Reduction device in full-automatic material sample preparation and application

Abstract

The invention discloses a reduction device for reducing sample materials in the transportation process during full-automatic material sample preparation. The reduction device comprises a machine frame, and is characterized in that the machine frame is provided with a feeding opening, a sampling opening, a sample rejecting opening and an annular net belt driven by power, standing columns are arranged on all chain plates for forming the net belt, containers for assembling and disassembling samples are installed on the standing columns through shafts at the two ends, and can surround the standing columns to rotate, openings of the containers are kept upward, and touching blocks are arranged on shafts at one ends of the containers; sample rejecting touching rods which correspond to the touching blocks and are installed on the machine frame are arranged at the sample rejecting opening, sampling touching rods which correspond to the touching blocks and are installed on the machine frame are arranged at the sampling opening, and the sampling touching rods are controlled by a sampling control mechanism to move to allow the sampling touching rods and the touching blocks to be touched or be not touched; the reduction device is applied to full-automatic material sample preparation; according to the reduction device, the net belt serves as a transmission tool of samples; meanwhile, samples of materials are reduced in the transportation process, a device of a full-automatic material sample preparation system is simpler, the structure is compact, and the device cost is reduced.

Description

technical field [0001] The present invention relates to a kind of sample preparation of materials, in particular to a shrinking device and application in automatic sample preparation of materials, in particular to a material which shrinks and divides samples of materials during transportation The shrinking and dividing device and its application in automatic sample preparation. Background technique [0002] In the late 1990s, the sample preparation technology of domestic materials (such as coal, ore, etc.) was in a relatively backward state, and its sample preparation work basically relied on manual operations. In 1999, the first domestic crushing and shrinking joint sample preparation unit integrating two crushing and two shrinking was launched on the market, which was unanimously recognized by domestic customers. It basically freed the sample preparation work from tedious manual operations and realized the Semi-automatic sample work; not only reduces the intensity of manu...

Problems solved by technology

[0004] However, the use of a disc shrinking machine is prone to blockage and sticky materials. First, it will cause cross-contamination of the sample and affect the representativeness of the sample. Second, it will affect the normal and stable operation of the equipment.

In addition, the shrinking equipment and transportation equipment in the automatic sample preparation system are separated, which makes the structure of the entire sample preparation equipment complex and occupies a large area.
