Description

Technical Field

[0001] The invention relates to the technical field of powder spraying, in particular to an automatic powder spraying device. Background Art

[0002] Loading at the railway station is the last step in coal production and processing. However, in winter, when the outdoor temperature drops to minus 15 degrees Celsius, the commercial coal will be "frozen at the bottom" after loading. It is difficult to clean the frozen coal at the bottom during unloading at the port, which affects the unloading time. To avoid freezing of the commercial coal after loading, the coal preparation plant generally arranges a professional team for leveling the car. The operators use shovels or iron spades to manually sprinkle dry powder on the bottom of the empty car before loading. Since manual sandblasting cannot ensure that all the bottoms of the cars are evenly sprinkled, freezing still occurs from time to time.

[0003] Taking a coal preparation plant with a production capacity of 10 million tons as an example, an average of 12 trains are loaded every day, each with 60 carriages. Each carriage needs to be sprinkled with 25 kg of antifreeze powder. At least 20 personnel are required to take turns to spread dry powder every day. The labor intensity is high, and the spreading effect fluctuates greatly with the labor enthusiasm of the personnel. In addition, since the professional personnel of the leveling car need to tie and reinforce the car doors while spreading dry powder, there is cross-operation, which affects the loading efficiency. In addition, the antifreeze powder is easily spread unevenly during the operation, resulting in waste of materials and difficulty in ensuring the antifreeze effect.

[0004] In order to improve the above situation, the coal preparation plant installed powder spraying devices on its own, mainly winch-type and roller-type powder spraying devices. Personnel are required to carry the antifreeze powder to the platform and then manually pour it into the trough to realize the spraying operation. The antifreeze powder spraying devices currently used by each loading station are relatively backward in their powder spraying methods, with uneven spraying and difficult to control spraying amount, which easily leads to waste of antifreeze powder and freezing of the car, and the entire operation needs to be completed manually.
