Abstract
The utility model relates to a pawing nail which is used for supporting insulating layers of various high-temperature furnace bodies, such as boilers, garbage incinerators and the like. The pawing nail is characterized by comprising a V-shaped nail body, wherein a V-shaped bottom section vertical to the plane of the V-shaped nail body is arranged at the lower part of the V-shaped nail body; an extending section parallel to the plane of the V-shaped bottom section is arranged at the upper end of the V-shaped nail body; and the V-shaped nail body, the V-shaped bottom section and the extending section form an integral structure. The V-shaped bottom section is arranged at the lower part of the V-shaped nail body, and the extending section is arranged at the upper part of the V-shaped nail body, so that the V-shaped bottom section is firmly welded on the surface of the boiler body to ensure that the insulating layers are firmly supported, the service life of the insulating layers is prolonged, and the loss of the heat energy is reduced.
Description
Technical field
The utility model relates to a kind of boiler accessories, especially relates to a kind of bitch, is used for the support of the heat-insulation layer of high temperature bodies of heater such as various boilers, incinerator.
Background technology
At present, various boilers, the heat-insulation layer of high temperature bodies of heater such as incinerator adopts mostly at body of heater outer surface ramming, the cast refractory heat-insulating is moldable, high-temperature flame-proof mud etc., after operation under the long term high temperature vibration, avoid producing cracking and come off in order to guarantee heat-insulation layer, guarantee the service life of heat-insulation layer, moldable at the cast refractory heat-insulating, before the high-temperature flame-proof mud, body of heater outer surface welding V type bitch, because the structural limitations of V type bitch, the bottom of V type bitch can only be welded on the body of heater surface with the form of a contact, contact area is little, under long-term bad working environments, work, pad is easier to fracture, and bitch is come off, thereby makes heat-insulation layer take place to ftracture and crackle occurs, not only influence the life-span of heat-insulation layer, and can cause a large amount of heats to run off.
The utility model content
The applicant has carried out research and has improved at above-mentioned problem, and a kind of bitch is provided, can be firm in the boiler furnace surface soldered, guarantee firm support to heat-insulation layer, and prolong the life-span of heat-insulation layer, reduce the loss of heat.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of bitch comprises " V " staple body, and section at the bottom of " V " shape is established in described " V " staple body bottom, and section is vertical with the plane of described " V " staple body at the bottom of described " V " shape; Described " V " staple body upper end is provided with extension, described extension and section plane parallel at the bottom of " V " shape; Described V " section and described extension constitute integrative-structure at the bottom of staple body and described " V " shape.
Further:
The angle of described " V " staple body is identical with the angle of section at the bottom of described " V " shape.
The angle of described " V " staple body is between 40 °～90 °.
The angle of section is between 30 °～120 ° at the bottom of " V " shape.
Technique effect of the present utility model is:
The disclosed a kind of bitch of the utility model, section at the bottom of the bottom of " V " staple body is provided with " V " shape, at V " top of staple body is provided with extension; and section is firm in the boiler furnace surface soldered at the bottom of making " V " shape; guarantee the firm support to heat-insulation layer; prolong the life-span of heat-insulation layer, reduces the loss of heat.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, 3, the utility model comprises " V " staple body 1, section 2 at the bottom of " V " shape is established in " V " staple body 1 bottom, section 2 is vertical with the plane of " V " staple body 1 at the bottom of " V " shape, " V " staple body 1 upper end is provided with extension 3, the plane parallel of section 2 at the bottom of extension 3 and " V " shape, V " staple body 1 and section 2 at the bottom of " V " shape and extension 3 formation integrative-structures.Between 40 °～90 °, the included angle B of section is usually between 30 °～120 ° at the bottom of " V " shape usually for the included angle A of " V " staple body 1.In the present embodiment, the included angle A of " V " staple body 1 is identical with the included angle B of section 2 at the bottom of " V " shape, is 60 °.
When making the utility model, earlier round steel is bent into " V " structure, and the two ends bending is gone out two extensions 3, section 2 at the bottom of the bottom bending of " V " structure goes out " V " shape can be finished the making of bitch then.When carrying out the bitch welding, section 2 at the bottom of " V " shape is welded on the body of heater outer surface, like this, can make bitch soldering furnace external surface securely, increase the bonding area of bitch and body of heater outer surface, thereby guarantee firm support heat-insulation layer.
Claims (4)
