A solid material drying system

Abstract

The invention discloses a solid material drying system, which includes a drying tower and a closed endless conveyor belt located at the bottom of the drying tower, the solid material enters the drying tower through the conveyor belt, and the first air flow is passed The bottom end of the tower passes through the conveyor belt and moves towards the top of the drying tower; wherein, the side wall of the drying tower is provided with several openings, and the second airflow moves from the inside of the drying tower to the outside of the drying tower, so A baffle plate capable of closing the opening is arranged inside the drying tower close to the top of the opening, and the baffle plate is hinged to the side wall of the drying tower. The invention is suitable for drying solid materials, especially granular or bar-shaped fertilizers. It can be used for drying various types of solid materials efficiently and universally, and it can dry solid materials with different sizes, moisture content, quantity, and dryness requirements. dry.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a solid material drying system. Background technique [0002] Solid materials, such as granules or bar-shaped fertilizers, have a large moisture content during the preparation process. In order to make the materials easy to store, transport and use, or to meet the needs of further processing, the excess water needs to be removed. The existing material drying system generally achieves the purpose of drying through the falling of the material, the upward movement of the airflow, and the relative movement of the two, but through the falling of the material gravity, the material needs to be put in at one time or intermittently, and too much at one time will easily cause uneven drying. , Repeated intermittent input is likely to cause subsequent material accumulation, which is not conducive to continuous production operations, and the existing drying equipment is prone to unsat...
