Description

Technical Field

[0001] This utility model relates to the field of polycrystalline silicon production technology, and in particular to a silicon rod loading machine. Background Technology

[0002] Currently, most domestic polycrystalline silicon production processes use the conventional trichlorosilane hydrogen reduction method, also known as the modified Siemens process. The main equipment for producing large-diameter polycrystalline silicon using the modified Siemens process or other similar methods is the polycrystalline silicon reduction furnace. In this furnace, a power source is applied to a slender silicon core, heating it until the surface temperature reaches 1100 degrees Celsius. High-purity trichlorosilane and hydrogen are then introduced, causing a hydrogen reduction reaction at high temperature. This process causes silicon molecules in the trichlorosilane to accumulate on the silicon core, continuously increasing its diameter. Typically, the silicon core diameter is 7-10 mm, and it can be round, square, or other shapes. Ultimately, through the hydrogen reduction reaction, the diameter is continuously increased to 120-200 mm, producing high-purity solar-grade 6N or electronic-grade I1N polycrystalline silicon.

[0003] The existing technology has the following problems:

[0004] When using a silicon rod loading machine, due to the large size of the device, it is not possible to make fine adjustments to its position on one side of the vertical cutting machine, which affects the flexibility of use and makes it inconvenient to load and unload materials quickly. Furthermore, the stability of the silicon rod loading machine during adjustment cannot be guaranteed, which affects the safety of use. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, the silicon rod loading machine includes a movable base 1, a support assembly 2 fixedly connected to the upper surface of the movable base 1, a hydraulic rod 3 rotatably connected to the inner wall of the lower left part of the support assembly 2, a feeding assembly 4 rotatably connected to the output end of the hydraulic rod 3, the outer wall of the lower part of the feeding assembly 4 rotatably connected to the inner wall of the upper right part of the support assembly 2, and a silicon rod clamping frame 5 fixedly connected to the right side of the feeding assembly 4.

[0026] First, under the action of the movable seat 1, the device can move the silicon rod inside the silicon rod holder 5 to one side of the vertical cutting machine. Then, under the action of the hydraulic system, the hydraulic rod 3 can push the feeding component 4 and the silicon rod holder 5 to rotate and move towards the vertical cutting machine. Next, under the action of the feeding component 4 and the support component 2, the position of the silicon rod is adjusted. Finally, the silicon rod is sent into the interior of the vertical cutting machine for processing.

[0027] like Figure 2As shown, the support assembly 2 includes a support frame 21. The inner wall of the lower left part of the support frame 21 is rotatably connected to the outer wall of the lower left part of the hydraulic rod 3. A connecting frame 26 is fixedly connected to the right side of the upper part of the support frame 21. Slide seats 22 are fixedly connected to the left and right parts of the lower surface of the support frame 21. Two auxiliary support wheels 24 are rotatably connected to the inner walls of the two slide seats 22. The lower surfaces of the outer walls of the four auxiliary support wheels 24 overlap with the upper surface of the movable seat 1. A hydraulic rod 25 is fixedly connected to the inner wall of the middle part of the movable seat 1. The output end of the hydraulic rod 25 is fixedly connected to the rear of the lower middle part of the support frame 21.

[0028] The hydraulic rod 25 enables the support frame 21 to move forward under the action of the slide block 22 and the auxiliary support wheel 24, thereby driving the silicon rod inside the silicon rod holder 5 to move forward. This allows for fine-tuning of the silicon rod position according to the position of the vertical cutting machine during feeding, improving the flexibility of use.

[0029] like Figure 3 As shown, guide rails 23 are slidably connected to the outer walls of the left and right sides of the two slide blocks 22, and the lower surfaces of the four guide rails 23 are fixedly connected to the upper surface of the movable seat 1.

[0030] The guide rail 23 enables the two slide blocks 22 to stably drive the support frame 21 to move back and forth on the upper surface of the movable seat 1, thereby ensuring the stability of the movement and also serving as a guide.

[0031] like Figure 4 As shown, a fixed frame 41 is fixedly connected to the upper and lower sides of the limiting groove plate 44. The outer wall of the lower part of the fixed frame 41 is rotatably connected to the inner wall of the connecting frame 26. Two connecting seats 42 are fixedly connected to the front and rear sides of the fixed frame 41. An auxiliary support wheel 43 is fixedly connected to the left side of the fixed frame 41. The inner wall of the auxiliary support wheel 43 is rotatably connected to the outer wall of the output end of the hydraulic rod 3.

[0032] The hydraulic rod 3 enables the fixed frame 41 to rotate under the action of the connecting seat 42 and the connecting frame 26, thereby rotating the silicon rod to one side of the vertical cutting machine for easy loading.

[0033] A hydraulic rod 45 is fixedly connected to the upper surface of the left part of the limiting groove plate 44. A connecting frame 46 is fixedly connected to the output end of the hydraulic rod 45. The inner wall of the connecting frame 46 is fixedly connected to the outer wall of the upper U-shaped connecting seat 47.

[0034] The hydraulic rod 45 enables the connecting frame 46 to push the silicon rod clamping frame 5 up and down under the action of the two U-shaped connecting seats 47, thereby adjusting the height of the silicon rod.

[0035] like Figure 5As shown, the feeding assembly 4 includes two U-shaped connecting seats 47. The upper surfaces of the right portions of the two U-shaped connecting seats 47 are fixedly connected to the lower surfaces of the left portions of the silicon rod clamping frame 5. The inner walls of the two U-shaped connecting seats 47 are slidably connected to a limiting groove plate 44. Limiting grooves are provided on the front and rear sides of the limiting groove plate 44. The inner walls of the front and rear portions of the two U-shaped connecting seats 47 are rotatably connected to two auxiliary support wheels 48. The opposite faces of several auxiliary support wheels 48 overlap with the inner walls of the limiting grooves on the front and rear portions of the limiting groove plate 44.

[0036] The auxiliary support wheel 48 enables the U-shaped connecting seat 47 to move up and down smoothly and steadily on the outer wall of the limiting groove plate 44, thereby further improving the stability of the silicon rod's up and down movement and enhancing safety in use.

[0037] The working principle of this utility model is as follows: First, under the action of the movable seat 1, the device can move the silicon rod inside the silicon rod clamping frame 5 to one side of the vertical cutting machine. Then, under the action of the hydraulic system, the hydraulic rod 3 can push the fixed frame 41 to rotate and move under the action of the connecting frame 26 and the connecting seat 42, thereby rotating the silicon rod to one side of the vertical cutting machine. Next, through the action of the hydraulic rod 3 45, the connecting frame 46 can push the silicon rod clamping frame 5 to move up and down under the action of the two U-shaped connecting seats 47, thereby adjusting the height of the silicon rod. Then, through the action of the hydraulic rod 25, the support frame 21 can move forward under the action of the slide 22 and the auxiliary support wheel 24, thereby driving the silicon rod inside the silicon rod clamping frame 5 to move forward. Thus, during feeding, the position of the silicon rod can be finely adjusted according to the position of the vertical cutting machine. Finally, the silicon rod is sent into the interior of the vertical cutting machine for processing.
