In order to better allow the sewage to enter the interior of the filter 2, the right end of the pipe 5 is sealed.

When the present invention is used, the sewage is firstly entered through the left end of the pipeline 5 along the pipeline 5; since the pipeline 5 is provided with a plurality of water outlets 6, the sewage will flow out through the plurality of water outlets 6 and fall into the interior of the filter 2 ; Since the left and right sides of the filter 2 are provided with end caps 204, the sewage will be blocked in the interior of the filter 2. When the sewage enters the interior of the filter 2, the arc-shaped plate 207 at the bottom is under the influence of gravity. Under the action, it will be in a state away from the filter cartridge 201, that is, the hydrophobic hole 202 on the filter cartridge 201 is open. At this time, the sewage can be filtered through the hydrophobic hole 202, and the filtered water will flow into the sump 3, and the impurities The filtrate will remain in the interior of the filter cartridge 201; the filtered water will wash the arc-shaped plate 207 when it flows downward after being filtered, but since the sewage has been filtered at this time, there will be no debris left on the arc-shaped plate 207; Although the plate 207 blocks the sewage, the sewage can still flow into the sump 3 .

With the rotation of the filter 2, at this time, under the action of the baffle 203, the baffle 203 will move the sundries and rotate upward with the filter 2; referring to FIG. There is a fan-shaped plate 401; therefore, when the sundries are rotated to the horizontal position and continue to rotate upward, the sundries will be blocked by the fan-shaped plate 401 to avoid falling directly; during this process, the sewage contained in the sundries will also It flows downward from the gap and flows into the water collecting tank 3, thereby reducing the content of sewage in the sundries, especially some of the sundries similar to a dish, so that the internal sewage can be automatically discharged.

When the filter 2 continues to rotate, the baffle plate 203 originally located at the bottom gradually rotates to the highest point. At this time, the fan-shaped plate 401 is not blocking the sundries, and the sundries will fall directly on the deflector plate 7 under the action of gravity. At the same time, due to the self-weight of the arc-shaped plate 207 and the action of the counterweight block 206 at the inner end of the support rod 205, the arc-shaped plate 207 at the top at this time will descend, and the ejector pins 208 on the inner surface of the arc-shaped plate 207 will be inserted into the In the hydrophobic hole 202 of the filter cartridge 201, the debris remaining on the inner surface of the filter cartridge 201 is pushed off; the debris is prevented from remaining on the inner edge surface of the filter cartridge 201; thus, the self-cleaning of the filter cartridge 201 is realized.

When the sundries fall on the deflector 7, at this time, since the eccentric wheel 13 is in a state of constant rotation, the eccentric wheel 13 will squeeze the push rod 10, because the lower end of the push rod 10 is on the right end of the deflector 7 The side is hinged, and the hinge of the deflector 7 is on the shunt plate, so after the push rod 10 moves down, the right end of the deflector 7 will drop, and the left end will rise, so that the sundries move to the right; when the eccentric wheel 13 Continue to rotate, at this time, the push rod 10 will reset upward under the action of the tension spring 15, and at the same time drive the right end of the deflector 7 to rise and the left end to drop; , and since the left end of the deflector 7 is provided with a vertical plate 9, the sundries will slide out from the right end of the deflector 7; The collection and processing of statistics; the automatic exclusion of sundries is realized.

In addition, when the deflector 7 is hinged, the length of the left side of the deflector 7 can be smaller than the length of the right side, so that when the deflector 7 swings, the sundries can be better separated.

The reciprocation of the above process can achieve the effect of continuity, the filtered sewage and sundries can flow out through different channels respectively, and the filter cartridge 201 can also be dredged evenly, avoiding clogging.

This device is suitable for all kinds of sewage treatment sites, especially municipal sewage plants, or sewage discharged from various manufacturing factories, or sewage generated by agriculture, forestry, animal husbandry and other industries. This device can be used for rapid treatment. Cost saving and easy maintenance; especially for sewage that is easy to block the filter screen, such as sewage containing a lot of sludge or small particles, it can be blocked.

The device realizes cyclic filtration by passing the sewage into the interior of the rotatable filter 2, specifically, filtering when it is below, and cleaning when it is above, so as to realize the timely cleaning of the filter cartridge 201; work, and the cleaning of the filter cartridge 201 is ensured, and the filtering effect and quality are improved.

In this device, the distributing plate 4 is arranged, so that after the sewage is filtered below, the sundries can follow the rotation of the filter 2 and fall on the top of the flat plate 402, and then through the inclined arrangement of the whole device, the sundries can automatically move along the flat plate 402. Sliding down, the filtered sewage and the sundries can flow out in two ways, realizing real-time filtration and real-time cleaning, avoiding the accumulation of sundries, and no need to stop the machine to clean the sundries. At the same time, the fan-shaped plates 401 on the front and rear sides of the dividing plate 4 can play the role of blocking the sundries, so that the sundries can only fall after they are rotated to the top. In the middle process, slow dehydration can be carried out to reduce the water content.
