An environment-friendly high-efficiency filter device for industrial wastewater

Abstract

The invention discloses an environment-friendly high-efficiency filter device for industrial wastewater, which comprises a base, a filter box, a swing filter box, a first drive motor, a rotating filter cylinder, a second drive motor, special-shaped gears and a liquid outlet. The left and right sides are symmetrically provided with support plates, and the support plates are fixed on the base by screws. The base is provided with a filter box, and the filter box and the base are fixedly connected by bolts. There is a swing seat on the top, and a swing filter box is installed on the swing seat. By indirectly driving the swinging filter box to swing left and right, the filtering speed can be further improved by swinging the swinging filter box left and right, and the flow rate of the liquid can be improved to avoid the situation of liquid blocking holes, and the filtering speed can be greatly improved by secondary centrifugal rotary filtration And the effect of filtration, compared with simple static filtration, the filtration cycle is shorter, which is beneficial to production.

Description

technical field [0001] The invention relates to the field of wastewater filtration, in particular to an environment-friendly high-efficiency filter device for industrial wastewater. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater conta...

AI Technical Summary

Problems solved by technology

For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater contains Contains various pesticides, etc., so preliminary filtration is required during discharge. The existing filtration device only passes through one filtration, and the filtration effect is not good. At the same time, during the filtration process, the traditional static filtration speed is slow and cannot meet the requirements.
