Through setting up the doctor-bar, can prevent that raw coal from attaching to on the grinding roller, prevent effectively that the grinding roller from blocking and can not the rotation or rotation speed is low excessively, has improved the coal-grinding efficiency.
Description
Technical Field
The utility model relates to a coal pulverizer technical field specifically is a coal pulverizer grinding roller support.
Background
In present coal pulverizer, the grinding roller below is equipped with assorted roll table, and the roll table below is connected with the mill, and the moment of torsion that the mill passed through the motor transmitted rotates, and the grinding roller passes through the passive rotation of frictional force, carries out the breakage to raw coal through rolling.
However, raw coal with larger volume occasionally appears, and when the raw coal is accumulated too much, the grinding roller has the risk of being blocked, so that the grinding roller cannot rotate, and the coal grinding efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's weak point, provide a coal pulverizer grinding roller support to solve current grinding roller and block easily, lead to the problem of coal grinding inefficiency.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a coal pulverizer grinding roller support, is including the U type spare that is used for connecting the grinding roller, the grinding roller passes through axostylus axostyle rotatable coupling in the U type spare, the inboard of U type spare is close to grinding roller periphery edge and is provided with the arc wall, the doctor-bar that the slope set up is connected to the arc wall in, keep certain clearance between doctor-bar and the grinding roller, the both sides that grinding roller one end was kept away from to the U type spare are fixed with the connecting plate, be connected with the crossbeam on the connecting plate.
Preferably, the cross beam is connected with a connecting rod, the lower end of the connecting rod is connected with a motor fixing seat, the motor fixing seat is connected with a motor, the output end of the motor is connected with a first gear, the shaft rod is connected with a second gear, the first gear is meshed with the second gear, and the motor can drive the grinding roller to rotate.
Preferably, the connecting plate and the connecting rod are both provided with screw holes, and the connecting plate and the connecting rod are connected with the cross beam through bolts.
The utility model has the advantages that: through setting up the doctor-bar, can prevent that raw coal from attaching to on the grinding roller, prevent effectively that the grinding roller from blocking and can not the rotation or rotation speed is low excessively, has improved the coal-grinding efficiency.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a U-shaped member and a grinding roll;
in the figure, 1-grinding roller, 2-U-shaped part, 3-shaft rod, 4-arc groove, 5-scraping blade, 6-connecting plate, 7-beam, 8-connecting rod, 9-motor fixing seat, 10-motor, 11-first gear and 12-second gear.
Detailed Description
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.
Referring to fig. 1-2, a grinding roller bracket of a coal mill comprises a U-shaped part 2 for connecting a grinding roller 1, wherein the grinding roller 1 is rotatably connected in the U-shaped part 2 through a shaft rod 3, an arc-shaped groove 4 is formed in the inner side of the U-shaped part 2 close to the peripheral edge of the grinding roller 1, a scraping blade 5 which is obliquely arranged is connected in the arc-shaped groove 4, a certain gap is kept between the scraping blade 5 and the grinding roller 1, connecting plates 6 are fixed on two sides of one end, away from the grinding roller 1, of the U-shaped part 2, and a cross beam 7 is connected on the connecting plates 6.
Specifically, be connected with connecting rod 8 on the crossbeam 7, the 8 lower extremes of connecting rod are connected with motor fixing base 9, are connected with motor 10 on the motor fixing base 9, and the output of motor 10 is connected with first gear 11, is connected with second gear 12 on the axostylus axostyle 3, and first gear 11 is connected with the meshing of second gear 12, and motor 10 can drive the rotation of grinding roller 1.
Specifically, screw holes are formed in the connecting plate 6 and the connecting rod 8, and the connecting plate 6, the connecting rod 8 and the cross beam 7 are connected through bolts, so that replacement is convenient.
During the use, through setting up doctor-bar 5, can prevent that raw coal from attaching to on the grinding roller, prevent effectively that grinding roller 1 from blocking and can not the rotation or rotation speed is low excessively, block when grinding roller 1 and can not the rotation after, steerable motor 10 rotates, under the combined action of motor 10 and mill, drives grinding roller 1 and rotates to smash the great raw coal of volume, prevent that grinding roller 1 from blocking can not the rotation, in order to improve the coal-grinding efficiency.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
