Activated carbon material crushing device

Abstract

The invention provides an activated carbon material crushing device comprising a rack, and a crushing mechanism and a dust removal mechanism which are arranged on the rack. The dust removal mechanismcomprises an L-shaped dust removal box, a first driving motor and a second driving motor which are connected with the rack; the end, in the vertical direction, of the dust removal box is connected with a discharging port, and a first rotating shaft is arranged at the position, located below the discharging port, in the dust removal box, and provided with a scraper; the end, in the horizontal direction, of the dust removal box is provided with an exhaust fan, and an arc-shaped filter screen is arranged at the position, located between the rotating shaft and the exhaust fan, of the dust removalbox; the end, located on the exhaust fan, in the dust removal box is provided with a filter layer; activated carbon materials are crushed by the crushing mechanism, and then enter the dust removal box; the exhaust fan in the dust removal box is used for exhaust, so that fine carbon particles are pumped out, and absorbed on the filter layer; activated carbon particles in the dust removal box are stirred through the scraper on the rotating shaft, and holes in the arc-shaped filter screen are prevented from being blocked by large activated carbon particles; and meanwhile filtered activated carbonis pushed out of the dust removal box.

Description

Problems solved by technology

[0002] Activated carbon is amorphous carbon obtained through processing. It has a large specific surface area and has good adsorption capacity for gases, inorganic or organic substances in solution and colloidal particles. It has stable chemical properties, high mechanical strength, acid resistance, Alkali-resistant, heat-resistant, insoluble in water and organic solvents, can be recycled, has been widely used in chemical industry, environmental protection, food processing, metallurgy, chemical protection and other fields; the main raw materials of activated carbon are wood, fruit shell, coconut shell, Walnut shells, apricot shells and other carbon-rich organic materials, put these carbon-containing raw materials into the activation furnace, and convert them into activated carbon through pyrolysis under high temperature and certain pressure. Pulverize them into the size required for production; most of the existing pulverizers use the high-speed rotation of the crushing knife to pulverize the activated carbon raw materials. This kind of pulverizer will pulverize a small amount of activated carbon raw materials into carbon powder-like fine particles. These carbon powder particles It cannot be decomposed and excreted in the human body. If it is inhaled for a long time or if it is inhaled a lot at one time, it will easily cause respiratory diseases, cause lung diseases, and in severe cases, it can cause cancer, which seriously affects the health of the staff in the production workshop; and when the toner particles in the workshop If it reaches a certain concentration, dust explosion will easily occur when encountering an open flame or sparks, and then a fire will occur, which will bring great hidden dangers to the production safety of the factory.
