And the pneumatic conveying system is used for conveying the calcium carbide dust collected by the dust removal system to the calcium carbide bin 8. And calcium carbide dust in the calcium carbide bin 8 is used by the generation system. The utility model provides a carbide dust recovery system can collect the dust that produces when unloading the carbide to improve the environment in carbide storehouse, reduced the consumption of carbide.
Further, the dust removal system includes a dust remover 2, a compressed air delivery device, and a fan. The dust collector 2 includes a housing and a dust filter bag. One side of the shell is provided with an air inlet, and the other side is provided with an air outlet. The dust filtering bag is positioned in the shell. A dust collecting chamber is arranged below the dust filtering bag. The dust collection chamber is provided with an opening and closing valve. The air outlet of the shell is communicated with a fan. The compressed air device 3 is communicated with the housing, and a communication port of the compressed air device 3 and the housing is arranged at the upper part of the housing. The compressed air equipment 3 is used for conveying compressed air into the shell so as to strip the calcium carbide dust on the dust filter bag. The compressed air apparatus 3 includes: the compressed air self-buffering tank, the air storage tank, the self-operated pressure reducing valve, the dehydrator, the compressed air distributor, the oil atomizer and the like.
Calcium carbide dust generated during calcium carbide unloading enters the shell from the air inlet of the shell under the suction action of the fan. Heavier particles in the calcium carbide dust fall into a dust collection chamber below under the action of self gravity. The carbide dust will then flow upward through the dust filter bag. In the process, fine particles in the calcium carbide dust can be adsorbed on the dust filter bag. The calcium carbide dust on the dust filter bag is accumulated continuously. The dust remover is automatically controlled by a PLC control system, and dust discharge of the dust filter bag is periodically and circularly controlled by a PLC program. When the ash discharge set time value is reached, the PLC control system closes the air inlet of the dust remover 2 and controls the compressed air equipment 3 to convey compressed air into the shell of the dust remover 2. The compressed air rapidly expands over the housing for a very short period of time and then floods the dust filter bag, causing it to expand and deform and vibrate. The calcium carbide dust attached to the outer surface of the dust filter bag is peeled off and falls into the dust collection chamber. In order to ensure continuous dust removal of the dust removal system, a plurality of dust removal chambers may be provided within the housing of the dust remover 2. The compressed air equipment 3 sequentially peels off the calcium carbide dust on the dust filtering bags in the dust removing chambers.

And discharging the filtered air in the carbide storehouse out of the carbide storehouse along a chimney under the action of a fan.
In one embodiment of the present invention, the pneumatic conveying system comprises a bin pump 5 and a nitrogen conveying device 6. The bin pump 5 is used for communicating the dust collection chamber with the calcium carbide bin 8. The nitrogen gas delivery device 6 is used for delivering nitrogen gas to the bin pump 5. The nitrogen blows the calcium carbide dust in the bin pump 5 into the calcium carbide bin 8. After the on-off valve of the dust collection chamber is opened, the calcium carbide dust in the dust collection chamber enters the bin pump 5. When the amount of the calcium carbide dust in the bin pump 5 reaches a certain amount, the nitrogen conveying equipment 6 blows nitrogen into the bin pump 5, so that the calcium carbide dust in the bin pump 5 flows into the calcium carbide bin 8.
Further, a weigher is provided in the hopper pump 5. A nitrogen valve is arranged on a nitrogen pipeline of the nitrogen conveying device 6. When the weigher senses that the amount of the calcium carbide dust in the bin pump 5 reaches the set value, the nitrogen valve is opened, and the nitrogen conveying equipment 6 conveys nitrogen to the bin pump 5.
Further, a screw conveyor 4 is provided between the dust collecting chamber and the hopper pump 5. The screw conveyor 4 is used for conveying the calcium carbide dust in the dust collecting chamber to the bin pump 5.

The dust cover 1 is connected with the dust removing system through a dust removing pipeline. The calcium carbide dust in the dust cover 1 enters the dust remover 2 through the dust removing pipeline. In particular, the dust excluding hood is angular in cross section and arranged in a 7 shape. So set up, not only can reach the purpose of gathering dust, can also avoid simultaneously unloading the carbide and cause the interference.
In conclusion, the recovery process of the calcium carbide dust is as follows: the calcium carbide dust gathers under the dust cover 1. Under the action of the explosion-proof fan 7, the calcium carbide dust below the dust cover 1 enters the shell of the dust remover 2 through the dust removal pipeline. Then, heavier particles in the calcium carbide dust can directly fall into the dust collection chamber. The carbide dust then moves upward through the dust filter bag. Fine particles in the calcium carbide dust can be adsorbed on the dust filter bag. And then discharging the filtered calcium carbide dust out of the calcium carbide storehouse through a chimney. After the dust remover runs for a set time value, the PLC control system controls the air inlet of the dust remover 2 to be closed and controls the compressed air equipment 3 to convey compressed air into the shell of the dust remover 2 so as to expand the dust filter bag and generate vibration. The calcium carbide dust attached to the dust filter bag is peeled off and falls into the dust collection chamber. When the calcium carbide dust in the dust collection chamber reaches a certain amount, the opening and closing valve of the dust collection chamber is opened, and the calcium carbide dust is conveyed into the bin pump 5 under the action of the screw conveyor 4. When the weigher induces that the calcium carbide dust in the bin pump 5 reaches a set value, the nitrogen valve is opened. And the nitrogen conveying equipment 6 conveys nitrogen into the bin pump 5, and the nitrogen blows calcium carbide dust in the bin pump 5 into the calcium carbide bin 8.
