Description

Technical Field

[0001] This utility model belongs to the field of observation windows for glass annealing furnaces. Specifically, this utility model relates to a self-closing fan observation window structure for glass annealing furnaces. Background Technology

[0002] The annealing furnace is one of the three major thermal equipment in a glass production line. Its function is to controllably reduce the temperature of the glass sheets from 600-650℃ to 70-90℃ according to the requirements of the annealing process. It adopts an all-steel, all-electric structure, composed of several sections, and is longitudinally divided into several zones according to the annealing curve. Each zone employs different heating and cooling systems based on the glass sheet temperature and annealing process requirements to achieve proper annealing and reasonable cooling. Because the annealing furnace is a closed structure, the environment inside the furnace needs to be monitored in real time during the annealing and cooling process. Generally, the annealing furnace is designed with observation windows on both side walls, with window sashes at the outer ends. During normal production, the window sashes are closed to provide insulation for the annealing furnace. Traditional observation windows are inconvenient to open. When opening the window, the temperature of the window is too high, so operators must first take protective measures, open the quick clamp, and then open the observation window. Traditional observation windows will cause local heat leakage during the opening process, affecting the stability of the kiln's internal temperature. After the window is opened, the airflow inside and outside the kiln is connected through the observation window, causing local heat leakage in the kiln body, which will have a certain impact on the stability of the kiln's internal temperature and also pose certain safety hazards. Operators are easily burned by the hot airflow inside the kiln if they do not wear appropriate protective equipment.

[0003] To address the aforementioned issues, patent application number 202322974913.0 discloses an online coated glass observation window device. This device includes a device body, an isolation pad, a sealing layer, and an observation glass. The observation window device is installed on the shell of a tin bath, transition roller table, and annealing furnace area. The device body has a frame structure, and the observation glass is mounted on the device body. The inner side of the observation glass is covered by the isolation pad, and the outer side is the observation side. The isolation pad and the observation glass are bonded together by the sealing layer, which is formed by rapidly drying sealant. The observation glass is connected to the isolation pad through the sealing layer to ensure airtightness. This utility model provides an online coated glass observation window device that requires low-frequency replacement, can quickly form a sealing layer (within half an hour), and is relatively easy to modify from existing devices. However, it cannot solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a self-closing observation window structure for glass annealing furnaces is provided, which is convenient to open or close, allows staff to observe the furnace environment in real time, avoids local heat leakage, prevents the opening of the observation window from affecting the temperature stability inside the furnace, avoids scalding staff, and is conducive to improving safety.

[0017] Figure 1 This is a schematic diagram of the structure of the self-closing observation window of the glass annealing furnace in an embodiment of this utility model. The components are labeled as follows: observation window housing-10, observation window-20, observation window frame-21, fixing pressure plate-22, transparent glass plate-23, locking piece-24, sealing ring-25, self-closing window sash assembly-30, rotating rod-31, movable window sash body-32, and counterweight-33. Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] Figure 1 This is a schematic diagram of the structure of the self-closing observation window of the glass annealing furnace in an embodiment of this utility model.

[0020] like Figure 1As shown, the self-closing fan observation window structure for a glass annealing furnace provided by this utility model includes an observation window housing 10 and an observation window 20 disposed on the observation window housing 10. The observation window 20 is equipped with a self-closing fan assembly 30, which can be easily opened or closed. This allows the observation window 20 and the self-closing fan assembly 30 to facilitate real-time observation of the furnace environment by personnel, preventing localized heat leakage, avoiding disruption of furnace temperature stability due to opening the observation window, and preventing burns to personnel, thus improving safety.

[0021] like Figure 1 As shown, the observation window 20 includes an observation window frame 21 and a fixed pressure plate 22. The observation window frame 21 is set on the observation window housing 10. The fixed pressure plate 22 is movably connected to the observation window frame 21. The fixed pressure plate 22 is connected to the observation window frame 21 by means of a hinge, and a transparent glass plate 23 is on the fixed pressure plate 22. The transparent glass plate 23 allows the staff to observe the environment inside the kiln in real time, and to control the annealing and cooling process of the glass preform.

[0022] A locking piece 24 is provided on the observation window frame 21. The locking piece 24 is installed on the observation window frame 21 by screws, so that the locking piece 24 is rotatably set on the observation window frame 21. Under the action of gravity, the locking piece 24 is vertically downward and abuts against the fixed pressure plate 22, limiting the fixed pressure plate 22 and preventing the fixed pressure plate 22 from flipping outward, thus improving the reliability of the structure.

[0023] A sealing ring 25 is provided between the observation window frame 21 and the fixed pressure plate 22. The sealing ring 25 is made of aluminum silicate ceramic fiber, which has excellent high temperature resistance and heat insulation performance, can avoid local heat leakage, and helps to avoid affecting the temperature stability inside the kiln.

[0024] The self-closing window assembly 30 includes a rotating rod 31 and a movable window body 32. The rotating rod 31 is L-shaped, and one end of the rotating rod 31 is rotatably mounted on the observation window housing 10. The movable window body 32 is located inside the observation window housing 10 and its size is adapted to the fixed pressure plate 22. By rotating the rotating rod 31, the movable window body 32 can be rotated, thereby removing the obstruction of the transparent glass plate 23 by the movable window body 32. This allows staff to observe the kiln environment in real time, making it easier for them to monitor the annealing and cooling process of the glass preform, preventing burns to staff and improving safety.

[0025] A counterweight 33 is provided on the rotating rod 31. The counterweight 33 is located at one end of the rotating rod 31 outside the observation window box 10. After the operator releases the force applied to the rotating rod 31, the counterweight 33 drives the rotating rod 31 to reverse under the action of gravity, causing the movable window sash body 32 to reverse in the direction of the fixed pressure plate 22. The movable window sash body 32 abuts against the fixed pressure plate 22, blocking the transparent glass plate 23. The movable window sash body 32 is filled with heat insulation material, which can further prevent local heat leakage, prevent the opening of the observation window from affecting the temperature stability inside the kiln, prevent burns to the operators, and improve safety.
