Description

Technical Field

[0001] The present invention relates to the technical field of waterway dredging, and in particular to a waterway dredging mud solidification device and method. Background Art

[0002] The construction and maintenance of ports (increasing port throughput), ensuring the flood discharge capacity of rivers, ensuring the smooth flow of waterways, and enhancing the flood storage capacity of lakes all require dredging of rivers and lakes, which generates large amounts of dredged mud. At the same time, with the acceleration of industrialization and urbanization, water pollution is becoming increasingly serious, and dredging of bottom sediment is necessary to eliminate internal sources of water pollution. Therefore, when repairing and treating polluted rivers and lakes, ecological dredging is necessary, which also generates large amounts of dredged mud.

[0003] Most existing slurry solidification processes typically begin with filter pressing the slurry through a filter plate or screen, followed by adding a curing agent to the filtered slurry and using a stirring rod to solidify it. However, in actual use, when the filter plates and screens filter the slurry, some slurry enters the filter holes, reducing the subsequent water filtration performance of the filter plates or screens. Furthermore, the stirring process ignores the slurry's inherent heavy solute content, poor fluidity, and tendency to stratify. This makes it difficult to achieve a good mixing effect after adding a curing additive during the mixing process, resulting in prolonged curing time and easy disintegration of the slurry during the solidification process.

[0014] The present invention also discloses a waterway dredging mud solidification method, which is processed by applying the waterway dredging mud solidification device described above, and includes the following steps: S1: Connect the mud discharge pipe to the feed port on the top of the separation cylinder, and then discharge the mud into the separation cylinder; S2: Control the operation of the first motor. When the first motor is running, it drives the driving gear to engage with the driven gear on the filter drum, thereby causing the filter drum to drive the mud to rotate centrifugally, so that the mud is initially separated from the water. S3: Then the second electric push rod is controlled to retract to drive the bottom plate to flip. The bottom of the filter drum is now open. The second motor is controlled to operate. The second motor drives the spiral conveying blades on the outer side of the conveying shaft to rotate, so that the spiral conveying blades press down the mud blocks that have been initially separated from the mud and water in the filter drum. As the inner diameter of the filter drum gradually decreases, the water in the mud blocks is further squeezed out and enters the water receiving shell. The mud blocks removed from the filter drum are cut into several strips by the wire mesh frame, and then the cut mud blocks fall to the bottom of the mixing drum; S4: Then control the first electric push rod to push the separation cylinder to move back and forth in the mixing cylinder, control the cylinder dredging component to work, dredge the filter holes of the filter cylinder, and remove the mud in the filter holes; S5: When the separation cylinder moves back and forth, it drives the annular powder box to move, so that the curing agent powder in the annular powder box is shaken and loosened, and when the cylinder dredging component works, it drives the powder mixing component to work, so that the curing agent powder in the annular powder box is fully mixed with the mud blocks removed from the filter cylinder.

[0015] It can be seen from the above technical solutions that the present invention has the following beneficial effects: 1. In the present invention, the filter cylinder is dredged by the cylinder dredging component to ensure the subsequent separation efficiency and separation effect of the filter cylinder on mud and water, and the cylinder dredging component drives the powder mixing component to work when working, so that the annular powder box is shaken to avoid the lime powder in the annular powder box from agglomerating and affecting the mixing effect with the mud blocks after filtration, thereby ensuring the mud solidification efficiency and solidification effect.

[0016] 2. In the present invention, when the separation cylinder is driven to move left and right in the mixing cylinder by the first electric push rod, the filter cylinder in the separation cylinder and the abutment plate at the end of the fixed rod are intermittently abutted. When the filter cylinder abuts, it is subjected to force vibration, so that the mud blocks on the inner wall of the mesh of the filter cylinder are loosened, and when the separation cylinder moves left and right, the piston is driven to move in the fixed tube through the connecting tube, so that the air in the fixed tube is discharged to the abutment plate through the exhaust telescopic tube, and is sprayed to the filter cylinder through the air jet port of the abutment plate, so that the mud blocks on the mesh of the filter cylinder are quickly cleared, thereby ensuring the subsequent mud-water separation effect and separation efficiency of the filter cylinder.

[0017] 3. In the present invention, a steel wire frame is provided at the discharge port, so that the mud blocks moved out of the discharge port are divided into a number of strip-shaped mud blocks. When the first electric push rod drives the separation cylinder to move left and right in the mixing cylinder, the several strip-shaped mud blocks moved out of the discharge port swing, thereby increasing the distance between the strip-shaped mud blocks, so that the lime powder sprayed out of the annular powder box is fully attached to the strip-shaped mud blocks, increasing the contact area between the lime powder and the mud blocks after filtration, and then the lime powder and the mud blocks are quickly and evenly mixed, thereby reducing the mud solidification time and ensuring the mud solidification effect.

[0018] 4. In the present invention, when the separation cylinder is driven to move left and right in the mixing cylinder by the first electric push rod, the lifting rod drives the movable plate to move back and forth up and down in the annular powder box to stir the lime powder. When the movable plate moves up and down, it drives the collar to move relative to the positioning rod. The guide block cooperates with the spiral track groove, so that when the collar moves up and down with the movable plate, it drives the stirring blades to further stir the lime powder in the annular powder box, thereby avoiding agglomeration of the lime powder and ensuring that the lime powder and the mud blocks are fully mixed.

[0019] 5. In the present invention, the piston slides back and forth frequently in the fixed tube, causing the inner wall of the fixed tube to heat up, and the fixed tube heats the air drawn into it. The heated air is discharged into the annular powder box through the exhaust pipe, so that the lime powder in the annular powder box remains dry, effectively preventing it from agglomerating, and further ensuring that the lime powder and mud blocks are evenly mixed.

[0024] Specifically, the mud discharge pipe is connected to the feed port 201 at the top of the separation cylinder 2, and then the mud is discharged into the separation cylinder 2, and the separation cylinder 2 is controlled to rotate, so that the filter cylinder 6 drives the mud to rotate centrifugally, so that the mud is initially separated from the water. Then, the second electric push rod 4 is controlled to contract to drive the bottom plate 2021 to flip. The bottom of the filter cylinder 6 is open at this time, and the mud blocks that have been initially separated from the water in the filter cylinder 6 fall to the bottom of the mixing cylinder 1. Then, the first electric push rod 3 is controlled to push the separation cylinder 2 to move back and forth left and right in the mixing cylinder 1, and the cylinder dredging component is controlled to work, and the filter holes of the filter cylinder 6 are dredged to remove the mud blocks in the filter holes, thereby ensuring the subsequent separation efficiency and separation effect of the filter cylinder 6 for mud and water, and the cylinder dredging component drives the powder mixing component to work when working, effectively avoiding the influence of lime powder agglomeration on the mixing effect with the mud blocks after filtration, thereby ensuring the mud solidification efficiency and solidification effect.

The spiral conveying blade 802 is movably opposed to the inner wall of the filter cylinder 6, and the diameter of the filter cylinder 6 gradually decreases from top to bottom.

[0027] Specifically, after the mud is discharged into the separation drum 2, the first motor 7 is controlled to operate. When the first motor 7 is running, it drives the driving gear 701 to engage with the driven gear 702 on the filter drum 6, thereby causing the filter drum 6 to drive the mud to rotate centrifugally, so that the mud is initially separated from the water. The separated water enters the water receiving shell 5. Then, the second electric push rod 4 is controlled to contract so as to drive the bottom plate 2021 to flip. At this time, the bottom of the filter drum 6 is open, and the second motor 8 is controlled to operate. The second motor 8 drives the spiral conveying blade 802 on the outer side of the conveying shaft 801 to rotate, so that the spiral conveying blade 802 presses down the mud blocks that have been initially separated from the water in the filter drum 6. As the inner diameter of the filter cylinder 6 gradually decreases, the water in the mud blocks is further squeezed out and enters the water receiving shell 5. The mud blocks removed from the filter cylinder 6 are cut into several strips by the wire mesh frame 2022, and then the cut mud blocks fall to the bottom of the mixing cylinder 1. When the first electric push rod 3 drives the separation cylinder 2 to move left and right in the mixing cylinder 1, the several strips of mud blocks removed from the discharge port 202 swing, thereby increasing the distance between the strips of mud blocks, so that the lime powder is fully attached to the strips of mud blocks, increasing the contact area between the lime powder and the mud blocks after filtration, and then the lime powder and the mud blocks are quickly and evenly mixed, reducing the mud solidification time and ensuring the mud solidification effect.

[0028] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 As shown, as a preferred embodiment, on the basis of the above method, the cylinder dredging assembly further includes a fixed rod 9 fixed on the inner wall of the mixing cylinder 1 and slidingly connected to the water receiving shell 5, the fixed rod 9 is arranged on the side of the mixing cylinder 1 away from the first electric push rod 3, and the end of the fixed rod 9 away from the mixing cylinder 1 is fixed with an abutment plate 901, and the abutment plate 901 is movably abutted against the filter cylinder 6.

[0029] Furthermore, the cylinder dredging assembly also includes a fixed tube 10 fixed to the outside of the fixed rod 9, and a piston 1001 is slidably connected in the fixed tube 10. The piston 1001 divides the fixed tube 10 into a left cavity and a right cavity. An air inlet valve is provided in both the left cavity and the right cavity. A connecting tube 1002 is provided between the piston 1001 and the outer wall of the water receiving shell 5. The connecting tube 1002 is slidably connected to the fixed rod 9 and the fixed tube 10.

[0030] Specifically, by controlling the first electric push rod 3 to push the separation cylinder 2 to move back and forth left and right in the mixing cylinder 1, the filter cylinder 6 in the separation cylinder 2 is intermittently abutted against the abutment plate 901 at the end of the fixed rod 9. When the filter cylinder 6 abuts, it is subjected to force vibration, so that the mud blocks blocked on the inner wall of the mesh of the filter cylinder 6 are loosened. At the same time, the filter cylinder 6 can be driven to rotate during this period, so that the abutment plate 901 can abut and collide with different positions of the filter cylinder 6, ensuring that the filter cylinder 6 is subjected to uniform force, avoiding that it is always subjected to force at the same position and affecting its service life. When the separation cylinder 2 moves left and right, the piston 1001 is driven to move in the fixed pipe 10 through the connecting pipe 1002, so that the air in the fixed pipe 10 is discharged to the abutment plate 901 through the exhaust telescopic pipe 11, and is sprayed to the filter cylinder 6 through the air jet port 9011 of the abutment plate 901, so that the mud blocks blocked at the mesh of the filter cylinder 6 are quickly cleared, ensuring the subsequent mud-water separation effect and separation efficiency of the filter cylinder 6.

[0035] Furthermore, a protective tube 16 is fixedly provided on the outside of the collar 15 and sleeved on the outside of the positioning rod 14 to shield and cover the spiral track groove 141 .

[0036] Specifically, when the powder mixing assembly is active, the lifting rod 132 drives the movable plate 133 to move up and down in the annular powder box 12 to stir the lime powder. When the movable plate 133 moves up and down, it drives the collar 15 to move relative to the positioning rod 14. The guide block 152 cooperates with the spiral track groove 141, so that when the collar 15 moves up and down with the movable plate 133, it drives the stirring blade 151 to further stir the lime powder in the annular powder box 12, thereby avoiding the lime powder from agglomerating and ensuring that the lime powder and the mud block are fully mixed. The protective tube 16 is sleeved on the outside of the positioning rod 14 to prevent the powder from entering the spiral track groove 141 and affecting the normal sliding of the guide block 152, thereby ensuring the stable stirring work of the stirring blade 151.

[0037] The present invention also discloses a waterway dredging mud solidification method, which is processed by applying the waterway dredging mud solidification device described above, and includes the following steps: S1: Connect the mud discharge pipe to the feed port 201 at the top of the separation drum 2, and then discharge the mud into the separation drum 2; S2: Control the first motor 7 to operate.

The second motor 8 is controlled to operate. The second motor 8 drives the spiral conveying blade 802 outside the conveying shaft 801 to rotate, so that the spiral conveying blade 802 presses down the mud blocks that have been preliminarily separated from the mud and water in the filter drum 6. As the inner diameter of the filter drum 6 gradually decreases, the water in the mud blocks is further squeezed out and enters the water receiving housing 5. The mud blocks removed from the filter drum 6 are cut into a plurality of strips by the wire mesh frame 2022. The cut mud blocks then fall to the bottom of the mixing drum 1. S4: Then control the first electric push rod 3 to push the separation cylinder 2 to move back and forth in the mixing cylinder 1, control the cylinder dredging component to work, dredge the filter holes of the filter cylinder 6, and remove the mud in the filter holes; S5: When the separation cylinder 2 moves back and forth, it drives the annular powder box 12 to move, so that the curing agent powder in the annular powder box 12 is shaken and loosened, and when the cylinder dredging component works, it drives the powder mixing component to work, so that the curing agent powder in the annular powder box 12 is fully mixed with the mud blocks removed from the filter cylinder 6.
