The present invention is specifically described with reference to the accompanying drawing, as shown in figures 1 to 6.
In the present embodiment, step 1: primary filtration, the sewage generated in production process is discharged to by water inlet pipe 28
It in water tank 2, precipitates sewage tentatively wherein, the liquid level signal in water tank 2 is detected by liquid level sensor 3, and will
Signal is sent in controller 27, after liquid level reaches a certain level, is controlled by controller 27 and is opened electrically operated valve 8, make sewage
Entered in circular filter case by protective net 6, water outlet 5, connection water pipe 7, electrically operated valve 8, water inlet 9, in the process, first
Impurity in sewage is carried out to be deposited to 2 bottom of water tank, then biggish impurity is intercepted by protective net 6, is prevented
These biggish impurity result in blockage to this device, influence working efficiency；
Step 2: backwash, with the progress of filtering, has some impurity to result in blockage it, by flow on the inside of protective net 6
Counter 34 carries out the detection of water velocity, and sends signal in controller 27, when the one of water velocity therein reduction
It after determining degree, is controlled by controller 27 and closes electrically operated valve 8, start suction pump 29, by suction pump 29 by the water of the top of water tank 2
It is extracted into connection water pipe 7, and the impurity of 6 inside of protective net is washed open, in the process, detected by flowmeter counter 34,
And dredged by suction pump 29, it has ensured water speed out, has improved filter efficiency；
Third step；Rotation filtering, into the water in circular filter case 1 by circular table exhalant canal 11, Vertical Channel 14,
Curved catheter 16 falls on above circular ring type filter screen 25 and is filtered, and after filtering a period of time herein, starts servo motor 21
Rotation drives curved catheter 16 to rotate, and outlet pipe 24 is rotated by connecting rod 22, connecting shaft 23, replaces strain position,
The spherical ball 19 of 17 lower section of support rod rotates in ring groove 20, plays a supporting role to curved catheter 16, in this process
In, drive outlet pipe 24 to replace position by servo motor 21, the position different to annulus filter screen 25 is filtered, extends
Its service life, and the position of outlet pipe 24 can be determined by servo motor 21, square aperture is turned in outlet pipe 24
When at 37, electrically operated valve 8 is closed, stops filtering；
Step 4: cleaning impurity drives outlet pipe 24 to rotate after impurity is accumulated to a certain extent by servo motor 21,
And the flexible brush 42 of lateral 41 lower section of fixed link is rotated, the impurity of 25 upper surface of annulus filter screen is swept into rectangular open
It at mouthful, and makes it into accommodating box 40, is detected by pressure sensor 44, and send signal in controller 27, when
After impurity in accommodating box 40 reaches constant weight, by the control of controller 27 starting, warning lamp 47 is lighted, loudspeaker 48 sounds, and is mentioned
Awake staff clears up, and staff opens electromagnetic lock 51, pulls open rotation gear door 50, accommodating box 40 is taken out, carry out clear
Accommodating box 40 after cleaning out, is put back to original position by reason, is closed rotation gear door 50, is locked electromagnetic lock 51, is completed entire worked
Journey is rotated by flexible brush 42 during place and clears up impurity, ensured filter efficiency.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
