Description

Technical Field

[0001] This utility model relates to the field of hazardous materials storage technology, specifically to an outdoor hazardous materials temporary storage cabinet. Background Technology

[0002] Hazardous materials storage cabinets have a long production cycle and high cost, so most places usually do not have hazardous materials storage areas, such as gas stations. In order to reduce the construction cost of hazardous materials storage cabinets, containers are used to make temporary storage cabinets. Containers can be spliced ​​according to the actual situation (supporting up to five containers). The interior is divided into three partitions to separate solids and liquids, and also to prevent cross-contamination between solids and liquids.

[0003] When liquids are stored, the storage device may corrode over time, leading to leaks. Leaks may initially seep into the ground, potentially contaminating it. Leaks may not be detected immediately, and due to the weight of the liquid, dealing with leaks takes a long time. Therefore, it is necessary to collect the leaked liquid to prevent further contamination. However, if the damaged container is close to the edge of the storage tank, the leaked liquid may flow into the gap between the storage tank and the collection trough, eventually spilling onto the floor and contaminating the storage tank floor. Utility Model Content

[0004] The purpose of this invention is to provide an outdoor hazardous materials storage cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor hazardous materials storage cabinet, comprising: a main body of the storage cabinet, wherein two partition boards are fixedly connected inside the main body of the storage cabinet, and the partition boards divide the main body of the storage cabinet into a liquid area, a solid area and an emergency area;

[0006] The liquid zone includes:

[0007] A liquid storage rack is fixedly connected to the inner wall of the main body of the temporary storage cabinet, and the liquid storage rack has through holes inside;

[0008] A conical drainage channel is fixedly connected to the bottom of the liquid storage rack;

[0009] A seepage-proof tray is fixedly connected to the inner wall of the temporary storage cabinet body. The seepage-proof tray is located directly below the conical drainage channel, and the output end area of ​​the conical drainage channel is smaller than the top area of ​​the seepage-proof tray.

[0010] An overflow collection tank is installed on the outside of the main body of the temporary storage cabinet. A drainage pipe is connected between the overflow collection tank and the anti-seepage tray. A safety one-way valve is installed inside the drainage pipe.

[0011] Preferably, the cavity inside the seepage-proof tray is conical, and the lowest point of the seepage-proof tray is connected to the drainage pipe, which is inclined at a certain degree.

[0012] Preferably, the height of the overflow collection trough is slightly lower than the height of the seepage-proof tray, and a guide pipe is installed inside the overflow collection trough.

[0013] Preferably, an object placement rack is installed inside the solid area, and the object placement rack is made of an anti-static material.

[0014] Preferably, an explosion-proof suction pump is installed inside the emergency zone, with one end of the pump extending through the main body of the temporary storage cabinet to the outside of the cabinet. A liquid nitrogen inerting system is installed inside the emergency zone near the pump.

[0015] Preferably, a sandwich base plate is fixedly connected to the bottom of the main body of the temporary storage cabinet, a sealed electromagnetic suction door is rotatably connected inside the main body of the temporary storage cabinet, a facial recognition device is installed on the outer surface of the sealed electromagnetic suction door, and an external alarm is installed above the sealed electromagnetic suction door, the external alarm being fixedly connected to the outer surface of the main body of the temporary storage cabinet.

[0017] Preferably, a power distribution cabinet is fixedly connected to the outer surface of the main body of the temporary storage cabinet, and a ladder is fixedly connected to the outer surface of the main body of the temporary storage cabinet on one side of the power distribution cabinet.

[0018] This utility model provides an outdoor hazardous materials storage cabinet, which has the following advantages:

[0019] (1) This utility model uses a conical drainage channel to guide the leaking liquid into the interior of the anti-seepage tray. The bottom area of ​​the conical drainage channel is smaller than the area of ​​the anti-seepage tray, so the probability of the leaking liquid overflowing is reduced. When the distance between the leak point and the inner wall of the main body of the temporary storage cabinet is relatively close, the conical drainage channel can guide the liquid into the interior of the anti-seepage tray, reducing the probability of the leaking liquid flowing along the edge of the gap of the placement rack to the ground of the main body of the temporary storage cabinet, thereby reducing the probability of the ground of the main body of the temporary storage cabinet being contaminated when the liquid leaks.

[0020] (2) This utility model monitors the gas concentration inside the main body of the temporary storage frame by using multiple gas concentration detectors inside the main body of the temporary storage frame. When the concentration of combustible gas inside the main body of the temporary storage frame is high, the ventilation fan is activated to reduce the concentration of combustible gas. At the same time, the liquid nitrogen inerting system can be activated to quickly release nitrogen, so that the nitrogen concentration inside the main body of the temporary storage cabinet can be rapidly increased, thereby reducing the oxygen inside, thus making the main body of the temporary storage cabinet have strong explosion-proof performance.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] The present invention provides a technical solution: (Refer to...) Figure 1-5 In this embodiment, an outdoor hazardous materials storage cabinet includes: a storage cabinet body 1, with two partition plates 101 fixedly connected inside the storage cabinet body 1. The partition plates 101 divide the storage cabinet body 1 into a liquid area 5, a solid area 6, and an emergency area 7. The liquid area 5 mainly holds waste liquid, the solid area 6 mainly holds solid waste, and the solid waste needs to be separated from the liquid before being placed inside the solid area 6. The emergency area 7 is mainly used to store emergency instruments.

[0029] The liquid storage rack 501 is fixedly connected to the inner wall of the temporary storage cabinet body 1. The liquid storage rack 501 has a through hole, and the liquid leaking from the storage tank leaks out through the hole. A sealed tank filled with waste liquid is placed on top of the liquid storage rack 501.

[0030] The conical drainage channel 502 is fixedly connected to the bottom of the liquid storage rack 501. The conical drainage channel 502 is wide at the top and narrow at the bottom and is used to drain the leakage of the storage tank.

[0031] The seepage-proof tray 503 is fixedly connected to the inner wall of the temporary storage cabinet body 1. The seepage-proof tray 503 is made of HDPE material and is located directly below the conical drainage channel 502. The output end area of ​​the conical drainage channel 502 is smaller than the top area of ​​the seepage-proof tray 503.

[0032] An overflow collection tank 505 is installed on the outside of the main body 1 of the temporary storage cabinet. When installing the overflow collection tank 505, its installation height should be slightly lower than that of the seepage prevention tray 503, so that the liquid inside the seepage prevention tray 503 can move to the inside of the overflow collection tank 505 by gravity. A drainage pipe 504 is connected between the overflow collection tank 505 and the seepage prevention tray 503. A safety one-way valve 507 is installed inside the drainage pipe 504. The safety one-way valve 507 effectively prevents the liquid inside the overflow collection tank 505 from flowing back into the seepage prevention tray 503.

[0033] The cavity inside the seepage-proof tray 503 is conical, and the bottom of the seepage-proof tray 503 is also inclined at about 10 degrees, so that the liquid at the bottom of the seepage-proof tray 503 can also be collected at the inlet of the drainage pipe 504 by gravity. The lowest point of the seepage-proof tray 503 is connected to the drainage pipe 504, which is inclined at 30 degrees, so that the liquid can be drained into the overflow collection tank 505 through the drainage pipe 504.

[0034] The height of the overflow collection tank 505 is slightly lower than that of the anti-seepage tray 503. A guide pipe 506 is installed inside the overflow collection tank 505. The output end of the guide pipe 506 is connected to an external drive mechanism. When there is too much liquid inside the overflow collection tank 505, the user can drive the external drive mechanism to transfer the liquid inside the overflow collection tank 505.

[0035] The solid area 6 is equipped with an object placement rack 601. The object placement rack 601 is made of anti-static material and is a removable PP partition with a thickness of about 50mm.

[0036] An explosion-proof suction pump 701 is installed inside the emergency zone 7. The explosion-proof suction pump 701 can centrally absorb the gas from each location. For example, if a liquid leaks from a sealed container, the explosion-proof suction pump 701 can move its nozzle to the side of the leaking sealed container to absorb the volatile gas from the leak. One end of the explosion-proof suction pump 701 extends through the main body of the temporary storage cabinet 1 to the outside of the main body of the temporary storage cabinet 1. A liquid nitrogen inerting system 702 is installed inside the emergency zone 7 near the explosion-proof suction pump 701. The liquid nitrogen inerting system 702 can quickly convert liquid nitrogen into nitrogen gas and release it, thereby rapidly reducing the oxygen concentration inside the main body of the temporary storage cabinet 1.

[0037] The bottom of the main body 1 of the temporary storage cabinet is fixedly connected to a mezzanine base plate 102. A sensing device is installed in the middle of the mezzanine base plate 102. When liquid leaks into the interior of the main body 1 of the temporary storage cabinet, the sensing device can detect it in time and issue an alert. The interior of the main body 1 of the temporary storage cabinet is rotatably connected to a sealed electromagnetic suction door 2. A facial recognition device 201 is installed on the outer surface of the sealed electromagnetic suction door 2. After the facial recognition device 201 successfully recognizes the face, the sealed electromagnetic suction door 2 will automatically open. An external alarm 9 is installed above the sealed electromagnetic suction door 2. The external alarm 9 is fixedly connected to the outer surface of the main body 1 of the temporary storage cabinet. When an abnormal situation occurs inside the main body 1 of the temporary storage cabinet, the external alarm 9 will flash and beep to alert the user.

[0038] Gas concentration detectors 8 are fixedly connected to the inner walls of each partition inside the main body 1 of the temporary storage cabinet. The gas concentration detectors 8 can monitor the concentration of flammable gas inside the main body 1 of the temporary storage cabinet in real time. A ventilation fan 802 is installed on one side of the gas concentration detector 8. In addition to rapid ventilation when the concentration of flammable gas is too high, the ventilation fan 802 will also automatically ventilate at regular intervals, with an approximate frequency of ≥15 ventilations per hour. The connecting pipe on the outer surface of the ventilation fan 802 passes through the main body 1 of the temporary storage cabinet and is fixedly connected to the end face of a one-way safety valve 803. The one-way safety valve 803 can prevent the flammable gas inside the main body 1 of the temporary storage cabinet from overflowing. A sunshade plate 801 is fixedly connected to the outer surface of the ventilation fan 802.

[0039] A power distribution cabinet 3 is fixedly connected to the outer surface of the main body 1 of the temporary storage cabinet. A ladder 4 is fixedly connected to the outer surface of the main body 1 of the temporary storage cabinet on one side of the power distribution cabinet 3. The ladder 4 makes it convenient for users to climb to the top of the main body 1 of the temporary storage cabinet, thereby making it convenient for users to maintain the ventilation fan 802 and other mechanisms on the top of the main body 1 of the temporary storage cabinet.

[0040] This utility model provides an outdoor hazardous materials temporary storage cabinet, the specific working principle of which is as follows:

[0041] When the temporary storage cabinet is constructed, it is assembled using shipping containers. To ensure airtightness, a standard 40-foot shipping container (6058×2438×2591mm) is typically used as the basic frame. The material is 316L stainless steel with a thickness of ≥6mm, and internal welded reinforcing ribs form an explosion-proof structure with a burst pressure of ≥21kPa. During installation, a liquid sensor is installed inside the bottom mezzanine plate 102 to detect any liquid seepage or leakage. Then, a partition plate 101 is installed inside to divide the internal space into zones. After the partitioning is completed, the corresponding instruments and structures are installed in the designated areas.

[0042] When liquid leaks, it flows out from inside the tank and onto the surface of the object placement rack 601. The bottom of the object placement rack 601 is equipped with a conical drainage channel 502, which guides the leaking liquid into the interior of the leak-proof tray 503. The bottom area of ​​the conical drainage channel 502 is smaller than the area of ​​the leak-proof tray 503, and the conical drainage channel 502 effectively diverts the leaking liquid. Therefore, even when the leak point is close to the inner wall of the temporary storage cabinet body 1, the liquid can still enter the leak-proof tray 503 through the conical drainage channel 502. The internal structure reduces the probability of liquid leaking down the object placement rack 601 and flowing along the edge of the gap to the ground of the temporary storage cabinet body 1, thereby reducing the probability of the ground of the temporary storage cabinet body 1 being contaminated when leaking. When the amount of leakage exceeds the quantitative limit, the safety check valve 507 will be activated, allowing the liquid to flow into the overflow collection tank 505. The overflow collection tank 505 has an internal capacity of 200L, which can handle most leakage situations. When the overflow collection tank 505 reaches the rated capacity, the external drive device will be activated to extract liquid from the inside of the overflow collection tank 505.

[0043] When the liquid leaks and evaporates, causing the content of flammable liquid inside the main body 1 of the temporary storage cabinet to be too high, the liquid nitrogen inerting system 702 can be activated to quickly release nitrogen and reduce the oxygen content, thereby achieving the effect of explosion prevention. At the same time, the explosion-proof suction pump 701 can also adjust the air pressure inside the main body 1 of the temporary storage cabinet to reduce the probability of explosion inside the main body 1 of the temporary storage cabinet.

[0044] In normal operation, the gas concentration detector 8 monitors the concentration of flammable gas inside the temporary storage cabinet body 1 in real time. When the concentration of flammable gas is high, the ventilation fan 802 can be activated to pump air, reduce the concentration of flammable gas inside the temporary storage cabinet body 1, and reduce the possibility of explosion of the temporary storage cabinet body 1.

[0045] When opening the temporary storage cabinet, facial recognition is required via facial recognition device 201. Only after successful recognition can the sealed electromagnetic door 2 be opened. An external alarm 9 is installed on one side of the sealed electromagnetic door 2. If any abnormal situation occurs inside the main body of the temporary storage cabinet 1, the external alarm 9 will be triggered to remind staff to take appropriate measures.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
