A tooling jig for reinforcing a total length of a flue of a cover plate glass kiln

Abstract

The application discloses a tool jig for reinforcing a flue overall course of a cover plate glass kiln, which comprises connecting pieces and supporting pieces symmetrically arranged on both sides of a flue overall course support frame; one end of the connecting piece is fixed to the flue overall course support frame, and the other end is hung to the supporting piece; and one end of the supporting piece is arranged on a first spiral platform steel. Through the symmetrically arranged connecting pieces and supporting pieces, the tool jig can balance the tension on both sides of the flue overall course, and effectively avoid the problem of unstable operation caused by uneven unilateral stress. Meanwhile, through the connecting mode of the connecting pieces and the supporting pieces, when the steel structure slightly deforms, partial stress can be offset through the flexible buffering of the connecting pieces, so that the stability of the flue overall course is improved.

Description

Technical Field

[0001] This application belongs to the field of glass processing technology, and specifically relates to a tooling fixture for reinforcing the entire flue of a cover glass kiln. Background Technology

[0002] In the field of overflow-process high-alumina-silicon cover glass manufacturing, the furnace is one of the core pieces of equipment, and its operational stability directly affects product quality and production efficiency. The furnace operates for extended periods in a high-temperature environment (typically exceeding 1500℃), and the flue gas duct system, as a key component for discharging waste gas from the furnace, plays a crucial role in transporting the high-temperature waste gas (approximately 800℃ and above) to the flue gas treatment system. Simultaneously, the flue gas duct system must also ensure stable furnace pressure and collect falling particulate matter during waste gas emission.

[0003] However, existing methods for fixing the flue gas duct assembly have significant drawbacks. The flue gas duct assembly is typically supported at the bottom by a fixed bracket, and the upper part is fixed to the steel structure of the kiln's front wall with threaded nails, with the sides reinforced by welded fasteners. Due to long-term high-temperature operation, the steel structure and fixed brackets are prone to thermal deformation, causing the flue gas duct assembly to tilt. This tilt not only causes unstable flue gas emissions but also leads to red-hot leakage at the flue gas inlet, severely affecting kiln pressure control and product quality stability. Furthermore, the existing fixing method lacks dynamic adjustment capabilities and cannot adapt to deformation under high-temperature conditions, further exacerbating the instability of the flue gas duct assembly.

[0004] Currently, industry solutions mainly focus on periodic inspections and replacement of fixed components, but this not only increases maintenance costs but may also lead to production interruptions. Therefore, there is an urgent need for a simple, easy-to-use tooling fixture that can effectively reinforce the entire flue system to solve the above problems and ensure the long-term stable operation of the kiln. Utility Model Content

[0005] The purpose of this application is to provide a tooling fixture for reinforcing the entire flue of a covered glass furnace. This solves the technical problems mentioned in the background art, such as flue tilting, flue gas leakage, and unstable furnace pressure caused by high-temperature deformation, thus achieving dynamic reinforcement and long-term stable operation of the flue system.

[0006] To achieve the above objectives, this application adopts the following technical solution: A tooling fixture for reinforcing the flue of a covered glass kiln, characterized in that it includes connectors and supports symmetrically arranged on both sides of the flue support frame; One end of the connector is fixed to the flue gas duct support frame, and the other end is attached to the support. One end of the support component is mounted on the spiral platform steel structure.

[0007] In one possible implementation, the support member includes a first fixing member, a chain, and a second fixing member; The first fastener is used to secure the chain to the flue assembly support frame; The second fastener is used to secure the chain to the support frame.

[0008] In one possible implementation, the connector includes a steel pipe and a third fastener; The chain is fixed to the steel pipe by a second fastener, and one end of the steel pipe is fixed to the spiral platform steel structure by a third fastener.

[0009] In one possible implementation, the first fastener is configured as a fastening screw.

[0010] In one possible implementation, the second fastener is configured as a hook, the chain is hooked onto the hook, and the hook is integrally connected to the steel pipe.

[0011] In one possible implementation, the length of the chain is adjustable to accommodate the distance between the flue support frame and the steel pipe.

[0012] In one possible implementation, the third fastener is configured as an adjusting screw for securing the steel pipe to the spiral platform steel structure.

[0013] In one possible implementation, a high-temperature resistant gasket is provided between the steel pipe and the spiral platform steel structure.

[0014] In one possible implementation, both the chain and the steel pipe have been treated with an anti-oxidation coating.

[0015] In one possible implementation, the steel pipe is a hollow square structure with reinforcing ribs spaced apart along the axial direction inside. The reinforcing ribs are integrally formed with the inner wall of the steel pipe and have a thickness of 1.2-1.5 times the wall thickness of the steel pipe.

[0016] Compared with the prior art, this application has the following beneficial effects: This application provides a tooling fixture for reinforcing the entire flue of a covered glass furnace. Through symmetrically arranged connectors and supports, it can balance the tensile forces on both sides of the flue, effectively preventing tilting caused by uneven force on one side. Simultaneously, the connection method of the connectors and supports allows for the flexible buffering of the connectors to offset some of the stress when the steel structure undergoes slight deformation, thereby improving the stability of the entire flue.

[0017] In one possible implementation, the first and second fixing members facilitate fixing one end of the chain to the flue assembly support frame and the other end of the chain to the support member. By using the chain as a flexible support member, it can adapt to the slight displacement of the flue assembly under high temperature environment and avoid damage to components due to rigid connection.

[0018] In one possible implementation, using a fastening screw as the first fixing element offers high reliability, capable of withstanding the weight of the entire flue and the stress generated by thermal expansion and contraction. Simultaneously, the fastening screw connection facilitates subsequent adjustment of the chain tension, allowing for fine-tuning of the reinforcement force in real-time based on the deformation of the steel structure.

[0019] In one possible implementation, the one-piece molded hook structure offers high strength, avoiding the risk of breakage due to welding defects. The hook-and-loop connection facilitates chain installation, and during kiln operation, the chain can swing freely with slight swaying of the flue gas duct, thereby reducing stress concentration.

[0020] In one possible implementation, the adjustable-length chain can dynamically compensate for the deformation of the steel pipe and flue assembly support frame, always maintaining effective tension on the flue assembly support frame, avoiding chain slack or overload due to distance changes, significantly improving the adaptability of tooling fixtures to high-temperature environments, and reducing the number of maintenance operations due to structural failure.

[0021] In one possible implementation, high-temperature resistant gaskets can effectively isolate heat conduction between the steel pipe and the spiral platform steel structure, reducing the risk of deformation of the spiral platform steel structure due to localized overheating. Simultaneously, the elasticity of the gaskets can absorb some vibration energy, reducing the impact of vibrations generated during kiln operation on the fixed connections, thereby improving the stability of the connection.

[0022] In one possible implementation, the addition of reinforcing ribs significantly improves the bending strength and stiffness of the steel pipe, making it less prone to deformation when subjected to chain tension. The hollow structure reduces overall weight while maintaining strength, facilitating installation and disassembly, while the one-piece molding process avoids stress concentration problems that might arise from welding reinforcing ribs.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this application discloses a tooling fixture for reinforcing the flue gas duct of a cover glass furnace. The tooling fixture for reinforcing the flue gas duct of a cover glass furnace may include connectors and supports symmetrically installed on the left and right sides of the flue gas duct support frame 1.

[0032] The connector can be a stainless steel chain 3, and the support can be a square stainless steel tube 5.

[0033] The bottom of chain 3 is fixed to the flue support frame 1, the top of chain 3 is fixed to steel pipe 5, and one end of steel pipe 5 is fixed to spiral platform steel structure 7.

[0034] In this embodiment, the symmetrically arranged connectors and supports balance the tensile forces on both sides of the flue assembly, effectively preventing tilting caused by uneven force on one side. Furthermore, the connection method of the connectors and supports allows for the flexible buffering of the connectors to offset some stress when the steel structure undergoes slight deformation, thereby improving the stability of the flue assembly.

[0035] In one possible embodiment, the support member may include a first fixing member 2, a chain 3, and a second fixing member 4.

[0036] The bottom of the chain 3 is locked in the pre-set screw hole of the flue support frame 1 by the first fastener, and the top of the chain 3 is fixed to the support by the second fastener 4.

[0037] In this embodiment, the first fixing member 2 and the second fixing member 4 facilitate fixing one end of the chain 3 to the flue assembly support frame 1, and fixing the other end of the chain 3 to the support member. By using the chain 3 as a flexible support member, it can adapt to the slight displacement of the flue assembly under high temperature environment and avoid damage to the components due to rigid connection.

[0038] In one possible embodiment, the connector includes a steel pipe 5 and a third fastener 6. The chain 3 is fixed to the steel pipe 5 by a second fastener 4, and one end of the steel pipe 5 is fixed to the spiral platform steel structure 7 by the third fastener 6.

[0039] In one possible embodiment, the first fastener 2 is configured as a fastening screw.

[0040] The first fastener 2 is set with an M12 specification fastening screw, and a corresponding threaded hole is machined on the flue support frame 1. The lower end of the stainless steel chain 3 is locked in the threaded hole by a nut and a washer to ensure a firm connection.

[0041] In this embodiment, the connection method of setting the first fixing member 2 as a fastening screw has high reliability and can withstand the gravity of the entire flue and the stress generated by thermal expansion and contraction. At the same time, the fastening screw connection facilitates the adjustment of the tension of the chain 3 in the later stage, and the reinforcement force can be finely adjusted in real time according to the deformation of the steel structure.

[0042] In one possible embodiment, the second fastener 4 is configured as a hook, the chain 3 is hooked onto the hook, and the hook is integrally connected to the steel pipe 5.

[0043] The second fastener 4 is an L-shaped stainless steel hook welded to the lower left end of the steel pipe 5. The hook is connected to the steel pipe 5 by full welding. The upper part of the chain 3 is directly hooked onto the horizontal section of the hook, and the opening of the hook faces the side of the flue.

[0044] In this embodiment, the one-piece molded hook structure has high strength, avoiding the risk of breakage due to welding defects. The hook-on method makes the chain 3 easy to install. During kiln operation, the chain 3 can swing freely with the slight swaying of the flue, thereby reducing stress concentration.

[0045] In one possible embodiment, the length of the chain 3 is adjustable to accommodate the distance between the flue support frame 1 and the steel pipe 5.

[0046] The chain 3 is an adjustable length turnbuckle chain 3. The chain 3 has a turnbuckle assembly in the middle. The total length of the chain 3 can be adjusted by rotating the bolt to adapt to the distance change between the flue support frame 1 and the steel pipe 5 caused by thermal deformation.

[0047] In this embodiment, the adjustable-length chain 3 can dynamically compensate for the deformation of the steel pipe 5 and the flue support frame 1, and always maintain an effective tension on the flue support frame 1, avoiding the chain 3 from becoming loose or overloaded due to changes in distance. This significantly improves the adaptability of the tooling fixture to high-temperature environments and reduces the number of maintenance operations due to structural failure.

[0048] In one possible embodiment, the third fastener is configured as an adjusting screw for securing the steel pipe 5 to the spiral platform steel structure 7.

[0049] The third fixing part 6 is set as an adjusting screw. An elongated adjusting hole is opened on the spiral platform steel structure 7. The right end of the steel pipe 5 is fixed in the elongated hole by the adjusting screw. The steel pipe 5 can be moved left and right along the elongated hole by loosening the screw. After adjusting to the appropriate position, it is tightened to fix it.

[0050] In this embodiment, the third fixing member 6 is set as an adjusting screw, which facilitates fine adjustment of the steel pipe 5 in the horizontal direction and can adapt to positional deviations under different installation conditions. At the same time, the installation angle of the steel pipe 5 can be precisely adjusted according to the actual inclination of the flue, thereby optimizing the reinforcement effect.

[0051] In one possible embodiment, a high-temperature resistant gasket is provided between the steel pipe 5 and the spiral platform steel structure 7.

[0052] Optionally, a high-temperature resistant gasket made of ceramic fiber is installed at the connection between the steel pipe 5 and the spiral platform steel structure 7. The gasket is 3mm thick and its surface is coated with a high-temperature resistant adhesive to prevent the gasket from shifting in a high-temperature environment.

[0053] In this embodiment, the high-temperature resistant gasket effectively isolates the heat conduction between the steel pipe 5 and the spiral platform steel structure 7, reducing the risk of deformation of the spiral platform steel structure 7 due to local overheating. Simultaneously, the elasticity of the gasket absorbs some vibration energy, reducing the impact of vibrations generated during kiln operation on the fixed connection, thereby improving the stability of the connection.

[0054] In one possible embodiment, both the chain 3 and the steel pipe 5 have been treated with an anti-oxidation coating.

[0055] Both the chain 3 and the steel pipe 5 were chrome-plated for anti-oxidation treatment, which can effectively resist the corrosion of metal parts by corrosive gases in high-temperature flue gas.

[0056] In the embodiments of this application, the anti-oxidation treatment significantly extends the service life of tooling and fixtures, and reduces reinforcement failure caused by component corrosion. In the long-term high-temperature and highly corrosive environment of the kiln, it can reduce the maintenance frequency and ensure the continuous and stable operation of the kiln.

[0057] In one possible embodiment, the steel pipe 5 is a hollow square structure with reinforcing ribs spaced apart along the axial direction inside. The reinforcing ribs are integrally formed with the inner wall of the steel pipe 5 and have a thickness of 1.2-1.5 times the wall thickness of the steel pipe 5.

[0058] The steel pipe 5 is designed as a hollow square structure, with a cross-shaped reinforcing rib set every 200mm along the axial direction inside. The reinforcing rib and the inner wall of the steel pipe 5 are integrally formed, and the thickness of the reinforcing rib is 1.2 times the wall thickness of the steel pipe 5.

[0059] In this embodiment, the addition of reinforcing ribs significantly improves the bending strength and stiffness of the steel pipe 5, making it less prone to deformation when subjected to the tension of the chain 3. The hollow structure reduces the overall weight while ensuring strength, facilitating installation and disassembly, while the one-piece molding process avoids stress concentration problems that may be caused by welding the reinforcing ribs.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
