Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving and environmentally friendly integrated cold storage equipment, and specifically, to environmentally friendly and energy-saving integrated cold storage equipment. Background Art

[0002] Cold storage is a device for storing low-temperature goods. It is usually used to store food, medicine, chemicals and other goods that need to be stored at a specific low temperature to maintain quality and safety.

[0003] At present, cold storage equipment on the market usually installs door closers on the doors. After the assistant opens the door, the door will be automatically closed to reduce the loss of cold air. These door closers usually use a torsion spring door closer, including a door leaf plate and a door frame plate that rotate with each other through a hinge shaft. A torsion spring is sleeved on the hinge shaft, one end of the torsion spring abuts against the door leaf plate, and the other end abuts against the door frame plate. When the door is opened or closed, the door leaf plate and the door frame plate that rotate with each other through the hinge shaft, and the torsion spring on the hinge shaft can use its own elastic restoring force to push the door to close automatically.

[0004] During long-term use of the warehouse door, the torsion spring in the door closer will gradually fatigue, making the door closer insufficient in closing force, which may cause the warehouse door to fail to close automatically, resulting in cold air leakage in the cold storage. Or after replacing a new torsion spring, the door is closed too hard and too fast, which may cause damage to the door body and door frame, or even hit the staff.

[0005] Therefore, it is necessary to adjust the force of the torsion spring in the door closer. However, in the existing door closer on the warehouse door, because the torsion spring is located between the door leaf plate and the door frame leaf plate, when it is necessary to adjust it, the entire door closer needs to be removed to remove the torsion spring sleeved on the hinge shaft, which is troublesome, time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7As shown, the environmental protection and energy-saving integrated cold storage equipment proposed in this embodiment includes a cabinet 1, a refrigeration fan 9 fixedly connected to the inner wall of the cabinet 1, and the refrigeration fan 9 is fixedly connected to the inner wall of the cold storage room. The advantage is that the refrigeration fan 9 can be directly fixed on the inner wall of the cold storage room to save ground space, making the inner space of the cold storage more abundant and convenient for the storage and handling of goods. By fixing the refrigeration fan 9 on the inner wall of the cold storage room, its stability can be improved, the adverse effects that may be caused by vibration and displacement can be reduced, and the normal operation of the refrigeration system can be ensured. The refrigeration fan 9 fixed on the wall is easier to maintain and clean, and the maintenance personnel can more conveniently approach and perform necessary maintenance work. One end of the refrigeration fan 9 is connected to the drain pipe, and the other end is connected to the cabinet 1, and the connection with the cabinet 1 is sealed with a sealing ring. The use of a sealing ring can effectively seal the connection point between the drain pipe and the cabinet, prevent water or moisture from leaking, and maintain the sealing and normal operation of the system. Through a reasonable sealing design, water can be prevented from leaking from the connection between the drain pipe and the cabinet 1, preventing the wall from being damp, corroded or other adverse effects.

[0029] Most bacteria will stop growing at low temperatures, but they will not be completely killed. Therefore, in this embodiment, an ultraviolet germicidal lamp 10 is set in the cabinet 1. The cold storage room is an important place for food processing and storage. By using the ultraviolet germicidal lamp 10, the spread of infectious diseases can be reduced and the health and safety of employees and consumers can be guaranteed. The ultraviolet germicidal lamp 10 can quickly and effectively kill microorganisms such as bacteria and viruses in the air, thereby improving the hygiene level in the cold storage room. The use of the ultraviolet germicidal lamp 10 can automatically sterilize without manual operation, reducing the time and labor intensity of cleaning work and improving work efficiency.

[0030] The cabinet body 1 is provided with a cabinet body 1 and a cold storage door group 2; a heat insulation board 102 and a heat preservation material 101 are provided inside the cabinet body 1; the heat preservation material 101 is filled on both sides of the heat insulation board 102; the heat insulation board 102 inside the cabinet body 1 is a metal heat insulation board 102, and the metal heat insulation board 102 has a low thermal conductivity, which can effectively block the conduction of external heat to the inside, thereby reducing the temperature change inside the cold storage. Filling the heat preservation material 101 on both sides of the metal heat insulation board 102 can further enhance the heat insulation effect and ensure the stability of the temperature inside the cold storage. Filling the heat preservation material 101 can form a uniform heat preservation layer on both sides of the metal heat insulation board 102, while providing additional support and protection, thereby increasing the strength and stability of the cabinet structure. By using the metal insulation board 102 and filling the insulation material 101 on both sides, the formation of cold bridges can be effectively avoided, energy transfer can be reduced, and condensation can be prevented, so as to achieve the effect of energy saving and environmental protection. The filling insulation material 101 is made of glass wool material, which has good thermal insulation performance, can effectively reduce the transfer of cold inside the cold storage, reduce energy consumption, and is conducive to maintaining a stable temperature inside the cold storage. The glass wool material is very light, so it can reduce the load of the cold storage cabinet, make the structure inside the cold storage more stable, and also help to reduce the consumption of building materials. Glass wool material is an environmentally friendly insulation material 101, which is non-toxic and harmless, will not cause harm to human health, and meets the requirements of modern buildings for environmental protection and health. Filling glass wool material is relatively convenient to construct, and can effectively fill the gaps and gaps of the cabinet to ensure the airtightness and insulation effect of the entire cabinet.

[0031] The cold storage door group 2 is provided with an outer door group 3 and an inner door group 4; the inner door group 4 includes an inner door 401 and an inner door frame 402; the outer door group 3 includes an outer door 301 and an outer door frame 302; the inner door 401 is hinged to the inner door frame 402, and a door handle 8 is provided on the inner door 401, and the door handle 8 is magnetically connected to the inner door frame 402; the outer door 301 is hinged to the outer door frame 302. Since the outer door group 3 and the inner door group 4 are both composed of doors and door frames, and there is an air layer between the outer door group 3 and the inner door group 4, the temperature difference between indoor and outdoor can be effectively isolated to achieve a good insulation effect. The outer door group 3 and the inner door group 4 are both hinged. The advantage is that the hinged design can make the door leaf have greater flexibility when opening and closing. This design allows the door leaf to rotate along one or more axes, so that the door leaf can be opened at different angles to meet different usage requirements. A magnetic connection is provided between the inner door 401 and the inner door frame 402. This design can effectively prevent cold air leakage and hot air from entering, and ensure the stability of the interior of the cold storage. A door handle 8 is provided on the inner door assembly 4 for easy operation. At the same time, a magnetic connection is provided between the door handle and the inner door frame 402, so that the door handle 8 can be firmly fixed on the door and is not easy to loosen.

[0032] The interior of the inner door 401 of the cold storage and the interior of the outer door 301 are provided with an insulation board 11, a metal plate 12, and a fireproof board 13. One side of the metal plate is fixedly connected to the insulation board, and the other side of the metal plate is fixedly connected to the fireproof board. The advantage is that the metal plate 12 can increase the mechanical strength of the door leaf, and at the same time serve as a supporting structure for the internal insulation material, and the insulation board 11 can effectively isolate the heat exchange between the internal and external environments. In addition, the fireproof board 13 can also play the role of fire isolation. This structure can effectively maintain the low temperature state in the cold storage and reduce energy consumption. The metal plate 12 has high mechanical strength, can improve the wind pressure resistance of the door leaf, and increase the stability and safety of the cold storage door group. The insulation board 11, the metal plate 12 and the fireproof board 13 play a supporting structure, and at the same time, can effectively resist impact and vibration to avoid damage to the door leaf.

[0033] The insulation board 11 is provided with a fiberboard 14 made of rice husk material, which has a low thermal conductivity and good thermal insulation performance. Rice husk is a byproduct of crops. Using rice husk to make fiberboard can effectively utilize agricultural waste resources and reduce environmental pollution. Compared with traditional wood fiberboard, rice husk fiberboard has lower carbon emissions and energy consumption.

[0034] A rubber sheet 16 is also provided inside the fireproof board 13, and a fireproof coating 15 is coated on the surface of the rubber sheet 16. The rubber sheet 16 has good elasticity and shock absorption effect. Adding the rubber sheet 16 to the fireproof board 13 can enhance its shockproof performance. The rubber sheet 16 also has good thermal insulation performance and can play a role in thermal insulation. The fireproof coating 15 is coated on the surface of the rubber sheet 16 to form a protective layer, which effectively slows down the burning speed of the rubber sheet and reduces the risk of fire.

[0035] The inner door group 4 is provided with a door closer 7, and a connecting rod 701 and a bracket 702 are provided on one side of the door closer 7. One end of the connecting rod 701 is rotatably connected to the bracket 702, and the bracket 702 is fixedly connected to the inner door 401. Due to the rotational connection between the connecting rod 701 and the bracket 702, the weight of the inner door 401 can be evenly distributed to both sides of the door closer 7. At the same time, since the bracket 702 is fixedly connected to the inner door 401, the support strength is greater and the weight of the inner door can be better supported. The rotational connection between the connecting rod 701 and the bracket 702 can make the opening and closing movement of the inner door 401 more stable, reduce the shaking and fluctuation of the inner door, and increase the stability of the inner door. The rotational connection between the connecting rod 701 and the bracket 702 can reduce the friction between the inner door 401 and the door closer 7, thereby reducing the difficulty of opening and closing the inner door and increasing the smoothness of use. The connection between the connecting rod 701, the bracket 702 and the inner door 401 is fixed by screws and nuts, which is convenient for disassembly and maintenance, and improves maintenance efficiency.

[0036] The door closer 7 is mounted on the inner door frame 402 and is provided with a torsion spring structure 703 and a stop block 712 for adjusting the force of closing the door. The torsion spring structure includes a torsion spring 706 and a tension adjuster 704. The advantage of the tension adjuster 704 being provided at one end of the door closer 7 away from the connecting rod 701 is that the adjustable torsion spring structure 703 can provide more flexible force adjustment. The design of the door closer 7 and the connecting rod 701 can make the door body more stable when closing, avoiding the situation of sudden closing or opening. The connecting rod 701 is provided with a stop rod 707, and the stop rod 707 is provided with a first stop hole 705 for fixing the torsion spring 706. The tension adjuster 704 is provided with a second stop hole 709 for fixing the torsion spring, and the other end of the torsion spring 706 is fixedly connected to the second stop hole 709. One end of the torsion spring 706 is fixedly connected to the first stop hole 705 on the stop rod 707, and the other end is fixedly connected to the second stop hole 709 on the tension adjuster 704. By adjusting the tension adjuster 704, the degree of stretching of the torsion spring 706 can be changed, thereby adjusting the force applied by the door closer 7 to the door body. By turning the knob hand wheel 708 on the tension adjuster 704, the tightness of the torsion spring 706 can be adjusted manually, or by using a screwdriver to leverage and cooperate with the knob hand wheel 708 to adjust the tightness of the torsion spring 706.

[0037] One end of the tension adjuster 704 close to the limiting rod 707 is provided with a second threaded hole 713 coaxially arranged with the limiting rod 707, one end of the torsion spring 706 is fixedly connected with the first limiting hole 705, the other end of the torsion spring 706 is fixedly connected with the second limiting hole 709, and the tension adjuster 704 is threadedly connected with the second threaded hole 713. The door closer 7 is provided with a limiting block 712, and the limiting block 712 is provided with a second threaded hole 713 threadedly connected with the tension adjuster 704, and the knob hand wheel 708 of the tension adjuster 704 is easy to operate when adjusting. The rotation direction design of the torsion spring 706 in this embodiment is that when the knob handwheel 708 is rotated counterclockwise, the number of turns of the torsion spring 706 increases, and the distance between the first limit hole 705 and the second limit hole 709 is shortened, so that the torsion spring 706 is tightened; when the knob handwheel 708 is rotated clockwise, the number of turns of the torsion spring 706 decreases, and the distance between the first limit hole 705 and the second limit hole 709 is lengthened, so that the torsion spring 706 is loosened. In addition, this embodiment also provides a limit screw 711 for fixing the limit tension adjuster 704 and a first threaded hole 710 for fixing the limit screw 711 on the limit block 712. When the tension adjuster 704 is rotated to an appropriate force, the limit screw 711 is rotated again to make the limit screw 711 abut against the thread of the tension adjuster 704, cooperate with the self-locking force of the tension adjuster 704, and avoid the torsion spring 706 from rebounding too much, causing the tension adjuster 704 to rotate, thereby changing the closing force of the warehouse door.

[0038] The inner door is provided with a first observation window 5; the first observation window 5 includes an insulating glass 501 and a sealing strip 502; the first observation window 5 is embedded in the inner door 401; the edge of the insulating glass 501 is wrapped by the sealing strip 502. The insulating glass 501 has a low thermal conductivity and can effectively reduce heat conduction. By embedding the insulating glass 501 in the inner door 401 and wrapping the edge with a sealing strip 502, cold air leakage and hot air entry can be prevented, thereby improving the thermal insulation performance of the cold storage. By wrapping the edge of the insulating glass 501 with a sealing strip 502, air and moisture penetration can be effectively prevented, ensuring the sealing performance of the cold storage and avoiding any form of leakage. The first observation window 5 can be set to clearly observe the situation inside the cold storage, which is convenient for operation and monitoring. At the edge of the first observation window, a sealing strip 502 is used to ensure the sealing performance of the first observation window 5 and the inner door 401. The sealing strip 502 is usually made of rubber or other elastic materials, which can fit the window frame and the inner door tightly, prevent cold air leakage and moisture from entering, and maintain the normal temperature and humidity of the cold storage. The sealing strip 502 is made of EPDM (ethylene propylene rubber) material. The rubber sealing strip performs well in low temperature environments and can maintain good elasticity and sealing performance. In particular, the EPDM (ethylene propylene rubber) material has excellent cold resistance and can remain soft in extremely cold conditions.

[0039] A door-blocking block 6 is provided between the inner door group 4 and the outer door group 3. The door-blocking block 6 can limit the opening range of the inner door group 4 and the outer door group 3 to prevent them from colliding with each other and being damaged, thereby increasing the service life of the cold storage equipment. The door-blocking block 6 can ensure the safe opening and closing of the door, thereby improving operational safety and preventing accidents. By providing the door-blocking block 6 between the inner door group 4 and the outer door group 3, it can ensure that the inner door group 4 and the outer door group 3 are closed in the correct position, avoiding potential safety hazards caused by the door not being completely closed or not being closed correctly, such as temperature fluctuations, damage to items, etc. In general, providing a limit rod can improve the durability, thermal insulation effect and safety of the door, which is very beneficial to the normal operation of the cold storage.

[0040] The outer door group 3 is provided with a second observation window 303, which is embedded in the outer door 301. This design has the following characteristics: the second observation window 303 is provided so that the situation inside the cold storage can be clearly observed before the outer door 301 is opened, which is convenient for operation and monitoring. Since the second observation window 303 is embedded in the outer door 301, when observation is needed, it can be observed only through the second observation window 303 without opening the entire outer door 301, thereby effectively reducing the loss of cold air and maintaining the temperature inside the cold storage stable.

[0041] The advantage of the outer door group 3 using a double-opening sliding door design and the inner door group 4 using a fully embedded door design is that the thermal insulation effect is better. The inner door group 4 uses a fully embedded door design, which can make the inner door 401 completely flush with the cabinet body 1, avoiding air leakage and water leakage between the door gap and the wall gap, thereby improving the thermal insulation effect. The outer door 301 adopts a double-opening sliding door design, which can reduce temperature loss when the outer door 301 is opened and enhance the thermal insulation effect.

[0042] At the same time, it also has the following beneficial effects:

[0043] 1. Safer and more reliable: The outer door 301 with a double-opening sliding door design can make it more convenient and quick to enter and exit the cold storage, which improves work efficiency. At the same time, it can also effectively reduce the wear of the outer door 301 caused by frequent opening and closing of the outer door 301, thereby increasing the service life of the outer door 301.

[0044] 2. Higher space utilization: In some environments with limited space, the design of two doors inside and outside can make full use of the space, especially the design of double sliding doors saves more space and does not occupy any space when the door is opened. More beautiful and generous: The inner door adopts a fully embedded door design, which can make the door fit the wall completely to achieve an overall unified effect, and the outer door adopts a double sliding door design, which is more elegant and beautiful.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
