Description

Technical Field

[0001] The present invention relates to the technical field of river and lake management, and in particular to an ecological and environmentally friendly sludge dehydration and consolidation treatment system for rivers and lakes. Background Art

[0002] Today, as environmental protection and water resources management are increasingly valued, the maintenance of river and lake ecosystems has become a key link in ensuring water quality safety and ecological balance. As an indispensable part of river and lake ecosystems, the scientific treatment and reasonable disposal of sludge are crucial to maintaining the health of rivers and lakes. The traditional river and lake ecological and environmentally friendly sludge dehydration and consolidation treatment system achieves effective treatment of sludge through a series of orderly steps - sludge collection, mud treatment, hard object filtration, flocculation treatment and final extrusion dehydration and consolidation. However, although this process meets the basic needs of sludge treatment to a certain extent, it still exposes some obvious limitations in the actual operation process, especially in the filtration and flocculation links.

[0003] Specifically, the existing treatment system relies on filtering devices to remove hard impurities after converting silt into slurry. However, over time, the filtering devices tend to become clogged due to long-term contact with slurry containing a large amount of impurities, which not only seriously affects the filtering efficiency, but also increases the maintenance cost of the system. What is more difficult is that the traditional cleaning method of filtering devices mostly relies on manual operation, which is not only time-consuming and labor-intensive, but also significantly increases the operating cost. Summary of the invention

This design effectively avoids the problem of traditional filtering devices being blocked due to long-term contact with impurities, reduces the need for manual cleaning, and reduces maintenance costs and operating costs. When the filter assembly is detached from the swing arm, the electromagnet in the vibration mechanism cooperates with the telescopic rod to drive the baffle to move, which not only allows foreign matter accumulated on the filter to fall into the impurity box, but also vibrates and cleans the filter assembly through the vibration block, further improving the cleaning effect and ensuring the stability of the filtering efficiency.

This design ensures the uniform distribution of flocculant in the mud, avoids unnecessary waste, and improves the flocculation effect. The swing arm drives the rotation of the filter assembly not only to filter, but also to promote the mixing of mud and flocculant, greatly speeding up the flocculation process and improving the treatment efficiency.

[0015] 3. The interior of the main body adopts a semicircular curved surface design, combined with the curvature change of the pressing surface, so that the filter assembly can be naturally squeezed into the installation groove during the rotation process, realizing the smooth transition and reset of the filter assembly, ensuring the continuity and stability of the entire processing process. Through the precise coordination of the drive assembly, filtering mechanism, vibration mechanism and other components, the fully automated processing of sludge from collection to dehydration and consolidation is realized, improving the overall processing efficiency.

The outer wall of the sliding rod 241 is provided with a docking block 242 at a position corresponding to the docking bolt 2475. The frame 247 is provided with a filter screen 248.

[0032] By adopting the above technical solution, the mud slowly enters the main body 1 through the feed port 12, the driving assembly 15 drives the fixed shaft 21 to rotate counterclockwise, and the swing arm 23 drives the filter assembly 24 to rotate and filter. The filter assembly 24 rotates to nearly 100 degrees and fits with the partition 112. When it reaches 130 degrees, the spring 1 243 unfolds and pushes the filter assembly 24 to fall to the vibration mechanism 3. The electromagnet 35 is energized to attract the baffle 2473, and the telescopic rod 36 pushes it to move, so that foreign matter falls into the impurity box 14. At the same time, the vibration block 32 vibrates to clean the filter 248, and the spring plate 245 absorbs shock. After cleaning, the electromagnet 35 is de-energized, the spring 2474 drives the baffle 2473 to reset, the filter assembly 24 continues to rotate to a vertical state, the docking bolt 2475 docks with the docking block 242, and the filter assembly 24 is squeezed back to the installation groove 231 due to the pressure surface 111. When the swing arm 23 rotates, the water outlet 212 is connected with the water outlet 221, and the flocculant is evenly transported into the mud through the nozzle 233 to avoid waste. At the same time, the rotation of the swing arm 23 also plays a stirring role to accelerate the mixing speed.

[0033] A water delivery trough 232 is provided on one side of the swing arm 23 close to the discharge port 13, a nozzle 233 is arranged inside the water delivery trough 232, a docking hole 211 is provided on the end of the fixed shaft 21 away from the driving assembly 15, a water outlet hole 212 connected to the docking hole 211 is provided on the position of the circumferential outer surface of the fixed shaft 21 corresponding to the water delivery trough 232, a docking pipe 22 for conveying flocculant is connected to the docking hole 211, a water outlet 221 is provided at the bottom of the docking pipe 22, one end of the docking pipe 22 passes through the top frame 11 and extends to the outside thereof and is fixedly connected to the top frame 11, the water outlet hole 212 provided on the circumferential outer surface of the swing arm 23 is circulated and communicated with the water outlet 221, when the water outlet hole 212 is communicated with the water outlet 221, the flocculant inside the docking pipe 22 passes through the water outlet hole 212 and the water delivery trough 232 to the nozzle 233, and the flocculant is evenly conveyed into the mud through the nozzle 233.

[0034] By adopting the above technical solution, when the fixed shaft 21 drives the swing arm 23 to rotate, the water outlet hole 212 opened on the outer surface of the circumference of the swing arm 23 will be circulated and connected with the water outlet 221. When the water outlet hole 212 is connected with the water outlet 221, the flocculant inside the docking tube 22 will reach the nozzle 233 through the water outlet hole 212 and the water trough 232, and the flocculant will be evenly transported into the mud through the nozzle 233. The direction of the water outlet 221 is such that when the swing arm 23 rotates to enter the mud, it will be connected with the water outlet hole 212, and after the swing arm 23 rotates to discharge the mud, it will be disconnected from the water outlet hole 212 and the water outlet 221, thereby avoiding unnecessary waste of flocculant.

[0035] A slide groove 2471 is formed through the outer wall of one end of the frame 247 away from the docking rod 246, and an installation cavity 2472 is formed inside this end. The slide groove 2471 is connected to the installation cavity 2472, and a baffle 2473 is slidably connected inside the slide groove 2471. The bottom of the baffle 2473 extends into the installation cavity 2472, and a spring 2474 is provided inside the installation cavity 2472. One end of the spring 2474 is connected to the baffle 2473, and the baffle 2473 is made of metal.

[0036] By adopting the above technical solution, the baffle 2473 will be extended to the side close to the feed port 12 due to the push of the spring 2474 in the normal state. During the falling process of the filter assembly 24, foreign matter accumulated on the surface of the filter 248 will also fall due to gravity, and the extended baffle 2473 is used to prevent the foreign matter from falling. When the electromagnet 35 attracts the baffle 2473, the telescopic rod 36 pushes the electromagnet 35 to move into the slide groove 2 33. The movement process of the baffle 2473 can also clean its surface.

[0037] It also includes a vibration mechanism 3, which is provided at the top of the impurity box 14.

[0038] By adopting the above technical solution, when the frame 247 is connected to the vibration mechanism 3, the electromagnet 35 is energized, and the electromagnet 35 will generate magnetic force to attract the baffle 2473. After the electromagnet 35 attracts the baffle 2473, the telescopic rod 36 pushes the electromagnet 35 to move into the second slide groove 33. When the electromagnet 35 moves, it will pull the baffle 2473 to move together. As the baffle 2473 is retracted, the vibration block 32 will drive the filter assembly 24 to vibrate, and the stubborn foreign matter will be cleaned up by the vibration.

One end of the spring 2474 is connected to the baffle 2473, and the baffle 2473 is made of metal.

[0042] The vibration mechanism 3 includes a fixed block 31 fixedly connected to the impurity box 14, a second slide groove 33 is provided at the top of the fixed block 31, a fixed groove 34 is provided inside the second slide groove 33, an electromagnet 35 is slidably connected inside the second slide groove 33, one side of the electromagnet 35 extends to the inside of the fixed groove 34, a telescopic rod 36 is provided inside the fixed groove 34, an output end of the telescopic rod 36 is fixedly connected to the electromagnet 35, and a vibration block 32 is provided at the top of the fixed block 31 near the second slide groove 33.

[0043] by Figure 1 , Figure 3For example, in a normal state, the baffle 2473 will be pushed to the side close to the feed port 12 by the spring 2474. When in use, the mud enters the main body 1 through the feed port 12. The flow rate of the mud entering the main body 1 is slow. After the mud enters the interior, the driving component 15 will drive the mounting shaft fixed shaft 21 to rotate counterclockwise. The rotation of the fixed shaft 21 will drive the filter assembly 24 and other components to rotate through the swing arm 23. The swing arm 23 and the filter assembly 24 are both moved close to the inside of the main body 1. After the filter assembly 24 enters the mud, it filters large particles of hard objects through the filter 248. When the filter assembly 24 rotates counterclockwise from a vertical state to about 100 degrees inside the main body 1, it will separate from one end of the inner wall of the main body 1 and the partition. 112, and the inner wall of the filter assembly 24 is fitted together. When the filter assembly 24 rotates about one hundred and thirty degrees, it will be separated from the partition 112. Then, there is nothing to restrict the filter assembly 24, so the spring 1 243 is also unfolded due to the lack of pressure. The spring 1 243 will push the slide bar 241 outward to the installation slot 231. When the slide bar 241 moves, the filter assembly 24 will be taken away from the installation slot 231. When the filter assembly 24 comes out, it will fall due to gravity, swing and fall around the connection point between the docking rod 1 244 and the slide bar 241, and fall to the bottom of the frame 247 and connect with the vibration mechanism 3. During the falling process of the filter assembly 24, foreign matter accumulated on the surface of the filter 248 will also fall due to gravity, and the extended baffle 2473 is used to prevent foreign matter from falling.

[0044] When the frame 247 is connected to the vibration mechanism 3, the electromagnet 35 is energized, and the electromagnet 35 is energized to generate a magnetic force to attract the baffle 2473. When the electromagnet 35 attracts the baffle 2473, the telescopic rod 36 pushes the electromagnet 35 to move into the second slide groove 33. When the electromagnet 35 moves, it will pull the baffle 2473 to move together. The movement of the baffle 2473 will be used to block the end of the foreign matter from moving into the inside of the slide groove 1 2471. When this section is fully retracted into the slide groove 1 2471, the foreign matter will fall into the impurity box 14 without being blocked. At the same time, the process of the movement of the baffle 2473 can also clean its surface. At the same time, the baffle 2473 is pulled by the electromagnet 35 to fix the filter assembly 24. As the baffle 2473 is retracted, the vibration block 32 will drive the filter assembly 24 to vibrate, and the stubborn foreign matter will be cleaned up by the vibration. The spring plate 245 in the limiting groove 2441 plays a shock-absorbing role to prevent the vibration from being transmitted to other places.

[0045] When the filter 248 is cleaned, the electromagnet 35 is powered off and the baffle 2473 is reset by the spring 2474, and then the driving assembly 15 drives the filter assembly 24 to continue rotating so that the filter assembly 24 is separated from the vibration mechanism 3. After the filter assembly 24 rotates to one hundred and eighty degrees, the filter assembly 24 is in a vertical state again. At the same time, the docking bolt 2475 on the outer wall of the frame 247 will be connected to the docking block 242. Because the curvature of the pressure surface 111 close to the rear end of the main body 1 becomes smaller, the rotation of the filter assembly 24 will be slowly squeezed into the installation groove 231 by the pressure surface 111, and then continue to move along the inner wall of the main body 1 for filtering.

[0046] When the fixed shaft 21 drives the swing arm 23 to rotate, the water outlet hole 212 opened on the outer surface of the swing arm 23 will circulate and communicate with the water outlet 221. When the water outlet hole 212 is connected with the water outlet 221, the flocculant in the butt joint 22 will pass through the water outlet hole 212 and the water delivery trough 232 to the nozzle 233, and the flocculant will be evenly transported into the mud through the nozzle 233. The direction of the water outlet 221 makes the swing arm 23 rotate to the direction of the water outlet 21 when entering the mud. 2 will be connected with it, and after the swing arm 23 rotates to discharge the mud, it will be disconnected from the water outlet 212 and the water outlet 221, so as to avoid unnecessary waste of flocculant. The nozzle 233 is arranged on the side away from the feed inlet 12, so it will not directly impact with the mud and will not be hit by foreign objects, which can play a good protective role. The rotation of the filter assembly 24 driven by the swing arm 23 can play a stirring role, which can greatly accelerate the mixing speed of the flocculant and the mud.

[0047] The filter assembly 24 is slidably connected to the swing arm 23 through the slide rod 241, and is combined with the spring 1 243 to achieve automatic disengagement and resetting, avoiding blockage and reducing maintenance costs. After disengagement, the electromagnet 35 and the telescopic rod 36 of the vibration mechanism 3 drive the baffle 2473 to move, clean the foreign matter on the filter 248, and improve the cleaning effect through the vibration block 32. The water outlet 212 of the fixed shaft 21 cooperates with the water outlet 221 of the docking pipe 22 to spray the flocculant in a cycle to ensure uniform distribution and improve the flocculation effect. The rotation of the swing arm 23 not only filters but also promotes the mixing of mud and flocculant, thereby accelerating the processing efficiency. The semicircular curved surface design of the main body 1 and the curvature change of the pressure surface 111 ensure the smooth transition and resetting of the filter assembly 24, ensuring the continuous and stable process. The precise coordination of the drive assembly 15, the filter mechanism 2, the vibration mechanism 3, etc. realizes the fully automated treatment of sludge and improves the overall efficiency.
