Fully automatic cleaning filter (ZQX)

Product Overview

The fully automatic cleaning filter can be used for filtering industrial water, seawater, food and pharmaceutical wastewater, circulating water, as well as emulsion regeneration, waste oil, liquid raw materials and other filtration treatments. In the metallurgical and petrochemical industries, as well as in the water supply and drainage and circulating water systems of power plants and processes involving liquid media filtration, the application of fully automatic cleaning filters is becoming increasingly widespread. Modern metallurgical enterprises in China have introduced continuous casting water systems, blast furnace water systems, high-pressure water descaling systems for hot rolling, emulsion systems, and closed water circulation systems, all of which use self-cleaning filters extensively in liquid media filtration systems.

Product Structure and Working Principle

The fully automatic cleaning filter consists of a main unit and an electronic control system. The filter electrical control system produced by our factory is divided into two series: SIEMENS programming control system and our independently developed electronic control system. The host is composed of a filter body, a filter screen, a reduction motor, a drain valve, a transmission shaft, a differential pressure controller, and other components. The filter body is a flat lid tank, with the upper part being the turbid water area, the middle part being the clear water area, and the lower part being the sewage area. There is an inlet on the upper side, an outlet on the middle side, an electric drain ball valve at the bottom, and a pressure differential controller on the side. There are two types of filter screens: stainless steel dense weave flat mesh and wedge-shaped mesh. The ZQX series fully automatic cleaning filter adopts nylon brush and high-quality carbon steel (stainless steel) cylinder, which has the characteristics of large processing capacity, long service life, and high cleaning efficiency. This machine adopts an efficient, stable, and safe differential pressure control system to automatically clean the filter screen. When the pressure difference between the inlet and outlet of the filter reaches the set value, the control system sends a control signal to drive the motor to rotate and open the drain valve. The sewage outlet forms a vacuum state, and the impurity particles adsorbed on the filter screen are removed by the rotating nylon brush. Wastewater is discharged from the sewage valve. When the pressure difference between the inlet and outlet of the filter returns to normal, the motor stops running and the electric drain valve closes with a delay. Throughout the entire process, the materials did not stop flowing, achieving continuous, automatic, efficient, and safe production.
