Reducing feeder for fire assaying preparation

Abstract

The invention discloses a variable-diameter feeder for preparing fire assaying, which comprises a sample melting device for receiving fire assaying powder, a frame body for mounting an integral part, a feeder for storing and conveying the fire assaying powder, a conveying belt for carrying the sample melting device and a control console, and a feeding mechanism is mounted at one end of the frame body; the feeding mechanism is composed of at least six sets of two-degree-of-freedom components in an annular array mode, each two-degree-of-freedom component is composed of a rotating pair and is driven by a moving pair, and the feeding mechanism comprises a barrel and a sliding frame. By means of mechanical linkage and mutual cooperation of the feeding mechanisms, variable-diameter discharging can be conducted on sample melters of any size or any structural characteristic in the actual use process, and powder output at a specific angle is achieved by changing the diameter and the internal taper of a mechanical structure; the phenomena of scabbing and overflowing in the prior art are avoided, the quality precision requirement of an actual sample melting device is effectively ensured, and the requirement of subsequent reaction detection is met.

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
