The utility model discloses a further improvement is provided with the valve on inlet and the liquid outlet, and the valve is used for controlling the speed that flows in and flow out.

The utility model discloses a further improvement still is provided with two observation windows that are used for observing the inside solution situation of change of barrel on the barrel wall, sets for preceding observation window and back observation window, can adopt to inlay the toughened glass realization on the barrel wall, and preceding observation window's effect is that the observation solution liquid level comes to adjust air outlet means, makes solution fill whole barrel, and back observation window's effect is that the observation has strained the solution liquid level and judges the filter core jam condition, clears up and change the filter core.

The utility model discloses a further improvement still includes the push rod, and the push rod setting can adopt the welded mode to realize on the upper portion outer wall of barrel, and the push rod makes things convenient for the workman to remove this filter still further.

The utility model has the advantages that: the utility model can complete the purpose of removing impurities and filtering the solution when the unit operates normally under the state of not completely discharging the solution, and has simple structure, flexible movement and repeated use; the circulating pump can be linked to independently filter the barreled solution, so that the flexibility is strong; and the movable floor is convenient to move and use in different workshops.
