The first step compression: filter press machine to be carried out before the machine to check: to see whether the damage to the filter cloth, the power supply has been properly connected to the gas source pressure to 4 kg, after checking the compression operation, the first foot When the pressing force reaches the high point pressure of 42MPa, the pedal release hydraulic system automatically stops working, the cleaning of electrolytic products of the car placed in the filter Slice below.The second step feed: When the filter press, you can feed operation: open the feed valve, the liquid valve, open the feed pump, when the filter press feed pressure to 8-10 kg, The product to be filtered is cleaned. Filter press feed pump is equipped with electrical contact pressure gauge pressure gauge, when the feed pressure exceeds the maximum pressure (maximum pressure 12 kg), a sound and light alarm.The third step drainage air-dried discharge: When the filter feed pressure to 8-10 kg, shut down the feed pump and feed valve, close the outlet pipe on the right side of the valve. Open the compressed air intake valve, the filter inside the ventilation drainage, air-conditioning, ventilation time of about 40-60 minutes, drain the filter inside the electrolyte, listen to the liquid pipe without water flow, close the air compressed gas valve. Pedal pneumatic pump left pedal, piston rod driven compression plate back, retreated to the appropriate position, lift the hydraulic cylinder, this time filter can be separated, manually pull block by piece, with a plastic shovel to filter plate Electrolysis products, and then remove the filter plate with a high-pressure water gun clean. After cleaning, the filter plate in accordance with the original order and direction of installation to the filter, thus an operation cycle is completed.
