Description

Technical Field

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

[0002] A refrigerated high-speed centrifuge is a high-speed centrifuge with a rotation speed of 3500-50000r / min and a refrigeration function. It uses the strong centrifugal force generated by the high-speed rotating rotor to cause the substances with different sedimentation coefficients in the suspension or emulsion in the centrifuge tube to settle, thereby separating, concentrating and purifying them. Because it has a refrigeration system, the temperature of the centrifuge chamber can be accurately controlled, which can not only meet the extraction of biological reagents with strict requirements for low temperature control, but also improve the centrifugal efficiency. It is widely used in the field of life science research.

[0003] After searching, the invention patent with the announcement number CN115569744A discloses a filtering and separating high-speed refrigerated centrifuge, including a centrifuge body, a cover plate, a mounting plate, a slot, a support plate and a shock-absorbing mechanism arranged on the side of the mounting plate, wherein the cover plate is rotatably connected to the surface of the centrifuge body, the bottom of the centrifuge body is fixedly connected with the mounting plate, and the side of the cover plate is provided with a slot; the filtering and separating high-speed refrigerated centrifuge, by providing a movable plate, when the movable plate is subjected to the left and right swinging force of the centrifuge body, the "V"-shaped angle will become larger, and then the two groups of buffer blocks will be subjected to the thrust from the movable plate and move away from each other along the limit rod, because the buffer spring is fixedly connected to the buffer block, the buffer spring will be squeezed when the buffer block moves, and when the buffer spring is reciprocatingly squeezed, the force brought by the buffer block will be relieved, and under the action of the shock-absorbing spring and the telescopic rod, the swinging force can be further relieved.

[0004] However, the above patent still has the following shortcomings: although the centrifuge can be moved by the roller and supported by the support plate, the centrifuge can only be kept level when the ground is completely level, which is not convenient for adjusting the level of the centrifuge as a whole; in addition, it is not convenient to protect the outside of the centrifuge when it is not in use, and dust is easy to fall on the centrifuge. When taking and placing centrifugal materials, dust is easy to enter the centrifuge tube, affecting the purity of the centrifugal materials. For this reason, we propose a filtering and separation high-speed refrigerated centrifuge. Utility Model Content
