Multi-level hot-air drying system

Abstract

The invention relates to a multi-level hot-air drying system. The multi-level hot-air drying system comprises a primary surface drying device, an in-depth surface drying device and a solidified drying device; the primary surface drying device comprises a material conveying belt, a first hopper is arranged at the loading end of the material conveying belt, a first hot-air device is arranged above the material conveying belt, and the air intake of the first hot-air device is connected with a hot-air main pipe; the in-depth surface drying device comprises a material platform, a second hopper is arranged at the loading end of the material platform, a second hot-air device is arranged above the material platform, a polarization mechanism is arranged at the outer side wall of the material platform, and the periphery of the polarization mechanism is hung on an external arranged bed frame; the solidified drying device comprises a roller, the two ends of the roller are rotatably connected with a feeding box and a discharging box respectively, a supporting ring is arranged on the outer side wall of the roller, a supporting device is arranged at the bottom end of the supporting ring, and a driving mechanism is arranged on the supporting device; the motors in the material conveying belt, the polarization and the driving mechanism are all connected to a distribution box. The multi-level hot-air drying system has the advantages that the output can be controlled and the efficiency is high; the multi-level hot-air drying system cannot be influenced by the surroundings.

Description

technical field [0001] The invention relates to a production equipment of colored silicon crystal sand, in particular to a multi-stage hot air drying system composed of multiple drying equipments. Background technique [0002] One step in the production process of colored sand and silica crystal sand is to dry the colored sand. The traditional method is to lay the artificially dyed colored sand on the ground and let it dry naturally. The thickness is 1-6cm. This method is inefficient. The building ground can only be dried once a day for sand mining, which takes up a large amount of land area and requires a lot of labor, high cost, high requirements on the environment, and low moisture in the air. This method is especially not suitable for rainy places. . Contents of the invention [0003] The purpose of the present invention is to provide a multi-stage hot air drying system, which has the advantages of controllable output, no environmental influence and high working effic...
