Description

Technical Field

[0001] The utility model relates to the technical field of industrial electric furnaces, and particularly relates to a short net device for submerged arc furnace smelting. Background Art

[0002] Pyrometallurgy is the oldest and most commonly used method for extracting metals. Its principle is to convert electric energy into a low-voltage and high-current form by passing a high voltage and small current through an electric furnace transformer and input it into the smelting electric furnace. The combined conductor carrying this high current is called a short net. Currently, for medium and small ferroalloy refining electric furnaces and brown fused alumina smelting electric furnaces, their short nets are designed and calculated according to the requirements of the electric furnace process parameters with reference to relevant specifications and manuals, and appropriate large-section conductors are selected. The specific method is to connect the phases in a triangle at the low-voltage side of the electric furnace transformer and connect them one-to-one to the electric furnace electrodes through large-section conductors to input electric energy into the electric furnace.

[0003] The existing short net flexible connection device is used to connect the transformer and the electrode through a cold water compensator. However, the existing short net flexible connection device is troublesome to connect and replace. At the same time, the vibration generated by the high current can damage the connection posts on the transformer side, and its service life is short. Therefore, a short net device for submerged arc furnace smelting is proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] Please refer to Figures 1-3, A short-circuit busbar device for submerged arc furnace smelting, including a transformer outgoing terminal 1, a water pipe 9 connected to the outer wall of the transformer outgoing terminal 1, and a first copper splint 8 and a second copper splint 10 installed on the water pipe 9. Among them, there is flowing water inside the water pipe 9 for cooling the transformer outgoing terminal 1. A busbar 4 is movably connected between the first copper splint 8 and the second copper splint 10. Among them, both ends of the busbar 4 are respectively located at the tops of the first copper splint 8 and the second copper splint 10. Installation frames 7 are vertically installed on both the first copper splint 8 and the second copper splint 10. Among them, the installation frame 7 is in an inverted L shape, and elastic positioning components are arranged on the inner top walls of the two installation frames 7. The two elastic positioning components are respectively clamped with both ends of the busbar 4 for fixing the busbar 4. Among them, the elastic positioning component includes a positioning spring 5 fixedly installed on the inner top wall of the installation frame 7 and a positioning rod 6 arranged inside the positioning spring 5. Among them, one end of the top of the positioning spring 5 is fixedly connected to the inner top wall of the installation frame 7, and the other end is fixedly connected to the side wall of the positioning rod 6. Among them, one end of the bottom of the positioning rod 6 is clamped with the busbar 4. Among them, a card slot 14 is opened on the upper surface of the busbar 4. Among them, the bottom of the positioning rod 6 extends into the inside of the card slot 14 and is clamped with the busbar 4. Thus, through the elastic force of the positioning spring 5 stretching, the positioning rod 6 can maintain a downward movement trend until the positioning rod 6 extends into the inside of the card slot 14 and is clamped with the busbar 4. Among them, a hemispherical body 15 is fixedly installed at the bottom of the positioning rod 6. Among them, the hemispherical body 15 is clamped with the card slot 14. Through the hemispherical body 15, the positioning rod 6 is clamped with the busbar 4 in a way that avoids scratching the busbar 4, thus achieving the effect of including the busbar 4 during the installation process. Among them, the top of the positioning rod 6 extends above the installation frame 7 and is fixedly installed with a handle 2. Thus, when the busbar 4 needs to be disassembled, the handle 2 can be pulled upward at the top of the installation frame 7 to release the clamping relationship between one end of the bottom of the positioning rod 6 and the busbar 4, and then the busbar 4 can be disassembled from between the first copper splint 8 and the second copper splint 10, thus achieving the effect of facilitating the disassembly of the busbar 4.

[0026] In this embodiment, a limiting groove 11 is vertically opened on the inner wall of the installation frame 7. A connecting rod 12 is horizontally installed on the side wall of the positioning rod 6, and a limiting block 13 is installed at the end of the connecting rod 12 away from the positioning rod 6. Among them, the limiting block 13 is slidably connected with the limiting groove 11. By means of the sliding connection between the limiting block 13 and the limiting groove 11, the positioning rod 6 can only move in the vertical direction through the elastic force of the positioning spring 5 stretching and will not shift, thus achieving the effect of limiting the movement mode of the positioning rod 6, and further enabling the positioning rod 6 to be easily clamped with the busbar 4, improving the installation speed.

[0027] In this embodiment, friction pads 3 are installed on the upper surfaces of the first copper clamping plate 8 and the second copper clamping plate 10. Among them, both ends of the bottom of the busbar 4 are frictionally connected to the two friction pads 3. Through the two friction pads 3, the busbar 4 can be relatively stably placed between the first copper clamping plate 8 and the second copper clamping plate 10 before being clamped with the positioning rod 6, thereby facilitating the clamping of the positioning rod 6 and the busbar 4 and further improving the installation efficiency of the busbar 4.

[0028] Working principle: When the busbar 4 needs to be installed, pull up the two handles 2, then place the busbar 4 between the first copper clamping plate 8 and the second copper clamping plate 10 from the front side, and then release the two handles 2, so that the two positioning rods 6 move downward through the elastic force of the two positioning springs 5 stretching until they extend into the two card slots 14 and are clamped with the busbar 4, thus achieving the effect of facilitating the installation of the busbar 4.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
