Abstract
The invention relates to a blade mould for an energy-saving aerogenerator, which is characterized in that an interlayer of the blade mould is provided with a heating layer; and the heating layer comprises heating wires and a heat-conducting layer filled around the heating wires. In the invention, the heating wires which are originally arranged outside the mould are arranged inside the mould, so that the heating wires are closer to the working surface, and the heat transfer efficiency is improved; the heat conducting layer is arranged around the heating wires so as to improve the heat conducting efficiency of the heating wires to the working surface of the mould and guarantee the even heating for preventing heat stress deformation caused by nonuniform heating; in order to prevent the increase of energy consumption caused by thermal diffusion to outside, a thermal preservation layer is arranged between the heating wires and the bottom surface of the mould to furthest prevent energy from losing, and an optimal energy-saving effect is obtained.
Description
Technical field
The present invention relates to a kind of blade of wind-driven generator mould.
Background technology
The material of blade of wind-driven generator mould is divided into metal and nonmetal two big classes, have pluses and minuses separately, wherein, fiber reinforced plastic mold comparatively more in the nonmetal mould sees, advantages such as that fiberglass has is in light weight, specific strength is high, corrosion-resistant, electric insulation, anti-TRANSIENT HIGH TEMPERATURE, its big shortcoming that is used on the mould is that heat conductivility is poor, is the 1/100---1/1000 of metal material.For the mould of fiberglass material generator blade, if adopt the electrical heating means that it is heated, needed 7 to 8 hours just can make die-face reach desired operating temperature (80 ℃), heat time heating time is long and energy consumption is big; Since the factor of heat conductivility difference, can only carry out the integral body heating of mould, and can not segmentation heat, limited the innovation of fan blade processing technology.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the existing shortcoming that blade of wind-driven generator mold hot transmission efficiency is low, heat time heating time is long, energy consumption is big, and a kind of blade mould for energy-saving aerogenerator is provided.
The technical solution adopted for the present invention to solve the technical problems is as follows: blade mould for energy-saving aerogenerator, it is characterized in that having zone of heating in the interlayer of mould, and this zone of heating includes the warmware silk, be filled in the heat-conducting layer around the described warmware silk.
In order better to solve the problem that the application proposes, further technical scheme of the present invention is as follows:
Be provided with heat resistant layer between zone of heating described in the present invention and the mould bottom surface.
Beneficial effect of the present invention is as follows: the present invention places mould inside with original outer warmware silk of mould that places, and makes warmware flight lead working face nearer, has improved heat transfer efficiency; And around the warmware silk, be provided with heat-conducting layer, improved the efficient of warmware silk, and guaranteed even heating, prevent mould because the thermal stress deformation that the inequality of being heated causes to die-face heat conduction; In order to prevent that heat from spreading to the external world, thereby increase energy consumption, be provided with heat resistant layer between warmware silk in this mould and the mould bottom surface, guarantee that farthest energy does not lose, reached best energy-saving effect.Take after these a series of means, when mould is heated, only needed 2-3 hour can make die-face reach 80 ℃, shortened heat time heating time greatly, improved operating efficiency.

The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the present invention is described in further detail.But the invention is not restricted to given example.
As shown in Figure 1, blade mould for energy-saving aerogenerator (in this example be that example describe with the bed die), its improvements are to have zone of heating 2 in the interlayer of mould, and this zone of heating 2 includes warmware silk 21, be filled in the heat-conducting layer 22 around the described warmware silk 21.1 is die-face among the figure, and 11,12 is fiberglass.For make in the mould thermal stress evenly, balance, in the present embodiment, zone of heating 2 is arranged in the middle part interlayer of mould.
As shown in Figure 1, be provided with heat resistant layer 3 between zone of heating 2 of the present invention and the mould bottom surface, this heat resistant layer can be selected the cork wood layer for use, such as the Balsa cork wood.Heat resistant layer 3 can prevent heat to the mould diffuse outside, and the heat that warmware silk 21 sends can utilize the energy to greatest extent fully to the die-face transmission, has further shortened the mold heated time, has improved operating efficiency.
In the present embodiment, as shown in Figure 1, the both sides up and down of zone of heating 2 have high temperature resistant glass fibre reinforced plastic layer 31,32, zone of heating 2 is clipped between this two-layer high temperature resistant glass fibre reinforced plastic layer 31,32, what directly contact with zone of heating is the high temperature resistant glass fibre reinforced plastic layer, therefore can not change its proterties, improve the resistance to elevated temperatures of mould because of Gao Re.
Heat-conducting layer of the present invention can be selected the mixed with resin heat transfer medium that contains heat conductor for use, and heat conductor can be one or more the mixing in granular metal heat conductor, the nonmetal heat conductor of graininess, granulated metal heat conductor, the nonmetal heat conductor of powdery.But heat conductor aluminium, copper, aluminium oxide etc.
As shown in Figure 2, warmware silk 21 vertically is distributed in the zone of heating (not drawing among the figure) by snakelike.As shown in Figure 3, warmware silk 21 vertically is distributed in the zone of heating (not drawing among the figure) by snakelike segmentation (a, b, c, d).
As shown in Figure 1, the mould outside is enclosed with one deck thermal insulation layer 5, these thermal insulation layer 5 outer protective layers 6 that also are enclosed with.In this example, thermal insulation layer is used rock wool, and protective layer is an aluminium foil.
The master data of the relevant energy-conservation aspect of this blade mould for energy-saving aerogenerator is as follows:
1, owing to adopted heat-conducting layer, the former mould general power that needs to be equipped with is kept to 90 kilowatts by 110 kilowatts;
2, owing to adopted energy-saving shop layer structure, reached mould process temperature by original 7-8 hour heat time heating time, is reduced to reach the mould process temperature in 2-3 hour, energy-conservation up to more than 70%, saves manufacturing time 30%;
3, single-piece, every blade energy consumption original mould of split run production need 1760 kilowatt hours, adopt present technique to need 990 kilowatt hours, energy efficient 56.2%;
4, press 0.85 yuan of commercial power/degree and calculate, single-piece, split run are produced every blade and are saved 654.5 yuan of costs.
