Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a silicon carbide inner liner sleeve used in cyclones. Background Art

[0002] A cyclone is a commonly used solid-liquid or liquid-liquid separation device. It achieves solid-liquid or liquid-liquid separation by utilizing the centrifugal force generated by the fluid in a rotating cylinder. A cyclone usually consists of a feed pipe, a rotating cylinder, a discharge pipe, and a waste discharge port. Inside the cyclone, the fluid is introduced into the rotating cylinder to form a rotating circulation. Due to the centrifugal force, the solid particles or liquid with a higher density will settle to the bottom of the cyclone, while the liquid with a lower density will be discharged upward. In this way, effective separation of solid-liquid or liquid-liquid is achieved.

[0003] During the use of the cyclone, an inner sleeve is installed inside the cyclone. The inner sleeve can effectively protect the metal wall of the cyclone from erosion and wear by the fluid, and can also optimize the flow state of the fluid inside the cyclone. Generally, the inner sleeve is connected and positioned in the cyclone by bolts. However, since the internal space of the cyclone is small and the bolt installation requires a certain amount of space and tools, it is easy to be difficult to install. In addition, the bolt installation method may affect the sealing performance of the inner sleeve. If the installation force is not strictly controlled, leakage may occur. At the same time, in some special working environments, the bolts may be corroded, resulting in damage to the bolts or difficulty in unscrewing them, which will increase the difficulty of maintenance.

[0004] Therefore, in response to the above problems, we need to propose a silicon carbide inner liner for use in cyclones. Utility Model Content

Through the movable sleeve 702, the adjusting rod 703 and the limiting shell 704, the movable rod 701 can be displaced through the extrusion plate 705, so as to achieve the function of quickly locking and disassembling the bushing body 5.

[0025] The bottom of the extrusion plate 705 is fixedly connected with a spring 709 , and the bottom of the spring 709 is fixedly connected to the movable shell 8 . The spring 709 is located at the bottom of the extrusion plate 705 , and its function is to extrude the extrusion plate 705 .
