The implementation principle of the embodiment is as follows: when the staff uses the medium pressure dehydration appearance, at first with support column 2 vertical installation on base 1 and twist set nut 24 to with support column 2 and base 1 reciprocal anchorage, then the staff can adjust the whole length of support column 2, and twist the top and touch knob 26 and make the tip of top touch screw 25 top touch at the terminal surface of inserted bar 22, thereby with inserted bar 22 and sleeve pipe 21 reciprocal anchorage. The operator can now screw the air reservoir 4 onto the base 1 and connect the hose 43 to the air inlet 31 of the pressure reducing valve 3. Then the worker places the filter paper 8 on the filter screen 621 and fixes it by the magnetic ring 81, and then the worker can load the drilling fluid into the filter cartridge 61 and cover the filter cover 62 and the sealing cover 63 on the end of the filter cartridge 61 in turn, and then fix the sealing cover 63 with the filter cartridge 61 using the fixing assembly 64. Finally, the worker installs the filter cup 6 at the air outlet 32 of the pressure reducing valve 3 and uses the inflation pipe 5 to inflate the air storage cylinder 4, and the drilling fluid in the filter cup 6 flows out of the connecting pipe 645 and is collected in the measuring cylinder 7.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
