Air outlet net cleaning device

Abstract

The invention discloses an impurity cleaning device of an air outlet mesh. The device is provided with an upper-layer air exhaust chamber and a lower-layer air exhaust chamber, an overflow cotton conveyor belt is arranged between the two layers of the air exhaust chambers and a cotton discharge port is arranged at the tail end of the overflow cotton conveyor belt; and a foreign fiber conveyor belt is arranged at the bottom of the lower-layer air exhaust chamber and an impurity discharge port is arranged at the tail end of the foreign fiber conveyor belt. Impurity blocking meshes are arranged on the outer side surfaces of the upper-layer air exhaust chamber and the lower-layer air exhaust chamber. A track is arranged on the upper side of the impurity cleaning device of the air outlet mesh,a mobile fan is further mounted on the track, a vertical air knife is mounted on an air outlet of the mobile fan and travel switches are mounted on two sides of the track respectively. By adopting the device, seed cotton which is blown up along with air pressure in a foreign fiber clearing device can be effectively separated when the seed cotton is in the suspended rolling state, and the barrier type conveyor belt and the belt type conveyor belt are adopted for conveying different separated materials respectively, thereby achieving the purpose of effective separation.

Description

technical field [0001] The invention belongs to the technical field of cotton impurity removal, in particular to an air outlet net impurity removal device. Background technique [0002] Raw seed cotton is unavoidably mixed with a large amount of impurities during the harvesting process, storage and transportation process of farmers, such as cotton leaves, colored threads, ropes, woven bag silk, chemical fiber silk, plastic sheets, films, feathers, hair and sand, gravel etc. These foreign fibers are cut into pieces after ginning, and after being mixed with cotton fibers, cleaning is very difficult. How to effectively remove these impurities is a difficult problem in the cotton processing process. The traditional manual picking method not only consumes a lot of labor, but also has low removal efficiency, and the removal rate does not exceed 60%. These foreign fibers seriously affect the quality of spinning, and the cloth is not easy to be colored when dyed, leaving secondar...

Problems solved by technology

The inner surface of the miscellaneous screen of this structure is often sealed due to the continuous accumulation of impurities, which affects the smoothness of ventilation, directly affects the uniform air pressure inside the foreign fiber removal device, and affects the cleaning effect inside the foreign fiber removal device
