Rotary dryer, also known as the drum dryer. Is the most common drying equipment for application. It has the advantages of simple structure, balanced operation, convenient operation, reliable use of materials, strong applicability, occupy less labor, long service life of the equipment. For industrial production processes in a variety of drying dehydration.
1, the cylinder. It is composed of steel plate welded circular cylinder. At the feed end is welded with a stopper ring and spiral plate. In the middle cylinder is welded with a lifting plate, the discharge end is welded with the formation of material blocking ring ring lining material. The cylinder body and the level was 5%. The horizontal installation, wet the material into the cylinder by a high-end, into the feed section of the spiral section. Process of wet material along the cylinder axial movement, on the one hand by the cylinder heat transfer, on the one hand it is a process of lifter raise waterfall falling and hot air heat exchange. The wet material moisture is evaporated in the heating process. Gradually reduce the moisture, which is drying process. The dried material discharged from the cylinder end.
2, support device. The tyre set on a cylinder body with the cylinder together with the rotary supporting wheel. Wheel is mounted on the frame. In order to limit the axial movement of the cylinder gear wheel, is arranged on the machine frame, gear wheel and tyre 5mm inclined inclined cylinder clearance. In the axial runout controlled within 5mm, in order to work in the cooling roller, water filled in the bracket groove. The cooling water is the cooling of the roller and tyre, but also has the role of lubrication.
3, transmission device. The big gear and the cylinder sleeve in the cylinder body is fixedly connected with the gear driven by the motor through the belt. The small gear, reducer, small gear, gear drive cylinder for rotary motion.
4, ancillary equipment. For drying production, ancillary equipment drying machine configuration to adapt. The wet material enters the drying machine by the end, the general should be equipped with feeding conveyor. In order to final moisture stable drying products, the general should be configured feeding machine control suction amount. The material should be dried out into the chute, the hot material to the right place, the general should be equipped with vibrating conveyor or belt conveyor. The heat of modern industrial production and civilized production are required to meet the requirements of environmental protection. Dryer heat is burning hot blast furnace, hot blast furnace coal should be blower, exhaust emissions due to fan and dust. Due to the different fuel. A variety of ancillary equipment, ancillary equipment by the use of units according to various conditions to choose a variety of programs. The dryer factory supply only part of the host, which comprises a cylinder part, a full set of supporting device, transmission Pneumatic device.
1, drying machine installed shall be not less than 4 hours of empty machine commissioning, commissioning work in abnormal situation should be promptly treated.
2, after commissioning again tighten all bolts, check and replenish lubricating oil, try moving to normal after the load test.
3, load test machine with various ancillary equipment before commissioning. Single empty single commissioning after success into joint commissioning.
4, ignite the hot-air drying machine preheating, and the driving of the rotary dryer, prohibit the cylinder does not turn heating, to prevent tube bending.
5, according to the situation gradually adding wet material preheating, to the drying cylinder, according to the situation of water discharge, increase the volume of feed gradually. The need for a process of preheating drying machine, hot blast furnace should be a preheating process, no sudden fire fierce burn. To prevent local overheating, uneven thermal expansion and damage.
6, fuel level, the quality of insulation quality, how much water wet material, the degree of uniformity of feeding quantity, affect the quality of drying products, affect fuel consumption. So each part of the best is the effective way to improve economic efficiency as much as possible.
7, in the working state, the roller frame should be filled with cooling water. The lubricating parts should be timely refueling.
8, parking should put hot stove flameout, drying cylinder should continue to rotate until the cooling to the parking lot to close to the outside temperature. When the temperature is prohibited parking, prevent the bending deformation of the cylinder.
9, encountered a sudden power failure, should immediately put the stove flameout, stop feeding, every 15 minutes drive cylinder half turn, until the cylinder cooling so far. The operation rules should be specifically responsible, in violation of this regulation will result in tube bending. The cylinder will cause serious bending can not properly use the dryer.
