Rotary-cylinder type drying device for drying materials

Abstract

The invention discloses a rotary-cylinder type drying device for drying materials. The rotary-cylinder type drying device comprises an inner cylinder body (1) and an outer cylinder body (2), the innercylinder body (1) and the outer cylinder body (2) are fixedly connected to form a whole, and the left end part and the right end part of the inner cylinder body (1) extend outside the outer cylinderbody (2); the left end part of the inner cylinder body (1) is closed, and the right end part of the inner cylinder body (1) is provided with an air inlet (3); a heat energy blower is connected to theair inlet (3), and an air supply pipe arranged in the axial direction of the inner cylinder body is arranged in the position, located on the left side of the air inlet (3), in the inner cylinder body(1); and a plurality of air discharging holes (5) are distributed on the cylindrical surface of the inner cylinder body (1), the outer wall of the outer cylinder body (2) is provided with a bin door (6), and a plurality of drainage holes (7) are distributed on the cylindrical surface of the outer cylinder body (2). The rotary-cylinder type drying device for drying the materials has the beneficialeffects that one machine has many functions, the structure is compact, the labor intensity is reduced, energy saving and environmental protection are achieved, crops are uniformly and rapidly dried with no damage to the crops, and meanwhile, the crops with different sizes and types can be dried, and operation is simple.

Description

technical field [0001] The invention relates to the technical field of drying crop products, in particular to a drum type drying device for drying materials. Background technique [0002] my country is a large agricultural country, and the traditional natural drying method has been used for thousands of years. my country is rich in various agricultural and sideline products such as rice, corn, wheat, sorghum, Alisma, Chuanxiong, Panax notoginseng, ginger, and betel nut. All these agricultural products contain moisture. In order to prevent the agricultural products from being damp and moldy, the agricultural products need to be aired manually. Although to a certain extent, the drying cost is saved, there are some disadvantages in this drying method. First, it depends on manual drying, which consumes a lot of labor. [0003] For massive Chuanxiong, Alisma, and ginger, coal-burning methods are also used to dry agricultural products, that is, the agricultural products are place...

AI Technical Summary

Problems solved by technology

Although to a certain extent, the drying cost is saved, but this drying method has some disadvantages. First, it depends on manual drying, which consumes a lot of labor.

[0003] For massive Chuanxiong, Alisma, and ginger, coal-burning methods are also used to dry agricultural products, that is, the agricultural products are placed on the mesh rack above the steel plate, and the workers burn coal under the steel plate. The heat released by burning coal passes through the steel plate. The upper mesh material rack is transmitted to the agricultural products to realize the drying of the agricultural products. However, workers still need to turn the materials during the drying process, which also increases the labor intensity of the workers.

The cost of burning coal is high, which increases the cost

When coal is burned, a large amount of harmful gas and dust are produced, which seriously pollutes the environment

Burning coal can easily burn agricultural products

There are also drying towers that use lifting buckets to lift grains from top to bottom, and use specific falling points to dry them with hot air. However, this drying method can only dry granular agricultural products, but cannot dry large-sized agricultural products, such as Alisma. , betel nut, ginger, etc.
