Abstract

The utility model discloses a mini gas generator, which relates to an experimental instrument, in particular to a mini gas generator, which comprises a stand (10), a liquid tank (3), a gas generator (4), a three-way plastic soft pipe (1) and a gas tube (9), the lower outlets of the liquid tank and the gas generator (4) are connected with the three-way plastic soft pipe (1), the third port of the three-way plastic soft pipe (1) is connected with a tail tube switch (2), the branch pipe on the side of the upper end of the gas generator (4) is connected with the gas tube (9) and the switch (7), the liquid tank (3) and the gas generator (4) are bound with a rubber band (5). The three outlets of the three-way plastic soft pipe (1) are connected with the liquid tank (3), the gas generator (4) and the switch (2); the branch pipe on the side of the upper end of the gas generator (4) is served as a outlet of the gas, which is connected with the gas tube (9) and the switch (7). The utility model has the advantages of simple and mini structure, convenient change of reagents, green experiment, which is suitable for the gas generated by the reaction of the solid substance and the liquid substance.

Description

Micro gas generator

Technical field: the utility model is the gas generator that a kind of middle school or college chemical experiment are used, particularly a kind of micro gas generator.

Background technology: at present, chemical experiment is to microminiaturized and greenization direction reform.In middle school or university chemistry education experiment, the usual means that does not add hot preparation gas is a kipp gas generator, the problem that this gas generator exists has: be glass apparatus, and the instrument volume is big, the chemical reagent consumption is more and change weak point such as reagent trouble.

Summary of the invention: be the deficiency of the gas generator that overcomes present use, the gas preparation that the utility model provides a kind of micro gas generator to be used for chemical experiment, its experiment equipment obtains easily, and manufacturing process is simple, and the chemical reagent consumption is less and replacing reagent is convenient.

The technical scheme that its technical matters that solves the utility model adopts: adopt the container of a band arm to make gas generator, the container of a support pipe free is made knapsack, the shape of container and structure are the injector for medical purpose shape, one of rubber stopper, four of plastic flexible pipes, one of threeway plastic flexible pipe, one on bungee, one of test tube clamp, one of iron stand, two on switch, a small amount of asbestos; The lower end that two ports in the threeway plastic flexible pipe (1) is attached at knapsack (3), gas generator (4) exports, and the 3rd port of threeway plastic flexible pipe (1) connects raffinate gate out switch (2).Rubber stopper (8) is clogged the outlet of gas generator (4) upper end, open an arm outlet in the upper side of gas generator (4), the outlet binding is gone up plastic flexible pipe and is made wireway (9) and switch (7), with bungee (5) knapsack (3) and gas generator (4) are held together, clamp the upper end of knapsack (3) with test tube clamp (6), and be fixed on the iron stand (10).

The invention has the beneficial effects as follows: the one, instrumentation is simple, and compact conformation is easy to combination and fractionation; The 2nd, microminiaturized, volume is little, is easy to collection and arrangement; The 3rd, gas generator and knapsack can be used injector for medical purpose, the syringe of making gas generator is done improvement slightly get final product, and experiment equipment obtains easily, and low price reduces the equipment purchase commodity greatly; The 4th, reagent dosage is few, save reagent and experiment fees expenditure, and the refuse amount is few, and environmental pollution is little, realizes the experiment greenization; The 5th, experimental implementation is easy, and the reaction of energy pilot-gas, can replace kipp gas generator; The 6th, be used for the preparation of multiple gases; The 7th, do not disassemble instrument with regard to changing or adding liquid and solid chemicals, easy to operate.

Description of drawings: accompanying drawing is a front view of the present utility model, and code name is respectively among the figure: 1 is the threeway plastic flexible pipe, and 2 is switch, and 3 is knapsack, and 4 is gas generator, and 5 is bungee, and 6 is test tube clamp, and 7 is switch, and 8 is rubber stopper, and 9 is wireway, and 10 is iron stand.

Embodiment of the present utility model: referring to accompanying drawing, three ports with threeway plastic flexible pipe (1) connect knapsack (3), gas generator (4) and switch (2) respectively, rubber stopper (8) is clogged the outlet of gas generator (4) upper end, and the arm outlet of gas generator (4) links goes up wireway (9) and switch (7).With bungee (5) knapsack (3) and gas generator (4) are held together, clamp the upper end of knapsack (3), and be fixed on the iron stand (10) with test tube clamp (6).

Method of operating: one, add chemical reagent: the bottom pad at gas generator (4) is gone up a small amount of asbestos, loads onto solid particle reagent above the asbestos.In knapsack (3), load onto liquid reagent.Two, gas preparation: during use, open switch (7),, the reaction liquid in the knapsack (3) is contacted by three-way hose (1) with solid reagent in the gas generator (4) because of action of pressure, thereby chemical reaction takes place and generate gas, gas is derived by wireway (9).When stopping gas and preparing, close air guide switch (7), can not derive and increase pressure, liquid reactants will be pushed back and contain in the liquid injection tube (3), solid is no longer contacted with liquid reagent and stop reaction owing to the gas that produces in the gas generator (4).Next time is when using, as long as open switch (7).Very easy to use, the speed that generates gas can be controlled by by-pass cock (7).Three, interpolation or replacing reagent: the liquid reagent in the gas generator (4) uses the certain hour meeting thinning, needs replacing liquid.When changing liquid, open raffinate catheter switch (2), discharging of waste liquid is fallen, off switch (2) adds new reactant liquor again in knapsack (3) then.When needing replacing or adding solid reagent, close airway tube switch (7), liquid reactants is pushed back in the knapsack (3), clog knapsack (3) upper end or clamp threeway plastic flexible pipe (1) with a rubber stopper with clip, take off rubber stopper (8), just can change or add the solid reagent of gas generator (4).

According to aforesaid operations, can carry out chemical reaction by solid and liquid and prepare gas, as hydrogen, carbon dioxide and acetylene etc.
