AI Technical Summary

Technical Problem

In existing technologies, the material at the bottom and corners of diuron granules is difficult to roll up, resulting in uneven mixing, poor heat reuse, and significant heat loss.

Method used

It adopts an inner and outer spiral structure, combined with a hollow ring and rotating shaft design. The inner and outer spirals are driven to rotate by a high-temperature resistant motor. The material is circulated and mixed between the inner and outer spirals. The dehumidification mechanism and high-temperature water-absorbing and expanding resin are used to treat the evaporated moisture, so as to achieve the reuse of heat and uniform heating.

Benefits of technology

It achieves uniform mixing and rapid drying of materials, reduces the problem of excessively high temperature of materials at the bottom, improves the efficiency of heat utilization, and ensures the uniformity and efficiency of drying effect.

Abstract

The present application provides a kind of diuron granule moisture drying device, it is related to drying device technical field, including drying frame body and quartz heating tube, quartz heating tube is arranged on the inner wall of drying frame body, bottom support is arranged below the inside of drying frame body, the central position of bottom support top is equipped with heat dissipation cylinder, the bottom support top of heat dissipation cylinder outside is rotatably equipped with inner spiral and outer spiral, the diameter of inner spiral is less than outer spiral, hollow ring is arranged on the bottom support between inner spiral and outer spiral, clearance is left between the lower end of hollow ring and bottom support, the inside of drying frame body is equipped with rotating shaft.The slow rotation of inner spiral and outer spiral can lift the material originally located at the bottom to the upper, and drop from the upper end of hollow ring to the bottom, so circulation, not only can realize the mixing of material horizontal direction, but also can realize the mixing of up and down position, avoid the material located at the bottom is always not lifted, cause the problem of the material temperature of bottom to be too high.
