Straw granule drying device

Abstract

The invention discloses a straw granule drying device. A feeding spiral conveying shaft is arranged below a dehydrator, one end of the feeding spiral conveying shaft is connected with a motor, the other end of the feeing spiral conveying shaft is connected with an air drying furnace, an air drying sliding plate is arranged in the air drying furnace, a primary conveying belt is arranged below the air drying sliding plate, the end, away from the feeding spiral conveying shaft, of the air drying furnace is connected with a drying machine, electric heating wires are arranged on the periphery inside the drying machine, a drying support is arranged in the middle inside the drying machine, a drying table is fixedly connected to the top of the drying support, an electric heating net is arranged inside the drying table, and one side of the drying table is provided with a secondary conveying belt. By arranging the drying machine and the cooling box, rapid and effective drying can be carried outon the premise of not damping the structure, the straw granules can be cooled in the cooling box after completion, the temperature is rapidly reduced, materials discharge from a discharge outlet can be immediately packaged, and operation is rapid and efficient and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a drying device for straw particles. Background technique [0002] At present, there are various types of drying devices. The dryers have several modes such as belt drying, drum drying, box drying and tower drying. The heat sources include coal, electricity and gas. In the drying process, there are hot air flow type and radiation type, etc. The hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and fully utilizes the heat transfer through heat conduction, convection, and radiation, and directly transfers heat to the material. The moisture of the material is continuously evaporated in the cylinder, and the air-inducing device at the material inlet draws out a large amount of water and wet air to prevent secondary pollution caused by dust discharge. The material is pushed forward by internal spiral stirring, sweeping a...

[0002] At present, there are various types of drying devices. The dryers have several modes such as belt drying, drum drying, box drying and tower drying. The heat sources include coal, electricity and gas. In the drying process, there are hot air flow type and radiation type, etc. The hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and fully utilizes the heat transfer through heat conduction, convection, and radiation, and directly transfers heat to the material. The moisture of the material is continuously evaporated in the cylinder, and the air-inducing device at the material inlet draws out a large amount of water and wet air to prevent secondary pollution caused by dust discharge. The material is pushed forward by internal spiral stirring, sweeping and lifting movement to complete the entire drying process, but the existing dryers are complex in operation and cumbersome in process, and cannot be dried quickly and effectively, and it takes a period of time after drying to be packaged for storage, and the whole process is time-consuming and laborious
