the upper sleeve is provided with a lantern ring 7 capable of moving up and down, and the lantern ring 7 can reset upwards; a plurality of blades 8 are uniformly distributed on the circumference of the lantern ring 7;

the middle part of the outer shell 1 is provided with a discharge port 9, and a baffle 10 which is parallel and level with the lower end of the discharge port 9 is arranged in the outer shell 1.

In order to realize the up-and-down movement of the lantern ring 7, a pressure spring 11 is connected between the lantern ring 7 and the rotating shaft 3.

In order to realize the adjustment of the up-and-down movement of the rotating shaft 3, a positioning disc 12 is arranged at the lower end of the rotating shaft 3, a box body 13 is sleeved outside the positioning disc 12, an end face bearing is arranged between the box body 13 and the positioning disc 12, a bolt 14 is fixed at the lower end of the box body 13, and the lower end of the bolt 14 is arranged at the outer side of the outer shell 1 and is provided with a nut 15.

In order to realize the stable support of the sleeve 2, the sleeve 2 is sleeved with a tapered roller bearing, a connecting rod is welded on the outer ring of the bearing, and the other end of the connecting rod is fixed on the inner wall of the outer shell 1.

In order to achieve a rotation of the sleeve 2, said sleeve 2 is driven to rotate by a motor.

In order to realize the up-and-down movement of the rotating shaft 3 relative to the sleeve 2 and the up-and-down movement of the lantern ring 7 relative to the rotating shaft 3; the rotating shaft 3 is provided with a vertical key groove, and the inner walls of the lantern ring 7 and the sleeve 2 are provided with flat keys which are arranged in the key groove.

In order to realize the positioning and fixing of the orifice plate 5, the diameter of the outer edge surface of the orifice plate 5 is larger than that of the inner edge surface of the outer shell 1; a connecting plate 16 is fixed on the pore plate 5, a positioning plate 17 is fixed on the outer shell 1, positioning holes are formed in the connecting plate 16 and the positioning plate 17, and pins 18 are inserted into the positioning holes.

The utility model discloses during the use, at first because orifice plate 5 in this device is detachable construction, consequently can replace through the orifice plate 5 of making different mesh numbers. During specific replacement, because the compression roller 6 is pressed on the pore plate 5 in a normal state, the pore plate 5 cannot be drawn out, firstly, the nut 15 on the bolt 14 needs to be screwed, and the rotating shaft 3 is not pressed on the pore plate 5; the pin 18 is then removed, and the aperture plate 5 can be withdrawn.

After the pore plate 5 is drawn out, the lantern ring 7 moves upwards to reset under the action of the pressure spring 11; therefore, when a new orifice plate 5 is installed, the left orifice plate 5 can be drawn out and a new orifice plate 5 can be inserted in a mode of replacing the orifice plates 5 in sequence on one side; then drawing out the right pore plate 5 and inserting a new pore plate 5; finally, the orifice plate 5 is positioned and fixed by the pins 18, so that the orifice plate 5 can be replaced. If the pore plates 5 on the two sides are pulled out, the user needs to stretch into the through groove 4 by hands to press the lantern ring 7 downwards.
