Description

Technical Field

[0002] Electrode columns are used as two ends for inputting or outputting current in a conductive medium. One pole for inputting current is called anode or positive pole, and one pole for releasing current is called cathode or negative pole. Electrode columns include copper electrode, graphite electrode, etc. Graphite electrode refers to a high temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregate, coal tar as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. In order to ensure the smoothness of the graphite electrode surface, the surface of the graphite electrode needs to be optimized after its production, and the graphite electrode is usually polished by a grinder.

[0003] In the prior art, during the graphite electrode column grinding process, it is necessary to maintain the close contact between the graphite electrode column and the grinding component to improve the grinding effect of the graphite electrode column. Since the grinding component is always in contact with the side surface of the graphite electrode column, the long-term grinding causes the contact surface temperature of the grinding component and the graphite electrode column to be high, which not only affects the grinding quality of the graphite electrode column, but also causes the loss of the grinding component.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention absorbs the graphite powder in the air flow through the dust filter water in the dust filter box, so as to realize the water absorption and filtration of the graphite powder in the grinding process. The treated air flow goes upward along the air guide pipe into the push flow water tank. As the air pressure in the push flow water tank gradually increases, the push flow piston disc is pushed to move upward and disengage from the limit ring. When the pressure trigger disc presses against the first pressure sensor, the conveying control motor is controlled to stop running and the solenoid valve is controlled to open, so as to realize the internal pressure relief of the push flow water tank through the exhaust pipe until the push flow piston disc moves downward again and presses against the first pressure sensor. On the limit ring, the control conveying control motor is restarted at this time, and the push flow water tank is automatically filled through the automatic water supply pipe. Such cyclic control can realize the powder collection and cooling treatment during the grinding process of the graphite electrode column. The water entering the cooling guide box enters the water inlet pipe under the action of gravity, and is finally discharged from the water outlet pipe to realize the collection of cooling water. The continuous flow of water in the cooling cavity can realize the continuous cooling of the grinding roller. Combined with the air cooling effect generated by the air flow, the cooling effect of the graphite electrode column and the grinding roller during the grinding process can be greatly improved.

[0016] 2. The present invention installs a certain amount of dust filter water in the dust filter box. During the rotation of the air supply impeller, the air entering the gear air supply box enters the column polishing box along the air inlet pipe. The airflow entering the column polishing box carries the graphite powder generated during the polishing process through the air outlet pipe into the dust filter box. The graphite powder in the airflow is absorbed by the dust filter water in the dust filter box, thereby achieving water absorption and filtration of the graphite powder during the polishing process. The treated airflow flows upward out of the dust filter box. This polishing control method can achieve efficient collection of graphite powder. At the same time, in the process of collecting graphite powder, the graphite electrode column and the polishing roller are cooled by air, thereby ensuring the polishing quality of the graphite electrode column.

[0017] 3. According to the present invention, after the electrode column positioning mechanism clamping and fixing the graphite electrode column is lowered into the column polishing box until the groove limit portion and the protruding limit portion are tightly plugged into each other, the vertical guide seat is separated from the threaded structure on the conveying control screw and fits on the top of the horizontal magnetic seat, and then the telescopic cylinder is used to drive the horizontal movable seat to move horizontally until the horizontal movable seat abuts against the outer wall of the column polishing box. At this time, the axial sealing plate just fits tightly in the corresponding polishing sealed port to achieve the sealing of the polishing sealed port. In this process, after the polishing roller abuts against the peripheral side of the graphite electrode column, as the horizontal movable seat continues to move, the polishing roller gradually approaches the axial sealing plate. Under the action of the first moving rod, the elastic element is stretched by force. After the axial sealing plate is tightly fitted in the corresponding polishing sealed port, the elastic force of the elastic element causes the two relatively arranged polishing rollers to press tightly against the peripheral side of the graphite electrode column, thereby ensuring the polishing quality of the graphite electrode column.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] After the electrode column positioning mechanism 3 clamping and fixing the graphite electrode column 4 is lowered to the inside of the column grinding box 103 to complete the positioning, the vertical guide seat 301 is separated from the threaded structure on the conveying control screw 102 and fits on the top of the horizontal magnetic seat 101, and then the two relatively set grinding mechanisms 2 are moved to the specified position, so that the two relatively set grinding rollers 202 are tightly pressed against the side surfaces of the graphite electrode column 4, and then the conveying control screw 102 is controlled by the conveying control motor 109 to rotate forward, so that the external air enters the gear air supply box 105 after passing through the dust filter screen 112, and the air inside the gear air supply box 105 is The air passes through the air inlet pipe 113 and flows into the column polishing box 103. The airflow entering the column polishing box 103 carries the graphite powder generated during the polishing process through the air outlet pipe 114 and enters the dust filter box 107. The graphite powder in the airflow is absorbed by the dust filter water in the dust filter box 107, thereby achieving water absorption and filtration of the graphite powder during the polishing process. The treated airflow goes upward along the air guide pipe 121 into the push flow water tank 119. As the air pressure in the push flow water tank 119 gradually increases, the push flow piston disk 124 is pushed to move upward and disengage from the limit ring 123. In this process, the push flow piston disk 124 is used to push the push flow The water in the water tank 119 is pushed into the cooling guide box 129 along the water guide pipe 130.

At this time, the controller receives the pressure signal from the second pressure sensor and controls the delivery control motor 109 to restart, and at the same time controls the control solenoid valve 132 to open. 32 is closed, and the push flow water tank 119 is automatically filled through the automatic water supply pipe 122. In this way, the circulation control can realize the powder collection and cooling treatment during the grinding process of the graphite electrode column 4. The water entering the cooling guide box 129 enters the water inlet pipe 203 under the action of gravity, and then flows into the cooling cavity on the grinding roller 202 through the water inlet pipe 203, and finally is discharged from the water outlet pipe 204 to realize the collection of cooling water. The continuous flow of water in the cooling cavity can realize the continuous cooling of the grinding roller 202. Combined with the wind cooling effect generated by the air flow, the cooling effect of the graphite electrode column 4 and the grinding roller 202 during the grinding process can be greatly improved;

[0044] After the grinding process of the graphite electrode column 4 is completed, the controller controls the pushing electromagnet on the top of the horizontal magnetic seat 101 to be energized and magnetized, and the vertical guide seat 301 is moved upward and close to the threaded structure on the conveying control screw 102 under the action of the strong magnetic repulsion force, and then the conveying control screw 102 is controlled by the conveying control motor 109 to rotate in the opposite direction, so that the vertical guide seat 301 moves upward along the conveying control screw 102 until the entire electrode column positioning mechanism 3 is lifted to the initial position (i.e., above the column grinding box 103), and at this time, the pushing electromagnet on the top of the horizontal magnetic seat 101 is controlled to be powered off and demagnetized, and after the graphite electrode column 4 is disassembled, a graphite electrode column 4 to be ground is clamped and fixed again, and the grinding process of a graphite electrode column 4 can be realized again according to the same grinding control method as mentioned above.
