Anode slotting method

Abstract

The invention provides an anode slotting method. The anode slotting method comprises the following steps of 1 using an input roller way to convey a calcinated anode carbon block to a slotting position of a slotting machine, 2 using an amplitude-limiting filtering method to eliminate an interference signal, 3 pressing down and fixing the calcinated anode carbon block by means of a pressing device of the slotting machine, 4 using a frequency converter to adjust the rotation speed of a cutter motor from 1200-1300 turns / minute to 900-1000 turns / minutes, 5 using a lifting motor to lift a cutter rest and slotting the bottom of the calcinated anode carbon block, 6 using the input roller way to convey the slotted calcinated anode carbon block to a carbon block shunting position of the input roller way after slotting, 7 adding a connecting roller way connected with the input roller way and an output roller way at the carbon block shunting position and arranging an air cylinder on the connecting roller way. Compared with the relevant arts, the anode slotting method has the advantages that the slotted anode carbon block is better in quality, higher in slotting efficiency and better in working environment.

Description

【Technical field】 [0001] The invention relates to the technical field of anodes, in particular to an anode slotting method. 【Background technique】 [0002] The slotting of the anode is beneficial to prevent the anode from cracking, and the air bubbles are discharged from the bottom of the anode, which improves the stability of the electrolytic cell and helps to reduce the pressure drop of the electrolytic cell. [0003] In the anode slotting method of the related art, the anode carbon block after roasting, the input roller table, the output roller table connected in parallel with the input roller table and the slotting machine are provided, and the slotting machine includes a frame, a lifting frame fixed on the frame The motor and the pressing device, the tool holder and the connecting rods fixed on the two ends of the top of the tool holder respectively. The lifting motor controls the rising and falling of the tool holder through the two connecting rods. There are several b...

AI Technical Summary

Problems solved by technology

Due to the uneven bottom of the roasted anode carbon block, it is easy to shake when it reaches the slotting position, resulting in multiple cutting signals, which easily leads to multiple slots; the cutter motor rotates too fast and cannot be adjusted, resulting in loud noise and dust ;The speed of conveying the slotted anode carbon block from the input roller table to the output roller table is slow, which is easy to cause blockage on the roller table and affect the slotting efficiency

Therefore, the anode slotting method of the related art has the disadvantages of poor quality of the anode carbon block after slotting, low slotting efficiency, and poor working environment
