結構簡介
Structure
1、結構:DL-5C型過濾機,設有兩個容量不同的濾盤,不同量的礦漿可以直接傾入相應容量的盤內進行脫水處理。真空系統主要由旋片式真空泵、分水濾氣器、真空負壓罐、電磁閥以及真空管道組成。
1. Structure: DL-5C filter has two filter disks with different capacities. Slurry of different amount can be directly fed into the disk with corresponding capacity for dewatering. The vacuum system is mainly composed of rotary-vane vacuum pump, water-separating gas filter, vacuum negative pressure jar, electromagnetic valve, and vacuum duct.
電控系統由控制面板及繼電器等元件組成其結構原理見下圖:
The electric control system is composed of control panel, relay, and other components. See the figure for its structure.
(1)Φ
(1) filter disk with the diameter of 120mm; (2) filter disk with the diameter of 240mm; (3, 5, 7, 9) electromagnetic valve; (4) vacuum meter; (6) hydraulic control assembly and vacuum negative pressure jar; (8) automatic drain valve; (9) water-separating gas filter; (10) vacuum pump; (11) motor
2、過濾原理:真空泵起動后約10秒內,可將真空負壓罐內,抽成一個不小于91.2kpa(684毫米汞柱)的負壓腔,然后接通電磁閥3或5在壓力差的作用下,使濾盤內的液體很快透過濾紙,達到脫水的目的。
2. Working Principle: Within around 10s after the vacuum pump is started, make a vacuum capacity with the pressure of not lower than 91.2kpa (684mm mercury column) in the vacuum negative pressure jar. Then connect the electromagnetic valves 3 and 5. Under the action of pressure difference, the liquid in the filter disk permeates into the filter paper very quickly so that the purpose of dewatering can be served.
3、結構特點:
3. Structural Feature:
本機結構簡單、緊湊,真空系統工作可靠,具有較高的真空度,為防止真空負壓罐內的液體進入真空泵,在器內設置了上下接點,當液體達到預定高度時真空泵自動停車,同時打開放氣電磁閥,待液體排完后自行起動。
This machine features simple and compact structure, reliable operation of vacuum system, and high vacuum degree.
To prevent the liquid in the vacuum negative pressure jar from entering the vacuum pump, upper and lower connection points are designed for this machine. When the liquid reached the preset height, the vacuum pump stops working automatically. At the same time, open the air-release valve. It starts up automatically after all the liquid is discharged.
