The specific embodiment
Refer to Fig. 1-Fig. 8, the fire coal that the utility model provides is pulverized conveyer and is comprised dog-house 101, grinding chamber 201, wind chamber 301 and conveyance conduit 401.Dog-house 101 bottoms are fixed on a side of grinding chamber 201, and communicate with the inside of grinding chamber 201; Grinding chamber 201 is pulverized mill 204 and two groups of grinding mills 206 with one group, pulverize mill 204 and be provided with six solid T-shaped crushed pieces 205, grind mill 206 and be provided with six leg-of-mutton abrasive articles 207, abrasive article 207, with leg-of-mutton through hole 208, is pulverized mill 204 near the bottom of dog-house 101; Wind chamber 301 is fixed and communicates with grinding chamber 201, and wind chamber 301 inside are provided with axial flow blower 302; Conveyance conduit 401 is fixed and communicates with wind chamber 301.
While using this fire coal to pulverize conveyer; by dog-house 101, fire coal is dropped into grinding chamber 201; first by solid crushed piece 205, the burning coal powder of bulk is broken into smaller piece; then by hollow abrasive article 207, the fire coal of fritter is ground to form to less particle or powder; finally by the axial flow blower 302 of wind chamber 301, extracted out grinding chamber 201, by conveyance conduit 401, sent.Conveyance conduit 401 can connect combustion apparatus, also can connect storage facilities.The fire coal of processing like this has the incendive feature of appearance, substantially there will not be unburnt phenomenon, therefore also can not discharge the toxic gases such as carbon monoxide.Select one group of pulverizing mill 204 and two groups of grinding mills 206 to consider for economic and practical angle, guarantee to complete fast and effectively grinding work, also guaranteed that the cost of whole equipment maintains rational level.
Each group pulverizing mill 204 is provided with six pulverizing mills 204, and each group is ground mill 206 and is provided with six abrasive articles 207, and the edge of mill 206 or pulverizing mill 204 is ground in symmetrical being distributed in.Such design can be pulverized fire coal and grind fast.Solid T-shaped crushed piece 205 can be stronger the fire coal by bulk smash, hollow triangle abrasive article 207 can become less particle or powder by the fire coal of fritter efficiently.
At the sidewall of dog-house 101, be provided with auxiliary air inlet 102, auxiliary air inlet 102 is provided with knob 103 that can regulating air volume.Because wind chamber 301 pumps to conveyance conduit 401 by air, therefore must there is larger air-flow to flow into from dog-house 101, but because dog-house 101 is main, be responsible for delivering coal cinder, therefore an auxiliary air inlet 102 need to be set at the sidewall of dog-house 101 increases air quantity.Increase a knob 103 simultaneously, can regulate according to actual conditions the size of air quantity.
Grinding chamber 201 is hollow cylinder, its cross section be inwall with the annulus of triangular hill 202, projection 202 has 72.Leg-of-mutton protruding 202 can allow grinding chamber 201 firmer on the one hand, on the other hand, compare smooth inwall, and the projection effective assisted milling part 207 of 202 energy and crushed piece 205 make fire coal pulverize and grind.
Grinding chamber 201 inside are provided with axle 203, and axle 203 extends to wind chamber 301, pulverize mill 204 and grind mill 206 to be fixed in axle 203.Wind chamber 301 is cylinder, and axial flow blower 302 is fixed in axle 203.Axial flow blower 302, pulverizing mill 204 and grinding mill 206 are fixed in same axle 203, can save space and save electric weight.
This fire coal is pulverized conveyer and is also comprised casing 501, and this casing 501 is sheathed on the outside of grinding chamber 201 and wind chamber 301, and casing 501 inside are provided with the support 502 that supports grinding chamber 201; The delivery outlet of the entrance of dog-house 101 and conveyance conduit 401 is positioned at the outside of casing 501.Casing 501 can make whole equipment more stable, also can play certain protective effect simultaneously, has also facilitated conveyance and transportation.
Crushed piece 205, abrasive article 207 and projection 202 use carbide alloy are made.The parts that adopt carbide alloy to make are more durable, also increased the service life of whole equipment when increasing efficiency.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
