Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, and in particular to a hot air circulation structure for a tempered glass homogenizing furnace. Background Technology

[0002] In the tempered glass production process, the homogenizing furnace is one of the key pieces of equipment, and its hot air circulation structure plays a crucial role in the quality and production efficiency of the tempered glass. Good hot air circulation ensures uniform temperature within the furnace, enabling the tempered glass to achieve ideal performance during the homogenization process. With the continuous growth of market demand for tempered glass and increasingly stringent quality requirements, higher demands are being placed on the performance of the homogenizing furnace's hot air circulation structure. How to achieve efficient, stable, and precisely adjustable hot air circulation has become a pressing technical problem to be solved in the current tempered glass production field.

[0003] However, the traditional hot air circulation structure used in tempered glass homogenizing furnaces makes it difficult to flexibly control the hot air flow rate according to different production process requirements. In actual production, the hot air flow rate requirements vary greatly for tempered glass of different specifications and quality requirements during homogenization. If the hot air flow rate cannot be effectively adjusted, it can easily lead to uneven temperature inside the furnace, which in turn affects the quality of the tempered glass and reduces production efficiency.

[0004] For example, when producing thick tempered glass, a larger hot air flow rate is needed to accelerate heat transfer and allow the glass interior to quickly reach the temperature required for homogeneity. However, existing hot air circulation structures may not be able to increase the hot air flow rate in a timely and accurate manner, resulting in excessively long glass heating times. This not only wastes energy but may also cause overheating of the glass surface, affecting product quality. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hot air circulation structure for a tempered glass homogenizing furnace includes a homogenizing furnace body. Multiple equally spaced electric heating tubes are installed on both sides of the inner wall of the homogenizing furnace body. A conveyor belt is installed on one outer wall of the homogenizing furnace body. A support plate is installed directly above the bottom inner wall of the homogenizing furnace body. The structure also includes: an adjustment mechanism: the adjustment mechanism includes an air box installed on one outer wall of the homogenizing furnace body. A fan is installed on the inner wall of the air box. An air supply pipe is connected to the top outer wall of the air box. A return air pipe is connected to the bottom outer wall of the air box. Protective covers are installed at the ends of the air supply pipe and the return air pipe away from the air box. Baffles are installed on the inner walls of the air supply pipe and the return air pipe. Multiple elliptical holes of unequal radii are opened inside the baffles. A baffle is attached to the top outer wall of the baffles. Fixing blocks are fixed to one outer wall of the air supply pipe and the return air pipe; and a filtering mechanism: the filtering mechanism is located on the inner wall of the air box.

[0008] The inner wall of the air box in this design is equipped with a fan. By starting the fan, air is circulated in the air box, air supply pipe, and return air pipe, thereby realizing the hot air circulation in the homogenizing furnace. At the same time, the baffles installed on the inner walls of the air supply pipe and return air pipe have multiple elliptical holes with different radii. By moving the baffles, the relative position of the baffles with the elliptical holes on the baffles is changed, thereby adjusting the opening size of the elliptical holes and controlling the airflow in the air supply pipe and return air pipe to meet different production process requirements.

[0010] This solution uses connecting grooves inside the connecting frame to fix the filter plates. The three filter plates are arranged in descending order of pore size, forming a multi-stage filtration structure. The filter plate with the larger pore size is located at the front end of the airflow inlet, which can first intercept and filter larger dust and impurities in the air. The filter plate with the middle pore size further refines the air after the initial filtration, while the filter plate with the smallest pore size intercepts tiny dust and impurities, ensuring that the air entering the hot air circulation system reaches a high level of cleanliness.

Multiple equally spaced electric heating tubes are installed on both sides of the inner wall of the homogenizing furnace body. A conveyor belt is installed on one outer wall of the homogenizing furnace body. A support plate is installed directly above the bottom inner wall of the homogenizing furnace body.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The hot air circulation structure for tempered glass homogenizing furnaces disclosed in this utility model is mainly applied to traditional hot air circulation structures for tempered glass homogenizing furnaces. These structures are difficult to control the hot air flow rate flexibly according to different production process requirements, which can easily lead to uneven temperature inside the furnace and thus affect the quality of the tempered glass.

[0019] Reference Figure 1 , Figure 2 and Figure 3 A hot air circulation structure for a tempered glass homogenizing furnace includes a homogenizing furnace body 1, multiple equally spaced electric heating tubes 3 installed on both sides of the inner wall of the homogenizing furnace body 1, a conveyor belt 2 installed on one outer wall of the homogenizing furnace body 1, and a support plate 4 installed directly above the bottom inner wall of the homogenizing furnace body 1. It also includes: an adjustment mechanism: the adjustment mechanism includes an air box 6 installed on one outer wall of the homogenizing furnace body 1, a fan installed on the inner wall of the air box 6, an air supply pipe 5 connected to the top outer wall of the air box 6, and a return air pipe 7 connected to the bottom outer wall of the air box 6. Protective covers 10 are installed at the ends of the air supply pipe 5 and the return air pipe 7 away from the air box 6. Partitions 11 are installed on the inner walls of the air supply pipe 5 and the return air pipe 7. Multiple elliptical holes of unequal radius are opened inside the partitions 11. A baffle 12 is attached to the top outer wall of the partition 11. Fixing blocks 13 are fixed to one outer wall of the air supply pipe 5 and the return air pipe 7. A filtration mechanism: the filtration mechanism is located on the inner wall of the air box 6.

[0020] In this design, a fan is installed on the inner wall of the air box 6. By starting the fan, air is circulated in the air box 6, the air supply pipe 5, and the return air pipe 7, thereby realizing the circulation of hot air in the homogenizing furnace. At the same time, the baffles 11 installed on the inner walls of the air supply pipe 5 and the return air pipe 7 have multiple elliptical holes with different radii. By moving the baffle 12, its relative position with the elliptical holes on the baffle 11 is changed, thereby adjusting the opening size of the elliptical holes and controlling the airflow in the air supply pipe 5 and the return air pipe 7 to meet different production process requirements.

[0021] The partition 11 has multiple elliptical holes with different radii inside. By pushing the baffle 12 to block the elliptical holes on the partition 11, the airflow is changed.

[0022] Specifically, a push rod is connected to one side of the outer wall of the baffle 12. The outer wall of the push rod is covered with a sealing sleeve, which serves to prevent air leakage.

[0023] Reference Figure 1 and Figure 4 In a preferred embodiment, the filtration mechanism includes a connecting frame 14 disposed on the inner wall of the air box 6. The inner wall of the connecting frame 14 is connected to three filter plates 9 with different aperture sizes. Each of the three filter plates 9 has multiple filter holes distributed at equal intervals inside.

[0024] The filter plates 9 are fixed by the connecting groove inside the connecting frame 14. At the same time, the three filter plates 9 are arranged in order of decreasing pore size to form a multi-stage filtration structure. The filter plate 9 with the larger pore size is located at the front end of the airflow inlet. It can first intercept and filter larger dust and impurities in the air. The filter plate 9 with the middle pore size further refines the air after the initial filtration. The filter plate 9 with the smallest pore size intercepts tiny dust and impurities to ensure that the air entering the hot air circulation system reaches a high level of cleanliness.

[0025] Among them, the pore size of the three filter plates 9 decreases sequentially, with the smallest pore size of one filter plate 9 closest to the fan. By installing a combination of three filter plates 9 at the air inlet, the outermost filter plate 9 can filter larger dust particles, the middle filter plate 9 further removes medium-sized particles, and the innermost filter plate 9 can intercept tiny dust and impurities.

[0026] Specifically, the connecting frame 14 has three connecting grooves inside that match the three filter plates 9, and the connecting frame 14 is used to provide installation positions for the three filter plates 9.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, two symmetrically distributed latches 8 are installed on the outer wall of the bellows 6 on the side away from the homogenizer body 1. The latches 8 are used to fix the connecting frame 14.

[0028] Working principle: During use, tempered glass is conveyed by conveyor belt 2 to the support plate 4 inside the homogenizing furnace body 1. At this time, multiple equally spaced electric heating tubes 3 installed on both sides of the inner wall of the homogenizing furnace body 1 are energized to provide heat to the furnace, causing the furnace temperature to gradually rise. Then, by starting the fan, air enters the air box 6 and participates in the circulation process. During this process, the air passes through a filtration mechanism and is filtered by a triple filter plate 9, intercepting dust and impurities to ensure that the air entering the hot air circulation system reaches a high level of cleanliness, preventing dust and impurities from accumulating in the air duct. The fan drives the hot air into the air supply duct 5. Both the supply air duct 5 and the return air duct 7 are equipped with baffles 11 on their inner walls. By moving the baffle 12, the relative position of the baffle 12 with the elliptical hole on the baffle 11 is changed, thereby adjusting the opening size of the elliptical hole. When the baffle 12 partially blocks the elliptical hole, the effective flow area of ​​the air duct decreases, and the airflow decreases accordingly. When the baffle 12 is moved away, the opening of the elliptical hole increases, the effective flow area of ​​the air duct increases, and the airflow increases accordingly. The air passes through the protective cover 10 to reach the furnace and is blown onto the surface of the tempered glass to heat the glass. Then, the hot air returns to the blower through the return air duct 7 and is sent back into the air inlet duct, thus forming a cycle.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
