Abstract
The utility model discloses a special resistant firebrick of rotary kiln, including firebrick body, firebrick body top intermediate position department is equipped with the semi-circular lug of vertical setting, firebrick body bottom intermediate position is equipped with the semi-circular concave groove of vertical setting, the concave surface size in semi-circular concave groove equals with semi-circular lug's convex surface size. The utility model discloses optimize the special resistant firebrick overall structure of rotary kiln, two resistant firebricks pile up from top to bottom when building by laying bricks or stones, the semi-circular lug that is located on the resistant firebrick body of downside inserts the semi-circular concave groove that inserts on the resistant firebrick body that is located the upside, build by laying bricks or stones through the mortar, build by laying bricks or stones more simple and conveniently and firmly, whole firm intensity and compact type increase, effectively improve resistant firebrick's sealed effect, make the flue gas in the rotary kiln can not permeate the steel sheet through resistant firebrick in, thereby effectively avoid the flue gas to the corruption of rotary.
Description
Technical Field
The utility model belongs to the technical field of resistant firebrick, concretely relates to special resistant firebrick of rotary kiln.
Background
The refractory brick is called fire brick for short, is made of refractory clay or other refractory materials, is light yellow or brown, is mainly used for building smelting furnaces, and can resist high temperature of 1, 580-1 and 770 ℃. Also called fire brick. The refractory material with certain shape and size, the prior art firebrick is generally exclusively used in building of rotary kiln, and the firebrick body needs to bear great temperature variation and heat flux impact in the use, consequently requires the structure closely, and it will guarantee good sealed effect when using, makes the flue gas in the rotary kiln can not permeate the steel sheet through firebrick in to effectively avoid the flue gas to the corruption of rotary kiln body steel sheet, and remain the dust.
However, the refractory bricks in the prior art are all flat three-dimensional block structures, the sealing performance is poor during masonry, and the sealing effect of the refractory bricks cannot be met, so that smoke in the rotary kiln permeates into the steel plate through the refractory bricks, corrodes the steel plate, and influences the service life of the rotary kiln.
Therefore, the special refractory brick for the rotary kiln can effectively improve the sealing effect of the refractory brick, so that smoke in the rotary kiln cannot permeate into a steel plate through the refractory brick, thereby effectively avoiding the corrosion of the smoke to the steel plate of the rotary kiln body and residual dust, effectively ensuring the service life of the rotary kiln, and reducing the production cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a special resistant firebrick of rotary kiln to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the special refractory brick for the rotary kiln comprises a refractory brick body, wherein a longitudinally-arranged semicircular lug is arranged in the middle of the top of the refractory brick body, a longitudinally-arranged semicircular concave groove is arranged in the middle of the bottom of the refractory brick body, and the size of the concave surface of the semicircular concave groove is equal to that of the convex surface of the semicircular lug.
Preferably, the longitudinal length of the semicircular convex block and the semicircular concave groove is equal to the longitudinal width of the refractory brick body.
Preferably, the firebrick body is rectangular.
The utility model discloses a technological effect and advantage: this special resistant firebrick of rotary kiln, overall structure is optimized to special resistant firebrick of rotary kiln, two resistant firebricks pile up from top to bottom and build by laying bricks or stones the time, the semi-circular lug that is located on the resistant firebrick body of downside inserts the semi-circular concave groove that inserts on the resistant firebrick body that is located the upside, build by laying bricks or stones through the mortar, build by laying bricks or stones more simple and conveniently and firmly, whole firm intensity and compact type increase, effectively improve resistant firebrick's sealed effect, make the flue gas in the rotary kiln can not permeate the steel sheet through resistant firebrick, thereby effectively avoid the flue gas to the corruption of rotary kiln body steel sheet.

In the figure: 1. a firebrick body; 2. a semicircular bump; 3. a semicircular concave groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a special resistant firebrick of rotary kiln as shown in fig. 1-2, including refractory brick body 1, refractory brick body 1 top intermediate position department is equipped with the semi-circular lug 2 of vertical setting, refractory brick body 1 bottom intermediate position is equipped with the semi-circular concave groove 3 of vertical setting, the concave surface size of semi-circular concave groove 3 equals with semi-circular lug 2's convex surface size.
Specifically, the longitudinal length of the semicircular convex block 2 and the semicircular concave groove 3 is equal to the longitudinal width of the firebrick body 1.
Specifically, the firebrick body 1 is rectangular.
This special resistant firebrick of rotary kiln, when building by laying bricks or stones, pile up two resistant firebricks from top to bottom and build by laying bricks or stones, the semi-circular lug that is located on the resistant firebrick body 1 of downside inserts and is located the semi-circular concave groove 3 on the resistant firebrick body 1 of upside, build by laying bricks or stones through the mortar, build by laying bricks or stones more simple and conveniently and firmly, whole firm intensity and compact type increase, effectively improve resistant firebrick's sealed effect, make the flue gas in the rotary kiln can not permeate the steel sheet through resistant firebrick, thereby effectively avoid the corruption of flue gas to rotary kiln body steel sheet, and remain.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
