Abstract
The utility model discloses a kind of burning condition demonstration instrument, comprise container a, the opening part of container a puts into stopper, stopper has a through hole, through straight tube in the through hole on stopper, straight tube stretch into be positioned over container a inside bottom container b in, the top of container b arranges pallet, straight tube is through pallet, and one end that straight tube is positioned at container a outside is connected with one end of rubber tube, and the other end of rubber tube connects inflatable ball.The utility model can demonstrate multiple combustion reaction simultaneously, and the utility model structure is simple, and easy for installation, use safety, demonstrating effect is obvious.
Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to a kind of burning condition demonstration instrument.
Background technology
Substance combustion, except itself is combustible, also needs by other external condition, and teacher, when lecturing on chemistry to student, is difficult to vivo allow student understand and grasp this knowledge point near theory explaination.Existing classroom combustion experiment instrument often function singleness, can only demonstrate a certain combustion reaction, student can not be allowed simultaneously intuitively to arrive multiple combustion reaction, grasp multiple knowledge point.
Utility model content
The purpose of this utility model is to provide a kind of burning condition demonstration instrument, solves the problem that existing combustion appliance can not demonstrate multiple combustion reaction simultaneously.
The technical scheme that the utility model adopts is: a kind of burning condition demonstration instrument, comprise container a, the opening part of container a puts into stopper, stopper has a through hole, through straight tube in the through hole on stopper, straight tube stretch into be positioned over container a inside bottom container b in, the top of container b arranges pallet, straight tube is through pallet, and one end that straight tube is positioned at container a outside is connected with one end of rubber tube, and the other end of rubber tube connects inflatable ball.
Feature of the present utility model is also: stopper has second through hole, and this through hole is connected with bend pipe, and the inside of container a is led in one end of bend pipe, and one end that bend pipe is positioned at container a outside is connected with getter bag.
The upper surface of pallet arranges dividing plate.
The beneficial effects of the utility model are: a kind of burning condition demonstration instrument of the utility model, by arranging container b and straight tube in container a, and pallet is set above container b, multiple combustion reaction can be demonstrated simultaneously, the utility model structure is simple, easy for installation, use safety, demonstrating effect is obvious.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of burning condition demonstration instrument of the utility model.
In figure, 1. container a, 2. stopper, 3. straight tube, 4. rubber tube, 5. inflatable ball, 6. container b, 7. pallet, 8. baffle plate, 9. bend pipe, 10. getter bag.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
A kind of burning condition demonstration instrument of the utility model, as shown in Figure 1, comprise container a1, the opening part of container a1 puts into stopper 2, stopper 2 has two through holes, straight tube 3 is set in container a1, straight tube 3 is through a through hole on stopper 2, the inside bottom placing container b6 of container a1, straight tube 3 stretches into the inside of container b6, and the top of container b6 arranges pallet 7, and straight tube 3 is through pallet 7, one end that straight tube 3 is positioned at container a1 outside is connected with one end of rubber tube 4, and the other end of rubber tube 4 connects inflatable ball 5.Another through hole on stopper 2 is connected with bend pipe 9, and the inside of container a1 is led in one end of bend pipe 9, and one end that bend pipe 9 is positioned at container a1 outside is connected with getter bag 10.The upper surface of pallet 7 arranges dividing plate 8.
When demonstrating the burning condition of white phosphorus and red phosphorus, in container b6, put into white phosphorus, then in container b6, inject distilled water, ensure that the liquid level of distilled water is positioned at the top of straight tube 3 lower end, then dividing plate 8 both sides on pallet 7 place white phosphorus and red phosphorus respectively.
First heat to container a1 with alcohol heater or other thermal source, when temperature rises to certain value, the white phosphorus be positioned on pallet 7 can be observed and first blaze up, and red phosphorus does not burn; After continuing heating a period of time again, red phosphorus just takes fire.This illustrates that temperature must reach the burning-point of material, and burning just can occur, and illustrates that the burning-point of red phosphorus is higher than the burning-point of white phosphorus.
In whole heating process, the white phosphorus being arranged in container b6 distilled water does not burn all the time, and pinching inflatable ball 5 is given in container b6 by rubber tube 4 and straight tube 3 and passed into air, after a period of time, can see that the white phosphorus in container b6 takes fire, this illustrates that burning needs could occur by oxygen.
Discarding that burning produces is entered in getter bag 10 by bend pipe 9, avoids waste pollution environment.
