Compared with the prior art, the multipurpose gas generator has the following characteristics: (1) saving the quantity of gas preparation equipment in a laboratory, and realizing the task of the preparation of middle and primary school conventional gases such as H2, CO2, H2S, O2 and the like with one set of device by changing devices for containing different solid drugs; (2) being economic and environment-friendly: flexibly changing the liquid medicines within 25-75ml according the needed gas amount without being filling up the container, and being capable of repeatedly using MnO2 catalyst; (3) having humanized design: being convenient for cleaning, easy for carrying and simple in operation; and (4) being beneficial for promotion: having common manufacturing materials and simple and convenient method and being beneficial to production in teaching instrument manufacturers and acceptance in laboratories of the middle and primary schools.
Description
(1) technical field: the utility model relates to the chemical experiment device that a kind of middle and primary schools chemistry, biology laboratory conventional gas prepare usefulness, specifically is to can be used for preparing H
2, CO
2, H
2S, O
2The gas generator of using etc. the usefulness of multiple gases more.
(2) prior art: middle and primary schools' the most frequently used gas preparation facilities in laboratory is a kipp gas generator at present, but there is following point in practice in this device:
1,1. the medicine requirement is big, and each reaction needs liquid drug is filled with container, causes waste.
2. prepare the gas type limitation, can make H
2, CO
2, H
2Gases such as S, but can't produce another kind of conventional gas O in the biochemical experiment of middle and primary schools
2Reaction medicine limitation can only be liquid and the solid particle system gas that reacts.
3. using has gas leak phenomenon midway, is difficult to stop immediately getting rid of.
4. type is an overall structure, and complex structure carries inconvenience, with after can't dismantle, it is difficult to clean.
2, in " the compulsory education curricular standard experiment textbook ninth grade chemistry first volume ", quoted a with H
2O
2Be reactant, MnO
2Produce the easy device of oxygen as catalyst.This method is with Powdered MnO
2Directly be invested in H
2O
2Conical flask in react.Its adverse consequences is the catalyst MnO that can recycle
2After experiment finishes, go out of use and (will reclaim MnO
2Need to filter earlier, the back is dry, and complex operation is lost more than gain).Except the significant wastage that causes medicine, discarded MnO
2Also environment is caused certain pollution.
(3) summary of the invention: the purpose of this utility model just provides a kind of simple in structure, and convenient disassembly can prepare H
2, CO
2, H
2S, O
2The gas generator of using etc. multiple gases more.
The utility model is used gas generator more, comprises long neck funnel, wide-mouth bottle and bottle stopper, and the funnel neck tube inserts in the wide-mouth bottle by bottle stopper, inserts a conduit on the described bottle stopper, and conduit is provided with switch; Be provided with a solid medicine storing apparatus in described wide-mouth bottle bottom.
Described medicine storing apparatus is a barrel, has the test solution ostium around the barrel.
The hole of inserting for the funnel neck tube is arranged at described barrel bottom, is with a pad on the neck tube outside stretching out the hole.
Described pad is an apron.

2Powder.
There is the hole of inserting for the funnel neck tube at described plates middle part, is with a pad on the neck tube outside stretching out the hole.
Described pad is an apron.
The utility model compared with prior art has following characteristics: 1. save laboratory gas preparation equipment quantity, by using different solid medicine storing apparatus instead, realized that a covering device can prepare H
2, CO
2, H
2S, O
2Task Deng middle and primary schools' conventional gas.
2. economical environment-protective: liquid drug can need not to fill with container according to gas requirement change flexibly between 25-75ml; And MnO
2The repeated use of catalyst then has and saves and the double effects of environmental protection.
3. humanization designing: it is convenient to clean, and is easy to carry about with one, simple to operate.
4. be beneficial to popularization: it is common to make material, and method is easy, is beneficial to production of instruments used for education producer and middle and primary schools laboratory and adopts.
5. enlarge reaction medicine scope, can be used for liquid and solid particle or powdered reaction system gas.
Design principle of the present utility model is, open the long neck funnel cock after, liquid reactant is entered in the wide-mouth bottle by funnel under the gravity effect, liquid, solid reactant contact, reaction beginning; Switch on the closure catheter for closing, the gas access denial of going out in the bottle, air pressure increases, and to funnel, solid-state liquid reactant is isolated with the reactant liquor back-pressure in the wide-mouth bottle, and reaction stops.
MnO
2Serve as catalyst in oxygen making reaction, its quality and chemical property all do not change before and after reaction, and be reusable.
The utility model using method is as follows:
A, with solid (containing particle, powder) and liquid reactions system gas: the medicine storing apparatus that solid particle or powder will be housed places in the wide-mouth bottle; The closure catheter for closing switch, the jam-pack rubber stopper adds the liquid medicine in the 25-75ml scope in funnel, open switch, begins reaction; Close switch, reaction stops.
B, system oxygen: will be stained with MnO
2The medicine storing apparatus of powder is displaced the medicine storing apparatus in the A step, adds 25-75ml H in funnel
2O
2, open switch, begin reaction; Close switch, reaction stops.
