the air volume adjusting fixing piece is connected with the air volume adjusting shaft through a first common flat key 12 and elastic check rings 24 for a second shaft (one piece at each of two ends of the air volume adjusting shaft). After the air volume adjusting plate is adjusted in position, the air volume adjusting fixture is pressed against the screw hole plate 23 by the bolt through the circular arc-shaped through hole 1201, thereby fixing the air volume adjusting fixture, the air volume adjusting shaft 21, and the air volume adjusting plate 34.
The screw hole plate is provided with three screw holes so as to reduce the circumferential dimension of the circular arc-shaped hole of the air volume adjusting fixing piece and the circumferential dimension of the whole piece as much as possible, at least one screw hole is arranged in the range of the circular arc-shaped through hole in the adjusting range of the air volume adjusting plate, namely, the air volume adjusting fixing piece is pressed on the screw hole plate by one bolt on each side of the axial direction of the feeder.
The axial clearance between the air quantity adjusting fixing piece and the screw hole plate is small, the air quantity adjusting fixing piece and the screw hole plate can be tightly pressed through small elastic deformation of the air quantity adjusting fixing piece under the pressure of the bolt, and the original shape of the air quantity adjusting fixing piece is restored after the bolt is loosened.
The material enters the feeder from the top feeding port 1, the material is driven to fall onto the air volume adjusting plate 34 by the rotation of the feeding rotor 11, the material flows downwards through the air volume adjusting plate 34 (see figure 3), when the material flows down the air volume adjusting plate 34, an air channel is formed between the air volume adjusting plate 34 and the air deflector 35 under the action of wind, and the material is blown to the left side to descend along the shell wall 2 and enters the crusher at the lower part through the discharge port 18; and the impurities with specific gravity larger than that of the materials, such as brick slag, stones, iron blocks and the like, fall into the drawer 15 relatively less influenced by wind.
Referring to fig. 1, 2 and 3, when the feeder is cleaned, the drawer 15 is pulled out to pour out the impurities, and then the drawer is placed in the shell and placed in the original position.
As shown in figure 3, the outside air enters the feeder through the air inlet 28 at the right end, enters the lower crusher through the discharge port 18, the end of the crushing system is provided with the draught fan (the draught fan device is required to be arranged for cooling the pulverized material) to lead the material out, and the purification of the material through the feeder depends on the specific gravity separation principle, so that the material and the impurities are more thoroughly separated by adjusting the air volume adjusting plate 34 (see figure 3).
The air quantity can be adjusted by twisting the hexagons at the two ends of the air quantity adjusting shaft 21 by using an adjustable wrench to drive the air quantity adjusting arm 22 and the pulley 19, and then the pulley drives the air quantity adjusting plate 34 to rotate, so that the size of the gap between the air quantity adjusting plate 34 and the air deflector 35, namely the sectional area of the air channel, is changed, the air speed in the air channel is adjusted, and the cleanness degree of material cleaning is determined.
It can be seen from fig. 5-9 that the blades on both sides of the partition are staggered by a certain angle.
