[0041] A separation component 3, wherein the separation component 3 comprises a vertical filter plate 30, wherein the vertical filter plate 30 is slidably arranged inside the sedimentation tank 1, wherein a roller 31 is rotatably arranged at the lower end of the vertical filter plate 30, wherein a lever 310 is arranged outside the roller 31, wherein a receiving portion 300 is further arranged at the lower end of the vertical filter plate 30, wherein a material-discharging wire 3000 is arranged inside the receiving portion 300, wherein two movable racks 32 are symmetrically arranged on the cleaning component 2, wherein two rotating gears 33 are symmetrically arranged at both ends of the roller 31, wherein when the cleaning component 2 moves close to the vertical filter plate 30, the movable rack 32 is meshed with the rotating gear 33;

[0042] The vertical filter plate 30 includes a pull rod 301, the pull rod 301 is slidably arranged on the upper end of the vertical filter plate 30, a plurality of steel ropes 302 are evenly arranged along the length direction of the pull rod 301 at the lower end, the steel rope 302 is slidably arranged inside the vertical filter plate 30, the lower end of the steel rope 302 is connected to the lower end of the containing portion 300, and a return spring 303 is sleeved on the outer side of the steel rope 302 at the containing portion 300.

[0043] In another embodiment provided by the present invention, the separation component 3 further includes a frame 34, the upper end of the frame 34 is arranged at an angle, a cylindrical installation space 340 is arranged inside the frame 34, and the installation space 340 is arranged at an angle, and the installation space 340 is connected to the sedimentation tank 1 through a drop port, and an installation shaft 35 is rotatably arranged in the installation space 340, a spiral auger 36 is arranged on the outside of the installation shaft 35, one end of the spiral auger 36 is connected to the output end of the separation motor 37 through a coupling, a sealing plate 38 is arranged between the separation motor 37 and the spiral auger 36, and a crushing knife 39 is arranged at one end of the installation shaft 35 close to the separation motor 37, and the crushing knife 39 is used to stir and crush impurities such as agglomerated sludge entering the installation space 340;

[0044] The specific implementation method is as follows: the sludge and other impurities in the sedimentation tank 1 are scraped off from the bottom inclined surface 10 by the cleaning component 2 and transported to the vertical filter plate 30, so that the vertical filter plate 30 first filters and cleans the sludge and other impurities, so that the sludge and other impurities with too large particles enter the containing part 300 for collection, and the sludge and other impurities with smaller particles fall on the upper end of the frame 34 after passing through the vertical filter plate 30, and the sludge and other impurities falling on the upper end of the frame 34 are inclinedly arranged so that the sludge and other impurities falling thereon fall from the drop opening into the installation space 340, and at this time, the separation motor 37 drives the installation shaft 35 to rotate, so that the installation shaft 35 drives the spiral auger 36 to rotate, so that the spiral auger 36 will fall into the installation space 3 The sludge and other impurities in 40 are transported to the conveying component 4, and when the sludge and other impurities are transported by the conveying component 4, the separation motor 37 drives the crushing knife 39 to rotate through the mounting shaft 35 so that the crushing knife 39 can rotate and crush the sludge and other impurities. At the same time, the spiral auger 36 can also rotate and crush the sludge and other impurities, so that the particles of the sludge and other impurities are broken smaller, which is convenient for the spiral auger 36 to transport the sludge and other impurities to the conveying component 4, and convenient for the conveying component 4 to suck the sludge and other impurities to the outside of the sedimentation tank 1; the sealing plate 38 is used to separate the sludge and other impurities from the separation motor 37, so as to avoid the separation motor 37 from contacting the sludge and other impurities and causing damage or shortening the service life.

[0045] In another embodiment provided by the present invention, a conveyor belt 341 is provided at the upper end of the frame 34, and the conveyor belt 341 is rotatably provided at the upper end of the frame 34, and the conveyor belt 341 is obliquely arranged along the upper end of the frame 34;

[0046] The specific implementation is as follows: a conveyor belt 341 is arranged at the upper end of the frame 34, so that the sludge and other impurities filtered by the vertical filter plate 30 fall onto the conveyor belt 341. At this time, the sludge and other impurities cause the conveyor belt 341 to rotate due to their own gravity, so that the sludge and other impurities falling on the upper end of the frame 34 can be transported to the drop port in time, avoiding the sludge and other impurities from staying at the upper end of the frame 34 after falling on the upper end of the frame 34, resulting in insufficient cleaning of the sludge and other impurities in the sedimentation tank 1.

[0047] In another embodiment provided by the present invention, the crushing knife 39 includes a mounting sleeve 390, the mounting sleeve 390 is arranged outside the mounting shaft 35, a plurality of mounting rods 391 are evenly arranged on the outside of the mounting sleeve 390 along its circumference, a knife 392 is rotatably arranged on the outside of the mounting rod 391, and a torsion spring is arranged between the knife 392 and the mounting rod 391;

[0048] The specific implementation method is as follows: after the separation motor 37 is installed, it drives the crushing knife 39 to rotate and crush the agglomerated sludge and other impurities. When too much sludge and other impurities pass through the crushing knife 39 in a short time, it is difficult for the crushing knife 39 to fully crush them. At this time, in order to avoid the situation where the sludge and other impurities are difficult to pass through the crushing knife 39 and cause sludge blockage, at the same time, the smaller the gap between each cutter 392, the better the crushing effect of agglomerated sludge and other impurities, but the smaller the gap between each cutter 392, the easier it is for the sludge and other impurities at the crushing knife 39 to cause blockage in the accommodation space. In this way, when the sludge and other impurities cause blockage in the installation space 340 where the crushing knife 39 is located, the sludge and other impurities can squeeze the cutter 392, so that the cutter 392 drives the torsion spring to rotate along the mounting rod 391, thereby facilitating the increase of the gap between the twisted cutters 392, so that sludge and other impurities can pass through the mounting space 340 where the crushing cutter 39 is located, so that the sludge and other impurities are crushed by the spiral auger 36 while being transported by the spiral auger 36; when the sludge and other impurities that cause blockage pass through the mounting space 340 where the crushing cutter 39 is located, the torsion spring drives the cutter 392 to rotate on the mounting rod 391, so that the torsion spring drives the cutter 392 to rotate in the opposite direction and reset, thereby restoring the cutter 392 to its original state, so that the gap between the cutters 392 is smaller, so that the cutter 392 can continue to crush the agglomerated sludge and other impurities with better effect.

[0050] The specific implementation is as follows: two rectangular grooves are symmetrically arranged in the sedimentation tank 1, and a screw rod 21 is arranged in each rectangular groove. Each screw rod 21 is arranged parallel to the bottom of the sedimentation tank 1. Two fixed racks are symmetrically arranged in the sedimentation tank 1, and a fixed rack is arranged in each rectangular groove. The driving gear 25 is meshed with the fixed rack. Specifically, after the sewage enters the sedimentation tank 1, the sludge and other impurities in the sewage are precipitated and fall on the bottom inclined surface 10 of the sedimentation tank 1. At this time, the screw rod 21 is driven to rotate by the driving motor 20, so that the screw rod 21 drives the sleeve 24 to move on the screw rod 21. Thereby, the screw rod 21 drives the mounting frame 22 to move through the sleeve 24 and the connecting rod 23. When the mounting frame 22 moves, it moves along the surface of the bottom inclined surface 10 of the sedimentation tank 1, so that the cleaning mechanism can clean the inside of the sedimentation tank 1. When the screw rod 21 drives the sleeve 24 and the connecting rod 23 to move along the screw rod 21, the driving gear 25 and the fixed rack move relative to each other, so that the driving gear 25 can drive the connecting rod 23 to rotate on the mounting frame 22, so that the connecting rod 23 drives the first bevel gear 26 to rotate, so that the first bevel gear 26 drives the cleaning mechanism 27 to rotate and clean the inside of the sedimentation tank 1.

[0052] The specific implementation is as follows: when the driving gear 25 moves along the fixed rack, the driving gear 25 drives the connecting rod 23 to rotate, so that the driving gear 25 drives the first bevel gear 26 to rotate through the connecting rod 23, so that the first bevel gear 26 drives the vertical cleaning roller 270 to rotate on the mounting frame 22 through the second bevel gear 271, so that the rotated vertical cleaning roller 270 can clean the two side walls of the sedimentation tank 1 with rectangular grooves, and while the vertical cleaning roller 270 rotates to clean the interior of the sedimentation tank 1, the vertical cleaning roller 270 can drive the third bevel gear 272 to rotate, so that the third bevel gear 272 drives the pool bottom cleaning roller 273 to rotate through the fourth bevel gear 274, so that the pool bottom cleaning roller 273 cleans the bottom inclined surface of the sedimentation tank 1, so that the vertical cleaning roller 270 and the pool bottom cleaning roller 273 can clean the interior of the sedimentation tank 1 to prevent impurities such as sludge in sewage from staying on the side walls of the sedimentation tank 1 or the bottom inclined surface of the sedimentation tank 1.

[0053] In another embodiment provided by the present invention, the cleaning mechanism 27 further includes a scraper 275, the scraper 275 is located on one side of the pool bottom cleaning roller 273, and the scraper 275 is arranged at a position of the mounting frame 22 facing the separation assembly 3, and an arc plate 276 is arranged at the upper end of the scraper 275, and the arc plate 276 is arranged on the mounting frame 22;

[0054] The specific implementation is as follows: when the bottom inclined surface 10 of the sedimentation tank 1 is cleaned by the bottom cleaning roller 273, sludge and other impurities may adhere to the surface of the bottom inclined surface 10 of the sedimentation tank 1. These stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10 of the sedimentation tank 1 are difficult to be cleaned and removed by the bottom cleaning roller 273. In order to avoid the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10, the screw rod 21 is driven by the driving motor 20 to rotate, so that the screw rod 21 drives the sleeve 24 to move on the screw rod 21, so that the screw rod 21 drives the mounting frame 22 to move along the surface of the bottom inclined surface 10 of the sedimentation tank 1 through the sleeve 24 and the connecting rod 23. When the mounting frame 22 moves, it can drive the scraper 275 to move, so that the scraper 275 can scrape the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10 of the sedimentation tank 1. The scraper 275 is located on one side of the pool bottom cleaning roller 273 and is closer to the separation component 3. In this way, when cleaning the sludge and other impurities in the sedimentation tank 1, the driving motor 20 drives the connecting rod 23 and the mounting frame 22 to move along the bottom inclined surface 10 of the sedimentation tank 1 through the screw rod 21 and the sleeve 24, so that the mounting frame 22 drives the scraper 275 to first scrape off the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10, and then the pool bottom cleaning roller 273 cleans the surface of the bottom inclined surface 10 after the sludge is scraped off; when the scraper 275 scrapes off the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10, the arc plate 276 provided at the upper end of the scraper 275 is used to shield and isolate the scraped sludge and other impurities to prevent the scraped sludge and other impurities from adhering to the mounting frame 22.

[0058] The specific implementation is as follows: after sludge and other impurities enter the retention space 41, the sludge and other impurities will adhere to the inner wall of the retention space 41. In this way, when the sludge pump 40 transports the sludge and other impurities to the conveying pipe 43 through the fixed pipe 42, the sludge and other impurities will drive the propeller blades 45 to rotate during the process of passing through the fixed pipe 42, so that the propeller blades 45 drive the vertical rod 44 to rotate in the fixed pipe 42, so that the vertical rod 44 drives the multiple L-shaped scrapers 46 evenly arranged around it to rotate, so that the rotating multiple L-shaped scrapers 46 stir the sludge and other impurities in the retention space 41 to prevent the sludge and other impurities from settling and agglomerating.

[0059] Working principle: After the sewage enters the sedimentation tank 1, it is allowed to stand for a period of time, so that the sludge and other impurities in the sewage are settled at the bottom of the sedimentation tank 1. After the sludge and other impurities in the sewage are settled, the screw rod 21 is driven to rotate by the driving motor 20, so that the screw rod 21 drives the sleeve 24 to move on the screw rod 21, so that the screw rod 21 drives the mounting frame 22 to move through the sleeve 24 and the connecting rod 23. When the mounting frame 22 moves, it moves along the surface of the bottom inclined surface 10 of the sedimentation tank 1, which is convenient for the cleaning mechanism to clean the inside of the sedimentation tank 1. When the screw rod 21 drives the sleeve 24 and the connecting rod 23 to move along the screw rod 21, the driving gear 25 and the fixed rack move relative to each other, so that the driving gear 25 can drive the connecting rod 23 to rotate on the mounting frame 22. , so that the connecting rod 23 drives the first bevel gear 26 to rotate, so that the first bevel gear 26 drives the vertical cleaning roller 270 to rotate on the mounting frame 22 through the second bevel gear 271, so that the rotated vertical cleaning roller 270 can clean the two side walls of the sedimentation tank 1 with the rectangular groove, and while the vertical cleaning roller 270 rotates to clean the interior of the sedimentation tank 1, the vertical cleaning roller 270 can drive the third bevel gear 272 to rotate, so that the third bevel gear 272 drives the pool bottom cleaning roller 273 to rotate through the fourth bevel gear 274, so that the pool bottom cleaning roller 273 cleans the bottom inclined surface of the sedimentation tank 1, so that the vertical cleaning roller 270 and the pool bottom cleaning roller 273 can clean the interior of the sedimentation tank 1, avoiding The sludge and other impurities in the sewage are prevented from staying on the side wall of the sedimentation tank 1 or the bottom inclined surface of the sedimentation tank 1; when the bottom inclined surface 10 of the sedimentation tank 1 is cleaned by the pool bottom cleaning roller 273, in order to prevent the sludge and other impurities from adhering to the surface of the bottom inclined surface 10 of the sedimentation tank 1, the screw rod 21 is driven to rotate by the driving motor 20, so that the screw rod 21 drives the sleeve 24 to move on the screw rod 21, so that the screw rod 21 drives the mounting frame 22 to move along the surface of the bottom inclined surface 10 of the sedimentation tank 1 through the sleeve 24 and the connecting rod 23, and when the mounting frame 22 moves, it can drive the scraper 275 to move, so that the scraper 275 can scrape off the stubborn sludge and other impurities adhering to the surface of the bottom inclined surface 10 of the sedimentation tank 1, and the scraper 275 is on the pool bottom cleaning roller 273. One side and closer to the separation component 3, so that when cleaning the sludge and other impurities in the sedimentation tank 1, the driving motor 20 drives the connecting rod 23 and the mounting frame 22 to move along the bottom inclined surface 10 of the sedimentation tank 1 through the screw rod 21 and the sleeve 24, so that the mounting frame 22 drives the scraper 275 to first scrape off the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10, and then the bottom cleaning roller 273 cleans the surface of the bottom inclined surface 10 after the sludge is scraped off; when the scraper 275 scrapes off the stubborn sludge and other impurities adhered to the surface of the bottom inclined surface 10, the arc plate 276 provided at the upper end of the scraper 275 is used to shield and isolate the scraped sludge and other impurities to prevent the scraped sludge and other impurities from adhering to the mounting frame 22;

[0060] The driving motor 20 drives the screw rod 21 to rotate so that the sleeve 24 moves on the screw rod 21, so that the screw rod 21 drives the mounting frame 22 to move along the bottom inclined surface 10 of the sedimentation tank 1 through the sleeve 24 and the connecting rod 23. When the mounting frame 22 moves close to the vertical filter plate 30, the sludge and other impurities scraped off by the scraper 275, the vertical cleaning roller 270 and the pool bottom cleaning roller 273 are pushed toward the vertical filter plate 30, so that the vertical filter plate 30 first filters and cleans the sludge and other impurities, thereby collecting the sludge and other impurities with too large particles into the containing part 300, and when the mounting frame 22 approaches the vertical filter plate 30, it drives the two moving racks 32 located on both sides of the mounting frame 22 to move toward the roller column 31, so that the two moving racks 32 can approach and align with the rollers 31. The two rotating gears 33 at the two ends are meshed respectively, and the two moving racks 32 are meshed with the two rotating gears 33 respectively. After the mounting frame 22 continues to approach the roller 31, the two moving racks 32 drive the roller 31 to rotate through the two rotating gears 33, so that the lever 310 provided on the outside of the roller 31 pushes the sludge and other impurities at the bottom of the sedimentation tank 1 to the containing part 300, and at the same time, the material-pickling wire 3000 provided on the inside of the containing part 300 is convenient for scraping off the sludge and other impurities on the lever 310 and leaving them in the containing part 300, so that the larger impurities are filtered and left in the containing part 300, and the smaller impurities fall to the upper end of the frame 34 through the vertical filter plate 30, and when there are more impurities in the containing part 300 or the sludge and other impurities in the sedimentation tank 1 are processed, After completion, the pull rod 301 is pulled upward, so that the pull rod 301 pulls the multiple steel wire ropes 302 at the same time, so that the multiple steel wire ropes 302 squeeze the return spring 303 and pull the lower end of the containing part 300 toward the upper end of the containing part 300, that is, the pulling rod 301 can close the opening of the containing part 300 through the multiple steel wire ropes 302, and at this time, the vertical filter plate 30 is drawn out of the sedimentation tank 1 and the sludge and other garbage in the containing part 300 are cleaned; in addition, the sludge and other impurities with smaller particles pass through the vertical filter plate 30 and fall on the upper end of the frame 34, and the sludge and other impurities falling on it are inclined at the upper end of the frame 34 so that the sludge and other impurities falling thereon fall from the drop opening into the installation space 340, and at this time, the separation motor 37 drives the installation shaft 35 to rotate, so that the installation shaft 35 carries The movable spiral auger 36 rotates, so that the spiral auger 36 transports the sludge and other impurities that fall into the installation space 340 to the conveying component 4, and when the sludge and other impurities are transported by the conveying component 4, the separation motor 37 drives the crushing knife 39 to rotate through the installation shaft 35 so that the crushing knife 39 rotates and crushes the sludge and other impurities. At the same time, the spiral auger 36 can also rotate and crush the sludge and other impurities, so that the particles of the sludge and other impurities are crushed and smaller, which is convenient for the spiral auger 36 to transport the sludge and other impurities to the conveying component 4, and convenient for the conveying component 4 to suck the sludge and other impurities to the outside of the sedimentation tank 1; the sealing plate 38 is used to separate the sludge and other impurities from the separation motor 37, so as to avoid the separation motor 37 from contacting the sludge and other impurities, causing damage or shortening the service life;When the separation motor 37 is installed and drives the crushing blade 39 to rotate and crush the agglomerated sludge and other impurities, when too much sludge and other impurities pass through the crushing blade 39 in a short time, it is difficult for the crushing blade 39 to fully crush them. At this time, in order to avoid the situation where the sludge and other impurities are difficult to pass through the crushing blade 39 and cause sludge blockage, at the same time, the smaller the gap between each cutter 392, the better the crushing effect of agglomerated sludge and other impurities, but the smaller the gap between each cutter 392, the easier it is for the sludge and other impurities at the crushing blade 39 to cause clogging of the accommodation space. In this way, when the sludge and other impurities cause clogging of the installation space 340 where the crushing blade 39 is located, the sludge and other impurities can squeeze the cutter 392, so that the cutter 392 can move The dynamic torsion spring rotates along the mounting rod 391, so that the gap between the twisted cutters 392 is increased, so that sludge and other impurities can pass through the mounting space 340 where the crushing cutter 39 is located, so that the sludge and other impurities are crushed by the spiral auger 36 while being transported by the spiral auger 36; when the sludge and other impurities that cause blockage pass through the mounting space 340 where the crushing cutter 39 is located, the torsion spring drives the cutter 392 to rotate on the mounting rod 391, so that the torsion spring drives the cutter 392 to rotate in the opposite direction and reset, so that the cutter 392 returns to its original state, so that the gap between the cutters 392 is smaller, so that the cutter 392 can continue to crush the agglomerated sludge and other impurities with a better effect;

[0061] The separation motor 37 drives the installation shaft 35 to rotate, so that the installation shaft 35 drives the spiral auger 36 to rotate, so that the spiral auger 36 transports the sludge and other impurities that fall into the installation space 340 to the retention space 41. After the sludge and other impurities enter the retention space 41, the sludge pump 40 works so that the sludge and other impurities are sucked into the sludge pump 40 by the fixed pipe 42, and the sludge pump 40 transports the sludge and other impurities to the conveying pipe 43, so that the conveying pipe 43 transports the sludge and other impurities from the sedimentation tank 1 to the outside of the sedimentation tank 1; and after the sludge and other impurities enter the retention space 41, the sludge and other impurities will adhere to the inner wall of the retention space 41, In this way, when the sludge pump 40 transports sludge and other impurities to the conveying pipe 43 through the fixed pipe 42, the sludge and other impurities will drive the propeller blades 45 to rotate in the process of passing through the fixed pipe 42, so that the propeller blades 45 drive the vertical rod 44 to rotate in the fixed pipe 42, so that the vertical rod 44 drives the multiple L-shaped scrapers 46 evenly arranged on its circumference to rotate, so that the rotating multiple L-shaped scrapers 46 stir the sludge and other impurities in the retention space 41 to prevent the sludge and other impurities from settling and agglomerating. At the same time, the rotating multiple L-shaped scrapers 46 can scrape the inner wall of the retention space 41 to prevent the sludge and other impurities from sticking to the inner wall of the retention space 41.
