Abstract
The invention discloses an eccentric grinding roller device of a grinding mill. The eccentric grinding roller device comprises a grinding roller and a grinding roller assembly which are uniformly distributed around a spindle of the grinding mill and a grinding roller frame arranged on the spindle of the grinding mill, wherein the grinding roller is arranged in the grinding roller frame, a grinding roller shaft is divided into an upper shaft section and a lower shaft section which are coaxial and an eccentric shaft section arranged at the middle section, the eccentric shaft section and a grinding roller shaft hole are coaxially arranged in a rotary manner, the coaxial shaft sections are arranged in a shaft hole correspondingly arranged on the grinding roller frame in the rotary manner; and the axis of the coaxial shaft sections is located in radial direction at the rotary center of the spindle of the grinding mill, and the eccentric shaft section deviates from the axis of the coaxial shaft sections in a reverse direction of the rotary direction of the spindle of the grinding mill. According to the invention, the grinding roller shaft adopts an eccentric structure, and the grinding roller can deflect in the reverse direction of the rotation of the spindle of the grinding mill, so that the grinding roller can effectively avoid impact of large granular material, vibration in operation of the grinding mill is reduced, increase of rotating speed of the spindle of the grinding mill is facilitated, and further yield and efficiency are improved.
Description
(1) technical field:
The present invention relates to the powder equipment part, be specially a kind of flour mill centering type Burnisher apparatus.
(2) background technology:
Flour mill is the most widely one of equipment of powder sector application, its operation principle is: the Burnisher apparatus of flour mill is at the drive backspin of the grinding roller frame living centrifugal force of changing the line of production, under the effect of centrifugal force, grinding roller in the Burnisher apparatus interacts with roll mode and bull ring, thereby realizes rolling material.
In the traditional structure of described Burnisher apparatus, grinding roller is coaxially installed on the shaft of grinding roller, and shaft of grinding roller is installed in the radial groove of offering on the grinding roller frame, under the centrifugal action that the rotation of grinding roller frame produces, grinding roller is mobile being pressed on the bull ring radially, and both interaction partners therebetween material roll.
Roll in the process, in the situation about can't disposablely pulverize such as large granular materials, the reaction force of large granular materials bump grinding roller makes grinding roller with radially opposite direction rollback in chute, continues down to mill unclassified stores thereby dodge out large granular materials.
And the vibrations when the continuous bump between grinding roller and the large granular materials has caused flour mill work just because the vibrations of flour mill have caused the rotating speed of abrasive dust main frame to be restricted and can't to improve, and then have limited efficient and the output of flour mill.
(3) summary of the invention:
Weak point for flour mill tradition Burnisher apparatus the present invention proposes a kind of flour mill centering type Burnisher apparatus that reduces to shake, improve output.
Can realize the flour mill centering type Burnisher apparatus of above-mentioned purpose, comprise around grinding roller and the shaft of grinding roller assembly of flour mill main shaft circumference uniform distribution and be installed on grinding roller frame on the flour mill main shaft, difference is that described grinding roller is located in the grinding roller frame, described shaft of grinding roller is divided into three sections, be respectively upper and lower section concentric shaft part and the eccentric shaft part of interlude, the mode coaxial installation of the axis hole of described eccentric shaft part and grinding roller to rotate, described concentric shaft part is installed on the grinding roller frame in the corresponding axis hole of offering in the mode of rotating; The axle center of described concentric shaft part is in the flour mill main shaft rotation center radially, and the axle center of described eccentric shaft part deviates from the axle center of concentric shaft part with the opposite direction of flour mill main shaft gyration.
The rotation mounting means of described concentric shaft part and grinding roller frame axis hole has three kinds:
1, being slidingly installed for axle and hole.
2, being slidingly installed for axle and axis hole internal axle sleeve.
3, be that axle cooperates installation with the rolling of the interior rolling bearing of axis hole.
Equally, the rotation mounting means of described eccentric shaft part and grinding roller axis hole also has three kinds:
