[0002] In the process of treating industrial sludge, the sludge in the sewage is separated from the sewage, thereby eliminating organic matters, pathogenic bacteria and other toxic and harmful substances that emit foul odors, cause diseases and pollute the environment, making the sewage more hygienic and stable.

[0003] The patent with the application number CN201922149232.4 discloses a filtration device suitable for industrial sewage discharge, including a filtration tank and a sedimentation tank. One side of the top of the filtration tank is provided with a sewage inlet pipe. In the filtration tank, a first filter plate and a second filter plate are arranged successively from top to bottom. Both ends of the first filter plate and the second filter plate are connected to a vibration adjustment device. One side of the bottom of the filtration tank is connected to the water inlet end of a water delivery pipe through a water pump. The water outlet end of the water delivery pipe is connected to a position near the top of the sedimentation tank. One side of the top of the sedimentation tank is connected with a chemical addition pipe. An overflow pipe is arranged at a position near the top of the other side of the sedimentation tank. A conical cavity is arranged at a position near the bottom of the sedimentation tank. A slag discharge pipe is arranged at the middle position of the bottom of the sedimentation chamber. Through the structural settings of the filtration tank and the sedimentation tank, the present utility model integrates a sewage discharge filtration device that combines filtration, sedimentation, disinfection and discharge. The sewage treatment effect is good and the efficiency is high. Although this patent solves the above problems, there is still a problem that the sewage and substances insoluble in water in the sewage are not effectively separated. Therefore, it is very necessary to design a sewage filtration device for industrial sewage discharge that can environmentally protect the sewage separation and treatment. Summary of the Invention

[0004] The purpose of the present invention is to provide a sewage filtration device for industrial sewage discharge to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A sewage filtering device for industrial sewage discharge, including a vortex end shell, and further including a treatment structure and a separation component; the treatment structure includes an input port, a support frame, an output shaft, a vortex plate, a treatment tank, a cleaning tank, a drainage port, and a sewage discharge port. The side of the input port is fixedly connected to the side of the vortex end shell. The support frame is fixedly connected to the bottom side of the vortex end shell. The output shaft is rotatably connected to the inner axis of the vortex end shell. The vortex plate is fixedly connected to the outer side of the output shaft. The treatment tank is arranged on the rear side of the separation component. The cleaning tank is arranged on the bottom side of the separation component. The drainage port is fixedly connected to the rear side of the treatment tank. The sewage discharge port is fixedly connected to the bottom surface of the cleaning tank; the separation component includes a separation end shell, a swing shaft, a swing groove plate, a fitting scraper, an arc-shaped filter screen, and a flow channel. The separation end shell is fixedly connected to the rear side of the vortex end shell. The swing shaft is fixedly connected to the outer side of the output shaft. The swing groove plate is fixedly connected to the outer side of the swing shaft. The fitting scraper is slidably connected to the inner side of the swing groove plate. The arc-shaped filter screen is fixedly connected to the inner side of the separation end shell. The flow channel is arranged below the arc-shaped filter screen. The separation end shell is fixedly connected to the treatment tank. The cleaning tank is fixedly connected to the separation end shell. A spring is arranged on the inner side of the swing groove plate. Through the above structure, when sewage needs to be treated, the sewage is connected to the input port on the side of the vortex end shell through an external pipeline. Thus, the sewage flow drives the vortex plate to rotate, and the rotation of the vortex plate drives the output shaft to rotate, and the swing shaft operates. Through the rotation of the swing shaft, the swing groove plate and the fitting scraper connected to the swing shaft rotate together with it. During this process, the swing groove plate and the fitting scraper release elastic force through the spring on the inner side, so that the end of the fitting scraper always fits the inner side of the arc-shaped filter screen. And the sewage inside the separation end shell will be filtered through the arc-shaped filter screen. Then, the sewage seeps down from the bottom surface of the arc-shaped filter screen, and the sludge and impurities insoluble in water are left on the arc-shaped filter screen. The filtered sewage passes through the arc-shaped filter screen and enters the flow channel and flows out. Subsequently, with the fitting scraper rotating with the swing shaft, the fitting scraper scrapes the sludge and impurities from the arc-shaped filter screen. And along with the continuous rotation of the fitting scraper, the sludge and impurities on the fitting scraper are pushed into the cleaning tank and collected, and then discharged through the sewage discharge port for cleaning. The power of the water flow is utilized to drive the rotation of the vortex plate, and then the water flow is used as the driving force of the overall structure, thereby reducing the consumption of electric energy and other energy sources and enhancing the environmental protection of the treatment. At the same time, the rotation of the output shaft eccentrically arranged in the input port drives the swing groove plate and the fitting scraper to flip, so that the fitting scraper always fits the arc-shaped filter screen, transfers the residual sludge and impurities on the arc-shaped filter screen, and cleans the arc-shaped filter screen.

[0006] A filtering and processing device is fixedly connected to the rear end of the output shaft. The filtering and processing device includes a reciprocating structure and a cleaning structure. The reciprocating structure includes a connecting shaft, a crank, a short shaft, and a hinged plate. The connecting shaft is fixedly connected to the end of the output shaft. The crank is fixedly connected to the end of the connecting shaft. The short shaft is fixedly connected to the inner side of the crank. The hinged plate is rotatably connected to the outside of the short shaft. The cleaning structure includes a filter screen square groove and a baffle. The filter screen square groove is fixedly connected to the bottom surface of the hinged plate. The baffle is fixedly connected to the inside of the processing box. The processing box is slidably connected to the filter screen square groove. The end of the baffle protrudes inward with a triangular cross-section. The crank is symmetric about the vertical midline of the short shaft. With the above structure, when the output shaft rotates, it will drive the coaxial connecting shaft to rotate, and the rotation of the connecting shaft will drive the connected crank to swing. The crank drives the short shaft to make a circular motion around the axis of the connecting shaft. The short shaft drives the connected hinged plate to move up and down, so that the hinged plate moves up and down reciprocally to drive the filter screen square groove to move up and down. By filling the filter screen square groove with a lighter filtering material, the sewage flowing out of the flow-through groove enters the processing box, and the filter screen square groove and the internal filling material are used for filtering to further improve the overall water quality. At the same time, by moving the filter screen square groove up and down, the outer side of the filter screen square groove is attached to the inner side of the baffle, and then the protruding part on the inner side of the baffle scrapes off the impurities blocking the filter holes on the outer side of the filter screen square groove, thereby cleaning the outer side part of the filter screen square groove. The filter screen square groove moves up and down to shake off the impurities scraped off the outer side of the filter screen square groove. The filter screen square groove moves up and down to clean the impurities blocking the filter holes on the outer side of the filter screen square groove in real time.

[0007] A drum air device is provided on the bottom side of the filter screen square groove. The drum air device includes an aeration structure and a cleaning structure. The aeration structure includes a jet plate and an air outlet pipe. The jet plate is fixedly connected to the side surface of the baffle plate, and the air outlet pipe is fixedly connected to the bottom surface of the jet plate. The cleaning structure includes an agitation pipe, a collection end shell, and a side groove. The side groove is provided between the baffle plate and the filter screen square groove. The agitation pipe is fixedly connected to the outer side surface of the treatment tank, and the collection end shell is fixedly connected to the right side surface of the treatment tank. Small holes are formed on the surface of the jet plate and penetrate into the interior of the jet plate. The air outlet pipe is fixedly connected to the baffle plate, the agitation pipe is communicated with the side groove, and the collection end shell is communicated with the side groove. Through the above structure, when the bottom surface of the filter screen square groove moves downward, the filter screen square groove will slide inside the two baffle plates, and the extrusion chamber will be squeezed by the bottom surface of the filter screen square groove, so that the air in the extrusion chamber is discharged, and the air is output through the air outlet pipe connected to the side surface of the baffle plate. The gas is ejected from the jet plate connected to the end of the air outlet pipe. When the filter screen square groove returns upward, the extrusion chamber sucks in external air through the one-way pipe connected to the side surface of the treatment tank and ejects the gas through the small holes on the surface of the jet plate. Thus, the ejected gas floats upward in the sewage between the filter screen square grooves, aerates the sewage in the treatment tank, increases the oxygen content of the sewage inside the treatment tank, and promotes the water flow to circulate. At the same time, when the filter screen square groove is squeezed downward, part of the gas in the extrusion chamber is transmitted upward through the side agitation pipe, and the residual filter impurities in the side groove are pushed by the agitation, and as the filter screen square groove reciprocates, the filter impurities in the side groove are gradually pushed into the collection end shell for collection, thereby assisting in cleaning the inner side of the side groove and preventing the residual filter residues on the inner side of the side groove from affecting the normal sliding of the filter screen square groove.

[0008] A shock absorption device is provided at the bottom of the treatment tank. The shock absorption device includes a support platform plate, a shock absorption base, a convex strip, and a shock absorption spring. The support platform plate is fixedly connected to the bottom surface of the treatment tank. The shock absorption base is slidably connected to the outer bottom end of the support platform plate. The convex strip is fixedly connected to the surface of the support platform plate. The shock absorption spring is fixedly connected to the bottom surface of the support platform plate, and the bottom surface of the shock absorption spring is fixedly connected to the shock absorption base. The convex strip is slidably connected to the treatment tank. Through the above structure, when the treatment tank vibrates as a whole, the vibration is transmitted downward through the support platform plate connected to the bottom, and the support platform plate squeezes the bottom shock absorption spring, and at the same time, the support platform plate slides inside the shock absorption base, so as to use the force of the shock absorption spring and the cooperation of the support platform plate sliding between the shock absorption bases to play a shock absorption role. At the same time, the convex strip contacts the bottom surface of the filter screen square groove, and the filter screen square groove vibrates accordingly.

By using the power of water flow to drive the rotation of the vortex plate, and then using the water flow as the driving force of the overall structure, the consumption of electric energy and other energy sources is reduced, and the environmental protection of the treatment is improved. At the same time, the sludge and sewage are separated, and the arc-shaped filter screen is prevented from being blocked, further promoting the improvement of the filtering effect; The present invention is provided with a connecting shaft, a crank, a short shaft, a hinged plate, a filter screen square groove, and a baffle.

[0010] The present invention is provided with a jet plate, an agitation tube, a collection end shell, a side groove, an air outlet pipe, and an extrusion chamber. The ejected gas floats upward in the sewage between the filter screen square grooves, aerates the sewage in the treatment tank, increases the oxygen content of the sewage inside the treatment tank, and promotes the circulation of the water flow. At the same time, the filtered impurities in the side groove are pushed into the collection end shell for collection, thereby assisting in the cleaning inside the side groove and preventing the residual filtered residues inside the side groove from affecting the normal sliding of the filter screen square groove; The present invention is provided with a support platform plate, a shock-absorbing base, a convex strip, and a shock-absorbing spring. By using the force of the shock-absorbing spring and the sliding of the support platform plate between the shock-absorbing bases, a shock-absorbing effect is achieved. At the same time, the convex strip contacts the bottom surface of the filter screen square groove, and then the filter screen square groove generates vibration. Description of the Drawings

Embodiment 1

[0013] Please refer to Figures 1-4, the present invention provides a technical solution: a sewage filtration device for industrial sewage discharge, including a vortex end shell 1, and further including a treatment structure and a separation component 4; the treatment structure includes an input port 2, a support frame 3, an output shaft 7, a vortex plate 9, a treatment tank 10, a cleaning tank 11, a drainage port 12, and a sewage discharge port 13. The side of the input port 2 is fixedly connected to the side of the vortex end shell 1. The support frame 3 is fixedly connected to the bottom side of the vortex end shell 1.

The treatment tank 10 is arranged on the rear side of the separation component 4. The cleaning tank 11 is arranged on the bottom side of the separation component 4. The drainage port 12 is fixedly connected to the rear side of the treatment tank 10. The sewage discharge port 13 is fixedly connected to the bottom surface of the cleaning tank 11;The separation component 4 includes a separation end shell 41, a swing shaft 42, a swing groove plate 43, a fitting scraper 44, an arc-shaped filter screen 45, and a flow-through groove 46. The separation end shell 41 is fixedly connected to the rear side of the eddy current end shell 1. The swing shaft 42 is fixedly connected to the outer side of the output shaft 7.

The arc-shaped filter screen 45 is fixedly connected to the inner side of the separation end shell 41. The flow-through groove 46 is arranged below the arc-shaped filter screen 45. The separation end shell 41 is fixedly connected to the treatment tank 10, and the cleaning tank 11 is fixedly connected to the separation end shell 41. A spring is arranged on the inner side of the swing groove plate 43. With the above structure, when sewage needs to be treated, the sewage is connected to the input port 2 on the side of the eddy current end shell 1 through an external pipeline, so that the sewage flow drives the eddy current plate 9 to rotate, and the rotation of the eddy current plate 9 drives the output shaft 7 to rotate, and the swing shaft 42 operates. Through the rotation of the swing shaft 42, the swing groove plate 43 and the fitting scraper 44 connected to the swing shaft 42 are flipped and rotated together. During this process, the swing groove plate 43 and the fitting scraper 44 release elastic force through the spring on the inner side, so that the end of the fitting scraper 44 is always in contact with the inner side of the arc-shaped filter screen 45. The sewage passing through the inside of the separation end shell 41 is filtered by the arc-shaped filter screen 45. Then, the sewage seeps down from the bottom surface of the arc-shaped filter screen 45, and the sludge and impurities insoluble in water are left on the arc-shaped filter screen 45. The filtered sewage passes through the arc-shaped filter screen 45 and flows into the flow-through groove 46 and then out. Subsequently, as the fitting scraper 44 flips and rotates along with the swing shaft 42, the fitting scraper 44 scrapes the sludge and impurities from the arc-shaped filter screen 45. Along with the continuous flipping of the fitting scraper 44, the sludge and impurities on the fitting scraper 44 are pushed into the cleaning tank 11 for collection, and then discharged through the sewage discharge port 13 for cleaning. The power of the water flow is used to drive the rotation of the eddy current plate 9, and then the water flow is used as the driving force of the overall structure, thereby reducing the consumption of electric energy and other energy sources and improving the environmental protection of the treatment. At the same time, the rotation of the output shaft 7 eccentrically arranged in the input port 2 drives the swing groove plate 43 and the fitting scraper 44 to flip, so that the fitting scraper 44 is always in contact with the arc-shaped filter screen 45, transfers the residual sludge and impurities on the arc-shaped filter screen 45, and cleans the arc-shaped filter screen 45.;

[0014] A filtering and processing device 5 is fixedly connected to the rear end of the output shaft 7. The filtering and processing device 5 includes a reciprocating structure and a cleaning structure. The reciprocating structure includes a connecting shaft 51, a crank 52, a short shaft 53, and a hinged plate 54. The connecting shaft 51 is fixedly connected to the end of the output shaft 7. The crank 52 is fixedly connected to the end of the connecting shaft 51. The short shaft 53 is fixedly connected to the inner side of the crank 52. The hinged plate 54 is rotatably connected to the outside of the short shaft 53. The cleaning structure includes a filter screen square groove 55 and a baffle 56. The filter screen square groove 55 is fixedly connected to the bottom surface of the hinged plate 54. The baffle 56 is fixedly connected to the inside of the processing tank 10. The processing tank 10 is slidably connected to the filter screen square groove 55. The end of the baffle 56 protrudes inward and has a triangular cross-section. The crank 52 is symmetric about the vertical midline of the short shaft 53. With the above structure, when the output shaft 7 rotates, it will drive the coaxially connected connecting shaft 51 to rotate, and the rotation of the connecting shaft 51 will drive the connected crank 52 to swing. The crank 52 drives the short shaft 53 to make a circular motion around the axis of the connecting shaft 51. The short shaft 53 is used to drive the connected hinged plate 54 to move up and down, so that the up and down reciprocating motion of the hinged plate 54 drives the filter screen square groove 55 to move up and down. By filling the filter screen square groove 55 with a lighter filtering material, the sewage flowing out of the flow-through groove 46 enters the processing tank 10, and the filter screen square groove 55 and the internal filling material are used for filtration to further improve the overall water quality. At the same time, by moving the filter screen square groove 55 up and down, the outer side of the filter screen square groove 55 is fitted to the inner side of the baffle 56, so that the protruding part on the inner side of the baffle 56 scrapes off the impurities blocking the filter holes on the outer side of the filter screen square groove 55, thereby cleaning the outer side part of the filter screen square groove 55. The filter screen square groove 55 moves up and down to shake off the impurities scraped off the outer side of the filter screen square groove 55. The filter screen square groove 55 moves up and down to clean the impurities blocking the filter holes on the outer side of the filter screen square groove 55 in real time.

[0015] Working principle: When sewage needs to be treated, connect the sewage to the input port 2 on the side of the eddy current end shell 1 through an external pipeline, so that the sewage enters the inside of the eddy current end shell 1. Then, the sewage flow drives the eddy current plate 9 to rotate, and the rotation of the eddy current plate 9 drives the output shaft 7 to rotate. Furthermore, when the output shaft 7 rotates, it drives the swing shaft 42 connected to the outside of the output shaft 7 to operate. Through the rotation of the swing shaft 42, the swing groove plate 43 and the fitting scraper 44 connected to the swing shaft 42 are flipped and rotated together. During this process, the swing groove plate 43 and the fitting scraper 44 release elastic force through the spring inside, so that the end of the fitting scraper 44 always fits the inner side of the arc-shaped filter screen 45. The sewage inside the separation end shell 41 is filtered through the arc-shaped filter screen 45. Then, the sewage seeps down from the bottom of the arc-shaped filter screen 45, leaving the sludge and impurities insoluble in water on the arc-shaped filter screen 45. The filtered sewage passes through the arc-shaped filter screen 45 and flows out into the flow-through groove 46. Subsequently, as the fitting scraper 44 flips and rotates along with the swing shaft 42, the fitting scraper 44 scrapes the sludge and impurities from the arc-shaped filter screen 45. Along with the continuous flipping of the fitting scraper 44, the sludge and impurities on the fitting scraper 44 are pushed into the cleaning box 11 for collection, and then discharged through the sewage discharge port 13 for cleaning. Utilize the power of water flow to drive the rotation of the eddy current plate 9, and then use the water flow as the driving force of the overall structure, thereby reducing the consumption of electric energy and other energy sources and improving the environmental protection of the treatment. At the same time, utilize the rotation of the output shaft 7 eccentrically arranged in the input port 2 to drive the flipping of the swing groove plate 43 and the fitting scraper 44, so that the fitting scraper 44 always fits the arc-shaped filter screen 45, transfer the residual sludge and impurities on the arc-shaped filter screen 45, and clean the arc-shaped filter screen 45, thereby separating the sludge and sewage, and preventing the arc-shaped filter screen 45 from being blocked, further promoting the improvement of the filtering effect; While the output shaft 7 rotates, it drives the connected shaft 51 that is coaxially connected to rotate. The rotation of the connected shaft 51 drives the connected crank 52 to swing. The crank 52 drives the short shaft 53 to perform a circular motion around the axis of the connected shaft 51. The short shaft 53 drives the connected articulated plate 54 to move up and down. Thus, the reciprocating up and down movement of the articulated plate 54 drives the filter screen square groove 55 to move up and down. By filling the filter screen square groove 55 with lighter filter materials, the sewage flowing out of the flow channel 46 enters the treatment tank 10 and is filtered through the filter screen square groove 55 and the internal filling materials, further improving the overall water quality. At the same time, by using the up and down movement of the filter screen square groove 55, the outer side surface of the filter screen square groove 55 is attached to the inner side of the baffle 56. Furthermore, the protruding part on the inner side of the baffle 56 scrapes off the impurities blocking the filter holes on the outer side of the filter screen square groove 55, thereby cleaning the outer side part of the filter screen square groove 55. Through the up and down movement of the filter screen square groove 55, the impurities scraped off the outer side of the filter screen square groove 55 are shaken off. Through the up and down movement of the filter screen square groove 55, the impurities blocking the filter holes on the outer side of the filter screen square groove 55 are cleaned in real time, thus preventing the filter impurities from blocking the side of the filter screen square groove 55 and improving the filtering effect at the same time. Embodiment 2

[0016] Please refer to Figures 5-7, the present invention provides a technical solution: a head air blowing device 6 is provided on the bottom side of the filter screen square groove 55. The air blowing device 6 includes an aeration structure and a cleaning structure. The aeration structure includes a jet plate 61 and an air outlet pipe 65. The jet plate 61 is fixedly connected to the side surface of the baffle 56, and the air outlet pipe 65 is fixedly connected to the bottom surface of the jet plate 61. The cleaning structure includes an agitation pipe 62, a collection end shell 63, and a side groove 64. The side groove 64 is provided between the baffle 56 and the filter screen square groove 55. The agitation pipe 62 is fixedly connected to the outer side surface of the treatment tank 10, and the collection end shell 63 is fixedly connected to the right side surface of the treatment tank 10. Small holes are formed on the surface of the jet plate 61 and penetrate into the interior of the jet plate 61. The air outlet pipe 65 is fixedly connected to the baffle 56. The agitation pipe 62 is communicated with the side groove 64, and the collection end shell 63 is communicated with the side groove 64. Through the above structure, while the bottom surface of the filter screen square groove 55 moves downward, the filter screen square groove 55 will slide inside the two baffles 56, and the bottom surface of the filter screen square groove 55 will squeeze the extrusion chamber 66, so that the air in the extrusion chamber 66 is discharged, and the air is output through the air outlet pipe 65 connected to the side surface of the baffle 56. The gas is ejected from the jet plate 61 connected to the end of the air outlet pipe 65. When the filter screen square groove 55 resets upward, the extrusion chamber 66 inhales external air through the one-way pipe connected to the side surface of the treatment tank 10, and the gas is ejected through the small holes on the surface of the jet plate 61, so that the ejected gas floats upward in the sewage between the filter screen square grooves 55, aerates the sewage in the treatment tank 10, increases the oxygen content of the sewage inside the treatment tank 10, and promotes the water flow to circulate. At the same time, while the filter screen square groove 55 is being squeezed downward, part of the gas in the extrusion chamber 66 is transmitted upward through the side agitation pipe 62, and then the residual filter impurities in the side groove 64 are pushed by the air blowing. As the filter screen square groove 55 reciprocates, the filter impurities in the side groove 64 are gradually pushed into the collection end shell 63 for collection, thereby assisting in the cleaning of the inner side of the side groove 64 and preventing the residual filter residues on the inner side of the side groove 64 from affecting the normal sliding of the filter screen square groove 55.

[0017] A shock-absorbing device 8 is provided at the bottom of the processing box 10. The shock-absorbing device 8 includes a support platen 81, a shock-absorbing base 82, a rib 83, and a shock-absorbing spring 84. The support platen 81 is fixedly connected to the bottom surface of the processing box 10. The shock-absorbing base 82 is slidably connected to the outer bottom end of the support platen 81. The rib 83 is fixedly connected to the surface of the support platen 81. The shock-absorbing spring 84 is fixedly connected to the bottom surface of the support platen 81. The bottom surface of the shock-absorbing spring 84 is fixedly connected to the shock-absorbing base 82. The rib 83 is slidably connected to the processing box 10. Through the above structure, when the entire processing box 10 vibrates, the vibration is transmitted downward through the support platen 81 connected to the bottom, causing the support platen 81 to compress the bottom shock-absorbing spring 84 and allowing the support platen 81 to slide inside the shock-absorbing base 82. Thus, by utilizing the force of the shock-absorbing spring 84 and the cooperative sliding of the support platen 81 between the shock-absorbing bases 82, the shock-absorbing effect is achieved. At the same time, the rib 83 contacts the bottom surface of the filter screen square groove 55, thereby causing the filter screen square groove 55 to vibrate.

[0018] Working principle: While the bottom surface of the filter screen square groove 55 moves downward, it causes the filter screen square groove 55 to slide inside the two baffles 56 and compresses the compression chamber 66 through the bottom surface of the filter screen square groove 55, forcing the air in the compression chamber 66 and allowing the air to be output through the air outlet pipe 65 connected to the side of the baffle 56. The gas is ejected from the jet plate 61 connected to the end of the air outlet pipe 65. When the filter screen square groove 55 returns upward, the compression chamber 66 inhales external air through the one-way pipe connected to the side of the processing box 10. Since many small holes are provided on the upper side of the jet plate 61 and most of the small holes are of a one-way flow structure, the gas is ejected through the small holes on the surface of the jet plate 61, causing the ejected gas to float upward in the sewage between the filter screen square grooves 55, aerating the sewage in the processing box 10, increasing the oxygen content of the sewage inside the processing box 10, and promoting the circulation of the water flow. At the same time, while the filter screen square groove 55 is being compressed downward, a part of the gas in the compression chamber 66 is transmitted upward through the side agitation pipe 62, and then the residual filter impurities in the side groove 64 are pushed by the air injection, and as the filter screen square groove 55 reciprocates, the filter impurities in the side groove 64 are gradually pushed into the collection end shell 63 for collection, thereby assisting in cleaning the inside of the side groove 64 and preventing the residual filter residues inside the side groove 64 from affecting the normal sliding of the filter screen square groove 55; When the entire processing box 10 vibrates, the vibration is transmitted downward through the support platen 81 connected to the bottom, causing the support platen 81 to compress the bottom shock-absorbing spring 84 and allowing the support platen 81 to slide inside the shock-absorbing base 82. Thus, by utilizing the force of the shock-absorbing spring 84 and the cooperative sliding of the support platen 81 between the shock-absorbing bases 82, the shock-absorbing effect is achieved. At the same time, the rib 83 contacts the bottom surface of the filter screen square groove 55, thereby causing the filter screen square groove 55 to vibrate.
