[0006] Preferably, a mounting groove is provided on the metal strip, the heating element is embedded in the mounting groove and fixed by means of temperature-resistant glue.

[0007] Preferably, an explosion-proof wiring tube is installed at one end of the metal strip, and the power line of the heating element is installed in the explosion-proof wiring tube and is connected to a power terminal.

[0008] Preferably, heat-insulating handrails are mounted on the metal strips at the top and bottom.

[0009] Preferably, the heating plate is a tungsten filament ceramic sealed heating plate.

[0010] Preferably, a layer of thermal insulation board is installed on the outside of the metal strip.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention wraps a heating curtain around the pipeline where the blockage occurs, and when the power is turned on, the heating power can be controlled remotely through a distribution box or a mobile phone. The portable heating curtain for thawing blockage is small and flexible, manufactured according to explosion-proof markings, easy to connect and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS
