A plurality of connecting arms 330 horizontally arranged are arranged on the pillar 300 along the circumferential direction, a vertically arranged connecting rod 340 is arranged at the tail end of each connecting arm 330, the upper end of each connecting rod 340 is connected with the corresponding connecting arm 330, and a filter disc 400 is arranged at the lower end of each connecting rod 340.

The filter disc 400 is provided with a plurality of filter holes 410, the size and shape of the filter disc 400 are the same as those of the interior of the wastewater tank 100, and the filter disc 400 is slidably coupled to the inner wall of the wastewater tank 100, and the filter disc 400 can slide up and down in the wastewater tank 100. The inside of connecting rod 340 is cavity, still is equipped with second motor 350 on connecting arm 330, and the output shaft of second motor 350 is connected with pivot 360 downwards, and pivot 360 passes connecting arm 330, connecting rod 340 and filter disc 400, and the bottom of pivot 360 is equipped with detachable filter screen 500.

The filter screen 500 is tightly attached to the bottom surface of the filter disc 400, the filter screen 500 comprises a steel ring 510 and a thin wire 520, the steel ring 510 comprises two steel rings 510 which are one big and one small, and the thin wire 520 is woven between the two steel rings 510 and tightened to form the filter screen. The large steel ring 510 is the same as the filter disc 400 in size, and the small steel ring 510 is used for connecting with the rotating shaft 360, so that the filter screen covers the whole filter disc 400, in this embodiment, the small steel ring 510 is clamped with the bottom of the rotating shaft 360.

The filter screen woven by the thin wires 520 comprises a plurality of dense rings 530, the shape and the size of the dense rings 530 are the same as those of the filter holes 410, and the number and the arrangement mode of the dense rings 530 are also the same as those of the filter holes. The portion of the screen outside the dense circles 530 is comprised of a very small number of thin threads 520. As shown in fig. 2, a small amount of thread 520 can be placed under the filter holes 410 when the dense circles 530 are offset from the filter holes 410.

After sewage is poured into the sewage cylinder 100, the first motor 310 is started to drive the cylinder 320 and the strut 300 to rotate, so that one connecting arm 330 rotates to the upper part of the sewage cylinder 100, the cylinder 320 is started to drive the strut 300 to descend, the strut 300 drives the connecting arm 330 and the connecting rod 340 to descend, the filter disc 400 slides downwards in the sewage cylinder 100 to the bottom, in the process, the filter holes 410 are staggered with the dense ring 530, the sewage can directly pass through the filter holes 410, and impurities cannot be intercepted.

After the filter tray 400 is lowered to the bottom, the second motor 350 is started to drive the rotating shaft 360 to rotate, so that the filter screen 500 rotates relative to the filter tray 400, as shown in fig. 3, the sealing rings 530 all rotate to the positions below the filter holes 410 to cover the filter holes 410. When the cylinder 320 is started again, the connecting arm 330 and the supporting rod are lifted by the supporting column 300, and the filter disc 400 also moves upwards, in the process, when the sewage passes through the filter holes 410, the impurities are intercepted by the filter screen 500. After the filter disc 400 leaves the wastewater barrel 100, the first motor 310 is started to drive the prop 300 to rotate, so that the next rotating arm is aligned with the wastewater barrel 100, and the used filter screen 500 can be detached for cleaning and then sequentially goes on, so that the wastewater in the wastewater barrel 100 is filtered for a plurality of times, and the wastewater is purified to the maximum.

Specifically, in order to prevent the filter disc 400 from taking sewage from the wastebasket 100 when the disc 400 is separated from the wastebasket 100, as shown in fig. 4, the upper surface of the filter disc 400 is not planar, the upper surface around each filter hole 410 is recessed toward the filter hole 410, the upper surface of the filter disc 400 has no flat surface, and the sewage flows toward the filter holes 410 during the rising process.

By the arrangement of the sealing block 420, a small part of sewage can be prevented from entering the inside of the connecting rod 340, so that the sewage cannot be filtered.

After the sewage in the sewage cylinder 100 is purified for many times, the drain valve 110 can be opened to flow the water into the clean water tank 200, the top of the clean water tank 200 is provided with the detachable filter layer 210, substances such as activated carbon can be put into the filter layer 210, and organic pollutants which can not be easily removed by the activated carbon have better removal effect, such as chromaticity, peculiar smell, methylene blue surface active substances, a plurality of artificially synthesized organic compounds, and the like. Finally, the purified water may be discharged through the bottom outlet hole 220.

The working principle of the sewage filtering device is as follows: the sewage is poured into the sewage cylinder 100, the first motor 310 is started to rotate the support post 300, one of the connecting arms 330 is aligned with the sewage cylinder 100, the air cylinder 320 is started to lower the support post 300, and the connecting arm 330 and the connecting rod 340 drive the filter disc 400 to move to the bottom of the sewage cylinder 100, so that the sewage cannot be filtered through the filter holes 410 in the process.

After the filter disc 400 reaches the bottom, the second motor 350 is started, the rotating shaft 360 drives the filter screen 500 to rotate, the dense rings 530 on the filter screen 500 correspond to the filter holes 410 one by one, the cylinder 320 is started again, the filter disc 400 rises, impurities can be intercepted by the filter screen 500 when sewage passes through the filter holes 410, and the sewage flows into the filter holes 410 completely and is filtered completely due to the fact that the upper surface of the filter disc 400 is provided with the plurality of inclined surfaces. After the filter tray 400 is removed from the bowl 100, the first motor 310 is activated to rotate the post 300 to align the next connecting arm 330 with the bowl 100 for the next decontamination. In the purification process, the filter screens 500 with different meshes of the dense ring 530 can be arranged according to the sequence, and the impurities are sequentially filtered from large to small, so that the impurities are gradually intercepted layer by layer, and finally the impurity interception effect is optimal. After the purified water in the waste water tank 100 is completed, the drain valve 110 is opened, and the water flows into the purified water tank 200, is filtered for the last time by the filter layer 210, and is discharged from the water outlet hole 220.

Use above-mentioned sewage filter equipment, can carry out filtration treatment many times to sewage with a plurality of clean clear filter disks 400, the filter effect is good to can carry out the filtration of different levels through setting up the different filter screen 500 of specification, make filterable effect reach best.
