Description

Technical Field

[0001] This utility model relates to the field of explosion-proof equipment technology, and in particular to an explosion-proof device for acetylene cylinders. Background Technology

[0002] Acetylene (C2H2), as a basic chemical raw material, is widely used in industrial fields such as metal welding and cutting because it can produce a high-temperature flame exceeding 3000°C when burned. It is also an important raw material for organic synthesis.

[0003] Currently, acetylene cylinders are widely used in industry for storing and transporting acetylene. Because acetylene molecules are unstable, especially under high pressure, they have a strong explosive tendency. Therefore, acetylene cylinders are usually filled with porous materials (such as diatomaceous earth) and impregnated with solvents such as acetone to stabilize the acetylene gas through dissolution. However, existing acetylene cylinders still face significant safety risks in practical use, especially in operations requiring continuous gas output such as welding and cutting. The most prominent problem is "backfire," which occurs when improper operation or equipment malfunction causes a flame to propagate backward along the gas pipeline, potentially entering the cylinder. Once backfire occurs, it can easily ignite the acetylene-acetone mixture or acetylene gas inside the cylinder, causing a sudden increase in internal pressure and triggering a violent explosion. Such an explosion not only completely destroys the cylinder itself, but the resulting shockwave and debris also pose a serious threat to surrounding personnel, equipment, and the environment. Therefore, we propose an acetylene cylinder explosion-proof device to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof device for acetylene cylinders, which aims to solve the problem that improper operation of existing acetylene cylinders can cause explosions, and the resulting impact can damage the surrounding environment and workers.

[0005] To solve the above-mentioned technical problems, this utility model provides an acetylene cylinder explosion-proof device, including a housing. A fixing mechanism is provided in the middle of the inner side of the housing. Cabinet doors are hinged to both sides of the front of the housing. Explosion-proof mechanisms are provided on both the cabinet doors and the inner side of the housing. A locking mechanism is provided on the front of the cabinet doors. The explosion-proof mechanism includes a first explosion-proof plate disposed inside the housing. A connecting rod is fixedly connected to the outer surface of the first explosion-proof plate. A second explosion-proof plate is rotatably connected to the outer surface of the connecting rod. A reinforcing rib is fixedly connected to the middle of the inner side of the first and second explosion-proof plates. An energy-absorbing groove is fixedly connected to the inner side of the first and second explosion-proof plates near the reinforcing rib. Support arms are hinged to both sides of the outer surface of the first and second explosion-proof plates. The support arms are hinged to the housing and the cabinet doors. Dampers are fixedly connected to the edges and the middle of the outer surface of the first and second explosion-proof plates. The dampers are fixedly connected to the housing and the cabinet doors.

[0006] Preferably, a limiting groove is formed in the middle of the inner bottom wall of the housing, and a silicone sleeve is fixedly connected to the inner bottom wall of the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The second explosion-proof plate of this utility model is rotatably connected to the first explosion-proof plate via a connecting rod, so that the second explosion-proof plate can work in conjunction with the cabinet door and rotate with the opening and closing of the cabinet door to facilitate the disassembly and assembly of the acetylene cylinder. The first and second explosion-proof plates can effectively absorb the explosion shock wave generated by improper operation of the acetylene cylinder. The reinforcing ribs are used to enhance the structural strength of the first and second explosion-proof plates to ensure that they will not deform or be damaged under the explosion impact. The energy-absorbing groove, through a special structural design, can absorb and dissipate the energy of the explosion shock wave, further improving the explosion-proof effect. Multiple dampers are used to further dissipate the energy of the explosion shock wave, reduce the amplitude of vibration and impact, and improve the overall stability of the equipment.

The spring provides elastic force to ensure that the clamping plate can firmly clamp the acetylene cylinder. The control rod is used to control the movement of the limiting block, thereby realizing the loosening and clamping of the clamping plate. The operation is simple and convenient, improving the flexibility of the equipment. Attached Figure Description

[0038] Preferably, the fixing plate 201 is connected to the clamping plate 203 via the fixing rod 202, ensuring that the clamping plate 203 can rotate flexibly to facilitate the assembly and disassembly of the acetylene cylinder. The clamping plate 203 clamps the acetylene cylinder with a rubber pad 204.

[0039] Preferably, a spring 206 is fixedly connected to the inner side of the card holder 205, and a limiting block 207 is fixedly connected to one end of the spring 206 and is engaged with the clamping plate 203 to fix the position of the clamping plate 203.

[0040] Preferably, the control lever 208 is used to control the movement of the limit block 207, thereby realizing the loosening and clamping of the clamping plate 203. The operation is simple and convenient, and the flexibility of the equipment is improved.

[0041] Preferably, the support rod 501 provides a stable support point, ensuring that the cam 502 can rotate flexibly. By rotating the cam 502, the cabinet door 3 can be locked and unlocked, making the operation simple and convenient.

[0042] Preferably, the locking block 504 fixes the position of the limiting ring 503 by locking, ensuring that the cabinet door 3 remains closed under the impact of an explosion, thereby improving the safety of the equipment.

[0043] Preferably, the connecting pipe 8 provides a stable connection channel to ensure that the acetylene cylinder can be safely connected to external pipelines or equipment, facilitating the use of acetylene gas. The connector 9 can be easily connected to external pipelines or equipment, improving the versatility and flexibility of the equipment.

[0044] In summary, the acetylene cylinder is placed in the limiting groove 6 within the housing 1, ensuring that the bottom of the cylinder is in close contact with the silicone sleeve 7. The acetylene cylinder is clamped by the clamping plate 203 of the fixing mechanism 2, ensuring its stable placement within the housing 1.

In the event of an explosion, the first explosion-proof plate 401 and the second explosion-proof plate 403 absorb and dissipate the energy of the explosion shock wave through the reinforcing ribs 404 and the energy-absorbing grooves 405. At the same time, the support arm 406 adapts to the positional changes of the first explosion-proof plate 401 and the second explosion-proof plate 403, and the damper 407 further dissipates energy, reducing the amplitude of vibration and impact.
