Anti-splashing device for microporous filtering membrane

The utility model provides an anti-splashing device for a microporous filtration membrane, which belongs to the technical field of microporous filtration, and is characterized in that when the anti-splashing device is used, liquid needing to be filtered is poured into a cylinder shell through a funnel, then a second ball valve and a first ball valve are closed, and after a lifting pump is opened, the liquid is pumped into the cylinder shell under the huge pumping force of the lifting pump; liquid firstly passes through the filter shell to intercept large-particle impurities and then passes through the filter membrane cylinder to be subjected to micro-filtration, so that liquid filtration is achieved, the negative pressure degree in the cylinder shell can be observed through the pressure gauge, work is stopped when the negative pressure lower limit is reached, the splashing phenomenon is avoided in the process, and the environment and people are well protected; when the interior of the cylinder shell is flushe
