Description
Technical Field

[0002] In the process of smelting silicon metal, the feeding stage is a key step to ensure smelting efficiency and product quality.
[0003] Traditionally, silicon metal smelting furnaces are fed by directly conveying the silicon raw material into the furnace via an auger. However, during mining, transportation, and storage, silicon raw materials often form large lumps. If these lumps enter the auger directly, they can easily cause blockages, reducing feeding efficiency, potentially damaging the conveying equipment, and increasing maintenance costs and downtime.
[0004] Furthermore, large, uncrushed pieces of metallic silicon raw material cannot fully contact the high-temperature environment and other reactants within the smelting furnace, leading to incomplete smelting reactions, prolonged smelting time, increased energy consumption, and negatively impacting the purity and quality of the metallic silicon. Therefore, inventing a feeding structure for a metallic silicon smelting furnace to address these issues has become a pressing problem for those skilled in the art. Utility Model Content

A fixing plate 218 is fixedly installed on the outer side of the pressing plate 215. The pressing plate 215 and the fixing plate 218 are connected in a transmission and pressing manner.
[0030] Please see Figure 3 The support frame 110 includes a base plate 111. Four casters 112 are fixedly connected to the bottom corners of the base plate 111. Support columns 113 are fixedly installed on both sides of the base plate 111. Mounting plates 114 are fixedly connected to the tops of the support columns 113. The casters 112 are equipped with brakes to secure the equipment after it reaches the designated position, preventing movement during material feeding. A leveling device is also provided on the base plate 111 to adjust the equipment's level according to ground conditions, ensuring stable operation. Multiple sets of mounting plates 114 are provided, with support columns 113 fixedly connected to both ends. The bottoms of the support columns 113 are fixedly connected to the base plate 111. Reinforcing ribs are provided between each set of mounting plates 114 to enhance the overall strength of the structure formed by the mounting plates 114 and support columns 113, enabling it to better bear the weight of the feeding assembly 120 and the auxiliary feeding mechanism 200. The height of each set of mounting plates 114 can be adjusted as needed to facilitate material feeding into the transmission cylinder 121.
[0031] The feeding assembly 120 includes a transmission cylinder 121, the bottom of which is fixedly mounted on the surface of the mounting plate 114. A conveying auger 122 is rotatably mounted inside the transmission cylinder 121, and a first motor 123 is connected to the end of the conveying auger 122. The first motor 123 is fixedly mounted on the transmission cylinder 121. A wear-resistant coating is applied to the surface of the blades of the conveying auger 122 to improve its wear resistance and extend its service life. The transmission cylinder 121 is inclined, with a feed inlet on the upper surface of the bottom end of the transmission wheel 212 and a discharge outlet on the lower surface of the top of the transmission cylinder 121. The inclination angle of the transmission cylinder 121 is adjustable to optimize material conveying. A leak-proof device is provided at the feed inlet of the transmission wheel 212 to prevent material leakage during entry.
[0032] Please see Figure 4 and Figure 5 The crushing component 210 includes a housing 213. A second motor 211 is provided on one side of the housing 213. The second motor 211 is installed on the upper surface of the middle part of the transmission cylinder 121. The second motor 211 is connected to the transmission wheel 212. The transmission wheel 212 is installed on one side of the housing 213 for limited rotation. The extrusion plate 215 is provided inside the housing 213. The fixing plate 218 is provided on the inner wall of the housing 213 and is correspondingly provided to the extrusion plate 215. The second motor 211 and the transmission wheel 212 are connected by a belt.
[0033] A drive shaft 214 is connected to the eccentric part of the drive wheel 212. The top of the extrusion plate 215 is connected to the drive shaft 214, and the bottom of the extrusion plate 215 is hinged to an auxiliary push plate 216. The other end of the auxiliary push plate 216 is hinged and supported inside the housing 213. A self-lubricating bearing is provided at the connection between the drive shaft 214 and the extrusion plate 215 to reduce frictional resistance and improve transmission efficiency. An adjustable limiting device is provided at the hinge between the auxiliary push plate 216 and the housing 213 to limit the swing angle of the auxiliary push plate 216, thereby controlling the movement amplitude of the extrusion plate 215.
[0034] An angle exists between the extrusion plate 215 and the fixing plate 218. Corresponding portions of the extrusion plate 215 and the fixing plate 218 have strip-shaped grooves. The surface of the fixing plate 218 has strip-shaped grooves that mate with it. A feeding hopper 219 is positioned directly above the extrusion plate 215 and the fixing plate 218, and is mounted on the housing 213. A rod is hinged to the center of the back of the extrusion plate 215, and a spring 217 is sleeved on the outside of the rod. One end of the spring 217 abuts against the upper limit of the auxiliary push plate 216. The other end of the spring 217 abuts against the outer end of the rod on the back of the extrusion plate 215. Spring seats are provided at corresponding positions on the auxiliary push plate 216 and the outer end of the rod on the back of the extrusion plate 215 to ensure a more stable installation of the spring 217 and prevent displacement during operation.
[0035] Working principle: When it is necessary to feed the silicon metal smelting furnace, the silicon metal raw material first enters the crushing component 210 of the auxiliary feeding mechanism 200 through the feeding hopper 219. The second motor 211 starts, driving the transmission wheel 212 to rotate within the housing 213. Since the transmission wheel 212 is eccentrically connected to the transmission shaft 214, when the transmission wheel 212 rotates, the transmission shaft 214 will drive the extrusion plate 215 to perform periodic reciprocating motion.
[0036] The top of the extrusion plate 215 is connected to the drive shaft 214, and the bottom is hinged to an auxiliary push plate 216. The other end of the auxiliary push plate 216 is hinged and supported inside the housing 213. When the extrusion plate 215 moves forward, the angle between it and the fixed plate 218 decreases, thus crushing the silicon metal material entering between them. The strip grooves on the extrusion plate 215 and the fixed plate 218 enhance the crushing effect, allowing the material to be crushed more thoroughly.
[0037] During the movement of the extrusion plate 215, the spring 217, which is hinged to the rod at the center of its back, plays a buffering and protective role. When the extrusion plate 215 is subjected to greater pressure, the spring 217 is compressed, absorbing some energy; when the pressure decreases, the spring 217 returns to its original shape, pushing the extrusion plate 215 to continue moving.
[0038] The crushed silicon metal raw material enters the transmission cylinder 121 through the feed inlet on the upper surface of the bottom end of the transmission cylinder 121. The first motor 123 starts, driving the conveying auger 122 to rotate within the transmission cylinder 121. Since the transmission cylinder 121 is inclined, the conveying auger 122 transports the crushed raw material from the bottom to the top of the transmission cylinder 121, and then into the silicon metal smelting furnace through the discharge outlet on the lower surface of the top.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
