Embodiment Construction

[0017] Such as figure 1 As shown, a ball mill material level detection device of the present invention includes a material level detection sensor, and also includes a mutual induction module 1, a rectification module 2, a voltage stabilizing module 3 and a battery 4, and the output terminal of the mutual induction module 1 is connected with the rectification module 2, and the rectification module The module 2 is connected to the voltage stabilizing module 3, and the voltage stabilizing module 3 is connected to the storage battery 4;

[0018] The material level detection sensor uses a vibration sensor and an acceleration sensor. The material level detection sensor is connected to the preamplifier to amplify and filter the signal to improve the signal-to-noise ratio of the signal and make the signal amplitude meet the range of analog-to-digital conversion. Finally The final digital signal is obtained through analog-to-digital conversion processing.

[0019] The mutual inductanc...

Abstract

The invention relates to a material level detection device for a ball grinding mill, pertaining to the technical field of detection equipment. The invention is intended for providing the material level detection device for the ball grinding mill which resolves defects of a power supply battery of a conventional material level detection device for a ball grinding mill such as large battery size, limited service lifetime as well as the great difficulty in regular maintenance and replacement. The technical scheme with the aim of resolving the technical problem is described in that a mutual inductance module arranged on the ball grinding mill generates mutual inductance current and a storage battery is used for storing electric energy so that power supply is achieved. The material level detection device is extensively applied to the field of ball grinding mills.

Description

technical field [0001] The invention relates to a ball mill material level detection device, which belongs to the technical field of ball mill detection equipment. Background technique [0002] With the rapid development of MEMS, SoC and wireless communication technology, wireless sensor network technology has become a research hotspot at home and abroad. However, the vast majority of material level detection devices based on wireless sensor nodes use chemical energy batteries for power supply, while traditional chemical energy batteries have disadvantages such as limited energy, need to be replaced regularly, and pollute the environment, which is not conducive to giving full play to the maximum role of wireless sensors. [0003] Roller ball mill is a typical milling equipment, mainly used in electric power, mining, cement and chemical industries. Material level detection is one of the most important means to obtain ball mill parameters. Real-time and continuous ball mill m...
