摘要： A secondary impurity-removal recycling system for refining cotton is provided. A first feeding opening is set on the side of the first bin shell, in which the first drum is movably installed, and the first drum is tube shaped. A first mesh is set on the peripheral wall of the first drum, and a first scraper is set at the first feeding opening inside the first bin shell. One end of the first drum is provided with a first impurity-discharging pipe, the outer periphery of which is provided with a first annular hump. The first connecting sleeve is installed on the outer wall of the first bin shell, and the first impurity-discharging pipe is movably stuck in the first connecting sleeve through the first annular hump, and communicates with the first connecting sleeve. The first induced draft fan communicates with the first connecting sleeve through a first air duct.

摘要： An impurity-removal system for refining cotton is provided. In the system, the bottom of the first bin shell is open, and the top of the first bin shell is provided with a first discharge opening, the air inlet of the first induced draft fan communicates with through a first air duct. The front wall of the first bin shell is provided with a first feeding opening, from which the rear of the conveying mechanism penetrates into the first bin shell, and the pressuring roller is installed on the first feeding opening of the first bin shell, and located above the mechanism. The first opening roller is movably installed in the first bin shell, located at the rear of the conveying mechanism, and first saw teeth in a row are set on the periphery of the first opening roller. The first motor is drivingly connected with the first opening roller.
