Description

Technical Field

[0001] The present invention relates to the technical field of dredging equipment, and specifically to a silt dredging equipment for river channels in water conservancy projects. Background Art

[0002] In modern water conservancy projects, river channel dredging is an important measure to maintain the health of rivers and ensure smooth shipping. The selection and application of dredging technologies directly affect the dredging efficiency and environmental impact. At present, the river channel dredging technology is mainly mechanical dredging.

[0003] Mechanical dredging is the most common dredging method. It uses mechanical equipment such as excavators, grab buckets, and suction dredgers to directly dig silt from the river bottom and transfer it to a designated location. Mechanical dredging has high efficiency and is suitable for river channels with large amounts of silt and hard riverbeds. However, mechanical dredging may cause certain damage to the riverbed and affect the surrounding environment. When the silt contains a large amount of organic matter, the viscosity of the silt is very high, and oxidants need to be used to decompose the terminal organic matter in the silt. After treatment, the viscosity of the silt is reduced and it is easier to be removed. However, when the existing chemical spraying device is in use, since the silt sinks to the bottom and the silt coagulates together, the chemical can only react with the silt on the outermost layer, and it is very difficult for the chemical to mix with the inner layer of silt, resulting in low use efficiency of the chemical and a lot of chemicals being wasted.

A driving gear 32 is fixedly connected to the bottom end of the support plate 17. The driving gear 32 is meshed and connected to the inner side of the middle gear ring 29. By starting the first motor 30 to drive the transmission shaft 31 to rotate, and the transmission shaft 31 drives the driving gear 32 to rotate, thereby driving the middle gear ring 29 to rotate, and driving the plurality of guide gears 27 to rotate through the middle gear ring 29.

[0038] A cross plate 45 is formed on one side of the support ring 8. A feed cylinder 46 is rotatably connected to the top of the cross plate 45. A feed hopper 47 is fixedly connected to the top end of the feed cylinder 46. The feed hopper 47 is communicated with the feed cylinder 46. A spray nozzle 48 is fixedly connected to the bottom end of the feed cylinder 46, facilitating the feeding of the medicament from the inside of the feed hopper 47 and discharging the medicament from the spray nozzle 48. A side frame 44 is fixedly connected to one side of the mounting plate 2. The feed cylinder 46 penetrates through the side frame 44 and is rotatably connected with the side frame 44. Chain wheels 49 are fixedly connected to the outer sides of the top end of the feed cylinder 46 and the outer side of the rotating shaft 4. A chain 50 is meshed and connected to the outer sides of the two chain wheels 49, driving the feed cylinder 46 to rotate, driving the feed cylinder 46 and the spray nozzle 48 to rotate, and spraying the medicament out, facilitating the dispersion of the medicament and the mixing of the medicament with the sludge.

[0039] When this solution is in use, the fixed arm 1 is installed on the ship. By traveling on the river channel and loading a storage box filled with chemical reagents on the ship, which chemical reagent to use to treat the sludge is determined according to the sludge pollution situation of the river.

[0040] In the practical application of this solution, first, the fixed arm 1 is installed on the vessel to ensure its stability and reliability. When the vessel is traveling on the river, the fixed arm 1 will play a key role. To deal with the silt pollution in different rivers, a storage tank containing various chemical reagents is loaded on the ship. The selection and use of these chemical reagents are determined according to the specific pollution types of the river silt. For example, for the silt with a high organic matter content, oxidants such as hydrogen peroxide or potassium permanganate are used because they can effectively decompose organic substances, reduce the viscosity of the silt, and thus facilitate subsequent dredging operations. For the silt with severe heavy metal pollution, chelating agents such as EDTA or citric acid are selected. These substances can form stable complexes with heavy metal ions, thereby reducing their activity and toxicity in the environment.

[0041] The second motor 51 is started to drive the rotating shaft 4 to rotate when the vessel travels to the silt accumulation area of the river channel. The rotating shaft 4 drives the inclined block 5 to rotate, and then the inclined block 5 drives the rotating rod 6 to rotate. Due to the inclined setting of the helical gear 11, when the inclined block 5 drives the rotating rod 6 to rotate, the support ball 7 at the bottom of the rotating rod 6 and the through connection sleeve 14 are in a state of rotational swing, and the through connection sleeve 14 drives a plurality of support plates 17 to rotate. When the rotating rod 6 rotates, since the helical gear 11 is meshed and connected with the positioning gear ring 10, the helical gear 11 will rotate itself and drive the rotating rod 6 and the support ball 7 to rotate. Since the support ball 7 moves between the two support limit blocks 9, the support balls 7 on both sides support the support limit blocks 9, keeping the support limit blocks 9 stable and supporting the rotating rod 6. When the rotating rod 6 rotates, it drives the through connection sleeve 14, a plurality of support plates 17, and the top support sleeve 18 to rotate around its own axis while revolving. Then, the first motor 30 is started to drive the transmission shaft 31 to rotate. The transmission shaft 31 drives the driving gear 32 and the intermediate gear ring 29 to rotate. When the intermediate gear ring 29 rotates, it drives a plurality of guide gears 27 to rotate, thereby driving a plurality of rotating sleeves 19 to rotate. When the plurality of rotating sleeves 19 rotate, they drive a plurality of reciprocating lead screws 20 to rotate synchronously. Since the reciprocating lead screws 20 are threadedly connected to the upper support 21, the plurality of reciprocating lead screws 20 will move up and down reciprocally when rotating, driving a plurality of claw plates 22 and stirring claws 23 to move up and down reciprocally. The stirring claws 23 are inserted into the silt and rotated to stir the silt, dispersing the silt and creating pores between the silt particles, facilitating the entry of the reagent into the silt through the pores and improving the mixing effect with the silt. Through the above mechanical movements, the silt dredging equipment can effectively disperse and stir the silt in the river channel, thereby improving the mixing efficiency of the reagent and the silt and achieving the purpose of dredging the river channel silt. This design not only improves the efficiency of the dredging operation but also reduces the interference to the environment, providing strong technical support for the ecological restoration and maintenance of the river channel.

[0042] When multiple rotating sleeves 19 rotate, they drive multiple mixing blades 26 to rotate, causing the multiple mixing blades 26 to form turbulent flow in the water, thereby improving the dispersion effect and mixing effect of the medicament and enhancing the decomposition effect of the medicament on the organic matter in the sludge.

[0043] The discharge pipeline of the storage tank of the medicament corresponding to the type of river channel sludge is communicated with the conveying pipe 43 through a conveying pump, and the conveying pump transports the reagent into the feeding connection sleeve 40, enters the guiding pipe 12 through the feeding hole 13, and passes through the inside of the through connection sleeve 14 and falls into the inside of the supporting sleeve 15. When the medicament accumulates inside the supporting sleeve 15, the reciprocating lead screw 20 drives the lower support 39 to rise, and then the lower support 39 drives the sliding pipe 16 to contract towards the inside of the supporting sleeve 15. When the sliding pipe 16 moves towards the inside of the supporting sleeve 15, due to the presence of the medicament inside the supporting sleeve 15, the pressure when the sliding pipe 16 squeezes the medicament pushes the baffle plate 35 to flip towards the inside of the sliding pipe 16, enabling the medicament to enter the inside of the sliding pipe 16. After entering the inside of the sliding pipe 16, the claw plate 22 drives the sliding pipe 16 to extend out of the inside of the supporting sleeve 15. At the same time, in cooperation with the rotation of the supporting sleeve 15 and the sliding pipe 16, the sliding pipe 16 drives the impeller 38 to rotate, throwing the medicament outwards, thereby fully mixing the medicament with the sludge and ensuring the uniform distribution of the medicament. After the medicament is mixed with the sludge, the chemical properties of the sludge will change, thereby reducing its harm to the environment. Subsequently, the chemically treated sludge will be more easily removed by mechanical devices such as excavators or dredging pumps, thereby achieving the purpose of dredging. The design of this solution takes into account the specific requirements of different river channels. Through flexible chemical reagent selection and precise dosing mechanisms, the efficiency and effect of sludge treatment are improved.

[0044] By putting other medicaments used in combination into the feeding hopper 47, the medicament enters from the barrel 46 and sprays out from the spraying nozzle 48. Since sprockets 49 are fixedly connected to the outer sides of the top of the barrel 46 and the outer side of the rotating shaft 4, and the two sprockets 49 are meshed and connected with a chain 50 on the outer sides, the barrel 46 is driven to rotate, driving the barrel 46 and the spraying nozzle 48 to rotate and sprinkle the medicament, facilitating the dispersion of the medicament and enabling the medicament to be mixed with the sludge. The spraying nozzle 48 can evenly spray the chemical reagent onto the surface of the sludge, ensuring that every part of the sludge can be fully treated. In addition, the mounting plate 2 can also be equipped with an advanced sensor system that can monitor the pH value and redox potential of the sludge in real time. These data are crucial for controlling the dosage of chemical reagents because they can help the operator judge the treatment effect of the sludge and automatically adjust the dosage of chemical reagents according to the actual situation. Such a design not only improves the dredging efficiency but also ensures the environmental protection of the entire treatment process, avoiding the problem of secondary pollution that may be caused by excessive use of chemical reagents. Through this intelligent management, we can ensure that the sludge treatment is both efficient and meets environmental protection requirements, providing strong technical support for the cleaning of river channels and the restoration of the ecosystem.
