Abstract

The invention provides an ore pulp sampling and iron grade signal collection device and method, and relates to a sampling device and method. The device and the method aim at solving the problems thatthe existing sampling device only has a single sampling function; after sampling, the materials need to be transferred into a laboratory for measuring ore slurry iron grade, so that the work procedures are complicated. The device provided by the invention comprises a dustproof cap, a handle, a sampling tube, a measuring rod, a compression spring and a sampling tube lower end cover, wherein the lower end of the handle is connected with the upper end of the sampling tube; the measuring rod sequentially penetrates through the handle and the sampling tube from top to bottom; the lower end of the measuring rod is inserted into the upper surface of the lower end cover of the sampling tube; the dustproof cap sleeves the upper end of the measuring rod; the ore slurry sampling and iron grade signalcollection device further comprises a sensor measuring head and a fastening screw; the sensor measuring head sleeves the outer side wall of the upper part of the sampling tube; and the lower part ofthe sensor measuring head is fixedly connected with the sampling tube through the fastening screw. The device and the method provided by the invention are used in the technical field of industrial mineral separation.

Description

technical field [0001] The invention relates to a sampling device and method, in particular to an ore pulp sampling and iron grade signal acquisition device and method. Background technique [0002] In the process of industrial mineral processing, in order to determine the quality of iron ore pulp in different batches and processes, it is necessary to sample and analyze the pulp at different depths in the pulp tank in the mineral processing process. The results of the analysis and testing can provide data for optimizing the process flow and fine-tuning production equipment parameters For reference, the traditional slurry sampler only has a single sampling function, and after sampling, it needs to be transferred to the laboratory for measurement of the iron grade of the slurry. The laboratory chemical analysis method is accurate, but the process is cumbersome and the test cycle is long. Contents of the invention [0003] The present invention solves the problem that the exi...
