Drum structure and feeding method of fish oil decanter centrifuge

Mar 27, 2018

The fish oil decanter centrifuge is mainly composed of a rotary drum, an auger, a differential, a clutch, a lubrication system, and an elastic foundation. The material to be processed is fed into the feed bin of the screw feeder through a feed pipe of a fish oil decanter centrifuge and rotates at a high speed. Because of the different qualities, the centrifugal force received is different, so the separation effect can be achieved.


Normally, when the rotational speed of a fish oil decanter centrifuge reaches 3000 revolutions per minute, the best solid-liquid separation state can be achieved. In addition, the equipment can maintain continuous and high-efficiency production in the separation processing operation, resulting in high productivity and low energy consumption. The main machine of this equipment is made of stainless steel. The surface of the screw shaft is coated with hard alloy, which is resistant to corrosion and has a long service life.


Next, we mainly introduce the drum structure and feeding method for fish oil decanter centrifuges. Among them, the drum structure has a positive cup type and an inverted cup type, and the corresponding feeding methods include an upper feed material and a lower feed material. At present, the use of inverted cup and under the feeding method. The main reason is that such a structure design shortens the length of the main shaft, simplifies the upper structure, and facilitates slag removal, and it has less pollution to the top during operation. The process piping is centrally arranged below the drum, which is conducive to lifting, overhauling and solving the alpha seal of the drum.


The main working process of a fish oil decanter centrifuge can be described as follows: the material enters the drum from the feed pipe, and the solid particles are accelerated by the centrifugal force to the inner wall of the drum under the action of the centrifugal force field, and the settled particles are in the auger blade. Under the impetus, it is discharged from the settling area through the drying zone to the solid phase outlet; the clarified liquid phase overflows from the overflow hole. In order to achieve solid and liquid automatic, continuous separation.


For users, fish oil decanter centrifuges can be automated, continuous operation, long-term stable operation, and easy maintenance. In addition, the fish oil decanter centrifuge can work under pressure and low temperature, with strong applicability and wide application range.
