Description

[0001] The invention relates to the technical field of sludge treatment, and in particular to a filter press dehydration device for sludge treatment. Background Art

[0002] When treating sludge, it is necessary to remove the moisture in the sludge. Generally, a filter press is used. During filtration, the material liquid to be filtered is sent into each filter chamber under the pressure of the feed pump, and the solid and liquid are separated through the filter medium, and the water is discharged. The sludge is dried in the filter chamber to form a filter cake. The thickness of the filter cake directly affects the filtration efficiency of the filter press and the quality of the filter cake.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

The first connecting pipe 16 and the second connecting pipe 17 are used to connect multiple filter chambers 27. The feed pump transports the sludge to each filter chamber 27. Under the action of the feed pump pressure, it is continuously squeezed, and the filter cloth plays a filtering role. The sludge is intercepted in the filter chamber 27, and the water is squeezed from the other side of the filter plate 19 and discharged from the outlet valve 6. After filtering, the two filter plates 19 move toward each other, which plays a secondary squeezing role on the formed filter cake, which is beneficial to ensure dehydration filtration. At the same time, when moving toward each other, it is beneficial to push the filter cake out of the connecting box 3, so that the filter cake can quickly leave the filter chamber 27, and the filter cake is quickly separated under the action of gravity.

[0030] Connecting ears 10 are fixedly connected on both sides of the multiple connecting boxes 3, and through holes are opened on the multiple connecting ears 10. Two sliding rods 2 are fixedly connected to the support frame 1, and the two sliding rods 2 pass through the through holes on both sides of the connecting box 3 respectively. The connecting box 3 is supported by the sliding rods 2 and the through holes.

[0031] A plurality of pairs of connection boxes 3 are connected to each other with a water outlet valve 6, a water collecting box 5 is fixedly connected to the support frame 1, the water collecting box 5 is located directly below the water outlet valve 6, a drainage pipe is connected to the water collecting box 5, and the water collecting box 5 plays a role in collecting water.

[0032] Two threaded columns 18 are fixedly connected to multiple filter plates 19, and threaded cylinders 15 are threadedly connected in the two threaded columns 18. The two threaded cylinders 15 are respectively fixedly connected to the connection box 3. A rack 13 is provided on the inner wall of the connection box 3. A through groove is provided on the connection box 3. The rack 13 passes through the through groove and abuts against the inner wall of the through groove. A first gear 14 is fixedly connected to the two threaded cylinders 15. The two first gears 14 are respectively meshed with the rack 13. The rack 13 moves to drive the first gear 14 to rotate, thereby adjusting the position of the threaded column 18 in the threaded cylinder 15, driving the filter plate 19 to move, so that the two filter plates 19 in each pair of connection boxes 3 move away from each other or towards each other, adjusting the thickness of the filter chamber 27, and thus adjusting the thickness of the formed filter cake, so as to dehydrate sludge according to different concentrations and particle sizes, thereby ensuring the dehydration filtration efficiency and the quality of the filter cake, and improving the adaptability of the device.

[0033] Multiple racks 13 are fixedly connected with sliding sleeves 9, and multiple sliding sleeves 9 are sleeved on the connecting plate 8. The two ends of the connecting plate 8 move through the telescopic mechanism. When the connecting box 3 moves horizontally, the connecting box 3 drives the racks 13 to move, which will drive the sliding sleeves 9 to slide on the connecting plate 8.

[0034] A hydraulic cylinder 7 is fixedly connected to the support frame 1, and the hydraulic cylinder 7 is fixedly connected to the connection box 3. The outermost connection box 3 at the other end is fixedly connected to the support frame 1. A mud inlet pipe is connected to the connection box 3, and the mud inlet pipe is connected to the feed pump.

[0035] The telescopic mechanism includes a rotating cylinder 34, the internal thread of the rotating cylinder 34 is connected to a threaded rod 11, the threaded rod 11 is fixedly connected to the connecting plate 8, the rotating cylinder 34 is rotatably connected to the support frame 1 through a bearing, the rotating cylinder 34 is driven by a driving mechanism, and the driving mechanism drives the rotating cylinder 34 to rotate, thereby adjusting the position of the threaded rod 11 in the rotating cylinder 34, thereby driving the connecting plate 8 to move, so that the multiple racks 13 move, thereby driving the filter plate 19 to move.

[0036] Embodiment 2: In embodiment 1, when the filter cake is taken out, the filter plate 19 is moved to push the filter cake out of the filter chamber 27, thereby achieving a detachment effect. When the filter plate 19 is reset, a driving mechanism is required to drive the connecting plate 8 to move so that the height of the connecting plate 8 is reset. Since the driving mechanism is generally driven by a motor, it is necessary to ensure that the connecting plate 8 returns to its initial position when resetting. After the filter cake is squeezed out and reset, the filter plate 19 returns to its initial position so that the thickness of the filter chamber 27 does not change. However, it is difficult to control the number of revolutions of the motor, so that when the filter plate 19 is reset, the filter plate 19 moves too much or too little, resulting in a slight deviation in the position of the filter plate 19, which results in a change in the thickness of the filter chamber 27 when the sludge of the same concentration and particle size is pressure filtered, and the thickness of the filter cake changes, which affects the filtration efficiency and the quality of the filter cake. Figure 1-9 , as another preferred embodiment of the present invention, based on Example 1.

[0037] The driving mechanism includes a motor 12, which is mounted on the support frame 1. A connecting disk 31 is drivingly connected to the output shaft of the motor 12. A plurality of rotating blocks 30 are connected to the connecting disk 31 for equidistant rotation. A connecting portion 25 is fixedly connected to each of the plurality of rotating blocks 30. A plurality of first blocks 35 are fixedly connected to the connecting disk 31. The first blocks 35 are magnets, and the rotating blocks 30 are iron blocks, so that the rotating blocks 30 can be reset by attraction. The plurality of first blocks 35 are respectively abutted against one side of the corresponding rotating blocks 30. The other sides of the plurality of rotating blocks 30 are provided with second blocks 36 abutted against each other. The plurality of second blocks 36 are positioned by a positioning mechanism. The plurality of second blocks 36 are hinged with hinged rods 28, and the plurality of hinged rods 28 are hinged with movable disks. 32, the movable disk 32 is rotatably connected to the rotating disk 21 through a bearing, the movable disk 32 is limited by a limiting mechanism, a pulling block 26 is arranged below the rotating disk 21, a connecting rod 24 is fixedly connected to the pulling block 26, a connecting cylinder 22 is sleeved on the connecting rod 24, the connecting cylinder 22 is fixedly connected to the connecting plate 8, a bolt 23 is threadedly connected to the connecting cylinder 22, the bolt 23 abuts against the connecting rod 24, a second gear 20 is fixedly connected to the rotating cylinder 34, a plurality of connecting parts 25 are located in the gear groove of the second gear 20, the motor 12 is rotated to make the connecting plate 8 move downward, the rack 13 drives the first gear 14 to rotate, so that the two filter plates 19 move toward each other, and the filter cake is squeezed and pushed out. Fig. 9 As shown, the motor 12 rotates counterclockwise to drive the connecting plate 31 to rotate. Due to the obstruction of the first stopper 35, the connecting portion 25 will not rotate, so that the connecting portion 25 will drive the second gear 20 to rotate, thereby driving the rotating cylinder 34 to rotate, and squeezing and pushing the filter cake. After the end, when the motor 12 is controlled to rotate clockwise, the connecting plate 8 will move upward, driving the pulling block 26 to move upward, and the filter cake will be squeezed. Fig. 9In the position shown, the pulling block 26 abuts against the rotating disk 21, so that the rotating disk 21 moves upward, driving the upper end of the hinged rod 28 to move upward, so that the lower end of the hinged rod 28 drives the second stopper 36 to move, so that the second stopper 36 releases the limit on the rotating block 30. When the connecting disk 31 rotates, the connecting portion 25 is movable and can rotate around the rotating axis of the rotating block 30, thereby failing to drive the second gear 20 to rotate, so that the position of the filter plate 19 is fixed. After reaching the initial position, it will not move, thereby ensuring that when the sludge of the same concentration and particle size is filtered, the thickness of the filter chamber 27 will not change, so that the thickness of the filter cake will not change, and when the sludge of another concentration and particle size is replaced During mud filtering, by adjusting the position of the connecting rod 24 in the connecting tube 22, the bolt 23 is tightened and fixed, and the motor 12 rotates clockwise to drive the pulling block 26 to move upward. The time for the second stopper 36 to release the limit on the connecting part 25 is controlled, so that after the thickness of the filter chamber 27 is adjusted, the filter plate 19 can stop when it reaches the initial position, ensuring that the thickness of the filter chamber 27 is fixed during use. When the driving motor 12 rotates counterclockwise and drives the connecting plate 8 to move downward, the pulling block 26 will move downward. Under the action of the spring recovery, the rotating disk 21 is driven to move downward and reset, so that the lower end of the hinged rod 28 pushes the second stopper 36 to move, and the second stopper 36 again limits and fixes the rotating block 30.

[0038] The positioning mechanism includes a limiting sleeve 33 , which is fixedly connected to the connecting plate 31 . The limiting sleeve 33 is sleeved on the second stopper 36 , and the limiting sleeve 33 has a limiting function for the second stopper 36 .

[0039] The limiting mechanism includes a limiting column 29, which is fixedly connected to the connecting disk 31. The limiting column 29 passes through the movable disk 32. A spring is fixedly connected between the movable disk 32 and the connecting disk 31. The spring is used to reset the position of the movable disk 32. The limiting column 29 limits the connecting disk 31 to prevent the connecting disk 31 from deviating.

[0040] Example 3: Reference Figure 1-9 As another preferred embodiment of the present invention, on the basis of Embodiment 2, a connecting rope 4 is connected between each two adjacent connecting boxes 3. By adopting the connecting rope 4, when the hydraulic cylinder 7 contracts, under the action of the connecting rope 4, the multiple connecting plates 8 are pulled to open the filter chamber 27 so as to push out the filter cake.

[0041] When in use; Figure 1-9 The hydraulic cylinder 7 is in the initial position, and the hydraulic cylinder 7 is extended to squeeze the multiple connection boxes 3 together. Then the feed pump conveys the sludge to each filter chamber 27. Under the action of the feed pump pressure, the sludge is continuously squeezed, and the filter cloth plays a filtering role. The sludge is intercepted in the filter chamber 27, and the water is squeezed from the filter plate 19 through the filter cloth and discharged from the water outlet valve 6;

[0042] After the end, the motor 12 rotates counterclockwise to drive the connecting plate 31 to rotate. Due to the obstruction of the first stopper 35, the connecting part 25 is fixed, so that the connecting part 25 will drive the second gear 20 to rotate, drive the rotating cylinder 34 to rotate, and the threaded rod 11 moves downward. The position of the threaded rod 11 in the rotating cylinder 34 is adjusted, thereby driving the connecting plate 8 to move, so that the multiple racks 13 move, driving the first gear 14 to rotate, thereby adjusting the position of the threaded column 18 in the threaded cylinder 15, and driving the filter plate 19 to move, so that the two filter plates 19 move toward each other, and the filter cake is squeezed for secondary dehydration. Then the hydraulic cylinder 7 contracts, and the multiple connecting boxes 3 are pulled and unfolded. The continuous movement of the filter plate 19 will push the filter cake out of the filter chamber 27;

[0043] Finally, when the motor 12 is controlled to rotate clockwise, the rotating cylinder 34 is driven to rotate, the threaded rod 11 moves upward, the filter plate 19 is reset, and the connecting plate 8 moves upward, driving the pulling block 26 to move upward. When the pulling block 26 abuts against the rotating disk 21, the rotating disk 21 moves upward, driving the upper end of the hinged rod 28 to move upward, so that the lower end of the hinged rod 28 drives the second stopper 36 to move, so that the second stopper 36 releases the limit on the rotating block 30. When the connecting disk 31 rotates, the connecting part 25 can rotate, and the second gear 20 cannot be driven to rotate, so that the filter plate 19 cannot move, so that the filter plate 19 can accurately return to its initial position.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
