Description
Technical field
The invention belongs to coal sample division technical fields, and in particular to one kind is in coal sample making course to coal sample
Carry out the reciprocating swing reduction device of division processing.
Background technology
The quality of analytical industry coal quality, need to be through " acquisition, sample preparation, chemical examination " three processes of coal；The process of sample preparation
It is the sample for requiring to be fabricated to certain specification according to national standard chemical examination by the coal sample that acquisition comes.In sample making course, need to coal sample
Progress division processing (division is to leave and take the process of representational low-volume samples in proportion from the sample of big quantity), and this
Step generally use machinery reduction device is realized.
The operation principle of mechanical reduction device is：If a part or stem portion are taken out from sample in a manner of cutting sample.
Bias caused by it can be reduced by artificial means.National standard to " mechanical division method ", " cutter and cutting sample quality ", " cut
Cut interval ", " cutting times ", " minimum mass of sample after division " etc. have regulation；Examination " reduction device " final quality is
Whether the sample seen after its division meets the requirement of above-mentioned " national standard ".
The country has occurred various forms of " reduction devices " at present, but its division effect is undesirable:1. " rotary-type division
Device "：Fig. 1 is rotary conic reduction device schematic diagram, and operation principle is that coal is wandered on a rotating cone, then with cover by one
Adjustable opening enters receiver, and rotating cone often rotates a circle, and collects a part of sample.The inclined tube infundibulate reduction device that Fig. 2 is shows
Be intended to, operation principle be coal stream enter tipping bucket and from inclined tube be discharged, rotation inclined tube outlet running track on there are one or
Multiple fixed cutters, inclined tube outlet is often primary by cutter, that is, intercepts one " cutting sample ".Either taper or oblique
Pipe infundibulate all there is a problem that it is same, mechanical structure and control it is relative complex, division ratio adjustable range it is small (<50%),
Sample accommodation is small, so that the weight range of sample is limited to, the shadow of speed and sample flow through path length slit
It rings, easily causes moisture loss.Fig. 3 is cutting groove profile reduction device schematic diagram, and operation principle is that cutting groove passes through coal stream tunneling boring
And a part of sample is intercepted from coal stream, the coal that cutter does not intercept flows through hang plate exclusion and discards, and the reduction device is because of splicing
Bucket be movement can not be hermetically sealed, splicing and blanking are also easy to produce material leakage and airborne dust, Gu there is size segregation in it.Fig. 4 is to open
Slot banding pattern reduction device schematic diagram, operation principle are that several otch are equidistantly dispersed on an annulus, and flanged pin on slot works as belt
I.e. cutting coal stream samples when rotation makes slot pass through mouth under feeder channel, and coal sample enters container through skewed slot, falls in belt unslotted section
Coal is discarded with belt outflow.Fig. 5 is chain bucket type reduction device schematic diagram, and operation principle is that a chain type mechanically carries several buckets,
Bucket struggles against cutting dropping coal stream and extracts sample, then turn over to equidistantly distribute and with pre-set time cycle one-way movement
Coal sample under unloading.Fluting banding pattern reduction device is belt composition, and chain bucket type reduction device is that chain adds bucket structure, and volume is very huge,
It is less susceptible to seal.In conclusion there are above-mentioned variety of problems in existing reduction device, affect by the bias of division sample,
So that the actual effect of finished industrial product and bad, generally can not meet national standard.
