Rotary shaft crusher capable of intelligent overload control and overload control method of rotary shaft crusher

Abstract

The invention provides a rotary shaft crusher capable of intelligent overload control and an overload control method of the rotary shaft crusher. The rotary shaft crusher comprises a PLC (Programmable Logic Controller), a pressure sensor, a hydraulic system, at least two rotary shafts, an intermediate relay and an alternating-current contact, wherein the PLC is provided with a pressure segmentation control module which comprises a pressure detection unit, a main circulating type control section unit, a pressure overload information storage unit and a rotary shaft type control unit. According to the rotary shaft crusher, the defects of the existing similar rotary shaft crushing systems such as a garbage crusher system are improved; an intelligent overload control program is arranged inside the existing rotary shaft crusher, the system pressure is periodically detected in a circulating manner, once materials are excessive or are blocked to be delayed to be crushed, the directions of the rotary shafts can be changed intelligently, so that the mechanical breakage of the system caused by pressure overload due to material blockage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of hydraulic system control, and in particular relates to a rotary shaft crusher capable of intelligent overload control and an overload control method thereof. Background technique [0002] At present, when the rotary shaft crushing system is working, due to the characteristics of the uncertainty of the crushed materials, the load changes too much, and there is a requirement for the rotating shaft to change direction during work; If the pressure is too high, it will be alarmed. Immediately shut down and check manually, which may lead to the shutdown of the entire production line; or directly jump into a single reversing cycle control, which cannot completely guarantee that the pressure of the shaft after the reversing will not be overloaded. If the pressure is too high again Alarm, or can only be manually checked immediately after shutdown, resulting in easy interruption of production continuity, low produc...

[0002] At present, when the rotary shaft crushing system is working, due to the characteristics of the uncertainty of the crushed materials, the load changes too much, and there is a requirement for the rotating shaft to change direction during work; If the pressure is too high, it will be alarmed. Immediately shut down and check manually, which may lead to the shutdown of the entire production line; or directly jump into a single reversing cycle control, which cannot completely guarantee that the pressure of the shaft after the reversing will not be overloaded. If the pressure is too high again Alarm, or can only be manually checked immediately after shutdown, resulting in easy interruption of production continuity, low production output, and more requirements for manpower and material resources, imperfect control of the system, easy to cause the mechanical nature of the system itself destroy
