Description
Technical field
The utility model relates to a kind of centrifuge part, especially relates to a kind of centrifuge rotor.
Background technology
Centrifuge utilizes centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Centrifuge is mainly used in the solid particle in suspension to separate with liquid, or by two kinds of density differences in emulsion, liquid immiscible again separately.There are the following problems for existing centrifuge: (1) rotor and main shaft pass through cone match, by a locknut axial compression.Locknut normally dextrorotation, in boosting velocity procedure, screw thread is more and more tighter, but in down speeding procedure, due to the inertia of rotor, have the trend that left-hand thread direction is run, do not press tightly once locknut revolves, rotor and nut can come off from main shaft, damage machine; (2) when will make centrifugal, equipment keeps adjustment of balance running, the weight in centrifuge rotor all directions must be made to reach balance, when making centrifugal, equipment keeps adjustment of balance running, loaded down with trivial details mixed liquor to be carried out before centrifugation and divide weighing work equally, namely first will treat that centrifugal total fluid is weighed, after be divided into two parts and be placed on balance both sides, heavier one side liquid is got out and pours comparatively light one side into, regulate continuously, until two parts of liquid are equal, put into symmetrical Centrifuge Cup again, centrifuge both sides are balanced.Just unbalance phenomenon can not occur when centrifuge rotates like this, but each preparation is more loaded down with trivial details, wastes time and energy.
Summary of the invention
For solving the problem, the utility model discloses a kind of centrifuge rotor.
In order to reach above object, the utility model provides following technical scheme:
A kind of centrifuge rotor, comprise main shaft, rotor and Centrifuge Cup, described rotor is arranged on main shaft, described Centrifuge Cup is arranged on rotor, described rotor is provided with connecting hole, mold insert is inlaid with in described connecting hole, described main shaft is provided with the keyway matched with mold insert, described main shaft top is provided with locknut, also comprise packed-piston and soft capsule, described packed-piston is placed in Centrifuge Cup, and soft capsule is arranged on below packed-piston, soft capsule in adjacent centrifugal cup is communicated with by tube connector, and described soft capsule is built with liquid.
As preferably, also comprise kuppe, water conservancy diversion cover cap, rotor connecting member, described kuppe is fixed on rotor connecting member, and described rotor connecting member is fixed on rotor, and described water conservancy diversion cover cap lid is located at kuppe top.
As preferably, described spindle nose is provided with the conical surface section matched with rotor.
As preferably, described kuppe covers and is provided with fastener, and described kuppe is provided with the draw-in groove corresponding with described fastener.
As preferably, described main shaft is provided with axle and embraces, and described kuppe is provided with a loop connecting platform near main shaft place, described loop connecting platform abuts described axle and embraces, described rotor connecting member is set in outside described main shaft, and its top connects described rotor, and bottom connects described loop connecting platform.
The beneficial effect that the utility model obtains is: on rotor, be inlaid with mold insert, and main shaft is provided with corresponding keyway, and ensureing can not relative motion between rotor and main shaft.In brake process, even if when locknut loosens, rotor also can not come off from main shaft, and security performance is high.Interconnect by arranging and the soft capsule of liquid is housed, centrifuge rotor autobalance can be made, easy to use, time saving and energy saving and with low cost.In addition, owing to have employed kuppe, kuppe rotates together with rotor, decreases air drag, controls the formation of turbulent flow in centrifugal chamber, noise when greatly reducing centrifugal.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Centrifuge rotor 2 as shown in Figure 1, comprise main shaft 1, rotor 2 and Centrifuge Cup 3, rotor 2 is arranged on main shaft 1, Centrifuge Cup 3 is arranged on rotor 2, rotor 2 is provided with connecting hole, mold insert 4 is inlaid with in connecting hole, main shaft 1 is provided with the keyway 5 matched with mold insert 4, main shaft 1 top is provided with locknut 6, main shaft 1 end is provided with the conical surface section 7 matched with rotor 2, also comprise packed-piston 8 and soft capsule 9, packed-piston 8 is placed in Centrifuge Cup 3, soft capsule 9 is arranged on below packed-piston 8, by rubber, thin-film material is made, soft capsule 9 in adjacent centrifugal cup 3 is communicated with by tube connector, soft capsule 9 is built with the larger liquid of proportion, can be saturated brine or mercury etc., its proportion more can keep rapidly balance more greatly.
During use, rotor 2 is inlaid with mold insert 4, main shaft 1 mills out flat keyway 5, is inserted in keyway 5 by mold insert 4, and locked by the locknut 6 on main shaft 1 top, make rotor 2 be fixed on main shaft 1, ensureing can not relative motion between rotor 2 and main shaft 1.Because rotor 2 and main shaft 1 can not relative motions, in brake process, even if when locknut 6 loosens, rotor 2 also can not come off from main shaft 1, and security performance is high.When in each Centrifuge Cup 3 until centrifugal liquid weight not wait time, the pressure that each packed-piston 8 is subject to is just different, so heavier one side treat the soft capsule 9 of centrifugal liquid by packed-piston 8 depression, high specific gravity liquid in soft capsule 9 just starts to flow to the soft capsule 9 in the Centrifuge Cup 3 glasss of lighter in weight, until each Centrifuge Cup 3 is equal in weight, complete automatic adjustment thus.
