Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof containers, in particular to an explosion-proof container tank. Background Art

[0002] Various flammable and explosive items, especially civilian blasting equipment, require explosion-proof containers during transportation and storage. In particular, when explosives and detonators are transported in the same vehicle, the detonators are placed in explosion-proof containers to separate the explosives from the detonators to prevent the explosion of the detonators from detonating the explosives.

[0003] Most of the existing explosion-proof containers are composed of a cylinder and a sealing cover, and an explosion venting hole is provided on the sealing cover. However, the existing explosion-proof containers still have the following deficiencies during use:

[0004] 1. In the existing explosion-proof container tank, except for the detachable sealing cover, the other tank parts are mostly integrated structures. During the use of the explosion-proof container tank, if the explosion-proof container tank is partially damaged, the entire tank body needs to be replaced, resulting in a waste of resources;

[0005] 2. The existing explosion vents are all set on the sealing cover. When the flame and air pressure generated after the explosion are directly discharged through the explosion vent, large sparks and noise will be generated, which poses certain safety hazards;

[0006] Therefore, a kind of explosion-proof container tank that can overcome above-mentioned disadvantages is badly needed. Utility Model Content

[0012] Furthermore, an outer folding edge is provided on the outer wall of the external threaded barrel along the circumference of the external threaded barrel.

[0013] Furthermore, an upper cover and a lower head matched with the lower end opening of the internally threaded tube are arranged in the lower end opening of the internally threaded tube, and a first explosion relief hole is also arranged on the upper cover and the lower head, and the first explosion relief hole on the elliptical upper head is staggered.

[0014] Furthermore, the handwheel includes several support tubes and an annular tube, both of which are hollow structures.
