Vacuum Belt Filter

Horizontal Vacuum Belt filter consists of parts such as rubber filter belt, vacuum chamber, head pulley, rubber belt supporting table, feeding dipper, filter fabrics deviation correction device, driving device, filter fabrics rinsing device, machine rack, etc. It is a highly efficient equipment realizing solid and liquid separation by fully taking advantage of material gravity and vacuum drawing power. Its working principle is as follows:

As shown in the diagram, endless rubber belt continuously moves by motor through reduced speed dragging. Filter fabric is laid on rubber belt and moves with it together. Rubber belt slides and contacts vacuum chamber (there is an endless friction belt between vacuum chamber and rubber belt, forming a water sealing with water entered), and when vacuum chamber connects to vacuum system, vacuum pumping and filtering area is formed on rubber belt; material paste is evenly distributed on filter fabrics by material distributor. Under the working of vacuum, filtering fluids pass through filter fabrics and get together through horizontal grooves on rubber belt, and then enter into vacuum chamber through little holes. Solid granules are blocked and form filter cake. Liquid entering vacuum is discharged by air and water separator. With the movement of rubber belt, the formed filter cakes enters into filter cake rinsing and drying areas in order. At last filter fabrics separates from rubber belt and the filter cake is discharged at the place of unloading filter cake roller. The cleaned filter fabrics after removing the filter cake can be used again. It enters filtering area again after passing through a group of supporting rollers and deviation correction device.
