According to the characteristics of wood chips, sawdust and wood materials, the dryer has been comprehensively technically modified on how to improve the filling rate of materials and the residence time of materials in the cylinder. A new type of combined lifting device and multi-layer multi drum structure have been adopted to make the material without wind tunnel, so that the wood chips can fully exchange heat and dehydrate, and the coarse and fine particles separation device is added, the heat utilization rate is and output greatly improved. Under the same investment conditions, the advantages of the dryer of GuoXin produced very obvious.
The sawdust enters the belt conveyor through the feeding hopper, and the equal-thickness stream is fed into the dryer feeding port through the feeding air-closing device, and enters the multi-cylinder roller together with the high-temperature hot flue gas from the hot air furnace at the feeding port of the dryer. after three cycles of mass heat exchange to complete the drying of the material, the dried material enters the multi-group cyclone separator, the dry material is discharged through the discharge air shut-off device, and a part enters the briquetting system and is extruded into blocks. Forming the finished product. Another part of the material enters the anti-blocking fuel feeding device, and is sent to the hot blast stove through the fuel feeding fan, and under the action of the cyclone-enhanced combustion fan, the combustion is completed and the high-temperature flue gas is formed, which is used as the whole drying system. The exhaust from the cyclone is discharged into the atmosphere.
Features of multi-drum sawdust dryer:
1, The drying system uses a part of the product produced by itself as fuel, without additional fuel. It is only necessary to continuously add the dried wet wood chips to the system to produce continuous dry wood chips.
2, The drying system is equipped with a special wood chip cyclone burner and automatic returning system, no need for on-site masonry, easy to install, the furnace is equipped with over-temperature alarm, flame monitoring, tempering alarm, fuel isolation device to ensure combustion safety.
3, The drying system is equipped with a three-ring tumble dryer and uses a high-temperature rapid drying process to increase the drying strength. Increased thermal efficiency, reduced installed capacity and floor space, and guaranteed product quality.
4, The drying system adopts the fuzzy control principle, equipped with online moisture detection and automatic water control, which not only ensures the product quality, but also greatly reduces the labor intensity of workers.
5, The drying system uses a unique method to minimize the possibility of internal combustion explosion, and is equipped with automatic fire prevention and explosion-proof devices to ensure safe production.
