Description

Technical Field

[0001] This utility model relates to the field of self-baking electrode technology, specifically to a self-baking electrode with hollow vaporization nozzles. Background Technology

[0002] Self-baking electrodes are made from anthracite, coke, asphalt, and tar as raw materials, which are processed into an electrode paste at a certain temperature. The electrode paste is then filled into an electrode shell already installed on an electric furnace and sintered to form the electrode. Due to its simple process and low cost, self-baking electrodes are widely used in ferroalloy electric furnaces and calcium carbide furnaces. Traditional self-baking electrodes are mostly solid, with a small number being improved to hollow electrodes. However, the purpose of this hollow electrode design is to allow the discharge of organic waste gas generated after the electrode paste is heated.

[0003] A Chinese utility model patent with authorization announcement number CN201608934U discloses a hollow self-baking electrode. The hollow self-baking electrode has a central steel tube with vent holes. The vent holes can smoothly discharge the volatilized electrode paste, thereby improving the sintering quality of the electrode paste. The main purpose of the hollow self-baking electrode is to discharge the organic waste gas generated after the motor paste is heated.

[0004] However, neither the solid nor the hollow self-baking electrode mentioned above can achieve the function of blowing air into the furnace. Therefore, a self-baking electrode is invented that can blow air into the liquid in the furnace, which can accelerate the reaction in the furnace. Summary of the Invention

[0005] In view of this, the present invention provides a self-baking electrode with hollow gasification nozzles to solve the problem that existing electrodes cannot blow gas into the furnace to accelerate the reaction inside the furnace.

[0006] To solve the above-mentioned technical problems, the self-baking electrode with hollow gasification nozzles provided by this utility model adopts the following technical solution:

[0007] A self-baking electrode with a hollow gasification nozzle includes an outer shell, an electrode paste inside the outer shell, the electrode paste being located between an inner tube and the inner wall of the outer shell, an inner tube located at the geometric center of the outer shell, and a central hole of the self-baking electrode being formed inside the inner tube, a gas supply pipe inserted inside the central hole, one end of the gas supply pipe extending outside the central hole, and a hose sealed to the other end of the gas supply pipe outside the central hole via a connecting assembly, allowing gas in the hose to enter the furnace through the gas supply pipe.

[0008] Furthermore, the connecting assembly includes a flange one located at one end of the hose and a flange two located at one end of the air supply pipe, wherein the flange one and the flange two are fixedly connected by insulating bolts.

[0009] Furthermore, an insulating gasket is provided between flange one and flange two.

[0010] Furthermore, there is a gap between the air supply pipe and the inner wall of the central hole.

[0011] Furthermore, the inner wall of the outer shell is provided with reinforcing ribs.

[0012] Furthermore, the reinforcing ribs are arranged in a ring array at intervals on the inner wall of the outer shell.

[0013] Furthermore, the reinforcing ribs are welded to the inner wall of the outer shell.

[0014] Furthermore, the outer circumferential surface of the outer shell is symmetrically provided with lifting noses at intervals around the central hole.

[0015] The above-mentioned technical solution of this utility model has at least the following beneficial effects:

[0016] 1. By setting up an inner pipe, a gas supply pipe, a hose, and connecting components, external gas can be blown into the liquid inside the furnace. The end of the hose away from the gas supply pipe is connected to the gas source. The gas enters the gas supply pipe through the hose and then enters the self-baking electric furnace through the gas supply pipe. Since the end of the self-baking electrode without the hose is inserted into the liquid inside the self-baking electric furnace, the gas entering the self-baking electric furnace can directly enter the liquid inside the self-baking electric furnace and blow the liquid to tumble, thus accelerating the reaction inside the furnace.

[0017] 2. By setting up a connecting component, the gas supply pipe and hose can be connected together in an insulated and sealed manner. Since the self-baking electrode is charged, an insulated connecting component is used to prevent electrical conduction to other equipment.

[0018] 3. The self-baking electrode can be raised and lowered by setting a lifting nose, which makes it convenient to adjust the position of the self-baking electrode. Attached Figure Description

The end of the self-baking electrode without the hose 8 is inserted into the liquid inside the furnace. When the gas enters the liquid through the gas supply pipe 5 and blows the liquid to roll, it can promote the full reaction of various components inside the furnace.

[0032] To facilitate the up-and-down movement of the self-baking electrode, there is a gap between the gas supply pipe 5 and the inner wall of the central hole 6. The specific size of the gap can be adjusted according to the actual situation.

[0033] Furthermore, the inner wall of the outer shell 1 is provided with reinforcing ribs 3, which can strengthen and stabilize the electrode paste 2 and prevent it from breaking.

[0034] Furthermore, the reinforcing ribs 3 are arranged in a ring array at intervals on the inner wall of the outer shell 1.

[0035] More specifically, the reinforcing ribs 3 are welded to the inner wall of the outer shell 1.

[0036] To facilitate lifting and moving the self-baking electrode up and down, the outer shell 1 is symmetrically provided with lifting noses 9 at intervals around the central hole 6 on the outer peripheral surface.
