Description

Technical Field

[0001] This utility model relates to the field of holding device technology, specifically an electric furnace electrode holding device for producing low-carbon manganese silicon alloy. Background Technology

[0002] Low-carbon manganese silicon alloy is an important ferroalloy material, composed of manganese, silicon, iron, and small amounts of carbon and other elements. It is a widely used and high-volume ferroalloy. The production of low-carbon manganese silicon alloy requires the use of an electric furnace, which is a heating furnace that converts electrical energy into heat to heat the workpiece. The electrodes in the electric furnace play the role of converting electrical energy into heat energy, and the electrodes in the electric furnace need to be fixed by electrode holders.

[0003] Chinese Patent Publication No. CN221123024U describes an electrode holder for an electric furnace. By setting up a ring, flow channel, water inlet pipe, return pipe, sleeve, piston block, slide rod, and clamping block, it achieves the effect of automatically tightening as the electric furnace electrode is used, holding and fixing the electrode, while also cooling the electrode holder to prevent high-temperature deformation and damage, and greatly extending its service life.

[0004] Although the aforementioned patent can achieve the effect of the clamping blocks moving accordingly as the electrode diameter decreases, thus always holding the electric furnace electrode in place, during the electrode replacement process, even if all the coolant in the flow channel is drained, the clamping blocks are difficult to return to their initial positions. The clamping blocks need to be manually returned to their original positions. Since the heat released by the electrode during use is transferred to the ring, multiple clamping blocks need to wait for the clamping blocks to cool down before they can be manually returned to their original positions. Therefore, it is very time-consuming and delays the production of low-carbon manganese silicon alloy. Utility Model Content

[0005] The purpose of this invention is to provide an electric furnace electrode holder for producing low-carbon manganese silicon alloys, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric furnace electrode holder for producing low-carbon manganese silicon alloy includes a ring. Multiple clamping mechanisms for clamping and fixing the electrode are arranged at equal angles on the inner wall of the ring. A flow channel is formed inside the ring, with fixed connecting pipes penetrating both ends of the inner bottom surface of the flow channel. Each clamping mechanism includes a telescopic member fixedly connected to the inner wall of the ring. A clamping plate is detachably connected to one end of the telescopic member. Sleeves are fixedly connected to both sides of the telescopic member on the inner wall of the ring at corresponding positions. A sleeve rod, fixedly connected to the clamping plate at the corresponding position, is slidably sleeved inside the sleeve. Springs are fixedly connected to both ends of the clamping plate and the inner wall of the ring on the outer sides of the sleeves at corresponding positions.

[0008] Furthermore, the inner wall of the ring has a through hole corresponding to the telescopic component, the telescopic component includes a sleeve fixedly connected to the inner wall of the ring, a piston is slidably sleeved inside the sleeve, and a connecting rod is fixedly connected to one end of the piston.

[0009] Furthermore, a fixing block is fixedly connected to one side of the clamping plate, and an installation block is fixedly connected to one end of the connecting rod. The installation block and the fixing block at the corresponding position are fixedly connected by bolts.

[0010] Furthermore, a one-way valve is fixedly connected to the outer wall of one of the connecting pipes.

[0011] Furthermore, a pressure sensor is fixedly connected to the outer wall of another connecting pipe, and a solenoid valve is fixedly connected to the outer wall of the connecting pipe located at the pressure sensor.

[0012] Furthermore, the bottom surface of the ring is fixedly connected to a water outlet pipe that communicates with the flow channel, and the outer wall of the water outlet pipe is fixedly connected to a switch valve.

[0013] Furthermore, both the connecting pipe and the water outlet pipe are made of metal.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By releasing the coolant in the flow channel, the clamp can automatically return to its original position under the elastic action of the two springs at the corresponding positions, eliminating the need for manual return of the clamp. Furthermore, when replacing a new electrode, there is no need to wait for the clamp to cool down, thus saving time and improving the production efficiency of low-carbon manganese silicon alloy.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the present invention, an electric furnace electrode holder for producing low-carbon manganese silicon alloy includes a ring 1. The inner wall of the ring 1 is provided with a plurality of clamping mechanisms 2 for clamping and fixing the electrode at equal angles. The inner wall of the ring 1 is provided with a flow channel 11, and the two ends of the inner bottom surface of the flow channel 11 are both penetrated by fixed connecting pipes 12. The clamping mechanism 2 includes a telescopic member 21 fixedly connected to the inner wall of the ring 1. One end of the telescopic member 21 is detachably connected to a clamping plate 22. The inner wall of the ring 1 and the telescopic member 21 at the corresponding position are both fixedly connected to sleeves 23 on both sides. The sleeves 23 are slidably sleeved with a sleeve rod 24 fixedly connected to the clamping plate 22 at the corresponding position. The two ends of the side of the clamping plate 22 and the inner wall of the ring 1 and the outer side of the sleeve 23 at the corresponding position are both fixedly connected to springs 25.

[0023] Specifically, firstly, one of the connecting pipes 12 is connected to an external high-pressure pump. Then, the electrode is inserted between multiple clamping plates 22. The high-pressure pump forces coolant into the flow channel 11. As more and more coolant is injected into the flow channel 11, the pressure within it increases, causing the telescopic component 21 to move the corresponding clamping plate 22. The moving plate's clamping plate 22 then stretches the two springs 25 at their corresponding positions until the multiple clamping plates 22 tightly clamp and fix the electrode. Since the electrode diameter decreases during use, the pressure within the flow channel 11 changes. Therefore, the high-pressure pump needs to continuously inject coolant into the flow channel 11 to maintain the pressure of the coolant within the flow channel 11, ensuring the clamping plates 22 firmly hold the electrode in place. When it is necessary to replace the electrode, the coolant in the flow channel 11 is first released. At this time, the pressure in the flow channel 11 begins to decrease, and the clamping plate 22 returns to its original position under the elastic action of the two springs 25 at the corresponding positions. Then, the newly replaced electrode is inserted between the clamping plates 22, and the coolant is injected into the flow channel 11 again by a high-pressure pump until the clamping plates 22 clamp and fix the newly replaced electrode. By releasing the coolant in the flow channel 11, the clamping plate 22 can automatically return to its original position under the elastic action of the two springs 25 at the corresponding positions. There is no need to manually return the clamping plate 22 to its original position. Moreover, when replacing the new electrode, there is no need to wait for the clamping plate 22 to cool down, which can save time and improve the production efficiency of low carbon manganese silicon alloy.

[0024] Example 1

[0025] like Figure 3 and Figure 4 As shown, in this embodiment, a through hole 13 is provided through the inner wall of the ring 1 at the location corresponding to the telescopic member 21. The telescopic member 21 includes a sleeve 211 fixedly connected to the inner wall of the ring 1. A piston 212 is slidably sleeved inside the sleeve 211. A connecting rod 213 is fixedly connected to one end of the piston 212. A fixing block 26 is fixedly connected to one side of the clamping plate 22. An installation block 214 is fixedly connected to one end of the connecting rod 213. The installation block 214 and the fixing block 26 at the corresponding position are fixedly connected by bolts.

[0026] In this embodiment, the coolant can be injected into the flow channel 11 by the operation of the high-pressure pump. As the pressure in the flow channel 11 gradually increases, a portion of the coolant enters the sleeve 211 and pushes the piston 212 inside it to move. The moving piston 212 can drive the clamping plate 22 to move through the connecting rod 213, thereby clamping and fixing the electrode of the clamping plate 22. The mounting block 214 is fixedly connected to the fixing block 26 at the corresponding position by bolts, so that the clamping plate 22 can be replaced.

[0027] Example 2

[0028] like Figure 2As shown, in this embodiment, a one-way valve 18 is fixedly connected to the outer wall of one of the connecting pipes 12, a pressure sensor 16 is fixedly connected to the outer wall of the other connecting pipe 12, a solenoid valve 17 is fixedly connected to the outer wall of the connecting pipe 12 located at the pressure sensor 16, a water outlet pipe 14 communicating with the flow channel 11 is fixedly connected to the bottom surface of the ring 1, and a switch valve 15 is fixedly connected to the outer wall of the water outlet pipe 14. Both the connecting pipe 12 and the water outlet pipe 14 are made of metal.

[0029] In this embodiment, the pressure sensor 16, solenoid valve 17, and high-pressure pump are electrically connected to an external controller. The pressure pump is connected to a connecting pipe 12 with a one-way valve 18. When coolant is poured into the flow channel 11, the switch valve 15 is first closed, and then coolant is poured into the flow channel 11 through the pressure pump until multiple clamps 22 clamp the electrode. Since the diameter of the electrode will become smaller and smaller during use, the pressure in the flow channel 11 will decrease. When the pressure sensor 16 detects that the pressure in the flow channel 11 is insufficient, it will control the pressure pump to start through the controller to pour coolant into the flow channel 11 to pressurize it until the pressure reaches a constant value again, so that multiple clamps 22 always clamp and fix the electrode. The pressure in the flow channel 11 can be manually controlled by the switch valve 15 so that the staff can adjust the pressure in the flow channel 11 according to the actual situation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
