Technical Field

[0001] The utility model relates to the technical field of coal bunker anti-blocking, in particular to a coal bunker anti-blocking air cannon. Background Art

[0002] The raw coal bunker is an important equipment of the power generation device in the power plant. It mainly plays the effect of combustion power generation in the power generation process to ensure the effect of stable power generation. In the process of providing detection, maintenance and system management services for the power plant, our company found that the raw coal bunker is prone to blockage during feeding, which affects the power generation efficiency of the raw coal bunker and increases the difficulty of maintenance. Therefore, it is necessary to use air cannons to prevent blockage. After searching: An air cannon control system for preventing coal bunker blockage with announcement number CN209209536U includes a coal bunker, and multiple air cannons are arranged on the inner wall of the coal bunker. The air cannons are evenly arranged around the coal bunker. Multiple monitoring devices are arranged on the inner wall of the coal bunker. The monitoring devices are used to observe the blockage position in the coal bunker. The monitoring devices and air cannons are electrically connected to the operation controller. The operation controller is used to operate the air cannon according to the monitoring results of the monitoring device.

[0003] However, the above-mentioned coal bunker anti-blocking air cannon still has some shortcomings. The air cannon installed around the outer side of the coal bunker is not conducive to disassembly and assembly, which is not conducive to the later inspection and maintenance of the air cannon. The air cannon is used to clear the blockage, but it is inconvenient to extend the anti-blocking cycle, resulting in poor anti-blocking effect. Therefore, we propose a coal bunker anti-blocking air cannon to solve the above problems. Utility Model Content
