Installation and commissioning of decolorization tower

1. Lift the decolorizing tower into the reserved hole on the floor, and insert the bolt holes of the upper lug support on the tower body into the reserved anchor bolts on the floor. Align the center verticality of the stirring shaft with a hammer line, and the upper and lower bearings of the stirring shaft must be on the same vertical line.

2. There should be no friction between the stirring blade and the tower body.

3. Before commissioning, clean up the sundries inside and outside the tower, check the bolt fastening and lubrication, and pay attention to the lubrication of transmission parts such as reducer and bearing.

4. Before feeding, it must run idling for 30 minutes according to the items of no-load operation, and check the operation again for any abnormal sound.

5. After the dry operation is normal, start feeding again.

Main points of decolorization tower operation:

1. Before feeding, it must run idling for 30 minutes according to the items of no-load operation, and check the operation again for any abnormal sound.

2. After the dry run is normal, start feeding again.

3. When the decolorization tower uses steam to stir, turn on the steam to preheat before entering the mixed oil.

4. When the white clay is mixed in, the condensed water in the stirring steam should be removed first, and then the stirring steam should be supplied to the decolorization tower. When the oil level reaches about half, turn on the decolorization pump to pump the oil from the decolorization tower to the filter for filtration.

Equipment care and maintenance:

1. Add lubricating grease on time to keep the bearings, reducer, gears, rollers and other parts well lubricated.

2. If abnormalities are found during operation, the machine should be shut down for maintenance immediately, and it is not allowed to run with a disease.

3. Always pay attention to the operation of the transmission part, whether there is abnormal noise, whether the temperature rise of the reducer and motor is normal, and whether the lubrication is good.

4. In the event of an accident, the cause should be found out in time and the fault should be eliminated.

5. The equipment should be combined with the actual situation of the workshop (factory), and the necessary maintenance system should be established.

Common faults and troubleshooting:

Common malfunctions	Failure cause	Method of exclusion
Depigmentation oil is too dark	White clay quantitative device	Check the clay quantitative device to see whether the clay tube is blocked and whether the quantitative device is opened flexibly and in place.
	The ratio of white clay added is too small	Whether there is any bridging of the white clay in the white clay temporary storage tank, and deal with it in time.
	Unsuitable temperature for decolorization	Adjust the decolorization oil inlet temperature.
	Check clay quality	If the quality of clay is too poor, just replace it.
Significant drop in vacuum	Leakage in the vacuum system, drop in vapor pressure to the jet pump	Jet pump nozzle clogged or other problems with the pump itself.
		The water content of the oil or clay is too high, causing the jet pump to overload.
		The cooling water entering the vacuum condenser is insufficient or the temperature is too high.

Common malfunctions	Failure cause	Method of exclusion
Abnormal sound in the tower	1. The stirrer is loose or broken; 2. The copper sleeve is severely worn and swings greatly;	1. Repair or replace; 2. Replacement;
The vibration of the whole machine is large	1. The vibration of the reducer exceeds the standard; 2. The fastening screw of the reducer is loose	1. Overhaul 2. Replacement
Stirring does not turn	1. The motor burns out or loses phase; 2. The reducer is damaged;	1. Repair or replace 2. Replacement
