Description
Technical field
The utility model relates to silicon carbide micro-powder production equipment, especially a kind of raymond mill blanking device of being convenient to material sampling.
Background technology
The Raymond mill that the utility model is used is 3R8020 type Raymond mill.Main motor model is Y225M-8 18.5KW.Raw material granularity sand enters main frame grinding chamber by feeding chamber, after grinding roller and bull ring grinding, under air-introduced machine effect, drives powder to carry out sorting through a grader that is placed in grinding chamber top.The excessively thick particle of granularity again falls within grinding chamber and returns mill, and the particle that granularity meets the specification enters No. two grader accurately sortings again, and qualified granularity group enters by a mouth ton bag being placed under it, after test package, quality inspection selective examination, checks warehouse-in.This product is a mouth material, is major product, and granularity is between GC#2000 to GC#1500.
Less particle flows to the wind into cyclone separator sorting, enters by No. two mouths the ton bag being placed under it, and this product is byproduct, after test package, quality inspection selective examination, checks warehouse-in.This product is No. two mouth material, and granularity is between GC#2500 to GC#2000.
Finally enter collector from the backwind tube of cyclone separator upper end and collect ultra-fine grain, collect and enter by No. three mouths the ton bag being placed under it in dust cleaning case, this product is also byproduct, after test package, quality inspection selective examination, checks warehouse-in.This product is No. three mouth material, and granularity is greater than GC#2500.
Raymond mill is negative pressure state in inside in the time of normal operation, and in order to ensure output and the product quality of equipment, the overall tightness of necessary guarantee equipment is good.
In prior art, feed opening all uses canvas to make movable being flexible coupling of energy, facilitates Quality Inspector to carry out sample examination to the feed opening of every grinding machine.Because poorly sealed easily smoldering caused Lou material phenomenon, cause a large amount of loss of material.Because silicon carbide micro-powder is superfine powder, therefore not complete hermetic structure causes feed opening place to have a large amount of airborne dusts, affects the environment in workshop simultaneously.Owing to sampling herein, and equipment when operation internal gas flow is negative pressure state, therefore must will get well by guarantee equipment overall tightness in the time moving, and guarantees again to sample from feed opening easily.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, sealing is tight, reliable operation, can greatly enhance productivity, the economical and practical raymond mill blanking device of being convenient to material sampling.
The utility model discloses a kind of raymond mill blanking device of being convenient to material sampling, it is characterized in that comprising totally-enclosed connecting pipe 2, described totally-enclosed connecting pipe upper end open is material receiving port 1, lower ending opening is feed opening 8, feed opening 8 places are connected with screw machine 7, in described totally-enclosed connecting pipe 2, be provided with upper strata butterfly valve 3, lower floor's butterfly valve 4, in the totally-enclosed connecting pipe 2 between described upper strata butterfly valve 3, lower floor's butterfly valve 4 and screw machine 7, be provided with sample tap 5, sample tap 5 is provided with sampling gate 6.
Described sample tap 5 is hinged by hinge 9 with sampling gate 6, and sampling gate 6 is provided with handle 11.
Between described sample tap 5 and sampling gate 6, be reliably connected by earth connection 10.
Compared with prior art, it is hermetically sealed that the utility model makes feed opening place use pipe to carry out, and the sampling gate of making energy switch on steel pipe carries out sample examination, and while sampling at ordinary times, door keeps closed condition, the sealing of guarantee system is opened door and is sampled in the time that needs sample.In order to ensure that door is reliably connected with equipment, use earth connection opposite house to be reliably connected (raymond grinding powder machine equipment reliable ground) with pipe.When making, must ensure that sampling gate system sealing in the time closing is functional, in the time that needs sample, can be easy to open again.The utility model has reduced the airborne dust at loss of material and feed opening place, has improved the integrated environment in workshop.
The utility model is rational in infrastructure, sealing is tight, reliable operation, can greatly enhance productivity, and is a kind of economical and practical raymond mill blanking device of being convenient to material sampling.
