Natural gas is a kind of important combustible clean energy contained in the formation. During the natural gas exploitation, the raw gas directly produced from the gas well often contains a small amount of sand particles. If these sand particles are not removed, it will seriously affect the service life of the gas transmission system, so it is necessary to use the desander for desanding. After the desander works for a period of time, the accumulated sand particles will block the sand filter hole, so it is necessary to clean the accumulated sand particles. However, the sand cleaning process of the existing desander is time-consuming and laborious, which causes a great burden to the workers. In order to solve this problem, the utility model patent with the application number of  discloses a quick opening natural gas pipeline desander. The features of this natural gas desander are: the hoop structure is used to replace the original bolt connection structure at the blind plate, so as to save the time of cleaning the blind plate and reduce the labor intensity of workers by improving the convenience of disassembly and assembly of the blind plate. However, the improved technical effect is not significant enough, so the utility model also follows the idea of improving the sand cleaning speed to make another improvement on the existing technology.
