DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 The high-strength coke oven column shown comprises a column body 1 and fixing plates 2 installed at the front and rear ends of the column body 1;

[0022] The front end outer wall of the fixed plate 2 and the left and right end outer walls of the furnace column body 1 are provided with a heat-resistant coating 5. When the steel material required for the spring is heated, the steel material is moved to the inside of the coke oven. The furnace column body 1 supports the height of the inside of the coke oven and limits the position of the internal combustion material, so that the steel material can be heated evenly during heating.

[0023] An anti-deformation column 12 is fixedly connected inside the furnace column main body 1, and a positioning column 11 is fixedly connected inside the anti-deformation column 12 to limit the bending amplitude of the furnace column main body 1. When the furnace column main body 1 is used in a high-temperature environment inside a coking oven, the high-temperature resistant positioning column 11 can limit the bending amplitude of the furnace column main body 1, and the anti-deformation column 12 can limit the position of the furnace column main body 1.

[0024] like Figure 2 As shown, the upper and lower outer walls of the anti-deformation column 12 are fixedly connected with the top plate 13, a reserved groove 15 is opened inside the furnace column body 1, and the left and right outer walls of the positioning column 11 are fixedly connected with the connecting blocks b10 that penetrate the inside of the anti-deformation column 12, and a connecting block a9 is fixedly connected between the connecting block b10 and the furnace column body 1 to limit the position of the positioning column 11 inside the furnace column body 1.

[0025] During the use of the positioning column 11, the top plate 13 and the reserved groove 15 are fixedly connected by welding, and the position of the positioning column 11 is limited. The reserved groove 15 is opened for welding and installation of the positioning column 11 and other components. When the furnace column body 1 is deformed, the connecting block a9 and the connecting block b10 can limit the amplitude of the furnace column body 1 when it is thermally expanded and bent. By fixing it with welding, it is avoided that the connecting block a9 and the connecting block b10 are pulled to move during the deformation of the furnace column body 1.

[0026] like Figure 2 As shown, the positioning column 11 is made of silicon carbide material, and the anti-deformation column 12 is made of zirconium oxide material.

[0027] The positioning column 11 and the anti-deformation column 12 are more resistant to high temperatures, thereby preventing themselves from bending when in a high temperature environment for a long time.

[0028] like Figure 1 As shown, two fixing plates 2 are provided, and a plurality of reinforcing ribs b14 are equidistantly fixedly connected between the two fixing plates 2 to limit the fixing plates 2 from curling inwards. The outer walls at both ends of the fixing plates 2 are fixedly connected with connecting plates a3, and the front end outer walls of the plurality of connecting plates a3 are respectively provided with front-to-back through-mounting holes a4 near the upper and lower sides so as to be fixedly installed between the inner walls at the front and rear ends of the coking oven by means of external fixing screws.

[0029] During the use of the furnace column body 1, the reinforcing rib b14 is used to prevent the fixing plate 2 from thermal expansion and deformation in a high temperature environment. When the furnace column body 1 and the inside of the coke oven are fixedly connected, the connecting plate a3 is fitted into the positioning hole inside the coke oven through the external fixing screws, and the fixing screws are respectively passed through the installation hole a4 and the positioning hole and tightened to fix them.

[0030] like Figure 1 As shown, the upper outer walls of the two fixed plates 2 are fixedly connected with connecting plates b6, and the upper outer walls of the multiple connecting plates b6 are provided with vertical through-mounting holes b7 near the left and right sides respectively so as to be fixedly connected with the upper and lower inner walls of the coke oven through external fixing screws, and the front end outer wall of the fixed plate 2 is equidistantly provided with multiple reinforcing ribs a8 to increase the stress on the surface of the fixed plate 2, and the two fixed plates 2 are fixedly connected with the connecting plates a3 and b6 by welding.

[0031] When the furnace column body 1 is fixedly connected to the inside of the coke oven, the connecting plate b6 is fitted with the positioning holes on the inner walls of the upper and lower ends of the coke oven through external fixing screws, and the fixing screws are respectively passed through the installation holes b7 and the positioning holes and tightened to fix them.

[0032] The implementation principle of this embodiment is: when the furnace column main body 1 supports the internal structure of the coke oven, after being fixedly connected to the internal structure of the coke oven through the connecting plates a3 and b6, the furnace column main body 1 can support the internal height of the coke oven and limit the position of the combustion materials inside the coke oven during use. During the heating process, the positioning columns 11 and the anti-deformation columns 12 can prevent the furnace column main body 1 from bending during use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
