Lws Horizontal Spiral Crude Oil Filtering Decanter Centrifuge

Product Description

Product Description
Horizontal spiral centrifuge is one of our company main products. According to the requirement of the material used, we design the horizontal spiral centrifuge with one motor, two motors driving. At the same time, we design two motors separately on both sides of the machine and motors on the same place of the machine. We also develop three column horizontal spiral centrifuge, used in the separation of coal tar oil, water, slag in the industry, in petrochemical in the separation of oil, water, slag.
Main motor drive at full speed rotating drum, material put into spiral continuously by feed tube, evenly distributed to the spiral discharging port. Under centrifugal force, solid content settles to the drum wall and is pushed out cone drum slag notch by the spiral pusher. Liquid is overflow along the spiral to the drum big end. It form big end set out liquid and small end set out solid.

Feature

In our three phase decanter centrifuges, the light and heavy liquids are discharged via the force of
gravity and the centrifugal force, which effectively prevents the phases mixture and incomplete separation. Ordinary three phase decanter centrifuges often generate incomplete separation because
of unstable light / heavy phase liquid compositions, while in our centrifuges, the interface of light / heavyphase liquids can be regulated with constantly changing material compositions
in the machine working, thus optimal separation effect is achieved. Currently, our three-phase decanter centrifuges are used in the separation of oils, water and slags / dregs in the coal tar industry, the petrochemical industry, the fish powder industry, the swill oil industry, the electrolytic copper industry, and the waste scraps in the slaughter houses.

Material: high quality stainless steel
Bearing: SKF brand. A special selection and arrangement of bearings provides for long life and exceptional reliability
Wear protection: carbide sheets of spiral feeder and replaceable alloy sleeves of drum outlet and spiral feeder outlet

The decanter centrifuge can be adjusted to suit individual requirements by varying:
1. Bowl speed to ensure the exact relative centrifugal force required for optimized separation.
2. Differential speed, for optimized balance between liquid clarity and solids discharge capacity.
3. Pond depth in the bowl for optimized balance between liquid clarity and solid dryness.

Application

The machine is widely used in the production of chemical , printing, metallurgical coal mine, oil production, metallurgy ,iron and steel, fabric ,food, drink, pharmacy starch, dyes and so on, and it can also solve industrial and municipal wastewater. By use it, solid can be dehydrated, liquid can be clarified, etc.

1. Solid phase dehydration: dehydration effect for processing materials of solid particles.
2. Particle size classification: used in the removal of material of large diameter solid particles.
3. Liquid clarification: used for removing solid particles in the suspension liquid are clarified.

We have many appliation in oil separation:

1, animal oil, such as beef oil, pork oil, chicken oil, fish oil , larvae

2, plant oil: sesame oil, soybean oil, sunflower oil, olive oil , avocado ol, ect.

3, waste oil: petroleum oil, tank bottom crude oil, fuel oil, drilling oil ect.

Working principle

Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. The processing material is fed into the bowl through a stationery inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.
