Detailed Description
The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.
The grinding main machine abrasive material impurity removing structure comprises a main machine base 1, an air return box 2 and a conveyor 6, wherein a seat cavity of the main machine base 1 is a cavity with an open top, and a scraper knife mechanism 5 which rotates synchronously with a main machine main shaft 4 is arranged in the seat cavity, as shown in figure 1.
The upper part of a seat cavity of the host machine base 1 is designed as an installation position of a grinding ring 3, the middle part of the seat cavity is designed as an air inlet position of circulating air, and the lower part of the seat cavity is designed as a deposition position of materials; the main machine base comprises a main machine base body 1, and is characterized in that an upper horizontal flange platform I1-3 and a lower horizontal flange platform II 1-4 are designed on the side portion of the main machine base body 1, the flange platform I1-3 is arranged on the upper portion of a grinding ring installation portion of a seat cavity, the flange platform II 1-4 is arranged at the junction of an air inlet position and a deposition position of the seat cavity, and the air inlet position of the seat cavity is arranged at the air inlet position, air inlets 1-1 are uniformly distributed on the circumference of the side portion of the main machine base body of the base 1 above the flange platform II 1-4, each air inlet 1-1 is communicated with the seat cavity, the deposition position of the seat cavity is opposite, and a material outlet 1-2 communicated with the seat cavity is arranged on the side portion of the main machine base body 1 below the flange platform II 1-4, as shown in figures 1 and 2.
The installation position of seat chamber is coaxial to be provided with grinding ring 3, install the grinding roller mechanism through fixed roll frame 7 on the host computer main shaft 4, the last circumference equipartition of grinding roller mechanism has the grinding roller 8 of grinding the district of forming with grinding ring 3 counterpoint, is equipped with the scraper mechanism of synchronous pivoted with spiller mechanism 5 or host computer main shaft 4 in the deposit position of seat chamber corresponding to bin outlet 1-2, as shown in figure 1.
The air return box 2 is arranged on the flange platforms I1-3 and the flange platforms II 1-4 around the side part of the base body of the base 1 above the discharge port 1-2, the box body of the air return box 2 covers all the air inlets 1-1, and the horizontal feed end of the conveyor 6 is connected with the discharge port 1-2 on the side part of the base body below the box body of the air return box 2, as shown in figures 1 and 2.
The working principle of the invention is as follows:
the scraper knife mechanism 5 synchronously rotating with the main machine main shaft 4 conveys the materials at the deposition position of the seat cavity of the main machine base 1 upwards to a grinding area between the grinding rollers 8 and the grinding ring 3 from bottom to top, the grinding rollers synchronously rotate with the main machine main shaft 4, and each grinding roller 8 rolls on the grinding ring 3 under the action of centrifugal force to grind the falling materials and the feeding materials of the scraper knife mechanism 5; because the weight of the sundries in the grinding materials is larger, in the conveying process along with the scraper knife mechanism 5, the sundries can slide down on the scraper knife mechanism 5 in a half way and return to the deposition position of the seat cavity due to insufficient inertia, and because the sliding down position of the sundries is lower than the air inlet 1-1, the sundries cannot enter the air return box 2 from the air inlet 1-1; the synchronous rotating scraping mechanism conveys sundries (positioned at the lower part of the material layer) in the material to the discharge opening 1-2, and the sundries are conveyed out by the conveyor 6 through the discharge opening 1-2.
