Pulverized coal sorting device

Abstract

The invention discloses a pulverized coal sorting device. A driving assembly drives a knocking assembly to get close to a filter screen, so that horizontal reciprocating motion of the knocking assembly in the X direction is achieved, and preparation is made for the knocking assembly to knock and vibrate the filter screen. A driving motor drives a second gear to be meshed with a first gear, a rotating shaft rotates, a transition shaft and a driving gear move along with the rotating shaft, the driving gear is meshed with a fixed gear, and the driving gear rotates while rotating around the central axis of the rotating shaft, so that a driving plate is driven to reciprocate in the X direction, and the driving plate is always perpendicular to the X direction in the moving process. The knocking assembly pushes a first translation plate to move in the Y direction through an electric push rod, and a rack A and a rack B move along with the first translation plate. A gear A and a gear C are meshed with a gear A and a gear B correspondingly, a telescopic piece is folded or unfolded, and a knocking piece is folded or unfolded along with the telescopic piece. The knocking piece is close to the filter screen under the action of the driving assembly, and a knocking block knocks the filter screen.

Description

technical field [0001] The invention specifically relates to a pulverized coal separation device. Background technique [0002] Coal is the conventional energy source with the largest grain storage and the widest distribution in the world. Coal is a non-renewable resource. It is a solid combustible mineral that was gradually formed by ancient plants buried in the ground through complex biochemical and physical chemical changes. It is a solid combustible organic rock. Transformed by geological processes. [0003] Pulverized coal is one of the important products of coal processing, and pulverized coal separation is one of the important steps in pulverized coal processing. Pulverized coal separation is to bring the air from coal grinding into the separator through the lower air pipe, rectified by the inner cone and then decelerate and rise along the passage between the outer shell and the inner shell, and the coarse powder in it is settled by gravity. Sliding along the cone ...

Problems solved by technology

However, the fine powder discharge pipe of the existing powder classifier is very easy to block, and cannot be dredged automatically. It needs manual automatic dredging, which is time-consuming and laborious, and greatly reduces the powder selection efficiency of the powder classifier.
