Abstract
Description
Technical Field
[0001] The invention relates to the technical field of annealing devices, and in particular to an energy-saving annealing device for float glass and an annealing process thereof. Background Art
[0002] The preparation of float glass includes raw material melting preparation, float forming, cooling annealing, cutting and forming and other processes. Among them, the float glass surface temperature is lowered during annealing to eliminate the internal stress of the glass and improve the physical properties of the glass. During the cooling and annealing process of the glass, if the thickness of the glass supported by the float forming is thin during the preparation of the glass, then after entering the annealing device, the glass may be broken under the action of the internal stress of the glass. If these fragments are not handled in time, they may affect the subsequent glass annealing.
[0003] In order to deal with these fragments in time, the existing float glass annealing device is provided with a push plate under the roller conveyor. The glass fragments fall into the storage chamber through the gap between the rollers of the roller conveyor, and then the push plate is moved to make the fragments in the storage chamber move closer to the discharge port. The operator can collect the fragments at the discharge port to realize the timely cleaning of the glass fragments in the annealing device.
[0004] Although this can complete the cleaning of glass debris out of the annealing device, the following problem still exists: the push plate returns directly to its original position after transporting the glass debris. If there is still glass debris on the top at this time and it falls into the lower collection area, or if part of the original glass debris is not brought to the discharge port by the push plate, the push plate may return with the debris on its way back. As a result, even if the push plate performs the cleaning work again, the returned debris will still be pushed to the other end, causing the clean debris to gather at the other end of the discharge port and be difficult to clean.

DETAILED DESCRIPTION
[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] like Figure 2 to Figure 8 As shown, this embodiment provides an energy-saving annealing device for float glass, the structure of which includes a fixing frame 9.
[0038] The shell 1 in this embodiment is fixedly arranged on the fixing frame 9, the heat preservation chamber 13, the partition chamber 15 and the cooling chamber 14 are arranged in the shell 1, the first heater 131 is fixedly arranged on the top of the heat preservation chamber 13, the second heater 141 is arranged in the cooling chamber 14, and the feed port 11 and the discharge port 12 are arranged on both sides of the shell 1. The roller conveyor 4 is arranged in the shell 1 to ensure that the broken float glass can fall through the gap between the rollers of the roller conveyor 4 under the premise of ensuring the transportation of float glass. The roller conveyor 4 passes through the heat preservation chamber 13, the partition chamber 15 and the cooling chamber 14 at the same time, and the collection box 2 is arranged at the bottom of the roller conveyor 4 to collect glass slag. The collection chamber 21 is arranged in the collection box 2, the discharge port 22 is arranged at the end of the collection chamber 21 close to the discharge port 12, and a plurality of cleaning parts 8 are arranged in the collection chamber 21.

In this embodiment, the housing 1 is divided into a heat preservation chamber 13, a partition chamber 15 and a cooling chamber 14, so that the heat preservation chamber 13 and the cooling chamber 14 have different temperatures, and a partition chamber 15 is arranged between the heat preservation chamber 13 and the cooling chamber 14 to reduce the transition temperature, so that after the float glass passes through the partition chamber 15 and the cooling chamber 14 from the heat preservation chamber 13, the surface temperature of the glass gradually decreases, the stress of the glass is gradually released, and the unqualified rate of the glass is reduced.
[0039] The heat preservation chamber 13, the partition chamber 15 and the cooling chamber 14 in this embodiment are all rectangular parallelepiped structures, and the two ends of the partition chamber 15 are connected to the heat preservation chamber 13 and the cooling chamber 14 respectively, and the horizontal height of the partition chamber 15 is lower than the horizontal height of the heat preservation chamber 13 and the horizontal height of the cooling chamber 14. The height reduction of the partition chamber 15 in this embodiment reduces the air flow rate of the heat preservation chamber 13 entering the cooling chamber 14, so that the temperature difference between the heat preservation chamber 13 and the cooling chamber 14 is achieved, and the float glass can be stably cooled and annealed, thereby improving the qualified rate of the float glass.
[0040] The transport structure in this embodiment includes a first conveyor belt 51 and a second conveyor belt 52 arranged on the inner walls of both sides of the collection chamber 21, which are used to control the movement of the cleaning member 8 from both sides at the same time, so that the movement of the cleaning member 8 is more stable and not easy to deviate. The connecting shaft 511 is fixedly arranged between the first conveyor belt 51 and the second conveyor belt 52, and is used to synchronize the movement of the first conveyor belt 51 and the second conveyor belt 52. The first connecting member 61 is fixedly arranged on the first conveyor belt 51, the second connecting member 62 is fixedly arranged on the second conveyor belt 52, the connecting rod 7 is rotatably arranged between the first connecting member 61 and the second connecting member 62, and the cleaning member 8 is detachably connected to the connecting rod 7. In this embodiment, the cleaning member 8 is driven to move by the first conveyor belt 51 and the second conveyor belt 52, so that the cleaning member 8 abuts against the bottom of the collection chamber 21 when moving toward the discharge port 22, ensuring the cleaning of the glass fragments; the cleaning member 8 can be separated from the bottom of the collection chamber 21 when moving away from the discharge port 22, ensuring that the glass fragments will not be brought back, thereby improving the cleaning efficiency.
[0041] In this embodiment, the top of the feed port 11, the discharge port 12, between the heat preservation chamber 13 and the partition chamber 15, and between the partition chamber 15 and the cooling chamber 14 are all fixed with heat insulation curtains 111 to reduce the loss of heat inside the shell 1, making the annealing device more energy-saving and environmentally friendly. The first installation box 31 and the second installation box 32 are fixedly arranged on both sides of the collection chamber 21, and the first installation box 31 and the second installation box 32 are both connected to the collection chamber 21. The first conveyor belt 51 is arranged in the first installation box 31, and the second conveyor belt 52 is arranged in the second installation box 32. The first box cover 311 and the second box cover 321 are respectively arranged on the first installation box 31 and the second installation box 32, and the first box cover 311 is fixed to the first installation box 31 by bolts, and the second box cover 321 is fixed to the second installation box 32 by bolts. The design of the first box cover 311 and the second box cover 321 in this embodiment ensures that when the first conveyor belt 51 and the second conveyor belt 52 are damaged, the first conveyor belt 51 and the second conveyor belt 52 can be replaced immediately.
[0042] The sealing door 221 in this embodiment is rotatably arranged on the discharge port 22 to seal the entire housing 1 to prevent heat loss during normal annealing operation. The first partition plate 312 is arranged between the first installation box 31 and the collection chamber 21, and the first partition plate 312 is fixedly connected to the bottom of the first installation box 31. The second partition plate 322 is arranged between the second installation box 32 and the collection chamber 21, and the second partition plate 322 is fixedly connected to the bottom of the second installation box 32. The design of the first partition plate 312 and the second partition plate 322 in this embodiment ensures that the glass fragments will not fall into the first installation box 31 or the second installation box 32 when driven by the cleaning member 8, causing inconvenience to the cleaning of the glass fragments.
[0043] The rotation hole 612 in this embodiment is arranged on the first limiting member 6111, the connecting rod 7 passes through the rotation hole 612 and is rotationally connected in the rotation hole 612, the first limiting bolt 71 is fixedly arranged at the end of the connecting rod 7, the limiting spring 72 is sleeved on the connecting rod 7, one end of the limiting spring 72 is fixedly connected to the first limiting member 6111, and the other end of the limiting spring 72 is fixedly connected to the first limiting bolt 71. Such a design enables the cleaning member 8 to rotate toward the bottom of the collecting chamber 21 due to the action of the limiting spring 72 when the cleaning member 8 moves toward the discharge port 22, so as to ensure that the cleaning member 8 is fully in contact with the bottom of the collecting chamber 21 and that the glass fragments can be taken away from the collecting chamber 21.
[0044] In this embodiment, the first mounting groove 611 is arranged on the side of the first limiting member 6111 away from the first limiting bolt 71. The first mounting groove 611 is a cylindrical structure. A rotating hole 612 is arranged in the center of the first mounting groove 611. The first limiting member 6111 is fixedly arranged on the side wall of the first mounting groove 611. The second limiting member 76 is fixedly arranged on the connecting rod 7. The second limiting member 76 is arranged in the first mounting groove 611 and is rotatably connected to the first mounting groove 611. The second limiting bolt 73 is arranged on the connecting rod 7 through a threaded connection. The projection surface of the second limiting bolt 73 along the central axis direction of the connecting rod 7 falls within the projection surface of the first mounting groove 611 along the central axis direction of the connecting rod 7. The second limiting rod abuts against the first limiting member 6111, and the second connecting member 62 has the same structure as the first connecting member 61. This design ensures that when the cleaning piece 8 is driven by the first conveyor belt 51 and the second conveyor belt 52 to move away from the discharge port 22, the cleaning piece 8 will not rotate excessively due to the action of the limit spring 72, and the cleaning piece 8 is approximately perpendicular to the belt surface of the first conveyor belt 51, so that when the cleaning piece 8 begins to abut against the bottom of the collection chamber 21, it can rotate under the movement of the first conveyor belt 51 and the second conveyor belt 52, and the cleaning piece 8 will not be deformed.
[0045] The cleaning member 8 in this embodiment is made of a high temperature resistant material to prevent the cleaning member 8 from being melted in the annealing device. The cleaning member 8 is a rectangular parallelepiped structure, and a collection groove 81 is provided on the cleaning member 8, and the collection groove 81 is a "V"-shaped structure. The design of the collection groove 81 makes the glass fragments concentrate toward the center of the collection groove 81 during the movement, and the glass fragments are not easy to move to the sides and separate from the cleaning member 8. The cleaning member 8 in this embodiment is preferably made of ceramic material.
[0046] In this embodiment, the second mounting groove 75 is arranged on the connecting rod 7, the cleaning member 8 is plugged into the second mounting groove 75, a plurality of first locking bolts 74 are arranged on the side wall of the second mounting groove 75 by threads, the first locking bolts 74 are in contact with the cleaning member 8, the first connecting member 61 is provided with a second locking bolt 63 and a third locking bolt 64, the first connecting member 61 is connected and fixed to the first conveyor belt 51 by the second locking bolt 63 and the third locking bolt 64, the plane where the central axis of the second locking bolt 63 and the central axis of the third locking bolt 64 are located is perpendicular to the movement direction of the cleaning member 8. Such a design ensures that the cleaning member 8 is detachably connected to the connecting rod 7, so that when the cleaning member 8 is damaged, the cleaning member 8 can be disassembled, installed and replaced.
[0047] Another object of the present invention is to provide an energy-saving annealing process for float glass.
[0048] S1: First start the first heater 131 in the heat preservation chamber 13 and the second heater 141 in the cooling chamber 14 to preheat the heat preservation chamber 13 and the cooling chamber 14, so that the temperature in the heat preservation chamber 13 reaches 580° and the temperature in the cooling chamber 14 reaches 520°; the temperature of the heat preservation chamber 13 in this embodiment is the surface temperature of the float glass after melting and forming, which is about 580° after measurement. The temperature of the cooling chamber 14 in this embodiment is 520°. When the temperature of the float glass drops from 580° to 520°, the internal stress of the glass will be relatively large. Such a design ensures that the stress of the float glass in the annealing device is fully released.
[0049] S2: The prepared float glass is placed on the roller conveyor 4 from the feed port 11, and the float glass passes through the heat preservation chamber 13, the partition chamber 15 and the cooling chamber 14 in sequence through the roller conveyor 4 to achieve the cooling annealing of the float glass. Through the setting of the heat preservation chamber 13, the partition chamber 15 and the cooling chamber 14, the external environment of the float glass is slowly cooled from high to low under the drive of the roller conveyor 4, thereby improving the qualified rate of the cooling annealing of the float glass.
[0050] S3: When some unqualified float glass passes through the cooling chamber 14, the ambient temperature drops, causing the float glass to break, and the glass fragments fall into the collecting chamber 21 through the gaps on the roller conveyor 4;
[0051] S4: Start the first conveyor belt 51, so that the first conveyor belt 51 drives the cleaning member 8 to contact the bottom of the collection chamber 21 and move toward the discharge port 12, and the glass fragments are driven by the cleaning member 8 to move toward the discharge port 22. Such a design ensures that the glass fragments move and gather toward the discharge port 22, which helps to better clean the glass fragments.
[0052] The working process of this embodiment is as follows: float glass enters the roller conveyor 4 through the feed port 11. When entering the heat preservation chamber 13, the internal stress of the glass is released less because the temperature difference between the heat preservation chamber 13 and the surface of the float glass is small, and the glass will not break or crack; when the float glass enters the cooling chamber 14 through the separation chamber 15, some glass of substandard quality breaks or shatters due to the temperature drop, and the broken glass fragments fall into the collecting chamber 21 from the gap between the rollers of the roller conveyor 4. At this time, the first conveyor belt 51 is started, and the first conveyor belt 51 drives the second conveyor belt 52 to move. When the cleaning member 8 moves toward the discharge port 22, the first connecting member 61 on the first conveyor belt 51 and the second connecting member 62 on the second conveyor belt 52 drive the cleaning member 8 to abut against the bottom of the collecting chamber 21, and move toward the discharge port 22 with the debris; when the cleaning member 8 moves away from the discharge port 22, because the first connecting member 61 is brought above the first conveyor belt 51, the cleaning member 8 is separated from the bottom of the collecting chamber 21 and moves away from the discharge port 22.
[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
