Description

Technical Field

[0001] The invention relates to the technical field of silt clearing equipment, in particular to silt clearing equipment for a water conservancy project river channel. Background Art

[0002] In modern water conservancy projects, river dredging is a crucial measure for maintaining river health and ensuring smooth navigation. The selection and application of dredging technology directly impacts both dredging efficiency and environmental impact. Currently, mechanical dredging is the primary method used for river dredging.

[0003] Mechanical dredging is the most common method of dredging. It uses mechanical equipment such as excavators, grabs, and suction dredgers to directly excavate silt from the riverbed and transfer it to a designated location. Mechanical dredging is highly efficient and suitable for rivers with large amounts of silt and hard riverbeds. However, mechanical dredging may cause certain damage to the riverbed and have an impact on the surrounding environment. When the silt contains a lot of organic matter, the silt has a high viscosity and an oxidant is needed to decompose the terminal organic matter in the silt. The treated silt has reduced viscosity and is easier to remove. However, when the existing chemical spraying device is used, the silt sinks to the bottom and condenses together. The chemical can only react with the surface silt, while the inner silt is difficult to mix with the chemical, resulting in low chemical use efficiency and a lot of chemical being wasted.

The outer side of the rotating sleeve 19 is fixedly connected to a plurality of mixing blades 26 in an annular array, and the sliders 24 are limited by the slide grooves 25, so that the rotating sleeve 19 drives the reciprocating screw 20 to rotate synchronously when it rotates. The rotating sleeve 19 drives the multiple mixing blades 26 to rotate when it rotates, so that turbulence is formed between the multiple mixing blades 26 to improve the dispersion and mixing effect of the medicine. The outer sides of the multiple rotating sleeves 19 are fixedly connected to the guide gears 27, and the outer side of the support sleeve 15 is fixedly connected to the circular plate 28. The top of the circular plate 28 is rotatably connected to the intermediate gear ring 29. The multiple guide gears 27 are meshed and connected to the outer side of the intermediate gear ring 29 in an annular array. A first motor 30 is fixedly connected to the top of one of the support plates 17. The output end of the first motor 30 is fixedly connected to a transmission shaft 31. The transmission shaft 31 passes through the support plate 17 and is rotatably connected to the support plate 17. The bottom end of the support plate 17 is fixedly connected to a driving gear 32. The driving gear 32 is meshed and connected to the inner side of the intermediate gear ring 29. The transmission shaft 31 is driven to rotate by the first motor 30, and the transmission shaft 31 drives the driving gear 32 to rotate, thereby driving the intermediate gear ring 29 to rotate, and driving the multiple guide gears 27 to rotate through the intermediate gear ring 29.

[0038] A horizontal plate 45 is formed on one side of the support ring 8, and a barrel 46 is rotatably connected to the top of the horizontal plate 45. A feed hopper 47 is fixedly connected to the top of the barrel 46. The feed hopper 47 is communicated with the barrel 46, and a spray nozzle 48 is fixedly connected to the bottom of the barrel 46, so that medicine can be fed from the feed hopper 47 and discharged from the spray nozzle 48. A side frame 44 is fixedly connected to one side of the mounting plate 2, and the barrel 46 passes through the side frame 44 and is rotatably connected to the side frame 44. A sprocket 49 is fixedly connected to the outer side of the top of the barrel 46 and the outer side of the rotating shaft 4. The two sprockets 49 are meshed with a chain 50 on the outside, which drives the barrel 46 and the spray nozzle 48 to rotate and sprinkle the medicine, so as to facilitate the dispersion of the medicine and the mixing of the medicine with the sludge.

[0039] When using this solution, the fixed arm 1 is installed on the ship, and the ship is driven on the river. A storage tank containing chemical reagents is loaded on the ship. The chemical reagent to be used to treat the silt is determined according to the silt pollution situation of the river.

[0040] In the practical application of this solution, the fixed arm 1 is first installed on the ship to ensure that it is stable and reliable. The fixed arm 1 part will play a key role when the ship is traveling on the river. In order to cope with the silt pollution in different rivers, storage tanks containing a variety of chemical reagents will be loaded on the ship. The selection and use of these chemical reagents are determined according to the specific pollution type of the river silt. For example, for silt with a high organic matter content, oxidants such as hydrogen peroxide or potassium permanganate are used because they can effectively decompose organic matter and reduce the viscosity of the silt, thereby facilitating subsequent dredging operations. For silt with more serious heavy metal pollution, chelating agents such as EDTA or citric acid are used. These substances can form stable complexes with heavy metal ions, thereby reducing their activity and toxicity in the environment.

[0041] When the boat reaches the silt accumulation place in the river channel, the second motor 51 is started to drive the rotating shaft 4 to rotate, so that 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 bevel gear 11, when the inclined block 5 drives the rotating rod 6 to rotate, the supporting ball 7 at the bottom of the rotating rod 6 and the middle connecting sleeve 14 rotate and swing, and the middle connecting sleeve 14 drives multiple support plates 17 to rotate. When the rotating rod 6 is circling, since the bevel gear 11 is meshed with the positioning gear ring 10, the bevel gear 11 will rotate and drive the rotating rod 6 and the supporting ball 7 to rotate. Since the supporting ball 7 moves between the two supporting limit blocks 9, the supporting balls 7 on both sides support the supporting limit blocks 9, so that the supporting limit blocks 9 remain stable and support the rotating rod 6. When the rotating rod 6 rotates, it drives the middle connecting sleeve 14 and multiple support plates 17 and the top support sleeve 18 to rotate while revolving, and then the first motor 30 is started The transmission shaft 31 is driven to rotate, and the transmission shaft 31 drives the driving gear 32 and the intermediate ring gear 29 to rotate. When the intermediate ring gear 29 rotates, it will drive multiple guide gears 27 to rotate, thereby driving multiple rotating sleeves 19 to rotate. Through the multiple rotating sleeves 19, the multiple reciprocating screws 20 are driven to rotate synchronously when rotating. Because the reciprocating screws 20 are threadedly connected to the upper bracket 21, the multiple reciprocating screws 20 will reciprocate up and down when rotating, so that the multiple reciprocating screws 20 drive the multiple claw plates 22 and the stirring claws 23 to reciprocate up and down, insert the stirring claws 23 into the silt, and rotate to stir the silt, so that the silt is dispersed and pores appear between the silt, which facilitates the entry of the medicine into the silt from the pores and improves the mixing effect with the silt. Through the above-mentioned mechanical movement, the silt dredging equipment can effectively disperse and stir the silt in the river channel, thereby improving the mixing efficiency of the medicine and the silt, and achieving the purpose of cleaning the river channel silt. This design not only improves the efficiency of dredging operations, but also reduces interference with the environment, providing strong technical support for the ecological restoration and maintenance of the river.

[0042] The multiple rotating sleeves 19 drive the multiple mixing blades 26 to rotate when rotating, so that the multiple mixing blades 26 form turbulence in the water, thereby improving the dispersion and mixing effects of the agent and enhancing the decomposition effect of the agent on organic matter in the sludge.

[0043] The discharge pipe of the storage box of the medicine corresponding to the river silt type is connected to the feeding pipe 43 through the feeding pump, and the feeding pump is used to transfer the reagent into the inside of the feeding connecting sleeve 40, enter the inside of the guide pipe 12 from the feeding hole 13, and pass through the inside of the connecting sleeve 14 and fall into the inside of the support sleeve 15. When the medicine accumulates in the support sleeve 15, the reciprocating screw 20 drives the lower bracket 39 to rise, and then the lower bracket 39 drives the slide pipe 16 to retract into the support sleeve 15. When the slide pipe 16 moves to the support sleeve 15, the medicine is pulled back. When the sleeve 15 moves inside, since there is medicine inside the support sleeve 15, the pressure when the slide tube 16 squeezes the medicine pushes the baffle plate 35 to flip inside the slide tube 16, so that the medicine enters the slide tube 16. After entering the slide tube 16, the claw plate 22 will drive the slide tube 16 to extend out of the support sleeve 15. At the same time, with the rotation of the support sleeve 15 and the slide tube 16, the slide tube 16 drives the impeller 38 to rotate and throw the medicine outward, so as to fully mix the medicine with the sludge and ensure the uniform distribution of the medicine. After the medicine 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 sludge suction pumps, thereby achieving the purpose of dredging. The design of this solution takes into account the specific needs of different river channels, and improves the efficiency and effect of sludge treatment through flexible chemical reagent selection and precise delivery mechanism.

[0044] By adding other reagents for use from the feed hopper 47, the reagents enter the barrel 46 and are sprayed out from the spray nozzle 48. A sprocket 49 is fixedly connected to the outside of the top of the barrel 46 and the outside of the rotating shaft 4. The two sprockets 49 are meshed and connected to the outside of the chain 50, which drives the barrel 46 and drives the barrel 46 and the spray nozzle 48 to rotate, and the reagents are sprinkled out, which facilitates the dispersion of the reagents and the mixing of the reagents with the sludge. The spray nozzle 48 can evenly spray the chemical reagents onto the surface of the sludge to ensure that every part of the sludge can be fully treated. In addition, the mounting plate 2 can also be installed 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 amount of chemical reagents added because they can help operators judge the treatment effect of the sludge and automatically adjust the amount of chemical reagents added according to actual conditions. Such a design not only improves the dredging efficiency, but also ensures the environmental friendliness of the entire treatment process and avoids the secondary pollution problem that may be caused by excessive use of chemical reagents. Through this intelligent management, we can ensure that silt treatment is both efficient and environmentally friendly, providing strong technical support for river cleaning and ecological restoration.
