Description
Technical field
The utility model is related to hand-rail type can test the speed centrifuge, belong to technical field of experiment equipment.
Background technology
Centrifuge is to utilize centrifugal force, the machine of separation liquid and each component in solid particle or the mixture of liquid and liquid
Tool.Centrifuge is mainly used in separating the solid particle in suspension and liquid, or by two kinds of density differences in emulsion, and mutually
Immiscible liquid separates (such as cream is isolated from milk)；It can also be used for excluding the liquid in wet solid, such as with
Washing machine dries wet clothes；The admixture of gas of the also separable different densities of special hypervelocity channel separator；It is close using difference
Degree or granularity solid particle in a liquid sinking speed difference the characteristics of, some sedimentation centrifuges can also be to solid particle by close
Degree or granularity are classified.Existing centrifuge volume is big, and quality weight is expensive, and needs power supply, for middle and primary schools,
And remote poverty-stricken area, it is difficult to or be rarely employed.
Existing centrifuge be mostly laboratory use it is expensive, and be not suitable for middle and primary schools use.
Utility model content
In view of this, the utility model provides hand-rail type and can tested the speed centrifuge, avoids being changed to as driving force using electricity

Principle of the present utility model is that hand-operated centrifuge rotates curved handle, other end connection first gear, so as to drive
First gear is rotated, and a little gear is mutually engaged with gear wheel, and first gear is mutually engaged with second gear, and the axle center of second gear is consolidated
Determine connection rotating shaft, rotating shaft is fixed by support, and concentrator bowl and flabellum are fixedly connected with rotating shaft, so as to drive concentrator bowl and flabellum
Rotate, be provided with centrifuge tube placing tube on concentrator bowl, it is possible to achieve centrifugal action, flabellum by rotational band come wind-force blow to cone
With rotating shaft on the same line, the axle center of socket and the taper bucket is in 30-150 ° of angle, and scale is provided with socket in the axle center of shape bucket
Line, bead move up and down along socket, cause bead to fly up upwards, the height to be flown up by bead, determine the rotating speed of centrifuge.
The beneficial effects of the utility model：The hand centrifuge small volume that tests the speed after correcting, light weight, cost is low,
And middle and primary schools and the area without electricity are applicable to, and the process of centrifugation can be observed.
