Description

Technical Field

[0001] This utility model belongs to the field of settling tank technology, specifically referring to a settling tank that is easy to settle and clean. Background Technology

[0002] In the field of mineral processing, settling tanks are crucial equipment, widely used in the sedimentation of tailings after ore sorting, the concentration of concentrates, and wastewater treatment. Their working principle utilizes gravity to allow solid particles in the slurry to settle naturally in the liquid, thus achieving solid-liquid separation. During this process, the sediment needs to be cleaned promptly and effectively to ensure the continuous and stable operation of the settling tank and its efficient separation effect.

[0003] Existing sedimentation tanks typically only have fixed scrapers at the bottom. These fixed scrapers can only clean a portion of the bottom area of ​​the sedimentation tank, and are ineffective at cleaning sediment near the tank walls and in the corners of the inverted conical bottom surface. Over time, these residual sediments will gradually accumulate, reducing the efficiency of solid-liquid separation. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a settling tank that is easy to clean, which effectively solves the problem that the fixed scraper has a limited settling range and poor cleaning effect.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a settling tank that facilitates sedimentation and cleaning, comprising a settling tank, the bottom of which is an inverted conical structure, a discharge port at the bottom of which is provided, a horizontal support plate fixed at the top of which is fixed, a drive motor installed at the center of which is fixedly connected, a vertical rotating shaft fixedly connected to which is provided, a plurality of stirring rods evenly spaced on the outer surface of which is provided, a stirring frame on which is provided, the bottom of which is a cylindrical structure parallel to the inverted conical surface of which is set, and a plurality of mounting sleeves slidably fitted on which are mounted, a bottom scraper fixedly attached to the bottom surface of which is set on which is mounted, and a drive assembly fixedly connected to which is mounted.

[0006] Preferably, the drive assembly includes an external rod fixed to the outer surface of the mounting sleeve. One end of the external rod is fixedly connected to a bottom plate parallel to the mounting sleeve. A support rod is fixed to the bottom plate, and a top plate parallel to the bottom plate is fixed to the top of the support rod. An external plate is fixed to the outer surface of the top of the rotating shaft, and a cylinder connected to the top plate is fixed to the external plate. The cylinder is located on the extension line of the top plate.

[0007] Preferably, one end of the stirring rod is fixed with a side scraper that is in close contact with the inner wall of the sedimentation tank.

[0008] Preferably, both sides of the side scraper and the bottom scraper are concave surfaces.

[0009] Preferably, an inclined reinforcing rod one is fixed between the rotating shaft and the stirring rod, and an inclined reinforcing rod two is fixed between the side scraper and the stirring reinforcing rod one.

[0010] Preferably, the discharge port is equipped with an automatic discharge valve.

[0011] The beneficial effects of the above-mentioned structure of this utility model are as follows: by setting a movable bottom scraper on the inverted conical bottom surface of the sedimentation tank, and with the help of a cylinder, the entire inverted conical bottom surface can be covered, and the sediment in the corners and edges can also be thoroughly cleaned, which greatly improves the comprehensiveness of cleaning; by setting a side scraper on the inner side wall of the sedimentation tank, the sediment attached to the tank wall can be effectively removed, avoiding the sediment from accumulating and hardening on the tank wall, and improving the separation effect of mineral processing.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, the present invention proposes a sedimentation tank for easy sedimentation and cleaning, comprising a sedimentation tank 1, the bottom of which is an inverted conical structure, and a discharge port 2 at the bottom of the sedimentation tank 1. An automatic discharge valve 18 is provided inside the discharge port 2. When the discharge port 2 is opened, the sediment is discharged. A horizontal support plate 3 is fixed at the top of the sedimentation tank 1. A drive motor 4 is installed at the center of the support plate 3. A vertical rotating shaft 5 is fixedly connected to the drive motor 4. Multiple stirring rods 6 are evenly spaced on the outer surface of the rotating shaft 5. A stirring frame 7 is provided on the stirring rod 6. The bottom of the stirring frame 7 is a cylindrical structure parallel to the inverted conical surface of the sedimentation tank 1, and several mounting sleeves 8 are slidably sleeved on it. A bottom scraper 9 that is close to the bottom surface of the sedimentation tank 1 is fixed on the mounting sleeve 8. A drive assembly 10 is fixedly connected to the mounting sleeve 8.

[0020] like Figure 3 As shown, the drive assembly 10 includes an external rod 11, which is fixed to the outer side of the mounting sleeve 8. One end of the external rod 11 is fixedly connected to a bottom plate 12 parallel to the mounting sleeve 8. A support rod 13 is fixed on the bottom plate 12, and a top plate 14 parallel to the bottom plate 12 is fixed to the top of the support rod 13. An external plate 20 is fixed to the outer side of the top of the rotating shaft 5, and a cylinder 19 connected to the top plate 14 is fixed on the external plate 20. The cylinder 19 is located on the extension line of the top plate 14. The cylinder 19 drives the top plate 14, the support rod 13, the bottom plate 12 and the external rod 11 to move, thereby driving the mounting sleeve 8 and the bottom scraper 9 to reciprocate and clean the sediment at the bottom of the sedimentation tank 1.

[0021] like Figure 1 , 3 As shown, one end of the stirring rod 6 is fixed with a side scraper 15 that is close to the inner wall of the sedimentation tank 1 to remove the sediment attached to the tank wall. The length of the side scraper 15 should be designed according to the height of the sedimentation tank 1 and the actual sediment attachment situation to ensure that it can cover most of the easily sedimented areas. An inclined reinforcing rod 16 is fixed between the rotating shaft 5 and the stirring rod 6, and an inclined reinforcing rod 2 17 is fixed between the side scraper 15 and the reinforcing rod 16 to increase stability.

[0022] like Figure 1-3 As shown, both sides of the side scraper 15 and the bottom scraper 9 are concave, which can better fit the inner wall and bottom of the sedimentation tank 1. When scraping the sediment, the concave surface has a larger contact area with the tank wall and bottom. Compared with the flat scraper, it can more effectively gather and collect the sediment, prevent the sediment from being missed or scattered during the scraping process, and further improve the cleaning efficiency.

[0023] In practical use, after the sedimentation tank 1 has been running for a period of time, the cylinder 19 starts to work. The cylinder 19 drives the top plate 14, support rod 13, bottom plate 12 and external rod 11 to move, which in turn drives the mounting sleeve 8 and bottom scraper 9 to reciprocate, cleaning the sediment at the bottom of the sedimentation tank 1 and scraping up the material settled at the bottom. At the same time, the drive motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring rod 6 and stirring frame 7 to rotate. At the same time, the bottom scraper 9 and side scraper 15 rotate. The side scraper 15 rotates along the inner wall of the sedimentation tank 1, scraping off the sediment attached to the tank wall. The scraped-off and scraped-up sediment is discharged from the discharge port 2 along the inclined surface of the bottom of the sedimentation tank 1, completing the cleaning.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
