Chemical element analysis device

Abstract

The invention relates to the technical field of experimental teaching, in particular to a chemical element analysis device. The chemical element analysis device includes a demonstration platform. Theupper end face of the demonstration platform is fixedly connected with a demonstration box. The left end face of the demonstration box is fixedly connected with a fixing plate. The right side of the fixing plate is fixedly connected with a fixing ring. A baffle is arranged on the right side of the fixing ring. The left end face of the baffle is fixedly connected with a rubber layer. The right endface of the fixing plate is fixedly connected with a spring. The inner side of the right end face of the demonstration box is fixedly connected with an exhaust fan. The bottom end of the exhaust fan is communicated with an exhaust pipe. The other end of the exhaust pipe is fixedly connected with a gas collecting bottle. Through the fixing plate, the baffle, the exhaust fan and the gas collecting bottle, harmful gas produced during experiment can be collected and handled. Thus, the human health will not be harmed, and the environment will not be polluted. The design is novel and scientific. Thechemical element analysis device has great economic benefit and a wide market prospect, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of experimental teaching, in particular to a chemical element analysis device. Background technique [0002] At present, when conducting chemistry teaching in schools, on-site chemical demonstration experiments are one of the necessary teaching contents, but in chemical demonstration experiments, many experiments will produce smoke or harmful poisonous gases, and the experiments are required to be carried out in a fume hood. Large-scale instruments such as fume hoods are not equipped in many school laboratories. Even if they are equipped, they cannot be brought to the classroom for demonstration experiments. For experiments that produce smoke and harmful and toxic gases, teachers can only carry out experiments without any protective measures , which not only affects the effect of teaching, but also causes great harm to the health of teachers and students. Therefore, the demand for a chemical element analysis...

[0002] At present, when carrying out chemistry teaching in schools, on-site chemical demonstration experiments are one of the necessary teaching contents, but in chemical demonstration experiments, many experiments will produce smoke or harmful and toxic gases, and the experiments are required to be carried out in a fume hood. Large-scale instruments such as fume hoods are not equipped in many school laboratories. Even if they are equipped, they cannot be brought to the classroom for demonstration experiments. For experiments that produce smoke and harmful and toxic gases, teachers can only carry out experiments without any protective measures. , which not only affects the effect of teaching, but also causes great harm to the health of teachers and students. Therefore, the demand for a chemical element analysis device is increasing day by day

[0003] Most of the demonstration devices for chemical elements currently on the market are fixed and non-adjustable, which will make some students who are far away cannot see the effect of the experiment and affect the effect of teaching; Safe design leads to some safety hazards in the experiment process; there are also some element demonstration devices used in chemical experiments, which do not filter and collect harmful gases that may be generated in the experiment, which not only endangers people's health, but also pollutes the environment. environment, etc. Therefore, a chemical element analysis device is proposed to address the above problems
