A kind of lofting device for ash blowing furnace

Abstract

The invention discloses a lofting device for a cupellation furnace. The lofting device comprises two sample guiding frames, sample positioning frames and a pull rod. The left and right sample guiding frames are arranged on the inner sides of the left and right sample positioning frames. The sample guiding frames are connected to the left and right sample positioning frames through guiding grooves. An upper fixing plate and a lower fixing plate are arranged at the transverse positions of the left and right sample positioning frames. The fixing plates and the left and right sample positioning frames are fixedly connected. According to the lofting device for the cupellation furnace, the problem that time is wasted when lead button samples are placed manually one by one can be solved, the lead button sample placement efficiency is greatly improved, a plurality of lead button samples are placed at a time, meanwhile, the problem that the preheating temperature of the cupellation furnace is decreased in the lead button sample placement process is further solved, the re-preheating time of the cupellation furnace is shortened, and heat waste is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fire test gold ash blowing sample placement, in particular to a setting out device for an ash blowing furnace. Background technique [0002] Fire assay gold analysis is actually a gold assay method using a crucible or ash dish as a container. There are many types and different operating procedures. Among all fire assay gold methods, the most commonly used and most important is the lead assay gold method. Its advantage is that the obtained lead button can be ash blown; the lead fire assay method is mainly divided into three different stages of smelting, ash blowing, and gold separation. In the smelting stage, a lead alloy is formed, that is, a lead button sample, and the lead button sample needs to enter the The next stage is ash blowing. The process of ash blowing is carried out in the ash blowing furnace. In this way, the lead buckle sample needs to be placed on the ash dish, the ash dish is placed on th...

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a lofting device for an ash blowing furnace, which has a scientific and reasonable design, a simple structure, and is easy to use; it can solve the problem of slow placement of lead buckle samples one by one manually, and greatly improves the test efficiency of placing lead buckle samples. The same efficiency has realized the placement of multiple lead buckle samples at one time, and also solved the problem of reducing the preheating temperature of the ashblowing furnace during the process of placing the lead buckle samples, shortened the time for the ashblowing furnace to preheat again, and greatly reduced waste of heat
