Description
Technical field
This utility model relates to solid-liquid separation technique, particularly to a kind of centrifuge.
Background technology
Centrifugation technique, is a kind of material making proportion different by centrifugal force method of carrying out separating, and its correlated process is: owing to the equipment such as centrifuge can produce at a relatively high angular velocity, makes centrifugal force be much larger than gravity, and then the float in solution is convenient to Precipitation；Centrifugal force suffered by the different material of proportion is different again, thus sedimentation velocity is different, and the material that proportion can be made different reaches separation.Centrifugal, as a kind of conventional separation and extraction technology, it is widely used to the fields such as biology, medicine and pharmacology and chemistry.
The Chinese patent that Authorization Notice No. is CN204799426U, authorized announcement date is on November 25th, 2015 discloses a kind of low speed centrifuge, this low speed centrifuge includes body, cover, motor and centrifugal frame, described cover one side is turnover to be arranged on body, described motor is arranged on organism bottom, described motor top is provided with rotating shaft, is provided with shaft hole at described centrifugal frame bottom centre；Together with the upper end of described rotating shaft is fixedly installed with centrifugal frame by shaft hole；Described centrifugal frame periphery is angularly evenly arranged with some fixed covers, described fixed cover and the bottom surface of centrifugal frame are that certain angle of inclination is arranged, pillar on centrifuge tube it is fixedly installed in fixed cover, on described centrifuge tube, the lower end of pillar is provided with pillar under centrifuge tube, and under described centrifuge tube, pillar can slide up and down relative to pillar on centrifuge tube.
Research finds, when the size of centrifuge tube and fixed cover is not mated, in centrifugal process there is the probability of relative motion in centrifuge tube and fixed cover, the centrifuge tube collision fixed cover of high-speed motion, cause the vibration of centrifuge tube, centrifugal absorption fixing on tube wall is shaken to liquid again, affects centrifugal effect.Therefore develop a kind of centrifuge reducing centrifuge tube and fixed cover relative motion and there is certain production application value.
Utility model content
The purpose of this utility model is to provide a kind of centrifuge, which solves centrifuge tube and the problem of installing rack generation relative motion, has minimizing centrifuge tube and the effect of installing rack relative motion.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of centrifuge, including body and the working chamber being located in body, described organism bottom is provided with centrifugal motor, the motor shaft of described centrifugal motor is provided with installing rack, equidistantly it is provided with several in the circumference of described installing rack to be gradually reduced to the bottom of lock chamber for the top in the distance self-retaining chamber between the lock chamber placing centrifuge tube, the cavity wall of described lock chamber；The mounting groove of outer rim for placing centrifuge tube it is provided with at the lock chamber on described installing rack.
Use said structure, when centrifuge tube stretches in lock chamber, owing to the top in the distance self-retaining chamber between the cavity wall of lock chamber is gradually reduced to the bottom of lock chamber, after centrifuge tube stretches into a certain distance, the cavity wall of lock chamber can clamp centrifuge tube, reduces centrifuge tube and the relative movement of installing rack；Utilize the mounting groove fixing axially-movable reducing centrifuge tube to the outer rim of centrifuge tube simultaneously；To sum up, the relative motion of centrifuge tube and installing rack can be reduced, reduce centrifuge tube and installing rack collides the situation causing centrifugal effect difference, the situation of the frictional heat that simultaneously can reduce both makes centrifuge tube can keep constant temperature in centrifugal process, reduce temperature and the sample in centrifuge tube is centrifuged the impact caused, can further improve the quality of the product of separating effect and separation.
More preferably: in the cavity wall of described lock chamber, be axially arranged with elastic extruding bar.
Said structure, elastic extruding bar is used to have certain squeezing action to centrifuge tube, consolidate the annexation of centrifuge tube and installing rack further.
More preferably: the removable fixing lid being provided with for opening and closing lock chamber on described installing rack.
Use said structure, reduce the probability that in centrifugal process, centrifuge tube moves axially.
More preferably: on the described sheathed installing rack of fixing lid and both clampings.
Use said structure, open and close lock chamber the most convenient, work efficiency can be improved；And the annexation after clamping does not goes to pot under the action of the centrifugal, the probability that in centrifugal process, centrifuge tube moves axially can be reduced.
More preferably: side and the installing rack of described fixing lid are hinged, its opposite side and installing rack clamping.
Using said structure, in addition to clamping can achieve the effect that, the effect unique of side hinged side clamping is, only opens joint end and can quickly open fixing lid and can improve work efficiency further.
More preferably: be provided with in described lock chamber and take pipe fitting for ejected by centrifuge tube, described in take pipe fitting and include being placed in the horizontal stripe bottom lock chamber and the vertical bar being connected with horizontal stripe one, lock chamber setting is stretched out in one end of described vertical bar.
Directly from taking out centrifuge tube in lock chamber, centrifuge tube more or less can collide the cavity wall of lock chamber, and uses said structure can alleviate above-mentioned situation；Secondly, the existence of horizontal stripe can also leave the situation that cushion space cannot take out to reduce centrifuge tube to be stuck in the middle and lower part of lock chamber bottom lock chamber and between centrifuge tube；It addition, vertical bar has certain squeezing action to centrifuge tube, it is possible to reduce centrifuge tube and the relative movement of installing rack.
More preferably: the curved setting of cross section of described horizontal stripe and its arrange with centrifuge tube bottom mating.
Use said structure, mate both when taking centrifuge tube, reduce the situation of centrifuge tube landing when taking.
More preferably: the bottom of described lock chamber and installing rack is inclined to set.
Using said structure, centrifugal action has an active force outwards got rid of, and this set of lock chamber can mate with this active force, strengthens centrifugal effect.
In sum, this utility model has the advantages that
The top that distance between the cavity wall of lock chamber is set as self-retaining chamber is gradually reduced to the bottom of lock chamber, is axially arranged with elastic extruding bar and vertical bar simultaneously, clamps centrifuge tube, can reduce the probability that centrifuge tube rotates in lock chamber in the cavity wall of lock chamber；And by fixing lid and the setting of mounting groove, centrifuge tube probability of axially-movable in lock chamber can be reduced, reduce centrifuge tube and installing rack collides the situation causing centrifugal effect difference, the situation of the frictional heat that simultaneously can reduce both makes centrifuge tube can keep constant temperature in centrifugal process, reduce temperature and the sample in centrifuge tube is centrifuged the impact caused, can further improve the quality of the product of separating effect and separation.
