Description

Technical Field

[0001] The utility model relates to the technical field of anode baking furnaces, in particular to a composite furnace roof for the flue wall of an anode baking furnace. Background Technique

[0002] The main structure of an anode baking furnace is that a baking material box is formed by a flue wall and a cross wall. A furnace roof is connected above the flue wall. The green anode blocks and filling coke are loaded into the material box. Under the condition of being isolated from air, the green anode products in the material box are indirectly heated by the high-temperature flue gas in the flue wall.

[0003] The furnace roof in the prior art has a layered structure from top to bottom. The lower structure is in contact with high-temperature flue gas and flames, and the upper structure is for heat preservation. In this method, the casting cost of the furnace roof is relatively high. Moreover, since one end of the lower structure is in contact with the flue wall and the other end faces are exposed, the lower structure is prone to heat loss from both sides, causing the temperature inside the flue wall to change. Content of the Utility Model

[0004] Aiming at the technical problems existing in the background technique, the purpose of the utility model is to provide a composite furnace roof for the flue wall of an anode baking furnace, which not only has relatively high strength, but also can keep heat, and is relatively convenient to install during the installation process.

[0024] Embodiment

[0025] As Figures 1-5 shown, a composite furnace roof for the flue wall of an anode baking furnace includes a casting body Ⅰ 1, a casting body Ⅱ 2 and a support member 3. The casting body Ⅰ 1 is connected to the support member 3 and connected into a T shape. There are at least two casting bodies Ⅱ 2, which are respectively arranged in the groove on both sides of the casting body Ⅰ 1. The casting body Ⅰ 1, the casting body Ⅱ 2 and the support member 3 are combined into a rectangle. The casting body Ⅰ 1 is cast with high-strength casting material, and the casting body Ⅱ 2 is cast with heat-insulating casting material. The position of the casting body Ⅰ 1 is the position of the flame in the flue wall. Casting with high-strength casting material can not only ensure fire resistance and high temperature resistance, but also improve the strength of the overall structure. The casting body Ⅱ 2 is on both sides of the casting body Ⅰ 1 and is cast with heat-insulating casting material, which can reduce the temperature loss of the exposed part of the composite furnace roof and enhance the baking efficiency of the anode baking furnace.

[0026] As Figure 1 、 2As shown in FIGS. 4, the support member 3 includes an annular baffle 31 and a pull-ring assembly disposed inside the annular baffle 31. The number of the pull-ring assemblies is the same as that of the casting body II 2. The pull-ring assembly includes a plurality of support rods 32 and a support ring 33. The support rods 32 are fixedly disposed inside the annular baffle 31, and the support ring 33 is lapped between adjacent support rods 32. The annular baffle 31 is connected to the upper end of the casting body I 1, and the pull-ring assembly passes through the inside of the casting body I 1, extends from the lower end of the casting body I 1, and is connected into the casting body II 2. Different materials are used for the casting body I 1 and the casting body II 2 during casting. After the support member 3 is designed, the connection between the casting body I 1 and the casting body II 2 is made more firm, avoiding the disconnection of the connection surface.

[0027] As Figure 2 , 5 shown, a plurality of mating grooves I 101 and a plurality of mating grooves II 102 are provided at the lower end of the casting body I 1. The mating grooves I 101 and the mating grooves II 102 are vertically arranged. A plurality of mating grooves III 201 and a plurality of mating grooves IV 202 are provided at the lower end of the casting body II 2. After the casting body I 1 and the casting body II 2 are connected, the mating grooves I 101 and the mating grooves III 201 are aligned, and the mating grooves II 102 and the mating grooves IV 202 are aligned. There are a plurality of protrusions on the existing flue wall. The mating grooves are designed so that when the composite furnace roof is placed on the flue wall, the protrusions of the flue wall can be embedded into the mating grooves, making the connection between the composite furnace roof and the flue wall more stable and preventing the composite furnace roof from sliding.

[0028] As Figure 1 , 2 3, 5 shown, a hole structure 4 is provided inside the casting body I 1. The hole structure 4 penetrates through the upper and lower ends of the casting body I 1. The hole structure 4 includes a hole I 41, a hole II 42, and a hole III 43. The inside of the hole I 41 is a conical frustum structure, and the diameter continuously becomes smaller along the direction from the lower end to the upper end of the casting body I 1. When the casting body I 1 is placed above the flue wall, the area of the lower end of the hole I 41 is large, facilitating the flow of flue gas. The small area of the upper end is to prevent the situation that the temperature inside the flue wall decreases due to excessive flue gas flow. The inside of the hole II 42 is cylindrical and is inscribed with one end of the hole I 41. The inside of the hole III 43 is also cylindrical, and the diameter of the hole III 43 is larger than the diameter of the hole II 42. During roasting, a plate member can be placed to block the hole III 43 to prevent the loss of flue gas. The hole I 41, the hole II 42, and the hole III 43 are arranged in sequence from the lower end to the upper end of the casting body I 1, and the three are connected through. The hole structure 4 is to discharge the flue gas inside the flue wall, and at the same time, combustion-supporting gas can be introduced into the hole structure 4 to increase the combustion efficiency.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
