Abstract
The utility model relates to an energy -conserving explosion -proof electric heater belongs to electric heater unit technical field. This electric heater includes that the output has the cylindrical container body (6) of direct air outlet, support in the container body a set of tubulose electric heater (13, have another name called the resistance tube) rather than the length direction parallel, the input of the container body is equipped with and gas feed (5) through and through wiring chamber (1), the lateral wall in wiring chamber is equipped with binding post (16) be connected with tubulose electric heater electricity. Adopt the utility model discloses an after the structure, even tubulose electric heater power is very big, has also formed through the direct current channel of chamber, electric heater body that works a telephone switchboard because of air intlet and between exporting, and had the entering radiating effect that generates heat of ideal, can not the thermal -arrest to can guarantee sufficient life under the condition that satisfies high -power demand conscientiously.
Description
Technical field
The utility model relates to a kind of electric heater, and especially a kind of energy-saving explosion-proof electric heater, belongs to electric heater unit technical field.
Background technology
As shown in Figure 1, its main composition part comprises explosion-proof wiring chamber 1 ', radiating area 2 ', abutted flange 3 ', gas feed 4 ', container body 5 ', deflection plate 6 ', electric heating tube 7 ', temperature element 8 ', bearing 9 ', gas vent 10 ' to the typical structure of existing anti-explosion electric heater.Its electric heating tube adopted as shown in Figure 2, arranges a resistance wire (coiling type) at the center of pipe, then fills out insulation magnesium powder, then makes after the packing that the draw reaches certain.
Practice shows, above-mentioned existing electric heater exists following shortcoming: the heat 1) distributed due to electrothermal tube internal resistance wire will conduct heat to metal tube envelope by magnesium powder, and therefore heating is slow; 2) there is thermal-arrest phenomenon in the resistance wire in electrothermal tube, when the temperature of metal tube reaches 600 DEG C, resistance wire is up to nearly 1000 DEG C in the middle of magnesium powder, and therefore electric heating element is perishable, and useful life is short; 3) power is difficult to do greatly, and need many electric heating elements, the container after assembling is bigger than normal, and increases production cost.
Summary of the invention
The purpose of this utility model is: propose a kind of heating block, avoid the energy-saving explosion-proof electric heater of thermal-arrest, thus be conducive to energy-conservation, meet powerful user demand.
In order to reach above object, the basic technical scheme of the utility model energy-saving explosion-proof electric heater is: comprise the cylindrical container body that output has straight air outlet, one group of pipe heater parallel with its length direction is supported in described container body, the input of described container body is equipped with the wire connection cavity straight-through with gas feed, and the sidewall of described wire connection cavity is equipped with the binding post be electrically connected with pipe heater.
After adopting structure of the present utility model, even if pipe heater power is very large, also because defining the direct current channel through wire connection cavity, electric heater body between air intlet and outlet, and there is desirable heating enter radiating effect, can not thermal-arrest, thus when conscientiously meeting significant power demand, enough useful life can be ensured.
Further, described pipe heater adopts Nie Network alloy to draw and forms, and diameter is Φ 5mm ~ Φ 150mm, thickness is 0.5mm ~ 15mm.
Further, described wire connection cavity is the tubular that barrel dliameter and described container body match, and described wire connection cavity is fixedly connected with container body flange with the wire connection cavity flange of described container body by adjacent face.
Further again, be spaced from each other by insulator between adjacent tubular electric heater.

Embodiment
Embodiment one
The energy-saving explosion-proof electric heater of the present embodiment as shown in Figure 3 and Figure 4, cylindrical container body 6 is supported on bearing 10, its output has the straight air outlet 9 of band temperature measuring device 11, one group of pipe heater 13(parallel with its length direction is supported see Fig. 4 in this container body 6, also known as resistance tube), adopt resistant to elevated temperatures Nie Network alloy to draw to form, diameter can take the circumstances into consideration to select in 0.5mm ~ 15mm scope at Φ 5mm ~ Φ 150mm, thickness.Be spaced from each other by insulator 14 between adjacent tubular electric heater 13.
The input of tubular container body 6 is equipped with the tubular wire connection cavity 1 straight-through with gas feed 5, and barrel dliameter and the cylindrical container body of wire connection cavity 1 match, and are fixedly connected with container body flange 4 by the wire connection cavity flange 3 of adjacent face.The binding post 16 be electrically connected with pipe heater 13 is equipped with in the two side of wire connection cavity 1.
Because the present embodiment adopts many resistance tube serial or parallel connections to be combined into electric heater, straight-through air-flow in the pipe of each resistance, therefore resistance tube directly adds hot-air, faster than traditional electrical heat pipe 3 times of programming rate, even if its power is very large, also can ensure the temperature of electric heater and ambient air temperature close.Such as when the rear temperature 850 DEG C of electrothermal tube heating, the temperature of outlet air can reach about 800 DEG C, and its mounting structure is compact, significantly reduces manufacturing cost.
Be summed up, the present embodiment tool has the following advantages: 1) pipe heater power is large, can reach tens kilowatts/often prop up; 2) soon heating up, the heat efficiency is high; 3), compact conformation, save manufacturing cost (reducing the diameter of pressure vessel); 4, long service life.
In addition to the implementation, 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.
