Description

Technical Field

[0001] This application relates to the field of titanium dioxide sedimentation tank cleaning, and in particular to a sedimentation tank that facilitates titanium dioxide cleaning. Background Technology

[0002] Titanium dioxide is an important inorganic chemical pigment, with titanium dioxide as its main component. It has important applications in industries such as coatings, inks, papermaking, plastics and rubber, synthetic fibers, and ceramics.

[0003] In the production process of titanium dioxide, in order to improve the utilization rate and economic benefits of titanium dioxide, the titanium dioxide contained in the washing water is precipitated to separate the water and titanium dioxide, thereby obtaining titanium dioxide.

[0004] However, after titanium dioxide settles and is discharged, it tends to adhere to the inner wall of the settling tank, preventing its removal and thus remaining there. The traditional method involves workers entering the settling tank and using shovels to scrape off the adhering titanium dioxide from the inner wall before collecting and removing it. However, this method, coupled with the generally large area required for settling tanks, significantly reduces the efficiency of cleaning the titanium dioxide from the inner wall. Summary of the Invention

[0005] To address the issue of low cleaning efficiency of titanium dioxide on the inner wall of a sedimentation tank, this application provides a sedimentation tank that facilitates titanium dioxide cleaning.

[0006] This application provides a sedimentation tank for easy cleaning of titanium dioxide, using the following technical solution:

[0007] A sedimentation tank for easy cleaning of titanium dioxide includes: a sedimentation tank body for settling washing water; a cleaning mechanism is provided within the sedimentation tank body; the cleaning mechanism includes: a cleaning component and a traction component; the cleaning component includes: a receiving plate, a rotating plate, a rotating rod, and four scrapers; the traction component is disposed on the sedimentation tank body, and the receiving plate is fixed to the traction component; the rotating plate is rotatably mounted on the receiving plate, and a limiting component is provided between the rotating plate and the receiving plate; the rotating rod is disposed on the rotating plate; the four scrapers are evenly distributed along the circumference of the rotating rod, and any two of the scrapers abut against the inner sidewall of the sedimentation tank body.

[0008] By adopting the above technical solution, the traction component is activated to move circumferentially on the top wall of the sedimentation tank body. The traction support plate drives the rotating rod to move circumferentially inside the sedimentation tank. The scraper on the rotating rod is always in contact with the inner wall of the sedimentation tank body, thereby scraping off the titanium dioxide on the inner wall of the sedimentation tank body to achieve the cleaning effect. It not only has high cleaning efficiency, but can also adapt to sedimentation tanks with different floor areas.

[0009] Optionally, the traction assembly includes a connecting part and a pulling part. The connecting part includes a slider and a sliding rod. The top wall of the sedimentation tank body is provided with an annular groove, and the bottom of the annular groove is provided with a guide groove. The slider is slidably disposed in the annular groove, and the width of the slider is smaller than the width of the annular groove. The receiving plate is fixed to the slider. One end of the sliding rod is fixed to the slider, and the other end is disposed in the guide groove. The pulling part is disposed on the sedimentation tank body and connected to the slider.

[0010] By adopting the above technical solution, the slider can pull the receiving plate to drive the rotating rod to move circumferentially inside the sedimentation tank, thereby enabling the scraper to clean the inner wall of the sedimentation tank body; the sliding rod can guide and limit the slider so that the slider can slide stably in the annular groove and is not prone to deflection.

[0011] Optionally, the pulling part includes: a take-up rod, a release rope, a take-up rope, and a drive motor. The top wall of the sedimentation tank body has a receiving groove that communicates with the annular groove. The take-up rod is rotatably installed in the receiving groove. The drive motor is installed on the sedimentation tank body, and the output end of the drive motor is coaxially fixed with the take-up rod. One end of the release rope is wound around the take-up rod, and the other end is fixed to the slider. One end of the take-up rope is fixed to the take-up rod, and the other end is wrapped around the annular groove and fixed to the side of the slider opposite to the release rope.

[0012] By adopting the above technical solution, the drive motor is started to drive the take-up and release rod to rotate. At this time, the take-up and release rod will take up the take-up rope and release the release rope. During the take-up process, the take-up rope will pull the slider to slide around the circumference of the annular groove. The sliding of the slider will drive the rotating rod to move within the sedimentation tank body. Each time it moves to the inner wall of one side of the sedimentation tank body, two scrapers will abut against the inner wall of the sedimentation tank body, thereby scraping off the titanium dioxide on the inner wall of the sedimentation tank body.

[0013] Optionally, the receiving plate has a through-hole, and the inner side wall of the through-hole has a sliding groove. A sliding plate is provided in the through-hole, and the end of the sliding plate is slidably connected in the sliding groove. The top wall of the sliding plate has a through-hole, and the rotating plate is rotatably installed in the mounting hole. A servo motor is installed on the rotating plate, and the output end of the servo motor is coaxially fixed with the rotating rod.

[0014] By adopting the above technical solution, the slide plate is moved to the end of the clearance tank away from the receiving tank, and then the servo motor is started to drive the rotating rod to rotate. At this time, the four scrapers will act as stirring blades, so as to stir the washing water in the sedimentation tank body, so that the flocculant can be fully mixed with the washing water, thereby improving the sedimentation effect of the washing water.

[0015] Optionally, a locking assembly is provided between the sliding plate and the receiving plate. The locking assembly includes a pull rope, a locking rod, and a locking spring. The inner top walls at both ends of the slide along its length are respectively provided with a first locking hole and a second locking hole for inserting the locking rod. The top wall of the sliding plate is provided with a receiving hole. When cleaning the inner wall of the sedimentation tank body, one end of the locking rod is placed in the receiving hole and the other end is inserted into the first locking hole. The locking spring is fixed between the locking rod and the bottom of the receiving hole. One end of the pull rope is fixed to the locking rod, and the other end passes through the locking spring and extends outward through the sliding plate.

[0016] By adopting the above technical solution, the pull rope is pulled back to the receiving hole, and then the slide is pushed to the end of the clearance groove away from the receiving groove; until the receiving hole and the second locking hole are coaxial, the locking rod is automatically inserted into the second locking hole by the elastic force of the locking spring, thus locking the slide. Therefore, when the servo motor is in working state, the slide is not easy to slide freely in the slide groove due to vibration.

[0017] Optionally, the limiting component includes: an iron rod, a limiting spring, and a magnetic plate. The side wall of the rotating plate is evenly provided with four limiting holes along the circumference. The inner wall of the mounting hole is provided with a placement hole. The end of the clearance groove near the traction component is provided with a through hole. One end of the iron rod is placed in any of the limiting holes, and the other end is placed in the placement hole and extends outward through the sliding plate. When cleaning the inner side wall of the sedimentation tank body, the iron rod passes through the through hole. The limiting spring is sleeved on the iron rod, with one end fixed to the iron rod and the other end fixed to the bottom of the placement hole. The magnetic plate is fixed on the top wall of the four corners of the sedimentation tank body.

[0018] By adopting the above technical solution, when the slider slides in a straight line, the iron rod is always inserted into the limiting hole to limit the rotation plate and the receiving plate, so that the rotation plate and the receiving plate are not easy to rotate relative to each other.

[0019] Optionally, the connecting part further includes: an auxiliary wheel, an auxiliary rod, and an auxiliary spring. The inner sidewall of the annular groove is provided with an auxiliary groove, the sidewall of the slider is provided with an auxiliary hole, one end of the auxiliary rod is disposed in the auxiliary hole, the auxiliary spring is fixed between the auxiliary rod and the bottom of the auxiliary hole, and the auxiliary wheel is rotatably mounted on the auxiliary rod and rolls in the auxiliary groove.

[0020] By adopting the above technical solution, the auxiliary wheel can limit the slider, making it difficult for the slider to move in the vertical direction, thus allowing it to slide stably in the annular groove.

[0021] Optionally, the side wall of the release rod is provided with a first anti-detachment groove and a second anti-detachment groove, the end of the release rope away from the slider is wound around the first anti-detachment groove, and the end of the take-up rope away from the slider is fixed to the inner wall of the second anti-detachment groove.

[0022] By adopting the above technical solution, the first anti-derailment groove and the second anti-derailment groove can prevent the release rope and the winding rope from sliding freely on the release rod, and also make the release rope and the winding rope entangled together.

[0023] Optionally, a first guide rod and a second guide rod are fixedly provided on the inner side wall of the receiving groove, the release rope is wound around the first guide rod, and the winding rope is wound around the second guide rod.

[0024] By adopting the above technical solution, the first guide rod and the second guide rod have the effects of guiding and supporting, so that the winding rope is not easily scraped too much against the bottom of the groove during winding, thereby extending the service life of the winding rope; and the unwinding rope is not easily subjected to a large upward pulling force on the slider during winding.

[0025] Optionally, the bottom walls of the rotating rod and the slider are provided with multiple placement grooves, and the placement grooves are provided with balls, which abut against the inner bottom wall of the sedimentation tank body and the bottom of the annular groove.

[0026] By adopting the above technical solution, the ball bearings on the rotating rod can mainly support the rotating rod, so that the slider can drive the rotating rod to move more easily; secondly, it can reduce the friction between the rotating rod and the inner bottom wall of the sedimentation tank body; the ball bearings on the slider can mainly reduce the friction between the slider and the bottom of the annular groove.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The traction component is activated and moves circumferentially on the top wall of the sedimentation tank body. The traction support plate drives the rotating rod to move circumferentially inside the sedimentation tank. The scraper on the rotating rod is always in contact with the inner wall of the sedimentation tank body, thereby scraping off the titanium dioxide on the inner wall of the sedimentation tank body to achieve a cleaning effect. It is not only highly efficient in cleaning, but also adaptable to sedimentation tanks with different floor areas.

[0029] 2. Move the slide plate to the end of the clearance tank away from the receiving tank, and then start the servo motor to drive the rotating rod to rotate; at this time, the four scrapers will act as stirring blades, which can stir the washing water in the sedimentation tank body so that the flocculant can be fully mixed with the washing water, thereby improving the sedimentation effect of the washing water.

[0030] 3. The ball bearings on the rotating rod mainly support the rotating rod, allowing the slider to move the rotating rod more easily; secondly, they reduce the friction between the rotating rod and the inner bottom wall of the sedimentation tank; the ball bearings on the slider mainly reduce the friction between the slider and the bottom of the annular groove.

[0042] This application provides a sedimentation tank that facilitates the cleaning of titanium dioxide.

[0043] See Figure 1 A sedimentation tank for easy cleaning of titanium dioxide generally includes: a sedimentation tank body 1 for settling washing water. During sedimentation, washing water can be injected into the sedimentation tank body 1 first, then flocculant can be added into the sedimentation tank body 1 and left to stand for a period of time to settle. After sedimentation, water and titanium dioxide can be separated, thereby precipitating out titanium dioxide.

[0044] See Figure 1 The sedimentation tank body 1 is equipped with a cleaning mechanism, which includes a cleaning component 2 and a traction component.

[0045] See Figure 2 and Figure 3The cleaning component 2 includes a receiving plate 21, a rotating plate 22, a rotating rod 23, and four scrapers 24. The traction component is mounted on the top wall of the sedimentation tank body 1. One end of the receiving plate 21 is connected to the traction component, and the other end extends into the upper part of the sedimentation tank body 1. The receiving plate 21 is perpendicular to the side of the sedimentation tank body 1 when the traction component is in its initial position. The rotating plate 22 is rotatably mounted on the receiving plate 21, and a limiting component 7 is provided between the rotating plate 22 and the receiving plate 21. When the traction component moves linearly, the limiting component 7 can limit the rotating plate 22, making it difficult for the rotating plate 22 and the receiving plate 21 to rotate relative to each other. When the traction component moves from one side of the sedimentation tank body 1 to an adjacent side, i.e., when turning, the limiting component 7 no longer limits the rotating plate 22 and the receiving plate 21, so that the receiving plate 21 can rotate 90° relative to each other to achieve the purpose of position adjustment, thereby ensuring that the receiving plate 21 is always perpendicular to the side of the traction component on the sedimentation tank body 1.

[0046] See Figure 3 A rotating rod 23 is mounted on a rotating plate 22 and is vertically positioned inside the sedimentation tank body 1. Four scrapers 24 are evenly distributed along the circumference of the rotating rod 23, with the ends of any two scrapers 24 furthest from the rotating rod 23 abutting against the inner wall of the sedimentation tank body 1. During cleaning, the traction assembly can be activated to move circumferentially on the top wall of the sedimentation tank body 1, thereby tractioning the receiving plate 21 to drive the rotating rod 23 to move circumferentially inside the sedimentation tank. The scrapers 24 on the rotating rod 23 are always in contact with the inner wall of the sedimentation tank body 1, thus scraping off the titanium dioxide powder on the inner walls around the sedimentation tank body 1 to achieve a cleaning effect. This method is not only highly efficient but also adaptable to sedimentation tanks with different floor areas.

[0047] See Figure 4 and Figure 5 The traction assembly includes: a connecting part 3 and a pulling part 4.

[0048] See Figure 4 and Figure 5 The connecting part 3 includes a slider 31 and a sliding rod 32. The top wall of the sedimentation tank body 1 is provided with an annular groove 11 along the circumference. The bottom of the annular groove 11 is provided with a guide groove 12 along the circumference. The slider 31 is slidably disposed in the annular groove 11 and slides along the circumference of the sedimentation tank body 1. The width of the slider 31 is smaller than the width of the annular groove 11 so that when the slider 31 slides from one end of the sedimentation tank body 1 to the adjacent side, the slider 31 is not easily stuck, so that it can turn smoothly.

[0049] See Figure 4 and Figure 5The pulling part 4 is disposed on the top wall of the sedimentation tank body 1 and located at one end of the sedimentation tank body 1 along its length. The pulling part 4 is connected to the slider 31. The receiving plate 21 is fixed to the top wall of the slider 31 at one end near the slider 31. One end of the sliding rod 32 is fixed to the bottom wall of the slider 31, and the other end is disposed in the guide groove 12 and can move within the guide groove 12. The sliding rod 32 can guide and limit the slider 31 so that the slider 31 can slide stably within the annular groove 11 and is not prone to deflection.

[0050] See Figure 6 Specifically, the connecting part 3 further includes: an auxiliary wheel 33, an auxiliary rod 34, and an auxiliary spring 35. Auxiliary grooves 13 are provided on both inner sidewalls of the annular groove 11 and along its circumference. An auxiliary hole 311 is provided on the side of the slider 31 closest to the auxiliary groove 13; in this embodiment, there are two auxiliary holes 311 on one side. One end of the auxiliary rod 34 is disposed within the auxiliary hole 311 and can slide within it, while the other end extends out of the auxiliary hole 311.

[0051] See Figure 6 One end of the auxiliary spring 35 is fixed to the bottom of the auxiliary hole 311, and the other end is fixed to the end wall of the auxiliary rod 34. The auxiliary spring 35 can easily reset the auxiliary rod 34. The auxiliary wheel 33 is rotatably mounted on the end of the auxiliary rod 34 away from the auxiliary spring 35, and the auxiliary wheel 33 rolls in the auxiliary groove 13. When the slider 31 moves from one side of the sedimentation tank body 1 to the adjacent side, since the turning radii of the auxiliary wheels 33 on both sides of the slider 31 are inconsistent, the auxiliary rod 34 can slide in the auxiliary hole 311 through the compression or extension of the auxiliary spring 35 to adjust its length. Thus, the auxiliary wheel 33 can always abut against the bottom of the auxiliary groove 13 so that the slider 31 can turn smoothly. The auxiliary wheel 33 can also limit the slider 31 so that the slider 31 is not easy to move in the vertical direction, thus sliding stably in the annular groove 11.

[0052] See Figure 6 In addition, multiple placement grooves 8 are provided on the bottom wall of the rotating rod 23 and the bottom wall of the slider 31. Ball bearings 81 are placed in the placement grooves 8, and the opening of the placement groove 8 is smaller than the diameter of the ball bearings 81 to prevent them from falling out. The ball bearings 81 abut against the inner bottom wall of the sedimentation tank body 1 and the bottom of the annular groove 11. The ball bearings 81 on the rotating rod 23 primarily support the rotating rod 23, allowing the slider 31 to move the rotating rod 23 more easily; secondly, they reduce the friction between the rotating rod 23 and the inner bottom wall of the sedimentation tank body 1. The ball bearings 81 on the slider 31 primarily reduce the friction between the slider 31 and the bottom of the annular groove 11.

[0053] See Figure 5The pulling part 4 includes a retractable rod 41, a release rope 42, a winding rope 43, and a drive motor 44. A receiving groove 14 is formed on the top wall of one end of the sedimentation tank body 1 along its length. The receiving groove 14 is connected to the annular groove 11, and in this embodiment, the depth of the receiving groove 14 is greater than the depth of the annular groove 11. The retractable rod 41 is rotatably mounted inside the receiving groove 14 and is vertically arranged. The drive motor 44 is fixedly mounted on the top wall of the sedimentation tank body 1 and located above the receiving groove 14. The output end of the drive motor 44 is coaxially fixed with the retractable rod 41.

[0054] See Figure 5 One end of the release rope 42 is wrapped around the take-up rod 41, and the other end is fixed to the side of the slider 31 near the receiving groove 14. One end of the take-up rope 43 is fixed to the take-up rod 41, and the other end is wrapped around the annular groove 11 and fixed to the side of the slider 31 away from the release rope 42. During cleaning, the drive motor 44 is started to drive the take-up rod 41 to rotate. At this time, the take-up rod 41 will take up the take-up rope 43 and release the release rope 42. During the take-up process, the take-up rope 43 will pull the slider 31 to slide around the annular groove 11. The sliding of the slider 31 will drive the rotating rod 23 to move within the sedimentation tank body 1. When it moves to the inner wall of one side of the sedimentation tank body 1, two scrapers 24 will abut against the inner wall of the sedimentation tank body 1, thereby scraping off the titanium dioxide on the inner wall of the sedimentation tank body 1.

[0055] After a single cleaning, if subsequent cleaning is required, the retractable rod 41 can be driven to rotate in the opposite direction, so that the release rope 42 is wound up and the retractable rope 43 is released, thereby achieving the effect of repeated cleaning.

[0056] See Figure 5 Furthermore, the side wall of the take-up lever 41 is provided with a first anti-detachment groove 411 and a second anti-detachment groove 412, with the first anti-detachment groove 411 located above the second anti-detachment groove 412. The end of the release rope 42 away from the slider 31 is wound around the first anti-detachment groove 411, and the end of the take-up rope 43 away from the slider 31 is fixed to the inner wall of the second anti-detachment groove 412. The first anti-detachment groove 411 and the second anti-detachment groove 412 prevent the release rope 42 and the take-up rope 43 from sliding freely on the take-up lever 41, and also make the release rope 42 and the take-up rope 43 entangled together.

[0057] See Figure 5A first guide rod 141 and a second guide rod 142 are fixedly installed on the inner side wall of the receiving groove 14. The first guide rod 141 and the second guide rod 142 are horizontally arranged and located on both sides of the take-up and release rod 41. The end of the release rope 42 away from the slider 31 is wrapped around the bottom of the first guide rod 141, and the end of the take-up rope 43 away from the slider 31 is wrapped around the top of the second guide rod 142. The first guide rod 141 and the second guide rod 142 have the effect of guiding and supporting, so that the take-up rope 43 is not easily scraped too much against the bottom of the annular groove 11 when it is being taken up, thereby extending the service life of the take-up rope 43; the release rope 42 is not likely to exert a large upward pulling force on the slider 31 when it is being taken up.

[0058] See Figure 4 A clearance groove 211 is formed through the top wall of the receiving plate 21 along its length. A sliding groove 212 is formed on the inner sidewalls of both ends of the clearance groove 211 along its width and along its length. A sliding plate 5 is provided within the clearance groove 211. The sliding plate 5 is slidably connected to the sliding groove 212 on both sides near the sliding groove 212, and slides along the length of the sliding groove 212. The initial position of the sliding plate 5 is located at one end of the clearance groove 211 near the receiving groove 14.

[0059] See Figure 4 The top wall of the slide plate 5 has a through-hole 51, and the rotating plate 22 is rotatably installed in the mounting hole 51. A servo motor 53 is installed on the top wall of the rotating plate 22, and in this embodiment, the servo motor 53 has a self-locking function. The output end of the servo motor 53 is coaxially fixed with the rotating rod 23 so as to drive the rotating rod 23 to rotate.

[0060] When cleaning is not required, the slide plate 5 can be moved to the end of the relief groove 211 away from the receiving groove 14, and then the servo motor 53 can be started to drive the rotating rod 23 to rotate. At this time, the four scrapers 24 will act as stirring blades, so as to stir the washing water in the sedimentation tank body 1, so that the flocculant can be fully mixed with the washing water, thereby improving the sedimentation effect of the washing water.

[0061] See 7. Figure 8 and Figure 9 Furthermore, a locking assembly 6 is provided between the sliding plate 5 and the receiving plate 21. The locking assembly 6 includes a pull rope 61, a locking rod 62, and a locking spring 63. The inner top walls at both ends of the slide groove 212 along its length are respectively provided with a first locking hole 2121 and a second locking hole 2122 for inserting the locking rod 62. The top wall at one end of the sliding plate 5 located in the slide groove 212 is provided with a receiving hole 52. One end of the locking rod 62 is located in the receiving hole 52 and can slide within the receiving hole 52. When cleaning the inner wall of the sedimentation tank body 1, the end of the locking rod 62 away from the receiving hole 52 is inserted into the first locking hole 2121.

[0062] See Figure 8 One end of the locking spring 63 is fixed to the bottom of the receiving hole 52, and the other end is fixed to the end wall of the locking rod 62. One end of the pull rope 61 is fixed to the end wall of the locking rod 62 near the locking spring 63, and the other end passes through the locking spring 63 and extends outward through the sliding plate 5.

[0063] When cleaning is not required, first pull the pull rope 61 to pull the locking rod 62 back into the receiving hole 52, and then push the slide plate 5 to the end of the relief groove 211 away from the receiving groove 14; until the receiving hole 52 is coaxial with the second locking hole 2122, the locking rod 62 is automatically inserted into the second locking hole 2122 by the elastic force of the locking spring 63, thus locking the slide plate 5. Therefore, when the servo motor 53 is in working state, the slide plate 5 is not easy to slide freely in the slide groove 212 due to vibration.

[0064] See 4 and Figure 10 The limiting component 7 includes an iron rod 71, a limiting spring 72, and a magnetic plate 73. Four limiting holes 221 are evenly distributed circumferentially on the side wall of the rotating plate 22. A placement hole 511 is formed on the inner wall of the mounting hole 51. A through hole 213 is formed on the inner side wall of the end of the clearance groove 211 closest to the receiving groove 14. One end of the iron rod 71 is positioned within any of the limiting holes 221, and the other end is positioned within the placement hole 511, extending outwards through the sliding plate 5. When cleaning the inner wall of the sedimentation tank body 1, the end of the iron rod 71 furthest from the rotating plate 22 passes through the through hole 213. The limiting spring 72 is sleeved on the end of the iron rod 71 located within the placement hole 511, with one end fixed to the bottom of the placement hole 511 and the other end fixed to the side wall of the iron rod 71. The limiting spring 72 is used to reset the iron rod 71.

[0065] See Figure 4 and Figure 10 In this embodiment, four magnetic plates 73 are provided, and each of the four magnetic plates 73 corresponds to one of the four corners of the sedimentation tank body 1. The magnetic plates 73 are fixed to the top walls of the four corners of the sedimentation tank body 1. In this embodiment, the attraction force of the magnetic plates 73 on the iron rod 71 is greater than the elastic force of the limiting spring 72. The magnetic plates 73 are arc-shaped and located on the outside of the annular groove 11. When the slider 31 slides in a straight line, the iron rod 71 is always inserted into the limiting hole 221 to limit the rotation plate 22 and the receiving plate 21, thereby making it difficult for the rotation plate 22 and the receiving plate 21 to rotate relative to each other.

[0066] When the slider 31 moves from one side of the sedimentation tank body 1 to an adjacent side, i.e., when turning, the end of the iron rod 71 away from the rotating plate 22 will approach the magnet. At this time, the magnet will have a magnetic attraction to the iron rod 71 and attract the iron rod 71 to the magnetic plate 73. Thus, the iron rod 71 will no longer be inserted into the limiting hole 221, i.e., it will no longer limit the rotating plate 22 and the receiving plate 21. Thus, when the slider 31 moves from one side of the sedimentation tank body 1 to an adjacent side, the receiving plate 21 can rotate 90° relative to it to achieve the purpose of position adjustment. After rotating 90°, the iron rod 71 will no longer be in contact with the magnetic plate 73, and through the reset of the limiting spring 72, the iron rod 71 will be inserted into the limiting hole 221 in this state (since the servo motor 53, the rotating rod 23 and the scraper 24 have a certain weight, the rotating plate 22 is not easy to rotate automatically), so that the receiving plate 21 is always perpendicular to the side of the slider 31 on the sedimentation tank body 1.

[0067] The working principle of the sedimentation tank for easy cleaning of titanium dioxide according to this application is as follows: During cleaning, the drive motor 44 is started to drive the take-up rod 41 to rotate; at this time, the take-up rod 41 will take up the take-up rope 43 and release the release rope 42. During the take-up process, the take-up rope 43 will pull the slider 31 to slide around the circumference of the annular groove 11; the sliding of the slider 31 will drive the rotating rod 23 to move inside the sedimentation tank body 1, and every time it moves to the inner side wall of one side of the sedimentation tank body 1, two scrapers 24 will abut against the inner side wall of the sedimentation tank body 1, thereby scraping off the titanium dioxide on the inner side wall of the sedimentation tank body 1.

[0068] After a single cleaning, if subsequent cleaning is required, the retractable rod 41 can be driven to rotate in the opposite direction, so that the release rope 42 is wound up and the retractable rope 43 is released, thereby achieving the effect of repeated cleaning.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
