Abstract

The invention provides a powder ash material weighing system and a weighing method. The powder ash material weighing system comprises at least two pieces of material weighing equipment and a control device, wherein the control device is connected with each piece of material weighing equipment; different pieces of material weighing equipment are used for weighing material with different precisions; and the control device is used for sending weighing signals with different precisions according to the expected calculated value of powder ash material and the calculated value after powder ash material is weighed, and for driving start-up and closing of different pieces of material weighing equipment according to the weighing signals with different precisions. According to the invention, the control device is used for controlling the at least two pieces of material weighing equipment with different precisions, so that precise weighing of powder ash material is further realized when rough weighing is realized, the weighing efficiency is high, and therefore, high-precision and high-efficiency weighing of material is realized.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a weighing system and method for fly ash materials in the technical field of concrete mixing. Background technique [0002] At present, in the construction machinery industry, metallurgical industry and packaging industry, conveying devices such as cement, fly ash, ore powder are weighed at a single speed. Even if the measurement accuracy is optimized, it is not fine enough. [0003] Take the concrete mixing station as an example. The concrete mixing station is the most frequent equipment for weighing cement, fly ash, mineral powder and other materials. It is mainly used to complete the production of ordinary concrete and special concrete. Among them, special concrete is mainly used in my country's heavy-duty railways and high-speed railways. In addition to the characteristics of high grades, special concrete requires particularly high precision. [0004] However, ordinar...
