Cotton ginning device capable of preventing negative pressure and realizing efficient flow guide

Abstract

The invention discloses a cotton ginning device capable of preventing negative pressure and realizing efficient flow guide. An air inlet (14) and an air volume adjusting device (16) are arranged at one or two ends of a brush roller (2) of a cotton gin; an air outlet (11) is formed between brush bars or cotton brushing plates at the periphery of a drum of the brush roller (2); an impurity removal combination comprises an impurity removal lattice bar grid (4), a lower impurity removal stranding cage or an impurity suction hole (5); and the impurity removal combination is located on the outer side of the brush roller. An existing drum structure is changed. Under high-speed rotation, the drum not only has the air conveying function and inertial centrifugal force, but also can eliminate the back-suction phenomenon, so that fibers and impurities are located in different positions of an airflow layer under the action of the centrifugal force due to different mass and connecting force; and under the cooperation of the impurity removal combination, the fibers and the impurities are forced to be separated, so that fiber overflow can be prevented. Or an existing cotton supporting plate is changed into the impurity removal combination, and the air inlet position of the brush roller is changed under the attraction of the appropriate air amount, so that the purpose of separating the fibers from the impurities can also be achieved.

Description

technical field [0001] The invention relates to a cotton processing machine, in particular to a high-efficiency ginning device which separates fibers or short fibers in seed cotton from impurities and has the function of diversion and anti-blocking. Prevents clogging during ginning in cotton processing plants. Background technique [0002] During cotton processing, the cotton fibers in the seed cotton are separated from the cotton seeds to form lint, and the linters on the cotton seeds are retained. The gin used should be suitable for all grades of seed cotton with a moisture content of less than 10% and preliminarily cleaned by a seed cotton cleaning machine. The working process of the existing cotton gin includes first-level cleaning of the seed cotton cleaned by the seed cotton cleaning machine, so that some impurities, especially large particles of impurities, and a small amount of seed cotton are also mixed under the action of gravity and centrifugal force. After repea...

Problems solved by technology

However, a problem that is difficult to solve in the current cotton gin is that there are multiple rotating rollers in different directions and some necessary accessories inside the cotton gin. Cotton seeds and sundries produce reflux, which affects the production efficiency of the cotton gin, is not conducive to the effective separation of fibers and impurities, and is easy to cause waste of effective fibers. Repeated cleaning and multiple separation operations are required, resulting in complex equipment, high input costs, and low efficiency.
