Description

A kind of coal-grinding apparatus for efficient hot water boiler
Technical field
The present invention relates to heat power plant boiler coal-grinding apparatus, particularly relate to a kind of coal-grinding apparatus for efficient hot water boiler.
Background technology
Coal pulverizer is by coal crusher the machinery wearing into coal dust, and it is the important auxiliary equipment of coal-powder boiler. 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, smashing and grind three kinds of modes and carry out. The energy wherein crushing process consumption is economized most. Grinding process takes energy most. Various coal pulverizers all have two or three above-mentioned mode concurrently in pulverizing process, but with which kind of for main then depending on the type of coal pulverizer.
Coal pulverizer in the market is primarily present the problems such as coal-grinding is inefficient, equipment volume is relatively big, power consumption is more, coal-grinding fineness is poor.
Summary of the invention
It is an object of the invention 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 the present invention 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, rotating shaft, multiple hitting roller, described electric rotating machinery apparatus is on preliminary broken coal case end face, connecting the rotating shaft within preliminary broken coal case, the plurality of hitting roller device is in the rotating 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, and device drive motor on described fine coal-grinding case right flank 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 crush box inwall is for thickening rustless steel inwall.
Beneficial effects of the present invention: a kind of coal-grinding apparatus for efficient hot water boiler of the present invention, coal-grinding efficiency is higher, equipment volume is less, power consumption is less, coal-grinding fineness is better; The present invention 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.
