Description

Technical Field

[0001] This utility model relates to the technical field of sludge dewatering mechanisms, and in particular to a sludge dewatering mechanism for waterway dredging. Background Technology

[0002] With the continuous development of ports and shipping, dredging of ports and waterways has become essential to ensure the normal passage of ships and the protection of the aquatic environment. Waterway dredging refers to the removal of silt, weeds, and debris from waterways to ensure the safe passage of ships. During the dredging process, silt is generally handled in two ways: either it is piled up on the shore for transfer, or it is stored on the dredging vessel. However, during silt dredging, liquid from the silt is also stored on the vessel, and silt on the shore flows downstream with the liquid. The lack of a mechanism for dewatering and separating the silt during dredging affects the efficiency of silt transfer and dredging.

[0003] In the existing technology patent CN221720683U, a channel dredging sludge dewatering mechanism is disclosed. During the vertical extraction process driven by the drive motor to drive the spiral blades, the sludge is transported obliquely or vertically along the suction pipe, and the sludge is directly separated and dewatered through the recovery sludge box. This avoids the excessive amount of liquid stored during the sludge extraction process, which would increase the difficulty of sludge extraction and reduce the extraction efficiency. By setting a hemispherical filter screen and filter plate, impurities or stones inside the sludge are extracted into the equipment, which would cause blockage of the equipment's drainage section.

[0004] In the existing methods described above, different lengths of suction pipes are required for different channel depths. The installation and dismantling of the suction pipes require a lot of manpower and time, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a channel dredging sludge dewatering mechanism, which solves the problem in the prior art that different lengths of suction pipes need to be replaced when the channel is at different depths, and the installation and disassembly of the suction pipes require a lot of manpower and time, resulting in low work efficiency.

[0006] To achieve the above objectives, this utility model employs a channel dredging sludge dewatering mechanism, comprising a sludge recovery box, a mixing assembly, a filter screen, a suction pipe, a slurry conveying assembly, a corrugated telescopic pipe, a hemispherical filter screen, a fixing sleeve, and two sets of pushing assemblies. The mixing assembly is disposed within the sludge recovery box, and the suction pipe is connected to the mixing assembly. The slurry conveying assembly is disposed within the sludge recovery box, and the suction pipe is connected to the slurry conveying assembly. The filter screen is fixedly connected to the suction pipe and located within the suction pipe. The corrugated telescopic pipe is fixedly connected to the suction pipe, and the hemispherical filter screen is fixedly connected to the corrugated telescopic pipe and located at the bottom of the corrugated telescopic pipe. The fixing sleeve is fixedly fitted onto the outer wall of the corrugated telescopic pipe. Each set of pushing assemblies is respectively connected to the sludge recovery box and the fixing sleeve.

[0007] The pushing component includes a mounting frame, a threaded rod, a sleeve, and a movable rod. The mounting frame is fixedly connected to the recycling mud box and located below the recycling mud box. Both ends of the threaded rod are rotatably connected to the mounting frame. The sleeve is sleeved on the outside of the threaded rod and threadedly engaged with the threaded rod. Both ends of the movable rod are rotatably connected to the sleeve and the fixed sleeve, respectively.

[0008] The waterway dredging sludge dewatering mechanism also includes two connecting rods and a guide sleeve. The guide sleeve is movably sleeved on the outside of the corrugated telescopic pipe, and the two ends of each connecting rod are fixedly connected to the guide sleeve and the fixed sleeve, respectively.

[0009] The channel dredging sludge dewatering mechanism also includes two force-applying rods, both of which are fixedly connected to the recovery sludge box and are located on the outer wall of the recovery sludge box.

[0010] The mixing assembly includes a mixing disc, a mixing rod, and a drive rod. The drive rod is rotatably connected to the recycled sludge box and is located inside the recycled sludge box. The mixing disc is fixedly connected to the drive rod, and the mixing rod is fixedly connected to the mixing disc and is located below the mixing disc.

[0011] The slurry delivery assembly includes a movable seat and a mud pump. The movable seat is rotatably connected to the mixing disc and is located below the mixing disc. The mud pump is fixedly connected to the movable seat and is located inside the movable seat. The suction pipe is connected to the input end of the mud pump.

[0012] This utility model discloses a channel dredging sludge dewatering mechanism. In use, the recovery sludge box is first fixed to the vessel. Then, the length of the corrugated telescopic tube on the suction pipe is adjusted according to the channel depth. Simultaneously, the threaded rods within the two mounting frames are driven to rotate. The two sleeves then extend the movable rods, which push the fixed sleeves downwards, further extending the corrugated telescopic tube and increasing the suction length. When the current channel depth is suitable, the threaded rods are stopped, and the corrugated telescopic tube no longer extends or retracts. The sludge is then extracted from the channel using the sludge conveying assembly. The sludge is continuously sucked into the recovery sludge box and filtered. The screen filters the sludge, and the liquid is discharged directly into the recovery sludge tank through the drain pipe at the bottom, completing the sludge dewatering process. Simultaneously, the operator continuously mixes the sucked-in sludge using the mixing component, accelerating the discharge of liquid from the sludge and preventing the sludge from directly sealing the top of the filter screen. The hemispherical filter screen blocks and filters stones in the sludge, preventing them from directly clogging the suction pipe and the recovery sludge tank during suction. This method allows for adjustment of the suction pipe length according to the channel depth without disassembling or replacing it, significantly reducing manpower and time and improving work efficiency.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-4 This utility model provides a channel dredging sludge dewatering mechanism, comprising a sludge recovery tank 101, a mixing assembly, a filter screen 102, a sludge suction pipe 103, a slurry conveying assembly, a corrugated telescopic pipe 104, a hemispherical filter screen 105, a fixing sleeve 106, and two sets of pushing assemblies. The mixing assembly is disposed within the sludge recovery tank 101, and the sludge suction pipe 103 is connected to the mixing assembly. The slurry conveying assembly is disposed within the sludge recovery tank 101, and the sludge suction pipe 103 is connected to the slurry conveying assembly. The filter screen 102 is fixedly connected to the sludge suction pipe 103 and is located inside the sludge suction pipe 103. The corrugated telescopic pipe 104 is fixedly connected to the sludge suction pipe 103. The hemispherical filter screen 105 is fixedly connected to the corrugated telescopic pipe 104 and is located at the bottom of the corrugated telescopic pipe 104. The fixing sleeve 106 is provided on the outer wall of the corrugated telescopic pipe 104. Each set of the pushing components is respectively connected to the sludge recycling box 101 and the fixing sleeve 106.

[0021] The pushing component includes a mounting frame 107, a threaded rod 108, a sleeve 109, and a movable rod 110. The mounting frame 107 is fixedly connected to the recycling mud box 101 and is located below the recycling mud box 101. Both ends of the threaded rod 108 are rotatably connected to the mounting frame 107. The sleeve 109 is sleeved on the outside of the threaded rod 108 and threadedly engaged with the threaded rod 108. Both ends of the movable rod 110 are rotatably connected to the sleeve 109 and the fixed sleeve 106, respectively.

[0022] In this embodiment, during use, the recovery mud box 101 is first fixed to the ship. Then, the length of the corrugated telescopic tube 104 on the suction pipe 103 is adjusted according to the channel depth. Simultaneously, the second motors on the outer sides of the two mounting frames 107 are started, and the threaded rod 108 rotates within the mounting frame 107. The two sleeves 109 respectively drive the movable rod 110 to extend. At the same time, the movable rod 110 pushes the fixed sleeve 106 downward, causing the corrugated telescopic tube 104 to be stretched, resulting in an increase in the suction length. When it adapts to the current channel depth, the rotation of the threaded rod 108 is stopped, and the corrugated telescopic tube 104 no longer extends or retracts. Then, the slurry conveying assembly is used to extract the silt in the channel, and the silt is continuously sucked into the recovery mud box 101. Inside the sludge tank 101, the sludge is filtered through the filter screen 102, and the liquid is discharged directly out of the tank through the drain pipe at the bottom, thus completing the sludge dewatering process. Simultaneously, the operator continuously mixes the sucked-in sludge using the mixing assembly, accelerating the discharge of liquid from the sludge and preventing the sludge from directly sealing the top of the filter screen 102. The hemispherical filter screen 105 blocks and filters stones in the sludge, preventing stones from directly clogging the suction pipe 103 and the inside of the sludge tank 101 during the suction process. This method allows for adjustment of the length of the suction pipe 103 according to the channel depth, eliminating the need to disassemble and replace the suction pipe 103, significantly reducing manpower and time, and improving work efficiency.

[0023] Furthermore, the channel dredging sludge dewatering mechanism also includes two connecting rods 111 and a guide sleeve 112. The guide sleeve 112 is movably sleeved on the outside of the corrugated telescopic tube 104, and the two ends of each connecting rod 111 are fixedly connected to the guide sleeve 112 and the fixed sleeve 106, respectively.

[0024] In this embodiment, by setting the connecting rod 111 and the guide sleeve 112, the guide sleeve 112 will move with the fixed sleeve 106. The guide sleeve 112 guides the corrugated telescopic tube 104, which facilitates the extension and retraction of the corrugated telescopic tube 104 and avoids the bending of the wires of the corrugated telescopic tube 104.

[0025] Furthermore, the channel dredging sludge dewatering mechanism also includes two force-applying rods 113, both of which are fixedly connected to the recovery sludge box 101 and are located on the outer side wall of the recovery sludge box 101.

[0026] In this embodiment, by providing the force-applying rods 113 on both sides of the recycling mud box 101, the recycling mud box 101 can be easily moved using the force-applying rods 113, making the operation convenient.

[0027] Furthermore, the mixing assembly includes a mixing disc 114, a mixing rod 115, and a drive rod 116. The drive rod 116 is rotatably connected to the recycled sludge box 101 and is located inside the recycled sludge box 101. The mixing disc 114 is fixedly connected to the drive rod 116, and the mixing rod 115 is fixedly connected to the mixing disc 114 and is located below the mixing disc 114.

[0028] In this embodiment, by starting the second motor 120, the second motor 120 controls the mixing disc 114 to rotate, and then the mixing rod 115 at the bottom of the mixing disc 114 rotates. The mixing rod 115 continuously mixes the sucked sludge, and the centrifugal rotation applies acceleration to accelerate the discharge process of pore water, so that the equipment has a high efficiency in sludge dewatering and solidification, and can quickly process sludge on site.

[0029] Furthermore, the slurry delivery assembly includes a movable seat 118 and a mud pump 117. The movable seat 118 is rotatably connected to the mixing disc 114 and is located below the mixing disc 114. The mud pump 117 is fixedly connected to the movable seat 118 and is located inside the movable seat 118. The suction pipe 103 is connected to the input end of the mud pump 117.

[0030] In this embodiment, the sludge pump 117 drives the corrugated expansion pipe 104 to extract sludge from the waterway. The sludge enters the recovery sludge box 101 through the corrugated expansion pipe 104 and is directly separated and dehydrated. Impurities or stones inside the sludge are extracted into the equipment by the hemispherical filter screen 105 and the filter screen plate 102, causing blockage in the equipment's drainage section.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
