Abstract
The utility model relates to a metal tubular electric heater, which aims to solve the technical conditions that a current metal heater has great temperature differences of each point on the surface, and is not meets the explosion-proof detecting standards, thereby not becoming an explosion-proof product. The utility model provides an explosion-proof reinforcing type metal heater which is provided with tubes which are sleeved in internal and external interval, wherein the internal tube is filled with insulating heat conducting power material and a helix electric-heat wire thereof, and the two ends of the internal tube are provided with a plug and the external terminal of the electric-heat wire. The technical scheme not only has heating property with excellent evenness, also can meet the standard requirements of an explosion-proof product, but also can be used as an explosion-proof product in working places required with the explosion-proof requirements.
Description
Technical field
The utility model relates to the tubular metal electric heater.
Background technology
The tubular metal electric heater is widely used in heating such as water, oil, acid, alkali, nitre grooves, and in device such as fusible metal melting furnace, electric airheater, drying box, hot-die, motor and flame-proof type explosion-proof electric heater and the electric product, its agent structure is that the crystal magnesium oxide powder and the spiral heating wire wherein that are filled with good insulation performance and heat conductivility in metal tube constitute jointly.That this series products has is simple in structure, the heat efficiency is high, mechanical strength good, characteristics such as easy for installation, but during this series products detects, usually to detect selected point surface temperature temperature difference big because of each, can't reach explosion-proof examination criteria, thereby hindered this series products and enter vast explosion-proof technology market.
The utility model content
Goal of the invention of the present utility model is to dwindle the tube-surface each point temperature difference, make it to meet the anti-explosion product standard-required and a kind of explosion-proof reinforced metal heater is provided.The explosion-proof reinforced metal heater that the utility model provides, the major technique content of its technical scheme is: a kind of explosion-proof reinforced metal heater, be provided with two-layer internal and external partition encasement tube, filling is provided with insulating heat-conductive farinose material and spiral heating wire wherein in its internal layer body, and two ends are provided with shutoff and heating wire external terminal.
The disclosed explosion-proof reinforced metal heater technical scheme of the utility model, it between inner and outer pipes the insulated heat-conducting medium layer, intersperse among uniformly on the outer tube tube wall through wall, inner layer pipe heat, thereby effectively guaranteed the uniformity of outer tube tube wall each point temperature, it not only has the better heating properties of uniformity, also reach the anti-explosion product standard-required, can be used as the explosion-proof performance product and be applied to have in the workplace of requirement of explosion proof.
Description of drawings
Accompanying drawing is the sectional structure chart of explosion-proof reinforced metal heater of the present utility model.
Embodiment
Accompanying drawing has provided an example structure of the explosion-proof reinforced metal heater of the utility model.This explosion-proof reinforced metal heater includes two-layer internal and external partition encasement tube 1,2, be filled with the magnesia powder 3 of insulating heat-conductive and the spiral heating wire 4 that is provided with along the body center line in its internal layer body 1, two ends are provided with the external screw rod 7 of ceramic jacket shutoff 6 and heating wire electrical connection.Outer tube 2 and inner layer pipe 1 interval suit, its wall 5 can be to be the heat conduction wall of heat-conduction medium with the air, also can be the heat conduction wall of filling insulating heat-conduction material.
