TECHNICAL FIELD
[0001] The utility model belongs to carbon black drying processing device technical field, concretely relates to a carbon black airflow drying device. BACKGROUND
[0002] Carbon black is mainly formed by hydrocarbon compounds under high temperature, and the main component is carbon, and contains a small amount of hydrogen, oxygen and sulfur and other elements, and is widely used in many fields. In the production, storage and transportation process of carbon black, due to equipment failure or improper process control, carbon black is stored for a long time, and due to the moisture absorption of carbon black itself or the reason of being drenched, etc. The moisture content of carbon black products is exceeded, which causes carbon black caking, etc. These will affect the use performance and product quality of carbon black products, cause customers to refuse carbon black products or complain about quality problems, therefore, the carbon black with excessive moisture must be dried. The existence of excessive moisture of carbon black will affect the performance and quality of carbon black, so drying is needed. A commonly used drying method is the cyclone airflow drying method, which generally uses a cyclone airflow drying device. The cyclone airflow drying device is mainly composed of an air heater, a drying pipe, a cyclone separator, a spiral feeder, a bag filter and a fan and other equipment. Its principle is that hot air enters the cyclone dryer tangentially to form a rotating airflow. Carbon black material is added from the top of the dryer and spirally descends along the wall under the action of the rotating airflow, and is fully contacted with hot air for drying. The dried carbon black is discharged from the bottom, and the tail gas is separated by the cyclone separator and discharged. Through airflow drying, the moisture in the carbon black is evaporated and carried away, which is convenient for the storage and transportation of carbon black material products, maintains the good dispersibility of carbon black, and avoids the agglomeration and caking of carbon black material;
[0003] When the cyclone airflow drying device is used for drying carbon black wet material, the spiral feeder is used for feeding. When feeding, due to the certain humidity of the material, caking is formed on the inner wall of the drying pipe and the pipeline, which causes blockage. The wet material conveyed by the spiral feeder cannot be pre-screened, dispersed and pre-dried, which has defects.
[0004] The existing cyclone airflow drying device has the problem of not pre-treating the wet material conveyed by the spiral feeder for pre-screening, dispersion and pre-drying when used for drying carbon black wet material.
