Automatic-sampling-type online X-ray fluorescence analysis device of cement raw material

Abstract

The invention discloses an automatic-sampling-type online X-ray fluorescence analysis device of a cement raw material. The automatic-sampling-type online X-ray fluorescence analysis device comprises asampling mechanism used for trace sampling, a receiving mechanism used for quantitative sampling, an X-ray fluorescence measuring mechanism used for element component analysis, and a clearing mechanism used for sweeping and dust discharging. Trace sampling is conducted at a contact constant speed from a raw material chute through a miniature spiral reamer; the sampling amount is controlled through the receiving mechanism with a two-stage material level sensor and a two-stage shutter to achieve quantitative sample feeding for the X-ray fluorescence measuring mechanism; excess materials and samples are discharged back into the raw material chute again through a pneumatic conveyor; and the whole set of device continuously and circularly operates, it is ensured that the material amount of thesamples for the online X-ray fluorescence measuring mechanism is stable, and timeliness and representativeness of the samples are high.

Description

technical field [0001] The invention relates to the field of on-line detection of industrial material components, in particular to an on-line X-fluorescence analysis device for cement raw materials. Background technique [0002] Cement raw meal is an important source of cement production. In the cement production process, cement raw meal determines the product quality of cement clinker to a large extent and affects the economic benefits of enterprises. The production of cement raw meal is composed of four process links: mine mining, raw material pre-homogenization storage yard, raw meal grinding, and raw meal homogenization warehouse. Limestone, clay and other raw materials are ground into loose fine powder by raw meal mill Shaped raw meal, the air conveying chute driven by the fan airflow makes the raw meal in a suspended state along with the airflow and is transported to the raw meal homogenization warehouse along the pipeline, and then enters the kiln for calcination to f...
