The utility model belongs to the technical field of raw
wool cleaning, and particularly discloses a centrifugal negative pressure type raw
wool primary cleaning device which mainly comprises a body and a cover body, the cover body is used for sealing the body, a liquid inlet and a negative pressure suction opening are formed in the cover body, the liquid inlet is used for leading cleaning liquid into the body, and the negative pressure suction opening is used for sucking the cleaning liquid into the body. The negative-pressure suction port is used for forming a negative-pressure environment in the body, so that ultra-micro bubbles in raw
wool fibers are separated out by utilizing a negative-pressure low-temperature boiling effect; in addition, a cleaning screen
barrel and a driving motor
assembly for driving the cleaning screen
barrel to rotate are arranged in the body, and separated small bubbles are discharged along with cleaning liquid under the centrifugal effect. Therefore, according to the scheme, the device adopts the negative-pressure low-temperature boiling effect and the centrifugal defoaming technology to
discharge ultra-micro bubbles hidden and filled in the raw wool fibers, the influence of the bubbles on the permeability of the cleaning liquid in the raw wool fibers is reduced, meanwhile, the damage of high temperature to the raw wool fibers is reduced, the cleaning rate and
degreasing rate of the raw wool are improved, and the service life of the raw wool is prolonged. And the subsequent testing or
processing quality of the raw wool is ensured.
