The invention provides an electromagnetic fine iron powder sampling and grade information acquisition device, and belongs to the field of fine iron powder sampling and grade information acquisition. The device is characterized by comprising an electromagnetic adsorption device and a connection detection device; an electromagnet is arranged on the upper portion of a sampler and has adsorption acting force when powered on; when a partition plate is opened, a sample is sucked into a sampling barrel; the number of turns of a coil of the electromagnet can be adjusted at will according to the magnetic attraction force requirement; by presetting coil power-on time and power-off interval time, the iron core becomes magnetized and produces a magnetic force to collect the sample; and after the coilis powered on and powered off, the partition plate is closed when the coil is powered off, the sample falls off from the plastic cutting plate under the action of gravity and enters a detection samplecup through the connecting pipeline, and the mutual inductance type inductance sensor detection probe can rapidly detect the sample. The electromagnet is adopted as an adsorption device, the structure is novel, unique, simple and convenient, the working efficiency is improved, achievement transformation is convenient, sampling is safe, and production and research are guided conveniently.
Description
technical field [0001] The invention relates to the field of iron fine powder sampling and grade information collection, in particular to an electromagnetic type iron fine powder sampling and information collection device. Background technique [0002] The demand for modern high-grade iron ore is increasing year by year. Most of the iron ore distribution in my country is lean ore. The mineral resources such as associated ore are of low grade, and the ore segment is complex. It is not suitable for direct use in steel or iron making. The ore undergoes fine processing such as crushing, grinding, magnetic separation, flotation, gravity separation, etc. to improve the detection level of the ore, and obtain high-grade iron powder. From a technical point of view, there is an urgent need for advanced technology, equipment and automatic detection technology to realize the grade monitoring in the process of beneficiation and iron ore transportation. In the process of industrial benefi...
