A device and method for on-line detection of throughput of vibrating screen

Abstract

A vibrating screen treatment quantity on-line detection device and a vibrating screen treatment quantity on-line detection method belong to an on-line detection device and an on-line detection method. The acceleration value of a screen body of a vibration screen is detected by an acceleration sensor in real time, the speed value of the screen body of the vibration screen is detected by a speed sensor in real time, and the power of an exciting vibration motor is detected by a power meter in real time. According to a formula that m is equal to p / (v*a) and during no-load of the vibrating screen, the three sensor values are put into the formula to obtain the value m, recorded as m1, during no-load of the vibrating screen; the mass M screen body of the screen body of the vibrating screen provided by a manufacturer is divided by m1 to obtain correlation coefficient k; the correlation coefficient k, the mass M screen body of the screen body as well as the acceleration sensor value a, the speed sensor value v and the power meter value p during load production of the vibrating screen are utilized to perform calculation according to the formula as shown in the Specification to obtain the real-time processing quantity of the vibrating screen during work. According to the device and the method, the processing quantity of the vibrating screen can be detected accurately in real time, the structure is simple, the cost is low, mounting convenience is realized and reliability is high.

Description

technical field [0001] The invention relates to an on-line detection device and method, in particular to an on-line detection device and method for the throughput of a vibrating screen. Background technique [0002] As the key equipment in the coal preparation industry, the vibrating screen monitors the processing capacity of the vibrating screen in real time to ensure its normal operation, which is conducive to guiding the operation of subsequent sections. The existing calculation method of vibrating screen capacity is: [0003] Q=3600*b*v*h*ρ [0004] In the formula, Q is the processing capacity, the unit is t / h; b is the width of the screen machine, the unit is m; v is the material running speed, the unit is m / s; h is the average thickness of the material, the unit is m; ρ is the bulk density of the material , the unit is t / m 3 . [0005] Through the analysis, it can be judged that it is difficult to measure the material running speed, material average thickness, and ...
