Detailed Description
Referring to the attached drawings, a concrete structure of the invention is reflected, the explosion-proof workshop for producing fireworks and crackers comprises a workshop 3 body arranged in a mountain protection barrier 1, pressure water provided by a high-level water tank 7 is sequentially connected with a top sprinkler 10, a right sprinkler 11 and a left sprinkler 12 in three workshops 3 through a main pipe 6, a main pipe valve 5, a branch pipe 2, a shunt valve 4, a shunt pipe 8 and a wall penetrating pipe 9, wherein the top sprinkler 10 is positioned above a workbench 13 of an operation station of the workshop 3.
The three sprinklers are mounted at different positions, but have the same structure, and the left sprinkler 12 will be described as an example. The left sprinkler 12 is a disk with a diameter of 0.5 to 1.5 m; the latex or plastic film 1204 closes the water outlet 1201 of the sprinkler 12 to form a vulnerable and fusible closed port: the periphery of the film 1204 is fixed on a ring 1203, and the ring 1203 is connected with the water outlet 1201 through threads 1202 to form a convenient and reliable film fixing mode. The material and/or thickness of the membrane 1204 may be selected as desired, based on the criteria that it will not break under normal (non-accident) water pressure, but will break relatively quickly after pressurization.
In other embodiments, the membrane 1204 of the sprinkler 12 may have normally open nozzles oriented at different angles, the nozzles communicating with the sprinkler inlet. Under normal condition, the water from the nozzle is collected in the disc-shaped inner cavity of the sprinkler and is sealed by the film 1204; when an accident happens, the film 1204 is damaged, and the nozzles spray water to all directions in the plant to extinguish fire and reduce temperature, so that the spraying strength and the spraying range of water are improved.
In this example, a protruding area 1205 is arranged at the center of the film 1204, and priming powder is adhered to the protruding area 1205; thereby effectively improving the reliability, sensitivity and reaction speed of the flame-sensing fusing damage reaction of the film 1204 when a fire disaster occurs. Although the arrangement of the priming powder increases the hazard source of the workshop, the pyrotechnic composition operation is carried out in the pharmaceutical line workshop, the amount of the priming powder coated on the film at the position is very small, the medicament cannot explode, the risk is low, the comprehensive advantages and disadvantages are not considered, or a certain safety value is possessed, and the priming powder can be considered and selected according to the situation in practice.
In this example, the main valve 5 is normally open and fully open, the shunt valve 4 is an automatic valve, and the automatic valve is arranged on a water pipe outside the workshop 3; a temperature sensor (not shown in the figure) is arranged in the workshop 3; the shunt valve 4 is set to an opening degree according to a signal of the temperature sensor. When a fire disaster occurs, the shunt valve 4 is automatically opened to a full-open position according to a signal of the temperature sensor, the pressure at the water outlet 1201 is increased, and the material and/or thickness of the corresponding film 1204 are/is set according to the pressure, so that the purpose of directly expanding and breaking the film by utilizing the water pressure is realized. To further ensure the rupture of the membrane 1204, a knife 1206 is fixed to the ring 1203, and the edge of the knife 1206 faces and is close to the membrane 1204. The knife edge faces and is close to the membrane, the membrane 1204 can not be damaged in normal contact, when the pressure at the water outlet 1202 is increased, the membrane 1204 is contacted with the knife edge when being pressed and protruded, the membrane 1204 is scratched by the knife edge, and the membrane 1204 is rapidly broken. When a combustion accident or accident is happened in the production workshop 3 for fireworks and crackers, a large amount of water is released for extinguishing fire and reducing temperature. Provides a powerful means for stopping and interrupting the accident development; the explosion accident in the workshop 3 is effectively prevented; the loss in the workshop is reduced; the escape opportunity is increased for the staff.
The above-mentioned implementation is only for clearly illustrating the technical solutions of the present invention, and is not to be construed as limiting the present invention in any way. The present invention has many known alternatives and modifications in the art, which fall within the scope of the present invention without departing from the spirit of the present invention.
