Description
Technical Field
The utility model relates to a fireworks apparatus for producing, especially a baking house return air safety device.
Background
When the fireworks powder is dried in the drying room, in order to save energy, the residual heat of the drying room is sent to the heating chamber through the air return opening of the drying room by the fan. As the drying room is filled with the fine firework powder, when the concentration of the fine firework powder is higher, the fine firework powder is conveyed into the heating room, detonation or explosion can occur, and safety accidents are caused.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a drying room return air safety device with simple structure.
The utility model adopts the following technical scheme.
A drying room air return safety device comprises a frame, wherein a piece of filter cotton is fixed in the frame, a screen is arranged beside the filter cotton, filter cloth is arranged beside the filter cotton, the filter cotton is wavy, and the mesh number of the screen is 160-180 meshes.
The drying room return air safety device is arranged on a return air inlet of the drying room or in a return air pipeline.
Compared with the prior art, the utility model has the advantages of simple structure prevents that slight fireworks medicine from sending into the heating chamber, has stopped the emergence of incident.
