1. Prepress-dewatering porous roller
Prepress-dewatering porous roller is that many holes uniformly distributed on the surface of the roller. It is the maximum dehydration roller that the filtered water can be expelled both inside and outside. After the sludge was extruded, the filter cake was initially formed.
2. High pressure dewatering roller
The high-pressure dewatering roller is made up of several rollers of different diameters. The surface of the roller is coated with high-quality natural rubber or PE. Two filter belts are winding between the rollers in a vertical S shape. The diameter of the roller is gradually reduced to form a certain pressure increase, so that the pressure on material increases gradually, a dry filter cake is initially formed through the effect of the extrusion pressure and shear force.
3. Alignment extrusion roller
The filter cake after high-pressure dewatering is still not ideal. In order to achieve maximum solid-liquid separation, it is necessary to extrude through high-strength pinch rolls. Each group of pinch rolls is divided into a fixed roll and a moving roll with airbag pressure. The outer surface of the moving roll is coated with high-quality natural rubber with lower hardness in order to soft contact with the sludge extrusion; adjust the appropriate pressure to ensure the sludge passing and full dehydration.
4. Deviation correcting device
The automatic deviation correcting device is mainly made up of a gas cylinder, solenoid valve, and proximity switch. The device can realize automatic tracking correction. The characteristics are sensitive, reliable, and long service life. The running position of the filter belts keeps stable and centering. The general deviation error is not more than 15mm.
Belt Press Filter Working Principle
The raw material, passing through the distributor, is pre-pressed and dehydrated in the wedge area, and then further squeezed and dehydrated in the large area low pressure drainage area composed of porous drainage rollers. Then, the raw material with a certain degree of dryness is pressed by three sets of high-intensity squeezing, i.e. roller I, roller II and roller III. Then the raw material with extremely low water content is pressed and dehydrated again by the mesh belt at the discharge port. Finally the dry filter cake is discharged. It basically meets the requirements of major varieties for moisture content, and the entire process is subject to extrusion and shear forces.
