A Video System for Real-time Monitoring of Mill Filling Rate

Abstract

The invention belongs to the field of mining equipment, and in particular relates to a video system for monitoring the filling rate of a mill in real time. The device is fixed on the back of the upper part of the material chute through a connecting piece. The end of the protection device facing the mill is provided with a glass window for the passage of long waves. The camera adopts a long-wave radiation industrial camera. The camera is set in the protection device. The video information inside the mill is collected, and the collected video information is sent to a remote computer through a cable using a network communication protocol. The flushing device includes a compressed air pipeline and a clean water pipeline, and the compressed air pipeline and the clean water pipeline are respectively set in the protection On the device, it is used to clean the glass window, and the filling rate data inside the mill can be collected online in real time without stopping the machine, so as to ensure the normal production of the mill.

Description

technical field [0001] The invention belongs to the field of mining equipment, and in particular relates to a video system for real-time monitoring of the filling rate of a mill. Background technique [0002] As an important equipment of mining enterprises, mill is mainly used in the crushing and grinding section of ore. The ore enters the mill from the chute at the feed end of the mill. The inside of the mill is a closed space, rich in dust and water vapor, and the working conditions are harsh, which makes it difficult to observe the internal conditions of the mill, and the filling rate inside the mill cannot be timely Feedback to the central control personnel, if the operation is improper, it is easy to cause the mill to bulge, the under-load to smash the liner and so on. Expansion of the belly will lead to shutdown, and the inside of the mill must be treated before re-production; empty smashing of the liner will aggravate the wear of the liner, and even cause the liner t...

Problems solved by technology

The ore enters the mill from the chute at the feed end of the mill. The inside of the mill is a closed space, rich in dust and water vapor, and the working conditions are harsh, which makes it difficult to observe the internal conditions of the mill, and the filling rate inside the mill cannot be timely Feedback to the central control personnel, if the operation is improper, it is easy to cause the phenomenon of mill belly swelling, under-load empty lining board, etc.

Expansion of the belly will lead to shutdown, and the inside of the mill must be treated before re-production; empty smashing of the liner will aggravate the wear of the liner, and even cause the liner to break, which seriously affects the normal production of the mining enterprise and brings great harm to the mining enterprise. cause economic loss
