[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The carbon roasting furnace insulation transverse wall structure of this utility model involves placing a first precast brick, a second precast brick, a third precast brick, and a fourth precast brick around the exhaust precast brick during the installation of the exhaust vent above the transverse wall. The exhaust precast brick is located in a set of open slots. The placement operation is then performed using an installation mechanism.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 7As shown, the present invention discloses a heat-insulating transverse wall structure for a carbon roasting furnace, comprising a first precast brick 1, a second precast brick 11, a third precast brick 12, a fourth precast brick 13, and a flue gas precast brick 14. The first precast brick 1, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13 are all rectangular, and each of them has an opening groove 16 at one corner, forming a set of square opening grooves 16. The flue gas precast brick 14 is square in plan view. A circular groove 17 is formed in the center of the flue gas precast brick 14. The flue gas precast brick 14 is located within a set of opening grooves 16, and is installed within the opening grooves 16 via an installation mechanism. A refractory mechanism is provided between the flue gas precast brick 14 and the opening grooves 16. An opening ring 15 is fixedly connected to the opening of the circular groove 17. In the prior art, at the smoke exhaust position above the transverse wall, the smoke exhaust generates a large amount of heat, which easily causes cracks at the edges of the existing smoke exhaust bricks, affecting the working state of the entire transverse wall and causing errors in the internal firing quality. Therefore, in actual operation, when installing the smoke exhaust position above the transverse wall, a first precast brick, a second precast brick 11, a third precast brick 12, and a fourth precast brick 13 are placed around the smoke exhaust precast brick 14, which is located in a set of opening grooves 16. Then, the placement operation is carried out by the installation mechanism. After placement, the refractory mechanism is used to fill the gaps between the opening grooves 16 of the first precast brick, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13 and the smoke exhaust precast brick 14 to complete the refractory operation.

[0026] The installation mechanism includes an arc-shaped groove 2; a pair of symmetrically distributed arc-shaped grooves 2 are provided on each of the four side walls of the smoke exhaust precast brick 14; semi-circular blocks 21 are fixed to each of the two side walls of the opening groove 16; the semi-circular blocks 21 and the arc-shaped grooves 2 have the same center; the first precast brick 1 and the second precast brick 11 are installed with the third precast brick 12 and the fourth precast brick 13 through a bayonet unit;

[0027] The bayonet unit includes a bayonet block 24 and a bayonet slot 25; the first precast brick 1, the second precast brick 11, the third precast brick 12 and the fourth precast brick 13 are fixed to one side wall with the bayonet block 24, and the bayonet slot 25 is opened on the other side wall; the top view of the bayonet block 24 and the bayonet slot 25 are both T-shaped.

[0028] During operation, a semi-circular block 21 is placed into an arc-shaped groove 2, forming a arrangement of the first precast brick 1, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13 surrounding the flue gas refractory brick. Since the semi-circular block 21 and the arc-shaped groove 2 have the same center, after the semi-circular block 21 is attached to the arc-shaped groove 2, a certain gap space is formed between the first precast brick 1, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13 and the flue gas refractory brick. Then, the heat resistance operation is completed through the refractory casting operation. When the flue gas precast brick 14 is venting smoke, the heat is restricted by the gap space and the refractory mechanism, reducing heat conduction. At the same time, the certain gap space avoids cracking caused by heat and lack of gaps.

[0029] The refractory structure includes a refractory mud layer 22; a refractory cloth layer 23 is fixedly attached to the inner wall of the opening groove 16; a refractory cloth layer 23 is fixedly attached to all four side walls of the flue gas precast brick 14; a refractory mud layer 22 is poured between the refractory cloth layer 23 of the opening groove 16 and the refractory cloth layer 23 of the flue gas precast brick 14; during operation, after the first precast brick 1, the second precast brick 11, the third precast brick 12 and the fourth precast brick 13 are installed on the flue gas precast brick 14, the refractory mud layer 22 is poured into the gap space to complete the heat insulation operation. The refractory mud layer 22 is made of high-alumina bauxite powder or corundum powder to provide a high-temperature resistant skeleton structure, and calcined clay or kaolin powder to enhance plasticity and adhesion; silicon carbide particles or zirconium oxide micro powder are used to improve thermal shock resistance and avoid the poor heat insulation and cracking caused by the brick bonding operation in the prior art.

[0030] The top of each of the first precast brick 1, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13 is provided with a pair of symmetrically distributed hand-held grooves 26; during operation, the hand-held grooves 26 can be used to facilitate the placement of the first precast brick 1, the second precast brick 11, the third precast brick 12, and the fourth precast brick 13.

[0031] The precast smoke exhaust brick 14 has an annular groove 33 at its top, and the annular groove 33 surrounds the opening ring 15; a cover post 31 is provided in the circular groove 17, and a cover plate 3 is fixedly connected to the top of the cover post 31; a cover ring 32 is fixedly connected to the bottom of the cover plate 3, and the cover ring 32 and the annular groove 33 are positioned corresponding to each other; a hand-held ring 34 is hinged to the top of the cover plate 3; during operation, the cover plate 3 can cover the circular groove 17 of the cover post 31, which can complete the coverage. At the same time, due to the arrangement of the cover post 31, the annular groove 33 and the cover ring 32, a double seal is completed to ensure the smoke exhaust sealing effect.

[0032] Working principle: When installing the smoke exhaust system above the transverse wall, precast bricks 11, 12, and 13 are placed around the smoke exhaust precast brick 14. The smoke exhaust precast brick 14 is located within a set of open slots 16. The installation mechanism is then used for placement. After placement, a refractory mechanism is used to fill the gaps between the open slots 16 and the smoke exhaust precast brick 14, completing the refractory operation. A semi-circular block 21 is then placed into an arc-shaped groove 2, forming a arrangement of the first, second, and third precast bricks 12 and 13 surrounding the smoke exhaust refractory brick. Because the semi-circular block 21 and the arc-shaped groove 2 have the same center, after the semi-circular block 21 is fitted into the arc-shaped groove 2, the first, second, and third precast bricks 12, 13, and 13... A certain gap space is formed between the fourth precast brick 13 and the flue gas refractory brick. Then, the heat resistance operation is completed through the refractory casting operation. When the flue gas precast brick 14 is venting smoke, the heat is restricted by the gap space and the refractory structure, reducing heat conduction. At the same time, the certain gap space avoids cracking caused by heat and lack of gap. After the first precast brick 1, the second precast brick 11, the third precast brick 12 and the fourth precast brick 13 are installed on the flue gas precast brick 14, the refractory mud layer 22 is poured into the formed gap space to complete the heat insulation operation. The refractory mud layer 22 is made of high alumina bauxite powder or corundum powder to provide a high-temperature resistant skeleton structure, calcined clay or kaolin powder to enhance plasticity and adhesion, and silicon carbide particles or zirconium oxide micro powder to improve thermal shock resistance. This avoids the poor heat insulation and cracking caused by the brick bonding operation in the prior art.
