Description

Technical Field

[0001] This utility model relates to the field of integrated filter technology, specifically to a self-cleaning integrated filter. Background Technology

[0002] Production and daily life generate a large amount of wastewater. If this wastewater is discharged indiscriminately, it will cause serious environmental pollution. Drinking water, fish, shrimp, crops and other daily necessities closely related to people's lives may also be contaminated. When people drink or eat these contaminated fish, shrimp or crops, it will cause serious harm to their health. Therefore, wastewater needs to be filtered to remove impurities before being discharged. After long-term use, a layer of scale and other impurities often accumulates on the filter and valve core, so the valve core inside the filter needs to be cleaned.

[0003] A search revealed a utility model patent with publication number CN214972017U, which discloses a wastewater filter, including a filter body and a filter cover; the filter body and filter cover are detachably connected by a flange; an inlet pipe is provided on the side wall of the filter body, and a drain pipe is provided at the bottom of the filter body; a filter unit is also provided in the inner cavity of the filter body. This utility model's wastewater filter has multiple sets of filter elements inside, enabling rapid and efficient filtration of wastewater, and the filter elements can be quickly installed and removed while ensuring stable fixation to the filter support plate.

[0004] Although the aforementioned patent has multiple filter elements inside, which can filter sewage quickly and efficiently, and the filter elements can be quickly installed and disassembled while ensuring stable fixation on the filter support plate, the integrated filter will affect its own sealing performance when frequently disassembled and cleaned, and the frequent disassembly and cleaning will result in low practicality of the integrated filter.

[0005] Therefore, it is necessary to propose a self-cleaning integrated filter to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning integrated filter. Through the cooperation of the internal parts of the cleaning mechanism, the dirt on the surface of the filter valve core can be cleaned without disassembling the filter body. Through the cooperation of the internal parts of the sewage discharge mechanism, the cleaning scraper can discharge the cleaned dirt from inside the filter body, thus completing the rapid cleaning of the surface of the filter valve core. This solves the problem that frequent disassembly and cleaning of integrated filters in the prior art will affect the filter's sealing performance and reduce the practicality of integrated filters.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning integrated filter, comprising a filter body, a filter valve core mechanically fixed to the inner wall of the filter body, a cleaning mechanism installed at the top of the filter body, and a sewage discharge mechanism installed at the bottom of the filter body, which is in contact with the outer wall of the cleaning mechanism.

[0008] The cleaning mechanism includes a mounting bracket, which is mechanically fixed to the top of the filter body. A threaded rod is rotatably connected inside the mounting bracket. A cleaning scraper is slidably connected inside the filter body and sleeved with the outer wall of the filter valve core. Connecting rods are mechanically fixed on both sides of the top of the cleaning scraper and penetrate through the filter body to the inside of the mounting bracket.

[0009] The sewage discharge mechanism includes a concave ring, which is installed around the outer wall of the cleaning scraper. A connecting plate is slidably connected to one side of the bottom end of the filter valve core, and fits against the outer wall of the cleaning scraper and extends into the interior of the filter body. A support plate is mechanically connected to the side of the connecting plate away from the cleaning scraper. A support spring is mechanically connected between the support plate and the inner wall of the filter body. A sealing plate is mechanically fixed to one side of the bottom end of the support plate and slides in a sealed manner inside the filter body.

[0010] Preferably, the cleaning mechanism further includes a servo motor, which is fixed to the top of the mounting bracket by bolts. A connecting ring is sleeved on the outer wall of the threaded rod. Limit blocks are mechanically connected to both sides of the connecting ring, which is slidably connected to both sides of the mounting bracket and mechanically connected to the top of the connecting rod.

[0011] Preferably, an inlet pipe is installed on the left side of the filter body, and an outlet pipe is installed at the bottom of the filter body, located between the inner walls of the filter valve core. The mounting bracket and the filter body have movable grooves that match the connecting rod.

[0012] Preferably, the mounting bracket has limiting grooves on both sides that match the limiting block, the inner wall of the connecting ring has an internal thread that matches the external thread of the threaded rod, and the output end of the servo motor is mechanically connected to the top of the threaded rod through a coupling.

[0013] Preferably, a sludge accumulation groove is provided between the concave ring and the outer wall of the cleaning scraper, and the contact surfaces of the concave ring, the outer wall of the cleaning scraper and the connecting plate are all set as conical arc surfaces, and a connecting groove matching the cleaning scraper is opened at the bottom end of the filter body.

[0014] Preferably, the filter body has an internal expansion groove that matches the support plate, connecting plate, and sealing plate. The inner wall of the filter body has a drain port that communicates with the connecting groove, and the outer wall of the sealing plate is connected with a sealing ring around its perimeter, which is sealed to the drain port.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By starting the servo motor, the servo motor drives the threaded rod to rotate. The rotation of the threaded rod drives the connecting ring to rotate through the thread, causing the connecting ring to move on the mounting bracket through the limit block. The movement of the limit block causes the connecting rod to slide up and down inside the mounting bracket and the filter body. The movement of the connecting rod causes the cleaning scraper at the bottom to move, so that the cleaning scraper can scrape and clean the dirt on the outer wall of the filter valve core. Thus, the dirt cleaning operation on the surface of the filter valve core can be completed without removing the filter body.

[0017] As the cleaning scraper moves downwards, the dirt collected in the accumulation groove between the concave ring and the outer wall of the cleaning scraper is collected. At the same time, the cleaning scraper continues to move into the connecting groove and contacts the connecting plate, squeezing the connecting plate. This forces the connecting plate to push the support plate, compressing the support spring and causing it to move. The moving support plate then moves the sealing plate, allowing it to move out from between the connecting groove and the drain port, sealing the connection between them. This allows some wastewater to be discharged from the drain port, which in turn drives the dirt in the accumulation groove out of the drain port. In this way, the cleaning scraper removes the cleaned dirt from inside the filter body, preventing dirt from remaining inside the filter body for a long time. Attached Figure Description

A sealing plate 303 is mechanically fixed to one side of the bottom end of the support plate 304 and slides inside the filter body 1.

[0029] By cooperating with each other among the internal parts of the cleaning mechanism 2, the dirt on the surface of the filter valve core 101 can be cleaned without removing the filter body 1. By cooperating with each other among the internal parts of the drain mechanism 3, the cleaning scraper 207 can discharge the cleaned dirt from inside the filter body 1, thus completing the rapid cleaning of the surface of the filter valve core 101.

[0030] Refer to the instruction manual appendix Figure 1-4The cleaning mechanism 2 also includes a servo motor 202, which is fixed to the top of the mounting bracket 201 by bolts. A connecting ring 204 is sleeved on the outer wall of the threaded rod 203. Limiting blocks 205 are mechanically connected to both sides of the connecting ring 204, and it is slidably connected to both sides of the mounting bracket 201 and mechanically connected to the top of the connecting rod 206. Through the mutual cooperation between the internal parts of the cleaning mechanism 2, the connecting ring 204 can slide on the mounting bracket 201 through the limiting blocks 205.

[0031] Refer to the instruction manual appendix Figure 1-4 An inlet pipe is installed on the left side of the filter body 1, and an outlet pipe is installed at the bottom of the filter body 1, located between the inner walls of the filter valve core 101. The mounting bracket 201 and the filter body 1 have a moving groove that matches the connecting rod 206. The moving groove that matches the connecting rod 206 facilitates the lifting and sliding of the connecting rod 206 inside the mounting bracket 201 and the filter body 1.

[0032] Refer to the instruction manual appendix Figure 1-4 The mounting bracket 201 has limiting grooves on both sides that match the limiting block 205. The inner wall of the connecting ring 204 has an internal thread that matches the external thread of the threaded rod 203. The output end of the servo motor 202 is mechanically connected to the top of the threaded rod 203 through a coupling. By having limiting grooves on both sides of the mounting bracket 201 that match the limiting block 205, the connecting ring 204 can slide on the mounting bracket 201 through the limiting block 205.

[0033] Refer to the instruction manual appendix Figure 1-4 A sludge accumulation groove is provided between the concave ring 301 and the outer wall of the cleaning scraper 207. The contact surfaces of the outer walls of the concave ring 301 and the cleaning scraper 207 with the connecting plate 302 are all set as conical arc surfaces. A connecting groove matching the cleaning scraper 207 is opened at the bottom of the filter body 1. The sludge accumulation groove provided between the concave ring 301 and the outer wall of the cleaning scraper 207, and the contact surfaces of the outer walls of the concave ring 301 and the cleaning scraper 207 with the connecting plate 302 are all set as conical arc surfaces, which facilitates the sliding of the concave ring 301 and the cleaning scraper 207 on the outer wall of the filter valve core 101 to complete the cleaning of dirt on the outer wall of the filter valve core 101, and the cleaned dirt is collected in the sludge accumulation groove.

[0034] Refer to the instruction manual appendix Figure 1-4The filter body 1 has an expansion groove inside that matches the support plate 304, connecting plate 302, and sealing plate 303. A drain port communicating with the connecting groove is opened on one side of the inner wall of the filter body 1. Sealing rings are connected around the outer wall of the sealing plate 303 and are sealed to the drain port. The drain port communicating with the connecting groove is opened on one side of the inner wall of the filter body 1, and sealing rings are connected around the outer wall of the sealing plate 303 and are sealed to the drain port, so that the sealing plate 303 can seal and isolate the connecting groove and the drain port.

[0035] The working principle of this practical application is as follows:

[0036] Refer to the instruction manual appendix Figure 1-4 By starting the servo motor 202, the servo motor 202 drives the threaded rod 203 to rotate. The rotation of the threaded rod 203 drives the connecting ring 204 to rotate through the thread. The connecting ring 204 moves on the mounting bracket 201 through the limit block 205. The movement of the limit block 205 drives the connecting rod 206 to slide up and down inside the mounting bracket 201 and the filter body 1. The movement of the connecting rod 206 drives the cleaning scraper 207 at the bottom to move. The cleaning scraper 207 moves to scrape and clean the dirt on the outer wall of the filter valve core 101. Thus, the cleaning operation of the dirt on the surface of the filter valve core 101 can be completed without removing the filter body 1.

[0037] Refer to the instruction manual appendix Figure 1-4 As the cleaning scraper 207 moves downward, the dirt that can be cleaned is collected in the accumulation groove between the concave ring 301 and the outer wall of the cleaning scraper 207. At the same time, the cleaning scraper 207 continues to move into the connecting groove and contacts the connecting plate 302, squeezing the connecting plate 302. This causes the connecting plate 302 to be pushed by the force to push the support plate 304 to compress the support spring 305 and move. This movement of the support plate 304 drives the sealing plate 303 to move, causing the sealing plate 303 to move out from between the connecting groove and the drain port, sealing and isolating the connecting groove and the drain port. This allows some sewage to be discharged from the drain port, which in turn drives the dirt in the accumulation groove to be discharged from the drain port. Thus, the cleaning scraper 207 can discharge the cleaned dirt from inside the filter body 1, preventing the dirt from remaining inside the filter body 1 for a long time.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
