Abstract

The utility model discloses a heater for a pipeline, comprising a heating wire and an insulating heat-insulating ring. The heating wire is arranged in the insulating heat-insulating ring; the insulating heat-insulating ring is designed to be a ring structure; and the heating wire surrounds on the inner periphery of the insulating heat-insulating ring. The utility model greatly reduces heat loss, leads more heat energy to be transferred to a subject which is to be heated, can fast heat up the pipeline at an ideal temperature with low power, and greatly saves time, labor and energy cost, so as to improve production efficiency and reduce production cost. By using an insulating felt, the utility model not only effectively reduces the heat lose but also effectively isolates a heating body from a shell to lead the use of products to be more safer.

Description

Pipeline heater

Technical field

The utility model relates to a kind of pipeline heater.

Background technique

For faster, better, the heating to required object of safety, the thermal loss in the minimizing heating process of maximum possible reduces unnecessary energy waste and reduces production costs etc.;

Original product is only by simply going here and there the heating of electric heating wire implementation to heating object in ceramic hole, because the simple coarse of processing technology, thermal loss is bigger in heating process, rate of heating is slow, factors such as power consumption is many, and product is not easy to fix, and electric wire is exposed and cause the efficiency of heating surface low, use inconvenience, and dangerous.Simultaneously, owing to there is not temperature controlling device, causing can only be to the rough heating of heating object, can not accomplish that temperature controls more accurately.

The model utility content

Technical problem to be solved in the utility model provides a kind of pipeline heater, and this heater is to pipeline efficiency of heating surface height, and rate of heating is fast.

For solving the problems of the technologies described above, technological scheme provided by the utility model is: a kind of pipeline heater, include heating wire, insulation heat insulation loop, and heating wire is located in the insulation heat insulation loop, described insulation heat insulation loop is made as cirque structure, and described heating wire is looped around on the inner peripheral surface of insulation heat insulation loop.

Described insulation heat insulation loop is that the ring segment of arc surrounds by at least two cross sections, is that hinge connects between described ring segment is adjacent.

Described pipeline heater also includes annular outer cover and heat resistance fiber felt layers, and described insulation heat insulation loop is located in the shell, and described heat resistance fiber felt layers is located between insulation heat insulation loop and the shell.

Described annular outer cover radially is provided with two-layer, and internal layer is filled described insulation heat insulation loop, the described heat resistance fiber felt layers of outer filling.

The inwall of described annular outer cover is provided with through hole.

The equal mode for cloth of described heating wire be made as walk abreast back bending around.

Described heating wire is a serial or parallel connection formula Placement.

The advantage that the utlity model has: reduce the loss of heat in the ceramic heating external body by covering one deck insulation felt as much as possible, by ceramic tenminal block receiving on the plug with security wire, in stainless overcoat of the whole threading of product, make product be difficult for moving, and reduce the temperature that the people can touch case surface greatly, use more safe.

The reduction that this product is bigger thermal loss, make heat more pass to heating object, small-power, fast by temperature control can be heated to that desirable temperature has been saved the time greatly, manpower and energy cost, reduced cost of production thereby improved the efficient of producing.Use by the insulation felt has not only effectively reduced thermal loss, and make done between heating unit and shell effectively see every, it is just safer that product is used.

Description of drawings:

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a schematic cross-section of the present utility model.

Embodiment:

A kind of pipeline heater as shown in Figure 1, include heating wire 4, insulation heat insulation loop 3, heat resistance fiber felt layers 2 and annular outer cover 1, heating wire 4 is coated in the insulation heat insulation loop 3, and insulation heat insulation loop 3 is located in the annular outer cover 1, and heat resistance fiber felt layers 2 is located between insulation heat insulation loop 3 and the shell 1.

Insulation heat insulation loop 3 is made as cirque structure.(the insulation heat insulation loop is the 3 and 3 ' ring-type that surrounds, and annular outer cover is the 1 and 1 ' ring-type that surrounds) that the ring segment that insulation heat insulation loop 3 and annular outer cover 1 are arc by two cross sections surrounds; Be that hinge 5 connects between ring segment is adjacent; Corresponding heating wire 4 is formed by connecting for multistage serial or parallel connection formula, and every section walks abreast back bending in each ring segment.

Annular outer cover 1 radially is provided with two-layer, and internal layer is filled described insulation heat insulation loop 3, the described heat resistance fiber felt layers 2 of outer filling.The inwall 11 of annular outer cover 1 is provided with the through hole (not marking among the figure) of being convenient to heat transfer.

Electric heating wire is imported in the pottery with holes, length and width according to design are in advance arranged, in order better to reduce thermal loss, around the ceramic heat circle, fill with felt, external plug is used to connect, temperature for better control heater heating is together in series circuit with a mechanical temperature detect switch (TDS), so that control the temperature of integral heater by the temperature of temperature detect switch (TDS) bottom impression; After the heater mounted inside is finished the casing inside of all packing into; carry out the general assembly work of last shell aspect; by reserving good screw on the riveted joint mesochite; its each parts that originally assembled in casing inside are in the metastable environment; put at last be used for heat insulation and the protection shell finish last installation; protection product inside is reduced the bump degree as far as possible, also avoids the too high scald of skin temperature user of service simultaneously.
