The heating saving type chemical reaction gas generating device is characterized in that a lower half ball-shaped part of an original Kipps apparatus calabash-shaped container is removed, an upper opening of an upper half ball-shaped part is expanded, a neck portion is thickened and lengthened, and the double-opening circular-bottom special-shaped flask (3) is formed. A tetrafluoroethylene partition piece (4) is sleeved at the bottom end of the ball-shaped funnel (1). A circular hole is formed in the middle of the tetrafluoroethylene partition piece (4). The diameter of the tetrafluoroethylene partition piece (4) is slightly smaller than that of an upper opening of the special-shaped flask (3). The tetrafluoroethylene partition piece (4) is inserted into 1/5 of the bottom of the special-shaped flask (3). The periphery of the tetrafluoroethylene partition piece (4) is enabled to be connected with the inner wall of the special-shaped flask (3). The upper opening of the special-shaped flask (3) is connected with the ball-shaped funnel (1) in an abrasive mode. The problems that during an experiment process, an existing Kipps apparatus used in a laboratory is too large in liquid medicine using amount and can not be heated are solved.
Description
One, technical field
The utility model relates to a kind of chemical experimental instrument, particularly kipp gas generator.
Two, background technology
In middle school chemistry experiment teaching, the kipp gas generator that generally uses mainly is made of spherical hopper, calabash shaped reaction vessel and wireway.Wherein spherical hopper is placed in the top mouth of calabash shaped container, and wireway is located at spheroid place, calabash shaped container top, limited air valve or clip on wireway.The reaction platform is the cucurbit neck place at narrow place in the centre of calabash shaped container, and this reaction platform is approximately gone to the bottom as relying on calabash shaped container top spherical container, there is no special reaction platform.This kipp gas generator causes the required aqueous chemical drug dosage of reaction excessive because the following spherical part volume of calabash shaped reaction vessel is very large, causes the chemicals waste, and can not add thermal response.
For the problems referred to above, utility model " improved Kipp generator ", CN200720087234.X, Sun Xishan proposes to fix the elliptical vessel of a bottom lock in second spherical part cavity of kipp gas generator calabash shaped container.But this scheme can only solve required aqueous chemical drug dosage problems of too, can not solve the chemical reaction heating problems, and processing difficulties; Utility model " improved Kipp generator " and for example, CN200920280418.7, Zhang Yanjun, his scheme is chemical reaction to be placed in the test tube bottom of lateral opening hole.He has solved aqueous chemical drug dosage problems of too, but can not react heating.Also have " Miniature chemical experimental instrument for middle school " CN92214244.0, Song Guangzhi and utility model " gas generator ", CN94227308.7, but clear letter.Their thinking is all chemical reaction to be placed in the bottom of bottom opening test tube.This scheme can be saved the aqueous chemical drug dosage, can react heating again.But the reative cell space is too small, there is no the gas buffer space, and when the gas vent valve closing, gasification system is in the totally-enclosed state, and the remaining liquid of reative cell still produces gas, and closed system air pressure is raise.If misoperation makes the remaining liquid of reative cell produce gas flow excessive, may blast.
Three, summary of the invention
The purpose of this utility model is not affect under the prerequisite of experiment effect, designs a kind of aqueous chemical drug dosage less, and can add smoothly the gas generation device of thermal response.
The technical scheme that the utility model adopts is: second spherical part of original kipp gas generator calabash shaped container is removed, the expansion suitable for reading of first spherical part, the neck overstriking extends, make twoport round bottom abnormity flask into, the spherical hopper bottom puts the diameter of an Intermediate Gray circular hole than special-shaped flask smaller tetrafluoroethene partition suitable for reading, insert special-shaped drag approximately 1/5th places, tetrafluoroethene partition periphery is joined with special-shaped flask inwall; Suitable for reading and the funnel frosted of abnormity flask is connected.
The utlity model has following advantage and beneficial effect: the utility model can make the reaction liquid amount of medicament greatly reduce, and can also heat the acceleration chemical reaction, and simple in structure, easy to manufacture.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Five, the specific embodiment
As shown in Figure 1, second spherical part of original kipp gas generator calabash shaped container is removed, the expansion suitable for reading of first spherical part, the neck overstriking extends, make twoport round bottom abnormity flask 3 into, spherical hopper 1 bottom puts the diameter of an Intermediate Gray circular hole than special-shaped flask smaller tetrafluoroethene partition 4 suitable for reading, inserts approximately 1/5th places, special-shaped flask 3 bottoms, and tetrafluoroethene partition 4 peripheries are joined with special-shaped flask 3 inwalls; Suitable for reading and the spherical hopper frosted of abnormity flask 3 is connected.
Air-tightness that should first testing fixture before using, method be, as shown in Figure 1 device is placed on common electric jacket, with the instrument folder, special-shaped flask 3 is fixed on iron stand.Open cock 6, add water in spherical hopper 1, when water level cut-out tap 6 during near tetrafluoroethene partition 4, continue to add water, make waterborne being raised in spherical hopper 1.In standing a moment, observe spherical hopper 1 water surface and whether descend, as the explanation gas leakage that descends.Air-leak section may be the ground place that air guide pipe close 5, the cock 6 on wireway or the spherical hopper of gas outlet on special-shaped flask 3 contacts with special-shaped flask 3.Should be coated with at the ground place skim vaseline as gas leakage.
During initial the use, special-shaped flask 3 is placed on common electric jacket, spherical hopper 1 bottom puts the diameter of an Intermediate Gray circular hole than special-shaped flask smaller tetrafluoroethene partition 4 suitable for reading, inserts approximately 1/5th places, special-shaped flask 3 bottoms, and tetrafluoroethene partition 4 peripheries are joined with special-shaped flask 3 inwalls; Suitable for reading and the spherical hopper frosted of abnormity flask 3 is connected.Above-mentioned special-shaped flask 3 and spherical hopper 1 are tilted together, solid drugs particle (as: zinc granule) is added by inserting air guide pipe close 5 side mouths on special-shaped flask 3, then put positive instrument, with the instrument folder, special-shaped flask 3 is fixed on iron stand.Again air guide pipe close 5 is filled in.Then add liquid drug (as: watery hydrochloric acid) by 1 mouthful of spherical hopper.During use, turn on wireway cock 6, liquid drug (as: watery hydrochloric acid) is flow to the bottom of special-shaped flask 3 by spherical hopper 1, then contacts and react with solid drugs particle (as: zinc granule) in the middle part of rising to, and the gas of generation is emitted from wireway.The used time is not closed the cock 6 of wireway, and the gas that the interior continuation reaction of special-shaped flask 3 produces makes pressure increasing in container, and liquid drug is pushed back spherical hopper 1, and liquid drug and solid drugs particle are disengaged, and reaction stops voluntarily.Use the utility model preparing gas very convenient, can in time control the generation of reaction or stop, can also be by the heating accelerated reaction.
