Problems solved by technology
However, the existing equipment has the following deficiencies: in the process of dehumidification operation, it is often necessary to monitor the temperature of the material tray and the coal sample in the material tray in real time, so as to complete the dehumidification operation efficiently, accurately and reliably
In order to realize real-time monitoring, it is generally adopted to hang the temperature sensor in the dehumidification operation chamber, but the way of hanging the sensor often leads to low detection accuracy and cannot achieve the best monitoring effect

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 , figure 2 and image 3 As shown, the telescopic temperature measuring device for coal sample dehumidification equipment of the present invention includes a temperature measuring element 7, and one end of the temperature measuring element 7 is in the movement stroke of the sample pan 10 in the coal sample dehumidification equipment and can be connected with the sample The disk 10 is in contact, and the other end of the temperature measuring element 7 is connected with an elastic return component so that the temperature measuring element 7 returns automatically. Different from the traditional temperature measurement method in which the temperature measurement device is directly suspended in the air, the temperature measurement element 7 of the present invention can directly track and contact the temperature o...

The invention discloses a telescopic temperature measuring device for coal sample dehumidification equipment, which comprises a temperature measuring element, wherein one end of the temperature measuring element is located in a motion stroke of a sample disk in the coal sample dehumidification equipment, and can be contacted with the sample disk, and the other end of the temperature measuring element is connected with an elasticity return assembly to allow the temperature measuring element to return automatically. The temperature measuring device has the advantages that the temperature measuring device is simple and compact in structure, low in cost, easy and simple to operate, high in measuring accuracy and good in practicability.
Description
technical field [0001] The invention mainly relates to the field of coal sample preparation equipment, in particular to a telescopic temperature measuring device used for coal sample dehumidification equipment. 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 ...
