Description

Centrifuge rotor for glass tube

Technical Field

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

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 for glass tube through add pipe box and elastic material on the rotor, can directly be used for the centrifugal operation of glass tube, simple structure and facilitate the use.

A centrifuge rotor for glass tube comprises a rotating shaft and a rotating disk. 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, the rubber layer is of a hollow cylinder structure, and the outer wall of the rubber layer is tightly attached to the inner wall of the upper shell; the inner wall of the rubber layer is provided with a plurality of suckers; the lower shell is filled with a spongy cushion.

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

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.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to the accompanying drawings 1 and 2 of the specification, the present invention relates to a glass tube centrifuge rotor, which includes a rotating shaft 30 and a rotating disk 10. The turntable 10 is of a bowl-shaped structure with a large upper part and a small lower part; the rotating shaft 30 is arranged on the middle shaft of the rotating disc 10; a plurality of hollow pipe sleeves 20 are uniformly arranged on the side surface of the rotary table 10; the pipe sleeve 20 comprises an upper shell 21 and a lower shell 22, and the upper shell 21 is fixedly connected with the lower shell 22; a rubber layer 24 is arranged in the upper shell 21, the rubber layer 24 is of a hollow cylinder structure, and the outer wall of the rubber layer 24 is tightly attached to the inner wall of the upper shell 21; a plurality of suckers 25 are arranged on the inner wall of the rubber layer 24; the lower case 22 is filled with a sponge pad 23.

Preferably, but not limited to, the bottom of the pipe sleeve 20 has a tapered structure.

The utility model discloses a use method does: the glass tube is mounted on a centrifuge using a centrifuge rotor, and the glass tube to be tested is directly inserted into the tube housing 20, and the sponge pad 23 is automatically pressed down to a proper position according to the length of the glass tube. The rubber layer 24 is deformable rubber, and the rubber layer 24 is elastically deformed after the glass tube is inserted, so that the inner wall of the rubber layer 24 can be automatically squeezed open to the periphery according to the diameter of the glass tube. The sucking disc 25 on the inner wall of the rubber layer 24 can adsorb the glass tube, so that the glass tube is fixed, the glass tube is prevented from being upwards popped out, and meanwhile, the sponge cushion 23 and the rubber layer 24 are designed to prevent the glass tube from being cracked.

The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
