Abstract
A rotary kiln cylinder head with an improved structure comprises an equal-diameter cylinder body (1) and a tapered cylinder body (2); the equal-diameter cylinder body is connected with the big end of the tapered cylinder body; square refractory bricks (4) are paved on the inner wall of the equal-diameter cylinder body; special-shaped refractory bricks (3) of which the upper paving surfaces are parallel to the lower paving surfaces and the paving surfaces on the inner sides are larger than those on the outer sides are paved on the inner wall of the tapered cylinder body. The rotary kiln cylinder head has a simple structure, is convenient to manufacture, and avoids a phenomenon that mud falling of refractory mud is frequent, thereby greatly prolonging the service life, lengthening the production period of a rotary kiln, and effectively reducing the production cost.
Description
Technical field
The utility model relates to a kind of rotary kiln, is a kind of structure improved rotary kiln cylinder head specifically.
Background technology
Producing reduced ilmenite is all generally straight body with the whole cylindrical shell of rotary kiln; kiln hood and kiln tail collet are protected cylinder head and collet with building fire clay; but because built fire clay is very thick; in the course of work of rotary kiln; fire clay is short service life; sometimes only have a week just to fall; do not have the effect of protection cylinder head and collet; make cylinder head and collet burn out; if change block refractory brick into; require the thickness of refractory brick very thick, refractory brick is too thick can easily split again and fracture is fallen down, and does not also protect cylinder head and a collet.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, make easily, the structure improved rotary kiln cylinder head of long service life.
A kind of structure improved rotary kiln cylinder head that the utility model provides, it consists of isometrical cylindrical shell and conical shell, isometrical cylindrical shell is connected with the large end of conical shell, at the inwall of isometrical cylindrical shell, build and have square firebrick, at the inwall of conical shell, build and have the heterotypic fire brick that upper and lower face is parallel, face large outer end in inner end is little.
As to improvement of the present utility model, square firebrick aligns with the outer end of heterotypic fire brick joint.
As to further improvement of the utility model, the height of isometrical cylindrical shell is conical shell 0.1～0.2 times.
The utlity model has following advantage:
Simple in structure, novel, make easily.
Change into after pyramidal structure, original fire clay protection cylinder head and the collet of building can be changed into block refractory brick and protecting tin and a collet, avoided fire clay easily to fall the phenomenon of mud.
Make refractory brick thickness attenuation that cylinder head is built, thereby greatly improved refractory brick service life.
Extend the rotary kiln production cycle, effectively reduce production cost.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of structure improved rotary kiln cylinder head that the utility model provides, it consists of isometrical cylindrical shell 1 and conical shell 2, the height of isometrical cylindrical shell is 0.15 times of conical shell, isometrical cylindrical shell 1 is connected with the large end of conical shell 2, at the inwall of isometrical cylindrical shell 1, build and have square firebrick 4, at the inwall of conical shell 2, build and have the heterotypic fire brick 3 that upper and lower face is parallel, face large outer end in inner end is little, square firebrick 4 aligns with the outer end of heterotypic fire brick 3 joints.
As long as the shape of heterotypic fire brick is convenient to every circle according to the tapering of conical shell 2, lays bricks and can; heterotypic fire brick adopts polyvinyl chloride resin slurry to fill with brickwork joint when laying bricks simultaneously; make to be sticked together securely between brick and brick; be not easy to split and fracture is fallen down; cylinder head and collet have effectively been protected; extend the production cycle of rotary kiln, reduce the production cost of reduction titanium.
