Problems solved by technology

[0023] The object of the present invention is to provide a feeder with a bionic shark skin shield scale structure and drag-reducing particles and a manufacturing method, and copy the bionic shark-skin scale structure and drag-reducing particles on the spiral blade to reduce or solve the problem of the feeder. When conveying biomass powder at medium and high temperature, the biomass powder will stick into agglomerates and adhere to the transportation pipes, resulting in large feeding resistance, wear, deformation, and damage of the feeding mechanism, and the power of the feeding motor is large. Slow speed, easy to generate wear noise, and even burn the conveying motor, in order to achieve the effect of reducing drag and noise, prolonging the life of the feeding mechanism, and ensuring smooth feeding

[0069] The biomass briquettes are formed, the particle size of the wood powder is controlled at about 30 mesh, and a single-pipe screw feeder with a shaft is used for feeding. In addition, in a self-made vacuum hot press, a polymethyl methacrylate (PMMA) plate was used as a substrate, and 150×300mm shark skin scales were spread on it with the face down and flattened with a plate supplemented by an air cushion; the temperature was raised under vacuum conditions. To the glass transition temperature (Tg) of PMMA (Tg) 105°C and kee...

Embodiment 3

[0072] Such as Figure 4 As shown, in this embodiment, the shield scale structure includes staggered distribution of shield scales A8 and continuous distribution of shield scales B9, drag reducing particles A4 are distributed on the surface of shield scales A8, and drag reducing particles B5 are distributed between shield scales A8 ; Drag-reducing particles C6 are distributed on the surface of the shield scale B9, and drag-reducing particles D7 are distributed between the shield scales B9.

[0073] In some rural areas, many waste straws and agricultural and forestry wastes in the fields are burned on site, which pollutes the environment and wastes resources. Therefore, they can be further processed to obtain biomass scraps, mixed with corn stalks and branches, and the length of scraps is about Below 5mm, equivalent diameter below 2mm, use shaftless screw feeder for feeding. Using high-precision electron microscope and scanning electron microscope to observe the biological tem...

Abstract

The invention belongs to the field of application of engineering bionics techniques, and particularly relates to a feeder provided with a bionic sharkskin placoid scale structure and resistance reducing particles and a manufacturing method. The feeder comprises a feeding machine, the bionic sharkskin placoid scale structure and the resistance reducing particles, wherein the bionic sharkskin placoid scale structure and the resistance reducing particles are distributed on the surface of blades of the feeding machine. The manufacturing method is characterized in that the surface of the sharkskinis scanned to obtain the placoid scale structure which is copied to the surfaces of the blades. With the adoption of the feeder, the frictional force between the blades of the feeding machine and materials in the conveying process can be effectively reduced.

Description

technical field [0001] The invention belongs to the application field of engineering bionic technology, in particular to a feeder with a bionic sharkskin shield scale structure and drag-reducing particles and a manufacturing method. Background technique [0002] In recent years, energy and related environmental issues have become one of the most concerned hotspots in the world, and all countries are actively seeking feasible solutions to coordinate energy and environment based on their own national conditions. my country needs to consume a large amount of fossil energy every year, and it has shown an increasing trend year by year in recent years. According to the statistics of the National Energy Administration, my country's total energy consumption in 2016 was about 4.36 billion tons of standard coal, of which raw coal consumption was about 2.7 billion tons of standard coal. While supporting the rapid economic and social development, fossil energy has also brought serious ...
