Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a silicon core furnace electrode alignment detection tool. Background Art

[0002] The copper electrode for auxiliary heating at the bottom of the silicon core furnace is a lifting structure. During operation, the copper electrode and the electrode mounting hole at the bottom of the furnace (the inner diameter of the latter is larger than the outer diameter of the former) will be misaligned, causing the thermal field (graphite main electrode) assembly to be affected. Therefore, it is necessary to stop the machine and perform centering measurement and correction on the copper electrode.

[0003] At present, the centering measurement and correction of copper electrodes are completed by one person observing and measuring inside the furnace and directing another person to perform the centering operation at the bottom outside the furnace. Among them, the personnel inside the furnace use a steel ruler to repeatedly measure the annular gap between the copper electrode and the electrode installation hole. The steel ruler is prone to measurement deviation in the arc surface between the outer wall of the copper electrode and the inner wall of the hole. The feedback dimensional accuracy is low, and it is inconvenient to observe, resulting in slow centering operation and long time. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A silicon core furnace electrode alignment detection tool, comprising:

[0007] A cylindrical tube, used to cover the electrodes of the silicon core furnace;

[0008] An annular member is sleeved on the outer edge of the bottom of the cylindrical barrel, and has an annular plug-in portion whose outer diameter matches the inner diameter of the furnace bottom electrode mounting hole; and

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0042] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1 to Figure 3 As shown, the utility model provides a silicon core furnace electrode alignment detection tool, comprising:

[0044] The cylindrical barrel 10 is used to cover the electrode of the silicon core furnace (not shown in the figure);

[0045] The annular member 20 is sleeved on the outer edge of the bottom of the cylindrical tube 10, and has an annular plug-in portion 21 whose outer diameter matches the inner diameter of the furnace bottom electrode mounting hole; and

[0046] The detection plate 30 covers the top of the cylindrical tube 10;

[0047] The detection plate 30 is made of a transparent material and has four scale lines 31 disposed in the middle thereof. The four scale lines 31 are orthogonal (ie, spaced 90° apart from each other) to the axis of the cylindrical tube 10 .

[0048] When in use, the annular plug-in portion 21 of the annular member 20 is inserted into the electrode mounting hole at the bottom of the furnace, so that the cylindrical tube 10 covers the electrode of the silicon core furnace. Since the outer diameter of the annular plug-in portion 21 matches the inner diameter of the electrode mounting hole at the bottom of the furnace, the cylindrical tube 10 is exactly coaxial with the electrode mounting hole (the orthogonal point of the four scale lines 31 is concentric with the electrode mounting hole). Then the personnel in the furnace observe the correspondence between the four scale lines 31 around the electrode through the transparent detection plate 30. If they are not on the same scale value, the personnel at the bottom outside the furnace are instructed to adjust the position of the electrode until the four scale values ​​correspond to the same scale value on all sides, that is, the electrode centering operation is completed. That is to say, by the fitting of the annular plug-in portion 21 with the inner wall of the electrode mounting hole at the furnace bottom, the cylindrical tube 10 is ensured to be coaxial with the electrode mounting hole, so that the orthogonal points of the four scale lines 31 are concentric with the electrode mounting hole, and the correspondence between the four scale lines 31 around the electrode is observed through the transparent detection plate 30, so that the electrode centering operation can be quickly completed; compared with the existing steel ruler measurement, the repeated manual measurement steps are eliminated, the dimensional feedback of the four scale lines 31 is highly accurate, the transparent detection plate 30 is easy to observe, the centering operation time is short, and the efficiency is high.

[0049] In order to facilitate the observation of the correspondence between the electrode periphery and the four scale lines 31, a center circle 32 with the orthogonal point of the four scale lines 31 as the center is provided on the detection plate 30, and the diameter of the center circle 32 matches the diameter of the electrode. By observing the horizontal centering deviation between the center circle 32 and the electrode, the corresponding scales between the electrode periphery and the four scale lines 31 can be quickly found, and the direction and distance of the electrode misalignment can be fed back to the personnel at the bottom outside the furnace, which is conducive to further improving the efficiency of the electrode centering operation.

[0050] See also Figure 3As shown, the scale value corresponding to the orthogonal point of the four scale lines 31 is 0, and the maximum scale value of each scale line 31 is 4 cm. The maximum scale value of 4 cm can be fully mapped to the range of the furnace bottom electrode installation hole size, and can also reduce the volume of the detection tool.

[0051] A pair of waist-shaped holes 33 are provided on the detection plate 30, and the pair of waist-shaped holes 33 are symmetrically arranged with the orthogonal points of the four scale lines 31 as the center. Through the pair of waist-shaped holes 33, it is convenient to take out the detection tool.

[0052] See also Figure 2 As shown, an annular support portion 22 integrally formed with the annular plug portion 21 is connected above the annular plug portion 21, and the outer diameter of the annular support portion 22 is larger than the inner diameter of the furnace bottom electrode mounting hole. The annular support portion 22 can ensure that the cylindrical tube 10 is vertically supported on the furnace bottom electrode mounting hole, which can improve the stability of the detection tool.

[0053] The ring member 20 is sleeved on the outer edge of the bottom of the cylindrical tube 10 by glue, and the detection plate 30 is covered on the top of the cylindrical tube 10 by glue. That is to say, the ring member 20 and the detection plate 30 are bonded to the cylindrical tube 10 by glue respectively.

[0054] The above-mentioned silicon core furnace electrode centering detection tool also includes a positioning plate 40 with a rectangular structure. A circular hole is opened in the middle of the positioning plate 40, and its four corners are connected to the detection plate 30 by screws (not shown in the figure). The circular hole takes the orthogonal point of the four scale lines 31 as the center of the circle, and its hole diameter is equal to the outer diameter of the cylindrical barrel 10. The outer edge of the top of the cylindrical barrel 10 is bonded to the positioning plate 40 at the circular hole. That is to say, through the positioning plate 40 with a circular hole, when the detection plate 30 is bonded to the cylindrical barrel 10, the four scale lines 31 can be just orthogonal to the axis of the cylindrical barrel 10, thereby reducing the dimensional error in the assembly process of the detection tool, thereby ensuring the accuracy of the structure of the detection tool itself.

[0055] In this embodiment, the cylindrical tube 10, the annular member 20, the detection plate 30 and the positioning plate 40 are all made of transparent acrylic material. The transparent acrylic material is convenient for personnel to observe and judge.

[0056] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
