Description

Technical Field

[0001] The utility model relates to the technical field of electric furnace tapping for calcium carbide production, and particularly relates to a reactor bank for burning holes during the tapping of an electric furnace for calcium carbide production. Background Art

[0002] During the production process of an electric furnace for calcium carbide, burning holes during tapping is one of the key technological processes. However, traditional methods for burning holes often have problems such as unstable current and low success rate of burning holes, which seriously restrict the production efficiency and economic benefits of the electric furnace for calcium carbide. Therefore, how to optimize the method for burning holes in the electric furnace for calcium carbide and improve the success rate of burning holes has become an urgent problem to be solved in the industry.

[0003] The current electric furnace tapping hole burning system for calcium carbide is divided into two types. The first type burns holes by installing a piercing transformer separately, and the second type burns holes by additionally leading out a piercing copper bar from the secondary short circuit of the transformer corresponding to its electrode. Among them, the method of additionally leading out a piercing copper bar from the secondary short circuit of the transformer corresponding to its electrode has the highest usage ratio for burning holes.

[0004] During normal production, the gear position of the furnace transformer is relatively high (gear positions 18 - 21, secondary voltage 318 - 332V). Since the current of the piercer is determined by the operating gear position of the furnace transformer and cannot be adjusted separately, during the piercing operation, the piercing current fluctuates within the range of 3100 - 7400A. Due to the high voltage supplied by the furnace transformer to the piercer, resulting in a large piercing current, it is impossible to well control the shape of the burned hole, increasing the difficulty of furnace hole maintenance operations. At the same time, during the hole burning process, it will interfere with the electrode current during normal operation, causing fluctuations in the electrode current, electrode position, load, and increasing the difficulty of central control operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a reactor bank for burning holes during the tapping of an electric furnace for calcium carbide, so as to solve the problem that it is easy to interfere with the electrode current when the piercing current is large.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A reactor bank for burning holes during the tapping of an electric furnace for calcium carbide, comprising a mounting plate, on which two or more reactors are arranged. The reactors are fixedly connected to the top surface of the mounting plate through a mounting mechanism, and two adjacent reactors are connected in series.

[0008] A further technical solution is that the installation mechanism includes an installation cross bar which is fixedly installed on the top surface of the installation plate. At both ends of the same side of the installation cross bar, a fixed cross bar and a movable cross bar are respectively provided. The fixed cross bar and the movable cross bar are arranged in parallel. The fixed cross bar is fixedly connected to the installation cross bar.

An activity plate is provided on the side surface of the support plate close to the movable cross bar. The activity plate is slidably connected to the support plate through a second adjustment component. A limiting plate is provided on one side of the bottom of the activity plate far from the installation cross bar. The limiting plate is slidably connected to the activity plate through a third adjustment component.

[0009] A further technical solution is that the first adjustment component includes a first lead screw. A first activity groove is provided on the side surface of the installation cross bar. A first fixed hole communicating with the first activity groove is provided on the end surface of the installation cross bar. One end of the first lead screw passes through the first fixed hole and is rotatably connected to the closed end of the first activity groove. A first matching block is threadedly connected to the first lead screw. The side surface of the first matching block contacts the groove wall of the first activity groove. The first matching block is fixedly connected to the end of the movable cross bar.

[0010] A further technical solution is that the second adjustment component includes a second lead screw. A second activity groove is provided on the side surface of the support plate close to the activity plate. A second fixed hole communicating with the second activity groove is provided on the top surface of the support plate. One end of the second lead screw passes through the second fixed hole and is rotatably connected to the closed end of the second activity groove. A second matching block is threadedly connected to the second lead screw. The side surface of the second matching block contacts the groove wall of the second activity groove. The second matching block is fixedly connected to the side surface of the activity plate.

[0011] A further technical solution is that the third adjustment component includes a third lead screw. A third activity groove is provided on the bottom surface of the activity plate.

One end of the third lead screw passes through the third fixed hole and is rotatably connected to the closed end of the third activity groove. A third matching block is threadedly connected to the third lead screw. The side surface of the third matching block contacts the groove wall of the third activity groove. The third matching block is fixedly connected to the top of the limiting plate.
