Description

Technical Field

[0001] This utility model relates to the field of explosion-proof panels, and in particular to explosion-proof panels with heat insulation materials and their storage structures. Background Technology

[0002] Explosion-proof plates protect silos, hoppers, storage chambers, pressure vessels, filtration systems, bucket elevators, and other unconfined enclosures or material processing machines. These enclosures or machines store powdered products or gases, which, under certain conditions, can cause internal pressure and temperature rise, potentially leading to an explosion. If abnormal overpressure occurs inside the enclosure, the explosion-proof plate will tear in the embrittlement zone, forming a hole through which pressurized gas can escape.

[0003] An explosion-proof plate typically comprises a fracture-resistant metal plate with a brittle zone near its outer edge. A frame is mounted on and around the fracture-resistant metal plate to secure it. At least one sealing strip is fitted below and around the fracture-resistant metal plate to cover the brittle zone. An interface seal is also typically present between the top frame and the fracture-resistant metal plate. The explosion-proof plate is bolted around the opening in the housing to be protected, with the bolts matching the mounting holes near the brittle zone around the perimeter of the explosion-proof plate.

[0004] In addition, for certain types of use, such as energy storage systems (ESS) that require outdoor installation in containers, it is best to add heat insulation panels on top of the explosion-proof panels.

[0005] ESS (Energy Storage and Energy) containers contain batteries that store electrical energy, typically derived from renewable energy generation systems such as solar panels or wind turbines; these batteries are used to power local or temporary power grids. The batteries within the container pose a risk of gas emissions and thermal runaway. Thermal runaway can lead to the accumulation of large amounts of flammable gas, potentially causing an explosion if the container is then closed. Therefore, explosion-proof panels are an effective solution to minimize the explosion hazard.

[0006] However, since the container is outdoors, the explosion-proof panel is in contact with the external environment through one side of the container. Depending on the climate, a large temperature difference between the inside and outside of the container may cause condensation on the explosion-proof panel and inside the container. This condensation must be absolutely avoided to prevent corrosion of the equipment. Corrosion can lead to electrical insulation failure, battery overheating and subsequent runaway, and may even cause short circuits and fires.

[0007] The "explosion-proof panel" referred to here is an explosion-proof panel with thermal insulation material. The fractured fragment within its embrittlement zone is covered by an aluminum insulated box, which contains the thermal insulation material. The insulated box is an assembly attached to the top of the fractured fragment. The insulated box is constructed by first creating a box body, then adding the thermal insulation material inside. The insulated box has a base made of a metal sheet, and the outer sidewalls are formed by cutting off the four corners of the sheet and folding each side. The corners are then fixed to ensure a tight seal. The assembly of the angle iron and the box sidewalls is further reinforced with rivets. To secure the insulated box to the fractured fragment of the explosion-proof panel, the sidewalls have protruding corners on opposite sides at the bottom, allowing them to be fixed to the fragment with rivets. Sealant is applied around the sidewalls and the fractured fragment.

[0008] However, the design of this insulated enclosure and its connection to the explosion-proof panel has a major flaw. In fact, the enclosure is susceptible to climatic conditions; over time, the sealed area corrodes, weakening the sealant and allowing water to seep into the enclosure. Water saturation increases the enclosure's weight, thus increasing the load on the break-through plates and altering the original effectiveness of the explosion-proof panel. Initially, the break-through plates can easily and quickly break, opening the entire enclosure. Furthermore, the manufacturing and securing principle of the enclosure has another drawback: it requires numerous steps. Utility Model Content

[0009] The purpose of this invention is to provide an explosion-proof plate with thermal insulation properties. This explosion-proof plate not only does not have the above-mentioned disadvantages, but also meets safety requirements, will not lose its sealing properties over time, and is simpler to manufacture.

[0010] The technical solution adopted by this utility model to solve its technical problem is:

[0011] Explosion-proof panels include:

[0012] The fracture element includes an embrittlement zone (capable of fracturing under overpressure inside a structure with an explosion-proof plate) and a peripheral shoulder.

[0013] A fastening frame, mounted on the outer peripheral shoulder, may not cover the embrittlement zone (the fastening frame is mounted outside the inner section defined by the embrittlement zone so that the fracture element is not obstructed when it opens), or it may cover an area of ​​a few millimeters of the embrittlement zone.

[0014] Ideally, a sandwich material interface seal should be installed between the outer shoulder and the fastening frame, covering the brittle area.

[0015] The thermal insulation material connected to the fracture element,

[0016] The explosion-proof plate has the following features:

[0017] The fracture element has a full, continuous, three-dimensional monolithic surface manufactured as a single structure to form a shell. The shell includes a main surface, an outer peripheral wall that is continuous and closed along its entire circumference (the wall surrounds the entire perimeter of the main surface and has closed corners), and an outer peripheral shoulder that protrudes outward from the shell and is opposite to the main surface and in contact with the outer peripheral wall. This outer peripheral shoulder forms the outer fixing surface of the fracture element. The shell provides an internal space (the sidewalls of which are continuously closed) in which thermal insulation material is placed.

[0018] Therefore, the fracture element of the explosion-proof panel, through its three-dimensional integrally molded shell, achieves a component that combines two functions: explosion-proof panel fracture and explosion-proof panel thermal insulation. Because the shell is manufactured as a single piece, it ensures perfect sealing. In fact, the three-dimensional shape of the shell is manufactured as a whole, from a single piece of material, maintaining the continuity of the full and closed surface throughout the three-dimensional molding process. That is, the connection between the main surface and the outer peripheral wall is full and continuous, the perimeter of the outer peripheral wall is also solid and continuous, and the connection between the outer peripheral wall and the outer shoulder is also solid and continuous. Therefore, the sealing performance of the fracture element, which integrates thermal insulation material, is perfectly achieved. In particular, the fracture element with integrated thermal insulation material can be installed on the outside of the structure requiring protection without any risk of water leakage due to severe weather.

[0019] Explosion-proof panels, including:

[0020] A fracture element, comprising an embrittled region and a peripheral shoulder,

[0021] A fastening frame, the fastening frame is mounted on the outer peripheral shoulder,

[0022] Thermal insulation material connected to the fractured component,

[0023] The fracture element has a monolithically manufactured, continuous, three-dimensional, one-piece molded surface that forms a shell. The shell includes a main surface and an outer peripheral wall that is in contact with the main surface. The outer peripheral wall is continuous and closed along its entire circumference. An outer peripheral shoulder is opposite to the main surface and in contact with the outer peripheral wall and protrudes outward. The outer peripheral shoulder constitutes the outer peripheral surface of the fracture element. The shell provides an internal space in which thermal insulation material is installed.

[0024] In one embodiment, a support seal is also included, disposed below the outer peripheral shoulder, abutting against the lower surface of the outer peripheral shoulder, and opposite the mounting surface of the fastening frame.

[0025] In one embodiment, the explosion-proof plate includes a rigid plate that presses against the thermal insulation material facing the main surface of the housing. The rigid plate is fixed to a fixing plate and is integrally connected to the inner side of the housing.

[0026] In one embodiment, the storage structure includes at least one explosion-proof plate and includes a silo, hopper, storage chamber, agitator, filtration system, pipeline, bucket elevator or ESS container.

[0027] In one embodiment, the outer peripheral wall is substantially perpendicular to the main surface and the outer peripheral shoulder is perpendicular to the outer peripheral shoulder.

[0028] In one embodiment, the housing (fracture element) is manufactured by stamping. Preferably, the fracture element is formed by stamping a three-dimensional monolithic metal sheet.

[0029] In one embodiment, the height of the outer peripheral wall is between 20 and 100 mm, preferably around 40 mm. The thermal insulation material is preferably disposed within the housing and does not extend beyond the plane of the outer peripheral shoulder.

[0030] In one embodiment, the insulation material fills the entire interior of the shell, adhering tightly to both the interior of the main surface and the interior of the outer peripheral walls. For example, the insulation material is rock wool, which has been cut to a shape perfectly matching the internal container of the shell. Alternatively, the insulation material can be an insulation board with a cross-sectional area identical to that of the main surface, adhered tightly to the inside of the main surface. Preferably, the insulation material is bonded to the inside of the main surface.

[0031] In one embodiment, the outer peripheral shoulder includes a plurality of fixing holes and a fastening limiting device is provided around the fixing holes.

[0032] In one embodiment, the interface seal is frame-type and may also be divided into several parts, corresponding to the side of the explosion-proof plate, and connected in a concave-convex form to achieve surface continuity.

[0033] In one embodiment, the explosion-proof panel includes a support seal mounted on the periphery of the bottom surface of the outer peripheral shoulder, abutting against the lower end face of the outer peripheral shoulder and opposite the fastening frame, preferably opposite the interface seal (the support seal abuts against the protected structure or a fixed pressure plate connected to the structure), and extending a portion onto the insulation material to cover the embrittlement area. The support seal is preferably fixed by adhesive bonding.

[0034] In one embodiment, the support seal is in the form of a frame or a sealing plate that covers and extends continuously to the lower end face of the outer peripheral shoulder and the entire insulating material. The support seal includes perforations corresponding to the fixing holes on the outer peripheral shoulder, holes on the fastening frame, and holes on the interface seal, for securing the explosion-proof plate to the structure requiring protection. Bolts are preferred for securing the plate.

[0035] In one application of explosion-proof panels, the panel also includes a rigid plate, typically a metal plate, which is tightly fitted against the insulating material facing the main surface of the enclosure (to seal the enclosure). The rigid plate is secured to fasteners that can be connected to the inside of the enclosure. Welding is preferably performed near the corners of the enclosure. The rigid plate may also include some peripheral protrusions that fit tightly against the inner side of the outer peripheral wall of the enclosure. The insulating material is completely enclosed by the enclosure and the rigid plate.

[0036] In one embodiment, the housing covered with thermal insulation material is higher than the connection surface, the housing (thermal insulation material) should be located on the outside of the structure, and the explosion-proof plate should be connected to the structure by an outer shoulder.

[0037] In one embodiment, the explosion-proof panel includes an additional thermal insulation material added below the plane of the outer peripheral shoulder (the additional thermal insulation material protrudes outside the housing filled with thermal insulation material), the additional thermal insulation material being directly fixed to the thermal insulation material inside the housing, primarily by adhesive bonding, and / or fixed to the support seal.

[0038] In one embodiment, the explosion-proof plate includes an insulating box mounted facing the inside of the housing (below the housing). The size of the insulating box matches the size of the embrittlement zone; for example, the size of the insulating box is only equivalent to the size of the inner cross-section defined by the embrittlement zone, or the size of the insulating box is slightly smaller than the size of the inner cross-section defined by the embrittlement zone. The insulating box contains additional insulating material and is connected to the housing (bottom of the housing). The insulating box is mechanically fixed to the housing, preferably by a connector inside the housing. Thus, the insulating box encloses the portion of the housing opposite the main surface. The design (shape and size) of the insulating box allows it to rotate through the inner cross-section defined by the embrittlement zone; in particular, the insulating box must have at least one sidewall on the side of the embrittlement zone with an inclined surface facing inwards towards the interior of the insulating box.

[0039] This utility model also relates to a storage structure, which includes at least one explosion-proof plate of this utility model. In this application, "storage structure" refers to any enclosed structure or enclosure in which a product can at least temporarily reside or flow. Such structures are more often silos, hoppers, storage chambers, agitators, filtration systems, pipelines, bucket elevators, and ESS containers (including but not limited to).

[0040] Finally, this utility model relates to a method for manufacturing the explosion-proof plate of the present utility model, which includes processing fixing holes and embrittlement zones while prefabricating fracture elements with a metal sheet (blank), and the metal sheet is stamped to form a three-dimensional shell with a full and continuous surface.

[0041] The beneficial effects of this utility model are: the explosion-proof plate of this application meets safety requirements, will not lose its sealing performance over time, and is simpler to manufacture. Attached Figure Description

[0056] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] In the following description, the terms “height”, the adjectives “upper”, “lower”, “high” and “low” are used to better understand the present invention, for example, the explosion-proof plate is installed on top of the structure that needs protection.

[0058] Figure 4 The explosion-proof plate 1 of this invention, as shown, is used to protect the storage structure S or surrounding structures from explosion in the event of an abnormal overpressure inside. The explosion-proof plate 1 is fixed to the storage structure S by a support plate S' integrally connected to the storage structure S (bolts are not shown in the illustration).

[0059] Therefore, the explosion-proof plate 1 is used to seal the opening of the storage structure S, primarily for outdoor storage structures S, such as containers housing energy storage systems (ESS). The explosion-proof plate 1 can be fixed around the opening of the storage structure S by screws passing through both the explosion-proof plate 1 and the storage structure S. In the event of overpressure, the central portion of the explosion-proof plate 1 can tear, while the remaining portion remains connected to the storage structure S. The explosion-proof plate 1 is fixed to the corresponding mounting surface by fixing holes 10 around its perimeter.

[0060] like Figure 1 and Figure 2 As shown, the explosion-proof panel 1 includes a fracture element 1', which in turn includes an embrittlement zone 11 that will tear under overpressure inside the storage structure S, a thermal insulation material 2 that insulates the structural opening covered by the explosion-proof panel 1, a fastening frame 3 that presses the fracture element 1' tightly onto the protected storage structure S, a contact surface sandwich structure interface seal 4 between the fastening frame 3 and the fracture element 1', and a support seal 5 (closely attached to the opening of the protective structure) opposite to the interface seal 4 and the fastening frame 3. The interface seal 4 and the support seal 5 are mounted facing each other on each surface opposite to the fracture element 1' and are attached to the embrittlement zone 11 to seal the area.

[0061] The explosion-proof plate 1 here is rectangular, but it can also be square, circular or any other geometric shape.

[0062] According to this invention, the fracture element 1' of the explosion-proof plate 1 is formed as a three-dimensional shell with an integrally molded surface, and the thermal insulation material 2 is located inside the shell. The three-dimensional shell (hereinafter also referred to as the shell) includes a main surface 12 or bottom surface, an outer peripheral wall 13, and an outer peripheral shoulder 14 opposite to the main surface 12, the outer peripheral shoulder 14 extending from the outer peripheral wall 13 to the outside of the outer peripheral wall 13. The outer peripheral shoulder 14 forms a frame, constituting the fixing surface of the explosion-proof plate 1. The fixing hole 10 is machined on the outer peripheral shoulder 14.

[0063] The three-dimensional shell is manufactured as a single, continuous, three-dimensional molded surface. This continuous, one-piece molded surface is obtained by stamping a sheet metal. This three-dimensional, one-piece molded shape of the sheet metal raises the main surface 12 and provides an internal receiving space V for accommodating the insulation material 2. Furthermore, this one-piece molded sheet metal also forms a continuous surface of the shell at each contour change, namely between the main surface 12 and the outer peripheral wall 13, at the corner 13' of the outer peripheral wall 13, and between the outer peripheral wall 13 and the outer peripheral shoulder 14, ensuring a complete seal of the interior of the shell, thereby completely sealing the insulation material 2. In addition, the shell has the advantage of being able to directly form the outer side of the explosion-proof panel, which is in contact with the external environment of the protected structure, because its one-piece continuous surface (including at the location of the outer peripheral wall 13) has perfect sealing performance.

[0064] The housing includes an embrittlement zone 11, which directly provides fracture functionality for the fracture element 1' and the explosion-proof plate 1. The embrittlement zone 11 is located within the outer peripheral shoulder 14 between the fixing hole 10 and the outer peripheral wall 13, at a certain distance from the bottom 13A of the outer peripheral wall 13 (at a certain distance from the starting point of the outer peripheral wall). The embrittlement zone 11 is covered by the interface seal 4, which will be described in detail later. Therefore, the explosion-proof plate 1 of this invention integrates explosion-proof and heat insulation functions. The housing is both a sealed container for the insulation material and a fracture plate in the event of an explosion. The advantage of this explosion-proof plate 1 design is that the insulation material is primarily placed outside the protected structure. When the explosion-proof plate 1 is installed on the structure to be protected, the housing is located outside the structure and is in direct contact with the external environment and harsh weather. Advantageously, the stamping design minimizes the inclination of the outer peripheral wall 13 relative to the vertical direction (e.g., Figure 4 As shown), it is therefore as flat as possible relative to the bottom surface 13A near the embrittlement zone 11 and kept straight with the structure to be protected, thereby maximizing the volume of the insulation material to optimize the insulation effect relative to the structural opening. Figure 5 and Figure 6 It is also shown that the upper shape 2A of the thermal insulation material 2 is adapted to the lower shape 2B, thus ensuring the entire internal volume V of the shell, including the corners 13' and the bottom surface 13A of the shell.

[0065] The thickness of the metal sheet constituting the shell is preferably between 0.5-1.2 mm, for example, around 0.8 mm. The embrittlement zone 11 is located within the thickness range of the metal sheet; when the pressure in the protected structure is excessive, the embrittlement zone 11 will fracture. For example, the embrittlement zone 11 consists of discontinuous gaps along the thickness of the sheet (generally laser-made and connected by fragile solid components). The embrittlement zone 11 is arranged on all or part of the circumference of the outer peripheral shoulder 14. Depending on the specific circumstances of the explosion-proof plate 1, the embrittlement zone 11 can extend around the entire circumference or only a portion thereof, such as... Figure 3 The U-shape is shown. In this case, the embrittlement zone 11 extends to three sides, and the fourth side has no embrittlement zone, so as to form a connection point at the opening, while ensuring that the explosion-proof plate 1 remains integral with the structure through the outer peripheral shoulder 14.

[0066] More conveniently, the explosion-proof plate 1 includes a grounding point (e.g., Figure 2 and Figure 4 (As shown). For example, the grounding point is a U-shaped grounding piece 1 (located on the outer periphery of the shoulder) (as shown). Figure 4 (As shown). The grounding plate 1” is integrated with the housing, a portion of which forms part of the outer peripheral shoulder 14 (this part is obtained during manufacturing, equivalent to an extension cut from the original steel sheet blank) and a convex corner (obtained by folding). This convex corner provides a space to accommodate the interface seal 4 and the fastening frame 3, and the convex corner (grounding plate) is in direct contact with the fastening frame 3 (made of metal). The grounding plate 1” has a hole 10’ that aligns with the fixing hole 10 on the outer peripheral shoulder 14. The advantage of the grounding plate 1” is that it provides a grounding connection for the explosion-proof plate 1 without any additional components. The grounding plate connection can be made functional when mechanical fasteners (such as screws or nuts) are added; electrical continuity can be established by simply tightening the grounding plate 1” through the support plate S.

[0067] To ensure the sealing of the explosion-proof plate 1 and the shell 1' in the embrittlement zone 11, and to fix the explosion-proof plate and the shell 1' around it, the explosion-proof plate 1 includes an interface seal 4 and a fastening frame 3.

[0068] The geometry of the fastening frame 3 corresponds to the periphery of the fracture element 1'. The fastening frame 3 is arranged opposite to the entire outer peripheral shoulder 14, but does not cover the embrittlement zone 11. The fastening frame 3 is preferably composed of several independent parts to save on manufacturing materials and costs. Figure 1 and Figure 3As shown, the fastening frame 3 has at least two parts or components 3A and 3B. The explosion-proof plate here is rectangular, and the embrittlement extends in a U-shape along one short side and two long sides. The fastening frame 3 is divided into four parts: web 30, wing 31, wing 32, and a fourth part 3B. The first component 3A of the fastening frame 3 is U-shaped, extending along the U-shaped perimeter of the embrittlement zone 11. The fastening frame 3 does not cover the embrittlement zone 11; only the interface seal 4 and its first part 40, second part 41, and third part 42 cover the embrittlement zone. Figure 3 In the diagram, the embrittlement zone 11 is shown, but is not actually visible as it is covered by the interface seal 4. The first component 3A consists of three parts: a web 30 and two opposing flanges 31 and 32. The web and flanges form three separate parts, but are joined at the U-shaped corner and become one unit after assembly (when the explosion-proof plate is bolted to the structure). The flanges 31 and 32 of the first component 3A of the fastening frame extend along the two long sides of the explosion-proof plate, and the web 30 extends along one short side. These three sides correspond to the sides that constitute the embrittlement zone 11. Under excessive pressure, the U-shaped embrittlement zone 11 automatically breaks, the shell plate opens, and is secured by the fourth side without the embrittlement zone as the connection point. Therefore, the connection point of the fracture element 1' is opposite to the U-shape and extends along the fourth side opposite to the web 30 of the fastening frame, while also extending along the fourth part 3B of the fastening frame. The fourth part 3B of the fastening frame is not bolted to the first component 3A (nor is it butt-fitted), particularly not to the directly adjacent components wing plates 31 and 32. The fastening frame 3 preferably has slots 33 along its thickness and width, leading to the exterior of the explosion-proof plate. These slots 33 form grooves and channels in the fastening frame 3, allowing water to drain and preventing water accumulation around the housing. These slots are provided here because the fourth part 3B is not connected to the other parts of the fastening frame (wing plates 31 and 32).

[0069] The geometry of the interface seal 4 is consistent with that of the fastening frame 3. The interface seal 4 is sandwiched between the outer peripheral shoulder 14 and the fastening frame 3, and covers the brittle area 11. Therefore, the interface seal 4 extends from the fastening frame 3, facing the inner wall 13 (e.g., Figure 1 , Figure 3 and Figure 4 The interface seal 4 extends a few millimeters from the fastening frame 3. The interface seal 4 is preferably adhered to the upper end face 14A of the outer peripheral shoulder 14. However, there is no interface seal at the gap 33 of the fastening frame 3, so water can flow from the plane of the bottom surface 13A of the housing to the outside of the housing. The interface seal 4 is also divided into several (four) parts here: the first part 40, the second part 41, the third part 42, and the fourth part 43 (in... Figure 3(Illustrated by dashed lines, located below the fastening frame 3), these four parts basically correspond to the web 30, wing 31, wing 32 and fourth part 3B of the fastening frame 3. However, these four parts (first part 40, second part 41, third part 42 and fourth part 43) are fully mated around the perimeter, designed to systematically cover the corners of the outer peripheral shoulder 14 by mating outside the corners. Preferably, the four parts (first part 40, second part 41, third part 42 and fourth part 43) are mated together by a concave-convex form 44. The interface seal 4 (such as...) Figure 3 The connection lines of the connection shapes 44 of the various parts (first part 40, second part 41, third part 42 and fourth part 43) are not perpendicular to the connection lines of the fastening frame, especially not to the connection lines of the three U-shaped parts (web plate 30, wing plate 31 and wing plate 32) of the fastening frame.

[0070] The support seal 5 provides a peripheral seal between the explosion-proof plate 1 (especially the housing) and the protected structure. The support seal 5 is made of a compressible, (potentially) food-grade material, and is itself constructed of a known material. The support seal 5 is preferably bonded to the housing, and preferably bonded during the manufacture of the explosion-proof plate. The support seal 5 is integral with at least a portion of the lower end face 14B of the entire outer peripheral shoulder 14 and the thermal insulation material 2 (e.g., Figure 4 (As shown).

[0071] according to Figure 2 and Figure 4 In the installation example shown, the support seal 5 forms a frame whose shape is the same as the outer periphery of the housing. The support seal 5 covers the lower end face 14B of the outer peripheral shoulder 14, covers the embrittlement area 11, and extends beyond the insulating material 2. The frame-type support seal 5 can be divided into several parts, such as a first part 51, a second part 52, a third part 53, and a fourth part 54, for a total of four parts (e.g., Figure 2 As shown), they are connected together to form a continuous sealing surface. Figure 3 The dashed line in the figure represents the support seal 5, which is located below the outer periphery shoulder 14 of the housing. The components of the support seal 5 preferably adopt a concave-convex connection shape 50'. The connection line of the connection shape 50' of the support seal 5 is offset relative to the connection line of the connection shape 44 of the portions 40-43 of the interface seal 4 (e.g., ...). Figure 3 (As shown).

[0072] according to Figure 5 and Figure 6 In another installation example shown, the support seal 5 is in the form of a solid plate, which covers the lower end face 14B of the outer peripheral shoulder 14, covers the brittle area 11, and covers the insulating material 2. The support seal 5 is preferably attached to the bottom surface of the insulating material 2 by means of double-sided tape or the like.

[0073] The entire perimeter of the explosion-proof plate 1 is secured by fastening devices, primarily bolts (not shown in the figure). For example, the tightening device includes a screw and a nut, the screw head being accessible from the outside of the explosion-proof plate 1, at the fastening frame. The nut connects to the screw body, opposite the screw head, and is located inside the structure. A washer is preferably placed between the screw head and the fastening frame 3.

[0074] Each fixing hole 10 on the housing corresponds to a hole 35 on the fastening frame 3, a hole 45 on the interface seal 4, and a hole 50 on the support seal 5. The diameters of the holes 45 and 50 on the interface seal 4 and the support seal 5 correspond to the cross-section of the tightening device (such as a screw or threaded rod) so that it can be inserted into the fixing hole 10 of the explosion-proof plate. In this way, when the interface seal and the support seal are under pressure, the sealing material will be inserted into the thread of the tightening device, thereby ensuring a perfect seal.

[0075] Explosion-proof plate 1 may include fastening limiting device 15 ( Figure 10 (A modified version) allows the operator to feel that the tightening torque of the fastening limiting device 15 is just right to optimally compress the supporting seal 5 when fixing the explosion-proof plate. These fastening limiting devices 15 are integral with the housing, especially with the peripheral shoulders 14 around the fixing holes 10. The fastening limiting devices 15 form evenly distributed bosses around each fixing hole 10 to uniformly compress the interface seal 4 and the supporting seal 5.

[0076] The fastening limiting devices 15 are preferably arranged on the upper surface 14A and lower surface 14B of the outer peripheral shoulder 14, respectively, to simultaneously calibrate the clamping force of the support seal 5 and the interface seal 4. Calibration of a portion of the outer peripheral shoulder 14, and calibration of the brittle areas 11 covered on each surface of the shoulder by the interface seal 4 and the support seal 5, prevents excessive pressure on the brittle areas 11, which could otherwise be over-clamped and tear the brittle areas 11. When the thickness of the interface seal 4 and the support seal 5 is 4 mm, the height of the boss is 2 mm.

[0077] Figure 7 and Figure 8A modified example design of the housing 1' is shown, which is closed relative to the bottom 12 by a solid rigid plate 16. The rigid plate 16 is typically a metal plate. Thermal insulation material 2 is inserted into the internal space V of the housing before the rigid plate 16 is fixed. The rigid plate 16 preferably includes a peripheral protrusion 16' perpendicular to its inner surface 16A, so that the rigid plate 16 is combined with the housing via the peripheral protrusion 16', which enters the internal space V of the housing and abuts against the outer peripheral wall 13. The rigid plate 16 is fixed to the housing by fasteners 17 integrally formed with the housing interior. The fasteners 17 include fixing members 17' parallel to the plane of the rigid plate 16 and opposite to the base 12, preferably coplanar with the outer peripheral shoulder 14. The fasteners 17 are preferably arranged at the four corners of the housing from both sides of one corner of the outer peripheral wall 13. The fasteners 17 are preferably integrally fixed to the outer peripheral wall 13 by welding.

[0078] Figure 9 and Figure 10 Another modification of the explosion-proof plate 1 is shown, which not only has thermal insulation material on the upper part of the housing sealing groove, but also additional thermal insulation material 2' on the lower surface of the explosion-proof plate, i.e., the inner side of the protected structure. The additional thermal insulation material 2' is preferably integrated with the lower surface of the explosion-proof plate and is adhered to the supporting seal 5 by adhesive.

[0079] for Figure 9 The explosion-proof plate 1 and the supporting seal 5 form a supporting seal frame 5 (such as...). Figure 2 As shown, the additional thermal insulation material 2' is bonded to the supporting sealing frame 5, creating an air layer 51 on the contact surface opposite the thermal insulation material 2 and inside the supporting sealing frame 5. For example, each surface of the supporting sealing frame 5 has double-sided adhesive, which is connected to the upper thermal insulation material 2 on the upper surface and to the additional thermal insulation material 2' on the lower surface.

[0080] for Figure 10 The explosion-proof plate 1 and the supporting seal 5 form a solid supporting seal plate 5 (e.g., Figure 6 As shown, the additional thermal insulation material 2' is adhered to the bottom surface of the supporting sealing plate 5, preferably along its entire surface. For example, double-sided tape is used to adhere the additional thermal insulation material 2' to the supporting sealing plate 5.

[0081] Figure 11 and Figure 12Another (non-limiting) arrangement example is shown, in which the additional thermal insulation material 2' is placed below the housing 1' (bottom surface). Here, the connection point of the explosion-proof plate is located on the long side, arranged along the fourth section 3B, separated from the rest of the fastening frame. The explosion-proof plate 1 includes an insulation box 6, preferably a metal box, which is arranged around the housing opposite the main surface 12. The internal receiving space of the insulation box 6 is V', containing the additional thermal insulation material 2'. The thermal insulation material 2 and the additional thermal insulation material 2' can be the same material, with the thermal insulation material 2 filling the internal space V of the housing and the additional thermal insulation material 2' filling the internal space V' of the insulation box 6. The insulation box 6 is arranged opposite to the interior of the housing 1 and does not need to pass outside the embrittlement zone 11. The outer wall 60 of the insulation box 6 is preferably substantially parallel to the outer peripheral wall 13 of the housing.

[0082] To secure the insulation box 6, the housing preferably includes a metal frame 18, which is connected to the interior of the housing via a fixing tab 18' welded to the inner side of the main surface 12, and simultaneously connected to the outer peripheral wall 13. The insulation box 6 has a closed bottom surface 61, an outer peripheral wall 60 (with the same thickness as the additional insulation material layer), and an inner peripheral protrusion 62 opposite to the bottom surface and facing the interior of the box, perpendicular to the outer peripheral wall 60, to secure the insulation box 6 to the frame 18 of the housing. The insulation box 6 preferably also includes a reinforcing frame 63, which is fixed to the outer peripheral protrusion 62 (preferably also fixed to the inner side of the outer peripheral wall 60 of the insulation box 6 via a connecting tab 63'), and connected and fixed to the frame 18 of the housing. The support seal 5 forms a support frame here, extending to the entire lower surface of the outer peripheral shoulder 14, covering the embrittlement area 11, and extending opposite the frame 18 of the housing and the reinforcing frame 63 of the outer peripheral protrusion 62. The insulation box 6 is fixed as follows: the frame 18 of the shell is connected to the inside of the shell; the frame 63 of the insulation box 6 is removed from the insulation box 6 and first fixed separately to the frame 18 of the shell, for example by screws; the additional insulation material 2' is inserted into the insulation box 6, and then the insulation box 6 is put back into the frame 63, preferably inserted into the frame 63 for immediate fixation (for example, the insulation box 6 is provided with a socket, and the fixing connecting piece 63' can be inserted into the socket), and mechanically connected by the rivets on the fixing connecting piece 63' on the frame 63.

[0083] Finally, depending on the geometry and size of the openings in the structure to be protected, when the explosion-proof plate 1 contains an insulation box 6 inside the inner section defined by the embrittlement zone 11 below the shell, the insulation box 6 should be designed (in shape and size) to pass through the inner section defined by the embrittlement zone 11 when the embrittlement zone 11 cracks and the shell-insulation box assembly rotates, as... Figure 13As shown by the dotted line in the diagram. Therefore, the shape and geometry of the insulation box will be adjusted so that when the shell is opened and the insulation box 6 begins to move (rotate) outward, the insulation box 6 can pass through the inner section defined by the embrittlement zone 11, that is, it can pass through the internal range defined by the embrittlement zone 11, as shown by the dotted line in the diagram. Figure 13 As shown. For example, the insulated box 6, which is usually roughly rectangular in shape, has a sloping edge on the outer wall 60 opposite the opening connection point of the shell 1' that moves towards the bottom surface 61 (inside the box).
