AI Technical Summary

Technical Problem

The existing technology suffers from the problem of temperature gradient caused by directly laying materials flat and the poor temperature control accuracy of traditional rotary kilns. In particular, the internal temperature difference of the material is large during high-temperature heat treatment, resulting in uneven heat treatment quality.

Method used

The material heat treatment fixture adopts a rolling conveyor type. The material inside the cylinder is rolled and turned by a horizontal rotating conveyor mechanism. Combined with multi-section kiln segmented temperature control, the cylinder is equipped with bearings and limit plates to achieve uniform heating and temperature difference control of the material. The motor drives the adjustment of conveying speed and turning frequency.

Benefits of technology

It achieves uniform heating of the entire material, reduces temperature difference, improves heat treatment effect and batch stability, enhances temperature control accuracy, extends equipment life, and adapts to the process requirements of different materials.

Abstract

This invention discloses a rolling conveyor-type material heat treatment fixture, including a material cylinder for carrying materials, a multi-section kiln, and a horizontal rotary conveyor mechanism that penetrates the kiln or extends into the heat treatment area of ​​the kiln. The multi-section kiln can be combined and connected for segmented temperature control. The horizontal rotary conveyor mechanism includes two sets of opposing sprocket and chain drive units and several second push rods connected between the two sets of sprocket and chain drive units and moving with the chain. The material cylinder moves along a predetermined path and rolls around its own axis under the push of bearings and the constraint of limiting plates, causing the material inside the cylinder to tumble and shift during the heat treatment process. Materials are filled into the material cylinder and placed entirely into the kiln or carbonization furnace. The horizontal rotary conveyor mechanism drives the material cylinder to continuously roll and tumble, causing the material to continuously shift and mix during the heat treatment process, achieving uniform heating throughout the entire area, effectively balancing the temperature differences inside the material cylinder, and significantly improving the overall heat treatment effect and batch stability of the material.
