What are the advantages and classifications of sludge dehydrators?

The sludge dehydrator is highly dispersed, and the whole system is controlled by computer. The new internal structure can enhance the functions of cleaning and heat conduction; Common classifications include plate and frame sludge dehydrators, belt sludge dehydrators and centrifugal sludge dehydrators. The following describes the "application advantages and classification of sludge dehydrators".

1、 Application advantages of sludge dehydrator

1. Highly dispersed. All material surfaces are effective drying areas, and coal consumption is greatly reduced.

2. The whole system is controlled by computer; According to different drying requirements, different drying temperatures and drying times can be designed to realize automatic drying. This can save labor and materials and improve work efficiency. It can be applied to many types of burners.

3. The new internal structure can enhance cleaning and heat conduction. It has strong adaptability to the moisture and viscosity of materials. The new gear is used to replace the traditional cast steel gear, which not only saves the cost, but also reduces the maintenance cost and drying time.

4. It has a long service life, which can reduce the production cost and improve the production efficiency.

2、 Classification of sludge Dehydrators

1. Plate and frame sludge dehydrator

In the closed state, the sludge pumped by the high-pressure pump is squeezed by the plate and frame, so that the water in the sludge is discharged through the filter cloth to achieve the purpose of dehydration.

2. Belt sludge dehydrator

The sludge layer is entrained by the upper and lower tensioned filter belts, passing through a series of regularly arranged roller cylinders in an S-shape. Relying on the tension of the filter belt itself, the pressing and shear force of the sludge layer is formed to squeeze out the capillary water in the sludge layer, so as to realize sludge dewatering.

3. Centrifugal sludge dehydrator

It is composed of a transfer and a screw conveyor with a hollow rotating shaft. The sludge is sent to the drum by the hollow rotating shaft. Under the centrifugal force generated by high-speed rotation, the sludge is thrown into the drum cavity. Due to different specific gravity, solid-liquid separation is formed. Driven by the screw conveyor, the sludge is transported to the cone end of the drum and continuously discharged from the outlet; The liquid in the liquid ring layer is continuously "overflowed" from the weir mouth to the outside of the drum and discharged by gravity.

4. Stacked sludge dehydrator

The filter main body is formed by a fixed ring and a swimming ring which are superimposed with each other, and a spiral shaft runs through it. Through gravity concentration and the internal pressure formed by the back pressure plate during the propulsion process, the sludge is fully dehydrated, the filtrate is discharged from the filter joint formed by the fixed ring and the movable ring, and the mud cake is discharged from the end of the dehydration section.
