According to the specific process requirements, synchronous operation or differential control can be configured. During operation, the heat exchange medium is introduced into the heat exchange medium flow passage cavity 9 formed by the two honeycomb jacket devices 2 through the heat exchange medium circulating driving mechanism 6, and flows directionally in the three-dimensional flow passage formed by the 5 and the bulge part 8. Through the symmetrical arrangement of the jacket, not only the simultaneous and balanced temperature regulation of the left and right sides of the tank body 1 is realized, but also the heat exchange area is increased and the heat transfer effect is strengthened, avoiding the structural stress deformation or local temperature difference fluctuation caused by uneven heating of the tank body. It is beneficial to realize fast, stable and symmetrical heating or cooling response in the process of silica gel dissolution, thereby improving the product dissolution efficiency and temperature control precision. At the same time, the double jacket arrangement also has good modular expansion and maintenance convenience, further enhancing the application reliability and system regulation flexibility of the honeycomb jacket device 2 under complex working conditions.

[0044] Specifically, as shown in the drawings, Figure 1 The tank body 1 includes a dissolution tank body 11, a tank body upper cover 12 connected to the top opening of the dissolution tank body 11, a stirring driving mechanism 13 installed on the tank body upper cover 12, and a stirring fan blade mechanism 14 connected to the output end of the stirring driving mechanism 13 and inserted into the dissolution tank body 11. The dissolution tank body 11 is used to contain silica gel raw materials and dissolution medium. The tank body upper cover 12 is fixedly sealed with the dissolution tank body 11 by flange or sealing connection, thereby forming a closed dissolution space. The stirring driving mechanism 13 is installed on the top of the tank body upper cover 12 and outputs power through a motor or a speed reducer assembly. The output shaft of the stirring driving mechanism 13 penetrates through the tank body upper cover 12 and is coaxially connected with the stirring fan blade mechanism 14. The stirring fan blade mechanism 14 is located inside the dissolution tank body 11 and can be driven to rotate by the stirring shaft. During operation, the stirring driving mechanism 13 drives the stirring fan blade mechanism 14 to rotate, so that the silica gel material and solvent medium in the tank body 1 are fully mixed, sheared and dispersed, effectively promoting the swelling or dissolution of the silica gel, and cooperating with the high-efficiency temperature control function provided by the honeycomb jacket device 2 to realize synchronous heat transfer and dynamic uniform mixing of the material, prevent local caking or uneven dissolution, thereby improving the efficiency, stability and product consistency of the entire silica gel dissolution process.

[0045] The implementation principle of the honeycomb jacket for the silica gel dissolution tank according to the embodiment of the present application is as follows: The honeycomb jacket device 2, the 3 and the jacket outer side plate 4 jointly form a closed cavity for heat exchange; a plurality of 5 are arranged between 3 and the jacket outer side plate 4 for local fixed connection of 3 and the jacket outer side plate 4, 5 are arrayed along the outer surface of the jacket outer side plate 4, and after point welding forming, the point welding grooves 7 are formed at the welding positions, which are concave relative to the jacket outer side plate 4, and at the same time, the non-welding areas between 5 are bulged to form the bulging parts 8 protruding outward after bulging, which are arranged in a honeycomb matrix along the outer surface of the jacket outer side plate 4, so that 3, the jacket outer side plate 4 and 5 form the heat exchange medium flow channel cavity 9 with a three-dimensional channel structure; the heat exchange medium circulating driving mechanism 6 is communicated with the heat exchange medium flow channel cavity 9 for driving the heating or cooling medium to flow through the inside of the heat exchange medium flow channel cavity 9; In the working process, the heat exchange medium is introduced into the heat exchange medium flow channel cavity 9 through the heat exchange medium circulating driving mechanism 6, and flows along the three-dimensional channels formed by the bulging parts 8 in the flow channel defined by 5, the large-area honeycomb array structure of the bulging parts 8 increases the heat exchange contact area and guides the heat exchange medium to form disturbance and multidirectional flow, effectively improving the heat exchange efficiency, avoiding the problem of uneven temperature distribution caused by single flow channel in the traditional jacket, and realizing uniform heating or cooling of the silicone solution process in the tank body 1, thereby preventing problems such as silicone agglomeration, gelation or incomplete dissolution caused by local overheating, and the overall structure is compact, efficient in heat exchange, strong in adaptability and more stable in operation; In the working process, different temperature or different flow rate heat exchange media can be introduced into the first heat exchange cavity 91, the second heat exchange cavity 92 or the third heat exchange cavity 93 by the heat exchange medium circulating driving mechanism 6 to flow, realizing independent temperature control of the local area at different height positions of the tank body 1, making the heating or cooling process more flexible and accurate, and being suitable for the dissolution, dispersion or constant temperature operation of silicone at different temperature stages; the partition heat exchange design avoids the disadvantages of large temperature difference and uneven heat distribution in the traditional jacket whole cavity heat exchange, effectively improves the fine level of heat exchange control, enhances the temperature control function adaptability of the honeycomb jacket device 2, and is beneficial to improving the stability of the overall dissolution process and the product quality.
