Description

Technical Field

[0001] The utility model relates to the field of cold storage for storing medicines, in particular to a cold storage for storing medicines. Background Art

[0002] Pharmaceutical cold storage facilities are specially designed to store pharmaceuticals, ensuring they are kept at optimal temperature and humidity to maintain their effectiveness and safety. These cold storage facilities are typically equipped with advanced temperature and humidity control systems to maintain consistent environmental conditions, preventing pharmaceutical spoilage due to temperature fluctuations. The interior structure of these cold storage facilities is typically constructed of materials that are easy to clean and disinfect to prevent microbial contamination. Furthermore, these cold storage facilities feature excellent thermal insulation to reduce energy consumption and maintain a stable internal environment. Pharmaceutical cold storage facilities are widely used in hospitals, pharmaceutical factories, wholesalers, and retail pharmacies.

[0003] In the current pharmaceutical storage sector, cold storage is a common storage facility, often used to ensure medications are kept at optimal temperatures. However, in practice, most cold storage facilities utilize a single-layer structure to store medications. This single-layer storage method has certain limitations in terms of efficiency.

[0004] Specifically, while single-layer cold storage can meet basic temperature control needs, its space utilization is suboptimal. Because medications typically need to be stored within a specific temperature range, single-layer cold storage often lacks the flexibility to accommodate diverse medication storage requirements. Furthermore, single-layer cold storage also wastes space, as it fails to fully utilize vertical space.

[0005] In contrast, a double-layer storage structure can theoretically improve space utilization and thus storage efficiency. However, in practice, the design and use of double-layer cold storage also face some challenges. In particular, the presence of a partition within a double-layer cold storage can hinder the flow rate of cold air. This slowed flow of cold air can lead to uneven temperature distribution within the cold storage, which in turn affects the preservation of medications. Utility Model Content

[0006] The main purpose of the utility model is to provide a cold storage for storing medicines, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A cold storage for storing medicines, comprising a cold storage room, an isolation layer, a mounting frame, a refrigeration cycle unit, and a control cabinet. The isolation layer is placed in the middle section of the cold storage room. The refrigeration cycle unit and the control cabinet are mounted on the outer end of the cold storage room via the mounting frame. The refrigeration cycle operation of the refrigeration cycle unit is controlled by the control cabinet.

[0009] The isolation layer is provided with ventilation holes, which reduce the flow rate of the upper and lower cavities of the isolation layer. A plurality of medicine storage racks are placed at the ventilation holes of the isolation layer, and the medicines are stored through the medicine storage racks.

[0010] A serpentine pipe is provided inside the isolation layer, and a plurality of nozzles are provided at the lower end of the serpentine pipe. The inlet of the serpentine pipe is connected to the air intake pipe, which is connected to the refrigeration cycle unit through the air intake pipe. The outlet of the serpentine pipe is connected to the return air pipe, which is connected to the refrigeration cycle unit through the return air pipe. The nozzle sprays out cold air and then realizes the rapid flow of cold air through the air holes.

[0011] As a preferred embodiment of the present application, the serpentine pipe is laid flat in the inner cavity of the isolation layer, the serpentine pipe is connected to the nozzle through a threaded pipe, and the serpentine pipe is connected to the air inlet pipe and the air return pipe through a connecting flange, bolts, and nuts;

[0012] As a preferred solution of the present application, a plurality of the nozzles are equidistantly distributed on the serpentine pipe, and a plurality of the nozzles are located at the air holes, and an "I"-shaped pipe is installed at the air holes;

[0013] As a preferred solution of the present application, the return air duct and the intake air duct are connected to the intake port and the return port of the refrigeration cycle unit through connecting flanges, bolts, and nuts, and the refrigeration cycle unit is fixed to the mounting frame by bolts;

[0014] As a preferred solution of the present application, the control cabinet is fixed to the mounting frame by bolts, and the refrigeration cycle unit includes a compressor, a condenser, an expansion valve, an evaporator and an insulation pipe;

[0015] As a preferred solution of the present application, an electric-controlled valve is installed on each of the air jet heads, and the electric-controlled valve is connected to the control cabinet through a wire passing through the cold storage room.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Through carefully designed insulation layers and serpentine nozzles, we ensure uniform and stable temperature and humidity distribution within the cold storage. This design fully meets the stringent environmental requirements for pharmaceutical storage, ensuring the safety and effectiveness of drugs during storage. The insulation layers and ventilation holes not only accelerate the flow rate between chambers, but also effectively prevent drug damage caused by environmental fluctuations. By precisely controlling the refrigeration cycle, we successfully avoid energy waste and achieve efficient operation of the cold storage facility.

[0018] The user-friendly layout of the refrigeration cycle unit and control cabinet facilitates daily operation and maintenance, significantly improving work efficiency. By remotely controlling the on / off switch of the air jets and the opening of the electronically controlled valves through the control cabinet, we achieve precise regulation of the temperature and humidity inside the cold storage, greatly improving operational convenience and accuracy. The optimized mounting method for the control cabinet and mounting bracket ensures equipment stability and reliability, minimizing the possibility of equipment failure and further enhancing operational efficiency and safety.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, a cold storage facility for storing medicines is mainly composed of the following key components: a cold storage room 1, an isolation layer 2, a mounting frame 5, a refrigeration cycle unit 6, and a control cabinet 7. Among them, the isolation layer 2 is carefully designed and located in the middle of the interior of the cold storage room 1. Its main purpose is to ensure that the temperature and humidity inside the cold storage can be effectively controlled and regulated. The refrigeration cycle unit 6 and the control cabinet 7 are cleverly installed at the outer end of the cold storage room 1 via the mounting frame 5. This layout not only facilitates the operator's daily operation and maintenance work, but also ensures the stable operation of the equipment.

[0026] The main function of the control cabinet 7 is to control the refrigeration cycle operation of the refrigeration cycle unit 6. Through precise control, the temperature and humidity inside the cold storage are always maintained within the appropriate range to meet the special needs of drug storage. The isolation layer 2 is provided with multiple ventilation holes 3. These holes function to accelerate the flow rate between the upper and lower cavities of the isolation layer 2, thereby maintaining stable temperature and humidity. Multiple drug storage racks 4 are placed in the ventilation holes 3. These racks are specifically designed for storing drugs. These racks not only facilitate drug management and access, but also ensure the safety and effectiveness of drugs during storage.

[0027] Inside the insulation layer 2, a serpentine duct 9 is also installed. Multiple nozzles 10 are connected to the lower end of the duct to discharge cold air. The inlet of the serpentine duct 9 is connected to the refrigeration cycle unit 6 via the air inlet duct 8, while the outlet is connected to the refrigeration cycle unit 6 via the air return duct 11, forming a complete refrigeration cycle system. The nozzles 10 are evenly distributed along the serpentine duct 9, ensuring uniform discharge of cold air, thereby maintaining the ideal temperature and humidity within the cold storage.

[0028] Air holes 3 are fitted with "I"-shaped ducts to further optimize the flow of cold air. The return air duct 11 and the intake air duct 8 are connected to the air inlet and return ports of the refrigeration cycle unit 6 via flanges, bolts, and nuts, ensuring proper operation of the refrigeration cycle unit 6. The refrigeration cycle unit 6 comprises a compressor, condenser, expansion valve, evaporator, and insulated piping. These components work together to ensure ideal temperature and humidity within the cold storage.

[0029] Each air jet 10 is equipped with an electrically controlled valve, which is connected to the control cabinet 7 via wires running through the cold storage room 1. Through the control cabinet 7, an operator can remotely control the opening and closing of each air jet 10, thereby precisely adjusting the temperature and humidity inside the cold storage. The control cabinet 7 is secured to the mounting frame 5 with bolts, ensuring its stability and reliability. The design of the entire cold storage facility fully considers the special needs of pharmaceutical storage. Through a scientific and rational layout and advanced equipment, the safety and effectiveness of pharmaceuticals during storage are guaranteed.

[0030] Usage process: Turn on the power switch of the control cabinet 7. Make sure that the power of the refrigeration cycle unit 6 is connected. Set the required temperature and humidity parameters on the control panel of the control cabinet 7. These parameters should meet the standard requirements for drug storage. Confirm that all components (such as compressors, condensers, expansion valves and evaporators) are operating normally. Check whether the insulation pipes are intact to ensure that the cold air does not leak. Remotely control the switch of each nozzle 10 through the control cabinet 7. Adjust the opening of the electric control valve as needed to evenly spray cold air. Regularly monitor the temperature and humidity inside the cold storage to ensure that they remain within the set range. If there is any deviation, adjust the working status of the refrigeration cycle unit 6 through the control cabinet 7. Regularly maintain and inspect the equipment to ensure its normal operation. Clean the filter and check the refrigerant charge.

[0031] Control Process: Temperature and humidity sensors within cold storage room 1 monitor environmental data in real time. The sensors transmit this data to the control system in control cabinet 7. The control system in control cabinet 7 receives the sensor data and compares it with the set temperature and humidity parameters. Based on the comparison results, the system calculates the required cooling capacity and the opening degree of the air purifier 10. Control cabinet 7 sends control signals to the refrigeration cycle unit 6 to adjust the operating status of the compressor, condenser, expansion valve, and evaporator. Control cabinet 7 sends control signals via wires to the electronically controlled valves of each air purifier 10 to adjust their opening degrees. Control cabinet 7 receives real-time sensor feedback and continuously adjusts the control signals. If the temperature and humidity deviate from the set range, the system automatically adjusts the operating status of the refrigeration cycle unit 6 and the air purifier 10 to restore them to the set parameters. If the system detects an abnormality (such as equipment failure or temperature or humidity exceeding the safe range), control cabinet 7 issues an alarm. The system automatically takes protective measures, shutting down the refrigeration cycle unit 6 to ensure the safety of the equipment and pharmaceuticals.
