Abstract

The invention discloses a drilling fluid mixing and cleaning stirring device and a control method thereof. The drilling fluid mixing and cleaning stirring device includes a driving transmission mechanism, a base and a liquid inlet stirring mechanism. The liquid inlet stirring mechanism includes a mixing transmission device and a stirring rod. The mixing transmission device It includes a liquid inlet pipe and a rotating mechanism. The rotating mechanism includes an inner rotating body and an outer casing. The inner rotating body and the outer casing are rotatably connected by bearings. The outer casing is provided with a first liquid inlet. The side wall of the inner rotating body is provided with a second liquid inlet, the second liquid inlet is a conical liquid inlet, and the small end of the second liquid inlet faces the outside of the inner rotating body, the second liquid inlet The axis of the liquid port intersects the axis of the inner rotating body, and the inner rotating body is connected with a stirring rod through a liquid outlet pipe. By using different control methods, the present invention can realize three functions of stirring, mixing and cleaning, and the stirring effect is good, cleaning Sand is convenient, and the torque of the impeller is small when mixing, which saves energy.

Description

technical field

[0001] The invention relates to the technical field of drilling engineering, in particular to a drilling fluid mixing, cleaning and stirring device and a control method thereof. Background technique

[0002] The mixing and stirring of drilling fluid is an indispensable process in the solids control system. The mixing and stirring is mainly to prevent the drilling fluid from settling. When the drilling fluid density is too small (too high), the drilling fluid is aggravated (diluted) and then the drilling fluid is stirred to make the drilling fluid density in the tank basically constant. The general stirring impeller only has a stirring effect, and cannot fully stir and mix the grit at the bottom of the tank, so that the stirring effect is not ideal; in addition, the tank body in the prior art is generally a cuboid, and the drilling fluid in the corner cannot be stirred and mixed for a long time. If it cannot participate in the circulation operation of the ent...
