Description
Technical Field
The utility model relates to an electric power field specifically is a quiet ring of coal pulverizer.
Background
The nozzle ring is an important part of the medium-speed coal mill and directly influences the ventilation resistance of the medium-speed coal mill and the discharge amount of pebble coal of the coal mill. The resistance change at the nozzle ring is complex and is related to the load of the mill, the temperature of hot air, the granularity of raw coal, the grinding air inlet quantity and the like. The static ring and the movable ring of the coal mill jointly form the most rotational structure, the static ring is fixed on a cylinder body of the coal mill, and the movable ring and the static ring move relatively, so that the static ring is inevitably abraded, and a scheme for solving the abrasion problem of the static ring is needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a quiet ring of coal pulverizer.
The technical scheme of the utility model is that: quiet ring of coal pulverizer, including coal pulverizer section of thick bamboo wall, be equipped with quiet ring on the coal pulverizer section of thick bamboo wall, quiet ring top is equipped with decurrent platform, the platform side is equipped with the ring that keeps out the wind, the quiet ring outside of ring below that keeps out the wind is equipped with the antifriction plate, stopper and quiet ring joint are passed through to antifriction plate below one side, the antifriction plate top is passed through the bolt and is linked to each other with quiet ring, the antifriction plate includes the bottom antifriction plate, replacement antifriction plate and top layer antifriction plate, the bottom antifriction plate, replacement antifriction plate and top layer antifriction plate connect gradually, the stopper that bottom antifriction plate lower part cambered surface back was equipped with and quiet ring joint was used, replacement antifriction plate lower part cambered surface back one side is equipped with the fixture block, the cambered.
Further, the wind blocking ring is provided with a downward inclination angle, and the angle between the inclination angle and the platform is 135-165 degrees.
Further, the bolt is located below the wear surface.
Further, the one end of bottom antifriction plate, replacement antifriction plate and top layer antifriction plate all is equipped with the bolt hole, and the replacement antifriction plate is equipped with a plurality of.
The utility model discloses an useful part: the utility model discloses simple structure can carry out the increase and decrease of antifriction plate through carrying out joint etc. to the antifriction plate, effectively improves the use matching degree of quiet ring.

Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in figure 1, the static ring of the coal mill comprises a coal mill cylinder wall 1, a static ring 2 is arranged on the coal mill cylinder wall 1, a downward platform 7 is arranged at the top of the static ring 2, a wind blocking ring 6 is arranged on the side surface of the platform 7, the wind blocking ring is provided with a downward inclination angle, the angle between the inclination angle and the platform is 135-165 degrees, a wear-resisting plate 3 is arranged on the outer side of the static ring 2 below the wind blocking ring 6, one side below the wear-resisting plate 3 is clamped with the static ring 2 through a limiting block 4, the upper side of the wear-resisting plate 3 is connected with the static ring 2 through a bolt 5, the bolt is positioned below a wear-resisting surface, the wear-resisting plate 3 comprises a bottom wear-resisting plate 31, a replacing wear-resisting plate 32 and a surface wear-resisting plate 33, the bottom wear-resisting plate, the replacing wear-resisting plate and the surface wear-resisting, the fixture block 34 is arranged on one side of the back face of the cambered surface at the lower part of the replacement wear-resisting plate, the cambered surface is provided with a groove matched with the fixture block 34, the fixture block is arranged on one side of the lower part of the back face of the cambered surface of the surface layer wear-resisting plate, and the cambered surface is a smooth cambered surface.
Through setting up bottom antifriction plate, replacement antifriction plate and top layer antifriction plate, after being worn and torn as the one deck, can carry out timely replacement, perhaps under urgent circumstances, after directly taking away the one deck of wearing and tearing, can use remaining antifriction plate, when the coal pulverizer of the different models of cooperation, can carry out appropriate increase and decrease to the antifriction plate.
