DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] like Figures 1 to 8As shown, a sewer sewage filter valve includes a filter valve body 1, a filter pipe 2 and a sewage box 3, one end of the filter valve body 1 is connected to the filter pipe 2, a filter mechanism is arranged inside the filter pipe 2, and the filter mechanism includes an annular frame 4 and a filter net 41; a semicircular groove 21 is provided on the filter pipe 2, and mounting frames 22 are arranged on the side walls of both sides of the semicircular groove 21, the annular frame 4 is arranged on the mounting frame 22, and the filter net 41 is inserted into the filter pipe 2 and connected to the annular frame 4; a first opening 24 and a second opening 25 are provided inside the filter pipe 2, and the first opening 24 and the second opening 25 are located on both sides of the filter net 41; the sewage box 3 is fixedly arranged at the bottom of the filter pipe 2, and is connected to the first opening 24 and the second opening 25, and a filter plate 71 is arranged inside the sewage box 3, and the filter plate 71 is arranged at the second opening 25, and the first opening 24 is close to one side of the filter valve body 1.

[0031] Sewage enters the filter tube 2 through the filter valve body 1, and solid particles and impurities in the sewage are filtered through the filter net 41. Larger pollutants in the sewage fall into the sewage tank 3 through the first opening 24 under the action of gravity and are collected; the sewage that enters the sewage tank 3 together with the pollutants flows out from the second opening 25 through the filter plate 71 after filtration, which can effectively collect larger pollutants in the sewage tank 3, reduce the clogging of the filter net 41, and improve the filtering efficiency. At the same time, the sewage tank 3 can be cleaned regularly to clean the pollutants, and the operation is simple.

[0032] The outer walls at both ends of the annular frame 4 are provided with wing plates 5, and the bottom of the wing plates 5 is provided with mounting blocks 51. The two ends of the semicircular groove 21 are provided with mounting seats 6, and the mounting seats 6 are provided with mounting grooves 61. The mounting seats 6 are fixedly connected to the outer peripheral wall of the filter tube 2, and the mounting blocks 51 are adapted to the mounting grooves 61. The side walls of the mounting blocks 51 are provided with card slots 52, and a card block 62 is provided inside the mounting seat 6. One end of the card block 62 passes through the inside of the mounting seat 6 and is connected with a pull rod 63. A first spring 64 is provided inside the card block 62 and the mounting seat 6, and the first spring 64 is sleeved on the pull rod 63. The card block 62 is adapted to the card slot 52, and a second fillet 621 is provided on the side of the card block 62 facing outside the mounting slot 61.

[0033] When the annular frame 4 and the filter screen 41 thereon need to be installed on the filter tube 2, first align the wing plates 5 at both ends of the annular frame 4 with the semicircular grooves 21 on the filter tube 2. The mounting block 51 at the bottom of the wing plate 5 is aligned with the mounting grooves 61 on the mounting seat 6 at both ends of the semicircular groove 21, and then gently pushed in until the mounting block 51 completely enters the mounting groove 61. In this process, the block 62 inside the mounting seat 6 is automatically clamped into the clamping groove 52 of the side wall of the mounting block 51 by the elastic force of the first spring 64, thereby fixing the annular frame 4 and the filter screen 41 to prevent them from being displaced or falling off during operation. When the filter screen 41 needs to be cleaned or replaced, first pull the pull rod 63 to disengage the block 62 from the clamping groove 52. At this time, the annular frame 4 and the filter screen 41 thereon can be easily removed from the filter tube 2 for cleaning or replacement, and at the same time, the second fillet 621 effectively reduces the friction between the block 62 and the mounting block 51 during installation and disassembly, thereby extending its service life.

[0034] The ring frame 4 and the filter screen 41 are stably installed by the mutual cooperation of the wing plate 5, the mounting block 51, the mounting seat 6, the slot 52 and the block 62. The loosening or falling off of the filter screen 41 caused by the impact of water flow or the accumulation of impurities during operation can be effectively prevented, thereby improving the stability and reliability of the filter valve; meanwhile, the disassembly and installation process is simple and quick, which is conducive to maintaining the filtering efficiency and service life of the filter valve.

[0035] A connection block 31 is fixedly arranged inside the sewage box 3, the top of which is connected to the filter tube 2, and the connection block 31 is located between the first opening 24 and the second opening 25. A mounting opening 33 is provided on the outer wall of the sewage box 3, and slots 32 are provided on the inner wall of the sewage box 3 and the side wall of the connection block 31. Both ends of the filter plate 71 are inserted into the slots 32. A sealing plate 7 is arranged on the outer side of the filter plate 71, and the sealing plate 7 is matched with the mounting opening 33. A positioning groove 34 is provided on the side wall of the mounting opening 33, and a positioning block 72 is provided on the side wall of the sealing plate 7. The positioning block 72 extends into the side wall of the sealing plate 7 and is connected to a second spring 74, and the positioning block 72 is matched with the positioning groove 34. A push rod 73 is provided on the outer wall of the sewage box 3, and one end of the push rod 73 passes through the outer wall of the sewage box 3 and extends into the positioning groove 34 to abut against the positioning block 72. The positioning block 72 is provided with a first rounded corner 721 on one side facing the installation opening 33 .

[0036] By setting the connecting block 31, a stable support is provided for the installation of the filter plate 71, so that the filter plate 71 can maintain a stable filtering effect during operation and is not easily disturbed and affected by external factors; by operating the push rod 73, the positioning block 72 compresses the second spring 74 and separates from the positioning groove 34, so that the filter plate 71 can be disassembled and cleaned conveniently, the filtering efficiency can be improved, and the filter plate 71 can be prevented from being blocked; the first fillet 721 set on the positioning block 72 improves the smoothness of the installation and disassembly of the filter plate 71, reduces friction, and prolongs the service life of the device.

[0037] A limiting groove 26 is provided in the filter tube 2 , and the size of the filter screen 41 is adapted to the limiting groove 26 .

[0038] The limiting groove 26 provides an accurate installation position for the filter 41. Since the size of the filter 41 matches the limiting groove 26, the filter 41 can be accurately inserted into the limiting groove 26 to avoid displacement or falling off due to water flow impact or impurity accumulation.

[0039] A sealing ring 23 is provided between the mounting frame 22 and the annular frame 4 .

[0040] By providing the sealing ring 23, the small gap between the mounting frame 22 and the annular frame 4 is filled to prevent sewage or impurities from leaking out through these gaps. The elasticity and sealing performance of the sealing ring 23 enhance the sealing performance of the entire filter valve.

[0041] The working principle of the present invention is as follows: sewage enters the filter tube 2 through the filter valve body 1, and solid particles and impurities in the sewage are filtered through the filter net 41. Larger pollutants in the sewage fall into the sewage tank 3 through the first opening 24 under the action of gravity and are collected; the sewage entering the sewage tank 3 together with the pollutants flows out from the second opening 25 through the filter plate 71 after filtration, which can effectively collect larger pollutants in the sewage tank 3, reduce the clogging of the filter net 41, and improve the filtration efficiency. At the same time, the sewage tank 3 can be cleaned regularly to treat the pollutants. The sewage tank 3 can be made of transparent material, so that the accumulation of pollutants inside the sewage tank 3 can be accurately observed. The discharge port on the sewage tank 3 is opened to clean out the larger pollutants, and the operation is simple.
