Description

Technical Field

[0001] The utility model relates to the technical field of dust dispersing devices, in particular to a compressed air dust dispersing device. Background Art

[0002] Circulating fluidized bed boilers produce a lot of coal ash when in use, and the coal ash is stored in ash silos. The existing ash silos have been in operation for a long time, and the bottom is now hardened, which makes it easy to get clogged when discharging ash, making it difficult to discharge ash. There are no professional operating tools for unblocking the pipeline, which leads to low efficiency of the staff, slow unblocking speed, and high labor intensity.

[0003] Therefore, those skilled in the art are in urgent need of developing a compressed air dust removal device. Utility Model Content

[0006] Preferably, the driving assembly includes a driving box, a driving rod is provided inside the driving box, one end of the driving rod extends into the ash bin and contacts with the toggle rod, the driving rod and the ash bin are slidingly and sealingly connected, a support plate is provided on the driving rod, the support plate and the driving rod are slidingly connected, the end of the driving rod away from the ash bin is connected to a push plate, the support plate and the driving box are fixedly connected, and the push plate and the driving box are slidingly connected.

[0007] Preferably, a cam is provided at one end of the push plate away from the driving rod, a motor is connected to the outside of the driving box, an output end of the motor extends into the driving box and is connected to the cam, and a spring is provided between the support plate and the push plate.

[0008] Preferably, the lower end of the toggle rod extends to the interior of the ash placing pipe.

[0009] Preferably, a gate valve is provided below the ash discharge pipe, and a check valve and a ball valve are provided in sequence at the bottom of the compressed air pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the utility model, when ash discharge is difficult, the staff increases the pressure inside the compressed air pipe, thereby reversing the air at the bottom of the ash bin, thereby achieving the effect of unblocking the ash discharge pipe, and the operation is convenient and efficient; at the same time, the cam is driven to rotate by the motor, so that the cam drives the push plate to move left and compresses the spring, and the left end of the push plate is connected to the drive rod, which in turn drives the drive rod to move left. When the cam is separated from the push plate, the spring releases the elastic force and drives the push plate to move right, and then the drive rod moves right, thereby realizing the left and right reciprocating motion of the drive rod, and the left and right motion of the drive rod drives the toggle rod to rotate up and down, thereby achieving the unblocking of the ash bin, reducing the blockage of the ash discharge pipe, and thus improving the ash discharge efficiency.
