Seed cotton purification device

Abstract

The invention provides a seed cotton purification device which comprises a cotton feeding channel and a cotton discharging channel. The cotton feeding channel and the cotton discharging channel are communicated inside and used for conveying cotton flows. The seed cotton purification device is characterized in that the cotton feeding channel and the cotton discharging channel are in arc connection through a connection pipe which is a bend, a nozzle is arranged at the turn of the bend, and a high-pressure air pipe is arranged at the inlet of the cotton feeding channel. Due to the fact that the bent connection pipe is arranged between the cotton feeding channel and the cotton discharging channel, and the nozzle is arranged at the connection pipe, the cotton flows sequentially pass through the cotton feeding channel, the connection pipe and the cotton discharging channel under the action of high-speed airflow to be conveyed out, large-density impurities in the cotton flows can not easily change direction at the nozzle in the high-speed airflow and are discharged from the nozzle, and cotton fibers are small in density and large in inertia so as to go forwards along with the high-speed airflow until being conveyed out of the cotton discharging channel. After the seed cotton purification device is used, the noil rate of raw cotton is 0.2-0.4%, the impurity rate of noil is 85-90%, and the seed cotton purification device has the advantages of being low in noil rate and high in impurity rate of noil.

Description

technical field [0001] The invention relates to a cotton flow impurity removal device, in particular to a cotton flow impurity removal device for removing large-density impurities in the cotton flow, and belongs to the technical field of cotton spinning. Background technique [0002] In the process of opening and cleaning cotton, since the cotton fibers of raw cotton are mixed with dense and hard impurities such as cottonseed, seed cotton, and sterile seeds, these dense and hard impurities will damage the machine during cotton opening and blending. Parts, especially the beaters, not only increase production costs, but also reduce production efficiency. Contents of the invention [0003] In order to solve the deficiencies in the background technology, the purpose of the present invention is to overcome the defects of the background technology, and provide a cotton stream impurity removal device, which can effectively remove hard and dense impurities in raw cotton, and has ...
