Detailed ways

The specific embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings and through the description of the preferred embodiments.

A furnace mouth insulation door for coke oven repair, the coke oven structure includes a coke oven carbonization chamber machine and a coke oven mouth, and a furnace mouth insulation door is provided in the furnace mouth when the coke oven carbonization chamber is repaired; The thermal insulation door includes a frame 1, the frame 1 includes two longitudinal beams 101, and the two longitudinal beams 101 are longitudinally spaced apart; two ends of the two longitudinal beams 101 are respectively connected by a beam 102; the frame 1 is an integral structure ; A plurality of reinforcing ribs 103 for supporting are arranged between the two longitudinal beams 101; the side of the frame 1 is connected with a ceramic fiber blanket 2; Two beams 102 form a rectangular frame structure, which plays a main supporting role. A ceramic fiber blanket 2 is arranged on the side of the frame 1. The ceramic fiber blanket 2 plays a role of heat insulation, and the ceramic fiber blanket 2 and the frame 1 form a door panel. Structure, through the setting of such a structure, the structure of the traditional stainless steel iron door is changed, and the setting of the ceramic fiber blanket 2 can play a major role in heat insulation and reduce the loss of the internal temperature of the coke oven machine from the furnace mouth; The arrangement of the reinforcing ribs 103 can prevent the frame 1 from being deformed and the ceramic fiber blanket 2 can be fixedly installed.
