Description

One kind sealing pocket type coal sample mixing arrangement

Technical field

The utility model category is related to a kind of sealing pocket type coal sample mixing arrangement, is mainly used in the mixing of coal sample, and category material mixes Close technical field.

Background technology

Coal is a kind of complicated, inhomogenous mixture of composition, therefore before coal qualities test, need to be fully mixed by coal sample Close, such as GB/T 211-2007《Total moisture determination method in coal》It is middle regulation " before weighing coal sample, should be by the coal sample in sealing container It is mixed thoroughly for a minimum 1min ".It is difficult under many circumstances however, this seems shirtsleeve operation, its reason is： （1）Gimmick is improper causes coal sample size to isolate on the contrary for lab technician's mixing；（2）When larger amount of coal sample needs mixing, artificial behaviour Make more difficulty, if the full aquametry minimum intakes of 13mm and 6mm are respectively 3kg and 1.25kg；（3）Incorporation time deficiency 1min；（4）To ensure testing result accuracy and avoiding sample from polluting, it is impossible to which coal sample to be transferred in other mixing arrangements or make Mixed with stirring rod, be mixed the phenomenon of edge generation coal sample size isolation using stirring rod in addition.

At present, commonly using sealing pocket type coal sample minimum intake has tetra- kinds of 3kg, 1.25kg, 0.65kg and 0.1kg, existing Coal sample mixing arrangement, few suitable for the mixing of pocket type coal sample or in the presence of the problems such as not reasonable is designed, majority is using manual Formula mixes, it is necessary to is improved design.
