Description

Technical Field

[0001] The present invention relates to the technical field of drilling engineering equipment, and particularly relates to a slurry stirring device for drilling engineering. Background Art

[0002] The slurry stirring device for drilling engineering is an important part of the solid control system of drilling fluid, mainly used for the stirring and mixing of drilling fluid to prevent the deposition of solid particles of drilling fluid in the tank circulation system, ensure the stable performance and uniform mixing of the circulating drilling fluid. The development of this device stems from in-depth research on fluid mechanics, boundary layer separation theory, mixing theory, and wing theory, aiming to improve the mixing performance in the stirring container. Through the rotation of the stirrer, the drilling fluid generates a vortex motion, enhancing the stirring effect and ensuring the efficient utilization of the drilling fluid. During the drilling engineering process, the application of the slurry stirring device is crucial. It can not only improve the drilling efficiency but also reduce equipment failures and maintenance costs, and is an essential device in the drilling engineering field.

[0003] After retrieval, the patent with Chinese patent number CN220918798U discloses a slurry stirring device for drilling engineering, including a box body component with an installation cavity inside; a partition component is arranged in the installation cavity, which divides the installation cavity into an inner cavity and an outer cavity; the stirring components are symmetrically arranged in the inner cavity; the first driving component is arranged in the outer cavity, and its output end is connected to the stirring components; the feeding component is arranged at the opening of the box body component, and its output end penetrates through the box body component to the inner cavity; the blanking component is arranged at the bottom of the inner cavity, and its output end penetrates through the partition component to the outside of the box body component. By arranging symmetrically arranged stirring devices in the inner cavity and setting the stirring ends opposite to each other, the upper and lower liquids can be fully stirred during the stirring process, strengthening the stirring effect; by adding a pump air device and pumping air into the inner cavity, the stirring effect is further enhanced, and at the same time, the structure of piston air pumping is adopted to achieve an adjustable effect. Compared with the prior art, the patent with Chinese patent number CN220918798U solves the problems that in the existing drilling engineering site, the motor is usually fixed on a steel barrel-shaped container as a stirring device, which is simple and practical in structure but bulky and not conducive to handling; in addition, the addition amount of additives is not easy to control, easily causing material waste and unstable performance of the drilling fluid.

By using the technology of the present invention, the side walls and bottom of the mixing barrel are kept clean, the uniformity of slurry mixing is significantly improved, the stability of the wall protection agent is increased, and the mixing time is greatly shortened.
