Abstract

The utility model discloses a separating funnel with a gas operated device, which is composed of a funnel body 1, a funnel pipe 2 and a switch 6, the outer side of the funnel pipe 2 is provided with a bushing 3, the upper port of the bushing 3 and the outer wall of the funnel pipe 2 are fixed into one body, the lower port of the bushing 3 shows a pyramidal shape, a gas inlet hole 4 is arranged on the lower port wall of the bushing 3, and a gas outlet branch pipe 5 is disposed at the upper part of the bushing 3. The separating funnel with the gas operated device has advantages of simple structure, convenient operation and safe use, and can be widely used in the assembling of a gas generator in the education in chemistry and matched for adding liquid and reagent and guiding out gases.

Description

The separating funnel of band gas operated device

Technical field

The utility model relates to a kind of improvement of separating funnel, and specifically a kind of separating funnel with gas operated device is applicable to that assembling gas generator, work add the instrument of liquid and reagent and derivation gas.

Background technology

In chemical experiment teaching, at the assembling gas generator, do to add in the instrument of liquid and reagent and derivation gas, generally to use separating funnel, this separating funnel has bell mouth, fistulae, switch constitutes, during use, to on the sealing plug of bottleneck, make a call to two holes, insert fistulae in the hole, insert air guide glass bend pipe in another hole, derive gas in the bottle, this separating funnel separates with air guide glass bend pipe, its weak point is: operation is wasted time and energy, and dangerous, in intubate or bend pipe process, because the air guide glass tube is easily broken, often stab the finger of operating personal.

Summary of the invention

The purpose of this utility model is to provide the separating funnel of a kind of operation simple in structure, easy, band gas operated device safe in utilization.

For reaching above purpose, the technical scheme that the utility model adopted is: the separating funnel of this band gas operated device, constitute by funnel bucket body, fistulae, switch, it is characterized in that establishing sleeve pipe in the outside of fistulae, suitable for reading and the fistulae outer wall of sleeve pipe is fixed as one, and the end opening of sleeve pipe is the centrum shape, so that insert in the bottle stopper of bottleneck, on the end opening wall of sleeve pipe, establish induction opening, set out gas branch pipe on the top of sleeve pipe.The utility model is also implemented by following measure: described sleeve pipe inwall suitable for reading is a ground-glass appearance, be beneficial to sealing, the length of sleeve pipe is 2-4cm, distance between the inwall of sleeve pipe and the outer wall of fistulae is 0.1-0.2cm, the outer wall of fistulae is a ground-glass appearance, length is 8-10cm, can once be fixed as an integral body with sleeve pipe.When using the utility model, can make a call to a hole beyond the Great Wall at flask, fistulae is inserted, it is inserted into the sleeve pipe position and gets final product.

The beneficial effects of the utility model are: simple in structure, easy to operate, safe in utilization, can be widely used in the assembling of gas generator in the chemistry teaching, and adapted when doing to add liquid and reagent and derivation gas.
