Abstract
The invention relates to a device and method for cleaning away a wet and sticky come-out object through thermal airflow. The device comprises an engine system, a cross-flow fan assembly and a vibrating screen. When the cleaning operation is carried out, thermal airflow generated by an engine flows through a guide pipe into a cross-flow fan and then enters a cleaning chamber through a streamline arc plate on the lower portion of the vibrating screen, and due to the adjustability of the streamline arc plate and the sliding performance of a lower vibrating plate, different materials can be cleaned by adjusting the positions of the streamline arc plate and the lower vibrating plate. By means of the technical scheme, the thermal air flow dries the come-out object, and the cleaning function on the wet and sticky come-out object is improved; the adjustable streamline arc plate is adopted, the airflow blocking on the fan is reduced through the high speed airflow produced through the streamline arc plate in the arc direction, and the front screen airflow speed and the cleaning efficiency are improved. According to the device and method, the energy sources of the engine can be repeatedly utilized, and can efficiently clean the wet and sticky materials.
