Introduction to DU type rubber belt vacuum filter equipment:The rubber belt vacuum filter is an efficient separation equipment that uses filter cloth as the filtering medium, fully utilizes the gravity of materials, and relies on negative vacuum pressure as the power to achieve solid-liquid separation.; In terms of structure, the equipment is arranged along the horizontal length direction with consideration sections; Fixed vacuum box is used. The filtration, cake washing, slag unloading, and filter cloth cleaning of the equipment during the production process are continuously completed with the operation of the tape; The equipment can adapt to materials of different concentrations, and the mother liquor and filter cake washing solution can be collected in sections, which has the advantages of high production capacity, high filtration efficiency, good washing effect, and low moisture content of the filter cake. At the same time, ideal parameters can be selected according to production needs for tape speed, feed rate, slurry concentration, washing water volume, vacuum degree, washing zone, and drying zone. The equipment has few vulnerable parts, low failure rate, can achieve long-term continuous operation, smooth operation, easy operation, and low labor intensity. After years of improvement and perfection, the rubber belt vacuum filter has reached the international advanced level of technology and is widely used in industries such as power environmental protection, mining, chemical industry, metallurgy, papermaking, food, pharmaceuticals, and coal.
Working principle of DU rubber belt vacuum filter:The slurry is evenly distributed on the moving filter cloth by the feeding device. Under the filtering effect of the vacuum pump, the filtrate passes through the filter cloth and the tape filter hole into the vacuum box, and then enters the filtrate tank through the connecting pipe at the bottom of the vacuum box. The solid phase is trapped on the filter cloth to form a filter cake. Due to the consistent direction of gravity and vacuum pumping, larger particles settle below the filter cake during settling, while smaller particles settle above the filter cake, forming a structurally sound filter aid layer with low resistance. High filtering speed. The formed filter cake moves with the tape and is washed multiple times, dehydrated, and then falls off at the turning point of the filter cloth. Afterwards, the filter cloth and tape are separated by the driving roller and cleaned and regenerated with high-pressure water. After being adjusted by the correction device, the filter cloth returns to the feeding end to start a new operation cycle.

DU Selection Guide for Rubber Belt Vacuum Filter:1. Select the equipment model based on the solid-liquid ratio, processing capacity, solid particle size, viscosity, and bulk density of the material.
2、 Select the material of the overcurrent component based on the degree of corrosion of the material, and choose the filtering medium based on the solid particle size and material temperature.
3、 For materials containing reactive gases or vapors, semi enclosed and fully enclosed models can be selected.
4、 For materials that need to be washed, downstream or upstream washing can be achieved. For materials that require special washing, a filtration machine should be selected.
5、 It is recommended to conduct small-scale tests on materials that have not been used in the same industry. The processing capacity of PBF belt vacuum filters with the same filtration area is usually 1.2 times that of PBF belt vacuum filters.
6、 The drainage method can achieve high-level or zero position drainage according to the installation height.
