Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass tempering technology, specifically to a high-pressure air grid drive roller device for photovoltaic glass tempering. Background Technology

[0002] Solar photovoltaic cells are used to directly convert sunlight into electrical energy. Currently, the mainstream product is the double-glass module, which is suitable for various harsh environments and represents a new type of module with high reliability and high power generation.

[0003] Due to safety requirements, photovoltaic glass must undergo tempering: the photovoltaic glass continuously enters an electric heating furnace, where it is softened at a high temperature of approximately 700°C; it then enters a high-pressure air grid, where high-pressure air rapidly cools the glass surface. During the cooling process, the glass surface contracts rapidly, generating compressive stress, while the middle layer of the glass cools more slowly and does not have enough time to contract, forming tensile stress. This process gives the glass high strength, completing the tempering process.

[0004] Traditionally, high-pressure air grate rollers use aramid rope-wound rollers, with an average service life of 50 days. However, with the significant increase in the capacity of tempering furnaces in recent years, the lifespan of the first two aramid rope-wound rollers on the high-pressure air grate rollers has been drastically reduced, sometimes even burning out due to high temperatures within just a few days. Utility Model Content

[0005] In order to solve the problems in the prior art, this utility model provides a high-pressure air grid drive roller device for photovoltaic glass tempering processing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A high-pressure air grid drive roller device for photovoltaic glass tempering processing includes a high-pressure air grid roller conveyor, which is installed in the high-pressure air grid. The high-pressure air grid roller conveyor is divided into a heat-resistant roller conveyor area in the front part and a conventional roller conveyor area in the rear part, with the heat-resistant roller conveyor area consisting of several high heat-resistant rollers and the conventional roller conveyor area consisting of several aramid rope wound rollers.

[0008] Preferably, the high heat-resistant roller is an asbestos rope-wrapped roller.

[0009] Preferably, the asbestos rope-wrapped roller includes a roller core, and the outer layer of the roller core is fully wrapped with asbestos rope.

[0010] Preferably, the core of the asbestos rope winding roller is made of seamless steel pipe.

[0011] Preferably, the number of the high heat-resistant rollers is 1-3.

[0012] Preferably, the aramid rope winding roller includes a roller core, and the outer layer of the roller core is fully wound with aramid rope.

[0013] Preferably, the core of the aramid rope winding roller is made of seamless steel pipe.

[0014] The beneficial effects of this utility model are:

[0015] The high-pressure air grid transmission roller device of this utility model consists of a heat-resistant roller conveyor area in the front part and a conventional roller conveyor area in the rear part. When the photovoltaic glass is heated to 700°C by an electric heating furnace and enters the high-pressure air grid, it first comes into contact with the asbestos rope-wrapped roller in the heat-resistant roller conveyor area. The asbestos rope is fully wrapped around the roller, which has more durable heat resistance and can greatly improve the overall average life of the high-pressure air grid roller conveyor.

[0016] In this invention, the number of asbestos rope rollers installed is controlled to no more than three, which can effectively improve the service life of the high-pressure air grid roller and ensure that the amount of asbestos dust volatilization from the asbestos rope is controlled.

[0020] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 2 As shown, this embodiment provides a high-pressure air grid transmission roller device for photovoltaic glass tempering processing, including a high-pressure air grid roller conveyor 5, which is installed within a high-pressure air grid 4. The inlet of the high-pressure air grid roller conveyor 5 is connected to the outlet of an electric heating furnace 2 via a ceramic roller conveyor 3. The photovoltaic glass 1 is heated to 700°C by the electric heating furnace 2 and then conveyed into the high-pressure air grid roller conveyor 5 via the ceramic roller conveyor 3.

[0023] Based on the conveying direction from front to back, the high-pressure air grid roller conveyor is divided into a heat-resistant roller conveyor area at the front and a conventional roller conveyor area at the rear. The heat-resistant roller conveyor area consists of several high heat-resistant rollers, while the conventional roller conveyor area consists of several rollers wound with aramid rope.

[0024] In this embodiment, the high heat-resistant roller is an asbestos rope-wrapped roller 51. The core of the asbestos rope-wrapped roller 51 is made of precision-drawn seamless steel pipe 512, and the outer layer is fully wrapped with asbestos rope 511. When the photovoltaic glass is heated to 700°C in an electric heating furnace and then conveyed into the high-pressure air grid via a ceramic roller conveyor, it first comes into contact with the asbestos rope-wrapped roller 51. Its full wrapping with asbestos rope provides more durable heat resistance, thus greatly extending its service life.

[0025] In this embodiment, the number of asbestos rope rollers 51 installed is controlled to no more than 3, which can effectively improve the service life of the high-pressure air grid roller and ensure that the amount of asbestos dust volatilization from the asbestos rope is controlled.

[0026] In this embodiment, the core of the aramid rope-wound roller 52 is made of seamless steel pipe, and the outer layer of the roller core is fully wrapped with aramid rope. When the photovoltaic glass comes into contact with the aramid rope-wound roller 52, its temperature has been appropriately reduced.

[0027] The working principle of this utility model is as follows:

[0028] During use, the photovoltaic glass is first heated to 700℃ in an electric furnace. When it is conveyed into the high-pressure air grid via the ceramic roller conveyor 3, it first comes into contact with the asbestos-wrapped rope roller 51, and then with the aramid-wrapped rope roller 52. The asbestos-wrapped rope roller 51 has more durable heat resistance, which can make the overall average life of the high-pressure air grid roller conveyor reach 50 days.
