Introduction to PBF Belt Vacuum Filter Equipment:

PBF Belt Vacuum Filter is a highly automated filtration and separation equipment developed in the 1980s.. This equipment uses filter cloth or mesh as the filtering medium, fully utilizing the gravity of materials and relying on vacuum negative pressure as the driving force to achieve efficient solid-liquid separation; The machine has a unique design and can be divided into sections for filtration, including washing, vibration, hot air drying, and mechanical extrusion, which can solve many problems in the chemical industry. The equipment is structurally arranged with the filtration section arranged along the horizontal length direction; The filtration, cake washing, slag unloading, and filter cloth cleaning during the generation process can be completed continuously; The equipment can adapt to materials of different concentrations, and the mother liquor and filter cake washing solution can be collected in sections, resulting in excellent washing effects. 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 refinement, the PBF belt vacuum filter has been widely used in industries such as environmental protection, mining, chemical, fertilizer, papermaking, food, pharmaceuticals, and metallurgy.

Working principle of PBF belt vacuum filter:

PBF belt vacuum filter is an efficient separation equipment that uses filter cloth as the filtering medium and fully utilizes material gravity and vacuum suction to achieve solid-liquid separation. A detachable filter disc is used as the vacuum chamber, and the filter cloth is continuously operated by the driving roller. At the beginning of the filtration process, the filter disc runs synchronously with the filter cloth in a vacuum state; In a non vacuum state, the filter disc and filter cloth operate relative to each other. The material is evenly distributed on the filter belt of the vacuum filter disc through the slurry distributor, and the slurry on the filter cloth is filtered under the action of vacuum suction. After the vacuum filter disk moves a certain distance, the control system cuts off the vacuum, and the vacuum filter disk quickly returns to its original position under the drag of the cylinder. The filter cloth continues to run under the drag of the driving roller, thus realizing the processes of material mother liquor filtration, filter cake washing, and drying. The filter cake is removed by the scraper device at the discharge point, and the filter cloth is regenerated after cleaning, and then enters the filtration area again through a set of support rollers and correction devices; The filtrate is discharged from the collection tank as it returns with the filter disc.

PBF Belt Vacuum Filter Selection Guide:

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. For materials with poor filtration and high viscosity, thin-layer rapid filtration should be selected. 6. Suggest conducting small-scale experiments on materials that have not been used in the same industry. 7. The drainage method can achieve high-level or zero position drainage according to the installation height.
