Description

Technical Field

[0001] This invention relates to the field of chemical liquid storage technology, and more specifically, to a safe storage cabinet for flammable liquids that conforms to the EN14470-1 standard. Background Technology

[0002] In recent years, accidents involving explosions of hazardous chemicals have occurred frequently. The State Administration of Work Safety has paid close attention to safety in production and storage. In terms of the safe storage of flammable liquids, more and more companies have chosen fireproof safety cabinets.

[0003] Currently, the most common type of fireproof safety cabinet on the market meets the American FM6050 standard. However, these cabinets can only withstand fire for 10 minutes after a fire breaks out. After 10 minutes, the hazardous chemicals stored inside will explode due to the continuously rising temperature, causing personal injury and property damage.

[0004] The main reasons for this are as follows:

[0005] 1. In the event of a fire, the gaps in the cabinet doors and the air inlets and outlets of existing safety storage cabinets cannot be sealed in time, allowing fire sources and heat to still enter the cabinet even after the doors are closed.

[0006] 2. Existing security storage cabinets cannot automatically close the cabinet door based on ambient temperature, which can easily lead to accidents if the user forgets to close the door;

[0007] 3. The air inlet and outlet of the cabinet cannot automatically close according to the ambient temperature, which means that in the event of a fire, the fire source and heat cannot be blocked from entering the cabinet. Summary of the Invention

[0008] Due to the existence of the above-mentioned problems, this application proposes a flammable liquid safety storage cabinet, the purpose of which is to overcome the problem that the cabinet in the prior art cannot block heat and fire sources and has poor fire protection effect.

[0009] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0010] A flammable liquid safety storage cabinet includes a cabinet body, a door panel assembly, an air inlet assembly, and an air outlet assembly. The cabinet body contains a shelf assembly. The cabinet body is composed of a top panel, a bottom panel, a left side panel, a right side panel, and a back panel. The top panel, bottom panel, left side panel, right side panel, and back panel are all constructed of fire-resistant panels. First expansion devices are provided at the joints between the top panel, left side panel, right side panel, and bottom panel and the door panel assembly to seal any gaps in the cabinet body.

[0036] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0037] See Figures 1 to 3The diagram shown is a schematic representation of the overall structure of one embodiment of this application. This application includes a cabinet 1, a door panel assembly 2, a shelf assembly 3, a drain collection trough assembly 4, an automatic door closing device assembly 5, an air outlet assembly 6, a cabinet decorative cover 7, and an air inlet assembly 8, etc. The door panel assembly is installed at the front of the cabinet 1. The door panel can be installed on the cabinet 1 via a rotating shaft, hinge, or other means. The number of door panels is not limited and can be set according to the actual needs of the cabinet 1. The shelf assembly 3 is installed inside the cabinet 1 by screws. The number of shelf assemblies 3 can be set according to actual needs and is not limited to the number set in this embodiment. The drain collection trough assembly 4 is located at the lower end inside the cabinet 1 and is used to collect leaked liquid.

[0038] The cabinet 1 consists of a top panel, a bottom panel, a left side panel, a right side panel, and a back panel. The main body of the cabinet 1 is constructed from a fire-resistant board assembly 11, which is composed of multiple layers of fire-resistant boards. A metal cover plate 12 is applied to the outside, forming a metal frame on the outer surface of the cabinet 1 to enhance its strength and prevent damage to its structure from accidental collisions. An inner liner 13, made of particleboard, is fixed to the fire-resistant board assembly 11, effectively resisting the corrosion of acidic and alkaline chemicals.

[0039] See Figure 4 As shown, the cabinet 1 has a layered board 14 inside. To support the layered board 14, a horizontal support 16 and a vertical support 17 are provided at its bottom. A sealing element 15 is provided at the junction of the layered board 14 and the cabinet 1, allowing the cabinet to maintain a relatively sealed overall appearance. An internal space A is formed between the layered board 11 below and the cabinet 1. A door-closing auxiliary space B is formed between the layered board 11 above and the cabinet 1. A door-closing auxiliary space B is provided in the door-closing auxiliary space B. The door-closing auxiliary space B uses a magnet, and the magnet will not deform or fail due to heat in the event of a fire. An air outlet 113 is provided at the upper right side of the cabinet 1, located within the internal space A, and an air inlet 114 is provided at the lower left side panel.

[0040] Please see again Figure 4 and Figure 6 As shown, a first expansion device 111 is provided at the junction of the top plate, left side plate, right side plate, and bottom plate with the door panel assembly to seal the gaps in the cabinet. The first expansion device 111 will expand immediately after being heated, filling the gap between the door and the cabinet, thus blocking fire and heat sources.

[0041] like Figure 5As shown, a support beam 18 is installed in the middle of the bottom of the cabinet 1. The connection method of the support beam 18 is not limited to welding, and the number is not limited to one. It can provide stability for the cabinet. Bottom support beams 19 are installed on the left and right sides of the bottom of the cabinet 1, and the installation connection method is not limited to bolts. The support beams 18 and bottom support beams 19 improve the stability of the bottom of the cabinet 1. Most directly, the cabinet 1 can be quickly transported by forklifts, pallet jacks, and other transportation tools. A grounding nut 112 is installed on the left side of the cabinet 1. One end of a dedicated grounding wire is connected to the grounding nut 112, and the other end is connected to the grounding grid of the building where the cabinet 1 is located. This can eliminate static electricity generated by the cabinet and avoid the risks caused by static electricity from sparks. The bottom of the cabinet is provided with a cabinet decorative cover plate 7.

[0042] See Figure 8 and Figure 9 As shown, the door panel assembly 2 of this application includes a door panel 21, a door lock 22, and an automatic door closing device assembly 5. The door panel 21 is composed of a fireproof board assembly 214, with an inner door liner 212 located inside the fireproof board assembly. The door panel 21 has rotating pivot points 213 at its upper and lower ends for opening and closing the door between the assembly 2 and the cabinet 1. The door panel is fixed to the front opening of the cabinet. Second expansion devices 211 are provided around the perimeter of the door panel 21. Retractable locking pins 221 are provided at both the upper and lower ends of the door panel 21. The door lock 22 is located on the door panel, as shown... Figure 9 As shown, the door lock 22 moves up and down in conjunction with the locking pin 221. The linkage between the door lock 22 and the locking pin via the connecting line 221 is a conventional technique and will not be described in detail here. A locking device 115 with a slotted hole is provided on the cabinet 1 corresponding to the locking pin 221.

[0043] See Figure 3 and Figure 12The image shows the automatic door closing device assembly 5 of this application. The automatic door closing device assembly 5 of this application can adjust the closing angle according to temperature. The automatic door closing device assembly 5 includes a door closer body 51, a door closer connecting rod 52, a fixing device 53, a door closer telescopic rod 54, a rotating rod fixing device 55, a rotating rod 56, a connecting piece 57, a wire 58, a tension spring 59, a tension spring fixing device 510, a limiting structure 511, a temperature control device, etc. The door closer body 51 is fixed to a door panel 21, and the door closer body 51 is connected to the door closer connecting rod 52. The fixing device 53 is fixed within the door closing auxiliary space B, and the fixing device 53 is provided with the door closer telescopic rod 54, the end of which is connected to the end of the door closer connecting rod 52. The rotating rod fixing device 55 is fixed within the door closing auxiliary space B, and one end of the rotating rod 56 is fixed thereon. The other end of the rotating rod 56 is provided with a connecting piece 57 and a wire 58. One end of the connecting piece 57 is connected to a tension spring 59 and a tension spring fixing device 510, and the other end of the connecting piece 57 is connected to a temperature control device. The wire 58 is connected to the door closer connecting rod 52, and a fixed limiting structure 511 is provided on the outer side of the rotating rod 56. The temperature control device includes at least one temperature sensing device 512 and a temperature sensing device fixing seat 513. Each temperature sensing device 512 is connected to the connecting piece 57 and the temperature sensing device fixing seat 513. When the ambient temperature reaches the 50°C limit temperature specified in EN14470-1, the corresponding temperature sensing device 512 senses this and automatically separates the connecting piece 57 from the temperature sensing device fixing seat 513. Then, the tension spring device pulls the rotating rod 56 to move by an angle, and the rotating rod 56, through the wire 58, drives the door closer connecting rod 52 and the door closer body 51 to move by an angle toward the fixing device 55 (i.e., the door catch device 110).

[0044] Under normal conditions, when the door panel 21 is opened, the door closer connecting rod 52 and the door closer telescopic rod 54 will rotate, and the opening angle of the door panel 21 will be limited by the limiting device 513. The temperature sensor 512 constantly monitors the ambient temperature. When the ambient temperature reaches 50°C as specified in EN14470-1, the temperature sensor 512 will automatically separate. With the help of the tension spring, the rotating rod 56 and the connecting piece 57 will be pulled inward around the rotating rod fixing device 55 as the axis. At the same time, the door closer connecting rod 52 will be pulled by the wire 58, and the door panel 21 in the open state will be pulled to the closed state, avoiding the risk of failure to close the door panel 21 in time during a fire.

[0045] See Figure 13 As shown, the air outlet assembly is equipped with a temperature-sensing sealing device 6, which closes the air outlet assembly according to the external environment.

[0046] The temperature-sensing sealing device 6 includes an air outlet duct 61, a screw 62, a limiting device 63, valve plates 641 and 642, a torsion spring 65, a temperature-sensing device 66, and a temperature-sensing limiting device 67. The air outlet duct 61 is installed at the air outlet and has a hollow, circular interior. The screw 62 passes through the middle of the air outlet duct, and its end is fixed by the limiting device 63. Both ends of the two valve plates 641 and 642 are fixed to the screw 62 from both ends. The torsion spring 65 is located on the screw 62, and the torsion spring 65 connects (or can be driven) the two valve plates 641 and 642 in a twisted state. The temperature-sensing device 66 is fixed at both ends to the opposite sides of the two valve plates 641 and 642. When the temperature sensing device 66 senses the limiting temperature, it releases the two valve plates 641 and 642, which then rotate under the torque of the torsion spring 62. Two temperature-sensing limiting devices 67 are respectively disposed at the ends of one of the valve plates 641 and 642 to limit the direction of rotation of the valve plates 641 and 642.

[0047] See Figure 14 The diagram shows the structure of the air inlet assembly of the present invention. The air inlet assembly 8 includes a cover plate 81, a tension spring 82, a sliding groove 83, a sealing device 87, a connecting line 84, and a temperature sensing device 85. The cover plate 81 is fixed to the cabinet 1 by a fastener 86 and corresponds to the air inlet. The cover plate 81 has honeycomb through holes 811. Sliding grooves 83 are provided along both sides of the cover plate 81. The sealing device 87 is fixed in the sliding groove 83. The first end of the tension spring 82 is fixed to the cover plate 81 and the cabinet 1 by a tension spring fastener 88, and the end of the tension spring 82 is connected to one side of the sealing device 87. The other side of the sealing device 87 is connected to the temperature sensing device 85 by the connecting line 84, and the temperature sensing device 85 is fixed at the honeycomb through hole 811. The length of the connecting line 84 is the distance from the end of the sliding groove to the temperature sensing device.

[0048] When the temperature sensing device 811 senses that the ambient temperature exceeds the set value (when the ambient temperature reaches 70°C as specified in EN14470-1 standard), it automatically disassembles. Under the action of the tension spring 82, the sealing device 87 moves towards the tension spring fixing member 88 until it covers the air inlet, completely blocking the air inlet and preventing fire or heat sources from entering the cabinet.

[0049] Please see Figure 10The diagram shown is a structural schematic of the shelf assembly of this application. The shelf assembly 3 includes a shelf 31, a shelf support 32, and a shelf fastener 33. The shelf 31 is adjusted and fixed in position within the cabinet via the shelf fastener 33 to accommodate containers of different heights. The shelf 31 features a bent and pleated edge design along its length, enabling its uniform load-bearing capacity to meet the 75 kg standard of EN14470-1. The shelf 31 and the shelf support 32 are made of, but are not limited to, galvanized steel.

[0050] Figure 11 The diagram shown is a structural schematic of the leakage collection tank assembly of this application. The leakage collection tank assembly includes a leakage collection tank base 41, a support bracket 42, a longitudinal flow guiding sealing strip 43, and a transverse flow guiding sealing strip 44.

[0051] The spill containment base 41 is installed at the bottom of component 1-1. When a chemical container stored above shelf assembly 3 leaks, all the leaked chemicals will flow into the spill containment base 41, preventing any impact on the surrounding environment. The four-sided sealing design of the spill containment base 41 also meets the requirements of EN14470-1 standard regulations. The support bracket 42 is installed inside the spill containment base 41. When there is a leak of hazardous chemicals inside the spill containment base 41, the support bracket 42 can be lifted, and appropriate absorbent materials can be used to absorb and recover the leaked chemicals. The support bracket 42 is designed with multiple, but not limited to, round holes, to facilitate the rapid flow of leaked hazardous chemicals to the bottom of the spill containment base 41. The longitudinal flow-guiding sealing strip 43 and the transverse flow-guiding sealing strip 44 ensure a better fit between the spill containment base 41 and the bottom of the cabinet interior, providing shock absorption during transportation. The spill containment base 41 and the support bracket 42 are made of, but not limited to, galvanized steel sheet.

[0052] In summary, the safety storage cabinet designed using this application meets the EN14470-1 standard and can automatically close when the ambient temperature reaches 50°C. The automatic door closing device component 5 allows for multiple fire resistance time periods, meeting the requirements of customers with different fire protection ratings.
