Continuous preparation device and process of water-collecting net surface with bionic spider silk structure

Abstract

The invention discloses a continuous production device and process of water-collecting meshes with bionic cobweb structures and belongs to the technical field of chemo-bionics. The device comprises a push-in type positioning table, a conveying guide rail, a high-pressure spraying chamber, a drying chamber, a primary raw material tank, a secondary raw material tank, a cleaning stock solution tank and an air compression pump, wherein the push-in type positioning table is located on the conveying guide rail and fixes a to-be-sprayed mesh, the outlet of the primary raw material tank and the outlet of the cleaning stock solution tank are respectively connected with the inlet of the secondary raw material tank through pipelines, the outlet of the secondary raw material tank is connected with the high-pressure sprayer of the high-pressure spraying chamber through a pipeline, and the air compression pump is connected with the high-pressure sprayer through a pipeline. The continuous production device is capable of efficiently producing the even-structured bionic water-collecting meshes in a large-batch manner and extremely high in practical application value.

Description

technical field [0001] The invention belongs to the technical field of chemical bionics, and in particular relates to a continuous preparation device and a preparation process of a water-collecting net surface with a bionic spider silk structure. Background technique [0002] According to WHO statistics, only 0.007% of the world's water can be used directly for human consumption. Water shortage has become the normal state of people's life in many areas, and human beings are also trying various methods to obtain usable water resources. Fog contains a lot of water, and human production and life also produce a large amount of atomized water, such as thermal power plants. In addition, heavy fog weather also brings many troubles to human production and life, so how to efficiently collect fog has become a hot topic. [0003] Traditional water-collecting materials are generally hydrophilic fabrics or metals with good thermal conductivity. For example, in order to develop fog wate...

Problems solved by technology

However, the existing water collection technology has the defects of low efficiency, high water collection cost, unfriendly environment, and low production efficiency of water collection fiber, which cannot meet the urgent demand for water resources in the vast water shortage areas.

[0004] At present, through the efforts of the research group of Professor Zheng Yongmei of Beihang University, the industrial production of water-collecting fibers has been realized in the direction of bionic water-collecting. After simple weaving, the fibers can realize single-pass 6 % water collection performance, which is much higher than the 2% water collection rate of the traditional Rachel mesh surface, but there is a problem of bionic water collection fibers that mechanized weaving destroys heterogeneous structures. In the prior art, continuous and industrialized preparation of water collection is required. The web problem still exists
