Description

A high-efficiency high-pressure plate and frame dewatering machine for domestic sewage sludge Technical Field

[0001] This utility model relates to the field of plate and frame dewatering machines, specifically a high-efficiency high-pressure plate and frame dewatering machine for domestic sewage sludge. Background Technology

[0002] Plate and frame dewatering machines are commonly used for solid-liquid separation. They mainly remove moisture from water-containing materials through mechanical means and are widely used in industries such as chemical, environmental protection, food, and pharmaceutical.

[0003] Plate and frame dewatering machines consist of plates and frames, filter plates, a pressure system, and liquid discharge pipes. The working principle of the dewatering machine is usually to use pressure filtration, combined with the structure of plates and frames and filter cloth, so that the liquid is discharged through the filter cloth, while the solid matter is retained between the filter plates and frames. Plate and frame dewatering machines have a simple structure, are easy to operate, have strong processing capacity, and good dewatering effect. Depending on different application fields, plate and frame dewatering machines can also be customized in size and filter cloth material according to requirements.

[0004] In the existing technology, after the plate and frame dewatering machine has finished dewatering domestic sludge, the dewatered sludge plates need to be removed from the plate and frame for unloading. However, during unloading, sludge lumps are easily left on the surface of the plate and frame of the existing plate and frame dewatering machine, which requires manual cleaning by the staff. This not only increases the workload of the staff, but also reduces the dewatering efficiency of the sludge. Summary of the Invention

The upper end of the mounting frame 1 is equipped with a toothed plate 14, and the multiple sets of limiting shafts 10 are movably connected to the toothed plate 14. The bottom end of the mounting frame 1 is equipped with a collection box 20. The two sets of cleaning plates 8 are displaced, and the two sets of cleaning plates 8 clean the inner walls of both sides of the dewatering frames 8 respectively. The bottom ends of the inner walls of both sides of the multiple sets of dewatering frames 6 are inclined, which improves the cleaning effect of mud.

[0037] A hydraulic pump 2 is installed at one end of the mounting frame 1, and a hydraulic column 3 is installed at the output end of the hydraulic pump 2. A pressure plate 4 is installed at one end of the hydraulic column 3, and the pressure plate 4 is movably connected to a set of dewatering frames 6. A sludge pipe 21 is installed at one end of the mounting frame 1, and the sludge pipe 21 is connected to a domestic sludge conveying device. A water outlet pipe is installed inside the mounting frame 1, and the water supply pipe is connected to multiple sets of dewatering frames 6. The sludge pipe 21 conveys the domestic sludge to the multiple sets of dewatering frames 6, and the multiple sets of dewatering frames 6 remove the water from the domestic sludge. Then the water is discharged through the water outlet pipe.

[0038] Please refer to Figures 1-4. Support plates 5 are symmetrically installed on the outer walls of the pressure plate 4 and the multiple sets of dewatering frames 6. The cross-section of the multiple sets of support plates 5 is "L". Support columns 13 are symmetrically installed on the inner wall of the mounting frame 1. The outer walls of the two sets of support columns 13 are movably connected to the inner walls of the multiple sets of support plates 5. The two sets of support columns 13 support the multiple sets of support plates 5 respectively, thereby improving the stability of the pressure plate 4 and the multiple sets of dewatering frames 6.

[0039] Please refer to Figures 1-3. The inner wall of the mounting bracket 1 is symmetrically equipped with drive shafts 17, and the two sets of drive shafts 17 are connected by a synchronous belt. One end of the mounting bracket 1 is equipped with a drive motor 16, and the output end of the drive motor 16 is connected to a set of drive shafts 17. When the drive motor 16 starts, it drives a set of drive shafts 17 to rotate. The two sets of drive shafts 17 are connected by a synchronous belt, and the two sets of drive shafts 17 rotate synchronously.

[0040] Please refer to Figures 1-3. Auxiliary plates 15 are symmetrically installed on the inner wall of the mounting bracket 15. Movable seats 18 are movably installed on the upper end of each of the two sets of auxiliary plates 15. The inner walls of the two sets of movable seats 18 are threadedly connected to the outer walls of the two sets of drive shafts 17. The two sets of auxiliary plates 15 support the two sets of movable seats 18 respectively. When the two sets of drive shafts 17 rotate, they drive the two sets of movable seats 18 to move.

[0041] Please refer to Figures 3-7. Limiting plates 7 are installed at the bottom of multiple sets of support plates 5. Push plates 19 are movably installed on the upper ends of multiple sets of movable seats 18, and the push plates 19 are movably connected to the limiting plates 7. Each set of movable seats 18 has bearings connected to the inner walls of the push plates 19, and each bearing has a torsion spring at one end. Displacement of the two sets of movable seats 8 causes displacement of the two sets of push plates 19. The push plates 19 move to one side of the two limiting plates 7, where the limiting plates 7 block one end of each push plate 19, causing the push plates 19 to rotate. The push plates 19 rotate into the inner wall of the movable seat 18, and then move to the other side of the limiting plates 7. The torsion springs at one end of the bearings inside the two sets of movable seats 18 reset the push plates 19.

[0042] Please refer to Figures 3-6. Each of the multiple sets of dehydration frames 6 has a drive shaft 11 movably installed on its inner wall. Each of the multiple sets of drive shafts 11 extends to one end of the outer wall of the multiple sets of dehydration frames 6 and has a drive gear 12 installed thereon. Each of the multiple sets of drive gears 12 is meshed with a toothed plate 14. When the drive gear 12 moves, it meshes with the toothed plate 14 and rotates, thereby driving the drive shaft 11 to rotate.

[0043] Please refer to Figures 3-6. Multiple sets of limiting cylinders 9 are movably installed inside the multiple sets of dewatering frames 6, and these limiting cylinders 9 are connected by synchronous belts. Each of the multiple limiting cylinders 9 is connected to a multiple set of drive shafts 11 by a synchronous belt. The outer walls of each of the multiple limiting shafts 10 have reciprocating threaded grooves, and the inner walls of each of the multiple limiting cylinders 9 have protrusions, which are threadedly connected to the inner walls of the reciprocating threaded grooves. When the drive shafts 11 rotate, they are connected to a set of limiting cylinders 9 via synchronous belts. When one set of limiting cylinders 9 rotates, the multiple sets of limiting cylinders 9 are connected by synchronous belts, and the multiple sets of limiting cylinders 9 rotate synchronously. The protrusions on the inner walls of the multiple sets of limiting cylinders 9 are movably connected to the inner walls of the reciprocating threaded grooves on the outer walls of the multiple sets of limiting shafts 10, causing the multiple sets of limiting shafts 10 to move, thereby driving the two sets of cleaning plates 8 to move back and forth.

[0044] The working principle of this utility model is as follows: When the operator uses the dewatering machine to dewater domestic sludge, the operator starts the hydraulic pump 2, which drives the hydraulic column 3 to move, thereby driving the pressure plate 4 to move. The pressure plate 4 presses the multiple sets of dewatering frames 6 together, and the multiple sets of dewatering frames 6 are tightly fitted together. Then the sludge pipe 21 transports the domestic sludge to the multiple sets of dewatering frames 6. The multiple sets of dewatering frames 6 remove the water from the domestic sludge, and then the water is discharged through the outlet pipe.

[0045] After the dewatering machine completes the dewatering of the domestic sewage sludge, the operator starts the hydraulic pump 2, which drives the hydraulic column 3 and the pressure plate 4 to reset. Then, the drive motor 16 is started, which drives a set of drive shafts 17 to rotate clockwise. The two sets of drive shafts 17 are connected by a synchronous belt, and they rotate synchronously. The outer walls of the two sets of drive shafts 17 are threadedly connected to the inner walls of the two sets of movable seats 18, so both sets of movable seats 18 are displaced. The two sets of push plates 19 are moved, and the two sets of movable seats 18 are moved towards the multiple sets of dehydration frames 6. The two sets of push plates 19 move to one side of the two sets of limiting plates 7. The two sets of limiting plates 7 block one end of the two sets of push plates 19, causing the two sets of push plates 19 to rotate. The two sets of push plates 19 rotate into the inner wall of the movable seat 18. Then the two sets of push plates 19 move to the other side of the two sets of limiting plates 7. The torsion spring at one end of the bearing inside the two sets of movable seats 18 drives the two sets of push plates 19 to reset.

[0046] After the two sets of push plates 19 are reset, the drive motor 16 drives the two sets of drive shafts 17 counterclockwise, and the two sets of movable seats 18 move towards the pressure plate 4, which in turn moves the two sets of push plates 19 towards the pressure plate 4. The two sets of push plates 19 are located on the other side of the two sets of limiting plates 7, pushing them to move, thereby moving a set of dehydration frames 6, which in turn moves a set of transmission gears 12. The transmission gears 12 mesh with the toothed plate 14, and when the transmission gears 12 rotate, the transmission shaft 11 rotates, and the transmission shaft 11 and a The sets of limiting cylinders 9 are connected by synchronous belts. One set of limiting cylinders 9 rotates, and multiple sets of limiting cylinders 9 are connected by synchronous belts. The multiple sets of limiting cylinders 9 rotate synchronously. The protrusions on the inner walls of the multiple sets of limiting cylinders 9 are movably connected to the inner walls of the reciprocating threaded grooves on the outer walls of the multiple sets of limiting shafts 10. The multiple sets of limiting shafts 10 are displaced, thereby driving the two sets of cleaning plates 8 to move back and forth. The two sets of cleaning plates 8 clean the inner walls on both sides of the dewatering frame 8, reducing the workload of the staff and improving the dewatering efficiency of sludge.
