An external ball mill intelligent monitoring and control system

Abstract

The present invention relates to an intelligent monitoring control system of an external connection type ball mill. The system comprises a temperature acquisition module, a signal transmission module used for transmitting a temperature signal acquired by the temperature acquisition module, and a data intelligent analysis and control module. The signal transmission module is used for transmitting data measured by the temperature acquisition module to the intelligent analysis module. The intelligent analysis module is used for analyzing a data document, and sending out an early-warning signal or sending an instruction to a control part thereof. The control system is independent of an original electrical system, and is high in adaptability. High-performance thermoelectric materials are adopted to prepare a temperature sensor, so that the temperature acquisition accuracy can be improved. In addition, the system realizes the data intelligent analysis and the instruction control of the control module, and is operated in the programming manner instead of the single software. Therefore, the system is strong in compatibility, and convenient in personalized setting.

Description

Technical field [0001] The invention relates to an intelligent monitoring and control system for an external ball mill, belonging to the field of mechanical intelligent monitoring and control. Background technique [0002] For a long time, the degree of automation of mineral processing machinery is generally low, resulting in high mechanical failure rate and low production efficiency. The normal operation of machinery in this field is based on its driving devices and stress components. Knowing the main failure performance and causes of these components, and achieving reasonable monitoring and early warning can greatly improve production efficiency. As the most commonly used processing machine, it is of great significance to carry out technical research and early warning system development for dry ball mills. [0003] The main body of the dry ball mill consists of three parts: a hollow shaft, a bearing bush and a cylinder. The operation of the ball mill system is mainly output by ...

Problems solved by technology

[0004] At present, the domestic data monitoring system for ball mill temperature is relatively mature. The monitoring function is realized by using traditional temperature sensors and integrating existing software. Although this method is mature, it requires too many supporting systems, such as signal amplifiers and filters. etc., it is necessary to cooperate with complex wiring and compensation circuits to reduce signal interference, which not only cannot fundamentally solve the problem of signal interference in the long-distance signal transmission process, but also relies too much on the relay amplification or enhancement of the initial signal, making the structure complex and the signal The error is large, and the installation threshold is high, which requires a large degree of mechanical modification, which is not suitable for the modification of old mineral processing production lines

In terms of control, as a large-scale mineral processing machine, the control system of the ball mill is generally composed of electrical control systems of multiple components. It is usually started by frequency conversion and needs to be placed in the power distribution room to be operated by the power distributor. Therefore, direct automatic control is possible. It will cause mechanical damage, making this aspect overly dependent on manpower, and the initial mechanical failure performance cannot be observed intuitively, making it difficult to detect and prevent the occurrence of mechanical failure in time
