Abstract

The invention discloses experimental teaching equipment with a gas exchange function. The experimental teaching equipment comprises an equipment main body, wherein a corrosion-resistant top plate is arranged at the upper end of the equipment main body; a heat-insulating plate is arranged on the corrosion-resistant top plate; an object placing disk and a water tank are arranged at the two ends of the heat-insulating plate respectively; a tap is arranged on the side face of the water tank; a gas exchange device is arranged at the upper end of the corrosion-resistant top plate; an object collection cabinet, a chemical storage cabinet and a waste water collecting chamber are arranged at the lower end of the equipment main body; the object collection cabinet comprises a pulling cabinet; a test tube frame, hooks and a collecting tank are arranged inside the pulling cabinet; the chemical storage cabinet comprises sealed pulling cabinets and a refrigeration box; the waste water collecting chamber comprises an opening and closing door; a cavity is arranged in the equipment main body inside the opening and closing door; a wastewater collecting tank is arranged inside the cavity; the equipment main body is provided with corrosion-resistant transparent glass plates; the upper ends of the corrosion-resistant transparent glass plates are movably connected with the equipment main body through rotating shafts; the corrosion-resistant transparent glass plates are provided with buckles. The experimental teaching equipment is comprehensive in function, convenient and safe to use, and good in gas exchange effect.

Description

Technical field [0001] The invention relates to a teaching equipment, belonging to the field of teaching equipment, and more specifically to an experimental teaching equipment with a ventilation function. Background technique [0002] In junior and senior high school teaching, in physics, biology, especially chemistry teaching, there are often many experimental courses, such as the physics oil film method to estimate molecular size experiments, biological chromosome experiments, chlorophyll extraction experiments, and various oxidations in chemistry. Reduction experiments, etc., all require a large number of experimental instruments, equipment, raw materials and experimental sites. Normal school teachers are limited, and many do not have a complete set of experimental equipment. Most of them are simple tools and equipment, which not only have poor experimental results. The teaching effect is not as it should be, and the safety is poor, which can easily cause harm to students, and...

Problems solved by technology

[0002] In the teaching of junior and senior high schools, in the teaching of physics, biology, especially chemistry, there are often many experimental courses, such as the physical oil film method to estimate the molecular size experiment, biological chromosome experiment, chlorophyll extraction experiment, various chemical oxidation Reduction experiments, etc., all of which require a large number of experimental instruments, equipment, raw materials and experimental sites. The general school teachers are limited, and many of them do not have a complete set of experimental equipment. Most of them are simple tools and equipment. Not only the experimental effect is poor, Can not get the proper teaching effect, and the safety is poor, it is easy to cause harm to the students, bringing a lot of inconvenience and safety hazards to the school, teachers and students

[0003] In chemical experiments, such as some experiments such as hydrogen reduction with acid, metal replacement reaction, etc., due to the inaccuracy of the amount or heat during the experiment, the students can easily cause the reaction to be too dramatic, so that it is ejected from the test tube, and the replaced hydrogen is also produced. If it cannot be discharged normally, it is very easy to cause harm to nearby students. At the same time, when the teacher is doing the experiment, the students usually gather around the experimental table to watch, and the students are crowded. harm
