Description

Technical Field

[0001] The present invention belongs to the field of substrate glass manufacturing, and relates to a pre-zone double-electrode non-uniform furnace capable of realizing high-efficiency melting under a large flow rate and an operating method thereof.

Background Art

[0002] A glass furnace is an essential melting device in the glass manufacturing industry and is one of the most important and main facilities in the production process of substrate glass. Its main role is to melt glass powder into high-quality glass liquid, and then form it into substrate glass in other processes. In the furnace, as the glass liquid moves from the clarification zone to the pre-melting zone, the solubility of the glass liquid gradually decreases, and the electrical resistivity of the glass liquid increases due to the influence of glass cullet. However, as the withdrawal amount (extraction amount) increases, the input amount also increases, so the fluctuation of the electrical resistivity of the glass liquid becomes significant, the electrode melting process in the pre-melting zone becomes unstable, the electrodes in this area cannot be energized, and a "power cut" phenomenon occurs, which may have a serious impact on the operation stability of the furnace and the product quality.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The solubility of the glass liquid from the clarification zone to the pre-melting zone decreases step by step, and the electrical resistivity of the glass liquid increases due to the influence of glass cullet. On the other hand, as the withdrawal amount increases, the input amount also increases, and the fluctuation of the electrical resistivity of the glass liquid becomes more significant. As a result, the electrode melting process in the pre-melting zone becomes unstable, and in some cases, a "power cut" phenomenon occurs where the electrodes in this area cannot be energized, which has a profound impact on the operation stability of the furnace and the product quality.

[0017] To make the technical solutions of the present invention more easily understandable to those skilled in the art, the technical means of the embodiments of the present invention will be described clearly and completely below with reference to the drawings of the embodiments. It is clear that the embodiments described are only a selection of embodiments of the present invention, and not all embodiments. All other embodiments that can be obtained by those skilled in the art without creative work based on the embodiments of the present invention are also within the scope of the protection of the present invention.

[0018] Furthermore, terms such as "first," "second," etc., in the specification and claims of the present invention, as well as in the drawings, are used to distinguish similar subjects and do not represent a specific order or sequence. Where appropriate, these terms are interchangeable, and embodiments of the present invention may be carried out in an order different from that described or illustrated herein. In addition, the terms "includes" and "has" and their variations are intended to be non-exclusive inclusions, for example, a process, method, system, product, or apparatus that includes multiple steps or elements may include other steps or elements not explicitly listed, or other steps or elements specific to those processes, methods, products, or apparatus.

[0019] The present invention will be described in further detail below with reference to the drawings.

[0020] The present invention discloses a pre-zone double electrode non-equally spaced furnace that achieves highly efficient dissolution under high flow rates, and as shown in Figure 1, the furnace includes a pool wall 1. The pool wall 1 forms a clarification zone 8, a homogenization zone 7, and a plurality of pre-dissolution zones 6. The pre-dissolution zones 6 are connected to the homogenization zone 7, and the homogenization zone 7 is connected to the clarification zone 8. The pre-dissolution zones 6 are where the pre-dissolution of glass powder takes place and are used for the pre-dissolution of glass powder. The homogenization zone 7 is used for thorough mixing and homogenization of the glass liquid, and the clarification zones 8 are used for pre-clarification of the glass liquid. The total width of the pre-dissolution zones 6 is wider than the width of the clarification zones 8 and homogenization zones 7, and a plurality of electrodes 2 are arranged on the pool walls 1 on both sides of the clarification zones 8, homogenization zones 7, and pre-dissolution zones 6. The spacing between the electrodes 2 on both sides of the pre-dissolution zone 6 is designed to be narrower 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-dissolution zone through the non-equal spacing design of the furnace, the operational stability of the furnace's electrode charging process is improved, reducing the risk of fluctuations in the electrode charging process and power failure due to variations in the electrical resistivity of the glass liquid, and reducing the occurrence of "power outages." The pool wall 1 is provided with an outlet 5 and multiple supply ports 4. The supply ports 4 communicate with the pre-dissolution zone 6, and the outlet 5 communicates with the clarification zone 8. Glass powder introduced from different supply ports is introduced into the corresponding pre-dissolution zone, and pre-dissolution is performed. This separates the glass powder introduced from different supply ports, avoiding mutual interference of the material piles from different supply ports in the pre-dissolution process. This allows for precise control and adjustment of the material piles in the process, enabling highly efficient dissolution of glass powder under high flow rates. This invention ensures highly efficient dissolution of glass liquid under high flow rates and stable operation of the furnace, thereby reducing the occurrence of "power outage" phenomena.

[0021] Referring to FIG. 1, in another embodiment of the present invention, adaptive modifications are made as follows according to the situation. This embodiment includes a pool wall 1, and a clarification zone 8, a homogenization zone 7, and a plurality of preliminary dissolution zones 6 are formed by the pool wall 1. The preliminary dissolution zones 6 communicate with the homogenization zone 7, and the homogenization zone 7 communicates with the clarification zone 8. The total width of the preliminary dissolution zones 6 is wider than the widths of the clarification zone 8 and the homogenization zone 7, and a plurality of electrodes 2 are arranged on both sides of the pool wall 1 of the clarification zone 8, the homogenization zone 7, and the preliminary dissolution zones 6. The distance between the electrodes 2 on both sides of the preliminary dissolution zones 6 is narrower than the distance between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. The pool wall 1 is provided with a discharge port 5 and a plurality of supply ports 4. The supply ports 4 communicate with the preliminary dissolution zones 6, and the discharge port 5 communicates with the clarification zone 8.

[0022] During specific operation, the glass powder introduced from different supply ports is introduced into the corresponding preliminary dissolution zones for preliminary dissolution. By separating the glass powder introduced from different supply ports, the mutual interference of the dissolution processes of the material piles at different supply ports in the preliminary dissolution process is avoided. The preliminary dissolution of the glass powder is carried out using the electrodes 2, and a glass liquid is formed. The distance between the electrodes 2 on both sides of the preliminary dissolution zones 6 is narrower than the distance between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. By reducing the electrode distance in the preliminary dissolution zones, the stability of the electrode energization process of the kiln furnace is improved, the risk of fluctuations in the electrode energization process and power failure due to fluctuations in the electrical resistivity of the glass liquid is reduced, and the occurrence of the "power cut-off" phenomenon is suppressed. The glass liquid enters the homogenization zone 7 from the preliminary dissolution zones 6, is sufficiently mixed and homogenized, then enters the clarification zone 8 for preliminary clarification, and flows out from the discharge port 5 when the preliminary clarification is completed. The total width of the preliminary dissolution zones 6 is wider than the widths of the clarification zone 8 and the homogenization zone 7. Due to the non-uniform interval design of the kiln furnace, the risk of fluctuations in the electrode energization process and power failure caused by fluctuations in the electrical resistivity of the glass liquid is further reduced.

[0023] (Example 1) Referring to FIG. 1, this embodiment discloses a pre-zone double electrode non-uniform spacing furnace that realizes high-efficiency melting under a large flow rate. The furnace includes a pool wall 1, and the pool wall 1 forms a clarification zone 8, a homogenization zone 7, and a plurality of preliminary melting zones 6. The preliminary melting zones 6 communicate with the homogenization zone 7, and the homogenization zone 7 communicates with the clarification zone 8. The total width of the preliminary melting zones 6 is wider than the widths of the clarification zone 8 and the homogenization zone 7, and a plurality of electrodes 2 are arranged on the pool walls 1 on both sides of the clarification zone 8, the homogenization zone 7, and the preliminary melting zones 6. The spacing between the electrodes 2 on both sides of the preliminary melting zones 6 is narrower than the spacing between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. The pool wall 1 is provided with a discharge port 5 and a plurality of supply ports 4. The supply ports 4 communicate with the preliminary melting zones 6, and the discharge port 5 communicates with the clarification zone 8.

[0024] A transition zone 3 is provided between the preliminary melting zones 6 and the homogenization zone 7. The transition zone 3 separates the preliminary melting zone and the homogenization zone, and avoids interference in the industrial process between the preliminary melting zones 6 and the homogenization zone 7 (between both zones). This design helps to precisely control and adjust the material pile during the process, and improves the high-efficiency melting of glass powder under a large flow rate.

[0025] The electrodes 2 on both sides of the preliminary melting zones 6 are arranged at equal intervals, and the spacing between the electrodes 2 on both sides of the preliminary melting zones 6 is 1050 mm to 1100 mm.

[0026] (Example 2) Referring to Figure 1, this embodiment discloses a pre-zone double electrode non-equally spaced furnace that achieves highly efficient dissolution under high flow rates. The furnace includes a pool wall 1, which forms a clarification zone 8, a homogenization zone 7, and a plurality of pre-dissolution zones 6. The pre-dissolution zones 6 communicate with the homogenization zone 7, and the homogenization zone 7 communicates with the clarification zone 8. The total width of the pre-dissolution zones 6 is wider than the width of the clarification zones 8 and the homogenization zones 7, and a plurality of electrodes 2 are arranged on the pool walls 1 on both sides of the clarification zones 8, the homogenization zones 7, and the pre-dissolution zones 6. The spacing between the electrodes 2 on both sides of the pre-dissolution zones 6 is narrower than the spacing between the electrodes 2 on both sides of the clarification zones 8 and the homogenization zones 7. The pool wall 1 is provided with an outlet 5 and a plurality of supply ports 4, the supply ports 4 communicate with the pre-dissolution zones 6, and the outlet 5 communicates with the clarification zone 8.

[0027] The widths of the clarification zone 8 and the homogenization zone 7 are equal. The electrodes 2 positioned on both sides of the clarification zone 8 and the homogenization zone 7 are equally spaced, and the spacing between the electrodes 2 positioned on both sides of the clarification zone 8 and the homogenization zone 7 is between 2100 mm and 2200 mm.

[0028] (Example 3) Referring to Figure 1, this embodiment discloses a pre-zone double electrode non-equally spaced furnace that achieves highly efficient dissolution under high flow rates. The furnace includes a pool wall 1, which forms a clarification zone 8, a homogenization zone 7, and a plurality of pre-dissolution zones 6. The pre-dissolution zones 6 communicate with the homogenization zone 7, and the homogenization zone 7 communicates with the clarification zone 8. The total width of the pre-dissolution zones 6 is wider than the width of the clarification zones 8 and the homogenization zones 7, and a plurality of electrodes 2 are arranged on the pool walls 1 on both sides of the clarification zones 8, the homogenization zones 7, and the pre-dissolution zones 6. The spacing between the electrodes 2 on both sides of the pre-dissolution zones 6 is narrower than the spacing between the electrodes 2 on both sides of the clarification zones 8 and the homogenization zones 7. The pool wall 1 is provided with an outlet 5 and a plurality of supply ports 4, the supply ports 4 communicate with the pre-dissolution zones 6, and the outlet 5 communicates with the clarification zone 8.

[0029] Referring to Figure 3, the pool wall 1 is equipped with a parapet 9, and an arched ceiling is positioned above the parapet 9.

[0030] Referring to Figures 2 and 3, multiple burning guns 10 are positioned on the chest wall 9, and the angles of the burning guns 10 are adjustable.

[0031] (Example 4) Referring to Figure 1, this embodiment discloses a front-zone double-electrode non-equally spaced furnace that achieves highly efficient melting under high flow rates. The furnace includes a pool wall 1 and electrodes 2, with the pool wall 1 and electrodes 2 forming a single sealed region. A supply port 4 and an outlet port 5 are provided at the front and rear of the furnace.

[0032] The sealed area of ​​the furnace is divided into three functional zones (regions): a pre-melting zone 6, a homogenization zone 7, and a clarification zone 8. The pre-melting zone 6 is further divided into the left pre-melting zone 6-1 and the right pre-melting zone 6-2. A transition pool wall is provided between the pre-melting zone 6 and the homogenization zone 7.

[0033] The transition pool walls of the pre-dissolution zone 6 and the homogenization zone 7 include 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 connections of pool wall 1 are chamfered.

[0034] The furnace width of pre-dissolution zone 6 is wider than that of homogenization zone 7 and clarification zone 8, and the electrode spacing in pre-dissolution zone 6 is narrower than that of homogenization zone 7. The electrode spacing in homogenization zone 7 and clarification zone 8 is equal, and the electrode spacing in pre-dissolution zone 6 is 1050 mm to 1100 mm. The electrode spacing in homogenization zone 7 and clarification zone 8 is 2100 mm to 2200 mm.

[0035] The electrodes 2 of the furnace are arranged at equal intervals along the length of the furnace, and at least two pairs of electrodes are provided for each functional zone, namely the pre-dissolution zone 6, the homogenization zone 7, and the clarification zone 8.

[0036] Referring to Figures 2 and 3, a corresponding burning gun 10 is provided on the upper chest wall 9 of each pair of electrodes 2, and the angle of the burning gun 10 is adjustable.

[0037] In the furnace structure of the present invention, a double electrode design is adopted in the front zone (front region) of the furnace, specifically a double pre-melting zone 6 design. Glass powder fed from different feed ports is pre-melted in the corresponding pre-melting zone. This design separates the glass powder fed from different feed ports, preventing interference between the melting processes of material piles from different feed ports during the pre-melting process. At the same time, the transition zone 3 separates the pre-melting zone and the homogenization zone, preventing process interference between the pre-melting zone and the homogenization zone. This design facilitates precise control and adjustment of the material pile during the process, improving the highly efficient melting of glass powder at high flow rates.

[0038] In the furnace structure of the present invention, an unequal spacing design is adopted for the furnace, where the furnace width in the pre-melting zone is wider than that of the homogenization and clarification zones, and the electrode spacing in the pre-melting zone is narrower than that of the homogenization and clarification zones. This is because the solubility of the glass liquid decreases stepwise from the clarification zone to the pre-melting zone of the furnace, and the influence of the glass liquid's electrical resistivity on the glass coolant increases. If the electrode spacing in the pre-melting zone is too wide, the risk of fluctuations in the glass liquid's electrical resistivity increases, which can cause fluctuations in the electrode melting process in the pre-melting zone. The present invention reduces the electrode spacing in the pre-melting zone through an unequal spacing design of the furnace, thereby improving the operational stability of the furnace's electrode charging process and reducing the risk of fluctuations in the electrode charging process or failure to energize due to fluctuations in the glass liquid's electrical resistivity.

[0039] This invention employs a double electrode and non-equally spaced design in the furnace pre-melting zone, and further combines this with a dual electric hybrid heating system in the furnace pre-melting zone to achieve highly efficient melting of glass liquid under high flow rates and stable furnace operation.

[0040] Based on the above structure, the present invention discloses an operating method for a pre-zone double electrode non-equally spaced furnace that performs highly efficient melting under high flow rates. Referring to Figure 4, the method includes the following steps.

[0041] Step S1: Glass powder is introduced into the pre-dissolution zone 6 from the supply port 4, and the glass powder is pre-dissolved using the electrode 2 to form a glass liquid.

[0042] Step S2: The glass liquid moves from the pre-dissolution zone 6 to the homogenization zone 7, where it is thoroughly mixed and homogenized before entering the clarification zone 8, where preliminary clarification is performed. Once preliminary clarification is complete, the liquid flows out through outlet 5.

[0043] As shown in Figure 4, in other embodiments of the present invention, adaptive modifications can be made depending on the situation. Glass powder can be fed from the supply port 4 to the pre-melting zone 6, and glass powder fed from different supply ports can be separated to avoid mutual interference of the melting processes of material piles from different supply ports in the pre-melting process. The glass powder is pre-melted using electrodes 2 to form a glass liquid. The glass liquid moves from the pre-melting zone 6 to the homogenization zone 7, and after being thoroughly mixed and homogenized, proceeds to the clarification zone 8, where pre-clarification is performed, and when pre-clarification is complete, it flows out from the outlet 5. By reducing the electrode spacing in the pre-melting zone and designing the furnace with uneven spacing, the operational stability of the electrode charging process in the furnace can be improved, and the risk of fluctuations in the electrode charging process or failure to energize due to fluctuations in the electrical resistivity of the glass liquid can be reduced. The method of the present invention can ensure highly efficient melting of the glass liquid and stability of furnace operation under high flow rates, and can reduce the occurrence of "power outage" phenomena.

[0044] (Example 5) This embodiment discloses a method for operating a pre-zone double electrode non-equally spaced furnace that performs highly efficient melting under high flow rates, and includes the following steps.

[0045] Step 1: The glass powder fed in from the left supply port 4-1 and the right supply port 4-2 enters the left pre-melting zone 6-1 and the right pre-melting zone 6-2, respectively, and pre-melting is performed under mixed heating conditions by electrode 2 and burning gun 10.

[0046] Step 2: The glass liquid, which has completed pre-dissolution in the left pre-dissolution zone 6-1 and the right pre-dissolution zone 6-2, moves to the homogenization zone 7 through the outer migration pool wall 1-1 and the inner migration pool wall 1-2, ensuring that the glass liquid is thoroughly mixed and homogenized.

[0047] Step 3: The thoroughly mixed and homogenized glass liquid enters the clarification zone 8, where preliminary clarification is performed. Once preliminary clarification is complete, the liquid flows out through outlet 5.

[0048] The foregoing are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Those skilled in the art can make simple modifications and substitutions to the technical solutions of the present invention without departing from the spirit and principles of the present invention, and such modifications and substitutions are within the scope of the protection covered by the claims of the present invention.
