[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a feeding device for inorganic silicon production, including a support frame 1, the bottom of the support frame 1 is evenly installed with moving wheels, which is convenient for moving the entire device. The top of the support frame 1 is fixedly installed with a main body 2, which is hollow inside and has a cylindrical structure, and the main body 2 is arranged horizontally. The top of the main body 2 is installed with a feed pipe 4 communicating with its inside, and the bottom of the main body 2 is installed with a discharge pipe 5 communicating with its inside. The discharge pipe 5 is located on the right side of the bottom of the main body 2, and a valve is installed on the discharge pipe 5 to control the outflow of raw materials.

[0019] A rotating shaft 13 is horizontally rotatably installed inside the main body 2, and both ends of the rotating shaft 13 are rotatably installed in cooperation with the center positions on the left and right sides inside the main body 2. A motor 3 is fixedly installed on the left side of the main body 2, and the output shaft of the motor 3 passes through the main body 2 and is fixedly connected to the rotating shaft 13 coaxially. Circular plates 7 and fixing plates 15 are respectively fixedly installed at both ends of the rotating shaft 13, a lead screw 8 is rotatably installed between the circular plate 7 and the fixing plate 15, and one end of the lead screw 8 passes through the circular plate 7 to the left and is fixedly sleeved with a gear 14. A ring gear 6 is fixedly arranged on the left side inside the main body 2, the ring gear 6 is rotatably installed in cooperation with the circular plate 7, and the ring gear 6 is meshed with the gear 14.

[0020] A push plate 9 is threadedly connected to a lead screw 8, and the push plate 9 is slidably fitted and installed with a rotating shaft 13. A stirring cylinder 10 is rotatably installed on one side of the push plate 9. The stirring cylinder 10 is slidably sleeved on the lead screw 8, and the lead screw 8 and the stirring cylinder 10 do not rotate relative to each other. A plurality of stirring blades 11 are fixedly installed on the outer periphery of the stirring cylinder 10, and the plurality of stirring blades 11 are arranged in an array. A guiding groove is formed in the outer periphery of the lead screw 8 along its length direction, and a guiding block is fixedly installed inside the stirring cylinder 10. The guiding block is slidably installed in the guiding groove. This prevents the stirring cylinder 10 from rotating relative to the lead screw 8.

[0021] A pushing ring is fixedly installed on the push plate 9. The pushing ring is in contact with the inner wall of the main body 2. The side of the pushing ring away from the discharge pipe 5 is a slope, which facilitates the raw materials in the main body 2 to pass through the pushing ring.

[0022] The thread on the outer periphery of the lead screw 8 is a reciprocating thread. The push plate 9 is connected to the lead screw 8 through a nut. The nut and the lead screw use steel balls as rolling elements, so that the lead screw, the nut and the steel balls form a ball screw pair. It is not necessary for the motor 3 to rotate forward and backward to realize the reciprocating movement of the push plate 9.

[0023] A heating plate 12 is fixedly installed between the circular plate 7 and the fixing plate 15. The heating plate 12 is parallel to the rotating shaft 13 and the lead screw 8 respectively. The heating plate 12 heats the raw materials.

[0024] The working principle of a feeding device for inorganic silicon production provided by the present utility model is as follows:

[0025] During feeding, the raw materials are added into the main body 2 through the feeding pipe 4. The heating plate 12 and the motor 3 are started. The output shaft of the motor 3 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the circular plate 7 and the fixing plate 15 to rotate synchronously. The circular plate 7 drives the lead screw 8 and the heating plate 12 to rotate around the rotating shaft 13 respectively. At the same time, the lead screw 8 drives the gear 14 to rotate around the rotating shaft 13. Since the gear 14 meshes with the ring gear 6, the gear 14 drives the lead screw 8 to rotate. The rotation of the lead screw 8 drives the stirring cylinder 10 to rotate, and the rotation of the stirring blades 11 facilitates the dispersion of the coagulated raw materials.

[0026] The rotation of the lead screw 8 also drives the push plate 9 to reciprocate along the lead screw 8. The push plate 9 drives the pushing ring to reciprocate along the inner wall of the main body 2. During the reciprocating movement of the pushing ring, since the side of the pushing ring away from the discharge pipe 5 is a slope, when the pushing ring moves to the left, it is convenient for the raw materials in the main body 2 to pass through the pushing ring. Therefore, when the pushing ring reciprocates, the raw materials can be continuously pushed into the discharge pipe 5, which is convenient for discharging from the discharge pipe 5. At the same time, the pushing ring can scrape off the raw materials adhered to the inner wall of the main body 2, avoiding waste of raw materials.

[0027] While the mixing drum 10 rotates around the rotating shaft 13, and the pushing plate 9 drives the mixing drum 10 to reciprocate, the mixing drum 10 mixes the raw materials more evenly through the mixing blades 11. The heating plate 12 rotates around the rotating shaft 13 to uniformly heat the raw materials, increasing the heating efficiency of the raw materials.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
