Sell second-hand 470 disc centrifugeDisc centrifuge is a type of vertical centrifuge, with a drum mounted on the upper end of a vertical shaft and driven by an electric motor through a transmission device to rotate at high speed. There is a set of disk shaped components nested together inside the drum - discs. There is a small gap between the discs. The suspension (or emulsion) is fed into the drum through a feed pipe located at the center of the drum. When the suspension (or emulsion) flows through the gaps between the discs, solid particles (or droplets) settle onto the discs under the action of the centrifuge, forming sediment (or liquid layer). The sediment slides along the surface of the disc and separates from it, accumulating at the inner diameter of the drum. The separated liquid is discharged from the outlet of the drum. The function of the disc is to shorten the settling distance of solid particles (or droplets) and expand the settling area of the drum. The installation of the disc in the drum greatly improves the production capacity of the separator. The solids accumulated in the drum are manually removed by dismantling the drum after the separator is stopped, or discharged from the drum without stopping through the slag removal mechanism.

Two operations of disc centrifuge:

1. Liquid solid separation (i.e. separation of bottom concentration suspension), also known as clarification operation.

2. Liquid liquid separation (or liquid-liquid solid) separation (i.e. separation of emulsions), also known as separation operation.

Before use, carefully check whether the centrifuge base is securely fastened, whether the machine cover is connected in place, whether all pipelines and clamps are securely connected, whether the lubricating oil level of the gearbox is normal, whether all operating parameters are set within the normal range, and whether water, electricity, compressed air, and steam are supplied normally. Online cleaning; After the production of materials is completed, close the valve of the centrifuge inlet and outlet system pipeline and enter the online cleaning mode; First, use purified water to pre clean the inlet pipeline, drum chamber, outlet pipeline, etc. Then, use a suitable alkaline solution for online cleaning for more than 30 minutes. Use purified water to clean the washing solution thoroughly, so that the pH value of the discharge port reaches neutral.
