Integrated seed cotton vacuum drying and cleaning processing system and operating method thereof

Abstract

The invention relates to an integrated seed cotton vacuum drying and cleaning processing system and an operating method thereof. The processing system is characterized by comprising a seed cotton separator, an electrical heating box, a fluidized-bed type cleaner, and a vacuum drying tower which are arranged integrally; the seed cotton separator comprises an inlet and an outlet of a separator shell, wherein a plucker roller, a tooth-pin roller, and a first seed cotton stripping roller are arranged in the separator shell; the interior of the electrical heating box is divided into a plurality of layers of spaces, and a conveying belt and a plurality of heaters are arranged in each layer of the spaces; an air exhaust port flat plate is arranged in the fluidized-bed type cleaner; a group of jet nozzles are arranged behind the air exhaust port flat plate; a sundry removing auger and an air suction port flat plate are respectively arranged below and above the jet nozzles; a cleaner outlet is arranged on the fluidized-bed type cleaner; the vacuum drying tower is divided into an upper layer space, a middle layer space and a lower layer space; the top of the upper layer space is normally open, and a two halves type upper box door is arranged at the bottom of the upper layer space; a two halves type lower box door is arranged at the bottom of the middle layer space which is connected with a vacuum pump; and the bottom of the lower layer space is normally open, and is provided with a cotton conveying auger.

Description

technical field [0001] The invention relates to a cotton processing system and its operating method, in particular to a seed cotton vacuum drying and cleaning integrated processing system for removing impurities in the seed cotton and its operating method. Background technique [0002] As an agricultural product, seed cotton will be mixed with a certain amount of impurities after it matures, whether it is harvested manually or mechanically. In addition to some harmful inorganic impurities, such as sand, dust, and stones, there are also organic impurities on cotton plants, such as cotton leaves, cotton stalks, cotton shells, cotton bolls, etc.; and mixed into seed cotton during harvesting, transportation, and drying. Plastic film, drip irrigation tape, colored wool, hemp rope, variegated cloth, animal feathers, human hair, nylon rope ends, plastic braided silk, etc. Therefore, before the ginning process, it is necessary to remove impurities from the seed cotton. The hand-pi...
