Description

Gradient compounding device and method for natural plant source filtering material Technical Field The invention relates to the technical field of preparation of environment-friendly filter materials, in particular to a gradient composite device of a natural plant source filter material and a method thereof. Background The natural plant source filter material is taken as an important component in the field of environmental protection, and is paid attention to in the application of air purification, water treatment and the like due to the advantages of reproducibility, biodegradability, low cost and the like. The material is generally prepared from plant fibers (such as wood chips, straws and the like) through chemical modification, has a porous structure, and can effectively adsorb pollutants. In the prior art, a single formula slurry is adopted to produce the filter material through steps of mixing, forming, curing and the like, but with the improvement of environmental protection requirements, the filter material with a single structure is difficult to meet the requirements of complex application scenes, such as gradient porosity or functional layering (such as combination of a high adsorption layer and a high support layer) so as to improve the filtration efficiency and selectivity. In the traditional process, the preparation of the filter material often depends on step-by-step operation, namely, slurries with different formulas are prepared independently, and then laminated and compounded manually or by simple machinery. This method involves multiple independent devices, such as separate crushers, stirred tanks and forming devices, resulting in process flow fragmentation. In addition, the prior art focuses on the preparation of homogeneous materials, and lacks precise control over gradient composite structures, so that the filter material has limitations in interlayer bonding strength, pore distribution consistency and the like. With the popularization of green manufacturing concepts, an integrated and automated solution is needed in the industry to realize efficient and controllable production of gradient composite filter materials. However, the following drawbacks mainly exist in the prior art: firstly, the existing device adopts a single slurry formula, so that slurries with different porosities or functional characteristics are difficult to prepare in parallel, interlayer mixing is easy to cause by stepwise mixing and manual lamination in the traditional method, gradient effect and selective filtering capability of the filtering material are reduced, for example, when slurries with different formulas are compounded, interfacial separation can occur due to uneven mixing, and the overall performance is influenced; secondly, in the prior art, the steps of crushing, mixing, forming, solidifying and the like are often completed by independent equipment, so that the material transfer time and the energy consumption are increased; Thirdly, the traditional rolling and curing method lacks synchronous control, so that bubbles or uneven thickness of the slurry layer are easy to occur in the forming process, interlayer binding force is weakened, the prior art cannot ensure that the pore structure is controllable, and the filter material is easy to damage in a high-pressure environment, so that the service life is shortened; In view of the above, the present invention provides a gradient composite device for natural plant source filtering material and a method thereof.
