Abstract
The utility model mainly relates to a far infrared heating device for drying and baking finish. It is composed of leading-out electrode 1, insulator 2, electric heating wire 3, refractory material 4 and metal shell 7, and is characterized by that the electric heating wire is placed in the refractory material, the metal shell can completely seal the refractory material layer, its periphery is equipped with sealing edge, and its external surface is equipped with far infrared radiation layer. Compared with the prior art, the utility model has the advantages of strong far infrared radiation, high thermal efficiency, energy saving, difficult oxidation of the heating wire, long service life, good cold and hot shock resistance, etc.
Description
The utility model belongs to electrical heated appliance, relates generally to the electric calorifie installation that is used for dry baking vanish.
Far infrared heating technology has energy savings, enhances productivity, and guarantees characteristics such as product quality, is widely used at home and abroad.At present, the far-infrared heater of prior art generally has materials such as carborundum, zircon sand, pottery, quartz to make, therefore, ubiquity bad mechanical strength, and cold-resistant thermal shock resistance properties is poor, and the heat efficiency is lower, a little less than the far infrared radiation, the easy oxidation of heating wire, shortcoming such as useful life is short.
It is strong that the purpose of this utility model provides a kind of far infrared radiation, and heat efficiency height, heating wire are difficult for oxidation, long service life, mechanical strength height, metallic seal formula far infrared electric heating plate that cold-resistant thermal shock resistance properties is good.
The utility model is by metal shell, be positioned at the heating wire of refractory masses, the insulator of extraction electrode that connects with heating wire and support extraction electrode is formed, it is characterized in that metal shell seals the refractory masses that is embedded with heating wire fully, and fix with sealing strip, on the surface of metal shell the far infrared radiation layer is arranged.
Between metal shell one side and refractory masses, adiabator layer can be set; At the fixed head 8 that is connected with on the surface of metal shell more than 2 or 2.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an A-A cutaway view of the present utility model
1 extraction electrode, 2 insulators, 3 heating wire, 4 refractory materials, 5 far infrared radiation layers, 6 adiabator layer, 7 metal shells, 8 fixed heads, 9 sealing strips among the figure.
Extraction electrode 1 connects with heating wire, support and fixing extraction electrode by insulator 2, heating wire 3 is positioned among the refractory material 4, metal shell 7 all seals refractory material 4, around metal shell 7, there is sealing strip 9 fixing, on the surface of metal shell 7, can adopt plasma spraying, thermal spraying, manually brush, ooze assorted or oxidation technology is processed into far infrared radiation face 5.In metal shell 7 one sides, between refractory material 4 and metal shell 7 inner surfaces one deck insulation material 6 can be set, make single face metallic seal formula far infrared electric heating plate.Insulation material 6 can be made with materials processings such as rock wool, alumina silicate fibre, asbestos.
The utility model compared with prior art, it is strong to have far infrared radiation, thermal efficiency height, energy savings, mechanical strength height, cold-hot impact property are good, heating wire is difficult for the characteristics such as oxidation, long service life. Can be used for the industrial products baking vanish such as automobile, tractor, bicycle, sewing machine; Also can be used for the oven dry of cast steel core, chemical coating of welding electrode, printing-ink, chemical industry medicine, ceramic; The dipping that also can be used for motor, transformer solidifies.
The utility model and prior art Performance Ratio be:
Technical parameter the utility model prior art (GB4654-84)
Normal direction total emissivity＞0.9＞0.83
Cold-resistant thermal shock resistance properties (20 ℃ of-650 ℃ of repetition tests)＞500 times＞3 times
Cold and hot insulation resistance＞100M Ω＞2M Ω
Mechanical strength is tens times of prior art
Shock resistance＞100 hour＞2 hours
Useful life＞10000 hour＞2000 hours
Cost: reduce by 15% than prior art.
