Description

Light miscellaneous separator

technical field

The invention relates to grain processing equipment, in particular to a light impurity separator for removing stalks and husks in grains.

The separation shell is composed of the upper chamber 2 and the lower chamber 3 which are connected by the inner cavity; the side wall of the upper chamber 2 of the positive conical cylinder structure is provided with a feeding port, which is connected with the external feeding pipeline The feed pipe 4 extends into the upper chamber 2 from the feed port, and a leveling disc 5 driven by a power source to rotate horizontally is arranged near the bottom of the upper chamber. Corresponding to the center of the upper chamber; the mouth of the top of the upper chamber is connected with an exhaust pipe 6 with an adjustable damper, and the exhaust pipe 6 is connected to the external centralized air network system; There is an air chamber 7 in the ring, and an air inlet is opened on the side wall of the air chamber 7 (the side wall of the air chamber is the air inlet plate); the lower chamber 3 is an inverted cone structure, and the discharge port at the bottom of the lower chamber passes through The discharge pipe 8 communicates with the external collecting device.

As shown in Figure 3 to Figure 8, in order to ensure the uniform dispersion of materials and improve the effect of impurity removal, the leveling disc 5 is composed of multiple (16 pieces can be selected) approximately rectangular blades 9 (the blades 9 are cut by high-strength wear-resistant plates processed) and welded after bending, the three corners of the blade 9 (see Figure 8) are right angles, and the fourth corner extends outwards with two approximately triangular xiphoids, one large and one small, and the larger triangular The xiphoid of the xiphoid is folded out at a certain angle along the crease line 10 (the angle can be adjusted according to the size of the particles of the cleaning material. When removing materials with large particles such as soybeans and corn, because of their better fluidity , the angle can be larger; when removing materials with smaller particles such as wheat, the angle can be adjusted to be slightly smaller), so that the end face shape of the blade 9 is approximately L-shaped; It is a conical protrusion, and a feeding channel is formed between two adjacent blades on the outer edge.

In order to ensure a more uniform distribution of the material falling on the leveling pan 5, a support frame 11 is arranged under the leveling pan 5, and a transmission screw 12 is installed longitudinally sliding in the center of the support frame 11, and the leveling pan 5 is set on the upper part of the transmission screw 12 , the bearing cover 13, bearing 14 and bearing seat 15 arranged in sequence on the transmission screw in the conical protrusion at the center of the leveling disc 5 are combined with the leveling disc 5 through connecting bolts 16, and the self-leveling disc 5 is conical A compression bolt 17 is screwed into the top of the bearing seat 15 in the raised central hole; the lower part of the drive screw 12 extends from the lower chamber 3 and passes through the adjusting nut 18 matching its thread, and at the lower end of the drive screw 12 A motor 19 is connected to the external drive; a positioning through hole is provided on the side wall of the adjusting nut 18, and a positioning screw 20 is screwed on it.

Before work, first adjust the position of the feed pipe 4 so that the center of the outlet is aligned with the center of the uniform material pan 5, and then adjust the gap between the uniform material pan 5 and the mouth of the feed pipe 4 by adjusting the nut 18. Finally, the set screw 20 is tightened to start the motor 19, which drives the leveling pan 5 to rotate at a uniform speed, so that the miscellaneous materials fall evenly around the leveling pan 5.
