Description

Technical Field

[0001] This application relates to the field of filtration loss reduction agent preparation technology, specifically to an apparatus for preparing filtration loss reduction agents. Background Technology

[0002] Filtration reducer is a chemical agent used in drilling fluids. Its main function is to reduce the filtration loss of drilling fluid. During the drilling process, due to the pressure difference, water will be filtered out through the well wall into the formation, forming a filter cake. The formation of the filter cake can protect the well wall. However, if the filtration loss is too large, it will lead to problems such as well wall instability, shale expansion and collapse. Therefore, controlling the filtration loss is one of the important performance characteristics of drilling fluids.

[0003] Chinese patent CN212440893U discloses a device for preparing a filtration loss reducer. This patent discloses a technical solution for thorough mixing, which solves the problem that existing filtration loss reducers usually require mixing equipment to mix dispersants and petroleum products during processing. Existing mixing equipment can only achieve simple stirring, which is not thorough enough and cannot play a good dispersing role.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: when the device is in use, the telescopic stirring shaft moves continuously in the trajectory of the baffle, which increases the radial sliding mixing of the solvent in the container while it is rotating and mixing, resulting in more uniform dispersion. However, the stirring blade rotates by the centrifugal force of the telescopic stirring shaft, which has low rotation efficiency, reducing the mixing effect and the effect of use. Therefore, a filter loss reduction agent preparation device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a filtration loss reduction agent preparation device with the advantage of convenient rotation. It solves the problem that when the device is in use, the continuous extension and retraction of the telescopic stirring shaft under the trajectory of the baffle increases the radial sliding mixing of the solvent in the container while rotating and mixing, resulting in more uniform dispersion. However, the stirring blade rotates by the centrifugal force of the telescopic stirring shaft, which has low rotation efficiency and reduces the mixing effect and the effect of use.

[0006] To achieve the aforementioned convenient rotation objective, this application provides the following technical solution: a filtration loss reducing agent preparation device, comprising a filtration loss reducing agent preparation device body, a bottom plate disposed on the bottom surface of the filtration loss reducing agent preparation device body, a container fixedly connected to the top surface of the bottom plate, a bearing seat fixedly connected to the inside of the container, and a stirring mechanism for agitating the filtration loss reducing agent;

Through the threaded connection between the screw 19 and the linkage plate 20, the screw 19 drives the connecting ring 21 to move through the linkage plate 20, thereby adjusting the position of the connecting ring 21. The screw 19 is protected by the telescopic sleeve 16.

[0042] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller.

Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0043] The working principle of the above embodiments is as follows:

[0044] The first motor 12 is started, and its output drives the driving bevel gear 11 to rotate. Through the meshing between the driving bevel gear 11 and the driven bevel gear 10, the connecting rod 4 rotates, causing both the mounting rod 8 and the fixing rod 9 to rotate around the connecting rod 4. The dual-axis motor 22 is then started, and through the sliding connection between the positioning plate 28 and the positioning groove 27, its output drives the fixing rod 9 and the mounting rod 8 to rotate. The rubber pad 5 and the container 3 adhere to each other, restricting the support block 7, thus causing the stirring rod 13 to rotate around the fixing rod 9, agitating the liquid. The second motor 14 is then started. The output end drives the screw 19 to rotate. Through the threaded connection between the screw 19 and the linkage plate 20 and the sliding connection between the slide plate 23 and the slide groove 17, the screw 19 drives the connecting ring 21 to move through the linkage plate 20. The position of the connecting ring 21 is adjusted, which in turn drives the mounting rod 8 and the fixing rod 9 to move upward. The container 3 squeezes the support block 7, causing the support block 7 to drive the mounting rod 8 to move, so that the mounting rod 8 is inserted into the mounting hole 18. Through the sliding connection between the positioning plate 28 and the positioning groove 27, the mounting rod 8 is supported, improving the stability of the mounting rod 8. The screw 19 is protected by the telescopic sleeve 16.
