Embodiment Construction

[0018] The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

[0019] Such as figure 1 As shown, a vacuum infusion device for forming wind power blades includes a mold 1, a resin barrel 3, a curing agent barrel 4, a quantitative output circuit of the curing agent, and a preform 2 made of dry fiber reinforced material laid in it; the resin barrel 3 is sequentially connected to the resin quantitative circulation output circuit and the mixer 5; the curing agent barrel 4 is sequentially connected to the curing agent quantitative output circuit and the mixer 5; the mixer 5 is connected to multiple injection seats for preform 2 injection 6. Resin quantitative circulation output circuit and curing agent quantitative output circuit keep the mixing ratio of resin and curing agent stable.

[0020] In a preferred embodiment of the pres...

Abstract

The invention discloses a vacuum pouring device for wind power blade molding, and mainly solves the problems that in an existing technology, an existing pouring process existing process is low in controllability, complex in process, overpowered in experientiality, easy to mix with bubbles, and bad in site environment. The vacuum pouring device for wind power blade molding includes a mould, a resinbarrel, a curing agent barrel, a curing agent quantitative output loop, and a performing body made of dry fiber reinforced materials and laid in the curing agent quantitative output loop. The resin barrel communicates a resin quantitative cycle output loop and a mixing device in sequence. The curing agent barrel communicates the curing agent quantitative output loop and the mixing device in sequence. The mixing device communicates multiple colloid injecting seats used for injecting colloid for the performing body. Through the scheme, the vacuum pouring device for wind power blade molding reaches the goal of being good in controllability and not easy to mix with bubbles, and has a high practical value and a high promotion value.

Description

technical field [0001] The invention relates to the field of forming wind power blades, in particular to a vacuum pouring device for forming wind power blades. Background technique [0002] Wind turbine blades are the most basic and core components of wind power generation systems. They can be formed by hand lay-up, prepreg, vacuum bag pressing, vacuum injection molding, etc. The so-called vacuum injection process refers to laying dry fiber reinforced material preforms in the mold, then impregnating the resin into the preforms under vacuum negative pressure, and demoulding after curing. [0003] The traditional vacuum infusion process has the following limitations: the process is poorly controllable, the infusion time and infusion effect cannot be controlled; the process is complicated and the experience is too strong; air bubbles are easily mixed in the infusion process to cause defects such as whitening of the root of the blade; the amount of resin used is uncontrollable ...
