Description

Technical Field

[0001] The present application relates to the field of explosion relief devices, and particularly to an explosion relief panel with a lower thermal insulation structure. Background Art

[0002] An explosion relief panel, also known as an explosion-proof panel or explosion-proof and pressure relief panel, is a material designed specifically for equipment safety and is usually installed at the explosion relief opening of the target equipment. Its core function is to quickly rupture through a carefully designed weak area when an explosion occurs in the equipment, rapidly discharging the huge energy and high-pressure gas generated by the explosion, thereby greatly reducing the impact and damage to the main structure of the equipment. This mechanism not only effectively protects the equipment itself but also significantly reduces the potential risks of explosion incidents to operators and the surrounding environment. A common explosion relief panel is provided with an explosion relief sheet, and the explosion relief sheet is provided with a U-shaped tear seam. When an explosion occurs in the equipment, the explosion relief sheet can rupture along the tear seam, thereby opening the pressure relief port to achieve the pressure relief effect of the equipment.

[0003] Chinese Patent with Publication No. CN220254900U discloses an explosion relief panel and an energy storage cabinet. The explosion relief panel includes: a panel body, a thermal insulation member, a gasket, and a first sealing member. A slit is formed in the panel body. The panel body has a first side and a second side opposite to each other in the thickness direction. The thermal insulation member is disposed on the first side, and the gasket is disposed on the second side and is arranged around the periphery of the panel body and is used to block the slit on the second side. The first sealing member is disposed on the first side and is used to block the slit on the first side. Thus, by providing the first sealing member and the gasket, it further includes: a cover body and a thermal insulation member. The cover body and the thermal insulation member are disposed on the first side, and the cover body is used to accommodate the thermal insulation member. In the above related technology, the thermal insulation member is provided to insulate the explosion relief opening position, reducing the influence of the external temperature on the internal temperature of the equipment. The cover body is provided to protect the panel body, reducing the problem that the panel body is damaged in rainy, snowy, hail weather and affects the explosion relief effect.

[0004] However, in the above related technology, both the cover body and the thermal insulation member are disposed on the side of the panel body facing the outside of the equipment, and the cover body protrudes outside the energy storage cabinet, affecting the stacking and transportation of the energy storage cabinet. Utility Model Content

[0005] In order to reduce the volume of the explosion relief panel protruding from the energy storage cabinet and alleviate the problem of inconvenient stacking during the transportation of the energy storage cabinet, the present application provides an explosion relief panel with a lower thermal insulation structure.

[0017] Optionally, gaskets are provided on both sides of the explosion venting piece, the explosion venting piece presses one of the gaskets onto the target device, and the flange frame presses the other gasket onto the explosion venting piece.

[0039] The following is combined with Figure 1-8 This application is described in further detail.

[0040] The present application embodiment discloses a lower thermal insulation structure explosion relief plate. Figure 1 and Figure 2 The explosion-venting plate of the lower thermal insulation structure includes a flange frame 1 and an explosion-venting piece 11. The explosion-venting piece 11 is rectangular in the embodiment of the present application, and the flange frame 1 is annular and matches the contour of the explosion-venting piece 11.

[0041] like Figure 2 and Figure 3, the flange frame 1 presses the explosion venting disc 11 against the explosion vent 13 of the target device through the connecting member 2. In the embodiment of the present application, the target device refers to an energy storage cabinet. When the flange frame 1 is installed on the energy storage cabinet, the explosion vent 13 is located inside the flange frame 1. The connecting member 2 can be a rivet, a bolt or a clamping structure, etc. The connecting member 2 in the embodiment of the present application includes a locking bolt 21 and a blind rivet nut 22. The energy storage cabinet is provided with a circle of through holes for installing the blind rivet nut 22 on the peripheral wall of the explosion vent 13. The locking bolts 21 and the blind rivet nut 22 are in one-to-one correspondence. The locking bolt 21 sequentially passes through the flange frame 1 and the explosion venting disc 11 and is threadedly connected to the corresponding blind rivet nut 22. Under the action of the locking bolt 21, the blind rivet nut 22 is riveted to the energy storage cabinet.

[0042] As Figure 4 , gaskets 3 are provided on both the side of the explosion venting disc 11 facing the flange frame 1 and the side背离 the flange frame 1. The gasket 3 is annular and adapted to the inner contour of the flange frame 1. The explosion venting disc 11 is provided with a U-shaped tear seam 12. When an explosion occurs inside the energy storage cabinet, resulting in a sharp increase in pressure, the explosion venting disc 11 tears from the tear seam 12, thereby opening the explosion vent 13 for pressure relief.

[0043] As Figure 5 and Figure 6 , the inner rings of the two gaskets 3 both extend inward and cover the tear seam 12. Since the tear seam 12 of the common explosion venting disc 11 is formed by a plurality of long strip-shaped through holes arranged at intervals, the sealing effect of the explosion venting disc 11 itself is poor. By covering the tear seam 12 with the gasket 3, it is beneficial to improve the sealing effect of the explosion venting disc 11 on the explosion vent 13. When an explosion occurs inside the energy storage cabinet, the pressure inside the energy storage cabinet rises sharply, causing the part of the explosion venting disc 11 close to the tear seam 12 to be pulled out from between the two gaskets 3 and torn by the air pressure for pressure relief.

[0044] As Figure 4 and Figure 6, the gasket 3 far from the flange frame 1 is recorded as the first sealing sheet 31, and the gasket 3 close to the flange frame 1 is recorded as the second sealing sheet 32. The first sealing sheet 31 is provided with a first mounting hole 33 in the thickness direction corresponding to each rivet nut 22 position, the washer 23 of the rivet nut 22 is inserted into the corresponding first mounting hole 33, and the thickness of the rivet nut 22 is less than the thickness of the first sealing sheet 31. The explosion-proof plate 11 is fixedly connected with a limiting ring 35 corresponding to each rivet nut 22 position, and the limiting ring 35 can allow the locking bolt 21 to pass through. The limiting ring 35 on the explosion-proof plate 11 is arranged toward the second sealing sheet 32, and the second sealing sheet 32 ​​is provided with a second mounting hole 34 for the limiting ring 35 to pass through, and the thickness of the second sealing sheet 32 ​​is less than the second sealing sheet 32. The maximum compression of the first sealing sheet 31 is limited by the washer 23 of the rivet nut 22, and the maximum compression of the second sealing sheet 32 ​​is limited by the limiting ring 35. In the embodiment of the present application, the thickness of the gasket 23 of the rivet nut 22 is half the thickness of the first sealing sheet 31, and the thickness of the limiting ring 35 is half the thickness of the second sealing sheet 32, thereby controlling the maximum compression of the first sealing sheet 31 and the second sealing sheet 32 ​​to be 50%. Experiments have shown that when the compression of the first sealing sheet 31 and the second sealing sheet 32 ​​is 50%, the sealing effect is best.

[0045] like Figure 7 and Figure 8 , a heat preservation board 4 is arranged on the side of the explosion venting piece 11 away from the flange frame 1, and the heat preservation board 4 is located in the inner circle of the first sealing piece 31. The heat preservation board 4 can be fixedly connected to the side of the explosion venting piece 11 away from the flange frame 1 by gluing, so as to achieve a heat preservation effect. The heat preservation board 4 can also be fixedly connected to the side of the explosion venting piece 11 away from the flange frame 1 by a cover shell, and the heat preservation board 4 is located in the cover shell (not shown in the figure), and the cover shell is fixedly connected to the explosion venting piece 11 by spot welding or gluing, so that the heat preservation board 4 is pressed against the explosion venting piece 11, so as to achieve a heat preservation effect.

[0046] In the embodiment of the present application, a plurality of guide posts 41 are vertically fixedly connected to the side of the explosion venting plate 11 facing the insulation plate 4, and the guide posts 41 are fixedly connected to the explosion venting plate 11 by spot welding to avoid the problem that the perforation of the explosion venting plate 11 affects its sealing. Each guide post 41 passes through the insulation plate 4, and a limit plate 42 is provided at one end of the guide post 41 passing through the insulation plate 4, and the limit plate 42 is used to limit the insulation plate 4 on the explosion venting plate 11. The limit plate 42 is sleeved on the guide post 41, and the end of the guide post 41 away from the explosion venting plate 11 is threadedly connected to the limit bolt 43, and the limit bolt 43 is used to limit the limit plate 42 on the guide post 41, so that the insulation plate 4 can be detachably installed on the explosion venting plate 11.

[0047] like Figure 1 and Figure 2, a protective plate 5 for covering the explosion-venting plate 11 is provided on the side of the flange frame 1 away from the explosion-venting plate 11. The protective plate 5 is rectangular, and one side of the protective plate 5 is fixedly connected to the flange frame 1 by a locking bolt 21. When the explosion-venting plate 11 explodes and flips, the protective plate 5 can also flip outward under the action of pressure, so that the explosion-venting port 13 is opened. Each side of the protective plate 5 extends to the side of the flange frame 1 away from the explosion-venting plate 11, and the side of the explosion-venting plate 11 facing the protective plate 5 is fixedly connected with a sealing gasket 51. The sealing gasket 51 can be fixedly connected to the explosion-venting plate 11 by gluing, and the sealing gasket 51 can support the protective plate 5. The sealing gasket 51 is an elastic gasket. The sealing gasket 51 is arranged between the explosion-venting plate 11 and the protective plate 5 to play a waterproof role. In addition, the sealing gasket 51 has a certain support and buffering effect on the protective plate 5. When the protective plate 5 is subjected to external forces, the sealing gasket 51 is used for buffering, thereby reducing the problem of failure caused by deformation of the explosion-venting plate 11.

[0048] The implementation principle of the embodiment of the present application is: the insulation board 4 is arranged on the side of the explosion-proof plate 11 facing the inside of the energy storage cabinet, so as to reduce the situation that the insulation board 4 extends out of the explosion-proof opening 13, thereby reducing the volume of the explosion-proof plate protruding outside the energy storage cabinet, making the surface of the energy storage cabinet smooth, thereby facilitating the stacking operation during the transportation of the energy storage cabinet, which is beneficial to improving the transportation efficiency and reducing the problem that the explosion-proof plate is easily bumped during transportation.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
