Description
Technical field
The utility model is related to a kind of chemical experiment apparatus, specifically a kind of heating frame of high school chemical experiment.
Background technology
Chemistry is one kind of natural science, and composition, property, structure and the change of material are studied on molecule, atom level
Rule；Create the science of novel substance.The world is chemical then be the mankind to recognize and transform the main of the material world by material composition
One of ways and means.It is a subject with a long history and dynamic, and its achievement is the important mark of social civilization
Two kinds of versions of chemical change and physical change are there are in will, chemistry.
Chemistry is a natural science based on experiment, and carrying out experiment can not only be such that the rudimentary knowledge of student more pricks
It is real, it can more effectively improve students ' thinking ability and practical competence.In chemical experiment, its experiment appliance can help student
More effectively more easily doing experiment carrys out learning chemistry for progress, but there are many defects in use, and it is in chemical experiment
The middle heating frame that uses of heating liquid, it is fixed can not to adjust height so that be clamped in test tube bottom on heating frame with
The distance of the flame of alcolhol burner can not be adjusted, and its general knowledge is both known about in the outer fireworks, internal flame, flame core of flare, its outer fireworks
Temperature highest, in experiment, the low flare for causing alcolhol burner of test tube wraps up whole test tube bottom so that test tube bottom is in wine
The internal flame or flame core of smart lights flame, which not only reduces the efficiency of heating surface, also extend the heat time, add experimental period,
Conventional efficient is reduced, when actually being tested, often needs the direct holding test tubes of experimenter to be placed on the outer of alcolhol burner flame
Tested on fireworks, it easily causes the liquid of heating to scald experimenter, or causes experimenter's arm to be ached, and arm occurs
Shake, easily causes danger；In addition, entering factory in an experiment needs to shake test tube so that the chemical substance added in test tube is shaken
It is even, prevent from being heated on flame while shaking, and traditional heating frame can only grip test tube and be heated, nothing
Method shakes test tube, and typically experimenter rocks and heated while being placed on flame top manually, is unfavorable for student's operation, easily because of behaviour
Make improper or error and occur unexpected injury, the operation for being unfavorable for teachers and students' safety carries out chemical experiment；In chemical test, stone
It for heating liquid is the wire netting on the heating frame on alcolhol burner that web, which is, and it is to clip an asbestos by two panels wire netting
That is dried after water immersion is chintzy, is a kind of conventional chemical apparatuses, but its asbestos fibre can cause between asbestosis, pleura
The diseases such as rind gall, many country selections, which are completely forbidden, uses this dangerous substances, and some other country examines asbestos closely
Danger, therefore, Chinese junior-senior high school chemical laboratory appoint uses asbestos gauge, its to teachers and students it is healthy cause seriously endanger,
Seriously it is unfavorable for the healthy of teachers and students, it is inconvenient for use.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of heating frame of high school chemical experiment, solve chemical real
In testing, because the distance between the flame of alcolhol burner that uses and beaker bottom are that fixation can not be adjusted, so as to need artificial
Raise test tube or change small size alcolhol burner to adjust distance, it causes operator's arm to ache, and its distance keeps difficult shadow
The problem of ringing quality of experiments；Its used asbestos gauge is solved because easily causing the diseases such as asbestosis, mesothelioma of pleura, and it is right
The problem of teachers and students' health is damaged；Solve when heating liquid, because the test tube clamp that its tradition is used is fixed, it is impossible to
It is even to swing, it is necessary to need the artificial test tube that shakes to be heated in experiment, easily cause student and scalded in experimental implementation
