A high-safety horizontal explosion-proof tank door and horizontal explosion-proof tank

Abstract

The high-security horizontal explosion-proof tank door body and horizontal explosion-proof tank described in the present invention have a door panel that is a multi-section flat plate structure including a plurality of left-leaning plates and right-leaning plates. Whether it is a vertical plate or an annular plate, when the explosive in the explosion-proof tank explodes, the high-pressure gas will generate an explosion impact force on the explosion-proof tank door body. The explosion impact force on the explosion-proof tank door body acts on the left-leaning plate and the right-leaning plate respectively, and will generate horizontal components or radial components in opposite directions along the horizontal direction or radial direction. The horizontal components or radial components generated by the left-leaning plate and the right-leaning plate can balance each other, and can even generate horizontal components or radial components that keep the two door leaves closed at all times during the explosion impact, further improving the explosion-proof tank's ability to withstand shock waves from a structural perspective, thereby improving the safety of the door body.

Description

Technical Field

[0001] The invention relates to a high-safety horizontal explosion-proof tank door body and a horizontal explosion-proof tank, belonging to the technical field of safety explosion-proof equipment. Background Art

[0002] Explosion-proof tanks are explosion-proof equipment used for temporary storage and transfer of suspected explosives. During the transfer and temporary storage of suspected explosives, if the suspected explosive explodes, the shock wave generated at the moment of the explosion can reduce the lethal effect on the surrounding environment and surrounding personnel. It is an essential equipment for explosion-proof safety inspection departments such as public security, armed police, civil aviation, railways, ports, customs, and competition venues.

[0003] Existing explosion-proof tanks are divided into open explosion-proof tanks and closed explosion-proof tanks; currently, the open explosion-proof tanks are more widely used. Since the suspected explosives will inevitably cause great damage to the surrounding environment after the explosion, and may even cause secondary damage to the surrounding personnel, the scope of use of the open explosion-proof tanks is greatly limited and is only suitable for outdoor open areas. Existing closed explosion-proof tanks are divided into two types: vertical explosion-proof tanks and horizontal explosion-proof tanks, both of which include a tank body and a door body. In the utility model patent with application number 201920495060.5, the tank body structure is a multi-layer sandwich structure with an interlayer weak explosion buffer material, which can control the fragments generated by the explosion in the tank body and effectively weaken the leakage of the shock wave. However, due to the unreasonable structural design of the door body, its explosion-proof function is very limited, and it may even be blown away because it cannot withstand the impact of the shock wave generated by the explosion of the explosive in the tank body, which poses a great safety hazard. Moreover, the tank cover of the existing closed explosion-proof tank cannot effectively achieve the sealing effect of the high-pressure gas generated by the explosion. The existing explosion-proof tank door takes a long time to open and close, and is not easy to open and close accurately, which is not conducive to the rapid evacuation of the explosion-proof personnel during the explosion-proof process. Summary of the invention

[0004] In order to make up for the deficiencies in the above-mentioned field, the present invention provides a high-safety horizontal explosion-proof tank door body and a horizontal explosion-proof tank, which significantly improve the explosion-proof tank door body's ability to withstand explosion impact force, provide multiple guarantees for the axial load-bearing of the explosion-proof tank, have high safety, and the explosion-proof tank door body is easy to open and close, and can effectively realize the sealing function of the high-pressure gas generated by the explosion.

[0021] The advantages of the present invention over the prior art are:

[0022] 1. The high-security horizontal explosion-proof tank door body described in the present invention has a multi-stage flat plate structure including a plurality of left-leaning plates and right-leaning plates. Whether it is a vertical plate or an annular plate, when the explosive in the explosion-proof tank explodes, the high-pressure gas will generate an explosion impact force on the explosion-proof tank door body. The explosion impact force on the explosion-proof tank door body acts on the left-leaning plate and the right-leaning plate respectively, and will generate horizontal or radial components of force in opposite directions along the horizontal direction or radial direction. The horizontal or radial components of force generated by the left-leaning plate and the right-leaning plate can balance each other, and can even generate horizontal or radial components of force that keep the two door leaves closed at all times during the explosion impact, further improving the explosion-proof tank's ability to withstand shock waves from a structural perspective, thereby improving the safety of the door body.

[0023] 2. The high-safety horizontal explosion-proof tank door body described in the present invention has a tooth-embedded structure of two door leaves that are inlaid with each other to form a tooth-embedded nested structure to achieve a mosaic connection between the door leaves, which can effectively withstand the explosion shock wave generated by the explosion of the explosive in the explosion-proof tank on the explosion-proof tank door body, and the tooth tops of the teeth protrude from the middle side of the door panel, and the groove bottoms of the tooth grooves protrude from the middle side of the door panel, which can effectively withstand the explosion shock wave generated by the explosion of the explosive in the explosion-proof tank on the explosion-proof tank door body; and the tooth-embedded nested structure formed by the column-type tooth-embedded structure on the axial section of the explosion-proof tank has the structural characteristics and functions of a labyrinth seal, which can effectively seal the high-pressure gas generated by the explosion of the explosive in the explosion-proof tank and achieve decompression and explosion relief of the high-pressure gas in the tank.

[0024] 3. The high-safety horizontal explosion-proof tank door body described in the present invention adopts a nested connection between the enclosure plate and the tank mouth, which further enhances the explosion-proof tank door body's ability to withstand the impact of explosions, provides multiple guarantees for the force of the door body, and can also make the door body of the explosion-proof tank have the same explosion-proof performance as the tank body. The tank body and the door body of the explosion-proof tank form a sealed overall structure, coupled with the column-type tooth-embedded structure between the door leaves, and the multi-section flat plate or annular plate structure of the door plate, so that the door body and the tank body can withstand and absorb greater and more shock waves at the moment of explosion than the existing explosion-proof tanks of the same specification, thereby achieving effective and safe explosion-proofing indoors; and the enclosure plate encloses the outside of the tank mouth, which is easy to achieve the docking and opening and closing of the door leaves.

[0025] 4. The high-safety horizontal explosion-proof tank door body described in the present invention has a door panel and a tooth-embedded structure located axially in front of the plane where the tank mouth of the explosion-proof tank body is located, and its enclosing plate is enclosed outside the tank mouth, which makes it easy to realize the external rotation docking opening and closing, left and right translation opening and closing, and radial translation docking opening and closing of the door leaf.

[0028] 7.

[0029] 8. The high-safety horizontal explosion-proof tank of the present invention comprises an inner tank composed of a composite material interlayer and an energy-absorbing buffer material and an outer tank with a plurality of explosion-relief holes arranged at the upper and lower positions of the tank wall. The inner tank can effectively absorb the shock wave generated by the explosion, so that the shock wave energy reaching the explosion-relief holes is reduced to 20%, so that the outer tank and the door body do not produce any deformation, and the outer tank and the door body can be reused. Not only the tank body's ability to withstand explosives is improved, but also the service life of the outer tank is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] Example 1

[0053] like Figure 1-3As shown, it is a structural schematic diagram of a first embodiment of a high-security explosion-proof tank door body of the present invention, the high-security explosion-proof tank door body 1 comprises a left door leaf 11 and a right door leaf 12 which are interlocked with each other; the left door plate 111 and the right door plate 121 are symmetrically arranged with the position where the middle side faces of the left door plate 111 and the right door plate 121 as the axis; the left door plate 11 comprises a plurality of straight plates connected end to end from left to right, and the right door plate comprises a plurality of vertical plates connected end to end from right to left; wherein in the axial direction of the explosion-proof tank, the plate whose left edge is located behind its right edge is a right-leaning plate, and the plate whose left edge is located in front of its right edge is a left-leaning plate, the sum of the effective areas of all the left-leaning plates of the left door plate is less than or equal to the sum of the effective areas of all the right-leaning plates, and the sum of the effective areas of all the right-leaning plates of the right door plate is greater than or equal to the sum of the effective areas of all the left-leaning plates; the effective area mentioned here refers to the inner area of ​​the tank mouth extending to the door plate along its axial direction after the door body is closed, or the door plate area directly subjected to the explosion shock wave when the explosive explodes.

[0054] As a preferred solution, Figure 1-3 As shown, the left door panel 11 includes, from left to right, a first vertical plate 1111, a second vertical plate 1112 and a third vertical plate 1113 connected end to end; the first vertical plate 1111 is a right-leaning plate, the second vertical plate 1112 is perpendicular to the axis of the explosion-proof tank, and the third vertical plate 1113 is a left-leaning plate; the plane where the left edge of the first vertical plate 111 and the right edge of the third vertical plate 113 are located is perpendicular to the axis of the explosion-proof tank.

[0055] The high-security horizontal explosion-proof tank door body described in the present invention has a door panel that is a multi-section flat plate structure including a plurality of left-leaning panels and right-leaning panels. When the explosive in the explosion-proof tank explodes, an axial impact force will be generated on the explosion-proof tank door body along the axis direction of the explosion-proof tank. The axial impact force on the explosion-proof tank door body acts on the left-leaning panel and the right-leaning panel, and will generate horizontal force components or radial force components with opposite directions along the horizontal direction. Since the horizontal force components or radial force components generated by the left-leaning panel and the right-leaning panel can balance each other, or even generate horizontal force components or radial force components that keep the two door leaves closed at all times during the explosion impact, the explosion-proof tank's ability to withstand shock waves is further improved from a structural perspective, thereby improving the safety of the door body. Preferably, the high-security horizontal explosion-proof tank door body described in the present invention can also be used for vertical explosion-proof tanks.

[0056] The left door leaf 11 and the right door leaf 12 each include a door panel 111 and a tooth-embedded structure 112 provided on the door panel. The left door leaf 11 and the right door leaf 12 are arranged relative to each other through their respective tooth-embedded structures to achieve mutual engagement of the left door leaf 11 and the right door leaf 12. The tooth-embedded structure 112 is provided at the contact position between the door panels; the surface with the same vertical distance between the contacting vertical surfaces of the left door panel 111 and the right door panel 121 is the middle side surface 11131; the tooth-embedded structure 112 comprises at least several teeth 1121 and tooth grooves 1122 provided in pairs on the left door panel 111 and the right door panel 121; the teeth 1121 are vertically provided on a main board surface of the door panel 111 and the top of the teeth 1121 protrudes from the middle of the door panel 111 in the horizontal direction. On the middle side surface, the tooth groove 1122 is vertically arranged on the other main board surface 111 of the door panel and the notch of the tooth groove 1122 is flush with the middle side surface of the door panel 111 in the horizontal direction; the teeth 1121 and the tooth groove 1122 are distributed at intervals on the edges of the front and rear main board surfaces of the door panel close to the middle side surface in the horizontal direction; the teeth 1121 and the tooth groove 1122 of the left door leaf 11 can cooperate with the tooth groove and teeth of the adjacent right door leaf 12 and the two can be embedded in each other. The high-safety horizontal explosion-proof tank door body 1 of the present invention, the left door leaf 11 and the right door leaf 12 cooperate with each other through their respective tooth-embedded structures to form a tooth-embedded nesting structure to achieve the embedding of the two, which can effectively withstand the axial shock wave generated by the explosion in the explosion-proof tank to the explosion-proof tank door body 1, and the tooth top of the tooth-embedded plate 1121 protrudes from the inner edge of the door plate 111, and the notch of the tooth-embedded groove 1122 is flush with the inner edge of the door plate 111, such as Figure 3 As shown, the nesting route of the tooth-embedded nested structure formed in this way is similar to a maze, realizing a labyrinth-type seal, which can withstand a larger axial explosion impact force, and when the tooth-embedded structure covers the contact parts of the door panels, it can also effectively seal the high-pressure shock wave and high-pressure gas generated by the explosion in the explosion-proof tank to prevent them from escaping directly.

[0057] Preferably, the door leaf 11 also includes an enclosure plate 113 for tightly enclosing the mouth of the explosion-proof tank and extending along the axial direction of the explosion-proof tank. The enclosure plate 113 is arranged on the outer side surface of the door panel 111, and its front end is connected to the door panel 111. The inner side of the rear end of the enclosure plate 113 is provided with an enclosure tooth embedding structure 1131 for tightly embedding with the tank mouth tooth embedding structure 211 of the explosion-proof tank body. The enclosure tooth embedding structure 1131 is embedded with the tank mouth tooth embedding structure 211 arranged on the outer edge of the explosion-proof tank mouth, and the enclosure tooth embedding structure 1131 includes teeth and tooth grooves spaced apart in the axial direction of the explosion-proof tank. The ability of the explosion-proof tank door body 1 to withstand axial shock waves is further enhanced, multiple safeguards are provided for the force of the door body 1, and the door body 1 of the explosion-proof tank can have the same explosion-proof performance as the tank body 2. The tank body 1 and the door body 2 of the explosion-proof tank form a sealed overall structure, which can achieve effective and safe explosion-proofing indoors; and the enclosure plate 113 is enclosed on the outside of the tank mouth, which makes it easy to realize the external rotation docking opening and closing, left and right translation docking opening and closing, and radial translation docking opening and closing of the door leaf 11.

[0058] Preferably, the door leaves may be of the same or different sizes and / or shapes.

[0059] Preferably, the enclosing tooth embedding structure 1131 includes vertical trapezoidal teeth and vertical trapezoidal grooves spaced apart in the axial direction of the explosion-proof tank.

[0061] Preferably, the plane where the enclosure plate 113 and the door plate 111 meet is higher than the plane where the mouth of the explosion-proof tank is located, and the door plate and the tooth structure are axially located in front of the plane where the mouth of the explosion-proof tank body 2 is located.

[0062] Example 2

[0063] When the explosive in the explosion-proof tank explodes, a circumferential impact force will be generated on the explosion-proof tank door body 1 along the axial direction of the explosion-proof tank. The high-safety explosion-proof tank door body 1 of the present invention, such as Figure 4The figure shows the schematic diagram of the main structure of the second embodiment of the explosion-proof tank door body 1 of the present invention. The difference from the embodiment is that, taking the left door plate as an example, the left door plate 111 is a three-stage flat plate structure including a first annular plate 1111', a second annular plate 1112' and a third annular plate 1113' arranged along its radial direction. When the impact force of the explosion-proof tank door body 1 acts on the first annular plate 1111' and the third annular plate 1113', radial components of force with opposite directions will be generated along the horizontal direction. The effective area of ​​the first annular plate 1111' is less than or equal to the effective area of ​​the third annular plate 1113'. When the effective areas of the two are equal, the horizontal component or radial component of force generated can be balanced with each other. When the effective area of ​​the first annular plate 1111' is less than the effective area of ​​the third annular plate 1113', a horizontal component or radial component of force can be generated to keep the two door leaves closed at the time of explosion impact, which further enhances the explosion-proof tank door body 1's ability to withstand impact force; and provides multiple guarantees for the explosion-proof tank, greatly improving the safety performance of the explosion-proof tank.

Preferably, the reinforcing rib plate 143 provided under each door leaf is a double rib plate structure provided front and rear along the axial direction of the explosion-proof tank. Compared with a single-opening door, this solution reduces the opening and closing stroke of the explosion-proof tank door by half, reduces the opening and closing time of the explosion-proof tank door, and improves the survival rate for the operator.
