Description

Technical Field

[0001] The present invention relates to the technical field of channel port silt removal, and more specifically, 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. Among them, mechanical silt removal requires the use of large-scale shovel excavation equipment, which is large in size and difficult to transport and has high cost. In addition, mechanical silt removal causes great 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 great risk of damaging the underwater ecological environment; suction silt removal is more commonly used, which causes less damage to the ecological environment, has low equipment requirements, and has a good silt removal effect.

The sucked-up sludge has a high water content, resulting in a heavy load on the ship. It is necessary to return to transfer the sludge to the shore to reduce the ship's 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, and an annular filter mesh body 94 is preferably arranged between the top of each separation cylinder 92 and the top surface of the purification barrel. When the water in the purification tank 93 located on the outside is full, it overflows to the adjacent purification tank 93 on the inside, so as to achieve the sedimentation and purification of the sludge and sewage; an annular first mud extraction channel is formed between the inner tube body and the outer tube body of the first sleeve 4, and an annular second mud extraction channel is formed between the inner tube body and the outer tube body of the second sleeve 5.

The free ends of the two output shafts 811 extend upward and downward respectively, pass through the corresponding accommodating chambers 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 first gear plate 832 is coaxially fixedly sleeved 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 with the corresponding accommodation cavity along the vertical direction through the slider 85, so 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, and a second gear plate 841 is coaxially fixedly sleeved on each sleeve 84, and each second gear plate 841 is meshed with the first gear plate 832, and 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; 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, it is achieved that the driving mechanism can selectively drive the rotating drum 1 to rotate and drive multiple anchor rods 61 to move in the vertical direction.
