Abstract

The invention provides a drilling fluid mud negative pressure screening system, which relates to the technical field of drilling fluid treatment, which includes an annular filter belt and a first drive mechanism that drives the filter belt to rotate and vibrate in the circumferential direction. The tensioning mechanism of the filter part of the filter belt is tightened. The upper part of the filter part is provided with a liquid inlet mechanism, and the liquid inlet mechanism is provided with an anti-flush mechanism. The separation device, the gas-liquid separation device and the negative pressure generating device are connected. The solid-liquid separation device includes a cyclone casing and a rotating impeller with gaps arranged in the cyclone casing. The rotating impeller is driven to rotate by the second driving mechanism. A deformed mud scraping mechanism is installed under the rotating impeller. The reducing part can follow the extension of the telescopic cylinder. Long stretch the deformed mud scraping mechanism and drive the deformed mud scraping mechanism to rotate. The problem that the drilling fluid solid-liquid separation equipment occupies a large area and the separation effect is poor in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of drilling fluid treatment, in particular to a drilling fluid mud negative pressure screening system. Background technique [0002] The drilling fluid produced in the process of oil and other energy extraction contains toxic and harmful components such as additives. Direct discharge into the environment will cause environmental pollution, such as polluting surface and groundwater resources. Heavy metals remain in the soil and affect the growth of plants and the reproduction of microorganisms. , At the same time, because of the absorption and enrichment of plants, it will endanger the health of humans and animals. Therefore, before the drilling fluid is discharged, it is necessary to treat the drilling fluid to meet the environmental protection requirements. [0003] Drilling fluid purification in the prior art usually includes: using a vibrating screen to screen large solid particles, and the screened drill...
