Description

Centrifuge rotor

Technical Field

The utility model belongs to the technical field of the experimental articles for use, concretely relates to centrifuge rotor.

Background

Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used for separating solid particles from liquid in suspension, or separating two liquids which have different densities and are insoluble with each other in emulsion (for example, cream is separated from milk); it can also be used to remove liquids from wet solids, such as by spin drying clothes in a washing machine; the special overspeed tubular separator can also separate gas mixtures with different densities; some settling centrifuges can also grade solid particles according to density or granularity by utilizing the characteristic that solid particles with different densities or granularities have different settling speeds in liquid.

The centrifuge includes a body and a rotor. When the centrifugal separation device is used, a sample to be separated is injected into the centrifugal tube, the centrifugal tube is inserted into the rotor, and the sample is separated through the high-speed rotation of the rotor. The types of rotors are angular, horizontal and vertical. Due to the fixed design of the size, the general angle rotor can only place test tubes with fixed sizes, and when centrifugal operation is required to be carried out on test tubes with various specifications, the requirement cannot be met. Moreover, no centrifuge specifically designed for glass tubes exists in the prior art. Only under the condition that certain glass tubes are enough in hardness and low in centrifugal rotating speed, centrifugal operation can be directly carried out on the glass tubes, however, in the specific condition, for the safety of the test, a plastic tube is sleeved on the outer surfaces of the glass tubes generally, and fillers are inserted into the glass tubes, so that the test can be carried out, and the operation is troublesome.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a centrifuge rotor can be directly used for the centrifugal operation of glass pipe, simple structure and facilitate the use through add pipe box and elastic material on the rotor.

A centrifuge rotor comprises a rotating shaft and a rotating disc. The turntable is of a bowl-shaped structure with a large upper part and a small lower part; the rotating shaft is arranged on the middle shaft of the rotating disc; a plurality of hollow pipe sleeves are uniformly arranged on the side surface of the rotary table; the pipe sleeve comprises an upper shell and a lower shell, and the upper shell is fixedly connected with the lower shell; a rubber layer is arranged in the upper shell and comprises at least two rubber pads; when the centrifugal tube is not inserted, the rubber pads are connected left and right to form a hollow cylinder, and the diameter of the hollow cylinder is smaller than the inner diameter of the upper shell; after the rubber pads are inserted into the centrifuge tube, the rubber pads are separated from each other; an elastic structure is arranged between the rubber layer and the upper shell; the lower shell is filled with a spongy cushion.

Further, the bottom of the pipe sleeve is of a conical structure.

Further, the elastic structure is a spring.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a through add pipe box and elastic material on the rotor, can directly be used for the centrifugal operation of glass pipe, can be applicable to the centrifuging tube of various size types, simple structure, facilitate the use, application scope are wide.
