The utility model is not easily affected with damp, and the defects of failed ignition, etc. are avoided when the utility model is used by a display shell.
Description
One, technical field:
The utility model relates to the display shell launching tube, particularly discloses the smokeless launching tube of a kind of display shell, is applied in amusement with on the pyrotechnics product.
Two, background technology:
The fireworks display product of countries in the world all is as propellant powder with black powder at present.The fireworks display product of China still adopts traditional technology, and using has the jet-black gunpowder as propellant powder.Black powder is made up of potassium nitrate, sulphur and charcoal, therefore can produce a large amount of black smokes and sulfur dioxide foul smell, contaminated environment when emission.
The black powder emission dose of the spherical display shell of Japan is 1: 18～1: 20 with the throw-weight ratio, and the ratio of the traditional display shell of China is 1: 8～1: 10.
The principal charge parameter of tradition display shell,
| Caliber (time) | Body weight (gram) | Color pearl weight (gram) | Ignition powder weight (gram) | Booster weight (gram) | Black powder propellant powder weight (gram) | Propellant powder weight and throw-weight ratio |
| 3 | 162 | 30 | 22 | 42 | 24 | 1∶6 |
| 4 | 362 | 80 | 60 | 84 | 48 | 1∶7.5 |
| 5 | 665 | 180 | 120 | 160 | 60 | 1∶11.1 |
| 6 | 1145 | 290 | 200 | 300 | 120 | 1∶9.5 |
| 7 | 1900 | 520 | 300 | 600 | 140 | 1∶13.6 |
| 8 | 2800 | 700 | 500 | 1100 | 210 | 1∶13 |
| 10 | 5000 | 1000 | 1000 | 2000 | 360 | 1∶14 |
Three, summary of the invention:
The technical problems to be solved in the utility model:
1, uses smokeless propellant and be substituted with the jet-black gunpowder;
2, use plastics emission coyote hole and solve smokeless propellant flameholding problem;
3, applied metal pressure control sheet control chamber pressure problem.
The scheme that the utility model solves the problems of the technologies described above is as follows:
1, the combustion characteristics of black powder is can both burn rapidly under normal pressure or high pressure conditions, produces high temperature and high pressure gas.Traditional fireworks product is as long as pack quantitative black powder and fireworks product into, in case light the fireworks product of just lighting and dish out in the pipe at the end is arranged.
And smokeless launching tube is the standard commercially available prod, its smoulder under normal pressure, it is indoor it can only to be seated in the airtight propellant powder of plastics or steel, loads ignition charge and smokeless propellant respectively, but with electric ignition or paper fuse point of ignition gunpowder, its burning back high temperature and high pressure gas, the smokeless propellant that ignites, burning produces the more gas of high pressure rapidly, when shearing metal pressure control sheet, the gases at high pressure of discharging are transmitted into display shell in the air.
2, applied metal pressure control sheet is indoor for the circle metal plate of using 0.02～0.1mm, diameter 30～50mm is assemblied in the plastics propellant powder, and the pressure of control propellant powder chamber interior is just controlled ground gun pressure in the launching tube; Certain gun pressure, the display shell of weight unanimity must be transmitted into equal height.Key problem in technology of the present invention is to use known certain thickness metal pressure control sheet, the tensile strength of known metal sheet just, when gas pressure surpasses the mechanical strength that metal pressure control sheet can bear, the pressure control sheet is sheared, high temperature and high pressure gas promotes display shell and rises, and the blasting fuse of the display shell that ignites, just blast when reaching predetermined height, instantaneous formation fireworks pattern.
Therefore the utility model is achieved in that the smokeless launching tube of a kind of display shell, comprise launching tube, propellant powder and emission coyote hole, it is characterized in that: by emission coyote hole base, propellant powder constant pressure lid, metal pressure control sheet is formed airtight emission coyote hole, it is seated in the launching tube bottom, emission coyote hole base central circular open cavity is the emission coyote hole, filling smokeless propellant in the cavity, the circular metal pressure control sheet that equals the cavity internal diameter is stamped in emission coyote hole top, the propellant powder constant pressure covers emission coyote hole base and metal pressure control sheet, gland is provided with diameter less than emission coyote hole and the manhole directly over coyote hole, also is provided with on emission coyote hole base and launches ignition charge and the ignition lead passage that coyote hole is communicated with.Described metal pressure control sheet thickness is at 0.02～0.1mm, and material is selected a kind of in aluminium flake, bronze flake, latten(-tin).Described launching tube is the cylinder of uncovered, and the internal diameter specification has 20,30,50,75,100,125,150,180,200,225,250mm.
The utility model beneficial effect compared with prior art is: series of products of the present utility model all do not have harmful substances such as black smoke and sulfur dioxide when launching, and belong to environmentally friendly machine; It is indoor that smokeless propellant of the present utility model and ignition charge all are contained in airtight plastics emission coyote hole and metal propellant powder, so be not easy to make moist, avoided defects such as display shell misfire.
Four, description of drawings:
Accompanying drawing is the utility model display shell with smokeless launching tube profile.
In the drawings: 1, paper web or seamless steel pipe; 2, propellant powder constant pressure lid; 3, metal pressure control sheet; 4, smokeless propellant chamber; 5, igniting coyote hole; 6, electric ignition lead or firing cable channel; 7, emission coyote hole base; 8, display shell.
Five, the specific embodiment:
With reference to the accompanying drawings, the launching tube internal diameter has 20,30,50,75,100,125,150,180,200,225, many kinds of 250mm, it is combined with paper web or seamless steel pipe by plastics or steel emission coyote hole, when internal diameter is less than or equal to 100mm in the tube, use paper web and combine with plastics emission coyote hole, when internal diameter in the tube during more than or equal to 125mm the application seamless steel pipe launch coyote hole with steel and combine.Plastics emissions coyote hole is formed by injection molding by polypropylene or polyvinyl chloride or polystyrene plastics.Propellant powder indoor electric igniting or fuse ignite by the igniting coyote hole, and ignition charge is indoor also to load a small amount of ignition charge, emission coyote hole dress smokeless propellant, and metal pressure control sheet sealing is arranged at top, and the pressure control sheet is made by aluminium flake, bronze flake, latten(-tin).
During the display shell emission, energising is ignited electric igniter, the ignition charge that ignited at once, the ignition charge generation high temperature and high pressure gas smokeless propellant that ignited, this moment, the gas of higher pressure took place in the propellant powder space, when surpassing the tensile strength of metal pressure control sheet, metal pressure control sheet is sheared, and the high temperature and high pressure gas of emitting promotes display shell and rises, when reaching predetermined altitude, the display shell sky is quick-fried, forms fireworks pattern attractive in appearance.
