Description

Technical Field

[0001] The present invention relates to the technical field of dredging devices, and particularly to an integrated waterborne dredging device and a dredging method. Background Technique

[0002] River dredging is an engineering measure to remove silt, garbage and obstacles at the bottom of the river through mechanical or manual means to restore or enhance the flood discharge, navigation and ecological functions of the river. Its core objectives include ensuring flood control safety, improving shipping conditions, restoring the water ecological environment and optimizing the water resource allocation ability. Modern dredging often combines environmental protection technologies, such as ecological dredging to avoid secondary pollution, and uses intelligent monitoring systems to dynamically evaluate the dredging effect. River dredging projects have comprehensive significance for urban flood control, agricultural irrigation, ecological protection, etc., and are important means for basin management and sustainable development; Rivers are prone to carry garbage and move under the drive of water flow. When these garbage move to low-speed basins such as bends, they are likely to sink to the bottom of the river under the action of gravity, causing siltation at the bottom of the river. And after these garbage are in contact with river water for a long time, they will release harmful substances and cause river water pollution. For this reason, we have proposed an integrated waterborne dredging device and a dredging method. Summary of the Invention

[0006] In a further embodiment, the power assembly is an increasing pump, the input end of which is connected to the diversion pipe, and the output end communicates with the inside of the filter sieve cylinder of the separation assembly.

[0007] In a further embodiment, the auxiliary assembly includes: A component housing, fixed to the bottom of the storage cylinder body; A first gear and a second gear that mesh with each other, rotatably installed inside the component housing; wherein, the first gear is simultaneously connected to the output shaft of the driving motor, and the driving motor is installed on the component housing; A guide wheel, arranged outside the component housing and coaxially connected to the second gear; the input end of the diversion pipe is wound around the guide wheel.

[0008] In a further embodiment, a sieve cylinder hatch is hinged at a designated position on the side wall of the filter sieve cylinder; a cylinder body hatch is hinged at the corresponding position of the storage cylinder body.

[0009] In a further embodiment, the gear assembly includes: A rotating rod, rotatably installed radially inside the storage cylinder body; a U-shaped frame is arranged on the rotating rod; A first bevel gear, installed at the output end of the rotating rod; A second bevel gear and a third bevel gear, respectively installed inside the U-shaped frame; the second bevel gear and the third bevel gear are respectively meshed with the first bevel gear; the second bevel gear is connected to the output shaft of the power source.

[0011] The dredging method based on the integrated water dredging device described above includes the following steps: First, start the environmental protection cutter suction dredger to put the dredging device into working state. Start the booster pump in the power component, and at the same time start the power source of the turning component to make each component start to operate. Also, ensure that the drive motor of the auxiliary component is normally started so that the input end of the drainage pipe is in an adjustable state; The dredging device of the environmental protection cutter suction dredger sucks in the mixture of silt and water at the bottom of the river or lake through the drainage pipe. Under the action of the auxiliary component, the length of the input end of the drainage pipe can be flexibly adjusted according to the actual operation depth and other requirements, so as to better suck the silt at different positions. The sucked mixture is transported through the drainage pipe to the filter screen cylinder of the separation component; Under the action of the turning component, the rotating shaft rotates at the bottom of the filter screen cylinder, driving the connecting rod and the scraper to move together. The scraper continuously turns the mixture of silt and water entering the filter screen cylinder, so that the larger particle impurities and stones in the silt are pushed by the scraper, and part of them enter the storage cylinder body through the connecting hole grooves on the outer wall of the filter screen cylinder, while the relatively finer silt and water remain in the filter screen cylinder, initially realizing the separation of silt and part of the impurities. At the same time, during this process, if there is a blockage in the filter screen cylinder, open the screen cylinder door hinged on the side wall of the filter screen cylinder and the cylinder door at the corresponding position of the storage cylinder body to check and clean and dredge; After preliminary separation, the mixture of silt and water remaining in the filter screen cylinder is pumped to the impurity removal and adjustment platform from the silt discharge port at the bottom of the storage cylinder body through the first pumping system, and the impurities remaining in the storage cylinder body outside the filter screen cylinder can be cleaned, collected and processed at a subsequent appropriate time; After reaching the impurity removal and adjustment platform, it first enters the double-layer drum screen, and through the rotating screening action of the drum screen, further removes the sundries with sizes not meeting the requirements remaining in the silt.

[0012] The present invention has the following beneficial effects: The input end of the drainage pipe of the environmental protection cutter suction dredger of the present invention can achieve length adjustment with the help of the auxiliary component, and can flexibly adjust the suction range according to the actual operation depth of the river or lake and the silt distribution at different positions, ensuring that the mixture of silt and water in each area can be effectively sucked, improving the comprehensiveness and accuracy of the collection of river and lake silt, and laying a good foundation for subsequent treatment.

[0013] First, inside the dredging device of the environmental protection cutter suction dredger, the turning component drives the scraper to turn the mixture entering the filter screen cylinder, and using the structure of the filter screen cylinder and the connecting hole grooves, the preliminary separation of larger particle impurities and relatively finer silt is realized. Then, the double-layer drum screen on the impurity removal and adjustment platform further functions to remove the sundries remaining in the silt that do not meet the requirements, forming a multi-stage separation system, greatly reducing the interference of impurities in the subsequent treatment process, ensuring the smooth progress of the entire treatment process, and improving the treatment efficiency and quality.

[0014] The sieve cylinder hatch and the cylinder hatch are respectively hinged on the filtering sieve cylinder and the storage cylinder body. When there is a situation such as blockage of the filtering sieve cylinder during the preliminary separation process, the hatch can be conveniently and quickly opened for inspection, cleaning and dredging, avoiding equipment shutdown caused by blockage problems, ensuring that the device can operate continuously and stably, and reducing the impact of equipment failures on the treatment work.

[0015] The silt discharge end of the environmental protection cutter suction dredger is connected to the impurity removal and adjustment platform through the first pumping system. The impurity removal and adjustment platform is connected to the dehydration and volume reduction platform through the second pumping system. The drainage outlet of the dehydration and volume reduction platform leads to the tail water treatment platform, and the sludge discharge port of the tail water treatment platform is connected to the input end of the dehydration and volume reduction platform. Through reasonable pumping systems and connection settings between each platform, a complete and orderly treatment process is formed, enabling silt and tail water to flow smoothly in each link, achieving integrated and efficient treatment, and avoiding disconnection problems during the treatment process.

[0016] The sludge discharged from the tail water treatment platform can be recycled to the dehydration and volume reduction platform for further treatment, realizing the recycling of sludge resources and reducing the generation of waste. At the same time, the quality of the treated tail water is effectively improved, and part of it can meet the discharge standards, reducing water resource waste, and to a certain extent improving the overall utilization rate of water resources, which conforms to the concept of environmental protection and resource conservation.

[0017] In the whole device, the design such as the adjustable length of the diversion pipe of the environmental protection cutter suction dredger enables it to operate in river and lake environments with different depths, different geographical conditions and different silt conditions, with strong adaptability. Whether in shallow water areas or deep water areas, it can better play the functions of dredging and treating silt, expanding the applicable range of the device and meeting the needs of various river and lake treatment scenarios.

Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Please refer to Figure 1 , the present invention is an integrated water dredging device, including: an environmental protection cutter suction dredger, a first pumping system is arranged at the silt discharge end of the environmental protection cutter suction dredger, the first pumping system is communicated with a impurity removal and adjustment platform, and the impurity removal and adjustment platform includes a double-layer drum screen and a first adjustment tank; the impurity removal and adjustment platform is also communicated with a dehydration and volume reduction platform through a second pumping system, and the drainage port of the dehydration and volume reduction platform is communicated with a tail water treatment platform. In this embodiment, the tail water treatment platform at least includes: a flow-through biological membrane pool, a zeolite fixed bed and a coagulation sedimentation tank; the sludge discharge port of the tail water treatment platform is connected to the input end of the dehydration and volume reduction platform, and in order to control the discharge amount of the sludge, a valve 19 is arranged at the sludge discharge port 6.

[0028] Furthermore, a sludge resource utilization pretreatment area is added to the dehydration and volume reduction platform. For the dehydrated sludge, according to its subsequent resource utilization direction (such as making ceramsite, used for soil improvement, etc.), corresponding pretreatment operations are carried out, such as adding specific additives for modification treatment to make it more in line with the raw material requirements of resource products, improving the resource conversion rate of the sludge, and realizing the efficient transformation from waste to useful resources.

[0029] The environmental protection cutter suction dredger includes: a hull, and a dredging device arranged on the hull. The dredging device includes: a separation component, a turning component arranged inside the separation component, a power component installed on the top of the separation component, a drainage pipe 3 connected to the power component, and an auxiliary component arranged at the bottom of the separation component; the input end of the drainage pipe 3 is adjustable in length through the auxiliary component, and the output end is communicated with the separation component, and the turning component is used to effectively separate the silt and impurities. Further, the power component is an increasing pump 12, whose input end is connected to the drainage pipe 3 and the output end is communicated with the inside of the filter sieve cylinder 2 of the separation component.

[0030] The input end of the drainage pipe 3 in this embodiment is adjustable in length through the auxiliary component, so that the environmental protection cutter suction dredger can flexibly adjust the suction depth and range according to the silt distribution in different areas at the bottom of rivers and lakes. Whether it is a shallow near-shore area or a deep river or lake center position, it can be accurately reached to ensure that silt everywhere is collected to the maximum extent, avoiding omission, and improving the overall coverage ability of the whole treatment device for collecting river and lake silt.

[0031] The turning component is used to turn the inhaled silt and water mixture inside the separation component. Cooperating with the structure of the separation component itself, it can make the impurities in the silt be effectively separated from the finer silt under the agitation and push of the scraper 11 based on characteristics such as different particle sizes, which helps to reduce the interference caused by impurities in the subsequent treatment process, and ensures that subsequent impurity removal, dehydration, tail water treatment and other links are carried out more efficiently and smoothly, improving the overall treatment effect.

[0032] The auxiliary component and the turning component work together in coordination, enabling the entire dredging process to proceed orderly and stably. For example, the auxiliary component can adjust the length of the drainage pipe 3 as needed to adapt to different working conditions, while the turning component continuously functions to ensure impurity separation, reducing the probability of equipment failure due to poor adaptation to the working environment, extending the service life of the equipment, reducing maintenance costs, and ensuring that the environmental protection cutter suction dredger can participate in the treatment of river and lake silt for a long time and stably.

[0033] Further, referring to Figures 2 to 7 , the separation component includes: a storage cylinder body 1 arranged on the hull, the inside of which is a hollow structure; a filter sieve cylinder 2 of a predetermined size is arranged inside the storage cylinder body 1, the top of the filter sieve cylinder 2 is an open structure and is communicated with the input end of the drainage pipe 3, and the bottom of the filter sieve cylinder 2 is a closed structure; a plurality of connecting hole grooves 4 are opened on the outer wall of the filter sieve cylinder 2; A storage top cover 5 is arranged on the top of the storage cylinder body 1, and a silt discharge port 6 is arranged at the bottom; the silt discharge port 6 is arranged to be connected to the first pumping system.

[0034] A plurality of connected hole grooves 4 are provided on the outer wall of the filter screen cylinder 2. When the mixture of sludge and water enters the filter screen cylinder 2 through the drainage pipe 3, under the action of the flipping assembly, larger particles of impurities can be separated through the connected hole grooves 4 and fall into the external storage cylinder 1, while relatively fine sludge and water remain in the filter screen cylinder 2, thereby achieving the preliminary separation of impurities of different particle sizes and sludge, laying the foundation for subsequent more refined impurity removal treatment, and improving the efficiency of impurity removal in the overall treatment process.

[0035] Considering that some impurity particles are large, blockages are difficult to handle. In a further embodiment, a screen door 17 is hinged at a specified position on the side wall of the filter screen 2; a cylinder door 18 is hinged at a corresponding position of the storage cylinder 1. When blockage occurs in the filter screen 2 due to the accumulation of large particles of impurities, the staff does not need to perform complicated disassembly operations on the entire filter screen 2 or the storage cylinder 1. They only need to open the hinged screen door 17 and the corresponding cylinder door 18 to directly access the blocked part, quickly check the blockage status, and use corresponding tools (such as shovels, hooks, etc.) to clean and dredge the blocked impurities, which greatly shortens the time spent on dealing with blockage problems, improves the efficiency of equipment maintenance and troubleshooting, ensures that the entire dredging device can resume normal operation as soon as possible, and reduces the duration of operation interruption caused by blockage.

[0036] At the same time, in order to increase the filtering efficiency and further prevent clogging, the flipping assembly includes: a power source 7, i.e., a motor, arranged on the separation assembly (storage cylinder 1). It also includes: a gear assembly 8 arranged in the separation assembly and connected to the motor in a transmission manner, a rotating shaft 9 rotatably installed at the bottom of the filter screen cylinder 2, and the top of the rotating shaft 9 is connected to the gear assembly 8 in a transmission manner; at least three groups of connecting rods 10 in the same direction are arranged radially at the top and the bottom of the rotating shaft 9, and a scraper 11 is fixed between every two groups of connecting rods 10 in the same direction.

[0037] Considering the consistency of the sludge, in order to increase stability, the gear assembly 8 includes: The rotating rod 801 is rotatably installed in the storage cylinder 1 in the radial direction; the rotating rod 801 is provided with a U-shaped frame 802; A first bevel gear 803 is mounted on the output end of the rotating rod 801; The second bevel gear 804 and the third bevel gear 805 are respectively installed in the U-shaped frame 802 ; the second bevel gear 804 and the third bevel gear 805 are respectively meshed with the first bevel gear 803 ; the second bevel gear 804 is connected to the output shaft of the power source 7 .

[0038] In another embodiment, the auxiliary component includes: a component housing 13 fixed to the bottom of the storage cylinder 1; a first gear 14 and a second gear 15 rotatably mounted within the component housing 13, with the first gear 14 and the second gear 15 meshing with each other. Among them, the first gear 14 is simultaneously connected to the output shaft of the drive motor, and the drive motor is mounted on the component housing 13; It further includes: a guide wheel 16 provided outside the component housing 13 and coaxially connected to the second gear 15; the input end of the drainage pipe 3 is wound around the guide wheel 16.

[0039] The drive motor drives the first gear 14 to rotate. Since the first gear 14 meshes with the second gear 15, the second gear 15 will rotate accordingly. Also, because the guide wheel 16 is coaxially connected to the second gear 15, the guide wheel 16 will also rotate. The input end of the drainage pipe 3 is wound around the guide wheel 16, and the rotation of the guide wheel 16 can achieve the retraction and extension of the input end of the drainage pipe 3, thereby flexibly adjusting the length of the drainage pipe 3. This enables the environmental protection cutter suction dredger to adapt to river and lake environments of different depths. Whether it is a shallow near-shore area or a deep lake center area, it can accurately suck silt, improving the adaptability of the device to different working conditions and the operation range.

[0040] The drive motor drives the first gear 14 to rotate. Since the first gear 14 meshes with the second gear 15, the second gear 15 will rotate accordingly. Also, because the guide wheel 16 is coaxially connected to the second gear 15, the guide wheel 16 will also rotate. The input end of the drainage pipe 3 is wound around the guide wheel 16, and the rotation of the guide wheel 16 can achieve the retraction and extension of the input end of the drainage pipe 3, thereby flexibly adjusting the length of the drainage pipe 3. This enables the environmental protection cutter suction dredger to adapt to river and lake environments of different depths. Whether it is a shallow near-shore area or a deep lake center area, it can accurately suck silt, improving the adaptability of the device to different working conditions and the operation range.

[0041] Embodiment 2 Based on the integrated water dredging device disclosed in Embodiment 1, this embodiment discloses a dredging method for the integrated water dredging device, including the following steps: First, start the environmental protection cutter suction dredger to put the dredging device into the working state. Start the booster pump in the power component and at the same time start the power source of the turning component to make all components start to operate, and ensure that the drive motor of the auxiliary component is also normally started, so that the input end of the drainage pipe is in an adjustable state; The dredging device of the environmental protection cutter suction dredger sucks the mixture of silt and water at the bottom of the river or lake through the drainage pipe. Under the action of the auxiliary component, the input end of the drainage pipe can be flexibly adjusted in length according to actual operation depth and other requirements, so as to better suck silt at different positions. The sucked mixture is transported through the drainage pipe to the filter sieve cylinder of the separation component; Under the action of the flipping component, the rotating shaft rotates at the bottom of the filter sieve cylinder, driving the connecting rod and the scraper to move together. The scraper continuously flips the mixture of silt and water entering the filter sieve cylinder, so that the larger particle impurities and stones in the silt are pushed by the scraper, and part of them enter the storage cylinder through the connecting hole grooves on the outer wall of the filter sieve cylinder, while the relatively finer silt and water remain in the filter sieve cylinder, initially realizing the separation of silt and some impurities. At the same time, during this process, if there is a blockage in the filter sieve cylinder, open the sieve cylinder hatch hinged on the side wall of the filter sieve cylinder and the cylinder hatch at the corresponding position of the storage cylinder to check and clean and dredge. After the preliminary separation, the mixture of silt and water remaining in the filter sieve cylinder is pumped from the silt discharge port at the bottom of the storage cylinder to the impurity removal and adjustment platform through the first pumping system, while the impurities remaining in the storage cylinder outside the filter sieve cylinder can be cleaned, collected and processed at a subsequent appropriate time. After reaching the impurity removal and adjustment platform, it first enters the double-layer drum screen, and through the rotating screening action of the drum screen, further removes the sundries with sizes not meeting the requirements remaining in the silt.

[0042] In the first adjustment tank, the parameters such as the concentration and water content of the silt are preliminarily adjusted to make it reach a more suitable state for subsequent treatment processes, such as adjusting by adding an appropriate amount of water or precipitating for a certain time.

[0043] Use the second pumping system to pump the silt processed by the impurity removal and adjustment platform from the first adjustment tank to the dehydration and volume reduction platform. In the dehydration and volume reduction platform, the silt is dehydrated through corresponding dehydration equipment to reduce its water content and the volume of the silt, facilitating subsequent further treatment and disposal. The water discharged from the dehydration and volume reduction platform first enters the flow-through biofilm pool. In the biofilm pool, microorganisms attach to a specific carrier to form a biofilm. Pollutants such as organic matter and ammonia nitrogen in the water come into full contact with the microorganisms on the biofilm, and through the metabolic action of the microorganisms, these pollutants are decomposed and transformed into harmless substances, thereby reducing the content of pollutants such as organic matter and ammonia nitrogen in the water. The water treated by the flow-through biofilm pool then flows into the zeolite fixed bed. Zeolite has a large specific surface area and adsorption performance, and can adsorb some pollutants such as heavy metal ions and some small-molecule organic matters that are difficult to be biodegraded remaining in the water, further purifying the water quality.

[0044] The water flowing out of the zeolite fixed bed enters the coagulation sedimentation tank, where appropriate coagulants are added to cause some fine suspended particles and colloids in the water to form larger flocs through the coagulation reaction. Then, they settle to the bottom of the tank by gravity in the sedimentation tank. The clear water on the upper layer can be discharged after reaching the discharge standard (for example, discharged into water bodies such as rivers, lakes, etc.). The sludge deposited at the bottom of the tank is transported to the input end of the dewatering and volume reduction platform through the sludge discharge port and undergoes dewatering and volume reduction and other treatments again together with other sludge to be treated, realizing the cyclic treatment of sludge and the rational utilization of resources.

[0045] Regularly inspect each equipment component of the environmental protection cutter suction dredger, impurity removal and regulation platform, dewatering and volume reduction platform, and tail water treatment platform to check for wear, corrosion, blockage, etc. For example, check the wear condition of the scraper of the turning component of the dredging device and the smoothness of each pipeline.

[0046] According to the inspection results, carry out corresponding cleaning and maintenance work on each equipment. For example, thoroughly clean the filter sieve cylinder, double-layer drum screen, replace severely worn components, and maintain the pump body, etc., to ensure that the entire integrated river and lake water treatment device can operate continuously, stably, and efficiently.

[0047] Through the above complete treatment process, pollutants such as sludge in the river and lake can be cleaned and treated more effectively, and the tail water can be properly treated, realizing the improvement of the river and lake environment and the rational protection and utilization of water resources.

The preferred embodiments do not describe all the details in detail, nor limit the invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present invention, so that those skilled in the art can understand and utilize the present invention well.

The scraper continuously flips the sludge and water mixture entering the filter screen, so that the larger particles of impurities and stones in the sludge are pushed by the scraper, and some of them enter the storage cylinder through the connecting hole grooves on the outer wall of the filter screen, while the relatively fine sludge and water remain in the filter screen, which preliminarily realizes the separation of sludge and some impurities; at the same time, in this process, if there is a blockage in the filter screen, open the screen door hinged on the side wall of the filter screen and the cylinder door at the corresponding position of the storage cylinder to check and clean it; After the initial separation, the sludge and water mixture remaining in the filter screen is pumped from the sludge discharge port at the bottom of the storage cylinder to the impurity removal and adjustment platform through the first pumping system, while the impurities remaining in the storage cylinder outside the filter screen can be cleaned, collected and processed at a suitable time later; After arriving at the impurity removal and adjustment platform, it first enters the double-layer drum screen, and the rotating screening action of the drum screen further removes the remaining impurities in the sludge that do not meet the requirements.
