Teacher demonstration platform for chemistry laboratory

Abstract

The invention discloses a teacher demonstration platform for a chemistry laboratory and relates to the field of laboratory equipment. The demonstration platform comprises a base, a demonstration platform main body, a supporting plate, an exhaust plate, a water purifying tank and a sewage tank, wherein a concentric-square-shaped groove is formed in the edge of the top face of the demonstration platform main body, the exhaust plate is rotatably arranged on the outer edge of the top face of the supporting plate, and a plurality of illuminants and inhaling hoods are arranged on the front face; and a water tank, a water outlet pipe and a control panel are arranged on the top of the water purifying tank. The concentric-square-shaped groove is formed in the demonstration platform main body, that is, the concentric-square-shaped groove collects and guides residual flowing water on the experimental table board to a waste water tank, so that the environment polluting degree is reduced; by rotatably arranging the exhaust device and the illuminants on the top of the supporting plate, the teacher demonstration platform is flexible to use and high in practicality; and as the exhaust hoods on the exhaust plate are equivalent to the experimental table board in size, the exhaust effect is excellent. The functions of controllable water yield and controllable water outlet temperature are partially achieved by arranging the water purifying tank, so that various water using demands in the chemistry laboratory are met.

Description

technical field [0001] The invention relates to the field of laboratory equipment, in particular to a demonstration table for teachers in a chemical laboratory. Background technique [0002] The teacher's demonstration table in the chemistry laboratory is a kind of experimental equipment that is convenient for teachers to describe chemical experiments. When doing chemical experiments, the teacher must demonstrate according to a set of strict and cumbersome operating procedures. Once the chemical reagents are dumped, the chemical reagents will flow along the table to the cabinet or the experimental instruments in the cabinet to corrode and pollute the environment at the same time; and when doing chemical experiments , it is necessary to weaken the irritating smell emitted by chemical reagents, ventilation and air extraction equipment is essential, if there is no ventilation function, chemicals are easy to pollute and the smell is irritating to teachers and students, but the e...
