Description

Technical Field

[0001] This invention relates to the field of glass deep processing equipment technology, and in particular to an improved tempered glass air-cooling channel and its cooling method. Background Technology

[0002] Float glass is a flat glass produced by the float process, which involves floating molten glass on the surface of liquid tin to form a smooth surface, uniform thickness, and high transparency. It is widely used in construction, automotive, and electronics industries. In the production process of float glass, the glass heated to near its softening point needs to be rapidly and uniformly cooled (quenched) through a strong cooling channel composed of upper and lower air grids to form the required surface compressive stress. Currently, the mainstream equipment uses heat-resistant ceramic roller conveyors to transport the glass through this air-cooling channel.

[0003] However, while the conveyor rollers below the traditional equipment support and transport glass, the rollers themselves severely interfere with the airflow field from the lower air grille, resulting in an airflow obstruction effect. Furthermore, the rollers themselves, which are in contact with the high-temperature glass, are affected by the heat transfer effect. After long-term operation, the heat accumulated by the rollers themselves will affect the heat dissipation effect of the glass transported subsequently. Therefore, the invention of an efficient cooling solution that can effectively compensate for this non-uniformity and does not interrupt production has become an urgent problem to be solved in this field. Summary of the Invention

[0004] This invention discloses an improved tempered glass air-cooling channel and its cooling method, aiming to solve the technical problems that traditional glass cooling technologies and equipment need to be improved in terms of working efficiency and completeness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved tempered glass air-cooled tunnel includes a passageway. Several rotating shafts driven by external motors are rotatably mounted inside the lower part of the passageway. Several evenly distributed conveyor wheels are sleeved on the outer side of each rotating shaft. The conveyor wheels on the outer sides of two adjacent rotating shafts are staggered. Several evenly distributed corrugated tubes are also installed through the lower part of the passageway. Several auxiliary air nozzles are connected to the ends of the corrugated tubes, and several main air nozzles are connected to the middle of the corrugated tubes. The auxiliary air nozzles are distributed horizontally and interspersed with each conveyor wheel, and vertically distributed at the bottom of the conveyor wheels. The main air nozzles are distributed between each group of rotating shafts, and the air output of the main air nozzles is greater than that of the auxiliary air nozzles. Several rows of upper air nozzles are connected through the upper part of the passageway.

[0007] By modifying the mechanism for conveying tempered glass and the flow path of cooling airflow based on traditional tempered glass processing technology, this equipment differs from traditional equipment that uses solid ceramic rollers to convey tempered glass. Instead, it utilizes a rotating shaft with an interlaced distribution of conveyor wheels to alternately convey high-temperature glass. This reduces the impact of the conveyor wheels' own temperature on the glass and the impact of their volume blocking airflow, thereby improving the uniformity of heat dissipation during glass conveying and reducing interference from external factors. Secondly, unlike traditional equipment that uses direct airflow to cool the glass, this equipment uses a specially structured corrugated pipe connected to the main and auxiliary air nozzles. The position and air volume of the main and auxiliary air nozzles are specifically limited, which significantly improves the uniformity of cooling the lower surface of the glass. At the same time, it can also cool the conveyor wheels, further reducing the impact of the conveyor wheels' own temperature on the glass.

[0008] In a preferred embodiment, the conveying wheel includes a ceramic roller body fixedly installed on the outside of the rotating shaft. The outside of the ceramic roller body is provided with several evenly distributed cooling zones. A metal sleeve is fixedly fitted onto the outside of the ceramic roller body. The metal sleeve wraps around the outside of the cooling zones and supports the high-temperature glass.

[0009] By setting the traditional solid ceramic conveying roller to be composed of several staggered individual ceramic rollers and a rotating shaft, the staggered and interwoven ceramic rollers can minimize the impact on heat transfer to the tempered glass above. At the same time, the metal kit on the outside of the ceramic roller and the cooling zone inside the ceramic roller can achieve good self-cooling function with the help of the auxiliary air nozzle, thereby greatly improving the uniformity of cooling of the lower surface of the glass.

[0010] In a preferred embodiment, each of the cooling zones has a supporting fin distributed within it, and the fin is fixedly connected to the metal assembly.

[0011] By incorporating a finned structure connected to a metal assembly along the interior of the cooling zone on the basis of the ceramic roller, the fins can provide support for the metal assembly and improve its structural strength. On the other hand, the fins can work in conjunction with the operation of the auxiliary air nozzle to improve the heat dissipation efficiency of the metal assembly, maintain the uniformity of cooling of the lower surface of the glass, and ensure the proper functioning of the equipment.

[0012] In a preferred embodiment, the auxiliary nozzle includes a direct current nozzle that is connected through to the top of the protruding end, and a split nozzle is symmetrically mounted on both sides of the direct current nozzle, with the split nozzles facing both sides of the cooling zone.

[0013] By configuring the auxiliary air nozzle to consist of one direct nozzle and two split nozzles, the direct nozzle can directly cool the lower surface of the glass, while the split nozzles can synchronously cool the conveyor wheels on both sides, thereby maintaining the uniformity of cooling of the lower surface of the glass and ensuring the proper operation of the equipment.

[0014] A cooling method for an improved tempered glass air-cooled channel includes the following steps;

[0015] S1: The worker starts the entire equipment, and the external motor drives several of the rotating shafts to rotate, transporting the glass that has undergone high-temperature treatment from the end of the passageway.

[0016] S2: Driven by the rotating shaft, the high-temperature glass will pass through the surface of the interlaced conveyor wheels in sequence;

[0017] S3: During this period, the corrugated pipe and the upper air nozzle connected to the external pump introduce cooling gas into the interior of the passage, and the upper air nozzle directly cools and blows on the upper surface of the high-temperature glass.

[0018] S4: The cooling gas conducted from inside the corrugated tube will be simultaneously discharged from inside the main air nozzle and the auxiliary air nozzle to perform constant temperature cooling on the lower surface of the high-temperature glass and the conveying wheel. Thanks to the interlacing distribution of the conveying wheel and the programmed control of the air output of the main air nozzle and the auxiliary air nozzle, the uniformity of cooling of the lower surface of the glass can be maintained.

[0019] S5: The cooled tempered glass is removed from the other end of the passageway.

[0020] As can be seen from the above, the present invention provides the following technical effects.

[0021] Improvements were made to the equipment for processing high-temperature glass based on traditional tempered glass processing technology;

[0022] Firstly, unlike traditional equipment that uses solid ceramic rollers to convey tempered glass, this equipment uses rotating shafts with interspersed conveyor wheels to alternately convey high-temperature glass. This reduces the impact of the conveyor wheels' own temperature on the glass and the impact of their own volume on airflow, thereby improving the uniformity of heat dissipation during glass conveying and reducing interference from external factors.

[0023] Secondly, unlike traditional equipment that uses direct current airflow to cool the glass, this equipment uses a specially structured corrugated pipe connected to the main and auxiliary air nozzles. The position and air volume of the main and auxiliary air nozzles are specifically limited, which greatly improves the uniformity of cooling of the lower surface of the glass. At the same time, it can also cool the conveyor wheel, further reducing the impact of the conveyor wheel's own temperature on the glass and improving the operational reliability of traditional high-temperature glass processing equipment.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] The improved tempered glass air-cooling channel and its cooling method disclosed in this invention are mainly applied to the cooling process of high-temperature tempered glass.

[0036] Reference Figures 1 to 9An improved tempered glass air-cooled channel includes a passageway 1. Several rotating shafts 2 driven by external motors are rotatably installed inside the lower part of the passageway 1. Several evenly distributed conveyor wheels 3 are sleeved on the outer side of each rotating shaft 2. Several evenly distributed corrugated pipes 4 are also installed through the lower part of the passageway 1. Several auxiliary air nozzles 6 are connected through the ends of the corrugated pipes 4. Several main air nozzles 5 are connected through the middle of the corrugated pipes 4. The auxiliary air nozzles 6 are located horizontally between each conveyor wheel 3 and vertically close to the conveyor wheel 3. The main air nozzles 5 are distributed between each group of rotating shafts 2, and the air output of the main air nozzles 5 is greater than that of the auxiliary air nozzles 6. Several rows of upper air nozzles 7 are connected through the upper part of the passageway 1.

[0037] In this embodiment: the worker starts the entire equipment, and the external motor drives several rotating shafts 2 to rotate, transporting the high-temperature treated glass from the end of the passageway 1. Driven by the rotating shafts 2, the high-temperature glass will pass through the surface of the interspersed conveyor wheels 3 in sequence. During this period, the corrugated pipe 4 and the upper air nozzle 7 connected to the external pump introduce cooling gas into the interior of the passageway 1. The upper air nozzle 7 directly cools and blows on the upper surface of the high-temperature glass. The cooling gas conducted from inside the corrugated pipe 4 will be simultaneously discharged from inside the main air nozzle 5 and the auxiliary air nozzle 6 to perform constant temperature cooling on the lower surface of the high-temperature glass and the conveyor wheels 3. Thanks to the interspersed distribution of the conveyor wheels 3 and the programmed control of the air output of the main air nozzle 5 and the auxiliary air nozzle 6, the uniformity of cooling of the lower surface of the glass can be maintained. Finally, the cooled tempered glass is moved out from the other end of the passageway 1.

[0038] It is worth noting that, such as Figure 9 As shown, several conveying wheels 3 located on the outer sides of two adjacent rotating shafts 2 are staggered in sequence. In this way, the contact time between the lower surface of the glass and the surface of the conveying wheel 3 can be reduced. In addition, with the special "corrugated" structure of the corrugated tube 4, the lower surface of the glass can be cooled and the staggered conveying wheels 3 can be cooled precisely.

[0039] Specifically, the corrugated pipe 4 can be composed of several straight pipes and connected to the main air nozzle 5, and the corrugated pipe 4 and the auxiliary air nozzle 6 can be connected by a three-way valve.

[0040] The inner wall of the passageway 1 is fixedly equipped with several side plates 8, which support the rotating shaft 2, the corrugated pipe 4 and the upper air nozzle 7 in sequence. A tray 9 is placed on the upper part of the passageway 1, and the upper air nozzle 7 passes through the bottom of the tray 9. At the same time, the tray 9 supports the upper air nozzle 7.

[0041] Furthermore, a chamber 101 is provided in the middle of the passageway 1, and the rotating shaft 2 and the conveying wheel 3 are distributed in the chamber 101.

[0042] Reference Figures 4 to 7In a preferred embodiment, the conveying wheel 3 includes a ceramic roller body 301 fixedly installed on the outside of the rotating shaft 2. The outer side of the ceramic roller body 301 is provided with a plurality of evenly distributed cooling zones 302. A metal kit 303 is sleeved and fixed on the outer side of the ceramic roller body 301. The metal kit 303 wraps around the outer side of the cooling zone 302 and supports the high-temperature glass.

[0043] When the conveyor wheel 3 rotates, the metal kit 303 located outside the ceramic roller 301 will rotate synchronously and convey the tempered glass on top. Meanwhile, the cooling gas blown in the auxiliary air nozzle 6 will flow into the interior of the cooling zone 302, thereby cooling the metal kit 303 and reducing the impact of the temperature of the conveyor wheel 3 itself on the glass.

[0044] Each cooling zone 302 has a supporting fin 304 distributed inside. The fin 304 is fixedly connected to the metal kit 303. On the one hand, the fin 304 provides internal support for the metal kit 303 and maintains the structural strength of the metal kit 303. On the other hand, with the cooling gas ejected from the auxiliary air nozzle 6, the fin 304 improves the cooling efficiency of the metal kit 303.

[0045] Specifically, refer to Figure 8 In a preferred embodiment, the end of the corrugated tube 4 is provided with an outward protrusion 401, which is symmetrically distributed between the two conveying wheels 3 in the horizontal direction. Each auxiliary air nozzle 6 is installed at the outward protrusion 401. The auxiliary air nozzle 6 includes a direct current nozzle 601 that is connected through to the top of the outward protrusion 401. A branch nozzle 602 is symmetrically installed on both sides of the direct current nozzle 601, and the branch nozzle 602 faces both sides of the cooling zone 302.

[0046] When cooling gas is introduced into the corrugated tube 4, the cooling gas will be sprayed out sequentially from the direct nozzle 601 and the split nozzle 602 located at the top of the protruding end 401. The cooling gas sprayed from the direct nozzle 601 will directly act on the bottom of the high-temperature glass, while the gas sprayed from the split nozzle 602 is inclined and blows towards the conveyor wheels 3 on the upper left and right sides, and flows through the cooling zone 302, thereby cooling the metal kit 303 that is in direct contact with the high-temperature glass, so as to avoid affecting the cooling effect of the subsequent glass.

[0047] Working Principle: During operation, the worker starts the entire equipment. An external motor drives several rotating shafts 2 to rotate, conveying the high-temperature treated glass from the end of the tunnel 1. Driven by the rotating shafts 2, the high-temperature glass is conveyed along the surface of the conveyor wheels 3. During this process, the corrugated pipe 4 and the upper air nozzle 7, connected to the external pump, introduce cooling gas into the tunnel 1. The upper air nozzle 7 directly and evenly cools the upper surface of the high-temperature glass. The cooling gas flowing through the corrugated pipe 4 is simultaneously discharged from the main air nozzle 5 and the auxiliary air nozzle 6. The main air nozzle 5 directly... The lower surface of the high-temperature glass is cooled by blowing air through it. The gas exiting from the auxiliary nozzle 6 is divided into two parts. The cooling gas ejected from the direct nozzle 601 acts directly on the bottom of the high-temperature glass, while the gas ejected from the split nozzle 602 passes through the cooling zone 302 inside the conveyor wheel 3, thereby cooling the metal component 303 that is in direct contact with the high-temperature glass. By setting the main nozzle 5 and the auxiliary nozzle 6 on the surface of the "corrugated" corrugated tube 4, dual cooling of the glass and the conveyor wheel 3 is achieved. Finally, the cooled tempered glass is removed from the other end of the passageway 1.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
