Description
Technical field
The utility model relates to chemical a kind of chemistry teaching demonstration kipp gas generator, comprise liquid bottles, reaction tube, medicine frame and blast pipe, it is cylindric that reaction tube is, outer wall is provided with screw thread, lower end is fixed in liquid bottles chamber on diapire through the screw on liquid bottles upper wall, in the external wall of upper portion of reaction tube, be fixed with blast pipe, medicine frame is slidably connected by piston rod and reaction tube inwall, and piston rod extends reaction tube.
Background technology
In current chemistry teaching, conventional " kipp gas generator " produces instrument as the gas of chemical experiment, it is mainly made up of spherical hopper, Pear-Shaped container and the wireway with glass piston, its weak point is: volume is large, complex structure, not portable, little, the medicine of the gas pressure waste producing is large, installs instruments, packs into reagent all cumbersome in the time of experiment.
Summary of the invention
The purpose of this utility model is to provide a kind of chemistry teaching demonstration kipp gas generator, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of chemistry teaching demonstration kipp gas generator, comprise liquid bottles, reaction tube, medicine frame and blast pipe, it is cylindric that reaction tube is, outer wall is provided with screw thread, lower end is fixed in liquid bottles chamber on diapire through the screw on liquid bottles upper wall, in the external wall of upper portion of reaction tube, be fixed with blast pipe, medicine frame is slidably connected by piston rod and reaction tube inwall, piston rod extends reaction tube, described medicine frame bottom is connected and pushes up plug, top plug and reaction tube sidewall close contact, described reaction tube is provided with inlet opening in the upper end of liquid bottles inside, reaction tube lower end is provided with fluid hole.
Preferably, piston rod part is provided with briquetting.
Preferably, reaction tube top is provided with sealing-plug, and piston rod is connected with medicine frame through sealing-plug.
Preferably, liquid bottles is provided with liquid feed valve.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, portably use conveniently, reagent picks and places easily, and under vacuum state, can reduce medicine and waste, and improved conventional efficient.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1 liquid bottles, 2 reaction tubes, 3 top plugs, 4 briquettings, 5 medicine frames, 6 piston rods, 7 inlet openings, 8 fluid holes, 9 blast pipes, 10 liquid feed valves, 11 sealing-plugs.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of chemistry teaching demonstration kipp gas generator, comprise liquid bottles 1, reaction tube 2, medicine frame 5 and blast pipe 9, reaction tube 2 is cylindric, outer wall is provided with screw thread, lower end is fixed in liquid bottles 1 chamber on diapire through the screw on liquid bottles 1 upper wall, in the external wall of upper portion of reaction tube 2, be fixed with blast pipe 9, medicine frame 5 is slidably connected by piston rod 6 and reaction tube 2 inwalls, piston rod 6 extends reaction tube 2, medicine frame 5 bottoms are connected and push up plug 3, top plug 3 and reaction tube 2 sidewall close contacts, reaction tube 2 is provided with inlet opening 7 in the upper end of liquid bottles 1 inside, reaction tube 2 lower ends are provided with fluid hole 8, piston rod 6 tops are provided with briquetting 4, reaction tube 2 tops are provided with sealing-plug (11), piston rod 6 is connected with medicine frame 5 through sealing-plug 11, liquid bottles 1 is provided with liquid feed valve 10.
Using method is as follows:
Reaction tube 2 is put into liquid bottles 1, in medicine frame 5, put into required medicine, medicine frame 5 is filled in to reaction tube 2, by tight blocking 11, open liquid feed valve 10, upwards pull piston rod 6, then pour liquid in liquid feed valve 10, will close steam vent 9 simultaneously; By briquetting 4, under the effect of pressure, liquid overflows from fluid hole 8 downwards, enter reaction tube 2 from inlet opening 7 and react with the medicine in medicine frame 5, produce gas, open blast pipe 9, Exhaust Gas, close blast pipe 9, upwards pull piston rod 6, under pressure, liquid is back to liquid product 1 from inlet opening 7, cessation reaction, can be pulled to inlet opening 7 by medicine frame 5 bottoms, ensures that liquid all refluxes.
This use is novel is all transparent.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
