Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-disc filter technology, and more specifically, to a slurry stripping device for a multi-disc filter. Background Technology
[0002] A disc filter is a device that uses vacuum suction to separate solids and liquids. It consists of multiple filter discs mounted on a horizontal hollow shaft. Vacuum filtration is achieved through negative pressure, with the negative pressure at the filtrate outlet serving as the driving force for filtration. Disc filters are widely used in the pulp and paper industry.
[0003] A search revealed a utility model patent with publication number CN220939526U, which discloses a novel slurry stripping device for a multi-disc filter. The device includes a main stripping pipe, which has several slurry stripping branch pipe assemblies arranged axially. Each branch pipe assembly includes a tee connector, a long branch pipe, a short branch pipe, and a stripping nozzle. The main stripping pipe connects to the tee connector, which connects to both the long and short branch pipes. Both the long and short branch pipes are connected to the stripping nozzle. This patent improves the slurry stripping device to adapt to different slurry thicknesses and speed ranges, thus improving overall machine performance and production efficiency under the same conditions. However, the aforementioned patent has the following shortcomings: although the angles of the long and short branch pipes can be adjusted, the adjustment range is limited, resulting in poor practicality. Therefore, we propose a slurry stripping device for a multi-disc filter. Utility Model Content

[0026] Please see Figure 1-5 A slurry stripping device for a multi-disc filter includes a slurry stripping main pipe 1. An installation collar 2 is fixedly sleeved on the outer side of the slurry stripping main pipe 1. A support frame 3 is fixedly connected to the side of the installation collar 2. A lifting mechanism 4 is provided on the support frame 3. Two lifting seats 5 are provided on the lifting mechanism 4. A first screw 6 is threaded onto one lifting seat 5. A first support 7 is rotatably connected to the end of the first screw 6. A first fixing ring 10 is fixedly connected to the side of the first support 7. A first slurry stripping nozzle 11 is fixedly sleeved on the first fixing ring 10. A first flexible hose 12 is fixedly connected to the top of the first slurry stripping nozzle 11. A second screw 8 is threaded onto the other lifting seat 5. A second support 9 is rotatably connected to the end of the second screw 8. A second fixing ring 13 is fixedly connected to the end of the second support 9. A second slurry stripping nozzle 14 is fixedly sleeved on the second fixing ring 13. A second flexible hose 15 is fixedly connected to the top of the second slurry stripping nozzle 14. The ends of both the second flexible hose 15 and the first flexible hose 12 are connected to the slurry stripping main pipe 1.
[0027] In this embodiment, the two lifting seats 5 are respectively provided with screw holes that are compatible with the first screw 6 and the second screw 8, so as to ensure that the threaded engagement between the lifting seat 5 and the first screw 6, and between the lifting seat 5 and the second screw 8 can drive the first support 7 and the second support 9 to move laterally. In addition, the first stripping nozzle 11 and the second stripping nozzle 14 are both switch-type, fan-shaped, backwashing type stripping nozzles, which realize the functions of adjustable water volume, increased stripping area, and backwashing of the stripping device.
[0028] For details, please refer to Figure 1 and Figure 2 The lifting mechanism 4 includes two lifting slots 18 opened on the upright frame 3. The inner cavity of each of the two lifting slots 18 is rotatably connected to a third screw 19. The two lifting seats 5 are respectively threaded onto the outside of the two third screws 19. The top ends of the two third screws 19 extend to the top of the upright frame 3 and are fixedly connected to a third knob 20.
[0029] In this embodiment, the lifting seat 5, the first support 7, the second support 9, the first stripping nozzle 11 and the second stripping nozzle 14 are moved up and down by the threaded engagement between the lifting seat 5 and the third screw 19, thereby adjusting the height of the first stripping nozzle 11 and the second stripping nozzle 14.
[0030] For details, please refer to Figure 2 The main stripping pipe 1 is provided with two internal threaded holes 16. The ends of the first hose 12 and the second hose 15 are fixedly connected with external threaded pipe plugs 17. The two external threaded pipe plugs 17 are respectively threaded into the inner cavity of the internal threaded holes 16.
[0031] In this embodiment, the first hose 12 and the second hose 15 are connected to the stripping main pipe 1 through the cooperation of the internal threaded hole 16 and the external threaded pipe plug 17.
[0032] For details, please refer to Figure 1 , Figure 3 and Figure 4 The first screw 6 is fixedly connected to the end of the first knob 22, and the first support 7 is fixedly connected to the side of the first slide rod 21. The first slide rod 21 and a lifting seat 5 are movably connected.
[0033] In this embodiment, the first screw 6 is rotated by the first knob 22, and the first support 7 is moved laterally by the threaded engagement between the first screw 6 and the lifting seat 5. In addition, the first support 7 is limited by the sleeve between the first slide rod 21 and the lifting seat 5, so that the first support 7 can only move along the axial direction of the first screw 6.
[0034] For details, please refer to Figure 1 , Figure 3 and Figure 5 The end of the second screw 8 is fixedly connected to the second knob 24, and the side of the second support 9 is fixedly connected to the second slide rod 23. The second slide rod 23 and another lifting seat 5 are movably connected.
[0035] In this embodiment, the second screw 8 is rotated by the second knob 24 so that the second support 9 can move laterally through the threaded engagement between the second screw 8 and the lifting seat 5. In addition, the second support 9 is limited by the sleeve between the second slide rod 23 and the lifting seat 5 so that the second support 9 can only move along the axial direction of the second screw 8.
[0036] For details, please refer to Figure 2 The side of the lifting seat 5 fits against the inner wall of the lifting groove 18.
[0037] In this embodiment, the inner wall of the lifting groove 18 is used to limit the lifting seat 5, so that the lifting seat 5 can only move along the axial direction of the third screw 19.
[0038] Working principle: In use, firstly, multiple mounting rings 2 and uprights 3 are fitted onto the outside of the stripping main pipe 1. The number of mounting rings 2 and the number of mounting rings 3 are equal to the number of discs in the multi-disc filter. Then, rotating two third knobs 20 drives two third screws 19 to rotate. Through the threaded engagement between the two third screws 19 and the two lifting seats 5, the lifting seats 5 move up and down, thereby adjusting the height of the first support 7, the second support 9, the first stripping nozzle 11, and the second stripping nozzle 14. Then, rotating the first knob 22 drives the first screw 6 to rotate. Through the threaded engagement between the first screw 6 and a lifting seat 5, the first support 7 and the first stripping nozzle 11 move laterally. The lateral position of the first stripping nozzle 11 is adjusted, and then the second knob 24 is turned to drive the second screw 8 to rotate. The threaded engagement between the second screw 8 and another lifting seat 5 drives the second support 9 to move laterally, thereby adjusting the lateral position of the second stripping nozzle 14. Finally, the slurry is conveyed in the stripping main pipe 1. The slurry enters the first stripping nozzle 11 through the internal threaded hole 16, the external threaded pipe plug 17, and the first hose 12. At the same time, the slurry enters the second stripping nozzle 14 through the internal threaded hole 16, the external threaded pipe plug 17, and the second hose 15. The slurry sprayed from the first stripping nozzle 11 and the second stripping nozzle 14 strips the slurry of the multi-disc filter.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
