The effect of the supporting circular plate is that the discharge hole is large and distributed in a plurality of sizes, the discharging cavity of the spiral core pipe can be supported through the supporting circular plate, the strength is improved, the phenomenon that the material conveying pressure is large and the discharging cavity is opened and deformed is avoided, the material can be discharged to the other side of the discharge hole through the through hole, and the phenomenon that the material is accumulated in the discharging cavity due to the fact that the material is large in quantity and pressure is avoided.

Further perfecting, a round block is fixed in the cavity of the spiral core pipe, a through hole for the feed pipe to pass through is formed in the round block, and blocking bristles attached to the outer contour of the feed pipe are fixed on the through hole; the round block is provided with a mounting hole, a ball bearing is arranged in the mounting hole, and the feeding pipe is inserted in the inner ring of the ball bearing. The round block and the through hole have the effects that the feeding pipe is supported, the discharging pipe extends into the cavity of the spiral core pipe, so that the discharging pipe is longer, the discharging pipe can bend downwards when the centrifugal machine transports materials, and the spiral core pipe rotates at a high speed, so that the support of the round block and the through hole can avoid the shaking of the feeding pipe, and the noise of the centrifugal machine is reduced; the effect of blocking the bristles is that the materials can be prevented from flowing back through the through holes, so that the materials are cleaner; the ball bearing has the effect that the ball bearing can be inserted into the feeding pipe, so that the feeding pipe can also pass through the inner ring of the ball bearing without shaking when the spiral core pipe rotates at a high speed, and the shaking of the centrifugal machine is low and the noise is extremely low under the condition of high-speed operation.

The utility model discloses profitable effect is:

(1) the disassembly frequency is reduced;

(2) the abrasion at the discharge port is reduced;

(3) the service life is prolonged;

(4) and the backwater condition is avoided.
