Technical Field

The utility model relates to the technical field of fire test, in particular to an automatic batching system for a fire test method.

Background

The fire gold test method has wide applicability, good enrichment effect, good sampling representativeness and high accuracy of analysis results, and is considered as an important means for gold and silver analysis and an important method for gold arbitration. According to national standards of GB/T7739.1-2019 gold concentrate mineralization analysis method-gold quantity and silver content determination, the fire gold test process flow comprises six main steps of batching, mixing, melting, ash blowing, gold separation, weighing and the like. The specific process of the batching operation is as follows: firstly, calculating the addition values of seven reagents (sodium carbonate, borax, lead oxide, flour, glass powder, silicon dioxide and glass powder) according to the characteristics of a sample; and weighing seven reagents and samples to be tested on an analytical balance respectively to target mass, and filling the target mass into a sample container (crucible) to finish batching, so that subsequent mixing operation is performed.

Currently, most fire test laboratories still use a manual dosing mode of operation, including manual calculation of dosing schemes, where reagents are manually weighed on a scale using a weighing scoop. Because each batch of detection tasks is generally 20-40 samples, the addition amount of seven reagents related to each sample needs to be calculated, and then the seven reagents are manually weighed and added into a crucible one by one according to the calculated amount, the working efficiency is low, the repeatability is high, and meanwhile, dust of harmful reagents is easy to raise in ingredients, so that the method has certain health hazard to practitioners. The patent with the application number of CN 207730525U discloses an automatic batching machine for detecting gold and silver samples by a fire test method, which comprises hoppers, feeders, weighing hoppers, mixing hoppers and blanking machines, wherein the number of the hoppers corresponds to the number of the types of the batching to be mixed, the outlet of each hopper is respectively communicated with the inlet of one feeder, and the weighing hoppers are correspondingly arranged below the outlet of each feeder; the outlets of all weighing hoppers are communicated with the inlets of the mixing hoppers; the outlet of the mixing hopper corresponds to the inlet of the blanking hopper of the blanking machine; the automatic batching machine also comprises a material containing crucible, wherein the material containing crucible is arranged on a movable conveying mechanism; and the feeder, the weighing hopper, the mixing hopper and the blanking machine are all electrically connected to the PLC control terminal. The sample to be tested of the batching machine can be directly added to the bottom of the crucible before batching or added to the top of batching after batching, so that the sample to be tested cannot be added to various raw materials, and uneven mixing and poor enrichment effect are easily caused.

In view of the foregoing, there is a need for an improved automated batching system for fire testing methods that solves the above-mentioned problems.
