Abstract
The utility model relates to a local heater for electrothermal film pipelines, which is mainly composed of an insulation tile (4), an inner sheath (2), an outer sheath (5), etc., wherein the insulation tile (4) is coated with an electrothermal film which is provided with an energizing loop; the inner wall of the insulation tile (4) is buckled with the inner sheath (2) which is buckled with a pipeline (1) to be heated; the outer wall of the insulation tile (4) is buckled with the outer sheath (5). The utility model is characterized in that the electrothermal film (3) is coated on the inner wall of the insulation tile (4). Compared with the prior art, the utility model can improve thermal efficiency by using two modes of radiation and conduction for the heating pipelines.
Description
The utility model relates to a kind of device that is used for the liquid-transport pipe-line spot heating, particularly pipeline electric heating film heating device.
(patent No.: 95203091.8) " pipeline electric heating film heater " provides a kind of device for heating electric heating membrane that is used for the pipeline heating to Chinese patent, mainly constitute by two blocks of insulating carrier tiles that scribble Electric radiant Heating Film, insulating carrier tile and pipeline fasten, and the power circuit of Electric radiant Heating Film arranged, the metal dust heat-conducting medium is arranged between insulating carrier tile and pipeline, on the insulating carrier tile, be surrounded by housing, be provided with insulating layer between housing and the Electric radiant Heating Film.The defective of this utility model is that Electric radiant Heating Film is coated with the outside that invests insulating carrier, relies on insulating carrier conduction heat energy water back, and energy loss is big, and the thermal efficiency is low.
It is low that the purpose of this utility model provides a kind of energy loss, the Electric radiant Heating Film pipeline local heater that the thermal efficiency is high.
The utility model mainly is made up of insulation tile 4, inner sheath 2, oversheath 5 etc., be coated with Electric radiant Heating Film 3 on the insulation tile 4, Electric radiant Heating Film 3 has power circuit, insulation tile 4 inwalls and inner sheath 2 fasten, inner sheath 2 be heated pipeline 1 and fasten, insulation tile 4 outer walls and oversheath 5 fasten, and its characteristics are that Electric radiant Heating Film 3 is coated on the inwall of insulation tile 4.
Advantage of the present utility model: after being Electric radiant Heating Film 3 placed the inwall of insulation tile 4, can heating to pipeline by radiation and conduction dual mode, thereby improve the thermal efficiency.
Accompanying drawing is the utility model structure chart.
Now in conjunction with the accompanying drawings the utility model is further specified as follows:
As shown in the figure, the utility model, is warded off in the insulation tile 4 with inner sheath 2 and is fastened or use the high temperature insulation glue bond as heater element by the insulation tile 4 of two coated Electric radiant Heating Film 3 of inwall.Be provided with insulating layer or clearance for insulation between Electric radiant Heating Film 3 and the inner sheath 2.Inner sheath 2 be heated pipeline 1 and directly fasten.Insulation tile 4 outer walls are surrounded by isolation layer 8 and oversheath 5.Oversheath 5 is provided with anti-explosion terminal box 6.Limit ear 9 is fastened on heater on the pipeline through bolton.The electrode of Electric radiant Heating Film 3 is fastening and draw through the attachment bolt 7 of insulation tile 4, connects with junction box 6 on the oversheath 5.Be provided with temperature control element in the power circuit of Electric radiant Heating Film 3, temperature automatically controlled to realize.
