Description

Industrial wastewater filtering device with back flushing mechanism Technical Field The utility model relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater filtering device with a back flushing mechanism. Background Industrial wastewater includes production wastewater, production sewage and cooling water, and refers to wastewater and waste liquid in an industrial production process, wherein the wastewater and waste liquid contain industrial production materials, intermediate products, byproducts which run off along with water, pollutants generated in the production process and the like, and the pollutants in the wastewater not only dissolve pollutants in water, but also contain solid matters such as plastics, branches, gravels and the like which are larger solid pollutants discharged along with the wastewater; However, when the existing industrial wastewater filtering device is used, certain problems exist: The industrial wastewater filtering tank comprises a tank body, an inlet and an outlet which are connected to the tank body, wherein a carrying grille for carrying active carbon is fixed at the lower section of the tank body, and a clamping assembly is arranged on the carrying grille; The filter screen or the filter element of the traditional industrial wastewater filtering device is easy to be blocked by impurities after being used for a long time, so that the filtering efficiency is reduced, the filter screen or the filter element is frequently replaced, the cost is high, the production continuity is also influenced, and the service efficiency of the device is reduced. In view of the above, intensive studies have been conducted to solve the above problems. Aiming at the problems, the novel design is carried out on the basis of the original industrial wastewater filtering device. Disclosure of utility model The utility model aims to provide an industrial wastewater filtering device with a back flushing mechanism, which solves the problems that after a filter screen or a filter element of the industrial wastewater filtering device provided in the background art is used for a long time, the filter screen or the filter element is easy to be blocked by impurities, so that the filtering efficiency is reduced, and the filter screen or the filter element is frequently replaced, so that the cost is high, the production continuity is influenced, and the service efficiency of the device is reduced.
