Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drilling fluid centrifuges, in particular to an intelligent control automatic harmful solid phase removing drilling fluid centrifuge. BACKGROUND

[0002] Drilling fluid, also known as mud and flushing fluid, is an essential circulating medium in drilling construction and is the "blood" of drilling. Drilling fluid can be divided into clear water mud, water-based mud, non-water-based mud (commonly known as oil-based mud), and gas drilling fluid according to its composition. After use, drilling fluid will produce certain solid particles in its interior, and most of the solid particles are harmful substances, which will not only affect the normal use of drilling fluid, but also affect the work safety of workers, so it is generally necessary to use a drilling fluid centrifuge to remove harmful solid particles in the drilling fluid.

[0003] A horizontal spiral drilling fluid centrifuge is disclosed in Chinese patent CN216704701U, which relates to the field of drilling fluid equipment. Specifically, it includes a drum outer wall and a drum inner wall, and an impeller is arranged on the drum inner wall.
