Problems solved by technology
Existing thermal insulation hooks are usually "L" shaped hooks bent from round steel. The hooks are made of metal materials with a relatively large thermal expansion coefficient after heating, and the thermal insulation material is usually aluminum silicate fiber felt or lightweight Insulation castables have a relatively small expansion coefficient after being heated. During the long-term operation of the boiler, they are constantly in the state of alternating heat and cold. The thermal insulation hooks usually expand in the length direction after being heated, which leads to cracking or even peeling off of the insulation material. The loss of heat will increase the operating cost of the boiler, and the service life of the insulation layer will be shorter

Embodiment Construction
[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0014] Such as figure 1 As shown, the present invention is bent into an "L" shape by round steel, including a nail bar section 1 and a nail hook section 3. The nail bar section 1 is provided with a corrugated section 2, and the corrugated section 2 can change the length direction of the nail bar section 1. The expansion of the nail rod section 1 is expanded in sections, and the expansion coefficient in the length direction is reduced, thereby reducing the damage of the hook nail to the insulation material. The corrugated section 2 is arranged in the middle of the nail bar section 1. In order to make the corrugated section 2 effectively reduce the expansion coefficient in the length direction, thereby reducing the damage of the hook nail to the insulation material, the length of the corrugated section 2 is at least as lon...

The invention relates to a heat insulation hook nail. The heat insulation hook nail is used for supporting a heat insulation layer of a boiler and is characterized in that the heat insulation hook nail is made by bending round steel into a T-shaped structure. The heat insulation hook nail comprises a nail rod segment and a nail hook segment, wherein a corrugated segment is arranged at a central part of the nail rod segment. By arranging the corrugated segment at the nail rod segment, expansion of the nail rod segment is changed in a length direction for reduction of a coefficient of expansion in the length direction, and thereby damage of the heat insulation material caused by the heat insulation hook nail is reduced; cracking or even stripping of the heat insulation material is avoided; heat loss is reduced; boiler operation cost is reduced; and service life of the heat insulation layer is prolonged.
Description
technical field [0001] The invention relates to a supporting component of a boiler insulation layer, in particular to a heat insulation hook used for supporting the boiler insulation layer. Background technique [0002] A large number of heat preservation hooks are required in the heat preservation areas of the boiler wall, the large shell of the furnace roof, the boiler shell, the header and the tube bundle, etc., to support the heat preservation material of the boiler heat preservation layer. Existing thermal insulation hooks are usually "L" shaped hooks bent from round steel. The hooks are made of metal materials with a relatively large thermal expansion coefficient after heating, and the thermal insulation material is usually aluminum silicate fiber felt or lightweight Insulation castables have a relatively small expansion coefficient after being heated. During the long-term operation of the boiler, they are constantly in the state of alternating heat and cold. The therm...
