Integrated type screening drying device

Abstract

The invention discloses an integrated type screening drying device. The integrated type screening drying device comprises a shell, a shell is of a cavity structure, a drying room and a cooling room are arranged in the shell, a partition board is arranged between the drying room and the cooling room, a feeding pipe communicating with the drying room is arranged on the top end of the shell, a stirring mechanism is arranged in the drying room, a conveying pipe is arranged at the bottom end of the drying room, a first packing auger shaft is arranged in the conveying pipe, a first driving motor isarranged on the side, extending to the shell, of one side of the first packing auger shaft, a fan is arranged on the top end of the first driving motor, the output end of the fan is provided with a gas transportation pipe extending into the conveying pipe, the partition board is of a cavity structure, and a first rotating shaft is arranged in the partition board. The device has the beneficial effects that chemical fertilizer in the drying room is evenly stirred, the chemical fertilizer can be rapidly and evenly dried, the surface temperature of the dried material is reduced, dust and powder included in the material particle are separated, the chemical fertilizer is clear grain by grain, the screening effect is better, the device is more attractive, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of production, in particular to an integrated screening and drying device. Background technique [0002] In the production of materials, it is necessary to dry the granulated materials to form dry solid particles, which are convenient for storage and transportation. During the drying process, the materials need to be raised by the lifting board to form a material curtain to exchange with hot air. The material is dried to avoid particle sticking or local overheating. There are many dryers that use hot air to dry. It cannot be packaged immediately, otherwise a large amount of water vapor will be generated after packaging to soften the dried particles, and it is necessary to wait for the particles to cool before packaging, which will affect the efficiency of packaging. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at...
