Description

Port sludge treatment equipment and treatment methods Technical Field

[0001] This invention relates to the field of waterway and port dredging technology. More specifically, this invention relates to a port silt treatment device and method. Background Technology

[0002] Port silt needs to be cleaned regularly to ensure smooth and safe navigation for ships in the waterway. Common silt removal methods include mechanical dredging, blasting dredging, and suction dredging. Mechanical dredging requires large excavating equipment, which is bulky, difficult to transport, and expensive. In addition, mechanical dredging causes significant damage to the underwater ecosystem. Blasting dredging uses blasting technology to break up the silt, but the powerful blasts cause widespread water pollution and also pose a significant threat to the underwater ecosystem. Suction dredging is more commonly used because it causes less damage to the ecosystem, requires less equipment, and has good silt removal results.

[0003] Existing dredging equipment often fails to remove water from the silt in a timely manner. The silt pumped up has a high water content, resulting in a heavy load on the ship. The ship needs to return to shore to transfer the silt to reduce the load before sailing back to the dredging site. A single dredging operation requires the ship to make multiple round trips, which greatly reduces the efficiency of the dredging operation. Summary of the Invention

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] As shown in Figures 1-6, the present invention provides a port silt treatment device, which includes:

[0048] Rotating cylinder 1 is a vertically arranged, hollow cylindrical structure; the rotating cylinder 1 rotates around its own axis under the drive of the driving mechanism;

[0049] Multiple sludge pumping mechanisms are arranged circumferentially around the outer periphery of the rotating drum 1;

[0050] Multiple water spraying mechanisms are arranged circumferentially around the outer periphery of the rotating drum 1, and each water spraying mechanism and each sludge pumping mechanism do not interfere with each other.

[0051] The sludge purification mechanism includes a vertically arranged, hollow cylindrical purification tank 91 and a plurality of partition cylinders 92 coaxially sleeved inside the purification tank 91. The partition cylinders 92 divide the purification tank 91 into a plurality of purification pools 93 radially from the inside to the outside, and the height of the partition cylinders 92 increases radially from the inside to the outside, with the height of the outermost partition cylinder 92 being less than the height of the purification tank.

[0052] The first sleeve 4 is a double-layered tube coaxially disposed inside the rotating drum 1. The mud outlet of each mud pumping mechanism is connected to the lower end of the outer tube of the first sleeve 4, and the water inlet of each water spraying mechanism is connected to the lower end of the inner tube of the first sleeve 4; (the top of the first sleeve 4 is flush with the top surface of the rotating drum 1).

[0053] The second sleeve 5 is a double-layered tube body coaxially arranged with the first sleeve 4. The lower end of the outer tube body of the second sleeve 5 is sealed and rotatably connected with the upper end of the outer tube body of the first sleeve 4, and the lower end of the inner tube body of the second sleeve 5 is sealed and rotatably connected with the upper end of the inner tube body of the first sleeve 4 (the second sleeve 5 is rotatably connected to the top surface of the rotating cylinder 1).

[0054] The mud conveying pipe 24 has one end connected to the upper end of the outer pipe of the second sleeve 5 and the other end connected to the outermost purification tank 93; the mud conveying pipe 24 is equipped with a mud pump 25.

[0055] The water supply pipe 34 has one end connected to the upper end of the inner tube of the second sleeve, and the other end connected to the water outlet at the bottom of the innermost purification tank 93. A filter screen is connected inside the water outlet. A high-pressure water pump 35 is installed on the water supply pipe 34.

[0056] In the above technical solution, the present invention provides a port silt treatment device, which can be used to remove silt deposited at the bottom of port water. The port silt treatment device includes a vertically arranged rotating drum 1, with multiple sludge suction mechanisms and multiple water spraying mechanisms arranged around the rotating drum 1. The sludge suction mechanisms are used to suck silt from the bottom of the water, and the water spraying mechanisms are used to spray water into the silt at the bottom of the water. The impact force of the sprayed water is used to crush and disperse the silt. The multiple sludge suction mechanisms and multiple water spraying mechanisms rotate with the rotating drum 1, and can also play a role in stirring the silt during the sludge suction and water spraying process. The port silt treatment device also includes a silt purification mechanism, which includes a vertically arranged, hollow cylindrical purification tank 91 and multiple partition cylinders 92 coaxially arranged inside and outside the purification tank. The multiple partition cylinders 92 divide the purification tank 91 radially from the inside to the outside into multiple purification pools 93. The height of the multiple partition cylinders 92 increases radially from the inside to the outside, and the height of the outermost partition cylinder 92 is less than the height of the purification tank 91. The bottom of each partition cylinder 92 is connected to the purification pool. The bottom of the bucket 91 is sealed. A ring-shaped filter screen 94 is preferably provided between the top of each partition cylinder 92 and the top surface of the purification bucket. When the water in the outer purification tank 93 overflows, it overflows into the adjacent inner purification tank 93, achieving sedimentation and purification of the sludge and wastewater. A ring-shaped first sludge-drawing channel is formed between the inner and outer pipes of the first sleeve 4, and a ring-shaped second sludge-drawing channel is formed between the inner and outer pipes of the second sleeve 5. The inner pipe of the first sleeve 4 serves as the first water conveyance channel, and the inner pipe of the second sleeve 5 serves as... The second water supply channel has a first sleeve 4 that rotates together with the rotating drum 1, and a second sleeve 5 that is coaxially located at the top of the first sleeve 4. Preferably, the second sleeve 5 can be connected to the purification tank 91 by setting a bracket that is connected to the outer wall of the purification tank 91. Similarly, the sludge pump 25 and the high-pressure water pump 35 can be connected to the outer wall of the purification tank 91 by setting a connector. The water supply direction of the high-pressure water pump 35 is to transport the water of the innermost purification pool 93 to the water supply pipe 34.The lower circumferential side of the second sleeve 5 is rotatably connected to the top surface of the rotating drum 1, and the bottom of the second sleeve 5 is rotatably and sealingly connected to the bottom of the first sleeve 4 (ensuring that while the rotating drum 1 drives the sludge pumping mechanism and the water spraying mechanism to rotate around the axis of the rotating drum 1, it will not affect the normal transport of sludge and filtered water). The first sludge pumping channel and the second sludge pumping channel are connected to form a sludge transport channel, and the first water transport channel and the second water transport channel are connected to form a water transport channel. The transport channel is connected to the outermost purification tank 93 through the sludge transport pipe 24. Preferably, the sludge transport pipe 24 is connected to the water inlet hole set at the bottom of one side of the outermost purification tank 93 (the outermost purification tank 93 is equipped with a baffle 95, which corresponds to the water inlet hole. The baffle 95 reduces the impact force of sludge entering the outermost purification tank 93 near the inner side). The sludge pump 25 is started. The sludge pumped by the sludge pumping mechanism is transported to the outermost purification tank 93 through the sludge conveying channel and sludge conveying pipe 24. The sludge, impurities and dirt in the mixture of sludge and water in the outermost purification tank 93 settle to the bottom of the outermost purification tank 93. When the water level in the outermost purification tank 93 is higher than the outermost separator 92, the water overflows to an adjacent purification tank 93 located in the next outermost layer. The water flows to the next level (inner side) purification tank 93 in sequence, realizing the sedimentation and purification of sewage. The purified water is collected in the innermost purification tank 93. The high-pressure water pump 35 is started to transport the purified water to each spray mechanism through the water conveying pipe 34 and water conveying channel. The spray mechanism sprays the water separated from the sludge back to the bottom of the water and uses the impact force of the spray water to break up and disperse the sludge.

[0057] The port sludge treatment device provided by this invention can efficiently pump out sludge while separating the water in the sludge in a timely manner and recovering 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 and disperse the sludge, reducing the load on the ship, reducing the number of times the ship has to travel back and forth during the sludge treatment process, and improving the efficiency of dredging operations.

[0058] The port sludge treatment device provided by this invention is used during navigation or port dredging. The device is placed on a ship, which navigates to the area to be dredged in the channel or port. A winch lowers the rotating drum 1 to the bottom of the water. The sludge pumping mechanism and the water spraying mechanism are lowered to the bottom along with the drum 1. The sealing of each pipe is checked, and then the drive mechanism is activated to rotate the drum 1 around its own axis. This, in turn, drives the sludge pumping mechanism and the water spraying mechanism to rotate around the axis of the drum 1. Subsequently, the sludge pump 25 is activated, driving the sludge pumping mechanism to suck up the sludge. The sludge is sucked up by the suction mechanism and transported through the sludge conveying pipe and the sludge transport pipe 24 to the bottom. In the outer purification tank 93, the sludge undergoes multi-stage sedimentation purification through multiple purification tanks 93. The purified and filtered water is collected in the innermost purification tank 93. When the water level in the innermost purification tank 93 reaches a preset height (e.g., the water level is higher than 0.5m), the high-pressure water pump 35 is activated. The water in the innermost purification tank 93 is further filtered and purified through the filter screen in the outlet. Then, it is transported to the water spraying mechanism through the water supply pipe 34 and the water delivery pipe. The water spraying mechanism sprays the water to the bottom of the water. The sprayed water can generate an impact force on the sludge at the bottom, breaking and dispersing the sludge and preventing the clumps of sludge from clogging the pipes.

[0059] In another technical solution, the port silt treatment device further includes a counterweight 6, which is a cylindrical structure coaxially rotatable at the bottom of the rotating cylinder 1. The bottom of the counterweight 6 is provided with a plurality of anchor rods 61 spaced circumferentially. The center of the circular structure formed by the plurality of anchor rods 61 is located on the axis of the counterweight 6. The top of each anchor rod 61 is slidably connected to the counterweight 6 in the vertical direction, and the bottom is provided with a conical tip. The anchor rods 61 move downward relative to the counterweight 6 under the drive of the driving mechanism. A counterweight 6 is installed at the bottom of the rotating drum 1, and multiple anchor rods 61 are installed at the bottom of the counterweight 6 that can be inserted into the silt at the bottom of the water. The counterweight 6 is rotatably connected to the rotating drum 1 and does not interfere with the rotation of the rotating drum 1 around its own axis. Multiple anchor rods 61 are installed at the bottom of the counterweight 6, and the upper part of each anchor rod 61 is slidably connected to the counterweight 6 in the vertical direction, that is, the anchor rod 61 can move relative to the counterweight 6 in the vertical direction. The bottom of the anchor rod 61 is provided with a conical tip, which facilitates the insertion of the anchor rod 61 into the silt at the bottom of the water to achieve the positioning of the counterweight 6. The counterweight 6 and the anchor rods 61 can play a role in lateral positioning of the rotating drum 1, so as to prevent the rotating drum 1 from shifting laterally due to water buoyancy or the lateral flow force of water, which would affect the normal progress of the dredging operation.

[0060] In another technical solution, the port sludge treatment device includes a sludge pumping mechanism comprising a sludge pumping main pipe 21 extending radially along the rotating drum 1 and a plurality of sludge pumping branch pipes 22 spaced axially along the sludge pumping main pipe 21. One end of each sludge pumping main pipe 21 is connected to the outer tube of the first sleeve 4, and the other end extends horizontally radially to the outside of the rotating drum 1. The plurality of sludge pumping branch pipes 22 are located outside the rotating drum 1, and the upper end of each sludge pumping branch pipe 22 is connected to the corresponding sludge pumping main pipe 21.

[0061] Each main sludge suction pipe 21 is equipped with a sludge suction hopper 23 at the other end and at the lower end of each branch sludge suction pipe 22.

[0062] In the above technical solution, the present invention discloses the specific structure of the sludge pumping mechanism. Each sludge pumping mechanism includes a sludge pumping main pipe 21 arranged horizontally along the radial direction of the rotating drum 1. One end of each sludge pumping main pipe 21 is located inside the rotating drum 1 and communicates with the outer tube of the first sleeve 4 (the annular space between the outer tube and the inner tube). The other end extends horizontally along the radial direction of the rotating drum 1. Multiple sludge pumping branch pipes 22 are arranged at intervals along the axial direction at the bottom of the sludge pumping main pipe 21. The upper end of each sludge pumping branch pipe 22 is connected to the sludge pumping main pipe 21. The sludge pumping branch pipes 22 can be arranged vertically or non-vertically, and can be arranged on the sludge pumping main pipe 21 at different inclination angles. Preferably, multiple sludge pumping holes are arranged at intervals on the circumferential side surfaces of both the sludge pumping main pipe 21 and the sludge pumping branch pipes 22. A sludge suction hopper 23 is provided at the other end of both the sludge pumping main pipe 21 and the sludge pumping branch pipes 22. The arrangement of multiple sludge pumping branch pipes 22 and the sludge pumping main pipe 21 that collects the sludge from the multiple sludge pumping branch pipes 22 can improve the pumping rate.

[0063] In another technical solution, the port sludge treatment device includes a water spraying mechanism comprising a main water spraying pipe 31 extending radially along the rotating drum 1 and water spraying branch pipes 32 spaced axially at the bottom of the main water spraying pipe 31. One end of each main water spraying pipe 31 is connected to the lower end of the inner tube of the first sleeve 4, and the other end is sealed. The upper end of each water spraying branch pipe 32 is connected to the corresponding main water spraying pipe 31, and the lower end extends vertically downward and is provided with a high-pressure nozzle 33. Each water spraying mechanism includes a main water spraying pipe 31 extending radially along the rotating drum 1 and multiple water spraying branch pipes 32 connected to the main water spraying pipe 31. The water spraying branch pipes 32 extend vertically downward and are provided with a high-pressure nozzle 33 at their lower ends. Water in the innermost purification tank 93 is transported to the main water spraying pipe 31 via a water supply pipe 34 and a water transport channel, then distributed to each water spraying branch pipe 32, and finally sprayed into the sludge at the bottom of the water through the high-pressure nozzle 33. This process not only recycles the water but also breaks up and disperses the sludge.

[0064] In another technical solution, the port sludge treatment device further includes multiple dispersing mechanisms, which are spaced circumferentially around the outer periphery of the rotating drum 1. Each dispersing mechanism does not interfere with each sludge pumping mechanism or each water spraying mechanism.

[0065] Each dispersing mechanism includes a stirring main rod 71 connected at one end to the circumferential side of the rotating drum 1, and a plurality of stirring support rods 72 spaced apart on the stirring main rod 71. Multiple dispersing mechanisms are arranged around the rotating drum 1. Each dispersing mechanism includes a stirring main rod 71 connected to the circumferential side of the rotating drum 1, and stirring support rods 72 spaced apart on the stirring main rod 71. The rotation of the rotating drum 1 drives the dispersing mechanism to rotate, allowing the dispersing mechanism to agitate and disperse the clumps of sludge.

[0066] In another technical solution, the port sludge treatment device has a main stirring rod 71 that is a telescopic rod with inner and outer rods slidingly sleeved together. The free end of each outer rod is hinged to the side wall of the rotating drum 1. Multiple stirring support rods 72 are provided at intervals on both the outer and inner rods.

[0067] The counterweight 6 is externally fitted with a rotating collar; each disintegration mechanism is provided with a telescopic cylinder, the cylinder body 73 of each telescopic cylinder is located on the collar, and the free end of the telescopic rod 74 of the telescopic cylinder extends horizontally along the radial direction of the rotating cylinder 1 and is hinged to the free end of the corresponding inner rod.

[0068] In the above technical solution, the present invention further configures the stirring main rod 71 as a telescopic rod body, which can be retracted when idle (not stirring), reducing the overall volume of the rotating drum 1 when lowering and raising it, facilitating the lowering of the main body of the rotating drum 1; specifically, the stirring main rod 71 is extended and retracted by the drive of the telescopic cylinder. Preferably, two mud-drawing mechanisms are provided and symmetrically arranged on the left and right sides of the rotating drum 1 (as shown in Figure 4), and two water-spraying mechanisms are provided and symmetrically arranged at the front and rear of the rotating drum 1 (as shown in Figure 4). A dispersing mechanism is provided between any adjacent mud-drawing mechanism and water-spraying mechanism, that is, there are four dispersing mechanisms, each of which is located below the mud-drawing mechanism and the water-spraying mechanism.

[0069] In another technical solution, the drive mechanism of the port sludge treatment device includes:

[0070] A dual-axis motor 81 is located inside the counterweight 6. The two output shafts 811 of the dual-axis motor 81 are coaxial with the rotating drum 1. The free ends of the two output shafts 811 extend upward and downward, respectively. Each of the free ends of the two output shafts 811 of the dual-axis motor 81 is provided with an iron block 812.

[0071] The first rotating shaft 82 is coaxially fixed to the bottom of the rotating cylinder 1; the bottom of the first rotating shaft 82 is provided with a first electromagnet 821 that contacts the upper iron block 812;

[0073] Multiple sleeves 84 are provided, with one sleeve 84 corresponding to each anchor rod 61. The top of the sleeve 84 is rotatably connected to the counterweight 6. The upper end of each anchor rod 61 is inserted into the interior of the corresponding sleeve 84 and is rotatably connected to the inner wall of the sleeve 84 by threads. The side of the anchor rod 61 is provided with a sliding groove in the vertical direction. A second gear disk 841 is coaxially fixedly sleeved on each sleeve 84, and each second gear disk 841 meshes with the first gear disk 832.

[0074] Multiple sliders 85 are provided, with one slider 85 corresponding to each anchor rod 61. One side of each slider 85 is connected to the counterweight block 6, and the other end is slidably disposed in the groove.

[0075] In the above technical solution, the present invention further discloses the specific structure of a drive mechanism for driving the rotating drum 1 to rotate and also for driving the anchor rods 61 to move up and down. The drive mechanism includes a dual-axis motor 81 disposed inside the counterweight block 6, a first rotating shaft 82 coaxially fixed to the bottom of the rotating drum 1, a second rotating shaft 83 coaxially rotatably disposed inside the counterweight block 6, sleeves 84 corresponding one-to-one with multiple anchor rods 61, and multiple sliders 85 that slide vertically connecting the anchor rods 61 and the counterweight block 6. Preferably, the drive mechanism is a dual-axis motor 81 disposed inside the counterweight block 6. The weight block 6 has multiple cavities for housing the dual-axis motor 81, the second rotating shaft 83, and multiple sleeves 84. The corresponding cavities are interconnected to allow the components to cooperate and move together. The two output shafts 811 of the dual-axis motor 81 are coaxially rotatable with the rotating drum 1 in their respective cavities. The free ends of the two output shafts 811 extend upward and downward through their respective cavities and are each equipped with an iron block 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 cylinder 1 is fixedly connected, and the lower end is provided with a first electromagnet 821 that contacts the upper iron block 812. The second rotating shaft 83 is coaxially disposed inside the counterweight 6 and located below the dual-axis motor 81. The upper end of the second rotating shaft 83 is provided with a second electromagnet 831 that contacts the lower iron block 812, and the lower end is rotatably connected to the bottom of the corresponding accommodating cavity. A first gear disk 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. Next, each anchor rod 61 is slidably connected to the corresponding receiving cavity in the vertical direction via a 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 6. A second gear disk 841 is coaxially fixed on each sleeve 84, and each second gear disk 841 meshes with the first gear disk 832. Thus, by rotating the second rotating shaft 83, all sleeves 84 can be rotated, thereby driving all anchor rods 61 to move in the vertical direction relative to the counterweight 6.

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

[0077] The present invention also provides a method for treating port silt, which employs the aforementioned port silt treatment device; the port silt treatment method includes the following steps:

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

[0079] S2. Start the drive mechanism to drive the rotating drum 1 to rotate around its own axis; then start the sludge pump 25 to suck up the sludge through the sludge pumping mechanism, and transport the sludge to the outermost purification tank 93 through the first sleeve 4, the second sleeve 5 and the sludge conveying pipe 24; for any purification tank 93, the sludge settles in the purification tank 93 and the upper water overflows to an adjacent purification tank 93.

[0080] S3. When the water level of the innermost purification tank 93 reaches the preset height, the high-pressure water pump 35 is started, and high-pressure water is sprayed through the water spraying mechanism to transport the water in the innermost purification tank 93, which has undergone multi-stage purification, back to the port or ship.

[0081] In the above technical solution, the present invention utilizes the port silt treatment device to treat the silt at the bottom of the port, which can achieve efficient dredging while timely separation of water in the silt and recycling of the water, greatly improving the dredging efficiency.
