Description

Technical Field

[0001] The present invention relates to the technical field of waterway and port silt removal, and more particularly to a port silt treatment device and a treatment method thereof. Background Art

[0002] Port silt needs to be cleaned regularly to ensure smooth and safe navigation of ships in the waterway. Common silt cleaning methods include mechanical silt removal, blasting silt removal, and suction silt removal. Mechanical silt removal requires the use of large-scale shovel-excavating equipment, which is bulky and difficult to transport and has high construction costs. In addition, mechanical silt removal causes significant damage to the underwater ecological environment. Blasting silt removal uses blasting technology to break up silt, which has great blasting power and causes large-scale water pollution. It also poses a significant risk to the underwater ecological environment. Suction silt removal is the most commonly used method, which causes less damage to the ecological environment, requires less equipment, and has a good silt removal effect.

[0003] Most of the existing suction dredging equipment are unable to deal with the accumulated water in the silt in a timely manner. The sucked-up silt has a high water content, which causes a heavy load on the ship. The ship needs to return to transfer the silt to the shore to reduce the load, and then sail to the dredging site again. A dredging operation requires the ship to make multiple round trips, which greatly reduces the efficiency of the dredging operation. Summary of the Invention

The bottom surface of the barrel 91 is sealed and connected. An annular filter mesh body 94 is preferably provided between the top of each separation cylinder 92 and the top surface of the purification barrel. When the water in the purification pool 93 on the outside is full, it overflows to the adjacent purification pool 93 on the inside, thereby achieving the sedimentation and purification of the sludge and sewage. An annular first mud pumping channel is formed between the inner and outer tube bodies of the first sleeve 4, and an annular second mud pumping channel is formed between the inner and outer tube bodies of the second sleeve 5.

The mud pump 25 and the high-pressure water pump 35 can similarly adopt existing technical means. By providing a connecting piece, the mud pump 25 and the high-pressure water pump 35 are connected to the outer wall of the purification barrel 91. The water delivery direction of the high-pressure water pump 35 is to deliver the water from the innermost purification pool 93 to the water delivery pipe 34;The lower circumferential side surface of the second sleeve 5 is rotatably connected to the top surface of the drum 1, and the bottom of the second sleeve 5 is sealed and rotatably connected to the bottom of the first sleeve 4 (to ensure that the rotation of the drum 1 drives the mud pumping mechanism and the water spraying mechanism to rotate around the axis of the drum 1 without affecting the normal transportation of sludge and filtered water). The first mud pumping channel is connected to the second mud pumping channel to form a sludge transportation channel, and the first water transportation channel is connected to the second water transportation channel to form a water transportation channel. The transportation channel is connected to the outermost purification tank 93 through the mud transportation pipe 24.

The water spraying mechanism sprays the water separated from the sludge back to the bottom of the water, and uses the impact force of the sprayed water to crush and disperse the sludge.

[0057] The port sludge treatment device provided by the present invention can efficiently pump out the sludge while separating the accumulated water in the sludge in a timely manner, and recover the separated filtered water to the bottom of the water. At the same time, the impact force of the recovered water flow is used to break up the sludge, thereby reducing the load of the ship, reducing the number of round trips of the ship during the sludge treatment process, and improving the efficiency of the dredging operation.

[0058] The port sludge treatment device provided by the present invention is placed on a ship during navigation or port dredging. The ship sails in the channel or port to the area to be dredged, and the drum 1 is lowered to the bottom of the water by a winch. The mud pumping mechanism and the water spraying mechanism are lowered to the bottom of the water along with the drum 1. The sealing of each pipeline is checked, and then the driving mechanism is started to drive the drum 1 to rotate around its own axis, thereby driving the mud pumping mechanism and the water spraying mechanism to rotate around the axis of the drum 1. Subsequently, the mud pump 25 is started to drive the mud pumping mechanism to suck the sludge.

The water is then transported to the water spray mechanism through the water pipe 34 and the water delivery pipeline, and is sprayed to the bottom of the water by the water spray mechanism.

[0075] In the above technical solution, the present invention further discloses a specific structure of a driving mechanism for driving the drum 1 to rotate and also for driving the anchor rods 61 to move up and down. The driving mechanism includes a dual-axis motor 81 arranged inside the counterweight 6, a first rotating shaft 82 coaxially fixed to the bottom of the drum 1, a second rotating shaft 83 coaxially arranged inside the counterweight 6, a sleeve 84 corresponding to a plurality of anchor rods 61, and a plurality of sliders 85 for connecting the anchor rods 61 and the counterweight 6 in a vertical direction. Preferably, the slider 85 is arranged on the counterweight 6. A plurality of accommodating cavities are provided in the weight block 6 for arranging the dual-axis motor 81, the second rotating shaft 83 and the plurality of sleeves 84. The corresponding accommodating cavities are communicated with each other so that the various components are connected in a coordinated manner. The two output shafts 811 of the dual-axis motor 81 rotate coaxially with the rotating drum 1 and are arranged in the corresponding accommodating cavities. The free ends of the two output shafts 811 extend upward and downward respectively, pass through the corresponding accommodating cavities and are both provided with iron blocks 812. The first rotating shaft 82 is coaxially arranged with the rotating drum 1 and the upper end of the first rotating shaft 82 is connected to the rotating drum 1. The bottom of the cylinder 1 is fixed, and the lower end is provided with a first electromagnet 821 in contact with the upper iron block 812. The second rotating shaft 83 is coaxially arranged in the counterweight block 6 and is located below the dual-axis motor 81. The upper end of the second rotating shaft 83 is provided with a second electromagnet 831 in contact with the lower iron block 812, and the lower end is rotatably connected to the bottom of the corresponding accommodating cavity. The first gear plate 832 is coaxially fixed on the second rotating shaft 83; a sleeve 84 is rotatably sleeved on the upper thread of each anchor rod 61, and each sleeve 84 is rotatably connected to the corresponding accommodating cavity. Then, each anchor rod 61 is slidably connected to the corresponding accommodating cavity in the vertical direction through the slider 85. Therefore, the rotation of the sleeve 84 around its own axis can drive the corresponding anchor rod 61 to move in the vertical direction relative to the counterweight block 6. A second gear plate 841 is coaxially fixedly sleeved on each sleeve 84. Each second gear plate 841 is engaged with the first gear plate 832. Then, all the sleeves 84 can be driven to rotate by rotating the second rotating shaft 83, thereby driving all the anchor rods 61 to move in the vertical direction relative to the counterweight block 6.

[0076] If the first electromagnet 821 is energized, the upper output shaft 811 and the lower end of the first rotating shaft 82 are connected by the magnetic attraction of the first electromagnet 821 and the upper iron block 812. Starting the dual-axis motor 81 can drive the first rotating shaft 82 to rotate around its own axis, and then drive the rotating drum 1 to rotate around its own axis. If the second electromagnet 831 is energized, the lower output shaft 811 and the upper end of the second rotating shaft 83 are connected by the magnetic attraction of the second electromagnet 831 and the lower iron block 812. Starting the dual-axis motor 81 can drive the second rotating shaft 83 to rotate around its own axis, and then drive multiple sleeves 84 to rotate, thereby driving multiple anchor rods 61 to move in the vertical direction relative to the counterweight block 6. By setting the dual-axis motor 81, the first electromagnet 821, the second electromagnet 831, and the two iron blocks 812, the driving mechanism can selectively drive the rotating drum 1 to rotate and drive multiple anchor rods 61 to move in the vertical direction.

[0078] S1. Place the port sludge treatment device on a vessel, and move the vessel to the location of the sludge to be treated within the port or waterway; then lower the drum 1 to the bottom of the water by a winch;

[0079] S2. Start the driving mechanism to drive the drum 1 to rotate around its own axis; then start the sludge pump 25, sucking the sludge through the sludge pumping mechanism and transporting the sludge to the outermost purification tank 93 through the first sleeve 4, the second sleeve 5 and the sludge pipe 24; in any purification tank 93, the sludge settles in the purification tank 93, and the upper layer of water overflows into the adjacent purification tank 93;

[0080] S3. When the water level of the innermost purification tank 93 reaches a preset height, the high-pressure water pump 35 is started to spray high-pressure water through the water spray mechanism to transport the multi-stage purified water in the innermost purification tank 93 back to the port or the sea.
