Description

TECHNICAL FIELD

[0001] The utility model relates to filter technical field, concretely is a liquid separation structure for preventing filter from being blocked. BACKGROUND

[0002] Sewage refers to the discharge water containing impurities and pollutants generated by living and production activities. This kind of sewage is mainly derived from daily life water, such as kitchen, bathroom and laundry room, etc., which contains a large amount of suspended particles, organic matter, microorganisms and other pollutants. Direct discharge of sewage will cause serious pollution to the environment and destroy the ecological balance. In order to protect the environment and ensure that the discharged water meets the environmental protection standards, the sewage usually needs to be filtered and purified before being discharged. In this process, the filter plays a crucial role, which can effectively separate the solid matter in the sewage, realize solid-liquid separation, and thus prepare for subsequent deep treatment or discharge.

[0003] The patent with publication number CN218529956U discloses a kind of anti-blocking filter, including water inlet, square tank body, base, filter screen, water outlet, cleaning mechanism, anti-blocking mechanism, the lower end of water inlet is fixedly connected with square tank body, cleaning mechanism is arranged on square tank body, four filter screens are slidably connected in square tank body, the lower end of square tank body is fixedly connected with water outlet, the lower end of square tank body is provided with anti-blocking mechanism, the lower end of anti-blocking mechanism is provided with base, the utility model is provided with support plate, baffle, handle and other structures, by pulling handle to drive support plate and baffle to leave tank body, residual dirt on filter screen can be conveniently cleaned, and the filter screen that cannot be used is also convenient to replace.

[0004] Although the above-mentioned technology realizes the left-right horizontal movement of the square tank body through the rotation of the cam and the elastic force of the spring, thereby moving the residual dirt on the filter screen and reducing the risk of filter screen blockage, but this method has certain limitations. When the square tank body moves back and forth, the impurities originally concentrated in a certain area will be evenly distributed on the surface of the filter screen with the movement of the tank body. With the passage of time, the accumulation of such evenly distributed impurities may cause a larger blocked area, thereby reducing the filtering effect. In addition, when the filter screen needs to be cleaned, the impurities on the surface of the filter screen are easy to fall off from the edge due to the movement of the impurities, and these falling impurities may block the water outlet, causing new problems. In view of this, we propose a liquid separation structure for preventing filter from being blocked. UTILITY MODEL CONTENTS
