The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figure 1As shown, this embodiment provides a sediment removal device for an aging tank. The sediment removal device for an aging tank includes a tank body 1, a rotating shaft 2, scraper blades 3, and a drive assembly 4.

[0039] like Figure 1 As shown, the tank body 1 has a cylindrical aging tank 11 with its opening facing upwards. A slag outlet 12 is provided at the bottom of the side wall of the aging tank 11. The upper end of the rotating shaft 2 is mounted on the tank body 1, extending downwards into the aging tank 11. The rotating shaft 2 is radially centered within the aging tank 11. One end of the scraper blade 3 is connected to the lower end of the rotating shaft 2 radially, and the other end of the scraper blade 3 has a sidewall scraping portion 31. The lower end of the scraper blade 3 has a bottom wall scraping portion 32. The drive assembly 4 includes a rotary drive component 41 and a lifting drive component 42. The rotary drive component 41 is driven by the rotating shaft 2 to rotate the shaft 2, and the lifting drive component 42 is driven by the rotating shaft 2 to lift the shaft 2.

[0040] In some embodiments, there is a 2mm-5mm gap between the sidewall scraper 31 and the sidewall of the aging tank 11, which can remove most of the deposits while avoiding friction damage to the sidewall scraper 31 and the sidewall of the aging tank 11.

[0041] In other embodiments, the sidewall scraper 31 slides in contact with the sidewall of the aging tank 11, which is beneficial for cleaning the deposits on the sidewall of the aging tank 11 and has a good cleaning effect.

[0042] like Figure 1 As shown, specifically, the tank body 1 includes a cylindrical tank 13 and a tank cover 14. A rotating shaft 2 is rotatably mounted on the tank cover 14. The circumferential sidewall of the cylindrical tank 13 is the sidewall of the aging tank 11, and the bottom wall of the cylindrical tank 13 is the bottom wall of the aging tank 11. The rotating shaft 2 is located at the axis of the aging tank 11. The scraper blades 3 move in a circular motion under the drive of the rotating shaft 2 to scrape off the deposits on the sidewall or bottom wall of the aging tank 11. The lifting drive component 42 and the rotating drive component 41 can both be mounted on the tank cover 14 and supported by the tank cover 14.

[0043] The sediment removal device for the aging tank provided in this embodiment uses a lifting drive 42 to drive the rotating shaft 2 to rise and fall, so that the side wall scraping part 31 of the scraper blade 3 can correspond to the side wall of the aging tank 11 at different heights, and the bottom wall scraping part 32 of the scraper blade 3 can also contact the bottom wall of the aging tank 11. The rotation drive 41 rotates, driving the rotating shaft 2 to rotate. The bottom wall scraping part 32 of the scraper blade 3 scrapes away the sediment attached to the bottom wall of the aging tank 11, and the side wall scraping part 31 of the scraper blade 3 scrapes away the sediment attached to the side wall of the aging tank 11. The slag outlet 12 is located at the bottom of the side wall of the aging tank 11. Under the action of the scraper blade 3 and / or cleaning liquid, the scraped sediment is discharged from the slag outlet 12, thus cleaning the aging tank 11.

[0044] Optionally, the angle between the front sidewall of the sidewall scraper 31 and the sidewall of the aging tank 11 in the rotation direction is an acute angle. The front sidewall refers to the sidewall of the sidewall scraper 31 located at the front in the rotation direction, and the sidewall located at the rear in the rotation direction is the rear sidewall. On the one hand, the acute angle helps to guide and collect the scraped sediment, allowing it to move in a specific direction. Under the guidance of the sidewall scraper 31, the scraped sediment will move towards the slag outlet 12 or the subsequent conveying path of the scraper blade 3, preventing the slag from accumulating or scattering disorderly near the sidewall of the aging tank 11. On the other hand, the acute angle reduces the resistance of the sediment to the sidewall scraper 31, preventing the scraper blade 3 from being structurally damaged due to excessive resistance.

[0045] In some embodiments, the sidewall scraper 31 has a sheet-like structure. From the center of the aging tank 11 outwards, the sidewall scraper 31 is inclined to the rear side in the rotation direction of the scraper blade 3, so that the angle between its front sidewall and the sidewall of the aging tank 11 is an acute angle.

[0046] In other embodiments, the side wall scraping section 31 can also be arranged perpendicular to the peripheral wall of the aging tank 11, which improves the scraping effect.

[0047] Optionally, the angle between the front sidewall of the bottom wall scraper 32 in the rotation direction and the bottom wall of the aging tank 11 is an acute angle. On the one hand, the acute angle helps to guide and collect the scraped sediment, allowing it to move in a specific direction. Under the guidance of the bottom wall scraper 32, the scraped sediment will move towards the slag outlet 12 or the subsequent conveying path of the scraper blades 3, preventing the slag from scattering disorderly within the aging tank 11. On the other hand, the acute angle reduces the resistance of the sediment to the bottom wall scraper 32, preventing the scraper blades 3 from being structurally damaged due to excessive resistance.

[0048] like Figure 1 As shown, in some embodiments, the bottom wall scraper 32 has a sheet-like structure. From the lower end to the upper end of the bottom wall scraper 32, the bottom wall scraper 32 is inclined to the front side in the rotation direction of the scraper blade 3, so that the angle between its front side wall in the rotation direction and the bottom wall of the aging tank 11 is an acute angle.

[0049] Optionally, the angle α between the sidewall scraper 31 and the sidewall of the aging tank 11 is within the range of 30° ≤ α ≤ 45°; and / or, the angle θ between the bottom wall scraper 32 and the bottom wall of the aging tank 11 is within the range of 30° ≤ θ ≤ 45°. This specific angle range of 30°-45° allows for a better balance between the scraping of sediment by the scraper blades 3 and the force exerted on the scraper blades 3 during rotation. If the angle is less than 30°, the scraper blades 3 cannot effectively scrape up the attached sediment, resulting in poor scraping effect; if the angle is greater than 45°, the scraper blades 3 experience high resistance, resulting in insufficient structural reliability and easy damage. In some embodiments, α or θ can be 33°, 36°, or 40°, etc.

[0050] like Figure 1 As shown, optionally, the scraper blade 3 also includes a main body 33, with the side wall scraping part 31 and the bottom wall scraping part 32 both connected to the main body 33. The main body 33 is perpendicular to the bottom wall of the aging tank 11 and the side wall of the aging tank 11. During the scraping process of the scraper blade 3, the vertical main body 33 can better resist the lateral resistance from the sediment, making the scraper blade 3 less prone to deformation during operation and enhancing the overall structural stability of the scraper blade 3.

[0051] like Figure 1 As shown, in some embodiments, the vertical main body 33, the inclined bottom wall scraper 32, and the inclined side wall scraper 31 are connected as a single unit to form a stable connection structure, which disperses the stress borne by the bottom wall scraper 32 or the side wall scraper 31 during the scraping process. Compared with a single-structure scraper blade 3, this combined structure can better withstand the resistance and friction from the deposits, reduce local wear of the scraper blade 3, and extend its service life.

[0052] like Figure 1 As shown, optionally, two scraper blades 3 are provided, and the two scraper blades 3 are symmetrically arranged about the center of the rotating shaft 2. On the one hand, during rotation, the centrifugal forces generated by the two symmetrically arranged scraper blades 3 can be balanced, effectively reducing the additional stress and vibration on the rotating shaft 2 and other components caused by the imbalance of centrifugal forces. On the other hand, when one scraper blade 3 scrapes the slag from a certain area towards the slag outlet 12, the other symmetrical scraper blade 3 can collect the slag from the opposite area and push it to move, making the transfer process of the slag in the aging tank 11 more efficient and realizing the mutual cooperation of the two scraper blades 3 in operation. In other embodiments, the number of scraper blades 3 can also be one, three, or more.

[0053] Optionally, the edges of the sidewall scraping portion 31 and / or the bottom wall scraping portion 32 are provided with a thinning structure. The thinning structure makes the edges of the sidewall scraping portion 31 thinner, like a blade, so that during the rotation of the scraping blade 3, it can more easily cut into the deposits attached to the bottom or sidewall of the aging tank 11, and can more effectively break the adhesion between the deposits and the sidewall or bottom wall, scraping off the deposits, thereby improving the thoroughness of scraping. In some embodiments, the thickness of the thinning structure gradually decreases, forming a blade-shaped thinning structure.

[0054] like Figure 1 As shown, optionally, the sediment removal device for the aging tank also includes a support 5 and a transmission sleeve 43. The support 5 is mounted on the tank body 1, the transmission sleeve 43 is rotatably mounted on the support 5, the upper end of the rotating shaft 2 is slidably inserted into the transmission sleeve 43 and keyed to the transmission sleeve 43, the rotating shaft 2 is driven by the lifting drive component 42, and the transmission sleeve 43 is driven by the rotation drive component 41. The transmission sleeve 43 is rotatably mounted on the support 5 and is only responsible for transmitting the power of the rotation drive component 41, driving the rotating shaft 2 to rotate via the key connection; while the upper end of the rotating shaft 2 is slidably inserted into the transmission sleeve 43 and driven by the lifting drive component 42, realizing the lifting action of the rotating shaft 2 under the drive of the lifting drive component 42.

[0055] In this embodiment, the upper end of the rotating shaft 2 is slidably inserted into the transmission sleeve 43 and is keyed to the transmission sleeve 43. The key serves to interfere with and restrict rotation. One of the outer wall of the rotating shaft 2 and the inner wall of the transmission sleeve 43 is provided with a key, and the other with a vertical groove. The key is slidably disposed in the groove. Through the key connection, the rotating shaft 2 can slide along the axis of the transmission sleeve 43, but cannot rotate around the axis of the transmission sleeve 43.

[0056] like Figure 1 As shown, specifically, the support 5 is connected to the center of the tank cover 14 by flange bolts. The transmission sleeve 43 is coaxially arranged with the rotating shaft 2. The transmission sleeve 43 is rotatably connected to the center of the support 5 by bearings. The rotating shaft 2 passes through the lower end of the support 5 and extends into the transmission sleeve 43. The rotation drive component 41 is fixed on the tank cover 14 and located on one radial side of the transmission sleeve 43, and is connected to the transmission sleeve 43 in a transmission manner. The lifting drive component 42 is bolted to the support 5, located below the transmission sleeve 43, and maintains a distance from the transmission sleeve 43 to form a lifting space.

[0057] like Figure 1As shown, optionally, the lifting drive component 42 includes a lifting sleeve 44, which is fitted over the rotating shaft 2 and connected to the rotating shaft 2 via a thrust roller bearing. The lifting sleeve 44 is only responsible for providing lifting power, while the thrust roller bearing, while transmitting axial force, forms a relatively flexible and stable connection between the lifting sleeve 44 and the rotating shaft 2. This connection method ensures that the rotation of the rotating shaft 2 does not interfere with the rotation driven by the transmission sleeve 43 during lifting; and the rotation of the rotating shaft 2 does not obstruct the lifting of the lifting sleeve 44, ensuring that the rotation and lifting functions of the rotating shaft 2 can be performed simultaneously and smoothly. The thrust roller bearing can effectively withstand axial loads, ensuring the stability of the rotating shaft 2 during the lifting process.

[0058] Specifically, the lifting sleeve 44 is sleeved on the outside of the rotating shaft 2, the inner ring of the thrust roller bearing is fixed to the outer wall of the rotating shaft 2, and the outer ring of the thrust roller bearing is fixed to the inner wall of the lifting sleeve 44. The rotating shaft 2 can rotate relative to the lifting sleeve 44 around its own axis through the thrust roller bearing, but cannot move up and down relative to the lifting sleeve 44 along its own axis.

[0059] In some embodiments, the lifting drive 42 may include a hydraulic telescopic cylinder or an electric cylinder, and the lifting sleeve 44 is fixedly connected to the piston rod of the hydraulic telescopic cylinder or the electric cylinder. At this time, the piston rod of the hydraulic telescopic cylinder or the electric cylinder can extend and retract to drive the lifting sleeve 44 to rise and fall.

[0060] like Figure 1 As shown, optionally, the sediment removal device for the aging tank further includes a transmission belt 45, and the rotary drive component 41 includes a drive motor, which is connected to the transmission sleeve 43 via the transmission belt 45. In some embodiments, the transmission belt 45 is a synchronous toothed belt to avoid slippage during transmission. In other embodiments, the drive motor can also drive the transmission sleeve 43 to rotate via a gear set. In some embodiments, the rotary drive component 41 further includes a reducer, which is connected between the transmission sleeve 43 and the drive motor to reduce the rotational speed and increase the torque, adapting to the cleaning operation of the aging tank 11.

[0061] like Figure 1 As shown, optionally, the sediment removal device for the aging tank also includes a guide pipe 6, which is connected to the slag outlet 12 and extends downwards from the tank body 1. The downwardly extending guide pipe 6, with the help of gravity, has a good gravity flow effect, effectively reducing the residue of sediment in the guide pipe 6 and facilitating the discharge of sediment from the aging tank 11.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
