Abstract

The invention discloses a dust separating and gas drying and circulating system and a dust separating and gas drying and circulating method of an industrial ball grinding mill. The dust separating and gas drying and circulating system comprises a gas outlet pipeline, a ball grinding roller, a gas inlet pipeline, a feed inlet, an activated carbon drying and adsorbing pipe, a cyclone separator and a gas circulating pump; during an ore grinding process, dust in the ball grinding roller is pumped out by the gas circulating pump and enters the cyclone separator so as to carry out gas-dust particle separation, separated gas enters the activated carbon drying and adsorbing pipe again so as to carry out secondary adsorption on water and fine particles in the gas, and the clean dried gas finally enters the ball grinding mill for being recycled; the dust particles enters the ball grinding roller from the feed inlet so as to carry out ore grinding again. According to the dust separating and gas drying and circulating system disclosed by the invention, separation of gas and dust in the ball grinding roller is realized, the gas is recycled, the dust is reground, and no any pollution and no any influence are generated on external environment.

Description

A kind of industrial ball mill dust separation and gas dry cycle system and method
Technical field
The present invention relates to a kind of dust separation and gas dry cycle system and method, specifically one can realizeThe green circulatory utilization of grinding machine internal gas in grinding process, avoid the industrial ball mill dust of environment to external world to divideFrom and gas dry cycle system and method.
Background technology
In laboratory or industry, dry ball can cause a large amount of dust pollutions at running chats at present,And existing industry is only that air is carried out simply separating to realize the cleaning of gas, but that this is difficult to adapt to is on-the-spot complicatedRequirement, so carry out green circular treatment by the dust pollution in grinding machine,, to external world's discharge, has not realized good workAn on-the-spot problem anxious to be resolved as environment.
Summary of the invention
The object of the invention is for problems of the prior art, provide a kind of simple in structure, can realize and not polluteThe industrial ball mill dust separation of environment and gas dry cycle system and method.
For achieving the above object, the technical scheme that the present invention deals with problems is: comprise ball milling cylinder, cyclone separator, gasBody circulating pump; The outlet pipe of described ball milling cylinder is connected with the entrance of cyclone separator, between feed channel and cyclone separatorBe provided with gas circulator, the upper gas outlet of described cyclone separator is connected with the dry adsorption tube of active carbon by the road, and active carbon is dryThe gas outlet of adsorption tube is connected with the admission line of ball milling cylinder by the road, the lower discharge port of cyclone separator by the road with ballThe charging aperture of mill cylinder is connected.
Described admission line is located at the top of ball milling cylinder one end, and charging aperture is located at the bottom of admission line.
The industrial ball mill dust separation of said system and a gas dry cycle method, in grinding process: gasCirculating pump enters cyclone separator by the dust extraction in ball milling cylinder and carries out fuel gas and dust particle separation, and isolated gas entersAfter entering the dry adsorption tube of active carbon the moisture in gas, fines being adsorbed, the gas of clean dried enters ball milling againIn machine, recycle; And dust granules enters in ball milling cylinder from charging aperture and carries out ore grinding again, realize gas in ball milling cylinderDust separation, gas circulation utilization, dust is regrinded, can be on outside environment and impact.
Beneficial effect: owing to having adopted technique scheme, the present invention by gas circulator by the dust gas in grinding machineBody is derived, and passes through respectively preliminary cyclonic separation, then it is dry to carry out charcoal absorption, gas circulation utilization, and dust granules is regrinded,Whole system has realized periodic duty. Compared with directly discharging with existing waste gas, both avoid dust pollution, realized returning of powderReceive recycling, provide useful approach to industrial milling system dust anti-flaming, explosion-proof again. It is simple in structure, environmental protection, toolThere is practicality widely.
