Description

Technical Field

[0001] The utility model relates to the technical field of glass kilns, in particular to a kiln structure with a replaceable electric fluxing method. Background Art

[0002] Glass kilns are built with refractory bricks and are mainly used to melt glass batch materials in the production of glass products. After years of development, the energy input method of glass kilns has evolved from heavy oil combustion in the early days to today's full oxygen combustion method. While the energy density is higher, the pollution generated has also become smaller. In the preparation process of some high-end glass products, a new glass liquid melting method combining electric melting and full oxygen combustion has been introduced.

[0003] The current electric boosting systems for glass furnaces mainly include bottom-plug electric boosting and side-plug electric boosting. Both types of electric boosting have their own advantages and disadvantages. For example, when the length-to-width ratio of the furnace is too large, the electric boosting power will also increase, which accelerates the erosion of the pool wall bricks. The glass liquid flow generated by the bottom-plug electric boosting is difficult to control, and the furnace process requirements are high. Among them, patent publication number CN117142747A discloses an electric heating device and method for a high-generation large-tonnage substrate glass furnace. The electric boosting method with bottom-plug electric boosting as an auxiliary method cannot meet the requirements of using a certain type of electric boosting alone. For this reason, we propose a furnace structure with a replaceable electric boosting method. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a kiln structure with a replaceable electric boosting method. In the early production of the kiln, the side-plug electric boosting method is selected because the erosion degree of the glass kiln pool wall is relatively small. In the later stage, the erosion degree of the glass kiln pool wall increases, and the kiln width is too large, which requires increasing the side-plug electric boosting power. At this time, the bottom-plug molybdenum electrode electric boosting method is adopted. The two sets of electric boosting systems operate independently, saving energy consumption. Different electric boosting systems can be used separately at different times of kiln operation to achieve the purpose of stabilizing the product yield of the entire production line cycle.

[0005] In order to solve the above technical problems, the present invention solves the problem that the kiln only uses one fluxing method, which has obvious disadvantages, through the following technical solutions.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A furnace structure with a replaceable electric boosting method includes a glass furnace pool bottom, a glass furnace pool wall fixedly provided on the top of the glass furnace pool bottom, evenly distributed molybdenum electrodes fixedly provided on the glass furnace pool bottom, a glass furnace discharge port provided on the glass furnace pool bottom, and a side plug electrode fixedly installed on a single side wall of the glass furnace pool wall. The molybdenum electrode and the side plug electrode are respectively controlled by an external controller.

[0008] In some embodiments, there are 15 molybdenum electrodes, with 3 molybdenum electrodes in each group, for a total of 5 groups of molybdenum electrodes. The 5 groups of molybdenum electrodes are respectively arranged on the left and right sides of the bottom of the glass kiln pool to heat and melt the glass liquid in the glass kiln.

[0009] In some embodiments, a plurality of thermocouples are fixedly installed at the bottom of the glass furnace pool to monitor the temperature of various parts in the glass furnace.

[0010] In some embodiments, evenly distributed support columns are fixed on the outside of the glass kiln pool wall, and the bottom of the support columns is fixed to the bottom of the glass kiln pool to support the outside of the glass kiln pool wall to prevent the glass kiln pool wall from tilting due to ablation.

[0011] In some embodiments, evenly distributed wing plates are fixedly provided at the contact portion between the support column and the glass furnace pool wall, thereby increasing the supporting area of the support column on the glass furnace pool wall.

[0012] In some embodiments, the wing plate is fixed to the glass furnace pool wall by fixing bolts, and the fixing effect of the wing plate and the glass furnace pool wall is better.

[0013] In some embodiments, the wing plates and support columns are both made of 316 heat-resistant steel, which improves the high temperature resistance of the fixing bolts, wing plates, and support columns.

[0014] In some embodiments, two of the thermocouples are located outside the glass kiln discharge port, and the remaining thermocouple is located on the left side of the molybdenum electrode area to monitor the temperature at the glass kiln discharge port and the bottom of the leftmost glass kiln pool, control the power of the corresponding molybdenum electrode, form a thermal barrier zone, and prevent the generation of secondary bubbles.

[0015] In some embodiments, the bottom and walls of the glass furnace pool are both made of AZS bricks. AZS bricks with good erosion resistance and scouring performance are selected, and the geometric dimensions of a single brick are minimized to avoid defects such as cracks, thereby improving the durability of the glass furnace pool wall.

[0016] In some embodiments, a silicon dioxide coating is provided on the outside of the molybdenum electrode and the side-insertion electrode to improve the oxidation resistance of the molybdenum electrode and the side-insertion electrode themselves.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the early stage of kiln production, the utility model adopts the side plug electric fluxing method because the erosion degree of the glass kiln pool wall is relatively small. In the later stage, the erosion degree of the glass kiln pool wall increases and the kiln width is too large, which increases the side plug electric fluxing power. At this time, the bottom plug molybdenum electrode electric fluxing method is adopted. The two sets of electric fluxing systems operate independently, saving energy consumption. Different electric fluxing systems can be used separately at different stages of kiln operation to achieve the purpose of stabilizing the product yield of the entire production line cycle.

[0019] By arranging evenly distributed support columns on the outside of the glass kiln pool wall, and arranging multiple wing plates on the support columns, the wing plates are fixed to the outside of the glass kiln pool wall by bolts, and the support columns are used to support the glass kiln pool wall to prevent the glass kiln pool wall from tilting due to ablation.

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or gear element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] Example:

[0033] See also Figures 1-6 A furnace structure with a replaceable electric fluxing method includes a glass furnace pool bottom 1, a glass furnace pool wall 2 is fixedly provided on the top of the glass furnace pool bottom 1, the glass furnace pool bottom 1 is fixedly provided with evenly distributed molybdenum electrodes 3, the glass furnace pool bottom 1 is provided with a glass furnace discharge port 4, and a side plug-in electrode 5 is fixedly installed on the single side pool wall of the glass furnace pool wall 2. The molybdenum electrode 3 and the side plug-in electrode 5 are respectively controlled by an external controller.

[0034] In an embodiment of the present application, 15 molybdenum electrodes 3 are provided, with 3 molybdenum electrodes 3 in each group, and a total of 5 groups of molybdenum electrodes 3 are provided. The 5 groups of molybdenum electrodes 3 are respectively arranged on the left and right sides of the bottom 1 of the glass kiln to heat and melt the glass liquid in the glass kiln.

[0035] In the embodiments of the present application, Figure 2 As shown, a plurality of thermocouples 6 are fixedly provided at the bottom of the glass furnace pool 1 to monitor the temperature conditions of various parts in the glass furnace. Two of the thermocouples 6 are provided outside the glass furnace discharge port 4, and the remaining thermocouple 6 is provided on the left side of the molybdenum electrode 3 area.

[0036] In an embodiment of the present application, evenly distributed support columns 7 are fixed to the outside of the glass kiln pool wall 2, and the bottom of the support columns 7 is fixed to the glass kiln pool bottom 1 to support the outside of the glass kiln pool wall 2 to prevent the glass kiln pool wall 2 from tilting due to ablation. The contact parts of the support columns 7 with the glass kiln pool wall 2 are fixed with evenly distributed wing plates 8 fixed to the inside of the glass kiln pool wall 2 by fixing bolts to increase the supporting area of the support columns 7 on the glass kiln pool wall 2.

[0037] During the implementation process, a silicon dioxide coating is provided on the outside of the molybdenum electrode and the side-inserted electrode to improve the anti-oxidation performance of the molybdenum electrode and the side-inserted electrode itself. In the early production of the kiln, since the erosion degree of the glass kiln pool wall 2 is relatively small, the side-inserted electric melting method is selected. In the later stage, the erosion degree of the glass kiln pool wall 2 increases, and the kiln width is too large, which increases the side-inserted electric melting power. At this time, the bottom-inserted molybdenum electrode 3 electric melting method is adopted. The two sets of electric melting systems operate independently, saving energy consumption. Different electric melting systems can be used separately at different times of the kiln operation to achieve the purpose of stabilizing the product yield of the entire production line cycle.

[0038] By setting two groups of molybdenum electrodes 3 and thermocouples 6 outside the glass kiln discharge port 4, the temperature at the glass kiln discharge port 4 is monitored and judged together with the value monitored by the thermocouple 6 on the left side inside the glass kiln to ensure that the electric melting power of the molybdenum electrode 3 near the glass kiln discharge port 4 is greater than the electric melting power of the molybdenum electrode 3 on the left side inside the glass kiln, forming a thermal barrier zone near the glass kiln discharge port 4 to prevent the generation of secondary bubbles and ensure the color and quality of the discharge material.

[0039] like Figure 3 As shown, evenly distributed support columns 7 are arranged on the outside of the glass furnace pool wall 2, and multiple wing plates 8 are arranged on the support columns 7. The wing plates 8 are fixed to the outside of the glass furnace pool wall 2 by bolts, and the support columns 7 are used to support the glass furnace pool wall 2 to prevent the glass furnace pool wall 2 from tilting due to ablation. The wing plates 8 and the support columns 7 are both made of 316 heat-resistant steel, which improves the high-temperature resistance of the fixing bolts, wing plates 8 and support columns 7.

[0040] At the same time, when stacking the glass furnace pool bottom 1 and the glass furnace pool wall 2, AZS bricks with good erosion resistance and scouring performance are selected, and the geometric size of a single brick is reduced as much as possible to avoid defects such as cracks and improve the durability of the glass furnace pool wall 2 and the glass furnace pool bottom 1.

[0041] In addition, if Figure 2 and Figure 5 As shown, when assembling the molybdenum electrodes 3, the spacing between each group of molybdenum electrodes 3 is required to be greater than the width of each group of molybdenum electrodes 3, and the spacing between each side-inserted electrode 5 should be greater than the width of the side-inserted electrode 5 itself. This can reduce the electromagnetic field interference between adjacent electrodes, ensure that each electrode can work independently and stably, and ensure full utilization of electrical energy. This independence helps to maintain temperature uniformity and stability during the glass melting process, reduce the occurrence of defects such as bubbles and streaks, and thus improve the quality of glass products.

[0042] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
