Abstract
The utility model provides a gas generating device for a chemical teaching experiment. The gas generating device for the chemical teaching experiment is characterized by comprising a gas generator with a cross section of oval shaped transparent materials, the lower portion of the gas generator is arranged in a balance weight bottom seat with an oval positioning groove, the gas generator is a composite sandwich structure, a water inlet and a water outlet is arranged in an inner cavity of an interlayer, ring-shaped scale lines are arranged on the side wall of the gas generator, the ring-shaped scale lines encircle a whole gas generator, a plug cover which is matched with the gas generator is arranged above the gas generating device, a liquid injecting pipe is fixed on the plug cover, the lower end of the liquid pipe is arranged close to the bottom of the gas generator, the upper end of the liquid injecting pipe is fixed on the plug cover, a gas discharging pipe is also fixed on the plug cover, an adjusting valve is arranged on the gas discharging pipe, a fixing groove is arranged on the plug cover, and a liquid injection hopper is arranged in the fixing groove in matching mode. The gas generating device for the chemical teaching experiment has the advantages of being capable of preventing from toppling over, rotating and moving, and adjustable in temperature.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, especially a kind of chemistry experiment gas generating unit.
Background technology
When carrying out chemical experiment in middle school or the senior secondary course, generally all can use the chemistry experiment gas generating unit, but, at present the chemistry experiment that generally adopts of institute only is an independent gas generator with in the gas generating unit, because of carelessness gas generator is knocked over easily when testing or movement, and some gas reaction, can cause that small vibration is arranged, easy like this its inner reactant that causes is poured down or forth, and easily health is damaged.In addition, existing chemistry experiment can not be regulated temperature with gas generating unit self experimental concrete the needs, and reaction medium spills with the gas generating unit mouth from chemistry experiment easily in the experimentation, easily teachers and students is damaged; A side of gas generator is provided with scale in addition, can not satisfy the student and observe read untrue from a plurality of visual angles.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and a kind of overturning-preventing, rotation and movement is provided, and the adjustable chemistry experiment gas generating unit of temperature.
This programme is achieved by the following technical measures: a kind of chemistry experiment gas generating unit, comprise that the cross section is the gas generator of oval transparent material, the bottom of described gas generator is seated in the counter weight base with oval detent, gas generator is composite sandwich structural, the interlayer inner chamber is with intake-outlet, be provided with the circular scale line on the described gas generator sidewall, described graduation mark is around whole gas generator, there is the gag that is mated the gas generator top, be fixed with the liquid injection pipe that the lower end is positioned at close gas generator bottom on the described gag, the upper end of described liquid injection pipe is fixed on the gag, also be fixed with blast pipe on the described gag, be provided with control valve on the described blast pipe, be provided with holddown groove on the described gag, cooperate in the described holddown groove filling funnel is installed.
Concrete characteristics of the present utility model also have, and also are provided with handle on the aforesaid gas generator sidewall.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this chemistry experiment is with in the gas generating unit, the bottom of gas generator is installed in the counter weight base with oval detent, by oval detent gas generator is firmly located, cause its inner reaction medium to pour down or forth in case because of carelessness chemistry experiment is knocked over, rotates with gas generating unit or move in the experimentation; Gas generator is the composite sandwich structural interlayer, the interlayer inner chamber is with intake-outlet, can be filled with cooling and heat medium at the interlayer inner chamber, the gas generator inboard is provided with thermometer, can add in the interlayer according to concrete experiment needs and fill heating or cooling medium, observe chemistry experiment with the temperature in the gas generating unit by thermometer simultaneously; Be provided with the circular scale line on the gas generator sidewall, described graduation mark makes things convenient for teachers and students to carry out the observation capacity from all angles around whole gas generator like this.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
