Intelligent control system of hydraulic gyratory crusher

Abstract

The invention provides an intelligent control system of a hydraulic gyratory crusher and belongs to a crusher control system. According to the intelligent control system, multiple operation indexes including the motor current, the size of a tight-side discharging hole, the thickness of a lining plate, the material level, the workload, the oil supply pressure, the oil supply temperature, the oil return pressure, the oil return temperature, the flow and the like are monitored by virtue of an ampere meter, a position sensor, a pressure meter, a thermometer and a flow meter in the hydraulic gyratory crusher in real time, are intelligently controlled by virtue of a PLC (Programmable Logic Controller) technique and are fed back to a visual interface in real time; a hydraulic lubricating system is controlled by virtue of a heater, a cooler, a filter, a stroke switch, a valve and the like to heat and cool an oil path or release and lock the oil path, so that the information is manually monitored in real time, multiple devices can be simultaneously controlled, and manpower and material resources are saved; by monitoring and analyzing the various operation parameters of the hydraulic gyratory crusher in real time, various risks and measures are omitted, and unattended crushing work is guaranteed.

Description

technical field [0001] The invention relates to a crusher control system, in particular to an intelligent control system for hydraulic gyratory crushers. Background technique [0002] Gyratory crusher is a relatively commonly used crusher series, also known as vertical composite crusher or composite crusher, which is the key equipment in the coarse crushing and sand making production line in the crushing production line. By using the revolving movement of the crushing cone in the cone cavity in the shell, it can squeeze, split and bend the material, and it is a large-scale crushing machine that roughly crushes ores or rocks of various hardness. The upper end of the main shaft with the crushing cone is supported in the bushing in the middle of the beam, and its lower end is placed in the eccentric hole of the shaft sleeve. When the shaft sleeve rotates, the crushing cone moves eccentrically around the center line of the equipment, so its crushing action is continuous, so the...
