Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A coal slime thickening scraper includes a thickening tank 1, a horizontal plate 2 is bolted to the top of the thickening tank 1, a rotating shaft 3 is rotatably arranged between the bottom of the horizontal plate 2 and the bottom of the inner wall of the thickening tank 1, a motor 4 is bolted to the top of the horizontal plate 2, the output end of the motor 4 extends into the interior of the horizontal plate 2 and is bolted to the rotating shaft 3, an adjustable bottom scraping wall assembly 5 is provided at the bottom of the surface of the rotating shaft 3, and an adjustable side scraping wall assembly 6 is bolted to the top of the adjustable bottom scraping wall assembly 5.

[0028] The adjustable bottom scraper assembly 5 includes a connecting sleeve 51, which is fixedly sleeved on the bottom of the surface of the rotating shaft 3. Several first bottom scrapers 52 are annularly bolted to the surface of the connecting sleeve 51. A first sliding groove 53 is opened inside the first bottom scraper 52. A second bottom scraper 54 is slidably arranged inside the first sliding groove 53. Several first fixing pins 55 are threadedly connected to the top of the first bottom scraper 52. The bottom of the first fixing pins 55 contacts the top of the second bottom scraper 54.

[0029] In this embodiment: When operating the coal slime thickening scraper, first adjust the adjustable bottom scraper assembly 5 according to the diameter of the thickening tank 1, loosen the multiple first fixing pins 55 threaded to the top of the first bottom scraper 52. Since the first bottom scraper 52 has a first sliding groove 53, the second bottom scraper 54 can slide in it. Slide it along the inside and outside of the groove to change the radius of the bottom scraper to match the diameter of the thickening tank 1. After adjustment, tighten the first fixing pins 55 so that the bottom of the scraper is in close contact with the top of the second bottom scraper 54 to complete the fixation. Then start the motor 4 bolted to the top of the horizontal plate 2. Its output end extends into the horizontal plate 2 to drive the rotating shaft 3 to rotate. The connecting sleeve 51 is fixedly sleeved on the bottom of the surface of the rotating shaft 3 and will rotate with the rotating shaft 3, thereby driving the first bottom scraper 52 and the fixed second bottom scraper 54, which are annularly bolted to the surface of the connecting sleeve 51, to rotate around the axis and scrape the coal slime at the bottom of the inner wall of the thickening tank 1. The adjustable side scraper assembly 6 is responsible for scraping the side wall of the thickening tank 1.

[0030] Specifically, such as Figure 4 As shown, the adjustable side scraper assembly 6 includes a plurality of first side scrapers 61, the bottom of which is bolted to the top of a corresponding second bottom scraper 54.

[0031] Specifically, such as Figure 4 As shown, a second sliding groove 62 is provided inside the first side scraper 61, and a second side scraper 63 is slidably disposed inside the second sliding groove 62.

[0032] Specifically, such as Figure 4 As shown, a number of second fixing pins 64 are threadedly connected to the side of the first side scraper 61 away from the thickening tank 1, and one side of the second fixing pins 64 is in contact with the surface of the second side scraper 63.

[0033] In this embodiment: After adjusting the adjustable bottom scraper assembly 5, the adjustable side scraper assembly 6 also needs to be adjusted according to the height of the thickener 1. Several first side scrapers 61 in the adjustable side scraper assembly 6 are bolted to the top of the corresponding second bottom scraper 54 at their bottom and will move together with the adjustable bottom scraper assembly 5. Loosen several second fixing pins 64 threaded on the side of the first side scraper 61 away from the thickener 1. Because the first side scraper 61 has a second sliding groove 62 inside, the second side scraper 63 slides in the second sliding groove 62. Therefore, the second side scraper 63 can be slid up or down along the second sliding groove 62 according to the height of the thickener 1 to change the height of the side scraper. When the appropriate height is adjusted, tighten the second fixing pins 64 so that one side of the second fixing pin 64 is in close contact with the surface of the second side scraper 63, and fix the second side scraper 63 in the current position. During the process of the motor 4 driving the rotating shaft 3 to rotate, the adjustable side scraper assembly 6 will scrape off the coal sludge on the inner wall side of the thickener 1.

[0034] Specifically, such as Figure 3As shown, a sliding sleeve 7 is provided on the surface of the rotating shaft 3, and several telescopic square rods 8 are bolted to the surface of the rotating shaft 3 in an annular shape.

[0035] Specifically, such as Figure 4 , Figure 3 As shown, the other end of several telescopic square rods 8 is rotatably bolted to the side of the corresponding second side scraper 63 near the second side scraper 63, and the top of the telescopic square rods 8 is threaded with a third fixing pin 9.

[0036] In this embodiment: To further assist in the height adjustment of the adjustable side scraper assembly 6 and ensure its stability, it is necessary to operate the sliding sleeve 7 and the telescopic square rod 8. The sliding sleeve 7 is slid along the surface of the rotating shaft 3. The change in the position of the sliding sleeve 7 on the rotating shaft 3 can drive the telescopic square rod 8 connected to it to adjust its position. The other end of the telescopic square rod 8 is close to the side of the corresponding second side scraper 63 and is rotatably bolted to the second side scraper 63. The third fixing pin 9 threaded on the top of the telescopic square rod 8 is loosened. According to the height adjustment of the second side scraper 63, the telescopic length of the telescopic square rod 8 is adjusted. When the telescopic square rod 8 is adjusted to a suitable length, the third fixing pin 9 is tightened to fix the telescopic square rod 8. In this way, during the operation of the sludge scraper, the telescopic square rod 8 can assist the adjustable side scraper assembly 6 in stably scraping the inner wall side of the thickener 1.

[0037] Specifically, such as Figure 6 As shown, a groove 10 is provided at the bottom of the inner wall of the thickening tank 1. Several stirring rods 11 are bolted to the surface of the rotating shaft 3 located inside the groove 10. Threaded blades 12 are sleeved on the surface of the rotating shaft 3 located inside the groove 10. The side of the threaded blades 12 close to the stirring rods 11 is bolted to the stirring rods 11.

[0038] Specifically, such as Figure 5 , Figure 1 As shown, the inner side wall of the thickening tank 1 is provided with several water filter tanks 13, and the water filter tank 13 is provided with a water filter plate 14. The bottom of the front side of the thickening tank 1 is fixedly connected to the discharge pipe 15, which is connected to the groove 10.

[0039] In this embodiment: During the rotation of the shaft 3 driven by the motor 4, several stirring rods 11 bolted to the surface of the shaft 3 located inside the groove 10 at the bottom of the inner wall of the thickener 1 will rotate together with the shaft 3 to stir the coal slurry in the groove 10 and prevent the coal slurry from settling and clumping. At the same time, the threaded blades 12 sleeved on the inner surface of the shaft 3 located inside the groove 10 will also rotate, and the side of the threaded blades 12 close to the stirring rods 11 will be bolted to the stirring rods 11 to further enhance the stirring and conveying effect on the coal slurry. Several water filter tanks 13 are opened on the side wall inside the thickener 1. Water filter plates 14 are installed inside the water filter tanks 13. During the slurry scraping process, the water in the coal slurry can enter the water filter tanks 13 through the water filter plates 14 to achieve the initial separation of coal slurry and water. After stirring and initial separation, the coal slurry is discharged from the thickener 1 through the discharge pipe 15 connected to the groove 10, completing the coal slurry scraping and discharge process.

[0040] Working principle: First, adjust the adjustable bottom scraper assembly 5 according to the diameter of the thickener 1. Loosen the multiple first fixing pins 55 on the top of the first bottom scraper 52. Using the first sliding groove 53 inside the first bottom scraper 52, slide the second bottom scraper 54 along the groove to change the bottom scraper radius. After adapting to the diameter of the thickener 1, tighten the first fixing pins 55 to complete the fixation. Then, start the motor 4 on the top of the horizontal plate 2. Its output end drives the rotating shaft 3 to rotate. The connecting sleeve 51 rotates with the rotating shaft 3, thereby driving the annular bolt on the surface of the connecting sleeve 51. The first bottom scraper 52 and the fixed second bottom scraper 54 rotate around an axis to scrape off the coal sludge at the bottom of the inner wall of the thickener 1. At the same time, the adjustable side scraper assembly 6 is adjusted. Since the bottom of several first side scrapers 61 are bolted to the top of the corresponding second bottom scrapers 54, they will move with the adjustable side scraper assembly 5. The second fixing pin 64 on the first side scraper 61 is loosened, and the second side scraper 63 is slid up and down along the groove 62 in the first side scraper 61 to change the height of the side scraper. After the adjustment is appropriate, the second fixing pin is tightened. 64 is fixed. To further assist in adjustment and ensure stability, the sliding sleeve 7 slides along the rotating shaft 3, driving the connected telescopic square rod 8 to adjust its position. The other end of the telescopic square rod 8 is rotatably bolted to the second side scraper 63. Loosen the third fixing pin 9 at the top of the telescopic square rod 8, and adjust the telescopic length according to the height of the second side scraper 63. After it is appropriate, tighten it to fix it. During the rotation of the rotating shaft 3 driven by the motor 4, the adjustable side scraper assembly 6 scrapes the coal sludge on the inner wall of the thickener 1. The rotating shaft 3 is located in the groove 10 at the bottom of the inner wall of the thickener 1. The surface-mounted stirring rod 11 rotates with the rotating shaft 3 to stir the coal slurry and prevent sedimentation and agglomeration. The threaded blades 12, which are sleeved on the inner surface of the groove 10 of the rotating shaft 3, also rotate and are bolted to the stirring rod 11 to enhance the stirring and conveying effect. In addition, there is a filter plate 14 in the water filter trough 13 on the side wall of the thickener 1. When scraping the slurry, the water in the coal slurry enters the water filter trough 13 through the water filter plate 14 to achieve preliminary separation. After stirring and separation, the coal slurry is discharged from the thickener 1 through the discharge pipe 15 connected to the groove 10, completing the scraping and discharge process.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
