Novel drying device

Abstract

The invention provides a novel drying device, comprising a drying barrel, a cooling barrel and a rotating inner barrel; wherein the rotating inner barrel is sleeved in the drying barrel; a verticallyarranged main shaft is arranged in the rotating inner barrel; the main shaft is fixedly connected with the rotating inner barrel; a plurality of stirring rods are arranged on the main shaft; the sidewall of the drying barrel is sequentially provided with an insulating layer and a heating layer from the outside to the inside of the barrel; the cooling barrel is connected with the drying barrel through a connecting channel; the cooling barrel is located at the lower part of the drying barrel; a horizontally arranged hollow rotating shaft is arranged on the cooling barrel; the hollow rotating shaft is provided with a plurality of air ducts, which communicate with the hollow rotating shaft; the two ends of the hollow rotating shaft pass through the cooling barrel; one end of the hollow rotating shaft is connected with a second motor outside the cooling barrel and the other end of the hollow rotating shaft is connected with the connecting pipe. The novel drying device provided by the invention has uniform drying, and can effectively help fertilizer particles cool after drying.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer production equipment, and in particular relates to a novel drying device. Background technique [0002] Fertilizer is a necessity in the growth process of crops and other plants, which can ensure the nutrients needed for their growth. In the process of fertilizer production, after the fertilizer is granulated, it still contains a large amount of water and steam. If it is directly packaged, it will cause the fertilizer particles to condense into blocks and affect the quality of the fertilizer. In order to ensure that the fertilizer particles themselves have a certain strength and hardness, Fertilizers generally need to be dried. Most of the existing drying devices use hot air to dry. Because it is difficult to control the flow of hot air, the drying effect is unstable, and the dried fertilizer particles cannot be packaged immediately after high temperature, because a large amount of water vapor ...

AI Technical Summary

Problems solved by technology

Most of the existing drying devices use hot air to dry. Because it is difficult to control the flow of hot air, the drying effect is unstable, and the dried fertilizer particles cannot be packaged immediately after high temperature, because a large amount of water vapor will be generated after packaging. The dried fertilizer granules are softened and need to wait for the fertilizer granules to cool before packaging
