Description

Technical Field

[0001] This utility model relates to the field of electrode shell drying technology, and in particular to an electrode shell drying and rust removal device. Background Technology

[0002] The electrode shell is an important component of an electric arc furnace, primarily used for the reduction smelting of furnace charges such as ores. Its working principle involves inserting electrodes into the furnace charge, employing a submerged arc operation, and using resistance and an electric arc to heat the ore, thus reducing it. The manufacturing process of the electrode shell includes three main steps: arc plate fabrication, stiffener plate fabrication, and welding assembly, requiring multiple processes to complete.

[0003] The electrode shell is mainly made of cold-rolled steel plate. Large electrodes sometimes have steel strips or threaded steel bars welded to the ends of the ribs to enhance their load-bearing capacity. The electrode shell is relatively large, with a height of 1.5 meters, a diameter of 1.42 meters, and a single section weight of 400 kg. It is made of multiple 3 mm thick ribs and 2.5 mm thick arc plates welded together.

[0004] During the electrode shell manufacturing process, cooling water is needed to cool the weld seam. After the weld seam is completed, a lot of water stains will remain on the surface of the electrode shell. When the electrode shell is stored on site after the electrode shell is manufactured, oxidation and corrosion will occur, resulting in a large amount of rust on the surface of the electrode shell. The large amount of rust will affect the conductivity between the electrode shell and the contact element. It is necessary to manually remove the rust on the surface of the electrode shell using an angle grinder, which increases the labor intensity of the workers. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of current methods where a large amount of moisture is generated on the surface of the electrode shell after welding, which leads to rust on the electrode shell surface and affects its later use. Therefore, an electrode shell air drying and rust removal device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrode shell air drying and rust removal device includes a seam welding machine. A seam welding wheel is connected to the side of the seam welding machine via a conductive post. An electrode shell is disposed on one side of the seam welding wheel. A pipe assembly is disposed on the side of the seam welding wheel. The pipe assembly is connected to an air supply system. The pipe assembly includes an air jet pipe with multiple air jet nozzles disposed on it. The air jet pipe is located below the electrode shell, and the air jet nozzles are disposed corresponding to the electrode shell above it.

[0008] By using air jet pipes and nozzles, the welded areas of the electrode shell are air-dried, preventing rust on the outer wall of the electrode shell during later storage. This reduces the labor intensity of workers, extends the lifespan of the electrode shell, and lowers maintenance costs and replacement frequency.

[0009] Preferably, the piping assembly further includes a connecting pipe, which is connected to the side wall of the seam welding machine via a bracket, and is connected to the jet pipe. A solenoid valve and a ball valve are connected to the connecting pipe.

[0010] Preferably, a connecting box is provided below the jet pipe, and a support column is fixed at the bottom of the connecting box. A groove is provided on the support column, and an adjusting plate is hinged in the groove. Two support rods are connected to the upper surface of the adjusting plate, and the upper ends of the two support rods are respectively connected to the lower surface of the jet pipe.

[0011] Preferably, a turntable is connected to the side wall of the connecting box, a motor is connected to the side wall of the connecting box, the output shaft of the motor is connected to the turntable, and a push rod is eccentrically arranged on the turntable, with the upper end of the push rod hinged to the lower surface of the adjusting plate.

[0012] The arrangement of the turntable and push rod changes the angle of the adjustment plate, which in turn changes the angle of the jet pipe, thus changing the angle of the jet nozzle. This ensures even spraying onto the hot outer surface of the electrode shell, resulting in fast drying and preventing uneven drying in certain areas.

[0013] Preferably, a telescopic rod is hinged inside the connecting box, with the movable section of the telescopic rod hinged to the lower surface of the adjusting plate and the fixed section of the telescopic rod hinged to the lower surface of the connecting box.

[0014] Preferably, the air supply system includes an air compressor station, which is connected to a connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the setting of the jet pipe and jet nozzle blows away the water stains on the surface of the electrode shell and uses compressed air to dry the water stains on the surface of the shell, thereby achieving the purpose of drying the water stains on the electrode shell and reducing the labor intensity of the workers. At the same time, by setting the adjustment plate, the angle of the jet pipe can be adjusted, thereby changing the position and angle of the air outlet and avoiding uneven drying in some areas.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Reference Figures 1-2 An electrode shell air-drying and rust-removing device includes a seam welding machine 8. A seam welding wheel 6 is connected to the side of the seam welding machine 8 via a conductive post 7. An electrode shell is disposed on one side of the seam welding wheel 6. The electrode shell is placed on a seam welding trolley and transported to one side of the seam welding machine 8 during seam welding. The seam welding wheel 6 then limits the position of the electrode shell to be welded. A pipe assembly is disposed on the side of the seam welding wheel 6 and is connected to an air supply system. The pipe assembly includes an air jet pipe 1 with multiple air nozzles 3. The air jet pipe 1 is located below the electrode shell, and the air nozzles 3 are connected to the upper... The square electrode shell is correspondingly configured, and the air supply system includes an air compressor station connected to the connecting pipe 5. The air compressor station supplies air, which is delivered to the welded position of the electrode shell through the jet pipe 1 and jet nozzle 3. The compressed air dries the water stains on the shell surface, thereby achieving the purpose of drying the electrode shell and removing the water stains left on the electrode shell surface during the welding process. This prevents the electrode shell surface from rusting, enhances the conductivity between the electrode shell and the contact elements, and extends the storage period of the electrode shell, reducing oxidation corrosion caused by moisture, thus effectively preventing the electrode shell surface from rusting. Preventing rust can improve the conductivity between the electrode shell and the contact elements, reduce the increase in resistance caused by the oxide layer, and ensure the normal operation of the calcium carbide furnace.

[0022] Reference Figures 1-2 The piping assembly also includes a connecting pipe 5, which is connected to the side wall of the seam welding machine 8 via a bracket 10. The bracket 10 is set with clamps to fix the connecting pipe 5 to the outer shell of the seam welding machine 8. The connecting pipe 5 is connected to the jet pipe 1. A solenoid valve 9 and a ball valve 11 are connected to the connecting pipe 5. The ball valve 11 controls the opening and closing of the pipe. In use, the solenoid valve 9 is connected to the frequency converter on the seam welding machine 8. When the seam welding machine 8 starts to work and performs seam welding, the current on the frequency converter increases. At this time, the solenoid valve 9 closes, and the connecting pipe 5 starts to supply air. Thus, when the seam welding machine 8 performs seam welding, the connecting pipe 5 starts to supply air.

[0023] Reference Figures 1-2 A connecting box 16 is located below the jet pipe 1. A support column 13 is fixed to the bottom of the connecting box 16. A groove is provided on the support column 13, and an adjusting plate 4 is hinged within the groove. The angle of the adjusting plate 4 can be adjusted. Two support rods 2 are connected to the upper surface of the adjusting plate 4, and the upper ends of the two support rods 2 are respectively connected to the lower surface of the jet pipe 1, supporting the jet pipe 1. A turntable 15 is connected to the side wall of the connecting box 16, and a motor is connected to the side wall of the connecting box 16. The output shaft of the motor is connected to the turntable 15. A push rod 14 is eccentrically mounted on the turntable 15, and the upper end of the push rod 14 is hinged to the lower surface of the adjusting plate 4. The connecting box 16 has a telescopic rod 12 hinged inside. The movable section of the telescopic rod 12 is hinged to the lower surface of the adjusting plate 4, and the fixed section of the telescopic rod 12 is hinged to the lower surface of the connecting box 16. The connecting pipe 5 is a flexible hose. The motor controls the turntable 15 to rotate, and the turntable 15 will drive the end of the push rod 14 to move up and down together, thereby controlling the rotation of the adjusting plate 4. The angle of the adjusting plate 4 changes, and the angle of the upper jet pipe 1 changes, so that the angle of the jet nozzle 3 changes. The airflow generated by the jet nozzle 3 is evenly distributed at the seam weld, improving the moisture evaporation efficiency, accelerating the drying speed, and avoiding uneven drying in some areas.

[0024] During use, the electrode shell is transported to one side of the seam welding machine 8 by the seam welding carriage. The seam welding machine 8 begins welding. After the seam welding is completed, the seam welding carriage controls the electrode shell to rotate, rotating the welded position to the position of the air nozzle 3. The ball valve 11 is opened, and gas is then sprayed through the connecting pipe 5 and the air pipe 1, and through multiple air nozzles 3, onto the welding position of the electrode shell to blow away water stains on the electrode shell during the seam welding process. At the same time, the motor on the connecting box 16 starts to work, driving the turntable 15 to rotate. The turntable 15 pulls the adjusting plate 4 through the push rod 14. Under the action of the support column 13, the angle of the adjusting plate 4 changes, and the adjusting plate 4 begins to swing up and down. The adjusting plate 4 drives the air pipe 1 to adjust together, and the air pipe 1 drives the air nozzle 3 to change the position and angle of the air outlet, drying different positions on the electrode shell and avoiding uneven drying in some areas.
