Description
Technical field
The present invention relates to roller mill separator accessories fields, especially disclose a kind of roller mill separator efficiency test sampling
Device.
Background technique
Material grinding screening technique passes through the development of many years, and third generation powder concentrator has been obtained for being widely applied.It leads
Eddy flow is generated using rotor rotation, when wind, which carries material, passes through eddy flow region, material is in centrifugal force, wind tractive force and gravity
Under effect, the screening of different-grain diameter material is carried out.The lesser qualified partial size material of those centrifugal force then under the draw of wind,
It is brought to outside powder concentrator, is collected with dust-precipitator, and the biggish off grade size material of those centrifugal force is then under self gravity,
Again mill is fallen back, again grinding.It simultaneously can be big by centrifugal force to control material particles according to the size of rotor speed
It is small, thus the material particles of specification required for adjusting.
Existing third generation powder concentrator pattern is more, and the powder concentrator effect of each pattern is also not quite similar.Due to operating condition
Difference is difficult to be compared powder concentrator from yield and product quality, and powder concentrator efficiency needs to use and enters powder concentrator
Material gradation before stator blade is calculated.Since roller mill separator is a closed circulating system, material enters choosing
Negative pressure reaches -8000pa at powder machine stator blade, and lacking a kind of effective tool now can be from roller mill separator by material and wind
It takes out after separating, also the actual grinding efficiency of roller mill separator can not just be calculated.
Summary of the invention
This patent is to solve existing roller mill separator actual operating efficiency due to can not take out material inside powder concentrator
Unmeasured problem, the invention discloses a kind of roller mill separator efficiency test samplers.
This patent is adopted the technical scheme that solve technical problem present in well-known technique:

Side of the plate far from handle it is parallel be equipped with little particle stock supporting plate；Pass through vertically between the little particle stock supporting plate and inlet plate
Connecting plate is connected as one；The top of the inlet plate and little particle stock supporting plate is equipped with top plate；Little particle stock supporting plate is far from charging
Vertical removable filter net is equipped between one end and top plate of plate；Inlet plate corresponds to be equipped between one end of handle and top plate after
Side plate offers circular hole on back side panel；The drainage conduit of circular hole described in face is also welded on the outside of back side panel；The drainage conduit and institute
State handle threads connection；Remaining position in sampling storehouse is blocked closed by steel plate.
Further, the rectangular or rounded taper body of upper and lower opening is equipped in the sampling storehouse at face feed inlet.
Further, the top plate includes the straight panel parallel with little particle stock supporting plate and the arc plate that is located above inlet plate；
The straight panel and arc plate are integrally formed.
Further, the straight panel end is welded with exit plate；The filter screen is located between cover board and exit plate.
This patent has the advantages and positive effects of:
1. the present invention cooperates egress filtering net using being connected to feed inlet by changing to the small makeup of the imports greatly,
While capable of separating wind and material in powder concentrator, material is retained in sampling storehouse, material does not leak outside, and sampling is accurate.
2. offering drainage conduit on rear side of sampler of the present invention, handle need to only be backed out after sampling, it can be by material from discharge
Pipe is poured out, compact-sized, and sampling efficiency is high.
3. the configuration of the present invention is simple can be realized in powder concentrator without extra power auxiliary and sample, easy to operate, it is suitble to push away
Extensively.
