Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water environment treatment, and particularly relates to a cleaning device for sludge in water environment treatment. BACKGROUND

[0002] Water environment treatment is a comprehensive and systematic project, which involves water resources, water environment, water ecology and other aspects, and in the environment of still water or slow flowing water, the water flow is not enough to carry heavy particulate matter to move, so that the particulate matter is deposited at the bottom of the water body,

[0003] The dredging equipment is generally arranged on a dredging ship, is carried by the dredging ship to move above the water body, and is used to pump out the sludge at the bottom of the water body during the movement to complete the river channel cleaning, but after the sludge is pumped out from the river channel by the existing dredging equipment, the sludge is stacked on the dredging ship or is transported to the shore through a pipeline, if the sludge is stacked on the ship, the water contained in the sludge greatly increases the weight of the sludge itself, so that the dredging ship needs to move back and forth to the shore to transfer the sludge, resulting in reduced dredging efficiency, and if the sludge is transported through the pipeline, the movement of the dredging ship is limited by the pipeline, so that the dredging ship cannot move flexibly.

At the same time, the dewatered sludge temporary storage mechanism can also be driven by a transmission gear ring.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0039] Please see the appendix Figures 1 to 9As shown, a sludge cleaning device for water environment treatment includes a sludge extraction mechanism 1. The sludge extraction mechanism 1 includes several sludge extraction pipes 11. A sludge discharge pipe 14 is provided on one side of the top of the sludge extraction pipe 11. A sludge extraction motor 12 is fixed to the top of the sludge extraction pipe 11. A screw conveyor 13 is fixed to the output end of the sludge extraction motor 12. The screw conveyor 13 is rotatably connected to the inside of the sludge extraction pipe 11. A sludge digging bucket 15 is fixed to the bottom of the sludge extraction pipe 11. One end of the sludge digging bucket 15 is set as an inclined surface.

[0040] The sludge dewatering mechanism 2 is located on one side of the sludge extraction mechanism 1. A water filtration mechanism 3 is provided on the outside of the sludge dewatering mechanism 2. A base 28 is installed at the bottom of the water filtration mechanism 3. The sludge dewatering mechanism 2 includes a feeding hopper 21 and several dewatering cylinders 23. A conveying pipe 22 is provided between the dewatering cylinders 23 and the feeding hopper 21. A dewatered sludge discharge pipe 24 is fixed at one end of the dewatering cylinder 23. A spiral dewatering component 26 is fixed at the output end of the dewatered sludge discharge pipe 24. The spiral dewatering component 26 is located inside the dewatering cylinder 23. A support 27 is provided on the conveying pipe 22. The other end of the spiral dewatering component 26 is rotatably connected to the support 27.

[0041] The dewatered sludge temporary storage mechanism 4 is located on one side of the sludge dewatering mechanism 2. The dewatered sludge temporary storage mechanism 4 includes a dewatered sludge temporary storage box 41. A reciprocating sliding flat mud plate 47 is provided above the dewatered sludge temporary storage box 41. A mud pushing plate 49 is provided on the upper surface of the middle part of the flat mud plate 47. A detachable sludge pressing mold 48 is installed at one end of the dewatered sludge temporary storage box 41.

[0042] The sludge briquetting mechanism 5 is installed at one end of the dewatered sludge temporary storage box 41. The sludge briquetting mechanism 5 includes an L-shaped support plate 51, which is fixed at one end of the dewatered sludge temporary storage box 41. A cylinder 52 is fixed at the top of the L-shaped support plate 51, and a briquetting mounting bracket 53 is fixed at the output end of the cylinder 52. A detachable extrusion block 54 is installed at the bottom of the briquetting mounting bracket 53. When the extrusion block 54 is controlled to descend, the extrusion block 54 will extrude the dewatered sludge in the sludge briquetting mold 48 to form sludge blocks.

[0043] The sludge block conveying mechanism 6 is located below the sludge briquetting mold 48 and is used to convey sludge blocks.

[0044] In the above, the sludge extraction mechanism 1 is set on the edge of the dredging vessel, so that the bottom of the sludge extraction mechanism 1 is inserted into the water body, and the sludge discharge pipe 14 is aligned with the feed hopper 21 of the sludge dewatering mechanism 2. The sludge extraction mechanism 1 is started while the dredging vessel moves, and the sludge scooping bucket 15 shovels the sludge at the bottom of the water body into the sludge scooping bucket 15. At the same time, the sludge pumping motor 12 drives the screw conveyor 13 to rotate, which can drive the sludge entering the sludge scooping bucket 15 to move upward along the sludge pumping pipe 11 and be transported through the sludge discharge pipe 14 to the feed hopper 21 to enter the sludge dewatering mechanism 2 for dewatering treatment.

[0045] The sludge entering the sludge dewatering mechanism 2 has a high water content. The sludge will enter the dewatering cylinder 23 along the conveying pipe 22. Under the action of the dewatering motor 25 driving the spiral dewatering component 26 to rotate, the sludge will move to the other end of the dewatering cylinder 23. At the same time, during the sludge conveying, the water in the sludge will be squeezed into the water filtration mechanism 3 installed on the outside of the sludge dewatering mechanism 2 for further filtration and discharge. The dewatered sludge will fall onto the dewatered sludge temporary storage box 41 through the dewatered sludge discharge pipe 24. The dewatered sludge on the dewatered sludge temporary storage box 41 will be spread flat by the reciprocating movement of the flat mud plate 47 and evenly spread into the sludge briquetting mold 48. The cylinder 52 drives the extrusion block 54 to descend and press into the sludge briquetting mold 48 to compact the dewatered sludge. By continuously spreading and compacting the dewatered sludge, it can be pressed into sludge blocks and transported out of the device through the sludge block conveying mechanism 6.

[0046] In a preferred embodiment, please refer again. Figure 6 The water filtration mechanism 3 includes a filter sleeve 31. Both the filter sleeve 31 and the dewatering cylinder 23 are provided with water filtration holes. A primary filter screen 32 is provided at the water filtration holes of the dewatering cylinder 23, and a secondary filter screen 33 is provided at the water filtration holes of the filter sleeve 31. An outer sleeve 34 is provided on the outside of the filter sleeve 31, and a drainage groove is provided at the bottom of the outer sleeve 34.

[0047] In this embodiment, the sludge is squeezed by the spiral dewatering component 26, so that the water in the sludge is filtered through the primary filter screen 32 into the filter sleeve 31, and then filtered again by the secondary filter screen 33 before entering the outer sleeve 34. The filtered water is then discharged into the water body through the drainage trough provided below the outer sleeve 34.

[0048] Secondly, please refer to the following as well. Figure 5 and Figure 6The filtration mechanism 3 also includes a rotating ring frame 35, which is rotatably connected to one end of the filter sleeve 31 and the outer sleeve 34. A plurality of first brush plates 36 and a plurality of second brush plates 37 are evenly installed on one side of the rotating ring frame 35. The first brush plates 36 are located between the dewatering cylinder 23 and the filter sleeve 31, and the second brush plates 37 are located between the filter sleeve 31 and the outer sleeve 34. A transmission gear ring 38 is fixed on the other side of the rotating ring frame 35. A transmission module 39 is fixed between two adjacent dewatering cylinders 23. The transmission module 39 includes a connecting plate. A cleaning motor is installed on one side of the connecting plate. A drive gear is fixed at the output end of the cleaning motor. The drive gear meshes with the transmission gear ring 38.

[0049] In the above, the cleaning motor can drive the drive gear to rotate. When the drive gear rotates, it can drive the transmission gear ring 38 connected to it to rotate. At the same time, the rotating ring frame 35 connected to the transmission gear ring 38 rotates. The first brush plate 36 and the second brush plate 37 fixed on one side of the rotating ring frame 35 can rotate between the dewatering cylinder 23 and the filter sleeve 31 and between the primary filter screen 32 and the outer sleeve 34, respectively. While rotating, they clean the primary filter screen 32 and the secondary filter screen 33 to avoid clogging.

[0050] For further details, please refer to the following: Figure 5 and Figure 6 Cleaning brushes are provided on both sides of the first brush plate 36, and a cleaning brush is provided on the side of the second brush plate 37 near the filter sleeve 31.

[0051] In this embodiment, when the rotating ring frame 35 drives the first brush plate 36 and the second brush plate 37 to rotate, the cleaning brushes located on both sides of the first brush plate 36 can clean the outer side of the primary filter screen 32 and the inner side of the secondary filter screen 33, while the brushes located on the inner side of the second brush plate 37 can clean the outer side of the secondary filter screen 33. This can effectively prevent the primary filter screen 32 and the secondary filter screen 33 from being blocked during the sludge dewatering process, thus avoiding a reduction in dewatering efficiency.

[0052] In a preferred embodiment, please also refer to Figure 1 , Figure 7 and Figure 8 A first mounting plate 42 is fixed to one end corner of the top side of the dewatered sludge storage box 41. A first transmission gear 43 and a second transmission gear 44 are installed on one side of the first mounting plate 42. The first transmission gear 43 and the second transmission gear 44 are meshed and connected. The first transmission gear 43 is meshed and connected to one of the transmission gear rings 38. A second mounting plate 45 is fixed to the other end corner of the top side of the dewatered sludge storage box 41. A reciprocating screw 46 is actively connected between the first mounting plate 42 and the second mounting plate 45. The reciprocating screw 46 is threadedly connected to the flat mud plate 47.

[0053] In this embodiment, when the transmission gear ring 38 rotates, it can drive the first transmission gear 43 and the second transmission gear 44 to rotate together. When the second transmission gear 44 rotates, it will drive the reciprocating screw 46 to rotate. When the reciprocating screw 46 rotates, it will drive the flat mud plate 47 to move back and forth in the dewatered sludge temporary storage box 41 under the action of the screw thread. When the flat mud plate 47 moves back and forth, the flat mud plate 47 and the push mud plate 49 can push the dewatered sludge on the dewatered sludge temporary storage box 41 to spread it evenly and spread the dewatered sludge into the sludge briquetting mold 48, which is convenient for subsequent sludge briquetting.

[0054] Secondly, please refer to again Figure 8 A sludge conveying chamber is provided at one end of the dewatered sludge storage box 41 and below the sludge briquetting mold 48. A sliding support plate 55 is provided between the sludge conveying chamber and the sludge briquetting mold 48. A drive motor 56 is fixed in the middle of the bottom of the dewatered sludge storage box 41. A drive screw 57 is fixed at the output end of the drive motor 56. The drive screw 57 is threadedly connected to the support plate 55.

[0055] As described above, when the sludge briquetting mechanism 5 presses the dewatered sludge, the support plate 55 located below the sludge briquetting mold 48 can seal the bottom of the sludge briquetting mold 48, so that the dewatered sludge is squeezed into blocks inside the sludge briquetting mold 48. After the sludge is briquetting, when the transmission screw 57 is rotated by the transmission motor 56, it can drive the support plate 55 to move horizontally under the action of the screw thread. When the support plate 55 moves to the point where it no longer seals the bottom of the sludge briquetting mold 48, the sludge blocks are then squeezed by the extrusion block 54. The sludge blocks can then fall through the sludge briquetting mold 48 into the sludge conveying chamber for transportation.

[0056] Secondly, please refer to the following as well. Figure 8 and Figure 9 The sludge block conveying mechanism 6 is installed in the sludge conveying chamber. The sludge block conveying mechanism 6 includes an active roller 64 and a driven roller 65. The active roller 64 and the driven roller 65 are rotatably installed at both ends of the sludge conveying chamber. A conveying motor 63 is fixed at one end of the active roller 64. A conveying track 61 is provided between the active roller 64 and the driven roller 65. A reinforcing plate 62 is provided between the active roller 64 and the driven roller 65 and inside the conveying track 61.

[0057] As described above, after the dewatered sludge is pressed into blocks and falls onto the surface of the conveyor belt 61, the drive roller 64 is rotated by the conveyor motor 63, which drives the conveyor belt 61 to move and transport the sludge blocks that fall on the conveyor belt 61 to one end of the conveyor belt 61 for storage.

[0058] The working principle of this invention is as follows: Silt from the water body is dredged into the dredging bucket 15, and the sludge is transported to the feed hopper 21 by the rotating screw conveyor 13 driven by the sludge pumping motor 12. The sludge then enters the dewatering cylinder 23 through the feed hopper 21. As the dewatering cylinder 23 drives the rotating screw dewatering component 26, it transports and compresses the sludge, causing the water in the sludge to be filtered out through the primary filter screen 32 on the dewatering cylinder 23. The dewatered sludge is then discharged into the dewatered sludge temporary storage box 41 through the dewatered sludge discharge pipe 24. Simultaneously, the transmission module 39 located at one end of the dewatered sludge discharge pipe 24 is activated, and the cleaning motor drives the drive gear to rotate. Under the meshing transmission, the drive gear ring 38 rotates, simultaneously driving the rotating ring frame 35 and the first brush. The first brush plate 36 and the second brush plate 37 rotate together. When the first brush plate 36 and the second brush plate 37 rotate, they can clean the primary filter screen 32 and the secondary filter screen 33 to avoid clogging and affect the dewatering effect. At the same time, the filtered water can be discharged into the water body from the drainage channel at the bottom of the outer sleeve 34. The dewatered sludge entering the dewatered sludge storage box 41 will drive the first mounting plate 42 and the first transmission gear 43 to rotate when the sludge briquetting mold 48 rotates, causing the reciprocating screw 46 to rotate and drive the flat mud plate 47 and the push mud plate 49 to reciprocate, so that the dewatered sludge is evenly spread on the dewatered sludge storage box 41 and evenly enters the sludge briquetting mold 48. After being pressed into sludge blocks by the sludge briquetting mechanism 5, it is transported out of the device by the sludge block conveying mechanism 6.

[0059] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
