Abstract
Description
Technical Field
[0001] The utility model relates to the field of auxiliary equipment for electronic glass furnaces, and particularly relates to an adjusting device for electrodes of an electronic glass furnace. Background Art
[0002] Electric heating of electronic glass furnaces is currently the main method in this industry. Among them, tin oxide electrodes are the most widely used materials because tin oxide not only has good electrical conductivity, but its components also have the function of glass clarification. However, the tin oxide electrodes will be continuously consumed during operation, and it is necessary to regularly push the electrode ends into the furnace.
[0003] Currently, when the electrodes are initially installed, the front parts of the electrodes are placed on the bottom of the furnace pool, and the exposed parts of the electrodes are externally supported by special supporting devices. When the furnace starts to heat up, the refractory material structure at the bottom of the pool under the front part of the electrode expands due to heat, generating displacements in the upward and front-back directions of the furnace, and at the same time driving the front part of the electrode to have displacements in the upward and front-back directions (the left-right direction of the electrode). Among them, the upward expansion destroys the initial horizontal state of the electrode, and the front-back expansion drives the front part of the electrode to move forward or backward. However, the rear part of the electrode is outside the furnace and is fixed, resulting in the front part of the electrode being offset left and right, and the gaps on the left and right with the pool wall being inconsistent. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an adjusting device for electrodes of an electronic glass furnace to solve the problem of left-right offset of the front part of the electrode when the furnace heats up.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] In a first aspect, an adjusting device for electrodes of an electronic glass furnace includes: an insulating backing plate, a sliding plate, a pulley, a second bottom plate, and a bottom lifting assembly;
[0007] The pulley is arranged on the side surface of the sliding plate. The insulating backing plate is installed on the top surface of the sliding plate. The second bottom plate is installed on the bottom surface of the sliding plate. Upward protruding shielding structures are arranged at both ends of the second bottom plate. During use, the shielding structures shield in the movement direction of the sliding plate to prevent the sliding plate from falling. The bottom lifting assembly is installed at the bottom of the second bottom plate. During use, the bottom lifting assembly adjusts the height of the second bottom plate, thereby driving the lifting of the heights of the sliding plate and the insulating backing plate.
[0008] In some embodiments, the cross-section of the pulley is trumpet-shaped, and the waist edge of the pulley is arc-shaped. During use, the waist edge of the pulley contacts both ends of the second bottom plate and rolls.
[0009] In some embodiments, the bottom lifting assembly includes: a first bottom plate, a wedge block, and a slider. The wedge block is fixedly installed at the bottom of the second bottom plate, and the slider is installed on the first bottom plate. The wedge block and the slider cooperate to adjust the height of the second bottom plate.
[0010] In some embodiments, the wedge block includes a first wedge block and a second wedge block. The slider is a trapezoidal slider. The first wedge block is fixed on the first bottom plate, the second wedge block is fixed at the bottom of the second bottom plate, and the trapezoidal slider is arranged between the first wedge block and the second wedge block. The inclined surface of the trapezoidal slider is in fitting contact with the surfaces of the first wedge block and the second wedge block. During use, the moving direction of the trapezoidal slider is perpendicular to the moving direction of the pulley. At this time, the trapezoidal slider moves between the first wedge block and the second wedge block to adjust the height of the second bottom plate.
[0011] In some embodiments, the first wedge block and the second wedge block are respectively threadedly connected to the first bottom plate and the second bottom plate.
[0012] In some embodiments, the first bottom plate is an L-shaped plate.
[0013] In some embodiments, an adjustment bolt is arranged on the side surface of the first bottom plate, and the adjustment bolt is connected to the trapezoidal slider.
[0014] In some embodiments, the pulley is screw-connected to the side surface of the sliding plate.
[0015] In some embodiments, the pulley pin shaft is connected to the side surface of the sliding plate.
[0016] In some embodiments, the pulley is made of stainless steel, and the insulating backing plate is made of alumina.
[0017] Compared with the prior art, the present utility model has the following beneficial effects:
[0018] The present utility model provides an adjustment device for an electrode of an electronic glass furnace. The pulley is arranged on the side surface of the sliding plate, the insulating backing plate is installed on the top surface of the sliding plate, the second bottom plate is installed on the bottom surface of the sliding plate, upwardly protruding shielding structures are arranged at both ends of the two sides of the second bottom plate, the bottom lifting assembly is installed at the bottom of the second bottom plate, the electrode is placed on the insulating backing plate, and through the adjustment of the bottom lifting assembly, the initial horizontal state of the electrode can be restored. At the same time, through the cooperation of the pulley and the sliding plate moving on the second bottom plate, the insulating backing plate is driven to move to adjust the electrode position, so that when the tail of the electrode moves back and forth with the furnace, it moves synchronously in the left and right directions, eliminating the left and right offset problems of the electrode.
[0019] Furthermore, the present utility model arranges an adjustment bolt on the side surface of the first bottom plate, which can make the trapezoidal slider more stable during the moving process and fix it after the moving of the trapezoidal slider is completed, eliminating the problem of the front being high and the back being low caused by the expansion of the refractory material at the bottom of the pool.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more such features.

[0031] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0032] Embodiment 1
[0033] As Figure 1 shown, the front part of the electrode 11 is placed on the bottom brick 13 of the tank, the rear part of the electrode 11 is placed on the bottom support block 12, and the tank wall brick 14 of the kiln furnace and the electrode 11 are both placed on the bottom brick 13 of the tank. During the heating-up stage, the front part of the electrode 11 is subjected to the upward expansion force of the bottom brick 13 of the tank and is lifted by about 5 mm. Since the support block 12 does not expand outside the kiln furnace, the situation of the front part of the electrode 11 being high and the rear part being low occurs, which affects the subsequent electrode propulsion operation. At the same time, the bottom of the tank will also expand back and forth, driving the electrode 11 and the tank wall brick 14 to move. Since the rear support block 12 of the electrode does not expand, the gaps 15 on both sides of the electrode will be of different sizes, and the electrode will be offset, which will still affect the electrode propulsion operation, as Figure 2 shown.
[0034] Therefore, this embodiment provides an adjustment device for the electrode of an electronic glass kiln furnace, as Figure 3 shown, including: a left-right adjustment component and a bottom lifting component;
[0035] The left-right adjustment component includes: an insulating backing plate 31, a sliding plate 32, a pulley 33, and a second bottom plate 22;
[0036] As Figure 4As shown in the figure, the bottom lifting assembly includes: a first bottom plate 21, a first wedge block 23, and a second wedge block 24. The slider is a trapezoidal slider 25. The first wedge block 23 is fixed on the first bottom plate 21, and the second wedge block 24 is fixed at the bottom of the second bottom plate 22, forming a triangular space. The trapezoidal slider 25 is arranged between the first wedge block 23 and the second wedge block 24. The inclined surface of the trapezoidal slider 25 is in fitting contact with the surfaces of the first wedge block 23 and the second wedge block 24. The first wedge block 23 and the second wedge block 24 are respectively threadedly connected to the first bottom plate 21 and the second bottom plate 22. During use, the moving direction of the trapezoidal slider 25 is perpendicular to the moving direction of the pulley 33. At this time, the trapezoidal slider 25 moves between the first wedge block 23 and the second wedge block 24 to adjust the height of the second bottom plate 22. During the forward sliding process of the trapezoidal slider 25, the second wedge block 24 is lifted, causing the second bottom plate 22 and the components above it to be lifted, ultimately lifting the electrode tail and eliminating the problem of the front being high and the back being low caused by expansion.
[0037] The first bottom plate 21 is an L-shaped plate. An adjustment bolt 26 is arranged on the side surface of the first bottom plate 21. The adjustment bolt 26 is connected to the trapezoidal slider 25. The pulley 33 is screw-connected to the side surface of the sliding plate 32. The trapezoidal slider 25 is connected to the adjustment screw through a threaded hole and can slide along the inclined surface of the first wedge block 23 under the action of the adjustment bolt 26.
[0038] The pulley 33 is screw-connected to the side surface of the sliding plate 32. The insulating backing plate 31 is installed on the top surface of the sliding plate 32. The second bottom plate 22 is installed on the bottom surface of the sliding plate 32. Upward protruding shielding structures 222 are arranged at both ends of the second bottom plate 22. As Figure 5 shown, the top height of the shielding structure 222 is higher than the bottom surface of the sliding plate 32. During use, the shielding structure 222 shields in the moving direction of the sliding plate 32 to prevent the sliding plate 32 from falling. The bottom lifting assembly is installed at the bottom of the second bottom plate 22. During use, the bottom lifting assembly adjusts the height of the second bottom plate 22, thereby driving the height increase of the sliding plate 32 and the insulating backing plate 31. The cross-section of the pulley 33 is trumpet-shaped, and the waist side of the pulley 33 is arc-shaped. During use, as Figure 6 shown, the arc-shaped waist side 331 of the pulley 33 contacts the edge 221 at the upper part of both ends of the second bottom plate 22 and rolls.
[0039] When the front part of the electrode 11 moves left or right along with the expansion of the kiln, its electrode 11 tail is placed on the insulating backing plate 31 and also moves left and right accordingly, forming an automatic adjustment of the position, avoiding the problem of electrode offset caused by the expansion of the kiln.
[0040] Preferably, the pulley 33 is made of stainless steel, and the insulating backing plate 31 is a refractory material and is made of alumina material.

The second bottom plate 22 is installed on the bottom surface of the sliding plate 32. Shielding structures 222 protruding upward are arranged at both end portions on the two sides of the second bottom plate 22. During use, the shielding structures 222 shield in the moving direction of the sliding plate 32 to prevent the sliding plate 32 from falling. The bottom lifting assembly is installed at the bottom of the second bottom plate 22. During use, the bottom lifting assembly adjusts the height of the second bottom plate 22, thereby driving the lifting of the heights of the sliding plate 32 and the insulating backing plate 31.
[0044] The bottom lifting assembly includes: a first bottom plate 21, a wedge block, and a slider. The wedge block is fixedly installed at the bottom of the second bottom plate 22.
