Cotton fiber drying and cooling system

Abstract

The invention discloses a cotton fiber drying and cooling system which comprises a drying box body and a cooling box body, wherein the drying box body is internally provided with a transverse clapboard; the transverse clapboard divides the interior of the drying box body into a drying chamber at the upper end and a heating chamber at the lower end; multiple vent holes are uniformly distributed in the transverse clapboard; the side walls of two ends of the drying chamber are respectively provided with an inlet and an outlet which are corresponding to each other; the inlet end of the drying chamber is provided with an inlet cotton conveying curtain, and the outlet end of the drying chamber is provided with a middle conveying curtain; the drying chamber is internally provided with multiple groups of oblique upward conveying curtains and oblique downward conveying curtains, which are matched with each other; the oblique upward conveying curtains and the oblique downward conveying curtains constitute inverted V-shaped drying channels; the inner wall, positioned at the tops of the oblique upward conveying curtain and oblique downward conveying curtain in each group, of the drying box body is rotatably provided with a stripping roller; the other end of the middle conveying curtain extends into the inlet end of the cooling box body. The cotton fiber drying and cooling system is simple in structure, uniform and full in drying, small in equipment size, improved in drying stroke and high in cooling efficiency.

Description

technical field [0001] The invention relates to the field of textile machinery and equipment, in particular to a cotton fiber drying and cooling system. Background technique [0002] The needle felt impregnation production line currently used in the market is basically composed of a bale opener, a pre-opener, a main opener, a cotton feeder, a pre-carding machine, a web-laying machine, a main carding machine, a bridge curtain, a dipping machine, Composed of a dryer and a winder, it can be used for impregnation of needle-punched cotton fibers. Dryers are used in processing engineering, usually by heating and drying, to achieve the temperature required by the required processing technology to remove moisture in the fabric, and at the same time adjust and maintain a certain size to complete the required process. In the existing drying process, the needle felt is conveyed in a straight line when it is conveyed in the oven, and the hot air blown by the circulating fan sweeps the ...

AI Technical Summary

Problems solved by technology

In the existing drying process, the needle felt is conveyed in a straight line when it is conveyed in the oven, and the hot air blown by the circulating fan sweeps the surface of the needle felt and leaves quickly, which cannot fully transfer the heat to the needle felt Realize sufficient heating and drying, and the running stroke of the needle felt in the oven is short, and the ambient temperature in the oven cannot be fully used for heating and drying; and the cooling of the existing needle felt after drying is usually blown by a fan, and the cooling efficiency lower
