Dust-free pulverizing device for activated carbon

Abstract

The invention relates to a dust-free pulverizing device for activated carbon. A feed screw conveyor is arranged at a feed inlet of a raymond machine, a discharge outlet of the raymond machine is sequentially connected with a cyclone separator, a pulse bag-type dust collector and a centrifugal fan through a negative-pressure pipeline; each of material dropping ports of the bottom ends of the cyclone separator and the pulse bag-type dust collector is provided with an airlock; the lower part of the cyclone separator is provided with a finished product bin, and the airlock is connected with the finished product bin; the airlock of the pulse bag-type dust collector is connected with a finished product screw conveyor, and the discharge end of the finished product screw conveyor is connected with the finished product bin; an air outlet of the centrifugal fan is connected to a spray tower through a dust outlet pipeline; the bottom of the spray tower is provided with a liquid collecting port, and the top of the spray tower is provided with a gas outlet; the liquid collecting port is connected with a recycling pool through a water outlet pipeline. The device is simple and reasonable in structure, and a production method is convenient to implement; the device greatly reduces the dust pollution of activated carbon in the pulverizing process, thereby providing a good working environment for workers; and the device can collect active carbon in dust, thereby avoiding wasting.

Description

technical field [0001] The invention relates to the technical field of activated carbon production, in particular to an activated carbon dust-free grinding device. Background technique [0002] Activated carbon is powdery or granular amorphous carbon, its structure is irregular because microcrystalline carbon has fine pores between cross-links, and carbon tissue defects will be generated during activation, so it has highly developed pores Structure and huge specific surface area, strong adsorption capacity, good chemical stability, high mechanical strength, and easy regeneration after use failure. Activated carbon processed by mill is widely used in chemical industry, food processing, medical and health, agriculture, national defense and other fields. [0003] The commonly used mills for grinding activated carbon are ball mill and Raymond mill. The shaped ball mill is continuously fed and discharged. Generally, the feed amount is adjusted according to the particle size of ...

AI Technical Summary

Problems solved by technology

However, during the grinding process of the ray mill, due to its light specific gravity, a large amount of dust will be emitted during the production process, which seriously affects the health of the production workers and the environmental quality of the surrounding areas.
