ZDG type vacuum belt filter

The r .>
< .> type vacuum belt filter uses filter cloth as the filter medium and makes full use of material gravity and vacuum attraction to achieve solid-state separation. An integral annular rubber belt is used as the vacuum chamber. The annular tape is driven by a motor to run continuously, and the filter cloth is attached to the tape and runs synchronously. The tape contacts the annular friction belt on the vacuum slide and forms a water seal. The slurry is evenly distributed on the filter cloth by the distributor. When the vacuum chamber is connected to the vacuum system, a vacuum filtration area is formed on the tape. The filtrate passes through the filter cloth and collects through the transverse grooves on the tape and enters the vacuum chamber through the small holes. The solid particles are trapped on the filter cloth to form a filter cake. The liquid entering the vacuum chamber is discharged through the steam-water separator. As the rubber belt moves, the filter cake has formed and enters the filter cake washing area and dry cleaning area in sequence. Finally, the filter cloth is separated from the tape. The filter cake is removed in the unloading area, and the filter cloth from which the filter cake is removed is cleaned and re-enters the filter area to enter the next working cycle. r .> <:>
