The specific embodiment
Like Fig. 1 and shown in Figure 2, this embodiment stirring and evenly mixing device comprises hollow shaft 1, support 4, belt gear 7, motor 8 and puddler 6.This hollow shaft 1 is a tubular body; It has internal perisporium 100 and periphery wall 101, and this internal perisporium 100 defines an axocoel 102 that runs through at first direction, this axocoel 102 and this hollow shaft 1 coaxial line; This first direction direction shown in arrow among Fig. 1, this direction are vertical direction.The upper and lower of the periphery wall 101 of hollow shaft 1 all is equipped with ball bearing 3; The inner ring of these two ball bearings 3 all overlaps the periphery wall 101 of this hollow shaft 1 admittedly; The outer ring of these two ball bearings 3 is all fixing with this support 4, makes these support 4 rotations relatively of this hollow shaft 1.This belt gear 7 comprises first belt wheel 700, belt 701 and second belt wheel 702; This first belt wheel 700 is coaxial to be solidly set on the motor shaft 81 of this motor 8; This second belt wheel 702 is coaxial to be solidly set on the middle part of this hollow shaft 1 periphery wall 101; This belt 701 stretches tight on this first belt wheel 700 and second belt wheel 702, the parallel axes of the axis of this first belt wheel 700 and second belt wheel 702, the parallel axes of the axis of this motor shaft 81 and this hollow shaft 1.Be provided with packing ring 2 between the ball bearing 3 on hollow shaft periphery wall 101 tops and second belt wheel 702, this packing ring 2 is enclosed within on the periphery wall 101 of this hollow shaft.Also be provided with packing ring 2 between the ball bearing 3 of this hollow shaft periphery wall bottom and second belt wheel 702, this packing ring 2 also is enclosed within on the periphery wall 101 of this hollow shaft.In order to prevent that the foreign particles on the ball bearing 3 from falling into reaction tank 10, the below that is positioned at the bearing 3 of hollow shaft periphery wall bottom is provided with door 5, and this door 5 entangles the periphery wall 101 of this hollow shaft and fixes with support 4.Packing ring 2, bearing 3, support 4 and door 5 play the effect of location, fixation hollow axle 1, make hollow shaft 1 above reaction tank 10, freely to rotate.
During installation, the location through packing ring 2, bearing 3, support 4 and door 5 and fixing, with hollow shaft 1 be fixed on reaction tank 10 directly over, and make hollow shaft 1 and reaction tank 10 coaxial lines.The puddler 6 that is fixed on hollow shaft bottom vertically extend in the reaction tank 10, stirring vane 14 try one's best reaction tank 10 the bottom but directly do not contact with this bottom.Motor 8 is used to provide power, and this motor 8 is installed in hollow shaft 1 one sides, and is connected with hollow shaft 1 through belt gear 7.
During work, reagent gets into from the reagent of reaction tank inlet 11, and sampling needle 9 moves to the axis place of hollow shaft 1, vertically moves down then, passes the axocoel 102 of hollow shaft and enters into reaction tank 10.After sampling needle 9 is injected into sample in the reaction tank 10; Move vertically and leave reaction tank 10; At this moment motor 8 energisings through belt gear 7, drive hollow shaft 1 and rotate around same rotation with puddler 6; Sample in the reaction tank 10 and reagent are stirred, at last the outlet 12 through reaction tank of the sample of mixing is transported to existing response measurement passage.
In this embodiment, hollow shaft has the axocoel that runs through at first direction, makes sampling needle and hollow shaft mutually noninterfere.Motor is connected with this hollow shaft through transmission mechanism, thus with the transmission of power of motor to being fixed on the puddler on the hollow shaft.In addition, because hollow shaft has the axocoel that runs through at first direction, it is empty making on the axis of hollow shaft, and sampling needle can pass this hollow shaft and enter into reaction tank along this axis.
In this embodiment, motor is connected with hollow shaft through transmission mechanism, makes the axis of the installation site of motor away from hollow shaft, leaves the space of reaction tank top for sampling needle and gets into reaction tank, this transmission mechanism such as belt gear.Certainly, this transmission mechanism also can be gear drive, Worm and worm-wheel gearing, or other can realize that the transmission of power with power source (like motor) output arrives the transmission mechanism of hollow shaft.
In this embodiment,, make the link position of puddler and hollow shaft be positioned at the edge of hollow shaft, rather than on the axis of hollow shaft, when sampling needle entering reaction tank, it can guarantee puddler and sampling needle mutually noninterfere because hollow shaft runs through at first direction.Certainly, puddler can be fixed on other position that can satisfy with sampling needle mutually noninterfere requirement as requested.
In this embodiment, puddler comprises two connecting rods and is fixed on the stirring vane of this two connecting rods bottom, this stirring vane be shaped as rectangle.Certainly, the quantity of this connecting rod also can be one or more.The shape of this stirring vane 14 also can be the geometry of applying reaction tank bottom, and is as shown in Figure 3; Or fan blade shape, as shown in Figure 4; Or geometry such as ellipse; The quantity of this stirring vane also can be two or more; This puddler 6 also can have two or more that separate setting, and is as shown in Figure 5.For this puddler, it is fixed on the hollow shaft and with hollow shaft and rotates around same rotation, and this puddler is positioned at outside the movement locus of sampling needle, and promptly sampling needle is when the first direction motion moves up and down, and it can not interfered with puddler.
In this embodiment, the axis of hollow shaft, the axis of axocoel and rotation overlap, and sampling needle also is along this axial-movement, and the direction of these axis is consistent with first direction.Certainly, each axis also can not overlap but direction is consistent with first direction, and sampling needle can move along first direction but can move along these axis.On the movement locus of sampling needle, it is not interfered with hollow shaft and puddler.
In this embodiment, hollow shaft is supported on the support through bearing is rotatable.Certainly, also support can be set, and directly hollow shaft and puddler rotates around the common axis of rotation line by the transmission mechanism band.
This stirring and evenly mixing device can be applied in and utilize sampling needle to divide in the type of various blood cell analyzers of blood, as the rabbling mechanism of each reaction tank.Need stirring and evenly mixing device at some but the place of conflicting is spatially arranged, also can utilize the contradiction on this device solves space with other mechanisms or device parts.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
