Description
Technical Field
The invention relates to the technical fields of geology, metallurgy, energy conservation, environmental protection and steel, in particular to an automatic magnetic separation sample injector for iron ore and magnetic iron in a laboratory and a using method thereof.
Background
At present, in the laboratory for the phase analysis of iron ore, the measurement of magnetic iron (mFe) is required. There are two methods for measuring magnetic iron, one being a manual internal magnetic separation method and the other being a magnetic separator method, according to the relevant provisions of the industry Standard (DZ/T0200-2002) and rock mineral analysis (fourth edition).
Wherein, the manual internal magnetic separation method comprises the following steps: generally, 0.2 g of iron ore sample is weighed, an operator uses a purge bottle to wash the iron ore sample step by step, the iron ore sample is completely transferred into a container such as a culture dish (or a glass beaker) and the like, a proper amount of water is added to shake the iron ore sample evenly, a permanent magnet is placed into a copper sleeve (or a glass tube) with one closed end, then the copper sleeve (or the glass tube) is immersed into the iron ore sample to be stirred, magnetic iron in the sample is adsorbed on the outer wall of the copper sleeve (or the glass tube) due to the magnetic force, the permanent magnet is removed, the magnetic iron adsorbed on the outer wall of the copper sleeve (or the glass tube) is washed in another culture dish or the glass beaker by water, and the operation is repeated until the magnetic iron is completely magnetically.
Magnetic separator method: at present, a WFC-1 type physical phase analysis magnetic separator is commonly used in a laboratory for carrying out magnetic separation on iron ore samples, and the magnetic separator consists of a frame, a transmission system and a leaching device. The frame is used for vertically clamping and placing a glass magnetic separation tube (generally an acid glass burette); the transmission system is mainly a permanent magnet arranged on the motor, the permanent magnet is close to the magnetic separation tube, and when the magnetic separation tube works, the permanent magnet reciprocates up and down along the outer wall of the glass magnetic separation tube at a certain frequency in the vertical direction; the leaching device mainly comprises tap water and a water stop clamp, and is uninterruptedly used for flushing iron ore samples during magnetic separation and flushing nonmagnetic samples to a waste liquid container at the lower part of the magnetic separation tube. When the permanent magnet lifting device works, the motor is started, and the permanent magnet starts to move up and down in a reciprocating manner; and (2) starting water flow, blowing and washing 0.1-0.5 g of iron ore samples into the magnetic separation tube from the upper part of the magnetic separation tube by using a washing bottle by an operator, adsorbing magnetic iron in the samples on the inner wall of the magnetic separation tube under the magnetic action of a permanent magnet in the descending process of the samples due to gravity, turning over along with the up-and-down movement of the permanent magnet, and separating the samples from the nonmagnetic samples under the flushing of the uninterrupted rinsing water flow, thereby finishing the magnetic separation work. And (4) after the magnetic separation is finished, turning off the motor, taking down the magnetic separation tube, and washing the magnetic iron adsorbed on the inner wall of the magnetic separation tube into another beaker by using water until the magnetic separation work is finished.
The process devices and operation flows used in the industry at present have the following problems and disadvantages:
(1) from the two methods, no matter the manual internal magnetic separation method or the magnetic separator method, at the beginning of magnetic separation, 0.1-0.5 g of solid powdery iron ore sample is transferred into a culture dish (glass beaker) or a magnetic separation tube of the magnetic separator, and the manual operation is adopted, so that the unattended continuous production cannot be realized, the labor cost is high, the labor intensity is high, and the production efficiency is low.
(2) Because the manual sample introduction is carried out, the precision of the sample introduction of the iron ore is poor, the accuracy of the analysis and test is easily influenced and the quality of the analysis and test is influenced because the manual sample introduction is carried out and the manual actions, the washing times and the working experience of different operators are different.
