The utility model has the advantages that the utility model is by, at the structure for having certain slope, edge for deck design after material blanking
Cover board glide at certain gradient, due to the constant rotation of mill, material is uniformly distributed under the influence of centrifugal force
Space is ground, when the material for having bonding or the case where accumulate, scraper plate can blow the material of accumulation, blocking off in time, thus
It avoids material accumulation and disperses non-uniform situation, improve the stability and grinding end properties of mill running.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the vertical slag mill of the utility model embodiment；
Fig. 2 is the scheme of installation of the scraper plate of the utility model embodiment.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, the present embodiment is with the utility model
Implemented under premised on technical solution, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With novel range.
As shown in Fig. 1 to 2, the utility model embodiment provides a kind of vertical slag mill, which includes shell in one
Body 1, the interior top of middle shell 1 are equipped with feeder pipe 2, mill 3 and grinding roller 4 are equipped in the interior lower section of middle shell 1, with phase in the prior art
Together, the indent cooperated with grinding roller 4 is equipped in the upside of mill 3, grinding roller 4 is inclined at the top of indent, mill 3 and grinding roller 4
Between form grinding space, the downside of mill 3 connect with driving part, and the driving part band rotation of movable grinding disc 3, grinding roller 4 is fixed to be set
It sets in middle shell 1, so that mill 3 and grinding roller 4 be made to generate relative motion, and then realizes grinding.It is set on the upside of the middle part of mill 3
There is a cover board 5, the tapered shape of cover board 5 of the utility model embodiment, and feeder pipe 2 is arranged in the surface of cover board 5.In this way,
After material is fallen from feeder pipe 2, the middle part of cover board 5 is fallen in, under the action of the inclination angle of cover board 5 and its under the action of centrifugal force,
So that material enters from cover board 5 in grinding space.Through testing, when the cone angle of cover board 5 is 12 to 20 °, having preferably is prevented
In the effect that the middle part of cover board 5 accumulates.Improved component is not directed to for other the utility model and structure repeats no more.
In order to further prevent material to accumulate on cover board 5, several scraper plates 6 are additionally provided in the top of cover board 5, scraper plate 6
Upper angle of declination is identical as the cone angle of cover board 5, i.e., scraper plate 6 is disposed in parallel with cover board 5, so that 6 scraper of scraper plate is uniform, scraper plate 6
It is equipped with gap with the upper side of cover board 5, while scraper plate 6 realizes scraper, friction will not be directly generated with cover board 5.Scraper plate 6 with
Gap between cover board 5 is the partial size of 20mm to 40mm, preferably 30mm, about 3 times of maximum materials.
In order to improve scraper effect, the scraper plate 6 of the utility model embodiment is preferably provided to arc shape, and the arc of scraper plate
Opening direction is arranged towards 3 rotation direction of mill.Scraper plate 6 can be 3 to 6, preferably 4, can be adjusted according to actual needs
It is whole.Scraper plate 6, so that the material entered in grinding space is evenly distributed, is conducive to grinding preferably by being uniformly arranged.As scraper plate 6
Preferred mounting means, the inner end of scraper plate 6 is mutually permanently connected, is preferably welded together, by the middle part of each scraper plate 6
It is connected to the lower end of a blade holder 7, the upper end of each blade holder 7 is connected on a blade holder crossbeam 8, blade holder is horizontal
One end of beam 8 is fixed on the inside of middle shell 1, and 8 other end of blade holder crossbeam is fixed on the blade holder crossbeam 8 with its interconnection
Middle part installs not only stable structure in this way, forms the installation space of grinding roller 4 between two adjacent blade holder crossbeams 8 with regard to being spaced
10, the installation of grinding roller 4 is not interfered, a rectangular space 11 is enclosed among 4 blade holder crossbeams 8, does not interfere blanking, and be convenient for
Rebuilding construction is carried out in existing equipment.For the ease of overhauling and installing, scraper plate 6, blade holder 7, blade holder crossbeam 8 and middle shell
Connection between 1 is preferably connected by screw bolts.5 side-impact of cover board is impaired in order to prevent, and protective layer is equipped on the upside of cover board 5
