Description

Technical Field

[0001] The present invention relates to the technical field of glass quenching, and specifically to an air-cooled quenching device for preparing gel network fireproof and heat-insulating glass. Background Art

[0002] Quenching of glass is to uniformly heat the glass products to a temperature close to the softening point temperature (about 620 - 650 °C), and then rapidly and uniformly cool them in a cooling medium (quenching medium) (such as air-cooled quenching, liquid-cooled quenching, etc.).

[0003] However, for thin glass, it has a small heat capacity and a fast heating rate, and is prone to local softening and deformation due to uneven furnace temperature, especially at the end face part of the thin glass.

[0004] For thick glass, the center absorbs heat slowly, and the temperature difference between the surface and the interior can reach 30 - 50 °C, causing thermal stress cracking. Summary of the Invention

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. Some of the thermal rays will first irradiate on the second reflector, then be reflected from the second reflector to the first reflector, and finally irradiate on the edge of the thin glass through the first reflector, thus avoiding the edge of the thin glass from having a fast heat dissipation rate, with a temperature difference between the edge and the middle part reaching 10 - 15 °C, which may cause microcracks at the edge. In addition, it also plays a role in keeping the thermal temperature difference between the edge and the central area of the thin glass within a certain range, avoiding insufficient heat conduction.

[0032] 2. The first reflector and the second reflector will deflect outward with the fixed shaft in the flat seat as the fulcrum, thus enabling the light and heat irradiated by the heating rod to irradiate on the thick glass faster and more fully.

[0033] 3. When the heating rod moves to a position slightly above the conveying roller, most of the irradiated light will be blocked and absorbed by the conveying roller at this time, thus playing a role in preliminarily heating the thick glass during the conveying process.

[0034] 4. When the heating rod moves to a position slightly above the perforating roller, it enables some of the irradiated light to pass through the perforating roller and irradiate on the end face of the thick glass, avoiding the end face from losing temperature.

[0035] 5. When the heating rod is directly above the position between the conveying roller and the perforating roller, it plays a role in heating the stationary thick glass with a greater degree of full - range light irradiation.

[0036] 6. The chimeric ferrule will slide outwards from within the heat insulation ferrule and wrap a part of the surface of the heating rod, thereby progressively reducing the heating treatment of the glass and preventing thermal stress cracking caused by unbalanced internal stress in the glass.

[0037] 7. Since cold air continuously circulates in the air blowing pipe, the pressure inside the air blowing pipe is lower than the pressure inside the quenching tank at this time. Additionally, with the assistance of the aperture, the temperature emitted by the glass will enter the air blowing pipe through the conical hole and the square body hole respectively, thereby achieving the effect of air cooling the glass.

Specific implementation manners

[0052] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features, and it should be known that 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.

[0053] Please refer to Figures 1 to 13 The present invention provides a technical solution: as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, it includes a quenching box 1 for providing a quenching and air-cooling place for special glass. The top of the inner cavity of the quenching box 1 is slidably fitted with a top cover 8. Among them, the quenching box 1 is equipped with a switch door, and a servo motor 2 is fixedly installed on the outside of the quenching box 1;

[0054] An air-cooling mechanism 3 for performing all-round air-cooling treatment on special glass, and the air-cooling mechanism 3 is arranged inside the quenching box 1;

[0055] A first conveying mechanism 4 for conveying and lifting special glass. A first hydraulic cylinder 5 is arranged on the first conveying mechanism 4, and a second conveying mechanism 6 is arranged at the top end of the first hydraulic cylinder 5; among them, the components inside the second conveying mechanism 6 are exactly the same as those inside the first conveying mechanism 4.

[0056] The quenching mechanism 7 for heat treatment of special glass is arranged on the top of the second conveying mechanism 6. When quenching thick glass, the first hydraulic cylinder 5 is started, so that the second conveying mechanism 6 connected to its output end will move upward. At the same time, the quenching mechanism 7 arranged on its top will drive the top cover 8 to move upward together. The top cover 8 will not protrude out of the top of the quenching box 1 and seals the top of the quenching box 1. In addition, the position of the top cover 8 can only be adjusted by the first hydraulic cylinder 5, so as to provide a certain conveying space for the thick glass.

[0057] The air-cooling mechanism 3 includes an electric push plate 31, which is fixedly installed at the bottom of the inner cavity of the quenching box 1. The outside of the output end of the electric push plate 31 is connected with a blowing pipe 32 through a connecting piece. The blowing pipe 32 is used for wrapping the special glass and performing air-cooling treatment;

[0058] The outer end face of the blowing pipe 32 is fixedly installed with an air inlet pipe 33, and one end of the air inlet pipe 33 far from the blowing pipe 32 is connected with an external air-blowing device;

[0059] A conical hole 34 and a square body hole 35 are respectively formed on the inner side of the blowing pipe 32. The square body hole 35 is arranged at the central part of the blowing pipe 32, and the conical holes 34 are symmetrically arranged on both sides of the square body hole 35. After heating is completed, the pneumatic rod 49 is started, so that the sleeve plate 48 connected to its output end will drive the inclined surface table 47 to move towards the center of the quenching box 1. The height of one end of the inclined surface table 47 close to the glass is lower than the height of the glass and is in the shape of an inclined upward slope. Then the inclined surface table 47 will squeeze the bottom of both ends of the glass until the glass is in a suspended state. Then, an external blower is used to blow air into the air inlet pipe 33. The other end of the air inlet pipe 33 is connected to the blowing pipe 32. Immediately afterwards, the electric push plate 31 is started, so that the blowing pipe 32 connected to its output end through a connecting piece will enter the quenching box 1 and respectively surround the glass. A large number of conical holes 34 and square body holes 35 are respectively formed on the inner side of the blowing pipe 32, and the outer inner diameters of the two holes are larger than the inner inner diameters. Because cold air continuously circulates in the blowing pipe 32, the pressure inside the blowing pipe 32 is less than the pressure inside the quenching box 1. In addition, with the addition of the hole diameters, the temperature emitted by the glass will respectively enter the blowing pipe 32 through the conical holes 34 and the square body holes 35, so as to realize the air-cooling and temperature-reducing treatment effect on the glass.

[0060] In addition, the reason for using the square body hole 35 at the center of the blowing pipe 32 and the conical holes 34 on both sides is that the cooling speed at both ends of the glass is relatively fast, while the cooling speed at the center is relatively slow, so as to maintain the equal-speed cooling of the glass.

[0061] Such as Figure 5 、 Figure 6and Figure 7 As shown in Figure 7 , the first conveying mechanism 4 includes a roller table 41, the roller table 41 is fixedly installed at the bottom of the inner cavity of the quenching tank 1, a conveying roller 42 is arranged inside the roller table 41, and both ends of the conveying roller 42 are drivingly connected with a first conveyor belt 43;

[0062] An opening roller 44 is arranged inside the roller table 41, and both ends of the opening roller 44 are drivingly connected with a second conveyor belt 45; By opening the switch door at the right end of the quenching tank 1, then putting the special glass into the quenching tank 1, and then starting the servo motor 2, the opening roller 44 connected to the output end thereof through a coupling will rotate forward. The number of the opening rollers 44 and the conveying rollers 42 are three respectively, and they are alternately arranged on the roller table 41. The opening rollers 44 and the conveying rollers 42 at both ends are drivingly connected through the first conveyor belt 43, and the two opening rollers 44 and the two conveying rollers 42 in the middle are not only drivingly connected through the first conveyor belt 43, but also drivingly connected with each other through the second conveyor belt 45. The second conveyor belt 45 plays a role in increasing the tension relationship between the opening roller 44 and the conveying roller 42 and the first conveyor belt 43. Therefore, the special glass will enter the central part of the quenching tank 1 along the opening roller 44 and the conveying roller 42 respectively.

[0063] Partition plates 46 are rotatably installed at both ends of the conveying roller 42 and the opening roller 44, the partition plates 46 are fixedly connected inside the roller table 41, and one end of the opening roller 44 is connected to the servo motor 2 through a coupling;

[0064] An air cylinder rod 49 is connected to the outside of the roller table 41 through a folding plate, and the output end of the air cylinder rod 49 is fixedly connected with a sleeve plate 48;

[0065] An inclined surface table 47 is used for lifting the special glass placed on the first conveying mechanism 4, and is fixedly connected with the sleeve plate 48;

[0066] One end of the inclined surface table 47 away from the sleeve plate 48 is slidably fitted on the top of the roller table 41.

[0067] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown in Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , the quenching mechanism 7 includes a fixed rail 71, the fixed rail 71 is fixedly connected to the top of the second conveying mechanism 6, elastic piercing heads 72 are inserted at both ends of the fixed rail 71, and the outside of the elastic piercing heads 72 is fixedly connected with the fixed rail 71 through springs;

[0068] A sliding frame 73 is slidably fitted inside the fixed rail 71, and the outer end surface of the sliding frame 73 is fitted with the elastic piercing head 72 in an embedded manner, and the elastic piercing head 72 is used for limiting the sliding frame 73;

[0069] A heating rod 74 is fixedly installed inside the sliding carriage 73, and the heating rod 74 is used to heat-treat special glass. By moving the sliding carriage 73 along the fixed rail 71 to the left, at this time, the elastic piercing head 72 is fitted with the sliding carriage 73 under the action of the spring. At the same time, the heating rod 74 installed inside the sliding carriage 73 will move to a position slightly above the conveying roller 42. At this time, most of the irradiated light will be blocked and absorbed by the conveying roller 42, so as to play a role in initially heating the thick glass during the conveying process. Then, the sliding carriage 73 is moved to the right end position of the fixed rail 71. At this time, the heating rod 74 will move to a position slightly above the perforating roller 44, so as to allow part of the irradiated light to pass through the perforating roller 44 and irradiate on the end face of the thick glass, avoiding the loss of temperature at the end face. At the same time, the thick glass is in a static state at this moment. Finally, the sliding carriage 73 is moved along the fixed rail 71 to the central position. At this time, the heating rod 74 will be directly above the position between the conveying roller 42 and the perforating roller 44, so as to play a role in heating the static thick glass with a greater degree of full-range light irradiation.

[0070] A second hydraulic cylinder 75 is fixedly installed at the bottom of the top cover 8, and the output end of the second hydraulic cylinder 75 is fixedly connected with a rod sleeve 76.

[0071] A vertical rail 78 is fixedly connected to the bottom of the top cover 8, and a sliding piece 77 is slidably fitted inside the vertical rail 78. One end of the sliding piece 77 is fixedly connected with the rod sleeve 76 through a cylinder.

[0072] One end of the sliding piece 77 away from the cylinder is fixedly connected with a tension strip 79.

[0073] A flat plate seat 70 is arranged directly below the rod sleeve 76. A compensation block 701 is fixedly connected to the bottom of the flat plate seat 70. The two ends of the flat plate seat 70 are respectively rotatably connected with a first reflector 702 and a second reflector 703 through fixed shafts. The outer sides of the first reflector 702 and the second reflector 703 are both fixedly connected with the tension strip 79. Then, the second hydraulic cylinder 75 is started, so that the rod sleeve 76 connected to its output end will move upward, and the sliding piece 77 connected to the top of the rod sleeve 76 through a cylinder will move upward along the vertical rail 78. The outer side of the sliding piece 77 is connected with the tension strip 79, and the other end of the tension strip 79 is respectively fixedly connected with the first reflector 702 and the second reflector 703. The number of the tension strips 79 is two. At this time, the first reflector 702 and the second reflector 703 will deflect outward with the fixed shafts inside the flat plate seat 70 as the fulcrums, so as to make the light and heat irradiated by the heating rod 74 irradiate on the thick glass faster and more fully.

[0074] The first reflector plate 702 and the second reflector plate 703 are used to reflect the light irradiated by the heating rod 74 and irradiate it on both ends of the special glass; when the thin glass is fed into the quenching box 1, the heating rod 74 is started, and the heating rod 74 generates both heat and heat rays, and then the heat is accumulated in the quenching box 1, and then the thin glass is heated, and part of the heat rays will first irradiate on the second reflector plate 703, and then reflect from the second reflector plate 703 to the first reflector plate 702, and finally irradiate on the edge of the thin glass through the first reflector plate 702, thereby preventing the edge of the thin glass from causing micro cracks due to fast heat dissipation, and the temperature difference with the middle part can reach 10-15°C. In addition, it also keeps the thermal temperature difference between the edge and the central area of the thin glass within a certain range to avoid insufficient heat conduction.

[0075] A power source 704 is fixedly mounted on the top of the sliding frame 73, and the top of the power source 704 is fixedly connected to the compensation block 701;

[0076] A hollow ring wheel 705 is fixedly mounted on the bottom of the sliding frame 73;

[0077] The end face of the outer ring of the hollow wheel 705 is fixedly connected with a heat-insulating ring 706, and the inner sliding of the heat-insulating ring 706 is adapted to be fitted with a fitting ring 707, and the outer end of the fitting ring 707 is fixedly connected to the inner ring of the hollow wheel 705 through a short rod, wherein the hollow wheel 705 is controlled by the power supply 704. By starting the power supply 704, the hollow wheel 705 controlled by it will rotate, wherein the inner ring rotates, and the fitting ring 707 connected to the inner ring of the hollow wheel 705 through the short rod will slide out from the heat-insulating ring 706, and wrap part of the surface of the heating rod 74, thereby playing a role in progressively reducing the heating treatment of the glass and avoiding the imbalance of stress in the glass and thermal stress cracking.

[0078] When the present invention is in use: first, open the switch door at the right end of the quenching box 1, then put the special glass into the quenching box 1, and then start the servo motor 2, so that the hole-opening roller 44 connected to its output end through a coupling will rotate forward, wherein the number of hole-opening rollers 44 and conveying rollers 42 are three respectively, and they are alternately arranged on the supporting roller platform 41, wherein the hole-opening rollers 44 and conveying rollers 42 at the left and right ends are connected by transmission through No. 1 conveyor belt 43, and the two hole-opening rollers 44 and conveying rollers 42 in the middle are not only connected by transmission through No. 1 conveyor belt 43, but also connected by No. 2 conveyor belt 45, so the special glass will enter the center of the quenching box 1 along the hole-opening rollers 44 and conveying rollers 42 respectively.

[0079] When the thin glass is fed into the quenching box 1, the heating rod 74 is started. At this time, the heating rod 74 will generate heat and heat rays. Then, the heat will accumulate in the quenching box 1, and then the thin glass is heated. Among them, some heat rays will first irradiate on the second reflector 703, then be reflected from the second reflector 703 to the first reflector 702, and finally pass through the first reflector 702 and irradiate on the edge of the thin glass until the edge of the thin glass is irradiated and heated. When quenching the thick glass, the first hydraulic cylinder 5 is started, so that the second conveying mechanism 6 connected to its output end will move upward. At the same time, the quenching mechanism 7 arranged on its top will move upward together with the top cover 8 to give a certain conveying space for the thick glass. Then, the second hydraulic cylinder 75 is started, so that the rod sleeve 76 connected to its output end will move upward, and the sliding piece 77 connected to the top of the rod sleeve 76 through a column will move upward along the vertical rail 78. The outside of the sliding piece 77 is connected to the tension strip 79, and the other end of the tension strip 79 is fixedly connected to the first reflector 702 and the second reflector 703 respectively. The number of the tension strips 79 is two. At this time, the first reflector 702 and the second reflector 703 will deflect outward with the fixed shaft in the flat seat 70 as the fulcrum, so that the first reflector 702 and the second reflector 703 no longer block the heating rod 74.

[0080] By moving the sliding frame 73 along the fixed rail 71 to the left, at this time, the elastic piercing head 72 is fitted with the sliding frame 73 under the action of the spring. At the same time, the heating rod 74 installed inside the sliding frame 73 will move to a position slightly above the conveying roller 42. At this time, most of the irradiated light will be blocked and absorbed by the conveying roller 42. Then, the sliding frame 73 is moved to the right end position of the fixed rail 71. At this time, the heating rod 74 will move to a position slightly above the perforating roller 44 to avoid the end face of the glass losing temperature. At the same time, the thick glass is in a static state at this moment. Finally, the sliding frame 73 is moved along the fixed rail 71 to the central position. At this time, the heating rod 74 will be directly above the position between the conveying roller 42 and the perforating roller 44 to perform full-light illumination heating on the stationary thick glass.

[0081] By starting the power supply 704, the hollow wheel 705 controlled by it will rotate, especially the inner ring, and the fitting ring 707 connected to the inner ring of the hollow wheel 705 through the short rod will slide out from the heat-insulating ring 706 and wrap part of the surface of the heating rod 74. When the heating is completed, the pneumatic rod 49 is started, so that the sleeve plate 48 connected to the output end thereof will move toward the center of the quenching box 1 with the inclined table 47. The height of one end of the inclined platform 47 close to the glass should be lower than that of the glass, and it should be in the shape of an upward slope. Then the inclined platform 47 will squeeze the bottom of both ends of the glass until the glass is in a suspended state, and then use an external blower to blow air into the air inlet pipe 33, wherein the other end of the air inlet pipe 33 is connected to the blowing pipe 32, and then start the electric push plate 31, so that the blowing pipe 32 connected to its output end through a connecting piece will enter the quenching box 1, and respectively present a tendency to surround the glass, wherein a large number of conical holes 34 and square holes 35 are respectively opened on the inner side of the blowing pipe 32, and the outer inner diameter of the two holes is larger than the inner diameter of the inner hole, because cold air is constantly circulating in the blowing pipe 32, at this time the pressure inside the blowing pipe 32 is less than the pressure in the quenching box 1, and in addition, with the blessing of the aperture, the temperature emitted by the glass will enter the blowing pipe 32 through the conical holes 34 and the square holes 35 respectively.

[0082] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
