Description

Technical Field

[0001] This invention belongs to the field of sludge dewatering technology for environmentally friendly dredging, and more specifically, relates to a sludge dewatering device for environmentally friendly dredging. Background Technology

[0002] Environmental dredging is a solution for treating river pollution, aiming to remove polluted sediment from river and lake bodies, eliminate the internal sources of pollution, reduce the release of pollutants from sediment into the water, and combine environmental dredging with ecological restoration. It has the characteristics of environmental dredging—removing pollutants from lakes and creating conditions for the restoration of aquatic ecosystems. Through the close integration of the two, the water environment of shallow rivers and lakes can be improved.

[0003] Environmental dredging is achieved through environmentally friendly slurry suction heads, which remove bottom sediment from rivers and lakes. The advantage of underwater environmental dredging is its targeted nature, which allows for rapid reduction of pollutants.

[0004] Because the working environment is underwater, the ratio of water to pollutants during dredging reaches 10:1 or higher. Current treatment involves using a suction dredger to extract polluted sediment from rivers and lakes, then transferring it to settling ponds for several days or even longer. The limited number of ponds necessitates repeated, long-term treatments, resulting in a lengthy process. Furthermore, the treatment of the settled sludge and surface water in the ponds is ineffective, as water cannot be effectively removed from the sludge, disrupting the settling equilibrium and causing secondary pollution. This increases the cost of sludge dewatering and leads to unsatisfactory treatment results.

[0005] Therefore, it is necessary to provide an environmentally friendly dredging sludge dewatering device to solve the above-mentioned technical problems. Summary of the Invention

[0016] A drive seat is disposed on the floating plate, and a drive cavity is formed inside the drive seat. A through hole communicating with the drive cavity is formed on the side wall of the drive seat.

[0017] Two traction ropes, one end of which is located inside the drive cavity, and the other end is connected to both ends of the fixed plate respectively;

[0018] A transmission assembly, located within the drive cavity, is used to drive the traction rope to extend and retract.

[0019] As a further aspect of the present invention: the transmission assembly includes:

[0020] Two rotating shafts are rotatably mounted within the drive cavity via bearings;

[0021] The rope winding shaft and the first gear are mounted on the rotating shaft. The two traction ropes are respectively wound and connected to the two rope winding shafts at one end inside the drive cavity, and are symmetrical to each other.

[0022] A driving component is disposed within the driving cavity, and the output end of the driving component is provided with a second gear that meshes with both sides of the first gear.

[0023] As a further embodiment of the present invention: both ends of the float are provided with brackets, and guide wheels are rotatably provided on the brackets. The two traction ropes pass through the through hole, are turned by the guide wheels, and are connected to the fixed plate.

[0024] As a further embodiment of the present invention: outer columns are provided on both sides of the bottom of the floating plate, an inner column is slidably inserted inside the outer column, a plurality of fixing holes are provided on the inner column, fastening bolts adapted to the fixing holes are provided on the outer column, and a limit plate is provided at the bottom of the inner column.

[0027] A limiting component is disposed within the connecting seat for fixing the connecting seat to the floating plate.

[0028] As a further aspect of the present invention: the sidewall of the float plate is provided with a plurality of sliding grooves that are slidably adapted to the connecting seat, and the inner wall of the sliding groove is provided with a plurality of limiting holes, the limiting component comprising:

[0029] A linkage cavity is formed within the connecting seat, and a push rod and a limiting block adapted to the limiting hole are movably disposed within the linkage cavity;

[0030] The connecting rod is connected at both ends to the push rod and the limiting block, respectively.

[0031] An elastic element is disposed between the limiting block and the linkage cavity.

[0032] As a further aspect of the present invention: a return pool is also provided inside the regulating pool and connected thereto, and one end of the connecting pipe located in the regulating pool is connected to the return pool.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. In this scheme, the water in the equalization tank will flow along multiple staggered floating plates. The upper layer of clear water on the other side of the equalization tank will be discharged through the clear water pipe. When the water flows in the equalization tank, the mud-water mixture (heavy matter) will settle to the bottom of the tank. The distribution of multiple staggered floating plates can increase the travel distance and time of the water flow in the equalization tank, thereby making the mud-water mixture settle more thoroughly and greatly increasing the sludge thickness and sludge concentration at the bottom of the equalization tank.

[0035] 2. In this solution, a drive mechanism powers a sludge pump to repeatedly extract sludge from the bottom of the equalization tank and discharge it into the homogenization tank. The equalization and homogenization tanks improve the dewatering effect and efficiency of the wastewater mixture, avoiding the current practice of prolonged settling in the tanks. This significantly shortens the treatment period and increases efficiency. Furthermore, the simultaneous flow and settling of water in the equalization tank and the timely extraction of clean water via a mobile sludge pump ensures a more comprehensive treatment process and greatly reduces the risk of secondary pollution. Additionally, the mixing of the chemical water returning from the homogenization tank with the sludge water in the equalization tank extends the contact time of the chemical solution, maximizing its effectiveness and increasing sludge sedimentation in the equalization tank. This significantly improves the sludge dewatering effect and greatly reduces the cost of sludge dewatering.

[0036] 3. In this solution, a limiting plate is installed at the bottom of the float plate to prevent the sludge pump at the bottom of the float plate from accidentally hitting the bottom and being damaged. Furthermore, when the water level in the equalization tank is low, the float plate will be supported by the limiting plate as the water level drops. This not only protects the sludge pump, but also allows the float plate to be used as a reference for changes in the water level in the equalization tank, thereby alerting the staff and enabling them to take timely action. The alerting effect is good and the solution is highly practical.

[0037] 4. In this solution, multiple connecting seats and counterweight floats are installed on the side wall of the float plate. The height of the counterweight floats can be changed along the side wall of the float plate. The height of the float plate in the water can be changed by the counterweight floats, which can change the height between the bottom of the float plate and the bottom of the equalization tank, and adjust the distance between the sludge pump and the bottom of the equalization tank. Therefore, it can be adjusted according to different sludge thicknesses at the bottom of the tank, etc. It has a wide range of applications, is suitable for various situations, and is highly flexible.

[0051] 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.

[0052] Please see Figure 1-4 An environmentally friendly dredging sludge dewatering device includes an equalization tank 1, a homogenization tank 2, and a sludge pump 3. It also includes: a connecting pipe 4 connecting the equalization tank 1 and the homogenization tank 2, with a one-way valve on the connecting pipe 4 to allow water from the homogenization tank 2 to flow unidirectionally into the equalization tank 1; a clear water pipe 5 connecting the equalization tank 1 and the clear water tank; multiple float plates 6 arranged alternately on both sides of the equalization tank 1 to extend the water flow channel within the equalization tank 1, the float plates 6 being able to float up and down with the buoyancy of the water, and the sludge pump 3 being movably mounted on the bottom of the float plates 6; and a drive mechanism 7 mounted on the float plates 6 to drive the sludge pump 3 to move back and forth along the bottom of the float plates 6.

[0053] During use, the environmentally friendly dredging system uses an environmentally friendly suction head to remove bottom sediment from rivers and lakes. The removed sludge and water are then discharged into one side of the regulating tank 1. At this point, the water flows in an "S" shape along multiple staggered floating plates 6. The upper layer of clear water (i.e., light, high-quality water) flowing to the other side of the regulating tank 1 is discharged through the clear water pipe 5. As the water flows in the regulating tank 1, the mud-water mixture (heavy) settles at the bottom of the tank, in the gap between the floating plates 6 and the bottom of the regulating tank 1. The distribution of multiple staggered floating plates 6 increases the travel distance and time of water flow in the regulating tank 1, thereby enabling more and more thorough settling of the mud-water mixture, greatly increasing the thickness and concentration of sludge at the bottom of the regulating tank 1. Simultaneously, the drive mechanism 7 drives the sludge pump 3 to move back and forth along the bottom of the float plate 6. The sludge pump 3 extracts the sludge at the bottom of the equalization tank 1 and pumps it into the homogenization tank 2. This achieves water flow and sedimentation in the equalization tank 1, and discharges clear water while simultaneously removing the sludge from the bottom of the equalization tank 1. The treatment process is smoother, more complete, and more efficient. At the same time, chemicals are added to the homogenization tank 2 to further react, flocculate, and settle the sludge impurities in the water of the sludge-water mixture discharged into the homogenization tank 2, improving the sludge dewatering performance in the homogenization tank 2. After opening the one-way valve of the connecting pipe 4, some of the water in the equalization tank 2 will flow back into the equalization tank 1. The returned water contains chemicals and will mix with the sludge water in the equalization tank 1, flowing together along the float plate 6. By introducing the returned chemical solution into the equalization tank 1, the reaction time of the chemical solution is extended, allowing the sludge water in the equalization tank 1 to react and settle further, fully utilizing the effect of the chemical solution, increasing the amount of sludge sedimentation in the equalization tank 1, and reducing the moisture content of the sludge entering the equalization tank 1 near the tail end. Furthermore, the float plate 6 extends the water flow channel, thereby extending the reaction time of the chemicals in the water and improving the equalization effect of the chemicals. In summary, the setup of equalization tank 1 and homogenization tank 2 improves the dewatering effect and efficiency of wastewater mixtures, avoiding the current need for prolonged settling in the tanks, significantly shortening the treatment period and increasing efficiency. Furthermore, the simultaneous flow and settling of water in equalization tank 1, along with the timely discharge of clean water, is achieved through a mobile sludge pump 3, ensuring a smoother and more comprehensive treatment process and greatly reducing the risk of secondary pollution. Simultaneously, the mixing of the chemical water returned from homogenization tank 2 with the sludge water in equalization tank 1 extends the contact time of the chemical solution, fully utilizing its effectiveness, increasing sludge sedimentation in equalization tank 1, and significantly improving sludge dewatering, thereby greatly reducing the cost of sludge dewatering.

[0054] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 3The equalization tank 1 is also equipped with a return tank 26 connected to it. One end of the connecting pipe 4 is connected to the return tank 26. By setting up the return tank 26 between the equalization tank 2 and the equalization tank 1, some of the chemical solution and water in the equalization tank 2 flow into the return tank 26 through the connecting pipe 4, and then flow from the return tank 26 into the equalization tank 1. The return tank 26 mainly serves as a transition. The water and chemicals entering the return tank 26 from the equalization tank 2 will undergo a more comprehensive reaction, making the chemicals react and be used more evenly. Afterwards, the water from the return tank 26 enters the equalization tank 1 and reacts more comprehensively with the sewage, improving the sludge settling effect.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 4 Multiple positioning posts 8 are installed on the inner wall of the regulating tank 1. Each positioning post 8 has a slot 9 that slides and adapts to a float 6. One end of the float 6 is equipped with a sliding strip 10, and the inner wall of the slot 9 has a groove that adapts to the sliding strip 10. One end of the float 6 is inserted into the slot 9 of the positioning post 8 and moves up and down along the groove via the sliding strip 10, thus restricting the forward, backward, left, and right movements of the float 6. Furthermore, the float 6 can float up and down with the water level in the regulating tank 1, ensuring that the bottom of the float 6 is at a specified distance from the regulating tank 1.

[0056] In this embodiment, preferably, please refer to [reference needed]. Figure 4-5 and Figure 11 The bottom of the float plate 6 is provided with a guide rail 11, and a slide block 12 is slidably mounted on the guide rail 11. The sludge pump 3 is mounted on the bottom of the slide block 12, and a fixing plate 13 is provided on the slide block 12. Ball bearings 29 are rolled on the slide block 12, contacting the guide rail 11. The drive mechanism 7 drives the slide block 12 and the sludge pump 3 to move back and forth along the guide rail 11. By providing ball bearings 29 on the inner wall of the slide block 12 in contact with the guide rail 11, the ball bearings 29 will roll when the slide block 12 moves, which can greatly reduce the friction of the slide block 12, thereby improving the smoothness and stability of the movement of the sludge pump 3 driven by the slide block 12, resulting in good performance.

[0057] In this embodiment, preferably, please refer to [reference needed]. Figure 5 and Figure 7The drive mechanism 7 includes: a drive base 71, mounted on the float 6, with a drive cavity 72 inside the drive base 71 and a through hole 73 on the side wall of the drive base 71 communicating with the drive cavity 72; two traction ropes 74, one end of each rope being located inside the drive cavity 72, and the other end being connected to both ends of the fixed plate 13; and a transmission assembly 75, located inside the drive cavity 72, used to drive the traction ropes 74 to retract and extend. The transmission assembly 75 simultaneously retracts and extends both traction ropes 74, meaning that retracting one traction rope 74 causes the other traction rope 74 to extend. For example, when the left traction rope 74 is tightened, the right traction rope 74 extends simultaneously. This causes the fixed plate 13 and the slide 12 to move to the left along the guide rail 11, thus moving the sludge pump 3 to the left, and vice versa. This allows the sludge pump 3 to move back and forth on the guide rail 11, making it easy to operate and highly practical.

[0058] In this embodiment, preferably, please refer to [reference needed]. Figure 7 The transmission assembly 75 includes: two rotating shafts 751, which are rotatably mounted in the drive cavity 72 via bearings; a rope winding shaft 752 and a first gear 753, which are mounted on the rotating shafts 751; one end of two traction ropes 74 located in the drive cavity 72 are respectively wound and connected to the two rope winding shafts 752, and are symmetrical to each other; and a drive member 754, which is mounted in the drive cavity 72. The output end of the drive member 754 is provided with a second gear 755 that meshes with the first gears 753 on both sides. The drive member 754 in this application is a servo motor.

[0059] When the drive unit 754 is activated, it drives the second gear 755 to rotate. The second gear 755 then simultaneously drives the first gears 753 on both sides to rotate, and the rotation directions of the first gears 753 are the same. The first gears 753 then drive the rope-winding shaft 752 to rotate. Figure 7 From a certain perspective, if the first gear 753 and the rope-winding shaft 752 rotate clockwise, the left traction rope 74 will be wound and tightened, while the right traction rope 74 will be released outwards. Conversely, if the first gear 753 and the rope-winding shaft 752 rotate counterclockwise, the left traction rope 74 will be released outwards, while the right traction rope 74 will be wound and tightened. This allows the traction ropes 74 on both sides to be wound and released, thereby enabling the traction ropes 74 to drive the fixed plate 13, the slide block 12, and the sludge pump 3 to move to the left along the guide rail 11. The operation is simple and ingenious, the action is continuous, and the effect is good.

[0060] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 6Both ends of the float 6 are equipped with brackets 14, and guide wheels 15 are rotatably mounted on the brackets 14. Two traction ropes 74 pass through the through holes 73, are turned by the guide wheels 15, and are then connected to the fixed plate 13. When the traction ropes 74 move the fixed plate 13, they are guided by the guide wheels 15, making the movement more stable and reducing the friction of the traction ropes 74, thus improving their service life.

[0061] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 6 The float plate 6 has outer columns 16 on both sides of its bottom. An inner column 17 is slidably inserted into the outer column 16. Multiple fixing holes 18 are provided on the inner column 17, and fastening bolts 19 that match the fixing holes 18 are provided on the outer column 16. A limit plate 20 is provided at the bottom of the inner column 17. By providing the limit plate 20 at the bottom of the float plate 6, the sludge pump 3 at the bottom of the float plate 6 can be prevented from accidentally hitting the bottom and being damaged, thus protecting the sludge pump 3. Furthermore, when the water level in the equalization tank 1 is low, the float plate 6 will be supported by the limit plate 20 as the water level drops. This not only protects the sludge pump 3 but also allows the float plate 6 to provide a reference for changes in the water level in the equalization tank 1, thus alerting staff and enabling timely intervention. The system offers effective alerts and is highly practical.

[0062] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 8-9 It also includes: a connecting seat 21, which is slidably disposed on the side wall of the float plate 6 and has multiple such seats, and a counterweight float 22 is disposed on the connecting seat 21; and a limiting component 23, which is disposed inside the connecting seat 21 and is used to fix the connecting seat 21 to the float plate 6.

[0063] By setting multiple connecting seats 21 and counterweight floats 22 on the side wall of the float plate 6, and the counterweight floats 22 can change their height along the side wall of the float plate 6, the height at which the float plate 6 floats in the water can be changed, that is, the height between the bottom of the float plate 6 and the bottom of the equalization tank 1 can be changed, which also means that the distance between the sludge pump 3 and the bottom of the equalization tank 1 can be adjusted. Thus, it can be adjusted according to different sludge thicknesses at the bottom of the tank, etc., with a wide range of applications, suitable for various situations, and highly flexible.

[0064] In this embodiment, preferably, please refer to [reference needed]. Figure 8-10The side wall of the float plate 6 is provided with multiple sliding grooves 24 that are slidably adapted to the connecting seat 21. The inner wall of the sliding groove 24 is provided with multiple limiting holes 25. The limiting component 23 includes: a linkage cavity 231, which is opened in the connecting seat 21. A push rod 232 and a limiting block 233 adapted to the limiting hole 25 are movably arranged in the linkage cavity 231; a connecting rod 234, which is connected to the push rod 232 and the limiting block 233 at both ends respectively; and an elastic element 235, which is disposed between the limiting block 233 and the linkage cavity 231. The elastic element 235 in this application is a spring.

[0065] The connecting seat 21 can slide along the sliding groove 24. Before moving, by squeezing the push rod 232, the push rod 232 will drive the limiting block 233 to move through the connecting rod 234. At the same time, the limiting block 233 will compress the elastic element 235, so that the limiting block 233 is completely inserted into the linkage cavity 231. After the connecting seat 21 drives the counterweight float 22 to move to the specified height, the position of the limiting block 233 corresponds to the corresponding limiting hole 25. After releasing the push rod 232, the rebound force of the elastic element 235 will drive the limiting block 233 to move out of the linkage cavity 231. Finally, the limiting block 233 will be inserted into the limiting hole 25 at the corresponding position, thereby fixing the connecting seat 21 at this time, that is, limiting the position of the counterweight float 22. The adjustment operation is convenient, time-saving and labor-saving.

[0066] The sliding groove 24 is provided with a positioning groove 27, and the connecting seat 21 is provided with a positioning block 28 that is slidably adapted to the positioning groove 27. When the connecting seat 21 slides along the sliding groove 24, it will drive the positioning block 28 of the connecting seat 21 to slide along the positioning groove 27. This can limit the front-back and left-right directions of the connecting seat 21 and the counterweight float 22, thereby positioning the connecting seat 21 and improving the smoothness and stability of the movement of the connecting seat 21.
