Description

Technical Field

[0001] This utility model relates to the field of high-temperature purification furnace cleaning technology, and more specifically, to a tool for cleaning graphite electrodes in a high-temperature graphitization furnace. Background Technology

[0002] High-temperature graphite furnaces are a crucial heat treatment process for carbon-carbon composite materials. This process not only arranges randomly layered carbon atoms into an ordered graphite crystal structure but also facilitates high-temperature purification, allowing impurities other than carbon to be expelled with the gas flow in an inert gas environment at 2400℃. However, most high-temperature graphitization furnaces on the market use copper electrodes, graphite electrodes, and graphite heating rods. The copper electrodes are connected to water-cooled pipes outside the furnace shell, and their temperature is generally not high. The graphite heating rods are located inside the furnace, and to insulate them from the furnace shell and insulation layer, most use air insulation. Air insulation means that the inert gas, carrying impurities generated during high-temperature treatment, enters this confined space. Over time, these impurities adhere to the graphite electrodes, reducing insulation resistance, causing the graphite heating rods to become conductive with the insulation layer, and triggering an alarm. The usual solution is to completely remove, clean, and reinstall the graphite heating rods, graphite electrodes, and copper electrodes, which is time-consuming and labor-intensive. To address these issues, a solution is proposed below. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-temperature graphitization furnace graphite electrode cleaning tool that can conveniently clean the electrode without disassembling it.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A tool for cleaning graphite electrodes in a high-temperature graphitization furnace includes a cleaning rod. A guide rail, which is arc-shaped, is provided at the bottom of the cleaning rod. A connector, which can be fixed at any position on the guide rail, is slidably mounted on the guide rail. The connector is fixedly connected to the bottom of the cleaning rod. A linear motion unit is provided at the other end of the guide rail. The output end of the linear motion unit is fixedly connected to one end of the bottom of the guide rail. The linear motion unit includes a mounting frame, a drive block, and a moving rod. The drive block is fixed on the mounting frame, and the moving rod is slidably engaged with the mounting frame. The drive block and the moving rod are connected by a transmission mechanism. One end of the moving rod is fixedly connected to the bottom of the guide rail.

[0006] Preferably, the drive block includes a motor, push rods, and an eccentric drive disk. The motor is fixedly mounted on the mounting bracket, the eccentric drive disk is mounted on the output shaft of the motor, and there are two push rods mounted on the same side of the moving rod and arranged along the axial direction of the push rod. The eccentric drive disk is rotatably arranged between the two push rods.

[0007] Preferably, the connector includes a connecting rod, a nut, and a sliding groove. The sliding groove is formed on the guide rail and is arc-shaped. One end of the connecting rod is fixed to the bottom of the cleaning rod, and the other end of the connecting rod passes through the sliding groove and is slidably engaged. The connecting rod is a threaded rod, and the nut and the connecting rod are threadedly engaged. The nut and the cleaning rod are located on opposite sides of the guide rail.

[0008] Preferably, the moving rod has a stabilizing groove along the axial direction, and a stabilizing rod is slidably disposed inside the stabilizing groove. The stabilizing rod is fixed to one side of the eccentric drive disk, and the stabilizing rod and the output shaft of the motor are concentric.

[0009] Preferably, the mounting bracket is provided with a movable hole, and the movable rod passes through the movable hole and is slidably engaged.

[0010] Preferably, the angle of the groove is 180 degrees.

[0011] Preferably, the eccentric drive disk is a rounded triangle.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This solution uses a cleaning rod to clean the electrode. The linear motion unit can move the cleaning rod up and down, cleaning the electrode surface by rubbing the cleaning rod up and down. This avoids the hassle of removing the electrode. The design of the guide rail and connectors allows the position of the cleaning rod to be adjusted, thus cleaning different parts of the electrode. It is simple to use and improves cleaning efficiency.

[0014] 2. The motor is used to drive the eccentric drive disc to rotate. The distance between the rotating shaft of the eccentric drive disc and the edge position will change, thereby applying force to the push rod. The push rod drives the moving rod to move, thereby realizing the movement of the cleaning rod.

[0015] Third, the threaded connection between the nut and the connecting rod facilitates adjustment and makes operation simple. Attached Figure Description

[0020] Example 1:

[0021] Please see Figure 1-2 A tool for cleaning graphite electrodes in a high-temperature graphitization furnace includes a cleaning rod 1. The cleaning rod 1 can be any one of the following: a tapered metal wire rod, a rod body with 40-400 grit sandpaper, nylon, ceramic fiber whetstone, or stainless steel metal brush. A guide rail 2 is provided at the bottom of the cleaning rod 1. The guide rail 2 is arc-shaped. A connector 3 is slidably provided on the guide rail 2 and can be fixed at any position on the guide rail 2. The connector 3 includes a connecting rod 11, a nut 12, and a sliding groove 13. The sliding groove 13 is formed on the guide rail 2 and is arc-shaped with an arc angle of 180 degrees. One end of the connecting rod 11 is fixed to the bottom of the cleaning rod 1, and the other end of the connecting rod 11 passes through the sliding groove 13 and is slidably engaged. The connecting rod 11 is a threaded rod. The nut 12 is threadedly engaged with the connecting rod 11, and the nut 12 and the cleaning rod 1 are located on opposite sides of the guide rail 2.

[0022] By adjusting the position between the nut 12 and the cleaning rod 11 through the threaded engagement of the nut 12 and the connecting rod 11, the guide rail 2 is clamped and the position between the guide rail 2 and the cleaning rod 1 is fixed. At the same time, by loosening the nut 12 and the connecting rod 11, the cleaning rod 1 can be moved around the slide groove 13, thereby adjusting the cleaning of different positions on the electrode by the cleaning rod 1.

[0023] A linear motion unit 4 is provided at the other end of the guide rail 2. The linear motion unit 4 includes a mounting frame 5, a drive block 6, and a moving rod 7. A moving hole 16 is installed on the mounting frame 5. The moving hole 16 has a rectangular cross-section. The moving rod 7 passes through the moving hole 16 and slides with the mounting frame 5. The moving rod 7 and the moving hole 16 are mutually adapted. One end of the moving rod 7 is fixedly connected to the bottom of the guide rail 2. The drive block 6 includes a motor 8, a push rod 9, and an eccentric drive disk 10. The motor 8 is fixedly installed on the mounting frame 5. The output end of the motor 8 passes through the mounting frame 5, and the output end of the motor 8 is connected to the mounting frame. 5. Rotary engagement: The eccentric drive disk 10 is mounted on the output shaft of the motor 8. The eccentric drive disk 10 is a rounded triangle. There are two push rods 9. The two push rods 9 are mounted on the side of the moving rod 7 near the mounting bracket 5, and the two push rods 9 are arranged along the axial direction of the push rods 9. The eccentric drive disk 10 is rotatably arranged between the two push rods 9. The moving rod 7 has a stabilizing groove 14 along the axial direction. A stabilizing rod 15 is slidably arranged inside the stabilizing groove 14. The stabilizing rod 15 is fixed on one side of the eccentric drive disk 10, and the stabilizing rod 15 is concentric with the output shaft of the motor 8.

[0024] Working principle:

[0025] In use, the motor 8 drives the eccentric drive disk 10 to rotate, which in turn pushes the push rod 9 near the cleaning rod 1 to move. This push rod 9 then moves the moving rod 7 upward. When the farthest point of the eccentric drive disk 10 passes the push rod 9, the moving rod 7 returns to its original position under its own gravity. This process repeats, thus achieving the up-and-down reciprocating motion of the moving rod 7. The moving rod 7 then drives the guide rail 2 to move, which in turn causes the guide rail 2 and the cleaning rod 1 to move up and down. The up-and-down reciprocating cleaning rod 1 cleans the surface of the electrode by friction, avoiding the hassle of cleaning the electrode.

[0026] Loosening nut 12 removes the pressure between nut 12 and guide rail 2, allowing connecting rod 11 to slide inside guide groove, thereby adjusting the angle of cleaning rod 1 on the horizontal plane. This allows it to adapt to different angles on the side of the electrode, enabling all-round cleaning of the electrode and avoiding cleaning dead corners. At the same time, the threaded engagement between nut 12 and connecting rod 11 makes it easy to use.
