The backwash water nozzle and the corresponding sewage suction nozzle set on the backwash system, the size and shape of the backwash water nozzle and the sewage suction nozzle are the same. During the backwash process, the water sprayed from the backwash water nozzle is jet-shaped The sewage suction nozzle cannot suck the backwash water and impurities through the filter in time and thoroughly. It needs the backwash system to backwash the filter for many times. Filtration Efficiency and Filtration Effect

The invention specifically relates to a metal membrane differential pressure filter. The purpose is to provide a metal membrane differential pressure filter that combines the backwashing system with the sewage system, discharges backwashing sewage in time, reduces backwashing time, and improves filtration efficiency. The backwash system inside, the transmission system connected to the backwash system, and the sewage system located in the filter system; the backwash system includes a hollow shaft coaxial with the body, and a high-pressure backwash pump is set to flow to the body through the high-pressure backwash pump inlet pipe. For internal water supply, a high-pressure backwashing device with a high-pressure water nozzle is installed on the outside of the fine filter to communicate with the high-pressure water inlet chamber, and the high-pressure water nozzle is inclined to the sewage system; For the sewage discharge device corresponding to the sewage suction port, the opening of the sewage suction port close to the sewage system is larger than the opening close to the high-pressure water inlet chamber. The backwashing process of the present invention is short in duration, low in water consumption, and can quickly restore the initial state.
Description
technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to a metal membrane differential pressure filter. Background technique [0002] The metal membrane differential pressure filter is a comprehensive water treatment equipment. Its main function is to remove suspended solids and particulate matter in the water body, purify the water quality, and reduce the generation of system dirt, bacteria and algae, and rust. [0003] The existing metal membrane differential pressure filter comprises a body, a filter system, a backwash system, a transmission system and a sewage discharge system. The backwash water nozzle and the corresponding sewage suction nozzle set on the backwash system, the size and shape of the backwash water nozzle and the sewage suction nozzle are the same. During the backwash process, the water sprayed from the backwash water nozzle is jet-shaped The sewage suction nozzle cannot suck the backwash water and...
