Device and method for on-line sample preparation and detection of powder material

Abstract

The invention provides a powder material on-line sample preparation detection device and method. The device comprises a disc-shaped shell and a pre-welding piece, a first opening is formed in the disc-shaped shell, an opening channel is formed in the pre-welding piece, the disc-shaped shell is communicated with the pre-welding piece through the first opening and the opening channel, and the pre-welding piece is used for being welded to the side wall of an air chute of a production line. A detection hole is formed in one side surface of the disc-shaped shell; a trowelling scraper is fixedly mounted at the first opening of the disc-shaped shell, and the trowelling scraper is arranged on the outer side of the opening channel; a second opening is formed in the side, opposite to the trowelling scraping plate, of the opening channel, and a supplied material baffle is fixedly inserted into the second opening. According to the invention, a powder material sample can be automatically extracted from a pipeline, the surface of the sample is flattened, and element components of the sample are monitored and analyzed on line; and furthermore, the sample after detection can be sent back to the pipeline.

Description

Technical field [0001] The present invention belongs to the field of material online detection, and more particularly to the apparatus and method of a powder material in line. Background technique [0002] In the existing cement production, the production enterprise needs to sample the products of various work segments in the production line, and samples, sample, and sends a chemical laborator in the production line. Detection and analysis of parameters such as elemental composition of the sample, particle size. [0003] The existing testing equipment does not automatically sample detection function, and can only be sampled from the production line by the sampler, and then the test room is transmitted to test. The entire process has low work efficiency, poor real-time, and the sample is easily contaminated, and the test results are more disturbed by people. Inventive content [0004] In response to the above problems, the present invention provides a device and method of a powde...

AI Technical Summary

Problems solved by technology

[0003] However, the existing testing equipment does not have the function of online automatic sample preparation and testing. It can only take samples from the production line regularly through the sampler, and then send them to the laboratory for testing.

The whole process has low work efficiency, poor real-time performance, samples are easily contaminated, and the test results are greatly disturbed by human factors.
