Description

Technical Field

[0001] The utility model relates to refractory bricks for a heating furnace and a disassembly tool, in particular to refractory bricks for a detachable cantilever roller and a disassembly tool. Background Art

[0002] The heating furnace's loading and discharging sides must have installation and inspection holes for cantilever rollers. After the cantilever rollers are installed, there will be a large gap between the cantilever roller neck and the furnace body. During normal production, flames may overflow from the hole, causing a great impact on the on-site environment and surrounding equipment.

[0003] In studying the existing technology, the inventors found that disposable refractory bricks are used to seal the holes on site during production, and the roller neck bricks are manually broken when repairing and replacing equipment. The broken roller neck bricks are easy to fall into the furnace body, increasing the labor intensity of the workers and the difficulty of cleaning. The broken roller neck bricks cannot be reused, which increases production costs.

[0004] Therefore, there is an urgent need for a refractory filler that is easy to disassemble and reusable. Summary of the Invention

[0005] In order to overcome the problem in the prior art that refractory bricks are difficult to remove or require violent crushing, resulting in residues that are difficult to clean, a refractory brick designed with a disassembly portion and a special disassembly tool is proposed.

[0009] The deflection cavity is a cavity perpendicular to the insertion hole. After the insertion hole cross section enters the deflection cavity space, it can rotate at an angle greater than fifteen degrees.

[0010] Further,

[0011] The deflection cavity is cylindrical, and the diameter of the cylinder is greater than or equal to the cross-sectional length of the insertion hole.

[0012] Further,

[0034] The technical solutions in the embodiments are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0035] In order to overcome the problem in the prior art that refractory bricks are difficult to remove or require violent crushing resulting in residues that are difficult to clean, a refractory brick designed with a disassembly portion and a special disassembly tool is proposed.

[0036] See also Figures 1 to 6 , this specific embodiment is: a refractory brick for a detachable cantilever roller, comprising:

[0037] The brick body 100 is a C-shaped brick made of refractory material. A plurality of brick bodies 100 can be assembled into a truncated cone or a cylinder with a hollow cylindrical body having a through axis. Figure 1 and Figure 6 When the wall through which the cantilever roller passes is cylindrical, the bricks 100 are assembled into a cylinder; when the wall is truncated, the bricks 100 are assembled into a truncated cone. Figure 6 In the example, the bricks 100 are truncated cone-shaped. It should be noted that the purpose of assembling multiple bricks 100 is to facilitate removal. In the present embodiment, there are two bricks 100, and the two bricks 100 can be arranged in an up-down or left-right arrangement. Since the bricks 100 are C-shaped, i.e., an arched structure, the multiple bricks 100 can also be arranged in a truncated cone or cylinder without the aid of external forces.

[0038] The brick body 100 is provided with one or more disassembly parts 200, and the disassembly parts 200 include:

[0039] The insertion hole 210 is a channel with a long cross-section extending vertically from the surface of one end of the brick body 100 to the interior of the brick body 100;

[0040] The deflection cavity 220 is a cavity perpendicular to the insertion hole 210 . After the cross section of the insertion hole 210 enters the deflection cavity 220 , it can rotate at an angle greater than fifteen degrees.

[0041] The number of disassembly parts 200 is often determined by the difficulty of disassembly or to facilitate removal in the event of a broken brick body 100. The direction of insertion into hole 210 is generally parallel to the cantilever roller passage hole 300, and the deflection cavity 220 only needs to allow the specialized tool to penetrate deeply enough for deflection, allowing for natural removal. Of course, it should also be considered that the deflection cavity 220 does not necessarily need to be located at the end of the brick body 100; it can also be located within the inner cavity. Placing it at the end can, of course, reduce the difficulty of removing the brick body 100.

[0042] See also Figure 2 For convenience, the special tool can be deflected in any direction, or deflected to a position perpendicular to the hole 210. In some embodiments,

[0043] The deflection cavity 220 is cylindrical, and the diameter of the cylinder is greater than or equal to the cross-sectional length of the insertion hole 210 .

[0044] See also Figure 1 and Figure 4 ,

[0045] The C-shaped brick body 100 has a protrusion at one end and a groove at the other end. When assembled, the protrusions and grooves of two adjacent brick bodies 100 fit together. The concave-convex fit can improve the overall stability of the assembled bricks.

[0046] In some embodiments, see Figure 4 , preferably,

[0047] There are two brick bodies 100.

[0048] See also Figure 5 In some embodiments, because the reserved channel is a truncated cone, it needs to fit the outer wall size.

[0049] The frustum formed by assembling a plurality of brick bodies 100 is connected along the axis of the frustum to form a new frustum-shaped structure, and the generatrix of the new frustum-shaped structure is a straight line.

[0050] In this embodiment, a special disassembly tool is designed to match the disassembly part 200. Figure 3 , a disassembly tool for refractory bricks for a detachable cantilever roller, comprising:

[0051] The deflection portion 410 is a rod or stick having a length smaller than the cross-sectional length of the insertion hole 210;

[0052] The connecting portion 420 is a rigid component perpendicular to the deflecting portion 410 and having a length greater than the length of the insertion hole 210;

[0053] The gripping portion 430 is a rigid component fixedly connected to the connecting portion 420 and located at the other end relative to the deflecting portion 410 .

[0054] In some embodiments, in order to facilitate the completion of the human grasping and deflection action, preferably,

[0055] The gripping portion 430 is an annular structure.

[0056] Specific operation: In the channel that needs to be filled, multiple bricks 100 are filled layer by layer along the channel radial direction. During the filling process, the insertion holes 210 on the bricks 100 are facing outwards to facilitate subsequent disassembly.

[0057] The removal tool 400 is inserted deeply into the insertion hole 210. The deflection portion 410 at the end of the removal tool 400 enters the deflection cavity 220 and deflects at an angle, which can also be perpendicular to the insertion hole 210. In this case, the deflection portion 410 is blocked by the deflection cavity 220 and can be manually pulled out to complete the removal. When restoration is required, the intact removable cantilever roller can be reinstalled with refractory bricks.

[0058] The beneficial effects compared with the prior art are: by setting a disassembly part 200 on the refractory bricks and using a special disassembly tool 400 for disassembly and assembly, the labor intensity of workers is reduced, the labor productivity is improved, and the refractory bricks can be reused, achieving the effect of reducing costs and increasing efficiency.

[0059] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
