Description

Technical Field

[0001] The utility model relates to the technical field of filtering structures, in particular to a filtering device used in a low-pressure pump station. Background Art

[0002] Pump station is a device and project that can provide hydraulic power and pneumatic power with a certain pressure and flow. It is a general term for the water inlet, water outlet, pump room and other buildings of the irrigation and drainage pump station. The most important low-pressure pump equipment is the low-pressure pump equipment, and the low-pressure pump station is usually used in the steel industry when the production water can be recycled or reused after simple treatment.

[0003] The process characteristics of the low-pressure pump station are that the water pressure required by the water supply object is relatively stable, and the water volume also changes with the seasonal temperature changes, but the water supply safety requirements are generally high, the water pump standby rate is large, and the number of water pumps is large. However, during the use of the low-pressure pump station, it was found that the inventor believes that there are some disadvantages: before the low-pressure pump extracts and transports the liquid, the liquid will generally be precipitated in the sedimentation tank to achieve preliminary filtration of the liquid, but it only stops at pretreatment. After the liquid is extracted by the low-pressure pump, the impurities that exist in the liquid to a greater or lesser extent will block the pump station and affect the normal operation of the pump station. The existing low-pressure pump mainly installs a filter screen at the end of the water pipe for filtering. This simple filtering method has a poor filtering effect. Not only is it prone to clogging after a period of time, but it is also unable to effectively intercept the fine iron impurities in the liquid. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Moreover, the filter basket is provided with honeycomb filter holes around its periphery for filtering impurities in the liquid, and a circular ring is fixed on one edge of the filter basket facing the water inlet pipe, and a groove matching the circular ring is provided at the water inlet port.
