Description
Technical field
This utility model relates to heat power plant boiler coal-grinding apparatus, particularly relates to a kind of coal-grinding apparatus for efficient hot water boiler.
Background technology
Coal pulverizer is that it is the important auxiliary equipment of coal-powder boiler by coal crusher the machinery of wearing into coal dust.Coal-grinding process is that coal is broken and the ever-increasing process of surface area.Increase new surface area, it is necessary to overcome the adhesion between molecular solids, thus need consumed energy.
Coal is milled into coal dust in coal pulverizer, mainly by crushing, smash and grind three kinds of modes and carry out.Wherein the energy of crushing process consumption saves most.Grinding process most takes energy.Various coal pulverizers all have two or three above-mentioned mode in pulverizing process concurrently, but which kind of is main then depending on the type of coal pulverizer with.
Coal pulverizer in the market is primarily present that coal-grinding is inefficient, equipment volume is compared with the problem such as big, power consumption is more, coal-grinding fineness is poor.
Utility model content
The purpose of this utility model is to provide a kind of coal-grinding apparatus for efficient hot water boiler, can effectively solve deficiency of the prior art, it is provided that a kind of coal-grinding efficiency is higher, equipment volume is less, power consumption is less, coal-grinding fineness is preferably for the coal-grinding apparatus of efficient hot water boiler.
The purpose of this utility model is achieved through the following technical solutions:
A kind of coal-grinding apparatus for efficient hot water boiler, including preliminary broken coal case, fine coal-grinding case, coal chute, coal feeding pipe, goes out coal bunker, and described preliminary broken coal bottom end passes through coal chute device on fine coal-grinding case top；Described preliminary broken coal case top device coal feeding pipe；Described fine coal-grinding bottom end device goes out coal bunker；Two rotary striking devices about described preliminary broken coal case interior arrangement, described rotary striking device is made up of electric rotating machine, rotary shaft, multiple hitting roller, described electric rotating machinery apparatus is on preliminary broken coal case end face, connecting the rotary shaft within preliminary broken coal case, the plurality of hitting roller device is in the rotary shaft left and right sides；Described fine coal-grinding case interior arrangement two rows cylinder powdered coal equipment, described often row cylinder powdered coal equipment is made up of the circular rolling wheel in two, left and right, described fine coal-grinding case right flank fills centrally-mounted driving, connects fine coal-grinding case internal cylinder powdered coal equipment；Setup Controller on described fine coal-grinding case left surface, described controller connects cylinder powdered coal equipment, rotary striking device.
Described coal chute interior arrangement electric control valve, described electric control valve connects controller.
Described preliminary broken coal chamber interior wall is for thickening rustless steel inwall.
The beneficial effects of the utility model: a kind of coal-grinding apparatus for efficient hot water boiler of the present utility model, coal-grinding efficiency is higher, equipment volume is less, power consumption is less, coal-grinding fineness is preferable；This utility model is made up of preliminary broken coal case, fine coal-grinding case, two rotary striking devices about described preliminary broken coal case interior arrangement, coal is tentatively pulverized by the mode first passing through impact shock, then preliminary broken coal enters in fine coal-grinding case, rolling fine grinding through fine coal-grinding case interior arrangement two rows cylinder powdered coal equipment, the fineness of pulverized coal obtained is good.
