Cotton drying machine

Abstract

The invention discloses a cotton drying machine. The cotton drying machine structurally comprises a machine box, wherein supporting legs are arranged under the machine box; a power cavity is formed inone end of the machine box, a coil capable of heating after being electrified is arranged in the power cavity, a power mechanism is arranged at one end of the power cavity, a drying cavity is connected to one end of the power cavity, first holes are formed in the inner wall of the drying cavity, and a beating mechanism is arranged in the drying cavity; an impurity cavity is formed outside the drying cavity, exhaust cavities are formed at the upper part of the impurity cavity, sliding grooves are formed in the exhaust cavities, external sliding rails are arranged at one ends of the sliding grooves, and first baffles are arranged in the sliding rails; and a discharging opening and a feeding opening are formed in the upper portion of the machine box, and a turning cover is arranged on the feeding opening. The cotton drying machine has the beneficial effects that the beating mechanism can stir cotton, so that heating is more evenly, the drying efficiency is improved; the beating mechanismcan also beat caked cotton lumps after water absorption, so that cotton is separated, meanwhile, the cotton is fluffed out, and the cotton quality is improved; and cotton discharging is controlled bymanually controlling opening and closing of exhaust holes, and the cotton can be discharged from the discharging opening only under the condition that the cotton is completely dry and fluffy.

Description

technical field [0001] The invention belongs to the textile field and relates to a cotton processing device, in particular to a cotton dryer. Background technique [0002] The cotton dryer turns the fresh cold air from the outside directly through the air inlet and exchanges heat with the heater to become dry hot air. The hot air moves forward from the tail and fully contacts with the cotton, directly transferring the heat energy to the material to make the moisture of the material dry. It is continuously evaporated in the cylinder, but the drying time is long and the working efficiency is low. For this reason, people have carried out long-term exploration, put forward various solutions. [0003] For example, the Chinese patent literature discloses a cotton dryer [Application No.: 201710604974.4], which includes a drying box, a condensation box, a cotton inlet channel, a hot air channel, a condensation pipe, a circulating pump, a motor, a stirring rod, and a cotton outlet c...

AI Technical Summary

Problems solved by technology

[0004] The residence time of the cotton in the drying box in the above scheme is too short. When the moisture content of the cotton is high, the cotton is not completely dried, and the drying quality of the cotton cannot be guaranteed.
