Description

Technical Field

[0001] This utility model relates to the field of coke removal technology for pool furnaces, specifically to an air barrier device for coke removal operations in large-capacity pool furnaces. Background Technology

[0002] In the research and development and manufacturing process of substrate glass, to ensure the zero-defect quality requirement of substrate glass, it is necessary to ensure that the glass substrate is large, thin, flat, transparent, tough, constant, pure and strong. "Purity" requires ensuring that the substrate glass is flawless in order to display its brilliance.

[0003] In the production process of substrate glass, large-capacity furnaces require a descaling operation once a month. Each large-capacity furnace has two feeding ports, one on the left and one on the right, and both descaling ports require descaling. However, during the descaling operation, due to the entry of outside air, the molten glass in the large-capacity furnace becomes contaminated by outside air and airborne particles, affecting the quality of the substrate glass. The number of substrate glass affected each month is approximately 170 pieces, which translates to more than 2,000 pieces of substrate glass being affected annually, significantly impacting the quality and sales volume of substrate glass. Utility Model Content

[0004] The purpose of this invention is to provide an air barrier device for large-capacity tank furnace coking operations to overcome the problems existing in the prior art. This invention can ensure the purity and flawlessness of the substrate glass, ensure the stability of the substrate glass quality, and greatly improve the quality of the product.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An air barrier device for coke removal operation of a large-capacity pool furnace includes a coke removal baffle, a coke removal baffle bracket installed on one side of the coke removal baffle, and a telescopic rod installed on the side of the coke removal baffle bracket away from the coke removal baffle.

[0007] Furthermore, the scorch clearing baffle bracket includes a first scorch clearing baffle bracket, a second scorch clearing baffle bracket, a third scorch clearing baffle bracket and a fourth scorch clearing baffle bracket. One end of each of the first scorch clearing baffle bracket, the second scorch clearing baffle bracket, the third scorch clearing baffle bracket and the fourth scorch clearing baffle bracket is connected to a support point, and the other end is connected to one side of the scorch clearing baffle respectively.

[0008] Furthermore, the telescopic rod is connected to the first scorch clearing baffle bracket, the second scorch clearing baffle bracket, the third scorch clearing baffle bracket, and the fourth scorch clearing baffle bracket via support points;

[0009] Furthermore, the descaling baffle is a rectangular baffle;

[0010] Furthermore, the four corners of the descaling baffle are equipped with reinforcing brackets;

[0011] Furthermore, the reinforcing bracket is a metal bracket;

[0012] Furthermore, the descaling baffle is a rectangular baffle;

[0013] Furthermore, the length of the descaling baffle is 50 cm and the width is 35 cm;

[0014] Furthermore, the end of the telescopic rod away from the coke removal baffle bracket is connected to a feeding device;

[0015] Furthermore, the telescopic rod is 75 cm long.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] This invention provides an air barrier device for descaling operations in large-capacity tank furnaces. The descaling baffle, as a component directly in contact with the high-temperature furnace body, completely covers the area to be descaled, forming a physical barrier and effectively preventing external air from entering the furnace. The telescopic rod, by adjusting its length, allows the descaling baffle to adapt to tank furnaces of different sizes and shapes, meeting diverse descaling needs. Operators can adjust the baffle position according to the furnace structure to ensure complete coverage of the descaling area. The descaling baffle bracket, as a component connecting the baffle and the telescopic rod, can withstand mechanical and thermal stresses under high-temperature conditions. This device effectively blocks the entry of external air, preventing the molten glass in the large-capacity tank furnace from being contaminated by outside air and airborne particles, ensuring the quality of the substrate glass and significantly reducing the possibility of producing defective substrate glass.

[0018] Furthermore, the four supports are evenly connected to the support point and the coke clearing baffle from different directions, forming a stable quadrilateral support system; the multi-point support effectively disperses the mechanical stress and thermal stress under high temperature environment, preventing the coke clearing baffle from deforming due to excessive local stress.

[0019] Furthermore, the four right-angled sides and regular planes of the rectangular baffle allow it to fit more closely to the furnace wall, forming a more airtight barrier.

[0020] Furthermore, the reinforced supports at the four corners form multi-point support, effectively dispersing mechanical and thermal stresses under high-temperature conditions and preventing the coking baffle from twisting or collapsing due to excessive local stress.

[0021] Furthermore, metal supports (such as stainless steel, nickel-based alloys, and high-temperature alloy steel) have excellent resistance to high-temperature oxidation and corrosion, and can operate stably for a long time under extreme working conditions of 800℃~1200℃.

[0022] Furthermore, the aspect ratio of the rectangular baffle allows it to more efficiently cover the narrow areas of the furnace (such as the furnace chamber and flue), and the straight edges of the rectangular baffle are more likely to fit tightly against the furnace wall, forming a continuous air barrier.

[0033] The coke removal baffle bracket 2 is installed on one side of the coke removal baffle 1. The coke removal baffle 1 is a rectangular baffle. The four right angles and regular planes of the rectangular baffle allow it to fit more closely to the furnace wall, forming a tighter air barrier. Reinforcing brackets are installed at the four corners of the coke removal baffle 1, forming multi-point support, effectively dispersing mechanical and thermal stresses under high-temperature conditions, and preventing the coke removal baffle 1 from twisting or collapsing due to excessive local stress.
