Filter automatic cleaning structure

Abstract

The invention discloses a filter automatic cleaning structure. The structure includes a filter shell, the inner cavity of the filter shell is provided with an upper partition plate and a lower partition plate, the inner cavity is divided into an upper cavity, a middle cavity and a lower cavity, the upper partition plate is provided with leakage pipe assemblies, and the leakage pipe assemblies comprise tubular permeable bodies, the plurality of leakage pipe assemblies are disposed along spiral path equidistant arrays to form an array set, the outside of the array set is surrounded by several dirt flushing pipes, the lower cavity is divided into a lower inner cavity and a lower outer cavity, the lower inner cavity is internally equipped with a flushing port, the dirt flushing pipes are equipped with dirt flushing holes, the lower ends of the dirt flushing pipes are communicated with the lower outer cavity, the openings of the dirt flushing holes direct to a place beside the array set center, so that the effluent water of the dirt flushing holes can drive the water in the middle cavity to form vortex for scouring. During cleaning, high pressure water is introduced to the flushing port, and water is jetted out from the dirt flushing holes on the dirt flushing pipes to flush the outer walls of the permeable bodies. The filter automatic cleaning structure provided by the invention has the characteristics of high efficiency, low energy consumption and muting, and can be used for filtering and purification of swimming pool water.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a device for filtering and purifying swimming pool water by means of osmosis. Background technique [0002] Swimming pools use a lot of water. For cost reasons, the swimming pool water will not be replaced all the time. Therefore, it is necessary to filter the water in the swimming pool and physically filter the foreign objects and impurities in the water. [0003] Existing swimming pool filtration equipment often uses sand tanks to filter. Generally, a certain scale of quartz sand is placed in the sand tank. The size and specifications of the quartz sand are different within a certain range. In the sand tank, the quartz sand is from top to bottom, from small to The water is arranged in this way. During normal filtration, water enters from the upper layer of sand and comes out from the lower layer. When water flows through the filter layer from above, part of the solid suspended ...
