Problems solved by technology

[0006] Sampling, sample preparation, particle size detection, and moisture detection of conventional materials are manual operations with high intensity and low efficiency. Due to the high intensity of personnel work, the number of samples used is often small and the representativeness is not enough.

Embodiment 2

[0037] Using the control system of material intelligent sample preparation and detection in Example 1 to carry out processes such as material identification, transfer, shrinkage, crushing, drying, detection, grinding, marking, and discarding,

[0038] This control method comprises the steps:

[0039] The types of iron ore include fine ore, lump ore and pellet ore. The sampling quantity of each batch of iron ore entering the factory is 5-10 barrels, requiring 10kg / barrel, but the actual sample volume in the barrels taken out is 6-11kg.

[0040] (1) Parameter setting: Fine ore, the number of samples taken out is 5 barrels. Moisture is measured in each barrel, the sample size is 1kg, and the batch sample moisture is calculated. The particle size is required to be divided into 2kg from each barrel for batch measurement, and the particle size is 6.3mm and 10mm. The batch sample is 1kg for inspection, and the chemical composition sample is 120 mesh 100g.

Embodiment 3

[0047] Utilize the material intelligent sample preparation and detection control system of embodiment 1 to carry out processes such as material identification, transfer, shrinkage, crushing, drying, detection, grinding, identification, and discarding materials. The control method includes the following steps:

[0048] The types of iron ore include fine ore, lump ore and pellet ore. The sampling quantity of each batch of iron ore entering the factory is 5-10 barrels, requiring 10kg / barrel, but the actual sample volume in the barrels taken out is 6-11kg.

[0049] (1) Parameter setting: Lump ore, the number of samples taken out is 5 barrels. Moisture is measured in each barrel, the sample size is 1kg, and the batch sample moisture is calculated. The particle size is required to be divided into half from each barrel for batch measurement. The particle size is 9.5mm and 16mm. The batch sample is 1kg, and the chemical composition sample is 120 mesh 100g.

Abstract

The invention relates to a control system and method for intelligent sample preparation and detection of materials. The control system comprises a robot, a sample feeding device, a primary quantitative division machine, a jaw crusher, a secondary quantitative division machine, a vertical disc grinder, a moisture weighing device, a sample holder, a drying oven, a screen frame, a sweeping device, abelt type sample divider, an inspection screening machine, a granularity weighing device, a bag type automatic packaging machine and a computer. The states of devices for material feeding identifying,transferring, dividing, crushing, discharging, drying, grinding, detecting, marking, cleaning and the like are controlled by a computer through equipment function design, so that continuous operations of identifying, dividing, granularity measuring, moisture measuring, chemical component sample preparation and material information tracking of materials are realized, and the operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a control system and method for intelligent sample preparation and detection of materials, belonging to the field of intelligent detection of materials. Background technique [0002] Iron ore is the main raw material for ironmaking. Fluctuations in indicators such as iron, sulfur, phosphorus, and particle size directly affect the production of ironmaking blast furnaces and the quality of molten iron. Iron content, particle size, and moisture also directly affect procurement costs, which are of great significance to ironmaking and smelting. [0003] Conventional iron ore sample preparation process: use mechanical sampling on the conveyor belt entering the stockyard, manually send the sample to the sample preparation room, and then manually operate, first coarsely crush to 30mm with a large crusher, shrink several times to the specified amount, and then Use a medium-sized crusher to crush it to less than 6mm, then shrink it sever...
