An automatic sample pulverizer

Abstract

The invention discloses an automatic sample preparation pulverizer, comprising a frame, a control component, a powder making component, a hopper, a collection channel, a sample discarding channel and a sample retention channel, the hopper is located at the feeding end of the powder making component, The collection channel communicates with the discharge end of the pulverizing assembly, the sample discarding channel and the sample retention channel are located at the discharge end of the collection channel, and the feed end of the hopper is provided with a set for dividing the material into retention samples and cleaning A sample divider for the sample, the bottom of the sample divider is provided with a drive mechanism for unloading the reserved sample and a drive mechanism for unloading the cleaned sample to perform unloading operations on the reserved sample and the cleaned sample respectively. The invention has the advantages of simple and compact structure, can further improve the crushing precision of sample preparation and the like.

Description

technical field [0001] The invention mainly relates to the field of sample preparation equipment, in particular to an automatic sample preparation pulverizer. Background technique [0002] In many technical fields of the prior art, it is necessary to make material samples. For example, in the field of coal sample testing, it is necessary to make a representative coal sample before performing various tests on the coal sample. In the production process, it is often necessary to crush the coal samples first and then collect them. During this period, there must be no loss of samples, and no physical or chemical changes in the samples, otherwise the final test results will be affected. [0003] In the sample preparation process, the automatic sample preparation pulverizer is often used, which uses a crushing tool to crush the materials fed from the hopper, and then directly introduces the crushed materials into a bottle for collection. . In this process, the following problems...

AI Technical Summary

Problems solved by technology

[0004] 1. A large amount of dust or fine particles will be generated during the crushing process, which will easily remain and adhere to the crushing tool and the inner wall of the crushing chamber, resulting in loss of samples, and is not conducive to disassembly and cleaning

[0005] 2. The degree of automation is not high, and it is often necessary to manually switch between retaining or discarding samples, and the labor intensity of feeding operations is high

[0006] 3. In the process of sample preparation, residual samples are often adhered to various parts, which will affect the accuracy of sample preparation for the next sample preparation.
