Technical Field
[0001] This utility model belongs to the technical field of mixing equipment, and specifically relates to a water-cooled structure and mixing chamber with good sealing effect. Background Technology
[0002] Latex or rubber chemical products are commonly found in industrial production and daily life. During the processing of these products, the adhesive raw materials are prone to generating bubbles inside the adhesive. Due to the high viscosity of the adhesive, the bubbles are difficult to escape from the adhesive on their own. In order to ensure the quality and appearance of the products, these products need to undergo degassing treatment of the adhesive raw materials during processing.
[0003] Degassing mixers are commonly used mixing equipment for basic materials and are the main tools for degassing adhesive raw materials. They are mainly used in the mixing of materials in high-end, sophisticated, and precision fields such as LED, LCD, medical devices, electronic components, nanopowder materials, fine chemical materials, printed electronic materials, electronic packaging materials, and new energy materials. They can achieve mixing of liquid and solid, liquid and liquid, and solid and solid substances.
[0004] For example, the existing patent with application number CN201922055270.3 discloses a direct-drive degassing mixer, including a stirring device, a revolution device, a rotation device, and a direct-drive motor control device. The stirring device includes a stirring table and multiple stirring chambers, which are rotatably mounted on the stirring table. The rotation device includes rotating components, each connected to a corresponding stirring chamber and driving that chamber to rotate. The revolution device is mounted on the stirring table. The direct-drive motor control device includes a revolution direct-drive component and a rotation direct-drive component. The revolution direct-drive component is connected to the stirring table and drives it to revolutionize, while the rotation direct-drive component is connected to the rotating components and drives the multiple stirring chambers to rotate. When the direct-drive motor control device is activated, the revolution direct-drive component drives the stirring table to revolutionize via the revolution device, and the rotation direct-drive component drives the multiple stirring chambers to rotate via the rotating components, thus simultaneously completing the revolution and rotation of the mixer, improving the stirring intensity and efficiency.
[0005] Although the mixer disclosed in the above patent can improve the mixing intensity and efficiency, friction will occur between the chemical materials and the side wall of the mixing chamber during the mixing process, resulting in serious heat generation. The heat can cause the chemical materials to undergo heat-sensitive denaturation.
[0006] To address this issue, existing patent application number CN202420577881.2 discloses a stirring mechanism with a water-cooled structure, including a stirring chamber and a base assembly. The stirring chamber is fixed to the top of the base assembly, and a water-cooling tank is provided at the bottom of the stirring chamber. An inlet and an outlet are provided on the side wall of the base assembly. A first water flow channel and a second water flow channel are provided inside the base assembly. The water-cooling tank is connected to the inlet through the first water flow channel, and the water-cooling tank is connected to the outlet through the second water flow channel, forming a cooling water circuit. This circuit can cool the bottom of the stirring chamber, thereby cooling the chemical materials inside the entire stirring chamber, dissipating the heat of the materials, and preventing the chemical materials from denaturing at high temperatures.
[0007] However, although the water-cooling structure disclosed in the above patent has sealing rings at the inlet and outlet to seal the shaft and the base, the sealing structure is relatively simple and still has the problem of poor sealing effect. Utility Model Content
