[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] First embodiment: like Figures 1 to 7 As shown, this embodiment provides a multiple water separation and dewatering device for sludge used in port and channel construction, comprising a frame 1, a straight cylinder 2, a hopper 3 and a stirring structure 5. The straight cylinder 2 is fixedly arranged on the frame 1, and the hopper 3 is fixedly arranged on the top of the vertically arranged straight cylinder 2. Figure 3 , Figure 4As shown, the straight cylinder 2 includes a heating chamber 21, a split chamber 22, a driving chamber 23 and a stirring chamber 24 from top to bottom. The heating chamber 21 is provided with a plurality of retention tubes 4 along the circumference of the axis of the straight cylinder 2, and the retention tubes 4 are made of metal copper. Metal copper has good thermal conductivity. The vertically arranged retention tubes 4 are fixed on the bottom wall of the split chamber 22, and the bottom of the retention tubes 4 are in the driving chamber 23; and the retention tubes 4 pass through the driving chamber 23 and the heating chamber 21 in turn to be connected with the hopper 3, and the bottom end of the retention tube 4 is connected with the stirring chamber 24 through the bending tube 27. The heating chamber 21 is filled with heating oil (not shown) and a heating rod (not shown) is arranged. The heating rod adopts the existing technology, so it will not be described in detail. The heating rod can heat the heating oil.

[0024] like Figure 3 As shown, a first solenoid valve 41 is arranged at the top of each retention tube 4, and a second solenoid valve 42 is arranged at the connection between each bending tube and the retention tube 4.

[0025] The silt is salvaged from the port channel or transported to the hopper 3 by a pump body. The silt is statically treated in the hopper 3 so that the silt water and the fixed silt are separated into layers. The separated water in the hopper 3 is extracted through the existing water suction pipe, thus forming the first silt dewatering process; Further, multiple first solenoid valves 41 are opened to allow the fixed sludge to flow into the retention tube 4, and the heating rod is driven to start working. The heating rod heats the heating oil in the heating chamber 21, so that the retention tube 4 can be quickly heated. The sludge flows in the retention tube 4, and the heated retention tube 4 heats the sludge. After the sludge in the retention tube 4 is heated to a certain temperature, the moisture is discharged from the top of the retention tube 4, thus forming a second sludge dehydration process. Finally, the second solenoid valve 42 is opened to discharge it to the next process.

[0026] Through this structure, the sludge sedimentation and stratification dehydration and heating and drying dehydration are combined to achieve a secondary dehydration effect. In addition, the low-temperature sludge is dried by heating, which has a good dehydration effect.

[0027] Second embodiment: Preferably, in this embodiment, a stirring structure 5 for stirring sludge is provided in the stirring chamber 24, and a dosing pipe 25 and a discharge pipe 26 are provided in communication with the stirring chamber 24. The discharge pipe 26 is located at the bottom of the stirring chamber 24, and the stirring structure 5 includes a first motor 51 and a rotating shaft 52, a plurality of rotating frames 53 are fixed to one end of the rotating shaft 52, and the other end of the rotating shaft 52 passes through the stirring chamber 24, the driving chamber 23 and is fixedly connected to the output shaft of the first motor 51 located in the segmentation chamber 22, and the base of the first motor 51 is fixedly provided on the bottom wall of the segmentation chamber 22. When the first motor 51 is driven to work, the first motor 51 drives the plurality of rotating frames 53 to rotate through the rotating shaft 52.

[0028] The bottom end of the retention tube 4 is connected to the stirring chamber 24 through a bent tube 27, so that the sludge flows into the stirring chamber 24, and a curing agent is added to the stirring chamber through a dosing tube 25, driving the stirring structure 5 to work, and the stirring structure 5 stirs the curing agent and the heated sludge so that the two are fully mixed, thus forming a third dehydration and curing process, and the sludge is pre-heated, and heating can accelerate the chemical reaction, so that the curing agent reacts with the water and other substances in the sludge faster, thereby shortening the curing time. The three curing processes further improve the sludge dehydration and curing efficiency.

[0029] In addition, the present invention is particularly suitable for treating port and waterway sludge in cold seasons.

[0030] Second embodiment: like Figure 4 , Figure 5 As shown, a first auger 6 is axially rotatably arranged in each retention tube 4, and the shaft of the first auger 6 is coaxially connected to a rotating rod 76, and the rotating rod 76 penetrates into the driving cavity 23 to connect with the driving member 7. The driving member 7 includes a main spur gear 71 and a plurality of secondary spur gears 72, and each rotating rod 76 is fixedly sleeved with a secondary spur gear 72. The main spur gear 71 is sleeved on the rotating shaft 52, as shown in FIG. Figure 7 As shown, the inner ring of the main spur gear 71 is provided with a limiting groove 710, such as Figure 5 , Figure 7 As shown, the rotating shaft 52 is fixedly provided with a limit block 520, and the limit block 520 is plugged into and matched with the limit groove 710. The top wall of the main spur gear 71 is coaxially fixedly provided with an annular housing 73, and the top wall of the annular housing 73 is provided with an annular groove 730. The main spur gear 71 can mesh with a plurality of auxiliary spur gears 72. A plurality of cylinders 74 are arranged along the axis circumference of the straight cylinder 2 in the dividing chamber 22, and the piston rods of the cylinders 74 are sequentially inserted into the driving chamber 23 and the driving block 75 is fixedly provided in the annular groove 730.

[0031] This structure is divided into two states: State 1: The main spur gear 71 and the plurality of secondary spur gears 72 are in meshing state, the piston rod of the cylinder 74 is inserted into the annular groove 730 in turn to fix the driving block 75, and the annular housing 73 in the rotating state is in a non-contact state with the driving block 75. In addition, the limit block 520 is plugged into the limit groove 710. The first motor 51 is driven to start working, the output shaft of the first motor 51 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the plurality of secondary spur gears 72 to rotate through the main spur gear 71, and the secondary spur gear 72 drives the first auger 6 to rotate through the rotating rod 76. The rotation speed of the first auger 6 controls the feeding speed of the sludge into the stirring chamber 24, so that the length of time the sludge stays in the retention tube 4 can be controlled, thereby affecting the heating time of the sludge. At this time, the rotating frame 53 can also stir the sludge in the stirring chamber 24.

[0032] State 2: When enough sludge enters the stirring chamber 24, the multiple cylinders 74 are driven to start working synchronously, and the piston rods of the cylinders 74 begin to contract. The piston rods drive the driving blocks 75 to move upward, and the driving blocks 75 drive the main spur gear 71 to move upward through the annular shell 73, so that the main spur gear 71 and the multiple sub-spur gears 72 are in a separated state, driving the first motor 51 to work, and the first motor 51 drives the multiple rotating frames 53 to rotate through the rotating shaft 52, and the multiple rotating frames 53 stir the curing agent and the heated sludge to make the two fully mixed.

[0033] like Figure 3 , Figure 4 As shown, the bottom end of the discharge pipe 26 is connected to a horizontal pipe 8, a second auger 81 is rotatably arranged in the horizontal pipe 8, a second motor 82 is fixedly arranged at one end of the horizontal pipe 8, the output shaft of the second motor 82 is coaxially connected with the shaft of the second auger 81, and a container (not shown) is detachably arranged at the other end of the horizontal pipe 8. After the sludge is mixed, the second motor 82 drives the second auger 81 to rotate, and the second auger 81 drives the sludge to be pushed out of the container, thus completing the solidification treatment of the sludge dehydration. A conical body 9 is coaxially fixedly arranged at the top of the straight cylinder 2, the conical body 9 is located in the hopper 3, and the closed end of the conical body 9 is arranged upward. The annular wall of the stirring chamber 24 is a sandwich structure 240, and a heating wire 241 is arranged in the sandwich structure 240. The heating wire 241 performs sludge heating treatment on the sludge in the stirring chamber 24.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
