Abstract
The utility model relates to a novel anchor nail which is mainly applicable to single-layer and double-layer heat isolating wear resistant liner. The anchor nail comprises a fixing and connecting plate, an anchor ring and wing hooks on the anchor ring, and is characterized in that the anchor ring is orthohexagonal; each side wall face of the anchor ring is provided with wing hooks in pair, wherein, one of the wing hooks extends towards the outer side of the anchor ring and the other extends towards the inner side of the anchor ring, i.e. the inner and the outer wing hooks are staggered at intervals. The novel anchor nail can improve the overall quality of the liner and the firmness of the liner; meanwhile, the anchor nail is particularly applicable to the partial overhaul to equipments with liner, and is characterized by simple and reasonable structure design, strong firmness, convenience in construction, extension of the use cycle of the liner, etc.
Description
Technical field
The utility model relates to a kind of novel anchor nails, and it mainly is applicable in the single, double layer insulating and wearing-resistant lining, belongs to equipment supplementary structure spare technical field in the oil refinery band village.
Background technique
In the catalytic cracking unit of oil refining industry sedimentation again dirt device, external heat exchanger, carry pleased surface of equipment such as fall way and reaction-regeneration system delivery pipe, be lined with the lining that refractory material and skeleton constitute.Existing with layer lining structure in, usually adopt cylindricality nail, end plate, hexsteel to make skeleton, cylindricality tack welding is connected on the internal surface of equipment, end plate is welded in the top of cylindricality, after having constructed, insulated lining again hexsteel and end plate are welded, ramming is poured into a mould the material of anti-the wear resistance lining in the tortoise plastron mesh, though this structure makes lining have certain compression strength.But this structure collectivity steadiness is totally relatively poor, the construction more complicated, and especially the joint of hexsteel is easy to cracking under the condition of high temperature, causes the hexsteel bulge, causes lining to come off, thereby has influenced the normal operation of device.For monolithic lining is the integrated structure, and the embryo in case the part lining comes off can't local replacing, needs monolithic lining is destroyed replacing, therefore causes the increase of the long and maintenance cost of the service cycle of equipment.China's utility model patent 200420074723,8 discloses a kind of anchor nails, although its using effect is better, because it is provided with three notches, processing technology complexity.
The model utility content
The purpose of this utility model provides that a kind of steadiness is strong, easy to maintenance, long service life and the simple novel anchor nails of processing technology.
For realizing that the technological scheme that the purpose of this utility model is taked is: this novel anchor nails comprises the hamulus on fixed connecting plate, anchoring circle and the anchoring circle, it is shaped as regular hexagon to it is characterized in that described anchoring circle, on each limit wall of anchoring circle, be respectively arranged with hamulus, this hamulus is to be provided with in pairs, one of them hamulus is to the lateral expansion of anchoring circle, another hamulus is to the medial expansion of anchoring circle, and promptly inside and outside hamulus is interval-staggered.
The utility model is equipped with positioning screw in the center portion of described fixed connecting plate, and this positioning screw and fixed connecting plate are by being threaded.
Use this anchor nails to make the insulating and wearing-resistant lining skeleton, can improve the total quality of lining, increase the soundness of lining, this anchor nails is specially adapted to equipment local overhauling in the belt material simultaneously.Compare with existing multiple lining anchor nails, this anchor nails has the structural design advantages of simple, and steadiness is strong, easy construction, the characteristics such as life cycle that can prolong lining; And it is compared with Chinese utility model patent 200420074723,8, and its manufacturability is better, processes simple and convenient.

Embodiment
Referring to Fig. 1--Fig. 3, anchor nails of the present utility model is made of anchoring circle 1, hamulus 2, positioning screw 3 and fixed connecting plate 5, anchoring circle 1 be shaped as regular hexagon.The limit wall of anchoring circle 1 is provided with hamulus 2, and this hamulus 2 is to be provided with in pairs, and one of them hamulus 2 is to the lateral expansion of anchoring circle 1, and another hamulus 2 is to the medial expansion of anchoring circle 1, and promptly inside and outside hamulus 2 is interval-staggered.In order to satisfy the requirement that the different-thickness lining is installed, be welded with a fixed connecting plate 5 at an end of anchoring circle 1, positioning screw 3 is equipped with in the center portion of this fixed connecting plate 5, and this positioning screw 3 and fixed connecting plate 5 are by being threaded.This structure is applicable to the dual-layer lining and the single-layer lining of the heat insulation and wearing layer of having of all thickness.Positioning screw 3 and fixed connecting plate 5 are not set, when having only anchoring circle 1 and hamulus 2 in the structure, applicable to lining with individual layer thermal-protective coating on anchoring circle 1.
In use, anchor nails 1 rule is at regular intervals arranged, form latticed skeleton, in the grid that anchor nails 1 forms, nexine is a thermal-protective coating the pouring material ramming of lining, and skin is wearing layer (those skilled in the art can be understood), tamping flattens, hamulus 2 on the anchoring circle 1 stretches out the hole and the notch that stay can make anchoring circle 1 inside and outside lining be interconnected to constitute an integral body, and makes lining more firm by hamulus 2 with combining of lining, has also increased the intensity of lining simultaneously.
Claims (2)
1, a kind of novel anchor nails, comprise the hamulus on fixed connecting plate, anchoring circle and the anchoring circle, it is characterized in that: it is shaped as regular hexagon described anchoring circle, on each limit wall of anchoring circle, be respectively arranged with hamulus, this hamulus is to be provided with in pairs, one of them hamulus is to the lateral expansion of anchoring circle, and another hamulus is to the medial expansion of anchoring circle, and promptly inside and outside hamulus is interval-staggered.
2, novel anchor nails according to claim 1, it is characterized in that: positioning screw is equipped with in the center portion at described fixed connecting plate, and this positioning screw and fixed connecting plate are by being threaded.
