Description
Technical Field
The invention belongs to a safe firework shell, a firework shell launching device and a system.
Background
Fireworks are a familiar article for Chinese people. The traditional fireworks are made of gunpowder and metal powder as main raw materials, and after ignition, the fireworks produce the effects of light, sound, color, type, smoke and the like through combustion or explosion, are used for viewing and enjoying, and are flammable and explosive.
Wherein, the luminous effect is a main effect of the firework powder. By utilizing the high temperature and luminous effect generated after the metal powder in the firework powder is combusted, the metal powder (such as aluminum powder, magnesium aluminum alloy powder and the like) in the medicament can release a large amount of light energy and heat radiation when the medicament is combusted, the luminous intensity is hundreds of thousands of international candles, and the temperature can reach thousands of degrees. The lighting agent or the flashing agent which can produce light stars can produce flashing effect agents which are flash and extinguish, and the firework effect produced by the lighting agent or the flashing agent can not deviate from the luminous effect of metal burning. The harm of fireworks and crackers to the environment is mainly air pollution and noise pollution. Due to gunpowder components in the fireworks and crackers, safety accidents often occur in various links of production, transportation, storage, setting off and the like of the fireworks and crackers due to negligence and violation.
Gunpowder in the traditional firework powder mainly comprises propellant powder and combustion-supporting powder, the propellant powder has the function of generating high-temperature and high-pressure gunpowder gas, the high pressure launches a firework shell into the air, and meanwhile, the high temperature is utilized to ignite the firework shell. The combustion-supporting powder can help metal powder in the fireworks and firecrackers to continuously and violently burn in the air and release strong light and a large amount of heat energy.
However, gunpowder in the traditional fireworks is a dangerous explosive, and accidents can be caused by carelessness in the links of production, transportation, storage and the like. In fact, the number of deaths from various accidents in the firework and cracker industry is high every year. If the gunpowder in the pyrotechnic composition is carefully examined, the gunpowder is only used for assisting the burning and luminescence of metal powder (magnesium powder or magnesium-aluminum alloy powder) and is not an indispensable component.
In addition, the main components of gunpowder in the traditional fireworks are sulfur, charcoal and an oxidant (generally made of saltpeter), a large amount of toxic gases such as sulfur dioxide, sulfur monoxide, nitrogen dioxide and nitrogen monoxide can be released in the process of setting off, and a large amount of carbon black dust can be released by incomplete combustion of charcoal. Every time fireworks are set off in festivals and celebrations, serious air pollution problems can be caused.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
The first embodiment is as follows:
the invention relates to a non-gunpowder safe environment-friendly firework which comprises a firework shell and a corresponding firework shell launching device, wherein the firework shell mainly plays a role in burning in the air to emit strong light and present various firework effects.
The firework shell launching device adopts a physical method to replace the action of gunpowder components in fireworks, and the launching equipment utilizes electric energy to generate high temperature and high pressure to heat and launch the fireworks shell into high altitude to burn and emit light.
The main process is as follows:
the whole or part of the firework shell is heated to the temperature above the ignition temperature of the components by using the firework shell launching device, then the firework shell is launched in the air by using high-pressure gas, and after the firework shell contacts the air in the air, a large amount of strong light and heat energy are released, so that various flowery firework effects are formed.
The safety fireworks shell is made into an oval shape as shown in fig. 1, but of course, can be made into various shapes such as a round shape and a cylindrical shape according to requirements, and is not described in detail herein.
Unlike fireworks in the prior art, the inner body 601 of the present invention does not contain any gunpowder component, and is mainly a block formed by pressing or mixing and smelting combustible metal powder particles, flame color powder particles and/or effect agent powder particles, and the combustible metal powder particles are heated to the ignition point thereof to emit light, and for this purpose, the melting point of the protective layer is required to be higher than the ignition point of the combustible metal in the inner body.
Generally, the protective layer is an inorganic adhesive sheet or a metal sheet, but any material having a melting point higher than that of the combustible metal in the inner body can be selected as required, such as: clay, glass, etc. In addition, when the safe firework shell launching device is used for launching the firework shell, the firework shell needs to be exploded in the high altitude, and therefore, the protective layer needs to be easily broken by high-pressure gas, and therefore, the thickness of the protective layer needs to be controlled.
According to a plurality of tests of the applicant, when the inorganic glue is selected, the thickness of the inorganic glue sheet is 1.5-2 mm; when a metal foil is selected, the thickness of the metal foil is 0.5-1 mm. The thickness is 1-1.5mm when china clay is selected, and 0.5-1mm when glass is selected.
According to the experience of the applicant, the general combustible metal powder particles are selected from one or a combination of pure magnesium powder particles, pure aluminum powder particles or magnesium aluminum alloy powder particles, and the materials are also commonly used for luminescence in the existing fireworks. Of course, other materials, such as other types of metals or alloys, such as titanium, may be selected instead.
In addition, the flame color agent powder is one or a combination of sodium chloride, potassium chloride or strontium chloride powder. The particles of the effect agent are selected from copper oxide and/or bismuth oxide.
The firework shell needs to be launched by combining a specific launching device.
As shown in fig. 2, the safety fireworks projectile launching device of one embodiment matched with the present invention mainly comprises: a high temperature heating system and a high pressure gas emission system, the high pressure gas emission system comprising: the launching tube 1 is used for placing the fireworks 3, the outer diameter of the fireworks 3 is matched with the inner diameter of the launching tube 1, and basically no space exists between the fireworks and the launching tube. In the embodiment, the emitter tube 1 is made of a metal tube or a ceramic tube, and the inner wall is smooth.
The high-pressure gas emission storage device 2 is used for providing high-pressure gas to push the fireworks bomb out of the emission tube and break the protective layer so as to explode and generate fireworks in high altitude, and is connected with the bottom of the emission tube through a pipeline;
a high-pressure air valve 3 is arranged on the pipeline;
the high-temperature heating system is connected with the launching tube, heats one part or all of the launching tube, transfers heat to the firework shell through the launching tube, heats combustible metal powder particles in the firework shell to a temperature above a burning point, pushes the firework shell out of the launching tube by high-pressure gas after the combustible metal powder particles reach the burning point, breaks through the protective layer, and explodes and generates fireworks in high altitude.
In the embodiment, the high-temperature heating system is selected to be electrically heated, and of course, other heating systems may be selected, which are not described herein. As shown in fig. 2, the heating system includes a heating element 5, which is disposed inside the launch tube, or integrated with the launch tube, or disposed outside the launch tube and attached to the launch tube, in the embodiment, an electric heating wire is selected, and the heating wire is disposed outside the launch tube, and closely attached to the launch tube, and heats the launch tube.
Based on the above embodiments, the technical advantages of the present invention can be seen. That is, the safe firework shell does not contain any gunpowder component, and the components of the safe firework shell are common combustible industrial raw materials, so that the safety problem of fireworks is fundamentally solved. In addition, the firework shell is launched into the air and ignited by using other physical and chemical methods to replace the effect of gunpowder, and the firework shell has safe and reliable effects.
Example two:
in order to realize the effect of automatic control, the invention can be additionally provided with a control system which can be realized based on a single chip microcomputer/PLC/computer/mobile phone/mobile tablet and is mainly used for controlling the opening and closing of the high-pressure air valve. Specifically, the control system may be connected to the high-temperature heating system and the high-pressure gas emission system, sense the temperature of the emission tube transmitted by the high-pressure gas emission system through a temperature sensing unit, control the high-pressure gas emission system to open the high-pressure gas valve after the temperature reaches a set temperature, and close the high-pressure gas valve after the emission bomb is emitted.
Example three:
the components of the firework shell can be randomly matched according to the required effect, for example, in one embodiment, the components of the firework shell are as follows: metal (magnesium, magnesium aluminum alloy) and flame coloring agent (sodium chloride, potassium chloride, strontium chloride, etc.), and the powders of the two components are uniformly mixed and pressed into blocks, or are mixed and melted into the block-shaped firework shell at high temperature. The surface of the firework shell is coated with a protective layer, and the protective layer is made of materials which can resist high temperature and have proper strength at high temperature, such as: high-temperature inorganic glue commonly used in industry, etc.
When the firework shell is launched, the firework shell is loaded into the firework shell launching device, the launching equipment heats the firework shell to be above 700 ℃, and at the moment, metal (magnesium and magnesium-aluminum alloy) in the firework shell is molten into a liquid state (the ignition point of magnesium is 500 ℃ and the melting point is 660 ℃) and reaches the ignition point or above.
Because the protective layer on the surface isolates and contacts the liquid metal and the air in the firework shell, the firework shell cannot start to burn in the launching device. When the high-pressure gas is used for shooting the fireworks bomb out of the launching tube by the launching device, the protective layer of the fireworks bomb is broken due to the strong impact force of the high-pressure gas flow and the impact effect with the wall of the launching tube, the high-temperature liquid metal mixed flame toner in the fireworks bomb is launched into the air and is scattered into small lumps, and the small lumps are in contact with the air and are violently combusted to form the scattered fireworks effect.
The novel fireworks in the invention have no gunpowder, and the components of the novel fireworks are common combustible metal industrial raw materials. The firework shell without gunpowder is not a dangerous explosive, but a common combustible, and fundamentally solves the safety problem of fireworks.
Example four:
in one embodiment, the composition of the fireworks shell is: metal (magnesium) and flame color agent (sodium chloride, potassium chloride, strontium chloride, etc.), and the powders of the two components are uniformly mixed and pressed into blocks, or mixed and smelted into the block-shaped firework shell at high temperature.
When the fireworks shell is launched, the fireworks shell is loaded into the fireworks shell launching device, and the launching equipment heats a launching pipe component to above 700 ℃, but the fireworks shell is not heated to a burning point.
When the mechanical mechanism for the launching equipment is filled the fireworks shell to the launching tube, the fireworks shell begins to heat up under the action of high-temperature heat transfer of the launching tube, the fireworks shell is heated for a certain period of time, when the temperature reaches the temperature above the ignition point and begins to violently burn, the launching equipment immediately launches the fireworks shell into the air by high-pressure gas, the fireworks shell contacts with air and continues to violently burn, and the effect of the colorful fireworks shell which slowly rises is formed.
The novel fireworks in the invention have no gunpowder, and the components of the novel fireworks are common combustible metal industrial raw materials. The firework shell without gunpowder is not a dangerous explosive, but a common combustible, and fundamentally solves the safety problem of fireworks.
Example five:
in this embodiment, the composition of the fireworks shell is: metal (magnesium), flame color agent (sodium chloride, potassium chloride, strontium chloride and the like) and effect agent (magnesium-aluminum alloy, copper oxide and bismuth oxide, the effect agent commonly used for the traditional fireworks can release a large amount of gas to explode at a certain high temperature), the metal and the flame color agent powder are uniformly mixed, and the mixture is coated on the inner body to prepare the spherical firework shell.
When the fireworks shell is launched, the fireworks shell is loaded into the fireworks shell launching device, the launching tube component is heated to above 700 ℃, and the fireworks shell is not heated at the moment. When the mechanical mechanism for the launching equipment is used for filling the fireworks shell into the launching tube, the fireworks shell begins to heat up and burn under the action of high-temperature heat transfer of the launching tube, once the fireworks shell begins to burn violently after being heated for a certain period of time, the launching equipment immediately launches the fireworks shell into the air by using high-pressure gas, the fireworks shell contacts with the air and burns violently, and the effect of a color lighting shell rising slowly and slowly is formed. The high temperature of the fireworks makes the inside effect agent release a large amount of gas to explode, explodes the fireworks shell and forms the fireworks effect of scattering to the periphery.
In a word, the firework ignition point is the ignition point of metal components in the firework ignition point, is about 400-500 ℃, is higher than the ignition point (150-300 ℃) of common combustible materials such as paper, clothes and the like, and has better safety.
Moreover, gunpowder in the traditional fireworks can release a large amount of toxic gases such as sulfur dioxide, sulfur monoxide, nitrogen dioxide, nitrogen monoxide and the like in the process of firing, and a large amount of carbon black dust can be released due to incomplete combustion of charcoal. The setting off of fireworks can cause serious air pollution problems. The safe and environment-friendly firework disclosed by the invention is very simple and safe in components, and the product after being set off is magnesium oxide, so that no product harmful to human bodies is generated.
In addition, when traditional fireworks are set off, the gunpowder combustion explosion can produce huge sound, and can have strong noise interference to the residents around. After the gas is completely set off, a large amount of paper scraps and garbage are generated, and the cleaning work is very heavy. The environment-friendly safe firework has small sound when being set off and small interference to surrounding residents; and a large amount of paper scraps and garbage can not be generated, and the problem of secondary pollution of the traditional fireworks to the surrounding environment is solved.
Meanwhile, the firework bullet launching device can use energy sources such as fuel gas to replace electric power when generating high temperature, and a gas tank filled with high-pressure gas can be used at high pressure. The fireworks can replace magnesium and magnesium-aluminum alloy with other kinds of metal or alloy such as titanium, and the material which can keep proper strength can be used as a protective layer, wherein the material does not change when contacting air at high temperature, and comprises the following components: pottery clay and glass, which are not described herein.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
