[0002] Wastewater refers to the general term for the water discharged during the activities of residents and the runoff rainwater, which includes domestic sewage, industrial wastewater, and other useless water such as the first rainwater runoff into the drainage pipe network. A wastewater filter is a facility for removing harmful substances such as impurities, suspended solids, and microorganisms in wastewater to achieve the purpose of purifying water quality.

[0003] During the wastewater filtration process, some chemical agents are usually added to the wastewater to precipitate the impurities and harmful substances in the wastewater, so as to facilitate better filtration. However, the stirring blades of the existing wastewater filters can only mix and stir in one direction, with low stirring efficiency and poor mixing effect, resulting in incomplete precipitation of impurities and harmful substances, thereby reducing the filtration effect. Secondly, the filter plates of the existing wastewater filters are prone to blockage during use, which will cause the machine to malfunction and need to be dredged, thus reducing the work efficiency. Summary of the Utility Model

[0012] As a further description of the above technical solution:

[0013] An anti-blocking mechanism is arranged on the inner wall of the filter machine main body. The anti-blocking mechanism includes a filter plate and two sliding grooves.

When the first extrusion block is separated from the second extrusion block, the first spring releases its elastic force to drive the first stirring blade and the second stirring blade to move forward, enabling the second stirring blade to reciprocate. Thus, while the first stirring blade stirs, the wastewater can be agitated in another direction, thereby improving the agitation effect of the wastewater, accelerating the reaction rate between the wastewater and the chemical agent, enhancing the filtration efficiency, and enabling the wastewater to be more fully mixed with the chemical agent, improving the purification effect.

[0020] 2.

At the same time, the scraper also contacts the third extrusion block on the filter plate and is extruded by the third extrusion block to move upward in the chute, compressing the second spring. When the scraper is separated from the third extrusion block, the second spring releases its elastic force to drive the scraper to move downward and strike the surface of the filter plate, thereby being able to knock down the impurities stuck in the filter holes of the filter plate, preventing the filter plate from being blocked, and avoiding the impact on work efficiency caused by the need to dredge the filter plate after blockage.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: a waste water filter machine with a circulating filtration function, including a filter machine main body 3. The top of the filter machine main body 3 is respectively connected to a waste water pipe 1 and a liquid adding pipe 2. A stirring mechanism 4 is arranged on the top of the filter machine main body 3. A return pipe 6 is connected to the outer wall of the filter machine main body 3. A fixed seat 8 is connected to the outer wall of the filter machine main body 3. A water pump 7 is connected to the top of the fixed seat 8. One end of the top of the water pump 7 is connected to the return pipe 6, and one side of the water pump 7 is connected to the outer wall of the filter machine main body 3 through a connecting pipe. A water outlet pipe 10 is connected to the outer wall of the filter machine main body 3. A fixed sleeve 9 is connected to the outer wall of the filter machine main body 3. A plurality of support legs 11 are connected to the bottom of the fixed sleeve 9;

[0029] The stirring mechanism 4 includes a first motor 401 and a plurality of second extrusion blocks 410. One side of the first motor 401 is connected to the top of the filter body 3, and one side of the second extrusion block 410 is connected to the inner wall of the filter body 3. The output shaft of the first motor 401 extends into the filter body 3 and is connected to a rotating rod 402. A plurality of grooves are formed on the outer wall of the rotating rod 402, and a first telescopic rod 408 is connected to the inner wall of the groove. The other end of the first telescopic rod 408 is connected to a first stirring blade 405. A first extrusion block 404 is connected to one side of the first stirring blade 405. Second stirring blades 406 are connected to both sides of the first stirring blade 405. A through groove 403 is formed at the top of the first stirring blade 405, and fixing rods 407 are commonly connected to the inner walls of the plurality of through grooves 403 on both sides. A first spring 409 is sleeved outside the first telescopic rod 408, and both ends of the first spring 409 are respectively connected to one side of the first stirring blade 405 and the outer wall of the rotating rod 402.

[0030] The specific implementation method is as follows: By setting the stirring mechanism 4, the rotation of the output shaft of the first motor 401 drives the rotation of the rotating rod 402. The rotation of the rotating rod 402 drives the rotation of the first telescopic rod 408. The rotation of the first telescopic rod 408 drives the rotation of the first stirring blade 405, so as to stir the wastewater in the horizontal direction. While the first stirring blade 405 rotates, it can also drive the first extrusion block 404 to rotate, so that the first extrusion block 404 contacts the second extrusion block 410 on the inner wall of the filter body 3. Since inclined surfaces are provided on one side of both the second extrusion block 410 and the first extrusion block 404, when the first extrusion block 404 contacts the second extrusion block 410, the first extrusion block 404 will be extruded by the second extrusion block 410 and drive the first stirring blade 405 and the second stirring blade 406 to move backward, and the first spring 409 is compressed. When the first extrusion block 404 is separated from the second extrusion block 410, the first spring 409 releases its elastic force to drive the first stirring blade 405 and the second stirring blade 406 to move forward, so that the second stirring blade 406 can reciprocate. Thus, while the first stirring blade 405 stirs horizontally, the wastewater can be agitated in another horizontal direction, thereby improving the agitation effect of the wastewater, accelerating the reaction rate between the wastewater and the chemical agent, improving the filtration efficiency, enabling the wastewater to be mixed with the chemical agent more fully, and improving the purification effect. By the rotation of the output shaft of the second motor 15, the threaded rod 14 rotates. The rotation of the threaded rod 14 drives the threaded plate 12 to move upward, so that the threaded plate 12 can block the filter holes of the filter plate 503, so that the wastewater has enough time to be fully mixed and precipitated with the chemical agent.

[0031] An anti-clogging mechanism 5 is provided on the inner wall of the filter machine main body 3. The anti-clogging mechanism 5 includes a filter plate 503 and two sliding grooves 504. The outer wall of the filter plate 503 is connected to the inner wall of the filter machine main body 3. The sliding grooves 504 are formed on the outer wall of the rotating rod 402. A scraping plate 501 is slidably connected to the inner wall of the sliding groove 504. The bottom of the scraping plate 501 is attached to the top of the filter plate 503. The top of the filter plate 503 is attached to one end of the rotating rod 402. The top of the scraping plate 501 is connected to a second telescopic rod 506. The other end of the second telescopic rod 506 is connected to the inner wall of the sliding groove 504. A second spring 505 is sleeved outside the second telescopic rod 506. Both ends of the second spring 505 are respectively connected to the top of the scraping plate 501 and the inner wall of the sliding groove 504. A plurality of third extrusion blocks 502 are connected to the top of the filter plate 503. Two sliding grooves 16 are formed on the inner wall of the filter machine main body 3. A sliding block 13 is slidably connected to the inner wall of the sliding groove 16. One side of the two sliding blocks 13 is connected to the same threaded plate 12. The outer wall of the threaded plate 12 is slidably connected to the inner wall of the filter machine main body 3. A threaded rod 14 is threadedly connected to the inner wall of the threaded plate 12. Both ends of the threaded rod 14 are respectively rotatably connected to the inner wall of the filter machine main body 3 and the bottom of the filter plate 503. A second motor 15 is connected to the bottom of the filter machine main body 3. The output shaft of the second motor 15 extends into the filter machine main body 3 and is connected to one end of the threaded rod 14.

[0032] The specific implementation method is as follows: By setting the anti-clogging mechanism 5, while the rotating rod 402 rotates, it will also drive the scraping plate 501 to rotate, so as to clean the surface of the filter plate 503 and prevent impurities from accumulating on the surface of the filter plate 503 and causing blockage of the filter plate 503. During the rotation of the scraping plate 501, it will also contact the third extrusion blocks 502 on the filter plate 503. Since one side of the third extrusion block 502 is provided with an inclined surface, the third extrusion block 502 will drive the scraping plate 501 to move upward in the sliding groove 504 through the inclined surface, and at the same time compress the second spring 505. When the scraping plate 501 is separated from the third extrusion block 502, the second spring 505 releases its elastic force to drive the scraping plate 501 to move downward and strike the surface of the filter plate 503, so as to knock down the impurities stuck in the filter holes of the filter plate 503, thereby preventing the filter plate 503 from being blocked and avoiding the need for dredging operations after the filter plate 503 is blocked, which affects the work efficiency.

[0033] Working principle: When in use, wastewater enters the main body 3 of the filter from the wastewater pipe 1. Then, a chemical agent that causes impurities and harmful substances to precipitate is added to the wastewater through the liquid adding pipe 2. At this time, the second motor 15 drives the threaded plate 12 through the threaded rod 14 to block the bottom of the filter plate 503. Then, the first motor 401 is started. The output shaft of the first motor 401 rotates to drive the rotating rod 402, the first telescopic rod 408, and the first stirring blade 405 to rotate, thereby stirring the wastewater. At the same time, the first stirring blade 405 drives the first extrusion block 404 to squeeze with the second extrusion block, so that the first stirring blade 405 and the second stirring blade 406 move backward, and the first spring 409 is compressed. When the first extrusion block 404 is separated from the second extrusion block 410, the first spring 409 releases its elastic force to drive the first stirring blade 405 and the second stirring blade 406 to move forward, enabling the second stirring blade 406 to perform a reciprocating motion. Thus, while the first stirring blade 405 stirs horizontally, the wastewater can be agitated in another horizontal direction, thereby improving the mixing effect of the wastewater and the chemical agent. When the rotating rod 402 rotates, it can clean the surface of the filter plate 503 through the scraper 501. At the same time, it moves upward by contacting the third extrusion block 502, causing the second spring 505 to be compressed. When the scraper 501 is separated from the third extrusion block 502, the second spring 505 releases its elastic force to drive the scraper 501 to move downward, thereby knocking on the surface of the filter plate 503 to prevent impurities from getting stuck in the filter holes and causing the filter plate 503 to be blocked. After the precipitation is completed, the second motor 15 drives the threaded plate 12 to move downward through the threaded rod 14, enabling the wastewater to pass through the filter plate 503 for filtration. Then, the water filtered for the first time is pumped back through the reflux pipe 6 by the water pump 7 for continuous filtration. After the filtration meets the standard, the second motor 15 continues to drive the threaded plate 12 to move downward through the threaded rod 14, enabling the wastewater to flow out from the water outlet pipe 10, thus completing the filtration operation of the wastewater.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
