Their primary function is to melt glass powder into high-quality molten glass, which is then processed through other processes to form substrate glass.

[0003] From the clarification zone to the pre-melting zone of the kiln, the degree of melting of the glass liquid decreases successively, and the resistivity of the glass liquid is increasingly affected by the cold glass material. However, with the increase of the lead-out amount, the feed amount also increases accordingly, and the fluctuation of the resistivity of the glass liquid will become more and more obvious, which will cause fluctuations in the melting process of the electrode in the pre-melting zone, and even cause the electrodes in this area to be unable to be powered, that is, a "power failure" phenomenon occurs, which seriously affects the stability of the kiln operation and product quality.

Modes for Carrying Out the Invention

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] The present invention is described in further detail below with reference to the accompanying drawings:

[0030] Referring to FIG1 , the present invention discloses a front-zone dual-electrode non-uniformly spaced furnace for efficient melting at high flow rates. The furnace comprises a tank wall 1, which encloses a clarification zone 8, a homogenization zone 7, and a plurality of pre-melting zones 6. The pre-melting zone 6 is connected to the homogenization zone 7, which in turn is connected to the clarification zone 8. The pre-melting zone 6 is a location for pre-melting glass powder, used for pre-melting the glass powder. The homogenization zone 7 is used for fully mixing and homogenizing the molten glass. The clarification zone 8 is used for pre-clarification of the molten glass. The total width of the pre-melting zone 6 is greater than the widths of the clarification zone 8 and the homogenization zone 7. A plurality of electrodes 2 are arranged on the tank wall 1 on both sides of the clarification zone 8, the homogenization zone 7, and the pre-melting zone 6. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. The non-uniformly spaced design of the furnace reduces the spacing between the electrodes in the pre-melting zone, thereby facilitating the stability of the furnace electrode power-up process, reducing the risk of fluctuations in the electrode power-up process or even power-up failure due to fluctuations in the resistivity of the molten glass, and reducing the occurrence of "power-down" phenomena. The tank wall 1 is provided with a discharge port 5 and several feed ports 4. The feed ports 4 communicate with the pre-melting zone 6, and the discharge port 5 communicates with the clarification zone 8. Glass powder fed from different feed ports enters the corresponding pre-melting zone for pre-melting. This separates the glass powder fed from different feed ports, preventing interference between the melting processes of the different feed ports during the pre-melting process. This facilitates precise control and regulation of the feed mountain, improving the efficient melting of glass powder at high flow rates. This invention ensures efficient melting of molten glass at high flow rates, stabilizes furnace operation, and reduces the occurrence of "power outages."

[0031] Referring to FIG1 , another feasible embodiment of the present invention, with the following modifications adapted to the circumstances, comprises a pool wall 1, which encloses a clarification zone 8, a homogenization zone 7, and a plurality of pre-melting zones 6. The pre-melting zone 6 is connected to the homogenization zone 7, which is connected to the clarification zone 8. The total width of the pre-melting zone 6 is greater than the widths of the clarification zone 8 and the homogenization zone 7. A plurality of electrodes 2 are arranged on the pool wall 1 on both sides of the clarification zone 8, the homogenization zone 7, and the pre-melting zone 6. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. A discharge port 5 and a plurality of feeding ports 4 are provided on the pool wall 1. The feeding port 4 is connected to the pre-melting zone 6, and the discharge port 5 is connected to the clarification zone 8.

[0032] In specific operation, glass powder fed through different feeding ports enters the corresponding pre-melting zone for pre-melting. The glass powder fed through different feeding ports is separated to avoid mutual interference in the melting process of the materials from different feeding ports during the pre-melting process. The glass powder is pre-melted with electrodes 2 to form glass liquid. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. By reducing the electrode spacing in the pre-melting zone, it is beneficial to the stability of the electrode power-on process of the kiln, reducing the risk of fluctuations in the electrode power-on process or even failure to power on due to fluctuations in the resistivity of the glass liquid, and reducing the occurrence of "power-off" phenomena. The glass liquid enters the homogenization zone 7 from the pre-melting zone 6, is fully mixed and homogenized, and then enters the clarification zone 8 for pre-clarification. After pre-clarification is completed, it flows out through the discharge port 5. The total width of the pre-melting zone 6 is larger than the width of the clarification zone 8 and the homogenization zone 7. The non-uniform spacing design of the kiln further reduces the risk of fluctuations in the electrode power-on process or even failure to power on due to fluctuations in the resistivity of the glass liquid.

[0034] Referring to Figure 1, this embodiment discloses a front-zone double-electrode non-equidistant kiln with efficient melting at a large flow rate, including a pool wall 1, which encloses a clarification zone 8, a homogenization zone 7 and several pre-melting zones 6. The pre-melting zone 6 is connected to the homogenization zone 7, and the homogenization zone 7 is connected to the clarification zone 8. The total width of the pre-melting zone 6 is greater than the widths of the clarification zone 8 and the homogenization zone 7. Several electrodes 2 are arranged on the pool wall 1 on both sides of the clarification zone 8, the homogenization zone 7 and the pre-melting zone 6. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. A discharge port 5 and several feeding ports 4 are opened on the pool wall 1. The feeding port 4 is connected to the pre-melting zone 6, and the discharge port 5 is connected to the clarification zone 8.

[0035] Between the pre-melting zone 6 and the homogenizing zone 7 is the transition zone 3. The transition zone 3 isolates the pre-melting zone from the homogenizing zone, avoiding process interference between the pre-melting zone and the homogenizing zone. This design facilitates precise control and regulation of the material mountain during the process, improving the efficient melting of glass powder at high flow rates.

[0036] The electrodes 2 on both sides of the pre-melting zone 6 are arranged at equal intervals.

[0037] The distance between the electrodes 2 on both sides of the pre-melting zone 6 is 1050 mm to 1100 mm.

The pre-melting zone 6 is connected to the homogenization zone 7, and the homogenization zone 7 is connected to the clarification zone 8. The total width of the pre-melting zone 6 is greater than the widths of the clarification zone 8 and the homogenization zone 7. Several electrodes 2 are arranged on the pool wall 1 on both sides of the clarification zone 8, the homogenization zone 7 and the pre-melting zone 6. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. A discharge port 5 and several feeding ports 4 are opened on the pool wall 1. The feeding port 4 is connected to the pre-melting zone 6, and the discharge port 5 is connected to the clarification zone 8.

[0040] The widths of the clarification zone 8 and the homogenization zone 7 are equal.

[0041] The electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7 are arranged at equal intervals.

[0042] The distance between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7 is 2100 mm to 2200 mm.

[0043] Example 3:

[0044] Referring to Figure 1, this embodiment discloses a front-zone double-electrode non-equidistant kiln with efficient melting at a large flow rate, including a pool wall 1, which encloses a clarification zone 8, a homogenization zone 7 and several pre-melting zones 6. The pre-melting zone 6 is connected to the homogenization zone 7, and the homogenization zone 7 is connected to the clarification zone 8. The total width of the pre-melting zone 6 is greater than the widths of the clarification zone 8 and the homogenization zone 7. Several electrodes 2 are arranged on the pool wall 1 on both sides of the clarification zone 8, the homogenization zone 7 and the pre-melting zone 6. The spacing between the electrodes 2 on both sides of the pre-melting zone 6 is smaller than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. A discharge port 5 and several feeding ports 4 are opened on the pool wall 1. The feeding port 4 is connected to the pre-melting zone 6, and the discharge port 5 is connected to the clarification zone 8.

[0045] 3 , a breast wall 9 is provided on the pool wall 1 , and a crown is arranged on the breast wall 9 .

[0046] 2 and 3 , a plurality of burners 10 are arranged on the breast wall 9 , and the angles of the burners 10 are adjustable.

[0047] Example 4:

[0048] 1 , this embodiment discloses a front zone double-electrode non-equidistant kiln for efficient melting at large flow rates, comprising a pool wall 1 and electrodes 2, which form a closed area; a feeding port 4 and a discharging port 5 are provided at the front and rear of the kiln.

[0049] The closed area of ​​the kiln is divided into three functional areas, namely the pre-melting zone 6, the homogenizing zone 7 and the clarification zone 8. The pre-melting zone 6 is divided into the left pre-melting zone 6-1 and the right pre-melting zone 6-2. The transition area between the pre-melting zone 6 and the homogenizing zone 7 is the transition pool wall.

[0050] The transition pool wall between the pre-melting zone 6 and the homogenizing zone 7 includes an outer transition pool wall 1-1 and an inner transition pool wall 1-2. The inner surfaces of the outer transition pool wall 1-1 and the inner transition pool wall 1-2 are parallel to each other, and the corner connection area with the pool wall 1 is chamfered.

[0051] The width of the pre-melting zone 6 is greater than that of the homogenizing zone 7 and the clarification zone 8, and the electrode spacing in the pre-melting zone 6 is smaller than that in the homogenizing zone 7. The electrode spacing in the homogenizing zone 7 is equal to that in the clarification zone 8. The electrode spacing in the pre-melting zone 6 is 1050mm to 1100mm; the electrode spacing in the homogenizing zone 7 and the clarification zone 8 is 2100mm to 2200mm.

[0052] The kiln electrodes 2 are evenly spaced in the length direction of the kiln, and the number of electrode pairs in each functional zone, i.e., the pre-melting zone 6, the homogenizing zone 7 and the clarification zone 8, is greater than or equal to 2 pairs;

[0053] 2 and 3 , a corresponding burner 10 is provided at the breast wall 9 on the top of each pair of electrodes 2 , and the angle of the burner 10 is adjustable.

[0054] In the kiln structure of the present invention, the front area of ​​the kiln adopts a double-electrode design, that is, a double pre-melting zone 6 design. Glass powder fed from different feeding ports enters the corresponding pre-melting zone for pre-melting. This design separates the glass powder fed from different feeding ports, avoiding mutual interference in the melting process of the material mountains from different feeding ports during the pre-melting process; at the same time, the pre-melting zone and the homogenizing zone are separated by the transition zone 3, avoiding process interference between the pre-melting zone and the homogenizing zone; this design is conducive to achieving precise control and adjustment of the process on the material mountain, and improving the efficient melting of glass powder under large flow rate.

[0055] The kiln structure of the present invention adopts a non-uniform spacing design, that is, the width of the pre-melting zone is greater than the width of the kiln in the homogenizing zone and the clarification zone, and the electrode spacing in the pre-melting zone is smaller than the electrode spacing in the homogenizing zone and the clarification zone; because the degree of melting of the glass liquid decreases successively from the clarification zone to the pre-melting zone of the kiln, and the resistivity of the glass liquid is increasingly affected by the cold glass material, it can be seen that if the electrode distance in the pre-melting zone is too large, the risk of fluctuation in the resistivity of the glass liquid will increase, thereby causing fluctuations in the melting process of the electrodes in the pre-melting zone. The present invention reduces the electrode spacing in the pre-melting zone through the non-uniform spacing design of the kiln, which is beneficial to the stability of the operation of the kiln electrode power-on process and reduces the risk of fluctuations in the electrode power-on process or even failure to power on due to fluctuations in the resistivity of the glass liquid.

[0056] The present invention realizes efficient melting of glass liquid at large flow rate and stable operation of the furnace by designing double electrodes and non-uniform spacing in the front zone of the furnace, combined with a dual-electric hybrid heating method in the pre-melting zone of the furnace.

[0057] Based on the above structure, the present invention discloses a method for operating a front zone dual-electrode non-equidistant kiln with high efficiency melting at a large flow rate, as shown in FIG4 , comprising the following steps:

[0058] S1. Glass powder is fed into the pre-melting zone 6 through the feeding port 4, and the glass powder is pre-melted with the electrode 2 to form a glass liquid;

[0059] S2. The glass liquid enters the homogenizing zone 7 from the pre-melting zone 6, is fully mixed and homogenized, and then enters the clarification zone 8 for pre-clarification. After the pre-clarification is completed, it flows out through the discharge port 5.

[0060] Referring to Figure 4, in another feasible embodiment of the present invention, the following is adaptively modified according to circumstances. Glass powder is fed into the pre-melting zone 6 through the feeding port 4, and the glass powder fed from different feeding ports is separated to avoid mutual interference in the melting process of the materials from different feeding ports during the pre-melting process. The glass powder is pre-melted with an electrode 2 to form a glass liquid. The glass liquid enters the homogenizing zone 7 from the pre-melting zone 6, and after being fully mixed and homogenized, it enters the clarification zone 8 for pre-clarification, and flows out through the discharge port 5 after the pre-clarification is completed. By reducing the electrode spacing in the pre-melting zone and the non-uniform spacing design of the kiln, the stability of the kiln electrode power-on process is improved, and the risk of fluctuations in the electrode power-on process or even failure to power on due to fluctuations in the resistivity of the glass liquid is reduced. The method of the present invention ensures the efficient melting of the glass liquid at a large flow rate and the stability of the kiln operation, and reduces the occurrence of the "power-off" phenomenon.

[0061] Embodiment 5:

[0062] This embodiment discloses a method for operating a front zone dual-electrode non-equidistant kiln with high efficiency melting at high flow rate, comprising the following steps:

[0063] Step 1: The glass powder fed from the left feeding port 4-1 and the right feeding port 4-2 enters the left pre-melting zone 6-1 and the right pre-melting zone 6-2 respectively, and is pre-melted under the mixed heating conditions of the electrode 2 and the burner 10;

[0064] Step 2: The glass liquid that has been pre-melted in the left pre-melting zone 6-1 and the right pre-melting zone 6-2 enters the homogenizing zone 7 under the action of the outer transition pool wall 1-1 and the inner transition pool wall 1-2 to ensure that the glass liquid is fully mixed and homogenized;

[0065] Step 3: The fully mixed and homogenized glass liquid enters the clarification zone 8 for pre-clarification, and flows out through the discharge port 5 after the pre-clarification is completed;

[0066] The above content is only for explaining the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the claims of the present invention.
