Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a sewage purification filter. Background Art

[0002] Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugars, and fat proteins; it also often contains pathogenic bacteria, viruses, and parasite eggs; inorganic salts such as chlorides, sulfates, phosphates, bicarbonates, and sodium, potassium, calcium, magnesium, etc. It is characterized by high nitrogen, sulfur, and phosphorus content, and is prone to generating malodorous substances under the action of anaerobic bacteria.

[0003] A sewage purification filter is proposed in the Chinese utility model patent with the application number 202123238713.6, including a box body, the upper end of the box body is detachably and sealingly connected with a box cover, and a horizontally spread first filter screen and a second filter screen are fixedly arranged inside the box body. The mesh aperture of the first filter screen is smaller than that of the second filter screen, and the first filter screen is located above the second filter screen. A through pipe extending towards the inside of the box body is fixedly connected to the left inner wall of the box body, and a filter layer is fixedly arranged at the right end of the through pipe.

[0020] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a sewage purification filter, including a filter body 1. Inside the filter body 1, a first filter chamber and a second filter chamber are provided. Inside the first filter chamber, a first filter net 12 and a second filter net 13 are clamped. The second filter net 13 is located above the first filter net 12 and cooperates with it. At both ends of the inner wall of the first filter chamber, a second clamping block 16 and a first clamping block 17 are fixedly installed. At both ends of the first filter net 12 and the second filter net 13, a second clamping groove 18 and a first clamping groove 19 are respectively provided. The second clamping groove 18 and the first clamping groove 19 are respectively clamped with the second clamping block 16 and the first clamping block 17. On both sides of the filter body 1, a water injection pipe 5 and a drain pipe 6 are respectively provided. The water injection pipe 5 cooperates with the first filter chamber, and the drain pipe 6 cooperates with the second filter chamber. Inside the filter body 1, a communicating pipe 14 is fixedly connected. Both the first filter chamber and the second filter chamber cooperate with the communicating pipe 14. By setting the size of the first clamping groove 19 to be twice that of the second clamping groove 18, when the staff uses tools to disassemble, maintain or replace the first filter net 12 and the second filter net 13, the situation that the first filter net 12 is stuck inside the first filter chamber will not occur. And during installation, since both the first clamping block 17 and the second clamping block 16 are set in a T shape, after the first filter net 12 passes through the second clamping block 16, it will be clamped with the first clamping block 17 during the continued downward movement. The same goes for the second filter net 13. Thus, the installation and disassembly of the first filter net 12 and the second filter net 13 are very convenient, improving the installation and disassembly efficiency.

[0021] A first sealing cover 2 is threadedly connected to the top of the filter body 1. A second sealing cover 3 is clamped to the top of the filter body 1. A threaded ring 8 is provided on the outside of the first sealing cover 2. A threaded groove matching the threaded ring 8 is provided on the inner wall of the first filter chamber. The threaded groove is threadedly connected to the threaded ring 8. Through the provided threaded ring 8 and motor 9, it is convenient to install and disassemble the first sealing cover 2, so as to maintain and replace the first filter net 12 and the second filter net 13. Inside the second filter chamber, a plurality of partition plates 15 are fixedly installed. The plurality of partition plates 15 are arranged in a wavy shape. By arranging the partition plates 15 in a wavy shape, the time for sewage to pass through the partition plates 15 is longer.

[0022] A motor 9 is fixedly installed at the bottom of the filter body 1. An eccentric roller 10 is rotatably connected inside the filter body 1. A plurality of centrifugal paddles 11 are fixedly connected to the outside of the eccentric roller 10. The eccentric roller 10 penetrates through the first filter net 12 and the second filter net 13 and is rotatably connected to them. Through the cooperation of the provided eccentric roller 10 and centrifugal paddles 11, centrifugal treatment is performed on the sewage during the filtering process. One end of the water injection pipe 5 is fixedly connected with a one-way valve 4. One end of the drain pipe 6 is fixedly connected with a pressure valve 7. Through the provided one-way valve 4, the situation of water backflow will not occur. Through the provided pressure valve 7, the sewage inside the second filter chamber is sucked out. The size of the first clamping groove 19 is twice that of the second clamping groove 18. By limiting its size, it is convenient to install the first filter net 12 and the second filter net 13.

[0023] In summary, when using the sewage purification filter, seal the sealing cover one 2 and the sealing cover two 3, and inject sewage into the interior of the filter body 1 through the water injection pipe 5. Subsequently, after the sewage enters the interior of the filter body 1, filter the impurities contained therein through the arranged first filter screen 12 and the second filter screen 13. The filtering holes of the first filter screen 12 are smaller than those of the second filter screen 13, which is convenient for improving the filtering effect. Then start the motor 9 to drive the centrifugal roller 10 and the centrifugal paddle 11 to operate, and perform centrifugal treatment on the sewage. Subsequently, the sewage enters the interior of the second filter chamber through the connecting pipe 14, contacts the partition plate 15, and contacts the purification materials such as activated carbon filled in the gap between the sewage and the partition plate 15, so as to purify the harmful gases therein and further improve the filtering effect. The flow rate of the sewage is accelerated through the arranged pressure valve 7 and discharged through the drain pipe 6. When it is necessary to maintain and replace the first filter screen 12 and the second filter screen 13, when the staff uses tools to disassemble, maintain or replace the first filter screen 12 and the second filter screen 13, the situation that the first filter screen 12 is stuck inside the first filter chamber will not occur. And during installation, since both the first engaging block 17 and the second engaging block 16 are arranged in a T shape, after the first filter screen 12 passes through the second engaging block 16 and continues to move downward, it will be engaged with the first engaging block 17. The same applies to the second filter screen 13. Therefore, the installation and disassembly of the first filter screen 12 and the second filter screen 13 are very convenient, improving the installation and disassembly efficiency.
