Description

Technical Field

[0001] This invention belongs to the field of sludge treatment technology, specifically relating to a toxic sludge purification and treatment device and method. Background Technology

[0002] A sludge scraper is a machine used to remove sludge from riverbeds. It is used in large-diameter circular sedimentation tanks in urban sewage treatment plants, waterworks, and industrial wastewater treatment plants to remove sludge settled at the bottom and skim off scum from the surface. Sludge scrapers are mainly divided into peripheral drive scrapers and center drive thickening scrapers. A center drive thickening scraper mainly consists of an overflow device, main beam and railings, inlet pipe, transmission device, electrical box, flow stabilizer, main shaft, scum rake, scraping device, underwater bearing, small scraper, scum hopper, and scum rake. The center drive thickening scraper can further separate free water from the sludge in the thickening tank to reduce the sludge volume, increase the sludge concentration, and discharge the thickened sludge out of the tank.

[0003] Existing sludge scrapers typically use water pumps to directly pump sludge into sedimentation tanks. During the pumping process, water is drawn into the sedimentation tank along with the sludge. After the sludge settles, it is scraped to the discharge outlet for discharge. However, existing sludge scrapers lack a sludge filtration structure. This means that when the water pump draws the sludge into the sedimentation tank, larger impurities in the sludge are also discharged along with it, easily causing blockages at the bottom of the sedimentation tank and hindering efficient sludge discharge. Summary of the Invention

[0004] The purpose of this invention is to provide a toxic sludge purification and treatment device and method, which aims to solve the problem that the existing sludge scraper does not have a sludge filtration structure. This means that when the water pump pumps the sludge into the sedimentation tank, larger impurities in the sludge will also be discharged into the sedimentation tank along with the sludge, which can easily lead to blockage at the bottom of the sedimentation tank and make it difficult to discharge the sludge effectively.

[0077] The second belt is connected between the circumferential surfaces of the two second I-beam pulleys.

[0078] A method for purifying and treating toxic sludge includes the following steps:

[0079] S1. First, connect the water pump discharge pipe to the sludge inlet hole so that the water pump draws the sludge into the filter box. The sludge slides along the bottom of the filter box, so that the sludge and water are filtered out through the first filter hole and enter the sedimentation tank. Large debris slides along the bottom wall of the filter box and falls onto the top of the filter plate.

[0080] S2. At this time, the motor is started. The output end of the motor drives the second bevel gear to rotate. The second bevel gear drives the third shaft to rotate through oblique meshing with the first bevel gear. The third shaft drives the third bevel gear and one of the second I-beams to rotate. Through oblique meshing with the third bevel gear and the fourth bevel gear, the fourth shaft rotates. The fourth shaft drives one of the first I-beams to rotate. Through the transmission of the first belt, the other first I-beam drives the first shaft to rotate. The first shaft drives the arc-shaped block on its surface to rotate through the hollow column. The arc-shaped block intermittently abuts against one end of the lever plate. Since the lever plate is fixed to the surface of the second shaft, the second shaft can rotate. When one end of the lever plate is intermittently abutted, the lever plate performs lever movement. The other end drives the rubber block to intermittently knock the bottom of the filter box, causing the filter box to vibrate. This allows the sludge, water and large debris flowing on the bottom wall of the filter box to slide or be filtered down better, and are less likely to remain on the bottom wall of the filter box.

[0081] S3. Simultaneously, when the fourth rotating shaft rotates, it can drive the turntable to rotate. Since one end of the connecting rod is fixed to the edge of the turntable, the rotation of the turntable causes one end of the connecting rod to make an eccentric movement, which causes one end of the connecting rod to move the slide plate. The slide plate is slidably connected to the T-shaped groove through the T-shaped block, which limits the position of the slide plate. Therefore, the slide plate makes a linear up-and-down movement. The slide plate drives the rack to make a linear reciprocating movement. The rack drives the lead screw to make a forward and reverse reciprocating movement through the gear meshing with it. Since the nut block matches the interior of the hollow seat, when the lead screw makes a forward and reverse movement, it drives the nut block to make a reciprocating linear movement. The nut block drives the filter plate to move laterally and reciprocally through the connecting slider, so that large debris falling into the surface of the filter plate can slide better onto the conveyor belt. At the same time, the filter holes on the filter plate can also filter out the sludge and water that slides down from the bottom wall of the filter box.

[0082] S4. At the same time, when one of the second I-beams rotates, it drives the other second I-beam to rotate through the transmission of the second belt, so that one of the transmission rollers rotates. Since the transmission belt drives between the surfaces of the two transmission rollers, the other transmission roller also rotates. At the same time, the transmission belt can carry large debris that falls on its top to the outside of the sedimentation tank for collection, so that it will not fall into the sedimentation tank and avoid clogging of the sludge discharge pipe.

[0083] S5. The motor output can also drive the drive pinion to rotate, which in turn drives the driven gear. Due to the different transmission ratios of the drive pinion and the driven gear, the driven gear speed decreases, causing the rotating rod to rotate slowly. The rotating rod drives the scraper through the crossbar to scrape the sludge at the bottom of the sedimentation tank, causing the sludge to fall into the sludge discharge hopper for easy discharge. At the same time, after the water pump finishes pumping the sludge, the motor can be stopped. After the sedimentation tank has settled, the motor can be restarted so that the multiple scrapers can better scrape the bottom wall of the sedimentation tank for better sludge cleaning.

[0084] Compared with the prior art, the beneficial effects of the present invention are:

[0085] 1. In this solution, the filter box is installed so that when the water pump pumps the sludge into the sedimentation tank, larger debris can be blocked by the filter box and slide from its surface to the filter plate. At the same time, the sludge and water enter the sedimentation tank, preventing larger debris from entering the sedimentation tank. This makes it less likely for the sludge discharge pipe at the bottom of the sedimentation tank to be blocked, and allows for better sludge cleaning.

[0086] 2. In this solution, the intermittent vibration mechanism intermittently contacts the bottom of the filter box, causing the filter box to vibrate. This makes it less likely for sludge, water, and debris falling onto the bottom wall of the filter box to remain on the bottom wall. Instead, they are better filtered out or slid off, making it less likely to leave residue.

[0087] 3. In this solution, the filter plate allows larger debris to slide slowly onto the conveying mechanism, preventing it from spilling outwards due to excessive impact. At the same time, the reciprocating circulation mechanism allows the filter plate to sway back and forth, ensuring that large debris on its surface falls smoothly into the conveying mechanism. Furthermore, the sludge and water sliding from the filter box onto the filter plate can be filtered a second time, passing through the second filter holes and preventing them from spilling outside the sedimentation tank.

[0088] 4. In this scheme, the conveyor belt in the conveying mechanism extends outward from the sedimentation tank at a small angle, so that large debris falling onto the surface of the conveyor belt can be conveyed to the outside of the sedimentation tank, while the water on the surface of the conveyor belt can flow down the surface of the conveyor belt into the sedimentation tank.

[0089] 5. In this solution, the provided drive mechanism can drive multiple mechanisms of the device to move, realizing single drive without the need for multiple drives, reducing the existence of drive equipment, saving power consumption and reducing resource utilization, and has broad application prospects.

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.

[0105] Example 1

[0106] Please see Figures 1-12 The present invention provides the following technical solutions:

[0107] A toxic sludge purification and treatment device includes a sludge scraping device and a sterilization and purification device, wherein the sludge scraping device includes:

[0108] Overpass 1;

[0109] Sedimentation tank 2 is located on the underside of overhead bridge slab 1;

[0110] Sludge discharge hopper 202 is fixed to the bottom of sedimentation tank 2;

[0111] Sludge discharge pipe 203, which fixes the bottom of sludge discharge hopper 202 and is connected to sludge discharge hopper 202;

[0112] A sludge scraping mechanism is installed inside the sedimentation tank 2 to discharge the settled sludge;

[0113] The filter box 5 is fixed to the bottom of the bridge plate 1, and the bottom of the filter box 5 is inclined.

[0114] The mud inlet hole 103 is located at the top of the bridge plate 1 and is connected to the filter box 5;

[0115] The first filter hole 501 has multiple holes, all of which are opened at the bottom of the filter box 5;

[0116] An intermittent vibration mechanism is connected to the filter box 5 to intermittently tap the bottom of the filter box 5;

[0117] Filter plate 26 is located on the lower side of the lower edge of filter box 5;

[0118] The second filter hole 27 has multiple holes, all of which are opened at the bottom of the filter plate 26;

[0119] A reciprocating circulation mechanism is connected to the filter plate 26 to enable it to perform reciprocating circulation motion;

[0120] A conveying mechanism is installed on one side of the filter plate 26 to transfer impurities to the outside of the sedimentation tank 2;

[0121] A drive mechanism is installed on sedimentation tank 2 to drive the operation of the equipment;

[0122] The sterilization and purification device includes:

[0123] Purification liquid storage tank 46 is fixed to the top of the overhead bridge plate 1;

[0124] Two liquid inlet hoppers 461 are provided, which are symmetrically fixed on the top two sides of the purification liquid storage tank 46 and communicate with the interior of the purification liquid storage tank 46.

[0125] The drain pipe 471 is located at the bottom of the purified liquid storage tank 46, and the drain pipe 471 extends through to the bottom of the bridge plate 1 and downwards.

[0126] A sealing mechanism is provided on top of the purification liquid storage tank 46 to seal the two inlet hoppers 461.

[0127] In a specific embodiment of the present invention, when this device is in use, the overpass 1 is used for people to walk on. Guardrails 101 are fixed to both sides of the top of the overpass 1 to protect pedestrians. Steps 102 are fixed to both the left and right sides of the overpass 1 to support the overpass 1. The top of the sludge discharge hopper 202 is open and rests on the bottom of the sedimentation tank 2. Multiple evenly distributed overflow holes 201 are provided on the surface of the sedimentation tank 2. When there is a lot of water, it overflows from the overflow holes 201. The bottom wall of the sedimentation tank 2 is inclined. The sludge discharge pipe 203 is connected to the sludge discharge hopper 202 for discharging sludge. A valve 2031 is also installed on the sludge discharge pipe 203 to control its flow. A sludge scraping mechanism is installed inside the sedimentation tank 2 to scrape the sludge from the sedimentation tank 2 into the sludge discharge hopper 202, and finally discharge it through the sludge discharge pipe 203. The sludge entering the sedimentation tank 2 is pumped from the river by a water pump, and water and larger debris are also pumped out, flowing into the filter box 5 through the sludge inlet 103. The first filter hole 501 allows water to pass through. After the sludge and sludge are filtered through the first filter hole 501, larger impurities slide down the inclined bottom wall of the filter box 5 onto the filter plate 26. The intermittent vibration mechanism intermittently abuts against the bottom of the filter box 5, causing the filter box 5 to vibrate. This prevents sludge, water, and impurities falling onto the bottom wall of the filter box 5 from remaining on the bottom wall, allowing them to be filtered out or slide down more easily, reducing residue. The filter plate 26 is inclined downwards at a small angle to buffer the sliding larger impurities. At the same time, the reciprocating circulation mechanism can... The filter plate 26 is moved back and forth slightly, allowing larger debris on the top of the filter plate 26 to slide down its surface to the conveying mechanism. Baffles are provided on both sides of the filter plate 26 to prevent larger debris from sliding out from the sides. This allows the filter plate 26 to be conveyed to the outside of the sedimentation tank 2 more effectively, preventing blockage of the sludge discharge pipe 203. Furthermore, the sludge and water that slide from the filter box 5 onto the filter plate 26 can be filtered a second time and filtered down through the second filter hole 27, preventing them from spilling outside the sedimentation tank 2.

[0128] Specifically, in the sterilization and purification device, the purification liquid storage tank 46 is used to hold the liquid that sterilizes and purifies the sludge, such as chlorine (Cl) solution or hydrogen peroxide (H2O) solution. Chlorine dissolves in water and undergoes a chemical reaction to generate hypochlorous acid (HClO) and hydrochloric acid (HCl). Hypochlorous acid has strong oxidizing properties and can destroy the cell structure of bacteria and microorganisms, thereby achieving the purpose of sterilization. In sludge treatment, the amount of chlorine added needs to be determined according to factors such as the nature of the sludge and the content of microorganisms. The amount of available chlorine added may be between tens of milligrams per liter and hundreds of milligrams per liter.

[0129] Hydrogen peroxide (HO) solution: Hydrogen peroxide has strong oxidizing properties. It can decompose to produce hydroxyl radicals (ΘH). These free radicals can attack the cell membranes, proteins, nucleic acids, and other biomolecules of microorganisms, leading to the death of microorganisms. The concentration of hydrogen peroxide can be selected according to the degree of sludge pollution and treatment requirements, generally around 3%-30%.

[0130] Liquid can be injected into the purification liquid storage tank 46 through two inlet hoppers 461, or different liquids can be injected and mixed. The two inlet hoppers 461 allow for more efficient and rapid liquid addition. A level gauge 470 is also installed on the purification liquid storage tank 46, with its bottom embedded in the inner wall of the tank. This allows for the measurement of the liquid added to the storage tank 46 and real-time monitoring of the liquid added to the sedimentation tank 2. The liquid flows into the sedimentation tank 2 through the drain pipe 471, which is equipped with an electric control valve 472. The valve 472 is connected to an external control terminal to remotely control the opening and closing of the drain pipe 471, enabling automatic liquid dispensing. This allows the sterilizing and purifying liquid to effectively purify the sludge in the sedimentation tank 2. After injection, the two inlet hoppers 461 can be sealed by a sealing mechanism to prevent liquid evaporation or accidental contact.

[0131] Specifically, the sealing mechanism includes a horizontal handle 463, a sliding rod 464, a sliding sleeve 465, a movable hole 466, a limiting groove 467, a spring 468, a limiting strip 469, and two cover plates 462. The sliding sleeve 465 is fixed to the top of the purified liquid storage tank 46. The movable hole 466 is opened on the top of the sliding sleeve 465. One end of the spring 468 is fixed to the bottom wall of the sliding sleeve 465, and the other end is fixed to the sliding rod 464. The sliding rod 464 is slidably connected in the movable hole 466. The sliding rod 464 consists of two sections. The upper section can rotate. The horizontal handle 463 is fixed to the upper section of the slide rod 464. Two cover plates 462 are fixed to both ends of the horizontal handle 463 and match the liquid inlet 461. Two limiting grooves 467 are provided, symmetrically opened on the inner walls of both sides of the sliding sleeve 465. Two limiting strips 469 are provided, symmetrically fixed on both sides of the circumferential surface of the slide rod 464, and the two limiting strips 469 are slidably connected in the two limiting grooves 467 to limit the movement of the slide rod 464. The sliding motion within the hole 466 is linear and cannot disengage from the sliding sleeve 465. The horizontal handle 463 can rotate based on the upper part of the sliding rod 464. When it is necessary to open the inlet hopper 461, the horizontal handle 463 is lifted upwards. The horizontal handle 463 drives the two cover plates 462 to move upwards and disengage from the inlet hopper 461. At the same time, the sliding rod 464 is driven to slide upwards within the movable hole 466, stretching the spring 468. Then, the horizontal handle 463 is rotated, causing the inlet hopper 461 and the cover plates 462 to misalign. The horizontal handle 463 is then released. 3. The spring 468's elasticity causes the horizontal handle 463 to return to its original position, at which point the inlet hopper 461 is open. When the liquid filling is complete and the inlet hopper 461 needs to be closed, pull the horizontal handle 463 upwards again and select the position so that the cover plate 462 is aligned with the inlet hopper 461. Release the horizontal handle 463, and the spring 468's elasticity causes the cover plate 462 to return to its original position and embed into the inlet hopper 461 to achieve a seal on the inlet hopper 461. Preferably, the circumferential surface of the cover plate 462 is wrapped with a rubber sleeve to achieve a better sealing effect.

[0132] Specifically, intermittent vibration mechanisms include:

[0133] The second fixing plate 16 is provided in two parts, both of which are fixed to the bottom of the overpass plate 1;

[0134] Two first fixing plates 6 are provided, and the two first fixing plates 6 are fixed between the adjacent ends of the two second fixing plates 16;

[0135] The second rotating shaft 13 is rotatably connected between the adjacent ends of the two second fixed plates 16;

[0136] Lever plate 14 is fixed to the circumferential surface of the second rotating shaft 13;

[0137] Rubber block 15 is fixed to one end surface of lever plate 14 near filter box 5, and rubber block 15 intermittently abuts against the bottom of filter box 5;

[0138] The first rotating shaft 7 is rotatably connected to the near ends of the two first fixed plates 6;

[0139] Hollow column 8 is fixed to the circumferential surface of the first rotating shaft 7;

[0140] The arc-shaped block 9 is fixed to the circumferential surface of the hollow column 8 and intermittently abuts against the top of one side of the lever plate 14.

[0141] In this embodiment: the first rotating shaft 7 rotates, and the first rotating shaft 7 drives the arc-shaped block 9 on its surface to rotate through the hollow column 8, so that the arc-shaped block 9 intermittently abuts against one end of the lever plate 14. Since the lever plate 14 is fixed to the surface of the second rotating shaft 13, the second rotating shaft 13 can rotate, so that when one end of the lever plate 14 is intermittently abutted, the lever plate 14 performs lever movement, and the other end drives the rubber block 15 to intermittently knock the bottom of the filter box 5, causing the filter box 5 to vibrate, so that the sludge, water and large debris flowing on the bottom wall of the filter box 5 can slide or be filtered down better, and are not easy to remain on the bottom wall of the filter box 5.

[0142] Specifically, a stop bar 12 is fixed between the adjacent ends of the two second fixing plates 16, and the stop bar 12 is located on the upper side of the end of the lever plate 14 away from the filter box 5.

[0143] In this embodiment: Since one end of the lever plate 14 includes a rubber block 15, under the action of gravity, the end of the lever plate 14 with the rubber block 15 will droop down, and the other end will be raised and abut against the stop bar 12, and will not contact the surface of the hollow column 8. However, when the hollow column 8 rotates, it drives the arc block 9 to rotate, which can make the arc block 9 abut against the lever plate 14, so that the lever plate 14 performs lever movement. In this way, the hollow column 8 will not be in contact with the lever plate 14 for a long time, and is not easy to wear.

[0144] Specifically, the reciprocating mechanism includes:

[0145] The fourth fixing plate 28 is fixed to the bottom of the overpass plate 1;

The water and sludge are filtered down by the second filter hole 27, while large debris slides down the surface of the filter plate 26 to the conveying mechanism.

[0157] Specifically, a T-shaped groove 31 is provided at the bottom of the fourth fixing plate 28, and a T-shaped block 32 is slidably connected in the T-shaped groove 31. The T-shaped block 32 is fixed to the end of the slide plate 33 that is close to each other.

[0191] Example 2

[0192] This embodiment 2 also provides a method for purifying and treating toxic sludge, which further elaborates and explains the working principle and implementation method of the above embodiment 1, as follows:

[0193] A method for purifying and treating toxic sludge includes the following steps:

[0194] S1. First, connect the water pump discharge pipe to the mud inlet 103 so that the water pump draws the sludge into the filter box 5. The sludge slides along the bottom of the filter box 5, so that the sludge and water are filtered out from the first filter hole 501 and enter the sedimentation tank 2. Large debris slides along the bottom wall of the filter box 5 and falls onto the top of the filter plate 26.

[0195] S2. At this time, motor 3 is started. The output end of motor 3 drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the third shaft 18 to rotate through oblique meshing with the first bevel gear 19. The third shaft 18 drives the third bevel gear 43 and one of the second I-beam pulleys 37 to rotate. Through oblique meshing between the third bevel gear 43 and the fourth bevel gear 44, the fourth shaft 36 rotates. The fourth shaft 36 drives one of the first I-beam pulleys 10 to rotate. Through the transmission of the first belt 11, the other first I-beam pulley 10 drives the first shaft 7 to rotate. The first rotating shaft 7 drives the arc-shaped block 9 on its surface to rotate through the hollow column 8, so that the arc-shaped block 9 intermittently abuts against one end of the lever plate 14. Since the lever plate 14 is fixed to the surface of the second rotating shaft 13, the second rotating shaft 13 can rotate, so that when one end of the lever plate 14 is intermittently abutted, the lever plate 14 performs lever movement, and the other end drives the rubber block 15 to intermittently knock the bottom of the filter box 5, causing the filter box 5 to vibrate, so that the sludge, water and large debris flowing on the bottom wall of the filter box 5 can slide or be filtered down better, and are less likely to remain on the bottom wall of the filter box 5.

[0196] S3. Simultaneously, when the fourth rotating shaft 36 rotates, it can drive the turntable 29 to rotate. Since one end of the connecting rod 30 is fixed to the edge of the turntable 29, the rotation of the turntable 29 causes one end of the connecting rod 30 to make an eccentric movement, which in turn causes one end of the connecting rod 30 to move the slide plate 33. The slide plate 33 is slidably connected to the T-slot 31 through the T-block 32, which limits the position of the slide plate 33. Therefore, the slide plate 33 makes a vertical linear motion, and the slide plate 33 drives the rack 34 to make a linear reciprocating motion. 34 drives the lead screw 23 to reciprocate in both directions through the meshing gear 35. Since the nut block 24 matches the interior of the hollow seat 21, the lead screw 23 drives the nut block 24 to reciprocate in a linear motion when it rotates in both directions. The nut block 24 drives the filter plate 26 to swing laterally through the connecting slider 25, so that large debris falling onto the surface of the filter plate 26 can slide better onto the conveyor belt 41. At the same time, the filter holes on the filter plate 26 can also filter out the sludge and water that slides off the bottom wall of the filter box 5.

[0197] S4. At the same time, when one of the second I-beam pulleys 37 rotates, it drives the other second I-beam pulley 37 to rotate through the transmission of the second belt 38, so that one of the transmission rollers 40 rotates. Since the transmission belt 41 drives between the surfaces of the two transmission rollers 40, the other transmission roller 40 also rotates. At the same time, the transmission belt 41 can carry large debris falling on its top to the outside of the sedimentation tank 2 for collection, so that it will not fall into the sedimentation tank 2, thus avoiding blockage of the sludge discharge pipe 203. After the sludge is collected in the sedimentation tank 2, the liquid in the purification liquid storage tank 46 is added to the sedimentation tank 2 to achieve sterilization and purification of the sludge.

[0198] S5. The output of motor 3 can also drive the drive pinion 301 to rotate. The drive pinion 301 drives the driven gear 302. Due to the different transmission ratios of the drive pinion 301 and the driven gear 302, the speed of the driven gear 302 is reduced, causing the rotating rod 4 to rotate slowly. The rotating rod 4 drives the scraper 402 through the crossbar 401 to scrape the sludge at the bottom of the sedimentation tank 2, so that the sludge falls into the sludge discharge hopper 202 for easy discharge. At the same time, after the water pump finishes pumping the sludge, the operation of motor 3 can be stopped. After the sedimentation tank 2 has settled, motor 3 can be restarted so that multiple scrapers 402 can better scrape the bottom wall of the sedimentation tank 2 to achieve better sludge cleaning.

[0199] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

9. A method for purifying and treating toxic sludge, characterized in that, When applied to a toxic sludge purification and treatment device as described in claim 8, the method includes the following steps: S1. First, connect the water pump discharge pipe to the mud inlet hole (103) so that the water pump draws the sludge into the filter box (5). The sludge slides along the bottom of the filter box (5) so that the sludge and water are filtered out from the first filter hole (501) and enter the sedimentation tank (2). Large debris slides along the bottom wall of the filter box (5) and falls into the top of the filter plate (26). S2. At this time, the motor (3) is started. The output end of the motor (3) drives the second bevel gear (20) to rotate. The second bevel gear (20) drives the third shaft (18) to rotate through the oblique meshing with the first bevel gear (19). The third shaft (18) drives the third bevel gear (43) and one of the second I-beams (37) to rotate. Through the oblique meshing of the third bevel gear (43) and the fourth bevel gear (44), the fourth shaft (36) rotates. The fourth shaft (36) drives one of the first I-beams (10) to rotate. Through the transmission of the first belt (11), the other first I-beam (10) drives the first shaft (7) to rotate. When the first rotating shaft (7) rotates, the arc-shaped block (9) on its surface rotates through the hollow column (8), so that the arc-shaped block (9) intermittently abuts against one end of the lever plate (14). Since the lever plate (14) is fixed to the surface of the second rotating shaft (13), the second rotating shaft (13) can rotate, so that when one end of the lever plate (14) is intermittently abutted, the lever plate (14) performs lever movement, and the other end drives the rubber block (15) to intermittently knock on the bottom of the filter box (5), so that the filter box (5) vibrates, thereby allowing the sludge, water and large debris flowing on the bottom wall of the filter box (5) to slide or be filtered down better, and not easily remain on the bottom wall of the filter box (5); S3. Simultaneously, when the fourth rotating shaft (36) rotates, it can drive the turntable (29) to rotate. Since one end of the connecting rod (30) is fixed at the edge of the turntable (29), when the turntable (29) rotates, it drives one end of the connecting rod (30) to make an eccentric movement, causing one end of the connecting rod (30) to drive the slide plate (33) to move. The slide plate (33) is slidably connected to the T-slot (31) through the T-block (32), so that the position of the slide plate (33) is limited. Therefore, the slide plate (33) makes a vertical linear motion. The slide plate (33) drives the rack (34) to make a linear reciprocating motion. The bar (34) drives the lead screw (23) to reciprocate in both directions through the gear (35) meshing with it. Since the nut block (24) matches the interior of the hollow seat (21), the lead screw (23) drives the nut block (24) to reciprocate in a linear motion when it rotates in both directions. The nut block (24) drives the filter plate (26) to swing laterally through the connecting slider (25), so that large debris falling on the surface of the filter plate (26) can slide better onto the conveyor belt (41). At the same time, the filter holes on the filter plate (26) can also filter out the sludge and water that slides off the bottom wall of the filter box (5). S4. At the same time, when one of the second I-beams (37) rotates, it drives the other second I-beam (37) to rotate through the transmission of the second belt (38), so that one of the transmission rollers (40) rotates. Since the transmission belt (41) is driven between the surfaces of the two transmission rollers (40), the other transmission roller (40) also rotates. At the same time, the transmission belt (41) can carry the large debris that falls on its top to the outside of the sedimentation tank (2) for collection. It will not fall into the sedimentation tank (2) and avoid clogging of the sludge discharge pipe (203). S5. The output end of the motor (3) can also drive the drive pinion (301) to rotate. The drive pinion (301) drives the driven gear (302). Due to the different transmission ratios of the drive pinion (301) and the driven gear (302), the speed of the driven gear (302) is reduced, which drives the rotating rod (4) to rotate slowly. The rotating rod (4) drives the scraper (402) through the crossbar (401) to scrape the sludge at the bottom of the sedimentation tank (2), so that the sludge falls into the sludge discharge hopper (202) for easy discharge. At the same time, after the water pump finishes pumping the sludge, the operation of the motor (3) can be stopped. After the sedimentation tank (2) has settled, the motor (3) can be restarted so that the multiple scrapers (402) can better scrape the bottom wall of the sedimentation tank (2) to achieve better sludge cleaning.
