Example Embodiment

[0022] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as Figure 1-Figure 3 As shown, an air-saving protective gas drying box provided by an embodiment of the present invention includes a plurality of drying chambers 101, a main intake pipe 103, a main exhaust pipe 104, and a control unit. The gas passages of the multiple drying chambers 101 are connected in series. The ...

Abstract

The invention relates to the technical field of a coal sample detecting device, in particular to a gas-saving type protective gas drying box. The gas-saving type protective gas drying box comprises a plurality of drying cavities, a main air inlet pipe, a main exhaust pipe and a control unit. Gas channels of the plurality of drying cavities are arranged in series. The main air inlet pipe is used for pumping protective gas into the plurality of drying cavities and the protective gas after use is discharged through the main exhaust pipe. A heating component is arranged in each drying cavity. The control unit is used for controlling the heating speed of each heating component and the on-off of the main air inlet pipe. According to the gas-saving type protective gas drying box provided by the invention, the repeated usage of the protective gas can be realized, the usage amount of the protective gas can be greatly saved, the cost can be saved and the labour intensity of the operating personnel can be reduced. The protective gas carries a part of heat when getting into one drying cavity from another drying cavity, so that a preheating effect can be played and the warming time of the drying cavity where the protective gas enters is shortened. Accordingly, the electric energy consumption can be reduced and the cost can be further saved.

Description

technical field [0001] The invention relates to the technical field of coal sample detection devices, in particular to a gas-saving protective gas drying box. Background technique [0002] The chemical composition of coal is composed of organic hydrocarbons and inorganic substances, and the moisture in coal is the most likely to change component. Coal moisture is the most basic index to evaluate the economic value of coal, because changes in coal moisture will cause changes in the content or calorific value of other components, which will have a certain impact on coal quality inspection, measurement, acceptance, management, etc. At the same time, when there is a large amount of water in the coal, not only the useful components of the coal are reduced, but also when a large amount of water is burned, it absorbs a large amount of heat and becomes water vapor, which is evaporated in vain, and increases the amount of flue gas, increasing the loss of smoke exhaust and exhaust gas...
