Room is filtered by vacuum, filtrate through output end and lower contact on the next interface and its internal pipeline enter vacuum filtration tank,
And the circulation line of next stage is flowed into, since vacuum filtration pump is necessarily dependent upon air circulation, therefore the vacuum filtration process is only right
Vacant independent filter chamber works, and does not have an impact to the independent filter chamber in using, and after the completion of suction filtration, closes vacuum filtration
Pump；
Independent filter chamber after the completion of switching should replace its internal filter layer, unscrew the top cover first, release top
The limitation to filter core is covered, then extracts filter core out, the intracorporal filter cotton filtering layer of the inner casing is taken out, then unscrews the outer housing, take
Then the intracorporal hollow-fibre membrane filter layer of the shell out is placed in new hollow-fibre membrane filter layer, then will replace filter layer
Outer housing afterwards screws on the inner housing outer wall, and new filter cotton filtering layer is finally placed in inner housing, completes to filter core
Replacement；The filter core more finished changing is inserted into original filtering tank groove, then installs and screw top cover, fix filter core, thus complete
The resetting of pairs of independent filter chamber waits until that switching uses next time；
And in the design of the inner housing and outer housing, if being offered on the inner housing described first and shell body sidewall
Dry filter hole, bottom is closed (U-tube structure), to guarantee that filtered fluid is only filtered out from the side wall of shell, will not be gathered in
The bottom of shell uses filter core more uniform, and service life and filter efficiency are higher；Secondly the filter core is that hanging setting exists
In the groove of the filtering tank, therefore drain sky is formd between the filter hole of the filter core and the drainage hole of the bottom portion of groove
Between and channel, keep filtrate flows smooth.
The advantage of the invention is that：The present invention realizes filtering using the design of recoverable filtering tank and its auxiliary equipment
Medium is switched fast, and does not influence recycling for mixed solution, is had excellent practical value, is effectively improved damping
The re-usability energy and service efficiency of liquid.

After the completion of suction filtration, vacuum filtration pump 8 is closed；
Independent filter chamber 36 after the completion of switching should replace its internal filter layer, unscrew the top cover 362 first, solve
Limitation except top cover 362 to filter core 361, then extract filter core 361 out, the filter cotton filtering layer 373 in the inner housing 37 is taken out, then
The outer housing 38 is unscrewed, the hollow-fibre membrane filter layer 382 in the outer housing 38 is taken out, is then placed in new doughnut
Film filter layer, then the outer housing 38 after replacement filter layer is screwed on 37 outer wall of inner housing, finally set in inner housing 37
Enter new filter cotton filtering layer, completes the replacement to filter core 361；The filter core 361 more finished changing is inserted into original filtering tank groove 333
In, then top cover 362 is installed and screws, keep filter core 361 fixed, to complete the resetting to independent filter chamber 36, waits until next time
Switching uses；
And in the design of the inner housing 37 and outer housing 38, on the inner housing 37 described first and 38 side wall of outer housing
Several filter hole 39 are offered, bottom is closed (U-tube structure), to guarantee that filtered fluid is only filtered out from the side wall of shell,
It will not be gathered in the bottom of shell, use filter core more uniform, service life and filter efficiency are higher；Secondly the filter core
