Description
Technical field
The utility model relates to heater, specifically a kind of device that wherein steel band is heated of being particularly useful in making steel band reinforced polyethylene spiral ripple pipe technology.
Background technology
Steel band reinforced polyethylene spiral ripple pipe is to be matrix with high density polyethylene (HDPE) (PE), is shaped to waveform as the main support structure with the steel band of surface applied adhering resin, and twines with polythene material and to be combined into whole double-walled helical corrugation pipe.When making steel band reinforced polyethylene spiral ripple pipe at present, at first need steel band is unreeled, after the preheating oven preheating, adopt frequency heating device to be heated to 190 degrees centigrade, enter mould through the samming baking oven again, make adhering resin be coated in steel strip surface equably thus, cool off rolling then.Existing steel band heating system exists bulky, baking oven energy consumption height, intermediate frequency induction heating device failure rate height, heating-up temperature is difficult to regulation and control, and the binder resin coating on the steel band is irregular, easy to crack, adhesive effect is poor, many shortcomings such as percent defective height.
The utility model content
The purpose of this utility model be exactly to provide that a kind of floor space is little, the adhering resin coating is effective, energy consumption is low, convenient and practical, be particularly useful for heater that steel band in the steel band reinforced polyethylene spiral ripple pipe is heated.
The purpose of this utility model is achieved in that
Steel band reinforced polyethylene spiral ripple pipe heater provided by the utility model, include coil, infrared temperature temperature measurer, temperature controller, its key points in design is that said coil is provided with on the polytetrafluoroethylene skeleton of axial rectangular opening in being wrapped in, and coil surface is provided with the thermal insulating layer; The end of polytetrafluoroethylene skeleton is provided with the infrared temperature temperature measurer, and the output of this temperature measurer is connected with temperature controller, and temperature controller is by silicon controlled rectifier and add thermal control plate and be connected with coil.
The utility model after steel band unreeled, passes the rectangular opening in the polytetrafluoroethylene skeleton in use, power-on, this moment, steel band and coil produced electromagnetic induction, and induction coil is given the steel band that will heat electrical energy transfer, and electric energy is a heat energy at the steel band inner transformation again then; When steel band is heated to design temperature, under keeping warm mode, entering mould, make to make adhering resin be coated in steel strip surface equably thus, cool off rolling then.
The setting that the utility model is controlled automatically and added thermal control plate by electromagnetic induction, temperature, make that whole device can be according to actual needs segmentation, subregion, the heating by easy stages of steel band heating, both can realize steel band preheating, intensification, heat insulation integrated thus, can effectively prevent steel band irregular, the bonding disadvantage such as insecure of the temperature inequality, the binder resin coating that cause that sharply heats up again.
Adopt the utility model that steel band is heated, can make the peel strength of steel band binder resin meet fully quality standard (〉=70N/cm), also can omit preheating oven of the prior art and samming baking oven, conservation of power 53% simultaneously.
The utility model is simple in structure, and coil is arranged on the whole periphery of polytetrafluoroethylene skeleton, therefore is convenient to very much adopt wind-cooling heat dissipating, thereby has solved the high problem of cooling system failure rate in the heating in medium frequency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model includes coil 2, infrared temperature temperature measurer 6, temperature controller 5, silicon controlled rectifier 4.Coil 2 high-frequency line coiling, infrared temperature temperature measurer 6, temperature controller 5, silicon controlled rectifier 4 and add thermal control plate 3 and can select commercially available commodity for use.Coil 2 is wrapped on the polytetrafluoroethylene skeleton 8, is provided with axial rectangular opening in this skeleton 8, and this hole is used for interspersed steel band 1.Can press close to steel strip surface to greatest extent after rectangle annular distance design of the present utility model can make coil 2 winding shapings, thereby help strengthening the electromagnetism heats.After coil 2 is wrapped on the polytetrafluoroethylene skeleton 8, add one deck thermal insulating layer 7 again on its surface, to increase the heat insulation effect of device self.The end of polytetrafluoroethylene skeleton 8 (being the end that shifts out of steel band 1) is provided with infrared temperature temperature measurer 6.The test probe of this temperature measurer 6 is aimed at the position that steel band 1 shifts out, and the output of infrared thermometer 6 is connected with temperature controller 5.Temperature controller 5 is by silicon controlled rectifier 4 and add thermal control plate 3 and be connected with coil 2.After steel band is heated, infrared thermometer 6 detects its temperature, temperature value is delivered to temperature controller 5, its output signal indication silicon controlled rectifier 4 is adjusted trigger angle, add thermal control plate 3 by regulation and control thus and come regulating winding 2 magnitude of current sizes, the realistic demand of thermal energy that finally makes heater and produced (coating adhering resin technological requirement steel band need be heated to 190 ℃).
Preferably be connected with 3 on the temperature controller 5 of the present utility model and add thermal control plate (as the 3a among the figure, 3b, 3c), it is connected with the coil 2 that is wrapped in polytetrafluoroethylene skeleton 8 front portions, middle part and rear portion respectively.Can control the magnitude of current of the coil 2 of different parts by the thermal control plate (3a, 3b, 3c) that adds that splits thus, so that the more realistic demand of whole device.The front portion that for example is wound with the polytetrafluoroethylene skeleton 8 of coil 2 is set to the preheating zone, the middle part is set to the thermal treatment zone, the rear portion is set to heat preservation zone, then according to the temperature requirements of zones of different, set adding thermal control plate accordingly, thereby guaranteed that the utility model device can finish preheating, heating, the insulation operation of steel band in the lump.The utility model in use, steel band 1 can influence the induction reactance value of coil as the iron core of coil 2, therefore should add steel band and detect as the necessary condition that starts induction heating on circuit.
