Abstract
A kind of heater is the utility model is related to, specifically immersion electric heater.It includes tube sheet and the electric heating tube no less than two U-shapeds, and electric heating tube one end corresponding to U-shaped opening portion both passes through tube sheet and electric heating tube is integrally in collection pencil arrangement, and the end of the electric heating tube is uniformly connected on a controller.It is characterized in that the centre of the electric heating tube in collection pencil arrangement is provided with overheat protector, the overheat protector is connected by wire with the controller.The electric heating tube of the immersion electric heater middle part is not easy overheat and burnt, and service life is longer.
Description
Technical field
A kind of heater is the utility model is related to, specifically fluid medium is added by the way of contact is immersed
Heat, the immersion electric heater of heating.
Background technology
Immersion electric heater is a kind of device that electric heater is immersed in liquid and is heated, heated up.Oil,
In the field such as chemical industry and metallurgy, in order to improve the thermal efficiency, while reduce the volume of device, immersion electric heater as far as possible again
Often all using the structure of more electric heating tube boundlings.However, electric heating tube can cause electric heating tube density in collection pencil distribution
Increase, peripheral electric heating tube have surrounding medium continually to absorb heat, and the heat of the electric heating tube of central interior be not easy by
Take away so that the heat skewness of this immersion electric heater, the electric heating tube overheat for easily causing centre are burnt, shadow
Ring the service life of electric heater.
Utility model content
Problem to be solved in the utility model is to provide a kind of immersion electric heater, the immersion electric heater pars intermedia
The electric heating tube of position is not easy overheat and burnt, and service life is longer.
To solve the above problems, take following technical scheme：
Immersion electric heater of the present utility model includes tube sheet and the electric heating tube no less than two U-shapeds, U-shaped opening portion
Corresponding electric heating tube one end both passes through tube sheet and electric heating tube is integrally unified in collection pencil arrangement, the end of the electric heating tube
It is connected on a controller.It is characterized in that the centre of the electric heating tube in collection pencil arrangement is provided with overheat protector, should
Overheat protector is connected by wire with the controller.
Further improvement of the utility model scheme is that have supporting plate in the middle part of the electric heating tube, in collection pencil arrangement
Electric heating tube is unified through the supporting plate, and both are in be fixedly connected.The overheat protector is fixed in the supporting plate.Using
Supporting plate fixes electric heating tube and overheat protector, can improve the rigid of the immersion electric heater, makes it more stable,
It is hardly damaged.
Such scheme is taken, there is advantages below：
Because immersion electric heater of the present utility model is in the centre setting of the electric heating tube in collection pencil arrangement
There is overheat protector, the overheat protector is connected by wire with the controller.When in use, when there is heat skewness
Even, when the electric heating tube temperature at center is too high, overheat protector can detect high temperature signal, and cut off electricity in time by controller
Heating tube power supply, stop heating.Hereafter, the electric heating tube heat in centre just can slowly be diffused into circumferential periphery, and by
Absorption of Medium.When the temperature of electric heating tube is reduced to safety value, controller connects electric heating tube power supply again, and electric heating tube recovers
Normal work.Therefore, the immersion electric heater can by overheat protector protect centre electric heating tube, avoid its by
Burnt in overheat, the service life of immersion electric heater can be greatly prolonged.
Brief description of the drawings
Fig. 1 is the structural representation of immersion electric heater of the present utility model.
Embodiment
The utility model is described in further details below in conjunction with accompanying drawing.
As shown in figure 1, immersion electric heater of the present utility model includes tube sheet 2 and the electrical heating no less than two U-shapeds
Pipe 3, one end of electric heating tube 3 corresponding to U-shaped opening portion both passes through tube sheet 2 and electric heating tube 3 is overall in collection pencil arrangement, the electricity
The end of heating tube 3 is uniformly connected on a controller 1.It was provided with the centre of the electric heating tube 3 of collection pencil arrangement
Thermal protector 5, the overheat protector 5 are connected by wire with the controller 1.
In order to improve the rigid of the immersion electric heater, make it more stable, be hardly damaged.The present embodiment is in institute
The middle part for stating electric heating tube 3 is additionally provided with supporting plate 4, and the electric heating tube 3 in collection pencil arrangement is unified through the supporting plate 4, and
Both are in be fixedly connected.The overheat protector 5 is fixed in the supporting plate 4.
In use, the immersion electric heater is inserted in fluid media (medium) to be heated.Under normal heating state, control
Device 1 connects the power supply of electric heating tube 3, and electric heating tube 3 converts electrical energy into heat energy and passes to fluid media (medium), fluid media (medium) is heated up.
After a period of time is heated, heat situation pockety necessarily occurs inside and outside the electric heating tube 3 in collection pencil arrangement.When
When the temperature of electric heating tube 3 of center is too high, overheat protector 5 can detect high temperature signal, and be cut in time by controller 1
The power supply of heating tube 3 is powered off, stops heating, is burnt so as to protect the electric heating tube 3 in centre not overheat.Hereafter, central part
The heat of electric heating tube 3 of position just can slowly be diffused into circumferential periphery, and by Absorption of Medium.When the temperature of electric heating tube 3 reduces
During to safety value, controller 1 connects the power supply of electric heating tube 3 again, and electric heating tube 3 recovers normal work.
