Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass manufacturing, in particular to an electrode lifting device for a substrate glass kiln. Background Art
[0002] In the substrate glass furnace, the electric boosting adopts the current control mode in operation. The power of converting electrical energy into heat energy in the glass liquid is P=I2R. When the temperature of the glass liquid decreases, the resistance R increases. If the electrode current I remains unchanged, then P increases with the increase of R, thereby increasing the heating of the glass liquid; conversely, when the temperature of the glass liquid increases, the electric boosting can reduce the heating of the glass liquid. In this way, the heating of the glass liquid by the electric boosting and the change of the temperature of the glass liquid itself reach a dynamic balance, so that the temperature of the glass liquid remains dynamically stable.
[0003] Electric melting uses high-temperature tin oxide electrodes, which are paired in two groups and arranged symmetrically and evenly on the pool walls on both sides of the kiln. The contact surface with the glass liquid and the inner side of the pool wall are kept on the same plane. During production, as the electrode erosion loss increases, it can be pushed in gradually. The pushing process is called electrode pushing operation.
[0004] When pushing the electrode, before pushing the electrode in, it is necessary to use professional insulating tools to lift the lifting device at the bottom of the electrode so that it can safely bear the weight of the electrode and completely separate the bottom of the electrode from the pool wall brick at the bottom of the electrode brick. In the prior art, one is a lifting device using insulating balls, which has the disadvantage that it cannot ensure that the gaps between the left and right sides of the electrode group and the electrode holes in the pool wall are uniform. Another type of lifting device uses insulating ceramic rods, but the insulating ceramic rods interfere with each other during operation of the lifting device, which can easily cause the insulating ceramic rods to get stuck and unable to rotate during operation. In summary, how to design a lifting device that ensures that the gaps between the motor group and the two sides of the pool wall are uniform and the insulating ceramic rods do not interfere with each other during the electrode advancement process has become a technical problem that urgently needs to be solved in this industry.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] As attached Figure 2 As shown, the pool wall is assembled by dry-laying rectangular fused high-zirconium bricks of different sizes, and rectangular electrode holes are reserved on the pool wall according to the outer dimensions and position distribution of the electrode 3. The electrode 3 is assembled by neatly arranging electrode bricks of the same specifications and materials, and is installed in the electrode hole of the pool wall. The contact surface of the electrode 3 and the glass liquid is flush with the inner side of the pool wall. The bottom surface of the electrode 3 is supported by a pool wall brick of a specific size and an electrode lifting device 4. A 2mm gap is left between the side and top surfaces of the electrode 3 and the inner wall of the reserved electrode hole on the pool wall so that the electrode 3 can slide freely during the electrode pushing operation. The electrode gap is blown by the duckbill air nozzle to prevent the glass liquid from leaking. The side opposite to the contact surface of the electrode 3 and the glass liquid is fitted with the water-cooled plate, and the connection method is a combination of bolts and pins. In recent years, in order to extend the service life of the electrode, the length of the electrode brick has been lengthened in design, so that the center of gravity of the electrode is moved backward, and an electrode pad brick 5 is added to support the electrode lifting device 4 that moves backward. The bottom of the electrode pad brick 5 is supported by a steel structure. The pool bottom 2 is dry-laid and assembled by pool bottom bricks of different specifications and materials and fillers to provide support for the upper structure and glass liquid. The technical solution of the utility model aims to improve the structure of the jacking device 4 so that the electrode 3 can be pushed smoothly and efficiently during the overall production operation.
[0023] As attached Figures 2-3As shown, the electrode lifting device of the substrate glass furnace of the utility model includes a rectangular frame 6, a rectangular countersunk hole 60 arranged on the rectangular frame 6 and opening downward; a wedge block 8 arranged at the lower end of the rectangular frame 6; an adjusting screw 9 for adjusting the wedge block 8 at a close distance; an insulating ceramic rod 10 arranged in the rectangular countersunk hole 60; the wedge block 8 enables the rectangular frame 6 to produce different working heights by feeding; when subjected to external force, the insulating ceramic rod 10 produces a rotational motion with its own axis as the axis in the rectangular countersunk hole 60. The rectangular frame 6 serves as the main force-bearing structure, and the insulating ceramic rod 10 arranged at the upper end thereof directly contacts the bottom plane of the electrode 3 when lifting, and multiple insulating ceramic rods 10 form a force-bearing surface to implement uniform advancement of the electrode 3.
[0024] As a comparison, Figure 4 The schematic diagram of the structure of the existing electrode lifting device is shown in FIG. The base 7 is the support of the lifting device, which is installed on the pool bottom 2 and the electrode pad brick 5. An alumina insulating plate is installed under the base 7 to ensure that the lifting device is insulated from the pool bottom 2. The wedge 8 is installed on the base 7. By adjusting the position of the adjusting screw 9, free sliding can be achieved forward and backward, which is used to accurately adjust the height of the rectangular frame 6. The angle of the wedge at the bottom of the rectangular frame 6 matches the angle of the wedge 8 to keep it horizontal. The insulating balls 11 are neatly and evenly arranged on the rectangular frame 6 and are limited by the sleeve. The bottom of the sleeve is welded to the rectangular frame 6. The inner diameter of the sleeve is slightly larger than the diameter of the insulating ball 11 to ensure that the insulating ball 11 placed therein can rotate freely. The insulating ball 11 is in direct contact (tangent) with the bottom surface of the electrode 3 to support the weight of the electrode group. The insulating ball 11 is made of 95 porcelain. The existing electrode lifting device exposes a problem in practice, that is, when installing the electrode brick, the electrode gap of 2 mm must be maintained between the left and right sides of the electrode group 3 and the electrode hole of the pool wall, and the left and right sides must be uniform. However, even if the installation process is strictly carried out according to the technical indicators, most of the gaps between the electrodes on the left and right sides will change after installation. One side will become smaller and the other side will become larger. The smaller side will even be close to the pool wall, which will hinder the subsequent electrode pushing operation. The larger side will increase the risk of glass liquid seeping out at high temperatures. Since the insulating ball is universally rotatable, the left and right sides of the electrode can be freely offset, so the insulating ball support structure will cause the above disadvantages.
[0025] Figure 5Another structural schematic diagram of the existing electrode lifting device. As shown in the figure, the difference between this structure and the previous structure is that the insulating ceramic rods 10 are used instead of the insulating ceramic balls 11. The insulating ceramic rods 10 are neatly arranged and embedded in rectangular countersunk holes 60 on the rectangular frame 6 in groups. The rectangular countersunk holes 60 limit the position of each group of ceramic rods. The advantage of this structure is that it limits the left and right deviation of the electrode 3, ensuring that the electrode gaps on the left and right sides are uniform and consistent, meeting the installation specifications and use requirements. However, there is a problem with this structure in actual use, that is, there is a situation where adjacent insulating ceramic rods 10 are stuck and do not rotate, thereby hindering the advancement of the electrode.
[0026] In the embodiment of the technical solution of the present application, a wedge-shaped fixed block coupled with the slope surface of the wedge block 8 is provided at the lower part of the rectangular frame 6. During the feeding process of the wedge block 8, the combined action with the wedge-shaped fixed block causes the rectangular frame 6 to be in a horizontally lifted state. The wedge-shaped fixed block is fixedly arranged below the rectangular frame 6. When it is coupled with the wedge block 8, the feeding of the wedge block 8 causes the wedge-shaped fixed block to move relative to the wedge block 8, lifts in the vertical direction, and thus drives the rectangular frame 6 to move synchronously.
[0027] In the embodiment of the technical solution of the present application, the insulating ceramic rod 10 is made of 95 porcelain. The insulating ceramic rod is made of insulating material so that it has the ability to conduct upward force without affecting the electrical performance of the electrode 3.
[0028] In the technical solution embodiment of the present application, the plurality of rectangular countersunk holes 60 are evenly distributed on the rectangular frame 6, and the insulating ceramic rod 10 is in line contact when in contact with the lifted component. During the lifting process of the motor 3, the lifting mechanism 4 pushes the electrode 3 evenly and smoothly, which is a key technical requirement. A plurality of rectangular countersunk holes 60 are used, which are evenly distributed on the rectangular frame 6, so as to ensure that the corresponding insulating ceramic rod 10 forms a force surface for the electrode 3. At the same time, the insulating ceramic rod 10 is in line contact with the ground of the electrode 3. When the insulating ceramic rod 10 is subjected to the friction force of the bottom surface of the electrode 3, the movement of the insulating ceramic rod 10 in its own axial direction can be restricted, and the advancement of the electrode 3 is further stabilized and smooth without deviation.
[0029] In the embodiment of the technical solution of the present application, the insulating ceramic rods 10 are arranged in groups. The insulating ceramic rods 10 match the number of the corresponding rectangular countersunk holes 60, and can be flexibly selected according to the bottom area of the electrode 3 to achieve a better lifting effect.
[0030] When in use, the wedge block 8 is fed by adjusting the screw rod 9, and the rectangular frame 6 is vertically lifted by the action of the wedge-shaped fixing block coupled therewith. The insulating ceramic rod 10 contacts the bottom plane of the electrode 3 to lift it.
[0031] The advantage of the utility model is that the electrode lifting device uses insulating ceramic rods to replace the previous insulating ball setting, ensuring that the gap between the motor group and the two sides of the pool wall is uniform during the electrode advancement process. Independent insulating ceramic rods are used to install the countersunk holes, so that during the lifting operation, the insulating ceramic rods are independent of each other, avoiding the phenomenon of jamming and stopping, and improving production efficiency.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
