Abstract
The utility model relates to a blade foot end pouring device for a wind mill, which comprises a foot end structural laying layer, a guide net arranged at the front end of the foot end structural laying layer and a resin draft tube arranged at the upper part at the upper front end of the guide net, and further comprises an air pervious isolating film and a vacuum pumping mechanism. The air pervious isolating film is covered on the guide net and between the outlet of the resin draft tube and the front side adjacent to the foot end structural laying layer; and the foot end structural laying layer, the guide diversion, the resin draft tube and the air pervious isolating film are arranged in the vacuum pumping mechanism. The utility model has the advantages that because the auxiliary air extracting model of the air pervious film is added on a guide layer, residual air bubbles clamped in resin are eliminated, so that the compactness of the products is improved, the resin is poured more completely, and the product quality is improved. Moreover, because a structural plane is exhausted, the pouring speed and the quality stability can be effectively improved.
Description
Technical field
The utility model relates to a kind of device for casting, relates in particular to a kind of blade root end pouring device for wind mill.
Background technology
The fan blade butt is the thick pure glass fibre reinforced plastic structure layer of 90mm～100mm.
The technology of available technology adopting makes that the whole filling process time is long, and technical difficulty is big, and control parameter complexity, reason are to be that remaining bubble is arranged in the resin, is easy to be mixed in the structure sheaf and causes defective.
Summary of the invention
The utility model technical issues that need to address have provided a kind of blade root end pouring device for wind mill, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: root end structure shop layer; Layer front end is provided with the water conservancy diversion net in described root end structure shop, settles a resin mozzle in the online upper front end of water conservancy diversion; Also comprise: a ventilative barrier film; Described ventilative barrier film cover water conservancy diversion online and at the delivery outlet of resin mozzle between the front side near root end structure shop layer; A vacuum drawing mechanism; Described root end structure shop layer, water conservancy diversion net, resin mozzle and ventilative barrier film are in the vacuum drawing mechanism.
Compared with prior art, the beneficial effects of the utility model are: owing to increase the auxiliary mode of bleeding of ventilative barrier film on the water conservancy diversion layer, get rid of the remaining bubble that is entrained in the resin, thereby improve the packing of product, make the more thorough of resin perfusion, improve the quality of products; Because the total face is being bled, can effectively improve rate of flooding and quality stability again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: root end structure shop layer 1; Layer 1 front end is provided with water conservancy diversion net 2 in described root end structure shop, and upper front end is settled a resin mozzle 3 on water conservancy diversion net 2; Also comprise: a ventilative barrier film 4; Described ventilative barrier film 4 cover on the water conservancy diversion net 2 and at the delivery outlet of resin mozzle 3 between the front side near root end structure shop layer 1; A vacuum drawing mechanism 5; Described root end structure shop layer 1, water conservancy diversion net 2, resin mozzle 3 and ventilative barrier film 4 are in vacuum drawing mechanism 5.
The course of work of the present utility model is: after the perfusion beginning, resin begins to flow at first in mozzle, and flow in the middle of the layer of root end structure shop by the water conservancy diversion net, and permeates and fill whole root end structure gradually.By the water conservancy diversion web area before resin no show root end structure, increase the ventilative barrier film of one deck, should have only ventilative body by ventilative barrier film, the special functional attributes of saturating resin not utilizes the characteristic of this barrier film, increase the vacuum suction source in this zone, can effectively absorb the bubble that is mixed in the resin filling process wherein, but not hinder resin flow, make the central resin air bubble content of arrival structure sheaf lower, effectively improve the packing of product, reduce the product porosity.Owing to be to bleed in whole plane, can effectively avoid improving the quality of products and stability owing to the uneven envelope defective that produces of resin flows.
