Abstract

The utility model discloses a device for demonstrating incomplete combustion. The device comprises a fire-resistant cylinder (1) with two ends opened; one end of the fire-resistant cylinder (1) is provided with a gate (2) movably connected with the fire-resistant cylinder (1) and capable of blocking the end part; and when the gate blocks one end of the fire-resistant cylinder, air can be prevented from entering the fire-resistant cylinder from the blocked end. By adopting the structure, when at use, a combustible material is placed inside the fire-resistant cylinder, the combustible material is ignited and the gate is closed, the combustible material is incompletely arranged inside the fire-resistant cylinder, dark smoke can be ignited and part of the dark smoke can be deposited and left on a smoke hood according to different arrangement, and thus, incomplete combustion can be well demonstrated to students.

Description

One is used for demonstrating unburnt device
Technical field
The utility model relates to a kind of for demonstrating unburnt device.
Background technology
Rough burning is a kind of important chemical change, occurs when rough burning, and the thermal value of failing to emit due to fuel all discharges, and has not only caused the waste of fuel but also pollutes the environment.In teaching process, in order to demonstrate rough burning phenomenon to student, in prior art, usually adopt candle under anaerobic environment, burn produce black smoke demonstrate rough burning phenomenon, in the black smoke that burning produces, there is combustible therefore can burn away due to also surplus, but in prior art, be difficult to the black smoke that ignition combustion directly perceived produces, student cannot get information about unburnt phenomenon.
Utility model content
The purpose of this utility model is to solve in prior art to be difficult to the black smoke that ignition combustion directly perceived produces, and student cannot get information about the problem of unburnt phenomenon.
The technical solution adopted in the utility model is: one is used for demonstrating unburnt device, comprise the fire-resistant cylindrical shell of both ends open, one end of fire-resistant cylindrical shell is provided with gate that be flexibly connected with fire-resistant cylindrical shell and can this end end of shutoff, in the time of one end of the fire-resistant cylindrical shell of gate shutoff, can stop air from being entered in fire-resistant cylindrical shell by shutoff end.
As further improvement of the utility model, the bore that fire-resistant cylindrical shell is provided with one end of gate is greater than the bore of the fire-resistant cylindrical shell other end, the slideway that fire-resistant cylinder body bottom is provided with and gate size is suitable, and gate end face is positioned at slideway and gate can move along slideway.
As further improvement of the utility model, fire-resistant cylindrical shell bore is fixed with petticoat pipe on less one end, between petticoat pipe and fire-resistant cylindrical shell end, has certain spacing.
As further improvement of the utility model, fire-resistant cylinder inboard wall is fixed with can be for the combustible apparatus for placing of circulation of air.
As further improvement of the utility model, combustible apparatus for placing is entanglement.
As further improvement of the utility model, described fire-resistant cylindrical shell is transparent fire-resistant cylindrical shell.
As further improvement of the utility model, described transparent fire-resistant cylindrical shell is glass cylindrical shell.
As further improvement of the utility model, described fire-resistant cylinder body outer wall is connected with handle.
The beneficial effects of the utility model are: adopted after this structure, when use, combustible is placed in fire-resistant cylindrical shell, after combustible is lighted by closing gate, combustible not exclusively arranges in fire-resistant cylindrical shell, according to different settings, both can light black smoke, and also can allow a part of black smoke deposition remain on petticoat pipe, thereby can be good at demonstrating rough burning phenomenon to student.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the schematic diagram of gate in the utility model.
Shown in figure: 1 fire-resistant cylindrical shell, 2 gates, 3 petticoat pipes, 4 entanglement, 5 handles.
Embodiment
Below in conjunction with Fig. 1,2, the utility model is described further.
As shown in Figure 1, 2, one is used for demonstrating unburnt device, comprise the fire-resistant cylindrical shell 1 of both ends open, one end of fire-resistant cylindrical shell 1 is provided with gate 2 that be flexibly connected with fire-resistant cylindrical shell 1 and can this end end of shutoff, in the time of one end of the fire-resistant cylindrical shell of gate shutoff, can stop air from being entered in fire-resistant cylindrical shell by shutoff end, the bore of one end that is provided with gate of described fire-resistant cylindrical shell 1 is greater than the bore of the fire-resistant cylindrical shell other end, fire-resistant cylinder body bottom is provided with the slideway suitable with gate size, and gate end face is positioned at slideway and gate can move along slideway.Described fire-resistant cylindrical shell 1 bore is fixed with petticoat pipe 3 on less one end, between petticoat pipe and fire-resistant cylindrical shell 1 end, there is certain spacing, described fire-resistant cylindrical shell 1 inwall is fixed with can be for the combustible apparatus for placing of circulation of air, described combustible apparatus for placing is entanglement 4, described fire-resistant cylindrical shell 1 is glass cylindrical shell, and described fire-resistant cylindrical shell 1 outer wall is connected with handle 5.
The utility model has adopted after this structure, when use, combustible is placed in fire-resistant cylindrical shell 1 and (for example, after paper being rolled into the shape suitable with fire-resistant cylindrical shell 1, is placed on fire-resistant cylindrical shell 1, or candle is placed in fire-resistant cylindrical shell 1), after combustible is lighted, gate 2 is closed, after fire-resistant cylindrical shell 1 is emerged flue gas, put burning fume and just can demonstrate combustion thing rough burning.In order to guarantee combustible rough burning, the bore of one end that is provided with gate of described fire-resistant cylindrical shell 1 is greater than the bore of the fire-resistant cylindrical shell other end.In order to make student can observe intuitively the black smoke that rough burning produces, described fire-resistant cylindrical shell 1 bore is fixed with petticoat pipe 3 on less one end, between petticoat pipe and fire-resistant cylindrical shell 1 end, have certain spacing, the black smoke that rough burning produces is like this understood some deposition and is remained on petticoat pipe 3.In order can conveniently to demonstrate, described fire-resistant cylindrical shell 1 inwall is fixed with can be for the combustible apparatus for placing of circulation of air, and described combustible apparatus for placing is entanglement 4, lights after combustible being placed on when use on entanglement 4.Fire-resistant inner barrel situation while burning for student can be seen, described fire-resistant cylindrical shell 1 is glass cylindrical shell.In order to be convenient for carrying or convenient carrying out of demonstrating, described fire-resistant cylindrical shell 1 outer wall is connected with handle 5, when use, can fire-resistant cylindrical shell 1 be picked up by holding handle 5, is easy to carry.Can be by hand held demonstration of fire-resistant cylindrical shell 1 when demonstration, also fire-resistant cylindrical shell 1 can be placed in the plane to (for example, on desk or dais) demonstrates, be placed on screen is also to adopt following method to demonstrate: before demonstration, the gate of just fire-resistant cylindrical shell 1 is opened, combustible is placed and in the plane and after lighting fire-resistant cylindrical shell 1 is enclosed within outside combustible, thereby can demonstrate easily.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; can also on the basis of above-described embodiment, carry out various permutation and combination and conversion; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model is carried out all drop in protection domain of the present utility model.
