A variable-diameter feeder for fire assay gold preparation

Abstract

The invention discloses a variable-diameter feeder for fire test gold preparation, which includes a melting device for receiving fire test gold powder, a frame responsible for installing integral parts, a feeder for storing and transporting fire test gold powder, and carrying the melt test gold powder. Conveyor belt and console of sampler, one end of the frame body is equipped with a feeding mechanism; It is composed of a rotating pair and is driven by a moving pair. The feeding mechanism includes a cylinder and a slide frame; the present invention can be used for any size, A fuser of any size or any structural characteristics is used to change the diameter of the material, relying on changing the diameter of the mechanical structure and the form of the internal taper to achieve a specific angle of powder output, which will not cause scabbing and overflow in the prior art, effectively ensuring The mass accuracy requirements of the actual fusion device meet the requirements of subsequent reaction detection.

Description

technical field [0001] The invention relates to the technical field of fire assay gold, in particular to a variable-diameter feeder for fire assay gold preparation. Background technique [0002] Fire assay gold is an ancient process, which can be traced back to the ancient Roman period two thousand years ago; after many technical iterations and updates, the modern fire assay gold process is a form of exploration geochemistry, and its specific application is Mineral exploration using geochemical principles is aimed at locating the geographic location of sedimentary deposits and the extension of discovered deposits by chemical methods. Usually, fire test gold exploration samples are made of cores, rocks, river sediments, soil, and glacial cuttings. or vegetation, etc., are ground into flour and processed through a specific reactor or sootblower; [0003] Under normal circumstances, the preparation of fire test gold is stored by the sample fusion device of the feeder, and the ...

Problems solved by technology

[0003] Under normal circumstances, the preparation of fire test gold is stored by the sample fusion device of the feeder, and the powder quality is strictly limited to carry out fire test gold operation according to the corresponding process steps, so as to meet the needs of accurate detection and perfect exploration records; As shown in the Chinese Patent Publication No. CN207730525U, which was disclosed on August 14, 2018, as shown in a kind of automatic batching machine for detecting gold and silver samples by the fire test gold method, in this type of traditional technology, the fusion device The fire test gold powder storage is usually done by grinding the material into powder by the feeder, but limited by the structure of the actual parts, the storage of the powder is prone to overflow or mist, which is easy to cause quality errors; the rubber tube cover is used Although the traditional solution to the fusion device can initially solve this phenomenon, as the use time increases, a large amount of powder scab will accumulate inside the tube body. Under different test samples or batches, the powder scab at the front is easy Falling into the fuser of the fire test gold sample at the back, it can meet the quality inspection process, but it can cause errors to the test data
