LIFT FOR ASSEMBLY ELECTRODE OF ELECTRIC BOOSTER USE IN A GLASS MELTING FURNACE}
[15] The present invention relates to a glass melting furnace for heating a batch of injected glass raw material to melt in a liquid phase, and more particularly, in a hot spot area between a melting part and a clarification part of a melting furnace, The present invention relates to an electric booster electrode installation lift that enables to quickly and easily install an electrode of an electric booster (electric booster) that induces electric resistance heat generation in glass.
[16] For example, bulbs for cathode ray tubes used in the manufacture of color televisions, computer monitors, etc. are basically three components: a panel through which images are projected, and a rear panel of the panel. It consists of a fallopian-shaped funnel and a tubular neck fused to the rear end of the funnel. These panels, funnels and necks are made of high-quality glass free from defects due to the nature of the cathode ray tube, which must maintain high vacuum. In particular, the panels and funnels press-mold molten glass lumps called glass gobs to the desired size and shape. Manufactured by
[17] Accordingly, the glass melting furnace for manufacturing the glass material for the cathode ray tube melter (melter) for melting the injected glass raw material, and the clarification unit for removing and homogenizing the bubbles in the glass material introduced from the melter through the throat (throat) ( a refiner) and a forehearth for supplying the clarified glass to the forming part are continuously connected.
[18] On the other hand, the productivity of glass melting is determined by the quality level and production of molten glass, and the appropriate output can be expressed by the ability to dissolve per unit area. If the amount of production per unit area is exceeded by experience, the desired quality level cannot be created. Therefore, the area of the melting furnace needs to be increased to increase the output. However, to increase the melting area, there are many problems due to the high investment cost and lack of operation experience. There is no economy. In addition, the heat supply by the general combustion is not only low efficiency requires a large amount of fuel, but also has a problem that the life of the furnace is shortened due to the erosion of the upper structure of the furnace. Accordingly, it is common to apply an electric booster system with good thermal efficiency to increase production and improve quality.
[19] The electric booster is usually installed at the bottom of the hot spot area where high temperature is required for the separation of the melting part and the clarification part, thereby preventing the unmelted raw material of the melting part from entering the clarification part, and at the same time, greatly affecting the product quality. The impact promotes the melting of the raw material in the melt by enhancing the convection current. In addition, when an increase in the amount of melt production or supply of additional heat is required, a high voltage current is applied to the molten glass to induce heat generation of electrical resistance of the glass, thereby replenishing the required heat.
[20] To this end, the electric booster electrode is installed to penetrate the bottom of the melting furnace vertically to penetrate the molten glass. Conventionally, the electrode is simply installed by hand or by using a hydraulic jack. However, it is extremely difficult and dangerous to manually install a large electrode at the bottom of a glass melting furnace having a large ground clearance with a very large structure, and also to center the assembly hole or the cooling holder of the electrode block into which the electrode and the electrode are inserted. Many difficulties followed. In particular, since the electrode rod should be rotated during the work for sealing the glass on the electrode, the installation work is difficult and the work time is long.
[21] The present invention has been made to solve the various problems of the prior art as described above, an object of the present invention is to provide an electric booster electrode installation lift that can be easily and quickly installed in the bottom of the electric booster electrode to the glass melting furnace have.
[22] Another object of the present invention is to provide an electric booster electrode installation lift which can easily perform centering between an assembly hole of a electrode block and an electrode block into which an electrode is inserted or a cooling holder.
[23] Still another object of the present invention is to provide an electric booster electrode installation lift that can easily rotate the electrode rod in a stable support state during the glass sealing operation of the electrode.
[24] In order to achieve the above objects, the electric booster electrode mounting lift according to the present invention includes a base frame; A main table arranged horizontally above the base frame; Elevating means for elevating the main table with respect to a base frame; An X-Y table mounted on the main table and movable in a direction perpendicular to each other; It is provided on this X-Y table, It is characterized by including the bearing holder which rotatably supports an electrode.
[25] Accordingly, the present invention can easily align the center of the electric booster electrode with the electrode block assembly hole or the cooling holder, as well as the glass sealing operation for the electrode can be performed very easily. Booster electrode installation can be done easily and quickly.

That is, corresponding ends of adjacent link pairs 31 to 33 are stretched by pivotal coupling. Meanwhile, one unit link 31a of the lowermost link pair 31 is rotatably assembled and fixed to the base frame 10, and the other unit link 31b is guide roller 31c as shown in FIG. 3. ) Is movably coupled to the guide groove 14 formed horizontally in the base frame 10. The top link pair 33 also has one unit link 33a rotatably assembled and fixed to the main table 20, and the other unit link 33b includes a guide roller 33c to hold the main table 20. It is movably coupled to the guide groove 21 formed horizontally in the). The pantograph 30 is provided in pairs arranged side by side at a predetermined interval, and each pair of opposing link pairs 31 to 33 are assembled in an X shape by one hinge pin 34 for stable operation. .
[30] On the other hand, one unit link 31b of the lowermost link pair 31 is pivotally supported by the rear end of the cylinder 40 that expands and contracts the pantograph 30, and one of the link pairs 32 connected to the unit link 31b is pivotally supported. The front end of the piston rod 41 is pivotally supported on the unit link.
[31] The XY table 50 is composed of an X table 51 slidably assembled on the main table 20 and a Y table 54 slidably assembled in a direction perpendicular to the X table 51. Is done. Although not shown in detail in the drawings, each of the tables 51 and 54 is assembled in a dovetail manner, and is relatively slid by the transfer screws 52 and 55 such as ball screws. In addition, each of the transfer screws 52 and 55 is provided with handles 53 and 56 for manipulating them.
[32] As shown in detail in FIG. 4, the bearing holder 60 is mounted on the Y table 54 via the bearing 64 to insert the lower end of the electrode E, and the Y table ( And a housing 62 installed on the holder socket 61 and bearing 64. The upper surface of the housing 62 is formed with a hole 63 so that the lower end of the electrode rod E can be inserted into the holder socket 61. The guide 70 fixes the position so that the electrode rod E supported by the bearing holder 60 does not fall, and the lift may be operated by the control box 80 or the manual handle 81.
[33] The operation of the electric booster electrode rod mounting lift according to the present invention thus constructed will now be described.
[34] First, the lift is properly positioned at the bottom of the bottom of the glass melting furnace in which the electrode rod E is to be installed, and the lift is fixed by the legs 13 of the base frame 10 so as not to move to the corresponding position. Next, in the state in which the main table 20 is lowered, as shown by the virtual line in FIG. 1, the electrode rod E to be installed on the bearing holder 60 is mounted and the electrode rod E is fixed by the guide 70. .
[35] Next, the up button of the control box 80 is pressed or the manual knob 81 is pumped. Then, as shown by the solid line in FIG. 1, the cylinder 40 expands and the piston rod 41 advances, thus corresponding one unit link 31b of the top and bottom link pairs 31 and 33. The pantograph 30 extends upwardly to raise the main table 20 by moving the 33b in a narrowing direction along the guide grooves 14 and 21 of the base frame 10 and the main table 20. Let's do it.
[36] On the other hand, when the main table 20 is raised to an appropriate position, the operation of the cylinder 40 is stopped and the XY table 50 is operated to assemble the electrode block EB provided in the electrode rod E and the bottom B. Center). Such centering is fine and precisely adjusted by the X-Y table 50 in a state in which the electrode E is stably supported perpendicularly to the bearing holder 60, so that the centering operation can be performed very simply. When the centering between the electrode rod E and the electrode block assembly hole H is completed, the restraint of the electrode rod E by the guide 70 is released, and the cylinder 40 is driven again to raise the main table 20 further. 5, the electrode rod E is inserted into the assembly hole H of the electrode block EB.
[37] When the molten glass is filled to some extent in the melting furnace after the electrode rod E is inserted in this manner, the electrode rod E is lowered while rotating to perform a glass sealing operation on the electrode rod E. At this time, since the holder socket 61 on which the electrode rod E is supported is supported by the Y table 54 and the bearing 64, the electrode rod E rotates very smoothly, and thus the sealing operation can be easily performed. Will be.
[38] Finally, when the glass sealing operation to the electrode (E) is completed, press the down button of the control box (80). Then, the piston rod 41 of the cylinder 40 is retracted, and thus the main table 20 is lowered to the initial position by moving and contracting in the direction in which the link pairs 31 to 33 of the pantograph 30 are opened. . Therefore, the electric booster electrode E can be installed very simply and quickly with respect to the bottom B of the glass melting furnace.
