A sample preparation system

Abstract

The invention relates to a sample preparation system. The system comprises a grinding mechanism for grinding samples to be machined, a screening and weighing mechanism communicating with a grinding discharge port of the grinding mechanism through a screening feed port thereof and used for screening and weighing qualified samples and returning unqualified samples to the grinding mechanism, and a reduction mechanism for reducing the qualified samples according to a set reduction ratio. The sample preparation system integrates grinding, screening, weighing and reduction to 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. Moreover, in the existing grinding equipment (such as a disc grinder), the sample enters the grinding disc from the feeding 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 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 motion, the ...

Moreover, in the existing grinding equipment (such as a disc grinder), the sample enters the grinding disc from the feeding 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 grinding. 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.
