Self-driven disc rotor for Raymond mill

Article source:admin Popularity:Dateline:2018-11-14 16:46

The invention relates to the field of Raymond mill powder sorting equipment, and particularly relates to a Raymond mill sorting machine which adopts self-driven permanent magnet rotor direct driving, high powder selection rate, good energy saving and emission reduction effect, and precise control of fineness of powder selection. Self-drive disc rotor.
 
At present, the disc rotor of the Raymond mill is equipped with an external motor to drive the central shaft through a pulley, a reducer, etc., thereby rotating the disc rotor on the central shaft for powder selection. Due to the mechanical transmission part such as reducer, there is energy loss, the transmission efficiency is also low, and the fineness of powder selection is uncontrollable.
 
The purpose of the utility model is to overcome the problem that the external motor used in the conventional disk rotor drives the central shaft to rotate, and the powder is lost due to mechanical transmission, and the transmission efficiency is low, and a reasonable structure is adopted. The self-driven disc rotor for the Raymond mill separator is driven by the direct drive of the permanent magnet rotor, the energy saving and emission reduction effect is good, the powder selection rate is high, and the fineness of the powder selection can be precisely controlled.
 
Technical solutions:
 
A self-driven disc rotor for a Raymond mill classifier, comprising a classifier housing and a powder selection rib plate located inside the class of the classifier, the casing of the classifier further comprising a vertically arranged wheel hub The hub is a cylindrical tubular structure and a horizontal convex plate is disposed on the outer circumference of the hub, the horizontal convex plate surrounds the hub and is disposed perpendicular to the hub, and the horizontal convex plate is provided with an annular leaf disc, and the bottom of the leaf disc is evenly arranged. There is a set of blades, the inner end of the blade is close to the end of the horizontal convex plate, the inner wall of the hub is provided with a uniform set of permanent magnets, and the permanent magnet is disposed vertically with the inner wall of the hub, and the inside of the hub is also provided with a central fixed shaft, the central fixed shaft is coaxially disposed with the hub, the stator winding is disposed outside the circumference of the central fixed shaft, and the stator winding and the permanent magnet are non-contact; the top end of the hub is provided with an upper cover, an upper cover and An upper bearing is disposed between the central fixed shafts, a lower cover is disposed at a bottom end of the hub, and a lower bearing is disposed between the lower cover and the central fixed shaft.
 
A stator winding threading hole is disposed in the center fixed shaft, and one end of the stator winding threading hole is located at the center of the bottom end of the center fixed shaft, and the other end is located on the inner side wall of the center fixed shaft. A gland is disposed above the upper cover, and a top end of the central fixed shaft passes through the upper cover under the gland, and a bottom end of the central fixed shaft passes through the lower cover and penetrates the varietal plate, and is located at the center of the inside of the variet plate A fixed sleeve is arranged on the fixed shaft, and a nut is arranged at the bottom end of the central fixed shaft. The horizontal convex plate is provided with a vertically distributed through hole in the vertical direction, and a bolt is arranged in the through hole to fix the leaf disk.
 
The blade is fixed on the blade disc by bolts, and the bottom of the blade is further provided with a first pressing ring and a second pressing ring, wherein the first pressing ring and the second pressing ring are concentrically arranged annular gaskets, and the radius of the first pressing ring is larger than the first ring The radius of the two pressure rings, the bolts respectively penetrate the first pressure ring, the second pressure ring and the blades and the leaf discs, and fix the blades and the leaf discs together. The blade is a plate-like structure of a right-angled trapezoidal shape.
 
The positive effect of the utility model is: the self-driven disc rotor for the Raymond mill powder sorting machine provided by the utility model. It is a permanent disk rotor with blades. The rotor rotates around a fixed axis. The fixed shaft has DC or AC stator windings. When the windings are energized, a magnetic field can be generated. The permanent magnet receives the magnetic field and can drive the entire rotor to rotate. The self-driven permanent magnet rotor direct drive is more than 5% efficient compared with the traditional motor driven by mechanical transmission, and the energy saving and emission reduction effect is good; the self-driven rotor, no mechanical transmission part, high reliability; using self-driven rotor, Precise control of rotor speed for precise control of selected dust fineness.
