Abstract
The utility model discloses an electric heating pipe with multi-protection and comprises quartz glass heating pipe made of insulating backing material, a conductive heating film and a silver electrode, wherein an inner casing is sheathed in the heating pipe; a gap between the heating pipe and the inner casing is filled with an insulating material layer; both ends of the heating pipe are provided with an insulating glue at the end of the seal insulating material layer. An insulating seal rubber pad is also arranged outside the insulating glue and a protective sleeve is arranged outside the heating pipe. The electric heating pipe with multi-protection has the advantages that apart form double insulation, the insulating seal rubber pads on both ends can avoid accidental electricity leakage caused by the aging of the inner casing and a heat exchanging medium interface, and in addition, the protective sleeve is added, preventing an article from accidentally dropping on a heating surface, which can cause a fire accident. Simultaneously, the heat external loss is reduced and the heat efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of glass-based face electric heating heater members of Ohmic resistance heating, particularly a kind of multiple protective electric heating tube.
Background technology
At present, electric heating heater members on the market mainly adopts heating alloy to make electrothermal tube, and heating alloy is the line heat source of high temperature naked light heating, and electric conversion rate is low, and the life-span is short.In recent years, high temperature resistant substrate surface is modified as suitable wide temperature region, the energy-efficient face electrothermal device of the conductive heating layer of stable performance is existing to be produced.Its insulating substrate adopt multiple materials such as pottery, glass, carborundum all can, the surface is sprayed and is oozed modification, its heat efficiency is up to more than 96%, thermal inertia is little, quick heating, the life-span is long, but continuous operation up to ten thousand hours.Recently, adopt the double insulation electric heating tube of this process for modifying surface in addition.This product is a cover inner sleeve in the electric heating tube, and middle fill insulant is as magnesia etc.The deficiency of this technology is: in case the interface section of inner sleeve and heat transferring medium because of aging or other reasons generation heat transferring medium seepage, heat transferring medium still might contact with the heating film of electric heating tube, causes leaking electricity.In addition, fall on the heating film surface to have disaster hidden-trouble if any other objects.
Summary of the invention
The purpose of this utility model is to provide a kind of suitable wide temperature region for the deficiency that solves above-mentioned technology, stable performance is carried and can improve the heat efficiency and multiple protective electric heating tube safe in utilization.
In order to achieve the above object; a kind of multiple protective electric heating tube of the utility model design; it comprises quartz-glass heating tube, conductive exothermal film and the silver electrode of insulating substrate; be with an inner sleeve in heating tube inside; fill insulant layer between heating tube and the inner sleeve; be provided with the insulating cement of sealed insulating material layer end at the heating tube two ends, outside insulating cement, be provided with the insulator seal rubber cushion again, outside electric heating tube, install protective casing additional.Like this, heat transferring medium can flow in inner sleeve, carries out heat exchange.Its modification thickness of the conductive exothermal film on described quartz-glass heating tube surface is the 3-50 micron.
This multiple protective electric heating tube at inner sleeve of heating tube internal sleeve, is enclosed within on the inner sleeve with the interface of heat transferring medium, except double insulation, increased one deck insulator seal rubber cushion again, thereby one deck protective casing has formed the multiple protective electric heating tube like this.
The utility model has the advantages that except double insulation; the accident electric leakage that the insulator seal rubber cushion at two can protect reasons such as inner sleeve and heat transferring medium interface wear out to cause; add protective sleeve in addition; prevent that the article accident from dropping to heating surface and causing fire incident; reduce heat simultaneously to external loss, improve the heat efficiency.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the organigram of multiple protective electric heating tube of the present utility model;
Among the figure: 1, heating tube; 2, inner sleeve; 3, insulation material layer; 4, insulating cement; 5, conductive exothermal film; 6, protective casing; 7, insulator seal rubber cushion; 8, silver electrode; 9, silica gel inserted sheet cover.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, multiple protective electric heating tube of the present utility model, inner sleeve 2 of cover in heating tube 1.Heating tube 1 can be a quartz-glass heating tube; inner sleeve 2 can be metal tube or non-metallic pipe; middle fill insulant layer 3 can be a magnesia; shut with insulating cement 4 at two ends, and insulating cement can be 704 silica gel, and shut with insulator seal rubber cushion 7 at two; insulator seal rubber cushion 7 can be a silicagel pad; add protective casing 6 at heating tube 1, protective casing 6 can be the aluminium protective sleeve, and the interface of heat transferring medium directly is connected on 2 mouthfuls of the inner sleeves.Many one deck insulation material layers 3 between heating tube 1 outer field conductive exothermal film 5 and the heat transferring medium like this; the protection of formation double insulation; greatly reduce the electric leakage risk of heating tube; the accident electric leakage that reasons such as the insulator seal rubber cushion 7 protection heat transferring mediums at two and inner sleeve 2 interfaces are aging cause; add protective sleeve 6 in addition; prevent that the article accident from dropping to heating surface and causing fire thing mistake, reduced heat simultaneously, improved heat utilization efficiency external loss.
Using method of the present utility model is, heat transferring medium is by the multiple protective electric heating tube, energized, and heating tube 1 produces heat, can heat heated medium (as water, wet goods), reaches efficient heat exchange.
