Description

Technical Field

[0001] The invention relates to the technical field of glass production equipment, and in particular to a platinum channel and a discharging method. Background Art

[0002] The manufacturing process of substrate glass and carrier glass mainly includes the kiln process, the platinum channel process, and the molding process. First, in the kiln process, the kiln melts the raw materials into liquid to obtain glass liquid. Then, in the platinum channel process, the platinum channel is used to clarify and homogenize the glass liquid. Finally, in the molding process, the molding equipment makes the glass liquid into glass semi-finished products.

[0003] Among them, the platinum channel is the transition section where the glass liquid flows from the kiln to the molding equipment. The platinum channel is divided into three sections according to its function: clarification section, stirring section, and feeding section, and the three sections correspond to three pipelines: clarification pipeline, stirring pipeline, and feeding pipeline.

[0004] Among them, the function of the feeding section is to regulate the temperature of the glass liquid flowing from the stirring section to meet the temperature requirements of the glass liquid for the molding equipment. In addition, the feeding section is the last section of the platinum channel, with the front end docked with the stirring section and the rear end docked with the molding equipment. Therefore, the connection reliability between the feeding pipe and the stirring pipe is particularly important. In the prior art, the feeding pipe is generally docked with the stirring pipe through a flange, and the flange also needs to be connected to the external connection structure to ensure the structural stability of the feeding section.

[0005] When abnormal blockage occurs in the molding equipment and it is difficult to deal with, the glass liquid in the feed pipe needs to be emptied in time to ensure the safety of the molding equipment. The usual practice is to return the glass liquid in the feed pipe to the stirring pipe and discharge it through the discharge port set on the stirring pipe. During the emptying of the glass liquid, the temperature of the feed pipe drops sharply, and the temperature at the rear end of the feed pipe will be much lower than the temperature at the front end. Under the effect of thermal expansion and contraction, the front end of the feed pipe will shrink toward the rear end, that is, the feed pipe as a whole will shrink toward the side of the molding equipment, which can easily lead to stress concentration at the front end of the feed pipe, causing tearing damage, high repair cost and high repair difficulty.

[0006] Therefore, the above problems need to be solved urgently. Summary of the invention

[0056] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0057] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0058] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0059] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0060] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0061] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0062] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0063] See also Figures 1 to 4 The present embodiment provides a platinum channel, which is used to clarify and homogenize the glass liquid supplied by the kiln and then transport it to the molding equipment. The platinum channel includes a clarification pipe 100, a stirring pipe 200 and a feeding pipe 300. The clarification pipe 100 and the stirring pipe 200 are connected by a first flange 400, and the stirring pipe 200 and the feeding pipe 300 are connected by a second flange 500. The inlet of the clarification pipe 100 is connected to the outlet of the kiln, and the stirring pipe 200 is provided with a discharge port 201. The outlet of the feeding pipe 300 is connected to the inlet of the molding equipment.

[0064] Further, the platinum channel also includes a bracket 1 and a connecting mechanism. The bracket 1 is configured to support the feed pipe 300. The connecting mechanism is arranged between the feed pipe 300 and the external connecting structure, and / or, the connecting mechanism is arranged between the bracket 1 and the external connecting structure. The connecting mechanism is configured to elastically connect the feed pipe 300 to the external connecting structure, and is configured to guide the feed pipe 300 to extend and retract near one side of the stirring pipe 200.

[0065] It should be noted that the bracket 1 in this embodiment is a steel structure frame used to support and reinforce the feed pipe 300 in the prior art. The bracket 1 and the feed pipe 300 are rigidly connected. The heat of the feed pipe 300 will be directly transferred to the bracket 1, so that the bracket 1 and the feed pipe 300 will expand and contract together, which will not be described in detail. Figure 1 The arrow in is the direction in which the connection mechanism guides the stirring pipe 200 to expand and contract. In addition, the external connection structure is a wall or ground in the factory area, etc., so it is not described in detail in this embodiment.

[0066] It can be understood that by elastically connecting the feed pipe 300 to the external connection structure through a connecting mechanism, a rigid connection between the front end of the feed pipe 300 and the external connection structure can be avoided, thereby reducing or even avoiding the stress concentration at the front end of the feed pipe 300 causing tearing damage due to thermal expansion and contraction.

[0067] It can also be understood that the connection mechanism is used to guide the side of the feed pipe 300 close to the stirring pipe 200 to expand and contract, that is, the connection mechanism is used to guide the front end of the feed pipe 300 to expand and contract, thereby further reducing the stress concentration at the front end of the feed pipe 300.

[0068] See also Figure 5 This embodiment further provides a discharging method based on the above-mentioned platinum channel, and the discharging method comprises the following steps:

[0069] Reducing the feeding reduces the glass liquid output of the furnace; thus, the discharge pressure of the supply pipe 300 can be reduced.

[0070] To discharge, open the discharge port 201 of the stirring pipe 200, and the glass liquid in the supply pipe 300 flows back into the stirring pipe 200 and is discharged through the discharge port 201; it should be noted that the supply pipe 300 is arranged at an angle, and the lowest point is close to the discharge port 201, so that the glass liquid in the supply pipe 300 can flow to the discharge port 201, which will not be repeated.

[0071] During the primary temperature control, the platinum channel performs heating power compensation so that the temperature of the feed pipe 300 is reduced as expected. It should be noted that the heating structure and working principle of the platinum channel are both prior arts and will not be elaborated in this embodiment.

[0072] Detect the expansion and contraction amount, and periodically detect the expansion and contraction amount of the feed pipe 300; in this way, the expansion and contraction amount of the feed pipe 300 can be controlled at all times, and the tearing of the feed pipe 300 can be further avoided.

[0073] Secondary temperature control, according to the expansion and contraction amount of the feed pipe, the feed pipe 300 is coated with insulation material. It can be understood that by coating the feed pipe 300 with insulation material, on the one hand, it can prevent the feed pipe 300 from dissipating heat too quickly, and further avoid the situation where the feed pipe 300 is torn. On the other hand, it can reduce the heating power of the platinum channel and save energy. It should be noted that in this embodiment, the insulation material selects refractory insulation cotton with a thickness of 25 mm. It should also be noted that the unloading time of the glass liquid is usually about 2.5-3 hours. In this embodiment, two refractory insulation cottons are provided. The first refractory insulation cotton is coated on the feed pipe 300 at the 20th minute after unloading, and the second refractory insulation cotton is coated on the feed pipe 300 at the 60th minute.

[0074] In order to further reduce the energy consumption of the platinum channel, the unloading method also includes the following steps:

[0075] After the discharge is completed, the heating temperature of the platinum channel is maintained at 1250 degrees. It can be understood that the operating power to maintain the heating temperature at 1250 degrees is 70KW, which is significantly reduced compared to the 80KW power required to maintain the dimension at 1320 degrees in the prior art after the discharge of the platinum channel. In addition, the empty burning temperature of the platinum channel is lower, which helps to reduce the risk of organizational structure changes when the platinum pipe is empty, thereby reducing the probability of platinum defects.

[0076] The unloading method also includes the following steps:

[0077] When the glass liquid is restored, the expansion and contraction of the feed pipe 300 is periodically detected, and the insulation material is removed and the heating power of the platinum channel is adjusted according to the detection result. Such an arrangement can meet the requirement that the temperature of the glass liquid meets the cooling gradient when the glass liquid is cooled.

[0078] Please continue reading Figures 1 to 4 Generally speaking, the feed pipe 300 is usually composed of multiple sections of platinum pipes, and two adjacent sections of platinum pipes are connected by flanges. In this embodiment, the feed pipe 300 is divided into four sections, which are connected into one by three flanges, and the feed pipe 300 is connected to the stirring pipe 200 by the second flange 500.

[0079] Specifically, the connection mechanism includes at least one suspension assembly 3, and the suspension assembly 3 is used to suspend the feed pipe 300 on the external connection structure. In the present embodiment, four suspension assemblies 3 are provided, and the four suspension assemblies 3 evenly suspend the four positions of the feed pipe 300 to the external connection structure. At the same time, in order to avoid damage to the feed pipe 300 when suspending the feed pipe 300, the four suspension assemblies 3 are connected to the four flanges on the feed pipe 300 in a one-to-one correspondence. In the present embodiment, the structures of the four suspension assemblies 3 are consistent, and the structure of the suspension assembly 3 connected to the second flange 500 is used as an example to illustrate.

[0080] The suspension assembly 3 includes a mounting member 31 and a suspension member 32. The mounting member 31 is arranged on the external connection structure, and a strip hole 311 is formed through the mounting member 31, and the strip hole 311 is arranged along the extension direction of the feed pipe 300. The upper side of the suspension member 32 movably passes through the strip hole 311 and is movably connected to the mounting member 31, and the lower side of the suspension member 32 is connected to the feed pipe 300. In this suspension assembly 3, the lower side of the suspension member 32 is connected to the second flange 500. With such a configuration, the suspension member 32 driven by the feed pipe 300 when it is extended and retracted can be guided by the strip hole 311, so that the extension direction of the feed pipe 300 can be guided, which helps to further reduce the tearing of the feed pipe 300.

[0081] It is understandable that after the molding equipment is overhauled, the glass liquid circulates through the feed pipe 300 again, and the feed pipe 300 will expand due to heat. If the feed pipe 300 expands too quickly, tearing damage is also likely to occur. To this end, the suspension assembly 3 also includes a limiter 33 and a second elastic telescopic member 34, the limiter 33 is adjustably arranged on the upper side of the suspension member 32, the second elastic telescopic member 34 is arranged on the suspension member 32, and the two ends of the second elastic telescopic member 34 abut the limiter 33 and the mounting member 31 respectively. In this way, the second elastic telescopic member 34 can play a certain buffering role on the suspension member 32, thereby playing a certain buffering role on the expanding feed pipe 300. It should be noted that in the present embodiment, the second elastic telescopic member 34 is a disc spring, the limiter 33 is a nut, and the nut is screwed to the upper side of the suspension member 32, which will not be described in detail.

[0082] Correspondingly, the unloading method further comprises the following steps:

[0083] When detecting the expansion and contraction amount, the displacement of the suspension member 32 and the verticality of the second flange 500 are checked every 30 minutes, and the force of the second elastic expansion member 34 acting on the suspension member 32 is adjusted accordingly. In this way, the stress concentration between the first flange 400, the suspension member 32 and the feed pipe 300 can be eliminated in time, thereby further reducing the risk of equipment damage caused by stress concentration. It is worth noting that in this embodiment, the expansion and contraction amount of the feed pipe 300 is obtained by checking the displacement of the suspension member 32 and the verticality of the second flange 500, which will not be described in detail.

[0084] In order to improve the reliability of the installation of the feed pipe 300, the bracket 1 includes a telescopic part 11 close to the stirring pipe 200 and a fixed part 12 away from the stirring pipe 200. The fixed part 12 is fixedly connected to the external connecting structure, and the connecting mechanism includes a connecting component 2 for elastically connecting the telescopic part 11 to the external connecting structure.

[0085] Specifically, the connection assembly 2 includes an adapter 21, a connector 22, a guide 23, and a first elastic telescopic member 24. The adapter 21 is disposed on the telescopic portion 11. The connector 22 is disposed on the external connection structure. The guide 23 is disposed on the connector 22, and the adapter 21 and the guide 23 are slidably matched so that the adapter 21 can slide along the movement direction of the telescopic portion 11. The first elastic telescopic member 24 is disposed on the guide 23, and the adapter 21 can compress the first elastic telescopic member 24 when the telescopic portion 11 slides toward the fixed portion 12.

[0086] When unloading, the front end of the feeding pipe 300 and the telescopic part 11 of the bracket 1 shrink toward the side where the molding equipment is located, driving the adapter 21 to slide on the guide 23 along the movement direction of the telescopic part 11. At the same time, the adapter 21 compresses the first elastic telescopic part 24.

[0087] In order to facilitate the adjustment of the force of the second elastic telescopic member 34 acting on the adapter 21 during the unloading process, the connecting assembly 2 further includes an adjusting member 25, which is adjustably arranged on the guide member 23, and the two ends of the first elastic telescopic member 24 respectively abut the adapter 21 and the adjusting member 25. It should be noted that, in the present embodiment, the adjusting member 25 is a nut screwed on the guide member 23. In addition, in the present embodiment, a guide hole is provided on the adapter 21, and the guide member 23 slides through the guide hole.

[0088] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
