Abstract
The utility model relates to an anti-explosion electric heater which can heat air in inflammable gas. The anti-explosion electric hater comprises an electric heating pipe. An electric heating wire is arranged in the electric heating pipe, explosion isolating boxes are arranged at the two ends of the electric heating pipe, and the two ends of the electric heating pipe are sealed and stretched into the explosion isolating boxes. Anti-explosion joints are arranged on the explosion isolating boxes, cables are arranged in the anti-explosion joints, and the electric heating wire in the electric heating pipe is connected with the cables. The anti-explosion electric heater is characterized in that: each explosion isolating box presents the shape of a cylinder, and is composed of a cylinder body and a cylinder cover; and a through hole is arranged in the circumferential direction of a cylinder bottom of the cylinder body. The electric heating pipe is arranged along the circumferential direction of the two cylinder bodies, and the two ends of the two cylinder bodies are respectively sealed with the help of nuts and are respectively fixed in the corresponding pair of through holes on the two cylinder bottoms. The anti-explosion electric heater can be used for heating gas in the environment with or without inflammable gas. Therefore, the application range of the anti-explosion electric heater is not limited.
Description
Technical field
The utility model relates to a kind of electric heater.Specifically, be the anti-explosion electric heater that can in imflammable gas, heat to air.
Background technology
As everyone knows, conventional electric heater all is a tabular, and promptly its electric heating tube is and is arranged side by side in one plane.Because electric heating tube is and is arranged side by side in one plane, makes the quantity of electrothermal tube be restricted.And the quantity one of electrothermal tube is few, requires the power of single heating tube to want high.Power one height of single heating tube, its surperficial temperature are just high, reach as high as more than 300 ℃.Therefore, this electric heater can only be used in the environment of no imflammable gas gas is heated, and can not be used for having the environment of imflammable gas that gas is heated, and the scope of application is restricted.
The utility model content
The problem that the utility model will be dealt with problems provides a kind of anti-explosion electric heater.This anti-explosion electric heater can be used in the environment of no imflammable gas gas is heated, and can be used for having the environment of imflammable gas that gas is heated again, and the scope of application is unrestricted.
For addressing the above problem, take following technical scheme:
Anti-explosion electric heater of the present utility model contains electrothermal tube.Heating wire is arranged in the electrothermal tube, and there is Flameproof box at its two ends, and the electrothermal tube two ends are the sealing shape and stretch in the Flameproof box.Explosion proof joint is arranged on the Flameproof box, cable is arranged in the Explosion proof joint, this cable links to each other with heating wire in the electrothermal tube.Be characterized in that described Flameproof box is cylindric, it is made up of cylindrical shell and cover, and circumferentially there is through hole at the tube end of cylindrical shell.Described electrothermal tube is along the circumferential arrangement of two cylindrical shells, at the bottom of their two ends are the sealing shape and are fixed on two by nut respectively in the corresponding a pair of through hole.
Further improvement of the utility model is, temperature probe is arranged between electrothermal tube, and temperature detect switch (TDS) is arranged in the cylindrical shell, and temperature detect switch (TDS) links to each other with temperature probe by metal hose.
Of the present utility model further the improvement be, temperature probe one end has external screw thread, and the tube of cylindrical shell has screw at the end, and temperature probe one end is by in the screw at the bottom of screwing into tin.
Take such scheme, have the following advantages:
Because Flameproof box is cylindric, it is made up of cylindrical shell and cover, and circumferentially there is through hole at the tube end of cylindrical shell.Described electrothermal tube is along the circumferential arrangement of two cylindrical shells, at the bottom of their two ends are the sealing shape and are fixed on two by nut respectively in the corresponding a pair of through hole.Be the traditional electric heater that is arranged side by side with electrothermal tube and compare, can increase the quantity of electrothermal tube greatly.The quantity more than one of electrothermal tube, the power of single electrothermal tube is just little.The power one of electrothermal tube is little, and its surperficial temperature is with regard to low (being lower than 120 ℃).And the surface temperature of electrothermal tube is low, just can be used in the environment of imflammable gas gas is heated.Therefore, anti-explosion electric heater of the present utility model can be used in the environment of no imflammable gas gas is heated, and can be used for having the environment of imflammable gas that gas is heated again, and the scope of application is unrestricted.
Description of drawings
Fig. 1 is an anti-explosion electric heater structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, anti-explosion electric heater of the present utility model comprises 12 electrothermal tubes 6 and two Flameproof boxes.All be tied with heating wire in 12 electrothermal tubes 6.Described Flameproof box is cylindric, and it is made up of cylindrical shell 5 and cover 4 and 4 of cylindrical shell 5 and covers are the sealing shape by screw 3 and are fixed together.All be processed with 12 through holes on the tube end circumferencial direction of two cylindrical shells 5,12 electrothermal tubes 6 are along the circumferential arrangement of two cylindrical shells 5, their two ends are tube that the sealing shape stretches into two bodies 5 respectively in the corresponding a pair of through hole at the end, and by nut 9 are fixed together an end of their two ends and corresponding cylindrical shell 5.
Be fixed with Explosion proof joint 2 on the lateral wall of cylindrical shell 5, be installed with cable 1 in the Explosion proof joint 2, the heating wire in this cable and 12 electrothermal tubes 6 links to each other.
For ease of the temperature on electrothermal tube 6 surfaces is controlled, between electrothermal tube 6, be provided with temperature probe 7, temperature detect switch (TDS) 8 is installed in the cylindrical shell 5, temperature detect switch (TDS) 8 links to each other with temperature probe 7 by metal hose.Wherein, temperature probe 7 one ends are processed with external screw thread, and the tube of cylindrical shell 5 is processed with screw at the end, and temperature probe 7 has an externally threaded end to screw in the screw of tube at the end.
