Description

Industrial self-cleaning filter

Technical Field

The utility model relates to a water treatment facilities technical field especially relates to an industry self-cleaning filter.

Background

The self-cleaning filter is special equipment for the filter, which utilizes a filter screen to intercept solid impurities and particles in water, thereby reducing the turbidity of the water and improving the water quality. Water enters the filter from the water inlet, and the filter screen in the filter intercepts impurities in the water. When the sewage on the filter screen reaches a certain degree, the system can automatically open the sewage discharge valve and the sewage discharge mechanism in the machine body to clean the impurities on the filter screen and discharge the impurities out of the machine body, and the impurities do not flow off during the sewage discharge, so that the system is widely used in industrial water treatment, and the conventional self-cleaning filter can be controlled by a remote control box and a remote control device.

Water enters the self-cleaning filter from the water inlet, larger-particle impurities are filtered out by the coarse filter element assembly, then the water reaches the fine filter screen, and after the fine-particle impurities are filtered out by the fine filter screen, clean water is discharged from the water outlet; during the filtering process, the impurities in the inner layer of the fine filter screen are gradually accumulated, and a pressure difference is formed between the inner side and the outer side of the fine filter screen. When this pressure difference reaches a preset value, the automatic cleaning process will start: the blowoff valve is opened, the hydraulic motor chamber and the hydraulic cylinder of the main pipe assembly release pressure and discharge water; the pressure in the hydraulic motor chamber and the sewage suction pipe is greatly reduced, and due to the negative pressure, the sewage on the inner wall of the fine filter screen is sucked by the suction nozzle, flows into the hydraulic motor chamber by the hydraulic motor and is discharged by the sewage discharge valve, so that a sewage suction process is formed. When water flows through the hydraulic motor, the sewage suction pipe is driven to rotate, the hydraulic cylinder piston drives the sewage suction pipe to axially move, and the sewage suction device assembly completely cleans the inner surface of the whole filter screen through the combination of the axial movement and the rotation movement.

But current self-cleaning filter cleaning device only relies on the suction of suction nozzle to absorb the filth of fine filter screen inner wall, and is difficult to clean up adnexed impurity, uses the cleaning brush to clean, remains the filth on the cleaning brush easily, uses the back for a long time, influences the effect of its clearance, and the mesh of thick section of thick bamboo of straining is blockked up by large granule impurity easily, influences its filter effect, and the speed that the rivers advance is slower, and work efficiency reduces.
