The invention discloses an adjustable gas suction device for a laboratory. The adjustable gas suction device comprises an arc-shaped gas suction cover, a first connecting pipe and a second connectingpipe, wherein an opening in the bottom end of the arc-shaped gas suction cover faces downwards, one end of the first connecting pipe is communicated with the top end of the arc-shaped gas suction cover, the outer wall of the other end of the first connecting pipe is provided with an external thread, the inner wall of one end of the second connecting pipe is provided with an internal thread, one end of the second connecting pipe is in threaded connection with the end, with the external thread, of the first connecting pipe, and the other end of the second connecting pipe is connected with a gaspurifying device. Dust gas produced in experiments is sucked and collected through the arc-shaped gas suction cover and then filtered and absorbed through the gas purifying device and is then discharged, the concentration of dust in the laboratory is greatly reduced, and the air quality in the laboratory is improved.
Description
technical field [0001] The invention belongs to the technical field of laboratory equipment, and in particular relates to an adjustable inhalation device for a laboratory. Background technique [0002] A laboratory is a place where experiments are performed. The laboratory is the cradle of science, the base of scientific research, the source of scientific and technological development, and plays a very important role in the development of science and technology. Laboratories can be divided into three categories according to their affiliation: the first category is a laboratory affiliated to a university or managed by a university; the second category belongs to a national institution, and some even an international institution; the third category belongs directly to a university. In the industrial enterprise sector, it serves the development and research of industrial technology. Various experimental activities are required in the laboratory, and a large amount of dust is ...
