Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and more specifically, to an automatic feeding glass furnace. Background Technology

[0002] Glass furnaces are the core equipment in glass production, used to melt raw materials such as quartz sand into molten glass at high temperatures. In the current process of feeding, the quartz sand bags need to be manually cut open and poured into the hopper. Operators directly contact the quartz sand with sharp edges, which poses safety risks such as scratches and dust inhalation. At the same time, manual pouring makes it difficult to empty the residual material in the bag, resulting in waste of raw materials. The residue also affects the quality of the glass after entering the furnace. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention proposes an automatic feeding glass melting furnace.

A bag-breaking and shaking component is provided inside the hopper. The conveyor belt is used to transport bags filled with quartz sand, and several support rods are rotatably arranged above the hopper to support the bags. When the conveyor belt drives the bag into the feeding end of the hopper, the trigger moves synchronously with the bag under the action of the guide, thereby triggering the bag-breaking and shaking component to penetrate from the bottom of the bag to break the bag and open the breaking part to shake the quartz sand in the bag into the hopper.

[0006] As a further embodiment of the present invention: the guide includes a side plate fixed to the side of the hopper, and an annular slide rail adapted to the trigger is provided on the side plate. The annular slide rail includes a pushing slide rail, an ascending slide rail, a resetting slide rail and a merging slide rail connected end to end. The trigger includes a lower plate and an upper plate that are movably connected. A pull cable connected to the bag breaking and shaking component is provided on the lower plate, and a baffle adapted to the material bag is provided on the upper plate.

[0008] As a further embodiment of the present invention: the bag-breaking and shaking component includes mounting plates symmetrically fixed on the inner walls of both sides of the hopper. The mounting plates are provided with vertical and horizontal sliding grooves that are spliced ​​together. A sliding table is movably mounted on the mounting plates. Sliding pins adapted to the vertical and horizontal sliding grooves are provided at both ends of the sliding table. One end of the sliding table is connected to a cable, and a sleeve rod is rotatably mounted on the other end of the sliding table. A blade is vertically mounted on the sleeve rod. A telescopic rod is slidably connected between the two sleeve rods. A tension spring connected to the telescopic rod is provided inside the sleeve rod.

[0009] As a further aspect of the present invention: a plurality of guide rollers are rotatably mounted on the inner wall of the hopper, the cable is wound around the guide rollers, and the height of the guide rollers is higher than the height of the transverse chute.

[0010] As a further embodiment of the present invention: a mixing component is rotatably arranged inside the furnace body, and a mixing motor for driving the mixing component is installed on the top of the furnace body; the mixing component includes a hollow rotating shaft connected to the output end of the mixing motor, and a plurality of mixing rods are arranged circumferentially at the lower end of the hollow rotating shaft; a screening component adapted to the mixing component is also provided on the top of the furnace body.

[0011] As a further aspect of the present invention: each mixing rod is provided with a plurality of air outlet holes communicating with the interior of the hollow rotating shaft, and a one-way valve plate is installed inside the hollow rotating shaft; the top of the furnace body is provided with a sleeve that wraps around the hollow rotating shaft, and an air cavity is formed between the sleeve and the hollow rotating shaft; the hollow rotating shaft is provided with a plurality of air inlet holes communicating with the air cavity, and an air inlet pipe is connected to the sleeve.

[0012] As a further embodiment of the present invention: the screening component includes a ball sleeve fixed on a hollow rotating shaft and a swaying disc movably sleeved on the ball sleeve.

A connecting frame is fixed on the hollow rotating shaft, and a push ball that abuts against the bottom surface of the swaying disc is provided on the connecting frame.

[0013] As a further aspect of the present invention: a flexible material screen is provided below the swing disk, and a sliding sleeve adapted to slide with the hollow rotating shaft is installed at the center of the flexible material screen.

[0014] The beneficial effects of this invention are: Driven by the trigger, the bag-breaking and shaking component first penetrates from the bottom of the bag to break it open. Then, it opens the broken part to both sides and generates a shaking action, which can quickly release the quartz sand and effectively shake off the quartz sand remaining on the inner wall of the bag, thus avoiding material waste. The support rod can rotate synchronously with the feeding of the bag while supporting it, which reduces frictional resistance and ensures that the bag enters the hopper smoothly. The sliding cooperation between the trigger and the guide makes the action of the bag breaking and shaking device precisely synchronized with the feeding stroke of the bag. The whole process is continuous and smooth, which is conducive to the continuous and stable feeding of the glass furnace. Quartz sand typically has sharp edges and corners, posing a risk of scratches when manually breaking or shaking the bags. This invention automates the bag-breaking and shaking process using a mechanical structure. Operators only need to place the bags on the conveyor belt, and subsequent processes are completed automatically in a closed or controlled state, significantly reducing the risk of workplace injuries and improving the working environment.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Please see Figure 1 and Figure 2This invention discloses an automatic feeding glass melting furnace, including a furnace body 100, on which a feeding inlet 110 is provided; a feeding unit 200 is provided on one side of the furnace body 100, the feeding unit 200 including a hopper 210, a conveyor belt 220 connected to the feeding end of the hopper 210, and a transfer component 230 connecting the discharge end of the hopper 210 and the feeding inlet 110; guide components 240 are symmetrically arranged on both sides of the hopper 210, and trigger components 250 are movably arranged on the guide components 240; a bag-breaking and shaking component 260 is provided inside the hopper 210; the conveyor belt 220 is used to convey the bag 270 filled with quartz sand. Several support rods 211 are rotatably arranged above the hopper 210 to support the bag 270. When the conveyor belt 220 drives the bag 270 into the feeding end of the hopper 210, the trigger 250 moves synchronously with the bag 270 under the action of the guide 240, thereby triggering the bag breaking and shaking component 260 to penetrate from the bottom of the bag 270 to break the bag 270 and open the breaking part to shake the quartz sand in the bag 270 into the hopper 210. Then the quartz sand in the hopper 210 is put into the furnace body 100 through the transfer component 230. Specifically, bags 270 filled with quartz sand are placed sequentially on conveyor belt 220, which transports the bags 270 toward hopper 210. As the conveyor belt 220 drives the bags 270 into hopper 210, the bottom of the bags 270 is supported by support rods 211, which rotate synchronously with the feeding of the bags 270. During the horizontal feeding of the bags 270, the bags 270 synchronously push the trigger 250 forward along the guide 240, thereby triggering the bag-breaking and shaking device 260 in hopper 210 to move upwards into hopper 210. The end opening extends to break open the material bag 270 and insert into it. As the material bag 270 is fed in, the bag-breaking and shaking component 260 gradually opens the bottom of the material bag 270, allowing the quartz sand inside the material bag 270 to automatically fall into the hopper 210. Then, the bag-breaking and shaking component 260 opens the breaking part to both sides and shakes the material bag 270 to shake off the remaining quartz sand inside the material bag 270, promoting the complete discharge of quartz sand into the hopper 210. Finally, the transfer component 230 feeds the quartz sand in the hopper 210 into the furnace body 100 through the feed inlet 110, thereby realizing automatic feeding of quartz sand.

[0020] It should be noted that the bag-breaking and shaking component 260 in this invention can penetrate from the bottom of the bag 270 and cut open the bag 270 when the bag 270 enters the hopper 210, thus achieving automatic bag breaking. After the bag is broken, the bag-breaking and shaking component 260 opens the breaking part and shakes the bag 270 to ensure that the quartz sand in the bag 270 can be completely shaken off and enter the hopper 210. Through the cooperation of the trigger component 250 and the guide component 240, the bag 270 can automatically trigger the action of the bag-breaking and shaking component 260 during the conveying process. The feeding of the bag 270 and the action of the bag-breaking and shaking component 260 are synchronized. After the bag is broken and the material is shaken, the quartz sand can be automatically put into the furnace body 100 through the transfer component 230 without manual intervention. Driven by the trigger 250, the bag-breaking and shaking component 260 first penetrates the bottom of the bag 270 to break it open. Then, it opens the broken part to both sides and generates a shaking action, which can quickly release the quartz sand and effectively shake off the quartz sand remaining on the inner wall of the bag 270, thus avoiding material waste. The support rod 211 can rotate synchronously with the feeding of the bag 270 while supporting the bag 270, which reduces frictional resistance and ensures that the bag 270 enters the hopper 210 smoothly; the sliding cooperation between the trigger 250 and the guide 240 makes the action of the bag breaking and shaking component 260 precisely synchronized with the feeding stroke of the bag 270, and the whole process is continuous and smooth, which is conducive to the continuous and stable feeding of the glass furnace. Quartz sand typically has sharp edges and corners, posing a risk of scratches when manually breaking or shaking the bags 270. This invention automates the bag-breaking and shaking process through a mechanical structure. Operators only need to place the bags 270 on the conveyor belt 220, and subsequent processes are automatically completed in a closed or controlled state, significantly reducing the risk of workplace injuries and improving the working environment.

[0021] In one embodiment, please refer to Figure 3 The transfer component 230 includes a feeding pipe 231 disposed at the bottom of the hopper 210. One end of the feeding pipe 231 is connected to the discharge end of the hopper 210, and the other end of the feeding pipe 231 is connected to the inlet 110. A transfer motor 232 is installed on the feeding pipe 231, and the output end of the transfer motor 232 is connected to a spiral blade 233 that is rotatably disposed inside the feeding pipe 231. Specifically, when the quartz sand falls into the hopper 210, the transfer motor 232 drives the spiral blades 233 to rotate, thereby driving the quartz sand in the hopper 210 into the feed pipe 231 and following the spiral blades 233 to move towards the feed inlet 110 until the quartz sand enters the furnace body 100 from the feed inlet 110, so as to realize the automatic feeding of quartz sand.

[0022] It is worth noting that by driving the spiral blades 233 to rotate in the feed pipe 231 through the transfer motor 232, the quartz sand is forcibly pushed, avoiding blockage or material interruption caused by poor fluidity or accumulation and stratification of the quartz sand. This ensures that the quartz sand can be continuously and evenly transferred from the hopper 210 to the feed inlet 110, thereby improving the stability of the glass furnace feeding. The feeding pipe 231 directly connects the discharge end of the hopper 210 to the feed port 110. The quartz sand moves within the closed pipe under the push of the spiral blades 233, effectively preventing dust overflow or material splashing during the transfer process. This reduces raw material loss, improves the working environment at the production site, and reduces the impact of dust on the health of operators. The rotational speed of the spiral blade 233 is independently controlled by the transfer motor 232. The feeding rate can be flexibly adjusted according to the melting speed of the furnace body 100 or the amount of material accumulated in the hopper 210, which realizes precise control of the amount of quartz sand fed, which is conducive to stabilizing the melting conditions in the furnace and improving the quality consistency of glass products.

[0023] Further, please refer to Figure 3 , Figure 4 and Figure 5 The guide 240 includes a side plate 241 fixed to the side of the hopper 210. The side plate 241 is provided with an annular slide that is adapted to the trigger 250. The annular slide includes a pushing slide 242, a rising slide 243, a resetting slide 244, and a merging slide 245 connected end to end. The trigger 250 includes a lower plate 251 and an upper plate 252 that are movably connected. The lower plate 251 is provided with a pull cable 257 that is connected to the bag breaking and shaking component 260. The upper plate 252 is provided with a baffle 259 that is adapted to the bag 270. Specifically, in the initial state, the lower plate 251 and the upper plate 252 are attached to each other and located at the connection between the pushing slide 242 and the merging slide 245. As the bag 270 enters the hopper 210, the bag 270 pushes the baffle 259, thereby causing the lower plate 251 and the upper plate 252 to move forward along the pushing slide 242 as a whole. This causes the bag breaking and shaking component 260 to break and shake the bag 270 through the cable 257. When the bag 270 is completely inside the hopper 210, the lower plate 251 and the upper plate 252 just reach the connection between the pushing slide 242 and the rising slide 243. Then, the upper plate 252 separates from the lower plate 251 and moves upward along the rising slide 243, causing the baffle 259 to detach from the bag 270. When the trigger 250 reaches the connection between the rising slide 243 and the reset slide 244, the upper plate 252 can automatically slide and reset along the inclined reset slide 244 to the upper end of the merging slide 245. At the same time, the lower plate 251 also retracts along the pushing slide 242 to the connection between the pushing slide 242 and the merging slide 245. Finally, the upper plate 252 slides down along the merging slide 245 again and fits against the lower plate 251 to realize the overall reset of the trigger 250, while driving the bag breaking and shaking component 260 to retract into the hopper 210.

[0024] It should be noted that the guide 240 achieves the orderly movement of the trigger 250 by setting the push slide 242, the rise slide 243, the reset slide 244 and the merge slide 245; the annular slide enables the trigger 250 to complete the bag breaking, material shaking and reset actions according to the preset trajectory, ensuring the automation and continuity of the whole process. The trigger 250 includes a lower plate 251 and an upper plate 252 that are movably connected. The lower plate 251 is connected to the bag-breaking and shaking component 260 via a cable 257. The upper plate 252 is equipped with a baffle 259 that is compatible with the bag 270. This split design allows the trigger 250 to be flexibly separated and combined at different stages, enabling precise control of the bag-breaking and shaking component 260. This allows the bag-breaking and shaking component 260 to automatically shake the quartz sand out of the bag 270 completely, avoiding quartz sand residue and improving the utilization rate of quartz sand. The action of the trigger 250 directly drives the bag-breaking and shaking component 260 to complete the bag breaking and shaking actions through the cable 257, which not only simplifies the control logic but also improves the system's response speed and reliability. The guide 240 adopts a closed-loop trajectory consisting of a push slide 242, a rise slide 243, a reset slide 244, and a merging slide 245 connected end to end. Combined with the split design of the lower plate 251 and the upper plate 252, the trigger 250 can automatically return to the initial position along the slide and re-fit with the lower plate 251 after completing one bag breaking action. The reset is achieved entirely by the slide direction and gravity. After the upper plate 252 reaches the end of the push slide 242, it separates from the lower plate 251 and is lifted along the rising slide 243, so that the baffle 259 can be released from the unloaded bag 270 in time. This prevents the bag 270 from being dragged or pulled by the trigger 250, and also avoids the baffle 259 from getting stuck in the empty bag and affecting subsequent actions, thus ensuring the smoothness of process switching. The cable 257 connects the lower plate 251 to the bag breaking and shaking component 260. During the movement of the trigger component 250 along the push slide 242, the pulling stroke of the cable 257 strictly corresponds to the feeding distance of the bag 270, so that the extension, tearing, spreading and shaking actions of the bag breaking and shaking component 260 are matched with the position of the bag 270, realizing precise timing control under mechanical linkage. The entire triggering, separation and reset process is completed entirely by relying on the geometry of the slide and the weight of the component, so that it can maintain high reliability under harsh working conditions such as high temperature and dust.

[0025] Furthermore, please refer to Figure 6 In order to achieve automatic separation and automatic merging of the lower plate 251 and the upper plate 252, a cavity 253 is provided in the lower plate 251, and a first guide rod 254 is vertically fixed in the cavity 253. The upper plate 252 is slidably sleeved on the first guide rod 254. A first spring 255 is provided in the cavity 253 to abut against the upper plate 252. An electromagnet 256 adapted to the upper plate 252 is installed on the upper end face of the lower plate 251. Specifically, when the bag 270 pushes the baffle 259 forward, the lower plate 251 and the upper plate 252 move forward together along the sliding slide 242 until the lower plate 251 and the upper plate 252 reach the connection between the sliding slide 242 and the rising slide 243. At this time, the upper plate 252 is no longer restricted by the sliding slide 242 and can move upward along the first guide rod 254 under the elastic force of the first spring 255, so that the upper plate 252 slides upward along the rising slide 243 to achieve temporary separation between the upper plate 252 and the lower plate 251. At this time, the baffle 259 also rises with the upper plate 252 and separates from the bag 270, so that the empty bag 270 after unloading the quartz sand can be moved out from the side of the hopper 210 away from the conveyor belt 220. Subsequently, the upper plate 252 slides and resets along the inclined reset slide 244 under the action of gravity, driving the lower plate 251 to slide and reset synchronously along the push slide 242 until the upper plate 252 slides to the connection between the merging slide 245 and the reset slide 244. At this time, the lower plate 251 also just slides to the connection between the merging slide 245 and the push slide 242. Finally, the electromagnet 256 is energized to attract the upper plate 252, causing the upper plate 252 to slide down along the merging slide 245 again until it is in contact with the lower plate 251. The first spring 255 is compressed, and at the same time, the baffle 259 also drops to the initial height so that the entire trigger 250 can be fed again along the push slide 242 under the push of the next material bag 270.

[0026] It is worth noting that when the upper plate 252 moves to the end of the push slide 242 along with the lower plate 251, the constraint above the upper plate 252 is released, and the first spring 255 automatically lifts it up along the first guide rod 254, so that the baffle 259 quickly disengages from the empty material bag 270 that has completed unloading, ensuring that the empty material bag 270 can be discharged from the other side of the hopper 210 without obstruction, effectively preventing the empty bag from getting tangled or dragging the trigger 250, and ensuring the smoothness of process switching; After the upper plate 252 is separated, it first slides back to its original position along the reset slide 244 by gravity. Then, the electromagnet 256 is energized and attracted, so that the upper plate 252 overcomes the elastic force of the first spring 255 and slides down precisely along the merging slide 245 to fit with the lower plate 251, restoring the entire trigger 250 to its initial standby state. This ensures the reliability of the reset and realizes the timing controllability of the reset action. Electromagnet 256 is only briefly energized and engaged during the reset phase, and remains de-energized during the rest of the time. It relies on mechanical structure and spring force to complete the separation and most of the reset stroke, thus avoiding the reliability issues caused by the overheating of electromagnet 256 during prolonged energization. It is suitable for continuous production conditions. After completing one bag breaking and shaking operation, the trigger 250 can quickly and automatically reset and enter the standby position, allowing the feeding unit 200 to seamlessly connect with the feeding of the next bag 270 without manual intervention or machine downtime. This effectively shortens the feeding interval and improves the continuity of glass furnace feeding and overall production efficiency.

[0027] Furthermore, considering that during the reset process, the upper plate 252 and the lower plate 251 are slidably reset solely by the weight of the upper plate 252 itself, the smoothness of the reset process may be affected by significant moving resistance. Therefore, please refer to [the relevant documentation / reference needed]. Figure 5 and Figure 6 A second guide rod 246 is horizontally fixed inside the sliding track 242, and the lower plate 251 is slidably sleeved on the second guide rod 246. A second spring 247 that abuts against the lower plate 251 is movably sleeved on the second guide rod 246. Specifically, when the lower plate 251 and the upper plate 252 move synchronously along the push slide 242 with the material bag 270, the second spring 247 will be compressed and stored. When they reach the connection between the push slide 242 and the rising slide 243, the upper plate 252 and the lower plate 251 separate, and the entire trigger 250 is no longer restricted by the material bag 270. The lower plate 251 can then automatically slide back to its original position along the push slide 242 under the elastic force of the second spring 247, while simultaneously driving the upper plate 252 to slide back to its original position along the reset slide 244.

[0028] It should be noted that the second spring 247 is compressed and stores energy when the lower plate 251 moves forward with the material bag 270. When the trigger 250 separates from the material bag 270, the second spring 247 releases its elastic force and actively pushes the lower plate 251 to slide and reset along the sliding slide 242. This effectively compensates for the resistance that may be caused by slide friction, dust adhesion or component misalignment when resetting along the reset slide 244 by relying solely on the gravity of the upper plate 252, ensuring that the reset action is reliable and smooth. While the lower plate 251 is reset under the drive of the second spring 247, the upper plate 252 is driven to slide synchronously along the reset slide 244 through the cable 257 or other linkage, so that the upper and lower plates maintain coordinated movement during the reset phase, avoiding jamming or misalignment caused by asynchronous reset, and ensuring that the trigger 250 as a whole can accurately enter the initial standby state in the next cycle. The environment for feeding quartz sand is usually subject to adverse factors such as dust and debris. The surface of the slide may increase friction due to dust accumulation. The active thrust provided by the second spring 247 can effectively overcome such external interference, so that the reset process no longer relies excessively on the smoothness of the slide and the weight of the components, thus improving the stability and reliability of the mechanism in long-term continuous operation. The active reset mechanism accelerates the overall process of the trigger 250 from completing the bag breaking and shaking to returning to standby mode, shortens the process interval time, and enables the feeding unit 200 to continuously process multiple bags of quartz sand at a faster pace, further improving the feeding efficiency of the glass furnace.

[0029] In yet another embodiment, please refer to Figure 7 The bag-breaking and shaking component 260 includes mounting plates 261 symmetrically fixed to the inner walls of both sides of the hopper 210. The mounting plates 261 have vertical sliding grooves 262 and horizontal sliding grooves 263 that are spliced ​​together. A slide table 264 is movably mounted on the mounting plates 261. The slide table 264 has sliding pins 265 at both ends that are adapted to the vertical sliding grooves 262 and horizontal sliding grooves 263. One end of the slide table 264 is connected to a cable 257. A sleeve rod 266 is rotatably mounted on the other end of the slide table 264. A blade 268 is vertically mounted on the sleeve rod 266. A telescopic rod 267 is slidably connected between the two sleeve rods 266. A tension spring (not shown in the figure) connected to the telescopic rod 267 is provided inside the sleeve rod 266. Specifically, in the initial state, the slide table 264 is in a vertical position, and the sliding pins 265 at both ends of the slide table 264 are located in the vertical groove 262. When the trigger 250 follows the horizontal feeding of the material bag 270, the slide table 264 can be pulled by the cable 257. The slide table 264 can move upward along the vertical groove 262 under the action of the vertical component force generated by the cable 257, and at the same time drive the blades 268 on both sides to rise synchronously, so that the blades 268 can be inserted into the material bag 270 from the bottom of the material bag 270. As the material bag 270 is fed horizontally, the blades 268 gradually cut out the discharge cut at the bottom of the material bag 270. As the trigger 250 continues to feed, the upper sliding pin 265 of the slide table 264 gradually transitions from the vertical slide groove 262 to the horizontal slide groove 263, until the lower sliding pin 265 of the slide table 264 also transitions to the horizontal slide groove 263. Then, under the action of the horizontal component force of the cable 257, the slide table 264 slides horizontally along the horizontal slide groove 263, causing the two slide tables 264 to gradually move away from each other in the horizontal direction. At the same time, the telescopic rod 267 extends from the sleeve rods 266 on both sides, and the tension spring is stretched and stored, thereby realizing that the two blades 268 move away from each other in the horizontal direction. The blades 268 moving away from each other open the cut at the bottom of the bag 270 to both sides, so as to promote the discharge of quartz sand inside the bag 270 and produce a shaking effect on the bag 270 to avoid quartz sand residue. When the material discharge is completed, the trigger 250 resets, the cable 257 stops pulling the slide 264, and the two slides 264 can approach each other under the pull of the tension springs on both sides until the sliding pins 265 at both ends of the slide 264 re-enter the vertical slide groove 262. Then the two slides 264 can fall down and reset along the vertical slide groove 262 under the action of gravity, so that the two blades 268 retract into the hopper 210. The bag-breaking and shaking component 260, through the cooperation of the slide table 264 with the vertical slide groove 262 and the horizontal slide groove 263, realizes the vertical insertion and horizontal opening of the blade 268. Under the traction of the cable 257, the slide table 264 first raises and inserts the blade 268 into the bag 270, then horizontally opens the bottom cut of the bag 270 and shakes the bag 270 to ensure that the quartz sand is completely discharged. Through the design of the telescopic rod 267 and the tension spring, the horizontal opening and resetting of the blade 268 are realized, further optimizing the shaking effect and reducing the residue of quartz sand.

[0030] It should be noted that, under the traction of the cable 257, the slide table 264 first rises along the vertical slide groove 262, so that the blade 268 is vertically inserted from the bottom of the material bag 270; then the sliding pin 265 transitions to the horizontal slide groove 263, and the horizontal component of the cable 257 drives the two slide tables 264 to move away from each other, which opens the cut laterally and generates vibration. The bag-breaking and shaking component 260 relies entirely on the chute geometry, spring force, and gravity to complete insertion, opening, shaking, and reset. It eliminates the need for electrical components such as sensors, cylinders, or motors that are susceptible to dust and high temperatures, thus improving long-term operational stability and durability in quartz sand feeding environments. Guided by the transverse groove 263, the blades 268 on both sides gradually move away, fully opening the bottom cut of the material bag 270 to form a large opening for the rapid discharge of quartz sand; at the same time, the cooperation between the telescopic rod 267 and the tension spring generates elastic energy storage and release during the opening process, which forms a high-frequency micro-vibration on the material bag 270, effectively shaking off the quartz sand adhering to the bag wall and greatly reducing material residue. After the material is discharged, the tension of the cable 257 is released, and the tension spring automatically pulls the two slides 264 back and together. The sliding pin 265 retracts along the horizontal slide 263 to the entrance of the vertical slide 262. Under the action of gravity, the slide 264 falls down along the vertical slide 262 to reset. The blade 268 retracts into the hopper 210. The entire reset process is completed automatically, making full preparations for the bag breaking operation of the next bag 270. The blade 268 cuts only from the bottom center and spreads out to both sides, resulting in a neat cut without producing fragments. The material bag 270 remains relatively intact, making it easy to collect and process after unloading, reducing the on-site mess and secondary cleaning burden caused by empty bags scattering.

[0031] Furthermore, in order for the cable 257 to drive the slide table 264 to first rise vertically along the vertical slide groove 262 and then slide laterally along the horizontal slide groove 263, it is necessary to ensure that the cable 257 can always apply an upward tension to the slide table 264; for this purpose, please refer to... Figure 3 A plurality of guide rollers 258 are rotatably mounted on the inner wall of the hopper 210, and the cable 257 is wound around the guide rollers 258. The height of the guide rollers 258 is higher than the height of the transverse chute 263. In this way, since the guide roller 258 is higher than the transverse chute 263, the tension generated by the cable 257 on the slide table 264 can always be decomposed into a vertical component and a horizontal component. When the slide table 264 is located in the vertical chute 262, the vertical component can drive the slide table 264 to rise vertically. When the slide table 264 reaches the transition point between the vertical chute 262 and the transverse chute 263, the horizontal component can drive the slide table 264 to smoothly enter the transverse chute 263 from the vertical chute 262 and continue to move along the transverse chute 263.

[0032] It is worth noting that the guide roller 258 adjusts the traction direction of the cable 257 to be obliquely upward, so that the force exerted by the cable 257 on the slide table 264 is always decomposed into a vertical component and a horizontal component. When the sliding pin 265 is located in the vertical slide groove 262, the vertical component mainly drives the slide table 264 to rise; when the sliding pin 265 transitions to the horizontal slide groove 263, the horizontal component mainly drives the slide table 264 to move laterally. At the critical point where the sliding pin 265 transitions from the vertical slide groove 262 to the horizontal slide groove 263, the oblique traction force of the cable 257 remains constant, and its horizontal component can naturally push the slide table 264 into the horizontal slide groove 263, rather than relying on inertia or external force intervention. This effectively avoids jamming or stopping caused by improper direction of driving force during trajectory switching, and ensures the continuity of bag breaking and opening actions. The guide roller 258 is fixedly installed on the inner wall of the hopper 210. Its height position is preset according to the position of the transverse slide 263, so that the traction angle of the cable 257 remains constant during the operation of the equipment. This ensures that the movement trajectory of the slide table 264 is consistent in each working cycle, eliminates the action deviation caused by angle fluctuation, and improves the reliability of the mechanism in long-term continuous operation. The guide roller 258 is installed in a rotating manner. During the winding process, the cable 257 drives the guide roller 258 to rotate synchronously, which converts sliding friction into rolling friction, greatly reducing the wear between the cable 257 and the contact surface. At the same time, it reduces the traction resistance, making the tension loss transmitted from the trigger 250 to the cable 257 smaller, and ensuring the sensitivity and durability of the bag breaking and shaking component 260.

[0033] In further embodiments, please refer to Figure 8 A mixing component 130 is rotatably arranged inside the furnace body 100, and a mixing motor 120 for driving the mixing component 130 is installed on the top of the furnace body 100; a screening component 140 adapted to the mixing component 130 is also provided on the top of the furnace body 100; when the mixing motor 120 drives the mixing component 130 to rotate, the screening component 140 is synchronously driven by the mixing component 130 to perform circumferential screening of the quartz sand falling from the feed inlet 110, intercepting larger particles and impurities in the quartz sand; Further, please refer to Figure 9 The mixing component 130 includes a hollow rotating shaft 131 connected to the output end of the mixing motor 120, and a plurality of mixing rods 132 are circumferentially arranged at the lower end of the hollow rotating shaft 131. The mixing motor 120 drives the hollow rotating shaft 131 to rotate circumferentially, thereby driving each mixing rod 132 to move synchronously, so as to stir the molten glass in the furnace body 100, accelerate the melting process, and improve the uniformity of the finished product.

[0034] It should be noted that, in order to adapt to the internal environment of the furnace, the hollow rotating shaft 131 and the mixing rod 132 can be made of platinum-rhodium alloy (such as Pt-10Rh, Pt-20Rh) or platinum-rhodium-zirconium composite system. Such materials have excellent chemical inertness at high temperatures, can effectively resist the corrosion of glass melt (especially alkali metal oxides), and do not contaminate the glass melt. The screen 140 is located at the top inside the furnace body 100. It mainly comes into contact with solid or semi-molten quartz sand during the falling process. The working temperature is relatively low (about 500–800℃), but it needs to withstand the impact and friction of quartz sand and has certain heat resistance and oxidation resistance. It is made of high-chromium heat-resistant cast iron (such as Cr25Ni20) or heat-resistant cast steel (such as ZG40Cr25Ni20Si2). These materials have excellent oxidation resistance and thermal fatigue resistance at high temperatures. At the same time, they have high surface hardness and can effectively resist the continuous erosion and wear of quartz sand. Driven by the mixing motor 120, the screening component 140 rotates synchronously with the mixing component 130 to screen the quartz sand falling from the feed inlet 110 in a circumferential manner. This effectively intercepts large quartz sand particles that exceed the particle size limit and any impurities that may be mixed in (such as packaging debris, impurities, etc.) before the quartz sand enters the melting zone, thus avoiding problems such as uneven melting, blockage of the discharge port, or impact on the quality of the finished product after these foreign objects enter the melt. By intercepting large particles and impurities in advance, the screening component 140 effectively reduces the presence of foreign matter inside the furnace body 100. Combined with the continuous stirring of the molten glass by the mixing rod 132, it can accelerate heat conduction and component diffusion, making the melt composition more uniform and the reaction more complete, thereby improving the transparency, strength and finished product consistency of glass products. During continuous feeding, the screen 140 always maintains a circumferential rotating screening state, effectively processing each batch of falling quartz sand, avoiding the problems of missed screening or accumulation that may occur during intermittent screening. The continuous and stable screening and stirring together ensure the long-term stability of the internal working conditions of the furnace, providing reliable support for continuous production.

[0035] Furthermore, to improve the quality of the finished glass product during the glass melting process, please refer to [link / reference needed]. Figure 9 and Figure 10 Each mixing rod 132 has several air outlets 133 that communicate with the interior of the hollow rotating shaft 131. A one-way valve plate 134 is installed inside the hollow rotating shaft 131. The top of the furnace body 100 is provided with a sleeve 101 that wraps around the hollow rotating shaft 131. An air cavity 102 is formed between the sleeve 101 and the hollow rotating shaft 131. Several air inlets 135 that communicate with the air cavity 102 are provided on the hollow rotating shaft 131. An air inlet pipe 103 is connected to the sleeve 101. Specifically, during the mixing process, the hollow rotating shaft 131 drives the mixing rod 132 to rotate, and an inert gas (such as nitrogen or argon) is introduced into the housing 101 through the air inlet pipe 103. Then, the inert gas enters the hollow rotating shaft 131 through the air inlet hole 135. The one-way valve plate 134 opens in one direction, allowing the inert gas to enter each mixing rod 132 through the one-way valve plate 134 and be discharged from the corresponding air outlet hole 133. This allows the inert gas to fully contact and fuse with the molten glass during the mixing process. Through the large flow rate of nitrogen bubbles, the mechanical disturbance of the rising bubbles is used to forcibly break the stagnant layer and temperature boundary layer in the melt, forming a nitrogen curtain above the liquid surface. This isolates water vapor and carbon dioxide, preventing them from causing "surface hydroxylation" or forming a silicon-rich layer on the surface of the glass melt, thus avoiding the appearance of streaks on the surface of the optical glass.

[0036] It is worth noting that while the mixing rod 132 is mechanically stirring the molten glass, it continuously releases a large number of fine inert bubbles from the vent 133. The bubbles generate strong mechanical disturbances during their ascent, forcibly breaking the stagnant layer and temperature boundary layer inside the melt, so that the glass melt is efficiently mixed at both the macroscopic and microscopic scales, accelerating the melting reaction process and improving the uniformity and stability of the glass melt. The inert gas escaping from the inside of the melt continuously forms a dense protective gas curtain above the liquid surface, effectively preventing the residual water vapor and carbon dioxide in the furnace from contacting the surface of the glass melt, avoiding the "surface hydroxylation" phenomenon and the formation of a silicon-rich layer, thereby eliminating the "striped skin" defect that is very easy to occur on the surface of optical glass and high-end electronic glass, and improving the surface quality and optical performance of the finished product. As the rising inert bubbles pass through the melt, they can adsorb and carry fine impurities, unmelted particles, and trace amounts of gas, bringing them to the surface where they are released or accumulated in the scum on the surface as the bubbles burst. This facilitates subsequent slag removal, further purifies the glass melt, reduces internal inclusions and porosity defects, and improves the intrinsic quality of the finished product.

[0037] Additionally, please see Figure 8 and Figure 11 The screening component 140 includes a ball sleeve 141 fixed on a hollow rotating shaft 131 and a swing disk 142 movably sleeved on the ball sleeve 141. The upper end face of the swing disk 142 is connected to the inner top wall of the furnace body 100 by several elastic ropes 143. A surrounding plate 145 is provided around the swing disk 142. Several through slots 144 are opened circumferentially on the swing disk 142, and a screen is provided in the through slots 144. A connecting frame 148 is fixed on the hollow rotating shaft 131, and a push ball 149 that abuts against the bottom surface of the swing disk 142 is provided on the connecting frame 148. When the hollow rotating shaft 131 rotates, it can drive the connecting frame 148 and the push ball 149 to move synchronously in a circumferential direction. The push ball 149 pushes the swing disk 142 upward, so that the contact position between the swing disk 142 and the push ball 149 is tilted upward. With the circumferential movement of the push ball 149, the swing disk 142 can realize the overall circumferential reciprocating swing motion, which can shake the powdered quartz sand that falls on the swing disk 142, so that the quartz sand can be evenly spread on the entire swing disk 142, and the quartz sand can be screened through various screens to ensure the overall uniformity of the quartz sand and the impurity removal effect.

[0038] It is worth noting that the swaying screening action of the screening component 140 is entirely driven by the hollow rotating shaft 131 of the mixing component 130. Through the periodic contact between the push ball 149 and the bottom surface of the swaying disk 142, the rotational motion is converted into circumferential reciprocating swaying. When the push ball 149 rotates circumferentially with the hollow rotating shaft 131, it lifts the parts of the swaying disk 142 upward in sequence. With the elastic reset of the elastic rope 143, the swaying disk 142 generates a swaying compound motion, which can spread the quartz sand falling on it evenly in all directions under the combined action of centrifugal force and gravity, so that the material thin layer covers the entire screen surface, improving the screening area utilization rate and screening efficiency. The swaying disc 142 is flexibly suspended on the inner top wall of the furnace body 100 by the elastic rope 143. When it comes into contact with the push ball 149, it generates elastic deformation and stores energy. After it leaves the contact, it quickly rebounds and resets, forming a high-frequency micro-amplitude vibration superimposed on the circumferential swaying, which effectively prevents the quartz sand from clogging or sticking on the screen surface. After being screened on the swaying disc 142, the qualified fine material falls into the furnace body 100 through the screen in the channel 144, while large particles of quartz sand or impurities are intercepted on the screen surface and gather towards the edge of the enclosure plate 145 under the action of swaying, which is convenient for centralized cleaning or periodic discharge. This realizes the integration of material purification and feeding, and avoids impurities from entering the melting zone and affecting the glass quality.

[0039] Please see Figure 11 In order to further improve the screening effect, a flexible material screen 146 is provided below the swing disk 142, and a sliding sleeve 147 that is slidably adapted to the hollow rotating shaft 131 is installed at the center of the flexible material screen 146. When the swaying disc 142 oscillates in a circumferential direction, it can drive the flexible material screen 146 below to sway and shake synchronously, thereby enabling the quartz sand falling from the swaying disc 142 to be screened again. The rotation of the hollow rotating shaft 131 enables the dynamic oscillation of the swaying disc 142. Combined with the secondary screening of the flexible material screen 146, this effectively reduces the agglomeration and local accumulation of powdered quartz sand, ensuring the uniform distribution of quartz sand throughout the furnace body 100. The uniform spreading and screening of quartz sand reduces local overheating or incomplete reaction caused by uneven distribution of quartz sand during the reaction process. It also screens and disperses large particles or agglomerates in the quartz sand, reducing waste caused by uneven distribution of quartz sand, improving the utilization rate of quartz sand, and enhancing reaction efficiency and product quality.

[0040] It should be noted that the swaying disc 142 serves as the first-stage screening, intercepting large particles of quartz sand and coarse impurities; the flexible material screen 146 serves as the second-stage screening, further refining the material passing through the swaying disc 142; the two-stage screening works together to effectively remove excessive particles and agglomerates, ensuring that the quartz sand entering the 100-degree melting zone of the furnace has a uniform particle size and high purity. The flexible screen 146 slides with the hollow rotating shaft 131 through the sliding sleeve 147, and directly relies on the circumferential reciprocating oscillation of the swaying plate 142 to generate synchronous shaking, so that the movement rhythm of the two screen surfaces is consistent. The material falls layer by layer under the action of gravity and is continuously screened, avoiding material accumulation or screening interruption caused by asynchronous movement, and improving the smoothness and reliability of screening operation. The flexible screen 146 generates elastic deformation and micro-vibration during the swinging process, which can continuously disturb the quartz sand powder on the screen surface and effectively break the powder agglomeration and bridging caused by static electricity, moisture or extrusion. At the same time, the combined swinging of the double-layer screen surface makes the material continuously redistributed in the horizontal direction, completely eliminating local accumulation and realizing the uniform dispersion of quartz sand in the furnace body 100. When uniformly spread and consistent-sized quartz sand enters the melting zone, it has a larger heating area and a shorter heat transfer path, enabling it to reach the melting temperature quickly and evenly. This effectively avoids problems such as local overheating, undermelting, or incomplete reaction caused by material concentration or particle size differences. It not only shortens the melting cycle but also ensures the homogeneity of the glass melt from the source, improving the light transmittance, mechanical strength, and batch stability of the finished product.

The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
