Efficient firework powder drying system

Abstract

The invention discloses an efficient firework powder drying system. The firework powder drying system adopts an active vacuum dehumidification mode and comprises a material drying system, a dehumidification and exhaust system, a heat dissipation system and a heat source system. The dehumidification and exhaust system is located on one side of the outer part of the material drying system and fixedly connected with the material drying system, and the material drying system and the dehumidification and exhaust system are connected and communicate with each other through a pipeline. The heat dissipation system is located in an underground sunken area corresponding to the material drying system, a grid floor structure is connected between the heat dissipation system and the material drying system, the grid floor structure is used for enabling the heat dissipation system to dissipate hot air to the material drying system from bottom to top for heating, and the heat source system and the heat dissipation system are connected into a whole through a heat source pipeline. Radiating fins are seamless steam radiating fins, the heat efficiency is high, active heating can be realized, and the problems of passive heating, high cost, low heat efficiency and the like in the prior art are solved.

Description

Technical field [0001] The present invention belongs to a powder dried apparatus, and specifically, a highly efficient drying fireworks powder system. Background technique [0002] In the prior art, the drying chamber for dry use of fireworks is generally used by passive dehumidification drying methods. Whether it is a hot air circulation or straightforward way, it involves dynamic flow of hot air, and in the drying chamber, pyrotechnic drug dust Dry hot air movement, precipitation accumulate in the airway of the drying chamber, or new wind delivery, easy to produce static electricity, form a safety hazard, once in case of rubbing, explosion is triggered. For example, "a static fireworks dehumidification and drying system" announced by the National Intellectual Property Office, has been approved by the State Intellectual Property Office, the authorization notice number is: CN105202872B, the shortcomings of the invention are: 1, dry A three-layer water circulating hot coil is prov...

Problems solved by technology

[0002] In the prior art, the drying room used for drying fireworks drug powder generally adopts the passive dehumidification drying method. Whether it is the hot air circulation method or the direct discharge method, it involves the dynamic flow of hot air. In the drying room, the pyrotechnic drug dust is Due to the movement of dry hot air, the sediment accumulates in the air duct of the drying room, or when fresh air is sent in, it is easy to generate static electricity and form a safety hazard. Once there is friction, it will cause an explosion hazard

For example, the invention patent "A Static Pyrotechnic Powder Dehumidification and Drying System" disclosed in the patent literature of the State Intellectual Property Office has been approved and authorized by the State Intellectual Property Office. The authorization announcement number is: CN105202872B. The disadvantages of the invention patent are: There are three layers of water circulation cooling coils stacked up and down on the side walls around the room. The water circulation cooling coils are connected to the heat preservation water tank through the water pump. The heat preservation water tank is equipped with a heat pump heating unit and an electric auxiliary heating device. The process is relatively complicated and the drying time is long. Generally, one ton of wet medicine takes more than 40 hours, and the output is low; 2. The heat dissipation coil adopts an E-shaped copper coil fin radiator. The radiator with this structure is easy to accumulate dust, is not easy to clean, and consumes high power. Because the heat dissipation area is not concentrated enough, the thermal efficiency is not high, and the investment is large, the cost of the whole set of equipment is high; 3. Due to the use of a number of drainage holes on the ceiling of the drying room, it is easy to cause damage to the water surface connected to the dust collection pool through pipelines. Safety hazard, the gas and dust discharged to the outside will pollute the surrounding environment, which is not conducive to dehumidification, especially in rainy days, which will affect the dehumidification effect of the top; 4. The fresh air in the dehumidification process of the drying room is the evaporation of the heat pump unit It is easier to cause the generated dust to cause combustion and explosion
