Description

Technical Field

[0001] The invention relates to the technical field of glass manufacturing, and in particular to a fully enclosed isolated island type glass melting furnace feeding device. Background Art

[0002] Float glass raw materials need to be melted into molten glass in a high-temperature melting furnace, which is also the key energy consumption in float glass production; In the float glass production process, the material thrown out by the blanket feeder currently used is spread like a carpet. The entire raw material melting area inside the melting furnace is evenly covered with a layer of raw material. The heated area of ​​the material layer is almost the area of ​​the melting zone of the melting furnace. This heat transfer area is almost at the lowest value of this system. Moreover, when the surface layer of the raw material is melted, the molten glass liquid covers the unmelted raw material like a quilt. Both the glass raw material and the glass liquid are poor conductors of heat, which causes the temperature difference between the heating flame at the top of the melting furnace and the melted glass liquid below to decrease, the heat transfer rate is reduced, and the covered glass raw material is difficult to melt. At the same time, the molten glass liquid will reflect the radiant heat back, which increases the temperature of the furnace arch and aggravates the burning of the arch bricks. The heat absorption of the glass raw material is reduced, resulting in a decrease in the melting rate and an increase in heat consumption. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] Example 1: Reference Figure 1-Figure 7 A fully enclosed isolated glass melting furnace charging device includes glass raw materials, a tank kiln 1 for melting the glass raw materials at high temperature to form a glass solution 10 and accommodating the glass solution 10, a charging pool 101 is provided below the tank kiln 1, the charging pool 101 is communicated with the inside of the tank kiln 1, a charging port 11 is provided at the top left side of the charging pool 101, a high-temperature heating part 102 is provided in the middle of the inner wall of the tank kiln 1, and a charging structure is provided above the charging port 11; The feeding structure includes a raw material bin 4, which is fixedly installed above the feeding port 11, and a fixing frame 5 is installed between the side wall of the raw material bin 4 and the side wall of the pool kiln 1, and the raw material bin 4 is fixedly connected to the side wall of the pool kiln 1 through the fixing frame 5, and the output end of the raw material bin 4 corresponds to the feeding port 11, and a split-type pneumatic valve 7 is installed at the output end of the raw material bin 4, and a raw material push rod 6 is installed on the left side of the inner wall of the feeding pool 101; When in use, the split pneumatic valve 7 is opened, the raw material push rod 6 is in the initial position, and the glass raw materials naturally fall into the feeding pool 101 under the action of their own gravity to form an island-type material pile 18. When the height of the pile reaches the feeding port 11, the bottom end of the feeding port 11 will be blocked, and the feeding will stop naturally. At this time, the split pneumatic valve 7 is closed to stop feeding, and the raw material push rod 6 is started to move horizontally toward the inside of the tank kiln 1; the island-type material pile 18 is pushed into the tank kiln 1, and the raw material push rod 6 returns to the initial position, as shown in FIG. Figure 2 In the position shown, the split pneumatic valve 7 is opened to continue the feeding cycle; It should be noted that, when the raw material push rod 6 moves horizontally toward the inside of the tank kiln 1, the raw materials retained in the feeding port 11 will be pushed into the tank kiln 1 along with the isolated material pile 18 and fall to the left side of the push plate 601 of the raw material push rod 6, and a thin material layer will be formed on the top of the glass liquid in the feeding pool 101 on this side. This material layer can effectively shield the high-temperature radiation of the glass liquid from the influence on the raw material push rod 6 and the split-type pneumatic valve 7, thereby reducing the influence of high temperature on the raw material push rod 6 and the split-type pneumatic valve 7 and shortening the service life; In the above technical solution, in order to prevent the glass raw materials from spreading flat, during the melting process of the glass raw materials, the glass raw materials on the top surface melt and wrap the unmelted glass raw materials in the lower layer, and the gas generated when the inner material melts cannot be discharged, causing the melting gas explosion phenomenon. Therefore, based on this problem, a feeding structure for stacking the glass raw materials into an isolated island-type material pile 18 is provided on the feeding port 11. By stacking them into an isolated island-type material pile 18, once the raw materials on the isolated island-type material pile 18 are melted into glass liquid, they will immediately flow to the bottom of the isolated island-type material pile 18, exposing the unmelted raw materials and continuing to melt. When an island-type material pile 18 floats on the glass liquid, about half of its volume sinks into the molten glass liquid. When the raw materials on the top of the island-type material pile 18 melt and flow down to the bottom of the island-type material pile 18, the unmelted raw materials submerged under the glass liquid surface will rise and emerge from the glass liquid surface due to buoyancy, and continue to maintain the shape of an island. This process will continue until the entire island-type material pile 18 is completely melted. The entire melting process is maintained at a maximum heat exchange area and a maximum temperature difference, thereby improving the overall raw material melting efficiency and improving energy utilization. Further optimized is that a signal sensor 16 and a signal receiver 17 are respectively installed on the left side of the push plate 601 of the raw material push rod 6 and the top left side of the inner wall of the feeding pool 101. The signal receiver 17 installed on the feeding pool 101 is located above the push plate 601 when the raw material push rod 6 is in the initial position. The signal sensor 16 and the signal receiver 17 correspond to each other at this time. When the raw material push rod 6 drives the push plate 601 and the signal sensor 16 at the top of the push plate 601 to move, a signal will be triggered. According to the signal feedback, the split pneumatic valve 7 at the output end of the raw material bin 4 is controlled to close and the feeding is stopped. When the material pushing step is finished, the material pushing rod 6 is reset to drive the signal sensor 16 to correspond with the signal receiver 17, and then a signal feedback is sent again to control the split pneumatic valve 7 to open and continue feeding; Such a technical solution is adopted, considering that the opening and closing of the split pneumatic valve 7 is controlled according to the state of the raw material push rod 6, which is in line with the automatic feeding steps and is convenient for control and program setting; Further optimized, the split pneumatic valve 7, the signal sensor 16, and the signal receiver 17 are all electrically connected to the control box 15, and the split pneumatic valve 7 is controlled according to the signal feedback of the signal sensor 16 and the signal receiver 17, so as to simplify the operation steps and improve the efficiency of automatic feeding; It is further supplemented that: the raw material pushing rod 6 also includes a push rod 602 fixedly connected to the left end of the push plate 601, the outer wall of the push rod 602 is slidably connected to the inside of the side wall of the feeding pool 101, the left end of the push rod 602 is fixedly connected to the cross plate 603, and the top of the cross plate 603 is fixedly installed with a connecting rod 605. Both sides of the top of the outer wall of the feeding pool 101 are fixedly connected with a hydraulic cylinder 606, and the output end of the hydraulic cylinder 606 is used for fixed connection with the inner side of the top of the connecting rod 605, and the hydraulic cylinder 606 is controlled to drive the push plate 601 to move through the connecting rod 605, the cross plate 603, and the push rod 602, so as to push the isolated island type material pile 18 to feed the material; Both sides of the horizontal plate 603 are provided with sliding holes, in which a guide rod 604 is slidably connected, and the right end of the guide rod 604 is fixedly connected to the left side of the outer wall of the feeding tank 101; In a specific embodiment, Figure 4 As shown, the push rod 602 and the push plate 601 are both triangular; In a specific embodiment, Figure 5 As shown, in order to make the size of each isolated island material pile 18 similar, a quantitative bin 401 is set below the inner wall of the raw material bin 4, the top of the quantitative bin 401 is communicated with the upper part of the interior of the raw material bin 4, and a bin gate 8 is installed at the top opening of the quantitative bin 401. The quantitative bin 401 is made into a closed space by the bin gate 8 and the split-type pneumatic valve 7. Since the volume of the closed space is fixed, the volume of the glass raw material exported each time by opening the split-type pneumatic valve 7 is equal, so that the size of each isolated island material pile 18 is similar; The silo gate plate 8 in the above scheme is supplemented, such as Figure 5-Figure 6As shown, the silo gate 8 also includes a rectangular frame 802, which is fixedly installed on the top of the outer wall of the quantitative bin 401. Slide grooves 803 are provided on both sides of the inner wall of the rectangular frame 802, and the left side is opened as an open structure. The inner wall of the opening structure is slidably connected with a sealing plate 801, and the top of the quantitative bin 401 is sealed by the sealing plate 801. One end of the sealing plate 801 extends into the rectangular frame 802 and is slidably connected to the inner wall of the slide groove 803. When the sealing plate 801 moves along the inner wall of the slide groove 803, the movement of the sealing plate 801 is guided. L-shaped connecting rods 804 are fixedly connected to both sides of the left end of the sealing plate 801, and mounting brackets 805 are fixedly connected to both sides of the rectangular frame 802. Hydraulic cylinder 806 is fixedly installed on the inner side of the mounting bracket 805, and the output end of the hydraulic cylinder 806 is fixedly connected to one end of the L-shaped connecting rod 804.

[0019] In a specific embodiment, the lower part of the raw material bin 4 is set to be conical, with the width at the top decreasing from the top to the narrowness at the bottom, so as to facilitate the gathering of discharged materials for stacking; It is further supplemented that: since the glass raw materials are all granular materials and powdery materials, in order to avoid the accumulation of materials in the conical raw material bin 4 blocking the transmission channel at the bottom, the materials are not guided into the quantitative bin 401, and a stirring rod 402 is installed in the raw material bin 4, and the top of the stirring rod 402 is connected to a driving motor 1 403, and the driving motor 1 403 is fixedly installed on a motor bracket 410 fixedly connected to the middle part of the top of the raw material bin 4, such as Figure 7 As shown, by controlling the driving motor 403 to drive the stirring rod 402 to rotate, the materials in the raw material bin 4 are broken up to avoid the accumulation of materials and the inability to guide the materials.

[0020] Example 2: Reference Figure 7 On the basis of Example 1, considering that the stirring rod 402 only rotates in the middle of the raw material bin 4 during stirring, the material in the raw material bin 4 is broken up, and a part of the material near the side is affected by the material extrusion and adheres to the inner wall of the raw material bin 4. In this case, the material adhered to the inside of the raw material bin 4 cannot be peeled off or exported, which brings many inconveniences. Therefore, based on this problem, an outer frame 404 is installed on the outer wall of the rotating shaft of the stirring rod 402, and a scraper 405 is installed on the outer side of the outer frame 404. The end of the scraper 405 away from the outer frame 404 contacts the inner wall of the raw material bin 4. When the driving motor 403 drives the stirring rod 402 to rotate, it also drives the outer frame 404 and the scraper 405 to rotate, and the materials inside and outside the raw material bin 4 are broken up by the outer frame 404. At the same time, the material adhered to the inner wall of the raw material bin 4 is scraped off by the scraper 405 to avoid affecting the use efficiency due to the inability to remove the adhesion.

[0021] Example 3: Reference Figure 8On the basis of the second embodiment, considering that when the stirring rod 402, the outer frame 404 and the scraper 405 are controlled to rotate to break up the materials, since the stirring rod 402 and the outer frame 404 have the same rotation direction, the agglomerated materials may be pushed away by the stirring rod 402 and the outer frame 404 without being broken up, and the subsequent falling into the quantitative bin 401 may cause the quantitative bin 401 to be blocked, affecting the subsequent stacking efficiency and bringing many inconveniences. Therefore, based on this problem, the difference from the second embodiment is that the rotation axis of the outer frame 404 and the stirring rod 402 is The connection relationship between them is different, the outer frame 404 is rotatably connected to the outer wall of the rotating shaft of the stirring rod 402 through a bearing, and a sleeve 406 is installed in the middle of the top of the outer frame 404, the inner side of the sleeve 406 is rotatably connected to the outer wall of the rotating shaft of the stirring rod 402, and is coaxial and concentric with the rotating shaft, and a gear linkage structure is installed on the outer wall of the sleeve 406, so that when the stirring rod 402 rotates, the sleeve 406 and the outer frame 404 connected to the sleeve 406 are driven to rotate in the opposite direction through the gear linkage structure, and the agglomerated materials are dispersed by the misalignment between the outer frame 404 and the stirring rod 402; The gear linkage structure includes: two bevel gears 1 407 and one bevel gear 2 408, the tooth ends of the two bevel gears 1 407 are arranged opposite to each other, the two bevel gears 1 407 are respectively fixedly mounted on the top of the outer wall of the sleeve 406 and above the outer wall of the rotating shaft of the stirring rod 402, a bevel gear 2 408 is provided on one side of the opposite end of the two bevel gears 1 407, the top and bottom ends of the bevel gear 2 408 are respectively meshed with the two bevel gears 1 407, a support plate 409 is rotatably connected to the left side of the bevel gear 2 408, the bottom end of the support plate 409 is fixedly connected to the top of the raw material bin 4, when the stirring rod 402 rotates, the bevel gear 1 407 fixedly mounted on the stirring rod 402 drives the bevel gear 2 408 to rotate, and the bevel gear 2 408 drives the bevel gear 1 407 at the top of the outer wall of the sleeve 406 to rotate, and through the meshing characteristics between the two groups of bevel gears 1 407 and the group of bevel gears 2 408, the sleeve 406 is driven to rotate in the opposite direction to the rotation direction of the stirring rod 402; There are also two other equivalent alternative gear linkage structures to drive the sleeve 406 to rotate in the opposite direction to the stirring rod 402; First, a driving motor 2 fixedly installed on one side of the raw material bin 4 can be used, and a synchronous wheel is installed at the output end of the driving motor 2 and the outer wall of the top end of the sleeve 406. The two synchronous wheels are connected by a synchronous belt. By controlling the rotation direction of the driving motor 2 to be opposite to the rotation direction of the driving motor 1 403, the sleeve 406 is driven to rotate in the opposite direction of the stirring rod 402 through the transmission between the synchronous belt and the synchronous wheel; Second, a driving motor 2 can be added and fixedly installed on one side of the raw material bin 4. A gear 4 is installed at the output end of the driving motor 2 and the top outer wall of the sleeve 406. The two gears 4 are meshed with each other. The rotation direction of the driving motor 2 is the same as that of the driving motor 1 403. The sleeve 406 is driven to rotate by utilizing the characteristic that the two gears 4 are meshed with each other and rotate in opposite directions.
