Grinding ball sensor used for monitoring internal medium motion status of ball milling machine

Abstract

The invention relates to a grinding ball sensor used for monitoring internal medium motion status of a ball milling machine. The grinding ball sensor includes an inertial sensor circuit board, a spherical bearing body, a battery and a wireless charging receiver. The inertial sensor circuit board, the battery and the wireless charging receiver are arranged in the spherical bearing body. The battery is used for supplying power to the inertial sensor circuit board. The inertial sensor circuit board includes a six-shaft inertial sensor, a temperature sensor, a wireless transmission module, an embedded CPU, a flash memory and a power supply management module, wherein the six-shaft inertial sensor and the temperature sensor send the acquired data to the embedded CPU respectively. The embedded CPU stores the received data in the flash memory. After data acquisition is finished, the embedded CPU reads the content of the flash memory and sends the read content to a host computer through the wireless transmission module in a wireless transmitting manner. The wireless charging receiver charges the battery in a wireless manner. The spherical bearing body comprises a ball cover and a ball base.

Description

technical field [0001] The invention relates to the technical field of inertial sensors, in particular to a ball sensor for monitoring the movement state of a medium inside a ball mill. Background technique [0002] Ball mill is a kind of traditional grinding equipment, which realizes the crushing of materials by the impact and grinding of media (grinding balls) on materials. When the cylinder rotates around the central axis, the grinding balls and materials rise to a certain height with the cylinder wall under the action of centrifugal force and friction force, and then fall away to roll or throw. Compared with other grinding equipment, the ball mill has the advantages of wide material adaptability, simple operation and maintenance, and high reliability, but it also has the disadvantages of low work efficiency and high power consumption. Therefore, how to improve the grinding production efficiency and reduce power consumption is very important. At present, due to the lack...

Problems solved by technology

However, due to the dim light inside the ball mill, especially in the wet grinding method, the medium, grinding body and camera lens are easily polluted by water vapor, dust, mud, etc., making it difficult to observe; However, in practical applications, since the cylinder of the ball mill is generally made of metal materials, the magnetoresistive sensor cannot work in a metal container.

In addition, this method is difficult to read data of multiple spheres at the same time, so the current method of monitoring the internal medium of the ball mill is insufficient
