Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production technology, and in particular to an annealing device for tempered glass production. Background Technology
[0002] Annealing tempered glass is a heat treatment process aimed at reducing or eliminating permanent stresses generated during the forming or hot processing of glass, thereby improving its performance. The thermal equipment used for tempered glass annealing is called an annealing furnace. Currently, in tempered glass production lines, tempered glass needs to be cooled to room temperature in a cooling chamber. However, the heat generated in the cooling chamber is not utilized, resulting in energy waste. Furthermore, the cooling chamber directly and suddenly cools the tempered glass, which can easily lead to excessive temperature differences and cracking, resulting in a low yield. Additionally, the heat generated during cooling cannot be dissipated, leading to poor cooling efficiency within the cooling chamber. Therefore, we propose an annealing device for tempered glass production to address these issues. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of the prior art by providing an annealing apparatus for tempered glass production.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an annealing device for tempered glass production, comprising: a roller conveyor frame, a cooling box, a pre-cooling box, an air pump, an exhaust pipe, a first inlet, an air inlet, a second inlet, a main pipe, a connecting pipe, a branch pipe, a cooling shroud, and a connecting chamber. Cooling boxes are fixedly installed on both the upper and lower left sides of the roller conveyor frame, and pre-cooling boxes are fixedly installed on both the upper and lower right sides of the roller conveyor frame. A connecting chamber is fixedly installed between the cooling box and the pre-cooling box. Multiple air pumps are provided between the cooling box and the pre-cooling box. The air pump is located on the left side... An exhaust duct is fixedly installed, with its left side extending into the interior of the cooling box. Multiple first ports are fixedly installed on the surface of the exhaust duct. An air inlet duct is fixedly installed on the right side of the exhaust pump, extending into the interior of the pre-cooling box. Multiple second ports are fixedly installed on the surface of the air inlet duct. A main pipe is fixedly installed on the surface of the cooling box. A connecting pipe is fixedly installed at the top center of the main pipe. Multiple branch pipes are fixedly installed at the bottom of the main pipe, extending into the interior of the cooling box. A cooling cover is fixedly installed at the bottom of each branch pipe.
[0005] Preferably, the two cooling boxes are arranged in a symmetrical top-bottom configuration, and the cooling covers are distributed equidistantly inside the cooling boxes.
[0006] Preferably, the two exhaust pipes are arranged in a symmetrical structure, and the first pipe openings are distributed equidistantly on the surface of the exhaust pipes, and the two air inlet pipes are arranged in a symmetrical structure, and the second pipe openings are distributed equidistantly on the surface of the air inlet pipes.
[0007] Preferably, the two precooling boxes are arranged in a symmetrical top-bottom configuration.
[0008] Preferably, the height of the exhaust duct is higher than that of the cooling shroud.
[0009] Preferably, the second port is configured with a downwardly inclined structure.
[0010] Compared with the prior art, this utility model has the following advantages:
[0011] (1) The cooling fan is connected to the connecting pipe so that the cooling fan can input cold air into the main pipe. Then the cold air inside the main pipe can be distributed to each branch pipe until it flows out from the cooling cover. The cold air flowing out can blow and cool the tempered glass that passes through. The two cooling boxes are symmetrically distributed on the upper and lower sides of the roller conveyor frame, so that the front and back sides of the tempered glass can be blown and cooled at the same time, which can improve the cooling effect.
[0012] (2) By starting the air pump, the heat generated inside the cooling box can be drawn into the exhaust pipe from the first port, and the heat inside the exhaust pipe can be drawn into the air inlet pipe, and the heat inside the air inlet pipe can flow out into the pre-cooling box from the second port, so that the temperature inside the pre-cooling box is certain and the temperature is definitely lower than the stable temperature of the tempered glass itself. This allows the tempered glass to be cooled down slowly after passing through the pre-cooling box, so that the cooling of the tempered glass can be gradual and that the temperature difference is not too large, which may cause it to crack. At the same time, by extracting and using the heat generated inside the cooling box, the heat can be recovered and reused, which can prevent the waste of resources. The cooling effect inside the cooling box can also be improved while the heat is extracted and used. Attached Figure Description

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0021] like Figure 1-6 An annealing apparatus for tempered glass production, as shown, includes: a roller conveyor 1, a cooling box 2, a pre-cooling box 3, an air pump 4, an exhaust pipe 5, a first inlet 6, an air inlet 7, a second inlet 8, a main pipe 9, a connecting pipe 10, a branch pipe 11, a cooling hood 12, and a connecting chamber 13. The cooling box 2 is fixedly installed on both the upper and lower left sides of the roller conveyor 1, and the pre-cooling box 3 is fixedly installed on both the upper and lower right sides of the roller conveyor 1. A connecting chamber 13 is fixedly installed between the cooling box 2 and the pre-cooling box 3. Multiple air pumps 4 are provided between the cooling box 2 and the pre-cooling box 3. The air pumps 4 are fixedly installed on the left side... The cooling box 2 is equipped with an exhaust pipe 5, which extends to the inside of the cooling box 2 on the left side. Multiple first ports 6 are fixedly installed on the surface of the exhaust pipe 5. An air inlet pipe 7 is fixedly installed on the right side of the air pump 4, which extends to the inside of the pre-cooling box 3 on the right side. Multiple second ports 8 are fixedly installed on the surface of the air inlet pipe 7. A main pipe 9 is fixedly installed on the surface of the cooling box 2. A connecting pipe 10 is fixedly installed at the top center of the main pipe 9. Multiple branch pipes 11 are fixedly installed at the bottom of the main pipe 9, and the bottom of the branch pipes 11 extends to the inside of the cooling box 2. A cooling cover 12 is fixedly installed at the bottom of each branch pipe 11.
[0022] In this embodiment, the two cooling boxes 2 are arranged in a symmetrical structure, and the cooling covers 12 are distributed in an equidistant structure inside the cooling boxes 2.
[0023] In practical use, the cooling fan is connected to the connecting pipe 10, allowing the cooling fan to input cold air into the main pipe 9. The cold air inside the main pipe 9 can then be distributed to each branch pipe 11 until it flows out from the cooling cover 12. The outflowing cold air can then blow and cool the tempered glass. Furthermore, the two cooling boxes 2 are symmetrically distributed on the upper and lower sides of the roller conveyor frame 1, so that both sides of the tempered glass can be cooled simultaneously, which can improve the cooling effect.
[0024] In this embodiment, the two exhaust pipes 5 are arranged in a symmetrical structure, and the first pipe openings 6 are distributed equidistantly on the surface of the exhaust pipes 5. The two air inlet pipes 7 are arranged in a symmetrical structure, and the second pipe openings 8 are distributed equidistantly on the surface of the air inlet pipes 7.
[0025] In practical use, by activating the air pump 4, the heat generated inside the cooling box 2 can be drawn into the exhaust pipe 5 through the first port 6, and the heat inside the exhaust pipe 5 can be drawn into the air inlet pipe 7. The heat inside the air inlet pipe 7 can flow out through the second port 8 into the pre-cooling box 3, so that the temperature inside the pre-cooling box 13 reaches a certain level, which is definitely lower than the stable temperature of the tempered glass itself. This allows the tempered glass to be cooled down slowly after passing through the pre-cooling box 13, so that the cooling of the tempered glass can be gradual and not cause it to crack due to excessive temperature difference. At the same time, by extracting and using the heat generated inside the cooling box 2, the heat can be recovered and reused, which can prevent resource waste. In addition, the cooling effect inside the cooling box 2 can be improved while extracting and using the heat.
[0026] In this embodiment, the two precooling boxes 3 are arranged in a symmetrical top-to-bottom configuration.
[0027] In practical use, the tempered glass can be slowly cooled on both sides simultaneously through the two pre-cooling boxes 3.
[0028] In this embodiment, the height of the exhaust pipe 5 is higher than that of the cooling shroud 12.
[0029] In practical use, the height of the exhaust pipe 5 is higher than that of the cooling cover 12, so that the exhaust pipe 5 will not draw away the cold air flowing out of the cooling cover 12. When the cold air comes into contact with the tempered glass surface, the heat generated will dissipate upwards, and the exhaust pipe 5 can extract the heat dissipated upwards.
[0030] In this embodiment, the second port 8 is arranged with a downward tilting structure.
[0031] In actual use, the second port 8 is set with a downward tilt structure so that the heat flowing out of the second port 8 can be directed to the surface of the tempered glass.
[0032] Furthermore, the structure, working principle, and corresponding supporting equipment of the roller conveyor frame 1 all adopt existing technologies, which will not be described in detail here.
[0033] Furthermore, the structure, working principle, and corresponding control equipment of the air pump 4 all adopt existing technologies, which will not be described in detail here.
[0034] The working principle of the annealing device for tempered glass production mentioned in this utility model is as follows:
[0035] In use, the cooling fan is connected to the connecting pipe 10, allowing the cooling fan to input cold air into the main pipe 9. The cold air inside the main pipe 9 can then be distributed to each branch pipe 11 until it flows out from the cooling cover 12. The outflowing cold air can cool the tempered glass. Furthermore, the two cooling boxes 2 are symmetrically distributed on the upper and lower sides of the roller conveyor frame 1, so that both sides of the tempered glass can be cooled simultaneously, which can improve the cooling effect.
[0036] Simultaneously, by activating the air pump 4, the heat generated inside the cooling box 2 can be drawn into the exhaust pipe 5 through the first port 6, and the heat inside the exhaust pipe 5 can be drawn into the air inlet pipe 7. The heat inside the air inlet pipe 7 can flow out through the second port 8 into the pre-cooling box 3, so that the temperature inside the pre-cooling box 13 reaches a certain level, which is definitely lower than the stable temperature of the tempered glass itself. This allows the tempered glass to be cooled down slowly after passing through the pre-cooling box 13, so that the cooling of the tempered glass can be gradual and that it will not crack due to excessive temperature difference. At the same time, by extracting and using the heat generated inside the cooling box 2, the heat can be recovered and reused, which can prevent resource waste. In addition, the cooling effect inside the cooling box 2 can be improved while extracting and using the heat.
