Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a cold storage with a buffer chamber. Background Art

[0002] Cold storage refers to the use of artificial means to create an environment with a different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage device for food, liquids, chemicals, medicines, vaccines, scientific experiments, etc. Cold storage is a type of refrigeration equipment. Generally, it uses a refrigeration mechanism to cool and absorb the heat in the storage to achieve the purpose of cooling.

[0003] During the use of the cold storage, the cold storage door needs to be opened frequently to operate the goods in and out of the storage, which leads to long operation time in the storage, large flow of cold air, serious loss of cold air in the storage, increased energy consumption, and increased operating costs of the cold storage. At the same time, frequent opening and closing of the cold storage will form convection between hot air outside the storage and cold air inside the storage, causing hot air containing moisture outside the storage to enter the storage, and the moisture entering the storage will freeze on the refrigeration equipment, reducing the refrigeration effect of the refrigeration equipment. Utility Model Content

[0034] Reference Figure 1-4 , a cold storage with a buffer compartment, is used in cold storage to avoid the consumption of cold air when goods enter and leave the warehouse, thereby reducing energy consumption.

[0035] The cold storage with a buffer room comprises a cold storage body 1, a buffer room 3, two first sealed doors 4, two second sealed doors 5 and an air curtain machine 8;

[0036] An insulation layer is provided in the walls of the cold storage body 1 and the buffer room 3. The buffer room 3 is arranged on one side of the cold storage body 1, and the rear end extends into the cold storage body 1. One first sealed door 4 is arranged on the rear side of the buffer room 3 to connect or separate the buffer room 3 and the cold storage body 1, and the other first sealed door 4 is arranged on the front side of the buffer room 3 to connect or separate the buffer room 3 and the external space. When the goods are in and out of the warehouse, the two first sealed doors 4 can be opened alternately to circulate the goods through the buffer room 3, thereby avoiding the internal space of the cold storage body 1 from being directly connected to the external space, thereby effectively avoiding the leakage of cold air inside the cold storage body 1 and reducing energy consumption.

[0037] Each first sealed door 4 includes two door panels, and two shaped grooves are provided on the sides where the two door panels are close to each other. The first sealing strip 12 and the second sealing strip 13 are fixedly connected in the two shaped grooves respectively. The second sealing strip 13 is located on the outside, and the sides where the two second sealing strips 13 are close to each other are provided with matching serrated grooves. A rotating member 11 is provided between the door panel and the buffer room 3. The rotating member 11 is a hinge. The two door panels can be rotated by the hinge to open or close the first sealed door 4. When the first sealed door 4 is closed, the matching serrated grooves on the two second sealing strips 13 are embedded in each other, so that the two door panels are sealed by the first sealing strip 12 and the second sealing strip 13 to prevent cold air leakage.

[0038] A second sealed door 5 is arranged on a door panel of each first sealed door 4. The second sealed door 5 is connected to the first sealed door 4 through a rotating member 11. The rotating member 11 is a hinge. The second sealed door 5 can be opened or closed by the hinge. When goods of smaller volume or smaller quantity are brought in and out of the warehouse, it is only necessary to open the second sealed door 5 to bring the goods in and out of the warehouse. Since the second sealed door 5 is smaller, the channel connecting the inside and outside of the cold storage body 1 becomes smaller, thereby reducing the leakage of cold air and improving the energy-saving effect.

[0039] The air curtain machine 8 is arranged on the top inner wall inside the buffer room 3 and is located between the two first sealing doors 4. A refrigeration device 2 is arranged on the top of the buffer room 3. The refrigeration device 2 is an air compressor. An evaporator is arranged at the air inlet of the air curtain machine 8. The refrigeration device 2 is connected to the evaporator through a pipeline. The refrigeration device 2 cools the evaporator, so that the air curtain machine 8 blows out cold air. The air curtain machine 8 blows out cold air downward. On the one hand, it can avoid the convection of hot and cold air, thereby avoiding the external hot air from entering the cold storage body 1, preventing the hot air from carrying moisture into the cold storage body 1, and reducing the refrigeration effect of the cold storage body 1. On the other hand, the air curtain machine 8 blows cold air into the buffer room 3. When the goods are out of the warehouse, the goods can be placed inside the buffer room 3 to reduce the temperature difference with the outside world, avoid the goods from being heated, and condense water droplets on the outside. When the goods are put into the warehouse, the goods are cooled to avoid the goods directly entering the cold storage body 1, causing the internal temperature to rise and affecting other stored goods.

[0040] In order to facilitate the handling of goods, a plurality of fixed seats 9 arranged at intervals are provided in the buffer room 3, and a rotating roller 6 is provided on the fixed seat 9. A conveyor belt 7 is provided on the outside of each rotating roller 6. A driving motor is provided in the buffer room 3, and the rotating roller 6 is connected to the output shaft of the driving motor. The driving motor can drive the rotating roller 6 to rotate, thereby driving the conveyor belt 7 to move. Since the two ends of the conveyor belt 7 are respectively located on one side of the two first sealing doors 4, the goods can be directly placed on the conveyor belt 7 when entering and leaving the warehouse, and then the goods can be transported to the other end of the buffer room 3 through the conveyor belt 7, which is convenient for the handling of the goods.

[0041] The buffer room 3 and the first sealed door 4 are both provided with door frames, the first sealed door 4 is arranged in the door frame of the buffer room 3, and the second sealed door 5 is arranged in the door frame of the first sealed door 4. In order to improve the sealing performance of the first sealed door 4 and the second sealed door 5, a sealing assembly 10 is arranged in the door frame, and the sealing assembly 10 includes a sealing ring 1001, a first sealing ring 1002, and a second sealing ring 1003. The sealing ring 1001 is fixed to the inner wall of the door frame, and the first sealed door 4 and the second sealed door 5 are both provided with a first sealing ring 1002 and a second sealing ring 1003 on the outside. The inner wall of the sealing ring 1001 is step-shaped, and the first sealed door 4 and the second sealed door 5 are both Two mounting grooves are provided, and the first sealing ring 1002 and the second sealing ring 1003 are fixed in the two mounting grooves respectively. Since the first sealing ring 1002 is located on the outside and its thickness is greater than that of the second sealing ring 1003, when the sealing door is closed, the first sealing ring 1002 and the second sealing ring 1003 will fit with the stepped inner wall of the sealing ring 1001, thereby sealing the door frame and the sealing door to avoid leakage of cold air. At the same time, since the cold storage with a buffer chamber adopts two first sealing doors 4 to isolate the cold storage body 1 from the external space, the sealing performance of the cold storage body 1 can be further improved, the leakage of cold air can be avoided, and the refrigeration energy-saving effect of the cold storage can be improved.

[0043] When a large number of goods are put into the warehouse, the air curtain machine 8 is turned on, and the air curtain machine 8 blows air downward, thereby isolating the air at both ends of the buffer room 3, and then the first sealed door 4 on the outside is opened to open the buffer room 3, and then the goods are placed on the conveyor belt 7, and then the first sealed door 4 on the outside is closed, so that the goods are moved to the bottom of the air curtain machine 8 through the conveyor belt 7, and the refrigeration equipment 2 is turned on to cool the evaporator, so that the air curtain machine 8 blows out cold air, and the air curtain machine 8 blows out cold air downward to cool the goods, so as to prevent the goods from directly entering the cold storage body 1, causing the internal temperature to rise and affecting other stored goods, and finally the first sealed door 4 on the inside is opened, and the goods are moved to the side of the first sealed door 4 on the inside through the conveyor belt 7, so as to facilitate the transportation of the goods to the inside of the cold storage body 1 for storage;

[0044] When a large number of goods are unloaded from the warehouse, the air curtain machine 8 is turned on, and the air curtain machine 8 blows air downward, thereby isolating the air at both ends of the buffer room 3, and then the first sealed door 4 on the inside is opened, so that the buffer room 3 is connected with the cold storage body 1, so that the goods can be placed on the conveyor belt 7, and then the first sealed door 4 on the inside is closed, so that the goods are placed inside the buffer room 3, reducing the temperature difference with the outside, and preventing the goods from being heated and condensing water droplets on the outside, and finally opening the first sealed door 4 on the outside, and the goods are moved to the side of the first sealed door 4 on the outside through the conveyor belt 7, so that the goods can be transported to the outside of the cold storage body 1;

[0045] When a small amount of goods is transported in and out of the warehouse, the air curtain machine 8 is turned on and blows air downward, thereby isolating the air at both ends of the buffer room 3. Then, the two second sealed doors 5 are opened alternately to facilitate the staff to enter and exit the cold storage body 1 through the two second sealed doors 5, thereby facilitating the transport of goods in and out of the warehouse.
