A control method and system for clinker and aggregate divergence pre-measurement

Abstract

The invention discloses a clinker and aggregate divergence expected quantity control method and system. The method comprises the steps that a PLC judges whether the preloaded material type of a vehicle and the material type of a preloaded lane are the same or not, and if the material types are the same, a quantitative feeding machine starts to load materials onto the vehicle; a weighing sensor, aspeed measuring encoder and a speed regulating motor are arranged on the quantitative feeding machine, and the weighing sensor is used for weighing the material weight of the weighing section of the quantitative feeding machine; the speed measuring encoder measures a speed pulse signal of a tail wheel of the quantitative feeding machine; the PLC determines the accumulated loading quantity according to the material weight and the speed pulse signal of the weighing section; the accumulated loading quantity is compared with the preloading buffer quantity, when the accumulated loading quantity reaches the preloading buffer quantity, the PLC controls the speed regulating motor to reduce the rotating frequency of a driving wheel of the quantitative feeding machine; and when the accumulated loading quantity reaches the preloading quantity, the quantitative feeding machine stops loading. According to the clinker and aggregate divergence expected quantity control method and system, the situations of wrong loading, inefficient loading and excessive loading are avoided, and the loading metering accuracy and the loading efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of clinker and aggregate loading, in particular to a control method and system for clinker and aggregate divergence pre-measurement. Background technique [0002] At present, the overloading of automobiles has had a great impact on the loading of clinker and aggregate in cement and mining enterprises from the source. The existing technology is to install a flow valve at the bottom of the material warehouse, and the operator manually controls the flow valve, so that there are phenomena of wrong, under-loaded and over-loaded materials, wrongly loaded materials need to be unloaded, and under-loaded materials need to be refilled. Overloading will unload, and this phenomenon occurs very frequently, which not only causes environmental pollution, but also greatly affects the production efficiency of cement and mining enterprises. Contents of the invention [0003] The object of the present invention is to provid...
