Integrated perfusion assembly line for wind turbine blade and perfusion process thereof

Abstract

The invention discloses an integrated perfusion assembly line for a wind turbine blade and a perfusion process thereof. The integrated perfusion assembly line comprises a resin mixing room, a resin mixing and defoaming all-in-one box and a perfusion storage room, wherein an ultrasonic room is formed in the resin mixing and defoaming all-in-one box; the outer wall of the resin mixing and defoamingall-in-one box has a heating or cooling function and is equipped with a bleeder pipe with a gas vent valve and a suction pipe with a suction port valve; the suction pipe can be externally connected with a vacuum pump; a resin component A feed pipe and a resin component B feed pipe are mounted on the resin mixing room; the resin mixing room communicates with the ultrasonic room through a resin drainage pipe; the ultrasonic room is connected to at least one perfusion storage room through a resin feeding pipe and a resin conveying pipeline which are mutually connected; a feeding pipe valve is mounted on the resin feeding pipe; a conveying pipeline valve is mounted on the resin conveying pipeline; a discharge pipe is mounted on the perfusion storage room; a discharge control valve is mounted on the discharge pipe; and the discharge pipe is connected to a product vacuum system. The integrated perfusion assembly line performs mixing and defoaming simultaneously, and adopts an integrated perfusion technology to guarantee favorable perfusion quality.

Description

technical field [0001] The invention relates to the technical field of vacuum infusion of blades of wind power generating sets, in particular to an integrated infusion line for wind power generation blades and an infusion process thereof. Background technique [0002] With the continuous increase of the single unit capacity of large wind turbines, in order to improve the utilization rate of wind energy, the length of blades used in wind turbines is also getting longer and longer, but with the continuous increase of blade length, it also brings new challenges to the infusion molding of blades . On the one hand, the increase of the blade length puts forward higher requirements on the infusion process; on the other hand, the longer the blade, the more difficult it is to infuse the blade, especially the perfusion of large blades requires more material per unit time, and it is difficult to transport materials, and the resin degassing cannot keep up. , risk of infusion due to exo...

AI Technical Summary

Problems solved by technology

[0010] 1. The blade perfusion needs to purchase a professional resin mixing machine. The general import cost of this equipment is 1 million units, which is expensive

[0011] 2. 20 personnel are required for perfusion (including feeding, transporting, guarding, and inspection personnel), and there are many personnel

[0012] 3. The amount of resin infused into large leaves is large, and the infusion time is long. In summer, the temperature is high and the resin heats up too quickly, and there is no effective cooling method. In winter, the temperature is low, the resin viscosity is high, and the infusion rate is slow, which affects the infusion quality.

[0013] 4. There are many feed pipes filled with large blades, and the air in the feed pipe is difficult to get rid of.
