[0024] In order that the object, technical solutions and advantages of the utility model are more clearly and obviously understood, the utility model will be further described in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] It is understood that the above description is only exemplary and is not intended to limit the scope of the utility model.

[0026] The drawings will be described below Figures 1-5 Some embodiments of the utility model provide a catalyst circulating intermediate tank.

[0027] Embodiment 1

[0028] In this embodiment, the catalyst circulating intermediate tank comprises a catalyst tank 100, a distribution pump group 200 and a plurality of worm drives 300. The distribution pump group 200 is connected to the top surface of the catalyst tank 100 in a detachable mounting manner, which facilitates maintenance and cleaning in the later period. The distribution pump group 200 comprises a pump box 210, a conveying pipe 230 and a plurality of shaft paddle discs 220. The shaft paddle discs 220 are rotatably mounted on the inner side of the pump box 210. Each shaft paddle disc 220 comprises a paddle disc 221, a worm gear disc 222 and a plurality of abutting rollers 223 rotatably mounted on the surface of the paddle disc 221. The abutting rollers 223 are distributed along the circumferential direction of the shaft of the paddle disc 221 and are in sliding contact with the surface of the conveying pipe 230. By adjusting the rotating speed of the worm drive 300, the flow rate of the catalyst in each pipe can be accurately controlled, thereby ensuring the efficiency of catalyst distribution and the stability of the reaction process.

[0029] In this embodiment, the worm drive 300 includes a motor and a worm fixed to the output end of the motor, which is in driving engagement with the surface of the worm gear disc 222. The motor adjusts the rotational speed of the shaft paddle disc 220 assembly by controlling the rotational speed of the worm. The catalyst flows through each pipeline via the delivery pipe 230, and the independent control of the flow rate is achieved by adjusting the rotational speed of the worm drive 300. This design ensures that the catalyst is distributed as needed, avoiding the problem of unstable reaction efficiency caused by excessive or insufficient catalyst flow in traditional systems.

[0030] Specifically, the catalyst tank 100 is provided with a filling port 110, and a liquid level sensor 120 is fixedly installed on the bottom surface of the catalyst tank 100. The liquid level sensor 120 is an ultrasonic liquid level sensor. Through this sensor, the liquid level in the catalyst tank can be monitored in real time, ensuring that the amount of catalyst remains within a reasonable range, and avoiding the problems of insufficient catalyst caused by too low liquid level or overflow caused by too high liquid level.

[0031] Embodiment 2

[0032] This embodiment is based on the optimization of embodiment 1, and the main difference lies in the material and design method of the catalyst delivery pipeline.

[0033] In this embodiment, the delivery pipe 230 adopts a silicone hose structure and uses corrosion-resistant silicone material. This design can effectively prolong the service life and avoid corrosion of the pipeline by the catalyst. The elasticity and flexibility of the hose structure also help better adapt to possible vibrations or pressure fluctuations during the flow of catalyst, ensuring flow stability. The gap between the outer periphery of the guide roller 223 and the inner wall of the guide wall 211 is less than or equal to twice the thickness of the delivery pipe 230 wall. Through reasonable gap design, the frictional resistance of the catalyst during delivery is reduced, ensuring efficient operation of the system.

[0034] Further, the guide wall 211 is a semicircular arc surface, and the center of the arc of the guide wall 211 is coaxial with the center of the shaft paddle disc 220. This design not only ensures the smoothness of the catalyst flow, but also reduces the possibility of deviation during the flow of the catalyst, ensuring that the catalyst can be evenly distributed to each pipeline.

[0035] In addition, a fixed shaft rod is fixedly installed inside the pump box 210, and a plurality of shaft paddle discs 220 are arranged in a vertical direction and coaxially arranged on the surface of the fixed shaft rod. This arrangement allows each shaft paddle disc 220 assembly to rotate stably, avoiding the problem of uneven distribution of catalyst caused by axial asymmetry.

[0036] Embodiment 3

[0037] This embodiment further optimizes the design of the fixed points on the inner wall surface of the catalyst tank 100 and the pump box 210 based on embodiment 2.

[0038] As Figure 4 shown, in the present embodiment, the inner wall surface of the catalyst tank 100 and the pump box 210 is provided with a plurality of fixed points of the conveying pipe 230 for fixing the conveying pipe 230, so as to ensure that the conveying pipe 230 maintains a stable fixed position during movement and avoids loosening or falling off. The design of a plurality of fixed points further improves the stability of the system, especially after long-term work, which can effectively prevent the hose from loosening due to friction or mechanical vibration, thereby improving the reliability and safety of the equipment.

[0039] In the present embodiment, the catalyst flows through each pipeline through the conveying pipe 230, and the rotation assembly of the shaft paddle 220 driven by the worm drive 300 enables the catalyst flow in each pipeline to be independently adjusted, meeting the needs of different reaction zones and ensuring the catalytic efficiency and reaction stability during the reaction process.

[0040] Comprehensive effect

[0041] Through the above embodiments, the catalyst circulating intermediate tank provided by the utility model not only has the function of precise flow regulation of the catalyst, but also improves the maintainability and use stability of the equipment. Through the independently driven distribution assembly worm drive 300 and the flexible shaft paddle 220 adjustment mode, the precise distribution of the catalyst in each pipeline is realized, and the maximization of the catalytic efficiency of the reaction zone is ensured. At the same time, the detachable structure, corrosion-resistant material and multi-point fixing design in the design improve the durability and maintenance convenience of the equipment, and solve the problems of uneven distribution of the catalyst, easy damage of the equipment and difficult maintenance in the prior art.
