Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprayer technology, and in particular to a sprayer for coating building materials. Background Technology
[0002] Building materials are subjected to wind, sun, rain, wear and corrosion over a long period of time, and the surface is often the first to be damaged. In order to extend the service life of building materials, it is necessary to spray the surface of the materials.
[0003] A search revealed that Chinese patent CN202320333431.4 discloses a mixing spraying device for manufacturing lightweight building materials. This device improves work efficiency by setting up a rotating component that drives the operating table to rotate via a motor, thereby rotating the lightweight building materials. At the same time, by setting up an adjustment component that drives the threaded rod to rotate via a primary cyclone separator and moves the spray head left and right, the spraying becomes more uniform and easier to use.
[0004] The above-mentioned technical solution has the following drawbacks. Although such building material surface sprayers can adjust the nozzle and building material through adjustment components to enable rapid spraying of building material surfaces, in actual use, the sprayed paint scatters and volatile organic compounds are directly emitted, affecting the working environment and worker health. To improve environmental protection and collect and treat excess paint, a building material surface sprayer is proposed. This sprayer is equipped with a wide spray pipe, and the uniformly arranged paint nozzles are suitable for spraying panel building materials. It is equipped with a filtration and recovery module to perform multi-stage filtration of spraying waste. The primary cyclone separator can quickly separate large paint particles and dust, the HEPA high-efficiency filter can capture particles larger than 0.3μm, the activated carbon-VOC catalyst layer can adsorb and decompose volatile organic compounds, and a centrifugal separator can separate the recovered paint from impurities, allowing it to be recycled back into the storage tank.
[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
