Problems solved by technology

However, this method can only be detected after arching occurs in the powder silo and triggers the arch breaking procedure. At this time, the material is already unsmooth, which affects the speed and performance of concrete production.

Abstract

A control method for powder material transportation in concrete production, including: (1) recording and storing the storage time and humidity of different powder materials; (2) for different powder materials, determining the first threshold and the second Threshold; (3) When preparing concrete, calculate the storage time of different powder materials currently input into the powder silo and the integral value of humidity; (4) According to the storage time of the powder and the integral value of humidity, determine whether to use powder The silo is arch broken. Through the control method for conveying powder material for concrete production in the present invention, the production cost can be reduced, and the production efficiency and quality of concrete can be improved.

Description

technical field [0001] The invention relates to a concrete production process, in particular to a powder conveying control method for concrete production. Background technique [0002] Powdered materials used in concrete production include cement, fly ash, limestone, mineral powder, etc. When working, firstly fill cement or other powder into the silo, open the discharge door, the powder will flow into the screw conveyor through the gate, and then be continuously transported to the powder weighing hopper for measurement. [0003] Because the powder itself has strong water absorption, the surface of the particles is hydrated after being absorbed by moisture, the adhesion is greatly increased, the fluidity is weakened, and it is easy to arch or even agglomerate. In production, the problem that powder materials are easy to enter the warehouse and difficult to exit the warehouse often occurs, and the powder materials with poor fluidity and high water content are more difficult t...
