Abstract

The invention relates to the technical field of chemical equipment, particularly to a liquid filtering device. The device comprises a tank, wherein a feeding port and a discharging port are arranged on the tank; a magnetic filtering net, a filtering cloth, a decolorizing filtering medium and a micro-porous filtering medium are installed in the tank sequentially from top to bottom; and a receiver is connected to an outlet of the tank. With the adoption of the technical scheme, the liquid filtering device has the benefits as follows: the liquid filtering device is good in filtering effect and capable of effectively removing tiny impurities in a liquid and removing pigments in the liquid; reduced-pressure suction filtration is adopted, the suction filtration speed is high, and the efficiency is high; and a manhole is arranged on the tank, so that maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a liquid filtering device. Background technique [0002] Filtration is to force the fluid in the liquid-solid or gas-solid mixture to pass through the porous filter medium, and to intercept the suspended solid particles in it, so as to realize the separation of the mixture. It is a unit operation belonging to the fluid dynamic process. [0003] Filtration is an important process in industrial production, such as oil filtration in petrochemical industry, filtration and purification of dyestuffs, sewage treatment in chemical production, filtration of wine in wine making industry, etc. In order to remove impurities, a layer of mesh or microporous filter media is often placed at the inlet, but this kind of filtration is not thorough, and only large particles of impurities can be removed, some fine particles remain in the liquid, and the filter The speed is slow, the filte...
