Latest device for online monitoring of coal quality components of coals as received

Abstract

The invention discloses a latest device for online monitoring of coal quality components of coals as received, namely a detecting device for unprocessed raw coal components. The device comprises a belt for conveying coals, and a coal component detecting device and a foreign matter controller arranged on the belt, wherein the foreign matter controller is used for detecting heights of ultrahigh foreign matters on the belt before the coals enter a detecting range of the coal component detecting device; the coal component detecting device is used for detecting components of the coals on the belt;and the coal component detecting device comprises a detecting head and a light guide cylinder arranged under the detecting head. The latest device solves the technical problem of easy destruction of the coal component detecting device in the coal detecting process in the prior art.

Description

technical field [0001] The invention relates to the field of coal detection equipment, in particular to an up-to-date device for on-line monitoring of coal quality components of incoming coal. Background technique [0002] It has been observed that before the coal is unloaded into the belt and tested for coal composition, it will pass through a 400x400mm rigid metal square hole frame for filtration. The large foreign matter that can pass through the square hole frame can only be a columnar foreign body with an outer diameter of about 400mm and an extra long length. , if this super-long foreign object travels on a high-speed (3m / s) coal conveyor belt, it will have high kinetic energy, and it will cause serious damage to the equipment when it hits the coal composition detection device. This has happened in history. The accident in which a long strip of foreign matter knocked down the portal frame of the coal conveyor belt. [0003] Aiming at the above-mentioned problem in the...
