Description

The forming method of a kind of fireworks pyrotechnic medicine and former thereof
Technical field
The present invention relates to forming method and the former thereof of a kind of fireworks pyrotechnic medicine.
Background technology
At present in fireworks industry, still using manual mode of operation in the granulating and forming practice of pyrotechnic composition, it is raw Produce efficiency and safety is extremely low.In existing relevant device researchs and develops, either use cylinder or rolling disk Pelletize, or use method for rotational extrusion pelletize, in completing the work process that molding is relevant, all it is difficult to avoid that Friction and Extrusion the most repeatedly between pyrotechnic composition and equipment and between pyrotechnic composition, the company of this friction and Extrusion Continuous repetitive process is exactly that the process of accumulation heat in pyrotechnic composition, accumulation of heat and the temperature rise caused thereof constitute Potential safety hazard, easily causes security incident to occur.
Summary of the invention
In order to solve above-mentioned drawback, the technical problem to be solved is to provide a kind of safe fireworks The forming method of pyrotechnic composition, it is possible to avoid the accumulation of heat of pyrotechnic composition and equipment thereof.It addition, the present invention also carries Supply former corresponding with above-mentioned forming method.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is, the one-tenth of a kind of fireworks pyrotechnic medicine Type method, it is characterised in that comprise the steps:
Step one: addition 6~the water of 10%, mix homogeneously form slurry in pyrotechnic composition to be processed by weight;Excellent Selection of land, the addition of described water is the 7~9% of pyrotechnic composition weight to be processed, especially 8%;
Step 2: slurry is sent between the compression roller roll gap of a pair active rotation in opposite directions, makes slurry be squeezed into Closely knit sheet stock;
Step 3: sheet stock sends into crushing mechanism, the material being broken falls into and multistage is sieved to carry out less two-stage screening, Material after Po Sui is screened into large granule, suitable particles and fine particle, fine particle on multistage sieve Reclaim circulation and enter back into step 2 extruding;Large granule continues broken being then further continued for and sieves;Suitable particles warp It is dried and is molding pyrotechnic composition.
The former of a kind of fireworks pyrotechnic medicine, including pyrotechnic composition humidification mechanism and slurry hopper, its feature It is, below the discharging opening of described slurry hopper, is connected the compression roller of a pair active rotation in opposite directions, compression roller Roll surface be copper smooth roll surface;The breaker roll of a pair active rotation in opposite directions, breaker roll are set below compression roller Roll body on be distributed some crushing rods, described breaker roll roll surface and crushing rod are copper material;Described breaker roll Being installed in the splicing basin that one-level screen cloth is constituted, two grades of screen clothes of device below splicing basin, described screen cloth is copper Material.
Preferably, the forming method of described a kind of fireworks pyrotechnic medicine, it is characterised in that comprise the steps:
Step one: add the water of 8%, mix homogeneously form slurry by weight in pyrotechnic composition to be processed;
Step 2: slurry is sent between the roll gap of compression roller through hopper, makes slurry be squeezed into closely knit sheet Material;
Step 3: sheet stock falls between breaker roll, sheet stock is crushed by the crushing rod that two breaker rolls are mutually twisted For large granule, suitable particles and fine particle, large granule continues in staying the splicing basin that one-level screen cloth is constituted Continuous broken being then further continued for is sieved;Fine particle falls into splicing chute after secondary vibration screen cloth, sequentially passes through Material collecting box for harvesting, recovery conveyer belt are sent hopper recovery circulation back to and are entered back into step 2 extruding;Suitable particles stays two On level vibrosieve mesh screen, after collection, it is molding pyrotechnic composition through dry.
The beneficial effects of the present invention is, 1. safety is greatly improved: equipment is all one to the processing of pyrotechnic composition Secondary property is processed by formula, and the most repeatedly, pyrotechnic composition does not has accumulation of heat or thermal accumlation the least, will not lead Cause temperature raises, and thoroughly eliminates this potential safety hazard;2., after slurry is squeezed, its granule will carry out weight Row, and discharge intergranular air, thus reduce the space of storeroom, it is achieved pyrotechnic composition performance, through broken The surface imperfection granule of rear formation, its surface area to be far longer than the surface area of existing pearl or cylindrical particle, Its initial combustion face is greatly increased, and the performance that pyrotechnic composition moment is ignited is greatly improved;3. wet method makes and carries Having supplied further safety guarantee, copper material eliminates Electrostatic Hidden Troubles;4. its device structure is simple, takes up an area Area is little, it is easy to Operation and Maintenance, not only increases the economy of equipment, has ensured life the most from many aspects simultaneously The safety produced.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Accompanying drawing explanation
