Description

Technical Field

[0001] The present application relates to the technical field of glass forming, and in particular to a glass discharging device, a glass forming device and a method. Background Art

[0002] During the optical glass production process, the discharge pipe is used to guide the molten glass into the forming mold. Due to the low viscosity and high upper crystallization temperature of lanthanide and heavy flint optical glasses, crystallization is prone to occur on the inner wall and at the outlet of the discharge pipe during the discharging and molding process. Crystallization can change the flow rate and direction of the molten glass, easily forming a layer of crystal particles on the glass surface or causing scratches on the glass surface, affecting production stability and product yield.

[0003] In the prior art, methods such as changing the shape of the discharge pipe and providing an insulation layer are usually adopted to prevent crystallization, but these methods have the problem of unsatisfactory effects in preventing crystallization. Summary of the Invention

[0004] Based on this, it is necessary to provide a glass discharging device, a glass forming device and a method to address the problem of poor anti-crystallization effect.

[0005] In a first aspect, a glass discharging device is provided, comprising:

[0006] Discharge pipe;

The heating circuit is used to heat the corresponding position of the discharge pipe, and the heating structure is used to heat the compensating heat-conducting structure. When the anti-crystallization mechanism is energized, a first current and a second current with opposite directions are formed on the compensating heat-conducting structure.

[0012] The second heat-conducting structure includes a second electrode sheet, which includes a second electrode body and a second heat-conducting part. The second heat-conducting part is fixedly connected to the outer wall of the discharge pipe. The second electrode body is integrally arranged at an end of the second heat-conducting part away from the discharge pipe. The second electrode body is connected to the power module through a wire and cooperates with the adjacent compensating heat-conducting structure to form a corresponding heating circuit.

[0013] In one embodiment, the first heat-conducting structure, the second heat-conducting structure and the compensating heat-conducting structure have a first cross-sectional area on a first plane, the first plane is perpendicular to the first flow direction of the current flowing through the first heat-conducting structure, the second heat-conducting structure and the compensating heat-conducting structure, and the first cross-sectional areas of the first heat-conducting structure, the second heat-conducting structure and the compensating heat-conducting structure at all locations in the first flow direction are equal; the tube wall of the discharge pipe has a second cross-sectional area on a second plane, the second plane is perpendicular to the second flow direction of the current flowing through the discharge pipe, and the second cross-sectional areas of the tube wall of the discharge pipe in the second flow direction are equal at all locations; the first cross-sectional area is equal to the second cross-sectional area.

[0014] In one embodiment, a first heating circuit and a second heating circuit are formed for each of the compensating heat-conducting structures. The first heating circuit and the second heating circuit both include the compensating heat-conducting structure and other heat-conducting structures. One end of the other heat-conducting structure is electrically connected to one end of the corresponding compensating structure through the discharge pipe. The other heat-conducting structure includes at least one of the first heat-conducting structure, the second heat-conducting structure, or other of the compensating heat-conducting structures.

[0015] The glass discharging device also includes:

[0016] a power supply module, configured to provide a first power supply signal for the first heating circuit, a second power supply signal for the second heating circuit, and a third power supply signal for the heating structure, wherein the first power supply signal includes a first positive signal and a first negative signal, and the second power supply signal includes a second positive signal and a second negative signal;

[0017] The first positive signal is electrically connected to one end of the other heat-conducting structure in the first heating circuit away from the discharge pipe, the first negative signal and the second positive signal are both electrically connected to one end of the compensation heat-conducting structure away from the discharge pipe, and the second negative signal is electrically connected to one end of the other heat-conducting structure in the second heating circuit away from the discharge pipe, so as to form the first current and the second current in opposite directions on the compensation heat-conducting structure.

[0018] In one embodiment, it further includes:

[0019] The temperature control module includes a control unit and a first temperature sensor arranged on the first heat-conducting structure, a second temperature sensor arranged on the second heat-conducting structure, a third temperature sensor arranged on the at least one compensation heat-conducting structure, and a fourth temperature sensor arranged on the discharge pipe corresponding to each heating circuit. The first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor are all electrically connected to the control unit. The control unit is used to adjust the first power supply signal, the second power supply signal and the third power supply signal according to the real-time temperature feedback from the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor, so as to correspondingly control the heating power of the first heating circuit and the second heating circuit for the discharge pipe and control the heating power of the heating structure for the compensation heat-conducting structure.

[0020] In one embodiment, it further includes:

[0021] The heat-insulating mechanism is detachably arranged on the outer wall of the discharge pipe and wraps the discharge pipe. The heat-insulating mechanism includes multiple insulation layers. The multiple insulation layers are stacked along the radial direction of the discharge pipe away from the discharge pipe, and the temperature difference between the outermost insulation layer and the discharge pipe floats within a preset range.

[0022] In a second aspect, a glass forming device is provided, comprising a glass forming mold and the glass discharging device as described above, wherein the discharging end of the discharging pipe is connected to the glass forming mold to transport the molten glass into the glass forming mold.

[0026] The molten glass liquid is controlled to flow into the discharge pipe along the feed end of the discharge pipe, and then into the glass forming mold through the discharge end, so as to be formed by the glass forming mold.

[0027] The above-mentioned glass discharging device, by providing an anti-crystallization mechanism on the outer periphery of the discharging pipe, utilizes a first heat-conducting structure, a second heat-conducting structure, and a compensating heat-conducting structure to form multiple heating circuits. By heating the discharging pipe through the heating circuits, the temperature of the discharging pipe can be more evenly controlled, so that the temperature at all locations on the discharging pipe is consistent, thereby effectively suppressing the crystallization of the glass liquid during the discharging process and improving the quality of the glass products. At the same time, each compensating heat-conducting structure forms a corresponding heating circuit with the adjacent heat-conducting structure, and the directions of the first current and the second current flowing through the compensating heat-conducting structure in the two circuits are opposite, which can effectively prevent the first current and the second current from being superimposed on the compensating heat-conducting structure and causing a large current breakdown in the compensating heat-conducting structure, thereby ensuring the safe operation of the entire device. At the same time, by cooperating with the heating structure to heat the compensating heat-conducting structure, the heating effect of each heat-conducting structure on the discharging pipe can be guaranteed, which is conducive to improving the stability of the discharging process.

[0049] See also Figure 1 and Figure 2 , Figure 1 FIG. 1 shows a schematic structural diagram of a glass discharging device in an embodiment of the present application. Figure 2 A cross-sectional view of a glass discharging device according to an embodiment of the present application is shown. The glass discharging device provided in one embodiment of the present application includes a discharging pipe 100 and an anti-crystallization mechanism 200. The discharging pipe 100 is used to convey molten glass to a glass forming mold, and the anti-crystallization mechanism 200 is used to prevent crystallization of the glass while flowing in the discharging pipe 100, thereby improving the quality of glass forming.

[0050] The anti-crystallization mechanism 200 is arranged on the outer wall of the discharge pipe 100. The anti-crystallization mechanism 200 includes a first heat-conducting structure 210, a second heat-conducting structure 220, at least one compensating heat-conducting structure 230, and a heating structure 240 arranged in a one-to-one correspondence with at least one compensating heat-conducting structure 230. The first heat-conducting structure 210 is arranged at the first end of the discharge pipe 100, the second heat-conducting structure 220 is arranged at the second end of the discharge pipe 100, and the at least one compensating heat-conducting structure 230 is arranged between the first heat-conducting structure 210 and the second heat-conducting structure 220 along the axial direction of the discharge pipe 100; for Each compensating heat-conducting structure 230 cooperates with the adjacent first heat-conducting structure 210, the second heat-conducting structure 220 and at least one of the other compensating heat-conducting structures 230 to form a heating circuit. The heating circuit is used to heat the corresponding position of the discharge pipe 100, and the heating structure 240 is used to heat the compensating heat-conducting structure 230. When the anti-crystallization mechanism 200 is energized, a first current and a second current with opposite directions are formed on the compensating heat-conducting structure 230. The first current and the second current are superimposed to form a superimposed current, and the superimposed current is less than the breakdown current of the compensating heat-conducting structure 230.

[0051] The discharge pipe 100 is a tubular structure as a whole, including a tube body 110 and a discharge channel 120 formed inside the tube body 110. The anti-crystallization mechanism 200 is fixed on the outer wall of the tube body 110. For example, it can be fixed by welding, crimping, threading, etc. When crimping or threading is used, the anti-crystallization mechanism 200 is in close contact with the outer wall of the tube body 110 to form a heat-conducting surface to achieve heat exchange between the anti-crystallization mechanism 200 and the tube body 110.

[0052] Specifically, the anti-crystallization mechanism 200 includes a first heat-conducting structure 210, a second heat-conducting structure 220, at least one compensation heat-conducting structure 230, and a heating structure 240 corresponding to the at least one compensation heat-conducting structure 230. Figure 1 and Figure 2Taking the example of a single compensating heat-conducting structure 230, the discharge pipe 100 has a first end and a second end distributed along the axial direction. In the axial direction of the discharge pipe 100, the first heat-conducting structure 210 is welded and fixed to the outer wall of the first end of the pipe body 110, and the second heat-conducting structure 220 is welded and fixed to the outer wall of the second end of the pipe body 110. The compensating heat-conducting structure 230 is welded and fixed to the outer wall between the first and second ends of the pipe body 110, that is, the compensating heat-conducting structure 230 is disposed between the first and second heat-conducting structures 210 and 220. Typically, the compensating heat-conducting structure 230 is disposed in the middle of the pipe body 110, such that in the axial direction of the pipe body 110, the distances between the compensating heat-conducting structure 230 and the first and second heat-conducting structures 210 and 220 are consistent, thereby dividing the pipe body 110 axially into two heating sections of equal length, designated as the first heating section 111 and the second heating section 112.

[0053] In this way, a first heating circuit can be formed based on the first heat-conducting structure 210, the compensating heat-conducting structure 230 and the first heating section 111, and a second heating circuit can be formed based on the second heat-conducting structure 220, the compensating heat-conducting structure 230 and the second heating section 112. When the first heating circuit and the second heating circuit are energized, a first current is generated in the first heating circuit, and heat is generated in the first heating circuit by the first current. The generated heat can then be controlled by controlling the magnitude of the first current. When the temperature of the heat generated in the first heating circuit is equivalent to the temperature of the glass liquid, the heat exchange between the molten glass liquid and the first heating section 111 can be reduced when the molten glass liquid flows through the first heating section 111. Similarly, a second current can be generated in the second heating circuit, and heat can be generated in the second heating circuit by the action of the second current. When the temperature of the heat generated in the first heating circuit is equivalent to the temperature of the glass liquid, the heat exchange between the molten glass liquid and the second heating section 112 can be reduced when the molten glass liquid flows through the second heating section 112, thereby preventing the glass liquid from crystallizing due to temperature reduction.

[0054] In an exemplary embodiment, the tube body 110, the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230 are all made of conductive materials. When the first heating circuit and the second heating circuit are energized, the tube body 110, the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230 can be regarded as conductors connected to the heating circuit.

[0055] Please refer to Figure 3, is the equivalent circuit diagram of the first heating circuit and the second heating circuit. When the anti-devitrification mechanism 200 is energized, the first heating circuit (the circuit marked with red lines in the figure) and the second heating circuit (the circuit marked with blue lines in the figure) each generate a first current and a second current. The red arrow in the figure indicates the direction of flow of the first current, and the blue arrow indicates the direction of flow of the second current. Because the first and second heating circuits share the same compensating heat-conducting structure 230, the first and second currents are superimposed on the compensating heat-conducting structure 230 to form a superimposed current. According to the formula for heat generation by current, Q = IR 2 t (where Q is the heat generated by the conductor, I is the current flowing through each conductor, R is the resistance of each conductor, and t is the duration of the current flow). It can be seen that, given a certain conductor resistance and current duration, the greater the current, the more heat is generated, making it more likely that the conductor will experience high-current breakdown or thermal breakdown, which can damage the conductor. To prevent high-current breakdown in the compensating heat-conducting structure 230, the direction of the first and second currents can be controlled. Specifically, by controlling the polarity of the power supply connected to the first and second heating circuits, the first and second currents in the compensating heat-conducting structure 230 can be directed in opposite directions. When the first and second currents are equal in magnitude, the superimposed current is approximately zero, thus preventing high-current breakdown in the compensating heat-conducting structure 230. Furthermore, to compensate for heat loss in the compensating heat-conducting structure 230 due to reduced current flow, a heating structure 240 can be provided outside the compensating heat-conducting structure 230 to heat the compensating heat-conducting structure 230 and compensate for the heat loss.

[0056] In some other embodiments, two compensating heat-conducting structures 230 are provided between the first heat-conducting structure 210 and the second heat-conducting structure 220, dividing the discharge pipe 100 into three heating sections. In this way, a first heating circuit can be formed based on the first heat-conducting structure 210, the first heating section and the first compensating heat-conducting structure 230; a second heating circuit can be formed based on the first compensating heat-conducting structure 230, the second heating section and the second compensating heat-conducting structure 230; and a third heating circuit can be formed based on the second compensating heat-conducting structure 230, the third heating section and the second heat-conducting structure 220. The first compensating heat-conducting structure 230 is shared between the first heating circuit and the second heating circuit, two currents in opposite directions are formed on the first compensating heat-conducting structure 230, and a corresponding heating structure 240 is set on the first compensating heat-conducting structure 230 to compensate for the heat loss on the first compensating heat-conducting structure 230. The second compensating heat-conducting structure 230 is shared between the second heating circuit and the third heating circuit, two currents in opposite directions are formed on the second compensating heat-conducting structure 230, and a corresponding heating structure 240 is set on the second compensating heat-conducting structure 230 to compensate for the heat loss on the second compensating heat-conducting structure 230. In this way, the temperature fluctuations from the first to the third heating sections can be reduced to prevent crystallization of the glass liquid. In specific implementation, the number of compensating heat-conducting structures 230 can be determined according to the length of the discharge pipe 100, the thermal conductivity of the discharge pipe 100, etc. For example, as the length of the discharge pipe 100 increases, more compensating heat-conducting structures 230 can be set to perform more refined segmented heating on the discharge pipe 100 to reduce heat loss when current flows through each heating segment, which is conducive to further improving the anti-crystallization effect.

[0057] In one embodiment, please refer to Figure 1 and Figure 4 The compensation heat-conducting structure 230 includes a compensation electrode sheet 231, and the compensation electrode sheet 231 includes a compensation electrode main body 2311 and a compensation heat-conducting part 2312. The compensation heat-conducting part 2312 is fixedly connected to the outer wall of the discharge pipe 100, and the compensation electrode main body 2311 is integrally arranged at the end of the compensation heat-conducting part 2312 away from the discharge pipe 100. The compensation electrode main body 2311 is connected to the power module 300 through a wire, and cooperates with other adjacent heat-conducting structures to form a corresponding heating circuit. The other heat-conducting structures include at least one of the first heat-conducting structure 210, the second heat-conducting structure 220 or other compensation heat-conducting structures 230.

[0058] The compensation electrode sheet 231 is a sheet-like structure having a certain thickness. The compensation electrode sheet 231 may include an integrally arranged compensation electrode body 2311 and a compensation heat-conducting portion 2312. The compensation heat-conducting portion 2312 is welded to the outer wall of the discharge tube 100. The compensation electrode body 2311 integrally extends from the end of the compensation heat-conducting portion 2312 away from the discharge tube 100 and is configured to connect to the power module 300 via a wire, thereby forming a corresponding heating circuit with the adjacent first heat-conducting structure 210, the second heat-conducting structure 220, or other compensation heat-conducting structures 230.

[0059] In an optional embodiment, the compensating heat-conducting portion 2312 has a welding hole 2313 extending through the thickness thereof. The welding hole 2313 is used to penetrate the discharge pipe 100 so that the compensating electrode sheet 231 can be welded and fixed to the discharge pipe 100. In a specific implementation, the welding hole 2313 in the compensating heat-conducting portion 2312 can be a closed through-hole formed by stamping. That is, the entire compensating heat-conducting portion 2312 has no notches or fractures in the circumferential direction, ensuring stable contact between the compensating heat-conducting portion 2312 and the discharge pipe 100 and improving the stability of current flow. Optionally, a strip extension portion (not shown) is formed at a corresponding position of the compensation electrode main body 2311 by stretching, and the welding hole 2313 on the compensation heat conduction portion 2312 can also be a through hole formed by bending the strip extension portion around the circumferential direction of the discharge pipe 100. The compensation heat conduction portion 2312 is formed by the strip extension portion surrounding the outer peripheral surface of the discharge pipe 100. With this arrangement, the compensation electrode sheet 231 can be prepared by prefabricated forming. Since the shape of the compensation heat conduction portion 2312 is not determined before the compensation electrode sheet 231 is welded and fixed to the discharge pipe 100, the shape and size of the welding hole 2313 are also not determined, so that the compensation electrode sheet 231 can be adapted to discharge pipes 100 of different sizes and shapes, which is beneficial to improving the versatility of the compensation electrode sheet 231.

[0060] In some other embodiments, please refer to Figure 5 The compensation heat conduction portion 2312 has a welding notch 2314 that opens in a direction away from the compensation electrode main body 2311. The welding notch 2314 is used to clamp the discharge pipe 100 so that the compensation electrode sheet 231 can be welded and fixed to the discharge pipe 100. In specific implementation, the size of the welding notch 2314 can be determined according to the outer diameter of the discharge pipe 100 to ensure that the inner wall of the welding notch 2314 can closely fit the outer wall of the discharge pipe 100. On the one hand, this can improve the welding strength between the compensation electrode sheet 231 and the discharge pipe 100, ensuring the reliability and stability of the device during use; on the other hand, it can also ensure the stable flow of current between the discharge pipe 100 and the compensation electrode sheet 231.

[0061] In one embodiment, the first heat-conducting structure 210 includes a first electrode sheet 211, which includes a first electrode body (not shown) and a first heat-conducting portion (not shown). The first heat-conducting portion is fixedly connected to the outer wall of the discharge pipe 100. The first electrode body is integrally disposed at the end of the first heat-conducting portion away from the discharge pipe 100. The first electrode body is connected to the power module 300 via a wire and cooperates with the adjacent compensating heat-conducting structure 230 to form a corresponding heating circuit. The second heat-conducting structure 220 includes a second electrode sheet 221, which includes a second electrode body (not shown) and a second heat-conducting portion (not shown). The second heat-conducting portion is fixedly connected to the outer wall of the discharge pipe 100. The second electrode body is integrally disposed at the end of the second heat-conducting portion away from the discharge pipe 100. The second electrode body is connected to the power module 300 via a wire and cooperates with the adjacent compensating heat-conducting structure 230 to form a corresponding heating circuit.

[0062] To ensure that the current on each heat-conducting structure is consistent, the first electrode sheet 211 and the second electrode sheet 221 have the same structure and shape as the compensation electrode sheet 231. Taking the first electrode sheet 211 as an example, the structure of the second electrode sheet 221 can refer to the description of the first electrode sheet 211 and will not be repeated here. The first electrode sheet 211 is a sheet-like structure with a certain thickness as a whole. The first electrode sheet 211 may include an integrally arranged first electrode body and a first heat-conducting part. The first heat-conducting part is welded and fixed to the outer wall of the discharge pipe 100. The first electrode body extends integrally from the end of the first heat-conducting part away from the discharge pipe 100 and is used to connect to the power module 300 through a wire to cooperate with the adjacent compensation electrode sheet 231 to form a corresponding heating circuit. In an optional embodiment, similar to the compensation heat-conducting part 2312, the first heat-conducting part has a welding hole 2313 provided along the thickness direction for penetrating the discharge pipe 100, so that the first electrode sheet 211 can be welded and fixed to the discharge pipe 100. In specific implementation, the structures of the first heat conducting part and the second heat conducting part are similar to those of the compensation heat conducting part 2312 . For details, please refer to the description of the compensation heat conducting part 2312 , which will not be described here.

[0063] In one embodiment, the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230 have a first cross-sectional area on a first plane, the first plane is perpendicular to the first flow direction of the current flowing through the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230, and the first cross-sectional areas of the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230 at all locations in the first flow direction are equal; the tube wall of the discharge pipe 100 has a second cross-sectional area on a second plane, the second plane is perpendicular to the second flow direction of the current flowing through the discharge pipe 100, and the second cross-sectional areas of the tube wall of the discharge pipe 100 in the second flow direction are equal at all locations; the first cross-sectional area is equal to the second cross-sectional area.

[0064] In a specific implementation, the first heat-conducting structure 210, the second heat-conducting structure 220 and the compensating heat-conducting structure 230 are arranged in parallel. Taking the first heat-conducting structure 210 as the first electrode sheet 211 as an example, the current flows along the first flow direction on the first electrode sheet 211. In the first flow direction, there is a first plane perpendicular to the first flow direction. The first electrode sheet 211 has a first cross-sectional area on the first plane, and the first cross-sectional areas of the first electrode sheet 211 at all locations in the first flow direction are equal. Such an arrangement can ensure that the first electrode sheet 211 can generate heat evenly at all locations, thereby ensuring the safety of the first electrode sheet 211 during use. At the same time, the second electrode sheet 221 and the compensation electrode sheet 231 have the same first cross-sectional area as the first electrode sheet 211. With this arrangement, since the first cross-sectional areas of the first electrode sheet 211, the second electrode sheet 221, and the compensation electrode sheet 231 are equal, according to the conductor resistance calculation formula R=ρ×L / S (wherein, R is the resistance of the conductor, ρ is the resistivity of the conductor, L is the length of the conductor, and S is the cross-sectional area of ​​the conductor), it can be seen that when the first electrode sheet 211, the second electrode sheet 221, and the compensation electrode sheet 231 are of the same size and material, the equivalent resistance of the first electrode sheet 211, the second electrode sheet 221, and the compensation electrode sheet 231 are the same, thereby ensuring that after power is turned on, the currents on the first electrode sheet 211, the second electrode sheet 221, and the compensation electrode sheet 231 are consistent, thereby generating the same amount of heat and reducing temperature fluctuations.

[0065] The discharge pipe 100 includes a first heating section 111 and a second heating section 112. Similarly, taking the first heating section 111 as an example, current flows in the first heating section 111 along a second flow direction. In the second flow direction, a second plane exists perpendicular to the second flow direction. The first heating section 111 has a second cross-sectional area on the second plane, and the second cross-sectional area is equal at all locations in the first heating section 111 along the second flow direction. This arrangement ensures uniform heating across the first heating section 111, thereby ensuring the safety of the first heating section 111 during use. Furthermore, the second heating section 112 has the same second cross-sectional area as the first heating section 111. Because the second cross-sectional areas of the first and second heating sections 111, 112 are equal, according to the resistance calculation formula for conductors, if the first and second heating sections 111, 112 have the same size and material, the equivalent resistance of the first and second heating sections 111, 112 is the same. This ensures that, when power is applied, the current in the first and second heating sections 111, 112 is consistent, generating the same amount of heat and minimizing temperature fluctuations.

[0066] In addition, the first cross-sectional area is equal to the second cross-sectional area, so that the current of each electrode sheet and the discharge pipe 100 after power is turned on is consistent, thereby ensuring temperature matching between each electrode sheet and the discharge pipe 100.

[0067] In one embodiment, please refer to Figure 1 and Figure 2 The heating structure 240 includes a resistance wire 241, which is wound around the outside of the compensation electrode sheet 231. The resistance wire 241 is connected to the compensation electrode sheet 231 through a heat-conducting medium. Both ends of the resistance wire 241 are respectively connected to the power module 300 to perform heat exchange with the compensation electrode sheet 231 through the heat-conducting medium when the resistance wire 241 is energized.

[0068] The resistance wire 241 is spirally wound around the outside of the compensation electrode sheet 231, and the resistance wire 241 is connected to the compensation electrode sheet 231 via a heat-conducting medium. When providing the heat-conducting medium, multiple contact points can be set between the resistance wire 241 and the compensation electrode sheet 231, and each contact point uses a heat-conducting medium to connect the resistance wire 241 and the compensation electrode sheet 231, so that the compensation electrode sheet 231 can be heated evenly and the heat exchange efficiency between the compensation electrode sheet 231 and the resistance wire 241 is improved. In some other embodiments, when connecting the resistance wire 241 and the compensation electrode, the heat-conducting medium can also cover the resistance wire 241 as a whole and fully contact the surface of the compensation electrode sheet 231, so as to increase the area of ​​the heat exchange interface between the resistance wire 241 and the compensation electrode, thereby further improving the heat exchange efficiency between the compensation electrode sheet 231 and the resistance wire 241. The two ends of the resistance wire 241 are respectively connected to the positive pole and the negative pole of the power module 300, so that when the power module 300 energizes the resistance wire 241, the resistance wire 241 can generate heat and transfer the generated heat to the compensation electrode sheet 231 through the heat-conducting medium to ensure that the temperature of the compensation electrode sheet 231 is consistent with the temperature of the discharge pipe 100 or slightly higher than the temperature of the discharge pipe 100 by 5°C-10°C, thereby preventing the glass liquid in the discharge pipe 100 from crystallizing due to the temperature drop.

[0069] The thermal conductive medium can be made of a thermally conductive but non-conductive material, such as thermally conductive glue, thermally conductive ceramics, etc., so that after the resistance wire 241 generates heat when energized, the generated heat can be transferred to the compensation electrode sheet 231 through the thermal conductive medium. At the same time, the non-conductive nature of the thermal conductive medium can prevent a short circuit between the resistance wire 241 and the compensation electrode sheet 231 due to conduction or affect the stability of the current in each heating circuit.

[0070] In some other embodiments, the heating structure 240 may also be implemented using structures such as silicon carbon rods or silicon molybdenum rods that can generate heat when energized, so as to adapt to high temperature environments and provide stable heat for the compensation electrode sheet 231 .

[0071] In one embodiment, a first heating circuit and a second heating circuit are formed for each compensating heat-conducting structure 230, and the first heating circuit and the second heating circuit both include the compensating heat-conducting structure 230 and other heat-conducting structures, and one end of the other heat-conducting structure is electrically connected to one end of the compensation structure through the discharge pipe 100; the other heat-conducting structures include at least one of the first heat-conducting structure 210, the second heat-conducting structure 220 or the other compensating heat-conducting structures 230.

[0072] Based on this, the glass discharging device also includes a power supply module 300, which is used to provide a first power supply signal for the first heating circuit, a second power supply signal for the second heating circuit, and a third power supply signal for the heating structure 240. The first power supply signal includes a first positive signal and a first negative signal, and the second power supply signal includes a second positive signal and a second negative signal. The first positive signal is electrically connected to the end of the other heat-conducting structures in the first heating circuit away from the discharge pipe 100, the first negative signal and the second positive signal are both electrically connected to the end of the compensating heat-conducting structure 230 away from the discharge pipe 100, and the second negative signal is electrically connected to the end of the other heat-conducting structures in the second heating circuit away from the discharge pipe 100, so as to form a first current and a second current in opposite directions on the compensating heat-conducting structure 230.

[0073] The power module 300 is connected to the first electrode sheet 211, the second electrode sheet 221, the compensation electrode sheet 231, and the resistance wire 241. Specifically, the power module 300 can independently power each heating circuit through different power signals, that is, the first heating circuit is powered by the first power signal, and the second heating circuit is powered by the second power signal. In this way, by connecting power signals of different polarities to the compensation electrode sheet 231, the current of different heating circuits on the common compensation electrode sheet 231 can be reversed, thereby preventing the compensation electrode sheet 231 from experiencing a large current breakdown. The power module 300 can also independently power the resistance wire 241 through a third power signal so that the resistance wire 241 can heat the corresponding compensation electrode sheet 231.

[0074] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 6 The glass discharging device also includes a temperature control module 400, which is electrically connected to the power module 300. The temperature control module 400 is used to collect the real-time temperature on the discharge pipe 100 and the anti-crystallization mechanism 200, so as to adjust the heating power of each heat-conducting structure and the heating structure 240 according to the real-time temperature of the corresponding positions on the discharge pipe 100 and the anti-crystallization mechanism 200, and minimize the temperature difference between various locations on the discharge pipe 100 and between the discharge pipe 100 and each heat-conducting structure, thereby reducing the temperature fluctuation on the discharge pipe 100 to improve the anti-crystallization effect.

[0075] Specifically, the temperature control module 400 includes a control unit 410 and a first temperature sensor 420 arranged on the first heat-conducting structure 210, a second temperature sensor 430 arranged on the second heat-conducting structure 220, a third temperature sensor 440 arranged on at least one compensation heat-conducting structure 230, and a fourth temperature sensor 450 arranged on the discharge pipe 100 corresponding to each heating circuit. The first temperature sensor 420, the second temperature sensor 430, the third temperature sensor 440 and the fourth temperature sensor 450 are all electrically connected to the control unit 410. The control unit 410 is used to adjust the first power supply signal, the second power supply signal and the third power supply signal according to the real-time temperature feedback from the first temperature sensor 420, the second temperature sensor 430, the third temperature sensor 440 and the fourth temperature sensor 450, so as to correspondingly control the heating power of the first heating circuit and the second heating circuit for the discharge pipe 100 and control the heating power of the heating structure 240 for the compensation heat-conducting structure 230.

[0076] A first temperature sensor 420 is disposed on the first electrode sheet 211. The first temperature sensor 420 is used to collect a first real-time temperature of the first electrode sheet 211. The first temperature sensor 420 is electrically connected to the control unit 410 to transmit the first real-time temperature to the control unit 410. A second temperature sensor 430 is disposed on the second electrode sheet 221. The second temperature sensor 430 is used to collect a second real-time temperature of the second electrode sheet 221. The second temperature sensor 430 is electrically connected to the control unit 410 to transmit the second real-time temperature to the control unit 410. A third temperature sensor 440 is disposed on the compensation electrode sheet 231. When multiple compensation electrode sheets 231 are provided, each compensation electrode sheet 231 is provided with a third temperature sensor 440. The third temperature sensor 440 is used to collect a third real-time temperature of the corresponding compensation electrode sheet 231. The third temperature sensor 440 is electrically connected to the control unit 410 to transmit the third real-time temperature to the control unit 410. The fourth temperature sensor 450 is arranged on the discharge pipe 100, and when multiple heating sections are formed on the discharge pipe 100, each heating section is provided with a fourth temperature sensor 450. The fourth temperature sensor 450 is used to collect the fourth real-time temperature of each corresponding heating section. The fourth temperature sensor 450 is electrically connected to the control unit 410 to transmit the fourth real-time temperature to the control unit 410.

[0077] The control unit 410 is used to determine whether the real-time temperatures of the corresponding first electrode sheet 211, the second electrode sheet 221, the compensation electrode sheet 231 and the heating section are consistent based on the first real-time temperature feedback from the first temperature sensor 420, the second real-time temperature feedback from the second temperature sensor 430, the third real-time temperature feedback from the third temperature sensor 440 and the fourth real-time temperature feedback from the fourth temperature sensor 450. When the real-time temperatures of the first electrode sheet 211, the second electrode sheet 221, the compensation electrode sheet 231 and the heating section are inconsistent, the temperature control unit can use a PID (Proportional-Integral-Derivative) control algorithm based on the deviation between the real-time temperature and the preset temperature to determine the heating power that needs to be adjusted for each heating circuit, and then adjust the current or voltage output by the power module 300 according to the heating power, so as to correspondingly control the heating power of each heating circuit for the discharge pipe 100 and control the heating power of the heating structure 240 for the compensation heat-conducting structure 230, to ensure that the temperature of the discharge pipe 100 and each electrode sheet is always maintained within the set range.

[0078] In one embodiment, please refer to Figure 7 and Figure 8 The glass discharging device also includes a heat preservation mechanism 500, which can be detachably arranged on the outer periphery of the discharging pipe 100 and wrap the discharging pipe 100. During the discharging process, the heat preservation mechanism 500 can be used to insulate the discharging pipe 100 to reduce the heat loss of the discharging pipe 100. On the one hand, it can ensure the temperature stability of various parts of the discharging pipe 100, so that the glass liquid flowing through the discharging pipe 100 can be stably heated to ensure the effect of preventing crystallization; on the other hand, the heat loss on the discharging pipe 100 is reduced, which can reduce the required power generation power, which is conducive to reducing energy consumption and thus reducing the cost of discharging. The heat preservation mechanism 500 is detachably arranged on the discharging pipe 100, so that it is convenient to replace the appropriate heat preservation mechanism 500 according to different discharging environments and working conditions, such as replacing the heat preservation mechanism 500 of different thickness and material, etc. At the same time, it is also convenient to clean the heat preservation mechanism 500 separately to ensure the heat preservation performance of the heat preservation mechanism 500. In specific implementation, the heat preservation mechanism 500 can be detachably connected to the discharge pipe 100 by means of elastic metal clips or threaded connections, or it can be directly sleeved on the outer periphery of the discharge pipe 100 to facilitate the disassembly of the heat preservation mechanism 500.

[0079] The insulation mechanism 500 includes multiple layers of insulation layers, which are stacked along the radial direction of the discharge pipe 100 in a direction away from the discharge pipe 100, and the temperature difference between the outermost insulation layer and the discharge pipe 100 floats within a preset range. For example, the multiple insulation layers can be a multi-layer structure formed by alternating insulation felt layers and insulation cotton layers, or a multi-layer structure formed by stacking different insulation materials or heat-insulating materials to ensure the insulation effect of the insulation mechanism 500. In specific implementation, taking into account the cost and insulation effect, the insulation layer can be set to 1-6 layers, preferably 4-6 layers, according to different insulation requirements or different insulation materials. In an optional embodiment, each insulation layer can be set independently, that is, according to the actual insulation needs, the appropriate number of insulation layers can be selected to be sleeved on the outer periphery of the discharge pipe 100 to adapt to different environments and working conditions. During discharging, the temperature of the outermost insulation layer can be maintained at 60℃-100℃. Within this temperature range, under normal circumstances, the lower the temperature, the less heat exchange between the insulation layer and the outside world, and the better the insulation effect. But at the same time, the temperature difference between the outermost insulation layer and the discharge pipe 100 needs to be maintained within a certain range. Under normal circumstances, the smaller the temperature difference, the less heat exchange between the insulation layer and the discharge pipe 100. In this way, through the dual constraints on the temperature on the insulation layer, on the one hand, the lower temperature on the insulation layer can reduce the temperature difference between the insulation layer and the outside world. According to the principle of heat conduction, the rate of heat loss can be reduced, which is beneficial to maintaining the stability of the glass liquid temperature and preventing crystallization problems caused by temperature fluctuations; on the other hand, limiting the temperature difference between the insulation layer and the discharge pipe 100 within a certain range can reduce the heat exchange between the insulation layer and the discharge pipe 100, which is beneficial to further reduce the temperature fluctuation on the discharge pipe 100 and ensure stable liquid discharge.

[0080] Based on the same inventive concept, an embodiment of the present application also provides a glass forming device (not shown), which includes a glass forming mold and a glass discharging device of the above embodiment. The discharge end of the discharge pipe 100 is connected to the glass forming mold to transport the glass liquid into the glass forming mold.

[0081] Based on the same inventive concept, the present embodiment also provides a glass forming method, which is applied to the glass forming device of the above embodiment. Figure 9 , the glass forming method comprises the following steps:

[0082] Step 902 : Control the first heat-conducting structure 210 , the second heat-conducting structure 220 and at least one compensation heat-conducting structure 230 to connect with the power module 300 to form multiple heating loops, and heat the discharge pipe 100 to a first temperature through each heating loop.

[0083] Specifically, the control unit 410 can control the power module 300 to output a corresponding power signal based on the set first temperature, thereby energizing each heating circuit, so that the first heat-conducting structure 210, the second heat-conducting structure 220, the at least one compensating heat-conducting structure 230, and the discharge pipe 100 in each heating circuit can generate heat, thereby maintaining the temperature of the discharge pipe 100 at the first temperature. The first temperature is greater than the critical temperature for crystallization of the glass liquid to prevent crystallization of the glass liquid during flow.

[0084] Step 904 : Control the heating structure 240 to connect with the power module 300 , and heat the at least one compensating heat-conducting structure 230 to a second temperature through the heating structure 240 .

[0085] Specifically, the control unit 410 can control the power module 300 to output a corresponding power signal based on the set second temperature, thereby energizing the heating structure 240, so that the heating structure 240 can generate heat and transfer it to the compensating heat-conducting structure 230, so that the temperature of the compensating heat-conducting structure 230 is maintained at the second temperature. The second temperature is greater than or equal to the first temperature to prevent crystallization of the glass liquid at the contact point between the compensating heat-conducting structure 230 and the discharge pipe 100.

[0086] Step 906 , controlling the molten glass to flow into the discharge pipe 100 along the feed end of the discharge pipe 100 , and then flow into the glass forming mold through the discharge end, so as to be formed by the glass forming mold.

[0087] Specifically, the molten glass liquid can be transported to the glass forming mold by a pressure pump or a suction device to form the glass.

[0088] The use of the glass forming device and forming method of the above-mentioned embodiment to form optical glass can significantly reduce the crystallization phenomenon on the discharge pipe 100 and significantly reduce the residual particulate matter caused by crystallization in the discharge pipe 100. As a result, the time interval for cleaning the discharge pipe 100 is extended from the original 4 hours to 10 hours, which is beneficial to improving the continuous operation time of the glass forming device and improving the glass forming efficiency. At the same time, the fluctuation range of the glass liquid flow rate is reduced from ±10% to ±2%, and the yield rate is increased from 60% to 80%, which is beneficial to improving the forming quality of the glass. It should be understood that although the various steps in the flowchart of the accompanying drawings are displayed in sequence as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.

These steps or stages are not necessarily performed at the same time, but can be performed at different times.
