Safe and environment-friendly type chemical experiment table

Abstract

The invention discloses a safe and environment-friendly type chemical experiment table. The safe and environment-friendly type chemical experiment table comprises a table top, wherein an opening is formed in the middle part of the table top; a sealing plate is mounted at the upper side of the opening; an experiment cavity is formed in the lower side of the opening; the experiment cavity is weldedwith the lower side of a support plate; a connecting cylinder is arranged at the outer side of the experiment cavity; a connecting cavity is formed in the outer side of the lower end of the connectingcylinder; the lower end of the experiment cavity is connected with a connecting cover through a sealed bearing; a filter screen is arranged inside the connecting cover; a connecting pipe is arrangedat the lower side of the connecting cover; the right side of the connecting pipe is connected with a connecting bent pipe; a gas suction pump is mounted on the connecting bent pipe; an air purifier isarranged at the right side of the connecting bent pipe; a liquid storage cavity is formed in the lower side of the connecting pipe; a U-shaped connecting frame is arranged at the outer side of the liquid storage cavity; the upper side of the U-shaped connecting frame is fixedly welded with the lower side of the connecting cavity; and support bases are fixedly welded with four corners of the lowerside of the U-shaped connecting frame. The safe and environment-friendly type chemical experiment table can effectively perform chemical experiments on equipment, so that the safety performance during chemical experiments can be effectively ensured.

Description

technical field

[0001] The invention relates to the field of chemistry, in particular to a safe and environment-friendly chemical experiment bench. Background technique

[0002] The word "chemistry", if only interpreted literally, is "the science of change". Chemistry, like physics, is a basic science of natural science. Chemistry is a natural science based on experiments. The periodic table of chemical elements proposed by Mendeleev greatly promoted the development of chemistry. Nowadays, many people call chemistry "central science", because chemistry is the core of some scientific disciplines, such as material science, nanotechnology, biochemistry, etc. Chemistry is a natural science that studies the composition, structure, properties, and changes of substances at the atomic level, which is also the core basis of chemical changes. There are five secondary disciplines under modern chemistry: inorganic chemistry, organic chemistry, physical chemistry, analytical chemistr...
