Description

Technical Field

[0001] The present invention belongs to the technical field of explosion - proof containers, and particularly relates to a lightweight large - scale explosion - proof container. Background Art

[0002] An explosion - proof container is a special device specifically used for transporting and storing dangerous goods such as detonators and explosives, and must have strong explosion - proof performance. With the development of the market, explosion - proof containers are becoming more and more large - scale, and large explosion - proof containers have higher requirements for explosion - proof performance. In order to meet the requirements of explosion - proof performance, the container walls of existing large explosion - proof containers are designed to be relatively thick. However, due to their large volume, the overall weight of the explosion - proof container is very large, making processing inconvenient and also not facilitating handling.

[0003] An explosion - proof container is a special device specifically used for transporting and storing dangerous goods such as detonators and explosives, and must have strong explosion - proof performance. According to the storage capacity, explosion - proof containers can be divided into various specifications. Small explosion - proof containers have a small storage capacity and relatively low requirements for explosion - proof performance, while large explosion - proof containers can store a large amount of explosive substances and have extremely high requirements for explosion - proof performance. The explosion - proof performance of existing explosion - proof containers generally depends on the thickness of the container walls. The thicker the container walls, the stronger the explosion - proof performance of the explosion - proof container. In order to meet the requirements of explosion - proof performance, the container walls of large explosion - proof containers are designed to be relatively thick. Due to the large volume of large explosion - proof containers, the overall weight of the explosion - proof container is relatively large, making it not easy to handle. Moreover, due to the requirements for the volume and thickness of the container walls of large explosion - proof containers, the processing of large explosion - proof containers is very inconvenient. Summary of the Invention

[0004] Aiming at the drawback of the heavy weight of large explosion - proof containers in the prior art, the present invention provides a lightweight large - scale explosion - proof container, which has good explosion - proof performance and relatively light weight.

[0005] The object of the present invention is achieved by the following technical solutions: A lightweight large - scale explosion - proof container includes a container body with an inlet and an outlet, and an explosion - proof door is provided at the position of the inlet and outlet. An enhancing cylinder is sleeved outside the container body. The enhancing cylinder is formed by bending and coiling a hollow metal pipe. An opening is provided on the enhancing cylinder, and the opening of the enhancing cylinder is communicated with the inlet and outlet.

[0006] In the above - mentioned solution, the enhancing cylinder formed by bending and coiling a hollow metal pipe is sleeved outside the container body, which can improve the overall structural strength and explosion - proof performance of the present invention. Since the enhancing cylinder is formed by bending and coiling a hollow metal pipe and is a hollow structure, it is lighter in weight compared to a solid container wall structure. When processing the enhancing cylinder, a pipe bender can be used to bend and coil the metal pipe into an enhancing cylinder, which is relatively convenient to process.

[0007] Preferably, the main body part of the container body is a horizontally arranged cylindrical structure, the end part of the container body is an arc-shaped structure, the side surface and the end part of the container body are smoothly transitioned, and the inlet and outlet are arranged on one of the end parts of the container body. The container body with such a structure has good explosion-proof performance.

[0008] Preferably, the outer side walls of adjacent turns of the metal pipe that bends and coils to form the reinforcing cylinder are in mutual contact, and the two sides of the connection between adjacent turns are fixedly connected by full welding. A filling space is left between the reinforcing cylinder and the outer side wall of the container body, and a filler with sound insulation and shock absorption functions is filled in the filling space. The two sides of the connection between the outer side walls of adjacent turns of the metal pipe are fixedly connected by full welding, which can make the reinforcing cylinder have good sealing performance and good structural strength, so as to greatly improve the explosion-proof performance of the large explosion-proof container. At the same time, the setting of the filler can play a role in sound insulation and shock absorption.

[0009] Preferably, a first pressure relief hole communicating with the filling space is arranged on one side of the metal pipe facing the container body, a second pressure relief hole is opened on the side of the metal pipe facing away from the container body, the second pressure relief hole is not aligned with the first pressure relief hole, and the second pressure relief hole and the first pressure relief hole are located on different turns of the metal pipe. When an explosion occurs inside the container body, the high-pressure shock wave generated by the explosion will break through the side wall of the container body and enter the filling space between the container body and the reinforcing cylinder. Because the structural strength of the filler in the filling space is poor, the high-pressure shock wave will also break through the filler and enter the metal pipe from the first pressure relief hole, and then move along the metal pipe for a certain distance and be discharged to the outside from the second pressure relief hole, so as to achieve the function of slow pressure relief.

[0010] Preferably, a cylindrical reinforcing plate is fixedly arranged on the outer side of the end part of the container body where the inlet and outlet are not arranged, and the metal pipe gradually coils around the reinforcing plate starting from the reinforcing plate to form the reinforcing cylinder. The reinforcing plate can reinforce the end part of the container body and improve the explosion-proof performance at this position. At the same time, due to the limitation of the structure of the metal pipe itself, directly coiling the metal pipe will cause a large interval at the starting end of the metal pipe, and the interval position will affect the explosion-proof performance of the large explosion-proof container. By setting a cylindrical reinforcing plate, the possible interval can be reduced.

[0011] Preferably, an installation groove is arranged on the side surface of the reinforcing plate, one end of the metal pipe is fixed in the installation groove, and the connection between the side wall of the installation groove close to the coiling direction of the metal pipe and the outer side surface of the metal pipe is an arc surface. Directly arranging the metal pipe around the reinforcing plate will also form a large gap between the metal pipe and the reinforcing plate at the position where the metal pipe coils into the first turn. When the gap is large, it will affect the explosion-proof performance of the large explosion-proof container. By setting the installation groove, the possible gap can be reduced and the explosion-proof performance can be improved.

[0012] Preferably, a connecting ring with an annular structure is fixedly connected to the container body at the inlet and outlet positions. The connecting ring is sleeved in the opening of the reinforcing cylinder. One end of the metal pipe facing the inlet and outlet is arranged around the connecting ring and fixedly connected to the outer side surface of the connecting ring. A groove is formed on the outer side of the connecting ring. The connection between the side wall of the groove facing away from the coiling direction of the metal pipe and the outer side surface of the connecting ring is an arc surface. One end of the metal pipe facing the inlet and outlet is fixedly arranged in the groove. The arrangement of the groove can also reduce the gap between the metal pipe and the connecting ring, improving the anti-explosion performance of the large anti-explosion container.

[0013] Preferably, a hinge seat is fixedly arranged on the container body above the explosion-proof door. The explosion-proof door is hinged to the hinge seat. A hydraulic buffer is further arranged between the explosion-proof door and the inner wall of the container body. Two ends of the hydraulic buffer are respectively hinged to the explosion-proof door and the inner wall of the container body. A step surface corresponding to the explosion-proof door is arranged at the inner end of the connecting ring. The arrangement of the hydraulic buffer can slow down the closing speed of the first explosion-proof door, enabling the first explosion-proof door to close slowly and improving the use safety.

[0014] Preferably, the explosion-proof door includes a door panel, and a spherical cover protruding towards the inner cavity of the container is fixedly arranged on the inner side of the door panel. The spherical cover has good structural strength and can disperse the high-pressure shock wave received more evenly, enabling the explosion-proof door to have good anti-explosion performance.

[0015] Preferably, support feet are fixedly arranged on the outer side of the container body. The arrangement of the support feet can fix the container body, enabling the cylindrical container body to be placed stably on the ground.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention has good anti-explosion performance and pressure relief effect, is relatively light in weight, convenient for transportation, and also relatively convenient for processing.
