Description

Technical Field

[0001] The utility model relates to the technical field of test benches, in particular to a central test bench for chemistry laboratories which is convenient for collecting waste liquid. Background Art

[0002] A test bench is provided in a chemical laboratory, and the test bench is used for conducting chemical experiments. In the process of conducting chemical experiments, waste liquid is sometimes generated. If the waste liquid is directly poured into a cleaning bench and then washed away with tap water, it is easy to cause water pollution. Because harmful substances are easily present in the waste liquid generated by chemical experiments, a waste liquid collection barrel is generally provided in the laboratory to collect the waste liquid generated by chemical experiments, and then the waste liquid is centrally treated. However, the waste liquid dumping place of the test bench is currently open, so when the test bench is used, the odor generated by the waste liquid is easy to affect human health, and it is not convenient to classify and dump. Therefore, in order to correct the above-mentioned defects, we propose a central test bench for chemical laboratories that is convenient for collecting waste liquid. Utility Model Content
