When a certain pulverized coal storage tank needs to be emptied, a pulverized coal storage tank discharging pipe 210 of the pulverized coal storage tank is connected with a feeding pipe 1100 of a pulping device; after the pulverized coal storage tank is emptied, the discharging pipe 210 of the pulverized coal storage tank and the feeding pipe 1100 of the slurrying device need to be separated in time and the slurrying device needs to be removed, so that the working site is more orderly. Therefore, it is necessary to frequently connect or separate the pulverized coal storage tank discharging pipe 210 and the feeding pipe 1100 of the slurrying device, and the connection or separation process needs to be simple and convenient.
When connecting the pulverized coal storage tank discharging pipe 210 with the feeding pipe 1100 of the slurrying device, the central axes of the pulverized coal storage tank discharging pipe 210 and the feeding pipe 1100 of the slurrying device are aligned first, wherein the diameter of the pulverized coal storage tank discharging pipe 210 may be equal to or smaller than the diameter of the feeding pipe 1100 of the slurrying device. Next, the discharge tube flange 220 is placed between the inflatable gasket 1500 and the feed tube 1100 of the slurrying device. Then, the gas is filled into the gas-filled sealing ring 1500 until the inner wall of the gas-filled sealing ring 1500 is connected with the pulverized coal storage tank discharging pipe 210 in a pressurized manner, and at this time, the pulverized coal storage tank discharging pipe 210 is connected with the feeding pipe 1100 of the slurrying device in a sealing manner.
When the discharging pipe 210 of the pulverized coal storage tank is separated from the feeding pipe 1100 of the pulping device, only the air-charging sealing ring 1500 needs to be deflated. When the inner diameter of the pneumatic sealing ring 1500 is larger than the outer diameter of the discharging pipe flange 220 of the pulverized coal storage tank discharging pipe 210, the pulverized coal storage tank discharging pipe 210 is separated from the feeding pipe 1100 of the slurry making device.
