Abstract
The invention relates to a heating device for a pipeline, which comprises an outer casing, wherein heating layers, insulating layers and heat preservation layers are arranged inside the outer casing in sequence; the outer casing adopts a split type structure, and is encircled by two semi-circular outer casings connected into a whole through a fastener; circular arc bulges are arranged on the periphery of each semi-circular outer casing; hinge connecting devices are arranged at the two ends of each bulge; the two upper and lower semi-circular outer casings are connected through a hinge. Therefore, the heating device is more fitted with the pipeline, and the heating efficiency is higher.
Description
Technical field
The present invention relates to a kind of pipeline Electric heating appliance, belong to electric heater technical field.
Background technique
Adopt Nie Chrome alloy slice to be applied to the existing production of electric heating panel of electric heater in recent years, its thermal efficiency is high, and thermal inertia is little, quick heating.But it is poor stability in the case of a high temperature, its slab construction not easily fits with the element to be heated of various shape, easily deforms, fracture etc. and affect working efficiency.
The existing a kind of pipeline heating equipment of our company, comprises housing, is provided with zone of heating, isolation layer and thermal insulation layer successively in housing, described in, surrounded by two semicircular shells, linked into an integrated entity by fastening piece.But because pipe diameter is unequal, heating equipment laminating is not tight, finally affects the efficiency of heating surface.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pipeline heating equipment for above drawback, and pipeline of more fitting, the efficiency of heating surface is higher.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of pipeline heating equipment, comprise shell, zone of heating, isolation layer and thermal insulation layer is provided with successively in shell, described shell is split-type structural, is surrounded, linked into an integrated entity by fastening piece by two semicircle shells, wherein, described semicircle shell periphery is provided with the protrusion of circular arc, and described protrusion two ends are provided with hinge joining means, is connected through the hinge between upper and lower two semicircle shells;
Described zone of heating is matched by two heat tapes and is formed, described heat tape, comprise housing, described housing is banded structure, wherein said housing side is upwards provided with some projections, described projection sectional shape is isosceles trapezoid, the electrical heating wire of three distributions triangular in shape is provided with in described projection cavity, described electrical heating wire outer cladding one layer insulating, in described projection cavity, casting epoxy resin is shaped, described housing and lug intersects place are arc-shaped structure, and its radius of arc is r, r=21.5mm.
Above-mentioned a kind of pipeline heating equipment, wherein, the hypotenuse of described projection and housing form angle a, a=28 °.
Above-mentioned a kind of pipeline heating equipment, wherein, the distance L between described projection is 18-36mm.
Beneficial effect of the present invention is:
1. semicircle shell periphery is provided with the protrusion of circular arc, adds the intensity of shell.
2. the housing be connected through the hinge can have certain displacement space, heating equipment is fitted pipeline more, considerably increases the efficiency of heating surface.
3. shell is provided with the projection of isosceles trapezoid, and the distance l between projection is 18-36mm, is provided with electrical heating wire in projection, buckling of shells can not affected the shape of resistance wire, and resistance wire can not be caused to rupture and produce potential safety hazard.
4. the electrical heating wire of Triangle-Profile, structure is the most stable, then pours into a mould with epoxy resin, and stability is better, and meanwhile, epoxy resin has certain elasticity, adds the anti-extrusion performance of antidetonation.
5. housing and lug intersects place are arc-shaped structure, avoid overflexing and heat tape is ruptured, and here, projection two wall serves spacing effect.
6. when using, can by two relative combinationally using of heat tape, heating effect is more remarkable.
