Abstract

The invention discloses an automatic total moisture tester for a coal sample, which comprises a frame by transverse arrangement, a sample introduction and weighting apparatus as well as a sample sending and weighting apparatus are respectively provided at two ends of the frame, a drying apparatus is provided between the two apparatuses, a sample introduction apparatus and a sample sending apparatus are respectively provided on the sample introduction and weighting apparatus and the sample sending and weighting apparatus, and a coal sample transmission apparatus connected to the sample introduction apparatus and the sample sending apparatus are provided at the lower part of the drying apparatus. According to the invention, a whole process for testing the coal sample total moisture which is realized through an automatic control system is automatically controlled by a computer, the total moisture result can be automatically calculated, and a technical bottleneck problem in a network automation coal quality management system can be solved simultaneously, and the automatic total moisture tester for the coal sample has the advantages of time saving, labor saving, and high accuracy and efficiency.

Description

technical field [0001] The invention belongs to coal sample total moisture testing equipment, in particular to an automatic coal sample total moisture tester. Background technique [0002] At present, the method of testing the total water content of coal samples is to use the oven drying method to test the total water; use a metal sample pan that can hold 1000g-2000g coal samples, put about 1000g (particle size 6mm) of coal samples, and put them in an oven at 110°C , bake for 2 hours, take out the difference between weighing and baking to calculate the total moisture content. In this method, each process and calculation need to be manually operated, which is slow, takes a long time, and has low work efficiency. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a high degree of automation, time-saving, labor-saving, accurate, efficient coal sample automatic full mois...
