Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an efficient sludge and sewage separation device. Background Technique

[0002] In the process of sewage treatment, the separation of sludge and sewage is one of the links. Some of the sludge contained in the sewage can be reused after separation to achieve the recycling of resources. However, most of the traditional sludge and sewage separation methods use centrifugal separation. We found during use that it is not efficient, with low efficiency, and the effect of mud-water separation is not very good. Especially when separating a large mass of sludge, not much water content in the sludge at the center part can be separated, resulting in a poor effect. Content of the Utility Model

[0026] The following further details the embodiments of the present utility model with reference to the attached drawings:

[0027] Please refer to Figure 1-7, an embodiment provided by the present utility model: an efficient sludge and sewage separation device, including a separation box body 10 and a support seat 11. The support seat 11 serves as a support. At the position of the top opening in the inner cavity of the separation box body 10, two grid plates 19 are slidably installed between the front and rear side walls. The grid of the middle of the grid plate 19 is formed by connecting a number of triangular columns 20 in a crisscross manner, such that the triangular edges of the triangular columns 20 face upwards. Moreover, each of the grid plates 19 can pass through the openings on the left and right sides of the separation box body 10. In order to facilitate the coordinated reciprocating movement of the upper and lower grid plates 19, a rack plate 22 is fixedly installed on the front end face of each grid plate 19. A chute 21 is respectively provided on the front end face of the separation box body 10 at the position of each rack plate 22. Each rack plate 22 is slidably connected in the corresponding chute 21. A groove opening is provided between the two chutes 21. Three gear columns 23 are rotatably installed in the groove opening. The gear columns 23 are meshed with the two rack plates 22. The right end face of the separation box body 10 is rotatably connected to a turntable 15 through a rotating shaft. Groove cavities 16 are equidistantly distributed on the turntable 15. An extension part 17 is fixedly provided on the lower grid plate 19. A compression spring is connected between the extension part 17 and the right end face of the separation box body 10. A protrusion part 18 is provided on the extension part 17. The protrusion part 18 can just slide into the groove cavity 16. A support seat 11 is fixedly installed on the outer end face of the separation box body 10. A support plate 13 is fixedly connected to the upper end face of the support seat 11. A driving motor 14 is fixedly installed on the support plate 13. The output end of the driving motor 14 is fixedly connected to the rotating shaft on the turntable 15;

[0028] When the driving motor 14 is started, it will drive the turntable 15 to rotate. The protrusion part 18 slides and fits into the groove cavity 16. Thus, when the turntable 15 rotates, by the cooperation between the groove cavity 16 and the protrusion part 18, the extension part 17 will be driven to achieve a reciprocating movement left and right. Then, through the transmission of the gear columns 23, the upper grid plate 19 will also perform a reciprocating movement left and right. The difference is that the reciprocating movement directions of the two grid plates 19 are opposite. Thus, when the sludge to be separated from mud and water is placed on the upper grid plate 19, the sludge is fully dispersed by the left and right movement of the grid plate 19. At this time, part of the water in the dispersed sludge will drain out and fall to the bottom of the separation box body 10.

[0029] It should be noted that, in order to ensure the movement stability of the grid plate 19, in this embodiment, two fixing plates 24 are respectively and fixedly installed on the front and rear side walls in the inner cavity of the separation box body 10. The lower end of each grid plate 19 is respectively slidably abutted against the corresponding two fixing plates 24.

[0030] It is worth mentioning that in this embodiment, a partition plate 25 is fixedly installed between the front and rear side walls in the inner cavity of the separation box body 10. Guide plates 26 are respectively fixedly installed on the front and rear side walls in the inner cavity of the separation box body 10. The guide plates 26 are located at the lower end of the partition plate 25. A polyester filter screen part 28 is fixedly connected between the two guide plates 26. Two trapezoidal extrusion plates 27 are slidably connected between the two guide plates 26. Hydraulic telescopic machines 12 are respectively fixedly installed on the left and right sides of the separation box body 10 on the upper end surface of the support seat 11. The telescopic ends of each hydraulic telescopic machine 12 are fixedly connected to the corresponding trapezoidal extrusion plate 27 respectively;

[0031] The sludge dispersed by the grid plate 19 falls into the inner cavity surrounded by the guide plates 26 and the polyester filter screen part 28. The two guide plates 26 are inclined. Even if the sludge falls on them, it is not easy to slide due to the viscosity of the sludge, so it will not accumulate on the polyester filter screen part 28. The extra water discharged by hitting the guide plates 26 during the falling process will also flow to the bottom through the polyester filter screen part 28. At this time, control the two hydraulic telescopic machines 12 to start, drive the two trapezoidal extrusion plates 27 to slide towards the middle of the separation box body 10, so that the two trapezoidal extrusion plates 27 extrude the sludge, and finally fully extrude the remaining water in the sludge. After extrusion, control the left hydraulic telescopic machine 12 to retract, and the right hydraulic telescopic machine 12 continues to extend, push the extruded sludge to the upper side of the sludge discharge port 29, and finally reset to let the extruded sludge be discharged from the sludge discharge port 29, while the water in the sludge remains in the right bottom area of the separation box body 10 and the water outlet 30 can be opened for discharge.

[0032] During specific implementation, first place the sludge on the grid plate 19. When the drive motor 14 starts, it will drive the turntable 15 to rotate. The convex part 18 slides and fits into the groove cavity 16. Therefore, when the turntable 15 rotates, by the cooperation between the groove cavity 16 and the convex part 18, it will drive the extension part 17 to achieve a reciprocating left-right movement. Thus, through the transmission of the gear column 23, the upper grid plate 19 also performs a reciprocating left-right movement. The difference is that the reciprocating movement directions of the two grid plates 19 are opposite. Therefore, when placing the sludge to be separated from mud and water on the upper grid plate 19, the sludge is fully dispersed by the left-right movement of the grid plate 19. At this time, part of the water in the dispersed sludge will drain out and fall to the bottom of the separation box 10, while the dispersed sludge falls on the guide plate 26 and the polyester filter screen part 28. The additional water discharged by hitting the guide plate 26 during the falling process will also flow to the bottom through the polyester filter screen part 28. At this time, control the two hydraulic extensors 12 to start, driving the two trapezoidal pressing plates 27 to slide towards the middle of the separation box 10. Thus, the two trapezoidal pressing plates 27 press the sludge, and finally squeeze out the remaining water in the sludge. After squeezing, control the left hydraulic extensor 12 to retract, while the right hydraulic extensor 12 continues to extend, pushing the squeezed sludge to the upper side of the sludge discharge port 29, and finally reset to let the squeezed sludge be discharged from the sludge discharge port 29, and the water in the sludge remains in the right bottom area of the separation box 10 and the water outlet 30 can be opened for discharge.

[0033] It should be emphasized that the embodiments of the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments in the specific implementation manners. Any other implementation manners obtained by those skilled in the art according to the technical solutions of the present invention also belong to the protection scope of the present invention.
