Technical Field
The application relates to the field of filter presses, in particular to a rotary drum chain belt filter press.
Background
The belt filter press is a dewatering equipment, which has the characteristics of continuous work, large treatment capacity, simple structure, moderate cost and the like, so the belt filter press is widely used for dewatering slurry and slag.
The belt filter press applies pressure to the material mainly comprises two modes of pressing and local rolling. The belt pressing is to spread solid-liquid mixture between the superposed sections of two tensioned annular filter belts, and when two layers of filter belts for clamping materials bypass multi-stage compression rollers with different diameters, the outer layer filter belt wound on the compression rollers generates pressure on the materials between the belts, so that the liquid components are discharged through the filter belts. The belt pressure strength depends on the tension of the belt and the diameter of the passing press roll. The higher the tension is, the higher the pressure of the outer layer belt wound on the compression roller on the material is; when the tension is fixed, the smaller the diameter of the compression roller is, the higher the pressure of the outer layer belt on the material is.
In order to further improve the pressure, when two layers of filter belts pass through the gaps of a plurality of pairs of parallel rollers, the rollers roll materials between the belts, and additional roller pressure is generated on the basis of belt pressure.
But because of the limitation of the tensile stability of the filter belt meshes, the strength of the ring joint and the strength of the high-pressure section small-diameter press roll, the belt pressure generated by the belt tension alone is generally not higher than 0.5 MPa. When parallel rollers are used for generating roller pressure, the pressure application time is short, and the material is easily jammed at the wedge-shaped entering side. In addition, on the belt filter press with several stages of press rolls and several pairs of press rolls, in the whole filter pressing operation, the material can only be pressed for several times (each stage of press rolls and press rolls is 2-3 s) for several seconds in a short time and with low pulsation and strength, and the dewatering effect is poor.
