AI Technical Summary

Technical Problem

Existing oil drilling fluid storage tanks have the problem of material accumulation on the inner wall and bottom wall of the tank, which leads to the degradation of drilling fluid performance, reduced drilling efficiency, and may cause drilling accidents.

Method used

A coaxial circulating stirring device for a tank is designed. By cooperating with the stirring device and the stirring cage, the material deposited at the bottom of the tank is stirred by the rotating stirring cage and pushed by external force, thereby increasing its fluidity. By controlling the rotation direction of the stirring cage, the material is guided to the dredging port, thereby clearing the silted material.

Benefits of technology

It effectively solves the problem of material sedimentation during drilling fluid mixing, improves work efficiency, reduces manual workload and safety hazards, and improves the performance of drilling fluid and drilling efficiency.

Abstract

The utility model discloses a tank body coaxial circulation stirring device, which relates to the field of petroleum and natural gas exploration drilling fluid service and comprises a shell, a stirring device, a stirring cage, a tank body coaxial circulation stirring device and a tank body coaxial circulation stirring device, the stirring device is vertically arranged in the shell, and liquid can flow in the shell from top to bottom or from bottom to top through the stirring device; the stirring cage is located at the bottom of the shell and is perpendicular to the stirring device, and through rotation of the stirring cage, on one hand, drilling fluid deposition materials deposited at the bottom of the shell are stirred and pushed, so that flowing is increased; the bottom of the shell is provided with a desilting drain outlet. According to the utility model, materials deposited at the bottom can be stirred by rotating the stirring cage, the deposited materials are pushed and extruded by external force to flow, and the materials can be moved in the required direction by controlling the rotating direction of the stirring cage, so that the flowing stirring is realized, and the guiding effect towards a dredging opening is also realized.
