Description

Technical Field

[0001] The utility model relates to the technical field of refractory bricks, in particular to a refractory brick for boiler masonry. Background Art

[0002] Due to the special characteristics of boilers operating in high temperature and high pressure environments, boilers, as key equipment for energy conversion, need to withstand extremely high temperatures and pressures inside their furnaces. Therefore, strict requirements are placed on the high temperature resistance, wear resistance, and thermal insulation properties of the furnace walls. Refractory bricks are widely used in the construction of boiler furnace walls due to their excellent high temperature resistance, corrosion resistance, and compressive strength.

[0003] However, the prior art still has the following problems:

[0004] First of all, when traditional refractory bricks used for boiler masonry are stacked, there is often a problem that the bricks are not tightly connected and are easy to loosen or fall off. This defect is particularly obvious in high-temperature environments, affecting the high-temperature resistance and operational safety of the boiler.

[0005] Secondly, in the existing boiler masonry process, the connection between the refractory bricks is often not strong enough, resulting in insufficient overall structural stability. In addition, because the sides of the refractory bricks are too smooth, the masonry process is more complicated.

[0006] In view of the above problems, the inventors proposed a refractory brick for boiler masonry to solve the above problems. Utility Model Content

[0009] Preferably, a plurality of snap blocks are fixedly provided on one side of the brick body, a plurality of snap grooves are opened on one side of the brick body, and the snap blocks cooperate with the snap grooves to prevent sliding. Chiseled patterns are fixedly provided on both sides of the brick body, and chiseled grooves are opened on both sides of the brick body for use with the two chiseled patterns respectively. The chiseled grooves and the chiseled patterns can facilitate bonding between the bricks during construction.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figure 1-3As shown, the utility model provides a refractory brick for boiler masonry, including a brick body 1, a plurality of protrusions 20 are fixedly provided at the upper and lower ends of the brick body 1, a plurality of grooves 21 are opened at the upper and lower ends of the brick body 1, two limiting plates 23 are fixedly provided at the lower end of the brick body 1, and two limiting grooves 24 are opened at the upper end of the brick body 1. When the refractory bricks need to be stacked, the two brick bodies 1 are fitted together up and down so that the inner surface of the groove 21 can be limited on the outer surface of the protrusion 20, and the limiting groove 24 can cooperate with the limiting plate 23 for limiting, thereby further improving the stability of the refractory bricks when stacking.

[0020] A pin hole 22 is commonly provided at one end of the opposing surface of each protrusion 20 and groove 21. The inner surfaces of the multiple grooves 21 are respectively fitted with the outer surfaces of the multiple protrusions 20, and the inner surfaces of the two limiting grooves 24 are respectively fitted with the outer surfaces of the two limiting plates 23. The multiple protrusions 20 and the multiple grooves 21 are alternately distributed at the upper and lower ends of the brick body 1. The brick body 1 can be further fixed by inserting steel bars or other materials into the interior through the pin hole 22 after stacking. The protrusion 20 can be limited on the inner surface of the groove 21 through the groove 21, and the limiting plate 23 can be limited on the inner surface of the limiting groove 24 through the limiting groove 24. The alternating distribution of the protrusions 20 and the grooves 21 can effectively improve the friction during stacking.

[0021] A plurality of snap-fitting blocks 30 are fixedly provided on one side of the brick body 1, a plurality of snap-fitting grooves 31 are opened on one side of the brick body 1, chiseled patterns 33 are fixedly provided on both sides of the brick body 1, and chiseled grooves 32 are opened on both sides of the brick body 1 for use with the two chiseled patterns 33 respectively. When the brick body 1 needs to be spliced, adhesive material is applied on the chiseled patterns 33 and chiseled grooves 32 on one side of the two brick bodies 1. The adhesive material can be easily hung on the chiseled patterns 33 and chiseled grooves 32, which is convenient for bonding after splicing. Then, the snap-fitting blocks 30 are snapped into the snap-fitting grooves 31, so that the spliced brick body 1 is not prone to sliding.

[0022] There are three engaging blocks 30 and three engaging grooves 31, and the three engaging blocks 30 and the three engaging grooves 31 are distributed at equal intervals on both sides of the brick body 1. The outer surfaces of the multiple engaging blocks 30 are respectively fitted with the inner surfaces of the multiple engaging grooves 31. Three hollow cavities 34 are jointly opened on both sides of the brick body 1, and the three hollow cavities 34 are linearly distributed on both sides of the brick body 1. The equal intervals between the engaging blocks 30 and the engaging grooves 31 can effectively improve the stability of the engagement. The engaging blocks 30 can be limited on the inner surface of the engaging grooves 31 through the engaging grooves 31. The brick body 1 can reduce the weight of the brick body 1 while saving manufacturing materials through the hollow cavities 34.

[0023] Working principle: When the refractory bricks need to be stacked, the two brick bodies 1 are placed up and down so that the inner surface of the groove 21 can be limited by the outer surface of the protrusion 20. At the same time, the limiting groove 24 can cooperate with the limiting plate 23 to limit the position, further improving the stability of the refractory bricks when stacking;

[0024] After stacking, the brick body 1 can be further fixed by inserting steel bars or other materials into the interior through the pin hole 22. The protrusion 20 can be limited on the inner surface of the groove 21 through the groove 21. The limiting plate 23 can be limited on the inner surface of the limiting groove 24 through the limiting groove 24. The alternating distribution of the protrusions 20 and the grooves 21 can effectively improve the friction during stacking.

[0025] When the brick bodies 1 need to be spliced together, adhesive material is applied to the chiseled lines 33 and the chiseled grooves 32 on one side of the two brick bodies 1. The adhesive material can be easily attached to the chiseled lines 33 and the chiseled grooves 32, making it easier to bond the brick bodies 1 together. Then, the snap-fitting blocks 30 are snapped into the snap-fitting grooves 31, making it less likely for the spliced brick bodies 1 to slip.

[0026] The equal spacing of the locking blocks 30 and the locking grooves 31 can effectively improve the stability of the locking. The locking blocks 30 can be limited on the inner surface of the locking grooves 31 through the locking grooves 31. The brick body 1 can reduce the weight of the brick body 1 while saving manufacturing materials through the hollow cavity 34.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
