Material feeding control method, device, system and machine-made sand production line equipment

Abstract

The invention discloses a feeding control method, device and system for machine-made sand and a machine-made sand production line device so as to prolong the service life of the machine-made sand production line device and improve the production safety. The feeding control method comprises the steps that the load rates of single machine devices of the machine-made sand production line device are obtained; and when the load rate of at least one single machine device is not smaller than the corresponding early warning load rate, the feeding flow of a feeding belt is controlled to be reduced. Through the scheme, the load rates of the single machine devices can be controlled and adjusted to be smaller than the corresponding early warning load rates, accordingly, safety accidents caused by the too high device load rates are avoided, and on the other hand, the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of machine-made sand production, in particular to a material feeding control method, device, system and machine-made sand production line equipment for machine-made sand production. Background technique [0002] Since natural sand is non-renewable, for the protection of the environment and resources, national and local governments have issued regulations and policies that strictly restrict or prohibit the mining of natural sand. In my country, the amount of construction aggregate is quite huge, and the use and promotion of machine-made sand has become an inevitable trend. [0003] Machine-made sand production line equipment has also developed rapidly in recent years, and has a complete range, safety and stability. As an important part of the machine-made sand production line, the feeding system for machine-made sand production determines the output of the machine-made sand production line equipment, and is ...

AI Technical Summary

Problems solved by technology

[0004] The stand-alone equipment of machine-made sand production line equipment has high power, complicated start-up, various start-up methods, and changeable process flow. At present, machine-made sand production line equipment is basically controlled manually or semi-automatically, and the degree of intelligence is not high.

[0005] The defect of the existing feeding control system is that due to the different types and fineness modulus of raw materials, the actual feeding flow rate often differs greatly from the expected feeding flow rate. Faults may occur due to being overwhelmed, which will affect the service life of the equipment and even cause safety accidents
