Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] like Figures 1 to 6 As shown, a wastewater filter in one embodiment of the present invention includes: a filter cylinder 1, a filter cartridge 2, and a flow guiding and limiting mechanism 3.

[0032] like Figures 1 to 2 As shown, a cover 4 is fixedly installed on the top of the filter cylinder 1, and the cover 4 and the filter cylinder 1 cooperate to form a wastewater filter cylinder. Wastewater can be filtered and guided through the wastewater filter cylinder.

[0033] like Figures 2 to 4 As shown, the filter cartridge 2 is fixedly installed inside the filter cylinder 1, and the outer wall of the filter cartridge 2 and the inner wall of the filter cylinder 1 cooperate to form a filter guide cavity.

[0034] like Figures 2 to 3 As shown, the filter cylinder 2 includes a mesh cylinder 201 and a top ring 202. The mesh cylinder 201 is fixedly disposed below the top ring 202. A limiting boss is integrally formed on the inner wall of the filter cylinder body 1. The limiting boss is used to support the top ring 202.

[0035] like Figures 2 to 3 As shown, a drain pipe 5 and a drain pipe 6 are provided on the outside of the filter cylinder 1. Both the drain pipe 5 and the drain pipe 6 are connected to the filter guide cavity. The drain pipe 5 and the drain pipe 6 are respectively located on the upper and lower sides of the sealing top block 301. The horizontal height of the drain pipe 5 is higher than that of the drain pipe 6.

[0036] like Figures 4 to 6As shown, the flow guiding and limiting mechanism 3 is disposed inside the filter cylinder 1. The flow guiding and limiting mechanism 3 includes a sealing top block 301, a flow limiting block 302, and a lifting control component. The sealing top block 301 is slidably disposed inside the filter cylinder 1 and is located directly below the filter cylinder 2. The flow limiting block 302 is fixedly disposed on the top of the sealing top block 301. The bottom of the screen cylinder 201 can be blocked by the sealing top block 301, so that wastewater can only be discharged through the drain pipe 5 after being filtered by the screen cylinder 201.

[0037] like Figures 3 to 6 As shown, a sealing ring 8 is sleeved on the outer side of the sealing top block 301, and the sealing top block 301 can slide and seal with the inner wall of the filter cylinder 1 under the action of the sealing ring 8.

[0038] like Figures 2 to 5 As shown, the lifting control component is fixedly installed below the sealing top block 301 and is used to control the lifting and lowering of the sealing top block 301. The lifting control component includes a lifting base cylinder 303, a threaded rod 304, a lifting rod 305, a drive shaft 306, a transmission bevel gear 307, and a drive bevel gear 308. The lifting base cylinder 303 is fixedly installed on the inner bottom surface of the filter cylinder 1, and the threaded rod 304 is rotatably assembled inside the lifting base cylinder 303. The lifting base cylinder 303 serves to limit the assembly of the threaded rod 304, and at the same time, the lifting base cylinder 303 can guide the assembly and lifting of the lifting rod 305.

[0039] like Figures 2 to 5 As shown, the lifting rod 305 is threaded onto the outside of the threaded rod 304, and the lifting rod 305 is slidably connected to the lifting base cylinder 303. The lifting rod 305 can be raised and lowered by controlling the rotation of the threaded rod 304 under the action of its internal and external threads. One end of the lifting rod 305 located outside the lifting base cylinder 303 is fixedly connected to the lower surface of the sealing top block 301. The lifting rod 305 allows for the control of the lifting of the sealing top block 301.

[0040] like Figures 2 to 5 As shown, the drive shaft 306 is rotatably mounted below the lifting base cylinder 303 and penetrates through the lifting base cylinder 303. The drive shaft 306 serves to assemble, fix, and drive the rotation of the transmission bevel gear 307. The transmission bevel gear 307 is fixedly sleeved on the outside of the drive shaft 306, and the drive bevel gear 308 is meshed and mounted on one side of the transmission bevel gear 307, and the drive bevel gear 308 is fixedly connected to the lower end of the threaded rod 304. Through the mutual meshing of the transmission bevel gear 307 and the drive bevel gear 308, the rotation of the threaded rod 304 can be controlled, thereby controlling the lifting state of the lifting rod 305.

[0041] Specifically, in practical applications, the drive shaft 306 can be connected to an external drive motor, and the lifting state of the sealing top block 301 can be controlled by driving the drive shaft 306 to rotate through the drive motor.

[0042] like Figure 1 As shown, a wastewater treatment device includes a wastewater filter, a sludge collection box 9, a partition 10, a water collection tank 11, and a liquid addition pipe 12. The partition 10 is fixedly installed inside the sludge collection box 9. The partition 10 divides the sludge collection box 9 into a sludge tank and an assembly tank, and the filter cylinder 1 is fixedly installed inside the assembly tank.

[0043] like Figure 2 As shown, the partition 10 is located below the sewage pipe 6, and the opening of the sewage pipe 6 faces the sludge tank. The sludge discharged from the sewage pipe 6 can be collected and stored through the sludge tank.

[0044] like Figure 2 As shown, the water collection tank 11 is located on one side of the sludge collection box 9, and is correspondingly arranged with the drain pipe 5. The water collection tank 11 serves to collect and store the filtered wastewater discharged from the drain pipe 5. The liquid addition pipe 12 is fixedly installed on the top of the cylinder cover 4 and is connected to the wastewater filter cylinder. Wastewater to be treated can be added to the wastewater filter cylinder through the liquid addition pipe 12.

[0045] In practical use, the wastewater to be treated can be added to the wastewater filter cylinder through the liquid addition pipe 12. After being filtered by the screen cylinder 201, the wastewater is discharged into the water collection tank 11 through the drain pipe 5. When it is necessary to clean the impurities in the screen cylinder 201, the transmission bevel gear 307 can be driven to rotate by controlling the rotation of the drive shaft 306. The threaded rod 304 will rotate synchronously under the meshing action of the transmission bevel gear 307 and the drive bevel gear 308.

[0046] The rotation of the threaded rod 304 causes the lifting rod 305 to descend under the action of the internal and external threads, thereby driving the sealing top block 301 to descend as well. At this time, the bottom of the mesh cylinder 201 is in an open state, and the impurities inside the mesh cylinder 201 can be discharged into the sludge tank for collection along the sealing top block 301 and the sewage pipe 6.

[0047] During the discharge of impurities from the mesh cylinder 201, the impurities can be limited by the flow-limiting block 302 to prevent them from being discharged along the drain pipe 5 and causing blockage. Furthermore, during the sewage cleaning process, the mesh cylinder 201 can be continuously cleaned by supplying clean water to it through the liquid inlet pipe 12. This continuous supply of clean water also helps prevent blockage of the drain pipe 6.

[0048] After the cleaning process, the lifting rod 305 can be raised by controlling the reverse rotation of the drive shaft 306. This allows the sealing top block 301 to re-seal the bottom of the mesh cylinder 201.

[0049] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
