Embodiment Construction

[0038] The present invention proposes a load detection method based on multi-sensor fusion for a drum ball mill, and its overall flow is as follows figure 2 As shown, it specifically includes the following steps:

[0039] 1) Install multiple sound sensors and vibration sensors in each section of the cylinder ball mill, and collect the noise and vibration information of each section of the cylinder ball mill at the same time, and obtain the noise and vibration data stream;

[0040] Among them, the sound sensor chooses a capacitive unidirectional microphone, and the response frequency is 20Hz-10kHz. For a single-chamber steel ball mill, install three sound sensors, which are respectively located at 1 / 4, 1 / 2, and 3 / 4 of the entrance of the cylinder; for a multi-chamber steel ball mill, the number of sound sensors installed is equal to the barrel The number of chambers of the steel ball mill is installed in the middle of each chamber of the steel ball mill; the sound sensor poin...

Abstract

The invention discloses a load detection method and device of a cylindrical steel ball mill. Multiple sound sensors and vibration sensors are used for simultaneous detection, and the noise and vibration of a certain section of the cylindrical steel ball mill are fused by fuzzy reasoning to obtain the cylindrical load. The load of this section of the steel ball mill, the load of each section of the cylinder ball mill cylinder is weighted and averaged to obtain the overall load of the cylinder ball mill; the test results are based on the load of each section of the cylinder ball mill and the overall load of the cylinder ball mill It is given that the monitoring of the operation status of the cylindrical steel ball mill is more comprehensive, reasonable and reliable. The device is composed of a distributed wireless network, which facilitates the selection and layout of measuring points, and is more reliable and easy to maintain. The method and device proposed by the invention overcome the disadvantages of previous detection methods such as being susceptible to interference, poor sensitivity, and poor linearity, and can effectively monitor the load of the cylindrical ball mill, providing guarantee for the optimal control of the load of the cylindrical ball mill.

Description

technical field [0001] The present invention relates to a detection method and device, in particular to a load detection of cylindrical steel ball mills widely used in industries such as thermal power plants and cement plants. Sensors, the load of each section of the barrel ball mill is obtained through multi-sensor fusion; the overall load of the barrel ball mill is obtained by fusing the loads of each section of the barrel ball mill; the device using this detection method is composed of a distributed structure , transmit relevant detection data through the wireless network, complete the analysis and processing of all data in the fusion center, and provide the results for display and other system use. Background technique [0002] Cylinder ball mills are widely used in various industries such as power generation, cement, mineral processing, ceramics, and metallurgy. As important equipment and large power consumers in these industries, they are crucial to the safe production...
