The invention discloses a foam pressure filling device used for a hollow material. The foam pressure filling device comprises a foaming liquid device, a high-pressure gas conveying device, a foaming cavity, a pressure filling device and a controller, wherein the foaming liquid device and the high-pressure gas conveying device are separately connected with the foaming cavity; the pressure filling device comprises a pressure filling tank, a gas release valve arranged on the top of the pressure filling tank, and a pressure acquiring device which is arranged on the top of the side surface of the pressure filling tank; a foam outlet of the foaming cavity communicates with a foam inlet of the pressure filling tank; a pipeline for enabling the foaming cavity to communicate with the pressure filling cavity is sequentially equipped with a flow meter and a foam valve; and a controller is separately in signal connection with the foam valve, the gas release valve, the pressure acquiring device andthe flow meter. The invention further provides a foam pressure filling method. The whole control process is simple to operate, monitors pressure and flow on line to automatically regulate the foam valve and the gas release valve, reduces manual operation strength and influences of human factors, and ensures foam filling of an air material to be sufficient and uniform.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a pressure-filled foam device and method for hollow materials. Background technique [0002] Hollow materials, such as sintered hollow bricks and hollow ceramsite, have a certain amount of interconnected voids inside, so they are light in weight and have low thermal conductivity, and have been widely used in energy-saving buildings. However, these hollow materials also have certain shortcomings. For example, the existence of interconnected voids makes the material less compact, and when there are many internal voids, it will cause air flow and increase the thermal conductivity, thereby reducing the heat preservation and energy saving effect. [0003] In order to improve the deficiencies of the hollow material, it can be considered to fill the internal void of the hollow material with foam, so as to increase the overall compactness, further reduce the flow of air in the intern...
