Abstract
The utility model discloses an isolator for a gas electric heating furnace, which is produced by burning insulated fire-resistant materials and positioned on a frame inside the furnace by a fixed axle. The utility model takes the shape of a circle-type lug boss and the lug boss is composed of two coaxial circular rings (1, 2) with different diameters, wherein, grooves (3) are distributed on the outer circumference of the small circular ring (2) and the height of the small circular ring (2) is bigger than the diameter of a heater strip used in the gas electric heating furnace. The isolator has the advantages of high heat efficiency and rapid gas heating.
Description
Technical field
The utility model relates to the insulator that a kind of gas electric furnace is used.
Background technology
At present used insulator is the hollow tubing conductor that equidistant groove is arranged on the outer wall that is fired into by refractory material in the gas electric furnace, heating wire is just around between the groove of hollow tubing conductor, the heat radiation surface that sizable heat transfer area sends in the heating wire is to insulator, can not form convection current between insulator and the gas, the heat transferred that insulator receives is relatively more difficult to main flow of gas, it is poor to improve heat transfer temperature just must to improve the heating wire self-temperature, so the useful life of heating wire is short.
Summary of the invention
The utility model is exactly at the problems referred to above, and insulator used in a kind of gas heating stove is provided, and it can make gas heating fast, and heat efficiency height.
The utility model is achieved in that a kind of gas electric furnace insulator, it is to be fired to form by fixed axis by refractory material to be installed on the framework in the stove, it is circular boss, and boss is made up of the coaxial annulus that two diameters do not wait, and is distributed with groove on the neighboring of small circle ring.
The height of small circle ring is greater than the diameter of the used heating wire of gas electric furnace.
Heating wire all has the space between the groove on the small circle ring, heating wire and the large circle plane on small circle ring in electric furnace, helps the convection current of gas, helps the heat radiation of heating wire, has accelerated the programming rate of gas.Simultaneously the contact area between heating wire and the insulator has all been reduced in the gap between them, simultaneously between heating wire and the insulator for line contacts, this all helps reducing thermal loss, the heat efficiency of raising gas electric furnace.The radial dimension and the large circle of insulator have certain altitude, have both guaranteed the structural strength of itself, have also guaranteed thickness of insulating layer, guarantee Electrical Safety.

Embodiment
According to Fig. 1, shown in Figure 2, used insulator in the gas electric furnace, it is to be fired to form by fixed axis by insulating refractories to be installed on the framework in the stove.Insulator is circular boss, and boss is made up of two different coaxial annulus 1,2 of diameter, is evenly distributed with groove 3 on the neighboring of small circle ring 2.The height of small circle ring 2 is greater than the diameter of the heating wire of using in the electric furnace.
Claims (2)
1, a kind of gas electric furnace insulator, it is to be fired to form by fixed axis by insulating refractories to be installed on the framework in the stove, it is characterized in that it is circular boss, boss is made up of coaxial annulus (1), (2) that two diameters do not wait, is distributed with groove (3) on the neighboring of small circle ring (2).
2, insulator according to claim 1 is characterized in that the diameter of the height of small circle ring (2) greater than the used heating wire of gas electric furnace.
