[0002] Bucket elevator mainly consists of bucket, traction belt (or chain, plate chain), driven device, casing, feed port, discharge port, etc. It usually uses a series of buckets evenly fixed on the circular traction chain or belt to continuously lift bulk or crushed materials in the vertical direction or near vertical direction.

[0003] During the use of the existing wear-resistant closed elevator for industrial silicon smelting, silicon powder will accumulate at the bottom of the inner side of the casing. The hopper cannot directly touch the bottom of the inner side of the casing when rolling and digging materials. To prevent unnecessary wear, the casing needs to be manually opened and cleaned regularly, which is very inconvenient. Utility Model Content

[0005] Preferably, the inner side surfaces of the first sealing plate and the second sealing plate are both provided with sealing bosses adapted to the discharge opening.

[0006] Preferably, a roller is fixedly mounted on the bottom of the dust collecting box.

[0007] Preferably, the internal fixing sleeve of the connecting rod is provided with limiting rods symmetrically distributed on the outside of the top end of the hydraulic cylinder.

[0008] Preferably, a magnet is provided inside the dust box. Beneficial effects

[0009] 1. The wear-resistant closed elevator for industrial silicon smelting can drive the first sealing plate and the second sealing plate to rotate around the axial direction of the first fixed rod and the second fixed rod respectively through the drive of the hydraulic cylinder, and at the same time open the discharge port at the bottom of the casing. At this time, the silicon powder remaining at the bottom of the inner side of the casing can fall to the inside of the dust box under the action of its own gravity for collection. At this time, the dust box can be pulled out from the inner side of the bottom shell, and the silicon powder collected inside the dust box can be cleaned. This structure can automatically realize regular cleaning of the casing, which is very convenient to use.

[0010] 2. The wear-resistant closed elevator for industrial silicon smelting can reduce the gap between the hopper and the first and second sealing plates by arranging sealing bosses that are compatible with the discharge port on the inner side surfaces of the first and second sealing plates, so that silicon powder can be transported by flipping the hopper. It is not easy for it to accumulate at the bottom of the inner side of the casing, and the residual amount of silicon powder can be reduced by regularly cleaning the casing, thereby reducing the wear on the hopper.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0019] See also Figure 1-4 A wear-resistant closed elevator for industrial silicon smelting includes a casing 1 and a bottom casing 2 arranged on the outside of the bottom of the casing 1, a feed port 3 arranged at the bottom of one side of the casing 1, a discharge port 4 arranged at the top of the other side of the casing 1, a driving wheel 5 and a driven wheel 6 rotatably connected to the inside of the casing 1, a chain plate 7 sleeved on the outside of the driving wheel 5 and the driven wheel 6, and a hopper 8 fixedly mounted on the outside of the chain plate 7. A discharge port located on the inside of the bottom casing 2 is opened at the bottom of the casing 1, and a transparent observation window is provided on the side of the casing 1. The inside of the bottom casing 2 is movably sleeved with a first fixing rod 9 and a second fixing rod 10. The outsides of the first fixing rod 9 and the second fixing rod 10 are respectively fixedly sleeved with a first sealing plate 11 and a second sealing plate 12 located on the outside of the bottom of the casing 1. The bottom casing 2 A support 13 is provided on both sides of the housing 1, and the interior of the support 13 is rotatably connected to the hydraulic cylinder 15 through a fixing pin 14. The outer sides of both ends of the first fixing rod 9 extending out of the outside of the bottom shell 2 are fixedly sleeved with a fixing plate 16, and the interior of the fixing plate 16 is fixedly sleeved with a connecting rod 17 movably sleeved on the top of the hydraulic cylinder 15. The drive of the hydraulic cylinder 15 can drive the first sealing plate 11 and the second sealing plate 12 to rotate around the axial direction of the first fixing rod 9 and the second fixing rod 10 respectively, while opening the discharge port at the bottom of the casing 1. A dust box 18 is placed on the inside of the bottom shell 2 below the casing 1. The dust box 18 allows the first sealing plate 11 and the second sealing plate 12 to be opened to collect silicon powder falling from the bottom inner side of the casing 1.

[0020] Among them, the inner sides of the first sealing plate 11 and the second sealing plate 12 are both provided with a sealing boss 19 adapted to the discharge port. The sealing boss 19 can reduce the distance between the first sealing plate 11 and the second sealing plate 12 and the hopper 8, so that the silicon powder is not easy to gather at the bottom of the inner side of the casing 1 during the flipping movement of the hopper 8, and after the first sealing plate 11 and the second sealing plate 12 are closed, the discharge port can be blocked and sealed by the sealing boss 19 to prevent the silicon powder from leaking during the transportation of the silicon powder by the elevator.

[0021] Among them, a roller 20 is fixedly installed at the bottom of the dust box 18. The roller 20 can support the dust box 18 and facilitate the manual pulling of the dust box 18 from the inner side of the bottom shell 2 to clean the silicon powder collected inside the dust box 18.

[0022] Among them, the internal fixed sleeve of the connecting rod 17 is equipped with a limiting rod 21 symmetrically distributed on the outside of the top end of the hydraulic cylinder 15. The limiting rod 21 can limit the piston rod inside the hydraulic cylinder 15, so that the piston rod of the hydraulic cylinder 15 will not move along the axial direction of the connecting rod 17 during the driving process, thereby preventing the piston rod from bending when subjected to external force, and when the hydraulic cylinder 15 is driven, both ends of the first fixed rod 9 can apply driving force, thereby ensuring that the first sealing plate 11 and the second sealing plate 12 can stably close the discharge port.

[0023] The dust box 18 is provided with a magnet 22 inside, which can magnetically attract the bottom shell 2 and magnetically fix the dust box 18, preventing the dust box 18 from detaching from the inside of the bottom shell 2. The dust box 18 can be manually pulled to overcome the magnetic attraction and move the dust box 18, so as to facilitate the disassembly and assembly of the dust box 18.

[0024] When cleaning the silicon powder at the bottom inner side of the casing 1, the hydraulic cylinder 15 is started, and the first sealing plate 11 and the second sealing plate 12 are driven by the hydraulic cylinder 15 to rotate around the axial direction of the first fixing rod 9 and the second fixing rod 10 respectively, while the discharge port at the bottom of the casing 1 is opened. At this time, the silicon powder at the bottom inner side of the casing 1 falls to the inner side of the dust collecting box 18 under the action of its own gravity for collection. The hydraulic cylinder 15 is started to move in the opposite direction, and the first sealing plate 11 and the second sealing plate 12 are driven by the hydraulic cylinder 15 to move in the opposite direction around the axial direction of the first fixing rod 9 and the second fixing rod 10 while closing the discharge port, thereby completing the cleaning of the silicon powder inside the casing 1;

[0025] The silicon powder collected inside the dust box 18 is observed through the transparent observation window on the side of the casing 1. When a large amount of silicon powder is collected, the dust box 18 is manually pulled out from the inner side of the bottom shell 2, and the silicon powder collected inside the dust box 18 is cleaned.
