[0034] Such as Figures 1-3As shown in the figure, the present application provides a precipitation device, including a sedimentation tank 1, a silt removal component 2, a horizontal extrusion component 3, a vertical extrusion component 4, a horizontal drive component 5 and a vertical drive component 6. The silt removal component 2 is arranged at the bottom inside the sedimentation tank 1 and is adjacent to an inner side wall of the sedimentation tank 1. The horizontal extrusion component 3 is arranged inside the sedimentation tank 1. The horizontal extrusion component 3 is used to horizontally push the wastewater in the sedimentation tank 1 towards the silt removal component 2 and filter and extrude the impurity particles in the wastewater. The vertical extrusion component 4 is arranged on the horizontal extrusion component 3. The vertical extrusion component 4 is used to vertically push the wastewater in the sedimentation tank 1 towards the silt removal component 2 and filter and extrude the impurity particles in the wastewater. The horizontal drive component 5 is arranged on the sedimentation tank 1. The horizontal drive component 5 is used to drive the horizontal extrusion component 3 to approach or move away from the silt removal component 2. The vertical drive component 6 is arranged on the horizontal extrusion component 3. The vertical drive component 6 is used to drive the vertical extrusion component 4 to move up and down. When in use, after pouring the wastewater into the sedimentation tank 1, the horizontal drive component 5 drives the horizontal extrusion component 3 to approach the silt removal component 2. The horizontal extrusion component 3 horizontally pushes the wastewater in the sedimentation tank 1 towards the silt removal component 2 and filters and extrudes the impurity particles in the wastewater. Then the vertical drive component 6 drives the vertical extrusion component 4 to move downward. The vertical extrusion component 4 vertically pushes the wastewater in the sedimentation tank 1 towards the silt removal component 2 and filters and extrudes the impurity particles in the wastewater, so that the impurities in the wastewater approach the silt removal component 2 and quickly gather and precipitate. Finally, they are discharged through the silt removal component 2, effectively improving the precipitation efficiency of the impurity particles in the wastewater, ensuring the normal progress of the production process, and improving the production efficiency.

[0035] As Figure 1 and Figure 2 shown, the silt removal component 2 includes a screw conveyor 21 and a silt removal motor 22. The screw conveyor 21 is rotatably arranged inside the sedimentation tank 1. One end of the screw conveyor 21 extends outside the sedimentation tank 1 and is connected to the output shaft of the silt removal motor 22. A silt removal pipe 7 is arranged below the screw conveyor 21 at the bottom of the sedimentation tank 1. A silt removal valve 8 is arranged on the silt removal pipe 7. Among them, a sealing ring is arranged at the connection between the screw conveyor 21 and the sedimentation tank 1 to prevent the wastewater from leaking out through the gap between the screw conveyor 21 and the sedimentation tank 1. By opening the silt removal valve 8 and starting the silt removal motor 22, the silt removal motor drives the screw conveyor 21 to rotate, and conveys the precipitated impurity particles in the sedimentation tank 1 to the silt removal pipe 7, and discharges them through the silt removal pipe 7.

[0036] As Figures 1-3 shown, the horizontal extrusion component 3 includes a horizontal extrusion frame 31 and a first filter cloth 32. The horizontal extrusion frame 31 is slidably arranged inside the sedimentation tank 1. The first filter cloth 32 is fixedly arranged on the side of the horizontal extrusion frame 31 close to the silt removal component 2. When the horizontal extrusion component 3 moves towards the silt removal component 2, the horizontal extrusion frame 31 drives the first filter cloth 32 to move towards the silt removal component 2, filters the impurity particles in the wastewater and pushes them towards the silt removal component 2, and at the same time cooperates with the inner side wall of the sedimentation tank 1 to extrude the impurity particles in the wastewater.

[0037] AsFigure 2 and Figure 3 As shown in Figure 3 , the longitudinal extrusion assembly 4 includes a longitudinal extrusion frame 41 and a second filter cloth 42. A longitudinal guide groove 9 is provided on the transverse extrusion frame 31. One end of the longitudinal extrusion frame 41 is slidably disposed in the longitudinal guide groove 9. The second filter cloth 42 is fixedly provided at the bottom of the longitudinal extrusion frame. After the transverse extrusion assembly 3 laterally extrudes the impurity particles in the wastewater, the longitudinal extrusion assembly 4 moves downward. The longitudinal extrusion frame drives the second filter cloth 42 to move downward, filtering and pushing the impurity particles in the wastewater towards the sludge discharge assembly 2. At the same time, in cooperation with the inner side wall, bottom wall of the sedimentation tank 1 and the transverse extrusion assembly 3, the impurity particles in the wastewater are extruded.

[0038] As Figure 1 and Figure 2 As shown in Figure 2 , the transverse driving assembly 5 includes a transverse driving motor 51 and a transverse threaded rod 52. The transverse threaded rod 52 is rotatably disposed on the top of the sedimentation tank 1. The transverse driving motor 51 is fixedly provided on the top of the sedimentation tank 1. One end of the transverse threaded rod 52 is connected to the output shaft of the transverse driving motor 51. The transverse threaded rod 52 penetrates through the upper part of the transverse extrusion frame 31 and is threadedly connected to the transverse extrusion frame 31. Specifically, the transverse driving motor 51 drives the transverse threaded rod 52 to rotate, thereby causing the transverse extrusion frame 31 to move laterally in the sedimentation tank 1.

[0039] As Figure 2 and Figure 3 As shown in Figure 3 , the longitudinal driving assembly 6 includes a longitudinal driving motor 61 and a longitudinal threaded rod 62. The longitudinal threaded rod 62 is rotatably disposed on one side of the transverse extrusion frame 31 close to the sludge discharge assembly 2. The longitudinal driving motor 61 is fixedly provided on the transverse extrusion frame 31. The upper end of the longitudinal threaded rod 62 is connected to the output shaft of the longitudinal driving motor 61. The longitudinal threaded rod 62 penetrates through the longitudinal extrusion frame and is threadedly connected to the longitudinal extrusion frame. Specifically, the longitudinal driving motor 61 drives the longitudinal threaded rod 62 to rotate, thereby causing the longitudinal extrusion frame to move longitudinally in the sedimentation tank 1. When the longitudinal extrusion frame moves, it moves along the longitudinal guide groove 9, and the movement is stable.

[0040] As Figure 1 and Figure 3 As shown in Figure 3 , guide shafts 10 are fixedly provided on both the front and rear sides of the transverse extrusion frame 31. Transverse guide grooves 11 adapted to the guide shafts 10 are provided on the upper part of the inner wall of the sedimentation tank 1. When the transverse extrusion frame 31 moves, it moves along the transverse guide grooves 11 through the guide posts, and the movement is stable.

[0041] As Figure 2 and Figure 3As shown in the figure, first cleaning brushes 12 are fixedly installed on both the front and rear sides of the horizontal extrusion frame 31. The bristles of the first cleaning brushes 12 are in contact with the inner side wall of the sedimentation tank 1. Second cleaning brushes 13 are fixedly installed on the side of the longitudinal extrusion frame away from the horizontal extrusion frame 31 and on both the front and rear sides. The bristles of the second cleaning brushes 13 are in contact with the inner side wall of the sedimentation tank 1. When the horizontal extrusion frame 31 moves, it drives the first cleaning brushes 12 to move, cleaning the front and rear inner side walls of the sedimentation tank 1. When the longitudinal moving frame moves, it drives the second cleaning brushes 13 to move, cleaning the side wall close to the stasis drainage assembly, preventing impurity particles from adhering to the side wall of the sedimentation tank 1.

[0042] As Figure 2 shown, a drain pipe 14 is provided on one side of the sedimentation tank 1, and a drain valve 15 is provided on the drain pipe 14. By opening the drain valve 15, the treated wastewater can be discharged from the sedimentation tank 1 for further processing in the next process.

[0043] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
