Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a drilling fluid separation device for drilling. Background Technique

[0002] When using a pile driver for pile driving and drilling, drilling fluid is required. The drilling fluid is bentonite mud with a certain concentration, which plays the roles of carrying slag, lubricating the drill tool, and cooling during the drilling process. And it is necessary to separate and recycle the returned drilling fluid. The particulate matter in the drilling fluid is removed through a separation device to achieve the purpose of recycling. The separation device separates through an internal separation cylinder. A filter screen is arranged on the separation cylinder for separation and filtration. In actual use, the particulate matter easily clogs the fine holes of the filter screen, resulting in a decline in the separation effect of the separation device. And at present, the internal separation cylinder is generally directly fixed on the equipment, which is inconvenient for disassembly and assembly. On the one hand, it is not convenient for centralized cleaning of particulate matter. Secondly, it is not convenient for maintenance and repair of the separation cylinder and the filter screen, and there are certain defects and deficiencies, so improvement is needed.
