Air flow and multi-stage drum type electrostatic combined foreign fiber separation device

Abstract

The invention relates to an air flow and multi-stage drum type electrostatic combined foreign fiber separation device, in particular to the air flow and multi-stage drum type electrostatic combined foreign fiber separation device during unginned cotton processing. The separation device comprises a feeding port, an air flow separation device housing, an air flow separation foreign fiber inlet, an air flow opening, a foreign matter negative pressure conveying pipeline, a conveying slide plate, an electrostatic separation device housing, a motor, a roller, a pulley, a belt, an electrode plate, anelectrostatic electrode, an electrostatic separation foreign fiber inlet, a hair brush, a protective cover, a high-voltage electrostatic generator, a grounding terminal and an unginned cotton outlet;compared with the prior art, the device adopts the principle of air flow and multi-stage drum electrostatic combined sorting, and carries out air flow and multi-stage drum electrostatic combination sorting on foreign fibers, the elimination rate of the foreign fibers is higher, and the efficient separation of the unginned cotton and the foreign fibers can be achieved without damage.

Description

technical field [0001] The invention relates to a device for separating foreign fibers in the process of seed cotton processing, in particular to a device for separating foreign fibers combined with airflow and multi-stage drum-type static electricity, which belongs to the field of agricultural machinery. Background technique [0002] my country is a big country of cotton production and consumption. Cotton is easily mixed with foreign fibers such as residual film and hair during the process of harvesting, packaging, handling, loading and unloading and storage. If the mixed foreign fibers are not removed during seed cotton processing, the quality of cotton yarn and textiles will be seriously affected, and economic losses will be brought to cotton processing enterprises. [0003] At present, the published foreign fiber separation device such as CN200820103970.4 uses a mechanical method to clean foreign fibers, but it can only remove relatively large impurities, and cannot remo...

Problems solved by technology

If the mixed foreign fibers are not removed during seed cotton processing, the quality of cotton yarn and textiles will be seriously affected, and economic losses will be brought to cotton processing enterprises.

[0003] At present, the published foreign fiber separation device such as CN200820103970.4 uses a mechanical method to clean foreign fibers, but it can only remove relatively large impurities, and cannot remove small foreign fibers such as small debris, residual film, and hair strands; CN201110324521.9 Use electrostatic method to separate foreign fibers, charge the seed cotton during transportation on the conveying mesh belt, and blow off the foreign fibers adhering to the mesh belt with the help of wind force, the charging time is short, and the removal rate of foreign fibers is low ; CN201610356118.7 adopts a multi-stage conveying mesh belt, and carries out the cleaning of foreign fibers through static electricity, and through the tumbling of the seed cotton in the process of transferring step by step between the conveying belts, the contact area between the mesh belt and the conveying belt is increased, and the foreign fiber is improved.
