-5C（Φ240-Φ120）型盘式真空过滤机技术参数
Technical Parameters of Laboratory Disk Vacuum Filters
盘式真空过滤机用于地质、冶金、煤炭、建材、矿山等科研实验单位在开展矿物可选性实验工作中，作为浮选、重选、磁选等作业后脱水，检测样品时固液分离。机器主要由真空泵、分水滤气器、真空负压罐及两个过滤盘组或其排水通过自控装置自动排水，达到固液分离目的。本产品由原地矿部唯一指定企业生产，执行行业标准。
Disk Vacuum Filter is applicable to geological, metallurgical, building material, mining and other industries for mineral dewatering after flotation, gravity concentration, magnetic separation and other operations in tests on mineral separability and separation of solid -liquid in sample testing. It mainly comprises vacuum pump, moisture air filter,vacuum negative pressure tank and two filter trays with automatic drainage device to be provided to separate solids from liquids. The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

结构简介
Structure
1、结构：DL-5C型过滤机，设有两个容量不同的滤盘，不同量的矿浆可以直接倾入相应容量的盘内进行脱水处理。真空系统主要由旋片式真空泵、分水滤气器、真空负压罐、电磁阀以及真空管道组成。
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.
电控系统由控制面板及继电器等元件组成其结构原理见下图：
The electric control system is composed of control panel, relay, and other components. See the figure for its structure.

2、过滤原理：真空泵起动后约10秒内，可将真空负压罐内，抽成一个不小于91.2kpa(684毫米汞柱)的负压腔，然后接通电磁阀3或5在压力差的作用下，使滤盘内的液体很快透过滤纸，达到脱水的目的。
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、结构特点：
3. Structural Feature:
本机结构简单、紧凑，真空系统工作可靠，具有较高的真空度，为防止真空负压罐内的液体进入真空泵，在器内设置了上下接点，当液体达到预定高度时真空泵自动停车，同时打开放气电磁阀，待液体排完后自行起动。
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.
