Description
Technical Field
[0001] The utility model relates to the technical field of pyrotechnic powder processing, in particular to a water heat storage type hot air device in a pyrotechnic powder drying room. Background Art
[0002] Gunpowder, also known as black powder, is a mechanical mixture of potassium nitrate, charcoal and sulfur. Under the action of appropriate external energy, it can burn rapidly and regularly, while generating a large amount of high-temperature combustion gas. Gunpowder is the basic raw material for making fireworks. When producing fireworks, the gunpowder needs to be dried to remove the internal moisture to form a dry powder.
[0003] The existing dryer starts the air source heat pump, directly heats the air through the condenser, and then uses the fan to make the hot air flow through the items to be dried to take away moisture, thereby drying the items. However, when this equipment is in use, for safety reasons, the heat pump and the drying room are kept at a certain distance, but the condenser must be close to the drying room. If there are risks such as fluid leakage, leakage and working static electricity, it will affect the safety of the drying room.

[0029] Two ball valves 300 are arranged on the support frame 101, and the ball valves 300 are connected to the water inlet pipe 301 and the drainage pipe 302 respectively. The surfaces of the water inlet pipe 301 and the drainage pipe 302 are provided with a plurality of conduits 303, and the ends of the conduits 303 are connected to the fin heat exchanger 304. A bracket 305 is arranged on the inner wall of the wind cabinet 100, and a fin heat exchanger 304 is arranged on the upper end of the bracket 305. When in use, the ball valve 300 is turned on to make the water inlet circulation pipe 206 and the water inlet pipe 301 The outlet water circulation pipe 207 is connected with the drain pipe 302.

During this process, the dust collecting net 504 arranged between the inner walls of the return air duct 503 can prevent the fireworks powder inside the drying box 501 from entering the wind cabinet 100. The remaining hot air will have some residual heat and water vapor carried during the drying process. At this time, the heat recovery core 403 will absorb the remaining residual heat for recycling, and then start the dehumidification fan 400 to absorb the water vapor contained in the air, so that the absorbed water vapor is converted into condensed water and enters the collection box 401 for collection, and then discharged from the water outlet pipe 402.
