Description
Technical Field
The utility model belongs to the technical field of chemistry experiment agitating unit, especially, relate to a mechanical stirring device is used in portable totally closed organic chemistry experiment.
Background
Currently, the current state of the art commonly used in the industry is such that: in the organic chemistry experiment process, a lot of reactions are carried out because materials are solid-liquid mixtures or products are viscous, in order to better mix uniformly or dissipate heat, a mode of stirring while reacting is needed, and at present, a laboratory generally adopts mechanical stirring or magnetic stirring. If the viscosity of the reaction system is higher, the effect of magnetic stirring is poorer; if the heating temperature is required to be controlled, no matter the heating is carried out by using a water bath, an oil bath or an air bath, the common magnetic stirrer cannot play a good effect easily.
Mechanical stirring is generally adopted when the viscosity of a reaction system is high and temperature control is needed, but the phenomenon of poor sealing generally exists in the current mechanical stirrer in a laboratory. The current mechanical stirrer consists of a speed regulator and a stirring motor, wherein the speed regulator is connected with alternating current, the rotating speed is controlled by a resistor, the stirring motor is connected with the stirring motor through a contact pin type interface, the stirring motor is supported by an iron support, one end of the stirring rod is connected with a stirring rod, the stirring rod is generally about 20cm long and extends into a glass flask for stirring, because the stirring rod needs to rotate, the rod and the glass flask cannot be sealed, if the stirring rod is plugged by a plug, the stirring rod cannot be limited to rotate, the plug is not needed, the gas can be volatilized in a large amount when the substance smell in a reaction system is large and even toxic components exist, and most organic matters have the characteristic of easy combustion, the experiment environment cannot be closed completely, so that the experiment environment is severe, and great potential safety hazard also exists. In addition to poor sealing, such mixers are bulky, heavy and expensive.
It is proposed to use a water sealing device, i.e. two glass sleeves which are mutually inverted are sleeved on a stirring rod, the gas in the sleeves is blocked from escaping from a glass bottle by water, but the stirring rod can rotate and can not be completely sealed, so that the method only can reduce the gas escaping and can not realize full sealing. Such a method is not reported in the patent. The mechanical stirring sealing device in the prior patent technology is characterized in that a rubber tube is connected with a syringe piston cylinder and a stirring rod on a traditional mechanical stirrer, and a joint is fastened by a thin iron wire; if the iron wire is not tightly tied, air leakage can occur, so that the mechanical stirring rod which is too tightly tied can not rotate, and the embarrassing situation that the tightness is not ensured can occur.
In summary, the problems of the prior art are as follows:
(1) the existing magnetic stirrer has poor effect on stirring a system with high viscosity.
(2) The existing mechanical stirrer has poor sealing property.
(3) The mechanical stirring sealing device in the prior art only adds the improvement in the aspect of sealing on the original mechanical stirrer, has poor effect, and does not change the characteristics of large volume, wide occupied area, inconvenient carrying and high price of the existing mechanical stirrer.
The difficulty and significance for solving the technical problems are as follows: the magnetic stirrer has good sealing performance, but the system with high stirring viscosity has poor effect; the existing mechanical stirrer has good stirring performance, but poor sealing performance; adopt this patent the portable agitator of mechanical type overcoat spiral plug's form has still had fabulous leakproofness when having guaranteed the stirring effect promptly.
