Description
Technical Field
The utility model relates to an electric heater unit, specifically speaking are L shape ceramic package electric heater.
Background
In the prior art, for high-temperature heating of a solid particle medium, the medium is usually placed in a heating container and then heated by an external electric heater, and the conventional heating mode mainly has the following problems that on one hand, the conventional general temperature resistance does not exceed 600 ℃, the service life is difficult to guarantee and the high-temperature resistance is poor, on the other hand, the heat transfer efficiency between particles of the solid particle medium is low, so that the large-flow solid particle medium is difficult to heat to a high temperature in a limited heat exchange path, on the other hand, the solid particle medium has high hardness, the flowing medium is difficult to contact and rub with the electric heater for a long time, and the electric heater is difficult to bear the continuous abrasion and is often damaged quickly.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a high temperature resistance can be good, transmission efficiency is high and wear resistance can be good to L shape ceramic package electric heater that can heat up the even heating to the solid particle medium by a wide margin.
In order to solve the technical problem, the utility model discloses a L shape ceramic package electric heater, include the ceramic package and the heat-generating body of setting in the ceramic package inner chamber that the cross sectional shape that comprises vertical section and horizontal segment is L shape, the heat-generating body horizontal reciprocating arrangement in ceramic package inner chamber makes its head and the tail both ends be located vertical section top one side and the horizontal segment afterbody one side of ceramic package respectively, vertical section top side and the horizontal segment afterbody side of ceramic package respectively fixed mounting have with the electrode that wherein one end of heat-generating body is connected.
One part of the heating bodies is transversely arranged in the vertical section of the ceramic shell, and the other part of the heating bodies is transversely arranged in the horizontal section of the ceramic shell.
And a temperature measuring sensor is arranged in the ceramic shell.
The heating body is made of metal materials.
The heating body is an electric heating wire.
The heating wire is in a linear structure or a spiral structure.
The utility model has the advantages that:
its structural design is very simple reasonable, directly adopt ceramic package and design it for L shape cross-section, not only utilized ceramic material itself to make it can bear the high temperature that exceeds 1200 ℃ for a long time from this, and still strengthened structural strength greatly, make electric heater be difficult for the rupture, especially each surface of L shape ceramic package all becomes the heat transfer surface, make heat conduction area maximize, heat conduction efficiency has been improved effectively, can solve the problem that solid particle medium is difficult to the intensification from this well, in addition its ceramic material's high hardness characteristic, the technical problem that electric heater surface bears higher wear resistance for a long time under the high temperature heating operating mode has been solved.

fig. 2 is a schematic side view of the electric heater with L-shaped ceramic shell according to the present invention.
Detailed Description
The L-shaped ceramic case electric heater of the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
As shown in the figures, the L-shaped ceramic shell electric heater of the utility model comprises a ceramic shell 3 which is composed of a vertical section 1 and a horizontal section 2 and has a L-shaped cross section and a heating element 4 which is arranged in the inner cavity of the ceramic shell and used for heating by electrifying, the surface of the ceramic shell 3 can be in a plane or curved surface structure state, the peripheral heat transfer surface of the ceramic shell 3 is used for heat conduction of a heating medium, the heating element 4 can be supported and installed by an insulating support element inside the ceramic shell, an electrode 5 is respectively and fixedly installed at the top side end of the vertical section and the tail side end of the horizontal section of the ceramic shell 3, the electrode 5 is arranged on the same side end surface of the ceramic shell 3, and the ceramic shell is inevitably provided with an L-shaped inner cavity, the heating element 4 is composed of a horizontal main body section and vertical connecting sections which respectively connect the horizontal main body section end to end, as can be seen from figure 1, seen from the front view, the upper half part of the heating element 4 is transversely arranged in the inner cavity of the vertical section left and right (the left and right directions are defined as left and right sides as shown in figure 1), the lower half part of the heating element 4 is transversely arranged in the inner cavity of the vertical section left and right, therefore, the heating element 4 is transversely arranged in the inner cavity of the vertical section and the inner cavity of the horizontal section of the ceramic shell left and right in a reciprocating way, meanwhile, the head end and the tail end of the heating element are respectively positioned on the top side of the vertical section and the tail side of the horizontal section of the ceramic shell, the head end of the heating element 4 is connected on the electrode on the top side of the vertical section of the ceramic shell 3, and the tail end of the heating element 4 is connected on the electrode on the tail side of the horizontal section of the ceramic shell 3.
Further, the heating element 4 is made of a metal material, and the heating element 4 is preferably a heating wire.
Still further, the heating wire 4 is a linear structure, a wave-shaped structure, a plane-shaped structure, a curved surface-shaped structure or a spiral structure, when the heating wire is a wave-shaped structure, a plane-shaped structure, a curved surface-shaped structure or a spiral structure, or the surface area is increased in a limited space or the length is increased in a limited space, so that the power can be improved, the shape change of the heating wire is relieved, and the special effect that the heating wire is not easy to damage is achieved.
