The horizontal cylinder 2, the slag discharge pipe 5 and the annular partition 6 are coaxially arranged, and the cross-sections are all circular. Every two adjacent annular partitions 6 are connected by several filter screens 7, and the filter screens 7 are evenly distributed along the axis of the horizontal cylinder 2. The filter screens 7 are respectively provided with filter mesh holes 8, and the size of the filter mesh holes 8 gradually decreases from the high end to the low end of the horizontal cylinder 2. Water-permeable grooves 9 are respectively provided on the annular partitions 6, and the water-permeable grooves 9 on the left and right adjacent annular partitions 6 are staggered up and down. In this embodiment, two adjacent water-permeable grooves 9 differ by 180°, and a strip-shaped water-permeable groove 10 is provided on the top side of the slag discharge pipe 5. The horizontal cylinder 2 is provided with a driving mechanism that can drive the annular partition 6 to rotate. The present invention has a simple structure and an ingenious design. It utilizes the fluidity of water to gradually enter filter cavities with different filtering accuracies to achieve step-by-step filtration of sewage, and utilizes the rotating filter screen plate 7 to disturb and stir the sewage, so that solid impurities are evenly distributed in the sewage, reducing the aggregation of solid impurities and facilitating the filter screen plate 7 to filter the sewage. At the same time, the filter screen plate 7 can filter out solid impurities to form a filtrate, and utilize the gravity of the filtrate to slide into the slag discharge pipe 5 for discharge. The filtrate can be discharged while filtering, reducing the influence of the filtrate on the filter mesh 8, meeting market demand, and being suitable for promotion.When using the device, firstly, the annular partition plate 6 is driven to rotate by the driving mechanism, and the annular partition plate 6 drives the filter screen plate 7 to rotate, and then the industrial sewage to be filtered is poured into the horizontal cylinder 2 through the water inlet 3, and the sewage enters the water inlet cavity 100. When the leftmost permeable groove 9 is facing, the sewage enters the second filter cavity 200 on the left through the leftmost permeable groove 9, and the filter screen plate 7 placed under the corresponding slag discharge pipe 5 filters the sewage. The sewage passes through the filter mesh 8, and the filtered material rotates with the filter screen plate 7. When the filter screen plate 7 is located above the slag discharge pipe 5, the filtered material slides into the slag discharge pipe 5 through the strip-shaped permeable groove 10. In the pipe 5, due to the inclined design of the horizontal cylinder 2 and the slag discharge pipe 5, the filtered material in the slag discharge pipe 5 is discharged from the right end under the action of its own gravity to complete the coarse filtration. At the same time, the second water-permeable groove 9 on the left side faces downward, and the sewage enters the third filter chamber 200 on the left side for secondary coarse filtration. Similarly, the sewage gradually enters different filter chambers 200 to complete different levels of filtration from coarse to fine. When the filter screen plate 7 rotates with the annular partition plate 6, when the filter screen plate 7 faces downward, it can disturb the sewage, so that the solid impurities in the sewage are distributed in the sewage, reducing the aggregation of solid impurities, and facilitating the filter screen plate 7 to filter the sewage.

When the driving motor 20 is powered on, the output shaft of the driving motor 20 drives the bevel gear 21 to rotate, thereby driving the bevel gear ring 22 and the rightmost annular partition 6 to rotate, and the rightmost annular partition 6 drives the remaining annular partitions 6 and the filter screen plate 7 to rotate along the axis of the slag discharge pipe 5 through the filter screen plate 7.

[0020] Specifically, as shown in the figure, the left end of the slag discharge pipe 5 described in this embodiment is rotatably installed with a partition plate 30, the partition plate 30 is fixedly connected to the outer periphery of the sealing bearing, the inner ring of the sealing bearing is fixedly connected to the slag discharge pipe 5, the partition plate 30 is also coaxially arranged with the slag discharge pipe 5, the partition plate 30 blocks the left end of the slag discharge pipe 5, and the partition plate 30 is also connected to the leftmost annular partition plate 6 through a plurality of filter screen plates 7, the outer periphery of the partition plate 30 is in sliding contact with the inner periphery of the horizontal cylinder 2, and a water inlet permeable groove 31 is provided on the partition plate 30, and the water inlet permeable groove 31 is staggered up and down with the leftmost permeable groove 9 The side of the partition 30 facing away from the slag discharge pipe 5 is slidably matched with the baffle 32, and the right side of the baffle 32 is in sliding contact with the left side of the partition 30.

When the annular partition 6 and the filter screen plate 7 rotate, the partition 30 is driven to rotate, and the partition 30 drives the water inlet groove 31 to rotate. When the water inlet groove 31 is located at the bottom, the water inlet groove 31 overlaps with the water inlet groove 33, and the sewage in the water inlet chamber 100 enters the filter chamber 200 through the water inlet groove 33 and the water inlet groove 31; when the water inlet groove 31 no longer overlaps with the water inlet groove 33, the water in the water inlet chamber 100 stops entering the filter chamber 200, and the baffle 32 cooperates with the partition 30 to control whether the water inlet groove 31 overlaps with the water inlet groove 33, thereby controlling the sewage to enter the filter chamber 200. Even if the water inlet chamber 100 is filled with sewage, the sewage will not always enter the filter chamber 200.

[0021] Further, as shown in the figure, a coaxial horizontal shaft 40 is movably provided in the slag discharge pipe 5 of this embodiment, one end of the horizontal shaft 40 is fixedly connected to the partition 30, and a coaxial spiral blade 41 is fixedly provided on the outer periphery of the horizontal shaft 40, and the outer periphery of the spiral blade 41 is in sliding contact with the inner periphery of the slag discharge pipe 5.

When the strip plate 50 rotates along the axis of the slag discharge pipe 5 with the filter screen plate 7, when the filter screen plate 7 is located at the lower side of the slag discharge pipe 5, under the action of its own gravity, the strip plate 50 slides to the end of the filter screen plate 7 away from the slag discharge pipe 5. When the filter screen plate 7 is located at the upper side of the slag discharge pipe 5, under the action of its own gravity, the strip plate 50 slides to the end of the filter screen plate 7 close to the slag discharge pipe 5. The strip plate 50 can scrape off the filtered material on the side of the filter screen plate 7 and clean the filter screen plate 7, so that the filtered material can fall into the slag discharge pipe 5 through the strip through groove 10.

[0023] Further, as shown in the figure, the strip plate 50 of this embodiment is provided with bristles on one side close to the filter screen plate 7. The bristles fit the filter screen plate 7, which can increase the cleaning effect of the strip plate 50 on the filter screen plate 7.

When the annular partition 6 and the filter screen plate 7 rotate counterclockwise, the larger filter screen holes 8 first contact and cooperate with the sewage, first filter out the larger volume of the filter, and then filter out the smaller volume of the filter, increase the number of filter levels of the filter screen holes 8, and improve the filtering effect and filtering efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
