Description

Technical Field

[0001] The utility model relates to the technical field of wool dewatering, in particular to a wool dewatering device. Background Art

[0002] Raw wool refers to the unprocessed animal hair cut from animals, such as wool, rabbit hair, etc. Raw wool is attached with grease, sweat, and many impurities. Therefore, it is necessary to wash the raw wool to remove the grease, sweat, and impurities attached to the raw wool to obtain clean wool. Clean wool usually has strong water absorption. After washing, the clean wool will absorb a large amount of water. Therefore, it is necessary to separate the wool from the water. The water-soaked clean wool is squeezed by a wool dewatering device to dehydrate the clean wool.

[0003] The existing wool dewatering device usually manually manipulates a push rod to squeeze the water-soaked wool in a water squeezing cylinder to dehydrate the wool. However, manual operation is not only time-consuming and laborious, but also easily leads to unstable dehydration pressure of the wool dewatering device and unqualified wool dehydration effect. At the same time, it is difficult to accurately control the dehydration time, and the work efficiency is low. Content of the Utility Model
