DETAILED DESCRIPTION

[0021] The technical scheme of the patent will be further described in detail in combination with specific embodiments.

[0022] Please refer to Figures 1-3 A centrifuge refrigeration device, comprising a centrifuge body 1 and a centrifugal chamber 2 arranged in the centrifuge body 1, further comprising:

[0023] A refrigeration assembly, the refrigeration assembly comprising a spiral copper pipe evaporator 5 sleeved outside the centrifugal chamber 2, and a cooling cavity 4 is formed on one side in the centrifuge body 1, two connecting pipes 7 are installed in the cooling cavity 4, and the two connecting pipes 7 are slidably connected with movable pipes 6 connected with both ends of the copper pipe evaporator 5;

[0024] An inner cavity 3 is formed in the centrifuge body 1, a motor 12 is installed in the inner cavity 3, and a centrifugal shaft 13 penetrating into the centrifugal chamber 2 is installed on the output shaft of the motor 12; two symmetrical limiting shafts 17 are installed in the inner cavity 3, a supporting plate 14 is slidably arranged on the limiting shaft 17, and connecting frames 11 connected with the copper pipe evaporator 5 are installed on both sides of the supporting plate 14;

[0025] A transmission assembly is arranged between the centrifugal shaft 13 and the limiting shaft 17 for transmission;

[0026] A pushing assembly is arranged between the transmission assembly and the supporting plate 14 for moving the copper pipe evaporator 5.

[0027] In use, the centrifugal shaft 13 is driven to rotate by the motor 12, so as to centrifugally separate the materials in the centrifugal chamber 2, and in the process of rotation of the centrifugal shaft 13, the transmission assembly drives the pushing assembly, the pushing assembly drags the supporting plate 14 to move up and down, so that the connecting frame 11 can drive the copper pipe evaporator 5 to move up and down, so that the copper pipe evaporator 5 can be in full contact with the centrifugal chamber 2 to realize full heat exchange and improve the heat exchange efficiency, and at the same time, the water droplets on the copper pipe evaporator 5 can be shaken off to avoid affecting the refrigeration effect of the water droplets.

[0028] In one case of the embodiment, the refrigeration assembly further comprises a compressor 8, a condenser 9 and an expansion valve 10, which are connected by pipes, wherein the compressor 8 is connected with one of the connecting pipes 7, and the expansion valve 10 is connected with the other connecting pipe 7.

[0029] When starting to use, the liquid refrigerant in the copper tube evaporator 5 is evaporated into gaseous refrigerant, so as to perform refrigeration heat exchange on the centrifugal chamber 2. Then the gaseous refrigerant flows through the compressor 8 to pressurize the gaseous refrigerant, and then flows into the condenser 9 to perform heat dissipation cooling. Then the gaseous refrigerant becomes low-pressure liquid refrigerant under the action of the expansion valve 10 and enters the copper tube evaporator 5 again to perform heat exchange. The copper tube evaporator 5, the condenser 9, the compressor 8 and the expansion valve 10 are main structures of the refrigeration system, and the refrigeration principle is the prior art, which will not be described in detail here.

[0030] In one case of the embodiment, the transmission assembly comprises a first gear 16 mounted on the centrifugal shaft 13, and a second gear 18 rotatably arranged on the limiting shaft 17 and engaged with the first gear 16. The radius of the second gear 18 is greater than that of the first gear 16.

[0031] In the process of rotating the centrifugal shaft 13, the first gear 16 is driven to rotate, and the rotation of the first gear 16 drives the second gear 18 engaged therewith to rotate. The radius of the first gear 16 is much smaller than that of the second gear 18, so that the second gear 18 is in a low-speed operation state, and the up-down movement frequency of the copper tube evaporator 5 is slow under the action of the pushing assembly, so as to avoid the structure damage caused by too fast up-down movement.

[0032] In one case of the embodiment, the pushing assembly comprises a rotating ring 20 mounted on the second gear 18, and a plurality of arc-shaped grooves 21 are arranged on the rotating ring 20 in a ring-shaped and spaced manner. Two U-shaped columns 19 are mounted on the bottom of the supporting plate 14 on both sides. The spring 15 is arranged between the bottom of the supporting plate 14 and the inner cavity 3.

[0033] In the process of rotating the second gear 18, the rotating ring 20 is driven to rotate, and the U-shaped columns 19 at the bottom of the supporting plate 14 also contact the rotating ring 20 under the action of the spring 15. With the rotation of the U-shaped columns 19, the U-shaped columns 19 will intermittently enter the arc-shaped grooves 21 to move up and down, so that the supporting plate 14 slides up and down along the limiting shaft 17, drives the copper tube evaporator 5 to move up and down through the connecting frame 11, and the movable pipe 6 connected with the copper tube evaporator 5 also slides up and down in the connecting pipe 7, so that the copper tube evaporator 5 can fully contact the centrifugal chamber 2 to achieve full heat exchange, improve the heat exchange efficiency, and also can shake off the water droplets on the copper tube evaporator 5 to avoid the influence of the water droplets on the refrigeration effect.
