Description

Technical Field

[0001] The invention belongs to the technical field of explosion-proof containers, and in particular relates to a capsule-shaped explosion-proof container provided with a buffer mechanism. Background Art

[0002] An explosion-proof container is a special device used to transport and store dangerous goods such as detonators and explosives, and must have strong explosion-proof performance. Most of the existing explosion-proof containers are double-layer structures, and their cylinders are relatively bulky, inconvenient to use, and the production cost is relatively high. Capsule-shaped explosion-proof containers have been widely used due to their simple structure and good explosion-proof performance. In explosion tests, it was found that the bottom of the capsule-shaped explosion-proof container is prone to bulge outward and deform under the influence of the shock wave generated by the explosion, posing certain safety hazards. There are two reasons for this. One is that the impact force received by the bottom of the single-layer container is relatively large, and the other is that after the explosion, the impurities in the container block the pressure relief hole, making it impossible to discharge the pressure in the container in time. Summary of the invention

[0003] The present invention aims at the drawbacks of the prior art that the bottom of the capsule-shaped explosion-proof container is prone to deformation, and provides a capsule-shaped explosion-proof container with a buffer mechanism. The explosion-proof container is provided with a buffer mechanism, which enhances the explosion-proof performance of the bottom of the explosion-proof container, thereby improving safety performance.

[0004] The inventive objective of the present invention is achieved through the following technical scheme: a capsule-shaped explosion-proof container provided with a buffer mechanism, comprising a tank body and a cover body matched with the tank body, the tank body is a vertical capsule-shaped structure, and the bottom of the tank body is a spherical structure, a transversely arranged bottom plate is installed in the tank body, a cavity is provided between the lower end surface of the bottom plate and the bottom of the inner cavity of the tank body, and a buffer mechanism with shock-absorbing performance is provided in the cavity.

[0005] In the above scheme, explosive items are placed on the bottom plate in the explosion-proof container. When the explosive items explode, the bottom plate and the buffer mechanism can block the shock wave and reduce the destructive force of the shock wave on the bottom of the tank body, thereby enhancing the explosion-proof performance of the bottom of the explosion-proof container and avoiding the bottom of the explosion-proof container from bulging outward and deforming when the explosive items in the inner cavity of the explosion-proof container explode.

[0006] Preferably, the lower end of the buffer mechanism is connected to the bottom of the inner cavity of the tank body, and the upper end of the buffer mechanism is connected to the bottom plate. When the bottom plate is subjected to the shock wave generated by the explosion, since the two ends of the buffer mechanism are respectively connected to the bottom of the inner cavity of the tank body and the bottom plate, the buffer mechanism can directly play a role of buffering and shock absorption on the bottom plate, thereby reducing the destructive force of the impact on the bottom of the explosion-proof container, thereby improving the explosion-proof performance of the bottom of the explosion-proof container.

[0007] Preferably, the buffer mechanism is a multilayer structure formed by winding metal plates, and gaps are left between adjacent layers of the buffer mechanism formed by winding metal plates. When the bottom plate is impacted by the shock wave, the bottom plate will impact the buffer mechanism so that the metal plate of the buffer mechanism will deform toward the gap, thereby achieving good shock absorption and buffering performance, and can significantly reduce the destructive force of the shock wave on the bottom of the explosion-proof container. At the same time, the buffer mechanism of this structure is simple in structure and less difficult to produce. Metals of different materials and thicknesses can be selected according to different explosion-proof strengths. The metal plate is not easy to produce smoke in the flames generated by the explosion, and the fragments formed after the explosion are large, and no excessive particles or powders will be generated. Existing explosion-proof containers generally have a pressure relief port on the cover body. The buffer mechanism made of rolled metal plates can prevent the pressure relief port from being blocked by particles or powders, resulting in the inability to relieve pressure.

[0008] Preferably, the gap widths between each layer of the buffer mechanism are equal. The equal gap widths enable the buffer mechanism to provide a relatively uniform buffering and shock absorbing effect on the bottom plate.

[0009] Preferably, a limit card for controlling the width of the gap between each layer of the buffer mechanism is provided between each layer of the buffer mechanism. The setting of the limit card can select limit cards of different sizes according to actual needs to adjust the width of the gap between each layer of the buffer mechanism, and the limit card installed in the buffer mechanism can also play a certain buffering role on the bottom plate.

[0010] Preferably, the limit card is a V-shaped structure, and the opening of the limit card of the V-shaped structure is arranged toward the center of the buffer mechanism, the two ends of the opening of the limit card are close to the inner wall of the gap, and the other end of the limit card is close to the outer wall of the gap, and the buffer mechanism is provided with a wire or a clamp outside to tighten the buffer mechanism. The limit card of the V-shaped structure is simple in structure, and a metal plate can be bent into a V-shaped structure by a bending machine, which is very convenient.

[0011] Preferably, the limit cards in the buffer mechanism are divided into at least three groups, each group of limit cards is distributed in a straight line, and the straight line where each group of limit cards is located is set to point to the center of the buffer mechanism, and the straight line where each group of limit cards is located is distributed in a circular array with the center position of the buffer mechanism as the center. This arrangement allows adjacent limit cards in the same group to support each other through the metal plate of the buffer mechanism, and the buffer mechanism can be better tightened and fixed by using iron wire or a clamp, and this arrangement can also make the limit cards more evenly distributed, playing a good buffering and shock absorbing role.

[0012] Preferably, the buffer mechanism is made of rubber, which has a good shock absorbing effect.

[0013] Preferably, the can body comprises a can body, a can bottom and a neck, the can body and the neck are both annular structures, the can bottom is a spherical structure, the upper end of the can body gradually converges inward and is fixedly connected to the neck, and the neck and the cover body are snap-fitted or threadedly connected.

[0014] Preferably, a support frame is fixedly connected to the lower end of the tank body for supporting the tank body and enabling the tank body to be placed vertically.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the present invention has good explosion-proof and shock-absorbing effects, can significantly improve the explosion-proof performance of the bottom of the explosion-proof container, and when an explosion occurs in the explosion-proof container, the bottom of the explosion-proof container is not easy to bulge outward and deform.

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0021] Example 1

A transversely arranged bottom plate 3 is installed in the tank body 1, and a cavity 4 is provided between the lower end surface of the bottom plate 3 and the bottom of the inner cavity of the tank body 1. A buffer mechanism 5 with shock-absorbing performance is provided in the cavity 4; a support frame 6 for supporting the tank body 1 and enabling the tank body 1 to be placed vertically is fixedly connected at the lower end of the tank body 1. The lower end of the buffer mechanism 5 is connected to the bottom of the inner cavity of the tank body 1, and the upper end of the buffer mechanism 5 is connected to the bottom plate 3. The buffer mechanism 5 is a multi-layer structure formed by winding a metal plate, and a gap 7 is left between adjacent layers of the buffer mechanism 5. The width of the gap 7 between each layer of the buffer mechanism 5 is equal. A plurality of limit cards 8 for controlling the width of the gap 7 between each layer of the buffer mechanism 5 are arranged between each layer of the buffer mechanism 5. The limit cards 8 are V-shaped structures, and the opening of the limit cards 8 of the V-shaped structure is arranged toward the center of the buffer mechanism 5. The two ends of the opening of the limit cards 8 are close to the inner wall of the gap 7, and the other end of the limit cards 8 is close to the outer wall of the gap 7. The limit cards 8 in the buffer mechanism 5 are divided into four groups, and each group of limit cards 8 is distributed in a straight line, and the straight line where each group of limit cards 8 is located points to the center of the buffer mechanism 5, and the straight lines where the four groups of limit cards 8 are located are distributed in a circular array with the center position of the buffer mechanism 5 as the center, and the four groups of limit cards 8 form a "cross" structure.

[0023] The buffer mechanism 5 is provided with a wire or a clamp outside to tighten the buffer mechanism 5.
