Description
Technical Field
[0001] This utility model belongs to the field of cooling technology and relates to a cooling device for the bridge bricks on the top of the electrode of a cover plate kiln. Background Technology
[0002] A cover glass furnace is a high-temperature equipment specifically designed for producing cover glass. It heats raw glass to a molten state and processes it through a series of steps to ultimately obtain cover glass products that meet the required specifications. The temperature of the cover glass furnace is controlled at around 1600 degrees Celsius. Due to the long-term high-temperature environment inside the furnace, different glass raw materials can corrode the furnace material, causing molten glass to gradually leak through certain gaps in the furnace.
[0003] During routine electrode advancement operations, the molten glass in the electrode gaps leaks out again due to compression. Currently, the method used is air cooling via added cooling ducts. While this method can accurately cool the leaking areas, it is unstable and affected by the ambient temperature. Furthermore, its cooling effect is limited; it only cools the already leaked molten glass, leaving the molten glass inside the gaps uncooled. Prolonged molten glass leakage poses a safety hazard in production and also affects product quality. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings:
[0027] like Figure 1 He Ru Figure 4 As shown, this utility model provides a cooling device for the bridge brick at the top of the electrode of a covered kiln, including a bridge brick 1, an electrode 2, a water-cooled plate 3, and a fixing assembly. The fixing assembly includes a steel structure 5 and a water-cooled fixing frame 6. The bridge brick 1 is disposed at one end of the electrode 2, and the water-cooled plate 3 is fixedly installed on one side of the bridge brick 1. The electrode 2 is disposed at one end of the water-cooled plate 3, and a load-bearing wall is disposed at the other end of the water-cooled plate 3. The fixing assembly is disposed on the other side of the water-cooled plate 3 and is fixedly connected to the water-cooled plate 3 and the load-bearing wall through a connector 4. The water-cooled fixing frame 6 is nested on the steel structure 5 and is fixedly connected to the steel structure 5 and the water-cooled plate 3 through a connector 4. One side of the steel structure 5 is fixedly connected to the load-bearing wall.
[0028] Specifically, the bridge brick 1 is located on the left side of the water-cooled plate 3. Electrodes 2 are located at the lower ends of the bridge brick 1 and the water-cooled plate 3. A load-bearing wall is located at the upper end of the water-cooled plate 3. A fixing component is located on the right side of the water-cooled plate 3. In this embodiment, the height of the bridge brick 1 is adapted to the height of the water-cooled plate 3. The fixing component includes a steel structure 5 and a water-cooled fixing frame 6. The steel structure 5 is L-shaped, and its shorter end is fixedly connected to the load-bearing wall. The fixing connection includes welding and detachable connection. Here, the fixing connection is welding. The water-cooled mounting bracket 6 is nested on the steel structure 5. Fasteners 62, which are nuts, are provided on the outside of the water-cooled mounting bracket 6 and can be installed at different heights on the outside of the water-cooled mounting bracket 6. The connector 4 includes a first connector 41 and a second connector 42. The second connector 42 is located at the lower end of the first connector 41. The first connector 41 passes through the fastener 62 and can be fixedly connected to the water-cooled plate 3, specifically by threaded connection. Under the action of being fastened on all sides, the water-cooled plate 3 can cool the bridge brick 1. The second connector 42 is fixedly connected to the electrode 2, specifically by welding.
[0029] like Figure 3As shown, the water-cooled mounting bracket 6 includes a first mounting bracket and a second mounting bracket. The second mounting bracket is installed on both sides of the first mounting bracket and is connected in a detachable manner. The specific structure of the first mounting bracket is as follows: two rectangular plates of the same structural size are arranged in parallel, and two first square plates are set between the two rectangular plates and installed at both ends. At the same time, a certain distance is left between one end of the rectangular plate and the first square plate, which can be adjusted according to the actual situation. Finally, the rectangular plate and the first square plate can be connected by welding or as an integral structure. The second mounting bracket is installed on both sides of the first mounting bracket and is located at the lower end of the first mounting bracket. The second mounting bracket is composed of a second square plate and a polygonal plate. The second square plate is the same size as the first square plate and overlaps with it. They are connected by fasteners 61, which are screws or bolts. Fasteners 62 are installed on the outside of the polygonal plate and are fixed by welding.
[0030] like Figure 2 As shown, the water-cooled plate 3 uses a top-in, bottom-out water circulation method, consisting of an inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 and the outlet pipe 32 are independent of each other and arranged side by side. The inlet pipe 31 is equipped with a water inlet 33, and the outlet pipe 32 is equipped with a water outlet 34. The inlet pipe 31, the outlet pipe 32, the water inlet 33, the water outlet 34, the first fixing frame, and the second fixing frame are made of stainless steel. To effectively increase the cooling area of the bridge brick 1, the inlet pipe 31 and the outlet pipe 32 adopt a square tube shape with dimensions of 400×20×20mm and a wall thickness of 3-8mm, preferably 5mm. This has the following advantages: the 5mm square tube maintains a certain strength and rigidity while being lighter in weight, which helps to reduce the burden on the overall structure and save material costs; the small square tube is easier to cut, bend, and process, and can adapt to more complex structures and space constraints, meeting diverse usage needs; it can provide a larger surface area to volume ratio, which is conducive to rapid heat transfer and dissipation.
[0031] Using stainless steel offers advantages such as high thermal conductivity and low fluid resistance. High thermal conductivity: Stainless steel has excellent thermal conductivity, enabling rapid heat transfer from the fluid to the cooling medium, thus improving heat dissipation efficiency. In water flow cooling systems, stainless steel pipes can quickly dissipate heat into the air or cooling water, ensuring the system temperature remains within a controllable range. Low fluid resistance: The smooth inner wall of stainless steel pipes reduces fluid resistance, minimizing energy loss and increasing water flow rate and velocity. This helps increase the amount of water passing through the pipe per unit time, thereby improving heat dissipation efficiency.
[0032] The inlet pipe 31 and outlet pipe 32 control the temperature by adjusting the water flow rate, keeping it below 40 degrees Celsius. The water flow rate can be adjusted according to actual needs to adapt to different heat dissipation requirements. For example, in summer or when the equipment is under high load, the water flow rate can be increased to improve heat dissipation efficiency; while in winter or when the equipment is under low load, the water flow rate can be reduced to save energy. Compared to air cooling, water cooling is generally more efficient because water has a much higher heat transfer coefficient than air. This means that under the same heat dissipation requirements, water cooling can consume less energy, thus contributing to energy conservation and emission reduction. Compared to air-cooled systems, water-cooled systems are generally quieter. Because water cooling does not require mechanical components such as fans to generate airflow for heat dissipation, it avoids the noise generated by fan operation.
[0033] The water inlet pipe 31 includes an upper water inlet pipe and a lower water inlet pipe. The upper water inlet pipe is located on the same side as the lower water inlet pipe and is interconnected. The water inlet 33 is located on the side of the upper water inlet pipe away from the lower water inlet pipe. The water outlet pipe 32 includes an upper water outlet pipe and a lower water outlet pipe. The upper water outlet pipe is located on the same side as the lower water outlet pipe and is interconnected. The water outlet 34 is located on the side of the upper water outlet pipe away from the lower water outlet pipe.
[0034] The connector 4 is located on the side of the steel structure 5 away from the bridge brick 1. In this embodiment, the connector 4 is a screw. The first connector 41 passes through the steel structure 5 and the fastener 62 from the outside to the inside and is threaded to the water cooling plate 3. The second connector 42 passes through the steel structure 5 from the outside to the inside and is welded to the electrode 2.
[0035] This utility model discloses a cooling device for the bridge bricks on the top of the electrode in a cover plate kiln. The air-cooling device is modified into a liquid-cooling device. One side of the water-cooled fixing frame 6 is fixedly connected to the load-bearing wall. The water-cooled plate 3 is installed at the lower end of the load-bearing wall. The first connecting piece 41 passes through the steel structure 5 and the water-cooled fixing frame 6 and is fixedly connected to the water-cooled plate 3, so that the water-cooled plate 3 cools the bridge brick 1. The temperature of the bridge brick 1 is kept below 40 degrees Celsius by the water flow. The second connecting piece 42 passes through the steel structure 5 and is connected to the electrode 2, which reduces the risk of glass melt penetration.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
