Description

Technical Field

[0001] This utility model relates to the field of microfoam generation and performance evaluation technology, specifically a microfoam vortex rotation shearing generation device based on magnetic coupling drive. Background Technology

[0002] In the development of microfoam-related application technologies, in order to realize the effective application of microfoam in specific scenarios, it is necessary to ensure its particle size adaptability, generation stability and performance monitorability. At present, there are significant technical shortcomings in the research and control of microfoam generation and performance evaluation in the industry. 1. Insufficient particle size control precision: It is difficult to accurately control the foam particle size to match the size of the key channel structure in the target application scenario, which makes it impossible for the generated foam to enter the fine channel smoothly, affecting the subsequent effect; 2. Insufficient gas-liquid mixing: The mixing method of gas and foaming liquid lacks synergistic optimization design, resulting in insufficient contact and low mixing uniformity. This not only limits foaming efficiency but also easily produces foam with uneven shape, making it difficult to meet the continuous and stable application requirements. 3. Insufficient functional synergy: The foam generation and performance evaluation stages are independent of each other, requiring additional equipment to complete performance testing. It is impossible to obtain stability data in real time during the foam generation process, resulting in a detection lag problem. At the same time, it increases the equipment investment cost and operational complexity. 4. Weak adaptability to extreme working conditions: Under complex environments such as high pressure and high temperature, the observation and analysis components of the existing device are unable to withstand harsh conditions, cannot effectively capture changes in foam morphology and accurately analyze its stability, thus limiting its application expansion in high-requirement scenarios. 5. Poor long-term operational stability: Some devices that rely on specific microporous structures to achieve foam refinement are prone to performance degradation due to structural blockage, requiring frequent shutdowns for maintenance, affecting the continuity of experiments or applications, and reducing overall efficiency. Therefore, developing an integrated experimental device for microfoam generation and performance analysis that can achieve precise microfoam generation, efficient gas-liquid mixing, and simultaneous real-time evaluation of foam stability (especially suitable for high temperature and high pressure conditions) has become a key requirement for solving the above-mentioned industry problems and ensuring the application effect and experimental data reliability of microfoam in scenarios such as core displacement.

[0003] To address the aforementioned problems, the purpose of this invention is to provide a microfoam vortex rotation shearing generation device based on magnetic coupling drive.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a microfoam vortex rotation shearing generation device based on magnetic coupling drive, wherein the microfoam vortex rotation magnetic coupling shearing generation device includes a generator body, a power component, a stirring component, a refining component and a monitoring component; The generator body includes a cylinder, a motor support plate located at the bottom of the cylinder, a foaming liquid inlet at the top of the cylinder, and a micro-foam outlet at the bottom of the cylinder. The power assembly is mounted on the motor support plate, the stirring assembly is located inside the lower part of the cylinder, and the refining assembly is horizontally arranged inside the upper middle part of the cylinder. The power assembly includes a motor, a motor shaft, and a coupling, with the motor shaft mounted on the output end of the motor. The stirring assembly consists of a stirring shaft, a stirring paddle, an inner magnetic clip, and an outer magnetic block. The motor shaft is connected to the stirring shaft of the stirring assembly via a coupling. The stirring paddle is fixed to one end of the stirring shaft by countersunk screws. The inner magnetic clip is installed at the other end of the stirring shaft. The outer magnetic block is correspondingly disposed on the outside of the cylinder.

The refining component is a multi-layer sintered plate structure, which consists of a lower coarse-diameter sintered plate, a middle transition-diameter sintered plate, an upper fine-diameter sintered plate, a No. 2 hexagon socket screw, and a No. 1 flange. The No. 1 flange is fixedly installed on the inner wall of the cylinder. The lower coarse-diameter sintered plate, the middle transition-diameter sintered plate, and the upper fine-diameter sintered plate are fixed to the No. 1 flange on the inner wall of the cylinder by the No. 2 hexagon socket screw. The monitoring component includes a slender viewing window and a high-pressure viewing window. The slender viewing window is disposed on the side wall of the stirring area of ​​the cylinder, and the high-pressure viewing window is installed at the micro-foam outlet of the cylinder. An optical fiber image analysis device is disposed on the outside of the high-pressure viewing window.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

The gas and liquid phases undergo turbulent dissipation in the swirling flow field. Through the synergistic effect of inertial force and viscous force, the gas and liquid achieve pseudo-homogeneous mixing, and the initial nucleation efficiency of bubbles is significantly improved. The non-mechanical stirring fluid dynamic mixing mode reduces the wear rate and energy consumption of the equipment and is suitable for high gas velocity conditions. 2. In this utility model, the gas is injected along the tangential direction of the side wall of the cylinder, forming a rotating flow field, so that the gas and liquid can initially achieve turbulent mixing and improve the gas-liquid contact efficiency; 3. In this utility model, the bottom magnetic stirring system works in conjunction with the tangential airflow field to enhance the uniformity of gas-liquid mixing through the mechanical shearing action of the stirring paddle, ensuring the dispersion of the foam precursor and providing a uniform gas-liquid mixture for the subsequent refining process. 4. In this utility model, the refining component, stirring component, and monitoring component adopt a modular design, and can be quickly disassembled and assembled using standard parts such as hexagonal screws and flanges. For example, the lower coarse-pore sintered plate, the middle transition pore sintered plate, and the upper fine-pore sintered plate can be replaced with components of different pore size combinations according to the target foam particle size requirements. The stirring paddle can also be structurally adjusted to adapt to different gas-liquid ratio scenarios, which greatly improves the scene adaptability and maintenance convenience of the equipment.
