Abstract

The utility model relates to a constant temperature field fluid electric heater, which consists of a connection box, a process flange, an electric heating tube, a container, support plates and an over-temperature sensor, wherein the electric heating tube adopts a 'U'-shaped steel tube; a guide rod is arranged in the electric heating tube; a connection end is arranged at one end of the guide rod, and the other end of the guide rod is connected with an electric heating wire; and magnesium oxide powder is filled between the electric heating wire and the inner wall of the electric heating tube. Intervals of the electric heating wire are increased according to the flow direction of a medium, and the power surface density of the electric heating tube is decreased according to the flow direction of the medium, so that local overheat spots are difficultly produced on the surface of the electric heating tube in a working process to prevent reduction in the insulativity of the magnesium oxide powder, the phenomena of burnout, electric leakage, breakdown and the like of the electric heating wire are effectively prevented, and the service life of the electric heater is prolonged. The electric heater has the advantages of resistance to high temperature and high voltage, high corrosion resistance, convenience for replacement, applicability to explosion-proof places, high popularization value and the like.

Description

The electric heater for fluid of a kind of equitemperature field
Technical field:
The utility model relates to a kind of electric heater, the electric heater for fluid of particularly a kind of equitemperature field.
Background technology:
Run into phenomenons such as electric heater generation high temperature overtemperature alarm, high-temperature insulation decline, high-temperature electric heat element electric leakage puncture through regular meeting in the industrial process field of electric heating, influenced the normal use of electric heater greatly, hindered process safety and production.Heater element in the conventional procedures electric heater is an electrothermal tube; Electrothermal tube is made according to the equally distributed principle of heating wire; Heating for the immersion inactive liquid should be most suitable; Yet for the mobile particularly medium heating of gas of medium of process; Just have the heater outlet place because high-temperature gas causes the too high magnesia insulating properties that makes of the interior heating wire temperature of electrothermal tube to descend, the very little heating wire temperature that further makes of heating wire spacing rises, and causes phenomenons such as heating wire blows, electric leakage, puncture at last.
The utility model content:
The purpose of the utility model is to provide a kind of high temperature resistant, good insulating, long service life, is applicable to the electric heater for fluid of the equitemperature field of explosion-proof occasion.
To achieve these goals, the utility model proposes following technical scheme realization:
The electric heater for fluid of a kind of equitemperature field is made up of terminal box, process flange, electrothermal tube, container, gripper shoe, over-temperature sensor; Electrothermal tube links to each other with terminal box, and terminal box is provided with cable access, fills the nitrogen mouth; Gripper shoe is installed between electrothermal tube fixes, on the electrothermal tube outer wall, be provided with over-temperature sensor, electrothermal tube and the welding of process flange, and insert in the container; It is characterized in that: electrothermal tube adopts " U " shape steel tube; Be provided with in the electrothermal tube and draw rod, draw an excellent end and be provided with terminals, the other end is connected with heating wire; The spacing of heating wire is put to bare cloth by close according to the flow direction of medium, fills magnesia powder between heating wire and electrothermal tube inwall.
The soluble technical problem of the utility model is:
Heating wire is put to bare cloth by close according to the flow direction of medium in the electrothermal tube; Make the power meter surface density of electrothermal tube according to MEDIA FLOW to from big to small; Make the surface temperature of electrothermal tube be not easy to produce local hot spot in the course of the work like this, cause the magnesia powder insulating properties to reduce, effectively prevent phenomenons such as heating wire blows, electric leakage, puncture; Prolong the service life of electric heater, be applicable to explosion-proof occasion.
Description of drawings:
Fig. 1 is the utility model patent structure figure;
Fig. 2 is the utility model patent electrothermal tube cutaway view.
The specific embodiment:
As shown in the figure, the electric heater for fluid of a kind of equitemperature field is made up of terminal box 1, process flange 2, electrothermal tube 3, container 4, gripper shoe 5, over-temperature sensor 6; Electrothermal tube 3 links to each other with terminal box 1, and terminal box 1 is provided with cable access 7, fills nitrogen mouth 8, fills nitrogen mouth 8 nitrogen filled protections; It is fixing that 3 of electrothermal tubes are installed gripper shoe 5, on electrothermal tube 3 outer walls, is provided with over-temperature sensor 6, electrothermal tube 3 and 2 welding of process flange, and insert in the container 4; Electrothermal tube 3 adopts " U " shape steel tube, is provided with in the electrothermal tube 3 and draws rod 9, draws rod 9 one ends and is provided with terminals 10; The other end is connected with heating wire 11; Fill magnesia powder 12 between heating wire 11 and electrothermal tube 3 inwalls, the spacing of heating wire 11 is put to bare cloth by close according to the flow direction of medium, make the power meter surface density of electrothermal tube 3 according to MEDIA FLOW to from big to small; Make the surface temperature of electrothermal tube 3 be not easy to produce local hot spot in the course of the work like this; Cause magnesia powder 12 insulating properties to reduce, effectively prevent phenomenons such as heating wire 11 blows, electric leakage, puncture, prolonged the service life of electric heater.
That this patent has is high temperature resistant, good insulating, long service life, be applicable to advantages such as explosion-proof occasion, has great promotional value.
