Problems solved by technology

[0014] The purpose of the present invention is to provide a feeder with a bionic shark skin shield scale structure and a manufacturing method thereof. The bionic shark skin scale structure is copied on the spiral blade of the screw feeder to reduce or solve the problem of the screw feeder. When conveying materials with high viscosity, easy agglomeration and poor fluidity, there will be material adhesion to the transportation pipe fittings, resulting in large feeding resistance, wear, deformation and damage of the feeding mechanism, high power of the feeding motor, slow feeding speed, and easy to produce Abrasion and noise, even burning of the conveying motor and other problems, in order to achieve the effect of reducing drag and noise, prolonging the life of the feeding mechanism, and ensuring smooth feeding

Embodiment 1

[0046] The present embodiment provides a kind of spiral blade with the processing design method of bionic shark skin shield scale structure, and it comprises the following steps:

[0047] Step 1, prepare the shark shield phosphorus biological template: intercept the trunk epidermis of blue shark shark skin (fresh shark skin that can be directly purchased from the seafood market) of 50 mm × 50 mm, peel off the subcutaneous tissue of the trunk epidermis, and use a mass concentration of 3 Washed with ~6% phosphate aqueous solution, peeled off the subcutaneous tissue to obtain shark scute tissue; fixed the cleaned shark scute tissue in 25% glutaraldehyde aqueous solution at 5 ℃ for 20-30 h, and then Gradient dehydration was carried out with ethanol solution with gradually increasing volume fraction; the edge of the dehydrated shark scute tissue was fixed with tooling to prevent warping during the drying process, and then the flattened and fixed shark scute tissue was placed in a dr...

Embodiment 2

[0052] In a briquette preparation plant, pulverized coal is used as the material to be conveyed, and a shaft double-tube screw feeder is used for feeding. Firstly, the shark shield scale structure template was prepared. In a self-made vacuum hot press, a polymethyl methacrylate (PMMA) plate was used as a substrate, and a 150 mm × 300 mm tiger shark skin scale was laid face down on it and assisted by a plate. Flatten it with an air pad; raise the temperature to PMMA glass transition temperature (Tg) 105 °C under vacuum and keep it constant for 10 minutes, then apply isostatic pressure on the flat plate and keep it for 30 minutes, the size depends on the area of ​​the fish skin; keep the pressure and cool down and Release the mold at 70°C to obtain a replica template with a negative mold of shield scales printed on it. The replica template is turned over by prepolymer vacuum casting method, and polydimethylsiloxane (PDMS) prepolymer is selected as the casting material, and the im...

Embodiment 3

[0055] A food processing factory uses a two-stage screw feeder to transport flour with a certain amount of moisture. The first-stage spiral blade does not use a shark shield scale structure, but is used to control the speed of the screw feeder's flour delivery; the second-stage spiral blade The shark shield scale structure is designed on the top to ensure that the adhesion of flour to the spiral blade is reduced when conveying flour with a certain amount of moisture. After high-precision scanning of the pretreated shark skin structure, the overall structure of multiple shark shield scales was obtained, and multiple groups of multiple shark shield scale overall structures were pressed on the spiral blades by mechanical pressing method, and the overall structure of multiple shark shield scales The part of the structure that protrudes from the helical blade is located on the front of the blade, and the edge of the overall structure of multiple shark shield scales is smoothed so th...

Abstract

The invention discloses a feeder with a bionic shark skin shield scale structure and a manufacturing method thereof. Specifically, the shark trunk epidermis is pretreated to make a shark shield phosphorus structure biological template, and a single shark shield scale structure and a shark shield scale structure are obtained by scanning. The relative position and overall surface topography data of multiple shark shield scales in a large area are directly or indirectly processed and copied on the helical blade according to certain scaling ratios and rules, and the helical blade with the bionic shark skin shield scale structure is installed on the helical blade. The feeder is used to convey materials with high viscosity, agglomeration and poor fluidity, so as to reduce drag and noise, prolong the life of the feeding mechanism and ensure smooth feeding.

Description

technical field [0001] The invention belongs to the application field of engineering bionic technology, in particular to a feeder with a bionic shark skin shield scale structure and a manufacturing method thereof. Background technique [0002] In recent years, in building materials, electric power, chemical industry, metallurgy, coal, aluminum and magnesium, machinery, light industry, grain and food processing and other industries, especially the research and development of new technologies and new processes have produced a large number of new materials with different properties. Some of the materials are dispersed powder at room temperature, but in the process of transportation and packaging, due to the change of moisture and temperature, they are easy to stick and agglomerate, and have poor fluidity, such as biomass powder, coal powder, sludge, dross, chicken manure , Feed, etc., it is difficult to carry out effective transportation by conventional pneumatic feeding equipm...
