Abstract
The utility model discloses an environmental-friendly inner barrel for fireworks. The environmental-friendly inner barrel for the fireworks comprises a barrel body which is formed in a compression moulding mode by effect medicine, a hollow cavity is arranged in the barrel body, explosives are placed in the hollow cavity, the hollow cavity is provided with at least one outward opening, a fire-passing fuse is mounted in the opening which is sealed by fire-passing mud, groove-shaped lines are arranged on the outer wall of the barrel body and evenly divide the barrel body into a plurality of protruding units, and a fireproof coating is arranged on the outer wall of the barrel body. According to the environmental-friendly inner barrel for the fireworks, a paper barrel is not used, only small amount of the fire-passing mud is needed, and therefore paper scraps can not be produced, and mud dust amount is greatly reduced. The groove-shaped lines are arranged on the outer wall of the barrel body and enable demoulding to be easy, and the number and the shapes of the protruding units are not limited by manufacturing technology. The shape of the barrel body and the groove-shaped lines can be arranged freely, and a foundation is established for creating abundant and variable models in the air.
Description
Technical field
The utility model relates to the fireworks and firecrackers field, especially a kind of fireworks inner tank.
Background technology
Fireworks inner tank claims again effect tube.In the prior art, fireworks inner tank is to adopt paper web, and the paper web port installs effect medicine and blast medicine, and overshoot lead wire is set with mud head capping constraint in the paper web.Deliver to the high-altitude by urceolus (launching tube), igniting to explode by overshoot lead wire simultaneously tells on.
Its drawback is, can produce a large amount of paper scraps, earth dust after existing fireworks inner tank is seted off, and is very big to the pollution of setting off ground, and is difficult to remove.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of fireworks environmental protection inner core is provided, and on the basis that keeps original firework effect, can not produce paper scrap after setting off, and the earth amount of dust also greatly reduces.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that a kind of fireworks environmental protection inner core comprises the cylindrical shell that adopts the compression molding of effect medicine; In the described cylindrical shell cavity is set, cavity inside is put the blast medicine; Cavity is provided with at least one external opening, and opening is installed overshoot lead wire and covered with the mudding that overdoes; Described cylinder body outer wall arranges the channel form lines, and described channel form lines is divided into some protrusion element with the cylindrical shell equilibrium; Described cylinder body outer wall arranges fire resistant coating.
Described cylindrical shell can be arbitrary shape, and preferably shape is spherical, cylindrical, oval.
Adopt the effect medicine compression molding that technique scheme, described environmental protection inner core directly adopt to be needed, pack into the operation of launching in the urceolus of described environmental protection inner core is consistent with prior art, and fire resistant coating guarantees that making and emission process thereof are not lighted.Explosion time, some protrusion element of cylindrical shell are along the decomposition of channel form lines and lighted a plurality of separate effect points of burning formation aloft.Its beneficial effect is, has abandoned the use of paper web, only needs the chamotte of crossing of minute quantity, thereby can not produce paper scrap, and the earth amount of dust also greatly reduces; The channel form lines is arranged at cylinder body outer wall makes its demoulding easy, and the quantity of protrusion element and shape are not limited by manufacture craft; Cylindrical shell shape and channel form lines can arrange arbitrarily, enrich changeable skydive for creation and lay a good foundation.
Effect medicine die press technology for forming is with that the effect medicine is pressed into the bright pearl of graininess is similar.Consider its mouldability and decomposability but the utility model will have concurrently, based on the consideration of performance optimization, more excellent selection is that the glue that adopts celluloid and organic solvent to be made into mixes again compression molding with the effect medicine.Organic solvent is such as alcohol, ether, acetone, ethyl acetate etc.Further, its proportioning of comparatively optimizing is: by ratio of weight and the number of copies, and effect medicine 85-95 part, celluloid 5-15 part, organic solvent 10-20 part.
Preferably, the volume of described cavity is according to the volume setting of blast medicine.
Preferably, the smokeless bursting charge of described empty intracavitary unit, described effect medicine adopts smokeless effect medicine.Smokeless bursting charge and smokeless effect medicine all can be buied in the firework raw material market, also can be referring to following Chinese utility model patent document, and the utility model quotes in full following file:
1. title: 101481285 open days on July 15th, 2009 of micro-smoke firework bright bead with tail publication number CN;
2. title: 101481287 open days on July 15th, 2009 of micro-smoke colorful bright bead for firework publication number CN;
3. title: 101481287 open days on Mays 11st, 2011 of a kind of micro smoke gun propellant for fireworks publication number CN.
Adopt smokeless medicine so that environmental protection inner core described in the utility model is realized is smokeless, without the environment protecting of paper scrap, micronic dust.
Cross the preferred yellow mud of chamotte and crushed crude pearlite mixing manufacture to guarantee its fragility, preferred proportioning is: by ratio of weight and the number of copies, and yellow mud 50-100 part, crushed crude pearlite 0-50 part.
The preferred fire resistant coating of described fire resistant coating consists of.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the utility model specific embodiment cross-sectional view.
The specific embodiment
Referring to accompanying drawing, reflect a kind of concrete structure of the present utility model, described fireworks comprise cylindrical shell 1 with the environmental protection inner core, the described cylindrical shell 1 interior cavity 3 that arranges, the cavity 3 interior devices medicine that smokelessly explodes, cavity 3 is provided with an external opening 9, and opening 9 is installed overshoot lead wires 5 and was also used chamotte 4 cappings; Described cylindrical shell 1 outer wall arranges channel form lines 6, and described channel form lines 6 is divided into some protrusion element 7 with cylindrical shell 1 equilibrium; Described cylindrical shell 1 outer wall arranges fire resistant coating coating 8.
Described fireworks with the preparation method of environmental protection inner core are: 1. the ratio that takes by weighing by weight 75 parts of yellow mud, 25 parts of crushed crude pearlites mixes and namely got chamotte.2. the medicine that smokelessly explodes can adopt following prescription: nickel hydrazine nitrate 7-35 part by ratio of weight and the number of copies, and nitrocotton 65-93 part, conventional method mixes and gets final product.3. first need the allocative effect medicine according to effect, again celluloid and acetone are made into glue, glue and effect medicine mix, and proportioning is: by ratio of weight and the number of copies, and 90 parts of effect medicines, 10 parts of celluloids, 15 parts in acetone.With mixture patrix pressing formation, coat fire resistant coating after the demoulding drying, reinstall smokeless blast medicine, load onto overshoot lead wire also with the mudding cover gab that overdoes, described fireworks are namely made complete with the environmental protection inner core.
The above-mentioned embodiment that the utility model is described only is for the technical solution of the utility model clearly is described, and can not be interpreted as the utility model is made any restriction.The utlity model has known multiple alternative and distortion, such as arranging of cylindrical shell shape and channel form lines etc., under the prerequisite that does not break away from the utility model essential meaning, all fall into protection domain of the present utility model.
