Description
Technical field
The utility model relates to instrument field, in particular to a kind of heating bath magnetic stirring apparatus.
Background technique
Magnetic stirring apparatus is the Laboratory Instruments for liquid mixing, is mainly used for stirring or heating stirring is low sticky simultaneously
The liquid or solidliquid mixture of degree.The basic principle is that being pushed away using the magnetic field principle that identical charges repel each other, there is a natural attraction between the sexes using magnetic field
Magnetic stirrer carries out circumferential running in a reservoir for dynamic placement, to achieve the purpose that stir liquid.Cooperate heating temperature
Control system can heat according to specific requirement of experiment and control sample temperature, temperature condition needed for maintaining experiment condition,
Guarantee that liquid mixing reaches experiment demand.
But magnetic stirring apparatus in the prior art, under stirrer drives in magnetic field, inertia is larger, the stirrer in stirring
It is easy to hit wall of cup, cup body offset is caused even to turn on one's side, the bottom wall of stirrer and cup body is kept in contact state, can exist biggish
Friction is easy to also result in the waste of the energy while scratching cup body, in addition, stirring bottom when stirring since stirrer is smaller
The mixing effect of liquid that is more uniform but being located above is mixed with regard to poor, furthermore, since magnetic stirring apparatus is carried out directly to cup body
Heating is connect, although there is the drive of stirrer, heating still not enough uniformly, causes upper and lower temperature difference larger, influences experimental precision,
For some high accuracy experiments, it is clear that requirement of experiment is not achieved.
Summary of the invention
The utility model provides a kind of heating bath magnetic stirring apparatus, can solve problem pointed in background technique.
A kind of heating bath magnetic stirring apparatus, including magnetic base, further include heating bath seat and stirring rod, and the heating bath seat tool has one
For accommodating liquid heating bath, heating tube and the stirrer of solution, the support plate for being used to support instrument, institute are provided in the liquid heating bath
It states and offers several convection holes in support plate, the heating tube is fixed in the support plate, and the stirrer is located at institute
It states below support plate；The stirring rod includes the support portion of tubulose, the circumferential buoyancy being arranged on the lateral wall of the support portion
Paddle and the magnet that buoyancy paddle lower end is arranged in, the buoyancy paddle are made of foamed material.
More preferably, the socket for connecting power supply is provided on the side wall of the heating bath seat, the socket is electrically connected to institute
State heating tube.
More preferably, the heating tube is located at the lower part of the support plate.
The utility model provides a kind of heating bath magnetic stirring apparatus, is heated using heating bath seat to liquid, is then passed through again
The mode of heating bath is treated heating instrument and carries out heating bath and be stirred using stirring rod, makes to be uniformly heated, buoyancy paddle
Can make stirring rod is in suspended state in the solution, resistance is reduced, and since it is not to sink to solution bottom, so that up and down
Available stirring, therefore mixing effect is more preferable, the support portion of tubulose can allow temperature sensor to reach bottom of a cup and not have to
Worry that stirrer hits temperature sensor.

Specific embodiment
As shown in Figure 1 to Figure 3, a kind of heating bath magnetic stirring apparatus provided by the embodiment of the utility model, including magnetic base
10, it further include heating bath seat 20 and stirring rod.
The heating bath seat 20 has liquid heating bath, heating tube 22 and the stirrer 23 for being used to accommodate solution, the liquid heating bath
It is inside provided with the support plate 21 for being used to support instrument, several convection holes 211, the heating tube 22 are offered in the support plate 21
It is fixed in the support plate 21, the stirrer 23 is located at 21 lower section of support plate；
The stirring rod includes that the support portion 30 of tubulose, the circumferential buoyancy being arranged on the lateral wall of the support portion 30 stir
Leaf 31 and the magnet 32 that 31 lower end of buoyancy paddle is set are mixed, the buoyancy paddle 31 is made of foamed material,
For heating tube 22 usually all in bottom, the bottom temp of general beaker can be higher when due to heating, so temperature sensor 40
It generally to be extend into the bottom of a cup of beaker, but the stirrer 23 of traditional magnetic stirring apparatus can be easy to strike temperature sensor
40, and since intermediate position is with through-hole, can accommodate temperature sensor 40 passes through the support portion 30 of tubulose in the present embodiment, side
Just bottom temp is detected.Due to the circumferential setting of buoyancy paddle 31, it can be in and circumferentially rotate under the drive in magnetic field, therefore will not
Strike beaker side wall.
In above scheme, the heating time of heating tube 22, temperature can be controlled using temperature detect switch (TDS) in the prior art
Sensor 40 is connect with temperature detect switch (TDS) signal, and temperature detect switch (TDS) is connect with 22 signal of heating tube, and temperature sensor 40 detects temperature, when
Reaching threshold value makes to send signal to temperature detect switch (TDS), and temperature detect switch (TDS) controls 22 on-off of heating tube.
Further, the socket for connecting power supply, the socket electrical connection are provided on the side wall of the heating bath seat 20
To the heating tube 22.
Further, the heating tube 22 is located at the lower part of the support plate 21.
The utility model provides a kind of heating bath magnetic stirring apparatus, is heated using 20 pairs of liquid of heating bath seat, is then led to again
The mode of bath,hyperthermal is treated heating instrument and carries out heating bath and be stirred using stirring rod, makes to be uniformly heated, buoyancy stirring
Leaf 31 can make stirring rod in the solution be in suspended state, reduce resistance, and due to its be not sink to solution bottom so that on
Under available stirring, therefore mixing effect is more preferable, and the support portion 30 of tubulose can allow temperature sensor 40 reach cup
Bottom and do not have to worry stirrer 23 hit temperature sensor 40.
