Online detection method based on robot unit ore sample preparation system

Abstract

The invention discloses an online detection method based on a robot unit ore sample preparation system. The ore sample preparation system comprises a feeding belt conveyor, a primary division machine, a secondary division machine, a primary crushing machine, a secondary crushing machine, an electronic balance, a vibrating screen, an oven, a grinding and pulverizing machine, a robot and a waste belt conveyor; a device for performing sampling operation on samples can perform grabbing, placement and dumping operation among any technological process facilities by applying the robot and perform grain composition analysis, preparation of moisture and chemical samples and measurement of moisture content with an ore sample preparation method; sample preparation, grain size analysis and moisture detection of the robot unit ore sample preparation system can all be performed on the same plane, the flexible and maneuvering performance is good, and system devices can be added or reduced according to demands of work in the moving range of the robot; the mechanization and automation level is high, facilities in the system are concentrated and easy to maintain, and workers can be liberated from the operation links with potential safety hazard or in poor work environment.

Description

technical field [0001] The invention relates to an ore sample preparation method, which belongs to the field of mining equipment. Background technique [0002] At present, the technological process of the traditional large-scale mechanized iron ore sampling and preparation system in China is generally taken by the primary sampling machine, and then the sample is transported to the upper layer of the sampling tower through the transportation equipment or the primary sampling machine itself is on the top of the sampling tower. Then according to the needs of the process, the samples are sent from top to bottom through the chute or the feeder or the feeder sends the samples to the equipment such as particle size screening, sample shrinking, sample crushing, etc., to complete the sampling and preparation operation in the system , due to the limitation of equipment, this kind of process cannot realize the online measurement of moisture. Generally, the moisture samples taken are se...

[0002] At present, the technological process of the traditional large-scale mechanized iron ore sampling and preparation system in China is generally taken by the primary sampling machine, and then the sample is transported to the upper layer of the sampling tower through the transportation equipment or the primary sampling machine itself is on the top of the sampling tower. Then according to the needs of the process, the samples are sent from top to bottom through the chute or the feeder or the feeder sends the samples to the equipment such as particle size screening, sample shrinking, sample crushing, etc., to complete the sampling and preparation operation in the system , due to the limitation of equipment, this kind of process cannot realize the online measurement of moisture. Generally, the moisture samples taken are sent to the manual sample preparation room for moisture measurement. Due to the increase in storage and transportation links, the source of error also increases. Due to the process Due to the limitation, it is impossible to carry out particle size detection for most fine ores, ores with high moisture content and lump ores with many particle sizes. When encountering special materials with high viscosity or high total moisture in materials, these will affect the fluidity of materials and cause The sticking and blockage of the conveying pipeline and the interruption of material flow directly affect the safe operation of the system and the collection of complete samples, which greatly increases the operating cost and investment cost of the system
