Problems solved by technology

[0004] In the existing technology, the samples are usually stored directly in plastic bags. The samples in this storage method are very susceptible to deterioration due to factors such as temperature, humidity, sunlight, dust, and air, resulting in deviations in retest results. , at the same time, when storing samples in the prior art, it is necessary to manually use containers such as measuring cups to hold samples, and the operation is relatively cumbersome;

Abstract

The invention relates to the technical field of heavy non-ferrous metal concentrates, and discloses a sample retention device used for heavy non-ferrous metal concentrate. The sample retention device comprises a collection box, an inner cavity is transversely formed in the interior of the collection box, a movable bearing is movably arranged on the inner wall of the inner cavity, a rotating rod is fixedly installed on the inner wall of the movable bearing, and a spiral blade is arranged on the outer wall of the left side of the rotating rod. A second rotary knob is screwed to enable a lead screw to rotate, the lead screw rotates to drive a nut to move left and right, the nut moves left and right to drive a push block to move left and right through a push rod, the push block moves left and right to drive the movable bearing to move left and right, when the movable bearing moves leftwards, the rotating rod can extend out of the inner cavity, after the rotating rod extends out, the rotating rod can be rotated by screwing a first rotary knob, the rotating rod rotates to scrape a sample through the spiral blade on the outer wall of the rotating rod, the sample enters the inner cavity along the spiral blade, the sample in the inner cavity enters a storage cavity through a communication groove, and therefore, sample retention is completed.

Description

technical field [0001] The invention relates to the technical field of heavy nonferrous metal concentrates, in particular to a sample storage device for heavy nonferrous metal concentrates. Background technique [0002] my country is a big importer of heavy non-ferrous metal concentrates, and a large amount of heavy non-ferrous metal concentrates are imported every year; the inspection contents of imported heavy non-ferrous metal concentrates include sampling, sample preparation, moisture determination, solid waste identification, detection of toxic and harmful elements, weight Identification, copper, gold and silver content inspection and other inspection items; when there are safety, environmental protection, data deviation and other problems in the heavy non-ferrous metal concentrate, the traceability of the sample is very critical. Therefore, in the actual operation process, the sample must be effectively retained , so as to re-inspect later to ensure that the inspection r...
