Description
Technical Field
The utility model belongs to the technical field of the technique of agitator and specifically relates to a magnetic drive agitator who conveniently tests speed is related to.
Background
At present, a magnetic transmission stirrer is a device which drives a stirring shaft to rotate by utilizing magnetic force so as to force liquid and gas media to convect and uniformly mix.
When the magnetic transmission stirrer is used in the prior art, the stirring shaft is arranged in the reaction kettle, and meanwhile, a certain gap exists between the inner magnet and the outer magnet, so that the rotating speed of the stirring shaft is difficult to measure, and therefore the stirring speed is to be improved.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a magnetic drive agitator who conveniently tests the speed.
The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:
the utility model provides a convenient magnetic drive agitator that tests speed, includes base and the (mixing) shaft that is located the base bottom, be provided with outer magnetism on the base, be provided with interior magnetism on the (mixing) shaft outer wall, its characterized in that: the inner magnet is provided with a notch, a magnetic sensor is arranged on the outer side wall of the stirring shaft and is located in the notch, the magnetic sensor is connected with a controller, the controller is connected with a display screen, and the controller is used for sending a rotating speed value to the display screen based on the magnetic change detected by the magnetic sensor so as to enable the display screen to display the rotating speed value.
The utility model discloses further set up to: a sealing cover is arranged in the base, and the stirring shaft is rotatably arranged in the sealing cover.
The utility model discloses further set up to: and a sealing block is integrally arranged on the outer side wall of the sealing cover.
To sum up, the utility model discloses a beneficial technological effect does:
through setting up breach and magnetic sensor, when the outer magnetism drives the interior magnetism and rotates, the (mixing) shaft rotates, magnetic sensor can measure how many N or S of round this moment, and magnetic sensor gives the controller with the signal transmission who detects, the controller is based on magnetic sensor' S detection quantity and then calculates how many rotations of a minute, the controller sends rotational speed numerical value to the display screen, the staff can be through the audio-visual rotational speed of knowing this moment (mixing) shaft of display screen, be convenient for operate the agitator.
Drawings
Fig. 1 is a schematic view of a magnetic stirrer with a convenient speed measurement according to an embodiment of the present disclosure.
In the figure, 1, a base; 2. a stirring shaft; 3. external magnetism; 4. internal magnetism; 5. a notch; 6. a magnetic sensor; 7. a sealing cover; 8. and (6) sealing the block.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Refer to fig. 1, do the utility model discloses a magnetic drive agitator who conveniently tests speed, including base 1 with be located the (mixing) shaft 2 of base 1 bottom, be provided with outer magnetism 3 on the base 1, be provided with interior magnetism 4 on the (mixing) shaft 2 outer wall. Inner magnetism 4 cover establish on (mixing) shaft 2 and with (mixing) shaft 2 between fixed connection, seted up breach 5 on inner magnetism 4, there is magnetic sensor 6 through bolt fixed mounting on the lateral wall of (mixing) shaft 2, magnetic sensor 6 is located breach 5. Magnetic sensor 6 is connected with the controller through wireless mode, and the controller is connected with the display screen, and the controller is used for sending rotational speed numerical value to the display screen based on the magnetism change that magnetic sensor 6 detected, so that the display screen shows rotational speed numerical value, and in this embodiment, the display can be installed in the position of arbitrary convenient observation.
Referring to fig. 1, a sealing cover 7 is fixedly arranged in a base 1 through bolts, a stirring shaft 2 is rotatably arranged in the sealing cover 7, a sealing block 8 is integrally arranged on the outer side wall of the sealing cover 7, the sealing block 8 increases the sealing performance of the sealing cover 7, the situation that liquid in a reaction kettle enters the base 1 is reduced, and the sealing performance of the magnetic transmission stirrer is improved.
The implementation principle of the embodiment is as follows: when outer magnetism 3 drives interior magnetism 4 through magnetism and rotates, interior magnetism 4 drives (mixing) shaft 2 and rotates, magnetism sensor 6 can measure how many a plurality of N or S of round this moment, and magnetism sensor 6 gives the controller with the signal transmission who detects, how many rotations have taken place for a minute is then calculated to the magnetism change quantity of the detection of controller based on magnetism sensor 6, the controller sends rotational speed numerical value to the display screen, the staff can pass through the audio-visual rotational speed of (mixing) shaft 2 this moment of understanding of display screen, be convenient for operate the agitator.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
