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: cut off 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 to 6 % phosphate aqueous solution to wash, and peel off the subcutaneous tissue to obtain shark scute tissue; fix the washed shark scute tissue in 25% glutaraldehyde aqueous solution at 5°C for 20-30 hours, and then use the volume fraction Gradient dehydration with gradually increasing ethanol solution; fix the edge of the dehydrated shark scute tissue with tooling to prevent warping during the drying process, and then place the flattened and fixed shark scute tissue in a drying oven at 60°C Under...

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. First prepare the shark shield scale structure template. In a self-made vacuum hot press, use a polymethyl methacrylate (PMMA) plate as a substrate, and lay a 150mm×300mm tiger shark shark skin scale on it with the face down and use the plate to supplement it with air. Flatten the mat; 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 at 70°C The lower mold is removed to obtain a replica template printed with the negative mold of the shield scale. The replica is turned over by prepolymer vacuum casting method, and polydimethylsiloxane (PDMS) prepolymer is selected as the casting material to obtain the i...

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 white shark skin structure, the overall structure of multiple shark shield scales is obtained, and multiple groups of multiple shark shield scale overall structures are pressed on the spiral blades by mechanical pressing method, and multiple shark shields The part of the overall structure of the scales protruding 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 that it can...

Abstract

The invention discloses a feeder with a bionic sharkskin placoid scale structure and a manufacturing method of the feeder. The manufacturing method specifically comprises the steps that a shark placoid scale structure biological template is manufactured after pretreatment is conducted on a shark body skin, the relative positions and overall surface appearance data of a single shark placoid scale structure and a plurality of shark placoid scales in a large area are obtained through scanning, direct or indirect processing duplication is conducted on a spiral blade according to a certain scalingand ruler, the spiral blade with the bionic sharkskin placoid scale structure is mounted in a spiral feeder and used for conveying materials being high in viscidity, prone to caking, and poor in mobility, and thus the effects of reducing resistance and noise, prolonging the life of a feeding mechanism and guaranteeing smooth feeding are achieved.

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...
