Arranged on the lower end of pulverizer, the discharge port of suspended hood lower end is located at the surface of horizontal conveyer, and the inlet scoop of suspended hood is passed through
Separator is connected with the inlet scoop of wind turbine, and the air outlet of wind turbine is connected with deduster, and horizontal conveyer is by the feeding after pulverization process
Material is transported to elevator, it is characterised in that the suspended hood uses the structure of square top and round bottom, and upper end area is more than lower face
Product；Aspiration channel is located at the upper end of suspended hood, and the discharge port of pulverizer is provided with the discharge casing stretched into suspended hood；Suspended hood
Sealing sleeve pipe is set with outside discharge duct, sealing sleeve pipe bottom is connected with horizontal conveyer；The bottom of discharge duct is provided with connecting rod and unloads
Bin gate, and connecting rod swing mouth is sealed with lining cloth.
For the utility model using the suspended hood of square top and round bottom shape easy to add discharge casing, discharge casing can facilitate material
Water conservancy diversion, while effectively prevent air-flow from taking away material, block air hose；The sealing sleeve pipe and water installed on the discharge duct of suspended hood lower end
Material envelope is formed between horizontal conveyor, can effectively prevent horizontal conveyer from sucking air, ensures air out of pulverizing chamber by carrying
High air draught efficiency；Connecting rod Dump gate can use electronic, pneumatic or hydraulic-driven form control connecting rod, while be put in connecting rod
Open one's mouth and carry out the sealing effect that sealing further improves suspended hood.Less suction air volume can be utilized to obtain using this structure
Larger air draught speed is obtained, so that then air and material pass through together with the material after crushing again together by pulverizer
Sieve aperture.
Further, the side wall of suspended hood is equipped with transparent viewing port.Easy to observe pulverizer discharging situation, prevent from blocking up
Plug.
Further, the horizontal conveyer is spiral conveyer.
Further, the deduster uses T-BLC Bag self-cleaning formula dedusters.Simple in structure, operating mode is transparent in deduster
Spend, be conveniently replaceable cloth bag, and small, good seal performance.
Further, pressure door pipe is housed in the sealing sleeve pipe.So as to ensure that sealing sleeve pipe increases material envelope by negative pressure
Effect.
The utility model is simple in structure, feed is crushed yield by the improvement to devices such as suspended hood and pulverizers and carries
It is high by more than 70%, and pulverizer free from dust is excessive, runs well in suspended hood, it is substantially high without clogging, drafting efficiency.
