Description

Technical Field

[0001] The utility model belongs to the technical field of kiln masonry, and in particular relates to a high-temperature kiln masonry structure. Background Art

[0002] Industrial high-temperature furnaces are made of high-temperature resistant materials and are widely used in metallurgy, casting, forging and other fields. They are important industrial equipment and require a large amount of heat input. In high-temperature environments, the furnace body material may produce large thermal stress due to thermal expansion and contraction. When a high-temperature furnace is in use, there is usually a layer of insulation material on the outside. The use of insulation material can reduce the thermal stress of the high-temperature furnace body, protect the integrity and stability of the furnace body structure, reduce heat loss, and help the high-temperature furnace use energy more efficiently.

[0003] Existing high-temperature kilns usually build a layer of insulation bricks on the outside of fireproof bricks. The insulation bricks and fireproof bricks are usually built together using refractory materials as adhesives. This method allows heat to be conducted through the solid, reducing the insulation effect. Utility Model Content

[0004] The technical problem to be solved by the present invention is that insulation bricks and fireproof bricks are usually laid together using refractory materials as adhesives. This method allows heat to be conducted through the solid, which reduces the insulation effect of the insulation bricks. In view of the shortcomings of the existing technology, a high-temperature kiln masonry structure is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] It includes refractory bricks, insulation bricks, connecting bricks and connecting insulation bricks. The refractory bricks are laid to form the furnace wall. The connecting bricks are set between two groups of furnace walls. The insulation bricks are laid on the outside of the refractory bricks, and the connecting insulation bricks are laid on the outside of the connecting bricks.

[0007] A mounting groove is provided on one side of the refractory brick, and the mounting grooves of two adjacent groups of the refractory bricks are combined to form an assembly groove. A protrusion is fixedly connected to one side of the insulation brick, and the protrusion is installed inside the mounting groove. The width of the protrusion is greater than the depth of the mounting groove.

[0008] Furthermore, a support bar is fixedly connected to one side of the insulation brick, and the support bar abuts against one side of the refractory brick.

[0009] Furthermore, the angle between the two inner walls of the mounting groove is an acute angle.

[0010] Furthermore, the cross-section of the connecting brick is L-shaped, and a connecting groove is provided on one side of the connecting brick. The connecting groove is combined with the installation groove of the adjacent masonry turn to form an assembly groove. The assembly groove has the same shape as the assembly groove. A connecting protrusion is fixedly connected to one side of the connecting insulation brick, and the connecting protrusion is installed in the connecting groove and the installation groove.

[0011] Furthermore, the shape of the connecting insulation brick is an L-shape that matches the exterior of the connecting brick. A second support bar is provided on one side of the connecting insulation brick close to the corner, and one side of the second support bar abuts against one side of the connecting brick.

[0012] Furthermore, the refractory bricks in the upper layer are arranged alternately with the refractory bricks in the lower layer, and the refractory bricks in the upper layer are used to cover the installation grooves of the refractory bricks in the lower layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. An approximately closed cavity is formed between the insulation bricks and the refractory bricks. This structure uses protrusions to prevent the insulation bricks from contacting the refractory bricks over a large area. Heat enters the cavity through the refractory bricks, reducing the solid contact area and the heat conduction, thereby improving the insulation effect.

[0015] 2. By setting connecting bricks and connecting insulation bricks, a cavity can be formed between the two kiln walls for insulation, avoiding heat loss between the two kiln walls and further improving the insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0022] Example 1: See Figure 1-3 The present embodiment provides a high-temperature furnace masonry structure, comprising refractory bricks 10, insulation bricks 20, connecting bricks 30, and connecting insulation bricks 40. The refractory bricks 10 are sequentially laid together using an adhesive, so that when two refractory bricks 10 are connected together, the mounting grooves 11 thereon combine to form an assembly groove. The refractory bricks 10 are laid together to form furnace walls, the connecting bricks 30 are arranged between the two groups of furnace walls, the insulation bricks 20 are laid outside the refractory bricks 10, and the connecting insulation bricks 40 are laid outside the connecting bricks 30.

[0023] A mounting groove 11 is provided on one side of the refractory brick 10. The mounting grooves 11 of two groups of adjacent refractory bricks 10 are combined to form an assembly groove. A protrusion 21 is fixedly connected to one side of the insulation brick 20. The protrusion 21 is installed inside the mounting groove 11. The width of the protrusion 21 is greater than the depth of the mounting groove 11. The insulation brick 20 is laid close to the refractory brick 10 so that the protrusion 21 is inserted into the mounting groove 11 from above. Since the width of the protrusion 21 is greater than the depth of the mounting groove 11, a nearly closed cavity is formed between the insulation brick 20 and the refractory brick 10. By providing the protrusion 21, the insulation brick no longer contacts the refractory brick 10 over a large area. Heat enters the cavity through the refractory brick 10, reducing the solid contact area and reducing the heat conduction.

[0024] The refractory bricks 10 are staggered and laid on top of the lower refractory bricks 10 using adhesive so that the upper refractory bricks 10 are pressed on the protrusions 21, and finally the top of the refractory brick wall 10 is sealed.

[0025] See Figure 1-3 One side of the insulation brick 20 is fixedly connected with a support bar 22, which abuts against one side of the refractory brick 10. The support bar 22 improves the connection strength between the insulation brick 20 and the protrusion 21. When one side of the insulation brick 20 receives external force, the support bar 22 can prevent the insulation brick 20 and the protrusion 21 from breaking.

[0026] See Figure 1-3The cross-section of the connecting brick 30 is L-shaped. When two vertical kiln walls need to be connected, the connecting brick 30 is used and arranged between the two walls. A connecting groove 31 is provided on one side of the connecting brick 30. The connecting groove 31 is combined with the installation groove 11 of the adjacent masonry turn 10 to form an assembly groove. The assembly groove has the same shape as the assembly groove. A connecting protrusion 41 is fixedly connected to one side of the connecting insulation brick 40. The connecting protrusion 41 is installed in the connecting groove 31 and the installation groove 11. The connecting insulation brick 40 is masonryed on the outside of the connecting brick 30, and the connecting protrusion 41 is inserted into the assembly groove to fix the connecting insulation brick 40 to the connecting brick 30. By arranging the connecting brick 30 and the connecting insulation brick 40, the two kiln walls can also be insulated to prevent heat from being lost between the two kiln walls.

[0027] See Figure 1-3 The shape of the connecting insulation brick 40 is an L-shape that matches the outside of the connecting brick 30. A second support bar 42 is provided on the side of the connecting insulation brick 40 close to the corner. One side of the second support bar 42 abuts against one side of the connecting brick 30. The connecting insulation brick 40 is supported by the second support bar 42. When the side of the connecting insulation brick 40 away from the connecting protrusion 41 is squeezed or impacted, the second support bar 42 can provide supporting force to prevent the connection between the connecting protrusion 41 and the connecting insulation brick 40 from breaking.

[0028] See Figure 1-3 The upper refractory bricks 10 and the lower refractory bricks 10 are arranged alternately. The upper refractory bricks 10 are used to cover the installation grooves 11 of the lower refractory bricks 10. The staggered arrangement can increase the structural strength between the refractory bricks 10. At the same time, covering the installation grooves 11 can reduce the risk of the protrusions 21 being separated from the installation grooves, so that the refractory bricks 10 and the insulation bricks 20 have better integrity.

[0029] Beneficial effects:

[0030] 1. Lay the refractory bricks 10 together in sequence using adhesive so that when two refractory bricks 10 are connected together, the mounting grooves 11 thereon are combined to form an assembly groove. Then, lay the insulation bricks 20 close to the refractory bricks 10 so that the protrusions 21 are inserted into the mounting grooves 11 from above. Then, alternately lay the refractory bricks 10 on top of the lower refractory bricks 10 using adhesive so that the upper refractory bricks 10 are pressed on the protrusions 21. Finally, seal the top of the refractory brick wall 10 after the masonry is completed. Since the width of the protrusions 21 is greater than the depth of the mounting grooves 11, an approximately closed cavity is formed between the insulation bricks 20 and the refractory bricks 10. By setting the protrusions 21, the insulation bricks are no longer in contact with the refractory bricks 10 over a large area. Heat enters the cavity through the refractory bricks 10, reducing the solid contact area, reducing the heat conduction, and improving the insulation effect.

[0031] 2. When two kiln walls need to be connected, use connecting bricks 30 to be set between the two walls, so that the connecting groove 31 and the installation groove form an assembly groove, lay the connecting insulation bricks 40 on the outside of the connecting bricks 30, and insert the connecting protrusions 41 into the assembly groove to fix the connecting insulation bricks 40 to the connecting bricks 30. By setting the connecting bricks 30 and the connecting insulation bricks 40, the two kiln walls can also be insulated, avoiding heat loss from between the two kiln walls and further improving the insulation effect.

[0032] Example 2: Example 2 is a further improvement made on the basis of Example 1, see Figure 1-3 In a high-temperature kiln masonry structure of this embodiment, the angle between the two inner walls of the mounting groove 11 is an acute angle.

[0033] Beneficial effect: the installation groove is set to an acute angle so that the shape of the assembly groove is trapezoidal, which can provide a better anti-pull effect for the protrusion 21 and improve the integrity of the refractory brick and the insulation brick 20.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
