Description

Technical Field

[0001] This utility model relates to a flame-blocking brick used in the production of photovoltaic rolled glass, and a flame-blocking device for the feeding port of a rolled glass melting furnace using the flame-blocking brick. Background Technology

[0002] In the production of rolled glass, flame-blocking bricks and adjustable, horizontally movable flame-blocking devices are used to prevent hot air from escaping from the kiln and reduce heat loss. For example, the flame-blocking brick and its device previously developed by the applicant, see CN222274365U "A Flame-Blocking Brick and Flame-Blocking Device for Rolled Glass Overflow Port", can reduce heat loss and achieve energy-saving effects. However, during the production process, there are still problems such as flying material easily accumulating and being inconvenient to clean, and suspended tools being damaged by the flames. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flame-blocking brick, which solves the above-mentioned problem through a specific shape design, and at the same time provides a flame-blocking device using the flame-blocking brick.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flame-blocking brick, the flame-blocking brick being trapezoidal in shape, consisting of vertically distributed end faces on the left and right sides, a top surface and a bottom surface distributed horizontally, a rear end face distributed vertically on the rear side, and a front end face with a slope on the front side; the rear end face is directed towards the inside of the melting furnace, and the slope of the front end face is directed towards the outside of the melting furnace, the slope being inclined from top to bottom outwards; a groove is formed on the top surface for assembly with a suspension tool for suspending the flame-blocking brick.

[0005] The terms "vertical distribution" and "horizontal distribution" refer to an overall approximate vertical and horizontal orientation that meets functional requirements, without requiring absolute verticality or horizontality. The melting furnace is existing equipment involved in production practice and will not be elaborated upon here. The phrase "with a slope on the front face" means that the front face can be a single sloped surface or a partially sloped and partially vertical surface. Therefore, the meaning of "trapezoidal" is not limited to a geometric shape with only four sides; it can be a trapezoid with a four-sided vertical cross-section or a trapezoid with five sides (two corresponding sides on the front face), such as... Figure 1 As shown.

[0006] Preferably, the groove has an inverted T-shaped vertical cross-section that extends through the left and right vertical end faces of the flame-blocking brick, and is used to assemble with an I-shaped lifting device as a suspension tool so that the lifting device can be slidably installed into the groove.

[0007] A flame-blocking device for the feeding port of a rolling glass melting furnace includes an I-shaped hanger and flame-blocking bricks as described above; multiple flame-blocking bricks are slidably assembled with the I-shaped hanger via grooves and suspended side by side on the same hanger.

[0008] The advantages of this utility model compared with the prior art are as follows: The flame-blocking brick provided by this utility model has a specific trapezoidal structure formed by vertically distributed end faces, horizontally distributed top and bottom faces, a vertical rear face, and a sloping front face. The vertical face of the rear face facing the inside of the melting furnace is beneficial to the sealing of the connection between the feeding port and the melting furnace. The sloping shape of the front face facing the outside of the melting furnace makes it difficult for flying material to accumulate and easy to clean. The groove designed on the top face allows the mounting part of the suspended tool to be hidden inside the brick body, reducing direct scorching of the flame and protecting the tool.

[0009] Figure 1 This is a schematic diagram of the vertical cross-section structure of the flame-blocking brick of this utility model;

[0010] Figure 2 This is a schematic diagram of the flame-blocking device of this utility model.

[0011] The numbers in the diagram are: 1-flame baffle brick, 11-vertical end face, 12-top face, 121-groove, 13-bottom face, 14-rear end face, 15-front end face, 151-slope, 152-vertical face, 2-lifting device. Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] Reference Figure 1 and Figure 2 As can be seen, the flame-blocking brick 1 provided in this embodiment has a trapezoidal shape with five sides in its vertical cross-section. It is formed by vertical end faces 11 distributed vertically on the left and right sides, a top face 12 and a bottom face 13 distributed horizontally, a rear end face 14 distributed vertically on the rear side, and a front end face 15 with a slope 151 on the front side. The front end face 15 has a slope 151 and a vertical face 152. Of course, in other embodiments, the front end face can also be designed as a complete slope surface, so that it presents a trapezoidal shape with four sides.

[0014] The rear end face of the flame deflector brick 1 faces the inside of the melting furnace, and its vertical shape facilitates sealing at the junction of the feed inlet and the melting furnace. The slope 151 of the front end face 15 of the flame deflector brick 1 faces the outside of the melting furnace, and the slope 151 slopes outward from top to bottom, making it difficult for flying material to accumulate and easy to clean. The left and right vertical end faces 11 ensure a tight fit between the side-by-side bricks. This flame deflector brick is made of sintered zircon-mullite refractory brick, and its relatively thick body provides good insulation for the feed inlet.

[0015] The top surface 12 has a groove 121 for assembling with a suspension tool for suspending the flame-blocking brick 1. Specifically, the groove 121 has an inverted T-shaped vertical cross section and penetrates the two vertical end faces 11 on the left and right sides of the flame-blocking brick 1. It is used to assemble with the I-shaped lifting device 2, which serves as a suspension tool, so that the lifting device 2 can be slidably installed into the groove 121.

[0016] This embodiment also provides a flame-blocking device at the feeding port of a rolling glass melting furnace, including an I-shaped hanger 2 and the aforementioned flame-blocking bricks 1; multiple flame-blocking bricks 1 are slidably assembled with the I-shaped hanger 2 via grooves 121 and suspended side-by-side on the same hanger 2. In operation, the upper part of the flame-blocking brick 1 is in close contact with the hanger 2, thereby preventing direct contact between the hanger 2 and the flame space. If a single flame-blocking brick is damaged by high temperature and flying material, the broken brick can be directly removed and replaced with a new one.

[0017] The lifting and lateral movement scheme of the aforementioned flame deflector can be implemented using existing suspension systems. The lifting equipment is installed within the suspension system, such as the "track, moving beam, hoist slings, suspension beam, and lifting rod" disclosed in CN222274365U in the background art. The structure and principle of the suspension system are existing technical knowledge and not innovative; therefore, they will not be detailed here.
