Heat shrink sleeve heating device

Abstract

The invention discloses a heat shrinking sleeve heating device, and belongs to the field of pipeline equipment. The heat shrinking sleeve heating device comprises a tubular main body frame. An infrared heater is arranged on the inner side of the main body frame. The two ends of the main body frame are each provided with a plurality of windproof assemblies. The multiple windproof assemblies arranged at any end of the main body frame are distributed in a circumferential array mode with the axis of the main body frame as the axis center. Each windproof assembly comprises a windproof blade. The areas of openings in the end faces of the main body frame can be decreased through the windproof blades. The multiple windproof assemblies which are distributed in the circumferential array mode with the axis of the main body frame as the axis center are arranged at the two ends of the heat shrinking sleeve heating device, and the areas of the openings in the end faces of the main body frame are decreased through the windproof assemblies, so that the problems that in relevant techniques, gaps exist between the two ends of a heat shrinking sleeve heating device and a heat shrinking sleeve, and the heating effect of an infrared heater on the heat shrinking sleeve can be affected by the gaps when air in the outside environment flows violently are solved. The heating effect of the heat shrinking sleeve heating device is improved.

Description

technical field [0001] The invention relates to the field of pipeline equipment, in particular to a heat shrinkable sleeve heating device. Background technique [0002] Pipeline joints are anti-corrosion structures at the welds of two sections of oil or gas pipelines, and heat-shrinkable sleeves are generally used as joint materials. During construction, the heat-shrinkable sleeve can be wrapped on the welded part of the pipe, and then the surface of the heat-shrinkable sleeve can be evenly heated to make the heat-shrinkable sleeve shrink evenly along the radial direction of the pipe. At the same time, the inner layer of the heat-shrinkable sleeve is melted. The high-quality colloid is filled and coated on the pipeline to form a firm and sealed outer anti-corrosion layer of the pipeline. [0003] In the related art, there is a heat-shrinkable sleeve heating device, which includes a tubular main frame, and an infrared heater is arranged inside the main frame for heating the ...
