Description

Technical Field

[0001] The utility model relates to the technical field of cold storage defrosting, in particular to a cold storage refrigeration system. Background Art

[0002] The cold storage refrigeration system is a key component of the cold storage. During the use of the cold storage, the refrigeration pipes of the cold storage refrigeration system often frost. The frost on the pipes will greatly affect the working efficiency of the cold storage refrigeration system. Due to the frost on the surface of the evaporator in the cold storage, the refrigeration evaporator (pipeline) is hindered from conducting and dissipating cold, which ultimately affects the refrigeration effect. When the thickness of the frost layer (ice layer) on the surface of the evaporator reaches a certain level, the refrigeration efficiency even drops below 30%, resulting in a large waste of electric energy and shortening the service life of the refrigeration system. Therefore, the pipes on the cold storage refrigeration system must be defrosted at intervals. At present, there are many methods for defrosting the cold storage refrigeration system, such as hot air defrosting, water spray defrosting, and electrical defrosting.

[0003] Existing hot gas defrosting often uses hot fluorinated defrosting to heat the pipes in the cold storage refrigeration system. This defrosting method has fast heating and little impact on the temperature of the cold storage. It can quickly melt and fall off the ice layer on the outer wall of the heat exchange tube to achieve the purpose of defrosting. However, the ice layer that falls off during the defrosting process will fall on the objects in the cold storage or on the ground, which is inconvenient to clean. If the removed objects are moved out of the cold storage in advance and then cleaned, production will be affected and storage will be inconvenient. Utility Model Content

[0004] In order to solve the problem in the background technology that the ice layer that falls off during the defrosting process will fall on the objects in the cold storage or the ground, making it inconvenient to clean up, and if the removed objects are moved out of the cold storage in advance and then cleaned up, production will be affected and storage will be inconvenient, the utility model proposes a cold storage refrigeration system.

[0024] A moving mechanism 6 is provided on the fixed plate 1, and the end of the plastic sheet 4 is provided on the moving mechanism 6. The moving mechanism 6 is used for driving the plastic sheet 4 to move left and right. Specifically, the moving mechanism 6 includes a first tensioning wheel 7 fixedly provided at both ends of the rotating shaft 2, and a belt 8 is connected to the first tensioning wheel 7 for transmission; fixed blocks 9 are fixedly provided at the left and right ends of the opposite sides of the two fixed plates 1, and a guide rod 10 is fixedly provided between the two fixed blocks 9 in the same left and right directions, and a guide slider 11 is slidably provided on the guide rod 10, and the left end of the plastic sheet 4 is fixedly provided on the guide slider 11, and two second tensioning wheels 12 are rotatably provided on the side of the guide slider 11 close to the fixed plate 1, and the left end of the belt 8 successively passes around the first tensioning wheel 7 on the left and the second tensioning wheel 12 on the left and is fixed on the fixed block 9 on the left, and the right end of the belt 8 successively passes around the first tensioning wheel 7 on the right and the second tensioning wheel 12 on the right and is fixed on the fixed block 9 on the right.

[0025] A driving mechanism 20 for driving the rotating shaft 2 to rotate is provided on the rotating shaft 2 located on the left, and the driving mechanism includes an axle seat 13 fixed on the inner wall of the left side of the cold storage, a chain shaft is rotatably provided on the axle seat 13, one end of the chain shaft passes through the axle seat 13 and is fixed with a turning handle 14, and a first sprocket 15 is fixed on the chain shaft; a second sprocket 16 is fixedly provided in the middle of the rotating shaft 2, and a chain 17 is meshed together with the first sprocket 15 and the second sprocket 16.
