According to the device, the online real-time detection problem of the ore pulp concentration is solved. The device comprises a feeding pipe, a discharging pipe, a sampling pump, an intelligent calculation module, a parameter detection module, a display module, a data communication module, wherein the intelligent calculation module adopts the online real-time detection method for the ore pulp concentration and is used for acquiring a real-time ore pulp concentration C according to detected pump motor power P and an acquired relation between an offline detection ore pulp concentration C and a sampling pump motor power P. Themethod and the device are simple and easy to implement, the later-period replacement and maintenance are easy, the maintenance cost is low, and a user can know that the measured precision meets the production requirements through comparison on offline data and online data of the ore pulp concentration.

Description

technical field [0001] The invention belongs to the field of measurement methods and devices, and in particular relates to an online real-time detection device and method for pulp concentration. Background technique [0002] In mining, metallurgy, coal and other production enterprises, there are strict technological requirements for the concentration of the produced pulp. A commonly used pulp concentration detection method is the manual measurement of the concentration pot, which is labor-intensive and requires not only manual weighing, but also manual table lookup, and the concentration measurement is seriously lagging behind. With the continuous improvement of the modernization level of the factory, online real-time detection of pulp is possible. Concentration becomes an urgent need for production. The existing online detection methods and devices for pulp concentration mainly include ultrasonic concentration meter and nuclear concentration meter. There are many factors t...
