AI Technical Summary
When existing cloth funnels are used to transfer compounds to other containers for further processing after filtration, there are issues such as sealing failure and human error, which can cause the compounds to come into contact with air, leading to spontaneous combustion or other safety risks.
Design a safe cloth funnel with an upper and lower connection between the support section and the connecting section, and equipped with a protective component. The protective component can seal the opening of the support section and introduce inert gas or quenching reagent to form an inert environment and prevent the compound from contacting the external oxygen. At the same time, the negative pressure generated by the suction filtration component accelerates filtration. Combined with the transparent material, it is easy to observe and control the reaction process.
It ensures the integrity and safety of the filtration process, prevents compounds from spontaneously combusting or oxidizing, reduces safety hazards during transfer, improves filtration efficiency and operational safety, and is suitable for chemical reactions that are prone to spontaneous combustion or are sensitive to oxygen.
