Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for the production of nonwoven compressed towels. Background Technology

[0002] Non-woven fabrics are mainly made of polyester fibers and polyester fibers, using non-woven processes such as needle punching, spunbonding, and thermal bonding. They have many excellent properties such as good air permeability, moisture resistance, flame retardancy, light weight, non-toxicity, odorlessness, biodegradability, and low cost. Based on these performance characteristics, non-woven fabrics are often processed into compressed towel products. However, in the actual production and processing of non-woven compressed towels, a large amount of wastewater is generated. In order to meet environmental protection emission requirements, a special wastewater treatment device is required to purify the wastewater.

[0003] While existing wastewater treatment devices can filter flocculent matter and debris in wastewater through internal grids, these flocculent matter and debris tend to adhere and accumulate on the inner wall of the tank during long-term use, and are difficult to remove on their own. This accumulation not only reduces the filtration efficiency of the wastewater treatment device but also easily causes blockage of the water flow channels and increases the operating resistance of the equipment. It also significantly increases the difficulty and cost of subsequent cleaning and maintenance. Therefore, there is an urgent need for a wastewater treatment device for the production of non-woven compressed towels. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a wastewater treatment device for the production of non-woven compressed towels.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A wastewater treatment device for non-woven compressed towel production includes a wastewater treatment tank. The top of the wastewater treatment tank is provided with a top cover. A wastewater pipe for conveying wastewater into the wastewater treatment tank and a dosing pipe for adding wastewater treatment agent into the wastewater treatment tank are symmetrically arranged on the top of the top cover. The inside of the wastewater treatment tank is also provided with several filter frames for filtering wastewater. A scraping mechanism for driving the filter frames to rise and fall is also provided between the wastewater treatment tank and the filter frames. The scraping mechanism can also be used to clean debris and flocculent sludge adhering to the inner wall of the sewage treatment tank, preventing sludge from sticking to the inner wall of the sewage treatment tank. The scraping mechanism includes a transmission rod rotatably mounted at the bottom of the top cover. A servo motor that drives the transmission rod to rotate is fixed at the end of the transmission rod away from the top cover. A positioning plate is also provided on the lower half of the transmission rod. A cleaning plate for scraping the inner wall of the sewage treatment tank is provided above the positioning plate. A sealing plate for temporarily storing filtered sewage is also provided on the lower half of the transmission rod. A collar is also provided below the positioning plate. The collar is sleeved on the outside of the transmission rod. The outer wall of the transmission rod is provided with a threaded groove. The inside of the collar is also provided with a threaded block that matches the threaded groove.

[0006] As a preferred embodiment of the present invention, a fixing ring is also fixed to the outside of the positioning plate, and an installation groove adapted to the filter frame is formed between the fixing ring and the positioning plate. A pressure plate for applying pressure to the filter frame is also provided above the positioning plate. The outer wall of the collar is also fixed with several locking rods. The end of the locking rod away from the collar passes through the filter frame, and the top of the locking rod extends through the filter frame into the interior of the pressure plate. The pressure plate has a limiting hole at its bottom that matches the locking rod. The pressure plate is sleeved on the outside of the transmission rod, and the top of the locking rod is inserted into the limiting hole. The locking rod is L-shaped, and the bottom of the filter frame contacts the bend of the locking rod. The bend of the locking rod can limit the filter frame and prevent it from falling out of the mounting groove. The fixing ring and the pressure plate are made of solid and uniform material, and the material density of the pressure plate is greater than that of the sewage. The buoyancy of the fixing ring and the pressure plate in the sewage is less than their weight in the water, so they can sink naturally in the water. The collar is set below the positioning plate. The output shaft of the servo motor drives the transmission rod to rotate. The threaded groove on the outside of the transmission rod cooperates with the threaded block of the collar, so that the collar moves vertically up and down along the outer wall of the transmission rod. The collar drives the positioning plate and the locking rod to move upward, the positioning plate drives the fixing ring to move upward, and the locking rod drives the guide ring to move upward synchronously with the fixing ring and the positioning plate, thus filtering the sewage inside the sewage treatment tank through the filter frame.

[0007] As a preferred technical solution of the present invention, a pressure cover is rotatably connected to the top of the transmission rod, a retaining ring is fixed to the bottom of the pressure cover, a limiting ring is provided at the bottom of the retaining ring, a slot adapted to the retaining ring is opened on the top of the pressure plate, and an annular groove adapted to the limiting ring is provided at the bottom of the slot. The top of the positioning plate is also fixed with a flow guide ring, and the top edge of the flow guide ring is recessed downward to form a flow guide slope. The pressure cover has an arc surface at its top, which allows wastewater on the upper surface of the pressure cover to be guided into the interior of the filter frame. The retaining ring and the limiting ring cooperate to rotate the pressure cover and mount it above the pressure plate. The guide ring's guide slope guides the wastewater that falls after the inner wall of the wastewater treatment tank is scraped off to the interior of the filter frame for filtration.

[0008] As a preferred embodiment of the present invention, a bellows is further sleeved on the outside of the transmission rod, the top of the bellows is fixed to the bottom of the top cover, and the bottom of the bellows is fixed to the top of the pressure cover.

[0009] When the positioning plate moves the pressure cover upward, the pressure cover causes the bellows to contract. The bellows is sleeved on the outside of the transmission rod, protecting the transmission rod immersed in sewage and preventing debris in the sewage in the sewage treatment tank from entering the threaded groove, thus preventing the bellows from being unable to rotate and rise normally.

[0010] As a preferred embodiment of the present invention, the cleaning plate is movably connected above the positioning plate, and the side of the cleaning plate near the inner wall of the sewage treatment tank is provided with a cleaning arc surface adapted to the inner wall of the sewage treatment tank. The cleaning plate is designed in an arc shape, and a dirt removal slope is provided on the side of the cleaning plate away from the sewage treatment tank. The impurity removal slope effectively removes debris adhering to the inner wall of the sewage treatment tank, achieving internal cleaning. When the positioning plate rotates and moves upward, it drives the filter plate to rotate and move upward synchronously. During the rotation, the cleaning plate scrapes the inner wall of the sewage treatment tank, while the filter plate moves upward and rotates accordingly, working in conjunction with the cleaning plate to simultaneously scrape away debris from the inner wall of the sewage treatment tank. This achieves multi-layered and all-round scraping and cleaning of the inner wall of the sewage treatment tank, thoroughly removing flocculent matter and dirt adhering to the inner wall, preventing debris from accumulating and affecting the sewage treatment effect, and significantly improving the cleanliness of the sewage treatment tank and the stability of equipment operation.

[0011] As a preferred embodiment of the present invention, a positioning rod is fixed to the top of the positioning plate, a limiting plate is fixed to the side of the cleaning plate near the positioning rod, a filter plate is inserted between the positioning rod and the limiting plate, and a filter screen is provided in the middle of the filter plate. Both ends of the filter plate are fixed with pins, and the positioning rod and the limiting plate are provided with insertion holes that are compatible with the pins on the opposite side. The filter plate is inserted between the positioning rod and the limiting plate via the pins. The filter plate's own weight is greater than its buoyancy in the sewage. Pushing the filter plate downward causes it to drive the two pins to be inserted into the holes, thus installing the filter plate on the side of the positioning rod away from the transmission rod. Pushing the cleaning plate downward causes it to drive the limiting plate to move downward, thus installing the limiting plate on the outside of the pins on the side of the filter plate away from the positioning rod.

[0012] As a preferred technical solution of the present invention, a waterproof sleeve is also fixed at the bottom of the top cover, and two fixing plates are fixed on the outer wall of the waterproof sleeve. A secondary barrier block and a main barrier block adapted to the sewage pipe and the dosing pipe are also provided at the ends of the two fixing plates away from the waterproof sleeve. Both the secondary barrier block and the main barrier block are fixed with lifting rods at their bottoms. The bottom of the lifting rods is fixed with limit plates, and the lifting rods are inserted into the end of the fixing plate away from the waterproof sleeve. The secondary barrier block is located below the sewage pipe, and the primary barrier block is located below the dosing pipe. When the positioning plate moves upward, it drives the filter plate to move upward. The top of the filter plate contacts the bottom of the two limiting plates. The filter plate pushes the two lifting rods upward through the limiting plates. The two lifting rods drive the secondary barrier block and the primary barrier block to move upward respectively, so that the secondary barrier block enters the interior of the sewage pipe and the primary barrier block enters the interior of the dosing pipe, thereby achieving the sealing of the sewage pipe and the dosing pipe.

[0013] As a preferred embodiment of the present invention, a water generator is also fixed at the bottom of the sealing disc, and the water inlet pipe of the water generator extends to the top of the sealing disc. The power output terminal of the hydroelectric generator is connected to the servo motor via a wire, and the water outlet terminal of the hydroelectric generator is equipped with a water outlet pipe that extends to the outside of the sewage treatment tank. The sealing disc has a through-hole on its surface, which corresponds to the inlet port of the hydroelectric generator. This allows water filtered by the sealing disc to flow directly into the inlet pipe of the hydroelectric generator through the through-hole. Wastewater inside the wastewater treatment tank is filtered through a filter frame and filter plate and then flows to the top of the sealing disc. The filtered water above the sealing disc flows into the inlet pipe of the hydroelectric generator through the through-hole. The potential energy generated by the falling filtered water drives the hydroelectric generator to work. The electrical energy generated by the hydroelectric generator is transmitted to the servo motor through wires to provide power to the servo motor.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are: This invention utilizes the coordinated structure of a filter frame, scraping mechanism, transmission rod, hydraulic generator, servo motor, pressure cover, pressure plate, locking rod, collar, filter plate, cleaning plate, and positioning rod to drive the cleaning plate to rotate synchronously and move upward, ensuring that the cleaning plate fits tightly against the inner wall of the wastewater treatment tank. With the help of the cleaning plate's impurity-removing inclined surface and its rotating upward trajectory, it efficiently scrapes away fibrous flocs and impurities adhering to the tank wall in the wastewater from non-woven fabric production. This avoids problems such as water flow obstruction and reduced filtration efficiency caused by impurity accumulation on the inner wall of the wastewater treatment tank, ensuring a smooth wastewater treatment process and guaranteeing long-term continuous and reliable operation of the device. This invention utilizes a structure consisting of a transmission rod, a hydraulic generator, a servo motor, a fixed ring, a positioning plate, a filter frame, a locking rod, and a collar to dynamically adapt the filter frame to the wastewater level, enabling continuous and uninterrupted filtration of wastewater from non-woven fabric production. This effectively prevents the accumulation and blockage of fibrous material and production debris in the filtration area, significantly reducing the probability of clogging of filter components and the filtration load, and continuously ensuring the filtration efficiency and purification quality of wastewater treatment. This invention utilizes a combination of a transmission rod, a bellows, a fixing ring, a positioning plate, a pressure cover, and a pressure plate to drive the pressure cover to stretch and contract the bellows. This provides a fully enclosed protection for the transmission rod immersed in sewage, preventing fibers and debris from the non-woven fabric sewage from entering the transmission channel and causing jamming. This ensures stable operation of the transmission and lifting mechanism, reduces the frequency of equipment downtime, lowers the maintenance difficulty of the sewage treatment device, extends the service life of core components, and ensures continuous and stable sewage treatment operations. This invention achieves rapid assembly and disassembly of the cleaning plate and filter plate through the cooperation of structures such as positioning plate, filter plate, cleaning plate, positioning rod and limiting plate. The replacement and cleaning of parts can be completed without complicated tools. It effectively removes sticky flocculent matter adhering to the filter and scraping parts of non-woven wastewater, greatly improves maintenance efficiency, reduces operation and maintenance costs, and always keeps the filtration and scraping functions in the best working state, so as to stably ensure the purification effect and treatment efficiency of wastewater treatment. This invention utilizes a combination of structures including a top cover, waterproof sleeve, main barrier block, fixing plate, lifting rod, limiting plate, and secondary barrier block. When the filter plate moves to the upper half of the wastewater treatment tank, the lifting rod drives the barrier block to seal the wastewater pipe and the dosing pipe, effectively preventing backflow of non-woven wastewater and leakage and waste of wastewater treatment agent. It achieves automatic pipe sealing without manual operation, improving the automation level and operation and maintenance safety of the wastewater treatment device, avoiding the risk of pipe blockage and wastewater leakage, and ensuring safe and stable wastewater treatment operation. This invention utilizes a combination of a wastewater treatment tank, a filter frame, a sealing disc, a hydroelectric generator, and a servo motor to autonomously generate electricity by recovering and utilizing the potential energy of the falling water after filtration. This provides power to the servo motor without the need for external mains power, significantly reducing energy consumption and operating costs in non-woven wastewater treatment. This aligns with the environmental requirements of green production, energy conservation, and emission reduction. At the same time, it eliminates dependence on external power sources, preventing power outages from disrupting wastewater treatment and ensuring continuous and efficient wastewater treatment operations.

The top of the wastewater treatment tank 1 is provided with a top cover 2. The top of the top cover 2 is symmetrically provided with a wastewater pipe 3 for conveying wastewater into the wastewater treatment tank 1 and a dosing pipe 4 for adding wastewater treatment agent into the wastewater treatment tank 1. The inside of the wastewater treatment tank 1 is also provided with several filter frames 5 for filtering wastewater.

[0019] As can be seen from the above, when in use, the sewage that needs to be treated is discharged into the sewage treatment tank 1 through the sewage pipe 3, and the sewage treatment agent is added into the sewage treatment tank 1 through the dosing pipe 4. The flocculent matter and debris generated in the sewage are filtered and intercepted by several filter frames 5 set inside the sewage treatment tank 1.

[0020] refer to Figure 3 , Figure 4and Figure 5 As shown, a scraping mechanism 6 is also provided between the sewage treatment tank 1 and the filter frame 5 to drive the filter frame 5 to rise and fall. The scraping mechanism 6 can also be used to clean debris and flocculent dirt adhering to the inner wall of the sewage treatment tank 1, preventing dirt from sticking to the inner wall of the sewage treatment tank 1. The scraping mechanism 6 includes a transmission rod 601 rotatably mounted at the bottom of the top cover 2. A servo motor 607 is fixed at the end of the transmission rod 601 away from the top cover 2 to drive the transmission rod 601 to rotate. A positioning plate 604 is also provided on the lower half of the transmission rod 601. A cleaning plate 614 for scraping the inner wall of the sewage treatment tank 1 is provided above the positioning plate 604. A sealing plate 618 for temporarily storing the filtered sewage is also provided on the lower half of the transmission rod 601. The sealing disc 618 is positioned above the servo motor 607. The transmission rod 601 passes through the sealing disc 618 and is fixed to the output shaft of the servo motor 607. A collar 612 is also provided below the positioning plate 604. The collar 612 is sleeved on the outside of the transmission rod 601. The outer wall of the transmission rod 601 is provided with a threaded groove. The inside of the collar 612 is also provided with a threaded block that matches the threaded groove.

[0021] refer to Figure 3 , Figure 4 and Figure 5 As shown, a fixing ring 603 is also fixed to the outside of the positioning plate 604. An installation groove that is compatible with the filter frame 5 is formed between the fixing ring 603 and the positioning plate 604. A pressure plate 609 that applies pressure to the filter frame 5 is also provided above the positioning plate 604. Several locking rods 611 are also fixed on the outer wall of the collar 612. The end of the locking rod 611 away from the collar 612 passes through the filter frame 5, and the top of the locking rod 611 extends through the filter frame 5 into the interior of the pressure plate 609. The pressure plate 609 has a limiting hole at its bottom that matches the locking rod 611. The pressure plate 609 is sleeved on the outside of the transmission rod 601, and the top of the locking rod 611 is inserted into the limiting hole. The locking rod 611 is L-shaped. The bottom of the filter frame 5 contacts the bent part of the locking rod 611. The bent part of the locking rod 611 can limit the filter frame 5 and prevent the filter frame 5 from falling out of the mounting groove. The fixing ring 603 and the pressure plate 609 are made of solid and uniform material. The material density of the pressure plate 609 is greater than that of sewage. The buoyancy of the fixing ring 603 and the pressure plate 609 in sewage is less than that in water. Under the influence of gravity, it can sink naturally in the water. The collar 612 is set below the positioning plate 604. The output shaft of the servo motor 607 drives the transmission rod 601 to rotate. The threaded groove on the outside of the transmission rod 601 cooperates with the threaded block of the collar 612, so that the collar 612 moves vertically up and down along the outer wall of the transmission rod 601. The collar 612 drives the positioning plate 604 and the locking rod 611 to move upward. The positioning plate 604 drives the fixing ring 603 to move upward. The locking rod 611 drives the guide ring 605 to move upward synchronously with the fixing ring 603 and the positioning plate 604. The sewage inside the sewage treatment tank 1 is filtered through the filter frame 5.

[0022] refer to Figure 3 , Figure 4 and Figure 5 As shown, a pressure cover 608 is rotatably connected to the top of the transmission rod 601, a retaining ring 610 is fixed to the bottom of the pressure cover 608, a limit ring is provided at the bottom of the retaining ring 610, and a slot adapted to the retaining ring 610 is provided on the top of the pressure plate 609, and an annular groove adapted to the limit ring is provided at the bottom of the slot. The top of the positioning plate 604 is also fixed with a flow guide ring 605, and the top edge of the flow guide ring 605 is recessed downward to form a flow guide slope. The top of the pressure cover 608 is provided with an arc surface, which can guide the sewage on the upper surface of the pressure cover 608 into the interior of the filter frame 5. The retaining ring 610 and the limiting ring cooperate to rotate the pressure cover 608 and install it above the pressure plate 609. The guide slope of the guide ring 605 can guide the sewage that falls after the inner wall of the sewage treatment tank 1 is scraped into the interior of the filter frame 5 and filter it through the filter frame 5.

[0023] refer to Figure 5 , Figure 6 and Figure 7 As shown, a bellows 602 is also sleeved on the outside of the transmission rod 601. The top of the bellows 602 is fixed to the bottom of the top cover 2, and the bottom of the bellows 602 is fixed to the top of the pressure cover 608.

[0024] When the positioning plate 604 moves the pressure cover 608 upward, the pressure cover 608 causes the bellows 602 to contract. The bellows 602 is sleeved on the outside of the transmission rod 601. The bellows 602 protects the transmission rod 601 immersed in sewage, preventing debris in the sewage in the sewage treatment tank 1 from entering the spiral groove and preventing the bellows 602 from being unable to rotate and rise normally.

[0025] Sewage inside the sewage treatment tank 1 is filtered through the filter frame 5 and then transported to the inlet pipe of the hydroelectric generator 606 through the opening of the sealing plate 618. The potential energy generated by the falling filtered water drives the hydroelectric generator 606 to work. The electrical energy generated by the hydroelectric generator 606 is transmitted to the servo motor 607 through wires to provide power to the servo motor 607. The output shaft of the servo motor 607 drives the transmission rod 601 to rotate. The threaded hole on the surface of the transmission rod 601 mates with the threaded hole of the collar 612. The collar 612 moves upward along the outer wall of the transmission rod 601. The collar 612 drives the positioning plate 604 and the locking rod 611 to move upward. The positioning plate 604 drives the fixed ring 603 to move upward. The locking rod 611 drives the guide ring 605 to move upward synchronously with the fixed ring 603 and the positioning plate 604. The sewage inside the sewage treatment tank 1 is filtered through the filter frame 5. It adapts to the dynamic changes in the sewage level inside the sewage treatment tank 1 and can achieve continuous filtration without additional adjustments. It is suitable for different sewage treatment conditions and expands the applicability of the device.

[0026] refer to Figure 8 , Figure 9 and Figure 10 As shown, the cleaning plate 614 is movably connected above the positioning plate 604, and the cleaning plate 614 is provided with a cleaning arc surface that is adapted to the inner wall of the sewage treatment tank 1 on the side near the inner wall of the sewage treatment tank 1. The cleaning plate 614 is arc-shaped, and the side of the cleaning plate 614 away from the sewage treatment tank 1 is provided with a dirt removal slope. The impurity removal slope effectively removes debris adhering to the inner wall of the sewage treatment tank 1, achieving internal debris cleaning. When the positioning plate 604 rotates and moves upward, it drives the filter plate 613 to rotate and move upward synchronously. During the rotation, the cleaning plate 614 scrapes the inner wall of the sewage treatment tank 1. At the same time, the filter plate 613 moves upward and rotates, cooperating with the cleaning plate 614 to simultaneously scrape away debris from the inner wall of the sewage treatment tank 1. This achieves multi-layer and all-round scraping and cleaning of the inner wall of the sewage treatment tank 1, thoroughly removing flocculent matter and dirt adhering to the inner wall, preventing debris from accumulating and affecting the sewage treatment effect, and significantly improving the cleanliness of the sewage treatment tank 1 and the stability of equipment operation.

[0027] refer to Figure 8 , Figure 9 and Figure 10As shown, a positioning rod 617 is fixed to the top of the positioning plate 604, and a limiting plate 621 is fixed to the side of the cleaning plate 614 near the positioning rod 617. A filter plate 613 is inserted between the positioning rod 617 and the limiting plate 621, and a filter screen is provided in the middle of the filter plate 613. Both ends of the filter plate 613 are fixed with pins, and the positioning rod 617 and the limiting plate 621 are provided with insertion holes that are compatible with the pins on the opposite side. The filter plate 613 is inserted between the positioning rod 617 and the limiting plate 621 via pins. The weight of the filter plate 613 is greater than the buoyancy it experiences in the sewage. Pushing the filter plate 613 downward causes it to drive the two pins to be inserted into the insertion holes, thus installing the filter plate 613 on the side of the positioning rod 617 away from the transmission rod 601. Pushing the cleaning plate 614 downward causes the limiting plate 621 to move downward, thus installing the limiting plate 621 on the outside of the pins on the side of the filter plate 613 away from the positioning rod 617.

[0028] refer to Figure 10 and Figure 11 As shown, a waterproof sleeve 615 is also fixed at the bottom of the top cover 2. Two fixing plates 619 are fixed on the outer wall of the waterproof sleeve 615. A secondary barrier block 622 and a main barrier block 616 adapted to the sewage pipe 3 and the dosing pipe 4 are also provided at the ends of the two fixing plates 619 away from the waterproof sleeve 615. The bottom of both the secondary barrier block 622 and the main barrier block 616 is fixed with a lifting rod 620. The bottom of the lifting rod 620 is fixed with a limit plate 621. The lifting rod 620 is inserted into the end of the fixing plate 619 away from the waterproof sleeve 615. The secondary barrier block 622 is located below the sewage pipe 3, and the main barrier block 616 is located below the dosing pipe 4. When the positioning plate 604 moves upward, it drives the filter plate 613 to move upward. The top of the filter plate 613 contacts the bottom of the two limiting plates 621. The filter plate 613 pushes the two lifting rods 620 upward through the limiting plates 621. The two lifting rods 620 respectively drive the secondary barrier block 622 and the main barrier block 616 to move upward, so that the secondary barrier block 622 enters the interior of the sewage pipe 3 and the main barrier block 616 enters the interior of the dosing pipe 4, thereby achieving the sealing of the sewage pipe 3 and the dosing pipe 4.

[0029] refer to Figure 9 , Figure 10 and Figure 11 As shown, a hydroelectric generator 606 is also fixed to the bottom of the sealing disk 618, and the water inlet pipe of the hydroelectric generator 606 extends to the top of the sealing disk 618. The power output terminal of the hydroelectric generator 606 is connected to the servo motor 607 via a wire, and the water outlet terminal of the hydroelectric generator 606 is equipped with a water outlet pipe that extends to the outside of the sewage treatment tank 1. The model of the hydroelectric generator 606 can be referenced from the 10kW impulse hydroelectric generator set produced by Zhenjiang Nengyuan Hydropower Technology Co., Ltd. Both the hydroelectric generator 606 and the servo motor 607 are fixed in the lower half of the sewage treatment tank 1, and are positioned below the sealing plate 618. The sealing plate 618 has a through-hole on its surface, which corresponds to the inlet port of the hydroelectric generator 606, allowing the water filtered by the sealing plate 618 to flow directly into the inlet pipe of the hydroelectric generator 606. Sewage inside the sewage treatment tank 1 is filtered by the filter frame 5 and the filter plate 613 before flowing above the sealing plate 618. The filtered water above the sealing plate 618 flows into the inlet pipe of the hydroelectric generator 606 through the opening. The potential energy generated by the falling filtered water drives the hydroelectric generator 606. The electrical energy generated by the hydroelectric generator 606 is transmitted to the servo motor 607 via wires, providing power to the servo motor 607.

[0030] When the positioning plate 604 rotates and moves upward, the positioning plate 604 drives the positioning rod 617 to rotate and move upward synchronously. The positioning rod 617 drives the filter plate 613 to rotate and move upward synchronously. The filter plate 613 drives the cleaning plate 614 to rotate and move upward synchronously through the limiting plate 621. The cleaning plate 614 contacts the inner wall of the sewage treatment tank 1. The cleaning plate 614 scrapes and cleans the flocculent matter and debris adhering to the inner wall of the sewage treatment tank 1 through its impurity removal inclined surface and in conjunction with the rotation and upward movement trajectory. Meanwhile, as the filter plate 613 rotates and moves upward, it pre-filters the sewage above the filter frame 5 and agitates the sewage, thereby improving the dissolution rate and mixing uniformity of the sewage treatment agent in the sewage.

[0031] Working principle: refer to Figures 1-11As shown, the wastewater requiring treatment is discharged into the wastewater treatment tank 1 through the wastewater pipe 3. Then, the wastewater treatment agent is added into the wastewater treatment tank 1 through the dosing pipe 4. Several filter frames 5 installed inside the wastewater treatment tank 1 filter and intercept flocculent matter and debris generated in the wastewater. The water treated by the filter frames 5 flows to the top of the sealing plate 618. The opening in the sealing plate 618 transports the filtered wastewater to the inlet pipe of the hydroelectric generator 606. The potential energy generated by the falling filtered water drives the hydroelectric generator 606 to operate. The electrical energy generated by the hydroelectric generator 606 is then transmitted through… The wire is fed into the servo motor 607 to provide power to the servo motor 607. The output shaft of the servo motor 607 drives the transmission rod 601 to rotate. The threaded hole on the surface of the transmission rod 601 cooperates with the threaded hole of the collar 612, causing the collar 612 to move upward along the outer wall of the transmission rod 601. The collar 612 drives the positioning plate 604 and the locking rod 611 to move upward. The positioning plate 604 drives the fixing ring 603 to move upward. The locking rod 611 drives the guide ring 605 to move upward synchronously with the fixing ring 603 and the positioning plate 604, thus filtering the sewage inside the sewage treatment tank 1 through the filter frame 5. Furthermore, the positioning plate 604 drives the positioning rod 617 to rotate synchronously and move upward. The positioning rod 617 then drives the filter plate 613 to rotate synchronously and move upward. The filter plate 613 drives the cleaning plate 614 to rotate synchronously and move upward through the limiting plate 621. The cleaning plate 614 is in contact with the inner wall of the sewage treatment tank 1. With the help of its impurity removal slope, the cleaning plate 614 scrapes and cleans the flocculent matter and debris attached to the inner wall of the sewage treatment tank 1. Meanwhile, as the filter plate 613 rotates and moves upward, it pre-filters the sewage above the filter frame 5 and agitates the sewage, accelerating the dissolution rate and mixing uniformity of the sewage treatment agent in the sewage. As the water level inside the sewage treatment tank 1 rises, it can drive the filter frame 5 to move upward. The pre-filtration effect of the filter plate 613 reduces the filtration pressure of the filter frame 5, while achieving full mixing of the sewage treatment agent and sewage in the sewage treatment tank 1.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
