Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon production, in particular to a conveying device for industrial silicon production. Background Art

[0002] Crystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into grains with different crystal plane orientations, these grains will combine to form polycrystalline silicon.

The utility model drives the rotating shaft and the conveying blade to rotate through the second motor, and the silicon raw material in the feed hopper is lifted through the feed pipe through the conveying blade, so that the silicon raw material falls into the feed pipe, and the turntable and the partition frame are driven to rotate by the first motor. When the feed hole and the feed pipe correspond, the silicon raw material falls into the material cavity, and the silicon raw material rotates in the material cavity, so that the silicon raw material falls evenly into the interior of the industrial silicon furnace through the discharge trough, and then the silicon raw material is evenly added to the industrial silicon furnace, so that the feeding of the industrial silicon furnace is relatively uniform.

[0004] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: the above-mentioned feeding device transports materials through a conveying blade. Due to the limited space in the transportation pipeline, when the silicon raw material is large in volume, it is easy to get stuck in the feeding pipe. Utility Model Content

[0021] The embodiment of the present application effectively solves the above-mentioned feeding device by providing a conveying device for industrial silicon production. The material is transported by a conveying blade. Due to the limited space in the transportation pipeline, when the silicon raw material is large in volume, it is easy to get stuck in the feed pipe. The material is poured into the upper hopper, and the first power box at the side end is started. The reduction gear set inside the first power box will increase the torque of the motor, driving the two crushing barrels to rotate inward, so that the material falls into the conveying pipe. In this process, the two inwardly rotating crushing barrels will crush the large pieces of raw material in the upper hopper into small pieces. After the small pieces of raw material enter the conveying pipe, the second power box drives the feeding rod to rotate, and the rotating feeding rod will convey the raw material to the conveying pipe. At the opening at the other end, the raw materials that are crushed into small pieces are easier to be refined after entering the smelting furnace. The large pieces of raw materials are crushed by two crushing barrels, which achieves the effect of avoiding material jamming and improving smelting efficiency. When the feeding height needs to be adjusted, the hydraulic cylinder starts to push the fixed ring upward, and the fixed ring drives the conveying pipe to rotate to increase the height of the end of the conveying pipe. During this process, the angle between the conveying pipe and the connecting plate rotates, and the connecting plate will pull the sliding plate to slide downward, so that the connection between the upper hopper and the conveying pipe remains in a closed state to avoid leakage of raw materials. The connection between the upper hopper and the conveying pipe is closed by the connecting plate and the sliding plate, so that no leakage occurs when the conveying pipe rotates to raise the discharge port.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the silicon raw material is easily stuck in the feed pipe when the volume is large due to the limited space of the transport pipeline. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a conveying device for industrial silicon production, including an upper hopper 1, a conveying pipe 2 is rotatably installed at the bottom end of the upper hopper 1, a connecting plate 3 is rotatably installed at the top end of the conveying pipe 2, and a sliding plate 4 is rotatably installed at the top end of the connecting plate 3; the sliding plate 4 slides inside the upper hopper 1, and two crushing barrels 6 are rotatably installed inside the upper hopper 1.

[0025] A first power box 7 is fixedly installed on the side end of the upper hopper 1; a motor and a reduction gear set are installed inside the first power box 7 to drive the crushing barrel 6 to rotate, and a feeding rod 5 is installed inside the conveying pipe 2, and a second power box 8 is fixedly installed on the side end of the conveying pipe 2.

[0026] A motor and a reduction gear set are installed inside the second power box 8, which are used to drive the feeding rod 5 to rotate. A base 9 is fixedly installed at the bottom end of the upper hopper 1, a hydraulic cylinder 11 is fixedly installed at the top of the base 9, and a fixing ring 12 is fixedly installed on the outer wall of the conveying pipe 2; the bottom end of the fixing ring 12 is rotatably connected to the hydraulic cylinder 11.

[0027] Working principle:

[0028] In the first step, the material is poured into the upper hopper 1, and the first power box 7 at the side end is started. The reduction gear set inside the first power box 7 will increase the torque of the motor, driving the two crushing barrels 6 to rotate inward, so that the material falls into the conveying pipe 2. In this process, the two inward rotating crushing barrels 6 will crush the large pieces of raw materials in the upper hopper 1 into small pieces. After the small pieces of raw materials enter the conveying pipe 2, the second power box 8 drives the feeding rod 5 to rotate, and the rotating feeding rod 5 will convey the raw materials to the opening at the other end of the conveying pipe 2. The raw materials crushed into small pieces are easier to be refined after entering the smelting furnace. The large pieces of raw materials are crushed by the two crushing barrels 6, which achieves the effect of avoiding material jamming and improving smelting efficiency.

[0029] In the second step, when it is necessary to adjust the feeding height, the hydraulic cylinder 11 starts to push the fixed ring 12 upward, and the fixed ring 12 drives the conveying pipe 2 to rotate so that the height of the end of the conveying pipe 2 rises. In this process, the angle between the conveying pipe 2 and the connecting plate 3 rotates, and the connecting plate 3 will pull the sliding plate 4 to slide downward, so that the connection between the upper hopper 1 and the conveying pipe 2 remains in a closed state to avoid leakage of raw materials. The connection between the upper hopper 1 and the conveying pipe 2 is closed by the connecting plate 3 and the sliding plate 4, so that the material will not leak when the conveying pipe 2 rotates to raise the discharge port.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
