The working principle of the invention is:
1, by control cabinet open the first valve of the first valve group being connected to first rinsing bowl, the second valve group first
Valve, motor drive water pump to start to work, and the water in rinsing bowl enters pipeline from the outflow of water outlet 13 with certain flow rate, by the
First valve of one valve group enters acid pickling tube 29, carries out circulation flushing, cleaning to acid pickling tube 29, water passes through the first of the second valve group
Valve returns, and returns to rinsing bowl by water inlet.After rinsing cleaning acid pickling tube, be connected to rinsing bowl the is closed by control cabinet
First valve of one valve group, opens simultaneously the intake valve of the first valve group, by being passed through compressed air hydraulic pressure return water in acid pickling tube
Washing trough is then shut off the second valve group intake valve being connected with rinsing bowl, opens simultaneously valve group blowdown valve and the exhaust of the second valve group
The water that can not be emptied completely is discharged into gutter by valve, closes the groove body blowdown valve of the second valve group, and compressed air passes through the second valve group
Exhaust valve discharge, moisture remaining in pipeline is blown off by compressed air, close the first valve group intake valve and the second valve
The exhaust valve of group.
2, the second valve of the first valve group being connected to rinsing bowl, the second valve of the second valve group are opened by control cabinet,
Motor drives water pump to start to work, and the acid solution in descaling bath enters pipeline from acid solution outlet outflow with certain flow rate, passes through first
Second valve of valve group enters acid pickling tube, carries out cycle pickling to acid pickling tube, and acid solution is returned by the second valve of the second valve group,
Descaling bath is returned by acid solution import.After cycle pickling acid pickling tube, the first valve group being connected to descaling bath is closed by control cabinet
The second valve, open simultaneously the intake valve of the first valve group, acid solution in acid pickling tube pushed back descaling bath by being passed through compressed air,
It is then shut off the second valve group intake valve being connected with descaling bath, opens simultaneously the valve group blowdown valve and exhaust valve of the second valve group,
The acid solution that can not be emptied completely is discharged into gutter, closes the groove body blowdown valve of the second valve group, and compressed air passes through the second valve group
Exhaust valve discharge, blows off acid solution remaining in pipeline by compressed air, closes the intake valve and the second valve group of the first valve group
Exhaust valve.
3, the second valve of the first valve group being connected to deactivation slot, the second valve of the second valve group are opened by control cabinet,
Motor drives water pump to start to work, and the passivating solution in deactivation slot enters pipeline from passivating solution outlet outflow with certain flow rate, passes through
Second valve of the first valve group enters acid pickling tube, carries out circulation passivation to acid pickling tube, passivating solution passes through the second valve of the second valve group
Door returns, and returns to deactivation slot by passivating solution import.After circulation passivation acid pickling tube, it is connected to by control cabinet closing with deactivation slot
Second valve of the first valve group, opens simultaneously the intake valve of the first valve group, by being passed through compressed air passivating solution in acid pickling tube
Deactivation slot is pushed back, the second valve group intake valve being connected with deactivation slot is then shut off, opens simultaneously the valve group blowdown valve of the second valve group
And exhaust valve, the passivating solution that can not be emptied completely is discharged into gutter, closes the groove body blowdown valve of the second valve group, compressed air is logical
Cross the second valve group exhaust valve discharge, passivating solution remaining in pipeline is blown off by compressed air, close the first valve group into
The exhaust valve of air valve and the second valve group.
4, acid pickling tube is rinsed by second rinsing bowl again, working principle is the same as first rinsing bowl.
5, water, acid solution, passivating solution guarantee the temperature and acid wash passivation effect of each tank liquor by being passed through steam heating.
6, the impurity inside each slot is periodically discharged by slot bottom blowdown valve.It is discharged when replacing tank liquor by slot bottom blowdown valve,
New liquid is filled from top.
