Description
Technical field
The utility model relates to a kind of chemical experimental instrument, specifically a kind of chemical experiment extraction equipment.
Background technology
Separatory funnel is extraction equipment the most frequently used in chemical industry.During extraction, need first will the solvent of separatory to be needed to pour in separatory funnel, then with hand-held firmly separatory funnel, vibration solution, separatory after standing certain hour, easily produce gas for volatile solvent soln when rocking, the deflation course that causes drawing the cork may occur that solution goes out the phenomenon of separatory funnel, not only have impact on the experiment degree of accuracy but also existed operating personnel's personal safety to threaten; The effect of extracting temperature influence of some solution, and existing separatory funnel is not easy to heating; Some liquid is high due to its viscosity, adds the reason of pressure in funnel, and when being separated to liquid level layering critical surface, flow velocity is excessively slow, separatory difficulty; Its cock of the separatory funnel of prior art and fistulae easily in use damage, and often just cause whole separatory funnel and scrap, use cost is high, easily causes waste;
Utility model content
The chemical experiment extraction equipment that the purpose of this utility model is to provide a kind of to be convenient to heat, security is high, simple to operate, can reduce use cost, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of chemical experiment extraction equipment, comprise bracing frame and separatory funnel, support frame as described above comprises base, support bar and clamping device, and base is vertically provided with support bar, and support bar top has clamped clamping device; The pinch zones of described clamping device is set to inverted circular cone shape, and the inwall of clamping device is for being provided with heating jacket; Described separatory funnel is fixed on bracing frame by clamping device, and separatory funnel comprises glass stopper, bucket body and fistulae, is provided with spiral coil in glass stopper, and the import of spiral coil is opened in the side of glass stopper, and outlet is opened in the bottom of glass stopper; Described bucket body bottom is provided with external screw thread, fistulae top is provided with the internal thread with external screw thread adaptation, fistulae and bucket body are sealed by internal thread and external screw thread and screw, cock is provided with in the middle part of described fistulae, cock bottom is provided with syringe, described syringe is made up of the foraminate syringe of front end band and the piston core bar matched and piston handle, and described syringe is connected with fistulae.
As further program of the utility model: described heating jacket comprises the first insulating barrier, zone of heating and the second insulating barrier that set gradually from outside to inside.
As the utility model further scheme: be provided with heat-reflecting layer between described zone of heating and the second insulating barrier, described heating jacket is provided with temperature-adjusting device, and temperature-adjusting device is arranged on the side of clamping device.
As the utility model further scheme: described glass stopper, bucket body and fistulae adopt polypropylene material to make; Cock adopts polytetrafluoroethylene (PTFE) material to make.
Compared with prior art, the beneficial effects of the utility model are: the utility model can fully meet extraction experiments requirement, can heat, control heating-up temperature, separatory is effective to extract in separatory funnel; Glass stopper part is provided with spiral coil, avoid and rock the situation that separatory funnel process need extracts glass stopper repeatedly, and the gas in funnel diffuses to outside separatory funnel by spiral coil, avoid solution when extracting glass stopper and go out the situation of separatory funnel because of air pressure, ensure that the accuracy of experiment and the personal safety of operating personnel; Split-type design is convenient to carry out local replacing when fistulae damages, and more saves cost, avoids waste; Syringe the separation that can be conducive to the high liquid of viscosity is set, two-phase laminated flow is more accurate, avoids the error that manual rotation knob causes, accelerates separatory speed.
