Description
Technical field
The utility model belongs to heated-air drying supply air system field, relates to the bright pearl heated-air drying of a kind of fireworks and firecrackers supply air system, is particularly useful for the heated-air drying of the bright pearl of fireworks and firecrackers and firework medicament.
Background technology
Fireworks and firecrackers is a kind of take pyrotechnic composition as raw material, makes and the recreational civil detonation product of formation through technique.In the fireworks and firecrackers in order to producing the firework medicament of various firework effects, by the multiphase solid mixture that oxidant and reducing agent etc. forms, energy generation sound, gas, light, look, cigarette texts during burning (blast).Therefore, be very strict to bright pearl in the fireworks and firecrackers production process and the requirement of firework medicament drying process, its baking temperature and hot blast wind speed should be controlled accurately, otherwise major industrial accident and occupational hazards can be caused.The drying of the bright pearl of China's fireworks and firecrackers and firework medicament mostly adopts daylight, steam drying and infrared ray or far infrared drying at present, these drying processes fall behind and need some protectors and special messenger to keep an eye on, production efficiency is low, poor product quality, but also exist the hidden danger of contaminated environment, occupational hazards and safety in production.
Summary of the invention
Problem to be solved in the utility model is, overcome the deficiencies in the prior art, the bright pearl heated-air drying of a kind of fireworks and firecrackers supply air system is provided, adopt the Intelligent hot blower fan as thermal source, the Intelligent hot blower fan is regulated the running frequency of air-heater, i.e. adjusting rotary speed accurately under the control of frequency converter and PLC, thereby regulate pressure and the air quantity of air-heater air-supply, guarantee to have enough hot blasts to use for the bright pearl of dry fireworks and firecrackers and firework medicament.
The utility model solves its technical problem and takes following technical scheme to realize:
The bright pearl heated-air drying of a kind of fireworks and firecrackers supply air system that provides according to the utility model, comprise Intelligent hot blower fan, blast pipe and discharge pipe, described Intelligent hot blower fan connects respectively blast pipe, discharge pipe, discharge pipe connects the gas transmission supervisor, on the gas transmission supervisor Pressure gauge is housed, gas transmission is responsible for one the tunnel and is connected gas transmission arm one, another road connects gas transmission arm two, hot blast control valve one is housed on the gas transmission arm one, hot blast control valve two is housed on the gas transmission arm two, many blowpipes in parallel have several wind pushing holes between gas transmission arm one and the gas transmission arm two on the blowpipe.
It is to take following technical scheme further to realize that the utility model solves its technical problem:
Keep at a certain distance away between the aforesaid wind pushing hole, the wind pushing hole diameter is ￠ 5.2～￠ 10mm.
The utility model compared with prior art has significant advantage and beneficial effect:
Because the utility model adopts the Intelligent hot blower fan as thermal source, the Intelligent hot blower fan is under the control of frequency converter and PLC, regulate accurately the running frequency of air-heater in 50Hz～120Hz scope, thereby air quantity and pressure in the heated-air drying supply air system have been regulated, for the drying of accelerating bright pearl and firework medicament has been created advantage.The wind pushing hole of reasonable Arrangement different-diameter size on many blowpipes of parallel connection is regulated the air-supply wind speed and is not more than 1m/s, makes the gas field in the drying box evenly appropriate, has improved the uniformity of drying effect.The utlity model has and force the gas transmission characteristics, anti-vibration performance is good, operates steadily, and noise is little, and is energy-conservation, and efficient is high.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, Intelligent hot blower fan, 2, blast pipe, 3, discharge pipe, 4, Pressure gauge, 5, the gas transmission supervisor, 6, hot blast control valve one, 7, hot blast control valve two, 8, gas transmission arm one, 9, gas transmission arm 2 10, blowpipe, 11, wind pushing hole.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof to foundation the utility model provides are described in detail as follows.
The bright pearl heated-air drying of a kind of fireworks and firecrackers supply air system as shown in Figure 1, comprise the Intelligent hot blower fan, blast pipe and discharge pipe, described Intelligent hot blower fan 1 connects respectively blast pipe 2, discharge pipe 3, discharge pipe connects gas transmission supervisor 5, on the gas transmission supervisor Pressure gauge 4 is housed, gas transmission is responsible for one the tunnel and is connected gas transmission arm 1, another road connects gas transmission arm 29, hot blast control valve 1 is housed on the gas transmission arm one, hot blast control valve 27 is housed on the gas transmission arm two, many blowpipes 10 in parallel between gas transmission arm one and the gas transmission arm two, have several wind pushing holes 11 on the blowpipe, keep at a certain distance away between the wind pushing hole, the wind pushing hole diameter is ￠ 5.2～￠ 10mm, and wind speed is not more than 1m/s to guarantee to blow.
Operation principle: Intelligent hot blower fan 1 is under the control of frequency converter and PLC, with 50Hz～120Hz frequency operation, fresh air enters the Intelligent hot blower fan from air inlet pipe 2, hot blast enters gas transmission supervisor 5 from escape pipe 3, hot blast is through Pressure gauge 4, hot blast control valve 1 and hot blast control valve 27 are by many blowpipes 10 air-supplies of gas transmission arm 1 and the two road direction parallel connections in 29 minutes of gas transmission arm.When sending hot blast, frequency converter and PLC accurately control the Intelligent hot fan operation in 50Hz～120Hz frequency range, thereby regulate hot blast rate and pressure in the heated-air drying supply air system, are conducive to the drying of bright pearl and firework medicament.Since on many blowpipes in parallel reasonable Arrangement wind pushing hole 11(￠ 5.2～￠ 10mm of different-diameter size) regulate the air-supply wind speed and be not more than 1m/s, make in the drying box evenly appropriateness of gas field, improved the uniformity of drying effect, also prevent the airborne dust of medicament.When after bright pearl and firework medicament drying process are finished, needing the medicine of a cold nature, frequency converter and PLC control Intelligent hot fan operation frequency are below 50Hz, this moment, the Intelligent hot blower fan was carried cool breeze in drying box, to reach medicine of a cold nature purpose, made the temperature of the bright pearl of fireworks and firecrackers and firework medicament less than 30 ℃.
