Background technology
At present, along with the significantly lifting of coal resources price, also thereupon well sold and in short supply as the coal slime of coal industry deep processing byproduct, but because moisture of coal fines is high, viscosity is large, calorific value is on the low side, output is large, must could use after drying.Therefore, the domestic system that has occurred a lot of relevant coal slimes oven dry, can reduce the original moisture of coal slime, makes full use of this resource, turns waste into wealth.In coal slime drying system, coal slime feed arrangement is a vitals to whole system; it directly affects the ruuning situation of whole system; because moisture of coal fines high viscosity is large, particle is thin; occluding device very easily in course of conveying; if charging is not smooth; occur that putty stuck phenomenon can cause the shutdown maintenance of whole system, tight mistake is produced, and causes heavy losses.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of coal slime propeller is provided, and when it can be realized coal slime and enters combustion furnace as fuel, carries to fast and simple and steady and continuous.
For achieving the above object, the utility model adopts following technical proposals:
Coal slime propeller, comprise outer cylinder body and be arranged at the upper left charging aperture of outer cylinder body and the discharging opening that is arranged at right-hand member, propeller is made up of main shaft and the stranded rotating vane that is connected to main shaft outer rim, main shaft right-hand member is provided with coal slime breaking device, propeller left end connects correction system and dynamical system in turn, there is coal slime purge passage at outer cylinder body peripheral hardware, coal slime purge passage is provided with coal slime and purges water inlet and coal slime purging wind entrance, coal slime purge passage is provided with cooling jacket cylinder outward, cooling water sleeve is provided with cooling water inlet and coolant outlet, described cooling water sleeve outside is provided with air distribution sleeve pipe, air distribution sleeve pipe is provided with coal slime air distribution entrance, establish row's coal slime purge hole in outer cylinder body radial direction.
Described coal slime breaking device is monolithic or multi-disc.
Described coal slime breaking device is dentation or strip.
Described main shaft and horizontal line angle are 0 °～75 °, and coal slime propeller and horizontal line angle are 0 °～75 °, by the Action of Gravity Field of coal slime self, more laborsaving when so downward propelling coal slime.
The utility model provides power by dynamical system, realize and adjust the speed of mainshaft and concentricity by correction system, coal slime enters propeller by charging aperture, under the rotation of main shaft and rotating vane promotes, enter in burner hearth and burn, coal slime near burner hearth place is difficult for being scattered because high-temperature baking easily lumps to stick on furnace wall, rotate and realize fragmentation with main shaft by coal slime breaking device, and purge by coal slime air that wind entrance enters and dispel and enter burner hearth, for reducing the temperature of the angle of rake outer cylinder body of coal slime, be unlikely to that coal slime is dry to be bonded on barrel, in outer cylinder body additional, there is cooling water sleeve, cooling water leads to spiral by cooling water inlet and enters cavity near outlet side, after cooling water heat exchange, flowed out by coolant outlet, extend coal slime angle of rake service life, there is coal slime clogging in order to process at running, set up coal slime purge passage, open row's coal slime purge hole in outer cylinder body radial direction, at ordinary times by coal slime purge wind entrance pass into air keep aperture unobstructed, if there is clogging, close coal slime and purge wind entrance, passing into water under high pressure at coal slime purging water inlet dredges, after handling, switching to purging wind keeps aperture unobstructed again.
The beneficial effects of the utility model are,
1. be provided with cooling water sleeve, cooling water leads to spiral by cooling water inlet and enters cavity near outlet side, after cooling water heat exchange, is flowed out by coolant outlet, has extended coal slime angle of rake service life;
2. open row's coal slime purge hole in outer cylinder body radial direction, at ordinary times by coal slime purge wind entrance pass into air keep aperture unobstructed, if there is clogging, close coal slime and purge wind entrance, pass into water under high pressure at coal slime purging water inlet and dredge, after handling, then it is unobstructed to switch to purging wind maintenance aperture, wind and water cooperatively interact like this, can effectively solve blockage problem;
3. in the utility model, coal slime breaking device, cooling water, water under high pressure, sweep wind and cooperatively interact, can realize coal slime and enter combustion furnace as fuel time, carry to fast and simple and steady and continuous.
