Working principle

HR pistons pushing centrifuge consist of oil-supplying system, product-pushing structure, bearing seat, main shaft, pushing rod, inner drum. outer drum, sieving net, product gathering groove, feeding pipe, washing pipe, housing and other parts. When the drum runs on a full speed driven by the main motor and transmission belt, the suspension will be led to the product distributing plate through feeding pipeline continuously. Then the suspension will be distributed evenly on the filter net on the inner first-grade drum. Most of the liquid phase will be thrown out through the filter net and the filter holes on the drum wall and then drained outside through liquid outlet. The solid will be intercepted on the first -grade drum and form a cake ring. While the drums of the two grades are revolving together at a same speed, the drum of the first grade will move reciprocately continuously in axial by the pushing of the pistons, then the pushing plate will be able to push out the filter cake on the drum of the first grade. In the next step. the filter cake will be pushed into the drum of the second grade to further separate and form a new filter cake. Then, the outer edge of the first-grade drum will push the new filter cake out of the second grade drum continuously. The filtering and washing liquid can be drained out separately if necessary.

Main Characteristics

HR pistons pushing centrifuge is a kind of filter centrifuge that adopts continuously feeding and intermittently pushing out. It can carry all procedures as feeding, separating, washing, discharging and etc on a full speed.

It has the following distinctive features:

1. It can be operated continuously and steadily, which capacity is great.

2. Because of its high separating factor, it can be dehydrated fully in the two drums. So, the filter cake will contain less moist.

3. While there is a high demand to the purity of the products, the centrifuge can wash them and drain out the washing liquid and the mother liquid separately.

4. Low and even consumption of the power.

Using Scope:

This type of centrifuge is well used to separate suspencion with its solid size is over 0.15mm and density is over 40%. It can be used in chemical, light, pharmacy and food industry to produce sodium chloride, ammonium fluoride, ammonium bicarbonate, sodium sulphate, urea, caffeine, polyethylene, polystyrene, oxalate, nitrate

The choice of HR pistons pushing centrifuge

1. if the customer has high requirements on moisture content of filter cake, washing effect and working capapcity.

2. The density of the suspension should be within 30%-80% (weight percentage); the even product particle size is over 0.15mm and its viscosity should be less than 10-1 pa.s

You can choose HR pistons pushing centrifuge concerning above conditions.

Other configuration choices

1. Material: product contact parts can be common stainless steel, special stainless steel, copper alloy, titanium and etc.

2. Motor: you can choose common motor or explosive-proof motor

3. Draining means: you can choose to drain the mother liquid and the washing liquid separately or together.

4. Clearance of the filter net:0.08-0.40mm

5. Can be designed and manufactured according to GMP requirements.

6. Other requirements.
