Abstract

The invention relates to the technical field of coal quality analysis and test, and discloses a high-temperature sample rapid cooler which comprises a box body, wherein at least one placement notch for placing a cylindrical cupel is formed in the surface of the box body, and one side of the box body is fixedly connected with a water inlet pipe. Through the non-contact cooling of the operation assembly and the placement notch, the rotation of the cupel ensures that the whole circumferential surface of the cupel can fully and uniformly exchange heat with low temperature conducted by the placement notch, so that thermal stress generated by local quenching is effectively avoided, further, due to the action of gravity, impurities such as unburned gangue particles with higher density in the cupel can naturally settle and are always gathered at the bottom of the cupel, namely, the position closest to the placement notch with high thermal conductivity, so that the part with the maximum thermal resistance and more cooling energy is just in an optimal heat exchange area, and the cupel is suitable for underground laboratory sites with extremely high explosion-proof requirements.

Description

Quick cooler for high-temperature sample Technical Field The invention relates to the technical field of coal quality analysis and test, in particular to a high-temperature sample rapid cooler. Background The ash content of clean coal is one of the core indexes for measuring the quality of coal and pricing products. In the coal preparation production process, in order to guide washing and selecting operation in time, improve the yield of clean coal and ensure stable product quality, a quick ashing method is generally adopted to carry out quick inspection on clean coal samples, namely, a cupel containing coal samples, in a rectangular shape or a cylindrical shape, is burned to constant weight in a muffle furnace at 815 ℃ plus or minus 10 ℃, and then is quickly cooled to room temperature and weighed so as to calculate ash content. At present, the mainstream is cooled to two types, namely, the high Wen Huimin is placed on an asbestos net or a fireproof plate and is kept stand in the air for cooling, the mode is simple and reliable, but the cooling speed is slow, the time is twenty to thirty minutes, in addition, a cupel is immersed into water for cooling, when the cupel burns, in order to enable coal to be fully combusted, the coal is in an open state, moisture is generated in a tube after the cupel contacts with water, and the subsequent weighing weight accuracy is reduced. In addition, placing the ceramic cupel above 800 ℃ directly in a strong cold environment (such as water cooling or strong wind) can cause damage to the cupel due to instantaneous huge thermal stress, and general cooling equipment fails to fully consider the standard shape (such as cylindrical) of the cupel and the circulation requirements of the cupel in continuous and batch operation, so that a safe, efficient and automatic cooling process is difficult to realize.
