Description

Technical Field

[0001] This utility model belongs to the technical field of tempered glass production equipment, specifically relating to a modular high-temperature resistant and deformation-resistant tempered glass furnace door structure, which can effectively improve the stability and reliability of the tempered furnace door under high-temperature conditions, while also being practical and easy to maintain. Background Technology

[0002] In glass tempering production, the tempering furnace door is a core component that determines production efficiency, product quality, and safety. It must remain sealed during heating and heat preservation, maintaining a stable high-temperature environment of approximately 700°C. Simultaneously, the opening must be precisely controlled during glass feeding and unloading, and dynamically adjusted according to the glass thickness. In the event of sudden events such as glass shattering inside the furnace, it must be quickly opened to prevent blockage. Frequent opening and closing (dozens of times per day) and prolonged high temperatures (around 700°C) subject it to high dynamic loads and thermal stress impacts, placing extremely high demands on its structural strength, thermal insulation, and fatigue resistance.

[0003] Currently, the mainstream frame-type tempering furnace doors in the industry face technical bottlenecks. For example, three tempering furnaces relocated and upgraded in an old factory developed unevenness and deformation in their doors only six months after commissioning, leading to poor closure. Inspection revealed that the original furnace doors had warped and deformed due to high-temperature creep, exposing the internal insulation layer to the high-temperature environment without effective protection. Combined with the fragile nature of the material, this resulted in damage and breakage of the insulation layer. Even after repairing the deformed frame and re-laying the insulation layer, structural failures repeatedly occurred, severely impacting yield and equipment stability. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a modular high-temperature resistant and deformation-resistant tempered glass furnace door structure. This structure features a modular design with differentiated thicknesses on the four sides of the tempered furnace door frame, multiple intermediate furnace door components installed within the frame, and aluminum silicate ceramic fiber bricks embedded within these components. The assembly of the furnace door frame, intermediate furnace door components, and aluminum silicate ceramic fiber bricks is designed with pre-reserved gaps. The furnace door frame and intermediate furnace door components are made of 201 stainless steel, and aluminum silicate ceramic fiber bricks are selected as the insulation layer. This design ensures that the furnace door will not deform or become uneven at high temperatures. This modular design offers advantages such as resistance to high-temperature deformation, corrosion resistance, durability, good insulation, and time-saving and labor-saving maintenance.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A modular high-temperature resistant and deformation-resistant glass tempering furnace door structure includes a furnace door frame 8. The furnace door frame 8 is a hollow cuboid structure with openings on the front side 8.7 and the bottom side 8.11 of the frame. Multiple furnace door intermediate components 7 are sequentially installed on the front side 8.7 of the furnace door frame 8. Connecting components 8.5 are provided at both ends of the top surface 8.6 of the furnace door frame 8 for suspending the furnace door at the top of the tempering furnace outlet. Guide mechanisms 13 are installed on the first frame side 8.8 and the second frame side 8.9 of the furnace door frame 8 for connecting with the slot devices on both sides of the tempering furnace outlet.

[0006] The furnace door intermediate component 7 is a hollow cuboid structure with an opening on the back side 7.4. The front side 7.3 of the furnace door intermediate component 7 faces outward and is fitted inside the furnace door frame 8. The top surface 7.5 of the furnace door intermediate component 7 is attached to the top surface 8.6 of the furnace door frame 8 and connected by a third screw 6. The first side 7.7 of the furnace door intermediate component 7 is attached to the first side 8.8 of the furnace door frame 8, the second side 7.8 of the furnace door intermediate component 7 is attached to the second side 8.9 of the furnace door frame 8, and the back side 7.4 of the second side 8.9 is attached to the furnace door frame. A first expansion gap 11 is reserved between the back side 8.10 of the frame 8; multiple furnace door intermediate components 7 are provided, and a second expansion gap 12 is reserved between the furnace door intermediate components 7. Multiple buckles 7.2 are vertically arranged on the side of the front side 7.3 of each furnace door intermediate component 7, which are used to connect adjacent furnace door intermediate components 7 and one end face of the front side 8.7 of the frame of the furnace door frame 8. A buckle 2 is provided on the other end face of the front side 8.7 of the frame of the furnace door frame 8. The other end face of the front side 8.7 of the frame of the furnace door frame 8 is connected to the side of the furnace door intermediate component 7 without buckles 7.2 through the buckle 2.

[0007] The connecting component 8.5 is located between two sets of frame threaded holes 8.3 at both ends of the top surface 8.6 of the furnace door frame 8. The connecting component 8.5 is a cuboid structure with holes 8.2 on it. The holes 8.2 are connected to the chain pins of the chain and are used to suspend the furnace door at the top of the tempering furnace outlet.

[0008] The guide mechanism 13 includes first threaded holes 8.1 on both the first frame side 8.8 and the second frame side 8.9 of the furnace door frame 8, for screwing in and fixing the matching first screw 10, and locking it with a nut 1.

[0009] The top surface 8.6 of the furnace door frame 8 has multiple sets of frame threaded holes 8.3, with two frame threaded holes 8.3 forming a set; the top surface 7.5 of each furnace door intermediate component 7 is provided with a set of component threaded holes 7.1, with two component threaded holes 7.1 forming a set. Each set of component threaded holes 7.1 corresponds to any set of frame threaded holes 8.3 and is connected by a third screw 6. The number of furnace door intermediate components 7 is the same as the number of sets of frame threaded holes 8.3.

[0010] The diameter of the threaded hole 8.3 in the frame is larger than the diameter of the threaded hole 7.1 in the component.

[0011] The third screw 6 is connected to the frame threaded hole 8.3 in sequence through the spring washer 5 and the flat washer 4.

[0012] The hollow part of the furnace door intermediate component 7 is provided with aluminum silicate ceramic fiber brick 9, and a third expansion gap 7.6 is reserved between it and the furnace door intermediate component 7. The aluminum silicate ceramic fiber brick 9 has a rectangular shape and is used for the thermal insulation of the furnace door.

[0013] The top surface 8.6 of the furnace door frame 8 has a thickness of 9-11mm, the side surfaces 8.8 and 8.9 of the first frame have a thickness of 6-8mm, and the back surface 8.10 of the frame has a thickness of 2-4mm.

[0014] The end face of the second frame side 8.9 of the furnace door frame 8 is provided with a second threaded hole 8.4. The buckle 2 is connected to the threaded hole 8.4. The buckle hole 2.1 and the threaded hole 8.4 on the buckle 2 are aligned concentrically and connected by the matching second screw 3. The buckle 2 is connected to the side of the furnace door middle component 7 without the buckle 7.2 by the second screw 3.

[0015] The furnace door frame 8 and the furnace door intermediate component 7 are made of 201 stainless steel for corrosion resistance.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the differentiated thickness design of the top surface 8.6, the first side surface 8.8, the second side surface 8.9, and the back surface 8.10 of the furnace door frame 8, can reduce the weight of the furnace door frame 8, while ensuring that the top surface 8.6 (the main load-bearing surface: bearing the weight of the furnace door intermediate component 7, the aluminosilicate ceramic fiber brick 9, and the tension of the chain connection) has sufficient bending strength, so that the furnace door frame 8 will not deform in the high temperature environment of the tempering furnace.

[0017] 2. This utility model reserves a third expansion gap 7.6 between the furnace door intermediate component 7 and the aluminosilicate ceramic fiber brick 9, and a second expansion gap 12 between the furnace door intermediate components 7 and 7. The connection between the furnace door intermediate component 7 and the furnace door frame 8 is achieved by reserving an expansion gap between the component threaded hole 7.1 and the frame threaded hole 8.3. That is, the diameter of the frame threaded hole 8.3 is larger than the diameter of the component threaded hole 7.1. This eliminates the problem of deformation of the furnace door frame or damage to the internal components of the furnace door frame caused by mutual compression during thermal expansion of the various components inside the furnace door.

[0018] 3. By setting a buckle 7.2 on the furnace door middle component 7, this utility model can realize the interconnection between the furnace door middle components 7, making the connection between the furnace door middle components 7 more secure, and can prevent the phenomenon that the furnace door middle component 7 will fall off the furnace door frame 8 if the connection between a single furnace door middle component 7 and the furnace door frame 8 is not secure.

[0019] 4. The furnace door of this utility model uses aluminum silicate ceramic fiber bricks for internal insulation, which can reduce the weight of the furnace door while ensuring the insulation effect.

[0020] 5. The furnace door frame 8 and the furnace door intermediate component 7 of this utility model are made of 201 stainless steel, which prevents the surface of each part of the furnace door from rusting and keeps the furnace door looking beautiful.

[0021] 6. The design of the multiple furnace door intermediate components 7 of this utility model adopts completely uniform external dimensions and installation position dimensions, so that each component can be disassembled and assembled independently, can be quickly installed and disassembled, and is interchangeable, making maintenance convenient.

[0022] In summary, through the above-mentioned innovations, this utility model enables the furnace door to possess the advantages of self-supporting load-bearing capacity and resistance to deformation, resistance to deformation under heat, good heat preservation effect, and an attractive appearance. Most importantly, compared with traditional furnace doors, its overall resistance to deformation has been significantly improved. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a modular high-temperature resistant and deformation-resistant tempered glass furnace door structure includes: two "M12 external hexagonal nuts 1", two "clips 2", two "M4X20 cylindrical head internal hexagonal second screws 3", eight "M8 flat washers 4", eight "M8 spring washers 5", eight "M8X20 cylindrical head internal hexagonal third screws 6", four "furnace door intermediate components 7", one "furnace door frame 8", four "aluminosilicate ceramic fiber bricks 9", and two "M12x40 first screws 10".

[0031] like Figure 1 , Figure 2 As shown, the furnace door frame 8 is a hollow cuboid structure with openings on the front side 8.7 and the bottom side 8.11. Multiple furnace door intermediate components 7 are sequentially installed on the front side 8.7 of the furnace door frame 8. Connecting components 8.5 are provided at both ends of the top surface 8.6 of the furnace door frame 8 for suspending the furnace door frame 8 so that it can drive the furnace door to move up and down as a whole. The first frame side 8.8 and the second frame side 8.9 of the furnace door frame 8 are respectively provided with first threaded holes 8.1 for installing M12. The first screw 10 of M12x40 is installed in the first threaded hole 8.1 of M12 and locked with an M12 hexagonal nut 1. Then, the screw part of the first screw 10 of M12x40 is connected to the rectangular slot device on both sides of the tempering furnace outlet. The screw is inserted into the slot and moves up and down in the slot. Through the connection between the screw and the slot, the horizontal swing of the furnace door is restricted during the up and down movement of the furnace door, making the furnace door more stable.

[0032] The furnace door frame 8 has a differentiated thickness design for its top surface 8.6, first frame side 8.8, second frame side 8.9, and frame back surface 8.10. The thickness of the top surface 8.6 of the furnace door frame 8 is 9-11mm, preferably 10mm; the thickness of the first frame side 8.8 and the second frame side 8.9 is 6-8mm, preferably 7mm; and the thickness of the frame back surface 8.10 is 2-4mm, preferably 3mm.

[0033] The top surface 8.6 of the furnace door frame 8 has eight φ9 frame threaded holes 8.3 arranged from left to right. The eight φ9 frame threaded holes 8.3 are numbered 1, 2, 3, 4, 5, 6, 7, and 8 from left to right, and are divided into four groups of frame threaded holes 8.3: 1 and 2 are the first group, 3 and 4 are the second group, 5 and 6 are the third group, and 7 and 8 are the fourth group.

[0034] A connecting component 8.5 is provided between the two sets of frame threaded holes 8.3 at both ends of the top surface 8.6 of the furnace door frame 8. The connecting component 8.5 is a cuboid structure with a φ6 hole 8.2 on it. The φ6 hole 8.2 is connected to the chain pin and is used to suspend the furnace door at the top of the tempering furnace outlet. The motor fixed to the top of the tempering furnace drives the sprocket, which drives the chain to move, realizing the conversion of rotational motion into linear (up and down) motion, thereby realizing the up and down movement of the furnace door. As the motor rotates forward and backward, the chain moves up and down. When the chain moves to the lowest position (lower limit), the furnace door is in the closed state. When the chain rises, the furnace door gradually opens. When the chain moves to the highest position (upper limit), the furnace door is in the maximum open state.

[0035] like Figure 2 As shown, the end face of the second frame side 8.9 of the furnace door frame 8 is provided with an M4 second threaded hole 8.4. The buckle 2 is connected to the threaded hole 8.4. The buckle hole 2.1 and the threaded hole 8.4 on the buckle 2 are concentrically aligned and connected by the matching M4 second screw 3. The M4 second screw 3 is screwed into and fixed to the M4 second threaded hole 8.4, but does not need to be tightened. The buckle 2 is rotated around the buckle hole 2.1. When it reaches a certain angle and can be locked to the left side of the furnace door middle component 7, the M4 second screw 3 is tightened to achieve the locking function.

[0036] like Figure 1 The M8 flat washer 4, M8 spring washer 5, and M8 third screw 6 are shown. The M8 flat washer 4 and M8 spring washer 5 are both annular washers, and the M8 third screw 6 is a cylindrical screw. The M8 flat washer 4 and M8 spring washer 5 are passed through the M8 third screw 6, with the M8 spring washer 5 being passed through first and then the M8 flat washer 4. The M8 flat washer 4, M8 spring washer 5, and M8 third screw 6 are used as a whole. The furnace door middle component 7 and the furnace door frame 8 are fixed together by passing through the frame threaded hole 8.3 with 8 sets of M8 flat washer 4, M8 spring washer 5 and M8 third screw 6, and then screwing them into the component threaded hole 7.1 until the M8 third screw 6 is tightened together with the frame threaded hole 8.3 and the component threaded hole 7.1.

[0037] like Figure 3As shown, the furnace door intermediate component 7 is a hollow cuboid structure with an opening on the back 7.4. The front 7.3 of the furnace door intermediate component 7 faces outward and is fitted inside the furnace door frame 8. The top surface 7.5 of the furnace door intermediate component 7 is attached to the top surface 8.6 of the frame of the furnace door frame 8 and connected by the third screw 6 of M8. There are multiple (4) furnace door intermediate components 7. The external dimensions and installation dimensions of the multiple furnace door intermediate components 7 are exactly the same. A second expansion gap 12 is reserved between the furnace door intermediate components 7. Multiple (4) buckles 7.2 are vertically arranged on the side of the front 7.3 of each furnace door intermediate component 7 to connect the adjacent furnace door intermediate components 7 and one end face of the frame front 8.7 of the furnace door frame 8. Two buckles 2 are provided on the other end face of the frame front 8.7 of the furnace door frame 8. The other end face of the frame front 8.7 of the furnace door frame 8 is connected to the side of the furnace door intermediate component 7 without buckles 7.2 by the two buckles 2.

[0038] The top surface 7.5 of the furnace door intermediate component 7 is provided with two M8 component threaded holes 7.1. Each furnace door intermediate component 7 has two M8 component threaded holes 7.1 that can be connected and fixed to any of the aforementioned set of φ9 frame threaded holes 8.3. Each set of four furnace door intermediate components 7 has two M8 component threaded holes 7.1 connected to the aforementioned four sets of φ9 frame threaded holes 8.3, with corresponding installation dimensions, and connected via an M8 third screw 6. The back surface 7.4 of the furnace door intermediate component 7 is installed opposite to the front surface 8.7 of the furnace door frame 8. Four latches 7.2 are provided on the far right side of the front surface 7.3 of the furnace door intermediate component 7. Their function is to allow the left furnace door intermediate component 7 to press onto the right furnace door intermediate component 7, making the furnace door intermediate component 7 more securely fixed.

[0039] The diameter of the threaded hole 8.3 in the frame is larger than the diameter of the threaded hole 7.1 in the component, resulting in a certain gap when they are locked together.

[0040] like Figure 4 , Figure 6 As shown, an aluminum silicate ceramic fiber brick 9 is provided in the hollow position of the furnace door intermediate component 7. The aluminum silicate ceramic fiber brick 9 has a cuboid shape and is inserted into the interior of the furnace door intermediate component 7 through the back side 7.4 of the component and a third expansion gap 7.6 is reserved.

[0041] This utility model uses aluminum silicate ceramic fiber bricks 9 with a density of 400Kg / m³ and a single brick weighing approximately 2KG to enhance heat insulation.

[0042] Aluminosilicate ceramic fiber bricks have the same external dimensions.

[0043] like Figure 5As shown, the buckle 2 is a small cube structure with a φ5.5 buckle hole 2.1, which is used to lock the leftmost furnace door middle component 7. The second screw 3 of M4 passes through the buckle 2.1 and is screwed into the threaded hole 8.4 to connect and press the left side of the furnace door middle component 7.

[0044] The second screw 3 of M4 is an M4X20 cylindrical head hexagonal screw, which locks the leftmost furnace door middle component 7 through the second threaded hole 8.4 of M4 on the left side of the furnace door frame 8 via the clip 2.

[0045] The specific installation method of this utility model is as follows: First, arrange the furnace door frame 8, furnace door intermediate component 7, and aluminosilicate ceramic fiber bricks 9. Then, install the aluminosilicate ceramic fiber bricks 9 in the space of the furnace door intermediate component 7. Next, place four furnace door intermediate components 7 containing aluminosilicate ceramic fiber bricks 9 into the furnace door frame 8 in order from right to left, with the unfaced sides of the two components facing each other. The installation dimensions of the two M8 component threaded holes 7.1 on the top of each furnace door intermediate component 7 correspond to the four sets of φ9 frame threaded holes 8.3 on the furnace door frame 8. Align the M8 component threaded hole 7.1 and the φ9 frame threaded hole 8.3, ensuring they are concentric. Then, screw the eight M8X20 cylindrical head hexagonal screws 6 into the frame threaded holes 8.3 and component threaded holes 7.1 on the top surface 8.6 of the furnace door frame 8 from right to left until the screws are tightened. This installs the four furnace door intermediate components 7 containing aluminosilicate ceramic fiber bricks 9 onto the furnace door frame 8. Each furnace door intermediate component 7 has a latch 7.2 on its right side (e.g., ...). Figure 3 (As shown) is used to press the left side of the adjacent right-side furnace door intermediate assembly 7, so the left-side furnace door intermediate assembly 7 can press the right-side furnace door intermediate assembly 7. Finally, the buckle 2 and its "M4X20 cylindrical head internal hexagon second screw 3" are used to lock the leftmost furnace door intermediate assembly 7.

[0046] 2. Insert the M12 hexagonal nut 1 into the M12x40 first screw 10, then install the two M12x40 first screws 10 into the M12 first threaded holes 8.1 on the left and right sides of the furnace door frame 8, and tighten them with the "M12 hexagonal nut 1". The first screw 10 of the M12x40 type serves as a guide during the lifting and lowering of the furnace door. The screw of the first screw 10 connects to the rectangular slots on both sides of the tempering furnace outlet. A small gap exists between the screw of the first screw 10 and the rectangular slots on both sides of the tempering furnace outlet. This gap allows for fine-tuning of the screw within a certain range while limiting the horizontal displacement of the furnace door during lifting and lowering. When the furnace door moves up and down driven by the chain and sprocket, the first screw 10 of the M12x40 moves along a specific guide path, ensuring that the furnace door remains firmly against the tempering furnace. This ensures a smooth and precise lifting and lowering process, effectively preventing problems such as poor sealing and heat loss caused by shaking, thus improving the working efficiency of the tempering furnace and the quality of the tempered products.

[0047] 3. The function of the two connecting components 8.5 welded to the left and right ends of the top surface 8.6 of the furnace door frame 8: The connecting components 8.5 welded to the left and right ends of the top surface 8.6 of the furnace door frame 8 are used to suspend the furnace door frame 8. A φ6 hole 8.2 is drilled in the middle. Its function is to connect with the chain pin of the chain through the φ6 hole 8.2, thereby realizing the mechanical connection between the furnace door and the chain.

[0048] 4. Working principle of the furnace door movement system The motor is equipped with two sprockets via a drive shaft, which rotate the sprockets. The two sprockets mesh with two chains. Since the two chains are connected to the connecting components 8.5 at both ends of the top surface 8.6 of the furnace door frame 8, the rotation of the sprockets drives the chains to reciprocate up and down, thereby opening and closing the furnace door. This transmission method can precisely control the position of the furnace door, meeting the automation requirements for opening and closing the furnace door during production, and ensuring the sealing and stability of the tempering furnace during operation.

[0049] 5. This utility model has the following six main features: (1) Materials: The furnace door frame 8 and the furnace door intermediate component 7 are made of 201 stainless steel for corrosion protection; (2) The furnace door frame 8 is a hollow cuboid structure with openings on the front 8.7 and bottom 8.11 of the frame, and is not directly heated; (3) The furnace door intermediate component 7 is a hollow cuboid structure with openings on the front 7.3 and bottom, and has a certain gap with the aluminum silicate ceramic fiber brick 9 embedded inside, so the front 7.3 of the furnace door intermediate component 7 is directly heated; (4) Assembly: A first expansion gap 11 is reserved between the furnace door intermediate component 7 and the furnace door frame 8, and the top threaded hole has a certain gap to release heat stress, so the furnace door intermediate component 7 is directly heated and can prevent the furnace door frame from being directly heated and deformed; (5) Advantages: Modular and easy to install and disassemble, gap prevents deformation, fiber brick insulation and lightweight; (6) Effect: No deformation after use, good insulation and low energy consumption.

[0050] The working principle of this utility model is as follows: The motor mounts two sprockets via a drive shaft, driving them to rotate. Each sprocket meshes with one of two chains. One end of each chain is fixed to one of the sprockets, and the other end is fixed to the connecting components 8.5 at both ends of the top surface 8.6 of the furnace door frame 8. The rotation of the sprockets drives the chains to reciprocate up and down, thus opening and closing the furnace door. This transmission method allows for precise control of the furnace door position, meeting the automation requirements for furnace door opening and closing during production, and ensuring the sealing and stability of the tempering furnace during operation. When the chain is at its lowest position, the furnace door is closed, achieving heat preservation at the tempering furnace outlet; when the chain is at its highest position, the furnace door is fully open.
