Description

Technical Field

[0001] This invention relates to the field of conveying machinery and equipment technology, specifically to a cleaning device for preventing material breakage and spillage on a plate chain conveyor in a pulping workshop. Background Technology

[0002] Plate chain conveyors are widely used in the pulp and paper industry to transport various pulping raw materials, such as wood chips and waste paper pulp, due to their robust structure and large conveying capacity.

[0003] In the actual production scenario of a pulping workshop, the characteristics of the conveyed materials are dynamically changing. A common scenario is that, in order to adjust product formulations or process different batches of raw materials, conveyors need to transport materials with high moisture content, fine fibers, and strong viscosity, such as high-proportion recycled pulp (waste paper pulp) or damp raw materials. Under these conditions, the following technical problems become apparent:

[0004] First, existing cleaning devices suffer from incomplete cleaning. When conveying highly viscous materials, a large amount of fine debris and fibers stubbornly adhere to the surface, seams, and hinges of the chain plate. Current common cleaning methods, such as simple mechanical scrapers, are insufficient to effectively remove this sticky material, only removing some large pieces; while simple air purging lacks sufficient kinetic energy to remove sticky, wet debris. This causes residual debris to accumulate during the chain plate's return stroke, being carried into drive sprockets or idlers, accelerating equipment wear, affecting the stable operation of the conveyor, and even detaching after drying, causing secondary pollution to the workshop environment.

[0005] Secondly, the methods for recovering spilled debris are inefficient and prone to creating new problems. Traditionally, debris cleaned from the conveyor belt usually falls into a simple collection trough or onto the ground. For highly viscous wet debris, its poor flowability makes it easy to accumulate and clump in the collection trough, preventing smooth flow and recovery by gravity. This ultimately requires a large amount of manpower for regular cleaning, leading to production interruptions and increased labor intensity. Although some solutions use spray water for rinsing, this is usually a direct-flow rinsing method, which not only consumes a large amount of fresh water resources and increases production costs, but also generates wastewater containing a large amount of fibrous impurities, which, if discharged directly, will burden the environment.

[0006] Finally, existing cleaning devices are insufficiently adaptable to changing operating conditions. The types and states of materials transported in pulping workshops (such as dry / wet, virgin / reclaimed pulp) change frequently, and their adhesion characteristics vary significantly accordingly. Existing cleaning devices typically use fixed operating parameters, such as fixed scraping force, fixed purging pressure, or fixed flushing water volume. This design leads to a waste of energy and water resources when handling low-adhesion materials; while its cleaning capacity is insufficient when dealing with high-adhesion materials, failing to guarantee cleaning effectiveness. The system lacks the ability to dynamically adjust the cleaning intensity based on changes in the material's adhesion characteristics.

[0007] Therefore, how to provide a plate chain conveyor cleaning device that can thoroughly clean up spilled debris with different adhesion characteristics, achieve efficient and automatic material recycling, and adaptively adjust to balance environmental protection and energy saving is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a cleaning device for preventing spilled material from a plate chain conveyor in a pulping workshop. This device solves the problems of incomplete cleaning, difficult recycling, easy clogging, and limited cleaning methods that exist in existing plate chain conveyors for pulping workshops when cleaning spilled material with strong viscosity.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing material spillage and cleaning of a plate chain conveyor in a pulping workshop, comprising: a conveyor body, a drive wheel, and a controller. A baffle is installed on the top of the conveyor body. A cleaning mechanism is provided at the bottom of the conveyor body, and a recycling mechanism is also provided at the bottom of the conveyor body.

[0010] The controller integrates a collaborative control system. This system processes the data collected by the detection module through a control module, generates a start command, and inputs the start command to the function execution module.

[0011] The cleaning mechanism includes a drive assembly and a blowing assembly. The drive assembly includes a motor, the output end of which is fixedly connected to the outside of the drive wheel. A second gear is fixedly connected to the outer periphery of the drive wheel. Supports are fixedly connected to both sides of the conveyor body, and a roller brush is rotatably connected between the two supports. A first gear is fixedly connected to one end of the roller brush. A chain is fitted around both the first and second gears.

[0012] Preferably, the blowing assembly includes two brackets, which are fixedly connected to both sides of the conveyor body, and air jet rods are fixedly connected to the bottom of the two brackets.

[0013] Preferably, the recycling mechanism includes a flushing assembly and a receiving assembly. The flushing assembly includes two robotic arms, both of which are rotatably connected to the outside of the conveyor body. Water spray bars are fixedly connected to the bottom of the two robotic arms, and several nozzles are fixedly connected to the outside of the water spray bars.

[0014] Preferably, the receiving component includes two robotic arms, both of which are fixedly connected to the outside of the conveyor body, and a receiving trough is rotatably connected between the two robotic arms.

[0015] In one specific embodiment, the detection module includes a high-speed camera, which is fixedly connected to the outside of the spray bar. The high-speed camera is used to acquire image data of debris adhering to the surface of the conveyor chain plates in real time, and transmit the acquired image data to the control module.

[0016] The control module analyzes the image data to determine whether there is any debris adhering to the surface of the chain plate and the amount of such debris. When debris is detected, the control module sends a start command to the function execution module, driving the cleaning mechanism and the recycling mechanism to operate.

[0017] Furthermore, the control module adjusts the output power of the motor based on the amount of adhesive material collected by the high-speed camera.

[0018] When the amount of adhesive material is at a preset low threshold, the motor is controlled to operate at low power, driving the roller brush to rotate at low speed.

[0019] When the amount of adhering material reaches a preset high threshold, the motor is controlled to operate at high power, driving the roller brush to rotate at high speed to enhance the scraping effect on stubborn adhering debris.

[0020] Preferably, the roller brush is made of steel wire, and the rotation direction of the roller brush is opposite to the running direction of the chain plate at the contact point with the conveyor body. This structure is used to physically scrape away stubborn debris adhering to the surface of the chain plate.

[0021] The air jet bar is positioned behind the roller brush along the chain plate's running direction. The air jet bar has several air outlets evenly distributed along its length, covering the entire width of the chain plate. This structure is used for secondary blowing away fine debris remaining after the roller brush cleaning.

[0022] Preferably, the receiving trough has a sloping structure, with its lowest end facing the pulper inlet. The nozzles are evenly distributed along the length of the spray bar, and the spray direction of the nozzles is towards the inner wall of the receiving trough. The sprayed water acts directly on the crushed material in the receiving trough, preventing the crushed material from drying and clumping, and uses the water flow to transport the crushed material to the pulper.

[0023] In one specific embodiment, the collaborative control system of the controller further includes: when the receiving trough detects that the amount of broken material accumulation reaches a preset threshold, the control module sends an adjustment command to the robotic arm to drive the robotic arm to increase the tilt angle of the receiving trough, accelerate the flow speed of broken material, and prevent the broken material from accumulating in the trough.

[0024] Preferably, the control module establishes signal connections with both the jet bar and the nozzle. The control module has a built-in database of operating condition adaptation parameters, which can dynamically adjust the jet air pressure of the jet bar, as well as the water flow rate and spray range of the nozzle, according to the operating conditions of the pulping workshop at different times, thus forming an adaptive and dynamic cleaning system.

[0025] When the amount of recycled pulp fiber is large or the raw material is highly damp, the control module calls the high adhesion condition parameters, increases the jet pressure of the jet bar, increases the water flow of the nozzle, and expands the jet range;

[0026] When the amount of recycled pulp fiber is small or the moisture content of the raw material is low, the low adhesion working condition parameters are called and the corresponding parameters are lowered to achieve adaptive cleaning under working conditions.

[0027] This invention provides a device for preventing material spillage and cleaning on a plate chain conveyor in a pulping workshop. It has the following beneficial effects:

[0028] 1. This invention achieves a more thorough cleaning effect by employing a two-stage synergistic cleaning structure of mechanical brushing and gas blowing. First, a steel wire roller brush rotates in the opposite direction to physically scrape away large or wet debris stubbornly adhering to the chain plate. Then, an air jet bar located at the rear blows away the fine powder remaining after the roller brush cleaning. This progressive cleaning combination effectively overcomes the limitations of single cleaning methods and can simultaneously handle debris of different shapes and adhesion strengths.

[0029] 2. This invention achieves efficient recycling and resource conservation of crushed materials by adopting an integrated design of inclined flow guidance and real-time flushing, as well as a spray water circulation system. The receiving trough of this invention utilizes an inclined structure to achieve gravity flow guidance of crushed materials, while the real-time spray water from the nozzles not only prevents the crushed materials from drying and clumping, but also helps to push the crushed materials into the pulper, avoiding manual trough cleaning.

[0030] 3. This invention enhances the device's adaptability to different working conditions by constructing an adaptive and dynamic cleaning system. The controller of this invention can dynamically access data from the working condition adaptation parameter library based on the adhesion of the debris (such as the amount of recycled pulp and the moisture level of the raw materials), automatically adjusting the airflow pressure of the jet bar, the water flow rate and range of the nozzles, and the rotation speed of the roller brush. This allows the device to allocate energy and water resources as needed while ensuring cleaning effectiveness, avoiding waste under low adhesion conditions and insufficient cleaning under high adhesion conditions.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] See attached document Figure 1 and attached Figure 2 The present invention provides a device for preventing material spillage and cleaning of a plate chain conveyor in a pulping workshop, comprising: a conveyor body 1, a controller 2, and a baffle 3.

[0041] The conveyor body 1 is a plate chain conveyor. Baffles 3 are installed on the top of the conveyor body 1, and are located on both sides or above the chain running path to prevent pulping materials from splashing or spilling outwards during the conveying process.

[0042] It also includes a cleaning mechanism located at the bottom of the conveyor body 1, and a recycling mechanism also located at the bottom of the conveyor body 1. Both the cleaning mechanism and the recycling mechanism are located on the return stroke side of the chain plate of the conveyor body 1.

[0043] Controller 2 is used to coordinate the operation of the cleaning and recycling mechanisms.

[0044] Controller 2 integrates a collaborative control system. The collaborative control system includes: a detection module a, a control module b, and a function execution module c. Control module b establishes signal connections with both detection module a and function execution module c.

[0045] The control module b processes the data collected by the detection module a to generate a start command, and then inputs the start command to the function execution module c.

[0046] This control logic can be described as follows:

[0047] S start =f control (D detect );

[0048] Among them, D detect For the real-time data collected by detection module a; f control For the preset control logic or judgment algorithm built into control module b; S start For control module b according to f control For D detect The generated startup command after processing. Function execution module c receives the startup command S. start Then, the cleaning and recycling mechanisms are put into operation.

[0049] See attached document Figure 3 and attached Figure 4 The cleaning mechanism is located at the bottom of the conveyor body 1, specifically on the return stroke side of the chain plate. The cleaning mechanism includes a drive assembly and a blowing assembly.

[0050] In one specific embodiment, the drive assembly includes a motor 6, the output end of which is fixedly connected to the outside of a drive wheel 17. A gear 12 is fixedly connected to the outer periphery of the drive wheel 17. Supports 18 are fixedly connected to both sides of the bottom of the conveyor body 1, and a roller brush 8 is rotatably connected between the two supports 18. A gear 11 is fixedly connected to one end of the roller brush 8.

[0051] A chain 10 is fitted around gear 11 and gear 2 12. This structure forms a power transmission path: after the motor 6 starts, its power is transmitted to gear 2 12 through the drive wheel 17. Gear 2 12 drives gear 11 to rotate through the chain 10, and gear 11 in turn drives the roller brush 8 to rotate.

[0052] To achieve physical scraping of stubbornly adhered debris, the roller brush 8 is preferably made of steel wire to provide sufficient mechanical rigidity. Furthermore, the rotation direction of the roller brush 8 is set opposite to the running direction of the chain plate of the conveyor body 1 at its contact point. This reverse rotational motion generates mechanical shearing and scraping forces between the roller brush 8 and the chain plate surface, used to peel off the debris adhering to the chain plate surface.

[0053] The blowing assembly includes two brackets 15, which are fixedly connected to both sides of the conveyor body 1. Air jet rods 7 are fixedly connected to the bottom of the two brackets 15.

[0054] To achieve progressive cleaning, the air jet bar 7 is positioned behind the roller brush 8 along the chain plate's running direction. The air jet bar 7 has several air outlets, such as flat nozzles 16, evenly distributed along its length. The distribution of these air outlets ensures that compressed air can cover the entire width of the chain plate.

[0055] In this embodiment, the cleaning mechanism operates as follows: When the chain plate of the conveyor body 1 returns from the bottom, it first passes through the roller brush 8. The wire roller brush 8 performs a first-stage physical scraping of the debris adhering to the surface of the chain plate by rotating in the opposite direction. Subsequently, the chain plate continues to run to the position of the air jet bar 7, where the compressed air ejected by the air jet bar 7 performs a second-stage gas purging of any fine debris or powder that may remain after being scraped by the roller brush 8.

[0056] This dual-stage synergistic cleaning structure combines the ability of physical scraping to handle stubborn adhesives with the ability of gas purging to clean fine residues, creating a progressive cleaning effect that can adapt to the cleaning needs of debris with different adhesion strengths.

[0057] See attached document Figure 5 The recycling mechanism is also located at the bottom of the conveyor body 1, physically below the cleaning mechanism, and is used to receive and process the debris removed from the chain plate by the cleaning mechanism. The recycling mechanism includes a receiving component and a flushing component.

[0058] In one specific embodiment, the receiving component includes two robotic arms 4 and a receiving trough 5. Both robotic arms 4 are fixedly connected to the outside of the conveyor body 1, and the receiving trough 5 is rotatably connected between the two robotic arms 4 and supported directly below the cleaning mechanism.

[0059] The receiving trough 5 is designed as a sloping structure, with its lowest point facing the feed inlet of the pulper during installation. This structure utilizes gravity to naturally guide the crushed material falling into the trough. The component of the force F acting on the crushed material on the slope, downwards along the slope, is... slide It can be represented as:

[0060] F slide =G·sin(θ)=m·g·sin(θ);

[0061] Where G is the gravity acting on the crushed material; m is the mass of the crushed material; g is the acceleration due to gravity; and θ is the inclination angle of the receiving trough 5. This design utilizes the component of gravity to achieve passive guiding and conveying of the crushed material.

[0062] The flushing assembly includes two robotic arms 13 and a water spray bar 9. Both robotic arms 13 are rotatably connected to the outside of the conveyor body 1 and support the water spray bar 9, positioning it above the receiving trough 5. Several nozzles 16 are fixedly connected to the outside of the water spray bar 9, evenly distributed along its length.

[0063] The spray direction of nozzle 16 is set towards the inner wall of the receiving trough 5. This structure is used to achieve a real-time flushing function. When the crushed material falls into the receiving trough 5, the water flow sprayed from nozzle 16 acts directly on the crushed material and the inner wall of the trough. This design has a dual function: firstly, the sprayed water can prevent the crushed material from drying and clumping in the trough, thus avoiding blockage of the flow path; secondly, the momentum generated by the water flow can help propel the crushed material along the slope towards the pulper feed inlet.

[0064] The sloping material receiving trough 5, together with the water spray bar 9 and nozzle 16, forms an integrated design. This design combines gravity guidance with water flushing, achieving efficient recycling of crushed materials and self-cleaning of the material receiving trough 5.

[0065] See attached document Figure 6 and attached Figure 7 In this embodiment of the invention, the collaborative control system is integrated within the controller 2 to automate and dynamically adjust the entire cleaning and recycling process. The collaborative control system includes a detection module a, a control module b, and a function execution module c.

[0066] In one specific embodiment, the detection module a includes a high-speed camera 14 disposed outside the spray bar 9. The high-speed camera 14 is positioned to acquire real-time image data of the return travel surface of the conveyor body 1's chain plate, and transmits this image data to D. detect Transmitted to control module b.

[0067] Control module b receives image data D detect Then, it is analyzed and processed, for example, by using image recognition algorithms to determine whether there is any debris P adhering to the surface of the chain plate. debris and the amount or area of ​​the adhered material Qdebris When control module b determines that there is debris adhering to it (i.e., P... debris If the value is True, then a start command S is sent to the function execution module c. start After receiving the instruction, the function execution module c drives the cleaning mechanism (such as motor 6 and jet bar 7) and the recovery mechanism (such as water spray bar 9) to start operation.

[0068] Furthermore, control module b performs dynamic cleaning intensity adjustment. Control module b uses the amount of adherent material Q collected and analyzed by high-speed camera 14 as the basis for this adjustment. debris Compare it with the preset low threshold T low and high threshold T high Compare them.

[0069] When T low ≤Q debris <T high At that time, control module b determines that the adhesion condition is low and sends a command to function execution module c to control motor 6 to operate at low power P. low The operation drives the roller brush 8 to rotate at a low speed.

[0070] When Q debris ≥T high At that time, control module b determines that it is a high adhesion condition and sends a command to control motor 6 to operate at high power P. high The operation drives the roller brush 8 to rotate at high speed to enhance the scraping effect on stubbornly adhered debris.

[0071] In a preferred embodiment, the collaborative control system also dynamically adjusts the flow rate of the receiving trough 5. The detection module a may further include an accumulation detection sensor (e.g., a weight sensor or optical sensor) mounted on the receiving trough 5 or its supporting structure (such as the robotic arm 4) for real-time monitoring of the accumulation amount M of the broken material within the trough. accum Control module b will M accum With the preset stacking threshold T accum Compare them.

[0072] When M accum ≥T accum At that time, control module b sends adjustment command S to function execution module c. adjust_angle The function execution module c drives the actuator (e.g., servo motor) of the robotic arm 4, increasing the tilt angle θ of the receiving trough 5. This increase in tilt angle θ leads to an increase in the gravitational component F acting on the scrap material. slide This increases the flow rate of the crushed material, thereby preventing accumulation and blockage.

[0073] In another specific embodiment, control module b establishes signal connections with the air source control valve of jet bar 7 and the water source control valve of nozzle 16, respectively. Control module b has a built-in operating condition adaptation parameter library. This parameter library stores the optimal cleaning parameters (including jet airflow pressure P) corresponding to different pulping workshop operating conditions (e.g., high / low recycled pulp fiber content, high / low raw material moisture content). air Water flow rate V water With spray range R spray ).

[0074] When operating conditions change (e.g., manually input via the user interface or automatically detected by other sensors), control module b retrieves the corresponding parameter set from the parameter library. For example, when the operating condition involves a high amount of recycled pulp fiber or a high degree of moisture in the raw material, indicating strong adhesion of the scrap, control module b retrieves the parameters for the high adhesion operating condition. The instruction execution module c increases the jet pressure of the jet rod 7, increases the water flow of the nozzle 16, and expands the jet range.

[0075] Conversely, when the operating conditions are characterized by low recycled pulp fiber content or low raw material moisture content, the low adhesion operating parameters should be selected. Lower the corresponding parameters. This dynamic adjustment system ensures that the device maintains good cleaning and recycling performance under different operating conditions.

[0076] Working Principle: During the pulping process, when the pulping raw materials are conveyed by the plate chain conveyor body 1, to prevent material splashing during operation, the baffle 3 installed on the top of the conveyor body 1 blocks the sides or top of the material running path. After the conveying is completed, the chain plate of the conveyor body 1 enters the return stroke. At this time, the high-speed camera 14 installed outside the water spray bar 9 and as part of the detection module a will continuously photograph the bottom surface of the returning chain plate and transmit the real-time image data including the situation of the debris adhering to the chain plate surface to the controller 2. After receiving the image data, the control module b inside the controller 2 immediately analyzes the information such as the coverage area and thickness of the debris through the built-in image recognition algorithm, so as to accurately determine the current contamination level of the chain plate. Based on the contamination level and the preset working condition adaptation parameter library in the system, such as whether the current conveyed pulp is high viscosity recycled pulp or low viscosity virgin pulp, a set of coordinated control instructions including cleaning intensity and recycling strategy is generated. Then, the instructions are sent to the function execution module c. After receiving the instructions, the function execution module c immediately starts the entire cleaning and recycling process.

[0077] First, the motor 6 in the drive cleaning mechanism starts to run. The power of the motor 6 is transmitted to the gear 12 through the drive wheel 17 connected to its output end. The gear 12 then drives the gear 11 fixed to the roller brush 8 to rotate through the externally sleeved chain 10. This drives the steel wire roller brush 8, which is stably supported by two brackets 18, to rotate in the opposite direction to the forward direction of the chain plate. Its speed is dynamically adjusted by the control module b according to the previously determined pollution level. Through this powerful reverse mechanical scraping, large or sticky stubborn debris is peeled off from the surface of the chain plate, completing the first stage of physical cleaning.

[0078] Next, as the chain plate continues to run to the area below the jet bar 7, which is fixed behind the roller brush 8 by two brackets 15, the function execution module c controls the air source solenoid valve connected to the jet bar 7 to open according to the instruction, so that compressed air with a specific pressure is ejected from the air outlet on the jet bar 7, forming an air curtain covering the entire width of the chain plate. This performs a second-stage non-contact blowing to clean any small debris or powder that may remain after the first-stage scraping, thus achieving a thorough cleaning of the chain plate.

[0079] Throughout the entire cleaning process, all scraped and blown debris falls vertically under gravity and accurately enters the sloping receiving trough 5, which is supported by two robotic arms 4 rotating below the cleaning mechanism. Simultaneously, the function execution module c drives the recycling mechanism to operate, controlling multiple nozzles 16 on the water spray bar 9, supported by the two robotic arms 13, to spray water onto the inner wall of the receiving trough 5. The volume of this water flow is intelligently adjusted by the control module b based on the characteristics of the debris, such as its moisture content. The flushing effect of the water flow effectively prevents the wet debris from accumulating and caking in the trough. It can also provide additional kinetic energy to assist and accelerate the sliding of the crushed material along the inclined surface of the receiving trough 5 towards the feed inlet of the pulper, achieving efficient flow guidance and recycling. Furthermore, during the recycling process, if the controller 2 senses that the flow rate of the material in the receiving trough 5 is too slow and there is a risk of blockage, the control module b will immediately instruct the function execution module c to drive the robotic arm 4 to move, dynamically increasing the tilt angle of the receiving trough 5, and using the increase in the gravity component to improve the conveying efficiency. Thus, without human intervention, the entire closed-loop operation from pollution detection, dynamic grading and cleaning to anti-blockage recycling is completed automatically, efficiently, and with water and electricity savings.

A device for preventing material spillage and cleaning on a plate chain conveyor in a pulping workshop according to claim 3, characterized in that, The control module establishes signal connections with the jet rod (7) and the nozzle (16) respectively. The control module has a built-in working condition adaptation parameter library, which can dynamically adjust the jet air pressure of the jet rod (7) and the water flow rate and jet range of the nozzle (16) according to the working conditions of different time periods in the pulping workshop. When the amount of recycled pulp fiber is large or the raw material is highly damp, the control module calls the high adhesion working condition parameters, increases the spray pressure of the jet bar (7), increases the water flow of the nozzle (16) and expands the spray range; When the amount of recycled pulp fiber is small or the moisture content of the raw material is low, the low adhesion working condition parameters are called and the corresponding parameters are lowered to achieve adaptive cleaning under working conditions.
