Three stirring rods 514 are arranged between two adjacent lower filter screens.
In operation, as shown in fig. 1 to 13, in an initial state, the water inlets 211 and the water outlets 212 of the upper and lower filter barrels 210 and 220 are in an all-open state, and the water outlets 213 of the upper and lower filter barrels 210 and 220 are in a closed state. The sewage to be filtered is introduced from the water inlets 211 of the upper filter tub 210 and the lower filter tub 220 at the same time.
In the upper filter tub 210, sewage enters from the water inlet 211 of the upper filter tub 210, flows downward along the upper filter tub 210, is filtered by the plurality of upper filter screens 310 and adsorbed by the plurality of adsorption media, and is discharged from the water outlet 212 of the upper filter tub 210. The sewage impurities filtered by the upper filter screen 310 are accumulated on the upper surface of the upper filter screen 310. In the lower filter tub 220, sewage enters from the water inlet 211 of the lower filter tub 220, flows upward along the lower filter tub 220, passes through the filtration of the plurality of lower filter screens and the adsorption of the plurality of adsorption media, and is discharged from the water outlet 212 of the lower filter tub 220. The sewage impurity filtered by the lower filter screen is accumulated on the lower surface of the lower filter screen.
After the upper and lower filters 310 and 310 filter the sewage for a preset time, the driving motor 610 is started, and the upper and lower motors 611 and 612 of the driving motor 610 are rotated synchronously. The upper motor 611 drives the upper driving disk 660 to rotate, thereby driving the upper driving ring 620 and the upper shielding pipe 680 to rotate. The lower motor 612 rotates the lower drive disk 670, which in turn rotates the lower drive ring 630 and the lower shield 690. When the driving surface 621 of the upper driving ring 620 contacts with one upper driving post 640, the upper driving ring 620 can drive the upper driving post 640 to rotate in the first direction through friction transmission, and at the same time, the driving surface 621 of the lower driving ring 630 contacts with the lower driving post corresponding to another filter vat, and the lower driving ring 630 can drive the lower driving post to rotate through friction transmission.
When the upper driving post 640 rotates, the first lever 511 and the second lever 512 of the upper adjustment shaft 510 are driven to rotate in a first direction. Since the first rod 511 of the upper adjustment shaft 510 is screwed with the upper coupling cylinder 214, the upper water inlet stopper 530 is driven to move downward when the first rod 511 of the upper adjustment shaft 510 rotates in the first direction, and at the same time, the first rod 511 of the upper adjustment shaft 510 drives the upper reset ring 720 to rotate. The upper coil spring 710 is caused to accumulate force as the upper return ring 720 rotates. When the second rod 512 of the upper adjusting shaft 510 rotates in the first direction, the upper sleeve 551 is driven to rotate synchronously, so that the overlapping area of the notch on the upper sleeve 551 and the upper filter vat 210 is gradually reduced. When the upper water inlet block 530 closes the water inlet 211 of the upper filter tub 210, the upper sleeve 551 also closes the water outlet 212 of the upper filter tub 210, and the notch of the upper shielding pipe 680 coincides with the water outlet 213 of the upper filter tub 210. When the second rod 512 of the upper adjusting shaft 510 rotates, the distance between two adjacent upper filter screens 310 is increased, so that the active space of the adsorption medium is increased, and meanwhile, the second rod 512 of the upper adjusting shaft 510 drives the stirring rod 514 to rotate around the upper adjusting shaft 510 between two adjacent upper filter screens 310, so that the stirring rod 514 stirs the adsorption medium. At this time, due to the closing of the water inlet 211 and the water outlet 212 of the upper filter tub 210 and the opening of the water outlet 213 of the upper filter tub 210, the sewage flows upward from the lower filter tub 220, and the water flow has a backflushing effect on the upper filter screen 310, thereby being able to clean impurities on the upper surface of the upper filter screen 310 and discharge the sewage generated by cleaning the upper filter screen 310 from the water outlet 213 of the upper filter tub 210. As the upper driving ring 620 rotates, the driving surface 621 of the upper driving ring 620 is out of contact with the upper driving post 640, and the upper coil spring 710 releases the elastic force to rotate the upper reset second direction, thereby rotating the first lever 511 and the second lever 512 of the upper adjustment shaft 510 in the second direction. The first lever 511 and the second lever 512 of the upper adjustment shaft 510 are rotated in the second direction to drive the upper water inlet stopper 530 and the upper sleeve 551 to return to the original positions, and simultaneously, as the upper driving ring 620 is rotated, the upper shielding pipe 680 closes the water outlet 213 of the upper filter cartridge 210, and the driving surface 621 of the upper driving ring 620 is in frictional contact with the upper driving post 640 corresponding to the other filter cartridge.
When the lower driving post rotates, the first lever 511 and the second lever 512 of the lower adjusting shaft 520 are driven to rotate in a first direction. Since the first lever 511 of the lower adjustment shaft 520 is screw-engaged with the lower connection cylinder 221, when the first lever 511 of the lower adjustment shaft 520 is rotated in the first direction, the lower water inlet stopper is driven to move upward, and at the same time, the first lever 511 of the lower adjustment shaft 520 drives the lower reset ring to rotate. When the lower reset ring rotates, the lower coil spring is enabled to store force. When the second rod 512 of the lower adjusting shaft 520 rotates in the first direction, the lower sleeve is driven to rotate synchronously, so that the overlapping area of the notch on the lower sleeve and the lower filter vat 220 becomes smaller gradually. When the lower water inlet stopper closes the water inlet 211 of the lower filter tub 220, the lower sleeve also closes the water outlet 212 of the lower filter tub 220, and simultaneously the notch of the lower shielding pipe 690 coincides with the water outlet 213 of the lower filter tub 220. When the second rod 512 of the lower adjusting shaft 520 rotates, the distance between two adjacent lower filter screens is increased, so that the active space of the adsorption medium is increased, and meanwhile, the second rod 512 of the lower adjusting shaft 520 drives the stirring rod 514 to rotate around the upper adjusting shaft 510 between two adjacent lower filter screens, so that the stirring rod 514 stirs the adsorption medium. At this time, due to the closing of the water inlet 211 and the water outlet 212 of the lower filter tub 220 and the opening of the water outlet 213 of the lower filter tub 220, the sewage flows downward from the upper filter tub 210, and the water flow has a backflushing effect on the lower filter screen, thereby being capable of cleaning impurities on the lower surface of the lower filter screen and discharging the sewage generated by cleaning the lower filter screen from the water outlet 213 of the lower filter tub 220. With the rotation of the lower driving ring 630, the driving surface 621 of the lower driving ring 630 is out of contact with the lower driving post, and the lower coil spring release spring drives the upper reset second direction to rotate, thereby driving the first lever 511 and the second lever 512 of the lower adjustment shaft 520 to rotate in the second direction. The first lever 511 and the second lever 512 of the lower adjustment shaft 520 are rotated in the second direction to drive the lower water inlet stopper and the lower sleeve to return to the original positions, and simultaneously, as the lower driving ring 630 is rotated, the lower shielding pipe 690 closes the water outlet 213 of the upper filter tub 210, and the driving surface 621 of the lower driving ring 630 is in frictional contact with the corresponding lower driving post of the other filter tub.
When the upper and lower driving rings 620 and 630 are rotated by 360 °, the washing of all the upper and lower filter barrels 210 and 220 is completed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
