The top of dome valve, the ash cellar is connected with pneumatic transporting ash pipe, and the rear end lower of the outer outlet body is fixed with dust absorption fan, institute
The import for stating dust absorption fan is fixedly connected with ash-sucking cover, and the ash-sucking cover passes through the lower part of outer outlet body face ash cellar, the suction ash
Filter screen is installed, the outlet of the dust absorption fan is connected to by delivery pipe with the bulk cement storage tank being arranged in outside outer outlet body solid in cover
It is fixed, ball valve is installed, the lower part of the bulk cement storage tank is connected by ash releasing tube with pneumatic transporting ash pipe, the row in the delivery pipe
Ash pipe is obliquely installed with pneumatic transporting ash pipe, is equipped with plug valve on the ash releasing tube.
Preferably, exhaust valve, intake valve are installed at the top of the bulk cement storage tank.
Compared with prior art, the beneficial effects of the utility model are: this is practical by the way that dust suction wind is arranged in outer outlet body
The ash that ash cellar lower part is leaked is siphoned away to be transported in bulk cement storage tank and be stored by machine, the high pressure gas meeting of conveying ash in pneumatic transporting ash pipe
Pass through the ash releasing tube being obliquely installed by siphon principle the ash in bulk cement storage tank is absorbed into pneumatic transporting ash pipe, it will be in bulk cement storage tank
Ash is transported in ash cellar, to realize that when such discharge duct discharge leaked raises to dust fugitive dust circulation and stress is revealed in ash cellar
Grey fugitive dust can be absorbed completely, prevented pollution atmosphere, protected surrounding enviroment, and the ash for falling in the lower part Hui Ku does not need artificial treatment,
It ensure that personnel health.

In figure: ash cellar 1, discharge duct 3, dome valve 4, switch gate 5, pneumatic transporting ash pipe 6, dust absorption fan 7, inhales ash at outer outlet body 2
Cover 8, filter screen 9, delivery pipe 10, ball valve 11, bulk cement storage tank 12, exhaust valve 13, intake valve 14, ash releasing tube 15, plug valve 16.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of thermal power plant ash library cleaning device is arranged including ash cellar 1 and its outside
It is used to support the outer outlet body 2 of fixed ash cellar 1, the front end of the outer outlet body 2 is provided with switch gate 5, the bottom setting of the ash cellar 1
There is discharge duct 3, dome valve 4 is installed, the top of the ash cellar 1 is connected with pneumatic transporting ash pipe 6, described on the discharge duct 3
The rear end lower of outer outlet body 2 is fixed with dust absorption fan 7, and the import of the dust absorption fan 7 is fixedly connected with ash-sucking cover 8, the suction
Ash cover 8 passes through the lower part of 2 face ash cellar 1 of outer outlet body, and filter screen 9 is equipped in the ash-sucking cover 8, and the dust absorption fan 7 goes out
Mouth is connected to fixation with the bulk cement storage tank 12 being arranged in outside outer outlet body 2 by delivery pipe 10, is equipped with ball valve in the delivery pipe 10
11, the lower part of the bulk cement storage tank 12 is connected by ash releasing tube 15 with pneumatic transporting ash pipe 6, the ash releasing tube 15 and pneumatic transporting ash pipe
6 are obliquely installed, and are equipped with plug valve 16 on the ash releasing tube 15.
The top of the bulk cement storage tank 12 is equipped with exhaust valve 13, intake valve 14.
Working principle: in use, when automobile fills ash, ash is transported away by switch gate 5 and unloads grey completion by automobile,
