Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, and more specifically, to a refrigerated centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Refrigerated centrifuges are divided into low-speed and high-speed refrigerated centrifuges, as well as ultra-speed analytical and preparative dual-purpose refrigerated centrifuges.

[0003] The existing refrigerated centrifuge controls the rotor to rotate by driving the motor when in use. The rotating rotor drives the test product or solvent to be centrifuged to rotate. The rotating object generates centrifugal force when rotating, which accelerates the reaction and stratification of the substances inside the object and speeds up the progress of the experiment. However, in actual use, due to the centrifugal force, the water vapor inside the rotating object will evaporate quickly, and the volatilized water vapor will gather on the wall surface of the centrifugal bin and condense into water droplets. After use, the existing device will wipe off the condensed water droplets on the surface of the centrifugal bin, but the operation process is cumbersome and requires the removal of certain equipment parts. At the same time, the parts are easily damaged when the parts are removed.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a refrigerated centrifuge. Utility Model Content

A connecting rod is provided on the surface of the rotating shaft, and the wiping plate is detachably installed on the upper end of the connecting rod.

[0009] Preferably, the centrifugal bin is a cylindrical bin body, which is opened at the center of the centrifugal box.

The temperature control platform 11 is used to control the operation of the entire internal process of the centrifuge and temperature regulation.

[0024] The temperature control platform 11 is provided with a start switch, a temperature control switch and a parameter adjustment interface. Before starting, the user first sets the speed parameters and temperature parameters required for the centrifugation through the parameter adjustment interface, then places the object to be centrifuged inside the centrifuge box 1, presses the start switch, and starts the centrifuge.

[0025] The driving component is used to complete the centrifugal action, including a rotating shaft 4, which is installed at the bottom of the centrifugal chamber 2. The rotating shaft 4 is connected to a driving motor, which is arranged inside the centrifugal box 1. A rotor 5 is arranged on the rotating shaft 4, and the rotor 5 is in a block shape. A fixing frame 7 is arranged around the rotor 5, and a placement bin 6 is arranged between two adjacent fixing frames 7. The fixing frame 7 is Y-shaped, and the sides of every two fixing frames 7 can be fixedly installed on the placement bin 6 by bolts. The placement bin 6 is used to place objects to be centrifuged.

[0026] The driving motor is started to drive the shaft 4 to rotate, and the rotating shaft 4 drives the rotor 5 to rotate. Since the fixing frame 7 is Y-shaped, the placement bins 6 between the two can be clamped and fixed by the fixing frame 7 more stably, so that the rotor 5 can drive the placement bins 6 installed on the fixing frame 7 to rotate stably, and there is no need to worry about the placement bins 6 falling off due to centrifugal force and other factors.

[0027] The scraping assembly is used to automatically scrape off water droplets generated by centrifugal action on the wall of the centrifugal chamber 2 during centrifugation, including a wiping plate 9 that fits the wall of the centrifugal chamber 2, a connecting rod 8 is provided on the surface of the rotating shaft 4, and the wiping plate 9 is detachably installed on the upper end of the connecting rod 8, and a clamping block 12 is provided at the end of the connecting rod 8. A clamping groove 13 is provided at the bottom of the wiping plate 9, the clamping block 12 is a T-block, and the clamping groove 13 is a T-slot.

When the rotor 5 drives the placement bin 6 to rotate, it automatically drives the sponge strip 14 to rotate, thereby realizing the function of automatically cleaning the bin wall of the centrifugal bin 2. The operation is simple, which is convenient for the staff to perform centrifugal work, and the structure is simple and the installation cost is low.

[0029] When centrifugation is finished, the user can use the detachable structure of the connecting rod 8 and the wiping plate 9 to pull out the wiping plate 9 with the card slot 13 connected to the inside of the connecting rod 8, and replace the used wiping plate 9.
