[0001] The present invention relates to the technical field of cover glass raw material storage, and particularly to a cooling device for a bin in front of a cover glass furnace. Background Art

[0002] During the production of cover glass, the ambient temperature where the bin in front of the furnace is located is high. In a high-temperature environment, the raw materials in the bin will agglomerate and block the material, and the raw materials cannot be smoothly fed into the furnace, which will cause production interruption.

However, this design is difficult to ensure the uniformity of raw material cooling inside the bin. Both temperature rise and humidity increase will cause raw material agglomeration. Therefore, relying solely on cooling measures is difficult to effectively prevent agglomeration.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the drawings.

[0018] Embodiment: Please refer to Figures 1-8 , a cooling device for the pre-furnace silo of a cover glass furnace, including a silo 1, a feeding hopper 7 is installed at the top of the silo 1, and a discharge port 8 with a funnel-shaped structure is opened at the bottom of the silo 1. Raw materials are supplemented into the silo 1 through the feeding hopper 7, and the raw materials are discharged through the discharge port 8.

[0019] It further includes: Partition 2, there are multiple of them, and the multiple partitions 2 are arranged in sequence along the height direction of the silo 1. A cooling pipeline 3 is installed inside the partition 2. Both ends of the cooling pipeline 3 penetrate through the silo 1 and are rotationally connected to the silo 1. There is a damping structure between the cooling pipeline 3 and the outer wall of the silo 1, so that the cooling pipeline 3 will not rotate without being driven by the external force of two gears. Both ends of the cooling pipeline 3 respectively extend to the outside of the first structure box 6 and the second structure box 9, and are both rotationally connected with a rotary seal joint 29. The two rotary seal joints 29 are respectively installed on the outer walls of the first structure box 6 and the second structure box 9. One of the rotary seal joints 29 is connected to a water supply device, and the other rotary seal joint 29 is connected to a water storage tank. The setting of the rotary seal joint 29 enables the cooling pipeline 3 to rotate normally during use; The silo 1 stores granular raw materials. The granular raw materials are stored in different areas through the partition 2 to prevent the raw materials that enter the silo 1 first and the raw materials that enter later from being affected by each other due to large temperature differences. Coolant is introduced into the cooling pipeline 3 inside the partition 2 through a water supply device, and then the raw materials in the top area thereof are cooled through the partition 2.

[0020] The temperature equalizing and anti-caking mechanism is provided with multiple groups. The temperature equalizing and anti-caking mechanism is located above the partition plate 2. The temperature equalizing and anti-caking mechanism includes a driven disk 4 rotatably connected to the outer wall of one side of the bin 1, a plurality of mixing rods 5 slidably connected inside the driven disk 4, a driving component for driving the driven disk 4 to rotate, and a displacement component for driving the plurality of mixing rods 5 to move. A second structure box 9 is installed on the outer wall of one side of the bin 1; the displacement component includes a first lead screw 10 rotatably connected inside the second structure box 9, a first motor 11 installed on the outer wall of the second structure box 9, and a driving disk 12 fixedly connected to one end of the plurality of mixing rods 5. An active block 13 is threadedly connected to the outside of the first lead screw 10. The driving disk 12 is rotatably connected to the outer wall of the active block 13; the output end of the first motor 11 is fixedly connected to one end of the first lead screw 10; a guide rod 14 is fixedly connected inside the second structure box 9. The active block 13 is slidably sleeved on the outside of the guide rod 14. The driving component includes a second motor 15 installed on the outer wall of the second structure box 9 and a linkage sleeve 16 slidably sleeved on the outside of the output shaft of the second motor 15. A key pin is fixedly connected to the outside of the output shaft of the second motor 15. A key groove is formed inside the linkage sleeve 16. The key pin is slidably connected inside the key groove; the driving disk 12 is fixedly sleeved on the outside of the linkage sleeve 16. A through groove is formed through the inside of the active block 13. The inner diameter of the through groove is larger than the outer diameter of the linkage sleeve 16; During the raw material storage process, the mixing rods 5 are located inside the bin 1 and above the partition plate 2. By controlling the second motor 15 to drive the linkage sleeve 16 and the driving disk 12 on the outside of its output shaft to rotate, the plurality of mixing rods 5 are driven to rotate synchronously in the circumferential direction, turning the raw materials on the top of the partition plate 2, enabling the raw materials at different positions to cyclically contact the partition plate 2, and breaking up the lumps in the raw materials; When it is necessary to guide the raw materials on the top of the partition plate 2 downward, by controlling the first motor 11 to drive the first lead screw 10 to rotate counterclockwise, the active block 13 is driven to move to the right along the outside of the guide rod 14, and the driving disk 12 moves to the right synchronously, thereby driving the plurality of mixing rods 5 to move to the right along the inside of the driven disk 4 until the left end of the mixing rod 5 is aligned with the left outer wall of the driven disk 4. During this process, the raw materials adhered to the outside of the mixing rods 5 are removed, and at the same time, space is vacated for the partition plate 2 to be flipped. After the guiding is completed and the partition plate 2 returns to the horizontal state, by controlling the first motor 11 to drive the first lead screw 10 to rotate clockwise, the active block 13 is driven to move to the left along the outside of the guide rod 14, and the driving disk 12 moves to the left synchronously, thereby driving the plurality of mixing rods 5 to move into the bin 1 and driving the plurality of mixing rods 5 to rotate in the circumferential direction again to turn the raw materials on the top of the partition plate 2.

[0021] The first structure box 6 is installed on the outer wall of the other side of the bin 1; The material guiding mechanism is arranged inside the first structural box 6 and is used to drive each partition plate 2 to rotate successively from bottom to top. The material guiding mechanism includes a first gear 17 installed outside the cooling pipeline 3, a second lead screw 18 rotatably connected inside the first structural box 6, and a third motor 19 installed on the top of the first structural box 6; the output end of the third motor 19 is fixedly connected to the top end of the second lead screw 18; a first rack 20 is threadedly connected to the outside of the second lead screw 18. When the first rack 20 moves upward, it meshes with each first gear 17 in turn. The first gear 17 is a one-way gear, and the first rack 20 is slidably engaged with the outer wall of the bin 1; When it is necessary to discharge materials from the inside of the bin 1, it is necessary to guide the raw materials in each area inside the bin 1 downward in turn. By controlling the third motor 19 to drive the second lead screw 18 to rotate counterclockwise, the first rack 20 is driven to move upward along the outer wall of the bin 1. When the first rack 20 meshes with the lowermost first gear 17, the cooling pipeline 3 is driven to rotate, and the partition plate 2 is synchronously driven to rotate, and the raw materials on the top of the partition plate 2 are gradually discharged downward. During the entire meshing process of the first rack 20 and the first gear 17, the cooling pipeline 3 and the partition plate 2 are driven to rotate 180°, so that the raw materials on the top of the partition plate 2 can be fully discharged. As the first rack 20 continues to move upward, each partition plate 2 is driven to flip 180° in turn, so that the raw materials on the top of each partition plate 2 are discharged downward in turn until the first rack 20 completely loses meshing with the uppermost first gear 17; After the raw materials on the top of the partition plate 2 are guided and delivered, control the third motor 19 to drive the second lead screw 18 to rotate clockwise, drive the first rack 20 to move downward. The first rack 20 also meshes with each first gear 17 in turn. However, since the first gear 17 is a one-way gear, the first rack 20 moving upward drives the first gear 17 to rotate counterclockwise, and the cooling pipeline 3 rotates accordingly. The first rack 20 moving downward drives the first gear 17 to rotate clockwise, and the cooling pipeline 3 does not rotate accordingly, and it is ensured that the first rack 20 loses meshing with the lowermost first gear 17.

[0022] The auxiliary processing mechanism is arranged inside the first structural box 6 and is used to drive each partition plate 2 to reciprocally rotate within a set angle. The auxiliary processing mechanism includes a fourth motor 21 installed on the top of the first structural box 6, a reciprocating screw 22 fixedly sleeved outside the output shaft of the fourth motor 21, and a second gear 23 fixedly sleeved outside the cooling pipeline 3; a linkage frame 24 is threadedly connected to the outside of the reciprocating screw 22. The linkage frame 24 is slidably engaged with the inner wall of the first structural box 6. A plurality of second racks 25 are fixedly connected to the outer wall of the linkage frame 24 along its height direction, and a plurality of second gears 23 are respectively matched with the plurality of second racks 25; During the process of the mixing rod 5 turning over the raw materials on the top of the partition plate 2, the reciprocating screw 22 outside the output shaft is driven to rotate by the fourth motor 21, driving the linkage frame 24 to reciprocate up and down along the outside of the reciprocating screw 22, and driving a plurality of second racks 25 to reciprocate up and down synchronously through the linkage frame 24. Through the meshing action between the plurality of second racks 25 and the plurality of second gears 23 respectively, the cooling pipeline 3 and the partition plate 2 are driven to rotate reciprocally within a range of plus or minus 20°, so that the raw materials at the end of the partition plate 2 can repeatedly gather towards the middle thereof, enabling the raw materials on the top of the partition plate 2 to evenly contact the partition plate 2, thereby uniformly cooling the raw materials on the top of the partition plate 2. At the same time, the agglomerates in the raw materials on the top of the partition plate 2 can be evenly broken up, avoiding the problem that some agglomerates are difficult to be broken up due to the existence of dead zones at the top of the partition plate 2. Before the raw materials on the top of the partition plate 2 are downwardly conveyed, the second rack 25 is driven to be separated from the second gear 23, so that the partition plate 2 is restored to a horizontal state.

[0023] Extension sealing mechanisms are installed at both ends of the partition plate 2. The extension sealing mechanism includes a chute 26 opened at the end of the partition plate 2, a sealing strip 27 slidably connected inside the chute 26, and a plurality of springs 28 fixedly connected to the inner wall of the chute 26. The other end of the spring 28 is fixedly connected to the outer wall of the sealing strip 27; During the process of the mixing rod 5 turning over the raw materials on the top of the partition plate 2, since the partition plate 2 will rotate reciprocally within a range of plus or minus 20°, a gap will be generated between the partition plate 2 and the inner wall of the silo 1. Through the elastic action of the spring 28, the sealing strip 27 is always in contact with the inner wall of the silo 1, preventing the raw materials from leaking downward during the turning-over process.

[0024] Working principle: The silo 1 stores granular raw materials. The partition 2 divides the granular raw materials into areas for storage, preventing the raw materials that enter the silo 1 first and those that enter later from influencing each other due to large temperature differences. The cooling liquid is introduced into the cooling pipeline 3 inside the partition 2 through the water supply equipment, and then the partition 2 cools the raw materials in its top area. During the storage of the raw materials, the mixing rods 5 are located inside the silo 1 and above the partition 2. By controlling the second motor 15 to drive the linkage sleeve 16 and the driving disc 12 outside its output shaft to rotate, multiple mixing rods 5 are driven to rotate synchronously in the circumferential direction to turn over the raw materials on the top of the partition 2. At the same time, the fourth motor 21 drives the reciprocating screw 22 outside its output shaft to rotate, driving the linkage frame 24 to reciprocate up and down along the outside of the reciprocating screw 22, and driving multiple second racks 25 to reciprocate up and down synchronously through the linkage frame 24. Through the meshing between multiple second racks 25 and multiple second gears 23 respectively, the cooling pipeline 3 and the partition 2 are driven to rotate reciprocally within a range of 20° in both positive and negative directions, so that the raw materials at the end of the partition 2 can repeatedly gather towards the middle, enabling the raw materials on the top of the partition 2 to evenly contact the partition 2, thereby evenly cooling the raw materials on the top of the partition 2, and at the same time, evenly breaking up the lumps in the raw materials on the top of the partition 2, avoiding the problem that some lumps are difficult to break up due to dead zones existing on the top of the partition 2. When it is necessary to guide the raw materials on the top of the partition 2 downward, by controlling the first motor 11 to drive the first lead screw 10 to rotate counterclockwise, the movable block 13 is driven to move to the right along the outside of the guide rod 14, and the driving disc 12 moves to the right synchronously, thereby driving multiple mixing rods 5 to move to the right along the inside of the driven disc 4 until the left end of the mixing rod 5 aligns with the left outer wall of the driven disc 4. During this process, the raw materials adhered to the outside of the mixing rod 5 are removed, and at the same time, space is vacated for the partition 2 to flip. When it is necessary to discharge the materials from inside the silo 1, the raw materials in each area inside the silo 1 need to be guided downward in sequence. By controlling the third motor 19 to drive the second lead screw 18 to rotate counterclockwise, the first rack 20 is driven to move upward along the outer wall of the silo 1. When the first rack 20 meshes with the lowermost first gear 17, the cooling pipeline 3 is driven to rotate, and the partition 2 is synchronously driven to rotate, starting to gradually export the raw materials on the top of the partition 2 downward. During the entire meshing process between the first rack 20 and the first gear 17, the cooling pipeline 3 and the partition 2 are driven to rotate 180°, enabling the raw materials on the top of the partition 2 to be fully discharged. As the first rack 20 continues to move upward, each partition 2 is driven to flip 180° in sequence, enabling the raw materials on the top of each partition 2 to be discharged downward in sequence.
