The centrifuge can be quickly disassembledand assembled, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of centrifuges, in particular to an extraction centrifuge used for separating liquids with different densities. Background technique [0002] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. The extraction centrifuge is mainly suitable for the separation of liquids with different densities. It has high production efficiency and is widely used in pharmaceutical, chemical, food, environmental protection and other industries. [0003] In the existing extraction centrifuges, the power device generally adopts a suspended structure, the motor is at the top, and is driven from the upper part. The design structure is complex and the center of gravity is high. In some design structures, the motor and bearing seat at the upper end need to be disassembled when adjusting the heavy phase weir plate. Flanges, etc. are very cumbersome. In addition, i...

Problems solved by technology

[0003] In the existing extraction centrifuges, the power device generally adopts a suspended structure, the motor is at the top, and is driven from the upper part. The design structure is complex and the center of gravity is high. In some design structures, the motor and bearing seat at the upper end need to be disassembled when adjusting the heavy phase weir plate. Flanges, etc. are very cumbersome. In addition, in the past, during maintenance, regular maintenance and inspection of extraction centrifuges, all the upper motor and bearing seat flanges must be disassembled before further operation, which is extremely inconvenient to use and easy to clean after cleaning. A lot of cleaning liquid remains in the drum, which is easy to cause material pollution after feeding
