Description

Technical Field

[0001] This utility model relates to the field of microcrystalline glass product manufacturing, and in particular to a microcrystalline glass material channel device. Background Technology

[0002] Microcrystalline glass is a polycrystalline solid material containing microcrystals, produced by controlled nucleation and crystallization of base glass with specific compositions at certain temperatures. During the manufacturing process, microcrystals continuously precipitate as the molten glass cools. A feed channel is used to transport molten glass from the furnace to the forming device. The feed channel includes a main body and a lip brick. The inventors know that the main body of the feed channel is constructed of refractory bricks, and a lip brick containing a guide section is installed at the outlet of the feed channel. During the process of flowing from the main body of the feed channel and into the lip brick, the molten glass is exposed to the air without obstruction, causing the temperature of the molten glass to drop and affecting the forming process. Simultaneously, microcrystals precipitate from the cooling molten glass, also affecting the quality of the final product. Furthermore, some of these microcrystals adhere to the refractory bricks, further affecting the transport process. Therefore, it is necessary to promptly remove these microcrystals. Methods known to the inventors for removing adhered microcrystals include crushing and replacing the refractory bricks. The crushing method involves physically destroying and cleaning the attached microcrystals. This method inevitably damages the refractory bricks. Replacing the refractory bricks requires dismantling the constructed feed channel and rebuilding it with new refractory bricks, necessitating furnace shutdown, which is time-consuming, labor-intensive, and extremely costly. Therefore, a feed channel that prevents the temperature at the outlet from becoming too low is needed. Utility Model Content

[0003] The purpose of this invention is to provide a microcrystalline glass feed channel device to solve the problems existing in the prior art. By using an insulating component to seal the outlet end of the feed channel body, the molten glass flowing out of the feed channel body is not directly exposed to the air, resulting in less heat loss from the molten glass and preventing premature solidification, thus allowing subsequent forming operations to proceed smoothly. The amount of microcrystal precipitation is minimal, and even if precipitation occurs, it adheres to the insulating component rather than the refractory bricks. Cleaning or replacing the insulating component will not damage the refractory bricks.

[0004] To achieve the above purpose, the present invention provides the following solutions:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of this invention is to provide a microcrystalline glass feed channel device to solve the problems existing in the prior art. By using an insulating component to seal the outlet end of the feed channel body, the molten glass flowing out of the feed channel body is not directly exposed to the air, resulting in less heat loss from the molten glass and preventing premature solidification, thus allowing subsequent forming operations to proceed smoothly. The amount of microcrystal precipitation is minimal, and even if precipitation occurs, it adheres to the insulating component rather than the refractory bricks. Cleaning or replacing the insulating component will not damage the refractory bricks.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a microcrystalline glass feed channel device, including a feed channel body, an insulation component, and a lip brick 2. Multiple refractory bricks 1 are used to construct the feed channel body. The insulation component is located at the discharge end of the feed channel body and has a connecting channel 8 for connecting to the feed channel body. The insulation component is in contact with the refractory bricks 1. A drainage section is provided inside the lip brick 2, and the connecting channel 8 connects to the inlet end of the drainage section. The insulation component is in contact with the lip brick 2. After the molten glass flows out of the feed channel body, it first enters the connecting channel 8 and then the drainage section, preventing it from being completely exposed to air and achieving heat preservation of the molten glass. Even if microcrystals precipitate, they will adhere to the insulation component. Removing the microcrystals only requires cleaning or replacing the insulation component, without damaging the refractory bricks 1 or requiring the dismantling of the feed channel. Finally, the molten glass flows into the calendering roller 7 for machining.

[0031] like Figure 2 As shown, the insulation component includes a flame-deflecting brick 3, side bricks 4, and a bottom brick 5. The flame-deflecting brick 3 is positioned above and opposite the bottom brick 5. Two side bricks 4 are respectively positioned on both sides of the flame-deflecting brick 3 and the bottom brick 5. The flame-deflecting brick 3, side bricks 4, and bottom brick 5 together form a connecting channel 8. The insulation component has a modular structure, with a simple overall structure, facilitating production, cleaning, and maintenance.

[0032] The flame deflector brick 3 is connected to a flame deflector brick height adjustment device, which drives the flame deflector brick 3 to move vertically. When the lower edge of the flame deflector brick 3 disengages from the side brick 4, the connecting channel 8 connects to the outside, allowing external cold air to enter the connecting channel 8 and providing appropriate cooling when the molten glass is overheated. The rising height of the flame deflector brick 3 can be controlled, thus controlling the flow rate of cold air entering the connecting channel 8 and preventing the formation of a large number of microcrystals within the connecting channel 8. Figure 1 and Figure 2As shown, in a preferred embodiment, the top of the flame deflector brick 3 is provided with a connecting part for connecting a flame deflector brick height adjustment device, and the fixing part of the flame deflector brick height adjustment device is fixedly connected to the connecting part. The connecting part includes a vertical connecting hole 301 and a horizontal connecting hole 302, wherein the vertical connecting hole 301 is a bolt hole, and the flame deflector brick height adjustment device can be fixed to the vertical connecting hole 301 by a vertical bolt. The horizontal connecting hole 302 can be a smooth hole or a bolt hole. When the horizontal connecting hole 302 is a smooth hole, a rope-like connecting device such as hemp rope, iron wire, cable, etc. can pass through the smooth hole and connect to the flame deflector brick height adjustment device. When the horizontal connecting hole 302 is a threaded hole, the flame deflector brick height adjustment device is connected to the flame deflector brick 3 by a bolt. The vertical connecting hole 301 and the horizontal connecting hole 302 can be used simultaneously or individually.

[0033] like Figure 3 As shown, the flame-blocking brick 3 can be a structure made up of multiple bricks.

[0034] like Figure 1 As shown, the discharge end of the material channel body is provided with a material channel gate 6 for controlling the material flow interruption. The material channel gate 6 is inserted into the material channel body, and the plate surface of the material channel gate 6 is perpendicular to the axis of the material channel body. In a preferred embodiment, the material channel gate 6 is connected to a material channel gate drive device.

[0035] like Figure 1 As shown, the refractory brick 1 is provided with a channel temperature measuring hole 101 for inserting a temperature measuring device into the channel. The inserted temperature measuring device can monitor the temperature of the glass melt in the channel in real time, and indirectly reflect the state of the glass melt.

[0036] like Figure 1 As shown, the refractory brick 1 is provided with a channel electrode hole 102 for inserting a heating electrode into the channel. In this invention, electrode heating is used to heat the molten glass. Electrode heating provides rapid temperature rise and high electrothermal conversion efficiency, making it suitable for rapid temperature increase of the fluid. The operating state of the heating electrode is controlled based on the monitoring results of the temperature measuring device in the channel, and it is activated when heating is required. Other types of heating devices can also be inserted into the channel electrode hole 102 in this invention.

[0037] like Figure 1 As shown, the refractory brick 1 is provided with refractory brick heating holes 103 for inserting heating devices into the refractory brick 1. Increasing the temperature of the refractory brick 1 can effectively reduce the heat loss at the interface between the molten glass and the refractory brick 1, and prevent the precipitation of microcrystals at the interface between the molten glass and the refractory brick 1, thus eliminating the problem of microcrystals adhering to the refractory brick 1 from the source.

[0038] like Figure 1 and Figure 2As shown, the side brick 4 is provided with a connecting channel heating hole 401 for inserting a heating device into the connecting channel 8. When the discharge end of the material channel body is well sealed but the temperature of the discharged molten glass is still not high enough, the molten glass in the connecting channel 8 can be heated to increase the temperature of the molten glass. Figure 1 As shown, in a preferred embodiment, the lip brick 2 is provided with a guide heating hole 201, which can heat the glass liquid in the guide section.

[0039] like Figure 1 As shown, a lifting ramp is set near the discharge end of the material channel body. When the molten glass flows through, the upper layer of uniform molten glass can flow out from the discharge end, while the lower layer of molten glass with uneven contents will flow back, ensuring the quality of the finished microcrystalline glass.
