Abstract
The utility model provides an explosion-proof electric heating device. An explosion-proof fan is mounted at the rear part of a box body; explosion-proof electric heating tubes are fixed at the front part of the box body and arranged at the air channel of the air outlet of the explosion-proof fan; a closed explosion-proof junction box is arranged on one side of the box body, and a cover plate is fixed on a box body via bolts to form the explosion-proof junction box; both the two wiring terminals of the explosion-proof electric heating device are arranged in the explosion-proof junction; both the fan and the electric heating tubes are explosion-proof; and the wiring terminals of the electric heating tubes are all arranged in the closed explosion-proof junction, so that the electric connection part of the electric heating device is isolated from a hazardous gas environment, even if the current is on or off and sparks are generated at the wiring terminal of the electric heating device, burning or explosion is not generated. The explosion-proof electric heating device is particularly suitable for an occasion where gases are heated under the explosion gas environment during the industrial production.
Description
Technical field
The utility model relates to the commercial power firing equipment, is specially adapted to have the electroheat equipment that the occasion of damp heats.
Background technology
In the industrial processes, need under explosive gas atmosphere, heat gas by the use electric heating equipment sometimes.Because the electric heating tube that existing electroheat equipment adopts (forms heater with the resistance wire energising; Resistance wire is contained in the pipe, and the filling insulating heat-conduction material processes in the pipe) two terminations being connected with power line expose in air, and the break-make owing to circuit during use can form electric spark; Like this; Under the situation that has damp to exist, will burn, even the danger of blast.
The utility model content
The purpose of the utility model provides a kind of explosion-proof type electric heating equipment, so that the terminals of electric heating tube and explosive gas atmosphere are isolated each other.
This novel purpose is achieved in that a kind of explosion-proof type electric heating equipment; Comprise explosion-proof electric heating tube; Explosion-proof fan is installed in the casing rear portion, and said explosion-proof electric heating tube is fixed on the casing front portion, and explosion-proof electric heating tube is arranged on the gas passage of air outlet of explosion-proof fan;
Casing one side is provided with the closed anti-explosion terminal box; Anti-explosion terminal box is formed through being bolted on the box body by cover plate; Two terminals of explosion-proof electric heating tube all are arranged in the anti-explosion terminal box.
Above-mentioned casing is surrounded by the upper and lower, left and right side plate and forms.
Above-mentioned anti-explosion terminal box is provided with power cable and introduces the hole.
Above-mentioned anti-explosion terminal box is provided with temperature control system.
On the above-mentioned explosion-proof electric heating tube radiating fin is installed.
The beneficial effect of the utility model is:
1, blower fan, electric heating tube all adopt explosion-proof type; The terminals of electric heating tube promptly all are arranged in the anti-explosion terminal box (airtight) two outer ends simultaneously; Thereby the electric connecting member of electric heater and hazardous gas environment are kept apart; Even spark appears in the terminal stud of electric heater during current switching, can not cause yet the burning or fire.
2, the surface temperature of temperature control system with working temperature and electrothermal tube in the real-time monitoring terminal box is set in terminal box, during temperature exceeding standard, directly outage.Further improved the fail safe of operation.
