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-spacing furnace that realizes high-efficiency melting under a large flow rate and a method for operating the same.

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 drawing 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 significant 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 while the electrical resistivity of the glass liquid increases due to the influence of glass cullet, the input amount increases with the increase in the drawing amount, and the fluctuation of the electrical resistivity of the glass liquid becomes even 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 serious impact on the operation stability of the furnace and the product quality.

[0019] Hereinafter, the present invention will be described in more detail based on the drawings.

[0020] The present invention discloses a pre-zone double-electrode non-uniform-spacing furnace that realizes high-efficiency melting under a large flow rate. 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 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 preliminary melting zone 6 is a place for preliminary melting of glass powder and is used for the preliminary melting of glass powder. The homogenization zone 7 is used for sufficient mixing and homogenization of the glass liquid, and the clarification zone 8 is used for preliminary clarification of the glass liquid. The total width of the preliminary melting zones 6 is wider 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 preliminary melting zones 6. The interval between the electrodes 2 on both sides of the preliminary melting zones 6 is designed to be narrower than the interval between the electrodes 2 on both sides of the clarification zone 8 and the homogenization zone 7. By reducing the electrode interval in the preliminary melting zone through the non-uniform-spacing design of the furnace, the operating stability of the electrode energization process of the 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 reduced. 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. The glass powder introduced from different supply ports is introduced into the corresponding preliminary melting zones and undergoes preliminary melting, so that the glass powder introduced from different supply ports is separated, the mutual interference of the melting processes of the material piles at different supply ports in the preliminary melting process is avoided, precise control and adjustment of the material piles in the process are possible, and high-efficiency melting of glass powder under a large flow rate is realized. According to the present invention, high-efficiency melting of the glass liquid under a large flow rate and the operating stability of the furnace are ensured, and the occurrence of the "power cut-off" phenomenon is reduced.

[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 caused by 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 after 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.

[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 the two 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.

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.

[0029] Referring to Fig. 3, a chest wall 9 is provided on the pool wall 1, and an arch-shaped ceiling is arranged above the chest wall 9.

[0030] Referring to Figs. 2 and 3, a plurality of burning guns 10 are arranged on the chest wall 9, and the angle of the burning gun 10 is adjustable.

[0031] (Example 4) Referring to Fig. 1, this embodiment discloses a pre-zone double-electrode non-uniform-spacing kiln furnace that realizes high-efficiency melting under a large flow rate. The kiln furnace includes a pool wall 1 and electrodes 2, and a sealed area is formed by the pool wall 1 and the electrodes 2. A supply port 4 and a discharge port 5 are provided at the front and rear of the kiln furnace.

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

[0033] The transition pool wall between the preliminary melting zone 6 and the homogenization 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 part of the pool wall 1 is chamfered.

[0034] The kiln furnace width of the preliminary melting zone 6 is wider than that of the homogenization zone 7 and the clarification zone 8, and the electrode spacing of the preliminary melting zone 6 is narrower than that of the homogenization zone 7. The electrode spacings of the homogenization zone 7 and the clarification zone 8 are equal, and the electrode spacing of the preliminary melting zone 6 is from 1050 mm to 1100 mm. The electrode spacings of the homogenization zone 7 and the clarification zone 8 are from 2100 mm to 2200 mm.

[0035] The electrodes 2 of the kiln furnace are arranged at equal intervals in the length direction of the kiln furnace, and at least two pairs of electrodes are provided in each functional zone, namely the preliminary melting zone 6, the homogenization zone 7, and the clarification zone 8.

[0036] Referring to FIGS. 2 and 3, corresponding burning guns 10 are 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 area) of the furnace, that is, the design of a double pre-melting zone 6 is adopted. The glass powder fed from different feed ports is pre-melted in the corresponding pre-melting zones. This design separates the glass powder fed from different feed ports and can avoid the melting processes of the material piles at different feed ports interfering with each other in the pre-melting process. At the same time, the transition zone 3 separates the pre-melting zone and the homogenization zone, and the process interference between the pre-melting zone and the homogenization zone can be avoided. This design helps in the precise control and adjustment of the material pile during the process and improves the high-efficiency melting of glass powder under a large flow rate.

[0038] In the furnace structure of the present invention, a non-uniform spacing design is adopted for the furnace. The furnace width of the pre-melting zone is wider than that of the homogenization zone and the clarification zone, and the electrode spacing of the pre-melting zone is narrower than that of the homogenization zone and the clarification zone. This is because the solubility of the glass liquid gradually decreases from the clarification zone to the pre-melting zone of the furnace, and the influence of the electrical resistivity of the glass liquid on the glass cold material increases more. If the electrode spacing of the pre-melting zone is too wide, the risk of fluctuation of the electrical resistivity of the glass liquid will increase, which may cause fluctuations in the electrode melting process of the pre-melting zone. The present invention reduces the electrode spacing of the pre-melting zone through the non-uniform spacing design of the furnace, improves the operating stability of the electrode energization process of the furnace, and can reduce the risk of fluctuations in the electrode energization process and power failure due to fluctuations in the electrical resistivity of the glass liquid.

[0039] The present invention adopts a double electrode and a non-uniform spacing design in the front zone of the furnace, and further combines the dual electrical hybrid heating method in the pre-melting zone of the furnace to achieve high-efficiency melting of the glass liquid under a large flow rate and the stability of the furnace operation.

[0040] Based on the above structure, the present invention discloses an operating method of a pre-zone double-electrode non-uniform-spacing furnace for performing melting with high efficiency under a large flow rate. Referring to FIG. 4, the following steps are included.

[0041] Step S1: Glass powder is input from the supply port 4 into the preliminary melting zone 6, and the glass powder is preliminarily melted using the electrode 2 to form a glass liquid.

[0042] Step S2: The glass liquid moves from the preliminary melting zone 6 to the homogenization zone 7, enters the clarification zone 8 after being sufficiently mixed and homogenized, undergoes preliminary clarification, and flows out from the discharge port 5 when the preliminary clarification is completed.

[0043] As shown in FIG. 4, in other embodiments of the present invention, adaptive modifications according to the situation can be made. Glass powder is input from the supply port 4 into the preliminary melting zone 6, and the glass powder input from different supply ports is separated to avoid the mutual interference of the melting processes of the material piles at different supply ports in the preliminary melting process. The glass powder is preliminarily melted using the electrode 2 to form a glass liquid. The glass liquid enters the homogenization zone 7 from the preliminary melting zone 6, proceeds to the clarification zone 8 after being sufficiently mixed and homogenized, undergoes preliminary clarification, and flows out from the discharge port 5 when the preliminary clarification is completed. By reducing the electrode spacing in the preliminary melting zone and the non-uniform-spacing design of the furnace, the operating stability of the electrode energization process of the furnace can be improved, and the risks of fluctuations in the electrode energization process and power failure due to fluctuations in the electrical resistivity of the glass liquid can be reduced. The method of the present invention can ensure the high-efficiency melting of the glass liquid under a large flow rate and the stability of the furnace operation, and reduce the occurrence of the "power cut-off" phenomenon.

[0044] (Example 5) This example discloses an operating method of a pre-zone double-electrode non-uniform-spacing furnace for performing melting with high efficiency under a large flow rate, and includes the following steps.

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

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

[0047] Step 3: The glass liquid that has been sufficiently mixed and homogenized enters the clarification zone 8, where preliminary clarification is performed. When the preliminary clarification is completed, it flows out from the discharge port 5.

[0048] The above is only a preferred embodiment of the present invention and is not intended to limit the technical solution of the present invention. Those skilled in the art can also make simple modifications and substitutions to the technical solution of the present invention without departing from the gist and principle of the present invention. These modifications and substitutions are included within the scope of protection covered by the claims of the present invention.
