Description

Waste liquid collecting device

Technical Field

The invention relates to the technical field of experiments, in particular to a waste liquid collecting device.

Background

The experiments are classified into simulation experiments, control experiments, ideal experiments, and observation experiments, wherein the observation experiments are used in biology. Biological experiments are means for helping researchers understand biology, and are mostly found in scientific research and teaching experiments of scientific research institutions and higher institutions, and researchers need to apply certain instruments, materials and medicines under specific environmental conditions, and purposely observe biological structures and vital activity phenomena which are not easy to observe under the general conditions of research through a scientific method.

After the biological experiment is completed, researchers obtain experimental results and experimental waste liquid, wherein the experimental waste liquid is usually a mixed liquid of waste liquid generated by a cleaning instrument and experimental liquid medicine, and general operators collect the waste liquid in a waste liquid cup or a plurality of plastic and glass containers and then pour the waste liquid into a waste liquid barrel. Aerosol may be generated during pouring of the waste liquid, if the concentration of aerosol is high enough or the operator is in such an environment for a long time, this may pose a threat to the health of the operator, especially for asthmatic patients and other people with respiratory diseases. At the same time, aerosols are scattered in the laboratory or fall on laboratory tables and equipment, which not only pollute the laboratory environment, but also increase the cleaning burden on the operators. In addition, the waste liquid is unavoidably 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 used in a matched mode, and waste liquid byproducts, namely aerosol and splashed waste liquid drops, are generated in the process of adsorbing the waste liquid by utilizing the wind force generated by the operation of the exhaust fan. However, since the filter cloth is usually directly exposed to air and is fixed in position, the waste liquid by-product on the filter cloth may fly again in the air in a non-collecting state, contaminating the laboratory.

Meanwhile, as the adhesion amount of the waste liquid byproducts on the filter cloth is increased, the adsorption capacity of the exhaust fan to the waste liquid byproducts through the filter cloth is weakened, so that the filter cloth cannot effectively adsorb the waste liquid byproducts generated in the dumping process, and the filter cloth needs to be replaced at this time. At present, an operator manually removes the filter cloth and replaces the filter cloth with a new filter cloth, so that the operation is complex, and time and labor are wasted.
