Device for pretreating refined cotton and method of use of same

A device for pretreating refined cotton, comprising a body frame (1), a pretreatment drum (5), a material-allocating mechanism (8), a reciprocating swing mechanism (10), a spraying mechanism (12), a scraping mechanism (11), and a power drive mechanism (9);

• wherein said body frame (1) includes a lower baseplate (2), four columns (3) mounted on an upper surface of the lower baseplate (2), and an upper baseplate (4) mounted at a top of the four columns (3);
• wherein first rotation shafts (6) are fixed on front and rear sides of said pretreatment drum (5), a lateral support (7) is rotationally installed on an outer surface of the first rotation shaft (6), and fixedly on an upper surface of the upper baseplate (4), a discharge door is hinged on a back of said pretreatment drum (5), an arc-shaped material receiving cover (24) is fixedly installed on the upper baseplate (4), a liquid outlet (66) facing the arc-shaped material receiving cover (24) is opened on an outer surface of said pretreatment drum (5), a strainer (65) is installed on an inner wall of the liquid outlet (66), a connecting tube (25) is installed on the arc-shaped material receiving cover (24), and passes through the upper baseplate (4) and extends to a lower part of the upper baseplate (4);
• wherein said material-allocating mechanism (8) is arranged on said pretreatment drum (5), used to perform alkali pretreating on materials added into said pretreatment drum (5);
• wherein said reciprocating swing mechanism (10) is arranged on the upper surface of the upper baseplate (4), used to drive said pretreatment drum (5) to swing left and right around an axle center of an axis where the first rotation shaft (6) is positioned;
• wherein said spraying mechanism (12) is arranged on the lower baseplate (2), used to spray lye into said pretreatment drum (5) to perform alkali treatment, and a residue-filtering strainer (13) is arranged on said spraying mechanism (12);
• wherein said scraping mechanism (11) is arranged on said spraying mechanism (12), used to scrape the materials returned to the residue-filtering strainer (13) via the connecting tube (25), ensuring the recycling of lye;
• wherein said power drive mechanism (9) is arranged on a side of the upper baseplate (4), used to drive said reciprocating swing mechanism (10) and said scraping mechanism (11) to synchronously operate.
