Hair plate touches travel switch, and travel switch will issue feedback signal to electric cabinet 18, and electric cabinet 18 will issue stop signal to the
Level-one filter cylinder automatic blowdown valve 15 and driving device 1, first order filter cylinder automatic blowdown valve 15 close, while driving device 1 stop to
It works, first order filter cylinder sewage absorpting heat 5 backwashes first order filter cylinder 6 during entire soil pick-up.
After first order filter cylinder filters a period of time, when accumulation of foreign matter is more on 21 inner wall of second level filter cylinder, reaching the
After the differential pressure value that second level differential pressure transmitter 17 is set, by trigger signal feedback to electric cabinet 18, electric cabinet 18 will issue starting certainly
For cleaning control signal to second level filter cylinder automatic blowdown valve 23 and driving device 1, second level filter cylinder automatic blowdown valve 23 will be by closing
Closed state operation is opened, while driving device 1 will bring into operation, and second level filter cylinder sewage absorpting heat 19 starts to inhale in the process of running
Dirt, sewage will flow to dirt sucking tube 7 from second level filter cylinder sewage absorpting heat 19 through second level cylinder soil pick-up branch pipe 20, because of dirt sucking tube isolation board 4
Dirt sucking tube 7 is isolated into two independent chambers up and down, sewage will from dirt sucking tube separate cavities through second level filter cylinder blowdown chamber 22 and
Second level filter cylinder automatic blowdown valve 23 is discharged.After stroke switch triggering plate 2 touches upper stroke switch 25, dirt sucking tube 7 is in lead screw
Axis 26 is run down under acting on, and is run up after travel switch trigger board 2 touches lower stroke switch 24, travel switch trigger board
It moves downward, is repeated in until being touched when second level differential pressure transmitter 17 is lower than setting value after 2 operations to upper stroke switch 25
To travel switch, travel switch will issue feedback signal to electric cabinet 18, and electric cabinet 18 will issue stop signal to the second level and filter
Cylinder automatic blowdown valve 23 and driving device 1, second level filter cylinder automatic blowdown valve 23 is closed, while driving device 1 is stopped to work, whole
Second level filter cylinder sewage absorpting heat 19 backwashes second level filter cylinder 21 during a soil pick-up.
Technical solution cited by the present invention and embodiment and non-limiting, with technical solution cited by the present invention and
Embodiment is equivalent or effect same approach is all in the range of the present invention is protected.
