The connecting frame 2 part of this furnace frame is made of vermicular graphite cast iron material, while the fixed frame 1 part uses traditional gray cast iron. For the tamping coke oven furnace frame composed of the fixed frame 1 and the connecting frame 2, the fixed connection between the positioning frame 21 and the inner side wall of the fixed frame 1 and between the fitting frame 22 and the inner wall of the fixed frame 1 both enhance the overall structural strength of the furnace frame. And during use, the heat insulation ring 23 can play a certain heat insulation role to prevent heat from directly passing through the inside of the connecting frame 2 to the inside of the fixed frame 1. After the blocked heat is transferred to the position of the fitting frame 22, it will be more evenly distributed in the fitting frame 22 and transferred to the inside of the fixed frame 1 through surface contact, making the fixed frame 1 receive heat evenly.

[0017] The anti-disengagement device 3 includes a hanging plate 31, the inner wall of the hanging plate 31 is slidably connected with a hexagon screw 32, the outer wall of the hanging plate 31 is fixedly connected with a limiting block 33, the inner wall of the limiting block 33 is slidably connected with a screw rod 34, the outer wall of the bottom of the screw rod 34 is threadedly connected with an internal thread ring 35, the outer wall of the bottom of the internal thread ring 35 is rotatably connected with a support seat 36, the top of the screw rod 34 is fixedly connected with a blocking block 37, the outer wall of the blocking block 37 is fixedly connected with a limiting rod 38, the outer wall of the hexagon screw 32 is threadedly connected with the inner wall of the fixed frame 1, the outer wall of the support seat 36 is fixedly connected to the outer wall of the fixed frame 1, the outer wall of the screw rod 34 is slidably connected with the inner wall of the support seat 36, and the inner wall of the internal thread ring 35 is threadedly connected with the outer wall of the screw rod 34.

[0018] The hanging plate 31 includes a fixing plate 311. A positioning hole 312 is formed in the wall of the fixing plate 311. An outer wall at the top of the fixing plate 311 is fixedly connected with a connecting block 313. The outer wall of the connecting block 313 is in contact with the outer wall of a blocking block 37 through an insertion groove 314, and the insertion groove 314 is formed in the wall of the connecting block 313. The inner wall of the connecting block 313 is slidably connected with the outer surface of a limiting rod 38 through a through hole 315, and the through hole 315 is formed in the wall of the connecting block 313. The outer wall of a hexagonal screw 32 is slidably connected with the inner wall of the fixing plate 311 through the positioning hole 312. The outer wall of the fixing plate 311 is fixedly connected with the outer wall of a fixing frame 1 through the hexagonal screw 32. The hanging plate 31 is fixedly connected with the outer wall of the fixing frame 1 by passing the hexagonal screw 32 through the positioning hole 312 to ensure the firmness of the connection. When it is necessary to prevent the furnace frame from separating from other components, rotate the internal thread ring 35 on the support seat 36. Through threaded drive, the screw rod 34 rises from the bottom under the positioning of the limiting block 33, and then pushes the blocking block 37 to move upward until the blocking block 37 enters the insertion groove 314 of the connecting block 313 and contacts the surface of the insertion groove 314. At this time, the blocking block 37 and the groove of the fixing plate 311 complete the clamping of other components.

[0019] Working principle:

[0020] During use, the connecting frame 2 part of this furnace frame is made of vermicular graphite cast iron, which has the advantages of high strength, good toughness, excellent heat resistance, good thermal conductivity and good casting performance. It can withstand various mechanical stresses and thermal stresses generated during the coking process of the stamping coke oven, ensuring the stability and safety of the furnace frame structure, and at the same time extending the service life of the furnace frame. The fixing frame 1 part uses traditional gray cast iron, reducing the cost of the overall structure. For the stamping coke oven furnace frame composed of the fixing frame 1 and the connecting frame 2, the positioning frame 21 is fixedly connected with the inner side wall of the fixing frame 1, and the fitting frame 22 is fixedly connected with the inner wall of the fixing frame 1, both of which enhance the overall structural strength of the furnace frame. During use, the heat insulation ring 23 can play a certain heat insulation role, avoiding heat from directly passing through the inside of the connecting frame 2 to the inside of the fixing frame 1. After the blocked heat is transferred to the position of the fitting frame 22, it will be more evenly distributed in the fitting frame 22 and transferred to the inside of the fixing frame 1 through surface contact, making the fixing frame 1 evenly heated, thereby reducing the thermal stress and deformation risk of the furnace frame caused by high temperature.

[0021] The anti - detachment device 3 is provided to make it difficult for the hanging plate 31 to fall off. The hanging plate 31 is fixedly connected to the outer wall of the fixed frame 1 through a hexagonal screw 32 passing through the positioning hole 312 to ensure the firmness of the connection. When it is necessary to prevent the furnace frame from detaching from other components, rotate the internal - thread ring 35 on the support seat 36. The threaded drive causes the screw rod 34 to rise from the bottom under the positioning of the limit block 33, and then pushes the blocking block 37 to move upward until the blocking block 37 enters the insertion groove 314 of the connecting block 313 and contacts the surface of the insertion groove 314. At this time, the blocking block 37 and the groove of the fixing plate 311 complete the clamping of other components. During movement, the blocking block 37 at the top of the screw rod 34 cooperates with the connecting block 313 on the fixing plate 311 through the limit rod 38. The limit rod 38 slides stably in the through - hole 315, thereby ensuring the stable operation of the screw rod 34. The anti - detachment device 3 plays a role in preventing the hanging plate 31 from accidentally detaching. Each component in the anti - detachment device 3 cooperates closely to ensure the safety and stability of the furnace frame during use.
