[0002] Due to geological conditions, well structures, and long-term water scouring, sand particles will seep into the well water. In the process of well water extraction and utilization, the mixing of sand particles is a common and thorny problem. These sand particles are easily carried into the water pump and the subsequent water treatment system by the water flow during the pumping process, causing wear on the key components of the water pump such as the impeller and bearings, shortening the service life of the equipment and increasing maintenance costs. At present, although there are some devices for separating well water sand particles on the market, most of them have the following shortcomings: the filter screen that intercepts sand particles is easily blocked by sand particles after long-term use, affecting the flow of water and reducing the transportation efficiency, and cleaning the filter screen requires manual operation, which is time-consuming and laborious.
