[0030] Example 1

[0031] like Figures 1-5 As shown, this utility model provides a technical solution:

[0032] A high-capacity, high-speed refrigerated centrifuge includes, but is not limited to, a housing 1, a centrifuge assembly 2, and a double-layer shock-absorbing structure 3; the housing 1 is provided with a support plate 4 for supporting the centrifuge assembly 2, and the double-layer shock-absorbing structure 3 is disposed between the centrifuge assembly 2 and the support plate 4; the centrifuge assembly 2 is provided with a plurality of large-capacity test tubes 5.

[0033] Based on the above structure, the centrifugal assembly 2 is supported by the support plate 4, enabling the centrifugal assembly 2 to rotate at high speed in the structure of the box 1. At the same time, a double-layer shock absorption structure 3 is set between the support plate 4 and the centrifugal assembly 2, which can enable the centrifugal assembly 2 to perform centrifugal motion more stably and with low noise.

[0034] As an example, an electronic door 11 is hinged to the top of the box 1, and a receiving cavity 12 for accommodating the rotating part of the centrifugal assembly 2 is provided at the upper end of the box 1; a power component 13 is provided between the electronic door 11 and the support plate 4.

[0035] Based on the above structure, the opening or closing of the electronic door 11 is achieved by the power component 13, so that the centrifugal assembly 2 can perform centrifugal operation in a relatively closed environment.

[0036] As an example, the power component 13 can be a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod; the power component 13 is hinged to the support plate 4, and a clearance groove 14 that cooperates with the power component 13 is provided on the top of the housing 1.

[0037] Based on the above structure, the smooth opening and closing of the electronic door 11 is achieved by the action of the power component 13 in conjunction with the clearance groove 14.

[0038] As an example, the centrifugal assembly 2 may include a centrifugal motor 21, a rotor 22 and a fan shroud 23; the rotor 22 is disposed at the output end of the centrifugal motor 21, the bottom of the fan shroud 23 is connected to the output of the centrifugal motor 21, the fan shroud 23 is a circular cavity structure with one end open, and the rotor 22 is sleeved in the fan shroud 23.

[0039] An air cover 24 is provided on the electronic door 11. The position of the air cover 24 matches that of the air cover 23. A connecting seat 25 is provided at the connection between the electronic door 11 and the air cover 24. The connecting seat 25 and the air cover 24 are connected by a sliding rod 26. The sliding rod 26 can extend and retract to a certain extent on the connecting seat 25. The sliding rod 26 has a cylindrical structure and can rotate relative to the connecting seat 25.

[0040] Based on the above structure, when the electronic door 11 is closed, the fan cover 24, under the action of gravity, closes with the fan cover 23, so that the rotor 22 and the large-capacity test tube 5 rotate in a relatively sealed space. At the same time, since the rotor is connected by the slide rod 26, the fan cover 24 can also rotate synchronously, thereby reducing the wind resistance of the rotor 22 and reducing wind noise. Moreover, the entire centrifuge chamber is sealed, and the noise can be well isolated.

[0041] As an example, the rotor 22 may include a central shaft 221 and connecting arms 222; the connecting arms 222 are evenly arranged in eight positions along the circumference of the central shaft 221, and the central angle between adjacent connecting arms 222 is 45°; a through hole that mates with the centrifugal motor 21 is provided at the center of the central shaft 221.

[0042] The wall surface of the connecting arm 222 is also provided with a hollow hole 223. A connecting block 224 is provided at the end of the connecting arm 222 away from the central axis 221. The connecting block 224 is an isosceles trapezoidal structure. A connecting boss 225 is provided on both sides of the connecting block 224. The large-capacity test tube 5 is set between adjacent connecting arms 222 through the connecting boss 225.

[0043] Based on the above structure, by setting the connecting support arm 222 as a hollow structure, the weight of the entire rotor 22 can be reduced, and the rotor 22 can support heavier test tubes. At the same time, by setting the connecting support arm 222 at even intervals, the entire motion process can be more stable during centrifugal motion.

[0044] As an example, the rotor 22 is made of cast 17-4 stainless steel. Large-capacity centrifuges need to maintain stability at high speeds, requiring the rotor 22 material to possess both lightweight and high strength characteristics. Material fatigue or improper design could lead to rotor 22 breakage; therefore, the centrifuge rotor 22 is replaced with stronger cast 17-4 stainless steel instead of the ordinary cast 304 stainless steel.

[0045] As an example, a temperature sensor 6 is also provided in the accommodating cavity 12 for monitoring the temperature of the rotating part of the centrifuge assembly 2. The temperature sensor 6 monitors the temperature of the centrifuge cavity in real time, ensuring that centrifugation is always carried out within a safe temperature range.

[0046] As an example, the double-layer damping structure 3 may include a damping mounting plate 31, a damping column 32, and a suspended damper 33; a drive bearing seat 7 is provided on the output part of the centrifugal motor 21, the damping mounting plate 31 is located on the lower side of the drive bearing seat 7, the damping column 32 is located between the drive bearing seat 7 and the damping plate; the suspended damper 33 is located between the damping mounting plate 31 and the support plate 4.

[0047] Based on the above structure, the damping mounting plate 31 and the drive bearing seat 7 are flexibly connected by the damping column 32, which initially plays a role in damping. At the same time, the damping mounting plate 31 and the support plate 4 are connected by the hoisting damper 33, which further realizes the overall damping operation. Through the cooperation of the damping column 32 and the hoisting damper 33, a higher damping effect can be achieved.

[0048] As an example, the damping plate is a triangular structure, with its geometric center collinear with the central axis of the drive bearing housing 7. Multiple damping columns 32 are evenly arranged around the bottom surface of the drive bearing housing 7. The suspended dampers 33 are respectively set at the three corners of the damping plate.

[0049] Based on the above structure, placing the drive bearing housing 7 at the geometric center of the damping plate can make the damping effect of the damping column 32 and the suspended damper 33 more balanced, and can significantly reduce vibration.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
