Embodiment Construction

[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.

[0023] Such as figure 1 As shown, the horizontal rotating coal sample rapid dehumidification device with moisture dynamic detection of the present invention includes a cabinet 1, a horizontal rotating mechanism 4, a controller 2, more than one heater 3, and a moisture dynamic detection component. The chamber is the dehumidification chamber 101, and the heater 3 is installed in the dehumidification chamber 101 and connected to the controller 2 to increase the temperature in the dehumidification chamber 101 to dehumidify the coal sample 5. The controller 2 uses To control the work of the heater 3. The horizontal rotation mechanism 4 includes a drive transmission assembly and a sample disk rotating shaft 401 located in the dehumidifying chamber 101. The sample disk rotating shaft 401 is arranged along the vertical direction. The sampl...

Abstract

The invention relates to a horizontally-rotating type rapid coal sample dehumidifying device with a dynamic moisture detection function. The device comprises a case, a horizontal rotating mechanism, a controller, heaters and a dynamic moisture detection assembly. A dehumidifying chamber is arranged in the case; the heaters are mounted in the dehumidifying chamber; more than one layer of sample plates are arranged on a sample plate rotating shaft of the horizontal rotating mechanism along the axial direction; a material plate for containing the coal sample is disposed on each sample plate; a weighing movement mechanism of the dynamic moisture detection assembly is positioned below a weighing lifting platform and drives the weighing lifting platform to make up-and-down movement; a weighing portion for contacting with a weighing sensor to complete weighing is arranged on the weighing lifting platform; and the controller judges dynamic moisture of the coal sample according to weight signals acquired by the weighing sensor and sends control signals to the heaters. The horizontally-rotating type rapid coal sample dehumidifying device with the dynamic moisture detection function has the advantages of simple structure, convenience in operation, good heating uniformity, high dehumidifying efficiency, low energy consumption, capability of improving sample preparation precision and the like.

Description

Technical field [0001] The invention mainly relates to the field of coal sample preparation equipment, and particularly refers to a horizontal rotating coal sample rapid dehumidification device with moisture dynamic detection. Background technique [0002] For coal quality analysis, it is actually a process of sampling analysis. Coal is a non-uniform material (particle size, distribution of quality characteristics, etc.). The female parent sampled is generally relatively large (ranging from tens of tons to tens of thousands of tons), and it can be drawn to the greatest extent to represent the quality and characteristics of the entire female parent. The process of representative samples is called "sampling". At present, there are multiple methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling must be carried out in accordance with the standards. [0003] After the samples are collected according to the...
