Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid plugging agent production, in particular to a raw material crushing device for preparing the drilling fluid plugging agent. Background Art

[0002] With the in-depth development of oil fields and the increase in deep, ultra-deep, and complex wells, the problem of lost circulation has become particularly prominent. Loss circulation is mainly caused by plugging materials used in drilling fluids to reduce filtration and protect reservoirs. Lost circulation while drilling agents are added to drilling fluids. Their different levels of plugging particles, fibers, and chips can effectively plug different types of lost circulation formations, quickly and effectively plugging complex formations encountered during drilling and reducing drilling fluid loss. Existing equipment for crushing raw materials for lost circulation agents only has the function of crushing and screening, and is unable to crush large pieces of raw materials. Commonly used crushing rollers are unable to crush large pieces of material, requiring them to be sorted out and crushed, which increases the production time of the lost circulation agent and reduces the crushing efficiency of the raw materials.

[0003] The disclosure (announcement) number is CN216093837U, which discloses a raw material crushing equipment for the preparation of drilling fluid plugging agents, and relates to the technical field of drilling fluid plugging agent production. In view of the problem that the crushing rollers used in the existing plugging agent raw material crushing equipment cannot crush large pieces of materials, and the large pieces of materials need to be picked out separately for crushing, which reduces the efficiency of the plugging agent raw material crushing, the following scheme is proposed, which includes a crushing box and a crushing box, the crushing box side wall is fixedly installed with the crushing box, the top of the crushing box is fixedly installed with a feed hopper and a motor, the top of the crushing box is rotatably installed with a drive rod, the drive rod and the output shaft of the motor are fixedly sleeved with pulleys, and a transmission belt is connected between the two pulleys.

The equipment is complicated to operate the crushing components and the preparation cost is high. At the same time, the cone rod of the crushed raw material repeatedly approaches and hits the inner wall of the crushing box, and the crushing box is easily damaged by the impact. For this reason, we propose a raw material crushing equipment for the preparation of drilling fluid plugging agents. Utility Model Content
