Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal insulation bricks, and specifically discloses a lightweight thermal insulation brick special for an aluminum melting furnace. Background Art
[0002] The aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed according to the aluminum smelting process. Insulation bricks need to be stacked inside it to reduce heat loss.
[0003] Most of the existing insulation bricks are square structures. When they are stacked inside an aluminum melting furnace, the gaps between adjacent insulation bricks are relatively large, so a sufficient amount of mortar needs to be filled for sealing. The mortar is compacted by the gravity of the insulation bricks between each layer in the horizontal direction, but the insulation bricks cannot be completely in contact with each other in the vertical direction. Even if mortar is used for filling, holes are likely to appear inside the mortar, resulting in poor overall insulation effect of the insulation bricks. At the same time, the mortar cannot be continuously poured between each layer of insulation bricks, resulting in the insulation bricks being unable to be tightly connected by the mortar, and the overall structural stability is poor. Utility Model Content
[0004] In view of the above-mentioned defects or shortcomings in the prior art, the present application aims to provide a lightweight insulating brick specially used for aluminum melting furnaces, comprising an insulating brick body designed with an arc structure, a protrusion being provided on one side of the insulating brick body, and a groove matching the protrusion being provided on the other side of the insulating brick body, and two arc notches being provided inside the insulating brick body.
[0005] Preferably, an asbestos pad is provided on the side of the insulation brick body close to the groove, and a positioning groove is provided on the outer arc surface of the insulation brick body.
[0006] Preferably, a boss adapted to the asbestos pad is provided on the side of the insulation brick body.
[0007] Preferably, the arc groove runs through the interior of the insulation brick body, and the arc groove serves as a pouring port for mortar, and the insulation brick body is stacked in a staggered distribution manner between each layer.
[0008] Beneficial effects:
[0009] 1. The lightweight insulation bricks specially used for the aluminum melting furnace can seal the gaps formed by vertical stacking of the insulation bricks through asbestos pads. Even if holes appear inside the mortar, the mortar in the vertical direction can be sealed under the extrusion of the asbestos pads by the adjacent insulation bricks. At the same time, by stacking the insulation bricks in a staggered distribution, the asbestos pads can be squeezed by the gravity of the insulation bricks themselves, further improving the overall insulation effect of the insulation bricks.
[0010] 2. The lightweight insulation bricks specially used for the aluminum melting furnace use the arc groove as the pouring port of the mortar, so that the mortar between each layer of insulation bricks can be poured continuously, so that the insulation bricks can be tightly connected by the mortar, and the overall structural stability is relatively high.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.
[0019] See also Figure 1-4 A lightweight thermal insulation brick specially used for an aluminum melting furnace comprises a thermal insulation brick body 1 designed with an arc structure, and the thermal insulation brick body 1 adopts this structure to reduce the gap between adjacent thermal insulation bricks, a protrusion 2 is arranged on one side of the thermal insulation brick body 1, and a groove 3 matched with the protrusion 2 is opened on the other side of the thermal insulation brick body 1, through the coordinated use of the protrusion 2 and the groove 3, the thermal insulation bricks can limit themselves between each layer after stacking, ensuring that the thermal insulation bricks are not prone to collapse and skew, and two arc notches 4 are opened inside the thermal insulation brick body 1, and the arc notches 4 can reduce the overall weight of the thermal insulation brick.
[0020] Among them, an asbestos pad 5 is arranged on the side of the insulation brick body 1 close to the groove 3, and a positioning groove 6 is opened on the outer arc surface of the insulation brick body 1. The positioning groove 6 can be used to position the insulation brick for reference, so that during the stacking process of the insulation bricks, personnel can use the positioning groove 6 as a reference to stack the insulation bricks in a staggered distribution.

[0022] Among them, the arc groove 4 runs through the interior of the insulation brick body 1, and the arc groove 4 serves as a pouring port for mortar. The insulation brick body 1 is stacked in a staggered distribution between each layer. The insulation bricks are stacked in this way so that the arc grooves 4 between each layer of insulation bricks can be connected, so that the mortar can be poured layer by layer through the arc groove 4, ensuring that the mortar can be cast and formed as a whole inside the arc groove 4.
[0023] When stacking the insulation bricks, mortar is applied to the bottom and two sides of the insulation brick body 1, and the sides of the asbestos pad 5 do not need to be coated with mortar. The adjacent insulation brick bodies 1 are connected and laid continuously through the protrusions 2 and the grooves 3, and the mortar is poured on the insulation bricks of the first layer through the arc notch 4.
