TECHNICAL FIELD

[0001] The utility model belongs to refractory brick technical field, concretely relates to a hanging refractory brick. BACKGROUND

[0002] The hanging refractory brick is mainly used to meet the needs of industrial kiln and high-temperature industrial field. These fields are characterized by high temperature, high pressure and strong chemical corrosion, so they have strict requirements on the performance of refractory materials. The design of the hanging refractory brick is to adapt to these harsh working conditions, and the refractory brick is fixed in the furnace body by a metal hanging part to withstand expansion and shrinkage under high temperature. At present, the hanging refractory brick used in industry is mostly connected with a connecting piece at the top end of the refractory brick, and then the refractory brick is hoisted, but connecting a connecting piece at the top end may result in poor structural stability of the refractory brick. In a high-temperature environment, the refractory brick may generate a large stress due to thermal expansion and cold shrinkage, which may cause the connecting piece to loosen or break, thereby affecting the fixing effect of the refractory brick. Therefore, whether a hanging refractory brick capable of improving structural stability and durability can be provided is a technical problem to be solved by the utility model. SUMMARY

[0003] To solve the above technical problems, the utility model provides a hanging refractory brick.

[0004] The utility model discloses a hanging refractory brick adopts the technical scheme that:

[0006] Further, a second reinforcing steel bar is through-formed on the second through hole, a third through hole is through-formed at the middle position of the second reinforcing steel bar, a first reinforcing steel bar is through-formed at the second through hole, and the middle of the first reinforcing steel bar is out of the third through hole of the second reinforcing steel bar.

[0007] Further, the two ends of the second reinforcing steel bar and the two ends of the second reinforcing steel bar are respectively provided with external threads.

[0008] Further, the top end and the bottom end of the second reinforcing steel bar are respectively provided with a blocking block, the blocking block is a stepped column structure, the blocking block comprises a first block body and a second block body arranged in an axial direction, and a first threaded hole is arranged in the axial direction on the blocking block.

[0009] Further, the recessed portions of the plurality of arc-shaped clamping grooves on the brick body are the same as the protruding portions of the plurality of arc-shaped clamping blocks, and the plurality of arc-shaped clamping grooves and the plurality of arc-shaped clamping blocks are symmetrically arranged on the two sides of the brick body.

[0010] Further, arc-shaped storage grooves are symmetrically and vertically arranged on the first side surface and the second side surface of the brick body; the bottom ends of the two storage grooves are respectively connected to the two ends of the first through hole, and the top ends of the two storage grooves are open structures.

[0011] Further, one end of the first reinforcing steel bar is connected with an L-shaped connecting rod; an L-shaped through hole is arranged in the middle of the L-shaped connecting rod in a penetrating manner, and the two ends of the L-shaped connecting rod are open structures; internal threads are arranged at the two open ends of the L-shaped connecting rod; and one end of the first reinforcing steel bar is threadedly connected with one end of the L-shaped connecting rod.

[0012] Further, the other end of the L-shaped connecting rod is threadedly connected with a third reinforcing steel bar, the third reinforcing steel bar is arranged on the storage groove, and the top end of the third reinforcing steel bar is arranged to pass out of the upper end of the storage groove.

[0015] The beneficial effects of the present application are as follows:

[0016] By transversely inserting a plurality of reinforcing steel bars in the refractory bricks, the transverse stability of the refractory bricks can be enhanced. The reinforcing steel bars can effectively disperse and transfer loads, and reduce damage to the refractory bricks caused by load concentration. Meanwhile, by vertically inserting a reinforcing steel bar in each brick body, the compressive strength and overall stability of the refractory bricks can be increased, and deformation of the refractory bricks in the vertical direction can be prevented.

[0017] Enhanced seismic performance, the addition of steel bars can significantly improve the seismic performance of firebricks. In the case of earthquakes or other vibrations, steel bars can absorb and consume part of the energy, reduce the vibration amplitude of firebricks, and thus protect firebricks from damage. This is particularly important for industrial kilns located in earthquake-prone areas or that need to withstand frequent vibrations.

[0018] Improved durability, the presence of steel bars can improve the durability of firebricks. In a long-term high-temperature environment, firebricks may gradually age or be damaged. Reinforcement with steel bars can delay this process and increase the service life of firebricks. In addition, steel bars can also prevent cracks in firebricks due to temperature changes, further improving their durability.

[0019] Convenient installation and maintenance. By inserting steel bars in firebricks, the installation process can be simplified. Steel bars can serve as positioning and fixing aids, making the installation of firebricks more accurate and secure. During maintenance, if damage to firebricks is found, the function can be restored by replacing or repairing steel bars without the need to completely replace firebricks, which not only saves costs but also reduces downtime.

[0028] As shown in Figures 1-4 A hanging refractory brick comprises a brick body.

[0029] Four arc-shaped clamping grooves 3 are formed on the first side surface 1 of the brick body, and four arc-shaped clamping blocks 4 are formed on the second side surface 2 of the first brick body. The first side surface 1 and the second side surface 2 are the plane opposite to the first side surface 1 on the brick body. The recessed parts of the four arc-shaped clamping grooves 3 are the same as the protruding parts of the four arc-shaped clamping blocks 4, and the four arc-shaped clamping grooves 3 and the four arc-shaped clamping blocks 4 are symmetrically arranged on both sides of the brick body.
