Description

Technical Field

[0001] The present disclosure relates to the technical field of glass production, and in particular to a temperature compensation device for glass substrate molding. Background Art

[0002] In the glass substrate forming process produced by the overflow down-draw method, the glass liquid flows through the tip of the overflow brick of the muffle furnace, and the glass ribbon is clamped by the edge drawing machine to start the board production. The overflow of the glass liquid and the convergence effect here are important factors affecting production. Whether it can be normal and stable is also an important factor affecting the subsequent quality adjustment. The convergence state of the convergence plate is determined by many factors, among which temperature is the most important indicator.

[0003] After long-term production, the overflow brick tip ages, resulting in insufficient temperature and poor convergence, making it difficult to adjust the molding quality of the glass substrate or even impossible to guide the board. Since the temperature in the muffle furnace is already very high, the heat of ordinary heaters is difficult to improve the aging of the overflow brick convergence plate. How to improve the overflow brick convergence plate condition and extend the operating cycle of the molding process is a key problem.

[0004] In the published patent CN201511022751.4, it is mentioned that a heater is used to solve the problem of crystallization of the convergence plate. However, the use of the invented heater still cannot solve the problem of improving the convergence state. Utility Model Content

[0009] A heating assembly, the heating assembly comprising a burner brick having a flame channel and a burner gun arranged toward the entrance of the flame channel;

[0010] The fire head brick can be inserted into the opening and guide the flame sprayed from the burner toward the brick tip of the overflow brick.

[0011] In some embodiments, the opening is arranged on the lower side of the overflow brick, and an outlet is arranged on the top of one end of the fire head brick inserted into the muffle furnace.

[0036] This solution provides a temperature compensation device for glass substrate molding, which includes:

[0037] A muffle furnace 7, wherein an opening is provided at an end of the muffle furnace 7;

[0038] an overflow brick 8 and a manifold 81 connected to the overflow brick 8, wherein the overflow brick 8 and the manifold 81 are arranged in the muffle furnace 7; and

[0039] A heating assembly, the heating assembly comprises a fire head brick 5 having a flame channel and a burner 6 arranged toward the entrance of the flame channel;

[0040] The fire head brick 5 can be inserted into the opening and guide the flame sprayed from the burner 6 to spray toward the brick tip of the overflow brick 8.

[0041] The muffle furnace 7 is used to accommodate the overflow brick 8 and the manifold 81 at the end of the overflow brick 8. An opening is provided at the end of the muffle furnace 7 to allow the fire head brick 5 to be inserted into the muffle furnace 7. An openable and closable door can be provided at the opening. When the heating component is not needed, the opening can be closed.

[0042] The heating assembly includes a fire head brick 5 and a burner 6. The burner 6 can spray out high-temperature flames, and the fire head brick 5 can guide the flames to spray toward the manifold 81.

[0043] Among them, a flame channel is arranged inside the fire head brick 5, the burner 6 faces its inlet, and its outlet faces the brick tip of the overflow brick 8, especially the brick tip at the connection position of the overflow brick 8 and the manifold 81.

[0044] During the production process, when the confluence state at the overflow brick 8 and the convergence plate 81 does not meet the production requirements, the opening of the muffle furnace 7 can be opened, the fire head brick 5 of the heating component can be inserted into the opening, and the burner 6 can be turned on to heat the tip of the overflow brick 8 connected to the convergence plate 81 through the burning flame, so that its temperature is increased to improve the confluence state; when the confluence state meets the requirements, the heating can be stopped, the heating component can be removed and the opening of the muffle furnace 7 can be closed.

[0045] In this solution, a burner is used to heat the tip of the overflow brick connecting the overflow brick and the busbar, which can increase the temperature of the overflow brick to improve the convergence state, solving the problem that traditional auxiliary heating cannot increase the temperature of the overflow brick.

[0046] In some embodiments, the opening is arranged on the lower side of the overflow brick 8, and an outlet is arranged on the top of one end of the fire head brick 5 inserted into the muffle furnace 7. Figure 1 As shown, the fire head brick 5 is inserted into the muffle furnace 7 and is located at the lower side of the overflow brick 8. An outlet is provided at the top thereof. The fire head brick 5 guides the flame to spray upward to heat the overflow brick 8. The depth of insertion of the fire head brick 5 makes the outlet face the position where the overflow brick 8 is connected to the manifold 81 to increase the temperature there, thereby improving the confluence state. Generally speaking, in the muffle furnace 7, there is a space for accommodating the fire head brick 5 at the lower side of the overflow brick 8. Therefore, the fire head brick 5 is arranged at such a position, and accordingly, its outlet faces upward.

[0047] In addition, in some embodiments, a horizontal inlet is provided on one end surface of the fire head brick 5 located outside the muffle furnace 7, and the burner 6 extends horizontally and faces the inlet. Figure 1 As shown, the burner 6 is directed toward the inlet of the fire head brick 5 to spray the flame into the flame channel of the fire head brick 5. The flame channel in the fire head brick 5 includes a horizontal part and a vertical part to guide the flame to turn from a horizontal direction to a vertical direction.

[0048] In addition, in some embodiments, the heating assembly includes an upper clamping plate 1 and a lower clamping plate 2 for clamping the fire head brick 5, and a connecting rod 4 connecting the upper clamping plate 1 and the lower clamping plate 2. The fire head brick 5 is clamped between the upper clamping plate 1 and the lower clamping plate 2, and the connecting rod 4 can connect the upper clamping plate 1 and the lower clamping plate 2 together. Among them, the connecting rod 4 can be provided with an external thread and a nut can be screwed, and the nut can be pressed on the upper surface of the upper clamping plate 1 and the lower side of the lower clamping plate 2, so that the upper clamping plate 1 and the lower clamping plate 2 are clamped on the fire head brick 5; or, the upper and lower parts of the connecting rod 4 are respectively provided with external threads with opposite rotation directions, and the upper clamping plate 1 and the lower clamping plate 2 are respectively provided with internal threads with opposite rotation directions. When the connecting rod 4 rotates, the upper clamping plate 1 and the lower clamping plate 2 can be made to move closer or farther from each other to achieve clamping or release. In addition, the connecting rod 4 can also be used as an operating handle to facilitate the installation of the heating assembly to the muffle furnace 7 or its removal.

[0049] In addition, in some embodiments, the heating assembly includes a support member 3 disposed on the lower clamping plate 2, and the burner 6 is disposed on the support member 3. The lower clamping plate 2 is a plate-like structure, and it is inconvenient to directly install the burner, so the support member 3 is disposed thereon to fix and support the burner 6.

[0050] refer to Figure 4 and Figure 5 As shown, the upper clamping plate 1 is formed into a C shape, and the lower clamping plate 2 is formed into a mountain shape. The C-shaped part of the lower clamping plate 2 and the upper clamping plate 1 cooperate with each other to clamp the fire head brick 5, and the support member 3 can be set on the additional strip plate.

[0051] In some embodiments, the support member 3 can move in the height direction relative to the lower clamping plate 2. The movement of the support member 3 relative to the lower clamping plate 2 can adjust the relative height of the burner 6 so that the burner 6 is aligned with the inlet of the fire head brick 5.

[0052] In some embodiments, the support member 3 includes a support rod 31 with an external thread and a nut 33 screwed to the support rod 31, the support rod 31 passes through the lower clamping plate 2, and the nuts 33 are pressed on both sides of the lower clamping plate 2. Two nuts 33 can be screwed on the support rod 31, and the two nuts 33 clamp the lower clamping plate 2 so that the support rod 31 is fixed relative to the lower clamping plate 2. When the relative position of the support rod 31 needs to be adjusted, the two nuts 33 are rotated so that the two nuts 33 are away from each other, and when the support rod 31 is moved to the target position in the vertical direction (for example, so that the burner 6 is aligned with the entrance of the fire head brick 5), the two nuts 33 are rotated again to clamp the lower clamping plate 2.

[0053] In addition, in some embodiments, reference Figure 3 As shown, the support member 3 further includes a support frame 32 connected to the upper end of the support rod 31, and the burner 6 is accommodated in the support frame 32. The support frame 32 can be a C-shape with an opening facing upward to support the burner 6 accommodated therein.

[0054] In addition, in some embodiments, two horizontal sides of the support frame 32 are provided with top screws. The top screws are screwed to the support frame 32, and the two top screws located on the two sides can jointly press the middle burner 6 to fix the burner 6 in the horizontal direction.

[0055] In addition, in some embodiments, the burner 6 is connected with a combustible gas pipe 61 and a combustion-supporting gas pipe 62. The combustible gas pipe 61 can provide acetylene or similar gas, and the combustion-supporting gas pipe 62 can provide oxygen and the like.
