The sewage treatment sand removal device includes: a sealed sand removal box; a sealing plate, the sealing plate is arranged on the top of the sealed sand removal box; two slide grooves, the two slide grooves are respectively opened on the inner walls on both sides of the sealed sand removal box; two slide rods, the two slide rods are respectively fixedly installed on the bottom inner walls of the two slide grooves; a filter plate, the filter plate is slidably installed on the two slide rods. The sewage treatment sand removal device provided by the utility model has the advantages of simple operation, convenient collection of sand and gravel, and can enhance the filtering efficiency of sand and gravel to avoid affecting the filtering effect.
以上专利文件中提出的污水处理除砂装置在实际的除砂过程中，由于污水的泥沙和一些杂质在过滤网表面堆积到一定程度后会产生一定的重量，就会对过滤网造成压迫，不仅容易导致过滤网变形，且泥沙会在重力作用下大量堆积并造成滤网堵塞，需要频繁清理滤网才能继续使用。为此，需要对以上装置存在的缺点进行改进。In the actual sand removal process of the sewage treatment sand removal device proposed in the above patent document, the sand and some impurities in the sewage will accumulate to a certain extent on the surface of the filter screen, which will produce a certain weight and cause pressure on the filter screen, which will not only easily cause the filter screen to deform, but also the sand will accumulate in large quantities under the action of gravity and cause the filter screen to be blocked, and the filter screen needs to be frequently cleaned before it can continue to be used. Therefore, it is necessary to improve the shortcomings of the above device.
