It rises to powder selection device and carries out finished product screening, reduce improving material amount and screening plant treating capacity, to reduce lifting device
With the installed power of screening plant, also reduces the installed power of blower needed for screening plant indirectly, reached energy-saving consumption-reducing
Purpose.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The embodiment of invention for those of ordinary skill in the art without creative efforts, can also basis
The attached drawing of offer obtains other attached drawings.
Fig. 1 is the structural schematic diagram of three-level screening scraper of the present invention；
Fig. 2 is the partial enlargement structural representation in Fig. 1.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, to the technical solution in the prior art and the embodiment of the present invention into
Row clearly and completely describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
Every other embodiment, shall fall within the protection scope of the present invention.
With reference to the accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Referring to Figures 1 and 2, the preferred embodiment of the present invention provides a kind of three-level screening scraper dress suitable for outer circulation Vertical Mill
It sets, including vertical mill casing 1 and mill 2, the space between vertical mill casing 1 and mill 2 are set as lower material space, this blanking space interior
It is successively arranged level-one sieve 3 and second level sieve 4 from top to bottom, this level-one sieve 3 and second level sieve 4 separate the lower material space
For material space under material space under material space, second level under the level-one that is arranged successively from top to bottom and three-level, material space under the level-one,
Be respectively equipped in material space under material space and three-level under second level be fixedly connected with mill material scraping plate (respectively the first material scraping plate 5,
Second material scraping plate 6 and third material scraping plate 7), be additionally provided on vertical mill casing 1 respectively with material space under material space, second level under level-one and
Coarse powder feed opening 8, middle coarse powder feed opening 9 and the fine powder feed opening 10 that material space is connected under three-level.
The screening precision of the level-one sieve 3 is lower than the screening precision of second level sieve 4, and specific screening precision can be according to technique
System requirements is accordingly set.
The sealing structure for material and mill to be isolated is equipped between the material scraping plate and mill.
