Description
Technical field
The utility model relates to a kind of device that the glass electrode of PH meter is carried out verification of being used for, and belongs to metering calibration technology field.
Background technology
The glass electrode of PH meter needs periodic calibrating just can guarantee the accuracy of measurement result, traditional operational method is that the PH glass electrode is placed the fixing volumetric solution of pH value, one people need hand the PH glass electrode and not stop to stir electrode, the purpose of stirring is to produce flow velocity, thereby the ion activity that improves volumetric solution is (when normally measuring, electrode is to place mobile sample liquid), another people observes secondary souvenir measured value and to its correction.This operational method not only needs multi agent cooperation so that waste time and energy, the ball bubble of PH glass electrode that even more serious is as thin as a wafer, the glass wall thickness only is tens microns, the vessel wall of touching or strike volumetric solution gently promptly can damage.During operation, can only very little dynamics stir, need repeatedly operation to demarcate successfully,, can not avoid glass ball bulb not to be damaged even like this.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of device that needs the one man operation to get final product verification PH meter glass electrode and can stop to damage glass electrode.
The technical solution of the utility model is: a kind of PH meter glass electrode calibration equipment, comprise the chassis, be arranged on motor in the chassis, be positioned on the chassis and rotary bracket that the bottom connects with motor output shaft by shaft coupling and the cantilever shalving that is fixed in chassis one side, be placed with on the described carriage and be used to hold the vessel of demarcating liquid, one end of described cantilever shalving is provided with the securing member that is used to insert PH meter glass electrode, and described securing member is positioned at the top of departing from the vessel center.
When calibration equipment of the present utility model uses, with being housed, the vessel of demarcating liquid place on the carriage, insert in securing member the glass electrode of PH meter fixing, and the head that makes glass electrode stretches in the demarcation liquid of vessel, this moment, glass electrode departed from the center starter motor drive carriage rotation of vessel, vessel and demarcation liquid also rotate, uniform circular motion is made at the relative vessel of glass electrode center, the demarcation liquid of constant rotation promptly flows through the glass ball bulb of glass electrode head, and fully contact and carry out chemical reaction with internal reference electrode in the ball bubble, thereby glass electrode is demarcated the (measured value of observation output, the fixedly pH value of liquid is demarcated in contrast, and the PH meter is carried out corresponding correction).
The beneficial effect of the utility model PH meter glass electrode calibration equipment is: the verification mode of comparing existing PH meter glass electrode provides a kind of special calibration equipment, this calibration equipment is demarcated in the liquid by making fixing glass electrode stretch into constant rotation, because the demarcation liquid stabilization of speed of rotation, the strength that is applied to glass electrode are even, therefore can realize the quick demarcation to glass electrode; And since glass electrode all the time with the sidewall certain distance each other of rotation vessel, therefore can thoroughly stop glass electrode and damage because of being impacted.
Improvement of the technical scheme is: described cantilever shalving forms L shaped by horizontal arm and upright arm; The upright arm of described cantilever shalving is divided into nested each other two-section up and down, its fixing and lifting and rotation relatively by lock tube between two-section up and down.Like this, can further regulate the deflection distance of the relative vessel of glass electrode, demarcate flowing of liquid in glass electrode and the vessel thereby regulate.
The perfect of technique scheme is: described carriage is to be intersected by the supporting plate of two two ends band flangings to constitute cruciform, and the part of described shaft coupling is arranged on the carriage bottom.
Description of drawings
Below in conjunction with accompanying drawing PH meter glass electrode calibration equipment of the present utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment PH meter glass electrode calibration equipment.
Fig. 2 is the structural representation of carriage among Fig. 1.
Movement locus synoptic diagram when Fig. 3 is the use of the utility model embodiment PH meter glass electrode calibration equipment.
Embodiment
Embodiment
The PH meter glass electrode calibration equipment of present embodiment as shown in Figure 1, comprise chassis 1, be arranged on motor 2 in the chassis 1, be positioned on the chassis 1 and rotary bracket 3 that the bottom connects with motor 2 output shafts by shaft coupling 9 and the cantilever shalving 4 that is fixed in chassis 1 one sides, cantilever shalving forms L shaped by horizontal arm 4-1 and upright arm.The structure of carriage 3 is to be intersected by the supporting plate of two two ends band flangings to constitute cruciform as shown in Figure 2, and the part of shaft coupling 9 is arranged on carriage 3 bottoms.Be placed with the vessel 5 that are used to hold demarcation liquid on carriage 3, horizontal arm 4-1 one end of cantilever shalving 4 is provided with the securing member 7 that is used to insert PH meter glass electrode 6, and securing member 7 is positioned at the top of departing from vessel 5 centers.The upright arm of cantilever shalving 4 is divided into nested each other upper and lower two-section 4-2,4-3, and upper and lower two-section 4-2, the 4-3 of upright arm is fixing by lock tube 8, and section following relatively section 4-3 of 4-2 that goes up that can regulate upright arm by degree of tightness lock tube 8 carries out lifting and rotation.
As shown in Figure 3, by the adjustment of distance, the ball bubble that can adjust PH meter glass electrode 6 heads is with respect to the motion girth of demarcating liquid.For example, the ball bubble is when the A of position, produce movement locus 11, the ball bubble is when the B of position, produce movement locus 12, the motion girth of movement locus 11 and movement locus 12 is different, and the ball bubble also changes with the relative flow velocity that flows of demarcating liquid formation thereupon, thereby can change the speed of chemical reaction, satisfy the demand that different model PH meter glass electrode 6 is demarcated.
The various embodiments described above that are not limited to of the present utility model have such as the variation that can infer: 1) upright arm of cantilever shalving 4 makes one section into, removes lock tube 8, and PH meter glass electrode 6 inserts maintenance fixed position in back on the securing member 7; 2) L shaped cantilever shalving 4 also can make C shape, S shape or other shapes into; Or the like.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
