In the embodiment, in the process of loading coal in a top-loading tamping integrated coke oven, a U-shaped guide sleeve lifting device 6 is utilized to drop an n-1 type U-shaped sealing guide sleeve 7, and an n-th hole carbonization chamber 11 is communicated with an n-1 hole carbonization chamber 10; and simultaneously, the n+2-th U-shaped sealing guide sleeve 12 is fallen by utilizing the U-shaped guide sleeve lifting device 6, and the n-th hole carbonization chamber 11 is communicated with the n+2-th hole carbonization chamber 13.
The n-1 type U-shaped sealing guide sleeve 7 and the n+2 type U-shaped sealing guide sleeve 12 form a group of double U-shaped sealing guide sleeves. As shown in fig. 2, the direction from left to right is the coke oven side to the coke side, and 4 coal charging holes are arranged at the top of the nth hole carbonization chamber 11. In the coal charging and smoke guiding process, a first coal charging hole of the machine side number corresponding to an nth hole carbonization chamber 11 is communicated with a first coal charging hole of the machine side number corresponding to an n+2th hole carbonization chamber 13, a second coal charging hole of the nth hole carbonization chamber 11 is communicated with a second coal charging hole of the machine side number corresponding to an n-1th hole carbonization chamber 10, a third coal charging hole of the machine side number corresponding to the nth hole carbonization chamber 11 is communicated with a third coal charging hole of the machine side number corresponding to the n+2th hole carbonization chamber 13, and a fourth coal charging hole of the machine side number corresponding to the nth hole carbonization chamber 11 is communicated with a fourth coal charging hole of the machine side number corresponding to the n-1th hole carbonization chamber 10; namely, 2 groups of double U-shaped sealing guide sleeves are arranged on the vehicle body 1 for top loading coal and smoke guiding.
The lower coal pipe 3 is nested inside the double U-shaped sealing guide sleeve to realize top loading coal, and the lower coal pipe 3 is fixed below the coal bucket 2 and does not move along with the double U-shaped sealing guide sleeve; the U-shaped guide sleeve lifting device 6 is used for lifting and dropping the double U-shaped sealing guide sleeve. The flat gate 3 is communicated and cut off between the coal hopper 2 and the lower coal pipe 4 through the linear driving device 5, and the coal charging hole cover opening and closing device 9 is used for controlling movement of the coal charging hole cover 8 during coal charging and smoke guiding.
When the nth hole carbonization chamber 11 is ready for top loading coal, after receiving coal from a coal tower, the vehicle body 1 moves to a position where the lower coal pipe 4 is opposite to the nth hole carbonization chamber 11, and the 4 coal charging hole covers 8 of the nth hole carbonization chamber 11 to be charged with coal, the 2 coal charging hole covers 8 of the (n+2) th hole carbonization chamber 13 to be introduced with smoke dust and the 2 coal charging hole covers 8 corresponding to the (n-1) th hole carbonization chamber 13 to be introduced with smoke dust are respectively moved away by the coal charging hole cover opening and closing device 9. 2 groups of double U-shaped sealing guide sleeves are fallen through the U-shaped guide sleeve lifting device 6, and are tightly sealed with the coal charging hole seats 14 of the carbonization chambers through spherical sealing interfaces, so that coal charging smoke dust is prevented from overflowing.
