Abstract
A closed device for preparing toxic gas consists of a gas collecting bottle, a tail gas absorption bottle, a tee-junction piston and a latex balloon, wherein a drop funnel is connected with a flask through a guide tube; the inside of the guide tube of the flask is connected with the tee-junction piston in series; a piston is connected with the gas collecting bottle and another tee-junction piston; the tail gas absorption bottle is connected below the piston and has the bottle mouth provided with the latex balloon. The utility model overcomes the disadvantages of uncontrollable reaction velocity and easy leakage of chlorine gas during replacing gas collecting bottle existing in middle school chlorine gas experiment.
Description
The utility model belongs to a kind of instrument and equipment, specifically a kind of instrument and equipment that is used for chemical laboratory.
The chlorine preparation facilities that regulation is arranged in the chemical experiment teaching material of senior middle school, in school, used decades, but there is following weak point in it: 1, when MnO2 and concentrated hydrochloric acid react too fast, a large amount of chlorine makes air pressure increase in the flask, has hindered following smoothly of the concentrated hydrochloric acid in the dropping funel, the uncontrollable reaction speed of operator, react sometimes fast and sometimes slow, it is inhomogeneous to produce air-flow.When air pressure increased to a certain degree in the flask, chlorine regular meeting came up by dropping funel.2, when the full one bottle of chlorine of collection need be changed gas bottle, chlorine will leak, atmosphere pollution.
The purpose of this utility model is: the obturator that a kind of toxic gas preparation that can control, not leak when changing gas bottle is provided.
The purpose of this utility model realizes with the following method: dropping funel and flask are coupled together with conduit, form a linker, make in funnel and the flask air pressure equate that gas can not pour in down a chimney, a speed of liquid also can be controlled, and toxic gas can all be derived by conduit.Serial connection one A stop,threeway is connected to gas bottle under the piston in conduit, and the piston other end joins by conduit and another B stop,threeway, be connected to the tail gas absorption bottle under the piston, the piston other end is connected to gas bottle, and tail gas absorbs on the bottleneck and picks out with a conduit, and pipe end is equipped with latex balloon.
Below in conjunction with accompanying drawing the utility model is further elaborated:
Accompanying drawing is a structure chart of the present utility model.
Referring to figure, on dropping funel 1, link to each other with flask 3 with conduit 2, serial connection one A stop,threeway 5 in flask conduit 4, the piston lower end is connected to gas bottle 7 by conduit 6, the A stop,threeway other end joins by conduit 8 and B stop,threeway 9, is connected to tail gas absorption bottle 10 under the B stop,threeway, and the piston other end is connected to gas bottle, tail gas absorbs on the bottleneck and picks out with a conduit 11, and pipe end is equipped with latex balloon 12.
Claims (1)
1, a kind of obturator of toxic gas preparation, form by gas bottle, tail gas absorption bottle, stop,threeway, latex balloon, it is characterized in that: link to each other serial connection one stop,threeway in the flask conduit above the dropping funel with conduit with flask, the piston lower end is connected to gas bottle by conduit, the stop,threeway other end joins by conduit and another stop,threeway, is connected to the tail gas absorption bottle under the piston, and the piston other end is connected to gas bottle, tail gas absorbs on the bottleneck a conduit, and pipe end is equipped with latex balloon.
