Description

Technical Field

[0001] The utility model relates to the technical field of carbon processing, in particular to a flue combination brick for a carbon furnace. Background Art

[0002] Carbon is formed by removing combustible volatiles from coal through calcining at 1200-1300℃ without open flame. The calcination or refining of carbon is completed by a special carbon furnace. When the carbon furnace is actually used, a large amount of calcination flue gas will be generated. The flue is now mostly converted into a flue gas recovery channel to complete the exhaust of the calcination flue gas. In actual use, it has the advantages of stable structure, safe use and good effect.

[0003] The prior art discloses a carbon furnace flue gas waste heat recovery brick structure with publication number: CN218155488U, which includes a carbon furnace, a hollow brick, a sealing ring, a fixed plate, a limit plate, a connecting rod, a clamping groove, a clamping rod, an abutting spring, a first rack, a second rack, a limit ring, a gear, a handle, a sealing cover, an elastic sealing film, a cable tie and an alarm. The sealing rings on the two hollow bricks are brought into contact with each other, and at the same time, the connecting rod is passed through the limit plate, the first rack is inserted into the fixed plate, the second rack is inserted into the limit plate, and the gear is driven to rotate by turning the handle, so that the first rack is rotated. The first rack and the second rack are close to each other, thereby driving the limit plate to move toward the fixed plate, so that the connecting rod slides in the limit plate, so that the clamping rod clamps the clamping groove, thereby limiting the limit plate, so that the two hollow bricks are close to each other to achieve sealing, and the first rack and the second rack are taken out to adjust the limit plates on different hollow bricks; when the hollow brick is working, air leakage occurs, and gas enters the elastic sealing membrane, causing the elastic sealing membrane to expand. When the elastic sealing membrane abuts against the alarm, the alarm is triggered, which is convenient for maintenance personnel to quickly check and repair.

[0004] In the above-mentioned utility model, when connecting two hollow bricks, it is necessary to pre-insert the limiting plate through the connecting rod, but there is no alignment structure. It is difficult for the operator to complete the docking work of the connecting structure in one go. Performing the docking work multiple times will increase the operation steps and affect the installation efficiency. At the same time, the hollow bricks have a certain weight, and it is difficult for the operator to move and use them, which reduces the practicality of this utility model.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

The operator then wraps the tape around the side walls of the two adjacent groups of installation covers with his hands. Since the width of the tape is greater than the length of the gap between the two adjacent groups of installation covers, it is ensured that the tape can contact the two adjacent groups of installation covers. When the calcination flue gas moves out through the gap between the first hollow brick and the second hollow brick, it will enter between the two adjacent groups of installation covers. Since the calcination flue gas has a certain temperature, it can melt the tape. The operator can observe the state of the tape to find out whether there is a calcination flue gas leakage. By setting up the installation cover, the investment cost is reduced without affecting the prompt of calcination flue gas leakage, which provides a guarantee for the continuous use of the flue combination bricks for carbon furnaces.

[0035] Working principle:

[0036] Before actually using the first hollow brick 1 and the second hollow brick 2, the eight sets of threaded blind holes 7 and the eight sets of connecting screws 10 are used to cooperate with each other. The operator rotates the eight sets of connecting screws 10 clockwise and counterclockwise by hand. The eight sets of connecting screws 10 respectively drive the eight sets of tapered blocks 12 to move through the eight sets of connecting blocks 11. When the eight sets of tapered blocks 12 move to the appropriate position, the rotation of the eight sets of connecting screws 10 is stopped. At this time, the eight sets of balls 14 can be brought into contact with the ground. At this time, the first hollow brick 1 and the second hollow brick 2 can be moved. The eight sets of balls 14 roll inside the eight sets of ball sockets 13 respectively. Since the surface of the eight sets of balls 14 is smooth, the eight sets of balls 14 can be moved to the ground. The first hollow brick 1 and the second hollow brick 2 can be easily moved and used. When the first hollow brick 1 and the second hollow brick 2 need to be assembled, the operator moves the second hollow brick 2 by hand. When the four groups of tapered blocks 12 are respectively moved into the interior of the four groups of tapered grooves 8, the second hollow brick 2 is pushed. The four groups of tapered blocks 12 and the four groups of connecting blocks 11 will respectively enter the interior of the four groups of aligned blind holes 9 on the same side. At this time, the eight groups of threaded connecting holes 15 and the eight groups of threaded through holes 16 are used to cooperate with the threads of the eight groups of mounting bolts 17. The operator rotates the four groups of mounting bolts 17 clockwise by hand. When the four groups of mounting bolts 17 are moved into the same When the first hollow brick 1 and the second hollow brick 2 are assembled, the first hollow brick 1 and the second hollow brick 2 are assembled. The installation of the remaining brick bodies can be obtained by the same operation. The fixed sleeve 6 is provided, which can facilitate the docking of the two hollow bricks and the movement of the hollow bricks, thereby improving the practicality of the carbon furnace flue combination bricks. At the same time, according to the above operation, when the first hollow brick 1 and the second hollow brick 2 are assembled, a group of annular protrusions 3 will move into the inside of a group of annular grooves 4. The operator then manually wraps the tape 18 around the side walls of the two adjacent groups of mounting covers 5. Due to the tape The width of 18 is greater than the length of the gap between two adjacent groups of mounting covers 5, ensuring that the tape 18 can contact the two adjacent groups of mounting covers 5. When the calcination flue gas moves out through the gap between the first hollow brick 1 and the second hollow brick 2, it will enter between the two adjacent groups of mounting covers 5. Since the calcination flue gas has a certain temperature, the tape 18 can be melted. The operator can observe the state of the tape 18 to determine whether there is a calcination flue gas leakage. By setting up the mounting cover 5, the investment cost is reduced without affecting the prompt of calcination flue gas leakage, which provides a guarantee for the continued use of flue combination bricks for carbon furnaces.
