Furthermore, a safety valve 13 is arranged at the top of the mud tank 1, and the safety valve 13 is used for automatically opening the valve for pressure relief when the pressure in the mud tank 1 reaches a set value.
Further, a bypass pipe 3 is arranged at the bottom end of the discharge pipe 2, a vent valve is arranged on the bypass pipe 3, and the bypass pipe 3 is used for evacuating mud slurry in the mud tank 1.
The structure of the second embodiment is basically the same as that of the first embodiment, except that the grouting machine is modified by a slurry spraying machine, a slurry spraying pipe 14 is arranged at the top of the slurry tank 1, the middle part of the slurry spraying pipe 14 is communicated with the air inlet pipe 10, one end of the slurry spraying pipe 14 is connected to a compressed air source, the other end of the slurry spraying pipe is communicated with the discharge pipe 2 and is commonly connected with a rubber hose, the end part of the rubber hose is connected to a cleaning hole of the vertical brick coal air flue 6, and a slurry spraying valve 15 is arranged at one end, close to the rubber hose, of the slurry spraying pipe 14.
The concrete operation method for repairing leakage of the vertical brick coal gas flue 6 of the coke oven by adopting the embodiment is as follows: 1. selecting an upright brick coal gas passage 6 to be grouted, and closing a coal gas valve of the number; 2. the vertical pipe cleaning hole cover of the vertical brick coal gas passage 6 to be grouted is disassembled, and the vertical brick coal gas passage 6 is penetrated by a threaded steel bar with the diameter of 14-16 mm; 3. the nozzle cleaning hole cover is disassembled, the gas nozzle 7 is taken out, the gas nozzle plug 8 is plugged in from the cleaning hole, the plug 82 position plugs the connecting position of the vertical pipe, and slurry is prevented from overflowing from the nozzle; 4. Connecting the head of the rubber hose with the cleaning hole of the vertical pipe; 5. closing a slurry spraying valve 15 of the slurry spraying machine with the slurry, and fully opening a grouting valve 4; for safety, a person can observe the condition of a vertical channel nozzle of a guniting outlet at the furnace top, and interphone communication is adopted; 6. the operator gradually opens the air inlet valve by one hand and gradually closes the air outlet valve by the other hand, simultaneously observes the change of the pressure gauge 12, presses mud into the discharge pipe 2 from the mud tank 1 by pressure, and fills the vertical brick coal gas channel 6 for leak repairing; 7. when the pressure reaches a control value, the grouting valve 4 is closed, an operator closes the air inlet valve by one hand and opens the air outlet valve by the other hand, the grouting valve 4 is opened when the slurry stays in the vertical brick coal air flue 6 for 60 seconds, and the slurry flows back into the slurry tank 1 under the action of gravity; 8. disconnecting the special connecting pipe head at the outlet of the rubber tube of the guniting machine from the cleaning hole of the vertical tube; a vertical brick coal gas passage 6 which is sprayed by a screw steel bar with the diameter of 14-16 mm; 9. taking out a plug for plugging the nozzle, cleaning the nozzle pipe, installing the gas nozzle 7, and reinstalling a nozzle cleaning hole cover and a riser cleaning hole cover; and finally, opening the gas valve of the number to resume normal operation.
