摘要

为满足泡沫混凝土制备过程中对泡沫密度和泡沫直径的各种要求,设计了一种由送风系统、送液系统、发泡装置和控制系统组成的可调式发泡机。通过控制发泡液流量来调节气液比,从而达到调节泡沫密度的目的。采用可调单泡管结构,通过调节发泡管中发泡介质的填充密度,实现对泡沫密度和孔径的控制。以单片机作为数字处理核心,通过RS485接口建立单片机与变频器之间的通信,从而实现可调发泡机工作过程中的自动控制。实验结果表明,该机的发泡过程稳定、高效,泡沫密度和泡沫直径易于调节和控制,提高了产品的可用性。

Study on the Design of an Adjustable Foaming Machine
An adjustable foaming machine that consisted of air feeding system, liquid feeding system, foaming device, and control system was designed to satisfy various demands on foam density and foam diameter in the preparation of foam concrete. The air-liquid ratio was adjusted by controlling the foaming liquid flow, and the adjustment of foam density was achieved. An adjustable single-foam tube structure was adopted to realize the controls of foam density and pore size by adjusting the packing density of the foaming medium in the foaming tube. By using the single chip as the digital processing core, the communication between single chip and frequency converter was established through the RS485 interface, thereby realizing the automatic control in the working process of the adjustable foaming machine. The experimental result indicated that the foaming process of this machine was stable and highly efficient, and foam density and foam diameter were easy to adjust and control, which improved the usability.
