Intelligent control system of foam concrete preparation machine and control method of intelligent control system

Abstract

The invention discloses an intelligent control system of a foam concrete preparation machine. The intelligent control system comprises a human-computer interface component, a central controller component, a raw material metering component, a raw material power control component, a raw material flow monitoring component and a fluid power output control component. The human-computer interface component is connected with the central controller component. The central controller component is in signal connection with the raw material metering component, the raw material power control component, theraw material flow monitoring component and the fluid power output control component. An automatic control manner of intelligent information processing, intelligent information feedback and intelligent control decision making is adopted, only technical parameters such as the foam concrete wet density, the foam density, the mix proportion and the yield need to be input during use, after equipment is started, a control system automatically controls feeding, metering and stirring of raw materials, the output quantities of neat paste, a foaming agent, foaming agent dilution water and compressed gas are dynamically adjusted, and electronic metering, automatic control and intelligent adjustment are fully realized.

Description

technical field [0001] The present invention relates to the technical field of mechanical intelligence, and more specifically relates to an intelligent control system of a foam concrete preparation machine and a control method thereof. Background technique [0002] Foamed concrete preparation machine (preparation machine for foamed concrete) is a special equipment for the production of foamed concrete, foamed lightweight soil, foamed lightweight soil, foamed cement, and foamed concrete (hereinafter collectively referred to as "foamed concrete"), and is used for on-site pouring Construction or pouring of foamed concrete products. The composition of the foam concrete preparation machine includes: raw material equipment and conveying device, mixing and pulping device, foaming device, foam mixing device and foam concrete slurry conveying device and other parts. [0003] The foaming process used by the foam concrete preparation machine to produce foam concrete is usually physica...

Problems solved by technology

[0005] 1. In the process of on-site debugging such as foam density and foam concrete wet density, it needs to be adjusted several times according to the prepared foam concrete to achieve the specified technical indicators, which takes a long time and wastes raw materials seriously;

[0006] 2. The density difference of foam and foam concrete slurry at different time points during the continuous production of the foam concrete preparation machine reflects the continuous uniformity of the foam concrete slurry produced by the preparation machine, and the foam density and foam concrete slurry in the actual construction production process The density difference rate is large, which affects the performance quality of foam concrete

[0007] The applicant conducted in-depth research and found that due to differences in raw materials, technical requirements, and on-site environmental factors, during the working process of the foam concrete preparation machine, the measurement of raw materials was inaccurate, and the output flow among the clean slurry, foam agent, foam agent dilution water, and compressed gas Interaction, coupled with the interference of external factors such as pipeline pressure changes, the output flow of each component is prone to large fluctuations, and the output of each component cannot be dynamically adjusted in real time and accurately to achieve a dynamic balance.
