AI Technical Summary

Technical Problem

In existing technologies, the rapid evaporation of moisture from coal at high temperatures leads to a high risk of spontaneous combustion, increasing the likelihood of fires. Furthermore, traditional drying methods are inefficient and costly, failing to meet the needs of large-scale production.

Method used

A mechanical vertical kiln calcination device for coal gangue and kaolin is adopted. The coal is dried by conveyor belt design and low temperature dryer convective hot air. Combined with a filtration mechanism to filter out impurities in the exhaust gas, the risk of spontaneous combustion is reduced and safety is improved.

Benefits of technology

This technology enables efficient coal drying, reduces energy consumption, minimizes environmental pollution risks, and improves the safety and production efficiency of the equipment.

Abstract

This utility model relates to the field of coal processing technology and discloses a mechanical vertical kiln calcination device for coal gangue and kaolin. The device includes a calcination kiln, with a feed pipe fixedly connected to the top left side of the kiln. Fixed plates are fixedly connected to the front and rear ends of the inner top of the kiln. Two conveyor belts are fixedly connected between adjacent fixed plates. Connecting rods are fixedly connected to the rear left end of the top conveyor belt and the rear right end of the bottom conveyor belt. The rear ends of both connecting rods penetrate the rear fixed plates and the calcination kiln. Support plates are fixedly connected to the lower right and middle left ends of the calcination kiln. In this utility model, a motor drives the connecting rods to rotate, causing the conveyor belts to operate. The coal first moves to the right and then to the left of the lower conveyor belt. A low-temperature dryer dries the coal with convective hot air, and the generated gas is discharged through the top exhaust pipe, thereby reducing energy consumption and improving the safety of the device.
