[0019] like Figure 1 As shown, a coke oven column fixing structure comprises a column 1, wherein a plurality of columns 1 are provided, and a reinforcement channel steel 3 is provided on the plurality of columns 1;
[0020] like Figure 1 and Figure 2 As shown, when implemented, it includes: a plurality of adjustment structures 2, which are respectively arranged on the reinforcement channel steel 3, each adjustment structure 2 includes a screw rod 21 inserted on the reinforcement channel steel 3, and an inner nut 22 and an outer nut 23 threadedly connected to the screw rod 21 and located on both sides of the reinforcement channel steel 3, and the end of each screw rod 21 is correspondingly arranged on each furnace column 1;
[0021] In this embodiment, the specifications of each furnace column 1 are the same, wherein each furnace column 1 is provided with a plurality of mounting holes 11 with the same spacing, which are vertically distributed, and each mounting hole 11 has the same specifications. The mounting holes 11 are used to install the reinforcement channel steel 3 at different positions of the furnace body, and are suitable for installation and use of different furnace bodies; the inner wall of each mounting hole 11 is provided with an internal thread, and the end of each screw 21 is threadedly connected to the mounting hole 11, so as to realize the disassembly and assembly of each screw 21;
[0022] In this embodiment, the reinforcing channel steel 3 is provided with a through hole 31 for installing each screw rod 21. During installation, each screw rod 21 is inserted through the corresponding through hole 31;
[0023] In this embodiment, each adjustment structure 2 is located on the same horizontal line, the reinforcing channel steel 3 and each furnace column 1 are cross-shaped, and the load on the furnace column 1 can be adjusted by the inner nut 22 and the outer nut 23.
[0024] like Figure 1 to Figure 2 As shown, in this embodiment, it is also necessary to explain that the dimensions of each component in the application document are selected and installed according to the actual needs on site. In addition, it should be noted that this application document only improves the shortcomings of the existing coke oven column during the heating and cooling process, the temperature change of the removed combustion chamber furnace body is greater than the temperature change of the adjacent retained combustion chamber, the furnace body shrinks or expands greatly, the furnace column and the furnace body are welded together and cannot be adjusted separately, affecting the free expansion of the combustion chamber masonry, causing the furnace wall deformation and the furnace body extrusion damage, etc., and does not involve other aspects; the working principle of the coke oven column fixing structure is introduced as follows:
[0025] During installation, first install the end of the screw rod 21 in the installation hole 11, then let the screw rod 21 pass through the through hole 31 of the reinforcement channel steel 3, and screw the inner nut 22 and the outer nut 23 on both sides of the waist of the reinforcement channel steel 3 to achieve the overall fixation of the furnace column 1 and the upper part of the reinforcement channel steel 3.
[0026] After the overall fixation, when the coke oven combustion chamber is cooled down and dismantled, when the tonnage of the tension rods of the furnace columns 1 fixed together is adjusted to be normal, the inner spring of the middle furnace column 1 is released and the outer spring is tightened, so that part of the load on the furnace columns 1 on both sides is shared to the middle furnace column 1, increasing the compression of the furnace body and preventing the furnace body from loosening; when the combustion chamber masonry is dismantled to the heating period, the inner nuts 22 and outer nuts 23 of the middle furnace column 1 and the furnace columns 1 on both sides are maintained at the same displacement.
[0027] When the combustion chamber is heated up, if the tonnage of the springs fixing the furnace columns 1 together is adjusted to be 1 t less than the normal load, the total load of the furnace columns 1 fixed together can be distributed by adjusting the inner nut 22 and the outer nut 23. When the tonnage needs to be increased, the inner nut 22 is loosened and the outer nut 23 is tightened; on the contrary, if the tonnage needs to be loosened, the inner nut 22 is appropriately tightened and the outer nut 23 is loosened to adjust the load of a single furnace column 1 under the total load, keep the load of the furnace column 1 slightly lower than the normal pressure, and adjust it every two hours until the heating is completed, so as to meet the personalized load requirements of each furnace column 1. After the combustion chamber is repaired, the inner nut 22, the outer nut 23, the reinforcing channel steel 3, and the screw 21 are removed to restore the normal tonnage of the pull rod.
[0028] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
