Embodiment Construction

[0013] The preferred embodiment of the on-line measuring device for pulp grade of the present invention is as follows: figure 1 Shown:

[0014] Including a pulp sample carrying device, the pulp flow flows through the pulp sample carrying device, one side of the pulp sample carrying device is equipped with an X-ray tube and an X-ray detection device, and the X-ray tube is connected to a high-voltage power supply;

[0015] The high-voltage power supply is used to make the X-ray tube generate X-rays to irradiate the pulp flow in the pulp sample carrying device. The characteristic X-rays generated by the excited pulp flow are detected by the X-ray detection device, and the X-ray detection device transmits the detection signal to Signal processing unit.

[0016] The signal processing unit processes the received detection signal, calculates the element content in the pulp and displays or outputs it through the man-machine interface.

[0017] It may also include a temperature contr...

Abstract

The invention discloses a pulp grade online measurement device, which comprises an X-ray tube, a high-voltage power supply, an X-ray detection device, a pulp sample carrying device, a signal processing unit, a temperature control system, a human-computer interface and the like. High-voltage power is applied to the X-ray tube to generate X rays which are taken as an excitation source irradiating pulp in the pulp sample carrying device to generate characteristic X rays; the X-ray detection device receives the characteristic X rays and detects signals corresponding to the characteristic X rays; and the signal processing unit receives the characteristic X ray signals, and analyzes and calculates the grade of the pulp sample element. The pulp grade online measurement device has the characteristics of high excitation capacity, high measurement accuracy and no nuclear pollution. The grade of the pulp sample element is displayed or output by the human-computer interface; and the temperature control system controls the temperatures of the X-ray tube and the X-ray detection device so as to ensure constant temperature to further ensure stable measurement.

Description

technical field [0001] The invention relates to an ore pulp grade detection technology, in particular to an on-line measurement device for ore pulp grade. Background technique [0002] The on-line analysis technology of pulp grade in the mineral processing industry has a wide range of applications, and the use of X-ray fluorescence analyzers for ore grade analysis has many advantages. [0003] X-ray fluorescence analyzer is a kind of pulp grade analysis that uses primary X-ray photons or other microscopic ions to excite atoms in the mineral substance to be tested to produce fluorescence (secondary X-ray) for mineral composition analysis and chemical state research. instrument. It mainly includes excitation, dispersion, detection, recording and data processing units. [0004] The pulp grade analyzers in the prior art all use radioactive elements as excitation sources. [0005] There are at least the following disadvantages in the above-mentioned prior art: [0006] The ex...
