Description
Technical field
The utility model relates to a kind of cement manufacture plant, specifically, relates to a kind of kiln cyclone preheater inner core.
Background technology
Cement kiln cyclone preheater is the raw material preheating device in the middle of cement producing line, at present, no matter its inner core is integral solder form or burst suspension type, mostly use the special alloy Steel material of heat-resistant antifriction, expensive, and due to the characteristic of residing environment and metal itself, cause it perishable, service life is short, needs often to change, improve production cost, increase business burden.
Summary of the invention
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides the kiln cyclone preheater inner core of a kind of Wear-resistant, high-temperature resistant, anticorrosive, long service life.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of kiln cyclone preheater inner core, comprise metal cylinder, the inwall of described metal cylinder is welded with in netted metal wire layer, the inwall of described metal wire layer is provided with the ceramic lacing film of arc and the contiguous block for being connected ceramic lacing film, the left side wall of described ceramic lacing film and right side wall are provided with outward extending T-shaped projection, the left side wall of described contiguous block and right arm are provided with the T-shaped groove that opening matches outwardly and with the T-shaped projection of ceramic lacing film, described ceramic lacing film be socketed T-shaped projection by T-shaped groove between contiguous block and be connected, the positive sidewall of described ceramic lacing film leaves wavy wind guide tank, the installing hole running through ceramic lacing film is left in the corner, front of described ceramic lacing film, described ceramic lacing film surface scribbles coating boron nitride film layer.
Further illustrate, the inner chamber of described metal wire layer evenly leaves groove.
Compared with prior art, the utility model has following beneficial effect: this preheater inner barrel, and the net metal silk layer of the welding on metal cylinder can make ceramic material more firm in the surface attachment of metal cylinder.Ceramic lacing film is adopted to be socketed by groove the structure that projection is connected with between contiguous block; make to reach seamless link between ceramic lacing film and contiguous block; thus make ceramic lacing film connect closely; be conducive to protection cylindrical shell not corroded; extend the service life of cylindrical shell; adopt the structure of wavy wind guide tank, high-temperature tail gas is reduced the scouring force of ceramic lacing film, extends the service life of ceramic lacing film.There is coating boron nitride film layer on pottery lacing film surface, improves the oxidation resistance of material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection domain of the present utility model and range of application:
As shown in Figure 1, Figure 2 and Figure 3, a kind of kiln cyclone preheater inner core, comprise metal cylinder 1, the inwall of described metal cylinder 1 is welded with in netted metal wire layer 2, the inner chamber of described metal wire layer 2 evenly leaves groove 8, the effect of groove 8 arrives cylindrical shell 1 to cushion heat, reduces the etching extent of cylindrical shell 1, increases the service life.The inwall of described metal wire layer 2 is provided with the ceramic lacing film 3 of arc and the contiguous block 11 for being connected ceramic lacing film 3, the left side wall of described ceramic lacing film 3 and right side wall are provided with outward extending T-shaped projection 4, the left side wall of described contiguous block 11 and right arm are provided with the T-shaped groove 5 that opening matches outwardly and with the T-shaped projection 4 of ceramic lacing film 3, described ceramic lacing film 3 be socketed T-shaped projection 4 by T-shaped groove 5 between contiguous block 11 and be connected, the positive sidewall of described ceramic lacing film 3 leaves wavy wind guide tank 6, the installing hole 7 running through ceramic lacing film 3 is left in the corner, front of described ceramic lacing film 3, described ceramic lacing film 3 surface scribbles coating boron nitride film layer.
This preheater inner barrel, the net metal silk layer 2 of the welding on metal cylinder 1 can make ceramic material more firm in the surface attachment of metal cylinder 1.Ceramic lacing film 3 is adopted to be socketed by groove 5 structure that projection 4 is connected with between contiguous block 11; make to reach seamless link between ceramic lacing film 3 and contiguous block 11; thus make to connect closely between ceramic lacing film 3; be conducive to protection cylindrical shell 1 not corroded; extend the service life of cylindrical shell 1; adopt the structure of wavy wind guide tank 6, high-temperature tail gas is reduced the scouring force of ceramic lacing film 3, extends the service life of ceramic lacing film 3.There is film plating layer on pottery lacing film 3 surface, and film plating layer selects coating boron nitride film layer, can form, surface anticorrosion with firing after 1 μm of boron nitride micro mist paste coating, anti-oxidant, improves the oxidation resistance of material.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make some equivalent alternative or obvious modification without departing from the concept of the premise utility; and performance or purposes identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
