[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the prior art in this embodiment has the following problems: The inventors have found that the prior art has the following defects: First, the blade inclination angle cannot be adjusted according to different operating conditions; Second, the mixing efficiency of the molten liquid and the heating efficiency of the device have a large room for improvement; Third, the molten liquid is easily splashed onto the top cover when stirred vigorously, resulting in waste of raw materials;

[0022] Therefore, the inventor provides a stirring mechanism for crystalline silicon solid waste smelting, including a smelting furnace body, a stirring mechanism, and a controller 1. The stirring mechanism is arranged above the smelting furnace body, and the controller 1 is arranged on the left side of the front end of the stirring mechanism. The controller 1 is connected to the smelting furnace body and the stirring mechanism by telecommunication. The stirring mechanism also includes a control mechanism a and a control mechanism b. The control mechanism b for controlling the inclination angle of the blade 16 is arranged on the right side of the control mechanism a for controlling the overall rotation of the stirring mechanism. The control mechanism b also includes a support b11, a drive motor b12, a transmission shaft 13, a bevel gear a14, and a bevel gear. b15, blades 16, rotating bearing b17, support b11 is set at the upper end of gear b8, drive motor b12 is set on the support b11, the upper end of the transmission shaft 13 is connected to the output end of the drive motor b12, the bevel gear a14 is set in the middle of the transmission shaft 13, the bevel gears b15 are respectively arranged on both sides of the bevel gear a14 and mesh with the bevel gear a14, the blades 16 are respectively arranged on the left and right sides of the bevel gears b15 on both sides, and the blades 16 and the bevel gears b15 are connected by a shaft, and the rotating bearing b17 is set at the end of the transmission shaft 13 and is rotatably connected to the transmission shaft 13.

[0023] By adopting the above scheme, after the solid waste material is put into the smelting furnace for smelting, the operator controls the control mechanism a through the controller 1 to start stirring the molten liquid. During the process, the inclination angle of the blade 16 is controlled by the control mechanism b, and the support b11 rotates with the gear b8. The drive motor b12 drives the bevel gear a14 to rotate through the transmission shaft 13, and the bevel gear a14 drives the bevel gear b15 to rotate, thereby changing the inclination angle of the blades 16 on both sides, thereby achieving the purpose of adjusting the inclination angle of the blade 16 to cope with different smelting conditions. According to the state of the material under different working conditions, the mixing and lifting effect of the material is controlled. At the same time, during the stirring process of the molten liquid, the structure on the inner wall of the smelting furnace enhances the mixing efficiency of the molten liquid when it is stirred, and continues to heat it, thereby improving the heating and smelting efficiency. After sufficient smelting, the kinetic energy generated by the boiling turbulence in the upper layer of the molten liquid will be offset by the flow stabilizer 4 set in the upper layer inside the smelting furnace to prevent splashing.

[0024] Furthermore, the inner wall of the smelting furnace body is provided with a flow-disturbing protrusion 2 to enhance the disturbance of the molten liquid during stirring and improve the mixing effect;

[0025] The spoiler protrusions 2 are arranged on the inner wall of the smelting furnace. When the device stirs the molten liquid, the spoiler protrusions 2 can improve the mixing effect of the materials.

[0026] Furthermore, the interior of the spoiler protrusion 2 is connected to the heating component 3, which increases the contact area between the heating component 3 and the melt and improves the heating effect;

[0027] The interior of the spoiler protrusion 2 is connected to the heating component 3, which not only improves the material mixing effect by contacting with the molten liquid, but also increases the contact area with the material, thereby improving the heating effect.

[0028] Furthermore, a flow stabilizing plate 4 with holes is provided on the upper part of the inner wall of the smelting furnace body to reduce the turbulent flow effect of the upper molten liquid and prevent the molten liquid from splashing;

[0029] The flow stabilizing plate 4 can absorb the kinetic energy generated when the upper molten liquid boils, thereby preventing the upper liquid level from splashing due to boiling and causing waste of raw materials.

[0030] Furthermore, the control mechanism a also includes a support a5, a drive motor a6, a gear a7, a gear b8, a sleeve 9, and a rotating bearing a10. The drive motor is disposed on the support a5, and the output end of the drive motor is connected to the gear a7. The gear a7 is disposed on the left side of the gear b8 and meshes with the gear b8. The lower end of the gear b8 is connected to the upper end of the sleeve 9. The sleeve 9 extends into the smelting furnace body and the lower end is rotatably connected to the rotating bearing a10.

[0031] The driving motor a6 drives the gear a7 to rotate, the gear a7 drives the gear b8 to rotate, and the gear b8 drives the sleeve 9 to rotate on the rotating bearing a10, thereby rotating the stirring mechanism to realize the stirring function.

[0032] In summary, the device includes a smelting furnace body, a stirring mechanism, and a controller 1. The stirring device can automatically adjust the inclination angle of the stirring blade 16 to cope with different working conditions; a structure is provided inside the smelting furnace body to prevent the molten liquid from splashing to prevent the waste of raw materials; a spoiler protrusion 2 is provided on the inner wall of the smelting furnace body, which has the function of spoiling and heating, further improving the mixing efficiency and heating efficiency of the device.

[0033] The working principle of the present invention is as follows: the operator puts the solid waste material into the smelting furnace, and after smelting and heating, the stirring mechanism is started through the controller 1. The driving motor a6 in the control mechanism a drives the gear a7 to rotate, and the gear a7 drives the gear b8 to rotate, so that the sleeve 9 on the gear b8 rotates on the rotating bearing to realize the stirring function of the stirring mechanism. At the same time, the gear b8 drives the driving motor b12 set on the support b11 above the gear b8 to rotate. The driving motor b12 is controlled by the controller 1 to drive the bevel gear a14 on the transmission shaft 13 to rotate, and the bevel gear a14 drives the bevel gears b15 on both sides to rotate. The rotation directions of the bevel gears b15 on both sides are opposite, so that the blades 16 on both sides rotate in opposite directions. In this way, the blades 16 stir the molten liquid so that the molten liquid can be continuously stirred. Stirring and mixing upwards, and adjusting the inclination angle of the blade 16 according to the different working conditions in the smelting furnace; while the stirring mechanism is stirring, the molten liquid is continuously rotating and flipping up and down, and the spoiler protrusions 2 provided on the inner wall of the smelting furnace can enhance the mixing efficiency of the molten liquid, and the part of the spoiler protrusion 2 connected to the heating component 3 can continuously heat the molten liquid, thereby increasing the contact area between the heating component 3 and the molten liquid and improving the heating efficiency; as the molten liquid is fully mixed and heated, the upper layer of the molten liquid will splash under the action of stirring and boiling, and the splashing will stick to the top cover and cause waste of material resources. At this time, the flow stabilizer 4 provided on the upper part of the inner wall of the smelting furnace can offset the kinetic energy generated by stirring and boiling, thereby ensuring the stability of the upper layer of the molten liquid and saving raw material resources; until the smelting is completed and discharged;

[0034] At this point, the working principle of the device has been explained.
