The belt vacuum filter uses filter cloth as filter medium, and is a filtrating equipment for solid liquid separation by vacuum suction. The whole ring rubber belt is used as a vacuum chamber. The circular belt is driven continuously by the motor, and the filter cloth runs synchronously on the adhesive tape. The adhesive tape is contacted with the annular friction belt on the vacuum slide table and forms a water seal. The slurry is evenly distributed on the filter cloth by the cloth distributor. When the vacuum chamber is connected to the vacuum system, the vacuum zone is formed on the tape, and the filter cloth is collected through the transverse groove on the tape and enters the vacuum chamber by the small hole, and the solid material is intercepted on the filter cloth to form a filter cake. The liquid entering the vacuum chamber is discharged through the steam water separator. With the movement of the rubber belt, the formed filter cake enters the filter cake washing area and the dry area in turn. Finally, the filter cloth is separated from the tape and the filter cake is discharged at the unloading roll. The filter cloth dismantling the filter cake is regenerated after cleaning, and then enters the working area after a set of backup rolls and rectifying devices
Ceramic filter is the world 's most advanced solid-liquid separation technology , with its energy saving, clean and green , you can re-use of resources and other advantages , in various fields of national economy increasingly widely used. Ceramic filter is a good example of successful application of ceramic filtration technology , large-scale promotion in the country in recent years has produced good economic and social benefits. The early 1980s , Outokumpu company successfully developed as a filter medium ceramic filter plates , ceramic filter plate pore size is typically 1 - 5 microns ( the most commonly used is 1.5 - 2.0 microns ) , so microporous capillary action can produce a strong , the ceramic filter to work under the action of the vacuum pump , through the porous liquid-only become filtrate , which is solid and gas -barrier becomes cake filtration plate surface to achieve a solid-liquid separation.
