[0002] Multi-temperature quick-freezing equipment is a kind of freezing equipment with multiple independent temperature control sections. It can quickly freeze food or other items in different temperature sections. By controlling the freezing speed and temperature of each temperature section, it can meet the specific freezing requirements of different items, thereby ensuring the quality and taste of the frozen products. Especially in the freezing processing of seafood, meat, fruits and vegetables, etc., multi-temperature quick-freezing equipment can provide precise freezing control according to different food characteristics and freezing requirements to ensure the nutritional value and taste of food. In the low-temperature storage of biological samples, vaccines, medicines, etc., multi-temperature quick-freezing equipment can provide stable Low temperature environment ensures the activity of samples and the effectiveness of drugs. For chemical raw materials and new materials that need low temperature treatment, multi-temperature section quick freezing equipment can also provide suitable freezing conditions. Generally, high-efficiency compressors, refrigerants and other equipment are used to achieve rapid cooling and stable maintenance of different temperature sections, or through sensors and control systems, the temperature of each temperature section is monitored and adjusted in real time to ensure that the temperature is stable and meets the set requirements. The heat exchange structure can also be optimized to improve refrigeration efficiency and reduce energy consumption. The advantages of multi-temperature section quick freezing equipment mainly include the ability to flexibly adjust the number and size of temperature sections according to different items and freezing requirements to meet Meet the diversified production needs or achieve fast and uniform freezing effect through advanced refrigeration system and precise temperature control, improve production efficiency, and precise temperature control and rapid freezing can maintain the nutritional content and taste of food, ensure product quality, and use environmentally friendly materials and energy-saving design to reduce the impact on the environment and reduce operating costs. Therefore, multi-temperature quick-freezing equipment has been widely used in many industries for its flexibility, high efficiency and guarantee of product quality. Generally speaking, traditional quick-freezing equipment is often limited to a single cold source, and it is difficult to achieve precise quick-freezing adjustment in multiple temperature sections, which greatly limits its application in diversified production needs. , so this case aims to break this limitation and hopes to propose a new multi-temperature-stage quick-freezing equipment design, which adopts a single cold source but can simultaneously realize quick-freezing adjustment in multiple temperature stages. It not only overcomes the shortcomings of traditional quick-freezing equipment, but also reduces energy consumption and improves production efficiency through efficient use of cold sources. At the same time, its multi-temperature-stage adjustment function enables the equipment to better adapt to different items and freezing needs, providing a more flexible and efficient freezing solution for multiple industries such as food and medicine. For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above purpose, the utility model is implemented through the following technical solutions: a multi-temperature section quick freezing equipment, comprising: a refrigeration shell, a cold air conduction warehouse, a cold air return pipe and a cold air delivery pipe, the cold air return pipe is installed on the refrigeration shell, the cold air delivery pipe is installed on the cold air conduction warehouse, the refrigeration shell is connected to the cold air conduction warehouse, a refrigeration source circulation structure is installed in the refrigeration shell, and a temperature control section auxiliary wind component is installed in the cold air conduction warehouse;

[0004] The refrigeration source circulation structure includes: a main compressor, a matching condenser, a coordinated liquid storage device, an associated expansion valve, an integrated evaporator, an evaporator carrier, a drying filter, a cold air generation chamber, a condensation ventilation pump, a guide air pipe, a release air pipe, a hot air connection joint and an airway dustproof net;

[0005] The main compressor is installed in the refrigeration shell, and the main compressor is connected to the matching condenser through a pipeline, the matching condenser is installed in the refrigeration shell, and the matching condenser is connected to the coordination accumulator through a pipeline, the coordination accumulator is installed in the refrigeration shell, and the coordination accumulator is connected to the associated expansion valve through a pipeline, the associated expansion valve is installed in the refrigeration shell, and the associated expansion valve is connected to the integrated evaporator through a pipeline, the evaporator carrier is installed in the refrigeration shell, and the integrated evaporator is installed in the evaporator The integrated evaporator is connected to the dry filter through a pipeline, the dry filter is installed in the refrigeration shell, and the dry filter is connected to the main compressor through a pipeline, the cold air generation chamber is provided in the refrigeration shell, the integrated evaporator is connected to the cold air generation chamber, the condensation ventilation pump is installed on the matching condenser, the guide air pipe is inserted in the refrigeration shell, and the guide air pipe is connected to the airway dustproof net, the release air pipe is inserted in the refrigeration shell, and the hot air connection joint is connected to the release air pipe;

[0006] It should be noted that, in the above, the refrigerant enters the main compressor in the refrigeration shell through the pipeline, the refrigerant is compressed into a high-temperature and high-pressure gas, and enters the next item of the matching condenser through the connecting pipeline. The matching condenser cools and condenses the high-temperature and high-pressure gaseous refrigerant through heat exchange with the external environment (such as air or water) into a medium-temperature and high-pressure liquid refrigerant. Before the liquid refrigerant flows into the integrated evaporator, it will first pass through the coordination accumulator. The main function of the coordination accumulator is to store liquid refrigerant and absorb moisture and impurities from the refrigerant to ensure the purity of the refrigerant. After passing through the coordination accumulator, the liquid refrigerant enters the associated expansion valve, whose function is to adjust the flow rate of the refrigerant and pressure, causing the refrigerant to expand into a low-temperature and low-pressure gas-liquid mixture under low pressure. The low-temperature and low-pressure gas-liquid mixture then enters the integrated evaporator, where it absorbs the heat of the air in the cold air generating compartment, causing the refrigerant to completely evaporate into a gaseous state. At the same time, the integrated evaporator releases cold air to achieve a refrigeration effect, cooling the air in the cold air generating compartment, while the condensing ventilation pump draws outside air into the matching condenser through the guide air pipe and the airway dustproof net, thereby taking away the heat released in the matching condenser, and then releasing it to the outside through the release air pipe and the hot air connection joint or guiding it to other places after the bridge pipe. The control instrument arranged on the refrigeration shell can adjust the refrigeration amplitude of the entire equipment.

[0007] Preferably, the temperature control section auxiliary wind power assembly includes: a plurality of partition baffles, a plurality of guide and regulating fans, a partition electromagnetic valve and a cold air suction pump;

[0009] It should be noted that, in the above, the operation of the cold air suction pump will draw the cold air in the cold air generation bin to the cold air return duct and then transport it from the cold air delivery duct to the cold air conduction bin. After that, it will be guided and controlled by PLC (PLC, the full name is programmable logic controller, is a digital operation electronic system designed for use in industrial environments. It uses programmable memory to store and execute logical operations, sequential control, timing, counting and arithmetic operations and other operation instructions, and through digital and analog input and output, it controls various types of machinery or production processes) to guide and control multiple guiding and regulating fans respectively, and selectively drive the corresponding fans according to the temperature in the space after the partition wall is separated, so that the partition wall is divided. The air in the space behind the partition flows in a certain direction or forward direction, thereby controlling the speed at which cold air flows from the cold air delivery pipe into the cold air conduction bin body. (For example, when a pair of guiding and regulating fans installed at the opening of the partition partition are running at the same time, the wind pressure gathers together to form an air vortex, which can stop the flow of gas in the partition partition, thereby achieving the temperature difference between the spaces between the partition partitions, and the temperature gradually increases from the cold air delivery pipe to the temperature of each space of the partition solenoid valve, thereby achieving the effect of multi-temperature stage regulation.) The partition solenoid valve can separate the cold air generation bin and the cold air conduction bin body, which is conducive to better control of the temperature in the equipment space. The storage bin door set on the cold air conduction bin body can place items that need to be quickly frozen into the cold air conduction bin body.

[0012] Preferably, a wind monitor is provided in the cold air conduction compartment;

[0013] Preferably, a storage compartment door is provided on the cold air conduction compartment body.

[0014] Beneficial Effects

[0015] The utility model provides a multi-temperature section quick freezing device. It has the following beneficial effects. Compared with the prior art, the multi-temperature section quick freezing device has the following beneficial effects: the device uses a cooling source circulation structure to enable the various components in the refrigeration shell to work together efficiently, deeply cool the air in the cold air generation bin, and at the same time, through the precise conduction of the temperature control section auxiliary wind power component, the cold air can quickly and evenly enter the cold air conduction bin. In this process, we fully utilize the advantages of a single cold source, and combine the wind pressure regulation technology under the cooperation of multiple guiding and regulating fans to cleverly separate and adjust the temperature of multiple spaces in the cold air conduction bin. In this way, not only the high efficiency of cold air conduction is ensured, but also the space utilization rate of the equipment is significantly improved, so that the device has reached an excellent level in terms of cooling effect and space utilization.
