Abstract

A kiln ball-top articulation brick belongs to the spare parts or appurtenances field of the kiln, in particular to a complicated shape brick used for the kiln. The kiln ball-top articulation brick comprising a brick body is characterized in that the brick body comprises an upper block and a lower block, wherein the border of a cross section of each block is composed of the intersection between a curve and a line segment intersect, the other cross section which is vertical to the cross section is rectangular, curve portion of the upper block of the brick body and the lower block of the brick body can be combined with each other convexly and concavely, and is capable of rotating relatively. The kiln ball-top articulation brick of the utility model is capable of prolonging service life of kiln, and has the advantages of low cost of manufacture and use, and convenience for manufacture, thereby the utility model is convenient for extension and application and can be widely applied to various kilns.

Description

Joint, kiln ball top brick

Technical field

The utility model belongs to the parts or the field of accessories of kiln, relates in particular to a kind of kiln quarl.

Background technology

Make the needs of integrated cost along with the development of modern kiln production Technology with for reducing product, to having higher requirement the service life of kiln.Because the thermal deformation direction of ball top type kiln top and kiln side wall is different, make in shearing force of both joint portion existence, frequent variation (heating up and cooling) along with temperature in the stove, the kiln of this joint portion is known from experience generation to be destroyed, influence the service life of whole kiln, press for a kind of fire-proof material member that can eliminate that kiln top and kiln side wall produce owing to the thermal deformation direction is different in the actual production the destruction of kiln body.

The utility model content

Technical problem to be solved in the utility model provides a kind ofly can eliminate the destruction to the kiln body that kiln top and kiln side wall produce owing to the thermal deformation direction is different, can prolong kiln body joint, the kiln ball top brick in service life effectively.

The technical solution of the utility model is: joint, a kind of kiln ball top brick is provided, comprises the brick body, it is characterized in that the brick body comprises upper and lower two, a limit in a cross section of every brick body is made of curve and line segment intersection; Becoming another cross section of brick body of an angle of 90 degrees with aforementioned cross section is rectangle; The curved portion of upper and lower two brick bodies convex-concave each other cooperates, and upper and lower brick body can rotate relatively.

A wherein said limit of going up a cross section of brick body is made of the curve and the line segment intersection that protrude; A described limit in a cross section of brick body down is made of recessed curve and line segment intersection.

Its described cross section is the longitudinal cross-section of brick body.

Its described curve is a circular arc line.

The contact rate of the curved portion of its described upper and lower two brick body sections is 30% ~ 80%.

Compared with the prior art, the utility model has the advantages that:

1. owing to can rotate relatively between the upper and lower brick body, ball top type kiln top and the destruction that the kiln side wall produces owing to the thermal deformation direction is different can be eliminated effectively, the service life of kiln body can be prolonged greatly the kiln body.

2. manufacturing cost and use cost is low, and manufacturing, easy to process is easy to be extended and applied.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is the longitudinal cross-section structural representation of brick body under the utility model;

Fig. 2 is the longitudinal cross-section structural representation of brick body on the utility model;

Fig. 3 is the utility model actual user mode schematic diagram of brick body up and down.

The specific embodiment

Among Fig. 1, a limit of the longitudinal cross-section of following brick body 7 is intersected by recessed circular arc line 1 and line segment 2,3 and is constituted, and its middle conductor 2,3 can be in a plane, also can be not in a plane, all the other limits are made of line segment 4,5 and 6, and wherein the radius of circular arc line is not less than 50mm.

Among Fig. 2, a limit of the longitudinal cross-section of last brick body 14 is intersected by circular arc line 8 that protrudes and

line segment

9,10 and is constituted, and its

middle conductor

9,10 can be in a plane, also can be not in a plane, all the other limits are made of

line segment

11,12 and 13, and wherein the radius of circular arc line is not less than 50mm.

Among Fig. 3, with spherical kiln top portion joining go up brick body 14 and with circular arc line (curved surface) part 1 and 8 of the joining brick body 7 down of kiln side wall part each other convex-concave cooperate, can rotate relatively between the two brick bodies, the contact rate of the curve of upper and lower two brick body sections (curved surface) part is 30%～80%, thereby can dissolve ball top type kiln top and the infringement that the kiln side wall produces owing to the thermal deformation direction is different effectively, prolong the service life of kiln body effectively the kiln body.

The utility model can prolong the service life of ball top type kiln furnace kiln body effectively, and its manufacturing cost and use cost is low, and manufacturing, easy to process is easy to be extended and applied, and can be widely used in various kilns.
