The adjacent ends of the two arc-shaped magnetic plates 19 are arranged with the same poles. A driving motor 23 is fixedly installed on the top of the filter cylinder 3. The output end of the driving motor 23 passes through the top wall of the filter cylinder 3 and is fixedly installed with the rotation center of the turntable 5. The rotating mechanism includes an incomplete toothed ring 21 fixedly installed on the inner wall of the filter cylinder 3, and a toothed ring 20 is fixedly installed on the outer surface of the mesh cylinder 6 near its top, and the toothed ring 20 is intermittently meshed with the incomplete toothed ring 21.

[0029] When in use, the construction sewage to be treated is concentrated in the liquid storage barrel 4, and the rotating disk 5 is driven to rotate by the driving motor 23, so that the rotating disk 5 drives the mesh drum 6 to rotate. When the mesh drum 6 rotates to the bottom of the liquid storage barrel 4, the sewage in the liquid storage barrel 4 will be poured into the mesh drum 6, so that the mesh drum 6 and the filter disc 8 can filter the impurities in the sewage, and the filtered impurities are temporarily stored in the mesh drum 6. The filtered sewage flows into the sedimentation tank 1 through the discharge pipe 24 for collection, which is convenient for the subsequent flocculation and sedimentation operation of the sewage in the sedimentation tank 1; when the rotating disk 5 drives the mesh drum 6 to rotate to the teeth of the incomplete gear ring 21, the gear ring 20 installed on the outer side of the top of the mesh drum 6 will mesh with the teeth of the incomplete gear ring 21, so that the gear ring 20 can drive the mesh drum 6 to rotate, so as to throw out the sewage in the mesh drum 6, and accelerate the separation efficiency of sewage and impurities; while the mesh drum 6 rotates, the crushing knife 7 fixedly installed on the inner wall of the mesh drum 6 can break up the larger mud blocks and other impurities in the sewage for subsequent discharge operations.

[0030] In this embodiment, the magnetic attraction mechanism includes two vertical plates 13 symmetrically fixedly installed on the lower surface of the turntable 5, the two vertical plates 13 are arranged on both sides of the net cylinder 6, and the outer surfaces of the two vertical plates 13 are horizontally penetrated by two guide rods 14 for sliding installation, and the ends of the two guide rods 14 on the same side close to the net cylinder 6 are fixedly installed with arc-shaped magnetic plates 19, and the upper surface of the filter disc 8 is respectively penetrated by the first discharge port 9 and the second discharge port 10, and the end of the guide rod 14 away from the arc-shaped magnetic plate 19 is installed with a closing component, and the closing component includes a guide groove fixedly installed on the end of the guide rod 14 away from the arc-shaped magnetic plate 19 Plate 15, the inner wall of the guide groove plate 15 is slidably mounted with a guide column 17, the outer surface of the guide column 17 is fixedly mounted with a support rod 16, an extrusion assembly is installed between the support rod 16 and the filter cylinder 3, the extrusion assembly includes a push rod 18 fixedly mounted on the outer surface of the support rod 16 away from the mesh cylinder 6, the inner wall of the filter cylinder 3 close to the first discharge port 9 is fixedly mounted with an arc guide plate 22, the end of the push rod 18 is intermittently slidably mounted with the side of the arc guide plate 22, the end of the arc guide plate 22 is a sloped structure, which is convenient for guiding the push rod 18 so that the end of the push rod 18 can move to the side of the arc guide plate 22.

[0031] When the turntable 5 drives the two arc-shaped magnetic plates 19 corresponding to the outside of the net cylinder 6 and the support rod 16 to rotate as a whole to the arc-shaped guide plate 22, the tooth ring 20 is separated from the teeth of the incomplete tooth ring 21, and the net cylinder 6 stops rotating. The push rod 18 installed on the outside of the support rod 16 will move to the side of the arc-shaped guide plate 22, so that the push rod 18 can drive the support rod 16 and the guide column 17 to move as a whole in the direction of the net cylinder 6, so that the guide column 17 pushes the guide groove plate 15, so that the guide groove plate 15 can push the arc-shaped magnetic plate 19 in the direction of the net cylinder 6 through the guide rod 14, so that the arc-shaped magnetic plate 19 fits on the outside of the net cylinder 6, and the iron impurities such as the iron nails inside the net cylinder 6 are adsorbed on the cylinder wall. When the net cylinder 6 moves to the first discharge port 9 opened on the filter disc 8, the net cylinder 6 does not contain The iron impurities will automatically fall onto the discharge net bucket 11 through the first discharge port 9 and be discharged from the filter cylinder 3; when the net cylinder 6 is completely moved above the second discharge port 10, the top rod 18 will be separated from the side of the arc guide plate 22. Since the adjacent ends of the two arc-shaped magnetic plates 19 are arranged with the same poles, according to the principle that the same poles of magnets repel each other, the repulsive force between the ends of the two arc-shaped magnetic plates 19 can automatically push the two arc-shaped magnetic plates 19 away from each other, so that the two arc-shaped magnetic plates 19 no longer fit the outer side of the net cylinder 6, so that the iron impurities adsorbed on the inner wall of the net cylinder 6 lose their attraction and automatically fall onto the discharge net bucket 11 through the second discharge port 10, and the iron impurities are discharged from the filter cylinder 3 through the discharge net bucket 11, which is convenient for the subsequent collection and reuse of the iron impurities.

[0032] In this embodiment, a discharge groove is formed through the outer surface of the filter cylinder 3 near the first discharge port 9 and the second discharge port 10, and a discharge net bucket 11 is fixedly installed at an angle on the inner wall of the discharge groove. A small amount of sewage on the surface of the filter disc 8 that is not discharged into the sedimentation tank 1 through the discharge pipe 24 in time will flow onto the discharge net bucket 11, so that the discharge net bucket 11 can discharge the sewage into the filter cylinder 3 to prevent the sewage from overflowing the filter cylinder 3. A partition 12 is fixedly installed on the inner wall of the discharge net bucket 11 to separate the first discharge port 9 and the second discharge port 10, and the interior of the discharge net bucket 11 is separated by the partition 12 to facilitate the subsequent collection of ordinary impurities and iron impurities.

[0033] In this embodiment, a plurality of crushing knives 7 are evenly and fixedly installed on the inner wall of the net cylinder 6; while the net cylinder 6 rotates, the crushing knives 7 fixedly installed on the inner wall of the net cylinder 6 can break up larger impurities such as mud in the sewage for subsequent discharge operations.

[0034] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the construction sewage to be treated is concentrated in the liquid storage barrel 4, and the turntable 5 is driven to rotate by the driving motor 23, so that the turntable 5 drives the mesh cylinder 6 to rotate, and when the mesh cylinder 6 rotates to the bottom of the liquid storage barrel 4, the sewage in the liquid storage barrel 4 will be poured into the mesh cylinder 6, so that the mesh cylinder 6 and the filter disc 8 can filter the impurities in the sewage, and the filtered impurities are temporarily stored in the mesh cylinder 6. The filtered sewage flows into the sedimentation tank 1 through the drain pipe 24 for collection, which is convenient for the subsequent flocculation and sedimentation operation of the sewage in the sedimentation tank 1;

[0035] When the turntable 5 drives the net cylinder 6 to rotate to the teeth of the incomplete toothed ring 21, the toothed ring 20 installed on the outer side of the top of the net cylinder 6 will mesh with the teeth of the incomplete toothed ring 21, so that the toothed ring 20 can drive the net cylinder 6 to rotate, so as to throw out the sewage in the net cylinder 6, thereby accelerating the separation efficiency of sewage and impurities; while the net cylinder 6 rotates, the crushing knife 7 fixedly installed on the inner wall of the net cylinder 6 can break up the larger impurities such as mud in the sewage for subsequent discharge operations;

[0036] When the turntable 5 drives the two arc-shaped magnetic plates 19 corresponding to the outside of the net cylinder 6 and the support rod 16 to rotate as a whole to the arc-shaped guide plate 22, the tooth ring 20 is separated from the teeth of the incomplete tooth ring 21, and the net cylinder 6 stops rotating. The push rod 18 installed on the outside of the support rod 16 will move to the side of the arc-shaped guide plate 22, so that the push rod 18 can drive the support rod 16 and the guide column 17 to move as a whole in the direction of the net cylinder 6, so that the guide column 17 pushes the guide groove plate 15, so that the guide groove plate 15 can push the arc-shaped magnetic plate 19 in the direction of the net cylinder 6 through the guide rod 14, so that the arc-shaped magnetic plate 19 fits on the outside of the net cylinder 6, and the iron impurities such as the iron nails inside the net cylinder 6 are adsorbed on the cylinder wall. When the net cylinder 6 moves to the first discharge port 9 opened on the filter disc 8, the net cylinder 6 does not contain The iron impurities will automatically fall onto the discharge net bucket 11 through the first discharge port 9 and be discharged from the filter cylinder 3; when the net cylinder 6 is completely moved to the top of the second discharge port 10, the top rod 18 will be separated from the side of the arc guide plate 22. Since the adjacent ends of the two arc magnetic plates 19 are arranged with the same pole, according to the principle that the same poles of magnets repel each other, the repulsive force between the ends of the two arc magnetic plates 19 can automatically push the two arc magnetic plates 19 away from each other, so that the two arc magnetic plates 19 no longer fit the outer side of the net cylinder 6, so that the iron impurities adsorbed on the inner wall of the net cylinder 6 lose their attraction and automatically fall onto the discharge net bucket 11 through the second discharge port 10, and the iron impurities are discharged from the filter cylinder 3 through the discharge net bucket 11, so as to facilitate the subsequent collection and reuse of the iron impurities.

[0037] The sewage is continuously filtered through the mesh cylinder 6, and the filtered common impurities are separated from the iron impurities and then discharged and collected, which can avoid impurities clogging the filter disc 8 and the mesh cylinder 6, improve the filtering treatment effect of construction sewage, and facilitate the subsequent flocculation and sedimentation of the sewage collected in the sedimentation tank 1 for reuse.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
