Description

Horizontal rotor of high-speed centrifuge

Technical Field

The utility model belongs to centrifuge, concretely relates to high rotational speed centrifuge horizontal rotor.

Background

The centrifugal machine is used for separating matter, belongs to basic laboratory equipment and is used widely in life science, medicine, chemistry, environment protection and other fields. The rotor of a centrifuge is an important component of a centrifuge, which separates solid particles from a liquid in a suspension by centrifugal force generated by rotation of a rotor.

Conventional centrifuge rotor heads are classified into an angle rotor head and a horizontal rotor head. The centrifuging tube central line of angle bull becomes fixed angle with the rotation axis, and the angle is big more, and the separation effect is better, and angle bull focus is low, and the resistance is little, operates steadily, should high-speed separation, but when the granule subsides, the granule can be earlier collided to the centrifuging tube along centrifugal force direction, then along the pipe wall cunning to the socle, the particle deposit can appear in one side of test tube and the wall effect that produces, influences the separation effect.

The test tube is close perpendicular with the pivot angle when the horizontal rotary head separates, and the granule directly sinks to the test tube bottom, is favorable to the layering of granule and solution to take out, but the horizontal rotary head focus is high, and the resistance is big, should not separate at a high speed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a horizontal rotor of high rotational speed centrifuge that air resistance is little, and separation effect is good.

Realize the utility model discloses the technical scheme of purpose is:

the utility model provides a horizontal rotor of high rotational speed centrifuge, include by the rotatory drive arrangement of centrifuge motor drive, fix the fan housing on drive arrangement and cover the fan housing lid on the fan housing, the last horizontal turn that is located the fan housing that is fixed with of drive arrangement, horizontal turn is overhead to have a plurality of hanging cups that are used for inserting the test tube through hanging round pin movable sleeve along the circumference.

The horizontal rotary head is provided with a plurality of hanging arms with fork-shaped end parts along the circumference, and the hanging pins are arranged between the end parts of the adjacent hanging arms.

Has the advantages that:

the utility model provides a fan housing and fan housing lid have formed a closed and regular solid of revolution, and when drive arrangement was rotatory by centrifuge's motor drive, horizontal turning head and fan housing lid rotated in step. Because the wind cover and the wind cover form a closed and regular revolving body, the air resistance borne by the revolving body is greatly reduced, and the rotating speed of the revolving body can be greatly improved under the same driving power. The settling time t = K/S of the particles in the solution, wherein S is a settling coefficient of the particles and is a constant, K is a rotary head K value, the rotary head K value is smaller when the rotating speed is higher, and the rotating speed is increased to obtain faster settling time and better separation effect.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Fig. 2 is a cross-sectional view along AA of fig. 1.

In the figure:

1. a fan housing; 2. a wind cover cap; 3. a drive device; 4. hanging a pin; 5. horizontally turning the head; 6 hanging the cup; 7. a test tube; 8. the end of the hanging arm.

Detailed Description

See fig. 1, fig. 2, the utility model provides a horizontal rotor of high rotational speed centrifuge, including fan housing 1 and fan housing lid 2, fan housing lid 2 covers on fan housing 1, fan housing 1 is fixed on drive arrangement 3, drive arrangement 3 can be rotatory by centrifuge motor drive, be fixed with the horizontal turn 5 that is located fan housing 1 on drive arrangement 3 simultaneously, horizontal turn 5 is equipped with a plurality of arms of hanging along the circumference, the tip 8 of hanging the arm is the fork form, be equipped with between the tip 8 of adjacent arm of hanging and hang round pin 4, hang 6 movable sleeve of cup on hanging round pin 4, hang cup 6 and can follow the axis rotation of hanging round pin 4, test tube 7 can insert in hanging cup 6.

When the driving device 3 is driven to rotate by the motor of the centrifuge, the horizontal rotor 5, the fan cover 1 and the fan cover 2 rotate synchronously. Under the action of centrifugal force, the hanging cup 6 is outwards overturned along the axis of the hanging pin 4, the angle between the test tube 7 and the axis of the driving device 3 is approximately vertical, and particles directly settle to the bottom of the test tube 7 to form obvious layering of the particles and the solution. Because the wind cover 1 and the wind cover 2 form a closed and regular revolving body, the air resistance suffered by the revolving body is greatly reduced, and the rotating speed of the revolving body can be greatly improved under the same driving power. The settling time t = K/S of the particles in the solution, wherein S is a settling coefficient of the particles and is a constant, K is a rotary head K value, the higher the rotating speed is, the smaller the rotary head K value is, and the faster settling time can be obtained by increasing the rotating speed.

The present invention is not limited to the above preferred embodiments, and any other various products can be obtained by anyone under the teaching of the present invention, but any changes in the shape or structure are made, and all the technical solutions identical or similar to the present technology fall within the protection scope of the present invention.
