[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0036] At present, judging from the development of science and technology, the development of electronic products and the automobile industry is becoming more and more extensive, and most fields are inseparable from glass components. Therefore, the output and quality of the glass manufacturing industry also need to gradually break through existing technologies.
[0037] The inventors of the present application have discovered that the production of glass requires melting raw materials to form molten glass, which can only be formed into the desired glass products after some types of transportation and processing. A glass kiln is indispensable for melting the raw materials. After the glass kiln melts the raw materials at high temperature to form molten glass, it needs to use a platinum channel to transport the molten glass. During the transportation process and the final stirring and discharge process, the inside of the platinum channel will form a dead corner where the molten glass can be retained due to the change of flow direction or storage of the molten glass. When the retained molten glass no longer flows with the mainstream molten glass, it is impossible to ensure that the temperature of the molten glass does not change, and the retained molten glass will be in a gradually solidifying state. When the mainstream glass contacts the retained molten glass, the semi-solidified molten glass will be mixed with the mainstream molten glass through inertia, thereby affecting the homogenization and viscosity of the molten glass, which directly affects the quality of the glass products, for example: the output quality of the substrate glass.
[0038] In order to solve the problem of glass liquid being retained in the platinum channel, the following technical solutions can be implemented:
[0039] Reference Figure 1 As shown, the present application proposes a platinum channel, which mainly includes: a channel body 1, which is used to transport glass liquid; the channel body 1 is composed of a plurality of pipe sections connected by a bending structure, so that the glass liquid in the channel body can change the flow direction; a heating component 2, which is arranged on the outer wall of the channel body 1, and is used to maintain the temperature of the transported glass liquid;
[0040] A guiding structure 10 is disposed on the inner wall of each bending structure to facilitate the glass liquid at the bending structure to flow into the mainstream glass liquid discharge channel body 1 .
[0041] With the above structure, the platinum channel is one of the important components for transporting the molten glass in the kiln. Since the glass liquid needs to be kept warm, adjusted and processed for homogenization during the transportation process, the platinum channel is also divided into several functional pipe sections, such as a heat preservation and transportation section, a stirring section, and a storage and discharge section. Due to the different functions of each pipe section, different transportation directions or storage structures will be formed in the platinum channel. Therefore, various bending structures are formed on the wall of the platinum channel to ensure the processing and transportation of the glass liquid by each functional pipe section. The technical key points of the present application are: a guiding structure 10 is provided on each bending structure, and the guiding structure 10 can cause the glass liquid to flow in the original direction, so as to quickly merge into the mainstream glass liquid, so as to avoid the phenomenon of accumulation and solidification of the glass liquid, which affects the quality of the glass liquid, and the guiding structure 10 also cooperates with the heating component 2 to prevent the glass liquid from solidifying during the guiding process. When implementing the technical method of the present application, a guide structure 10 can be provided on all inner walls with a bending structure in the channel body 1 to avoid the formation of dead corners in the platinum channel where the glass liquid can be retained, thereby achieving the purpose of improving the homogenization effect of the glass liquid and the basic glass quality.
[0042] Reference Figure 1 As shown, in some embodiments, the number of the heating components 2 is the same as the number of the guide structures 10 , and the positions of the heating components 2 correspond to the guide structures 10 arranged on the outer wall of the channel body 1 .
[0043] With the above structure, the heating component 2 can be a component that converts electrical energy into thermal energy, and by conducting thermal energy to the channel body 1, the glass liquid in the channel body 1 is kept warm to prevent the glass liquid from solidifying during transportation or stirring. In order to ensure that the glass liquid in the bending structure can quickly merge into the mainstream glass liquid, the heating component 2 and the guide structure 10 can cooperate with each other. Specifically, in the process of guiding the glass liquid to flow by the guide structure 10, the temperature of the glass liquid is ensured by the heating component 2, so that the retained glass liquid that merges into the mainstream glass liquid can maintain its viscosity, and the glass liquid that is already in the process of gradually solidifying is prevented from merging into the mainstream glass liquid and affecting its quality.
[0044] Reference Figure 1 As shown, in some embodiments, the guiding structure 10 is formed by setting a chamfer on the inner wall of the bending structure, so that the flow of the glass liquid can be guided by the arc-shaped inner wall located on the chamfer.
[0045] The purpose of adopting the above-mentioned structure and setting the inner wall of each bending structure as a chamfered structure is to change the right-angle structure of the original bending structure into an arc-shaped chamfered structure, so as to avoid forming a dead corner in the channel body 1 where the glass liquid can be retained. Under the influence of gravity or driving force, the arc-shaped chamfered structure can guide the glass liquid to flow, and then through the heat preservation support of the heating component 2, it is effectively avoided that the glass liquid that is gradually in a solidifying state merges into the mainstream glass liquid, thereby reducing the volume of the glass liquid retained in the platinum channel.
[0046] Reference Figure 2 and Figure 3 As shown, in some embodiments, the heating component 2 includes a heat-resistant shell 21 for being mounted on the outer wall of the bending structure, and a heat-releasing element 22 arranged on the heat-resistant shell 21 .
[0047] By adopting the above structure, in order to meet the insulation effect for the glass liquid, the heat-resistant shell 21 is fixedly installed on the outer wall of the channel body 1. If the heating component 2 in this application is only for the glass liquid that is prone to stagnation, the heating component 2 is set on the outer wall of the corresponding bending structure. The heat-resistant shell 21 is made of heat-resistant material so that the heat-resistant shell 21 is not easily deformed in a high temperature environment to avoid affecting the fit with the channel body 1; the heat-emitting element 22 can generate heat and conduct the heat to the channel body 1 through the heat-resistant shell 21 and its own structure until the heat acts on the glass liquid.
[0048] Reference Figure 2 and Figure 3 As shown, in some embodiments, one side of the heat-resistant shell 21 has a fitting surface that matches the outer wall of the bending structure, and the heat of the heat-releasing element 22 is conducted to the corresponding bending structure through the fitting surface.
[0049] With the above structure, one side surface of the heat-resistant shell 21 is set as a concave fitting surface, and the fitting surface is set as an arc structure adapted to the outer wall of the bending structure, so that the fitting surface on the heat-resistant shell 21 can cover a large area on the outer wall of the bending structure to increase the heat conduction efficiency.
[0050] In some embodiments, the heat-resistant shell 21 includes a heat-conducting body 21a and a heat-insulating layer 21b; a plurality of slots 211 are provided on the heat-conducting body 21a for fixing the heat-releasing element 22 in an embedded manner to form a fitting surface, and the heat-releasing element 22 is provided with terminal posts 221 for connecting a power supply on the outside of the heat-conducting body 21a; the heat-insulating layer 21b covers the side of the heat-conducting body 21a away from the fitting surface to block heat.
[0051] With the above structure, the fitting surface is formed on the heat-conducting body 21a, and the heat-releasing element 22 is also arranged on the heat-conducting body 21a, and the heat-insulating layer 21b covers the outside of the heat-conducting body 21a. When the heating component 2 is installed on the channel body 1, it can also be understood that the heat-insulating layer 21b is located on the side of the heat-conducting body 21a away from the channel body 1. The heat-insulating layer 21b can block the dispersion of heat, and the heat-conducting body 21a is made of heat-conducting material, so that the heat can be dispersed and conducted to the channel body 1 in one direction.
[0052] Reference Figure 3 and Figure 4 As shown, in some embodiments, a plurality of slots 211 are provided on the heat-resistant shell 21 , and the heat-releasing elements 22 are interlaced in each slot 211 in a winding manner, and a terminal 221 for connecting a power source is reserved on the outside of the heat-resistant shell 21 .
[0053] The above structure is adopted, that is, a plurality of stacked slots 211 are provided on the heat-conducting body 21a, and the heat-dissipating element 22 can be inserted and fixed around each stacked slot 211, so that the heat-dissipating element 22 increases the heat-dissipating area through the arrangement of the slots 211. In the present application, the connection end of the heat-dissipating element 22 is reserved outside the heat-conducting body 21a for connecting a power source; the heat-dissipating element 22 can be composed of a heating wire.
[0054] Reference Figure 1 As shown, in some embodiments, the channel body 1 includes a conveying section 11 and a stirring section 12; the conveying section 11 is used to connect the stirring section 12 with the kiln; the stirring section 12 is also provided with a containing section 13 for storing molten glass at the lower end away from the conveying section 11.
[0055] With the above structure, the channel body 1 at least includes a conveying section 11, a stirring section 12 and a containing section 13. When in use, the glass liquid melted in the kiln is transported to the stirring section 12 through the conveying section 11 for stirring to improve the homogeneity of the glass liquid, and then the stirred glass liquid is stored in the containing section 13, thereby completing the preparation work for the glass liquid to be discharged from the channel body 1. During the storage of the glass liquid, there may be a dead corner of the containing section 13 where the glass is retained, which is easy to reduce the homogeneity of the glass liquid and affect the quality of the substrate glass. Therefore, a guiding structure and a heating component 2 need to be provided in the containing section 13.
[0056] Reference Figure 1 As shown, in some embodiments, a discharge port 130 for discharging molten glass is provided at the bottom of the containing section 13; the stirring section 12 is connected to a side wall of the containing section 13 through a bending structure, and a guide structure 10 is formed on the inner wall of the bending structure.
[0057] By adopting the above structure, in order to allow the glass liquid stored in the containing section 13 to flow out smoothly, a discharge port 130 is opened at the bottom of the containing section 13, and the inner walls of the containing section 13 that form a bending structure all adopt a chamfered structure to form the above-mentioned guiding structure, thereby avoiding the formation of a dead corner for retaining the glass liquid inside the containing section 13, and in order to further prevent the glass liquid from gradually solidifying and being unable to flow, a heating component 2 in the above-mentioned embodiment is added to the outer wall of the containing section 13, and each heating component 2 can correspond to each guiding structure one by one, so that with the support of the heating component 2, the glass liquid can avoid being inhibited from flowing toward the discharge port 130 due to being in a gradually solidifying state.
[0058] Reference Figure 1 As shown, in some embodiments, the arc-shaped inner wall of the guide structure 10 gradually extends toward the discharge port 130 .
[0059] By adopting the above structure, after the arc-shaped inner wall of the guiding structure is set to gradually extend in the direction of the discharge port 130, the flow direction of the retained glass liquid can be further determined, which can not only avoid the formation of retention dead corners in the accommodating section 13 or other positions of the channel body 1, but also unify the flow direction of the retained glass liquid in various directions to flow in the direction of the discharge port 130 together, thereby reducing the glass liquid retained in the channel body 1 and improving the quality of the output substrate glass.
[0060] Reference Figure 1 As shown, in some embodiments, a stirring component 3 is further configured in the stirring section 12 for adjusting the uniformity of the glass liquid in the stirring section 12 .
[0061] With the above structure, the stirring component 3 is a stirring rod arranged in the stirring section 12, and the stirring rod can increase the homogenization degree of the glass liquid in the stirring section 12 by rotating. It should be noted that the stirring section 12 can be a stirring tank in the platinum channel, and the stirring section 12 can be located at the end position of the platinum channel to stir the glass liquid transported by the platinum channel and then discharge it.
