technical field

The invention relates to the field of firecrackers and fireworks, in particular to a blasting workshop to the sky.

Background technique

Fireworks are actually similar in structure to firecrackers, and their structures both contain black powder and powder. In order to achieve a good performance, fireworks and shells are filled with a large amount of gunpowder for launching and exploding. For example, after a shell with a diameter of 20 cm is launched, it will explode at an altitude of about 200 meters. These stars can cover a radius of about 80 meters.

In the production of firecrackers and fireworks industry, there is a possibility of drug explosion in the workshops containing pyrotechnics, while traditional workshops use lateral and straight venting. secondary damage.

Further, the explosion-proof door is installed on the inner side of the wall of the explosion-venting workshop. The explosion-proof door is installed on the inner side of the wall of the explosion-proof workshop, and the explosion-proof door is opened by horizontal push.

Further, the explosion-proof door is a stainless steel plate explosion-proof door.

The working principle of the present invention is as follows: an internal explosion test is carried out through the anti-explosion chamber of the steel plate structure and the anti-explosion chamber of the concrete structure through which the pressure is released at the top, and the anti-explosion performance is verified through the measurement result strain and macroscopic observation; Shock wave overpressure and impulse distribution, measure the ground shock acceleration generated by the explosion, and analyze the shock wave overpressure and the damage to nearby personnel.

After the above technical scheme is adopted, the beneficial effects of the present invention are as follows: it adopts the explosion venting to the sky, the structure is reasonable, the explosion venting performance and safety performance are improved, the adjacent equipment will not be killed in a series of explosions, and the surrounding construction environment and personnel will be avoided. secondary damage.

Detailed ways

1-4, the technical solution adopted in this specific embodiment is: it comprises a bottom plate 1, an explosion venting workshop wall 2, an explosion-proof door 3, and the upper end of the bottom plate 1 is provided with four explosion venting workshop walls 2, four The walls 2 of the explosion venting workshop are connected end to end, and the front end of the wall 2 of the explosion venting workshop is provided with an explosion-proof door 3; The notch on the upper surface is rectangular; the blasting workshop wall 2 is a flat rectangular blasting workshop wall; the top notch of the blasting workshop wall 2 is not closed.

The explosion-proof door 3 is installed on the inner side of the wall 2 of the explosion-venting workshop. The explosion-proof door 3 is installed on the inner side of the wall 2 of the explosion-venting workshop, and the explosion-proof door 3 is opened by a horizontal push type, and the explosion-proof door 3 is clamped with the wall 2 of the explosion-venting workshop.

The explosion-proof door 3 is a stainless steel plate explosion-proof door.

The wall 2 of the explosion venting workshop is made of reinforced concrete.

There are five models in this test, which are arranged in a ring shape, with a radius of 5m, and a schematic diagram of the plane layout (see Figure 2). 7m, 10m, the sensor measuring surface is installed horizontally; in Figure 4, the measuring surfaces of P1-1~P1-5 measuring point sensors are arranged vertically, and the measuring surfaces of P1-6~P1-9 sensors are arranged horizontally, and the shock wave of each model exceeds The arrangement of pressure measurement points is the same. The shock wave overpressure sensors at heights of 1.2m, 5.0m, and 6.0m from the ground are arranged and installed at the height of the test model.

Anti-explosion test of steel plate and reinforced concrete anti-explosion chamber of combined fireworks automatic production line

Several anti-knock tests were carried out in the manner of gradually increasing the test dose in accordance with the above table, and the structure of the anti-knock compartment was stable without any damage such as perforation, deformation and tearing.

The design and installation of the anti-explosion chamber used for the test are consistent with the technological process of the combined fireworks automatic production line, which is in line with the purpose of verifying the anti-explosion performance of the anti-explosion chamber.

The test drugs all use the explosives, propellants and bright beads used for fireworks and firecrackers. The test doses are all larger than the maximum dose of the production line, which truly and effectively simulates the impact and pressure relief of the anti-explosion chamber when the production line explodes.

Both the steel plate and the reinforced concrete anti-explosion room adopt the top pressure relief method. The test shows that the shock wave overpressure and impulse distribution around the anti-explosion room are small when the explosion occurs, which can avoid the occurrence of consecutive explosions caused by the left and right adjacent equipment and affect the pressure relief. The mouth is sealed with light and fragile material to avoid secondary damage to the surrounding building environment.

The working principle of the present invention is as follows: an internal explosion test is carried out through the anti-explosion chamber of the steel plate structure and the anti-explosion chamber of the concrete structure through which the pressure is released at the top, and the anti-explosion performance is verified through the measurement result strain and macroscopic observation; Shock wave overpressure and impulse distribution, measure the ground shock acceleration generated by the explosion, and analyze the shock wave overpressure and the damage to nearby personnel.

After the above technical scheme is adopted, the beneficial effects of the present invention are as follows: it adopts the explosion venting to the sky, the structure is reasonable, the explosion venting performance and safety performance are improved, the adjacent equipment will not be killed in a series of explosions, and the surrounding construction environment and personnel will be avoided. secondary damage.

The above is only used to illustrate the technical solution of the present invention and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be Included within the scope of the claims of the present invention.
