[0001] This utility model relates to a heat insulation cover, specifically a heat insulation cover for a tin bath observation hole, belonging to the field of heat insulation technology for tin bath observation windows. Background Technology
[0002] The tin bath is one of the core pieces of equipment in the float glass production process. Its main function is to provide a uniform and stable melting environment for the molten glass. During the glass production process, the molten glass needs to flow from a melting furnace into the tin bath. The tin bath is lined with liquid tin, which plays a role in carrying and uniformly distributing the molten glass, ensuring that the molten glass spreads evenly in the tin bath and removing air bubbles. The main body of the tin bath has a large number of observation windows, which are currently sealed with tempered glass to allow for inward observation.
[0003] Currently, the observation window is sealed with tempered glass to allow for inward observation. However, due to the use of glass, heat around the observation window is lost through the observation hole, affecting the stability of the glass forming. Therefore, this invention provides a heat insulation cover for the observation hole of the tin bath. Utility Model Content

[0021] This utility model embodiment provides a heat insulation cover for the observation hole of the tin bath.
[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat insulation cover for a solder bath observation window includes a solder bath observation window 1 and a heat insulation cover 3. The heat insulation cover 3 is installed inside the solder bath observation window 1. A transparent observation plate 2, which is made of tempered glass, is fixedly connected inside the solder bath observation window 1. Under the action of the transparent observation plate 2, the heat insulation cover 3 can be removed from inside the solder bath observation window 1 to facilitate observation of the inside of the solder bath. The current observation window of the solder bath has two specifications: 19.5*16.5cm and 26.5*16.5cm.
[0023] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The heat insulation cover 3 includes an outer shell 31, an insulation layer 32 is fixedly connected inside the outer shell 31, and a sealing ring 33 is fixedly connected to the outer surface of the outer shell 31. The sealing ring 33 is located between the heat insulation cover 3 and the tin bath observation window 1. The insulation layer 32 is an aluminum silicate fiber blanket. Aluminum silicate fiber has the advantages of high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, small thermal expansion, and good heat insulation performance. The outer shell 31 is made of steel. The sealing ring 33 is used to seal the tin bath observation window 1 and the heat insulation cover 3 to reduce the heat loss at the tin bath observation window 1.
[0024] Please refer to it again. Figure 1 A connecting handle 4 is installed on one side of the heat insulation cover 3. One end of the connecting handle 4 is rotatably connected to one side of the heat insulation cover 3. A heat-insulating sleeve 41 is fixedly connected to the outer surface of the connecting handle 4. The connecting handle 4 is located at the center of one side of the heat insulation cover 3. Under the action of the connecting handle 4, it is easy to remove the heat insulation cover 3 from the inside of the observation window 1 of the tin bath. The heat-insulating sleeve 41 provides heat insulation and anti-scalding effect.
[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 4The insulation cover 3 has a limiting mechanism on one side that restricts its removal. The limiting mechanism includes a fixed slide 6 fixed to one side of the insulation cover 3. A sliding pin 7 is slidably connected inside the fixed slide 6. Fixing holes 11 are provided on the inner top wall and inner bottom wall of the tin bath observation window 1. One end of the sliding pin 7 is inserted into the inside of the fixing hole 11. The sliding pin 7 is L-shaped. By pushing one end of the two sliding pins 7 away from each other, the one end of the two sliding pins 7 is inserted into the inside of the two fixing holes 11 respectively to fix the position of the insulation cover 3 inside the tin bath observation window 1.
[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A rotating disk 5 is fixedly connected to the outer surface of the connecting handle 4. The outer surface of the rotating disk 5 is provided with a pressing groove 51. One end of the sliding pin 7 slides inside the pressing groove 51. By rotating the connecting handle 4 on one side of the heat insulation cover 3, the rotating disk 5 is driven to rotate. The pressing groove 51 presses one end of the sliding pin 7, causing the sliding pin 7 to slide on the fixed slide 6, so that the other end of the sliding pin 7 is pulled out or inserted from the inside of the fixed hole 11.
[0027] Working principle: The heat loss from the solder bath through the observation window 1 is reduced by the heat insulation layer 32 and the sealing ring 33. When it is necessary to observe the inside of the solder bath, the rotating disk 5 is driven to rotate on one side of the heat insulation cover 3 by rotating the connecting handle 4. The squeezing groove 51 squeezes one end of the sliding pin 7, so that one end of the two sliding pins 7 is pulled out from the inside of the fixing hole 11. The heat insulation cover 3 is removed from the inside of the observation window 1 of the solder bath by the connecting handle 4. The inside of the solder bath can be observed through the transparent observation plate 2.
