Centrifuges are machines that separate solid particles in a liquid or components in a mixture of liquid and liquid by centrifugal force. In the process of centrifuging, liquid is filtered and discharged through the centrifugal drum body, larger particles are blocked in the inside of the drum body, solid-liquid separation is realized, and some solutions have volatility and combustibility. The suspension to be separated is fed continuously through a feed pipe into the centrifuge, accelerated by a feed distributor and uniformly sprinkled into the first stage drum wall. The liquid part is thrown out of the rotary drum under the action of strong centrifugal force and is discharged along a liquid collecting groove of the housing, and the solid part is trapped on the screen to form a filter cake. The filter cake is washed by the washing liquid, pushed to the discharge end of the rotary drum by the pushing tray, enters the second-stage rotary drum for centrifugal separation, and is discharged out of the machine through the solid collecting tank of the housing.
Because the explosion-proof pushing centrifugal machine has excellent adaptability to liquid-solid separation of materials containing grains, particles and fibers with good filterability, materials which can be successfully separated and widely applied are: nitrocellulose, acetate fibers, sodium chlorate, potassium perchlorate, potassium sulfate, potassium nitrate, and the like.
