分配阀33采用平面接触式,通过分配阀33上的分区使过滤盘31各部分处在不同的工作状态: The distribution valve 33 adopts a flat contact type, and the various parts of the filter disc 31 are in different working states through the partitions on the distribution valve 33:
主轴带动过滤盘31转动,当一个扇形板32浸入液面下时,通过扇形板32的水形成真空浊滤液,多圆盘过滤机3槽体中的纤维和填料吸附到滤网上,形成一个纤维垫层,在这一区域,一小部分纤维和填料与滤液一起穿过滤网,形成一种浑浊的滤液,称为浊滤液区,通过排液管排到浊水池5,浊水池5的浊白水可用于冲刷接料斗和稀释输出浆料; The main shaft drives the filter disc 31 to rotate. When a fan-shaped plate 32 is immersed in the liquid surface, the water passing through the fan-shaped plate 32 forms a vacuum filtrate. Cushion, in this area, a small part of fibers and fillers pass through the filter screen together with the filtrate to form a turbid filtrate, called the turbid filtrate area, which is discharged to the turbid water pool 5 through the drain pipe, and the turbid white water in the turbid water pool 5 It can be used to flush the receiving hopper and dilute the output slurry;
主轴继续转动,这时过滤盘31上的纤维垫层已达到一定的厚度,起过滤介质的作用,在真空抽吸作用下,滤液中的纤维和填料被吸附到垫层上,此时在分配阀33内部处于真空区,穿过滤网的固形物大大降低,形成一种澄清的滤液,称为清滤液,该清滤液排入清滤液池,这部分滤液可用于洗网剥浆; The main shaft continues to rotate. At this time, the fiber cushion layer on the filter disc 31 has reached a certain thickness and acts as a filter medium. Under the action of vacuum suction, the fibers and fillers in the filtrate are adsorbed on the cushion layer. The inside of the valve 33 is in a vacuum area, and the solids passing through the filter screen are greatly reduced to form a clear filtrate, called the filtrate, which is discharged into the filtrate pool, and this part of the filtrate can be used for net washing and depulping;

主轴继续转动,真空作用逐渐消失,进入剥浆区(即大气区),这时过滤盘31两侧的喷淋装置喷出的扇形水流开始剥落浆层,在自身重力的作用下,卷落入接料斗中,由冲浆管水流冲到出料口并稀释; The main shaft continues to rotate, the vacuum effect gradually disappears, and enters the peeling area (that is, the atmospheric area). At this time, the fan-shaped water flow sprayed by the spray devices on both sides of the filter disc 31 begins to peel off the pulp layer. In the receiving hopper, the water flow from the flushing pipe rushes to the discharge port and dilutes;
过滤盘31转动到洗网区,该区与大气相通,由摆动喷淋装置的喷嘴喷出的水流使滤网再生,恢复过滤能力后的滤网再进入下一个过滤周期,就这样,随着过滤盘31连续的转动,使扇形板32工作在不同的区间,产生连续的过滤作用,从白水中回收纤维和填料,并使超清滤液回用,或使浆料浓缩达到要求。 The filter disc 31 rotates to the screen washing area, which is connected to the atmosphere, and the water flow ejected from the nozzle of the swinging spray device regenerates the filter screen, and the filter screen after the recovery of the filtering capacity enters the next filter cycle.
