TECHNICAL FIELD

[0001] The application relates to the technical field of circulating tanks, in particular to a circulating tank. BACKGROUND

[0002] In the pharmaceutical industry, the processing of liquid materials is a crucial link in the production process. Whether it is a raw material, an intermediate or a final preparation, the storage, mixing and reaction of liquid materials need to rely on various types of storage tanks and reaction tanks. These devices not only need to meet the basic storage function, but also need to have certain mixing capacity to ensure the uniformity and stability of the drug solution. In addition, due to the particularity and complexity of pharmaceutical production, the safety, stability and cleanliness of the equipment also have very high requirements. In recent years, with the rapid development and technological progress of the pharmaceutical industry, various improved storage tank designs have appeared on the market, but the overall technical level still has certain limitations. Although the traditional storage tank can meet the basic needs, there is still a lot of room for improvement in terms of efficient circulation and pollution prevention.

[0003] At present, the liquid material processing equipment commonly used in the pharmaceutical industry mainly includes fixed stirring tanks, traditional storage tanks with heating jackets and purification tanks with multi-layer filter structures. The fixed stirring tank realizes the full mixing of the drug solution through mechanical stirring, which has the advantages of simple structure and easy maintenance, but also has the problems of high energy consumption and inconvenient cleaning. The traditional storage tank with a heating jacket can control the temperature conditions and is suitable for the processing of heat-sensitive drugs, but its sealing performance often cannot completely avoid the risk of leakage, especially under high temperature and high pressure conditions. Although the purification tank with a multi-layer filter structure can effectively remove impurity particles, it is easy to cause blockage and the cost of replacing the filter material is high. These existing technologies, while meeting the basic needs, also have many shortcomings, especially in terms of fluid continuous flow and homogenization effect.
