Due to the special property of the mechanical cotton, a large amount of foreign fibers mainly used as mulching films are mixed in the mechanical cotton harvesting process. The existing cotton picking and cleaning equipment cannot effectively remove foreign fibers such as residual films, meanwhile, the residual films are broken and mixed into lint through a plurality of impurity cleaning processes, the foreign fibers mixed into seed cotton are easily broken into scattered single fibers, and the foreign fibers are difficult to clean in textile processing. During spinning, single fibers are scattered to easily break cotton yarn, so that the production efficiency is reduced; when weaving, the cloth surface quality is affected; during dyeing, the appearance is affected due to different colors, and the quality of cotton yarn and cloth cover is greatly damaged. When cotton cloth and cotton yarn are dyed, the dyeing rate of cotton fibers and foreign fibers is inconsistent, so that obvious defects and color spots appear when cotton fabric is dyed, a large number of defective products are caused, the normal production order and foreign trade export are directly influenced, the income of cotton farmers is reduced due to the mixing of the foreign fibers such as mulching films, the defects of the fabric are increased due to the mixing of the foreign fibers such as mulching films, the dyeing is uneven, the quality of cotton fabrics is seriously influenced, and huge economic loss is caused. The detection and elimination of foreign fibers in cotton has become a central problem of concern in the cotton industry worldwide, so that the development of an effective device for removing the foreign fibers such as mulching films is necessary.

Chinese patent No. CN201610356118.7 adopts multistage conveying mesh belts, carries out foreign fiber cleaning through an electrostatic mode, increases the contact area of mesh belts and conveying belts through rolling of seed cotton in a step-by-step transmission process between the conveying belts, and improves foreign fiber removing efficiency. Chinese patent No. CN201810507439.1 adopts an air flow and multistage drum-type static combined method to remove foreign fibers, the whole device is of a single-channel structure, and the separation efficiency is limited. The Chinese patent number CN201922074723.7 adopts electrostatic adsorption, and is a multi-channel combined operation, so that the separation efficiency is improved. The invention provides an electrostatic seed cotton foreign fiber removal modularized device, which is a core of a multi-channel mechanical seed cotton foreign fiber electrostatic separation device, and has the innovation point that a double-stage corona electrode and electrostatic electrode structure are adopted, and negative pressure wind suction type impurity removal is adopted, so that foreign fibers mainly based on mulching films in mechanical cotton can be effectively separated and removed, separation of seed cotton and foreign fibers can be completed under the condition of no damage, and the electrostatic seed cotton foreign fiber removal modularized device can also be matched with a subsequent invention device.
