Description
Technical Field
The utility model relates to an explosion-proof electric heater of marine air conduit belongs to heater facility technical field.
Background
Cold air enters the barrel from the air inlet, is heated to a required temperature by the U-shaped electric heating pipe, then exits from the air outlet, enters the hot air pipeline and is conveyed to a required place. Cabin space is little, and equipment is many, and an independent marine air pipe explosion-proof electric heater need occupy certain space, makes the space between equipment and the equipment diminish, to the operation of equipment: the maintenance is inconvenient. In the wiring cavity of the explosion-proof electric heater for the marine air pipeline, an overtemperature protection thermal resistor is installed, an overtemperature alarm instrument is required to be arranged in a control cabinet, when the surface heating temperature of an electric heating pipe is too high, the overtemperature protection thermal resistor outputs a signal to the overtemperature alarm instrument, and the overtemperature alarm instrument realizes automatic power-off and heating stopping. The overtemperature alarm instrument occupies the space of the control cabinet, increases the space of the control cabinet in the cabin, reduces the gap between equipment, and increases the cost of the overtemperature alarm instrument. A common explosion-proof thermal resistor is arranged at an outlet of the explosion-proof electric heater of the marine air pipeline and is matched with an outlet temperature measuring instrument in the control cabinet to display and adjust the heating temperature, but the precision of the common explosion-proof thermal resistor is insufficient, so that the marine requirements cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: an explosion-proof electric heater for air pipeline for ship is designed, the air inlet is connected to cold air pipeline via flange, and the air outlet is connected to hot air pipeline via flange. A barrel of the marine air pipeline explosion-proof electric heater is changed into a rectangular barrel, a wiring cavity is welded on the rectangular barrel, and a U-shaped electric heating tube extends into the rectangular barrel. An overtemperature protection temperature controller is installed in the wiring cavity, a temperature value is set, when the temperature of the heater exceeds the temperature value, the overtemperature protection controller automatically inputs a signal to the control cabinet, a control circuit of the control cabinet is automatically powered off, and heating is stopped. At the exit of marine air pipe explosion-proof electric heater, install a accurate export temperature measurement explosion-proof thermal resistance, the model is the WR type, can accurate demonstration, adjust the export temperature, satisfies marine demand.
Due to the adoption of the technical scheme, the effect is obvious:
1. the installation space of equipment in the cabin is saved, and the operation and the maintenance of the equipment are convenient.
2. An overtemperature alarm instrument is omitted from the control cabinet, so that the space occupied by the control cabinet is reduced, the space of the control cabinet in the cabin is reduced, the operation and maintenance of equipment are facilitated, and the cost is also reduced.
3. An outlet is provided with an anti-explosion thermal resistor with the model WR, so that the marine requirement is met.
