Impurity filtering device for industrial sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, and discloses an impurity filtering device for industrial sewage treatment, which comprises a filtering tank, a machine cover is fixedly mounted on the arc-shaped bottom wall surface of the filtering tank, and a servo motor is arranged in the machine cover and fixedly mounted on the bottom wall surface of the filtering tank. According to the impurity filtering device for industrial sewage treatment, the rotary filtering mechanism is arranged, a servo motor drives a rotary column to rotate, a first elastic rod, a bent rod and a second elastic rod drive a filter screen to rotate, rotation of the filter screen for filtering impurities is achieved, rotation of a connecting rod can play a role in rotary stirring on sewage, the filtering efficiency on sewage is increased. Meanwhile, the filter screen can be swung under the action of centrifugal force, and the filter screen has certain elasticity, so that filter screen holes of the filter screen can be enlarged under the action of swinging of the filter screen under the action of centrifugal force, the problem of blockage of the filter screen is avoided, and the industrial sewage filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an impurity filter device for industrial sewage treatment. Background technique [0002] Industrial sewage treatment, as the name implies, is to filter the sewage after industrial production and processing, filter and collect the impurities in it, and then treat the sewage. [0003] The filtering treatment of impurities in industrial sewage in the prior art basically adopts filter-screen filtration. The filter screen can not only facilitate the passage of sewage, but also circulate with impurities when the sewage passes through, so that impurities can be filtered on the filter screen, but a single filter There are many practical problems in the way of the net. First, the filter screen has the problem of being blocked. There are filter holes on the filter screen. The filter screen is a channel for filtering impurities. Once the impurities block the filter holes, the effic...

[0003] The filtering treatment of impurities in industrial sewage in the prior art basically adopts filter-screen filtration. The filter screen can not only facilitate the passage of sewage, but also circulate with impurities when the sewage passes through, so that impurities can be filtered on the filter screen, but a single filter There are many practical problems in the way of the net. First, the filter screen has the problem of being blocked. There are filter holes on the filter screen. The filter screen is a channel for filtering impurities. Once the impurities block the filter holes, the efficiency of the filter screen to filter sewage will be reduced. Second, the filter screen needs to be replaced and cleaned regularly. There are many impurities in industrial wastewater. After using the filter, it needs to be replaced and cleaned regularly by humans in a timely manner, which is time-consuming and laborious, and increases the cost of the enterprise.
