Description
Technical field
The utility model is a kind of marine explosion-proof self-control safety type electric heater for pipeline, belongs to electric heater facility technology neck
Domain.
Background technique
It needs to heat air with electric heater for pipeline on ship, be transported in the equipment for needing hot-air.Original technology side
Case is: with general fan blast, by the heat air of U-shaped light pipe electrothermal tube.The starting of electrothermal tube and blower stops by special
Electrical control cabinet carries out automatically controlling, and starts electrothermal tube automatically simultaneously with blower, is automatically stopped.With common blower drum
Wind, blower contact when working with explosion hazard gases in ambient enviroment, are easy to happen explosion accident.The outer surface of U-shaped light pipe electrothermal tube
Heat-transfer area is small, and heat-transfer effect is poor.Dedicated electrical control cabinet volume is larger, heavier-weight, in addition to arrange place placement, peace
Dress, occupies the space on ship, increases the loading capacity on ship.
Utility model content
The utility model technical issues that need to address are: one marine explosion-proof self-control safety type pipeline electric heating of design
Device is equipped with temperature controller, contactor one, contactor two, transformer explosion-proof wiring is intracavitary, and the supply voltage on ship is
440V, the operating voltage of electrothermal tube are 440V, control the starting of electrothermal tube heating work by contactor one, stop.It selects explosion-proof
Supply voltage 440V is become 380V by transformer by the blower of type, blower voltage 380V, controls blower by contactor two
The starting of rotary work stops.Contactor one, contactor two actuation, separation be by respective Inside coil energization, stop Lai
It realizes.When the coil of contactor one is powered, contactor one is attracted, electrothermal tube starting heating；When the coil of contactor one stops
When electric, contactor one is separated, and electrothermal tube stops heating.When the coil of contactor two is powered, contactor two is attracted, blower starting
Work.When the coil blackout of contactor two, contactor two is separated, and blower stops working.After electrothermal tube starting heating, if blower
Do not start air blast, the air of heating cannot be transported in the equipment for needing to heat, and blower does not start air blast, and electrothermal tube is in dry
Burning state, electrothermal tube will be burnt out quickly.Therefore, electrothermal tube has to start automatically simultaneously, be automatically stopped with blower, this requires
Contactor one, contactor two simultaneously automatic pick, be automatically separated, also require contactor one, contactor two coil simultaneously from
It is dynamic to be powered, have a power failure automatically.Temperature sensor is put in electrothermal tube cabinet, measures the intracorporal heating temperature of case at any time.It needs to heat
Temperature can be set by the rotating handle of temperature controller, such as setting value be 100 DEG C, when the intracorporal heating temperature of case
When lower than 100 DEG C, then electrothermal tube starts heating work automatically, and the switch of temperature controller is normally closed, and the coil of contactor one is powered,
Contactor one is attracted.When reaching 100 DEG C, electrothermal tube is automatically stopped heating work, and the switch of temperature controller is become by normally closed
Normally opened, the coil blackout of contactor one, contactor one separates.When the intracorporal heating temperature of case is lower than 100 DEG C, electrothermal tube is automatic
Start heating work, blower automatic starting air blast, the coil of contactor two will also be powered simultaneously, and contactor two is attracted.When reaching
At 100 DEG C, electrothermal tube is automatically stopped heating work, and blower will also be automatically stopped air blast simultaneously, and the coil of contactor two has a power failure, connects
Tentaculum two separates.When being attracted contactor one, contactor two is also attracted；When contactor one separates, contactor two is also separated,
The method that we take is: the coil voltage of the coil, contactor two of choosing contactor one is 220V, with power supply 440V's
Temperature controller and the coil of contactor one, the coil of contactor two are cascaded, return power supply 440V by single line
Another single line on.In this way, the coil of contactor one, the coil of contactor two pass through 220V's when temperature controller is normally closed
Electric current is attracted contactor one, contactor two, makes the electrothermal tube heating work of 440V, make the blower rotary work of 380V.Work as temperature
When degree controller is normally opened, the coil of contactor one, the coil of contactor two do not have electric current, separate contactor one, contactor two,
Electrothermal tube is powered off, stops heating, powers off blower, stop rotating.
Blower is chosen using explosion-proof fan, which contacts when working with explosion hazard gases in ambient enviroment, will not occur quick-fried
Fried accident, safety are good.
On the surface of U-shaped light pipe electrothermal tube, spiral fin is welded, increases heat transfer area, heat-transfer effect is good.
Using above technical scheme, effect is obvious:
1, it is connected with temperature controller with contactor one, contactor two, makes electric heater and blower automatically while starting, certainly
It is dynamic to be simultaneously stopped.
2, contactor one, contactor two, volume of transformer are small, light-weight, and it is intracavitary to be mounted on explosion-proof wiring, do not need in addition
Place is arranged to place, installation.
3, it chooses using explosion-proof fan, safety is good.
4, on the surface of U-shaped light pipe electrothermal tube, spiral fin is welded, heat-transfer effect is good.
