Abstract

The invention discloses a powder pressing sampling device for X ray fluorescence analysis. The powder pressing sampling device comprises a bottom plate; a supporting seat is arranged on the bottom plate, and a hydraulic pump is mounted on the supporting seat; an oil sac communicated with an oil inlet line and an oil return line in the hydraulic pump is arranged at the top of the hydraulic pump, and a valve for regulating the opening and closing of the oil return line is arranged on the side face of the hydraulic pump; a transmission mechanism is arranged on the side wall of the hydraulic pump; a pressing plate is mounted on a piston rod at the lower end of the hydraulic pump; a mold pressing mechanism is fixedly mounted on the bottom plate and just under the pressing plate and comprises a mold pressing plate and a fixed seat fixed on the bottom plate; a mold pressing cavity is movably formed in the fixed seat, and a first spring sleeves the fixed seat and is positioned between the bottom of the mold pressing cavity and the bottom plate; a first groove is formed in the lower surface of the mold pressing plate, and a second groove is formed in the upper surface of the mold pressing plate. During sample pressing, a sample in a containing cavity is gradually compressed along with the shrinkage of the containing cavity, sample particles are crushed under the action of pressure, and therefore the flatness of the pressed sample is ensured.

Description

technical field [0001] The invention relates to a machine for pressing samples, in particular to an X-ray fluorescence analysis powder sample pressing device. Background technique [0002] When conducting geological surveys or environmental soil heavy metal pollution detection in the field, it is often necessary to quickly and accurately analyze the element content of samples on site. Due to the uneven particle size of the sample collected on site, the flatness of the pressed sample is difficult to meet the measurement requirements. Using a manual sample press on the market to perform X-ray fluorescence analysis on this uneven sample will make the analyzed The element content error is large. The hydraulic sample pressing equipment in the laboratory is bulky and heavy and not easy to carry. Difficult to use in the sampling field. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to prov...
