Tower type multi-stage electrostatic zero-damage foreign fiber separating device

Abstract

The invention relates to a foreign fiber separating device, in particular to a tower type multi-stage electrostatic zero-damage foreign fiber separating device. The tower type multi-stage electrostatic zero-damage foreign fiber separating device comprises a rack, a motor, a feed inlet, a conveying mesh belt, a transmission gear, a high voltage electrostatic generator, an electrode plate, a sawtooth-shaped electrode, a seed cotton sliding plate, a hairbrush, a foreign fiber conveyor belt and a foreign matter negative-pressure output pipeline. Compared with the prior art, by adopting a tower type multi-stage electrostatic separating principle, the electrical charge time of foreign fiber during a separating process is longer, foreign fiber removing on multiple a plurality of contact surfaces of cotton seeds is realized through falling and rolling of the cotton seeds, and the separating efficiency is higher; a rapid collection of impurities such as dust and hairs can be completed while the foreign fiber is collected by using the foreign matter negative-pressure output pipeline, and secondary pollution is avoided; meanwhile, a zero-damage separation on the foreign fiber of the cotton seeds is realized through adopting modes of static electricity and falling and rolling of the cotton seeds.

Description

technical field [0001] The invention relates to a seed cotton foreign fiber separating device, in particular to a tower-type multi-stage electrostatic non-damaging foreign fiber separating device, which belongs to the field of agricultural machinery. Background technique [0002] In order to reduce the cleaning pressure of foreign fibers in lint and improve the quality of cotton textiles, it is necessary to separate foreign fibers in the seed cotton stage. Currently, published foreign fiber separation devices such as CN201220109068.X and [0003] CN201320145164.4 all adopt the separation method combining mechanical wind force, and this method not only cannot efficiently separate the foreign fibers but also easily causes damage to the cotton fiber, which seriously affects the quality level of the cotton after processing. Electrostatic foreign fiber separation device such as CN201110324521.9 adopts the separation method combined with electrostatic wind force, but its charging...

Problems solved by technology

[0003] CN201320145164.4 adopts a separation method combining mechanical and wind power, and this method not only cannot efficiently separate foreign fibers but also easily damages cotton fibers, seriously affecting the quality level of cotton after processing

Electrostatic foreign fiber separation device such as CN201110324521.9 adopts the separation method combined with electrostatic wind force, but its charging time is short due to length limitation, and the seed cotton cannot be rolled during the transportation process, and can only separate the foreign fiber in contact with the mesh belt. Fiber, low separation efficiency, but can be used as a reference

The charging time is short and the seed cotton is not easy to tumble multiple times during the separation process, which is the bottleneck of the technology promotion of the electrostatic foreign fiber separation device.
