The utility model discloses a novel defoaming and vacuumizing device in a transparent
soil material preparation process, which comprises a
barrel body, a sealing cover, a deflation valve, a stop valve, a pressure gauge, a vacuum connecting tee joint, a vacuum meter and a
vacuum pump, handles are mounted on two sides of the
barrel body, and a pressure automatic sealing cover is mounted at the top of the
barrel body. The left end and the right end of the vacuum connecting tee joint are connected with the
vacuum pressure gauge and the vacuum degree meter through bolts respectively, the middle of the vacuum connecting tee joint is connected with the stop valve and the
vacuum pump through the connecting
pipe and the clamping piece, the
oil mist filter screens are installed at the discharging end of the
vacuum pump, the two
layers of
oil mist filter screens are arranged at intervals, and the
oil mist filter screens are installed and connected through bolts. The utility model provides a novel defoaming and vacuumizing device in a transparent
soil material preparation process, which solves the problems that an existing oil seal type vacuum pump cannot defoam under stable pressure when being used for preparing a transparent
soil material, and oil mist is discharged due to
backflow of oil steam when the vacuum pump works; oil and gas can be brought into the vacuum barrel due to oil and gas carrying or
decomposition and the like to cause
oil pollution to the transparent
soil test piece.
