A filter structure with anti-clogging function

Abstract

The present invention disclosed a filter structure with anti -blocking function, including the installation ring, which has two installation slots symmetrically on both sides of the installation ring.The cover, the fixed connection between the outer filter cover and the inner filter cover, there is a fixed ring, the outer filter cover, inner filter cover and fixed ring slide are connected to the installation slot.In the hole, multiple stitches are slidy in the hole.The present invention sets the external filter cover to half of the state of work and half of the standby state. The pressure difference between the inside and outside of the filter cover when the filter holes are blocked by using the filter holes to drive the rotation of the outer filter cover in the spiny wheel drive structure.Switch and clean up the blocking filter holes, so it can effectively solve the problem of blocking the traditional filter structure after a certain period of time, and maintain long -term stable work without manual cleaning or replacement.

Description

technical field [0001] The invention relates to the technical field of filter nets, in particular to a filter net structure with an anti-clogging function. Background technique [0002] The filter screen, referred to as the filter screen, is a commonly used device for filtering impurities to purify materials. Because it can filter out impurities, it has been widely used in air purification and water filtration. [0003] In terms of air purification, the filter is generally used to filter out large particles of dust and foreign matter. In terms of water filtration, the filter is generally installed at the pump's suction pipe nozzle to filter algae and aquatic plants in the water. The traditional filter structure Generally, there is only one metal mesh. During use, it is easy to cause air purification or water filtration to fail due to blockage. At this time, it is necessary to stop the work, and then remove the filter mesh structure for cleaning or direct replacement. The bl...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: in terms of air purification, the filter screen is generally used to filter out large particles of dust and foreign matter; in terms of water filtration, the filter screen is generally installed in the suction pipe of the water pump The mouth is used to filter algae and aquatic plants in the water body. The traditional filter mesh structure generally only has a metal mesh. During use, it is easy to block the air purification or water body filtration work, and it needs to be stopped at this time. work, and then remove the filter structure for cleaning or direct replacement. Since the blockage of the filter cannot be known in advance, the work of air purification or water filtration will definitely be affected, and frequent replacement is very troublesome, so it is very convenient to use. The inconvenience, the problem that the filter screen is easy to clog cannot be effectively solved
