Description

Technical Field

[0001] This invention relates to the field of waste chip filtration technology, specifically to a composite chip conveyor filter water tank. Background Technology

[0002] In the fields of high-end equipment manufacturing and precision parts machining, the cleanliness of cutting fluid directly affects the surface quality, tool life, and machining accuracy. Meanwhile, increasingly stringent environmental regulations place higher demands on reducing industrial wastewater, controlling the liquid content of waste chips, and improving the recycling rate of cutting fluid. Composite chip removal and filtration devices, as a key interface connecting machining equipment and waste recycling systems, must efficiently separate and remove waste chips while maximizing the recovery and purification of cutting fluid to reduce hazardous waste generation and the frequency of cutting fluid replenishment. Currently, driven by both high-precision machining and environmental compliance, scraper-type chip removal devices are commonly used for composite chip removal and coarse filtration of waste chips in filter tanks. These devices typically involve fixing the scraper in place. Above the separation plate's transport path, the working edge of the scraper maintains a fixed mechanical gap or slight contact with the surface of the separation plate. Relying on the continuous movement of the separation plate, the processing waste attached to the plate surface is passively removed. However, during the process of cleaning the waste on the separation plate surface, the scraper only relies on a single constant force to complete the pushing operation. The scraper edge can only form a mechanical pushing effect on the surface of the waste, and cannot effectively break the adhesion interface formed between the waste and the plate surface. When the waste has multiple points of adhesion or local embedding on the plate surface, the constant thrust is difficult to effectively shear and peel off the root of the waste. After the cleaning operation, a thin layer of residual film is easily left on the plate surface, which greatly reduces the overall chip removal and cleaning efficiency and continuously affects the filtration and purification quality of the cutting fluid. Summary of the Invention

[0003] The purpose of this invention is to provide a composite chip conveyor filter water tank to address the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a composite chip conveyor filter water tank, comprising a filter box and a receiving box, wherein a conveyor chain plate for filtering waste chips is installed inside the filter box, a power roller for driving the conveyor chain plate is installed outside the filter box, and a chip removal assembly is installed inside the filter box, wherein the chip removal assembly is used to separate the waste chips outside the conveyor chain plate while disturbing the settled waste chips contained inside the filter box. The chip removal assembly includes a chip removal frame installed inside the filter box near the conveyor chain plate. A chip removal scraper is movably connected to the top of the chip removal frame, and the chip removal scraper maintains a slope fit with the conveyor chain plate. A chip removal port for discharging waste chips is opened between the chip removal frame and the filter box. A stabilizing frame is fixedly connected to the outside of the chip removal frame. A directional cylinder is fixedly connected to the side of the chip removal scraper near the chip removal port. A protruding post that cooperates with the directional cylinder is installed inside the stabilizing frame. The protruding post is used to strike the directional cylinder and slightly shake the chip removal scraper along the top of the chip removal frame. A cleaning assembly is provided inside the filter box, and the cleaning assembly is used to make the waste chips and waste liquid near the conveyor chain plate flow in multiple dimensions. The top of the connecting frame is provided with a micro-shaking component, which is used to drive the protruding column to move up and down while moving the chip removal scraper back and forth along the top of the chip removal frame. The filter box is equipped with an angle adjustment component, which is used to adjust the angle of the chip removal frame and chip removal scraper along one side of the conveyor chain plate.

[0005] Preferably, the micro-shaking component includes a centering groove formed at the bottom of the protruding post and a servo motor fixedly connected to one side of the stabilizing frame. A centering shaft is installed inside the centering groove, and a crank is movably sleeved on the outside of the centering shaft. A crank plate is fixedly connected to the output end of the servo motor, and the crank plate is located inside the stabilizing frame. A connecting post is installed at one end of the crank plate, and one end of the connecting post passes through the bottom end of the crank rod. The crank rod moves in multiple dimensions along one end of the crank plate through the connecting post.

[0006] Preferably, the top of the stabilizing frame is fixedly connected to two symmetrical displacement cylinders, and each displacement cylinder is equipped with a return spring inside. One end of the return spring extends to the outside of the displacement cylinder and is fixedly connected to the bottom of the chip discharge port.

[0007] Preferably, the cleaning assembly includes a rotating corner plate and a curved arm installed sequentially from left to right. A horizontal shaft column is installed at the end of the rotating corner plate near the curved arm. The top of the curved arm is movably sleeved on the outside of the horizontal shaft column. A power motor is fixedly connected to the outside of the filter box, and the output end of the power motor extends into the interior of the filter box and is fixedly connected to the bottom end of the curved arm. While the rotating corner plate moves eccentrically along the interior of the filter box by relying on the curved arm, it is used to alleviate the floating of waste debris and the disturbance of waste liquid around the conveyor chain plate.

[0008] Preferably, the filter box has several side columns movably connected inside, and each side column is movably sleeved with a side arm. The top of the side arm is movably sleeved with a concentric shaft column, and the end of the concentric shaft column away from the side arm is fixedly connected to one end of the rotating disk.

[0009] Preferably, the angle adjustment assembly includes a support frame fixedly connected to one side of the chip removal frame and a hinge plate movably connected inside the filter box, with the hinge plate located above the chip removal frame. The top of the support frame is fixedly connected to the bottom center of the hinge plate, and the chip removal frame moves along the inside of the filter box via the support frame. A linkage assembly is installed at the top of the filter box, and the linkage assembly is used to drive the hinge plate to move.

[0010] Preferably, the linkage assembly includes an electric push rod fixedly connected to the top of the filter box. The telescopic end of the electric push rod extends into the interior of the filter box and is fixedly connected to a guide plate. A first limiting shaft is installed at one end of the guide plate, and a second limiting shaft is installed on the side of the hinge plate away from the filter box. A vertical plate frame is connected between the second limiting shaft and the first limiting shaft.

[0011] Preferably, the top of the filter box is provided with a guide groove that communicates with its interior for the guide plate to move.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. The chip removal frame, chip removal scraper, and conveyor chain plate of this invention are configured such that the conveyor chain plate is driven by the power roller to rotate in a "U" shape inside the filter box. When the upper section of the conveyor chain plate carries the waste chips out of the liquid surface from below the liquid surface, under the combined action of gravity and the inclination angle of the plate surface, the excess cutting fluid carried by it flows back into the filter box along the plate surface, realizing the initial solid-liquid separation of waste chips and cutting fluid. Then, the chip removal scraper performs shearing and peeling from the interface between the root of the waste chips and the plate surface in a pushing and shaking manner, transforming the whole peeling of continuous large-area attached waste chips into multi-point dispersed shearing and peeling one by one, effectively breaking the adhesion interface formed between the waste chips and the plate surface, avoiding the residue of a very thin film layer of chips on the plate surface, and greatly improving the chip removal efficiency and the cutting fluid filtration and purification quality. 2. This invention uses a servo motor, crank plate, connecting column and chip removal scraper to drive the convex column to move up and down along the inside of the directional cylinder. With the elastic reset of the return spring, the chip removal scraper can be intermittently reciprocated. The intermittent directional vibration can apply a small throwing displacement along the chip removal direction to the stripped waste chips, causing the waste chips to move towards the collection side in a step manner, rather than relying solely on gravity to slide down. This prevents the waste chips from accumulating and bridging on the top of the chip removal scraper, ensuring that the chip removal channel is unobstructed throughout, and keeping the waste chip concentration of the waste liquid in the filter box at a low level for a long time. 3. The arrangement of the crank, chip scraper, and conveyor chain plate in this invention allows the asymmetric motion characteristics of the crank to create differentiated accelerations during the push and return phases, resulting in intermittent and discontinuous application of vibration from the chip scraper. During the push phase, the chip scraper is accelerated and pressed against the conveyor chain plate surface, simultaneously enhancing the scraping pressure and the instantaneous peak force required for chip removal, further improving the chip removal effect. During the return phase, the chip scraper slightly retracts, significantly reducing friction and dragging losses between the scraper edge and the plate surface. At the same time, the periodic vibration can prevent the formation of a continuous and dense residual chip adhesion layer on the plate surface, preventing the thickening of the skin on the plate surface after long-term operation. 4. By setting up the conveyor chain plate and the chip removal scraper, when the conveyor chain plate carrying waste chips passes through the turning point of the upper path, the movement direction of the plate changes abruptly. The adhesion state of the waste chips to the plate surface is locally destroyed by the inertial force. The originally tightly attached sheet-like and clump-like waste chips are lifted or slightly displaced, forming an initial loose gap between them and the plate surface. This provides a pre-loosening condition for the chip removal scraper to scrape, thereby effectively avoiding the problem of the chip removal scraper getting stuck and the conveyor chain plate surface being scratched due to excessive adhesion of waste chips, and extending the service life of the equipment components. 5. The present invention, through the setting of electric push rod, guide plate, support frame, chip rack and chip scraper, allows the chip scraper to be adjusted to an inclined L-shaped posture with an acute angle clamping the conveyor chain plate, so that the working edge cuts into the interface between the waste and the plate surface with a sharper wedge angle. The dragging force of the waste brought by the movement of the conveyor chain plate is decomposed into the sliding component force along the working surface, driving the waste to continuously climb along the working surface, thereby integrating the peeling and discharge of waste into a continuous process of the same movement. The adhesive resistance that originally needed to be actively overcome by the scraper is transformed into the peeling auxiliary force provided by the movement of the conveyor chain plate itself, so that the peeling and discharge actions are naturally connected, reducing the probability of waste re-accumulating at the root of the chip scraper. 6. This invention provides the chip removal scraper with higher torsional stiffness through a multi-link closed-loop adjustment structure, ensuring that the scraping angle is reliably maintained over a long period of time. At the same time, it ensures smooth flow of the chip removal channel on the back of the scraper, without interfering with the falling trajectory of the already stripped waste chips. 7. This invention, through the arrangement of a power motor, conveyor chain, and filter box, pushes the waste debris encased on the plate surface forward by one pulse stroke. This periodic forced push helps the conveyor chain overcome the tendency of waste debris to stagnate near the liquid surface due to buoyancy and surface tension, preventing waste debris from accumulating at the interface between the conveyor chain and the liquid surface. This ensures the continuous and uniform lifting of the encasing stroke. At the same time, during the rotation of the rotating corner plate, the concentric shaft drives the side arms on both sides to perform reciprocating circular motion along the side crossbar, forming a diversion and merging conveying mode of the rotating corner plate pushing and the side arms guiding. This orderly guides the floating and semi-suspended waste debris on both sides of the filter box to the encasing area of ​​the conveyor chain, thereby avoiding the formation of flow dead zones and sedimentation in the corner areas of the box, greatly improving the overall discharge rate of waste debris in the filter box, and ensuring the long-term stable filtration and debris removal capabilities of the equipment.

The protruding post 25 is used to strike the directional cylinder 26 and make the chip removal scraper 22 slightly shake along the top of the chip removal frame 21. A cleaning assembly 5 is provided inside the filter box 1. The cleaning assembly 5 is used to make the waste chips and waste liquid near the conveyor chain plate 12 flow in multiple dimensions. It should be emphasized that the conveyor chain plate 12 moves in a Z-shape and the chip removal scraper 22 has an interlaced tooth shape. The cleaning assembly 5 includes a rotating disc 53 and a curved arm 52 installed sequentially from left to right.

[0023] refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the top of the stabilizer 24 is provided with a micro-shaking component 3, which is used to drive the protrusion 25 to move up and down while moving the chip scraper 22 back and forth along the top of the chip rack 21. The micro-shaking component 3 includes a centering groove 31 opened at the bottom of the protrusion 25 and a servo motor 37 fixedly connected to one side of the stabilizer 24. A centering shaft 38 is installed inside the centering groove 31, and a crank 34 is movably sleeved on the outside of the centering shaft 38. A crank disk 36 is fixedly connected to the output end of the servo motor 37, and the crank disk 36 is located inside the stabilizer 24. A connecting post 35 is installed at one end of the crank plate 36, and one end of the connecting post 35 passes through the bottom end of the crank rod 34.

The hinge plate 41 is located above the chip removal frame 21. The top of the support frame 42 is fixedly connected to the bottom middle of the hinge plate 41.

The connecting rod assembly includes an electric push rod 43 fixedly connected to the top of the filter box 1. The telescopic end of the electric push rod 43 extends into the interior of the filter box 1 and is fixedly connected to a guide plate 44. A first limiting shaft 46 is installed at one end of the guide plate 44. A second limiting shaft 47 is installed on the side of the hinge plate 41 away from the filter box 1. A vertical plate frame 45 is connected between the second limiting shaft 47 and the first limiting shaft 46. A guide groove 48 is opened at the top of the filter box 1, which communicates with the interior of the filter box 1 to guide the movement of the guide plate 44.

[0024] Working principle: When using: refer to Figure 1 , Figure 2 and Figure 3 As shown, when it is necessary to perform dynamic solid-liquid coarse separation on the waste liquid and waste debris inside the filter box 1 to ensure stable filtration operation of the filter box 1 and maintain the long-term high efficiency of the equipment in filtration and debris removal. First, the receiving box 11 guides the waste liquid and waste chips generated by the processing equipment into the filter box 1, where the filter box 1 collects the mixture. Next, the power roller 13 starts its drive, causing the conveyor chain 12 to rotate in a V-shape inside the filter box 1. At this time, the upper section of the conveyor chain 12 moves upward from below the liquid surface inside the filter box 1. As the conveyor chain 12 passes through the liquid surface, the waste chips are carried along by the conveyor chain 12 and simultaneously detach from the cutting fluid surface. Under the combined action of gravity and the tilt angle of the conveyor chain 12, the excess cutting fluid carried along the conveyor chain 12 flows back into the filter box 1, while the waste chips, relying on the frictional adhesion and geometric embedding effect with the conveyor chain 12, continue to rise with the conveyor chain 12, completing the initial solid-liquid separation of the waste chips and cutting fluid, significantly improving the efficiency of the process. The liquid content of the waste chips carried out of the filter box 1 is reduced, and the cutting fluid is recovered in situ to ensure its continuous participation in the circulation filtration. When the conveyor chain plate 12 carrying the waste chips passes the turning point of the upper path, the direction of movement of the plate changes abruptly. The waste chips are subjected to inertial force, and the adhesion state with the plate surface is locally destroyed. The sheet-like and clump-like waste chips that were originally tightly attached to the plate surface are lifted or slightly displaced at the turning point, forming an initial loose gap with the plate surface. This provides a pre-loosening condition for the scraping operation of the chip removal scraper 22, effectively avoiding the problem of the chip removal scraper 22 getting stuck and the plate surface being scratched due to excessive adhesion of waste chips. Subsequently, the conveyor chain plate 12 continues to run, conveying the waste chips on its surface to the chip removal frame 21, so that the extended end of the chip removal scraper 22 is in stable contact with the surface of the conveyor chain plate 12. refer to Figure 2 , Figure 5 and Figure 6As shown, when the waste debris on the surface of the conveyor chain plate 12 comes into contact with the working edge of the chip removal scraper 22, it is divided into several discrete units by the staggered teeth of the edge. The chip removal scraper 22 performs shearing and peeling from the interface between the root of the waste debris and the plate surface in a pushing motion, transforming the whole piece of continuous large-area attached waste debris into a step-by-step operation of multi-point dispersed shearing and then peeling off one piece at a time. Subsequently, the waste debris removed from the surface of the conveyor chain plate 12 moves up along the working surface of the chip removal scraper 22 and is pushed out of the top of the chip removal scraper 22. Under the action of gravity, it falls freely along the non-working area on the back side of the chip removal scraper 22 into the inside of the chip discharge port 23. The waste debris is discharged from the outside of the filter box 1 by the collection area of ​​the chip discharge port 23. No waste debris is retained on the working surface of the chip removal scraper 22 throughout the process, realizing continuous circulation chip removal inside the filter box 1. refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, secondly, during the scraping operation of the chip removal scraper 22 on the surface of the conveyor chain plate 12, the servo motor 37 starts to drive the crank plate 36 to rotate along the inside of the connecting frame 24. The crank plate 36 synchronously drives the connecting column 35 to rotate in a circular motion. During the rotation of the connecting column 35, its outer wall forms a contact fit with the inside of the crank rod 34, synchronously pushing and pulling the crank rod 34 to reciprocate in an arc along the outer circumference of the crank plate 36, simultaneously completing the compound action of downward pressing and upward lifting. During the movement of the crank rod 34, it drives the centering shaft column 38 and the protrusion 25 to complete the reciprocating linear motion downward and upward. As the protrusion 25 moves upward, it moves upward along the inside of the directional cylinder 26 and forms a contact with the cylinder wall, pushing the chip discharge port 23 to swing slightly along the top of the chip removal frame 21. When the protrusion 25 moves downward, it moves downward along the inside of the directional cylinder 26 and resets. Spring 33 returns to its original position due to its elasticity, driving the directional cylinder 26 to move synchronously downward along the outside of the protrusion 25. Then, the directional cylinder 26 pushes the chip removal scraper 22 to complete high-frequency reciprocating vibration along the top of the chip removal frame 21. When the chip removal scraper 22 scrapes the waste chips off the plate surface and pushes them to the top of the scraper, the intermittent directional vibration can apply a small throwing displacement along the chip removal direction to the stripped waste chips, causing the waste chips to move towards the collection side in a stepping manner on the chip removal surface on the back of the chip removal scraper 22, rather than simply relying on gravity to slide down. This effectively prevents the waste chips from accumulating and bridging on the top of the chip removal scraper 22, ensuring that the chip removal channel is unobstructed throughout, and keeping the waste chip concentration of the waste liquid in the filter box 1 at a low level for a long time. At the same time, the asymmetrical motion characteristics of the crank 34 make its acceleration in the pushing stage and return stage different, so that the vibration of the chip removal scraper 22 is applied intermittently and discontinuously. refer to Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, during the push phase, the chip removal scraper 22 is accelerated and pressed against the surface of the conveyor chain plate 12, which increases the scraping pressure of the chip removal scraper 22 simultaneously when the instantaneous peak force required for chip removal occurs, greatly improving the removal effect. During the return phase, the chip removal scraper 22 is slightly retracted to reduce friction and drag loss between the scraper edge and the plate surface. During the intermittent vibration stop, the chip removal scraper 22 resumes steady-state pushing operation to stably remove and discharge the loosened chips. During the vibration excitation, the unremoved chips newly entering the working area of ​​the chip removal scraper 22 are simultaneously subjected to vibration pretreatment. At the same time, the periodic vibration can prevent the formation of a continuous and dense residual chip adhesion layer on the plate surface, preventing the thickening of the skin on the plate surface after long-term operation. refer to Figure 2 and Figure 5 As shown, secondly, after the chip removal scraper 22 has continuously completed the scraping operation on the surface of the conveyor chain plate 12, when it is necessary to adjust the clamping angle between the chip removal scraper 22 and the conveyor chain plate 12, the electric push rod 43 starts the telescopic drive, causing its telescopic end to move deeper into the filter box 1. The electric push rod 43 simultaneously pushes the guide plate 44 to move along the guide groove 48 and the inside of the filter box 1 in the direction of force. During the movement of the guide plate 44, it drives the first limiting shaft column 46 to move downward synchronously, so that the outer wall of the first limiting shaft column 46... The vertical plate 45 comes into contact with the interior of the frame, pushing it downwards. Because both ends of the vertical plate 45 are constrained by the first limiting shaft 46 and the second limiting shaft 47 respectively, the direction of movement of the vertical plate 45 is precisely limited. During its downward movement, the interior of the vertical plate 45 engages with the outer wall of the second limiting shaft 47, causing the second limiting shaft 47 to drive one end of the hinge plate 41 downwards along the interior of the filter box 1. Simultaneously, due to the hinged constraint between the hinge plate 41 and the interior of the filter box 1, its rotation... The angle is limited, causing the hinge plate 41 to swing circumferentially along a fixed axis inside the filter box 1, thereby driving the hinge plate 41 and the second limiting shaft 47 to move in an arc along the inside of the filter box 1. As the hinge plate 41 swings, it simultaneously drives the support frame 42 to move closer to the outside of the conveyor chain plate 12, so that the support frame 42, through the hinge plate 41, forms a lever transmission with the second limiting shaft 47 along the inside of the filter box 1, completing the tilt angle adjustment of the chip conveyor 21. After the chip conveyor 21 is adjusted in a closed loop through the multi-link node, its closed linkage chain can... To provide higher torsional stiffness to the chip removal scraper 22, ensuring long-term stable and reliable scraping angle, while keeping the chip removal channel on the back of the chip removal scraper 22 in a smooth and unobstructed manner in space, without interfering with the falling trajectory of the stripped waste chips, when the chip removal scraper 22 is adjusted to be in an inclined L-shaped posture with the conveyor chain plate 12, the working surface of the chip removal scraper 22 is no longer perpendicular to the surface of the conveyor chain plate 12, but is in an acute angle clamping state, so that the working edge of the chip removal scraper 22 cuts into the interface between the waste chips and the conveyor chain plate 12 with a sharper wedge angle; refer to Figure 2 and Figure 6As shown, in this posture, the dragging force of the conveyor chain plate 12 on the waste chips is decomposed into a sliding component force along the working surface of the chip removal scraper 22. This not only presses the waste chips more tightly against the upper part of the working surface of the chip removal scraper 22, but also drives the waste chips to continuously rise along the working surface of the chip removal scraper 22 away from the conveyor chain plate 12. This integrates the peeling and discharge of waste chips into a continuous process of the same movement. The adhesion resistance that originally needed to be actively overcome by the chip removal scraper 22 is partially transformed into the peeling auxiliary force provided by the movement of the conveyor chain plate 12 itself. This allows the two actions of peeling and discharging waste chips to be naturally connected on the working surface of the chip removal scraper 22, reducing the probability of waste chips re-accumulating at the root of the chip removal scraper 22. refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, finally, to ensure the continuous and stable discharge of waste liquid and waste debris inside the filter box 1, maintain the stable solid-liquid separation of waste liquid inside the filter box 1, reduce the sedimentation and accumulation of waste debris inside the filter box 1, and ensure the continuous and stable operation of the filter box 1 during filtration, the power motor 51 is started and driven, driving its output end to rotate synchronously inside the filter box 1. The output end of the power motor 51 synchronously drives the crank arm 52 to rotate circumferentially inside the filter box 1. At this time, the rotating angle disk 53 forms an eccentric transmission cooperation with the power motor 51 through the crank arm 52. During the rotation of the crank arm 52, its interior forms an abutment cooperation with the horizontal shaft column 54, synchronously pushing and pulling the horizontal shaft column 54 to complete the eccentric rotational movement inside the filter box 1. The rotating angle disk 53 moves synchronously with the horizontal shaft column 54. The horizontal column 54 rotates eccentrically inside the filter box 1. Because the rotation center of the horizontal column 54 is off-center from its own geometric center, when the horizontal column 54 rotates to the eccentric push stage, its surface approaches the area of ​​the conveyor chain plate 12 inside the filter box 1, forming contact with the waste debris pile already wrapped on the surface of the conveyor chain plate 12, pushing the waste debris forward along the conveyor chain plate 12 for one pulse stroke. When the horizontal column 54 enters the eccentric return stage, it moves radially away from the surface of the conveyor chain plate 12, and the waste debris continues to run with the conveyor chain plate 12, waiting for the next cycle of pushing operation. The periodic forced pushing formed by the eccentric movement of the horizontal column 54 can help the conveyor chain plate 12 overcome the buoyancy and surface tension of the liquid near the liquid surface caused by the waste debris. The tendency to retain waste effectively prevents it from accumulating at the liquid surface interface of the conveyor chain plate 12, ensuring the continuous and uniform lifting of the separation plate. As the rotating disk 53 rotates, it synchronously drives the concentric shaft column 57 to reciprocate. The two ends of the concentric shaft column 57 are respectively limited and constrained by the side arm 56 and the rotating disk 53, so that the rotation direction of the concentric shaft column 57 is precisely defined. During the rotation of the rotating disk 53, its interior and the outer wall of the concentric shaft column 57 form a contact fit, synchronously pushing and pulling the concentric shaft column 57 to reciprocate. During the movement of the concentric shaft column 57, the angle between the rotating disk 53 and the side arm 56 changes from horizontal to vertical, and then from vertical to horizontal, in a reciprocating cycle. At the same time, the side arm 56 During the movement, the side transverse column 55 rotates in a circular motion. Through the reciprocating rotation of the two sets of side arms 56, the two sets of side arms 56 alternately move closer and further away from each other as they move along the inside of the filter box 1. When the rotating corner plate 53 pushes the waste debris to one side of the conveyor chain plate 12, the rotation direction of the side arms 56 can guide the floating and semi-suspended waste debris on the other side of the filter box 1 to the subsequent pushing area of ​​the rotating corner plate 53. This forms a diversion and merging conveying mode in which the rotating corner plate 53 pushes and the side arms 56 guide, so that the waste debris on both sides of the filter box 1 can be orderly guided to the entrainment area of ​​the conveyor chain plate 12, avoiding the formation of flow dead zones in the corner areas of the box and the generation of sedimentation and agglomeration, and greatly improving the overall discharge of waste debris in the filter box 1.
