What are the application advantages and classification of sludge dehydrators?

The new internal structure can enhance the cleaning and heat conduction function, and improve the production efficiency; It is mainly divided into plate and frame type sludge dehydrator, belt type sludge dehydrator, centrifugal type sludge dehydrator and other categories. The following is a detailed introduction of "application advantages and classification of sludge dehydrator".

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 temperature and time can be designed to realize automatic drying. This can save labor and materials and improve work efficiency. It can be used in many types of burners.

3. The new internal structure enhances 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 can reduce the production cost and improve the production efficiency.

2、 Classification of sludge Dehydrators

1. Plate and frame sludge dewatering machine

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 type sludge dewatering machine

The sludge layer is carried by two tensioned filter belts, which pass through a series of regularly arranged rollers in an S-shape. Depending on the tension of the filter belt, the pressure and shear force of the sludge layer are formed, and the capillary water in the sludge layer is squeezed out, so as to realize sludge dewatering.

3. Centrifugal sludge dehydrator

The sludge is fed into the drum by the hollow 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 discharged continuously from the outlet; The liquid in the liquid ring layer is continuously discharged from the weir mouth to the outside of the drum and discharged by gravity.

4. Stacked sludge dewatering machine

The filter body is composed of a fixed ring and a moving ring, and a spiral shaft runs through the filter body. The filtrate is discharged from the filter gap formed by the fixed ring and the movable ring, and the sludge cake is discharged from the end of the dehydration section.
