DI floating disc vacuum filter is a vacuum filtering equipment with high efficiency and wide application fields. It mainly consists of feeding device, filter cake washing device, vacuum chamber (filter plate), driving roller, filter belt, filter cloth tensioner, filter cloth guide device, filter cloth washing device, drive device, vacuum switch valve, gas control box, discharging device, etc. While working, vacuum chamber (filter plate) is moving flatly together with filter belt, at the same time operating filtering, washing, dewatering, discharging filter cake etc.; when vacuum chamber (filter belt) move to a certain position, because of the action of gas control system and vacuum switch valve, it removes the vacuum, then returns to the initial position rapidly to restore vacuum and takes filter belt to continue moving forward. It runs in cycle like this.
II. Product Advantage
1. performance advantage
High filtering efficiency, good filter cake washing effiect, filter cloth recycling thoroughly, flexible operation, low maintenance cost. For filter cake washing way, can use multistage counter-current or cocurrent flow. It especially suitable for technical process with faster sedimentation velocity and that filter cake needing multistage wash.
2. allocation advantage
1). The patented technology of vacuum automatic balanced drainage system. It doesn't need to control and discharges liquid automatically. Two models A and B to choose.
2). New filter belt with automatic speedy correction device.
3). New filtrate collecting system.
4). Gas control switching system. Switch fast, act accurately.
5). Special vacuum sealing device. Good seal performance, long service life.
