Description
Technical field
The utility model relates to a kind of wind-powered blade mold far infrared heating system structure, particularly about a kind of heating system device and structure that is used for the megawatt wind-power blade mould.
Background technology
In recent years, wind-power electricity generation is the green energy industry of state key development, wherein, trend towards maximizing under the power that is arranged on the consideration generating of wind-powered electricity generation unit and the usefulness, to capture more wind energy, produce more electric power, meet the economic benefit of wind field utilization, so the maximization megawatt wind-power blade has produced with regard to corresponding.
Wind electricity blade is shaped by large-scale blade mold making, by the glass cloth of laying plural layer on blade mold, with priming by vacuum resin is immersed back curing and makes; Prerequisite, the curing of resin has decisive influence for the making of blade, and assists resin solidification, and the heating system that then need be dependent on mould is with the temperature parameter of mold heated to the appointment of blade resin solidification; Common wind-powered blade mold heating means have two kinds of water-cycle heating and electric heating systems, are summarized as follows now:
1, water-cycle heating (mould inner fluid medium heating systems), see also Figure 1 and Figure 2: water route (or steam, deep fat etc.) loop heating system has been a kind of comparative maturity and widely used technology in the mould, the main equipment that sees through heating (or cooling) fluid media (medium), make the heating pipe line 20 of hot water (or heat medium), carry out hot fluid and circulate mould enforcement heating by being embedded in the fan blade mould inside in advance; Fig. 1 is the back side partial schematic diagram of die flip, can find out that heating pipe line 20 is between fan blade die surface layer 10 and following coating 30, and superficial layer 10 is the epoxy resin material with following coating 30, heating pipe line 20 is enclosed in the mould, following coating 30 outer side covers are with heat-preservation cotton, the blade mold structure.
Water-cycle heating applies to the fan blade mold heated, its rate of heat addition stable and controllable, the mould temperature difference is controlled, can there be the phenomenon that the subregion is overheated or do not heat, heating pipe line is longer 20 service lifes, this circulating system also has a benefit simultaneously, and oppositely (cooling) is used in parts cooling or the control exotherm that solidifies the back exactly.
The hydronic inconvenience of water (fluid media (medium)) be in: need tissue and construction circulation heating pipe line 20 and add the equipment of hot fluid medium, as shown in Figure 2, the heating pipe line 20 of circulation is set in mould, this pipeline includes water lines 23 and outlet pipeline 26, the built-in circulation heating pipe line 20 of whole group, not only increase outside the die cost, tubes rows is established and will be prolonged the cycle that mould is produced; In addition, because water circulation system need use die heater that water is externally heated in advance, and then enter fan blade mould inside heating pipe line 20 by flexible pipe, and with electrical heating water is implemented heating at die heater, there is heat energy loss in heating process, after mould is implemented to have heated, the hot water of circulatory system internal duct will emit, and causes the partial heat energy loss again, makes that the whole system energy consumption is bigger, the not high defective of heat energy efficiency is arranged, increased use cost; As water-cycle heating in heating pipe line 20 if pipe blocking or leakage, because of heating pipe line 20 is to imbed mould inside, keep in repair very difficultly, will influence die life.On the other hand, consider fluid media (medium) and pre-buried heating pipe line 20, the general copper pipes that adopt of heating pipe line 20 add the heat conductive medium (being generally the mixture of aluminium powder or copper powder and resin) that the shop is covered around the copper pipe, add mold support structure, entire die weight increases relatively, requirement to the mould support strength also improves, and causes mould steelframe supported weight also can improve, so the weight of entire die increases, compared to comparable size (1.5MW mould) electrical heating mould, weight increases by 4 tons at least.
Another obstruction is to be absorbed by mould gradually and produce temperature difference when heat, and the fluid temperature (F.T.) that causes flowing out in outlet pipeline 26 exits is starkly lower than entry pipeline 23 porch temperature, makes mold heated inhomogeneous.Though this problem can see through flowing of accelerating fluid and reduce heat output and improve, this factor often is not operated the person and ignores and form the uneven phenomenon in mold heated zone.Utilize water to be used as heat medium and also have another shortcoming: the heating-up temperature scope is subjected to (boiling point of heat medium itself) restriction, and when requiring to surpass 100 ℃ as if the resin solidification system temperature, then this system can't reach temperature requirements.
2, electric heating system (heating of mould in-built electrical heated filament): electricity (heated filament) heating system mainly sees through the heating wire 29 that is embedded in mould inside, see also shown in Figure 3, under the situation of energising, with heating wire 29 is that thermal source carries out mold heated, and combine with Numeric Control Technology, by means of computer simulation system, control a kind of mold heated system of Temperature Distribution.
Electric heating system compared to the benefit of water heating system is: the heating controllability is good, (water adds two about 144KW of die heater power of thermal recovery in the energy consumption reduction, electric heating system heating general power is about 110KW), advantage such as mold weight is lighter, and comprehensive die manufacturing cost is lower.By means of computer simulation system, can accurately control Temperature Distribution, in the solidification process of leaf production, can utilize occasionally hot video picture camera of thermoelectricity and data logger to write down Temperature Distribution simultaneously.See through the controller have microprocessor, the Temperature Distribution that can obtain estimating according to zone and time, control assembly more can be programmed to step, gradient, control and chilling temperature distribution in advance, reaches the more dynamical purpose of mold heated system.
But electric heating system exists an obvious defects to be exactly: heating wire 29 is embedded in mould inside, because heating wire 29 and temperature control circuitry are easier to damage, causes this heating system maintenance cost height.The for example damage of heating wire 29, need to use thermal imaging system to search trip point, with aforementioned water heating system in the same manner, lay heating wire 29 at fan blade die surface layer 10 back side, with the mould structure of fiberglass as following coating involution, when heating wire 29 damaged, expense height, the time of maintenance die apparatus were long equally, to destroy mould structure simultaneously and change components and parts, influence die life.The components and parts of electrical heating simultaneously make the blade product surface shape occur burning if take place may cause local heat too high unusually; If do not heat, then may cause products solidifying incomplete, influence product quality and structural strength.
As mentioned above, two kinds of located by prior art all exist some careless mistakes, and demand the improver urgently; In view of all disappearance of above-mentioned located by prior art, the creator concentrates on studies by feat of the working experience in wind electricity blade field for many years, draws the utility model creation wind-powered blade mold far infrared heating system structure finally.
