Sample preparation system

Abstract

The present invention relates to a sample preparation system, and the system comprises a grinding mechanism for grinding a sample to be processed; a screening and weighing mechanism, wherein a screening feed port of the screening and weighing mechanism is communicated with a grinding discharge port of the grinding mechanism, the screening and weighing mechanism is used for screening and weighing qualified samples, and unqualified samples return to the grinding mechanism; and a division mechanism which is used for carrying out division treatment on the qualified sample according to a set division ratio. The sample preparation system integrates grinding, screening, weighing and splitting, and can realize automatic sample preparation.

Description

technical field [0001] The invention relates to the technical field of sample preparation, in particular to a sample preparation system integrating grinding, sieving, weighing and shrinking. Background technique [0002] At present, most of the existing equipment are single-working equipment, and then the workflow system is artificially composed, and each link needs manual feeding and retrieving. For example, grinding equipment, screening equipment, shrinking equipment. And, in existing grinding equipment (such as disc grinder), wherein the sample enters the grinding disc from the feed funnel, by manually adjusting the gap between the two grinding discs, the particle size of the discharged sample is controlled, and there is a gap between the grinding discs that requires manual grinding. Adjustment, there are defects such as material storage in the grinding chamber. In the existing shrinking and dividing equipment, the motor drives the distributing pipe to make a circular m...

AI Technical Summary

Problems solved by technology

And, in existing grinding equipment (such as disc grinder), wherein the sample enters the grinding disc from the feed funnel, the gap between the two grinding discs is manually adjusted to control the particle size of the discharged sample, and the gap between the grinding discs needs to be manually adjusted. Adjustment, defects such as material storage in the grinding chamber

In the existing shrinking and dividing equipment, the motor drives the distributing pipe to make a circular motion, and the sample enters the distributing pipe from the static funnel. The angled discharge collection port can separate samples that account for a certain proportion of the total sample. There are defects such as the shrinkage ratio needs to be manually adjusted, and the shrinkage samples cannot be automatically bagged.
