Abstract
The utility model relates to a stirring device, particularly a reciprocating and applying electric stirrer which is applied to the sample stir in the particle size test procedure of a laser particle size distribution instrument. The utility model comprises a motor, an operating mechanism and a sample cell, wherein the operating mechanism comprises a driving wheel, a connecting rod, a square shaft, a pressure ring and a stirring handle, the motor is arranged on the outer side at the lower end of a shell body and the driving wheel and the connecting rod are arranged in the shell body. The driving wheel is installed on the inner wall of the shell body, is connected with the motor and is connected with the connecting rod. The upper end of the shell body is provided with a hole. One end of the square shaft is inserted in the shell body by the hole and is connected with the connecting rod, and the other end is positioned out of the shell body and is provided with the pressure ring. One end of the stirring handle is connected with the square shaft by the pressure ring, and the other end is inserted in the sample cell. The utility model drives the stirring handle to move to and fro by the square shaft, therefore suspension liquid always exists in the homogeneous state in the state of automatic stir. Good stirring effect is achieved, no dead angle exists, adverse effects on the sample can not be generated and bubbles can not be generated.
Description
Technical field
The utility model relates to a kind of agitating device, the reciprocal application formula electric mixer that particularly be applied in the laser particle size distribution instrument testing graininess process, sample stirs.
Background technology
In laser method testing graininess process, need the suspension in the sample cell to remain uniform state.Because the volume of sample cell is less, is shaped as cuboid, therefore can't use general rotating spoon.The sample of existing laser particle size distribution instrument stirs dual mode, and a kind of is manual stirring, and another kind is a magnetic agitation.When manually stirring, labor intensity of operating personnel is big, and is discontinuous to the sample stirring, is easy to generate bubble in the sample cell, because handle in the instrument outside, therefore can influence the sealing effectiveness of instrument integral body.And magnetic agitation to sample stir inhomogeneously, insufficient, the dead angle is arranged.In addition, magnetic agitation also can be influential to sample particle, as ferromagnetic particle is had magnetization.So the sample alr mode of existing two kinds of laser particle size distribution instrument all produces adverse influence to the overall performance of laser particle analyzer.
The utility model content
In order to solve above-mentioned weak point, it is a kind of in laser particle size distribution instrument testing graininess process that the purpose of this utility model is to provide, and can keep suspension in the sample cell to be in the reciprocating motor agitator of uniform state all the time.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises motor, executing agency and sample cell, and wherein executing agency comprises driving wheel, connecting rod, square shaft, pressure ring, raker stirrer; Motor is installed in the outside of housing lower end, and driving wheel, connecting rod are located at the inside of housing, and driving wheel is installed on the inwall of housing and with motor and is connected, and is connected with connecting rod on the driving wheel; The upper end of housing has the hole, and an end of square shaft inserts in the housing by the hole and is connected with connecting rod, and the other end is positioned at outside the housing, which is provided with pressure ring, and an end of raker stirrer is connected with square shaft by pressure ring, and the other end inserts in the sample cell.
Wherein: the upper end of housing is provided with groove, and sample cell places in the groove; Connecting rod off-centre is connected on the driving wheel.
Advantage of the present utility model and good effect are:
1. mixing effect is good.The utility model drives raker stirrer by square shaft and moves back and forth, thereby making suspension be in uniform state all the time under the stirring automatically, reaches good mixing effect.
2. do not have the dead angle, can not have a negative impact, do not produce bubble sample.The dead angle is not stayed in the automatic stirring of the utility model, and sample without any influence, is stirred continuously, do not have bubble to produce.
3. instrument good sealing effect.The utility model is placed on the inside of laser particle analyzer, and stir automatically the energising back, helps the sealing of instrument.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model power section.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model comprises motor 1, executing agency and sample cell 7, and wherein executing agency comprises driving wheel 2, connecting rod 3, square shaft 4, pressure ring 5, raker stirrer 6; Motor 1 is installed in the outside of housing 8 lower ends, and the upper end of housing 8 is provided with groove, and sample cell 7 places in the groove.Driving wheel 2, connecting rod 3 are located at the inside of housing 8, and driving wheel 2 is installed on the inwall of housing 8 and with motor 1 and is connected, and is connected with connecting rod 3 on the driving wheel 2, and connecting rod 3 off-centre are connected on the driving wheel 2; The upper end of housing 8 has the hole, and an end of square shaft 4 inserts in the housing 8 by the hole and is connected with connecting rod 3, and the other end is positioned at outside the housing 8, which is provided with pressure ring 5, and an end of raker stirrer 6 is connected with square shaft 4 by pressure ring 5, and the other end inserts in the sample cell 7.
During use, earlier sample cell 7 is put into the groove on the housing 8, again raker stirrer 6 is put in the sample cell 7, and raker stirrer 6 and square shaft 4 is coupled together with pressure ring 5.Then the utility model is put into laser particle analyzer inside.After turning on the power switch, motor 1 is switched on and is rotated, and drive driving wheel 2 and rotate, 3 motions of driving wheel 2 drivening rods, connecting rod 3 and then drive square shaft 4 move reciprocatingly.Along with the reciprocating motion of square shaft 4, be connected in the liquid of raker stirrer in sample cell 7 on the square shaft 4 and move reciprocatingly, thereby make suspension be in uniform state all the time under the stirring automatically.Powered-down switch behind the EOT takes out the utility model from laser particle analyzer is inner, unload raker stirrer 6, takes out sample cell 7 and gets final product.
