Description
Technical field
The utility model is related to coking of coal fields, are related to a kind of grind away screening plant, aobvious more particularly to a kind of coal petrography
The grind away of micro mirror coal sample sieves all-in-one machine.
Background technology
As coking is reduced increasingly with high-quality coal resource, each coal chemical enterprise has to use other more and more coals,
In order to obtain the profit of great number, some coal washerys are sold good coking coal is regarded after two kinds either a variety of coal washing mixing washings
To coal chemical enterprise, and the routine inspection method of coking enterprise cannot effectively identify mixed coal situation, can not detect various coals
Mixed ratio is how many.In addition, various regions coal resource is diversified, even the Coal Quality of identical type be also it is irregular not
Together, cause the quality for the single grade coal that coal chemical enterprise uses that cannot effectively ensure in this case.These doping mixed coals and
Coal-blending coking is carried out as raw material as single grade coal by coal chemical enterprise, the coke quality produced hardly results in guarantee so that
Follow-up ironmaking, STEELMAKING PRODUCTION are greatly affected.Start to use coal petrography theory for this situation coal chemical enterprise, with microscope
For main tool, single grade coal and Mixture Density Networks are differentiated by the maximum reflectance of vitrinite of coal, simultaneously also pass through reflectivity point
Butut effectively identifies mixed coal ratio, and the development of especially automatic coal petrography vitrinite detection technique substantially reduces coal petrography detection
Time, to examine, differentiating that mixed coal provides effective technological means soon into factory's coal, in recent years, coal petrography coal separation, Coal Blending Technology are more next
It is more paid close attention to by each R＆D institution and manufacturing enterprise, the quality of raw material clean fine coal is controlled with coal petrology parameter,
It instructs coal chemical enterprise coal-blending coking to produce, improves coke quality, production cost is made effectively to be reduced.
Coal petrology analysis needs to prepare lump coal mating plate, and representative division sample is typically crushed to defined 1mm
Following granularity, and the coal sample quality less than 0.1mm is no more than 10%, mixes and is consolidated into binder by a certain percentage after dry
Then forming blocks carry out sand paper grind away, polishing treatment to forming blocks.Currently, in auxiliary breaking and being sized to 0.1mm~1mm
When the coal sample of degree, after mainly grinding coal sample carefully using manual mortar, then the sample of 1mm, 0.1mm grain size is used to be sieved
Point, in order to ensure the representativeness of sample, granularity after sieving is needed to continue to grind more than coal sample on 1mm sieves, until grain size is whole
It is mixed less than 1mm, and then with binder, consolidation is blocking.Hand lapping in this way-screening-is ground again-is sieved again (if granularity is still big
Need to repeat aforesaid operations in 1mm, until granularity is all less than 1mm, wherein be no more than less than 0.1mm it is 10%) cumbersome and time consuming,
It largely hinders in production and carrys out coal sample coal petrography detection rates.
In previous coal petrography grind away screening machinery, the grinding of coal petrography microscope coal sample is not related to, is sieved while is continuous
The device of operation.It is main just like a kind of preparation method of coal petrography fine coal mating plate of patent (105400139 A of CN) by patent retrieval
Coal petrography mating plate preparation method is described, includes the mixed proportion with binder, heating temperature, forming temperature and soaking time
Deng being not directed to the grinding and screening of coal sample.Also mainly it is situated between just like a kind of coal petrography sample grinding machine of patent (104977204 A of CN)
It has continued and has been bonded to the grind away device of pattern, what is be related to is also molding mating plate grind away.In addition, for other solid samples it is broken/
Crushing, screening machine are retrieved, such as patent solid grinding bolting mill (205109756 U of CN), the sieve which is related to
Divide cylinder to be only capable of carrying out Monosized powder rank screening, coal petrography sample preparation can not be met and wanted between two particle size fractions of 0.1mm~1mm
It asks, and coal sample is on the rotating percussion to screening bore of blade, it is easy to cause screening hole plug, the sifting barrel in shell is simultaneously
It is not easy to replace.Also just like a kind of pigment production grinding bolting mill of patent (205288521 U of CN), although the utility model powder
Broken, screening can be carried out at the same time, but carried out roll shaft attrition crushing sample and be mainly suitable for the larger blocky sample of granularity, and granularity is wanted
It asks and is crushed in 0.1mm~1mm coal petrography coal samples more difficult to control, which finally obtains sample granularity and be minimum particle size or cry side
Edge granularity can not realize some intermediate stage sizing.Compression roller, runner, crushing tooth in device, carry vibrating motor
It is power consumption device to rise mechanical, electrical magnetic suck, exhaust fan etc., for a small amount of sample needed for a variety of coal samples, the detection of multiple discontinuity coal petrography
Producing for product is not appropriate for.
