The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-3, a scraper device, including scraper blade 1, scraper blade 1 top spiro union has base 2, install this device on the vertical mill well through base 2, the cross-section of scraper blade 1 is the arc structure, it is concrete, the arc structure is left and right sides forward protruding, the arc structure of mid portion backward protruding, in use, the concave surface orientation of scraper blade 1 deviates from mill pivoted direction, make and reserve the clearance that meets the requirements between scraper blade 1 and the mill, when the powder that glues on the mill passes through scraper blade 1, break away from the mill under scraper blade 1's the clearance effect of scraping, blow away by the air current, the orthographic projection of scraper blade 1 is big end down's isosceles trapezoid, be convenient for scraper blade 1 can scrape the mill region of clearing more large-span, and simultaneously, when the accumulational powder in front of scraper blade 1 is too much, can flow away from scraper blade 1's both sides again, and can not long-pending more, prevent that the powder from piling up.

Scraper 3 is installed to scraper 1 bottom, scraper 3 replaces scraper 1 to press close to the mill, compare in scraper 1, scraper 3's small, it is convenient to change, and the cost of use is low, scraper 3 is the arc structure with 1 laminating of scraper blade, namely scraper 3 is also the arc structure, improve scraper 1 to the laminating degree of scraper 3, be convenient for fixed scraper 3, the width value of scraper 3 is less than the width value of scraper 1's bottom, scraper 3 installs the one end in scraper 1 bottom, it is specific, install the one end that is close to the mill edge at scraper blade 1, make scraper 3 be located the grinding zone of grinding roll, make scraper 3 can accurately scrape the powder on the clearance mill, and leave great clearance between the one end of mill edge and the mill in scraper 1 bottom, a material for leveling the mill center, prevent material thickness inhomogeneous, influence grinding, scraper 3 comprises a plurality of closely arranged blades, the blade spiro union is fixed on scraper 1, when blade wearing and tearing are inhomogeneous, can change serious blade alone, when blade wearing and tearing are even, it can to carry out the whole change, thereby save the use cost of scraper 3, scraper 3 is for the scraper is the scraper closely arranged blade, the scraper, the high frequency of hard alloy further reduction of the frequency, thereby the service life of the extension reduces, the hardness of the scraper is further reduced, the service life of hard alloy.

The welding of 2 tops of base has mount 4, installs this device on immediately grinding a well section of thick bamboo through mount 4, offers the long circular slot that is used for adjusting 1 horizontal position of scraper blade on the mount 4, and the long circular slot is interior for fixing bolt, and 4 spiro unions of mount are fixed on immediately grinding a well section of thick bamboo, finely tune this device position in the quotation of mill through the long circular slot, reduce the installation degree of difficulty.

The spiro union has fixed plate 5 on the mount 4, offers the long circular slot that is used for adjusting 1 vertical position of scraper blade on the fixed plate 5, and this device is used for finely tuning the clearance between the quotation of this device and mill through the long circular slot on the fixed plate 5 on the vertical mill well section of thick bamboo through the welding of fixed plate 5, is applicable to different materials, improves the application scope of this device.

Fixed plate 5 includes along the first fixed plate 51 of vertical setting, second fixed plate 52, third fixed plate 53, first fixed plate 51 is parallel with second fixed plate 52, third fixed plate 53 is perpendicular with second fixed plate 52, rectangular groove on fixed plate 5 is seted up at first fixed plate 51, second fixed plate 52, on third fixed plate 53, first fixed plate 51, second fixed plate 52, third fixed plate 53 passes through the bolt fastening of rectangular groove on mount 4, specifically, first fixed plate 51, second fixed plate 52 is parallel with the direction of rotation of mill, third fixed plate 53 is perpendicular with the direction of rotation of mill, thereby improve the reverse holding power that receives when this device scrapes the clearance powder, improve the stability of this device.

The working principle is as follows: when the device is used, the device is arranged in a middle cylinder of a vertical mill through the fixing plate 5, the concave surface of the scraping plate 1 deviates from the rotating direction of the grinding disc, the scraping plate 3 is positioned on the grinding track of the grinding roller, and the device and the grinding roller are arranged in a one-to-one quantity ratio;

when the grinding roller rolls the powder, part of the powder is adhered to the grinding area of the grinding disc, and when the powder passes through the lower part of the scraper 3, the powder is scraped and cleaned by the scraper 3 to become loose and then is blown away by the airflow in the vertical mill.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
