Abstract
The utility model relates to a preformed piece special for a novel dry process cement rotary kiln coal-injection duct head portion. The preformed piece special for the novel dry process cement rotary kiln coal-injection duct head portion comprises a preformed piece body. The preformed piece body is in a shape of a hollow cylinder. The cross section of the preformed piece body is in a round shape. Corundum mullite stones are used as casting materials for the preformed piece body. The preformed piece special for the novel dry process cement rotary kiln coal-injection duct head portion is high in quality, not easy to drop, wear-resistant, washing resistant and long in service life.
Description
Technical field
The utility model relates to a kind of prefabricated component, is specifically related to a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part.
Background technology
At present, the coal injection pipe head special precast part on market is various, but most of service life is shorter, can not realistic work requirements.Most of coal injection pipe head special precast parts easily come off, and material is easily peeled off, thereby need repeated multiple times trimming, to actual production work, bring great inconvenience, the wearability of most of prefabricated component of while, and resistance to impact is poor.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of high-quality is provided, incrust, wear-resisting, resistance to erosion, the new type nonaqueous cement rotary kiln coal powder injection tube head special precast part of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part described in the utility model, it comprises prefabricated part body, described prefabricated part body be shaped as hollow circular cylinder, the cross section of described prefabricated part body is circular, and described prefabricated part body adopts the corundum-mullite castable.
The internal diameter of described prefabricated part body is between 350-550mm.
The external diameter of described prefabricated part body is between 430-630mm.
The length of described prefabricated part body is between 500-800mm.
Beneficial effect: compared with prior art, its remarkable advantage is the utility model: the utility model overall structure is simple, and dimensions meets the requirements, adopt the corundum-mullite castable, improved service life, improved wear-resisting, the abrasion resistance of product simultaneously, product quality is higher.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is cross section structure schematic diagram of the present utility model.
Wherein:
1, prefabricated part body
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, a kind of new type nonaqueous cement rotary kiln coal powder injection tube head special precast part described in the utility model, it comprises prefabricated part body 1, described prefabricated part body 1 be shaped as hollow circular cylinder, the cross section of described prefabricated part body 1 is circular, and described prefabricated part body 1 adopts the corundum-mullite castable; The internal diameter of described prefabricated part body 1 is between 350-550mm; The external diameter of described prefabricated part body 1 is between 430-630mm; The length of described prefabricated part body 1 is between 500-800mm.The utility model overall structure is simple, and dimensions meets the requirements, and adopts the corundum-mullite castable, has improved service life, has improved wear-resisting, the abrasion resistance of product simultaneously, and product quality is higher.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
