Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment. Specifically, the utility model relates to a glass tempering furnace. Background Art

[0002] During the production process of photovoltaic glass, when it undergoes high-temperature processing in a horizontal tempering furnace and the temperature at the lower part of the furnace body remains high, the glass will be damaged by heat burns during the processing due to the ultra-high temperature, which will reduce the quality of the glass. The main reason is that during the continuous heating process of the tempering furnace, the energy generated by heating accumulates in a certain part due to the narrow internal space of the furnace chamber, and the energy cannot be evenly dispersed, resulting in an ultra-high temperature at a certain part inside the tempering furnace chamber. When the glass passes through this ultra-high temperature part, the glass will be damaged by heat burns.

[0003] In the prior art, manufacturers use chemical products to reduce the heat burns of the glass, but it can only improve within a certain period of time, and the guarantee time is not long, and it cannot completely solve the problem of glass heat burns.

[0004] For example, the patent document with the publication number CN103274586A discloses a glass tempering furnace, which includes an upper furnace chamber, a lower furnace chamber, a transmission roller path, heating wires, and radiation plates; it also includes a radiation tube group and a convection tube. The radiation tube group is hoisted inside the upper furnace chamber and is arranged below the heating wires. The radiation tube group is formed by connecting a plurality of parallel radiation tubes side by side. The convection tube is hoisted below the radiation tube, and the air inlet end of the convection tube is connected to a fan, and air injection holes are arranged on the convection tube. The technical solution disclosed in this patent document also cannot solve the above-mentioned technical problems. Summary of the Utility Model

[0005] The utility model provides a glass tempering furnace with the aim of improving the quality of glass products.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a glass tempering furnace, including a conveying roller and a heating radiation plate. The heating radiation plate is located below the conveying roller, and the distance between the conveying roller and the heating radiation plate is 145 - 155 cm.

[0007] The distance between the conveying roller and the heating radiation plate is 150 cm.

[0008] The material of the conveying roller is ceramic.

[0009] The heating radiation plate is arranged on a support member, and a plurality of support members are provided.

[0010] The material of the support member is ceramic.

[0011] Air injection pipes are arranged above and below the conveying roller.

[0012] The glass tempering furnace of the present utility model reduces the height of the internal heating radiation plate, so that the horizontal ceramic rollers of the tempering furnace body are spaced apart from the heating radiation plate, thereby reducing the heat of the lower part of the tempering furnace on the lower surface of the glass, so as to achieve the effect of ensuring the quality of tempered glass, not easily causing thermal burns, and improving the quality of glass products.

[0017] Next, with reference to the drawings, through the description of the embodiments, the specific embodiments of the present utility model will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model, and to facilitate its implementation.

[0018] As Figure 1 and Figure 2 shown, the present utility model provides a glass tempering furnace, which includes a furnace body, a conveying roller 2 and a heating radiation plate 5. The heating radiation plate 5 is located below the conveying roller 2, and the distance between the conveying roller 2 and the heating radiation plate 5 is 145-155 cm.

[0019] Specifically, as Figure 1 shown, the conveying roller 2 and the heating radiation plate 5 are located inside the furnace body. A plurality of conveying rollers 2 are provided, and the conveying roller 2 is used for conveying glass.

[0020] As Figure 1 and Figure 2 shown, the heating radiation plate 5 is arranged on the support member 4. A plurality of support members 4 are provided. The heating radiation plate 5 is in a horizontal state, and the heating radiation plate 5 is parallel to the conveying roller 2. The support member 4 is used to provide a supporting effect on the heating radiation plate 5. The support member 4 is fixedly arranged inside the furnace body, and the heating tube is located below the heating radiation plate 5.

[0021] Preferably, the distance between the conveying roller 2 and the heating radiation plate 5 is 150 cm. The height of the conveying roller 2 remains unchanged, and the height of the heating radiation plate 5 is reduced to widen the spacing between the heating radiation plate 5 and the glass being processed on the conveying roller 2, making the internal space of the toughening furnace wider so that the glass is not easily thermally scalded, and the quality of the glass product can be improved.

[0022] Preferably, the conveying roller 2 is made of ceramic, and the support 4 is made of ceramic. The support 4 is the support point between the heating radiation plate 5 and the heating tube. The support 4 and the heating radiation plate 5 play a heat insulation role to prevent the temperature of the heating tube in the furnace from directly irradiating the conveying roller 2.

[0023] As Figure 1 shown, air jet pipes 3 are arranged above and below the conveying roller 2.

[0024] Support rods are arranged in the furnace body. Each support 4 is installed at the upper end of a support rod. The lower end of the support rod is installed on the furnace body through a plurality of bolts. A through hole for the bolts to pass through is provided at the lower end of the support rod. The through hole is a waist-shaped hole, and threaded holes for the bolts to be inserted are provided on the furnace body. Each bolt passes through a through hole respectively. The length of the through hole provided at the lower end of the support rod is greater than the diameter of the bolt. The through hole is vertically arranged and is a waist-shaped hole, which is convenient for installation and facilitates adjusting the installation position of each support rod, and thus the height of the support 4 can be adjusted so that the heights of all supports 4 are easily kept consistent.

[0025] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
