全自动液压制砖机配料控制系统设计

Design of Batching System for Fully Automatic Hydraulic Brick Making Machine

我国粉煤灰在建材制砖方面得到广泛应用。本文结合每次产转24块,年产量0.8亿块的一种三梁四柱式液压制砖机,设计一种由PLC控制的自动配料和输料系统。该配料系统根据粉煤灰物料特点和配料、供料方式,由三个罐子单独装料和称重粉煤灰、水泥和水,由PLC控制配料和输送实现全程自动化操作。同时利用控制系统仿真软件组态王对该设备控制系统进行了控制仿真,保证了控制系统生产安全可靠,配料精确,效率高,提升了企业竞争力。

Fly ash is widely used in brick making of building materials in China. In this paper, on the basis of a three-beam and four-column hydraulic brick making machine with a single output of 24 bricks and an annual output of 80 million bricks, an automatic system to batch and convey the materials controlled by PLC system is designed. According to the characteristics of fly ash, the batching and conveying mode, the system is composed of three tanks to load and weigh the fly ash, the cement and the water separately, and PLC controls the batching and conveying to realize the automatic operation. At the same time, the control system of the equipment is simulated by the control system simulation software, which ensures the safety and reliability of production, the accuracy of batching, and the efficiency of the control system, and improves the firm competitiveness correspondingly.
