance. The discharge controller 140 can be equipped with a screw conveyor or pneumatic discharge valve, whose drive motor or cylinder is connected to the control system 600 to achieve quantitative discharge.

[0065] This embodiment achieves precise storage and conveying of waste residue through the coordinated action of storage bin 110, feed controller 120, and discharge controller 140. Feed controller 120 controls material entry from the top of storage bin 110, preventing overfilling and reducing dust. Discharge controller 140 receives instructions from control system 600 at the bottom of storage bin 110 and outputs material at a set rate, ensuring the proportioning accuracy of subsequent automatic batching components 200. The sealed structure of storage bin 110 reduces the risk of material moisture or contamination, while the precise adjustment capability of discharge controller 140 prevents material blockage or flow fluctuations. This structure improves the stability and automation of the waste residue pretreatment process, reduces manual intervention, and ensures the consistency of raw materials for subsequent processes.

[0066] Reference Figure 2 In some embodiments of this utility model, the storage bin 110 includes a support frame 111, a tilting bucket 112, and a storage box 113. A feed controller 120 is located at the top of the storage box 113; the tilting bucket 112 is connected to the bottom of the storage box 113, and the diameter of the tilting bucket 112 gradually decreases from top to bottom. A discharge controller 140 is located at the bottom of the tilting bucket 112; the support frame 111 is located on either the support frame 111 or the tilting bucket 112.

[0067] Specifically, the support frame 111 can adopt a welded steel frame structure or a bolted assembly bracket, with anchor bolts at its bottom to fix it to the foundation to enhance overall stability. The storage tank 113 is fixedly mounted on the upper part of the support frame 111, and can be connected by welding or high-strength bolts to ensure load-bearing capacity. The top of the storage tank 113 has a flange interface, and the feed controller 120 is fixedly connected by flange bolts to form a sealed feed channel. The bucket 112 is welded or flanged to the bottom end of the storage tank 113, and its conical inner wall can be lined with wear-resistant plates to extend its service life. The bottom end of the bucket 112 has a flange interface, and the discharge controller 140 is fixedly connected by flanges or quick-release clamps for easy disassembly and maintenance. In the above structure, the columns of the support frame 111 can be equipped with reinforcing ribs to improve the support strength for the storage tank 113 and the bucket 112.

[0068] This embodiment achieves stable storage and controllable output of waste residue through the structural cooperation of the support frame 111, storage tank 113, and tilting bucket 112. The support frame 111 provides rigid support for the entire storage bin 110, ensuring the structural stability of the storage tank 113 under full load conditions. The upright design of the storage tank 113 increases the effective volume, while the tapered structure of the tilting bucket 112 guides the material to fall naturally, avoiding accumulation and blockage. The above structure reduces the need for mechanical intervention during the material discharge process, while the geometry of the tilting bucket 112 effectively prevents material bridging, ensuring that the discharge controller 140 can accurately control the discharge volume.

[0069] Reference Figure 2In some embodiments of this utility model, the bucket 112 is equipped with a vibrator 130. Specifically, the vibrator 130 can be fixedly installed at the middle of the outer side wall of the bucket 112, and fastened with high-strength bolts and anti-loosening washers. The mounting base of the vibrator 130 can be welded to the outer wall of the bucket 112 with a reinforcing plate to improve vibration transmission efficiency and prevent local deformation. The vibrator 130 can be an electric or pneumatic excitation source, and its power cord or air pipe passes through a pre-set wiring hole in the side wall of the bucket 112 through a waterproof connector. In the above structure, the installation position of the vibrator 130 should avoid the connection flange between the bucket 112 and the storage box 113 and the discharge controller 140 to avoid the impact of vibration on the sealing structure. The excitation direction of the vibrator 130 can be set to tangential vibration perpendicular to the conical surface of the bucket 112 to promote material flow at the optimal angle.

[0070] This embodiment effectively solves the blockage problem caused by material adhesion and arching inside the bucket 112 by adding a vibrator 130. When the discharge controller 140 is turned on, the vibrator 130 starts synchronously to generate high-frequency micro-amplitude vibration, causing relative movement between the inner wall of the bucket 112 and the material, thus breaking the static accumulation state of the material. The vibration reduces the internal friction of the material, enhances its fluidity, and ensures that the material slides evenly down the conical surface of the bucket 112 to the discharge controller 140. The above structure significantly improves the adaptability to high-humidity and high-viscosity waste residue, reduces the need for manual tapping to clear blockages, and avoids equipment damage caused by mechanical clearing. The linkage control between the vibrator 130 and the discharge controller 140 ensures that the vibration only operates during the unloading process, reducing energy consumption and mechanical wear.

[0071] In some embodiments of this utility model, the automatic batching component 200 includes a belt conveyor (not shown in the figure) and a weighing and metering component (not shown in the figure). One end of the belt conveyor is connected to the discharge controller 140, and the other end is connected to the multi-stage grinding component 300; the weighing and metering component is located on the belt conveyor and is signal-connected to the control system 600. The weighing and metering component is used to weigh the material on the belt conveyor. Multiple weighing and metering components can be set, and the average value is taken, thereby reducing errors.

[0072] Specifically, the belt conveyor component can adopt a trough-type idler assembly structure, with its frame fixed to the foundation by anchor bolts. Adjustable baffles are provided on both sides of the conveyor belt to prevent material spillage. The feed end of the belt conveyor component has a guide chute, which is sealed to the outlet of the discharge controller 140 via flange bolts. The weighing and metering component includes a weighing bridge and weighing sensors. The weighing bridge is fixed to the crossbeam of the belt conveyor component's frame by high-strength bolts, and the weighing sensors are symmetrically arranged on both sides of the weighing bridge and connected to the control system 600 via shielded cables. In the above structure, the drive roller of the belt conveyor component can be equipped with a variable frequency motor, whose speed signal is fed back to the control system 600 to achieve conveying speed adjustment. The weighing area of ​​the weighing and metering component can be equipped with a cleaning device to keep the surface of the weighing bridge clean to ensure metering accuracy.

[0073] This embodiment achieves precise batching of waste residue through the cooperation of a belt conveyor and a weighing and metering component. When the discharge controller 140 is activated, the material falls onto the belt conveyor via a guide chute. The weight of the material on the conveyor belt surface is transferred to the weighing sensor via a weighing bridge. The weighing sensor collects the weight signal in real time and transmits it to the control system 600. The system obtains the cumulative conveying volume through integral calculation, and when the set value is reached, it controls the discharge controller 140 to shut down. In the above structure, the continuous conveying mode of the belt conveyor improves batching efficiency compared to batch weighing, and the closed-loop control of the weighing and metering component and the conveying speed ensures metering accuracy under different flow conditions. The sealed design of the belt conveyor reduces dust escape, while the dynamic weighing method avoids process interruptions caused by machine stoppage for weighing.

[0074] Reference Figure 3 In some embodiments of this utility model, the multi-stage grinding assembly 300 includes a support component 310, a feeding component 320, a primary grinding component 330, a secondary grinding component 340, and a sieving component 350. The support component 310 is used to support the feeding component 320, the primary grinding component 330, the secondary grinding component 340, and the screening component 350. The first end of the feeding component 320 is connected to the automatic batching component 200. The first end of the primary grinding component 330 is connected to the second end of the feeding component 320 and is used for primary grinding of the material. The first end of the secondary grinding component 340 is connected to the second end of the primary grinding component 330 and is used for secondary grinding of the material. The screening component 350 is connected to the second end of the secondary grinding component 340 and the first end of the primary grinding component 330. The screening component 350 is used to screen the material after grinding by the secondary grinding component 340. If the particle size of the material after grinding by the secondary grinding component 340 meets the preset size, the screening component 350 conveys the material to the calcining component 400. If the particle size of the material after grinding by the secondary grinding component 340 does not meet the preset size, the screening component 350 conveys the material to the primary grinding component 330.

[0075] Specifically, the support component 310 can be a welded steel frame with adjustable anchor bolts at the bottom for leveling. The feeding component 320 is fixedly connected to the upper crossbeam of the support component 310 via flange bolts, and its inlet is sealed to the outlet of the automatic batching assembly 200 via a flexible connection. The primary grinding component 330 is fixedly installed on the middle platform of the support component 310 via a shock-absorbing base, and its inlet is rigidly connected to the outlet of the feeding component 320 via a pipe. The secondary grinding component 340 is vertically installed below the primary grinding component 330 via high-strength bolts, with a flow guide transition chamber between the two. The screening component 350 is suspended and fixed to the top crossbeam of the support component 310 via an elastic hanger, and its inlet is connected to the outlet of the secondary grinding component 340 via a corrugated pipe. In the above structure, the connecting pipes between the various stages of equipment can be equipped with quick-release flanges for easy maintenance and cleaning. The drive motors of the primary grinding component 330 and the secondary grinding component 340 may be equipped with torque limiting couplings to prevent overload damage.

[0076] This embodiment achieves efficient grinding of waste residue through a multi-stage series grinding structure and a closed-loop screening system. The material is uniformly fed into the primary grinding unit 330 via the feeding component 320 for coarse crushing. The crushed material then falls directly into the secondary grinding unit 340 for fine grinding. The screening component 350 performs real-time classification of the final ground material. Qualified material is conveyed to the calcination component 400, while unqualified material is returned to the primary grinding unit 330 for reprocessing. The rigid frame of the support component 310 ensures the stability of each stage of the equipment during high-speed operation, and the shock-absorbing base effectively isolates the impact of grinding vibration on the overall structure. This structure achieves continuous, stepped grinding of the material, and the material circulation grinding mechanism ensures the consistency of the final product particle size. The closed-loop configuration of the screening component 350 and the grinding components significantly improves grinding efficiency and avoids energy waste caused by over-grinding.

[0077] Reference Figure 3 In some embodiments of this utility model, the support component 310 includes a base 311 and a support platform 312. The primary grinding component 330, the secondary grinding component 340, and the sieving component 350 are evenly distributed on the base 311; the support platform 312 is vertically disposed on the base 311, and the feeding component 320 is disposed on the top of the support platform 312. The specific positions of the primary grinding component 330, the secondary grinding component 340, and the sieving component 350 can be arranged according to actual needs.

[0078] Reference Figure 3 In some embodiments of this utility model, the feeding component 320 includes a pump 321 and a first conveying pipe 322. The pump 321 is mounted on the support platform 312 and one end is connected to the automatic batching component 200; one end of the first conveying pipe 322 is connected to the pump 321 and the other end is connected to the primary grinding component 330.

[0079] Specifically, the pump 321 is fixedly mounted on the mounting surface of the support platform 312 using high-strength bolts. The mounting surface can be equipped with shock-absorbing rubber pads to reduce vibration transmission. The inlet of the pump 321 is connected to the outlet of the automatic batching assembly 200 via a flange connection, and a sealing gasket can be installed between the flanges to prevent leakage. The first conveying pipe 322 is made of wear-resistant steel, with its inlet end connected to the outlet of the pump 321 via a quick-connect clamp, and its outlet end fixedly connected to the inlet of the primary grinding component 330 via flange bolts. In the above structure, the first conveying pipe 322 can be equipped with an adjustable support frame, which is bolted to the side beam of the support component 310, allowing for minor positional adjustments to the pipe. The drive motor of the pump 321 can be equipped with a waterproof junction box, and the power cord is connected to the control system 600 via a conduit.

[0080] This embodiment achieves stable material transport through the cooperation of a pump 321 and a first conveying pipe 322. The pump 321 continuously draws pre-mixed materials from the automatic batching assembly 200 and transports them at a constant flow rate to the primary grinding unit 330 via the first conveying pipe 322. The impeller design of the pump 321 ensures continuous material flow and avoids grinding load fluctuations caused by pulsed conveying. The smooth inner wall design of the first conveying pipe 322 reduces material transport resistance, and its rigid connection ensures the sealing of the conveying path. This structure achieves seamless connection between material batching and the grinding process. The stable conveying characteristics of the pump 321 ensure that the primary grinding unit 330 receives a continuous and uniform feed, laying the foundation for the stability of subsequent grinding processes. The closed conveying system effectively prevents dust escape and improves the working environment.

[0081] Reference Figure 3 In some embodiments of this utility model, the screening component 350 includes a screening machine 351, a second conveying pipe 352, and a return pipe 353. The screening machine 351 is mounted on the base 311 and has a feed inlet, a return outlet, and a discharge outlet, with the discharge outlet connected to the calcination assembly 400. One end of the second conveying pipe 352 is connected to the feed inlet, and the other end is connected to the outlet of the secondary grinding component 340. One end of the return pipe 353 is connected to the return outlet, and the other end is connected to the inlet of the primary grinding component 330.

[0082] Specifically, the screening machine 351 is fixedly installed on the mounting plane of the base 311 using anchor bolts. The mounting plane can be equipped with leveling shims to ensure the equipment is level. The inlet of the screening machine 351 is connected to the outlet of the second conveying pipe 352 via a flange, with a sealing rubber gasket between the flanges. The second conveying pipe 352 is made of wear-resistant alloy steel, and its inlet is connected to the outlet of the secondary grinding component 340 via a quick-connect clamp. An adjustable bracket is provided in the middle of the pipe and fixed to the column of the support component 310. The return pipe 353 adopts a U-shaped design, with its inlet connected to the return port of the screening machine 351 via flange bolts, and its outlet connected to the inlet of the primary grinding component 330 via a flexible connector. In the above structure, the outlet of the screening machine 351 can be equipped with a rotary discharge valve, connected to the drive motor via a coupling, to achieve quantitative discharge to the calcining component 400.

[0083] This embodiment achieves precise material classification and recycling through the synergistic action of the screening machine 351, the second conveying pipe 352, and the return pipe 353. Material processed by the secondary grinding component 340 enters the screening machine 351 through the second conveying pipe 352 for particle size classification. Qualified material is conveyed from the discharge port to the calcination component 400, while unqualified material is returned to the primary grinding component 330 for regrinding via the return pipe 353. The vibrating screen of the screening machine 351 generates a three-dimensional motion trajectory, ensuring that the material is fully dispersed and passes through the screen holes. This structure forms a closed-loop circulating grinding system, significantly improving grinding efficiency through automatic material classification and reflux mechanisms, and ensuring the consistency of the final product particle size. The optimized arrangement of the second conveying pipe 352 and the return pipe 353 enables powerless material conveying, reducing system energy consumption. The sealed connection design effectively prevents dust escape and improves the working environment.
