AI Technical Summary

Technical Problem

The existing air distribution structure of the grate cooler cannot be flexibly adjusted according to the real-time distribution of clinker, resulting in insufficient air volume in the inlet area, slow cooling rate, low heat recovery efficiency, and excessive air volume in the middle and outlet areas, which increases energy consumption.

Method used

The system employs a combination of adjustment and drive mechanisms, using an eccentric wheel and spring to slide the baffle, thereby adjusting the ventilation cross-sectional area of ​​the air inlet duct in real time. Combined with a limiting mechanism, it ensures precise and controllable airflow distribution.

Benefits of technology

It enables dynamic adjustment of airflow distribution based on clinker distribution, improving cooling efficiency, reducing energy waste, and ensuring the accuracy and stability of airflow regulation.

Abstract

This utility model discloses an air distribution structure for a grate cooler, relating to the field of grate cooler technology. It includes a grate cooler body with two air inlets on one side. Each air inlet has an air inlet pipe fixedly connected to its interior. One end of each air inlet pipe is fixedly connected to a fixing plate. One end of the fixing plate is fixedly connected to a U-shaped pipe, and a fan is mounted on one side of the U-shaped pipe. The fixing plate has a cavity inside, with two mounting holes on both sides of the cavity. This utility model utilizes the eccentric wheel and spring of an adjusting mechanism to drive a baffle to slide along a sliding rod, thereby changing the ventilation cross-sectional area of ​​the two air inlets in real time and achieving on-demand airflow distribution. To address differences in clinker distribution, the airflow can be increased in the inlet area to accelerate the cooling of high-temperature clinker; the airflow can be reduced in the middle and outlet areas to avoid energy waste.
