Inclined digestion tank heating backflow device

Abstract

The invention discloses an inclined digestion tank heating backflow device, which comprises a heating device casing, a heating block, heat transfer components, a cooling region and temperature sensing components, wherein the heating block is filled in the inner wall of the heating device casings; a plurality of digestion tank grooves used for accommodating digestion tanks are formed in the heating block; each digestion tank groove is in inclined arrangement; a heat transfer component and a temperature sensing component are arranged in each digestion tank. The inclined digestion tank heating backflow device has the advantages that the acid liquid condensing backflow can be realized in the heating process; the surface area of the liquid in the digestion tank is increased; the acid liquid evaporation is accelerated; the acid catching experiment speed is accelerated.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental sealed digestion device, which has the functions of heating reflux and heating to remove acid. Background technique [0002] When carrying out the digestion experiment, it is necessary to heat the digestion tank to evaporate the acid liquid to nearly dry. The existing heating device is vertically placed, and the digestion tank is also vertically placed in the heating device, resulting in a small surface area of ​​the acid liquid, which affects the evaporation rate and prolongs the experiment time; , the heating device of the entire digestion tank is integrated, the upper and lower layers start heating at the same time, and stop heating at the same time, which will cause the loss of metal elements with low boiling points during the heating process, affecting the detection results, and the temperature of the upper layer of the digestion tank is relatively high during the ref...
