Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment, and in particular to an easy-to-clean lifting component for sludge treatment. Background Technology

[0002] Sludge treatment is an indispensable part of wastewater treatment. Its main purpose is to reduce harmful substances in sludge, reduce its volume, recover resources, and ensure the safety and environmental friendliness of final disposal. Sludge typically contains large amounts of water, organic matter, heavy metals, and other pollutants. If discharged directly into the environment without proper treatment, it can cause serious pollution to soil, water bodies, and air.

[0003] A wastewater sludge treatment device, disclosed in CN219010127U, includes a sedimentation tank and a filter tank on the right side of the sedimentation tank. A partition with an opening at the bottom is installed between the filter tank and the sedimentation tank. By installing a filter tank on the right side of the sedimentation tank, the sludge-water entering the sedimentation tank settles and is then pushed into the filter tank by a conveying screw shaft. As the sludge-water continuously enters the sedimentation tank, when the liquid level exceeds the solid-liquid separation screen, the water is filtered into the upper part of the filter tank and discharged through a discharge pipe. The sludge is retained in the lower part of the filter tank. The continuously rotating conveying screw shaft pushes the sludge collected in the filter tank into a connecting pipe. During this continuous pushing process, the sludge enters a lifting cylinder. The rotation of the lifting screw shaft lifts the sludge from the bottom to the top of the lifting cylinder. During this process, excess water gradually settles, and the sludge is discharged from the discharge pipe at the top of the lifting cylinder, completing the sludge dewatering treatment.

[0004] Due to the inherent design features of the sludge treatment device in the aforementioned technology, the inner cavity of the lifting cylinder is difficult to clean, and sludge easily adheres to the inner wall. This not only affects the transmission efficiency but may also clog the equipment, leading to a reduction in treatment efficiency. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes an easy-to-clean sludge lifting assembly. A drive motor rotates a screw shaft, and the spiral blades on the outer circumference of the screw shaft effectively lift and transport sludge. Simultaneously, the screw shaft drives a connected bushing to rotate synchronously. The bushing, through a linkage assembly, drives a drive shaft in a reciprocating motion, which in turn drives a scraper to scrape off the sludge adhering to the inner wall of the lifting cylinder. The reciprocating motion of the scraper and the conveying action of the screw shaft work together to not only help dewater the sludge during the lifting process and reduce its specific gravity, but also effectively improve the sludge lifting efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an easy-to-clean sludge treatment lifting assembly, including a lifting cylinder, a feed inlet disposed at one end of the upper end face of the lifting cylinder, a discharge outlet disposed at the other end of the lower end face of the lifting cylinder, a spiral shaft disposed in the inner cavity of the lifting cylinder, spiral blades uniformly disposed on the outer periphery of the spiral shaft, a drive motor for driving the spiral shaft, a scraper disposed in the inner cavity of the lifting cylinder, and a drive assembly for driving the scraper. The spiral shaft passes through the lifting cylinder and is connected to the output shaft of the drive motor.

[0007] The drive assembly includes a drive shaft connected to the scraper, a bushing connected to the spiral shaft, and a linkage assembly disposed between the drive shaft and the bushing.

[0008] By adopting the above technical solution, the drive motor rotates the screw shaft, and the spiral blades on the outer periphery of the screw shaft can effectively lift and transport sludge. Simultaneously, the screw shaft drives the connected bushing to rotate synchronously. The bushing, through a linkage assembly, drives the drive shaft to reciprocate, thereby driving the scraper to scrape off the sludge adhering to the inner wall of the lifting cylinder. The reciprocating motion of the scraper and the conveying action of the screw shaft work together to not only help dewater the sludge during the lifting process and reduce its specific gravity, but also effectively improve the sludge lifting efficiency.

[0009] As a preferred embodiment, bearing seats are respectively provided at the connection points between the two ends of the spiral shaft and the lifting cylinder, and sealed bearings are provided at the connection points between the bearing seats and the spiral shaft.

[0010] By adopting the above technical solution, both ends of the screw shaft are connected to the lifting cylinder through bearing seats. Sealed bearings are mounted on the bearing seats, which not only ensures stable rotation of the screw shaft within the lifting cylinder but also effectively prevents material leakage. When the drive motor drives the screw shaft to rotate, the screw shaft rotates around the sealed bearings. The presence of the sealed bearings ensures that the internal space of the lifting cylinder remains sealed during the operation of the screw shaft, thereby guaranteeing the sealing and efficiency of material transportation.

[0011] As a preferred embodiment, an electrical control box is provided at one end of the lifting cylinder, and the mounting base of the drive motor is fixedly connected to the inner cavity of the electrical control box.

[0012] By adopting the above technical solution, an electrical control box is installed at one end of the lifting cylinder. This control box not only facilitates the fixed installation of the drive motor, but also ensures the high efficiency and stability of the drive motor during operation through its stable structure. The control box and the drive motor mounting base are firmly connected, ensuring that the motor's performance is not disturbed during the lifting process.

[0013] As a preferred embodiment, the scraper is of the same length as the lifting cylinder, and the outer side of the scraper is set with the curvature of the lifting cylinder.

[0014] By adopting the above technical solution, the scraper and the lifting cylinder are set to the same length, and the outer side of the scraper matches the curvature of the inner wall of the lifting cylinder. This design can ensure that the scraper is in close contact with the inner wall of the lifting cylinder, thereby effectively scraping off the sludge adhering to the inner wall.

[0015] As a preferred embodiment, the linkage assembly includes a driven gear connected to the drive shaft, a driving gear meshing with the driven gear, a mounting shaft connected to the driving gear, a second connecting lug fixedly connected to the driving gear, a first connecting lug fixedly connected to the bushing, and a connecting rod disposed between the first connecting lug and the second connecting lug. The drive shaft is connected to the driven gear via a spline, and the mounting shaft is also connected to the driving gear via a spline. The other ends of the drive shaft and the mounting shaft are rotatably connected to the mounting plate, and the mounting plate is fixedly connected to the inner cavity of the electrical control box.

[0016] By adopting the above technical solution, the spline structure facilitates the connection of the driven gear to the drive shaft and the mounting shaft to the driving gear, and the other end of the drive shaft and the mounting shaft are installed by the mounting plate.

[0017] As a preferred embodiment, one end of the connecting rod is rotatably connected to the first connecting lug via a connecting pin, and the other end of the connecting rod is also connected to the second connecting lug via a connecting pin.

[0018] By adopting the above technical solution, the rotational motion of the drive shaft can be accurately transmitted to the driven gear through the spline connection between the drive shaft and the driven gear, and the spline connection between the mounting shaft and the driving gear. When the screw shaft rotates inside the lifting cylinder, the bushing rotates accordingly, causing the first connecting lug plate fixedly connected to it to move synchronously. At the same time, the second connecting lug plate is fixedly connected to the driven gear that meshes with the driving and driven gears. One end of the connecting rod is rotatably connected to the first connecting lug plate through a connecting pin, and the other end is connected to the second connecting lug plate, forming a series of linkage structures. Therefore, as the bushing rotates, the first connecting lug plate, the connecting rod, and the second connecting lug plate work together to enable the driving gear to perform forward and reverse rotation, which in turn drives the driven gear to perform forward and reverse rotation. The scraper plate is fixed to the driven gear. Driven by the driving gear, the scraper plate can perform forward and reverse rotation inside the lifting cylinder, thereby effectively removing the sludge adhering to the inner wall of the cylinder. This process combines the reciprocating motion of the scraper with the conveying action of the screw shaft, which not only helps to improve the dewatering and deweighting of sludge during the process, but also effectively improves the overall lifting efficiency of sludge.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model;

[0020] Driven by a motor, the spiral shaft rotates, and the spiral blades on the outer periphery of the spiral shaft can effectively lift and transport sludge. At the same time, the spiral shaft drives the bushing connected to it to rotate synchronously. The bushing drives the drive shaft to reciprocate in both directions through the linkage component, thereby driving the scraper to scrape off the sludge adhering to the inner wall of the lifting cylinder.

[0021] The spiral shaft drives the bushing to rotate, and the bushing drives the drive shaft to reciprocate through the linkage component. The drive shaft drives the scraper to scrape off the sludge adhering to the inner wall of the lifting cylinder, thereby achieving efficient and low-density sludge lifting, thus improving lifting efficiency and reducing sludge adhesion, and ensuring the smooth progress of the lifting process.

[0034] like Figures 1 to 4 As shown, an easy-to-clean sludge treatment lifting assembly includes a lifting cylinder 1, a feed inlet 21 located at one end of the upper surface of the lifting cylinder 1, a discharge outlet 22 located at the other end of the lower surface of the lifting cylinder 1, a spiral shaft 3 located in the inner cavity of the lifting cylinder 1, spiral blades 31 evenly arranged on the outer periphery of the spiral shaft 3, and a drive motor 8 for driving the spiral shaft 3. Sludge enters the inner cavity of the lifting cylinder 1 through the feed inlet 21. When the drive motor 8 is started, its output shaft drives the spiral shaft 3 to rotate, and the spiral blades 31 rotate accordingly, lifting the sludge and conveying it to the discharge outlet 22.

[0035] In one embodiment, please refer to [specific example]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The spiral shaft 3 has bearing seats at both ends where it connects to the lifting cylinder 1, and sealed bearings are installed at the connection points between the bearing seats and the spiral shaft 3. The spiral shaft 3 is connected to the lifting cylinder 1 at both ends via the bearing seats, and the sealed bearings are mounted on the bearing seats. This not only ensures stable rotation of the spiral shaft 3 within the lifting cylinder 1 but also effectively prevents material leakage. When the drive motor 8 drives the spiral shaft 3 to rotate, the spiral shaft 3 rotates around the sealed bearings. The presence of the sealed bearings ensures that the internal space of the lifting cylinder 1 remains sealed during the operation of the spiral shaft 3, thereby guaranteeing the sealing and efficiency of material transportation.

[0036] In one embodiment, please refer to [specific example]. Figure 2 , Figure 3 and Figure 4 An electrical control box 7 is installed at one end of the lifting cylinder 1. The mounting base of the drive motor 8 is fixedly connected to the inner cavity of the electrical control box 7. This electrical control box 7 not only facilitates the fixed installation of the drive motor 8, but also ensures the high efficiency and stability of the drive motor 8 during operation through its stable structure. The secure connection between the electrical control box 7 and the mounting base of the drive motor 8 ensures that the motor's performance is not disturbed during the lifting process.

[0037] In one embodiment, please refer to [specific example]. Figure 2 , Figure 3 and Figure 4 The scraper 4 is installed in the inner cavity of the lifting cylinder 1 and the drive assembly for driving the scraper 4 is provided. The spiral shaft 3 passes through the lifting cylinder 1 and is connected to the output shaft of the drive motor 8.

[0038] In one embodiment, please refer to [specific example]. Figure 4 The drive assembly includes a drive shaft 41 connected to the scraper 4, a bushing 51 connected to the spiral shaft 3, and a linkage assembly disposed between the drive shaft 41 and the bushing 51. In this invention, the spiral shaft 3 drives the bushing 51 to rotate, and the bushing 51 drives the drive shaft 41 to perform forward and reverse reciprocating motion through the linkage assembly. The drive shaft 41 drives the scraper 4 to scrape off the sludge adhering to the inner wall of the lifting cylinder 1, thereby achieving efficient and low-density sludge lifting, thus improving lifting efficiency and reducing sludge adhesion, and ensuring the smooth progress of the lifting process.

[0039] In one embodiment, please refer to [specific example]. Figure 3 and Figure 4 The scraper 4 is set to the same length as the lifting cylinder 1, and the outer side of the scraper 4 matches the curvature of the lifting cylinder 1. This design ensures that the scraper 4 is in close contact with the inner wall of the lifting cylinder 1, effectively scraping away the sludge adhering to the inner wall. Its working principle is that when sludge accumulates inside the lifting cylinder 1, the scraper 4, as the lifting cylinder 1 rotates or moves, forms a sealed contact with the inner wall of the lifting cylinder 1. Utilizing its shape and size advantages, it tightly adheres to and scrapes away the sludge on the inner wall. Because the outer contour of the scraper 4 matches the curvature of the inner wall of the lifting cylinder 1, the scraper 4 can move more precisely along the inner wall, effectively removing sludge deposits of various shapes and locations, ensuring the cleanliness of the inside of the lifting cylinder 1, and improving work efficiency and operational performance.

[0040] In one embodiment, please refer to [specific example]. Figure 2 , Figure 3 and Figure 4The linkage assembly includes a driven gear 53 connected to the drive shaft 41, a driving gear 52 meshing with the driven gear 53, a mounting shaft 522 connected to the driving gear 52, a second connecting lug 521 fixedly connected to the driving gear 52, a first connecting lug 511 fixedly connected to the bushing 51, and a connecting rod 54 disposed between the first connecting lug 511 and the second connecting lug 521. The drive shaft 41 is connected to the driven gear 53 via a spline, and the mounting shaft 522 is also connected to the driving gear 52 via a spline. The other ends of the drive shaft 41 and the mounting shaft 522 are rotatably connected to the mounting plate 6, respectively. Plate 6 is fixedly connected to the inner cavity of the electrical control box 7. The spline structure facilitates the connection between the driven gear 53 and the drive shaft 41, and between the mounting shaft 522 and the driving gear 52. The other end of the drive shaft 41 and the mounting shaft 522 are installed via the mounting plate 6. One end of the connecting rod 54 is rotatably connected to the first connecting ear plate 511 via a connecting pin, and the other end of the connecting rod 54 is also connected to the second connecting ear plate 521 via a connecting pin. Through the spline connection between the drive shaft 41 and the driven gear 53, and the spline connection between the mounting shaft 522 and the driving gear 52, the rotational motion of the drive shaft 41 can be accurately transmitted to the driven gear 53. When the screw shaft 3 rotates inside the lifting cylinder 1, the bushing 51 rotates accordingly, causing the first connecting ear plate 511, which is fixedly connected to it, to move synchronously. At the same time, the second connecting ear plate 521 is fixedly connected to the driven gear that meshes with the driving gear 52 and the driven gear 53. One end of the connecting rod 54 is rotatably connected to the first connecting ear plate 511 via a connecting pin, and the other end is connected to the second connecting ear plate 521, forming a series of linkage structures. Therefore, as the bushing 51 rotates, the first connecting ear plate 511, the connecting rod 54, and the second connecting ear plate 521 work together to enable the drive gear 52 to rotate in both directions, thereby driving the driven gear 53 to also rotate in both directions. The scraper 4 is fixed to the driven gear 53. Driven by the drive gear 52, the scraper 4 can rotate in both directions inside the lifting cylinder 1, effectively removing the sludge adhering to the lifting cylinder. This process, combining the reciprocating motion of the scraper 4 with the conveying action of the screw shaft 3, not only helps in the dewatering and deweighting of the sludge during the lifting process but also effectively improves the overall lifting efficiency of the sludge.

[0041] In this embodiment, during use, sludge enters the inner cavity of the lifting cylinder 1 through the feed inlet 21. When the drive motor 8 starts, its output shaft drives the screw shaft 3 to rotate, and the screw blades 31 rotate accordingly, lifting and conveying the sludge to the discharge port 22. At the same time, the screw shaft 3 drives the bushing 51 to rotate. As the bushing 51 rotates, the first connecting lug 511, the connecting rod 54, and the second connecting lug 521 work together to enable the drive gear 52 to perform forward and reverse rotation, which in turn drives the driven gear 53 to also perform forward and reverse rotation. The scraper 4 is fixed on the driven gear 53. Driven by the drive gear 52, the scraper 4 can perform forward and reverse rotation inside the lifting cylinder 1, thereby effectively removing the sludge attached to the lifting cylinder. This process, through the combination of the forward and reverse reciprocating motion of the scraper 4 and the conveying action of the screw shaft 3, not only helps to dewater and deweight the sludge during the lifting process, but also effectively improves the overall lifting efficiency of the sludge.

[0042] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
