This utility model relates to the field of backwash filter technology and discloses a high-pressure pulse backwash filter, including a tank with a high-pressure air
pipe rotatably connected to the top of the tank. This high-pressure pulse backwash filter, through the arrangement of a rotating mechanism, high-pressure air
pipe, and nozzles, operates as follows: When a
drive motor on one side is activated, it drives a top auxiliary gear and a main gear meshing with the auxiliary gear to rotate. This causes the high-pressure air
pipe installed inside the main gear to rotate inside the tank under the drive of the top rotating joint. In conjunction with a
pulse generator on one side, high-pressure gas is delivered to the nozzles. The high-pressure gas is then ejected at high speed in a pulsed form through the inclined injection holes of the nozzles. Because the nozzles are rotating, the ejected high-pressure pulsed
airflow can evenly cover every area of the filter's inner surface, avoiding any dead zones that could affect the normal operation of the device.
