Description
Technical field
The present invention is a kind of marine explosion-proof self-control safety type electric heater for pipeline, belongs to electric heater facility technology field.
Background technology
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 startup of electrothermal tube and wind turbine stops by special
Electrical control cabinet carries out automatically controlling, and so that electrothermal tube is started automatically simultaneously with wind turbine, is automatically stopped.It is roused with common wind turbine
Wind, when blower fan work, contact 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.
Invention content
The technical problem to be solved in the invention is：A marine explosion-proof self-control safety type electric heater for pipeline is designed,
Explosion-proof wiring intracavitary is equipped with temperature controller, contactor one, contactor two, transformer, and the supply voltage on ship is 440V, electricity
The operating voltage of heat pipe is 440V, controls the startup of electrothermal tube heating work by contactor one, stops.Select the wind of explosion-proof type
Supply voltage 440V is become 380V by machine, blower voltage 380V by transformer, and controlling wind turbine by contactor two rotates work
The startup of work stops.Contactor one, the actuation of contactor two, separation be by respective Inside coil energization, stop realizing
's.When the coil of contactor one is powered, contactor one is attracted, and electrothermal tube starts heating；When the coil of contactor one has a power failure,
Contactor one detaches, and electrothermal tube stops heating.When the coil of contactor two is powered, contactor two is attracted, and wind turbine starts work.
When the coil blackout of contactor two, contactor two detaches, and wind turbine is stopped.After electrothermal tube starts heating, if wind turbine does not open
The air of dynamic air blast, heating cannot be transported in the equipment for needing to heat, and wind turbine does not start air blast, and electrothermal tube is in dry combustion method shape
State, electrothermal tube will be burnt out quickly.Therefore, electrothermal tube has to automatically start simultaneously, be automatically stopped with wind turbine, and this requires contacts
Device one, contactor two simultaneously automatic pick, be automatically separated, also require the coil of contactor one, contactor two automatic logical simultaneously
Electricity, automatic power failure.Temperature sensor is put in electrothermal tube babinet, measures the heating temperature in babinet at any time.Need the temperature heated
Degree can be set by the rotating handle of temperature controller, such as setting value is 100 DEG C, when the heating temperature in babinet is less than
At 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, contact
Device one is attracted.When reaching 100 DEG C, electrothermal tube is automatically stopped heating work, and the switch of temperature controller becomes normally opened by normally closed,
The coil blackout of contactor one, contactor one detach.When the heating temperature in babinet is less than 100 DEG C, electrothermal tube starts automatically
Heating work, wind turbine automatic simultaneously will also start air blast, and the coil of contactor two is powered, and contactor two is attracted.When reaching 100 DEG C
When, electrothermal tube is automatically stopped heating work, and wind turbine will also be automatically stopped air blast simultaneously, and the coil of contactor two has a power failure, contactor
Two separation.When contactor one how to be made to be attracted, contactor two is also attracted；When contactor one detaches, contactor two also detaches, we
The method taken is：The coil voltage of the coil, contactor two of choosing contactor one is 220V, with one of power supply 440V
Temperature controller and the coil of contactor one, the coil of contactor two are cascaded, return the another of power supply 440V by line
On root line.In this way, when temperature controller is normally closed, the coil of contactor one, the coil of contactor two are made by the electric current of 220V
Contactor one, contactor two are attracted, and are made the electrothermal tube heating work of 440V, are made the wind turbine rotary work of 380V.When temperature controls
When device is normally opened, the coil of contactor one, the coil of contactor two do not have electric current, so that contactor one, contactor two is detached, make electric heating
Pipe powers off, and stops heating, so that wind turbine is powered off, stop rotating.
Wind turbine is chosen using explosion-proof fan, and when blower fan work contacts 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 contactor one, contactor two with temperature controller, makes electric heater and wind turbine automatically while starting, certainly
It is dynamic to be simultaneously stopped.
2, in addition contactor one, contactor two, volume of transformer are small, light-weight, are mounted on explosion-proof wiring intracavitary, need not be
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.
