Technical field
The utility model belongs to a kind of electromagnetic induction heater, is mainly used in the heater of plastic-wire drawing machine bake plate.
Background technology
The main effect of the bake plate in the plastic-wire drawing machine be exactly to the fillet plastic sheeting heat, stretching and heat treatment, for plastic wire-drawing also be and an important ring.Bake plate length is about 2m, and the about 150mm of both ends of the surface arc length is equipped with electric heater unit in the plate; See it is one arc from profile.At present, what existing plastic-wire drawing machine bake plate added thermal recovery all is resistance wire heat blocks, has that firing rate is slow, power consumption is big, the life-span is short, at the bottom of the temperature control precision, causes the thermal efficiency low at last.
Summary of the invention
The purpose of this utility model provides a kind of heater that is used for the plastic-wire drawing machine bake plate, has that firing rate is fast, the thermal efficiency is high, is heated evenly, the temperature control precision height.
The purpose of this utility model can adopt following technical scheme to realize: it comprises eddy-current heating control power supply, one group of induction coil calandria and insulation layer, the insulation layer is arranged on the bottom of bake plate, the induction coil calandria is provided with insulation layer bottom, each induction coil calandria is made of shell body and one group of electromagnetic induction coil, electromagnetic induction coil is arranged in the shell body, it is shaped as dish, and electromagnetic induction coil is connected with eddy-current heating control power supply by a load connecting line.
Shell body is a cast aluminum casings, is provided with Ferrite Material within it, and at the inside and outside electro-magnetic screen layer that is provided with one deck anti-electromagnetic radiation of cast aluminium shell.Be arranged between each electromagnetic induction coil in the shell body and be connected in series.
From the above mentioned, the utility model is to utilize electromagnetic induction principle, the voltage of 220/380V is flowed to dish-shaped induction heating circle after the frequency conversion of induction type control power inverter, thereby make electronics and atom high velocity impact in bake plate or the metal heating produce the thermal oscillation energy, make its direct heating, and utilize the insulation layer that is wrapped on the bake plate to the metal heating insulation, prevent heat-energy losses.Thereby can utilize the magnetic energy and the effective temperature of controlling bake plate in the dish-shaped heating collar of electric field fully, just can reach needed preheat temperature, improve firing rate less than 10 minutes.The utility model can will be made the arc of arbitrary shape after electromagnetic induction coil and the curing of cast aluminium sheathing material, and makes the circular arc dish induction heating circle that matches with it according to the bake plate of its obstructed size.Have thermal efficiency height, quick heating, life-span length and simple operation and other advantages.Structural manufacturing process is reasonable in design, easy for installation, the tangible characteristics of power savings.
