[0002] A scraper centrifuge is commonly used to separate solid and liquid components in a mixture. Its basic principle is to use centrifugal force to separate solid particles from liquid. The operation process includes loading, rotation, separation, and discharge. The centrifuge is usually equipped with a discharge port for the discharge of materials.

[0003] Scraper centrifuges can be used to centrifuge many different types of materials, such as biological samples, chemical reagents, food samples, environmental samples, etc., which have different flow rates during the discharge process, some large and some small. Therefore, the discharge port needs to be designed differently according to the different centrifugal materials to meet the normal discharge of different samples. The discharge port design of traditional scraper centrifuges cannot effectively control the flow rate of the liquid, resulting in uneven sample discharge or the inability to accurately control the sample. Therefore, a scraper centrifuge with a detachable discharge port is proposed to solve the above problems. Utility Model Content
