Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, and in particular to a low-temperature chemical hazardous reagent storage cabinet. Background Technology

[0002] The safe storage of hazardous chemical reagents is a core requirement in the chemical, pharmaceutical, and scientific research fields. These reagents typically possess properties such as flammability, explosiveness, corrosivity, or high reactivity. Some reagents (such as certain enzyme preparations, biological samples, and low-temperature stable chemicals) also require storage in strictly controlled low-temperature environments to prevent decomposition, volatilization, or uncontrollable reactions.

[0003] Most existing storage facilities for hazardous chemicals are fixed designs, non-removable, and bulky (generally exceeding 1.5m). 3 However, these storage cabinets only have simple support legs at the bottom, requiring forklifts or multiple people to move them, resulting in high labor intensity and low efficiency. Some storage cabinets equipped with wheels lack locking mechanisms or components, making them susceptible to tipping over due to the lack of proper locking, posing a significant potential safety hazard. Furthermore, existing chemical hazardous materials storage cabinets often use shelves or open racks to hold reagent bottles, lacking specific securing designs. Placing reagents directly on shelves or racks easily leads to misalignment and inconvenience. Additionally, for reagent bottles requiring low-temperature storage, the plastic or metal shelves are prone to brittle deformation at low temperatures, and the bottles are easily shaken and slip, also posing a high safety risk.

[0004] Meanwhile, for small and medium-sized enterprises that use hazardous chemical reagents, using large-scale hazardous chemical storage equipment not only results in high production costs but also in ineffective utilization, leading to low utilization rates and resource waste. Furthermore, it cannot meet the need for relocation during use. Therefore, there is an urgent need to design a low-temperature hazardous chemical reagent storage cabinet suitable for small and medium-sized enterprises. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a low-temperature chemical hazardous reagent storage cabinet.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A low-temperature chemical hazardous material reagent storage cabinet includes a storage cabinet body, an equipment placement cabinet, a support, a cabinet door, and a reagent placement platform. The storage cabinet body and equipment placement cabinet are both vertically oriented. The storage cabinet body is hollow with an opening on one longitudinal side.

The absorber can absorb heat from the cavity.

[0013] The equipment placement cabinet includes an outer shell, a cooling device, and a shock absorption device. The outer shell is vertically oriented and protects the internal equipment. The interior of the outer shell is hollow, and both the cooling device and the shock absorption device are located inside the hollow interior. The input end of the cooling device is connected to a second integrated module via a water pipe, and the output end is connected to a first integrated module via a water pipe. The cooling device can cool the cooling water. The upper surface of the shock absorption device is connected to the lower surface of the cooling device, and the lower surface of the shock absorption device is connected to the lower surface of the hollow interior of the outer shell. The shock absorption device can absorb vibrations generated by the cooling device during operation.

[0014] The reagent placement table includes a reagent placement table body and engaging protrusions. The reagent placement table body is arranged horizontally, and the engaging protrusions are arranged vertically. The horizontal ends of the reagent placement table body protrude outward to form engaging protrusions, which are matched with the slots of the storage cabinet body. The engaging protrusions can be detachably engaged in the slots. Multiple reagent placement slots are evenly distributed and spaced along the horizontal direction on the reagent placement table body. The reagent placement slots are recessed downward from the upper surface of the reagent placement table body, and reagents to be placed can be detachably placed on the reagent placement slots.

[0015] Furthermore, the support includes a support body, a limiter, a rotating wheel, a limiter handle, and a limit groove. The support body is arranged in a vertical direction, and a rotating wheel is installed at the bottom of the support body.

[0016] The limiter is slidably connected to the side surface of the bottom of the support body. The bottom of the limiter is matched with the size of the wheel. When the limiter is in contact with the ground, it can tightly engage the wheel and prevent it from rotating. The upper part of the part where the support body and the limiter are connected is provided with a limit groove. The limit groove is set in the vertical direction. The limiter handle passes through the limit groove and is tightly connected to the limiter. The limiter handle can move up and down in the limit groove. When the limiter moves downward in the vertical direction, it can tightly engage the movement of the wheel.

[0017] Furthermore, the cabinet door includes a cabinet door body, a cabinet door handle, and a temperature display. A temperature sensor is installed inside the protective cover of the second integrated module.

[0019] Furthermore, the outer shell of the storage cabinet, the outer shell of the equipment placement cabinet, and the cabinet door are all made of explosion-proof and corrosion-resistant materials.

[0020] Furthermore, the depth of the reagent placement slot of the reagent placement rack is set to one-third of the reagent bottle's depth.

[0021] The advantages and positive effects of this utility model are as follows:

[0022] 1. In use, first connect the power supply, turn on the cooling device in the equipment cabinet, and start the circulating water system. Cooling water enters the heat absorber through the first integrated module, absorbs heat from the cavity, and then returns to the cooling device through the second integrated module to cool down, forming a closed-loop circulation until the cavity reaches the preset low temperature. Then, pull the cabinet door to open it, and vertically insert the reagent bottle into the reagent placement slot on the reagent placement platform, ensuring that the locking protrusions are tightly engaged with the slots inside the storage cabinet to prevent slippage. Finally, close the cabinet door to ensure a tight seal.

[0023] This invention utilizes a heat absorber and a closed-loop water-cooling system to rapidly cool and maintain a low temperature within the chamber, making it suitable for temperature-sensitive chemical reagents. A shock-absorbing device effectively absorbs vibrations from the cooling system, preventing collisions between reagent bottles caused by vibrations during operation. The storage cabinet body, equipment placement cabinet, and supports are modularly connected, facilitating disassembly, maintenance, and functional expansion, thus extending the equipment's lifespan. The slots and reagent racks allow for flexible placement of different hazardous materials, ensuring storage safety and facilitating easy access to reagents.

[0024] 2. This utility model effectively absorbs the vibration of the cooling device through a shock absorption device, preventing collisions between reagent bottles caused by vibrations generated during the operation of the cooling device. The engagement of the locking protrusion and the locking groove allows the reagent placement platform to be inserted into the storage cabinet without falling off or shaking. The reagent placement groove provides a placement position for the reagents, ensuring that the reagents remain vertical and preventing tilting and leakage.

[0025] 3. This invention utilizes a heat absorber and a closed-loop water-cooling system to rapidly cool and maintain a constant temperature within the cavity, making it suitable for temperature-sensitive chemical reagents.

Unless otherwise specified, all methods used in this invention are conventional methods in the field. The quantities of all substances used in this invention are conventional usage quantities. Structures and connections not described in detail in this invention can be understood as conventional technical means in the field.

[0038] A low-temperature chemical hazardous reagent storage cabinet, such as Figure 1 and Figure 9 As shown, the reagent storage cabinet includes a storage cabinet body 1, an equipment placement cabinet 2, a support 3, a cabinet door 4, and a reagent placement platform 5. The storage cabinet body and equipment placement cabinet are both vertically oriented. The storage cabinet body is hollow inside with an opening on one longitudinal side. The reagent placement platform is horizontally oriented and can be detachably installed inside the storage cabinet body. Reagents to be stored can be detachably installed on the platform. The equipment placement cabinet is connected to and located below the storage cabinet body, and cooling equipment can be placed inside. The support is connected to and located below the equipment placement cabinet. The storage cabinet body can be moved and locked via the support, which also provides support for the reagent storage cabinet body. Several supports are evenly distributed circumferentially on the lower surface of the equipment placement cabinet. The cabinet door is vertically oriented and hinged to the opening on one longitudinal side of the storage cabinet body. The cabinet door can open and close the opening on one side of the storage cabinet body, thus allowing the storage cabinet body to be opened and closed.

[0039] In this invention, the storage cabinet body provides space for the reagent rack, the cooling device inside the cabinet provides cooling for the storage cabinet body, so that the reagents on the rack can preserve chemicals that require low-temperature storage, and the support provides support for the storage cabinet body and can be moved, so that the storage cabinet can be moved easily, reducing manpower, facilitating transportation and improving efficiency.

[0040] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the storage cabinet body includes a storage cabinet body shell 1-1, a slot 1-2, a first integrated module 1-3, a heat absorber 1-4, a water pipe 1-5, and a second integrated module 1-6. The storage cabinet body shell is arranged vertically and is hollow inside with an opening on one side. The hollow interior forms a cavity 1-7. The cabinet door is hinged to the opening side of the storage cabinet body. The slot, the first integrated module, the heat absorber, the water pipe, and the second integrated module are all located inside the cavity. The inner wall of the storage cabinet body shell is symmetrically arranged with slot groups along the horizontal direction. The slot groups are arranged vertically, and each slot group includes multiple slots evenly distributed and spaced along the vertical direction. The slots are arranged longitudinally, and two slots facing each other in the horizontal direction can be detachably engaged to install a reagent placement table, so that the reagent placement table can be suspended inside the cavity without falling off. The storage cabinet body shell can protect the devices inside the cavity, so that the reagents inside the cavity are not affected by the external environment.

[0041] Both the first integrated module and the second integrated module include a water solenoid valve (not shown in the figure) and a protective cover (not shown in the figure). The protective cover is disposed outside the water solenoid valve. The protective cover can protect the water solenoid valve and provide protection for the wiring, and prevent it from being corroded by hazardous materials, thus maintaining the stable operation of the device.

[0042] The horizontal surface of the first integrated module is connected to the horizontal surface of the inner wall of the storage cabinet shell inside the cavity. The lower surface of the first integrated module is connected to the lower bottom surface of the inner wall of the storage cabinet shell inside the cavity. The longitudinal outer surface of the first integrated module is on the same plane as the longitudinal outer surface of the storage cabinet shell. The heat absorber is arranged in a horizontal direction and is connected to the inner wall of the storage cabinet shell at the top of the cavity.

[0043] The horizontal surface of the second integrated module is connected to the horizontal surface of the inner wall of the storage cabinet body shell inside the cavity. The lower surface of the second integrated module is connected to the lower bottom surface of the inner wall of the storage cabinet body shell inside the cavity. The longitudinal outer surface of the second integrated module is on the same plane as the longitudinal outer surface of the storage cabinet body shell.

[0044] The water solenoid valve in the first integrated module is connected to one port of the heat absorber via a water pipe, and the water solenoid valve in the second integrated module is connected to the other port of the heat absorber via a water pipe. The first integrated module can deliver cooling water from the equipment placement cabinet to the water pipe, and the second integrated module can deliver cooling water from the water pipe to the equipment placement cabinet, allowing the cooling water to circulate and cool inside the cavity, improving cooling efficiency and maintaining a low-temperature environment. Cooling water can be introduced into the water pipe, delivered to the heat absorber, and the cooled water after heat absorption in the heat absorber can be output from the heat absorber. The heat absorber can absorb heat inside the cavity, lowering the temperature inside the cavity and enabling some hazardous materials to meet the low-temperature storage requirements. The use of the water solenoid valve can also make full use of the cooling water by adjusting the opening and closing time of the water solenoid valve, improving utilization rate.

[0045] like Figure 5 As shown, the equipment storage cabinet includes an outer shell 2-1, a cooling device 2-2, and a shock-absorbing device 2-3. The outer shell is vertically oriented and protects the internal equipment from external environmental influences. The interior of the outer shell is hollow, with both the cooling device and the shock-absorbing device housed within it. The input of the cooling device is connected to the second integrated module via a water pipe 2-4, and the output is connected to the first integrated module via a water pipe. The cooling device cools the water. The upper surface of the shock-absorbing device is connected to the lower surface of the cooling device, and the lower surface of the shock-absorbing device is connected to the lower surface of the hollow interior of the outer shell. The shock-absorbing device dampens the vibrations generated by the cooling device during operation, reducing their impact on the overall reagent storage cabinet and preventing accidents caused by shaking of the reagents.

[0046] like Figure 9As shown, the reagent placement table includes a reagent placement table body 5-1 and engaging protrusions 5-3. The reagent placement table body is arranged horizontally, and the engaging protrusions are arranged longitudinally. The horizontal ends of the reagent placement table body protrude outward to form engaging protrusions, which are matched with the slots of the storage cabinet body. The engaging protrusions can be detachably engaged in the slots. Through the engaging protrusions and slots, the reagent placement table body can be detachably installed on the outer shell of the storage cabinet body. The cooperation between the engaging protrusions and slots allows the reagent placement table to be inserted into the storage cabinet without falling off or shaking, making installation and disassembly convenient and improving work efficiency. Multiple reagent placement slots 5-2 are evenly distributed and spaced along the horizontal direction on the reagent placement table body. The reagent placement slots are recessed downward from the upper surface of the reagent placement table body. The reagents to be placed can be detachably placed in the reagent placement slots. The arrangement of the reagent placement slots provides a placement position for the reagents, allowing the reagents to be placed stably and preventing tilting and leakage.

[0047] In use, first connect the power supply, turn on the cooling device in the equipment cabinet, and start the circulating water system. Cooling water enters the heat absorber through the first integrated module, absorbs heat from the cavity, and then returns to the cooling device through the second integrated module to cool down, forming a closed-loop circulation until the cavity reaches the preset low temperature. Then, pull the cabinet door to open it, and vertically insert the reagent bottle into the reagent placement slot on the reagent placement platform, ensuring that the locking protrusions are tightly engaged with the slots inside the storage cabinet to prevent slippage. Finally, close the cabinet door to ensure a tight seal.

[0048] This invention utilizes a heat absorber and a closed-loop water-cooling system to rapidly cool and maintain a low temperature within the chamber, making it suitable for temperature-sensitive chemical reagents. A shock-absorbing device effectively absorbs vibrations from the cooling system, preventing collisions between reagent bottles caused by vibrations during operation. The storage cabinet body, equipment placement cabinet, and supports are modularly connected, facilitating disassembly, maintenance, and functional expansion, thus extending the equipment's lifespan. The slots and reagent racks allow for flexible placement of different hazardous materials, ensuring storage safety and facilitating easy access to reagents.

[0049] In this embodiment, as Figure 6 and Figure 7 As shown, the support includes a support body 3-1, a limiter 3-2, a rotating wheel 3-3, a limiter handle 3-4, and a limit groove 3-5. The support body is arranged vertically, and a rotating wheel is installed at the bottom of the support body. The rotating wheel enables the reagent storage cabinet to move, making it easy to move.

[0050] The limiter is slidably connected to the side surface of the bottom of the support body. The bottom of the limiter is matched to the size of the rotating wheel. When the limiter is in contact with the ground, it can tightly engage the rotating wheel, preventing it from rotating. A limit groove is provided at the upper part of the connection between the support body and the limiter. The limit groove is vertically oriented, and the limiter handle passes through the limit groove and is tightly connected to the limiter. The limiter handle can move up and down within the limit groove, allowing it to pull the limiter vertically along the groove. When the limiter moves downwards vertically, it tightly engages the rotating wheel, fixing the reagent storage cabinet body in place. This structure allows for easy movement of the entire device through simple mechanical operation, facilitating relocation according to experimental needs without the need for forklifts or other auxiliary equipment, thus improving work efficiency.

[0051] In this embodiment, as Figure 8 As shown, the cabinet door includes a door body 4-1, a door handle 4-2, and a temperature display 4-3. A temperature sensor (not shown) is installed inside the protective cover of the second integrated module. The door handle is connected to the door body and allows for opening and closing of the door. The temperature display is connected to the door body and is signal-connected to the temperature sensor. The temperature sensor measures the internal temperature of the storage cabinet body, and the temperature display shows the internal temperature of the storage cabinet cavity. This design allows operators to adjust the cooling intensity of the cooling device based on the temperature sensor readings, ensuring the efficiency of the storage cabinet operation. The inclusion of the second integrated module also improves the space utilization efficiency of the equipment.

[0052] Preferably, an electromagnetic switch (not shown in the figure) is provided on the longitudinal outer surface of the first integrated module to match the cabinet door. The electromagnetic switch is located on the outside of the protective cover of the first integrated module, and the cabinet door handle can operate the electromagnetic switch to open and close, thereby further improving the sealing and safety of the reagent storage cabinet body.

[0053] Preferably, the outer shell of the storage cabinet body, the outer shell of the equipment placement cabinet, and the cabinet door body are all made of explosion-proof and corrosion-resistant materials, which reduces the damage to the outer shell caused by hazardous materials inside the cabinet and improves its service life.
