Drum dryer, drum dryer, graphite drum dryer, second-hand drum dryer, sawdust dryer refers to the continuous addition of wet sawdust in the form of powder particles into a drying tube using a screw conveyor. In the transportation and dispersion of high-speed hot air flow, the process of evaporating the moisture in wet materials to obtain powdered or granular dried products. Mainly composed of air heater, feeder, airflow drying tube, and cyclone separator
Composed of fans and other components. Characteristics of sawdust dryer: 1. High drying intensity due to the highly dispersed material in the airflow.Idle disposal of second-hand organic fertilizer dryer
The rotating drum, filter drum, material conveying pipe, cooling drum, and discharge port are located on the active roller,
The active roller is driven by a motor and a reduction drive to rotate the rotating drum at low speed. There is a feeding port between the heating furnace and the rotating drum,
There are stir frying blades inside the rotating drum, and a baffle is installed at the connection between the rotating drum and the filter drum 4. There is a small hole on the baffle,
One end of the filter cylinder is connected to the rotating cylinder, and the other end is connected to the material conveying pipe. There is a stopper inside the filter cylinder,
The bottom of the filter cylinder is equipped with a slag discharge hole, and one end of the cooling cylinder is connected to the material conveying pipe through a blower,
The other end is connected to the discharge port. Due to the use of the above structure, sawdust can be fully dried inside the rotating drum,
And the sawdust is fully dispersed again before entering the material conveying pipe, so that the water evaporates quickly. The stopper can block the impurities in the sawdust,
Ensure the quality of sawdust entering the material conveying pipe. The sawdust enters the sawdust dryer through the joint action of the spray pipe and the rotary cylinder,
The material boils and fluidized inside the cylinder, and the hot air fully contacts the material, completing the drying process. Scope of application of sawdust dryer: Airflow sawdust dryer is widely used for straw pellet fuel
Industries such as charcoal machinery, wood pellet fuel, sawdust compaction, and agricultural and animal husbandry engineering. Such as corn stover drying, soybean stover drying, cotton stover drying
Drying of agricultural cellulose materials such as wheat straw, sorghum straw, sawdust, shavings, sawdust, ginkgo leaves, and mulberry leaves.
Drying equipment is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry powder mortar industry and various specifications of molding sand used in the casting industry. Blast furnace slag used in the building materials and cement industry. Small particle clay is used in the chemical industry for small particle materials that do not undergo chemical changes, are not afraid of high temperatures, and are not contaminated by smoke and dust. According to the moisture requirements of different industries for dried materials, the moisture content of dried materials can reach below 1-5%.
The materials entering the dryer should not stick to the cylinder wall or the poplar board. The temperature of the gas entering the dryer for heat exchange should not exceed 750 degrees Celsius. If there are special requirements for high-temperature drying, the inner cylinder and poplar board at the inlet of the dryer can be made of heat-resistant steel plates.
Installation and maintenance/Idle disposal of second-hand organic fertilizer dryer
The maintenance and upkeep of machines is an extremely important and regular task, which should be closely coordinated with the operation and maintenance. There should be dedicated personnel on duty to conduct inspections
