Brush-type self-cleaning filters are suitable for wastewater treatment processes, steel plant slag flushing water, power plant processes and cooling water, papermaking processes and water intake, chemical production processes and irrigation systems, etc., to filter water from 3500-130 micron particle size Various hard particles to ensure the safe and reliable operation of the system. The electric brush-type self-cleaning filter is equipped with multiple filtering and cleaning equipment. When water enters from the filter water inlet and enters the inside of each filter cartridge separately, impurities are intercepted on the inner wall of the filter cartridge, and the filtered clean water flows out from the water outlet. When the impurities on the inner wall of the cylinder accumulate more and more, the pressure difference between the inlet and outlet reaches the preset value or the cleaning time or manual prefabrication, the filter will start the self-cleaning process. The entire self-cleaning process of the brush self-cleaning filter includes two steps: Open the active drain valve on the self-cleaning filter; the motor drives the cleaning system in the self-cleaning filter screen, and the impurities intercepted by the screen are discharged from the drain valve. The system flows continuously during cleaning, and the entire operation process of the self-cleaning filter is controlled by a smart control box equipped with it. The control method can select pressure difference, time, manual and PLC control.
The brush type self-cleaning filter is made of 316L stainless steel sintered filter. It has high strength, high precision and corrosion resistance. The high filtering accuracy can reach 2 microns, which has the characteristics of large processing capacity, long service life and cleaning power. This machine uses intelligent differential pressure control and punctual control to actively clean the filter. When the pressure difference between the inlet and outlet of the filter reaches the set value or the timer reaches the set time, the electric control box announces the signal to drive the motor to roll and the drain valve opens together. The foreign particles sucked on the filter are brushed by the rolling cleaning brush and discharged from the drain valve with the water flow. When the pressure difference between the inlet and the outlet of the filter returns to normal or the timer is set to stop, the motor stops rolling and the electric drain valve shut down. Throughout the process, the materials continued to flow, and successive production was completed.
The brush type self-cleaning filter is mainly composed of a fuselage, a coarse filter, a fine filter, a pressure difference controller, a blowdown valve, a motor or a hydraulic piston, and a stainless steel brush waving a sewage suction device. It has the advantages of simple structure, significant decontamination effect, active sewage discharge, and continuous flow during sewage discharge. It is now widely used in industrial sewage treatment applications. Fully active can be divided into two types: suction nozzle and brush. The suction nozzle driving method is flavor hydraulic driving and motor driving, and the brush driving method is motor driving.
Function and use:
Brush type self-cleaning filter is suitable for wastewater treatment process, steel plant slag flushing water, power plant process and cooling water, papermaking process and water inlet, chemical production process and irrigation system, etc., used to filter 3500-80 micron particles in water Diameter of various hard particles to ensure the system's safe and reliable operation structure and operating principle:
The brush type self-cleaning filter device uses high-strength Johonson filter, which has the characteristics of large processing capacity, long service life and cleaning power. This machine uses pressure difference control and punctual control to actively clean the filter. When the pressure difference between the inlet and outlet of the filter reaches the setting time, the electric control box announces the signal to drive the motor to roll, and the drain valve is opened together. The foreign particles adsorbed on the net are brushed by the rolling steel wire brush and discharged from the drain valve with the flow of water. When the pressure difference between the inlet and outlet of the filter returns to normal or the timer is set to stop, the motor stops running and the electric drain valve closes. Throughout the process, the materials continued to flow, and successive production was completed.
Installation and application:
The brush-type self-cleaning filter can be installed horizontally or straight. When installing the device, please note that the direction of the arrow on the housing must be consistent with the direction of the water flow. When the device is straight, the water flow direction must be from the following. When the pressure difference between the inlet and outlet reaches 0.04MPa At this time, the sewage valve needs to be opened, and the handle is manually rolled to carry out the sewage until the quality of the discharged water becomes clear. The sewage valve is closed, and the system can be performed normally without stopping.
