Description

Waste liquid collecting device
Technical Field

Biological experiments are a means for helping researchers understand biology, and are mostly found in scientific research and teaching experiments of scientific research institutions and colleges, and researchers need to purposefully observe and study the phenomena of organism structures and life activities which are not easy to observe under general conditions by using certain instruments, materials and medicines under specific environmental conditions through a scientific method.
After completing the biological experiment, the researchers have obtained the experimental result and also obtained the experimental waste liquid at the same time, the experimental waste liquid is usually the mixed liquid of the waste liquid and the experimental liquid medicine that the clean instrument produced, and general operating personnel collects the waste liquid in waste liquid cup or some plastics, glass container, then pours into in the waste liquid bucket again. Aerosols may be generated during the dumping of waste fluids, which can pose a health threat to operators, especially asthmatics and other people with respiratory diseases, if the concentration of the aerosol is high enough or if the operators are in such an environment for a long time. Meanwhile, aerosol is diffused in a laboratory or falls on a laboratory table and equipment, so that the laboratory environment is polluted, and the cleaning burden of operators is increased. In addition, the waste liquid is inevitably splashed in the process of pouring, and the surrounding environment is polluted.
When the existing waste liquid collecting device is used, the filter cloth and the exhaust fan are usually cooperated to operate, and waste liquid byproducts, namely aerosol and splashed waste liquid drops, are generated in the waste liquid absorbing process under the action of wind power generated by the operation of the exhaust fan. However, since the filter cloth is usually directly exposed to the air and is fixed in position, the waste liquid by-product on the filter cloth may be scattered in the air again in a non-collected state to pollute the laboratory.
Simultaneously, along with the increase of waste liquid accessory substance adhesion volume on the filter cloth, the exhaust fan sees through the filter cloth and weakens the adsorption efficiency of waste liquid accessory substance, and this just makes the filter cloth can't effectively adsorb the waste liquid accessory substance that the in-process produced of empting, just so need change the filter cloth at this moment. At present, the filter cloth is mostly manually disassembled by an operator, and then a new filter cloth is replaced, so that the operation is more complicated, and the time and the labor are wasted.
