Abstract

The utility model discloses a novel heating element. The novel heating element uses a solid core body made of manganese white copper or nickel-chromium materials as a heating core body, and the periphery of the heating core body is circularly distributed with dense mineral insulation layers; the outer surfaces of the insulating layers are coated with a tooth-shaped metal armoured sheath, a tooth groove of which forms a straight line or a helical shape in the longitudinal direction of the novel heating element. With the characteristics of fire prevention, explosion prevention, corrosion resistance, aging resistance, vibration prevention, wear resistance, large and uniform heat radiation area, etc., the utility model can meet the construction requirements under various environments.

Description

A kind of novel heating element

The utility model relates to a kind of heating element, relates in particular to a kind of element that is used for the oil heating.

At present, in petroleum industry, be used for heating or companion's heat of petroleum pipeline and oil storage tank, adopt ribbon heater or electrothermal tube more.What the crust of ribbon heater adopted is organic material, and its heat-resisting, fire-resistant, wear-resisting, corrosion resistant performance is all relatively poor, and is easy to wear out.Now use more electrothermal tube, owing to be subjected to the restriction of technology and shape, the insulating material that it adopted is can't can closely knit, thereby heat conductivility is reduced, and very easily blows heating wire and influences useful life.

The purpose of this utility model provides a kind of heating element of heat-resisting, fire-resistant, corrosion-resistant, antivibration wear resistant, makes it both have good thermal conductivity, has long useful life again.

Concrete structure of the present utility model is such, and it comprises a heating core body, and uniform ring is around being distributed with the mineral insulation layer around the heating core body, and its improvements are that the outer surface of mineral insulation layer is coated with profile of tooth metal armouring crust.

The teeth groove of described profile of tooth metal armouring crust is vertical along heating element, can be straight, also can be spiral.

The utility model is compared with original technology, has fire-resistant explosion-proof, corrosion-resistant, anti-aging, antivibration wear resistant, area of dissipation is big and characteristics such as even, and can be a kind of desirable oil heating element for 20 years useful life.

Be described in further detail as follows below in conjunction with accompanying drawing to embodiment of the present utility model:

Fig. 1 is the sectional view of this heating element.

The described novel heating element of Fig. 1, it has a heating core body 1, it is that the solid core that adopts manganese-copper or nickel chromium triangle material to make constitutes, the mineral insulation layer 2 that uniform ring constitutes around distributing closely knit magnesium oxide or quartz sand around heating core body 1, mineral insulation layer outer surface is coated with the profile of tooth metallic sheath 3 of the sealing of being made by stainless steel or copper-nickel alloy, its teeth groove is vertical along this heating element, can be straight, also spiral, it is that the mineral insulation layer that will be pressed into shell-like is sleeved on the straight bar-shaped heating core body of 8 millimeters of φ 5-φ in single file, the outside is stainless steel or the White Copper Tubes of 50 millimeters of suit φ 35-φ again, draw through several times then and dial, anneal, make the heating element of the different-diameter that meets various designing requirements.

Claims

1. a novel heating element comprises heating core body (1), mineral insulation layer (2), it is characterized in that the outer surface of mineral insulation layer (2) is coated with profile of tooth metal armouring crust (3).

2, novel heating element according to claim 1, the teeth groove that it is characterized in that profile of tooth metal armouring crust (3) along heating element vertically, can be straight, also can be spiral.
