Description

Technical Field

[0001] This invention relates to the field of river dredging technology, and in particular to a silt drying device for river dredging. Background Technology

[0002] River dredging generally refers to the management of river channels and is a water conservancy project. Over time, fallen leaves, silt and other debris settle to the bottom of the riverbed and form silt. If the silt is not cleaned regularly, it will seriously affect the water quality and directly affect the river's flood control, drainage and irrigation functions.

[0003] In existing technologies, when quickly dredging some small rivers, the water is usually drained first, then an excavator is used to dredge the silt from the bottom, and finally the silt is transported away. However, since the silt often contains a lot of sewage, it not only increases the volume and weight of the silt itself, but also causes sewage to drip everywhere during transportation. This not only adds extra burden to the transportation operation, but also has a bad impact on the road environment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a silt drying device for river dredging, which solves the technical problem that excessive water content in silt not only increases the burden during transportation but also damages the environment. The device effectively reduces the water content in silt and solidifies and shapes the silt, effectively preventing it from dripping during transportation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a silt drying device for river dredging, comprising a movable base, movable rollers at the lower end of the movable base, a solidification box movably mounted at the upper end of the movable base, silt conveying mechanisms on both the left and right sides of the solidification box, a pressing and dewatering mechanism at the upper end of the solidification box, and a solidification and shaping mechanism inside the solidification box. During river dredging, the silt conveying mechanisms transport the silt into the solidification box. During the transport process, the pressing and dewatering mechanism presses the silt to remove excess water. The pressing and dewatering mechanism includes mounting square plates symmetrically installed on the left and right sides of the solidification box. A sewage storage box is detachably mounted at the lower end of the mounting square plates, and a conveying mechanism is movably mounted at the upper end of the mounting square plates. The system consists of two cylindrical conveyor cylinders with a conveyor belt between them. Vertical slide rails are fixedly installed on both the front and rear sides of the mounting plate. Movable sliders are movably installed inside the vertical slide rails, and dewatering components are fixedly installed on the movable sliders. Mounting platforms are fixedly installed on the sides of the vertical slide rails, and movable rotating shafts are movably installed on the mounting platforms. Pressing protrusions are fixedly fitted on the outside of the movable rotating shafts. A drive motor for driving the movable rotating shafts is fixedly installed on the mounting platforms. A transmission assembly is provided between the movable rotating shafts and the conveyor cylinders. Material feeding scrapers are movably installed at the upper ends of the left and right sides of the curing box. The material feeding scrapers contact the outer surface of the conveyor belt. When the drive motor runs, it will cause the conveyor cylinders to rotate through the transmission assembly, and the rotating conveyor cylinders will transport the sludge into the interior of the curing box.

[0006] Preferably, the sludge conveying mechanism includes detachable support columns installed on the left and right sides of the curing box. A feeding component is fixedly installed at the end of the support column. A conveying pipe is detachably installed at the upper end of the feeding component. A conveying auger is movably installed inside the conveying pipe. A conveying motor for driving the conveying auger is provided at the lower end of the feeding component. After the worker pours the sludge into the inside of the feeding component, the sludge will enter the inside of the curing box under the action of the conveying auger.

[0007] Preferably, the feeding assembly includes a feeding box fixedly installed on a support column. The feeding box is connected to the inside of the conveying pipe. The conveying motor is fixedly installed at the lower end of the feeding box and is connected to the conveying auger. After the worker pours the sludge into the inside of the feeding box, it will directly enter the inside of the conveying pipe.

[0008] Preferably, the water removal component includes a mounting block fixedly connected to the movable slider. A return spring is fixedly connected to the upper end of the movable slider, and a pressing plate is fixedly installed at the lower end of the mounting block. The lower surface of the pressing plate is serrated. When the pressing plate moves downward, it presses the sludge on the conveyor belt, thereby squeezing out the water inside the sludge.

[0009] Preferably, the transmission assembly includes a driven wheel that is drivenly connected to the conveying cylinder, a driving wheel that is drivenly connected to the rear end of the movable shaft, and a transmission belt that is provided between the driving wheel and the driven wheel. When the movable shaft rotates under the action of the drive motor, it will cause the conveying cylinder to rotate synchronously through cooperation with the transmission assembly.

[0010] Preferably, the upper surface of the mounting plate is provided with a rectangular groove, which is connected to the interior of the sewage storage box. The conveyor belt is located below the discharge port of the conveying pipe. After the sludge is discharged through the upper end of the conveying pipe, it will fall onto the conveyor belt. When the sludge is pressed, the water inside will fall downward into the interior of the sewage storage box.

[0011] Preferably, the curing and shaping mechanism includes a receiving straight plate movably installed inside the curing chamber. A liquid storage tank is provided at the bottom of the inner cavity of the curing chamber. A piston assembly is movably installed inside the liquid storage tank. Drainage vertical pipes are connected to the left and right sides of the lower end of the liquid storage tank. A spray nozzle is fixedly installed at the upper end of the drainage vertical pipe. An installation plate is movably installed at the upper end of the liquid storage tank. An elastic telescopic component is fixedly connected to the lower end of the installation plate. A vertical round rod is fixedly installed at the upper end of the installation plate. The vertical round rod extends above the receiving straight plate. When the receiving straight plate moves downward, it causes the piston assembly to move vertically downward. When the piston assembly moves downward, it causes the sludge curing agent inside the liquid storage tank to enter the interior of the drainage vertical pipe.

[0012] Preferably, the piston assembly includes a pusher plug slidably connected inside the liquid storage tank. A vertical push rod is fixedly installed at the upper end of the pusher plug, extending to the top of the liquid storage tank. When the receiving plate moves downward, it causes the vertical push rod to move downward, and when the vertical push rod moves downward, it causes the pusher plug to move downward synchronously.

[0013] Preferably, the elastic telescopic component includes a telescopic push rod fixedly installed on the upper end of the liquid storage cylinder. A buffer spring is movably sleeved on the outside of the telescopic push rod. The upper end of the telescopic push rod is fixedly connected to the mounting plate. In use, the mounting plate will reciprocate under the action of the telescopic push rod. When the mounting plate moves up and down, it will cause multiple vertical cylinders to move synchronously.

[0014] By employing the above technical solution, the present invention provides a silt drying device for river dredging, which has at least the following beneficial effects:

[0015] 1. This invention, by setting up a pressing and dewatering mechanism, utilizes the cooperation between the dewatering component and the pressing protrusion to automatically squeeze the sludge during the sludge transportation process, thereby squeezing out the water inside the sludge. This not only reduces the weight of the sludge, making it easier to transport and transfer later, but also reduces the amount of solidifying agent used to a certain extent, thus avoiding waste of resources.

[0016] 2. By setting up a press-to-extract water mechanism, the present invention can automatically collect the squeezed-out sewage by utilizing the cooperation between the press plate and the sewage storage box, thus preventing the sewage from dripping everywhere and causing damage to the surrounding environment. At the same time, it can also prevent sewage with irritating odor from affecting the health of workers to a certain extent.

[0017] 3. By setting up a curing and shaping mechanism, the present invention utilizes the cooperation between the receiving plate and the piston assembly. The downward movement distance of the piston assembly is proportional to the amount of sludge on the receiving plate, thereby realizing the automatic quantitative addition of curing agent and effectively avoiding waste of curing agent.

[0018] 4. By setting up a curing and shaping mechanism, the present invention utilizes the cooperation between the elastic telescopic component and the vertical round rod to create multiple circular channels inside the sludge during the downward movement of the receiving plate, thereby accelerating the mixing of the curing agent and the sludge and effectively improving the sludge curing rate.

[0019] 5. By setting up a sludge conveying mechanism, the present invention can automatically and quantitatively convey sludge into the solidification box by utilizing the cooperation between the conveying auger and the feeding component. This not only ensures a reasonable ratio between the amount of sludge and the amount of solidification agent, but also effectively reduces the labor intensity of the workers. Moreover, the solidification box can rotate freely, which greatly improves the device's passability in narrow environments.

[0020] 6. In this invention, there are two sets of sludge conveying mechanisms, which are symmetrically distributed on the left and right sides of the solidification box. This enables double-sided feeding, greatly improving the sludge feeding rate. Moreover, when one set of sludge conveying mechanisms malfunctions and needs to be repaired, the other set can continue to be used. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] according to Figure 1 , Figure 2 as well as Figure 3 As shown, a silt drying device for river dredging includes a movable base 1, with movable rollers 2 at the lower end of the movable base 1, and a curing box 3 movably mounted on the upper end of the movable base 1. Silt conveying mechanisms 4 are provided on both the left and right sides of the curing box 3, and a pressing and dewatering mechanism 5 is provided at the upper end of the curing box 3. A curing and shaping mechanism 6 is provided inside the curing box 3. During river dredging, the silt conveying mechanism 4 will transport the silt into the interior of the curing box 3. During the transportation process, the pressing and dewatering mechanism 5 will press the silt to remove excess water.

[0033] Specifically, the sludge conveying mechanism 4 includes support columns 401 that are detachably installed on the left and right sides of the curing box 3. A feeding assembly 402 is fixedly installed at the end of the support column 401. A conveying pipe 403 is detachably installed at the upper end of the feeding assembly 402. A conveying auger 404 is movably installed inside the conveying pipe 403. A conveying motor 405 for driving the conveying auger 404 is provided at the lower end of the feeding assembly 402. After the worker pours the sludge into the inside of the feeding assembly 402, the sludge will enter the inside of the curing box 3 under the action of the conveying auger 404.

[0034] More specifically, the feeding assembly 402 includes a feeding box fixedly installed on the support column 401. The feeding box is connected to the inside of the conveying pipe 403. The conveying motor 405 is fixedly installed at the lower end of the feeding box and is connected to the conveying auger 404. After the workers pour the sludge into the inside of the feeding box, it will directly enter the inside of the conveying pipe 403.

[0035] In this embodiment, when in use, the staff will push the device to the designated position on the riverbank. During the transfer, the curing box 3 can rotate freely. Therefore, when the device passes through a narrow riverbank, the staff can adjust the lateral width of the device by rotating the curing box 3, thereby greatly improving the device's road-passing performance.

[0036] Upon reaching the designated location, the staff will first pour the sludge into the inside of the feed box, and then manually turn on the power of the device. Next, the sludge inside the feed box will enter the inside of the conveying pipe 403 and be conveyed upward under the action of the conveying auger 404. There is no need for the staff to manually convey it, saving time and effort.

[0037] This embodiment, by setting up a sludge conveying mechanism 4, utilizes the cooperation between the conveying auger 404 and the feeding component 402 to automatically and quantitatively convey sludge into the solidification box 3. This ensures a reasonable ratio between the amount of sludge and the amount of solidified material, while also effectively reducing the labor intensity of the workers. Furthermore, the solidification box 3 can rotate freely, greatly improving the device's passability in confined spaces.

[0038] Example 2

[0039] according to Figures 1-5As shown, based on Embodiment 1, the pressing dewatering mechanism 5 includes mounting square plates 501 symmetrically installed on the left and right sides of the curing box 3. A sewage storage box 502 is detachably installed at the lower end of the mounting square plate 501, and a conveying cylinder 503 is movably installed at the upper end of the mounting square plate 501. A conveying mesh belt 504 is arranged between the two conveying cylinders 503. Vertical slide rails 505 are fixedly installed on both the front and rear sides of the mounting square plate 501. A movable slider 506 is movably installed inside the vertical slide rail 505. A dewatering component 507 is fixedly installed on the movable slider 506. An installation platform 508 is fixedly installed on the side of the vertical slide rail 505. A movable rotating shaft 509 is movably mounted on the mounting platform 508. A pressing protrusion 511 is fixedly sleeved on the outside of the movable rotating shaft 509. A drive motor 510 for driving the movable rotating shaft 509 is fixedly mounted on the mounting platform 508. A transmission assembly 512 is provided between the movable rotating shaft 509 and the conveying cylinder 503. Material feeding scrapers 513 are movably mounted on the upper ends of the left and right sides of the curing box 3. The material feeding scrapers 513 are in contact with the outer surface of the conveying mesh belt 504. When the drive motor 510 runs, it will cause the conveying cylinder 503 to rotate through the transmission assembly 512. When the conveying cylinder 503 rotates, it will transport the sludge into the interior of the curing box 3.

[0040] Specifically, the water removal component 507 includes a mounting block fixedly connected to the movable slider 506. A return spring is fixedly connected to the upper end of the movable slider 506, and a pressing plate is fixedly installed at the lower end of the mounting block. The lower surface of the pressing plate is serrated. When the pressing plate moves downward, it presses the sludge on the conveyor belt 504, thereby squeezing out the water inside the sludge.

[0041] Specifically, the transmission assembly 512 includes a driven wheel that is connected to the conveying cylinder 503, and a driving wheel that is connected to the rear end of the movable shaft 509. A transmission belt is provided between the driving wheel and the driven wheel. When the movable shaft 509 rotates under the action of the drive motor 510, it will cause the conveying cylinder 503 to rotate synchronously through the cooperation with the transmission assembly 512.

[0042] Specifically, a rectangular groove is provided on the upper surface of the mounting plate 501. The rectangular groove is connected to the interior of the sewage storage box 502. The conveyor belt 504 is located below the discharge port of the conveying pipe 403. After the sludge is discharged through the upper end of the conveying pipe 403, it will fall onto the conveyor belt 504. When the sludge is pressed, the water inside will fall downward into the interior of the sewage storage box 502.

[0043] In this embodiment, as Figure 2 As shown, after the sludge is discharged outward through the conveying pipe 403, it will fall onto the conveyor belt 504. Next, the movable shaft 509 will rotate at a certain speed under the drive of the drive motor 510. When the movable shaft 509 rotates, it will cause the conveyor belt 504 to move horizontally, thereby realizing the horizontal conveying of the sludge.

[0044] Furthermore, when the movable shaft 509 rotates, it will cause the pressing protrusion 511 to rotate synchronously. During the rotation of the pressing protrusion 511, it will contact the pressing plate and move it downward. Moreover, when the pressing plate disengages from the pressing protrusion 511, the pressing plate will move upward under the action of the return spring, thereby causing the pressing plate to reciprocate in the vertical direction.

[0045] like Figure 4 As shown, after the pressing plate moves downward, it will squeeze the sludge on the conveyor belt 504. During the squeezing process, the water inside the sludge will be squeezed out, which can effectively reduce the water content inside the sludge. Moreover, the squeezed water will fall downward into the sewage storage box 502, which can effectively prevent the odorous sewage from affecting the surrounding environment.

[0046] Subsequently, the pressed sludge will fall into the solidification box 3 under the action of the feed scraper 513, thus completing the feeding process.

[0047] This embodiment, by setting up a pressing and dewatering mechanism 5, utilizes the cooperation between the dewatering component 507 and the pressing protrusion 511 to automatically squeeze the sludge during the sludge transportation process, squeezing out the water inside the sludge. This reduces the weight of the sludge, facilitating subsequent transportation and transfer, and also reduces the amount of solidifying agent used to a certain extent, avoiding resource waste. In addition, by setting up a pressing and dewatering mechanism 5, this embodiment, through the cooperation between the pressing plate and the sewage storage box 502, can automatically collect the squeezed sewage, preventing the sewage from dripping everywhere and causing damage to the surrounding environment. At the same time, it can also prevent the sewage with irritating odor from affecting the health of workers to a certain extent.

[0048] Example 3

[0049] according to Figure 1 , Figure 6 as well as Figure 7As shown, based on the above embodiment, the curing and shaping mechanism 6 includes a receiving straight plate 601 movably installed inside the curing box 3. A liquid storage tank 602 is provided at the bottom of the inner cavity of the curing box 3. A piston assembly 603 is movably installed inside the liquid storage tank 602. Drainage vertical pipes 604 are connected to the left and right sides of the lower end of the liquid storage tank 602. A spray nozzle 605 is fixedly installed at the upper end of the drainage vertical pipe 604. An mounting plate 606 is movably installed at the upper end of the liquid storage tank 602. An elastic telescopic member 607 is fixedly connected to the lower end of the mounting plate 606. A vertical round rod 608 is fixedly installed at the upper end of the mounting plate 606. The vertical round rod 608 extends above the receiving straight plate 601. When the receiving straight plate 601 moves downward, it will cause the piston assembly 603 to move vertically downward. When the piston assembly 603 moves downward, it will cause the sludge curing agent inside the liquid storage tank 602 to enter the interior of the drainage vertical pipe 604.

[0050] Specifically, the piston assembly 603 includes a pusher plug that is slidably connected inside the liquid storage tank 602. A vertical push rod is fixedly installed at the upper end of the pusher plug, and the vertical push rod extends to the top of the liquid storage tank 602. When the receiving plate 601 moves downward, it will cause the vertical push rod to move downward, and when the vertical push rod moves downward, it will cause the pusher plug to move downward synchronously.

[0051] Specifically, the elastic telescopic component 607 includes a telescopic push rod fixedly installed on the upper end of the liquid storage cylinder 602. A buffer spring is movably sleeved on the outside of the telescopic push rod. The upper end of the telescopic push rod is fixedly connected to the mounting plate 606. In use, the mounting plate 606 will reciprocate under the action of the telescopic push rod. When the mounting plate 606 moves up and down, it will cause multiple vertical cylinders 608 to move synchronously.

[0052] In this embodiment, as Figure 7 As shown, after being pressed, the sludge enters the solidification box 3 and falls onto the receiving plate 601. As the amount of sludge on the receiving plate 601 increases, the receiving plate 601 will move downward under the gravity of the sludge. When the receiving plate 601 moves downward, it will contact the vertical push rod and make it move downward synchronously.

[0053] When the vertical push rod moves downward, the push plug that is in close contact with the inner wall of the liquid storage tank 602 will move downward, thereby causing the curing agent (diluted according to a certain ratio) inside the liquid storage tank 602 to be sprayed out through the drain vertical pipe 604 and the spray nozzle 605. After the curing agent is sprayed out, it will come into contact with the surface of the sludge.

[0054] Moreover, as the receiving plate 601 moves downward, the mounting plate 606 will reciprocate in the vertical direction under the action of the elastic telescopic member 607. When the mounting plate 606 moves, multiple vertical round rods 608 will move synchronously. During the movement of the vertical round rods 608, multiple circular channels will be formed inside the sludge, so that the curing agent on the surface of the sludge can smoothly enter the interior of the sludge, which can effectively improve the efficiency of sludge curing.

[0055] This embodiment, by setting up a curing and shaping mechanism 6, utilizes the cooperation between the receiving plate 601 and the piston assembly 603. The downward movement distance of the piston assembly 603 is proportional to the amount of sludge on the receiving plate 601, thereby realizing the automatic quantitative addition of the curing agent and effectively avoiding waste of the curing agent. In addition, by setting up a curing and shaping mechanism 6, this embodiment utilizes the cooperation between the elastic telescopic member 607 and the vertical round rod 608. During the downward movement of the receiving plate 601, multiple vertical round rods 608 can puncture multiple circular channels inside the sludge, thereby accelerating the mixing of the curing agent and the sludge and effectively improving the sludge curing rate.

[0056] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
