Can be fixed on the stirrer of electrolytic cell bottom
Technical field
The utility model relates to a kind of electrolytic cell, is specifically related to a kind of stirrer that is fixed on the electrolytic cell bottom.
Background technology
At present, most stirrers are that the magnetize ferrite bar casting shell of the utmost point of a two forms, the rotation of stirrer two blocks of magnet by the motor band in the agitator and two pairs of magnetic poles of stirrer formation change, because stirrer floats in the electrolytic cell bottom, in use exist rotary speed unstabilization, phenomenon such as step-out midway, stirrer is easy to jump and gets up to bend electrode like this, forms electric pole short circuit, causes equipment fault not use.Rotary speed unstabilization makes indicator electrode can not follow the tracks of the judgement terminal point timely, causes the reappearance of test bad, causes result error bigger, makes the result of laboratory test failure.
Summary of the invention
In order to address the above problem, the utility model provides a kind of stirrer that is fixed on the electrolytic cell bottom.
The utility model is achieved by the following technical solution: a kind of stirrer that is fixed on electrolytic cell bottom, comprise stirrer, and stirrer has and is evenly and at least two blades that are symmetrically distributed, and in each blade magnetic pole is installed; Center at stirrer is equipped with fixed axis, and stirrer can be the center rotation with the fixed axis; The fixed axis lower end is fixed on the electrolytic cell bottom.
The center of stirrer is provided with a circular hole that matches with fixed axis, and fixed axis is inserted in the circular hole, and its upper end is provided with the location and uses fixation clamp, its lower end to be fixed on the electrolytic cell bottom.
A kind of stirrer that is fixed on electrolytic cell bottom comprises stirrer, and stirrer has and is evenly and at least two blades that are symmetrically distributed, and in each blade magnetic pole is installed; In the center of stirrer the rotating shaft that is fixed together with stirrer is installed, rotating shaft is installed in the electrolytic cell bottom by axle sleeve and can rotates in axle sleeve.
Good effect of the present utility model is: the utility model is simple in structure, easy to operate, can not appear at the phenomenon that spring gets up to break electrode in the rotation, potentiometer on the agitator is transferred soon also not can step-out, and rotating speed is more stable, and indicator electrode can in time be judged terminal point, make result of laboratory test that reappearance preferably be arranged, improve precision, the degree of accuracy of chemical examination, improved operating efficiency greatly, reduced unnecessary waste.

Fig. 4 is another example structure schematic diagram of the utility model.
Among the figure: 1, stirrer, 2, fixed axis, 3, magnetic pole, 4, fixation clamp, 5, rotating shaft, 6, axle sleeve.
The specific embodiment
As shown in Figure 1 and Figure 2, stirrer 1 is provided with and is evenly and six blades that are symmetrically distributed, and near in the top of each blade magnetic pole 3 is being installed.In the center of stirrer 1 fixed axis 2 is installed.In the present embodiment, be provided with a circular hole that matches with fixed axis 2 in the center of stirrer 1, fixed axis 2 is inserted in the circular hole, and its upper end is provided with fixation clamp 4 with stirrer 1 location.The lower end of fixed axis 2 is fixed on the electrolytic cell bottom.
As shown in Figure 4, the rotating shaft 5 that is fixed together with stirrer 1 is installed in the center of stirrer 1, rotating shaft 5 is installed in the electrolytic cell bottom by axle sleeve 6 and can rotates in axle sleeve 6.
As shown in Figure 3, in use, stirrer is fixed on the bottom of electrolytic cell, under the effect of agitator, stirrer 1 can be center rotation with fixed axis or rotating shaft, can not appear at the phenomenon that springs gets up to break electrode in the rotation, and the potentiometer accent on the agitator soon can step-out yet, rotating speed is more stable, indicator electrode can in time be judged terminal point, makes result of laboratory test that reappearance preferably be arranged, and has improved precision, the degree of accuracy of chemical examination, improve operating efficiency greatly, reduced unnecessary waste.
