Abstract
The invention relates to a jacketed backflow type electric heating device, comprising an heater container having an opening end and a sealed end; the opening end of the heater container is fixedly provided with a heater plug, the sealed end of the heater container is provided with a media outlet; the side wall of the heater container is provided with a media inlet; a vertical electric heating tube bundle is disposed in the heater container; an inner barrel is disposed between the heater container and the electric heating tube bundle; one end of the inner barrel is fixed to the inner wall of the electric heating tube bundle between the media inlet and the media outlet, the other end thereof is vertically extended to the heater plug and is sealed by the end plate of the inner barrel; the electric heating tube bundle is penetrated through the end plate of the inner barrel. The inner barrel is disposed in the heater container of the invention, the flow direction of the media is forced to change by the inner barrel and is simultaneously heated by the inner barrel, the energy source is fully used; after guiding and averaging the media by the inner barrel, the heat exchange is performed with the heating core, the heat exchange is uniform, the heat exchange efficiency is high, and the service life of the heater can be improved.
Description
Technical field
The present invention relates to electric heater, specifically a kind of chuck formula electric heater unit that backflows.
Background technology
Fluid heater is widely used in the industrial manufacture process, adopts the mode of forced convection that gas or liquid are directly heated.Heat medium gets into through the container import, and the heat exchange of medium and heating core is inhomogeneous, and the temperature of container outer wall is higher, and heat loss is also big, to having a negative impact in service life of electric heating equipment, causes the efficiency reduction of firing equipment.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of chuck formula electric heater unit that backflows is provided, this electric heater unit heat exchange is even, the thermal efficiency is high.
According to technical scheme of the present invention: a kind of chuck formula electric heater unit that backflows; The heater container that comprises the sealing of an end opening one end; The openend of said heater container is fixed with the heater end socket; The blind end of said heater container has media outlet, has the medium inlet on the sidewall of said heater container, and the tube bank of electrical heating longitudinally is installed in the said heater container; Be provided with inner core between said heater container and the said electrical heating tube bank; One end of said inner core is fixed on the inwall of the said heater container between said medium inlet and the said media outlet; Its other end extends longitudinally to said heater end socket place and by inner core end plate closes opening, said interior tube end-plate is passed in said electrical heating tube bank.
The openend of said inner core is fixed on through the inner core fixed head on the inwall of said heater container, has a plurality of media on the said inner core fixed head and passes through the hole.
The stiff end of said inner core is provided with the inner core crimping of circular arc.
The heater electrode that links to each other with the electrical heating tube bank is installed on the sidewall of said heater container.
Technique effect of the present invention is: the present invention is provided with inner core in the heater container, and medium is heated by inner core when inner core forces change to flow to, can make full use of the energy; Medium carries out heat exchange with heating core again after the current-sharing of inner core water conservancy diversion, heat exchange is even, and heat exchange efficiency is high, the service life that can improve heater.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1, comprise that heater container 1, inner core 2, electrical heating tube bank 3, media outlet 4, medium inlet 5, interior tube end-plate 6, heater electrode 7, heater end socket 8, inner core fixed head 9, medium are through hole 10, inner core crimping 11 etc.
As shown in Figure 1; The present invention is a kind of chuck formula electric heater unit that backflows, and comprises the heater container 1 of an end opening one end sealing, and the openend of heater container 1 is fixed with heater end socket 8; The blind end of heater container 1 has media outlet 4; Have medium inlet 5 on the sidewall of heater container 1 near media outlet 4, the tube bank of electrical heating longitudinally 3 is installed in the heater container 1, the heater electrode 7 that links to each other with electrical heating tube bank 3 is installed on the sidewall of heater container 1.
The present invention is provided with inner core 2 between heater container 1 and electrical heating tube bank 3.One end of inner core 2 is fixed on the inwall of the heater container 1 between medium inlet 5 and the media outlet 4, and this stiff end is provided with the inner core crimping 11 of circular arc; The other end of inner core 2 extends longitudinally to heater end socket 8 places, and by interior tube end-plate 6 sealing openings, tube end-plate 6 in electrical heating tube bank 3 is passed.Form interlayer between heater container 1 and the inner core 2, constitute jacket type structure.
The openend of inner core 2 is fixed on through inner core fixed head 9 on the inwall of heater container 1, has a plurality of media on the inner core fixed head 9 through hole 10.
The course of work of the present invention is following: medium is compelled to upwards flow behind the interlayer between medium inlet 5 entering heater containers 1 and the inner core 2; And by inner core 2 heating; Turn back downwards in end socket 8 places in the upper end; Get in the electrical heating tube bank 3, after restraining 3 heat exchange, flow out from media outlet 4 with electrical heating.
The present invention is provided with inner core 2 in heater container 1, medium is heated by inner core 2 when inner core 2 forces change to flow to, can make full use of the energy; Medium is limited in not heating part of heating core through the section that turbulent flow will appear in inner core 2 water conservancy diversion; The heating part of medium and heating core carries out efficient heat exchange after the even flow field; Medium is fully taken away the heat that heating core sends, and just can there be localized hyperthermia in the heating section, and heat exchange is even; Can improve the service life and the heat exchange efficiency of heater, energy savings; Under high temperature and high pressure condition, the present invention can effectively reduce the temperature of heater container 1 outer wall, under the same pressure condition bigger allowable stress is arranged, and can effectively reduce the material cost of container outer wall.
