[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0020] Refer to Figures 1-4 , a quartz sand melting device provided in this embodiment includes: The furnace body 1 is configured to rotate around a horizontal axis. By rotating around the horizontal axis, the furnace body 1 improves the heat uniformity of quartz sand melting and ensures the quality of quartz sand melting; The storage bin 3 is located directly above the furnace body 1. The bottom wall of the storage bin 3 is provided with a discharge port, and a discharge valve is arranged on the discharge port. When the discharge valve is opened, the quartz sand in the storage bin 3 is discharged; The feeding bin 4 is located between the storage bin 3 and the furnace body 1 and is configured to reciprocate horizontally. The feeding bin is used to receive the quartz sand discharged from the storage bin 3 and disperse the quartz sand into the furnace body 1 during the reciprocating movement. Two groups of feeding chutes 5 are opened at both ends of the bottom wall of the feeding bin 4. The two groups of feeding chutes 5 cooperate to complete the dispersed feeding of quartz sand. The feeding chute 5 on the left side completes the feeding of quartz sand to the left half of the furnace body 1, and the feeding chute 5 on the right side completes the feeding of quartz sand to the right half of the furnace body 1; The rack 6 is fixedly arranged along the moving direction of the feeding bin 4; The conveyor belt 7 is rotatably arranged in the feeding box 4. Both ends of the conveyor belt 7 are respectively located above the two groups of feeding troughs 5. When the conveyor belt 7 moves with the feeding box 4, it is driven by the rack 6 to rotate so as to convey the received quartz sand to the position of the feeding trough 5.

[0021] During operation, the quartz sand in the storage box 3 falls onto the conveyor belt 7 in the feeding box 4. The feeding box 4 adjusts the positions of the two feeding troughs 5 relative to the furnace body 1 by reciprocating movement. And through the arrangement of the rack 6, during the reciprocating movement of the feeding box 4, the conveyor belt 7 is driven by the rack 6 to rotate. When the conveyor belt 7 rotates, the quartz sand falling on it is conveyed to one of the feeding troughs 5. The quartz sand is fed into the furnace body 1 through this feeding trough 5. Through the cooperation of the two feeding troughs 5, the feeding dispersion range of the quartz sand can be expanded.

[0022] Specifically, referring to Figure 3 and Figure 4 , in this embodiment, a moving driving mechanism is provided on the bottom wall of the storage box 3. The moving driving mechanism includes a support 8, a moving motor 9, a moving lead screw 10 and a moving slide bar 11. The support 8 is fixedly arranged on the bottom wall of the storage box 3. The moving motor 9 is fixedly arranged on the support 8. The moving lead screw 10 is rotatably arranged on the support 8. One end of the moving lead screw 10 is connected to the output end of the moving motor 9. The moving slide bar 11 is fixedly arranged on the support 8. One side of the feeding box 4 is connected to the moving lead screw 10 by a thread, and the other side of the feeding box 4 is slidably arranged on the moving slide bar 11. Under the drive of the moving lead screw 10 and the guiding action of the moving slide bar 11, the feeding box 4 is driven to move below the storage box 3.

[0023] Specifically, referring to Figures 3-5 , in this embodiment, the conveyor belt 7 includes a belt body 12 and two groups of drive shafts 13. The two groups of drive shafts 13 are respectively rotatably arranged on the side walls at both ends of the feeding box 4. The drive shafts 13 penetrate through the side walls of the feeding box 4 and extend outside the feeding box 4. Both ends of the belt body 12 are sleeved on the drive shafts 13. Drive gears 14 are fixedly arranged on the drive shafts 13. A transmission shaft 15 is rotatably arranged on the side wall of the feeding box 4. A transmission gear 16 is fixedly arranged on the transmission shaft 15. The transmission gear 16 is located between the rack 6 and the drive gear 14, and the transmission gear 16 meshes with the rack 6 and the drive gear 14.

[0024] During operation, when the loading box 4 reciprocates under the drive of the moving lead screw 10, the transmission gear 16 meshes with the rack 6 and rotates. The transmission gear 16 drives the drive gear 14 to rotate, and the drive gear 14 drives the drive shaft 13 to drive the conveyor belt 7 to rotate. The conveyor belt 7 conveys the received quartz sand into a group of loading troughs 5 to complete the loading of the quartz sand. Moreover, as the moving direction of the loading box 4 is adjusted, the conveying direction of the conveyor belt 7 also changes accordingly, so as to realize the alternate loading of quartz sand into the two groups of loading troughs 5. The overall loading principle is that one group of loading troughs 5 on the left completes the loading of quartz sand into the left half of the furnace body 1, and one group of loading troughs 5 on the right completes the loading of quartz sand into the right half of the furnace body 1. For example, in this embodiment, when the loading box 4 moves to the right, the transmission gear 16 rotates clockwise. The transmission gear 16 drives the conveyor belt 7 to rotate counterclockwise through the drive gear 14. The quartz sand is conveyed by the conveyor belt 7 to the left loading trough 5 and is loaded through the left loading trough 5. The left loading trough 5 completes the dispersed loading of quartz sand into the left half of the furnace body 1. When the loading box 4 moves to the left, the transmission gear 16 rotates counterclockwise. The transmission gear 16 drives the conveyor belt 7 to rotate clockwise through the drive gear 14. The quartz sand is conveyed by the conveyor belt 7 to the right loading trough 5 and is loaded through the right loading trough 5. The right loading trough 5 completes the dispersed loading of quartz sand into the left half of the furnace body 1. Through the cooperation of the two groups of loading troughs 5, the range of dispersed loading of quartz sand is expanded.

[0025] As an alternative embodiment, there is no need to provide the transmission shaft 15 and the transmission gear 16. The drive gear 14 is directly meshed with the rack 6. In this connection mode, when the loading box 4 moves to the right, the conveyor belt 7 is directly driven by the drive gear 14 to rotate clockwise, and the quartz sand is loaded through the right loading trough 5. When the loading box 4 moves to the left, the conveyor belt 7 is directly driven by the drive gear 14 to rotate counterclockwise, and the quartz sand is loaded through the left loading trough 5.

[0026] And as a preferred embodiment, two groups of drive gears 14 are symmetrically provided at both ends of the drive shaft 13. The rack 6 and the transmission gear 16 are both correspondingly arranged with the drive gears 14. The setting of the two groups of drive gears 14 further ensures the stability of the rotation and conveyance of the conveyor belt 7.

[0027] Specifically, referring to Figure 3 , in this embodiment, the two groups of loading troughs 5 are always located above the inner cavity of the furnace body 1 to ensure that the quartz sand can be accurately loaded into the furnace body 1 through the loading troughs 5 when the loading box 4 reciprocates; The length of the loading box 4 is greater than 1 / 2 of the moving lead screw 10. When the loading box 4 moves to one end of the moving lead screw 10, the other end of the loading box 4 is still located below the storage box 3, ensuring that the loading box 4 can always receive the quartz sand from the storage box 3.

[0028] Specifically, referring to Figure 1 andFigure 6 In this embodiment, a plurality of convex plates 17 are fixedly provided on the outer edge of the upper end of the furnace body 1.

[0029] During operation, the fixed pressing plate 19 corresponds to the through gap 18. The furnace cover 2 is placed on the furnace body 1. The position of the furnace cover 2 is adjusted by rotation. The fixed pressing plate 19 is adjusted from the through gap 18 to the lower side of the convex plate 17. The fixed pressing plate 19 is adjusted to approach the convex plate 17 from below. The fixed pressing plate 19 and the furnace cover 2 cooperate to clamp on the convex plate 17, completing the installation of the furnace cover 2 and the furnace body 1.

The fixed pressing plate 19 is driven to lift under the driving of the threaded rod 23 and the guiding action of the guide rod 24. The fixed pressing plate 19 approaches the convex plate 17 from below. The fixed pressing plate 19 and the furnace cover 2 clamp on the convex plate 17 from both sides, realizing the installation of the furnace cover 2 and the furnace body 1.

[0032] Specifically, referring to Figure 1 , in this embodiment, a quartz sand melting device further includes a support frame 26. A rotating motor 27 is provided on the support frame 26.

[0033] Specifically, referring to Figure 1 and Figure 8 , in this embodiment, lifting rings 30 are provided on both the storage bin 3 and the furnace cover 2. The positions of the storage bin 3 or the furnace cover 2 relative to the furnace body 1 are controlled by hanging them on the lifting rings 30 with a hook. When the storage bin 3 is moved above the furnace body 1, feeding of the quartz sand is achieved. When the furnace cover 2 is moved above the furnace body 1, the installation of the furnace cover 2 and the furnace body 1 is completed.

[0034] The working principle of a quartz sand melting device provided in this embodiment is as follows: (1) Under the action of the hook, the storage bin 3 filled with quartz sand is moved above the furnace body 1. The discharge valve of the storage bin 3 is opened, and the moving motor 9 is started. The moving motor 9 drives the moving lead screw 10 to rotate. Under the drive of the moving lead screw 10 and the guiding action of the moving slide bar 11, the feeding box 4 is driven to reciprocate; When the feeding box 4 moves to the right, the driving gear 16 is driven to rotate clockwise through the engagement of the driving gear 16 and the rack 6. The driving gear 16 drives the driving gear 14 to rotate counterclockwise, thereby driving the conveyor belt 7 to rotate counterclockwise.

In the initial state, the fixed pressing plate 19 corresponds to the through gap 18. When the furnace cover 2 is placed on the furnace body 1, the fixed pressing plate 19 passes through the intermittent through hole. Then, the furnace cover 2 is rotated to adjust the fixed pressing plate 19 below the convex plate 17. (3) Start the fixed motor 20 to rotate forward. Driven by the drive chain 25, the fixed motor 20 drives the nut cylinder 22 to rotate. The nut cylinder 22 drives the threaded rod 23 to rise. The threaded rod 23 and the guide rod 24 cooperate to drive the fixed pressing plate 19 to move upward.
