The present invention discloses an embedded strip, equipment and process for epoxy resin-based fiber-reinforced high modulus wind turbine blades. The embedded strip comprises: a composite material body and a composite surface felt, wherein the composite surface felt is arranged on the upper and lower surfaces of the composite material body; the composite material body is a glass fiber-reinforced epoxy resin composite material; the glass fiber comprises untwisted roving glass fiber, bulked yarn glass fiber and glass fiber cloth, wherein the untwisted roving glass fiber and bulked yarn glass fiber are uniformly arranged in multiple layers along the length direction in the composite material body to form a multi-layer structure, and the glass fiber cloth is arranged in at least one layer along the length direction in the multi-layer structure. The embedded strip is a high modulus embedded strip reinforced with epoxy resin-based fibers. The embedded strip manufactured by this method has the advantages of high modulus, certain toughness and anti-aging performance, and can meet the current production requirements of blades for units below 7MW.

The invention belongs to the technical field of traditional Chinese medicine processing and microbial fermentation. The invention relates to a fructus aurantii processing method, in particular to a fructus aurantii processing method based on functional strain fermentation and fermented fructus aurantii. The invention provides a strain composition. The strain composition contains Aspergillus urumi CQM3. Preferably, the composition can be further compounded with rhizopus arrhizus SGGM1 and / or aspergillus niger HQM2. When the strain composition is used for fermenting the fructus aurantii, the quality of a fructus aurantii processed product can be remarkably improved, white hyphae are uniformly and densely distributed on the appearance, the total content of flavonoid components is increased, the content proportion of flavonoid aglycone components with higher bioavailability is increased, and the antioxidant activity is improved. The invention also develops an adaptive fructus aurantii fermentation process aiming at the strain composition, and the whole fermentation process is controllable in process parameter and strong in stability, has good large-scale production adaptability, and has good application prospect and application value.

The present invention provides a slurry stirring device, an electrode slurry, and a preparation method and application thereof, wherein the slurry stirring device comprises a stirring container, wherein a planetary stirring paddle is arranged in the stirring container, wherein a disperser is integrated inside the planetary stirring paddle, and the slurry stirring device further comprises a lifting controller connected to the disperser, and a driver connected to the disperser and the planetary stirring paddle; the lifting controller is used to control the disperser to be lifted and lowered along the axial direction of the planetary stirring paddle, and the driver is used to control the disperser and the planetary stirring paddle to rotate. The slurry stirring device provided by the present invention can effectively reduce the dead angle of the kneading process of the equipment by adopting a disperser that can be freely lifted and lowered integrated in the planetary stirring paddle, compared with the existing double planetary or planetary dispersed equipment, improve the kneading efficiency and the overall dispersion uniformity of the final slurry; compared with the existing three-planetary equipment, the dilution capacity after kneading is significantly improved, and the preparation time of the slurry is shortened.
