Description

Heat preservation is taken off nail

Technical Field

The utility model belongs to support or positioner field, concretely relates to nail is taken off in heat preservation.

Background

In an industrial boiler, a cement kiln, or a heat-resistant pipeline and other equipment which needs to work in a high-temperature environment, a heat-resistant lining material is required to be added inside the equipment, often in order to protect a metal shell and reduce heat loss. Taking the kiln tail preheater as an important component in cement calcination systems as an example, since the interior of the preheater is at a high temperature during calcination, refractory castable is required to be poured as refractory lining material in many places inside the preheater. When the refractory castable is placed on the inner wall of the cylinder of the preheater, the refractory castable needs to be fixed by using cramps.

The staple of the Y type that adopts at present often or V type structure, it mainly has two problems: 1. the nail is manufactured at the bifurcation by adopting a welding method, which causes the reduction of the nail pulling strength and is easy to cause the accidents of the collapse of refractory lining materials such as refractory castable and the like; 2. because the cramp is often used in a high-temperature environment, due to the principle of thermal expansion and cold contraction, the cramp expands after being heated at high temperature, and the fixed device is easy to crack, so that accidents of collapse of heat-resistant lining materials such as refractory castable and the like are caused.

Therefore, there is a high necessity for a staple which can solve the above technical problems to reduce the occurrence of collapse.

Disclosure of Invention

An object of the utility model is to provide a nail is taken off in heat preservation to solve and take off the problem that the nail is heated inflation.

In order to reach above-mentioned purpose, this scheme provides a nail is taken off in heat preservation, including first stabilizer blade and second stabilizer blade, first stabilizer blade and second stabilizer blade reciprocal anchorage form Y shape, first stabilizer blade and second stabilizer blade are high temperature resistant steel and make, be equipped with on the first stabilizer blade and turn to collude, the heat preservation all is equipped with on the surface of first stabilizer blade and second stabilizer blade, the heat preservation is light high temperature insulation layer.

The light high-temperature heat insulation layer is an alumina heat insulation layer.

The beneficial effect of this scheme lies in: compared with the traditional cramp, the light high-temperature heat-insulating layer in the scheme has good heat-insulating effect, can greatly control the temperature of the cramp and avoid excessive expansion of the cramp; meanwhile, the expansion cushion can play a good role in buffering when expanding. Therefore, the possibility of collapse accidents caused by cracking of the casting material due to thermal expansion of the cramp is effectively reduced.

Further, still include solid fixed ring, gu fixed ring fixes on first stabilizer blade and second stabilizer blade. Through the arrangement of the fixing ring, the fixing strength between the first support leg and the second support leg is strengthened, and the accident that refractory lining materials such as refractory castable collapse can be effectively reduced.

Further, be equipped with the screw thread on first stabilizer blade and the second stabilizer blade, first stabilizer blade, second stabilizer blade and solid fixed ring screw-thread fit. Through screw-thread fit, the installation is easier and the operation is convenient.

Further, still include the third stabilizer blade, the third stabilizer blade is fixed on solid fixed ring. Through rotating solid fixed ring, then the position of adjustable third stabilizer blade, for example rotate the third stabilizer blade to between first stabilizer blade and the second stabilizer blade, then with two dimensions of traditional X, Y axle, change into X, Y, Z's three-dimensional dimension, fixed area increases by a wide margin, and fixed effect is better.

Further, still include the fourth stabilizer blade, the fourth stabilizer blade is fixed on solid fixed ring, and sets up with third stabilizer blade symmetry.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the support comprises a first support leg 10, a crutch hook 11, a second support leg 20, a fixing ring 30, a third support leg 31 and a fourth support leg 32.

Example 1

The present embodiment provides a thermal insulation staple, as shown in fig. 1 and 2, which mainly comprises a first leg 10 and a second leg 20, both made of high temperature resistant steel materials, welded together to form a human-shaped or inverted Y-shape. The turning hook 11 is arranged above the first support leg 10, so that the contact area for fixing can be effectively increased, and the fixing effect is further increased. The surfaces of the first supporting leg 10 and the second supporting leg 20 are both provided with a light high-temperature heat insulation layer, so that the heat insulation effect is good, the excessive expansion of the cramp can be effectively avoided, and the possibility of the buckling accident caused by the heated expansion of the cramp is effectively reduced.

Example 2

The difference between this embodiment and the embodiment is that a fixing ring 30, a third leg 31 and a fourth leg 32 are further added in this embodiment. The fixing ring 30, the third supporting leg 31 and the fourth supporting leg 32 are all made of high-temperature resistant steel materials, and light high-temperature heat insulation layers are arranged on the surfaces of the fixing ring, the third supporting leg and the fourth supporting leg. The third leg 31 and the fourth leg 32 are both welded to the fixing ring 30 and are at 180 ° to each other. Be equipped with the external screw thread on first stabilizer blade 10 and the second stabilizer blade 20, with it matches, be equipped with the internal thread on the solid fixed ring 30, both cooperate each other, can fix solid fixed ring 30 on first stabilizer blade 10 and second stabilizer blade 20.

In addition, each support leg can be provided with a plurality of grooves or bulges so as to increase the contact between the support leg and the heat-insulating layer and ensure that the support leg is fixed more firmly.

When the fixing ring is used, the fixing ring 30 can be rotated according to the actual requirement, so that the connecting line of the third leg 31 and the fourth leg 32 is parallel to or intersected with the connecting line of the first leg 10 and the second leg 20, or a certain angle is generated.

Compared with the traditional cramp, the contact dimension of the cramp and a heat-resistant lining material is increased by the scheme, and the fixing effect is obviously improved. Meanwhile, the light high-temperature heat insulation layer has a good heat insulation effect, the temperature of the cramp can be controlled greatly, and excessive expansion of the cramp is avoided, so that the possibility of collapse accidents caused by heated expansion of the cramp is effectively reduced.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
