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, screening, weighing, and reduction. Background technique [0002] At present, most of the existing equipment is a single working equipment, and then the work flow system is artificially formed, and each link requires manual feeding and reclaiming. For example, grinding equipment, screening equipment, reduction equipment. Moreover, in the existing grinding equipment (such as a disc grinder), the sample enters the grinding disc from the feed funnel, and the gap between the two grinding discs is manually adjusted to control the particle size of the discharged sample. The gap between the grinding discs requires manual Adjustment, the grinding cavity has defects such as material storage. In the existing dividing equipment, the motor drives the dividing tube to move in a circular motion. The sample enters the dividing tube from ...

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.
