Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a wastewater treatment device capable of treating flocculent materials. Background Technology

[0002] With my country's continuous economic development and rising living standards, people are paying increasing attention to environmental protection. Water, hailed as the source of life, requires purification of wastewater generated from household, commercial, and industrial sources, necessitating wastewater treatment equipment. Industrial wastewater often contains large amounts of flocculent matter, which can clog the filters in wastewater treatment equipment. Existing wastewater treatment systems typically use filters to remove this flocculent matter. However, this method can lead to filter clogging over time, reducing treatment speed. Furthermore, prolonged contact between flocculent matter and wastewater can cause reactions between floating microorganisms and the wastewater, potentially leading to re-contamination. Therefore, frequent filter replacement is necessary. Currently, most wastewater treatment equipment requires regular filter replacement by designated personnel based on operating conditions, necessitating equipment shutdown. When wastewater contains a large amount of flocculent matter, filter replacement becomes very frequent, reducing the continuity of filtration and consequently lowering treatment efficiency.

[0003] Currently, Chinese invention patent CN110759502A, published on February 7, 2020, discloses a treatment device for industrial wastewater with a flocculent material treatment component. The device includes a sedimentation mechanism, a drive mechanism, a filtration mechanism, a drainage mechanism, and a decontamination mechanism. The sedimentation mechanism comprises a sedimentation tank and an effluent hopper. The drive mechanism is installed at the top of the sedimentation tank. The decontamination mechanism is installed inside the sedimentation tank. The drive mechanism is installed at the top of the sedimentation tank and is connected to the decontamination mechanism via a transmission connection. The drainage mechanism is installed on the side wall of the sedimentation tank and located at the bottom of the filtration mechanism. The filtration mechanism includes a fixed frame, a movable trough, filter plates, baffles, a support frame, connecting columns, fixing nuts, and a rotating shaft. The fixed frame is fixedly connected to the opposite side walls of the sedimentation tank. The rotating shaft is installed between the fixed frames, and the surface of the rotating shaft is rotatably connected to the connecting columns. The connecting columns and the rotating shaft are fixedly connected by fixing nuts. Support frames are welded to the surface of the connecting columns at equal intervals. Filter plates are slidably connected between the longitudinal support frames. The surface of the connecting columns between adjacent filter plates is welded with baffles parallel to the rotating shaft to prevent wastewater splashing. The side wall of the sedimentation mechanism has a movable trough to provide rotation space for the support frames and filter plates. The filter plates are located at the bottom of the effluent hopper.

[0004] When the wastewater in the sedimentation tank is discharged from the effluent hopper, the wastewater flows directly onto the surface of the filter plate. The flocculent matter in the wastewater is filtered by the filter plate, and the wastewater after the flocculent matter is filtered out flows out from the bottom of the filter plate. When the filter plate needs to be replaced, the support frame can be rotated clockwise to replace it with the next filter plate.

[0005] Regarding the aforementioned solutions, the inventors believe that during wastewater treatment, the angle between the filter plate and the drainage hopper changes when the filter plate rotates relative to the drainage hopper. This changes the angle at which wastewater flowing from the drainage hopper towards the filter plate, potentially washing away flocculent material on the filter plate surface. Furthermore, the open structure between the filtration and drainage mechanisms allows flocculent material washed away from the filter plate to fall into the drainage mechanism, potentially causing secondary pollution of the water. To reduce the probability of secondary pollution, operators must pause wastewater discharge from the sedimentation tank when rotating the filter plate, and then resume drainage after the filter plate has rotated to its correct position. This operation reduces the continuity of filter plate operation, thereby decreasing wastewater treatment efficiency. Summary of the Invention

[0006] In order to improve the wastewater treatment efficiency without reducing the quality of wastewater treatment, the present invention provides a wastewater treatment device that can treat flocculent matter.

[0007] The present invention provides a wastewater treatment device capable of treating flocculent materials, which adopts the following technical solution:

[0008] A wastewater treatment device capable of treating flocculent matter includes a water storage tank, a flocculent matter filtration mechanism, a drainage mechanism, and a cleaning mechanism for cleaning the filter screen. The water storage tank is provided with a first inlet and a first outlet. The flocculent matter filtration mechanism includes a first support base, a filter screen, and a first driving component for moving the filter screen. The first support base is located on the ground, the fixed end of the first driving component is mounted on the first support base, and the movable end of the first driving component is connected to the filter screen, which is located below the first outlet. The drainage mechanism is provided with a second inlet and a second outlet, the second inlet being located below the filter screen, and the second outlet being connected to a designated conveying pipeline. The cleaning mechanism includes a second support base and a spray assembly. The second support base is located on the ground, and the spray assembly is mounted on the second support base. The spray assembly is located at the end of the filter screen furthest from the drainage mechanism, and the spraying direction of the spray assembly is opposite to the direction in which the wastewater enters the filter screen.

[0009] By adopting the above technical solution, when the wastewater in the storage tank needs to be filtered for flocculent matter, the wastewater flows onto the filter screen through the first outlet. The filter screen retains the flocculent matter on its surface. The wastewater without flocculent matter flows into the drainage mechanism through the second inlet and then is discharged into the designated conveying pipeline through the second outlet, thus completing the filtration of flocculent matter in the wastewater. When there is too much flocculent matter on the filter screen, clogging it, the first drive component is activated. The first drive component moves the filter screen, causing the end of the filter screen with accumulated flocculent matter to move to the position of the spray component. The spray head is then turned on, spraying water onto the filter screen to clean it. At the same time, the end of the filter screen without accumulated flocculent matter moves below the first drain outlet to continue filtering the wastewater. By configuring the first drive component, the end of the filter screen with accumulated flocculent material moves away from the first inlet. The spray head only cleans the flocculent material from the filter screen when this end reaches the spray assembly. This reduces the probability of flocculent material entering the drainage mechanism during filter screen movement and cleaning, ensuring the filtration quality of wastewater in the drainage mechanism. Simultaneously, during cleaning, the filter screen without accumulated flocculent material remains below the first drain outlet, filtering the wastewater flowing from the storage tank, maintaining continuous filtration and thus improving wastewater treatment efficiency. Furthermore, the cleaning mechanism allows for online cleaning of the filter screen without removal from the equipment, significantly reducing operator workload and improving cleaning efficiency.

[0010] Optionally, the filter screen is a flexible annular filter screen. The first driving assembly includes a first rotating shaft, a second rotating shaft, and a first driving member. The first rotating shaft and the second rotating shaft are symmetrically arranged at both ends of the length direction of the first support base. Both the first rotating shaft and the second rotating shaft are rotatably connected to the first support base. One end of the filter screen is wrapped around the first rotating shaft, and the other end of the filter screen is wrapped around the second rotating shaft. The filter screen is in a tensioned state. The fixed end of the first driving member is connected to the first support base, and the output end is connected to one end of the first rotating shaft.

[0011] By adopting the above technical solution, when wastewater in the storage tank flows onto the filter screen, the first driving component is simultaneously activated. The first driving component drives the first rotating shaft to rotate, which in turn drives the filter screen to rotate. The rotation of the filter screen then drives the second rotating shaft to rotate, thereby achieving a circular movement of the filter screen between the first and second rotating shafts. This arrangement ensures that the filter screen is always positioned below the first outlet and moves in a circular motion, indirectly increasing the filtration area of ​​the filter screen and reducing the probability of filter screen clogging due to the accumulation of flocculent material per unit time, thus indirectly improving the filtration efficiency of the filter screen. In addition, during the circular movement of the filter screen, the cleaning mechanism can achieve real-time cleaning of flocculent material on the filter screen, reducing the accumulation of flocculent material and facilitating the cleaning of the filter screen flocculent material.

[0012] Optionally, the flocculent filtration mechanism further includes a support assembly for supporting the filter screen. The support assembly includes an adjusting plate and a roller. The roller is rotatably connected to the adjusting plate and is positioned below the first and second rotating shafts. The roller's axis is parallel to the axis of the first rotating shaft, and its outer circle abuts against the loose edge of the filter screen. The adjusting plate is movably connected to the first support base in the vertical direction.

[0013] By adopting the above technical solution, because the filter screen is a flexible structure, it is prone to deformation after the filter screen moves in a circular motion for a period of time. This causes the filter screen circumference to increase and the bottom edge to droop, making it prone to slippage during the circular movement and affecting the filtration effect. By setting up a support component, when the bottom edge of the filter screen droops, the vertical position of the movable mounting base on the first support base can be adjusted to adjust the height of the roller, thereby adjusting the tension of the filter screen, reducing the probability of filter screen slippage, and ensuring the normal operation of the filter screen.

[0014] Optionally, the flocculent filtration mechanism further includes a sealing component for sealing during the movement of the filter screen; the sealing component includes a baffle and a sealing brush, the baffle is disposed below the first outlet and above the filter screen, the opposite sides of the baffle are respectively disposed on both sides of the filter screen in the width direction and are both connected to the first support base, and the other side of the baffle is disposed directly above the filter screen; one end of the sealing brush is connected to the side of the baffle, and the other end abuts against the surface of the filter screen.

[0015] By adopting the above technical solution, when the filter screen moves in a ring, the wastewater flowing from the storage tank is prone to splashing as it enters the filter screen, which may cause unfiltered wastewater to fall into the drainage mechanism, thereby reducing the filtration quality of the wastewater in the drainage mechanism. According to the above operation, by setting baffles and sealing brushes above the filter screen, the probability of wastewater splashing into the drainage mechanism during the process of wastewater falling onto the filter screen is reduced, ensuring the filtration effect of the wastewater in the drainage mechanism. At the same time, the sealing brush bristles can also cause the flocculent material embedded on the edge of the filter screen to adhere to the filter screen surface while sealing, facilitating the subsequent cleaning of the flocculent material on the filter screen by the cleaning mechanism.

[0016] Optionally, the spray assembly includes a spray head and a water supply tank for supplying water to the spray head. The water supply tank is installed on the ground and has a third water inlet and a third water outlet. The spray head is connected to the third water outlet. The cleaning mechanism also includes a second drive assembly for driving the spray head to move. The fixed end of the second drive assembly is connected to a second support base, and the moving end of the second drive assembly is connected to the spray head. The spray head has multiple spray holes along a direction perpendicular to the movement direction of the second drive assembly.

[0017] By adopting the above technical solution, when the cleaning mechanism cleans the filter screen, it operates the second drive component. The second drive component moves the spray head, and water from the water supply tank enters the spray head. All the spray holes on the spray head spray water onto the areas of the filter screen that need cleaning. This setup increases the cleaning range of the filter screen and improves the cleaning efficiency.

[0018] Optionally, the cleaning mechanism further includes a brush assembly, which includes a brush roller and two connecting brackets. The brush roller is disposed on the side of the filter screen away from the spray head, and the outer circumference of the brush roller abuts against the surface of the filter screen. The axis of the brush roller is parallel to the length direction of the spray head. The two connecting brackets are respectively disposed at both ends of the spray head, one connecting bracket being rotatably connected to one end of the brush roller, and the other connecting bracket being rotatably connected to the other end of the brush roller.

[0019] By adopting the above technical solution, during the filter cleaning process, as the spray head moves, it drives the brush roller to move as well. The brush roller generates friction with the filter screen surface, and under this friction, the brush roller rotates relative to the filter screen surface. This causes the flocculent material on the filter screen surface to adhere to the brush roller, allowing the flocculent material to be quickly separated from the filter screen. This operation accelerates the cleaning speed of flocculent material on the filter screen and also reduces the amount of flocculent material mixed in the water after cleaning.

[0020] Optionally, the cleaning mechanism also includes a water circulation component for circulating water in the water supply tank. The water circulation component includes a spray water collection tank, a first water pump, and a second water pump. The spray water collection tank is located on the ground and has a fourth water inlet and a fourth water outlet. The fourth water inlet is located below the spray position of the spray head. The first water pump is located on a water storage tank. The inlet of the first water pump is connected to the fourth water outlet, and the outlet of the first water pump is connected to the first water inlet. The second water pump is located on the water supply tank. The inlet of the second water pump is connected to the second water outlet, and the outlet of the second water pump is connected to the third water inlet.

[0021] By adopting the above technical solution, before cleaning the filter screen, the second water pump is run to draw water from the drainage mechanism into the water supply tank through the second outlet. During filter screen cleaning, the water supply tank supplies water to the spray heads through the third outlet to spray and clean the filter screen. At this time, the cleaned water enters the spray water collection tank through the fourth inlet. The first water pump is then run, and the water in the spray tank flows out from the fourth outlet and enters the storage tank through the first inlet. With this setup, because most of the flocculent material on the filter screen is separated by the brush roller during the cleaning process, the content of flocculent material mixed in the water after cleaning is reduced. Therefore, the water in the spray water collection tank enters the storage tank without increasing the wastewater treatment burden. At the same time, it can also realize the recycling of filter screen cleaning water, saving water consumption in the filter screen cleaning process and reducing the pollution caused by wastewater discharge during the cleaning process.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] 1. By incorporating a flocculant filtration mechanism, the filtration of flocculants in wastewater is achieved. Specifically, by using a first driving component to drive the filter screen in a circular motion, the filtration area of ​​the screen is indirectly increased, reducing the probability of screen clogging due to flocculant accumulation per unit time, and thus indirectly improving the filtration efficiency. The sealing component further reduces the probability of unfiltered wastewater entering the drainage system during filtration, ensuring the quality of wastewater treatment in the drainage system. This design improves both wastewater filtration efficiency and wastewater treatment quality.

[0024] 2. By incorporating a cleaning mechanism, the filter screen is automatically cleaned during operation, eliminating the need for disassembly and replacement, and reducing the labor intensity for staff. The brush assembly allows lint on the filter screen surface to be adsorbed onto the brush rollers, enabling rapid separation of the lint from the screen. Furthermore, the water circulation component allows for the recycling of water used for filter screen cleaning, conserving water consumption and reducing wastewater pollution during the cleaning process.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be described in further detail below.

[0035] This invention discloses a wastewater treatment device capable of treating flocculent materials, as shown in the attached drawing. Figure 1A wastewater treatment device capable of treating flocculent matter includes: a water storage tank 100, a drainage mechanism 200, a flocculent matter filtration mechanism 300, and a cleaning mechanism 400. The water storage tank 100 is located on the ground, the drainage mechanism 200 is located on the side wall of the water storage tank 100, the flocculent matter filtration mechanism 300 is located on the ground and directly above the drainage mechanism 200, and the cleaning mechanism 400 is located at the end of the flocculent matter filtration mechanism 300 away from the drainage mechanism 200. When wastewater in the water storage tank 100 needs to be filtered, the wastewater flows out of the water storage tank 100, is filtered by the flocculent matter filtration mechanism 300, and then flows into the drainage mechanism 200. The filtered wastewater is then discharged from the drainage mechanism 200 into a designated pipe. When a large amount of flocculent matter accumulates on the filtration mechanism, affecting the wastewater treatment efficiency, the cleaning mechanism 400 is activated to automatically clean the accumulated flocculent matter on the flocculent matter filtration mechanism 300, thereby restoring the filtration efficiency of the flocculent matter filtration mechanism 300.

[0036] Reference Figure 1 and Figure 2 The water storage tank 100 has a support frame welded to its bottom, which is placed on the ground. A first water inlet 101 is welded to the upper end of the water storage tank 100, and a first water outlet 102 is welded to the outer wall of the water storage tank 100, extending a certain distance beyond the outer wall of the water storage tank 100. The drainage mechanism 200 includes a drainage tank 201, which is placed on the ground. The side wall of the drainage tank 201 abuts against the side wall of the water storage tank 100, and the drainage tank 201 and the first water outlet 102 are located on the same side wall of the water storage tank 100. A third water inlet 4221 is provided at the end of the drainage tank 201 opposite to the first water outlet 102.

[0037] Reference Figure 1 , Figure 3 and Figure 6The flocculent filtration mechanism 300 includes a first support base 310, a filter screen 320, and a first drive assembly 330. The first support base 310 is bolted to the ground. The first drive assembly 330 includes a first drive element 333, a first rotating shaft 331, and a second rotating shaft 332. In this invention, the first drive element 333 is a drive motor. The first rotating shaft 331 and the second rotating shaft 332 are rotatably connected to the upper surface of the first support base 310 via bearing seats. The first rotating shaft 331 and the second rotating shaft 332 are symmetrically arranged at both ends of the first support base 310 along its length. The second rotating shaft 332 is closer to the water storage tank 100, and the first rotating shaft 331 is farther away from the water storage tank 100. The filter screen 320 is a flexible annular filter screen 320. One end of the filter screen 320 is wrapped around the first rotating shaft 331, and the other end of the filter screen 320 is wrapped around the second rotating shaft 332. The filter screen 320 is in a taut state. The first drive unit 333 is bolted to the first support base 310, and the output shaft of the first drive unit 333 is coaxially connected to the end of the first rotary shaft 331.

[0038] Reference Figure 1 , Figure 3 and Figure 6 The flocculent filtration mechanism 300 further includes a support assembly 340, which includes a roller 341, an adjusting plate 342, two adjusting bolts 343, and four mounting nuts 344. One end of each of the two adjusting bolts is welded to both sides of the width direction of the first support base 310, and the adjusting bolts 343 are vertically upward. Both ends of the adjusting plate 342 are provided with first through holes, and the two adjusting bolts 343 are respectively inserted into the first through holes. Each adjusting bolt 343 is threadedly connected to two mounting nuts 344, and the two mounting nuts 344 respectively abut against the upper and lower end faces of the adjusting plate 342. Both ends of the roller 341 are rotatably connected to the adjusting plate 342 through bearing seats.

[0039] Reference Figure 1 , Figure 3 and Figure 6 The flocculent filtration mechanism 300 further includes a sealing assembly 350; the sealing assembly 350 includes a baffle 351 and a sealing brush 352. The baffle 351 has a U-shaped structure and is located above the filter screen 320. The opposite sides of the baffle 351 are respectively arranged on both sides of the filter screen 320 in the width direction and are connected to the two sides of the first support base 310 in the width direction. The U-shaped opening of the baffle 351 is away from the water storage tank 100, and the wastewater flowing out from the first outlet 102 enters the filter screen 320 at the inside of the U-shaped opening of the baffle 351. One end of the sealing brush 352 is attached to the end of the baffle 351 near the filter screen 320, and the other end abuts against the surface of the filter screen 320.

[0040] When the wastewater in the storage tank 100 needs to be filtered, the first drive component 333 is activated. The first drive component 333 drives the first rotating shaft 331 to rotate. The rotation of the first rotating shaft 331 drives the filter screen 320 to rotate. The filter screen 320 drives the second rotating shaft 332 and the idler roller 341 to rotate. As a result, the filter screen 320 moves in a ring between the first rotating shaft 331 and the second rotating shaft 332. When the filter screen 320 becomes longer and its bottom edge droops during the ring movement, the position of the mounting nut 344 on the adjusting bolt 343 can be adjusted to correct the vertical position of the adjusting plate 342, thereby adjusting the vertical position of the idler roller 341. This allows the bottom edge of the filter screen 320 to return to a taut state under the support of the idler roller 341. This setting can reduce the probability of the filter screen 320 slipping during the ring movement, so as to maintain the filtration effect of the filter screen 320. Meanwhile, wastewater flows out through the first outlet 102 and falls onto the filter screen 320 from the U-shaped opening on the baffle 351. Because a sealing brush 352 is installed between the baffle 351 and the filter screen 320, the sealing brush 352 reduces the probability of unfiltered wastewater entering the drainage tank 201. Subsequently, the wastewater continues to fall through the filter screen 320. During this fall, flocculent matter in the wastewater remains on the surface of the filter screen 320, while wastewater without flocculent matter flows into the drainage tank 201 through the second inlet 202. Because the filter screen 320 moves in a circular motion throughout the filtration process, this design indirectly increases the filtration area of ​​the filter screen 320, reduces the probability of clogging caused by flocculent matter accumulation per unit time, indirectly improves the filtration efficiency of the filter screen 320, and thus improves the wastewater treatment efficiency.

[0041] See attached document Figure 4 -Appendix Figure 5The cleaning mechanism 400 includes a second support base 410, a second drive assembly 430, and a spray assembly 420. The second support base 410 is arranged between the first rotating shaft 331 and the second rotating shaft 332, and is close to one end of the first rotating shaft 331. The second support base 410 is bolted to the ground. The second drive assembly 430 includes a second drive member 431, a gear 432, a rack 433, two linear guide rails 434, and two sliders 435. One linear guide rail 434 corresponds to one slider 435. The two linear guide rails 434 are symmetrically arranged on both sides of the second support base 410, and both linear guide rails 434 are bolted to the two sides of the second support base 410. The spray assembly 420 includes a spray head 421 and a water supply tank 422. The water supply tank 422 is bolted to the ground. A third water outlet 4222 is provided on the water supply tank 422 and is connected to the spray head 421. The two ends of the spray head 421 are bolted to two sliders 435 respectively. The two sliders 435 slide on two linear guide rails 434 respectively, and the movement direction of the sliders 435 is parallel to the movement direction of the filter screen 320. The spray head 421 is located between the loose side and the tight side of the filter screen 320 and is closer to the loose side. The spray head 421 has multiple water outlets along its length. The water outlets are perpendicular to the surface of the filter screen 320 and face downwards. The rack 433 is bolted along the length of the guide rail to any side of the second support 410 where the linear guide rail 434 is installed. The spray head 421 has a gear 432 mounting hole vertically opened at one end near the rack 433. One end of the gear 432 passes through the gear 432 mounting hole and is coaxially keyed to the second drive member 431. The other end of the gear 432 meshes with the rack 433 for transmission. The second drive member 431 in this invention is a drive motor. The output shaft of the second drive member 431 passes coaxially through the motor mounting hole. The fixed end of the second drive member 431 is fixedly connected to the spray head 421 by bolts.

[0042] Reference Figure 2 , Figure 4 , Figure 5 and Figure 7 The cleaning mechanism 400 also includes a brush assembly 440, which includes a brush roller 441 and two connecting brackets 442. The two connecting brackets 442 are symmetrically arranged at both ends of the brush roller 441. One end of the connecting bracket 442 is bolted to one end of the spray head 421, and the other end is rotatably connected to both ends of the brush roller 441 through bearings. The brush roller 441 is located on the side of the filter screen 320 away from the spray head 421, and the axis of the brush roller 441 is parallel to the length direction of the spray head 421. The outer circle of the brush roller 441 abuts against the surface of the filter screen 320.

[0043] Reference Figure 7 and Figure 8The cleaning mechanism 400 also includes a water circulation assembly 450, which includes a spray water collection tank 451, a first water pump 452, and a second water pump 453. The spray water collection tank 451 is bolted to the ground, and has a fourth water inlet 4511 and a fourth water outlet 4512. The fourth water inlet 4511 is located directly below the spray position of the spray head 421. The first water pump 452 is bolted to the ground. On the upper surface of the water storage tank 100, the inlet of the first water pump 452 is connected to the fourth outlet 4512 via a water pipe, the outlet of the first water pump 452 is connected to the first inlet 101 via a water pipe, the second water pump 453 is bolted to the upper surface of the water supply tank 422, the inlet of the second water pump 453 is connected to the second outlet 203 via a water pipe, and the outlet of the second water pump 453 is connected to the third inlet 4221 via a water pipe.

[0044] As the filter screen 320 moves in a circular motion, the fibrous material on the filter screen 320 is moved to one end of the first rotating shaft 331. At this time, the water supply tank 422 supplies water to the spray head 421 through the third water outlet 4222. The spray head 421 sprays water onto the filter screen 320 from the water outlet. Simultaneously, the second drive component 431 is activated, driving the gear 432 to rotate. Through the meshing transmission of the gear 432 and rack 433, the spray head 421 reciprocates along the moving direction of the filter screen 320. By moving the spray head 421, the cleaning range of the filter screen 320 is increased, improving the cleaning efficiency of the filter screen 320. At the same time, the spray head 421 drives the brush roller 441 to move. The brush roller 441 rotates on the surface of the filter screen 320, causing the fibrous material on the filter screen 320 to be adsorbed onto the brush roller 441, completing the cleaning process. The cleaning of flocculent matter on the filter screen 320 is achieved by using a brush roller 441, which speeds up the cleaning process and reduces the amount of flocculent matter mixed in the water after cleaning. Simultaneously, water flowing from the spray nozzle 4211 cleans the filter screen 320 and then flows into the spray water collection tank 451 through the fourth inlet 4511. When there is a large amount of wastewater in the spray water collection tank 451, the first water pump 452 is activated, causing the wastewater in the spray tank to flow into the first inlet 101 through the fourth outlet 4512, and then back into the water storage tank 100. When the water volume in the water supply tank 422 decreases, the second water pump 453 is activated, causing water from the drainage tank 201 to enter the third inlet 4221 through the second outlet 203, and then flow into the water supply tank 422. This operation allows for the recycling of water used for cleaning the 320 filter screen, saving water consumption during the cleaning process and reducing environmental pollution caused by wastewater discharge.

[0045] The implementation principle of a wastewater treatment device capable of treating flocculent materials according to an embodiment of the present invention is as follows:

[0046] When the wastewater in the storage tank 100 needs to be filtered, the first drive component 333 is activated. The first drive component 333 drives the first rotating shaft 331 to rotate. The rotation of the first rotating shaft 331 drives the filter screen 320 to rotate. The filter screen 320 drives the second rotating shaft 332 and the idler roller 341 to rotate, thereby causing the filter screen 320 to move in a ring between the first rotating shaft 331 and the second rotating shaft 332. When the filter screen 320 becomes longer in the ring movement and the bottom edge droops, the position of the mounting nut 344 on the adjusting bolt 343 can be adjusted to correct the vertical position of the adjusting plate 342, thereby adjusting the vertical position of the idler roller 341. This allows the bottom edge of the filter screen 320 to return to a taut state under the support of the idler roller 341. This setting can reduce the probability of the filter screen 320 slipping during the ring movement, so as to maintain the filtration effect of the filter screen 320. Meanwhile, wastewater flows out through the first outlet 102 and falls onto the filter screen 320 from the U-shaped opening on the baffle 351. Because a sealing brush 352 is installed between the baffle 351 and the filter screen 320, the sealing brush 352 reduces the probability of unfiltered wastewater entering the drainage tank 201. Subsequently, the wastewater continues to fall through the filter screen 320. During this fall, flocculent matter in the wastewater remains on the surface of the filter screen 320, while wastewater without flocculent matter flows into the drainage tank 201 through the second inlet 202. Because the filter screen 320 moves in a circular motion throughout the filtration process, this design indirectly increases the filtration area of ​​the filter screen 320, reduces the probability of clogging caused by flocculent matter accumulation per unit time, indirectly improves the filtration efficiency of the filter screen 320, and thus improves the wastewater treatment efficiency.

[0047] Simultaneously, as the filter screen 320 moves in a circular motion, the fibrous material on the filter screen 320 is moved to one end of the first rotating shaft 331. At this time, the water supply tank 422 supplies water to the spray head 421 through the third water outlet 4222. The spray head 421 sprays water onto the filter screen 320 from the water outlet. At the same time, the second driving component 431 is activated, driving the gear 432 to rotate. Through the meshing transmission of the gear 432 and rack 433, the spray head 421 reciprocates along the moving direction of the filter screen 320. By moving the spray head 421, the cleaning range of the filter screen 320 is increased, improving the cleaning efficiency of the filter screen 320. At the same time, the spray head 421 drives the brush roller 441 to move. The brush roller 441 rotates on the surface of the filter screen 320, causing the fibrous material on the filter screen 320 to be adsorbed onto the brush roller 441, thus completing the process. The cleaning of flocculent matter on the paired filter screens 320; the setting of the brush roller 441 can accelerate the cleaning speed of flocculent matter on the filter screens 320, and also reduce the content of flocculent matter mixed in the water after cleaning the filter screens 320; at the same time, the water flowing out of the spray hole 4211 after cleaning the filter screens 320 flows into the spray water collection tank 451 through the fourth water inlet 4511. When there is a lot of wastewater in the spray water collection tank 451, the first water pump 452 is run, so that the wastewater in the spray tank flows into the first water inlet 101 through the fourth water outlet 4512, and then flows back into the water storage tank 100; when the water volume in the water supply tank 422 decreases, the second water pump 453 is run, so that the water in the drainage tank 201 enters the third water inlet 4221 through the second water outlet 203, and then flows into the water supply tank 422. This operation allows for the recycling of water used for cleaning the 320 filter screen, saving water consumption during the cleaning process and reducing environmental pollution caused by wastewater discharge.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
