Description

Technical Field

[0001] This invention relates to the field of sludge conveying technology, and in particular to a sludge cleaning and conveying device. Background Technology

[0002] Sludge is an inevitable byproduct of municipal sewage treatment, chemical production, and river management. It has a complex composition and generally has characteristics such as high viscosity, high water content, fibrous impurities (such as plastic bags, weeds, and cloth strips), and sandy particles, which pose great challenges to the cleaning and transportation process.

[0003] Currently, sludge conveying equipment typically uses screw conveyors, which propel sludge forward through the rotation of helical blades. For example, Chinese Patent CN116424793B discloses a sludge conveying device and method, relating to the field of sludge treatment technology. It includes a sludge storage tank, a transport mechanism, a detection box, and a control module. The transport mechanism is located on one side of the sludge storage tank, and the detection box is fixed to and communicates with the upper side of the sludge storage tank. The control module is electrically connected to the sludge storage tank, the transport mechanism, and the detection box. The transport mechanism includes a conveying component and a pipeline component. The conveying component passes through the sludge storage tank and consists of a first motor, a first rotating shaft, and rotating blades. The pipeline component is fitted onto the conveying component. The pipeline component includes an outer pipeline, an inner pipeline, three support rods, and a drive block. The drive block specifically includes a fixed plate, a sliding rail, pulleys, a driver, and a connecting block. The detection box contains a second motor, a flap, and a portable moisture meter. The invention can roughly measure the moisture content of the internal sludge and feed it back to the control module. Based on the moisture content of the sludge, the control module adjusts the pipe diameter of the pipeline assembly, thereby improving transportation efficiency.

[0004] However, as an inevitable product of municipal sewage treatment, chemical production, and river management, sludge has a complex composition and usually contains fibrous impurities such as plastic bags, weeds, and cloth strips. During the sludge transportation process, the fibrous impurities carried in the sludge are easily entangled on the central first rotating shaft and spiral blades, forming entanglement blockages, causing the motor to overload and shut down. This not only requires manual disassembly and cleaning, which is labor-intensive, but also interrupts the continuous operation process and reduces the efficiency of sludge transportation.

[0028] Example 1: This embodiment of the invention provides a sludge cleaning and conveying device, such as... Figures 1-5 As shown, it includes: a conveying pipe 1, a feeding box 2 connected to the upper surface of one end of the conveying pipe 1, a feeding pipe 3 connected to one side of the feeding box 2, a shredding mechanism installed inside the feeding box 2, the shredding mechanism being used to shred fibrous impurities in the sludge inside the feeding box 2, a discharge pipe 4 connected to the lower surface of the other end of the conveying pipe 1, a first rotating shaft 5 installed inside the conveying pipe 1, the left and right ends of the first rotating shaft 5 being rotatably connected to the inner wall of the conveying pipe 1 respectively, a spiral blade 6 installed outside the first rotating shaft 5, a first motor 7 installed at the end of the conveying pipe 1 away from the discharge pipe 4, and the output end of the first motor 7 being connected to the first rotating shaft 5;

[0029] The shredding mechanism includes a second motor 8, which is mounted on the conveying pipe 1. The output end of the second motor 8 extends into the feed box 2 and is equipped with an impeller body 9. Several blade bodies 10 are mounted on the impeller body 9, and several shredding components are mounted on the outside of the blade bodies 10.

[0030] Several shredding components are arranged at equal intervals along the length of the outer wall of the blade body 10;

[0031] The chopping assembly includes two fixed plates 11, with a second rotating shaft 12 rotatably arranged between the two fixed plates 11. The second rotating shaft 12 is horizontally arranged, and a plurality of annular blades 13 are arranged on the second rotating shaft 12.

[0032] Several annular blades 13 are arranged at equal intervals along the length of the second rotating shaft 12.

[0033] The working principle and beneficial effects of the above technical solution are as follows: Sludge enters the feed box 2 through the feed pipe 3. The second motor 8 and the first motor 7 are started. The output end of the second motor 8 drives the impeller body 9 to rotate inside the feed box 2. The blade body 10 on the impeller body 9 rotates synchronously with it. The centrifugal force of rotation pushes the sludge towards the inner wall of the feed box 2, and at the same time, the sludge is initially broken up. The chopping component on the outside of the blade body 10 rotates together with the blade body 10. The annular blade 13 on the second rotating shaft 12 of the chopping component rotates around its own axis under the action of sludge impact and rotational inertia. Rotating, several annular blades 13 are evenly spaced along the length of the second rotating shaft 12, and several shredding components are evenly spaced along the length of the outer wall of the blade body 10, forming a three-dimensional shredding space. During the process of the sludge being pushed by the impeller body 9 within the feed box 2, it can fully contact the annular blades 13. Whether fibrous impurities are inside or on the surface of the sludge, they can be effectively sheared. Simultaneously, the second rotating shaft 12 is rotatably connected to the fixed plate 11, allowing the annular blades 13 to adaptively rotate with the impact of the sludge, improving the shredding effect and preventing damage to the blades caused by hard impurities. This design is suitable for applications containing... Different types of fibers and sludge with varying moisture contents are sheared and crushed by the rotating annular blade 13, breaking long fibers into short segments to prevent continuous entanglement. The shredded sludge then falls into the conveying pipe 1. The output of the first motor 7 drives the first rotating shaft 5 and the external spiral blades 6 to rotate. The spiral blades 6 propel the sludge along the conveying pipe 1 towards the discharge pipe 4, where it is finally discharged. Because the fiber impurities have been pre-crushed by the shredding component, the short fiber segments are less likely to entangle on the first rotating shaft 5 and spiral blades 6 during subsequent conveying by the spiral blades 6, reducing the frequency of downtime for cleaning and ensuring the continuous and stable operation of the sludge cleaning and conveying device. Furthermore, the sludge pre-treated by the shredding mechanism has a more uniform texture, reducing the resistance of fiber impurities to the spiral blades 6 and improving the sludge conveying efficiency of the sludge cleaning and conveying device. Simultaneously, the reduced entanglement and clogging issues further reduce the overload of the first motor 7 and the jamming of the spiral blades 6, lowering the wear and tear on the first motor 7 and spiral blades 6, reducing maintenance costs, and extending the device's service life.

[0034] Example 2: Based on Example 1 above, a sludge scraping mechanism is provided inside the conveying pipe 1. The sludge scraping mechanism includes several annular scrapers 14. The annular scrapers 14 are located outside the spiral blades 6. The several annular scrapers 14 are equally spaced along the axis of the first rotating shaft 5. The outer periphery of the annular scrapers 14 is slidably connected to the inner wall of the conveying pipe 1. Adjacent annular scrapers 14 are connected by a fixed rod 15. A driving mechanism is provided on the conveying pipe 1. The driving mechanism is used to drive the annular scrapers 14 to slide back and forth inside the conveying pipe 1.

[0035] The annular scraper 14 has a through hole 16 at its center. The through hole 16 is frustoconical in shape. The diameter of the through hole 16 at the end closer to the first motor 7 is larger than the diameter of the through hole 16 at the end farther away from the first motor 7.

[0036] A positioning plate 17 is provided on the outer side of the end of the conveying pipe 1 away from the first motor 7. Two first sliding holes are symmetrically arranged in the upper and lower parts of the annular scraper 14. A positioning shaft 18 is provided in the first sliding hole. One end of the positioning shaft 18 is fixedly connected to the inner wall of the end of the conveying pipe 1 close to the first motor 7. The other end of the positioning shaft 18 extends to the outside of the conveying pipe 1 and is fixedly connected to the side wall of the positioning plate 17. The annular scraper 14 is slidably connected to the positioning shaft 18 in the left and right through the first sliding hole.

[0037] The working principle and beneficial effects of the above technical solution are as follows: During the sludge conveying process of the spiral blade 6, the drive mechanism is activated, which drives the annular scraper 14 to reciprocate left and right along the positioning shaft 18. The positioning shaft 18 is fixed to the conveying pipe 1 through the positioning plate 17, providing stable guidance for the annular scraper 14. Adjacent annular scrapers 14 are connected by a fixing rod 15, which can ensure synchronous movement and avoid the deviation of a single scraper. The annular scraper 14 has a frustum-shaped through hole 16 in the center, and its diameter at the end closer to the first motor 7 is larger than the diameter at the end farther away. This structure will not interfere with the rotation of the spiral blade 6, ensuring the sludge conveying effect. At the same time, the outer periphery of the annular scraper 14 slides and fits against the inner wall of the conveying pipe 1, and during the reciprocating motion, it synchronously scrapes off the sludge hanging on the inner wall of the pipe, which has the following advantages: When the annular scraper 14 slides from right to left, the left end of the annular scraper 14 can scoop up the sludge attached to the inner wall of the conveying pipe 1. The scooped-up sludge moves towards the discharge pipe 4 along with the mainstream sludge pushed by the spiral blade 6, while the other part of the sludge slides to the right along the inner wall of the through hole 16. When the annular scraper 14 slides from left to right, the scooped-up sludge is pushed by the right side plane of the annular scraper 14 and finally discharged through the discharge pipe 4 along with the mainstream sludge. The annular scraper 14, the fixing rod 15 and other components have a simple structure, are easy to disassemble and assemble, and can be quickly replaced. At the same time, by scraping off the sludge attached to the inner wall by the annular scraper 14, the inner wall of the conveying pipe 1 can be self-cleaned, reducing the frequency of manual disassembly and cleaning, shortening the operation and maintenance time, and reducing labor costs.

[0038] Example 3: Based on Example 2, the drive mechanism includes a third motor 19, with a third rotating shaft 20 at the output end of the third motor 19. A rotating rod 21 is located at the front end of the third rotating shaft 20, perpendicular to the third rotating shaft 20. A fourth rotating shaft 22 is located at the end of the rotating rod 21 away from the third rotating shaft 20, parallel to the third rotating shaft 20. The rear end of the fourth rotating shaft 22 is rotatably connected to the front side wall of the rotating rod 21. A connecting rod 23 is located at the front end of the fourth rotating shaft 22, hinged to the side wall of the drive block 24 at the end of the connecting rod 23 away from the fourth rotating shaft 22. The bottom wall of the drive block 24 is slidably connected to the upper surface of the conveying pipe 1. A drive rod 25 is provided at one end away from the connecting rod 23. A drive plate 26 is provided at the other end of the drive rod 25 away from the drive block 24. The drive plate 26 is perpendicular to the drive rod 25 and is located between the positioning plate 17 and the conveying pipe 1. A second sliding hole is provided in the drive plate 26. The drive plate 26 is slidably connected to the positioning shaft 18 through the second sliding hole. A push rod 27 is provided on the side of the drive plate 26 near the conveying pipe 1. The push rod 27 is horizontally set. A third sliding hole is provided at one end of the conveying pipe 1. One end of the push rod 27 passes through the third sliding hole and is fixedly connected to the upper position of the annular scraper 14. The outer wall of the push rod 27 is slidably connected to the inner wall of the third sliding hole.

[0039] The working principle and beneficial effects of the above technical solution are as follows: After the sludge is pre-treated by the crushing mechanism in the feed box 2, it enters the conveying pipe 1 and is pushed and conveyed by the spiral blades 6. At the same time, the third motor 19 is started. The output end of the third motor 19 drives the third rotating shaft 20 to rotate. The rotating rod 21, which is perpendicular to the third rotating shaft 20, moves in a circular motion with the third rotating shaft 20. When the rotating rod 21 moves in a circular motion, it drives the connecting rod 23 to move in a push-pull reciprocating motion through the fourth rotating shaft 22. The end of the connecting rod 23 away from the fourth rotating shaft 22 is hinged to the driving block 24. The bottom wall of the driving block 24 slides in contact with the upper surface of the conveying pipe 1. Under the push-pull action of the connecting rod 23, the driving block 24 moves left and right along the upper surface of the conveying pipe 1. The drive block 24 drives the drive plate 26 to reciprocate synchronously via the drive rod 25. The drive plate 26 is slidably connected to the positioning shaft 18 through the second sliding hole. The positioning shaft 18 provides stable guidance for the drive plate 26 to avoid movement deviation. The push rod 27 on the drive plate 26 passes through the third sliding hole of the conveying pipe 1 and is fixedly connected to the annular scraper 14 at the upper position. When the drive plate 26 slides back and forth, the push rod 27 drives the annular scraper 14 to reciprocate synchronously along the positioning shaft 18. The annular scraper 14 scrapes off the sludge attached to the inner wall of the conveying pipe 1 during the movement. The scraped sludge is discharged from the discharge pipe 4 along with the mainstream sludge, thereby achieving self-cleaning of the inner wall of the conveying pipe 1.

[0040] Example 4: Based on Example 3, a cavity 28 is provided inside the first rotating shaft 5. A fourth sliding hole is provided at the center of the end of the conveying pipe 1 near the drive plate 26, and the fourth sliding hole communicates with the cavity 28. A sliding column 29 is slidably arranged inside the fourth sliding hole. One end of the sliding column 29 is fixedly connected to the side wall of the drive plate 26, and the other end of the sliding column 29 extends into the cavity 28 and is provided with a plurality of drive platforms 30. The drive platforms 30 are frustum-shaped, and the diameter of the end of the drive platform 30 near the first motor 7 is larger than the diameter of the end of the drive platform 30 away from the first motor 7. A plurality of mounting holes 31 are provided at equal intervals along the axial direction of the first rotating shaft 5 on the outer wall of the first rotating shaft 5. Mounting hole 31 communicates with cavity 28 through fifth sliding hole. Mounting hole 31 is located at the conveying gap of spiral blade 6. Drive table 30 corresponds to mounting hole 31 one by one. Cutting block 32 is slidably arranged in mounting hole 31. Cutting blade is arranged on the side of cutting block 32 away from mounting hole 31. Sliding rod 33 is arranged on the side of cutting block 32 close to mounting hole 31. One end of sliding rod 33 passes through fifth sliding hole and is provided with ball 34. Sliding rod 33 is slidably connected to fifth sliding hole. Return spring 35 is sleeved on the outside of sliding rod 33. One end of return spring 35 is connected to inner wall of cavity 28. The other end of return spring 35 is connected to sliding rod 33.

[0041] The working principle and beneficial effects of the above technical solution are as follows: When the third motor 19 drives the drive plate 26 to reciprocate left and right, the drive plate 26 synchronously drives the sliding column 29 to slide left and right in the fourth sliding hole. Several frustum-shaped drive platforms 30 on the sliding column 29 move left and right synchronously in the cavity 28 of the first rotating shaft 5. The drive platform 30 is frustum-shaped, with the large end of the drive platform 30 facing the first motor 7 and the small end of the drive platform 30 facing the discharge pipe 4. As the drive platform 30 moves left and right, the side wall of the drive platform 30 and the ball 34 at the end of the sliding rod 33 are squeezed together. When the drive platform 30 moves towards the discharge pipe 4, the outer wall of the drive platform 30 contacts the ball 34 and gradually pushes the sliding rod 33. The spring 35 is stretched outward, and the sliding rod 33 drives the cutting block 32 to extend outward from the mounting hole 31. The cutting blade on the cutting block 32 protrudes from the surface of the first rotating shaft 5 and enters the conveying gap between the spiral blades 6. The extended cutting blade rotates at high speed with the first rotating shaft 5, performing secondary radial cutting on the fibers and filamentous impurities that are not completely cut in the gap between the spiral blades 6, preventing the fibers from wrapping around the shaft. When the drive table 30 moves back towards the first motor 7, the squeezing force of the drive table 30 on the ball bearing 34 disappears, the return spring 35 rebounds, and the sliding rod 33 and the cutting block 32 retract into the mounting hole 31. The cutting blade is retracted, which will not affect the normal conveying of sludge. Figure 1As shown, when the cutting blade extends, it is located on the upper side of the first rotating shaft 5. At this time, there is less sludge on the cutting blade, which does not easily affect the upward extension of the cutting blade. When the mounting hole 31 is rotated downward, the cutting blade has retracted into the mounting hole 31. At this time, it is in a position with more sludge. The retraction of the cutting blade will not affect the sludge conveying and can also reduce the impact of sludge on the cutting blade, thus extending the service life of the cutting blade. Multiple cutting blocks 32 are evenly distributed along the axis of the first rotating shaft 5, corresponding to the entire conveying gap of the spiral blade 6. During the sludge conveying process, the periodic extension and retraction of the cutting blocks 32 can continuously cut and clean the fiber impurities wrapped around the first rotating shaft 5, reducing the fiber impurities wrapped around the first rotating shaft 5. This is especially suitable for long-distance conveying pipelines 1, and greatly improves the continuous operation capability of the sludge cleaning and conveying device.
