The invention relates to a circulating water medium filtrating system which comprises a water pump, a pneumatic two-position five-way reversing device and a medium filter. The pneumatic two-position five-way reversing device comprises a valve body. A center through hole is formed in the center of the valve body. Five channel holes are sequentially formed in the valve body from top to bottom. An air cylinder is arranged at the top of the valve body. A first lead screw is arranged at the lower end of the air cylinder in a connected mode and provided with an upper piston and a lower piston. The water pump is provided with a first water inlet and a first water outlet. The medium filter is provided with a second water inlet and a second water outlet. The first water outlet communicates with thethird channel hole. The second water inlet communicates with the second channel hole. The second water outlet communicates with the fourth channel hole. According to the circulating water medium filtrating system, the overall structure of the system is greatly simplified, operation is very convenient, fault points are few, the fault rate is low, the control procedure is simple, maintenance is convenient, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a circulating water medium filtration system, which is mainly used in circulating water treatment processes such as swimming pools and bathing pools, and belongs to the technical field of water treatment equipment. Background technique [0002] In the liquid flow operation system with a filter, the liquid is sent to the work site after passing through the filter. After the filter works for a period of time, as the impurity interception increases, the filter may be residually clogged, resulting in equipment damage and production stoppage. Therefore, it is necessary to backwash the filter frequently to effectively remove residues, unblock the pipeline, and ensure smooth production. This device in the prior art is a pipeline system composed of multiple valves. Generally, at least 4 valves need to be activated to switch from normal operation to backwashing. The operation is very troublesome, with many failure points, high failure r...
