Description

Technical Field

[0001] The utility model relates to the field of coal mills, in particular to an acoustic monitor for coal mill fault monitoring. Background Art

[0002] Coal mill is a machine that breaks coal blocks and grinds them into coal powder. It is an important auxiliary equipment for pulverized coal furnaces. There are vertical mills, high-pressure suspension roller mills, medium-speed micro-powder mills, overpressure trapezoidal mills, Raymond mills and other models.

[0003] The coal grinding process is the process of coal being broken and its surface area increasing continuously. To increase the new surface area, the binding force between solid molecules must be overcome, which requires energy consumption. Coal is ground into coal powder in the coal mill, mainly through three methods: crushing, crushing and grinding. Among them, the crushing process consumes the least energy, and the grinding process consumes the most energy. Various coal mills have two or three of the above methods in the powder making process, but which one is the main one depends on the type of coal mill.

[0004] When the current coal mill grinds coal blocks for a long time, abnormal noises are prone to occur inside the device. When the device has abnormal noise failures, it needs to use an acoustic monitor for auxiliary operation. However, the current acoustic monitor consists of a monitor, a monitoring head and headphones with a connecting line. However, when using the current acoustic monitor, personnel need to manually take the monitor for operation. When detecting special positions of the coal mill, it is inconvenient for the staff to manually take the monitor for monitoring. At the same time, the coal mill needs to perform fault acoustic monitoring during operation, which increases the risk of operation during monitoring.

[0005] Therefore, it is necessary to provide an acoustic monitor for coal mill fault monitoring to solve the above technical problems. Utility Model Content
