Dryer operation and maintenance and troubleshooting

1. The drying efficiency of the dryer depends largely on the quality of the combustion chamber. Therefore, special attention must be paid to the combustion chamber, the blower and the dust collection and cleaning equipment during the operation of the dryer.

2. Ignit the stove one hour before starting the dryer. Check that all accessory equipment, including the various transmission parts of the dryer, the dragging part, etc., should be fastened, normal, slippery, and reliable to drive.

(a) Before the furnace is ignited, the furnace, hearth, feeding device, combustion chamber, furnace slag, furnace door, air duct, regulating valve, blower, and dust remover shall be inspected.

(2) Before starting the dryer, check the lubrication of all bearings and friction surfaces of the fuel, tools, and drive support devices.

(3) The step of starting the dryer is to start the dryer motor first, then start the transport of the wet material equipment, and then start the dry material conveying equipment to form a continuous and uniform operation program.

3, during the operation of the dryer should always check the temperature of each part of the bearing, the temperature must not exceed 50 °C, the gear sound response is stable, the transmission, support and cylinder rotation should be no obvious impact, vibration and transmission, but also often Do a good job in the inspection, maintenance, and maintenance of equipment. The contents should include:

(1) All bolted fasteners should not be loosened.

(b) Always pay attention to the contact between the roller ring, stop wheel and tugboat.

(C) windshield ring, gear cover should not have wing cracks and friction damage.

(d) All parts should be properly lubricated in the following table. Lubrication points: Lubrication material lubrication time and cycle motor sodium-calcium fat 6 months; reducer bearings calcium grease 6 months; reducer gear 10 # oil change / 3 months; transmission bearing calcium grease 2 times / class; Support bearing sodium calcium grease for 6 months; retainer bearing sodium and calcium grease for 6 months

Dryer failure and elimination:

1, the moisture content of the material after drying is greater than the specified value, the elimination method is to control the production capacity of the dryer, increase or reduce the supply of heat;

2. The roller oscillates on the operation of the cylinder. The reason is that the side of the concave joint of the roller is not clamped. The elimination method is to use a backing plate to keep the roller ring and female connector evenly and clamp properly to prevent over-tightening. have an accident;

3. The meshing gap between the large gear and the small gear is destroyed because a. The tug wear b. The stop wheel wear c. The pinion wear The elimination method is to turn or replace according to the wear condition, or it can be installed or updated in reverse. ;

4, the whole body vibration, the reason is a. The connection between the tug device and the base is destroyed, and the elimination method is to correct the fastening connection position so that it is in the correct position;

5, the side of the roller wear, the elimination method is based on the degree of wear thoroughly, turning or replacement of the roller.
