Description
Technical field
The instructional device structure of the instructional device of the utility model category chemical experiment, especially chlorine preparing and bleaching experiment
Technology.
Background technology
The instructional device of existing chlorine preparing and bleaching experiment, due to structure and vessel, the chlorine produced holds
Outside easily is leaked to, although the gas of experiment is few, but still the problem of in environmental protection be present.
The content of the invention
The purpose of this utility model is precisely in order to overcome chlorine preparing in above-mentioned existing teaching experiment to be imparted knowledge to students with bleaching experiment
The defects of device is present and a kind of very environmentally friendly, simple in construction, easily operated, lively chlorine preparing easily grasped and bleaching are provided
The instructional device of experiment.
The purpose of this utility model is achieved by the following technical solution.
A kind of instructional device produced with bleaching experiment of " environment-friendly type " chlorine, it is characterised in that including a clear vial
The big wide-mouth bottle of formula structure and three small test tubes being located at side by side in big wide-mouth bottle, two are respectively adopted between three small test tubes and is led
Pipe sequentially connects, and the outlet of wherein conduit is located at big wide-mouth bottle bottom；Big wide-mouth bottle is using the large rubber plug sealing with jack, lab scale
The small plug sealing with jack is respectively adopted in pipe；Boiling tube is inserted with large rubber plug and using the Boiling tube plug envelope with jack
Mouthful, it is inserted with separatory funnel and T-shaped conduit respectively on Boiling tube plug；One side of T-shaped conduit is inserted through Boiling tube plug,
The other end imports or export gas, and the lower end of T-shaped conduit is inserted in large rubber plug and stretched into by small plug in small test tube.
The beneficial effects of the utility model are that producing and floating for chlorine is more intuitively understood and grasped quite convenient for learner
The relevant knowledge tested in vain, the presentation process of teaching demonstration device and its environmental protection, and vividly, it is perceptual, easy to operate, demonstration dress
The color change of color and red cloth simple in construction, that be easy to observe chlorine is put, is very suitable for classroom instruction.
Brief description of the drawings
Fig. 1 is the device for making schematic diagram of former chlorine；
Fig. 2 is the utility model structure diagram.
Embodiment
See Fig. 2, a kind of instructional device produced with bleaching experiment of " environment-friendly type " chlorine, including a transparent vial-type structure

Not Cai Yong two conduits 11A, 11B, 11C sequentially connect, wherein conduit 11C outlet is located at the big bottom of wide-mouth bottle 4；Big wide-mouth bottle
4 are sealed using the large rubber plug 8 with jack, and small plug 9A, 9B, 9C sealing with jack is respectively adopted in small test tube；On large rubber plug 8
It is inserted with Boiling tube 1 and is sealed using the Boiling tube plug 10 with jack, is inserted with separatory funnel 7 respectively on Boiling tube plug 10
With T-shaped conduit 2；One side of T-shaped conduit 2 is inserted through Boiling tube plug 10, and the other end imports or export gas, T-shaped conduit 2
Lower end be inserted in large rubber plug 8 and stretched into by small plug 9A in small test tube 3A.
Boiling tube 1 is used to contain potassium permanganate；Special T-shaped conduit 2 is used to importing and exporting gas；Small test tube 3A is used to do
Dry chlorine；Small test tube 3B and 3C are used to examine the Bleachability of chlorine；Big wide-mouth bottle 4 is used to prevent the collection of tail gas and prevents chlorine
Air pollution etc.；Separatory funnel 7 is used to contain concentrated hydrochloric acid.
Separatory funnel 7 is equipped with potassium permanganate equipped with concentrated hydrochloric acid and special T-shaped conduit 2 by large rubber plug 10 and Boiling tube 1
It is connected；The piston 2A connections gas bottle of the special left end of T-shaped conduit 2 collects chlorine or carries out chlorine others relevant nature reality
Test；And the lower end piston 2B of T-shaped conduit 2 glass tubes that are connected through large rubber plug 8 and by sebific duct with small test tube 3A stretch to lab scale
At pipe 3A bottom 1/5；Small plug 9A two sockets on small test tube 3A, the socket on the left side is used to insert grass tube 11A, right
The socket on side is used to insert grass tube 11B by dry chlorine importing equipped with the small test tube 3B for drying cloth；On small test tube 3B
Small plug 9B also has two sockets, and the socket on the left side is used to insert grass tube 9B, and the socket on the right is used to plug in conduit 9C by drying
Chlorine import equipped with moistening cloth small test tube 3C in；Two sockets on the small plugs of small test tube 3C, the socket on the left side are used for
Conduit 3C is inserted, the socket on the right is molten for inserting sodium hydroxide that its opening of conduit 9C contains the big wide-mouth bottle of remaining chlorine importing
In liquid.
