Abstract
The utility model relates to an improved explosion-proof electric heater belonging to electric heating facilities technologic field. A vessel body of the electric heater is provided with an inlet and an outlet, the external portion of the electric heater is coated with heat insulating material and one end of the electric heater is provided with an explosion-proof chamber. The explosion-proof chamber is fixedly welded with the vessel body by a group of sleeve pipes, and the explosion-proof electric heating device is penetrated inside the explosion-proof chamber by the sleeve pipes from the vessel body, a conducting wire which is got through the end socket of the electric heater device from the explosion-proof chamber. The improvement of the utility model is that a heat insulating shell is fixed outside the flange of an end of the vessel body which is adjacent to the explosion-proof chamber, the shell is filled with heat insulating material, and at least a piece of division board is fixed between the sleeve pipes. When heated, the heat insulating material which is provided inside the shell not only can separate heat, but also can prevent the heat from dissipating, and the division board not only can enhance the sleeve pipes, but also can form a air-convection space, thereby ensuring good air-cooling effect. In addition, compared with the prior art, the utility model is simplified in structure, convenient in technology, and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of anti-explosion electric heater, and especially a kind of improvement of anti-explosion electric heater heat insulation structure belongs to electrical heating facility technology field.
Background technology
The function of existing anti-explosion electric heater is the fluid media (medium) heating with hydrogen, oil and so on, its typical structure as shown in Figure 1, columned container body 5 is shaped on import 7 and outlet 4, the outside insulation material 11 that coats, one end is equipped with explosion-proof chamber 13, by the 8 fixing welding of one group of sleeve pipe, electric heating device 6 is penetrated in the container body 5 by explosion-proof chamber 13 by sleeve pipe 8 between this explosion-proof chamber 13 and the container body 5, and lead penetrates the termination that connects electric heating device 6 by explosion-proof chamber 13.During work, the electric heating device energising is with the fluid heating that enters in the container body, again by outlet output.
Be delivered to explosion-proof chamber for fear of heat, burn to avoid insulated cable, an end of the contiguous explosion-proof chamber of container body is welded with waterway 2, can form the cooling water circulation by cooling water import and export 9,10, thereby play heat-blocking action.In addition, in order to dispel the heat the sleeve pipe 8 outer fins 12 that also are welded with.
Heat energy loss was bigger during this type of existing anti-explosion electric heater used, its reason one is that water cooling is taken away many heats, the 2nd, pass many electric heating devices in the every sleeve pipe, the inner gap greatly that exists, therefore the medium fluid that enters wherein will form convection circulation, not only effect of heat insulation is bad, and influences heat insulation.
The utility model content
The purpose of this utility model is: the problem at above prior art exists by architecture advances, proposes a kind of energy-saving explosion-proof electric heater (referring to Fig. 2) that can reduce thermal losses.
In order to reach above purpose, energy-saving explosion-proof electric heater of the present utility model comprises container body (5), and described container system has import (7) and outlet (4), the outside insulation material (11) that coats, and an end is equipped with explosion-proof chamber (13); Weld by one group of sleeve pipe (8) is fixing between described explosion-proof chamber (13) and the container body (5), electric heating device (6) by sleeve pipe (8) by penetrating in the container body (5) in the explosion-proof chamber (13), lead is penetrated by explosion-proof chamber (13), connect the termination of electric heating device (6), its improvements are, the outer fixedly lagging casing of one end flanges (3) of the contiguous explosion-proof chamber of described container body is loaded insulation material (2) in this shell, fixing a slice division board (1) at least between the described sleeve pipe.
During heating, the insulation material in the shell not only can play the effect of trap heat, and can prevent that heat scatters and disappears, and division board had then both played the effect of reinforcing sleeve, formed the cross-ventilation space again, had guaranteed good air cooling effect.In addition, compared with prior art, the utility model structure designs simplification, technology is convenient, can reduce manufacturing cost.
It is to pass an electric heating device in the every sleeve pipe that the utility model further improves, clearance control each other is at 0.5 ± 0.1 millimeter, can effectively avoid fluid media (medium) to form convection current betwixt like this, scatter and disappear, strengthen effect of heat insulation thereby further reduce heat.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
The structural representation of the existing anti-explosion electric heater of Fig. 1.
Fig. 2 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The energy-saving explosion-proof electric heater of present embodiment as shown in Figure 2, an end of container body 5 is shaped on import 7, the top be shaped on the outlet 4, outside coating alumina silicate heat-preservation cotton 11.Explosion-proof chamber 13 is positioned at the other end of container body 5, and by the 8 fixing welding of one group of sleeve pipe, two division boards 1 spaced apart are fixed in welding between each sleeve pipe, both can play booster action to sleeve pipe, form air-cooled convection current runner again between the two.Electric heating device 6 is by sleeve pipe 8, penetrate in the explosion-proof chamber 13 by (by flange 3, heat-preservation cotton 2 and division board 1) in the container body 5, pass an electric heating device in the every sleeve pipe, gap each other is 0.5 millimeter, can stop fluid media (medium) to form thermal convection current therein, thereby the isolation heat avoids lost.Lead is penetrated by explosion-proof chamber 13, connects the termination of electric heating device 6.The lagging casing that one end flanges, the 3 outer fixedly galvanized iron sheets of the contiguous explosion-proof chamber of container body are made is loaded heat-preservation cotton 2, thereby is replaced waterway in this shell, not only heat insulation but also prevent that heat scatters and disappears.
The energy-saving explosion-proof electric heater that experiment showed, present embodiment can be suppressed at the temperature of explosion-proof chamber under the control temperature, thereby guarantees that the PVS insulated conductor is not damaged by high temperature, significantly reduced simultaneously thermal losses, energy-saving effect is obvious, and it is simple in structure, and manufacturing cost reduces.
In addition to the implementation, the utility model can also have other embodiments.For example, insulation material also can be mullite, glass, asbestos etc. except alumina silicate.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
