A filter for water treatment

Abstract

The invention discloses a filter screen for water treatment, which comprises a filter screen body, a rotating rod is connected to the middle part of the filter screen body, a scraping rod is fixed at the end of the rotating rod, and the upper side wall of the filter screen body A motor is fixed, and a belt is set between the driving end of the motor and the rotating rod. The side of the filter body away from the rotating rod is fixed with a trigger tube set vertically on the filter body through a connecting rod. A piston plate 1 and a piston plate 2 slide, a conductive liquid is provided between the piston plate 1 and the piston plate 2, and a telescopic spring is fixed between the side of the piston plate 1 away from the piston plate 2 and the inner wall of the trigger tube, The inner wall of the trigger tube is embedded with two internally connected electric contacts. In the present invention, the operation of the motor is realized according to the amount of impurities on the surface of the filter screen body. The impurities on the surface of the filter screen body affect the normal drainage. When the motor automatically works, the drainage is normal. Finally, stop to ensure that the surface of the filter body is not blocked, and ensure the orderly progress of the water treatment work.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter screen for water treatment. Background technique [0002] Water treatment methods include physical treatment and chemical treatment. Human beings have used water treatment methods for many years. Physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. The most important adsorption method is to use activated carbon for adsorption. The barrier method is to pass water through the filter material, so that the larger impurities cannot pass through, and then obtain cleaner water. [0003] Since water treatment generally goes through the steps of removing relatively large impurities, and is generally carried out through structures such as filter screens, but more impurities can easily block the surface of the filter screen, causing water to fail to pass through,...

[0003] Since water treatment generally goes through the steps of removing large impurities, and is generally carried out through structures such as filter screens, but more impurities are likely to block the surface of the filter screen, making it impossible for water to pass through, which in turn affects the water treatment process
