Description

Technical Field

[0001] This utility model belongs to the technical field of cold storage refrigeration equipment, and in particular, it is an environmentally friendly and energy-saving cold storage refrigeration equipment. Background Technology

[0002] Cold storage facilities are essential for storing food, medicine, and other goods. The core function of cold storage refrigeration equipment is to create and maintain a stable, low-temperature environment inside the cold storage. Through the cyclical operation of the refrigeration unit, heat is continuously transferred from inside the cold storage to the outside, achieving precise temperature control. During use, the air inside the cold storage may contain impurities such as dust, fibers, and debris. Traditional environmentally friendly and energy-saving cold storage refrigeration equipment can meet basic refrigeration needs, but its air inlet filtration capacity is weak. These impurities will enter the refrigeration equipment with the air, accelerating component wear and even causing mechanical failures, affecting the service life and stability of the equipment, and increasing maintenance costs and downtime.

[0003] A search of Chinese patent documents (authorization announcement number CN222598149U) reveals that this utility model uses a movable component to move the refrigeration unit, enabling it to uniformly cool the interior of the cold storage unit and save energy. A lifting component allows the refrigeration unit to be raised and lowered, ensuring it operates only within the space requiring cooling, achieving environmental protection and energy saving. A defrosting component removes frost from the inner walls of the cold storage unit, preventing it from interfering with the lifting component's operation and reducing the refrigeration unit's energy consumption. While this equipment can meet basic refrigeration needs, its air inlet filtration capacity is weak. Impurities can enter the refrigeration unit with the air, accelerating component wear and potentially causing mechanical failures, affecting the equipment's lifespan and stability, and increasing maintenance costs and downtime. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly and energy-saving cold storage refrigeration equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly and energy-saving cold storage refrigeration equipment, including a cold storage wall for an environmentally friendly and energy-saving cold storage, an air inlet box for gas circulation installed on one side of the cold storage wall, and an air diffuser provided inside the air inlet box;

[0006] The air inlet box has a sliding groove inside, and a filter plate frame for support is slidably installed inside the sliding groove. Handles for assisting the movement of the filter plate frame are welded to both sides of the filter plate frame. Three limiting grooves for limiting the position are installed inside the filter plate frame, and filter plates for filtering the gas are installed inside each of the three limiting grooves.

[0007] Preferably, the bottom of the air inlet box is provided with an air inlet for the cold storage gas to enter, and the interior of the air inlet box is provided with three ventilation channels for gas circulation. Each of the three ventilation channels is equipped with a protective cover, and a fan is installed inside the protective cover.

[0008] Preferably, one of the ventilation channels has a conical guide block welded to its vertical inner wall for controlling gas flow, and the surface of the conical guide block is provided with a plurality of airflow grooves for guiding gas flow.

[0009] Preferably, a fixing frame is welded to the other side of the cold storage wall, and a refrigeration unit for refrigeration of the environmentally friendly and energy-saving cold storage is installed on the side of the fixing frame. The refrigeration part of the refrigeration unit is installed inside the air inlet box.

[0010] Preferably, the top of the air inlet box is connected to an air outlet hopper for air outlet, and two rotating shafts are rotatably installed inside the air outlet hopper.

[0011] Preferably, multiple baffles for turbulence are installed on the outer periphery of both rotating shafts, a guide plate for gas diversion is welded inside the air outlet hopper, and air outlets are provided on both sides of the air outlet hopper.

[0012] Preferably, a control switch for control is installed on the side of the air inlet box.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This environmentally friendly and energy-saving cold storage refrigeration equipment benefits from the structure of the filter plates and filter plate racks. Gas comes into contact with the filter plates, which filter the incoming gas, preventing impurities from affecting the equipment. After a period of time, pulling the handle moves the used filter plates away from the air inlet, while the unused filter plates move above the air inlet, allowing for easy removal and replacement. During replacement, the filter plates continuously filter the incoming gas, eliminating the need to stop the machine and increasing filtration continuity. Compared to traditional environmentally friendly and energy-saving cold storage refrigeration equipment with weaker filtration capabilities, this structure enhances filtration, preventing impurities from entering the refrigeration equipment with the air, reducing component wear, increasing equipment lifespan and stability, and reducing maintenance costs and downtime.

[0015] This environmentally friendly and energy-saving cold storage refrigeration equipment benefits from the structure of the baffle plate. The baffle plate drives the rotating shaft to rotate, and the rotation of the baffle plate turbulents the cold air, which can make the cold air flow in the cold storage more uniform, avoid temperature stratification, reduce local overheating or undercooling areas, and allow the cold air to come into better contact with the goods by disturbing the airflow, thereby improving refrigeration efficiency and ensuring that the goods are stored in a uniform low temperature environment, which is conducive to ensuring the quality of the goods and extending their shelf life.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5An environmentally friendly and energy-saving cold storage refrigeration equipment is shown, including a cold storage wall 1 of the environmentally friendly and energy-saving cold storage, an air inlet box 202 for gas circulation is installed on one side of the cold storage wall 1, and an air diffuser 305 is provided inside the air inlet box 202.

[0027] The air inlet box 202 has a sliding groove 3 inside, and a filter plate frame 302 for support is slidably installed inside the sliding groove 3. Handles 301 for assisting the movement of the filter plate frame 302 are welded to both sides of the filter plate frame 302. Three limiting grooves 303 for limiting are installed inside the filter plate frame 302. Filter plates 304 for filtering gas are installed inside each of the three limiting grooves 303. When gas enters the ventilation channel 206, the gas comes into contact with the filter plates 304, and the filter plates 304 filter the incoming gas to prevent impurities from affecting the equipment. After a period of time, the handle 301 is pulled, and the used filter plates 304 move away from the air inlet 306, while the unused filter plates 304 move above the air inlet 306. The used filter plates 304 can then be removed for replacement. During the replacement process, the filter plates 304 continuously filter the incoming gas without stopping the machine, increasing the continuity of filtration.

[0028] The bottom of the air inlet box 202 is provided with an air inlet 306 for the entry of cold storage gas. The interior of the air inlet box 202 is provided with three ventilation channels 206 for gas circulation. Each of the three ventilation channels 206 is equipped with a protective cover 204. A fan 205 is installed inside the protective cover 204. A conical guide block 207 for controlling gas flow is welded to the vertical inner wall of one of the ventilation channels 206. The surface of the conical guide block 207 is provided with multiple airflow grooves 208 for guiding gas flow. The filtered gas comes into contact with the surface of the conical guide block 207. The airflow grooves 208 guide the gas flow direction. The conical guide block 207 restricts the amount of gas entering. A portion of the gas enters the other two ventilation channels 206 through the air diffuser 305, increasing the contact between the gas and the refrigeration unit 201 and increasing the refrigeration efficiency.

[0029] A mounting bracket 2 is welded to the other side of the cold storage wall 1. A refrigeration unit 201 for refrigeration of the environmentally friendly and energy-saving cold storage is installed on the side of the mounting bracket 2. The refrigeration unit 201 includes core components such as a variable frequency compressor and a condenser that combines air cooling and water cooling. The condenser has a large heat dissipation when it is working and good outdoor air circulation, which is conducive to rapid heat dissipation. The variable frequency compressor generates noise when it is running, and placing it outdoors can reduce interference to the inside of the cold storage. Meanwhile, the open outdoor space facilitates equipment installation, inspection, and maintenance. The refrigeration section of the refrigeration unit 201 is installed inside the air inlet box 202. The top of the air inlet box 202 is connected to an air outlet duct 203 for air discharge. Two rotating shafts 5 are rotatably installed inside the air outlet duct 203. Multiple baffles 501 for turbulence are installed on the outer periphery of each of the two rotating shafts 5. A guide plate 503 for gas diversion is welded inside the air outlet duct 203. Air outlets 502 are provided on both sides of the air outlet duct 203. When the fan 205 is turned on, the fan 205 draws the gas in the cold storage from the air inlet 306 into the ventilation channel 206, where the gas comes into contact with the refrigeration section of the refrigeration unit 201. The gas in the ventilation duct 206 is cooled to form cold air, which is discharged through the air outlet 203 and the fan 205, completing the refrigeration of the cold storage. The cooled gas comes into contact with the baffle 501, which drives the rotating shaft 5 to rotate. The rotation of the baffle 501 turbulents the cold air, making the cold air flow in the cold storage more uniform, avoiding temperature stratification, and reducing local overheating or undercooling areas. By turbulent airflow, the cold air can better contact the goods, improving refrigeration efficiency and ensuring that the goods are stored in a uniform low-temperature environment, which is conducive to ensuring the quality of the goods and extending their shelf life. The turbulent gas is discharged through the air outlet 203 and the air outlet 502.

[0030] A control switch 4 for control is installed on the side of the air inlet box 202. The controller and display screen are generally installed on the outside of the cold storage for easy operation and observation. The control switch 4 allows operators to monitor and adjust the operating status of the refrigeration equipment. The refrigeration unit 201 is turned on by the control switch 4, and the refrigeration unit 201 performs refrigeration.

[0031] Working principle

[0032] This environmentally friendly and energy-saving cold storage refrigeration equipment operates by first turning on the refrigeration unit 201 using control switch 4. The refrigeration unit 201 then begins refrigeration. Simultaneously, the fan 205 draws gas from the cold storage into the ventilation channel 206 through the air inlet 306. The gas comes into contact with the refrigeration unit 201, cooling the gas in the ventilation channel 206 and forming cold air. This cold air is then discharged through the air outlet 203 and the fan 205, completing the cold storage refrigeration process. When gas enters the ventilation channel 206, it comes into contact with the filter plate 304, which filters the incoming gas to prevent impurities from affecting the equipment. After a period of time, pulling the handle 301 moves the used filter plate 304 away from the air inlet 306, while the unused filter plate 304 moves above the air inlet 306, allowing it to be removed for replacement. During replacement, the filter plate 304 continuously filters the incoming gas. The system filters the air without requiring downtime for replacement, increasing the continuity of filtration. The filtered gas comes into contact with the surface of the conical guide block 207, and the airflow groove 208 guides the gas flow direction. The conical guide block 207 limits the amount of gas entering. A portion of the gas enters the other two ventilation channels 206 through the diffuser 305, increasing the contact between the gas and the refrigeration section of the refrigeration unit 201, thus increasing refrigeration efficiency. The refrigerated gas comes into contact with the baffle 501, which drives the rotating shaft 5 to rotate. The rotation of the baffle 501 turbulents the cold air, making the cold air flow in the cold storage more uniform, avoiding temperature stratification, and reducing areas of localized overheating or undercooling. By turbulent airflow, the cold air can better contact the goods, improving refrigeration efficiency and ensuring that the goods are stored in a uniform low-temperature environment, which is beneficial for ensuring the quality of the goods and extending their shelf life. The turbulent gas is discharged through the exhaust duct 203 and the exhaust port 502.
