Description

Technical Field

[0001] The utility model belongs to the technical field of butterfly separators, and in particular relates to an internal cooling drum of a disc separator. Background Art

[0002] The butterfly separator has a high separation factor and large production capacity. It can process highly dispersed liquid-liquid two-phase turbid liquids and liquid-solid two-phase suspensions with very low solid phase sedimentation velocity that are difficult to be effectively separated by general centrifugal separators, and can process liquid-liquid-solid three-phase mixtures. Therefore, it is widely used in chemical, pharmaceutical, food, petroleum, and bioengineering industries. Since the early days of butterfly separator development, its specifications and varieties are various, and the types of materials it processes are also various.

[0003] With the development of technology, the requirements for separators are getting higher and higher, especially with the rapid development of the biopharmaceutical industry. However, the separation of biological materials has high requirements for temperature, and generally requires low-temperature separation. The butterfly separator uses a high-speed rotation of the drum to achieve rapid separation of materials. The higher the drum speed, the greater the separation factor. In general, the larger the separation factor, the better the separation effect. Especially for materials that are difficult to separate, the separation effect is usually improved by increasing the speed. For the pharmaceutical industry, mycoplasmas, bacteriophages, etc. are often difficult to separate. The drum rotates at a high speed in the separator, and the friction with the surrounding air will generate heat, which will increase the temperature of the material that needs to be separated at low temperature. The higher the speed, the more heat is generated.

[0004] At present, most butterfly separators use a cover cooling structure to exchange heat for the separated materials, but the heat exchange effect of the cover is limited and the temperature control effect is poor, so it is necessary to directly cool the drum to achieve precise temperature control. Utility Model Content

[0005] In view of the above problems, the main purpose of the utility model is to design an internal cooling drum for a disc separator, and to pass a cooling medium into the high-speed rotating drum body to ensure the temperature of the separated materials, thereby solving the technical problems of limited heat exchange effect and poor temperature control effect of the butterfly separator cover.
