Abstract
The present utility model relates to an explosion-proof electric heater which belongs to the electric heating equipment technology field. The electric heater comprises a container body provided with an inlet and an outlet, an explosion-proof cavity is arranged on one end of the container body, the explosion-proof cavity is fixedly connected with the container body through a set of sleeves, the sleeves are metal sleeves, two ends of the sleeves are respectively welded and fixed with the container body and the explosion-proof cavity, a high temperature resistant insulation layer is lined inside each metal sleeve, and the electric heater passes into the explosion-proof cavity from the container body through the metal sleeves provided with the high temperature resistant insulation layers. As the sleeves are made of metal materials, the strength is ideal, the sleeves can endure high pressure and temperature, good insulation is guaranteed by the high temperature resistant insulating layers, and using demands of a large-power and large-current electric heater can be satisfied.
Description
Technical field
The utility model relates to a kind of electric heater, and especially a kind of anti-explosion electric heater belongs to the electric heating equipment technical field.
Background technology
The basic structure of existing electric heater is referring to Fig. 1: cylindrical container body 5 outer wrap insulation materials 11, one ends with import 4 and outlet 7 are provided with explosion-proof chamber 13.Be connected through one group of sleeve pipe 8 between this explosion-proof chamber and the container body 5 and be connected.Electric heating device 6 is penetrated in the explosion-proof chamber 13 by container body 5 through sleeve pipe 8.During work, after the electric heating device energising, with the fluid heating that gets in the container body, again by outlet output.Because the sleeve pipe of prior art adopts ceramic material, so intensity is low, is difficult to bear high pressure, high temperature, power limited can't satisfy the user demand of electric heating device through big electric current.
The utility model content
The purpose of the utility model is: the limitation to above-mentioned prior art exists through architecture advances, proposes a kind of anti-explosion electric heater that can significantly improve heating power.
In order to reach above purpose; The anti-explosion electric heater of the utility model comprises the container body with import and outlet; One end of said container body is provided with explosion-proof chamber; Being connected through one group of sleeve pipe between said explosion-proof chamber and the container body is connected, and its improvements are: said sleeve pipe is a metal sleeve, and two ends are fixing with container body and the welding of explosion-proof chamber respectively; Be lined with temperature-resistant insulation layer in the said metal sleeve, it is indoor that electric heating device penetrates explosion-proof chamber through the metal sleeve that is lined with temperature-resistant insulation layer by container body.
Be understood that; Because sleeve pipe adopts metal material, therefore have desirable intensity, can tolerate very high pressure and temperature; Temperature-resistant insulation layer has wherein guaranteed good insulation performance, therefore can satisfy user demand high-power, large-current electric heater 2000-5000KW.
The utility model further improves and comprises: said metal sleeve has the horn mouth of settling band tapering conducting metal rod towards an end of container body.Said metal sleeve liner has shape to match to be with bell-mouthed temperature-resistant insulation layer.Said temperature-resistant insulation layer is the mica Composite.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structure for amplifying sketch map of an embodiment sleeve portion of the utility model.
Embodiment
Embodiment one
The anti-explosion electric heater basic structure of present embodiment is referring to Fig. 1, and columniform container body 5 has import 4 and is provided with explosion-proof chamber 13 with outlet 7, one ends, outer surface parcel heat-insulation layer 11.As shown in Figure 2, be connected through 8 welding of one group of metal sleeve between explosion-proof chamber 13 and the container body 5---the two ends of metal sleeve 8 are fixing with the tube sheet 5-1 and 13 welding of explosion-proof chamber of container body 5 respectively.Metal sleeve 8 is the little horn mouth of imperial palace outside an end of container body 5 has, and is used to settle the conducting metal rod 14 with tapering, and the pipe liner has shape to match to be with bell-mouthed temperature-resistant insulation layer 12, and this temperature-resistant insulation layer is the mica Composite.The termination welding of resistive band and conducting metal rod constitutes electric heating device 6; The metal sleeve 8 of this device through being lined with temperature-resistant insulation layer 12; Penetrate in the explosion-proof chamber 13 by container body 5,, form terminals by insulation spacer 15 and clamp nut tension tapering secure fixation.
After experiment showed, the structure that adopts present embodiment, even under the high pressure of 500 ℃ high temperature, 5Mpa, electric heater is operate as normal for a long time also, and electrical heating power props up tens KW by original list and brings up to 2000-5000kW, and is progressive very remarkable.
Except that the foregoing description, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
