Description

Technical Field

[0001] The present invention belongs to the field of auxiliary devices for electronic glass melting furnaces, and specifically relates to an automatic propulsion device and propulsion method for tin oxide electrodes in electronic glass melting furnaces.

Background Art

[0002] Electric heating is currently the main method used in the industry for electronic glass melting furnaces, which mainly employs molybdenum electrodes and tin oxide electrodes. Among them, tin oxide electrode is the most widely used material. Tin oxide not only has good conductive properties, but also its components have a fining effect on glass, so it is most widely applied. However, since tin oxide electrodes are continuously consumed during operation, it is necessary to periodically push the end face of the electrode into the melting furnace to maintain a stable voltage. Nevertheless, as the capacity of melting furnaces continues to increase, the specification and size of electrodes continue to increase, and the pushing resistance of electrodes also continues to increase, with the maximum resistance reaching approximately 3000 kg. The conventional screw support method requires manual operation, resulting in high work intensity, and the rigidity of the screw continues to decrease during the extension process, which is prone to causing problems such as screw bending and jamming.

[0003] The technical problem of the prior art is that screw bending and jamming are prone to occur when propelling electrodes.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] As shown in Figure 1 and Figure 2, the present embodiment provides an automatic propulsion device for tin oxide electrodes in an electronic glass furnace, comprising a motor drive unit, a motor guide unit and a motor control unit. The motor drive unit comprises a worm gear 21, a coupling 24, a push rod 25 and a geared motor 23, wherein the worm gear is connected to the geared motor 23 via the coupling 24, and the push rod 25 is mounted at an end of the worm gear 21. The geared motor 23 functions to drive the worm gear 21 to operate, achieving efficient torque input; the worm gear 21 achieves propulsion of the push rod to move forward through its torque amplification function, reaching the propulsive force required for the propulsion operation. The motor guide unit comprises a carriage 11 and a guide rail 12, the motor drive unit is mounted on the carriage 11, the guide rail 12 is mounted at the bottom of the carriage 11, and in use, the carriage 11 moves on the guide rail 12 to control the propulsion direction of the motor drive unit. The motor control unit is connected to the geared motor 23 and is used for controlling the geared motor 23 to propel the push rod 25.

[0026] Specifically, the worm gears 21 are attached to both the left and right sides of the front end of the trolley 11, and the push rod 25 is attached to the front of the worm gears 21, thereby forming two propulsion points. Here, the trolley 11 has a front end which is the mounting and fixing part for the motor drive unit, and a rear end which is the moving part. The motor drive unit further includes a handwheel 22 mounted on the upper end of the worm gear 21.

[0027] The motor drive unit further includes a position regulating device 13, which includes a vertical position regulating device 13-1 and a longitudinal position regulating device 13-2 attached to the connection point between the bogie 11 and the guide rail 12, wherein the vertical position regulating device 13-1 prevents the bogie 11 from being lifted while under force, and the longitudinal position regulating device 13-2 prevents the bogie 11 from moving backward due to the reaction force of the thrust force of the electrodes.

[0028] The position-regulating butt joint structure of the vertical position regulating device 13-1 is a U-shaped notch.

[0029] The butt joint structure for position regulating the front-rear position regulating device 13-2 is a strip-shaped through hole.

[0030] An insulated ceramic head is attached to the end of the push rod 25.

[0031] As shown in Figure 3, this is an automatic propulsion method for tin oxide electrodes in an electron glass furnace, After pushing the trolley 11 to a predetermined position using the guide rail 12, it is fixed in place to restrict its position. Then, the extension amount of the worm gear is finely adjusted using the handwheel 22, and the end of the push rod 25 is brought into contact with the electrode reinforcing pressure plate 31. Subsequently, when the synchronous start button is pressed, the motor control unit completes the propulsion of the tin oxide electrode by controlling the geared motor 23 to propel the two push rods 25 synchronously, and if the electrode is deflected to one side (for example, to the left), the tip of the right push rod 25 is adjusted to contact the electrode reinforcing pressure plate 31, and when the right independent start button is pressed, the geared motor 23 drives the push rod 25 to achieve calibration of the electrode deflected to the left.

[0032] Here, it is necessary to set the propulsion amount stages in advance, and according to the different propulsion amount stages, the motor control unit controls the geared motor 23 to propel the push rod 25, and when the propulsion amount corresponding to the propulsion amount stage is reached, the propulsion of the push rod 25 is stopped.

[0033] Finally, when the position control device 13 is released, the entire trolley 11 moves back along the guide rail 12 on the bottom, and the work is completed.

[0034] As is common technical knowledge, the present invention can also be realized by other embodiments that do not depart from its essential idea or necessary features. Therefore, the embodiments disclosed above are in all respects merely illustrative and not unique. Any modifications within the scope of the present invention, or equivalents thereof, are included in the present invention. [Explanation of Symbols]
