Preferably, the first protective layer is formed by laying mineral wool board materials, and the second protective layer is formed by laying perlite board materials.

Preferably, slots are formed in the surfaces of the two sides of the second refractory brick main body, and the first refractory brick main body is matched with the slots arranged on the second refractory brick main body through the insertion blocks and is fixedly inserted in the slots.

Preferably, one side of the first firebrick main body is provided with an engaging groove, and the other side of the second firebrick main body is provided with an engaging part at a position corresponding to the engaging groove.

The utility model discloses a technological effect and advantage:

1. the utility model discloses optimize resistant firebrick component structure, through setting up stratiform mosaic structure and make up into wholly to set up mineral wool board and pearl panel in its inside and strengthen whole fire-resistant protective properties, and can increase whole resistance to compression effect to a certain extent, avoid receiving external factors to influence and appear splitting easily.

2. Optimize resistant firebrick main part structure, two-layer resistant firebrick main part utilizes spacing groove, stopper, inserted block, slot structure to cooperate each other and uses, and through setting up interlock groove and interlock portion for different resistant firebricks are whole can mutually support each other in the assembling process and install, can be with the interlock portion of one side and the corresponding concatenation of interlock groove on another resistant firebrick, can increase certain protection effect.

Description of reference numerals: 1. a first refractory block body; 2. a second refractory block body; 3. a limiting groove; 4. inserting a block; 5. a limiting block; 6. a slot; 7. a first protective layer; 8. a second protective layer; 9. an occlusion groove; 10. an occlusion part.

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 double-deck resistant firebrick that rotary kiln used as shown in fig. 1-2, including first resistant firebrick main part 1 and second resistant firebrick main part 2, spacing groove 3 has been seted up to the bottom both sides of first resistant firebrick main part 1, and first resistant firebrick main part 1 is equipped with inserted block 4 in the both sides surface symmetry formula of spacing groove 3, and the surperficial both sides homogeneous body shaping of second resistant firebrick main part 2 has spacing block 5.

The first protective layer 7 and the second protective layer 8 are sequentially laid on the surface of the second refractory brick main body 2, the first protective layer 7 is formed by laying a mineral wool board material, and the second protective layer 8 is formed by laying a perlite board material. The mineral wool board has light weight and high temperature resistance, can play a good auxiliary protection effect, and is matched with the perlite board material to form a layered protection structure, so that the protection performance of the double-layer refractory brick structure is further improved.

The first firebrick main body 1 and the second firebrick main body 2 are spliced and formed, and the limiting groove 3 is correspondingly contacted with the limiting block 5.
