Description

Technical Field

[0001] The invention relates to the technical field related to foaming, in particular to a modular foaming station. Background Art

[0002] At present, the foaming station equipment and pipeline components used in paper-faced gypsum board products are numerous and fragmented, the subsystem equipment and components are mixed and installed together, and the system needs to be assembled on site. The above reasons lead to the existing foaming stations having the disadvantages of poor adaptability, large equipment size, complex system pipelines, numerous and fragmented equipment and pipeline components, inconvenient transportation, complicated and inflexible installation work, inconvenient maintenance, and backward system standardization work. In addition, the current foaming stations generally use a single-pole traditional foaming pump and a single foaming liquid metering system, which is inconvenient to use when compounding the foaming liquid.

[0003] In addition, due to the complexity of the system pipelines and the large number of redundant components, the system adjustment response speed is not ideal, the adaptability to different production speeds is also poor, and the foam quality is unstable, resulting in unstable quality of paper-faced gypsum board products. Problems such as these still exist. In response to the above problems, this application is proposed. Summary of the invention

When each module is used, it only needs to connect the subsystems with pipes, and it can be quickly put into use, thus achieving the goals of system modularization, small size, convenient transportation, simple and flexible installation, and easy use.
