If it is directly discharged into the atmosphere without treatment, it will cause serious pollution to the environment. In order to solve this problem, people have developed various waste gas treatment technologies, among which the filter box is a commonly used waste gas treatment equipment, which adsorbs and filters the waste gas by filling it with filter materials such as activated carbon, dry chemical filter material, and biological filter material, so as to achieve the purpose of purifying the waste gas. In the existing technology, the filter material in the filter box is usually filled manually, that is, the worker loads the filter material into the filter box.

Secondly, a large amount of dust will be generated during the filling process, which will pollute the environment and also cause harm to the health of the filling workers. Long-term exposure to dust will cause workers to suffer from respiratory diseases, etc. Finally, since the filling process is intermittent, the fan needs to be frequently switched on and off, which will also affect the service life of the equipment, thereby reducing efficiency and increasing certain safety hazards.
