Powdery material sample riffle divider and using method thereof

Abstract

The invention belongs to the technical field of measurement and detection devices and in particular relates to a powdery material sample riffle divider and a using method of the powdery material sample riffle divider. The sample riffle divider is characterized by comprising a turning charging basket and a distributor which is arranged in the turning charging basket, wherein the turning charging basket comprises a base, a bracket arranged on the base, a charging basket which is arranged on the bracket and is rotationally connected with the bracket through a pair of turning shafts, and a locking pin which is arranged on the bracket and is positioned below one turning shaft; the distributor comprises two distribution plates which are vertically arranged and are criss-cross, two striker plates which are arranged at the top ends of the two distribution plates and are arranged diagonally, a handle arranged at the top ends of the two distribution plates, and two lock catches which are respectively arranged on the two striker plates. The powdery material sample riffle divider is simple in structure, accurate in division and convenient to clean. The upper part of the charging basket is cylindrical, the lower part of the charging basket is conical, the distribution plates are accurately positioned, and materials are uniformly distributed. The bottom of the charging basket is in the shape of a pan bottom, thus the powdery material sample riffle divider is convenient to clean and operate.

Description

technical field [0001] The invention belongs to the technical field of mineral processing and sampling, and in particular relates to a powder material sample dichotomizer and a method for using the same. Background technique [0002] At present, in the fields of cement, metallurgy, chemical industry, etc., there are the following methods and devices for subdivision sampling of solid powder material analysis equipment: 1. Manual sampling: After mixing the samples with common tools, they are divided into equal parts. A certain amount of samples are taken from each part. The sampling device of this method is simple, but it is laborious, time-consuming, and polluted by dust, which is harmful to the health of operators. 2. Separated sampling (sampling by aliquot method): fill the container with the sample, open the switch of the continuous lower three-sided cone-shaped partition, the sample can flow to both sides, and there are several vertical partitions on each side to slide do...

AI Technical Summary

Problems solved by technology

The main features are reasonable structure, easy to use, and multi-point shrinkage performance. However, the splitter is composed of many grid grooves with small width. It is small and contains starch components. It is easy to adhere to the traditional dichotomer, and it is very difficult to clean. If it cannot be cleaned, it will cause mixed samples and make the sample lose accuracy.

The above-mentioned sampling methods and their devices cannot meet the requirements of on-line sampling, and cannot realize continuous and uniform sampling of materials in the production process, causing the representativeness of the samples to be questioned
