Embodiment Construction
[0021] The main structure of the self-burning dryer of the present invention is as follows: figure 1 As shown, it includes a frame 1, an electric heater 16, an inner cylinder 7, a small supporting wheel 8, a small support ring 6, a small ring gear 5, a pinion 10, a small speed regulating motor 9, an inner cylinder feeding port 18, an outlet Ash port 15, outer cylinder 4, large support ring 2, large support wheel 13, large gear ring 3, large gear 12, large speed-regulating motor 11, outer cylinder feed port 17, discharge port 14; the axis of the inner and outer cylinders The angle between the line and the horizontal plane is selected to be 15°, and the angle should not be too large, otherwise the size of the trough-shaped supporting roller may not be able to limit the axial slide of the inner and outer cylinders; It is conducive to the circulation of hot air in the inner and outer cylinders, and can accelerate the drying of agricultural waste and wet materials.

The invention relates to a drying technology of agricultural waste wet materials, in particular to a self-burning-type dryer and a drying method thereof. The drying method comprises the steps that firstly, an electric heater is started to heat an inner cylinder, when the temperature in the inner cylinder is increased to 300-500 DEG C, a small speed adjusting motor and a large speed adjusting motorare started, the inner cylinder and an outer cylinder immediately rotate, meanwhile, the agricultural waste wet materials are added into a feeding inlet of the inner cylinder and a feeding inlet of the outer cylinder, and the agricultural waste wet materials are dried when gradually downwards moving in the inner cylinder and are ignited when reaching the lower section of the inner cylinder; afterburning is stable, the electric heater is stopped, subsequent heating of the inner cylinder is completed by self-burning of the agricultural waste wet materials which are continuously added and dried, and burned ash slag slides out from an ash outlet; and the agricultural waste wet materials in the outer cylinder can be heated through radiant heat generated in the heating process of the inner cylinder, are dried when gradually downwards moving in the outer cylinder, and slide out from a discharging outlet. The energy is saved, and the production cost is low.
Description
technical field [0001] The invention relates to a drying technology for agricultural waste and wet materials (livestock and poultry manure such as pigs and cattle, wet crop stalks cut and crushed, and wet leftovers of agricultural and sideline products, etc.), in particular to a self-immolation dryer and a drying method thereof. Background technique [0002] Livestock and poultry manure such as pigs and cattle in livestock and poultry farms, cut and crushed wet straw of crops in farms, and wet leftovers in agricultural and sideline product processing plants are usually used as one of the raw materials for fertilizers and feeds, but they must first pass through Dry to prevent raw materials from rotting and deteriorating. Patent 2015103595102 discloses a "double-drum crop dryer". In the process of drying crops, the heating pipe is heated from the beginning to the end, and the power consumption is large, the drying cost is high, and the structure is relatively complicated.
