[0002] Port channels are affected by ocean currents and rivers, which often accumulate large amounts of silt, requiring frequent cleaning. In order to improve cleaning efficiency, it is necessary to drain the excess water back into the sea after the silt is sucked out of the water.

The inner filter cylinder and the outer cylinder work together to centrifugally filter and separate the sludge, while the screw conveyor transports the sludge.

The centrifugation to remove water from sludge takes a long time, and materials cannot be added or removed midway, resulting in low separation efficiency. In addition, the existing machines only separate sludge and water through single-stage centrifugal filtration, which can easily cause too much sludge to enter the machine, reduce centrifugal efficiency, and result in a slow separation speed.

[0028] like Figure 3 and Figure 4 As shown, the primary filtration device 04 includes a reducing connector 41, a pipe 42, a slip ring 43, multiple rotating shafts 44, a support 45, multiple sets of magnets 46, and a screen 47. The reducing connector 41 is installed at the rear end of the inlet pipe of the multi-port connector 15. The pipe 42 is installed at the rear end of the reducing connector 41. The slip ring 43 is rotatably installed inside the pipe 42. Multiple rotating shafts 44 are evenly spaced inside the slip ring 43.

The support 45 is installed on the multiple rotating shafts 44, and the support 45 and the multiple rotating shafts 44 are rotatably connected.

[0029] like Figure 6 As shown, the multi-station filtration device 05 includes two electrically controlled valves 51, two belt filter bodies 52, two sets of filter bags 53, two hinges 54, and two cover plates 55. The two electrically controlled valves 51 are respectively installed on the two output pipes of the pipe 3 18.

[0030] First, the excavated sludge is fed into pipe 42. A screen 47 filters and blocks large particles of impurities in the sludge, while a magnet 46 attracts and intercepts magnetic metal impurities. A freely rotating bracket 45 drives the magnet 46 to rotate, reducing collisions between the magnet and the magnetic metal impurities and improving the collection rate. The sludge then disperses through a multi-port connector 15 and pipe 16 into multiple hydrocyclones 13. The hydrocyclones 13 separate the sludge and water through their structure. The separated sludge is temporarily stored in a sludge box 12, while the remaining sludge and water enter pipe 18. An electrically controlled valve 51 adjusts the flow direction of the sludge and water within pipe 18. A belt filter body 52 and a filter bag 53 work together to filter and separate the remaining sludge and water. The two belt filter bodies 52 allow for easy cleaning of one without shutting down the system. The cleaned sludge can be easily discharged through the feed slope of the drainage box 27. The sludge is poured into the sludge box 12, and then the motor 24, hydraulic cylinder 29, hydraulic cylinder 73, and motor 37 are turned on. Motor 24 provides power to drive the auger 22 to rotate and transport the sludge in the sludge box 12 to the drainage tank 27.

When the baffle 75 moves to the right, it closes the drainage box 27, preventing the sludge from flowing out of the drainage box 27 when it is being squeezed and drained. When the baffle 75 moves to the left, it opens the discharge port of the drainage box 27, making it easier to discharge the sludge inside the drainage box 27. The second motor 37 provides power, which is transmitted through the second reducer 36, sprocket 35, chain 38 and rotating shaft 34, driving the discharge plate 33 to move back and forth.

[0034] First, the excavated sludge is fed into the homogenizing cylinder 62. Then, motor 67 is turned on, providing power to drive the agitator 65 to rotate and homogenize the sludge. Afterward, the sludge enters pipe 42. A screen 47 filters out large particles of impurities, and a magnet 46 attracts and intercepts magnetic metallic impurities. The freely rotating support 45 drives the magnet 46 to rotate, reducing collisions between the magnet and magnetic metallic impurities and increasing the collection rate. Finally, the sludge passes through a multi-port connector. Pipeline 15 and Pipeline 2 16 disperse the sludge and water into multiple hydrocyclones 13. The hydrocyclones 13 separate the sludge and water through their own structure. The separated sludge is temporarily stored in the sludge box 12, while the remaining sludge and water enter Pipeline 3 18. The electrically controlled valve 51 adjusts the flow direction of the sludge and water within Pipeline 3 18. The belt filter body 52 and filter bag 53 work together to filter and separate the remaining sludge and water. The two belt filter bodies 52 work together to facilitate the filtering of one of the belt filter bodies 52 without shutting down the system. 2. Cleaning is performed.

Motor 24 provides power to drive the auger 22 to rotate and transport the sludge in the sludge box 12 into the drainage tank 27. Hydraulic cylinder 29 provides power to drive the pressure plate 71 to move up and down. The pressure plate 71 moves down and, together with the filter screen of the drainage tank 27, discharges excess water from the sludge into the water tank 25. The drain pipe 26 discharges the water from the water tank 25 into the sea. Hydraulic cylinder 73 provides power to drive baffle 75 to move left and right. Baffle 75 moves to the right to close the drainage tank 27, preventing the sludge from flowing out of the drainage tank 27 when it is being squeezed and drained. Baffle 75 moves to the left to open the discharge port of the drainage tank 27, making it easier to discharge the sludge inside the drainage tank 27. Motor 37 provides power, which is transmitted through reducer 36, sprocket 35, chain 38 and shaft 34 to drive discharge plate 33 to move back and forth. Discharge plate 33 moves forward to push the sludge inside the drainage tank 27 to the outside of the drainage tank 27.

[0035] like Figures 1 to 7 As shown, this utility model discloses a port channel sludge separation and dewatering device. During operation, the dredged sludge is first fed into a homogenizing cylinder 62. Then, motor 67 is turned on, providing power to drive agitator 65 to rotate and homogenize the sludge. Afterward, the sludge enters pipe 42. A screen 47 filters and blocks large particles of impurities in the sludge, while magnet 46 attracts and intercepts magnetic metallic impurities. The freely rotating support 45 drives magnet 46 to rotate, thereby reducing collisions between magnet 46 and magnetic metallic impurities and improving water removal efficiency. To improve the collection rate of magnetic metal impurities, the sludge is then dispersed into multiple hydrocyclones 13 through multi-port connector 15 and pipe 16. The hydrocyclones 13 separate the sludge and water through their structure. The separated sludge is temporarily stored in sludge box 12, while the remaining sludge and water enter pipe 18. Electrically controlled valve 51 adjusts the flow direction of the sludge and water within pipe 18. The belt filter body 52 and filter bag 53 work together to filter and separate the remaining sludge and water. The two belt filter bodies 52 work together to facilitate operation without shutting down the system. In this case, one of the belt filter bodies 52 is cleaned. The cleaned sludge can be easily poured into the drainage tank 27 through the feed slope. Then, motor 24, hydraulic cylinder 29, hydraulic cylinder 73, and motor 37 are turned on. Motor 24 provides power to drive the auger 22 to rotate and transport the sludge in the sludge box 12 into the drainage tank 27. Hydraulic cylinder 29 provides power to drive the pressure plate 71 to move up and down. The pressure plate 71 moves down and cooperates with the filter screen of the drainage tank 27 to discharge excess water from the sludge into the water tank 25. The drain pipe 26 drains the water inside the water tank 25. The water is discharged into the sea. Hydraulic cylinder 73 provides power to drive baffle 75 to move left and right. Baffle 75 moves to the right to close the drainage tank 27, preventing the silt from flowing out of the drainage tank 27 when the silt is squeezed and drained. Baffle 75 moves to the left to open the discharge port of the drainage tank 27, making it easier to discharge the silt inside the drainage tank 27. Motor 37 provides power, which is transmitted through reducer 36, sprocket 35, chain 38 and shaft 34 to drive discharge plate 33 to move back and forth. Discharge plate 33 moves forward to push the silt inside the drainage tank 27 to the outside of the drainage tank 27.

[0036] The multiple cyclone separators 13, auger 22, motor 1 24, hydraulic cylinder 1 29, hydraulic cylinder 2 73, four sprockets 35, motor 2 37, two chains 38, multiple sets of magnets 46, two electrically controlled valves 51, two belt filter bodies 52, two sets of filter bags 53, and motor 3 67 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0037] The main functions achieved by this utility model are as follows: by setting up a cyclone separation filter device 01, a primary filter device 04, and a multi-station filter device 05, sludge and water are continuously separated. During separation, the machine can be cleaned and fed without stopping, improving separation efficiency. Furthermore, by setting up the cyclone separation filter device 01, the primary filter device 04, and the multi-station filter device 05, sludge and water are continuously filtered and separated in three stages using a combination of screen filtration, cyclone separation filtration, and bag filtration. This allows sludge to be quickly discharged from the machine for storage, ensuring continuous filtration efficiency and improving the machine's separation speed. This solves the problems of existing machines that use centrifugal filtration to separate sludge and water, where the centrifugation process for sludge removal is time-consuming and materials cannot be added or removed midway, resulting in low separation efficiency. Additionally, existing machines that only use single-stage centrifugal filtration to separate sludge and water are prone to allowing excessive sludge to enter the machine, reducing centrifugal efficiency and resulting in slow separation speed.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
