Abstract

The invention discloses a powder coal screening device. The powder coal screening device comprises a frame. The upper end of the frame is provided with an air pipe for delivering coal. The upper end of the frame is provided with a screen. The coal in the air pipe falls onto the screen. A collection tank is arranged under the screen. The left and right ends of the screen are both provided with air cylinders. Guide rods of the air cylinders are connected with the two ends of the screen. The screen is driven by the air cylinders to do reciprocating movement. According to the powder coal screen device, the air cylinders are arranged to drive the screen to do reciprocating movement so as to achieve the screening effect. Small coal falls into the collection tank. Big coal is left on the screen and is pushed by a push plate to go into a recycling tank. The powder coal screening device is simple in structure, convenient to operate and low in screening cost, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a powder coal screening device. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground through complex biochemical and physicochemical changes. It is a kind of solid combustible organic rock, which is mainly formed by biochemical action of plant remains, and then transformed by geological action after burial, commonly known as coal. Coal is hailed as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. Since the beginning of the 21st century, although the value of coal has dropped significantly, after all, the present and the future are very long. For a period of time, coal is still one of the indispensable energy sources for our human production and life. The supply of coal is also related to the stability of the development...
