Problems solved by technology

In addition, because microwaves cannot control the internal temperature of coal samples, some coal samples may be oxidized during the microwave drying process; heating and drying, heat conduction is slow, such as heating water and then conducting to coal samples, the heating efficiency is low, and the degree of dryness of heat conduction contact parts and non-contact parts Uneven, long drying time, not suitable for continuous online drying

Abstract

An embodiment of the invention discloses a coal powder drying device which comprises a rack, a conveying mechanism, a drying box, a material distributor and a material blanking machine. The conveying mechanism is arranged on the rack, the drying box is arranged on the rack and positioned above the conveying mechanism, infrared heating pipes are arranged in the drying box, the material distributor is positioned at a feeding end of the conveying mechanism, and the material blanking machine is positioned at a discharging end of the conveying mechanism. When the coal powder drying device works, coal powder is laid on the conveying mechanism through the material distributor, a laid coal layer is fed into the drying box by the conveying mechanism, the infrared heating pipes in the drying box work to dry the coal layer fed into the drying box, and the conveying mechanism feeds the coal layer after being dried into the material blanking machine after drying of the coal layer is finished. Infrared light is utilized to dry the coal layer and directly irradiates a laid material layer on a belt, the coal powder drying device is applicable to various coal samples, uniform in drying degree, extremely high in drying efficiency and capable of continuously drying the coal powder, and the problem of online drying of coal in the process of automatic sample preparation is solved.

Description

technical field [0001] The invention relates to the technical field of machinery, and more specifically, relates to a pulverized coal drying device. Background technique [0002] The automatic sample preparation of coal is the current development direction. The general coal sample is crushed, mixed, shrunk, dried, pulverized and other processes, and finally made into a general analysis test coal sample with a particle size of less than 0.2mm. The sample preparation process is divided into several stages: making 13mm sample - making 6mm sample - making 3mm sample - making 0.2mm sample. The entire sample preparation process is unmanned and completed automatically, that is, automatic sample preparation. [0003] Coal sample pulverization refers to the sample preparation process from 3mm sample to 0.2mm sample. The 0.2mm sample is in powder form, with strong adhesion, and is easily adsorbed on the surface of the powder making machine. Powder samples with high water content c...
