Abstract
The invention relates to an explosion-proof electric heater and in particular relates to the explosion-proof electric heater capable of heating air in a combustible gas. The explosion-proof electric heater comprises an electric heating tube, wherein the electric heating tube is internally provided with an electric heating wire; explosion-proof boxes are arranged at the two ends of the electric heating tube; the two ends of the electric heating tube stretch into the explosion-proof boxes in a sealed manner. Each explosion-proof box is provided with an explosion-proof connector and each explosion-proof connector is internally provided with a cable; the cable is connected with the electric heating wire in the electric heating tube. The explosion-proof electric heater is characterized in that each explosion-proof box is cylindrical and is composed of a barrel body and a barrel cover; through holes are formed in the barrel bottom of each barrel body in the peripheral direction. The electric heating tube is arranged along the peripheral direction of the two barrel bodies, and the two ends of the electric heating tube are fixed in one pair of corresponding through holes in the two barrel bottoms in the sealed manner by virtue of nuts respectively. The explosion-proof electric heater provided by the invention can be used for heating gas in an environment without the combustible gas and also can be used for heating gas in an environment with the combustible gas, and an applicable range is not limited.
Description
Technical field
The present invention relates to a kind of electric heater. Specifically, be in imflammable gas, to carry out airThe anti-explosion electric heater of heating.
Background technology
As everyone knows, conventional electric heater is all tabular, and its electric heating tube is and is arranged side by side in oneIn individual plane. Be arranged side by side in one plane because electric heating tube is, the quantity of electrothermal tube is subject toTo restriction. And the quantity one of electrothermal tube is few, require the power of single heating tube to want high. Single heating tubePower one height, its surperficial temperature is just high, reaches as high as more than 300 DEG C. Therefore, this electricity addsHot device can only be used in the environment without imflammable gas gas is heated, and can not be used for having combustibilityIn the environment of gas, gas is heated, the scope of application is restricted.
Summary of the invention
The problem that the present invention will deal with problems is to provide a kind of anti-explosion electric heater. This anti-explosion electric heatingDevice, can be used in the environment without imflammable gas gas is heated, and can be used for having again combustibilityIn the environment of gas, gas is heated, the scope of application is unrestricted.
For addressing the above problem, take following technical scheme:
Anti-explosion electric heater of the present invention contains electrothermal tube. In electrothermal tube, have heating wire, its two ends have everyQuick-fried case, electrothermal tube two ends are sealing shape and stretch in Flameproof box. On Flameproof box, there is Explosion proof joint, explosion-proof connecingIn head, have cable, this cable is connected with the heating wire in electrothermal tube. Be characterized in that described Flameproof box is for circleTubular, it is made up of cylindrical shell and cover, and, circumferentially there is through hole at the cylinder end of cylindrical shell. Described electrothermal tube is along twoThe circumferential arrangement of body, corresponding at the bottom of their two ends are sealing shape and are fixed on two by nut respectivelyIn a pair of through hole.
Further improvement of the present invention is, has temperature probe between electrothermal tube, has temperature detect switch (TDS) in cylindrical shell,Temperature detect switch (TDS) is connected with temperature probe by metal hose.
Of the present invention further improvement is that there is external screw thread temperature probe one end,, has at the cylinder end of cylindrical shellScrew, temperature probe one end is by 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 cylinder end of cylindrical shell.Described electrothermal tube is along the circumferential arrangement of two cylindrical shells, and their two ends are sealing shape by nut respectively and fixOn at the bottom of two in corresponding a pair of through hole. Compared with being with electrothermal tube the traditional electric heater being arranged side by side,Can greatly increase the quantity of electrothermal tube. 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 (lower than 120 DEG C). And the surface temperature of electrothermal tubeSpend lowly, just can be used in the environment of imflammable gas gas is heated. Therefore, of the present inventionAnti-explosion electric heater, can be used in the environment without imflammable gas gas is heated, and can use againIn the environment that has imflammable gas, gas is heated, the scope of application is unrestricted.
Brief description of the drawings
Fig. 1 is anti-explosion electric heater structural representation of the present invention;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, anti-explosion electric heater of the present invention comprises 12 electrothermal tubes 6 and twoIndividual Flameproof box. 12 interior heating wire that are all tied with of electrothermal tube 6. Described Flameproof box is cylindric, its byCylindrical shell 5 and cover 4 form and cylindrical shell 5 and cover 4 between by screw 3 be sealing shape be fixed together.On the cylinder end circumferencial direction of two cylindrical shells 5, be all processed with 12 through holes, 12 electrothermal tubes 6 are along twoThe circumferential arrangement of body 5, their two ends are respectively sealing shape, and to stretch into the cylinder of two bodies 5 corresponding a pair of on the endIn through hole, and by nut 9, be fixed together the cylinder end of their two ends and corresponding cylindrical shell 5.
On the lateral wall of cylindrical shell 5, be fixed with Explosion proof joint 2, in Explosion proof joint 2, be installed with cable 1, shouldCable is connected with the heating wire in 12 electrothermal tubes 6.
Be convenient to the temperature on electrothermal tube 6 surfaces to control, between electrothermal tube 6, be provided with temperature control and visit7, temperature detect switch (TDS) 8 is installed in cylindrical shell 5, temperature detect switch (TDS) 8 is by metal hose and temperature probe 7Be connected. Wherein, temperature probe 7 one end are processed with external screw thread,, are processed with screw at the cylinder end of cylindrical shell 5,Temperature probe 7 has externally threaded one end to screw in the screw at the cylinder end.
To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can be in the situation that not departing from the spirit or scope of the present invention,Realize in other embodiments.
