Description

Technical Field

[0001] This utility model relates to the field of chemical material storage, and in particular to a crystallization raw material storage device. Background Technology

[0002] Currently, in fields such as chemical engineering, pharmaceuticals, and materials science, the storage quality of crystalline raw materials plays a crucial role in subsequent production and product performance. Traditional crystalline raw material storage devices are mostly ordinary sealed containers, which can only provide basic physical isolation and are difficult to meet the stringent requirements of the storage environment.

[0003] Oxygen in the air can react with many crystalline raw materials through oxidation, leading to their deterioration. For example, in organic synthesis, crystalline raw materials with reducing groups undergo changes in molecular structure upon contact with oxygen, affecting the yield and purity of subsequent chemical reactions. Simultaneously, moisture in the environment easily causes crystalline raw materials to deliquesce, especially for highly hygroscopic inorganic salts. Once exposed to moisture, they not only change their physical form but may also trigger chemical reactions, reducing the quality of the raw materials.

[0004] Meanwhile, temperature is also a crucial factor. In the pharmaceutical industry, some bioactive crystalline raw materials are extremely sensitive to temperature; excessively high temperatures can lead to the deactivation of their active ingredients. Furthermore, some low-melting-point crystalline raw materials may melt or clump together at high temperatures. At low temperatures, certain crystalline raw materials may undergo crystal transformation, affecting product quality and stability. Existing storage devices often lack effective temperature control methods or can only achieve a single heating or cooling function, failing to precisely control storage temperature according to the characteristics of different crystalline raw materials.

[0005] In addition, ordinary storage devices are not good at sealing, making it difficult to completely prevent the intrusion of outside air and unable to create a vacuum storage environment, which further weakens the protection of the crystallizing raw materials. Summary of the Invention

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4As shown, this embodiment of the utility model provides a crystallization raw material storage device, including a base 1, with casters 2 fixedly connected to the four corners of the bottom of the base 1, an insulated box 3 fixedly connected to the top of the base 1, an insulation cavity 4 opened on the top of the insulation box 3, a storage tank 5 with heat conduction function fixedly connected inside the insulation cavity 4, and heat conduction oil filling the space between the insulation cavity 4 and the storage tank 5, a sealing cover 6 fixedly connected to the top of the insulation box 3, and the sealing cover 6 is sealed to the insulation box 3, with a feed pipe 7 connected to the top of the sealing cover 6, and a vacuum pump 8 connected to the top of the sealing cover 6, and several vertically evenly arranged heat equalization pipes 9 fixedly connected to the surface of the storage tank 5, and a connection port opened on one side of the bottom of the insulation box 3 for connecting... A connecting frame 10 is fixedly connected inside the opening. A heat exchange block 11 is fixedly connected to the inner side of the connecting frame 10, and the heat exchange block 11 is fixedly connected to the heat dissipation pipe 9. A heat dissipation fin 12 is fixedly connected to the outer side of the heat exchange block 11. Multiple vertically evenly arranged heating pipes 13 are fixedly connected to the inner side of the connecting frame 10, and the heating pipes 13 are fixedly connected to the heat dissipation fins 12. A cooling fan 14 is fixedly connected to the inner wall of the connecting frame 10, and the cooling fan 14 is located outside the heat dissipation fins 12 and does not contact them. A discharge valve 15 is connected to the bottom of the storage tank 5, and a discharge pipe 16 is connected to the output end of the discharge valve 15. A support member is fixedly connected to the outer frame of the cooling fan 14, and the other end of the support member is fixedly connected to the connecting frame 10.

[0020] In practical implementation, the four corner casters 2 of the base 1 facilitate convenient movement of the device, improving equipment flexibility. A storage tank 5 is installed inside the insulation chamber 4 of the insulation box 3, with heat-conducting oil filling the space between them, forming a dual function of insulation and heat conduction. The heat-conducting oil evenly transfers heat, preventing localized overheating or undercooling of the crystallizing raw material in the storage tank 5 and maintaining a stable storage temperature. Meanwhile, the insulation box 3 reduces external temperature interference, improving insulation performance. A sealing cover 6, connected to the insulation box 3, along with the feed pipe 7, achieves sealed storage of the raw material, preventing the intrusion of external impurities. A vacuum pump 8 removes air from the storage tank 5, creating a low-oxygen or vacuum environment, inhibiting oxidation or deliquescence of the raw material and extending the storage period. A heat-spreading pipe 9 is located on the surface of the storage tank 5. The heat exchange block 11 is connected to the heat dissipation fins 12 to form a heat conduction path. When heating is required, the heating tube 13 transfers heat to the heat spreader tube 9 through the heat dissipation fins 12 and the heat exchange block 11, uniformly heating the raw materials in the storage tank 5 and avoiding local crystallization or solidification. When cooling is required, the cooling fan 14 pushes air through the heat dissipation fins 12 to accelerate the heat dissipation of the heat spreader tube 9 and achieve temperature control. The discharge valve 15 and discharge pipe 16 at the bottom of the storage tank 5 facilitate the quantitative discharge of raw materials and are easy to operate. The support fixes the position of the cooling fan 14 to ensure that it maintains a safe distance from the heat dissipation fins 12 and avoids contact wear during operation. At the same time, it also provides an air inlet for the cooling fan 14, thereby ensuring the normal operation of the cooling fan 14.

[0021] refer to Figure 2As shown, several heat spreaders 9 are symmetrically and fixedly connected to heat spreaders 17, and the heat spreaders 17 are fixedly connected to the storage tank 5. By setting the heat spreaders 17, the contact area between the storage tank 5 and the heat spreaders 9 can be increased, the heat conduction efficiency can be enhanced, the temperature distribution inside the storage tank 5 can be made more uniform, and the quality changes caused by local crystallization or uneven temperature of the raw materials can be further prevented.

[0022] refer to Figure 2 As shown, a temperature and humidity sensor 18 is fixedly connected to the bottom of the sealing cover 6, and the temperature and humidity sensor 18 is located inside the storage tank 5 and works in conjunction with it. A control panel 19 is fixedly connected to the top of the sealing cover 6. The temperature and humidity sensor 18 can monitor the temperature and humidity data inside the storage tank 5 in real time, and the data can be displayed or linked to the temperature control system such as the heating element 13 and the cooling fan 14 through the control panel 19, so as to realize the automatic monitoring and adjustment of the storage environment and improve the storage safety and reliability.

[0023] refer to Figure 1 As shown, the ports of the feed pipe 7 and the discharge pipe 16 are threadedly connected to caps 20 with sealing functions. By using the two caps 20, a double seal can be provided when not feeding or discharging, preventing external contaminants such as dust and moisture from entering, while avoiding raw material leakage and ensuring the airtightness and safety of the storage environment.

[0024] refer to Figure 2 As shown, several vertically arranged protective strips 21 are fixedly connected to the outer side of the connecting frame 10, and the protective strips 21 are located outside the cooling fan 14. A dustproof net is fixedly connected to the outermost side of the connecting frame 10. Fixed blocks are symmetrically fixedly connected to both ends of the base 1. A screw rod 22 is threadedly connected to the top of the fixed block. A rotating disk is fixedly connected to the top of the screw rod 22. A brake block 23 is fixedly connected to the bottom of the screw rod 22, and the brake block 23 works in conjunction with the moving wheel 2. The protective strips 21 protect the cooling fan 14 from damage by external impact, improving the durability of the equipment. The dustproof net prevents dust and debris from entering the interior of the connecting frame 10, avoiding dust accumulation on the cooling fins 12 and heating tubes 13, which would affect heat dissipation and heating efficiency. At the same time, it prevents dust from being carried into the storage tank 5 by the cooling fan 14 and contaminating the raw materials. The rotating disc drives the lead screw 22 to rise and fall, causing the brake block 23 to press against or release the moving wheel 2. When the device needs to be fixed, the brake block 23 presses against the moving wheel 2 to prevent the device from sliding. When the device needs to be moved, the brake block 23 is raised to restore the flexibility of the moving wheel 2, thus adapting to different usage scenarios and improving operational convenience and stability.

[0025] The working principle of the crystallization raw material storage device provided by this utility model is as follows: When using the crystallization raw material storage device, the device is first moved by the moving wheels 2 at the bottom of the base 1. At this time, the heat insulation chamber 4 of the heat insulation box 3 at the top of the base 1 is filled with heat-conducting oil on the outside of the storage tank 5. The heat-conducting oil evenly transfers heat to maintain the temperature stability inside the storage tank 5. The sealing cover 6 at the top of the heat insulation box 3 is sealed to the heat insulation box 3. The feed pipe 7 at the top of the sealing cover 6 is used for feeding. Then, the air inside the storage tank 5 can be removed by the vacuum pump 8, so that the inside of the storage tank 5 forms a low-oxygen or vacuum environment to inhibit the oxidation and deliquescence of the raw material. The heat exchange pipe 9 on the surface of the storage tank 5 is connected to the outer heat dissipation fins 12 through the heat exchange block 11 in the connecting frame 10. At this time, the temperature and humidity sensor 18 at the bottom of the sealing cover 6 monitors the temperature and humidity inside the storage tank 5 and displays or adjusts it through the top control panel 19. When the storage tank 5 needs to be heated, the heating tube 13 transfers heat to the heat exchanger 9 through the heat dissipation fins 12 and the heat exchange block 11, so as to evenly heat the raw materials in the storage tank 5 and avoid local crystallization or solidification. Conversely, when cooling it, the heat dissipation fan 14 on the inner wall of the connecting frame 10 pushes the air to flow through the heat dissipation fins 12 to accelerate the heat dissipation of the heat exchanger 9 and achieve cooling, thereby realizing the temperature control of the crystalline raw materials. At this time, the heat exchanger plate 17 on the surface of the heat exchanger 9 increases the contact area to enhance heat conduction. The discharge valve 15 and discharge pipe 16 at the bottom of the storage tank 5 are used for raw material discharge. The port caps 20 of the feed pipe 7 and discharge pipe 16 ensure sealing. The outer protective strip 21 of the connecting frame 10 protects the heat dissipation fan 14 and the outermost dustproof net protects against dust. The screw rod 22 on the fixing blocks at both ends of the base 1 drives the brake block 23 to rise and fall through the rotating disk to brake or unlock the moving wheel 2.
