Abstract
The utility model relates to an iron wire is combustion experiment demonstration ware in oxygen, including the system oxygen unit: gas bottle (2) bottleneck stopper has diplopore rubber buffer (3), and long neck funnel (4) are inserted in (3) holes of diplopore rubber buffer, and glass return bend (5) are inserted in another hole, its characterized in that: glass return bend A (5) connects another glass return bend B (8) through rubber tube (6), and glass return bend B (8) inserts the rubber buffer of plastic bottle of the no end (7) bottleneck, and plastic bottle (7) bottleneck of the no end is fixed down on iron stand platform (1). Because have oxygen continually to make the iron wire burning very violent, mars no. 4 is penetrated, emits big calorimetry, at the bottom of burning back black melts constantly splashes down bottle, and duration is very long.
Description
Technical field
The utility model belongs to chemistry subject teaching aid, is specifically related to a kind of iron wire combustion experiment demonstration device in oxygen.
Background technology
During the science and education version ninth grade chemistry character of 3.1 oxygen and purposes one save, iron wire is combustion experiment in oxygen, due to the not enough iron wire of amount of oxygen do not burn or combustion phenomena not obvious; Careless iron wire touching gas bottle bottle wall can make gas bottle burst in addition, can affect class efficacy like this.
Summary of the invention
The purpose of this utility model is the defect in order to overcome prior art, provides a kind of iron wire combustion experiment demonstration device in oxygen, thus efficiently solves problems of the prior art.
The technical scheme taked for realizing the purpose of this utility model is: a kind of iron wire is combustion experiment demonstration device in oxygen, comprise oxygen device of air: gas bottle (2) bottleneck is plugged with double-hole rubber plug (3), long neck funnel (4) is inserted in double-hole rubber plug (3) holes, and glass bend pipe (5) is inserted in another hole; It is characterized in that: glass bend pipe A(5) connect another glass bend pipe B (8) by rubber tube (6), glass bend pipe B (8) inserts the rubber plug of bottomless plastic bottle (7) bottleneck, and bottomless plastic bottle (7) bottleneck is fixed on iron stand (1) down.
Glass bend pipe B (8) stretches into the bend pipe end cover one joint rubber tube of bottomless plastic bottle (7), and glass bend pipe plays a part to cushion oxygen, and cover rubber tube is in case the fused mass after iron wire burning splashes to glass bend pipe and makes it burst.
The beneficial effects of the utility model are:
1. very violent owing to there being oxygen endlessly to make iron wire burn, Mars four is penetrated, and releases large calorimetric, and at the bottom of after burning, black fused mass constantly splashes down bottle, and the duration is very long.
2. observation of students phenomenon is very clear, improves the interest of Students ' Learning chemistry.
3. replace gas bottle to test with plastic bottle, save experiment spending to school; Turn waste into wealth, protection of the environment; Training student is apt to use the consciousness that discarded object is at one's side tested, made scientific researches simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
1-iron stand, 2-gas bottle, 3-double-hole rubber plug, 4-long neck funnel, 5-glass bend pipe A, 6-rubber tube, the bottomless plastic bottle of 7-, 8-glass bend pipe B.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1, is shown in Fig. 1, and a kind of iron wire is combustion experiment demonstration device in oxygen, comprises oxygen device of air: gas bottle 2 bottleneck is plugged with double-hole rubber plug 3, and long neck funnel 4 is inserted in double-hole rubber plug 3 one holes, and glass bend pipe 5 is inserted in another hole; It is characterized in that: glass bend pipe A5 connects another glass bend pipe B8 by rubber tube 6, glass bend pipe B8 inserts the rubber plug of bottomless plastic bottle 7 bottleneck, and bottomless plastic bottle 7 bottleneck is fixed on iron stand 1 down.
Glass bend pipe B8 stretches into the bend pipe end cover one joint rubber tube of bottomless plastic bottle 7, and glass bend pipe plays a part to cushion oxygen, and cover rubber tube is in case the fused mass after iron wire burning splashes to glass bend pipe and makes it burst.
Using method:
1. 500 milliliters of plastic bottles are intercepted bottom and stand upside down and be fixed on iron stand, then oxygen device of air and plastics spout are coupled together.
2. use upwards air-discharging method to collect in plastic bottle by the oxygen of generation, collect completely with the batten inspection oxygen of band Mars after a while, the matchstick of spiral fashion iron wire one end is burnt, extend into during after-flame in plastic bottle to matchstick.
3. iron wire burning is very violent, and Mars four is penetrated, and releases large calorimetric, and at the bottom of after burning, black fused mass constantly splashes down bottle, and the experimental phenomena duration is very long.
Claims (2)
1. iron wire combustion experiment demonstration device in oxygen, comprises oxygen device of air: gas bottle (2) bottleneck is plugged with double-hole rubber plug (3), and long neck funnel (4) is inserted in double-hole rubber plug (3) holes, and glass bend pipe (5) is inserted in another hole; It is characterized in that: glass bend pipe A(5) connect another glass bend pipe B (8) by rubber tube (6), glass bend pipe B (8) inserts the rubber plug of bottomless plastic bottle (7) bottleneck, and bottomless plastic bottle (7) bottleneck is fixed on iron stand (1) down.
2. iron wire combustion experiment demonstration device in oxygen as claimed in claim 1, is characterized in that: glass bend pipe B (8) stretches into the bend pipe end cover one joint rubber tube of bottomless plastic bottle (7).
