Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 and figure 2 As shown, the vertical rotary coal sample rapid dehumidification device with moisture dynamic detection of the present invention includes a cabinet 1, a vertical rotation mechanism 4, a controller 2, more than one heater 3 and a dynamic moisture detection component. The chamber is the dehumidification chamber 101, the heater 3 is installed in the dehumidification chamber 101 and connected with the controller 2, and is used to increase the temperature in the dehumidification chamber 101, so as to dehumidify the coal sample 5, and the controller 2 uses To control the work of the heater 3. The vertical rotation mechanism 4 includes a drive transmission assembly and a sample disk rotation shaft 401 located in the dehumidification chamber 101. The sample disk rotation shaft 401 is arranged along the ...

Abstract

The invention discloses a vertical rotation-type coal sample rapid dehumidification device having a dynamic moisture detection function. The vertical rotation-type coal sample rapid dehumidification device having a dynamic moisture detection function comprises a case, a vertical rotary mechanism, a controller and a heater. An inner cavity of the case is a dehumidification chamber. The heater is installed in the dehumidification chamber. One or more sample disc suspension arms are arranged on a sample disc rotary shaft of the vertical rotary mechanism along a peripheral direction; a sample disc is connected to a lower part of each one of the one or more sample disc suspension arms; and a material tray for receiving a coal sample is arranged on each one of the sample discs. One end of a sample weighing rod of a dynamic moisture detection assembly is connected to a sample weighing balance and the other end is located below any position in a sample disc rotation travel; and the sample weighing balance is connected to a sample weighing lifting driving mechanism and is lifted and dropped by the sample weighing lifting driving mechanism. The controller determines dynamic moisture of a coal sample according to a weight signal acquired by the sample weighing balance and transmits a control signal to the heater. The vertical rotation-type coal sample rapid dehumidification device having a dynamic moisture detection function has the advantages of simple structure, convenient operation, good heating uniformity, high dehumidification efficiency, low energy consumption and high sample preparation accuracy.

Description

technical field [0001] The invention mainly relates to the field of coal sample preparation equipment, in particular to a vertically 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 an inhomogeneous substance (grain 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), so as to maximize the sample that can represent the quality and characteristics of the entire stock sample 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 ...
