Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction spraying, in particular to a layered spraying equipment for inorganic fiber ceiling construction. BACKGROUND

[0002] In the field of building decoration, inorganic fiber sprayed ceiling is widely used in large public buildings, industrial plants, underground spaces and other places due to its excellent fireproof, heat-insulating, sound-absorbing and other performances. The traditional inorganic fiber spraying construction mainly relies on manual or semi-automatic equipment, which has many technical bottlenecks and seriously affects the construction efficiency and quality.

[0003] The existing inorganic fiber spraying construction mainly has the following problems. Inorganic fiber materials such as rock wool and glass wool are prone to clumping due to moisture during storage and transportation. However, the traditional spraying equipment lacks efficient crushing and stirring mechanisms, resulting in the presence of clumped fibers when the material enters the spraying system. These clumped fibers can easily clog the spray gun during spraying, causing uneven discharge and affecting the flatness and density of the ceiling coating. In addition, insufficiently dispersed fibers may accumulate or loosen unevenly after spraying, reducing the fireproof and soundproof performance. Most current spraying equipment uses an open feeding method. When adding inorganic fibers, the fiber dust is easily dispersed into the air, not only polluting the construction environment and causing respiratory diseases in workers, but also mixing external dust and impurities into the fibers, affecting the spraying quality. Although some equipment uses a simple dust cover, it still cannot achieve complete sealing and is inconvenient to clean and maintain. In some construction scenarios, in order to improve the adhesion of the inorganic fiber coating, adhesive such as water-based glue needs to be sprayed simultaneously. However, the traditional equipment usually uses a step-by-step spraying method, i.e., spraying fibers first and then spraying glue, or uses a simple mixing nozzle, resulting in insufficient combination of glue and fibers and problems such as delamination and peeling of the coating. In addition, the delivery of glue relies on manual control, making it difficult to accurately adjust the amount of glue and affecting the construction quality. Traditional spraying equipment mostly relies on manual operation, such as manually adjusting the air compressor pressure, controlling the fiber delivery speed, and adjusting the spray gun angle, which not only has high labor intensity but also makes it difficult to ensure uniform spraying. In the layered spraying process, different fiber layers require different spraying parameters such as thickness and density. However, the existing equipment lacks an intelligent control system, making it difficult to accurately achieve the requirements of layered spraying, resulting in low construction efficiency and high rework rate.

[0004] To solve the above problems, some improved spraying equipment adopts the following technical scheme: a stirring blade is arranged at the feed inlet to reduce fiber clumping, but such structure usually has insufficient stirring intensity and cannot completely break up the fiber clumps, and is prone to wear after long-term use; a openable hopper is used to reduce dust overflow, but manual intervention is still required, and the sealing performance is insufficient; the structure of the spray head is improved to mix the glue and the fiber at the outlet, but the mixing uniformity is still not ideal, and the glue pipe is prone to blockage, these improvement schemes still have limitations and cannot fundamentally solve the problems of fiber dispersion, pollution control, glue-fiber mixing and automatic construction. Therefore, a new type of inorganic fiber spraying equipment is urgently needed, which can realize efficient crushing, sealed feeding, intelligent spraying and precise mixing of glue and fiber to meet the high standard requirements of modern building construction.
