Steady flow cooler

Abstract

The invention discloses a steady flow cooler, which relates to the steady flow cooler for cooling and conveying high-temperature cement clinker and the like. The steady flow cooler comprises a bracket, a fixed grate bed and a movable grate bed which are engaged on the bracket, wherein the fixed grate bed and the movable grate bed are provided with an air supply device respectively; a drive device and a guide device are arranged below the movable grate bed; the fixed grate bed has a box-type structure and is partitioned into a plurality of units by partition boards, a front grate plate arranged obliquely downwards is arranged above each unit, a plurality of adjacent front grate plates form an area, an independent air supply device is arranged below each area, and the air pressure and the air quantity of the each air supply device are controlled by a control unit; and the movable grate bed comprises a plurality of movable longitudinal beams arranged on the bracket and driven to run by the drive device and the guide device, a plurality of independent rear grate plates are arranged on each movable longitudinal beam, and an air supply device with adjustable air pressure and air quantity is arranged below the rear grate plates respectively. The steady flow cooler greatly improves the cooling efficiency and the cooling quality of the cement clinker.

Description

technical field [0001] The invention relates to a steady-flow cooler for cooling and transporting high-temperature cement clinker. Background technique [0002] As an important main equipment of the clinker burning system in a cement plant, the cooler is responsible for multiple functions such as cooling, heat recovery, transportation, and crushing of high-temperature red-hot clinker. With the gradual improvement of modern new dry-process cement production technology, the production scale is developing towards large-scale development. One of the key factors is the large-scale equipment and the application of high-tech, and the cooling machine with high efficiency, energy saving and reliable operation has become a guarantee. The whole system has strong production capacity, low energy consumption, high operation rate and a very important factor for the stable operation of the system. [0003] The fixed grate bed at the hot end of the domestic traditional cooler is to install ...

AI Technical Summary

Problems solved by technology

The best cooling air distribution cannot be achieved, and the best cooling effect cannot be achieved with the least cooling air

At the same time, the cooler drives the movable grate plate to push the material forward at the same time through the movable grate beam. It cannot dynamically push the material according to the cooling speed, cooling effect and material layer distribution, which affects the overall cooling effect and cooling efficiency of the cooler.
