Abstract

The invention relates to the technical field of grate coolers, in particular to a grate cooler servo hydraulic driving control system device. The device comprises a control machine, a servo driver, a servo motor, an oil tank, a supercharger, an oil pump, a backflow mechanism, a plurality of pressure controllers and a plurality of pressure outlets corresponding to the pressure controllers, wherein a PLC (programmable logic controller) is arranged in the control machine, the servo driver is connected with the control machine and conducts signal interaction with the servo motor through an encoder, the servo motor is connected with the oil pump, and the oil pump is connected with the oil tank. According to the grate cooler servo hydraulic driving control system device, the multiple pressure controllers have constant pressure output, output pressure is more stable, all the pressure controllers are mutually independent, and the working efficiency is high; the backflow mechanism can recycle pressure-controlled medium liquid to avoid resource waste; and linked multi-range heat dissipation mechanisms in an element can ensure the normal operation of the equipment element and avoid high-temperature damage.

Description

technical field

[0001] The invention relates to the technical field of grate coolers, in particular to a servo hydraulic drive control system device for grate coolers. Background technique

[0002] The grate cooler is an important host equipment in the clinker firing system of a cement plant. Its main function is to cool and transport cement clinker, and at the same time provide hot air for the rotary kiln and calciner. It is the main heat recovery system for the firing system. Equipment, grate cooler is a kind of quench cooler. After the clinker enters the cooler from the kiln, a material layer of a certain thickness is laid on the grate plate, and the cold air blown in passes through the moving material layer on the grate bed in a direction perpendicular to each other to quench the clinker. The clinker is quenched from 1300-1400 โ„ƒ to below 100 โ„ƒ in a few minutes. The traditional grate cooler is divided into three types: rotary type, vibration type and push type. However, ...
