[0002] In order to improve the sewage treatment environment, some existing sewage purification devices adopt multi-layer filtering devices to filter out pollutants in the sewage, so that the treated sewage meets the discharge standards.

[0003] The components and properties of different sewage are not exactly the same. If completely following a fixed filtration and purification mode, when there are many pollutants, it may not be completely purified, and when there are few pollutants, it will cause waste of filtration and purification materials.

[0004] After retrieval, the patent document with the publication number: CN213924291U provides a sewage purification device, including: a cylindrical box body, in which a first filtering mechanism, a purification mechanism and a second filtering mechanism are sequentially arranged from top to bottom. The first filtering mechanism includes a first motor, an umbrella-shaped filter plate and an annular collection box; the purification mechanism includes a medicine adding box, a partition plate and a second motor; the second filtering mechanism includes a filter screen and a collector; a storage battery for power supply is arranged on the box body.

[0005] In the existing sewage purification devices, the filter screen is easy to be blocked after being used for a long time, inconvenient to clean, and affects the later use.

[0006] To solve the above problems, a sewage purification device is proposed in this application. Content of the Utility Model

Two second external threaded pipes are arranged on the second partition plate. Purification cylinders are threadedly connected to both of the two first external threaded pipes. Filter cylinders are threadedly connected to both of the two second external threaded pipes. A linear pressure mechanism is arranged inside the purification box. Two cleaning mechanisms are connected to the linear pressure mechanism. The two purification cylinders and the two filter cylinders cooperate with the two cleaning mechanisms.

Then the sewage enters between the second partition plate and the first partition plate through the second external thread pipe, and is secondary filtered through the first filter holes. The peculiar smell in the sewage is adsorbed and purified by multiple activated carbon particles. Then the sewage enters above the first partition plate, and the filtered and purified sewage is discharged through the water outlet pipe; double-layer filtration and purification of the sewage can be carried out, improving the sewage purification effect;

[0025] 2. When it is necessary to clean the first filter holes and the second filter holes, the pressure plate is pushed downward by two linear motors. The pressure plate generates pressure on the filtered and purified sewage, making the sewage form a backwashing state. The sewage sequentially enters the interiors of the two purification cylinders through the two first external thread pipes for backwashing, and then enters the interiors of the two filter cylinders through the two second external thread pipes for backwashing. The pressure plate drives the two sliding rods to move downward, and the two sliding rods drive the two cleaning mechanisms to move downward. The cleaning brushes of the four cleaning rings respectively clean the outer sides of the two purification cylinders and the two filter cylinders, improving the cleaning effect;

[0026] The present utility model can perform double-layer filtration and purification of sewage, improving the sewage purification effect, and performing backwashing while cleaning the two purification cylinders and the two filter cylinders, which can improve the cleaning effect.
