[0006] By adopting the above technical scheme, the bin pump of the dry dust removal is replaced from the original tank type bin pump to the bend pipe type, the blast furnace dust directly enters the ash conveying pipe through the bend pipe, so that there is no blast furnace dust accumulation in the bend pipe, the probability of blockage is reduced, the steam source continuously provides steam, the steam pipe is used for heat tracing, the temperature inside the bend pipe is effectively guaranteed, the moisture content in the blast furnace dust is reduced, and the possibility of the blast furnace dust condensing into blocks is reduced.

[0007] Optionally, one end of the bend pipe close to the bin body ball valve is provided with an upper flange for connecting with the bin body ball valve, and the specification of the upper flange is DN200.

[0008] By adopting the above technical scheme, the setting of the upper flange can effectively improve the connection efficiency of the novel dry dust removal bin pump of the application and the bin body ball valve, shorten the assembly time, and has high convenience and practicality.

[0009] Optionally, the size of the bend pipe is DN125.

[0011] Optionally, a reducing pipe is provided between the bend and the upper flange, wherein the end of the reducing pipe connected to the upper flange has a diameter of DN200, and the end connected to the bend has a diameter of DN125.

Since the size of the steam pipe is small, the probability of blockage inside the bend can be effectively reduced.

[0017] Optionally, the side wall of the bend is connected to a quick connector, which is used to connect to the nitrogen blowing pipe of the original chamber pump.

[0018] By adopting the above technical solution and setting up a quick connector, it is possible to quickly connect with the nitrogen-assisted blowing pipe of the original dust collection pump, thereby shortening the assembly time of the novel dry dust collection pump of this application, effectively improving the assembly efficiency, and having high convenience and practicality, while ensuring sufficient ash conveying pressure in the bend.

[0019] Optionally, the outer wall of the bend is fitted with thermal insulation cotton.
