DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0020] A dust unloading device for an ash silo, wherein a discharger 2 is connected to the discharge port of the ash silo 12, and the specifications of the discharger 2 are selected according to the process requirements. The discharger 2 comprises a three-way mixing tube 4, and the discharge end of the mixing tube 4 is connected to a suction and exhaust vehicle. The end of the mixing tube 4 away from the suction and exhaust vehicle is connected to an air intake pipe 13, and compressed gas enters the air intake pipe 13. The compressed gas can be compressed air or compressed nitrogen. A connecting pipe is provided between the top end of the mixing tube 4 and the discharge port of the discharger 2, and a pressurizing mechanism connected to the air intake pipe 13 is provided on the side wall of the ash silo 12. The mixing tube 4 can mix the dust with the compressed gas, and utilize the pressure difference to discharge the ash-gas mixture from the outlet to the suction and exhaust vehicle, so that the ash unloading becomes smoother.

[0021] Furthermore, an ash discharge ball valve 1 is provided between the ash bin and the discharger 2, which can cut off the passage between the ash bin 12 and the discharger 2 to prevent dust from falling.

[0022] Furthermore, the connecting pipe is a reducing pipe 3 .

[0023] Furthermore, a pipe support 11 is provided at the bottom of the air intake pipe 13 and the mixing pipe 4 to ensure the stability of the air intake pipe 13 and the mixing pipe 4.

[0024] Furthermore, a first ball valve 6 is provided on the air inlet pipe 13 to stop the air supply when dust unloading is not required or the equipment needs to be repaired.

[0025] Furthermore, a pressure reducing valve 5 is provided on the air inlet pipe 13 and between the first ball valve 6 and the mixing pipe 4 , and the outlet pressure of the pressure reducing valve 5 can be adjusted according to process requirements.
