Turbine airflow grader

Abstract

The invention discloses a turbine airflow grader. The turbine airflow grader comprises a feeding opening and a grading device. The grading device is fixed into a support, and the upper end face of thegrading device is provided with a servo motor. One side of the grading device is connected with a dust treatment device in a sealed manner through a pipe, and the other side of the grading device isconnected with an induced draft fan in a sealed manner through a pipe. The feeding opening is connected with the induced draft fan in a sealed manner through a feeding pipe, and the induced draft fanis fixed to the upper end face of a base. The grading device is internally provided with a turbine, and the turbine is mounted on a rotating shaft, connected into the grading device, of the servo motor. The grading device is internally provided with a tipping bucket, and a lower end opening of the tipping bucket is connected with a fine particle storage chamber in a sealed manner through a fine particle outlet pipe. The lower end of the grading device is provided with a discharging opening. By means of the turbine airflow grader, coarse particles and fine particles can be separated precisely;a complete machine operates at the negative pressure, and no dust leaks; and the turbine airflow grader is provided with the dust treatment device, so that air pollution is reduced to be minimized.

Description

technical field [0001] The invention relates to the technical field of airflow classification, in particular to a turbine airflow classifier. Background technique [0002] Turbine airflow classifier is widely used in beneficiation plants to form a closed-circuit circulation with ball mills to separate ore sands, or to classify ore sand and fine mud in gravity beneficiation plants, and to classify ore pulp in metal beneficiation processes, and For desliming, dehydration and other operations in ore washing operations, the principle of the turbo air classifier is to use the wind force of the induced draft fan, and the air enters the volute from the air inlet. Due to the difference in the quality of the coarse and fine particles, the force is different, so that the coarse and fine particles Most of the separators currently used in the market are high in energy consumption, low in efficiency, bloated and difficult to maintain.
