Description

Technical Field

[0001] This utility model relates to the technical field of electric furnace smelting equipment, specifically an adjustable pole center distance device for a DC electric furnace. Background Technology

[0002] In existing technologies, during electric furnace smelting, the electrode center distance has a significant impact on the furnace's melting efficiency and quality. Appropriately adjusting the electrode center distance can improve the furnace's operating efficiency. The electrodes are surrounded by a support frame, platform plate, rubber plate, and connecting plate. The platform plate is welded above the support frame, and the rubber plate is installed at the electrode holes on the platform plate via the connecting plate, sealing the gap between the platform and the electrodes. A drawback is that the spacing between the two sets of electrodes cannot be adjusted, leading to unstable furnace operation. Utility Model Content

[0003] The purpose of this invention is to provide a DC electric furnace pole center distance adjustable device that facilitates adjustment of the electric furnace pole center distance and improves the working efficiency of the electric furnace, in order to address the above-mentioned shortcomings.

[0004] The technical solution of this utility model is: an adjustable electrode center distance device for a DC electric furnace, characterized in that it consists of a left electrode support platform and a right electrode support platform, which are completely symmetrical; the left electrode support platform includes a support frame, on which two opposing platform plates are fixed, and two sets of two opposing pressure plates are connected to two stacked buffer rubber plates and rubber sheets; the platform plate 4 has electrode post holes slightly larger than the electrode diameter and long bolt holes in the middle, and is fixed on the support frame by bolts; the buffer rubber plates and rubber sheets have electrode post holes that fit with the electrodes in the middle, and the buffer rubber plates are stacked on top of the rubber sheets, and the two are fixed on the platform plate together by connecting plates and bolts.

[0005] The advantages of this invention are: when adjusting the electrode center distance of the electric furnace, the electrode support platform does not need to be modified or rebuilt, and can be adjusted on-site, which greatly reduces the workload and saves modification costs.

[0006] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0010] Figure 4 yes Figure 2 Enlarged view of point I.

[0011] Figure 5 This is a simplified diagram of the connecting plate.

[0012] Figure 6 This is a simplified diagram of the platform board. Detailed Implementation

[0013] See Figure 1-6 The component names are as follows: left electrode support platform 1, right electrode support platform 2, support frame 3, platform plate 4, connecting plate 5, buffer rubber plate 6, rubber plate 7, long bolt hole 8, cylinder hole 9.

[0014] See Figure 1-6 An adjustable electrode center distance device for a DC electric furnace comprises a left electrode support platform 1 and a right electrode support platform 2. The left electrode support platform 1 and the right electrode support platform 2 are completely symmetrical. The original platform plate is split into two symmetrical pieces, and the round holes of the fixing bolts are changed to elongated holes. After loosening the bolts, the platform plate can slide on the support frame 3 to change the position of the electrode holes. The left electrode support platform 1 includes a support frame 3, on which four platform plates 4 are fixed in pairs. The two platform plates 4 are connected and fixed by a connecting plate 5 and bolts. There are two sets of two-piece stacked buffer rubber plates 6 and rubber plates 7 on the platform. The platform plate 4 has electrode post holes slightly larger than the diameter of the electrode and elongated bolt holes 8 processed in the middle, and is fixed on the support frame 3 by bolts. The buffer rubber plates 6 and rubber plates 7 have electrode post holes that fit with the electrode in the middle. The buffer rubber plates 6 are stacked on top of the rubber plates 7, and the two are fixed on the platform plate 4 together by bolts. When it is necessary to change the pole center distance, the lateral pole center distance can be changed by moving the left electrode support platform 1 and the right electrode support platform 2 left and right; the longitudinal pole center distance can be changed by moving the platform plate 4 up and down. Figure 1 The four large circles in the middle are electrode holes, through which the electrodes pass.

[0015] The left electrode support platform 1 consists of a support frame 3, four platform plates 4, four connecting plates 5, two buffer rubber plates 6, and two rubber plates 7. When the electrode center distance needs to be adjusted, the platform center distance can be adjusted by loosening the bolts of the platform plate 4 and adjusting the position of the platform plate 4.

[0016] The cylinder hole 9 on the support frame 3 is changed to an elongated hole, allowing the cylinder to slide and change position within the hole. The function of the cylinder is to drive the electrode lifting system to move up and down. During the smelting process, the electrode is continuously consumed, requiring it to descend to replenish the consumed material.

[0017] In the electric furnace smelting process, the main function of this device is to adjust the distance between two adjacent sets of electrodes to ensure the usability of the electrodes during furnace operation. By adjusting the distance between two adjacent sets of electrodes, the modification or reconstruction of the electrode adjustment device is avoided when the electrode center distance of the electric furnace changes, greatly reducing the workload and saving modification costs.

[0018] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
