Description

Technical Field

[0001] This utility model relates to the field of silicon carbide technology, and more specifically, to a silicon carbide grinding device. Background Technology

[0002] Silicon carbide is widely used in the manufacture of wear-resistant materials, refractory materials, and metallurgical raw materials due to its stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and good wear resistance. During the manufacturing and processing of silicon carbide, grinding is required.

[0003] A search revealed that utility model patent CN213102348U discloses a silicon carbide grinding device, including a fixed cylinder with an open top. A cover plate is detachably connected to the top of the fixed cylinder, and a feeding pipe is fixed to one side of the top of the cover plate. A discharge pipe is provided at the bottom of the fixed cylinder. A vertically placed rotating rod is rotatably connected to the middle of the cover plate via a bearing, and a grinding element is fixed to the bottom of the rotating rod. A drive motor is connected to the top of the rotating rod. A filter plate is fixed to the inner wall of the fixed cylinder at the bottom of the grinding element, and a gap is provided between the top of the filter plate and the bottom of the grinding element. The grinding cylinder is fixed to the top of the filter plate. This patent uses an arc angle where the bottom end of the guide plate at the top of the grinding element extends beyond the outer wall of the grinding element. This allows the guide plate to scrape away stuck particles during the rotation of the grinding element and facilitates the material to slide evenly into the grinding chamber between the two streamlined guide plates, ensuring continuous and normal grinding operations and preventing wear on the grinding element.

[0004] However, the aforementioned patents still have the following shortcomings: although the combination of the grinding elements and the grinding cylinder can grind silicon carbide, the fixed filter plate is not convenient for screening materials, and materials that do not meet the grinding requirements are not convenient to be re-ground by the grinding elements and the grinding cylinder. To address this, we propose a silicon carbide grinding device. Utility Model Content

[0027] For details, please refer to Figures 1 to 4 The return material mechanism 2 includes a return material square tube 12 fixedly sleeved on the side of the grinding box 1. A lifting cylinder 13 is fixedly connected to the end of the return material square tube 12. A feeding square tube 14 is fixedly connected to the side of the top of the lifting cylinder 13. The end of the feeding square tube 14 is fixedly sleeved into the inner cavity of the grinding box 1. A spiral conveying rod 15 is rotatably connected to the inner cavity of the lifting cylinder 13. A second motor 16 is fixedly installed on the top surface of the lifting cylinder 13. The output shaft of the second motor 16 is connected to the top of the rotating shaft of the spiral conveying rod 15. A sliding plate 19 is fixedly connected to the side of the bottom end of the filter screen plate 9. The end of the sliding plate 19 is movably sleeved into the inner cavity of the return material square tube 12. The side of the sliding plate 19 is in contact with the inner wall of the return material square tube 12. A rubber elastic cloth 20 is fixedly connected to the bottom of the sliding plate 19. The bottom of the rubber elastic cloth 20 is connected to the bottom of the inner cavity of the return material square tube 12.

[0028] In this embodiment, the rubber elastic cloth 20 is used to prevent the material entering the return square tube 12 from moving back to the inner cavity of the grinding box 1 from below the inner cavity of the return square tube 12.

[0029] For details, please refer to Figure 3 The top surface of the grinding box 1 is fixedly fitted with a feed inlet 11, and the bottom of the grinding box 1 is provided with a discharge outlet 10.

[0030] In this embodiment, the silicon carbide material to be ground is put into the inner cavity of the grinding chamber 1 through the feed port 11, and the ground material that meets the conditions is discharged through the discharge port 10.

[0031] For details, please refer to Figure 3 The bottom surface of the grinding box 1 is fixedly connected with multiple support legs 17.

[0032] In this embodiment, the grinding box 1 is supported by the support leg 17.

[0033] For details, please refer to Figure 1 , Figure 2 and Figure 4 A control panel 18 is fixedly installed on the front of the grinding box 1. The control panel 18 is electrically connected to the first motor 4, the second motor 16, and the electric push rod 8.

[0034] In this embodiment, the first motor 4, the second motor 16, and the electric push rod 8 are controlled by the control panel 18.

[0037] Working principle: In use, the control panel 18 first controls the start of the first motor 4, the second motor 16, and the electric push rod 8. The first motor 4 drives the grinding seat 5 to rotate, and the second motor 16 drives the screw conveyor 15 to rotate. At the same time, the electric push rod 8 drives the filter plate 9 to move up and down. Then, the silicon carbide to be ground is put into the inner cavity of the grinding chamber 1 through the feed inlet 11. The grinding seat 5 and the grinding cylinder 3 work together to grind the silicon carbide. The ground material falls onto the filter plate 9 and then passes through the filter plate 9. The silicon carbide is moved up and down, causing the silicon carbide particles that meet the requirements to fall to the bottom of the inner cavity of the grinding box 1 and be discharged from the discharge port 10. The silicon carbide that does not meet the requirements enters the inner cavity of the lifting cylinder 13 through the sliding plate 19. Finally, the rotating spiral conveyor rod 15 drives the silicon carbide material in the lifting cylinder 13 to move upward, and causes the silicon carbide that has moved to the upper part of the inner cavity of the lifting cylinder 13 to be discharged back to the upper part of the inner cavity of the grinding box 1 through the feed square tube 14, so that the silicon carbide can be ground again by the grinding seat 5 and the grinding cylinder 3.
