[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a sludge filter press dewatering machine, including a dewatering machine box 1. A filter press cylinder 5 is fixedly installed inside the dewatering machine box 1. Protective side plates 9 are symmetrically fixedly installed on both sides below the filter press cylinder 5. A push plate 10 is provided at the rear end between the two protective side plates 9. A sludge discharge inclined plate 4 is fixedly installed at the front end between the two protective side plates 9. A sludge discharge trough 101 is provided on the front end face of the dewatering machine box 1. One end of the sludge discharge inclined plate 4 extends to the outside of the dewatering machine box 1 through the sludge discharge trough 101. A lifting plate 15 is provided at the lower part of the filter press cylinder 5. A pressure plate 6 is provided at the upper part of the filter press cylinder 5.

[0024] The sludge is fed into the filter press cylinder 5, and then the pressure plate 6 is driven to move down to filter the sludge. The filtered sludge is compacted and remains on the lifting plate 15. The lifting plate 15 is then driven to move down so that the upper end of the lifting plate 15 is flush with the lower end of the push plate 10. The push plate 10 is then driven to move forward so that the sludge on the lifting plate 15 is pushed and discharged from the dewatering chamber 1 through the sludge discharge inclined plate 4. This avoids the tediousness and inconvenience of manual operation, improves cleaning efficiency, and increases practicality.

[0025] Please see Figure 2 and Figure 3 A sludge input pipe 2 is fixedly installed on the upper side of one side of the filter press cylinder 5, and one end of the sludge input pipe 2 extends to the outside of the dewatering chamber 1. A filter press chamber 501 is provided inside the filter press cylinder 5, and the sludge input pipe 2 is connected to the filter press chamber 501.

[0026] The sludge input pipe 2 allows sludge to be conveniently input from outside the dewatering chamber 1 into the filter press chamber 501 of the filter press cylinder 5, realizing the automation and convenience of sludge input and improving the efficiency of sludge input.

[0027] Please see Figure 2 and Figure 3 A drainage chamber 502 is provided inside the filter press cylinder 5 along the outer side of the filter press chamber 501. A permeable plate 14 is fixedly installed inside the filter press cylinder 5 between the filter press chamber 501 and the drainage chamber 502. A drainage pipe 3 is fixedly installed on the lower side of one side of the filter press cylinder 5. The drainage pipe 3 is connected to the drainage chamber 502, and one end of the drainage pipe 3 extends to the outside of the dewatering machine box 1.

[0028] The arrangement of the drainage chamber 502 and the permeable plate 14 allows the water generated during the filter press process to quickly flow into the drainage chamber 502 through the permeable plate 14 and be discharged to the outside of the dewatering chamber 1 through the drainage pipe 3, effectively achieving solid-liquid separation and improving the dewatering effect of sludge.

[0029] Please see Figure 2 A hydraulic cylinder 7 is fixedly installed in the middle of the upper part of the dewatering machine box 1. The piston rod end of the hydraulic cylinder 7 slides into the interior of the dewatering machine box 1 and is fixedly connected to the pressure plate 6. Guide columns 8 are symmetrically arranged on both sides of the hydraulic cylinder 7. The lower end of the guide column 8 slides into the interior of the dewatering machine box 1 and is fixedly connected to the pressure plate 6.

[0030] The hydraulic cylinder 7 and guide column 8 enable the pressure plate 6 to move stably up and down under the drive of the hydraulic cylinder 7, thereby realizing the sludge filtration operation. The design of the guide column 8 ensures the stability and accuracy of the pressure plate 6 during the movement process, and avoids the pressure plate 6 from shifting or shaking during the filtration process.

[0031] Please see Figure 2 and Figure 3 A base frame 11 is fixedly installed at the bottom inside the dehydrator housing 1. The base frame 11 is a U-shaped plate. A hydraulic cylinder 12 is fixedly installed inside the base frame 11. The piston rod end of the hydraulic cylinder 12 slides to the top of the base frame 11 and is fixedly connected to the lifting plate 15. Guide columns 13 are symmetrically arranged on both sides of the hydraulic cylinder 12. The upper end of the guide column 13 slides to the top of the base frame 11 and is fixedly connected to the lifting plate 15.

[0032] The base frame 11, hydraulic cylinder 2 12, and guide column 2 13 enable the lifting plate 15 to move stably up and down under the drive of hydraulic cylinder 2 12, thus facilitating the removal of the filtered sludge from the filter press cylinder 5. The U-shaped plate design gives the base frame 11 better structural strength and stability, enabling it to bear the weight of the lifting plate 15 and the sludge. The design of guide column 2 13 ensures the stability and accuracy of the lifting plate 15 during movement.

[0033] Please refer to the figure. Figure 3 and Figure 4 A hydraulic cylinder 316 is fixedly installed at the rear end of the dewatering machine box 1. The piston rod end of the hydraulic cylinder 316 slides into the interior of the dewatering machine box 1 and is fixedly connected to the push plate 10. Guide pillars 317 are symmetrically arranged on both sides of the hydraulic cylinder 316. One end of the guide pillar 317 slides into the interior of the dewatering machine box 1 and is fixedly connected to the push plate 10.

[0034] The hydraulic cylinder 16 and guide column 17 enable the push plate 10 to move stably back and forth under the drive of the hydraulic cylinder 16, thereby outputting the sludge on the lifting plate 15 from the dewatering chamber 1 through the sludge discharge inclined plate 4. The design of the guide column 17 ensures the stability and accuracy of the push plate 10 during movement, and avoids the push plate 10 from deviating or shaking during the process of pushing the sludge.

[0035] Working principle: During use, sludge is input from the outside of the dewatering chamber 1 into the filter chamber 501 of the filter press cylinder 5 through the sludge input pipe 2, realizing the automation of sludge input. Subsequently, hydraulic cylinder 7 drives the pressure plate 6 to move down, performing a sludge filtration operation. The water generated during the filtration process flows into the drainage chamber 502 through the permeable plate 14 and is discharged to the outside of the dewatering chamber 1 through the drainage pipe 3, realizing solid-liquid separation. After the filtration is completed, the sludge after filtration is compacted and remains on the lifting plate 15. Then, hydraulic cylinder 12 drives the lifting plate 15 to move down, and hydraulic cylinder 16 drives the push plate 10 to move forward, so that the sludge on the lifting plate 15 is discharged from the sludge discharge trough 101 in the dewatering chamber 1 through the sludge discharge inclined plate 4, completing the sludge cleaning operation.
