Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.

As shown in fig. 1, the upper part of the multi-stage sieve washing drum 2 is connected with a feeding device 1, and the lower part is connected with a lifting type spiral dewatering device 15. The side surface of the multi-stage sieve washing roller 2 is connected with a driving motor 10, and the multi-stage sieve washing roller 2 is driven to rotate at a high speed by the power provided by the driving motor 10. The outside of the drum is provided with a protective casing 9 (shown in figure 3) to avoid the risk of high speed rotation of the drum.
