[0002] High-alumina bricks are a type of refractory material primarily used for lining blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary kilns. They are formed and calcined from bauxite or other raw materials with a high alumina content. The production process for high-alumina bricks is similar to that for high-clinker clay bricks. Currently, kilns require cooling after firing, but current cooling efficiency is low and urgently needs improvement. Utility Model Content

[0003] The purpose of the utility model is to provide a kiln for firing high-alumina bricks, which is used to solve the problem of low cooling efficiency of existing kilns for firing high-alumina bricks.

[0004] In order to solve the above problems, the utility model provides a kiln for firing high-alumina bricks, comprising an outer furnace body and an inner furnace body, a cooling assembly is provided between the outer furnace body and the inner furnace body, the cooling assembly comprises a first hollow cooling box symmetrically arranged up and down and a second hollow cooling box symmetrically arranged left and right, the first hollow cooling box and the second hollow cooling box are connected to each other through a connecting pipe, the top of the outer furnace body is fixedly provided with a water inlet pipe connected to one of the first hollow cooling boxes, and the bottom of the outer furnace body is fixedly provided with a water outlet pipe connected to the other first hollow cooling box.

[0005] The utility model provides a kiln for firing high-alumina bricks, which also has the following technical features:

[0006] Furthermore, the lengths of the first hollow cooling box and the second hollow cooling box are the same as the length of the inner furnace body.

[0007] Furthermore, the height of the second hollow cooling box is equal to the height of the inner furnace body.

[0008] Furthermore, the connecting pipe is in an "L" shape.

[0009] Furthermore, the number of the connecting pipes is 4.

[0010] Furthermore, the side walls of the first hollow cooling box or the second hollow cooling box away from the inner furnace body are fixedly connected to the inner wall of the outer furnace body.

[0011] The utility model has the following beneficial effects: after the high-alumina bricks are fired, cold water is injected into the first hollow cooling box above the inner furnace body by connecting the water inlet pipe with the water pump, and the water in the first hollow cooling box enters the second hollow cooling boxes on both sides through the connecting pipe, and then the water in the second hollow cooling box enters the second hollow cooling box below the inner furnace body through the connecting pipe below, thereby quickly cooling the inner furnace body from different directions so that the staff can take out the fired high-alumina bricks. BRIEF DESCRIPTION OF THE DRAWINGS
