Description

Technical Field

[0001] The utility model relates to the technical field of refractory bricks, and specifically relates to a refractory brick prefabricated part. Background Technique

[0002] Refractory brick prefabricated parts, also known as refractory precast bricks, are refractory products made of refractory castables. They are usually cast or pressed on-site, then dried or sintered and solidified in the factory, and finally transported to the site for installation. Since refractory brick prefabricated parts have good heat insulation, wear resistance, corrosion resistance, etc. in high-temperature environments, they are important building materials for high-temperature equipment. Currently, refractory brick prefabricated parts are widely used in tunnel kilns, oil refineries, metallurgical industries, etc.

[0003] When traditional refractory bricks are used, such as using refractory bricks to build flues, a large number of refractory bricks will be stacked vertically and fixed by castables. However, in actual use, due to the long-term influence of high temperature on castables, etc., the castables are prone to cracking, and at the same time, due to the self-weight of the refractory bricks, etc., the stacked refractory bricks are prone to collapse. In view of this, we propose a refractory brick prefabricated part. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a technical solution:

[0028] Please refer to Figures 1-5 As shown, a refractory brick prefabricated part includes a support cylinder 1. A plurality of threaded columns 10 are fixed on the outer wall of the support cylinder 1, and nuts 11 are threadedly connected to the outer walls of the threaded columns 10; A plurality of brick bodies 2 are also installed outside the support cylinder 1, and the combined shape of the plurality of brick bodies 2 is annular; Plug blocks 21 are fixed at both side walls of the brick body 2 near one corner. A slot 20 is opened on one side of the plug block 21, and the plug block 21 can be inserted and matched with the adjacent slot 20; Two connecting holes 23 are opened on the outer wall of the brick body 2, and the threaded column 10 passes through the corresponding connecting hole 23; Clamping plates 3 are installed on the outer walls of the brick bodies 2. The clamping plates 3 press against the outer walls of the brick bodies 2. Two fixing holes 31 are opened on the clamping plates 3, the threaded column 10 passes through the corresponding fixing holes 31, and the nut 11 presses against the outer wall of the clamping plate 3.

[0029] In this embodiment, a plurality of positioning grooves 24 are also opened on the outer wall of the brick body 2, and a plurality of positioning blocks 30 are fixed on one side wall of the clamping plate 3 close to the brick body 2, and the positioning blocks 30 are inserted and matched with the corresponding positioning grooves 24. The insertion design of the positioning groove 24 and the positioning block 30 can ensure the accurate alignment between the brick body 2 and the clamping plate 3, avoid misalignment or deviation during the installation process, and improve the stability and assembly efficiency of the overall structure.

[0030] In this embodiment, two heat dissipation grooves 22 are opened on both sides of the outer wall of the brick body 2, and the heat dissipation grooves 22 penetrate the brick body 2. The design of the heat dissipation grooves helps to accelerate the dissipation of heat inside the brick body 2. By effectively dissipating heat, the service life of the brick body 2 can be extended.

[0031] In this embodiment, the overall shape of the brick body 2 is arc-shaped, and the inner wall of the brick body 2 fits against the outer wall of the support cylinder 1. The arc-shaped design enables the brick body 2 to better fit against the outer wall of the support cylinder 1, reduces gaps and voids, and improves the stability of the overall structure.

[0032] In this embodiment, the overall shape of the clamping plate 3 is arc-shaped, and the clamping plate 3 and the positioning block 30 are of an integrally formed structure. The arc-shaped design is conducive to the clamping plate 3 better fitting against the brick body 2, improving the stability of the installation structure, and the integrally formed structure increases the connection reliability between the clamping plate 3 and the positioning block 30.

[0033] In this embodiment, the cross-sectional shape of the support cylinder 1 is annular, and the threaded column 10 is tightly welded to the support cylinder 1. The annular design is beneficial for the support cylinder 1 to provide a better support effect on multiple brick bodies 2, and the tight welding method ensures the connection strength between the support cylinder 1 and the threaded column 10.

[0034] In this embodiment, the brick body 2 and the insertion block 21 are integrally formed structures, and both the brick body 2 and the insertion block 21 are made of refractory materials. The integrally formed brick body 2 and insertion block 21 have better structural strength, ensuring the connection stability between the brick body 2 and the insertion block 21, and thus ensuring the service life of the brick body 2 and the insertion block 21. The selection of refractory materials can ensure the fire resistance of the brick body 2.

[0035] It should be added that the support cylinder 1 in this embodiment is made of stainless steel. Stainless steel not only has the advantages of corrosion resistance and high strength, but also has good high-temperature resistance. It can maintain good mechanical properties and stability in high-temperature environments. Therefore, using this material for the support cylinder 1 ensures the performance and service life of the support cylinder 1.

[0036] During specific use, the user first inserts the connection hole 23 on the brick body 2 onto the threaded column 10. The threaded column 10 then passes through the connection hole 23. At this time, the inner wall of the brick body 2 is in contact with the inner wall of the support cylinder 1. Then, the user inserts the fixing hole 31 onto the threaded column 10. The threaded column 10 then passes through the fixing hole 31. Next, the user tightens the nut 11 on the threaded column 10. The nut 11 then presses against the clamping plate 3, and the brick body 2 is fixedly connected to the support cylinder 1. Finally, the user repeats the above steps and sequentially installs multiple brick bodies 2.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
