Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof of hazardous chemicals, in particular to an explosion-proof structure of a hazardous chemical container. Background Art

[0002] During the use of hazardous chemicals, leakage of hazardous chemicals due to the storage environment and errors during transportation can cause fire and explosion, which is a major hidden danger. Once a dangerous accident occurs, it will cause harm to personnel and economic losses to equipment. Therefore, in the daily storage and use process, explosion-proof devices for hazardous chemical containers are needed to reduce and prevent accidents.

[0003] Existing explosion-proof devices for hazardous chemicals are shown in patent document CN213474127U, which discloses an explosion-proof device for hazardous chemical containers. By providing multiple sets of shock-absorbing springs, when the explosion-proof device encounters an impact during transportation, the impact force causes the telescopic rod and the movable rod to move, thereby achieving a shock-absorbing protection effect.

[0004] However, this solution can only provide shock-absorbing protection for the outside of the hazardous chemical container, but it is difficult to stabilize the pressure inside the hazardous chemical container, and cannot maintain a safe storage environment for certain unstable liquid hazardous substances. When the pressure inside the hazardous chemical container increases sharply, an explosion is likely to occur, which can also cause greater harm. Therefore, there is still room for improvement.

[0005] To this end, we propose an explosion-proof structure for hazardous chemicals containers to solve the above problems. Utility Model Content

[0008] A explosion-proof structure for a hazardous chemical container comprises an explosion-proof box and a container body, wherein a limiting frame for placing the container body is provided in the explosion-proof box, a sealing cover is installed at the feed port of the container body, and the top of the sealing cover is connected to a pressure regulating platform via a plurality of support columns, a piston 1 is slidably mounted inside the sealing cover, and the piston 1 and the pressure regulating platform are connected via a spring, a stabilizer storage box is installed below the sealing cover, a feed pipe is provided below the stabilizer storage box, and a piston 2 is slidably mounted inside the feed pipe, the piston 2 is connected to the piston 1 via a connecting rod to achieve synchronous sliding of the piston 2 and the piston 1, and connecting grooves are provided inside the piston 2 and the piston 1, and the connecting grooves are composed of a transverse groove that penetrates horizontally and a vertical groove that vertically connects the transverse groove.

[0009] In a further embodiment, a plurality of transverse grooves are provided, and the plurality of transverse grooves are symmetrically distributed about the axis centerline of the vertical groove.

[0010] In a further embodiment, the stabilizer storage box adopts an annular structure, and a plurality of feed pipes are evenly distributed along the lower surface of the stabilizer storage box.

[0011] In a further embodiment, a pressure regulating plate is mounted on the top of the spring, a screw is threadedly connected to the top of the pressure regulating platform, and the screw is rotatably connected to the pressure regulating plate.

[0012] In a further embodiment, a limiting rod parallel to the screw rod is further connected to the pressure regulating plate, and the limiting rod is slidably connected to the pressure regulating platform.

[0013] In a further embodiment, a sealing sleeve is sandwiched between the sealing cover and the feed port of the container body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides movable pistons one and two, so that when the internal pressure of the container body is too large, the piston one moves up under the pushing action of the internal pressure, and the connecting groove in the piston one is connected to the external environment, thereby releasing the internal gas of the container body to achieve the effect of pressure relief. At the same time, after the piston two moves up, the stabilizer in the stabilizer storage box can flow out from the discharge pipe and contact with the hazardous chemicals in the container body, and the hazardous chemicals are neutralized to achieve the effect of stabilizing the pressure, thereby maintaining a safe storage environment for certain unstable liquid hazardous substances in the container body, thereby effectively enhancing the explosion-proof effect of the entire device.
