Description
Technical field
The utility model relates to a kind of experimental demonstration device, especially a kind of device of amplifying observation chemical reaction.
Background technology
Chemistry is a natural science based on experiment.Especially in the primary stage of chemistry teaching, various lecture experiment is often inseparable with teaching.Due to the restriction of teaching environment in the teaching of more existing junior-senior high schools, a lot of experiment is usually carried out in classroom.When the operating process of reality, although these lecture experiment general process are comparatively simple, also there are some danger, the experimental phenomena such as emitted light and heat, or produce the virose product of some tools.
Although commercially also sell some experiment protective covers existing, these experiment protective covers generally all have stronger professional, and cost is higher, and adopts hard-wired mode, is difficult to mobile, and is not suitable for the lecture experiment of primary chemical.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to use, easy dismounting, is convenient to mobile, the device of a kind of amplifying observation chemical reaction of exhaust gas recycling.
The utility model is achieved through the following technical solutions:
A kind of device of amplifying observation chemical reaction, it is characterized in that: comprise a cover body, described cover body adopts transparent material, the front end face of this cover body is embedded with convex lens, this cover body rear end face is shaped with two handle holes, described cover body upper surface setting-in one gland bonnet, this cover body lower surface is movably installed with multiple base, and described cover body side is shaped with the exhaust apparatus and device for recovering tail gas that are connected with cover body inside.
And described cover body is a cube, is all shaped with mounting hole in the corner, lower surface of this cover body, in described mounting hole, is all set with base.
And the described handle hole position be positioned at outside cover body is shaped with a circle bulge loop.
And described exhaust apparatus is a Simple inflatable pump, the inflation inlet of this Simple inflatable pump is connected with described cover body inside.
And described device for recovering tail gas is a Drexel bottle being communicated with Ethylene recov, and described Drexel bottle is connected with described cover body inside.
Advantage of the present utility model and good effect are:
In the utility model, cover body adopts transparent material to coordinate the convex lens of front end face setting-in to be conducive to the demonstration of testing, and avoids producing the dead angle can't see; The handle hole that cover body rear end face is made, facilitates the operation of experimenter in experimentation to use; To adding experimental provision in cover body and testing the clean of rear cover body inside before the convenient experiment of gland bonnet of cover body upper surface setting-in; The base that the activity of cover body bottom surface is installed, is convenient to cover body carrying with fixing; The Simple inflatable pump that cover body side is made coordinates the Drexel bottle being communicated with Ethylene recov, the waste gas produced can be reclaimed, thus avoid the pollution to classroom environment in experimentation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial sectional view of enclosure portion in Fig. 1.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of device of amplifying observation chemical reaction, the utility model innovation is, comprise a cover body 2, described cover body adopts transparent material, the front end face of this cover body is embedded with convex lens 3, and this cover body rear end face is shaped with two handle holes 5, described cover body upper surface setting-in one gland bonnet 4, this cover body lower surface is movably installed with multiple base 9, and described cover body side is shaped with the exhaust apparatus and device for recovering tail gas that are connected with cover body inside.Described exhaust apparatus is a Simple inflatable pump 1, and the inflation inlet of this Simple inflatable pump is connected with described cover body inside by draft tube 10.Described device for recovering tail gas is a Drexel bottle 8 being communicated with Ethylene recov 7, and described Drexel bottle is connected with described cover body inside by escape pipe 6.
In the present embodiment, the conveniently movement of cover body and fixing, described cover body is a cube, is all shaped with mounting hole 13 in the corner, lower surface of this cover body, and described mounting hole is all sleeved on limited post 12 outer rim of making base upper end.
In the present embodiment, the described handle hole position be positioned at outside cover body is shaped with a circle bulge loop 11, and this bulge loop outer rim can be used for the end of oppositely suit operation gloves, operation gloves can be stretched into cover body inside along handle hole afterwards.
Use procedure of the present utility model is:
When the utility model uses, the mounting hole contraposition that cover body lower surface is made after first being lifted by cover body by experimenter is sleeved on outside the limited post made in base, open gland bonnet afterwards, by experiment reagent, the equipment such as instrument are steadily positioned in cover body, gland bonnet can be inlaid in cover body upper surface, gland bonnet can be inlaid in cover body upper surface, and sealing rubber strip or sponge strip are installed in the surface crimped mutually with cover body.
If described experiment can produce waste gas, experimenter only again cover body need be connected Simple inflatable pump respectively and Drexel bottle can be tested, after experiment terminates, user only need press Simple inflatable pump and make to produce air-flow in cover body, waste gas is entered Drexel bottle to carry out absorbing the waste gas recovery process that can complete experiment, the tool equipment of experiment is carried out storage by last opening encapsulation lid can complete whole experimentation.
In the utility model, cover body adopts transparent material to coordinate the convex lens of front end face setting-in to be conducive to the demonstration of testing, and avoids the dead angle can't see; The handle hole that cover body rear end face is made, facilitates the operation of experimenter in experimentation to use; To adding experimental provision in cover body and testing the clean of rear cover body inside before the convenient experiment of gland bonnet of cover body upper surface setting-in; The base that the activity of cover body bottom surface is installed, is convenient to cover body carrying with fixing; The Simple inflatable pump that cover body side is made coordinates the Drexel bottle being communicated with Ethylene recov, the waste gas produced can be reclaimed, thus avoid the pollution to classroom environment in experimentation.
