[0002] With the progress of society and the development of industry, the discharge of sewage sludge has also increased. The generated sludge has the potential to pollute the environment, so sludge treatment is necessary. Sludge dewatering is the first step in sludge treatment. Sludge dewatering is a sludge treatment method that converts the mud-water mixture into semi-solid or solid mud blocks.

[0003] Most existing sludge dewatering devices use compression or centrifugal methods for dewatering. During this period, a mesh plate is often needed to intercept the sludge. As the mesh plate is used, sludge will adhere to the inner wall of the mesh plate. This sludge will block the flow of water and reduce the filtration efficiency. At this time, personnel are often required to manually clean the mesh plate, and often flush it with water, which not only wastes water resources, consumes manpower and slows the cleaning speed.

[0029] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0030] Example 1, see Figures 1 to 10 As shown, a sludge dewatering device for water supply and drainage includes a base 1, the base 1 is fixedly connected to a controller, and further includes:

[0031] A sewage collection structure 2 connected to the base 1, the sewage collection structure 2 includes a sewage cover 3 fixedly connected to the base 1, the sewage cover 3 is fixedly connected to a sewage valve 4, and the sewage cover 3 is rotatably connected to a mud collection part 5;

[0032] A rotating mud filter structure 6 connected to the base 1 includes a mud collecting trough 7 fixedly connected to the base 1. The base 1 is connected to a rotating telescopic portion 8, which is connected to a rotating flip portion 9. The rotating telescopic portion 8 is used to adjust the height and rotation angle of the rotating flip portion 9. The rotating flip portion 9 is connected to four groups of mesh plates 10. The rotating flip portion 9 is used to apply a rotational driving force to the mesh plates 10 and adjust the relative positions between the mesh plates 10. The mesh plates 10 are provided with densely arranged filter holes. The four groups of mesh plates 10 are movably connected to the mud collecting portion 5.

[0033] A muddy and water guiding structure 11 is connected to the rotating and flipping part 9 .

[0034] When in use, the mud collecting part 5 is connected to an external mud storage device, the sewage valve 4 is connected to an external drainage pipe, and the mud and water guiding structure 11 is connected to the hose of the external sludge supply device. The mud and water guiding structure 11 guides the mud and water to the chamber enclosed by the mesh plate 10 and the mud collecting part 5. The mesh plate 10 intercepts the sludge, and the rotating flip part 9 drives the mesh plate 10 to rotate. The rotating mesh plate 10 drives the mud collecting part 5 to rotate, thereby centrifuging the water in the sludge out of the sludge to achieve mud-water separation. The mud collecting part 5 transports the sludge to the external mud storage device, and the sewage valve 4 is opened for drainage. When the mesh plate 10 needs to be cleaned, the rotating telescopic part 8 drives the rotating The dynamic flip part 9 moves, so that the rotating flip part 9 drives the mesh plate 10 away from the sewage cover 3 and moves toward the mud collecting tank 7, and then the rotating flip part 9 drives the mesh plate 10 to rotate, and the mesh plates 10 rotate in the direction away from each other, so that the four groups of mesh plates 10 are radially expanded, and the lower ends of the mesh plates 10 are away from each other, and then the rotating flip part 9 drives the mesh plates 10 to rotate. At this time, as the rotation speed of the mesh plates 10 increases, the sludge on the mesh plates 10 is thrown away into the mud collecting tank 7. Since the lower ends of the mesh plates 10 are away from each other, the distance between the lower ends of the mesh plates 10 and the rotation center increases, so as to further increase the rotational linear speed of the lower ends of the mesh plates 10, and further facilitate the sludge on the mesh plates 10 to be thrown away. The present invention performs mud and water separation operations by cooperating with the sewage collection structure 2, the rotating filter mud structure 6, and the mud and water guiding structure 11, and automatically performs the cleaning operation of the mesh plates 10, which is convenient, water-saving, and has a fast cleaning speed.

When performing mud-water separation operations, the inner recess 14 and the frame 15 are in contact with the mesh plate 10, so that the inner recess 14, the frame 15, and the mesh plate 10 jointly enclose a space for intercepting sludge. As the mud pump 12 is started, the sludge deposited in the inner recess 14 falls into the mud pump 12 through the rotary joint 13, and then the mud pump 12 extracts the sludge, thereby transporting the deposited sludge.

This prevents the inner recess 14 from rotating when the screen 10 is separated from the inner recess 14 and the frame 15, thereby facilitating the accurate reinstallation of the screen 10 between the frame 15.
