The coking fine coal coalification detection and analysis device according to claim 7, characterized in that, Also includes: The weighing module is used to receive the weighing information of the crucible weighed by the electronic balance (22) and identify the number of the crucible, generate the number information, and also used to receive the weighing information of the condensed water weighed by the weighing device (28); wherein the weighing information of the crucible includes the rated weight of the crucible, the weight of the coal sample crucible, and the weight of the dried coal sample crucible, and the weighing information of the condensed water includes the weight of the condensed water; the number information is used to trigger the weighing module to send the number to the processor and obtain the rated weight, the weight of the coal sample crucible, and the weight of the dried coal sample crucible of the crucible corresponding to the number, and generate a weight signal; the weight signal is used to trigger the weighing module to subtract the weight of the coal sample crucible from the rated weight of the crucible to obtain the net weight of the coal sample, and mark the net weight of the coal sample and the number as the initial measurement data of the coal sample; the weight signal is also used to trigger the weighing module to subtract the weight of the dried coal sample crucible from the weight of the coal sample crucible to obtain the lost net weight of the coal sample, and mark the lost net weight of the coal sample and the number as the termination measurement data of the coal sample; the weight signal is also used to trigger the weighing module to calculate the total weight of the coal sample by summing up the weights of all the coal sample crucibles, and mark the total weight of the coal sample and the weight of the condensed water as the total measurement data of the coal sample; the initial measurement data of the coal sample, the termination measurement data, and the total measurement data are fed back to the processor; The processor is used to receive the initial measurement data, the termination measurement data, and the total measurement data of the coal sample, obtain the net weight of the coal sample corresponding to the number, and normalize the lost net weight of the coal sample to obtain its value; the value is subjected to conventional moisture analysis to obtain the conventional moisture value; the net weight of the coal sample, the lost net weight of the coal sample, the total weight of the coal sample, and the weight of the condensed water are normalized to obtain the values of the four; the four values are subjected to moisture analysis to obtain the moisture comprehensive value, which is sent to the display module and the storage module; The display module is used to receive and display the conventional moisture value and the moisture comprehensive value; The storage module is used to receive and store the weighing information of the coal sample, the conventional moisture value, and the moisture comprehensive value.

9. The coking fine coal coalification detection and analysis device according to claim 8, characterized in that, It also includes a coal water analysis module; the coal water analysis module is used to obtain all the conventional moisture values, count all the conventional moisture values and generate a list, take the maximum two values and the minimum two values of the conventional moisture values in the list, respectively calculate the mean values and then calculate the difference values to obtain the deviation values; the deviation values and the moisture comprehensive values are normalized to obtain the values of the two; the values of the two are calculated to obtain the deviation value; which is sent to the display module and displayed.
