[0002] A large amount of mud will be generated during natural gas drilling. In order to prevent drilling mud from polluting the environment, a series of harmless treatments are required for the mud. The first step is to separate the solid matter such as slag from the mud. Natural gas drilling mud is rich in solid matter and has high viscosity. Traditional screening and filtering devices simply set up filter screens or filter elements to filter the mud to achieve solid-liquid separation. However, when traditional screening and filtering devices are used to screen natural gas drilling mud with high viscosity and rich in solid matter, the mud often passes through the filter screen slowly due to the high viscosity of the mud, and the solid matter blocks the screening filter screen. Therefore, it is necessary to develop a device that can clean up the residual mud. Utility Model Content
