Fixed blade of residue anode pressure-disengaging machine

[0002] At present, the single anode automatic residual pressure off-line used in the domestic aluminum industry is basically similar. It is mainly composed of the upper fixed knife group, the lower movable knife group and the clamping mechanism. After long-term tracking of the use of this type of equipment, the following deficiencies are found : 1. The positioning and clamping mechanism is easy to break from the root, and the body is deformed and cracked; 2. The blade wears quickly and is fragile, and the blade fastening screw is easy to break and is difficult to remove. It is inconvenient to maintain and replace the blade; The connecting screw is deformed by the residual carbon block for a long time, it is difficult to disassemble, and the connecting bolt of the movable blade is easy to break; 4. The two pressure release cylinders are not synchronized, the movable knife holder of the lower knife group is skewed, and the guide mechanism of the knife holder wears quickly and is not easy to replace; 5. 1. The failure rate of the hydraulic system is high, especially the spool of the flow diversion valve is easy to break, and debris often enters the hydraulic pipeline system and often damages the fluid; 6. The pressure system is difficult to troubleshoot, the inspection and repair period is long, and the maintenance cost is high. Valves have the same problem
