Description
Technical field
The invention belongs to spectral instrument manufacturing technology field, particularly relate to a kind of embedded magnetic and stir constant temperature specimen holder.
Background technology
In the application of nowadays spectrometer, some samples need constantly to stir in its course of dissolution or chemical reaction process for some reason, and current magnetic stirring system can not be put into instrument and use, and so just cannot analyze it and dissolve or course of reaction.Meanwhile, the change of temperature can have an impact to dissolving or course of reaction, so sometimes need temperature control in measuring process, carries out temperature control in this process just needing magnetic to stir.
Summary of the invention
Fundamental purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides a kind of embedded magnetic of compact conformation to stir constant temperature specimen holder.
A kind of embedded magnetic stirs constant temperature specimen holder, it is characterized in that, comprises magnetic stirred sample stand, motor, magnetic holder, button magnet, heat insulating mattress, cell holder, temperature bath frame, shell fragment, sample cell, stirrer, water inlet tap, faucet and valve, described water inlet tap is threaded in the sidepiece of described temperature bath frame and is communicated with its inside, described faucet is threaded in the front portion of described temperature bath frame and is communicated with its inside, described valve is threaded in the side of described magnetic stirred sample stand and is communicated with its inside, described button magnet is at least two, described button magnet is evenly embedded on the ring side face of described magnetic holder, described magnetic holder is fixed on the output shaft of described motor, described motor is fixed by screws in described magnetic stirred sample stand, described cell holder and described heat insulating mattress are fixed by screws in described magnetic and stir on constant temperature sample stand, described stirrer is placed in described sample cell, described sample cell inserts in described temperature bath frame, described shell fragment is fixed in the endoporus of described temperature bath frame by screw.
The invention has the beneficial effects as follows: by control step electric machine rotation, drive magnetic holder and the button magnet rotors inlayed thereof, form rotating magnetic field, thus drive the stirrer in sample cell to rotate by magnetic field induction, realize the stirring to sample.Isothermal liquid (water or oil) flows into temperature bath frame by a water nozzle, flow out from another water nozzle, isothermal liquid flows at temperature bath frame, due to heat conducting effect, thus realize temperature control to temperature bath frame, like this by the temperature realization that the controls isothermal liquid temperature control to the sample of sample cell and inside thereof.Simplicity of design of the present invention, compact conformation, take up room very little, be suitable for being placed in the light path of instrument, and can realize stirring sample simultaneously and measuring, implementation procedure monitoring under the condition of temperature control.

Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of embedded magnetic stirs constant temperature specimen holder, comprise magnetic and stir constant temperature sample stand 1, motor 3, magnetic holder 4, button magnet 5, button magnet 16, heat insulating mattress 6, cell holder 10, faucet 11, temperature bath frame 9, shell fragment 8, shell fragment 12, sample cell 17, stirrer 18, valve 2, described button magnet 5 and button magnet 16 are embedded in described magnetic holder 4, described magnetic holder 4 is fixed on the output shaft of described motor 3, described motor 3 is fixed on described magnetic by screw 13 and stirs in constant temperature sample stand 1, described shell fragment is fixed on described temperature bath frame 9 by screw 14, described faucet 11 is fixed on described temperature bath frame 1, described cell holder 10 is fixed on described temperature bath frame 9 times, described cell holder 10 and described heat insulating mattress 6 are fixed on described magnetic by screw 15 and stir on constant temperature sample stand 1, described valve 2 is fixed on described magnetic and stirs on constant temperature sample stand 1.Described stirrer 18 is placed in described sample cell 17, during work, described sample cell 17 to be inserted in described temperature bath frame 9.
By the rotation of control step motor 3, drive magnetic holder 4 and the button magnet 5 inlayed and button magnet 16 thereof to rotate, form rotating magnetic field, thus drive the stirrer 18 in sample cell 17 to rotate by magnetic field induction, realize the stirring to sample.Isothermal liquid (water or oil) flows into temperature bath frame by water nozzle 7, flow out from faucet 11, isothermal liquid flows at temperature bath frame, due to heat conducting effect, thus realize temperature control to temperature bath frame 9, like this by the temperature realization that the controls isothermal liquid temperature control to the sample of sample cell 17 and inside thereof.When isothermal liquid temperature is lower than environment temperature, the sample temperature of temperature bath frame 9, sample cell 17 and inside will lower than environment temperature, condense the globule like this on temperature bath frame 9 and sample cell 17, passes into dry air can prevent the moisture air from condensing at temperature bath frame 9 and sample cell 17 from valve 2.Simplicity of design of the present invention, compact conformation, take up room very little, be suitable for being placed in the light path of instrument, and can realize efficiently and accurately to the measurement of sample, avoids temperature variation on the impact of sample simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
