Problems solved by technology

Because the oven uses a common fan, the air exchange speed is slow and the air exchange efficiency is low, so the air in the oven will be close to saturated and absorb water, so the efficiency of drying materials with high water content in the oven will be very low

Abstract

The invention discloses a hot air penetrating outer circulation type coal sample dehumidifying device. The hot air penetrating outer circulation type coal sample dehumidifying device comprises a box, a controller, a fan, a partition plate and a gas heater, wherein the fan, the partition plate and the gas heater are arranged in the closed box. The partition plate divides the box into an upper cavity and a lower cavity, the top or the side of the upper cavity is provided with an air outlet, the bottom or the side of the lower cavity is provided with an air inlet, the fan is located at the position inside the upper cavity close to the air outlet, and the gas heater is located in the lower cavity. More than one coal sample disc for accommodating coal samples is placed on the partition plate, the bottom of each coal sample disc is provided with more than one ventilation hole, and a coal sample support for collecting falling samples is arranged below the coal sample disc. The hot air penetrating outer circulation type coal sample dehumidifying device has the advantages of being simple in structure, convenient to operate, high in dehumidifying efficiency, low in energy consumption and capable of improving sample preparation accuracy and the like.

Description

technical field [0001] The invention mainly relates to the field of coal sample preparation equipment, in particular to a coal sample dehumidification equipment using hot air penetration. Background technique [0002] For coal quality analysis, it is actually a process of sampling analysis. Coal is an inhomogeneous substance (particle size, distribution of quality characteristics, etc.), and the sampled parent stock is generally relatively large (ranging from tens of tons to tens of thousands of tons), and the samples that can represent the quality and characteristics of the entire stock sample are drawn to the maximum extent. The process of sampling representative samples is called "sampling". At present, there are many methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. [0003] After the sample is collected according to the standa...
