Technical Field

[0001] The utility model relates to the technical field of slag coolers, and particularly relates to a sealing device for a slag cooler for preventing slag leakage. Background Technique

[0002] A slag cooler, also known as a slag cooler, mainly consists of a cylinder body, a slag inlet box, a slag outlet box, a power transmission device, a chassis and an electrical control system. The cylinder body and the partition frame both adopt a water-cooled wall structure, and slag guiding sheets are welded on the inner wall of the cylinder body and the partition frame.

[0003] At present, when the drum-type slag cooler used in power plants is operating, there will be phenomena of ash leakage and slag leakage. At present, the effect of preventing slag and ash leakage of the drum-type slag cooler is poor, and during the use process, ash and slag will leak through the gap between the fixed barrel of the slag cooler and the sealing cover. Since the temperature of the ash and slag is very high, it poses a great harm to the equipment and operators. For this reason, a sealing device for a slag cooler for preventing slag leakage is proposed. Content of the Utility Model

[0029] As Figures 1 to 6 shown, a slag leakage prevention sealing device for a slag cooler includes: a fixed barrel 1, with a plurality of support members 101 provided on the outside of the fixed barrel 1, and a fixed pipe 104 provided at the feeding end of the fixed barrel 1; a sealing mechanism, arranged outside the connecting pipe 103 and used to block ash slag. The sealing mechanism includes a sealing component 2 and a connecting component 3. The connecting component 3 includes a fixing member and a blocking member. The fixing member is arranged outside the fixed pipe 104, the blocking member is arranged inside the fixing member, and the sealing component 2 is arranged outside the fixing member. Moreover, the fixing member, the sealing component 2, and the blocking member guide the flowing direction of the ash slag inside the fixed barrel 1. Specifically, when cooling the furnace slag, first, the fixed barrel 1 reduces the temperature of the furnace slag. During the temperature reduction process, through the cooperation of the fixing member, the blocking member, and the sealing component 2, the ash slag inside the fixed barrel 1 is blocked, avoiding the ash slag escaping outward through the gap between the fixing member and the fixed pipe 104 during the cooling process of the furnace slag. The fixed barrel 1 can reduce the temperature of the furnace slag during use. The fixed barrel 1 is a prior art and will not be explained in detail here.

[0030] As Figures 1 to 6 shown, an air outlet ring 105 is further provided inside the fixed pipe 104. The inside of the air outlet ring 105 is hollow. A plurality of through holes 106 are opened inside the fixed pipe 104. The axis line of the through holes 106 is perpendicular to the axis line of the fixed pipe 104, and the through holes 106 are communicated with the air outlet ring 105. Specifically, the inner wall of the air outlet ring 105 is provided with inclined air outlet grooves, and the openings of the air outlet grooves face the furnace slag outlet end of the fixed barrel 1. The through holes 106 can introduce air into the inside of the air outlet ring 105, and the air entering the inside of the air outlet ring 105 flows out through the air outlet grooves. The air blown out by the air outlet grooves can form an air curtain, thereby blocking the ash slag inside the fixed barrel 1 and avoiding the ash slag escaping outward through the gap between the fixing member and the fixed pipe 104 during use.

[0031] As Figures 1 to 6As shown in the figure, the fixing member includes a sealing cover 301. The sealing cover 301 is sleeved outside the fixing pipe 104. An installation ring 308 is provided outside the sealing cover 301. A plurality of connecting clips 306 are provided on the side of the installation ring 308 relative to the fixed barrel 1. A connecting ring 307 is provided between the installation ring 308 and the connecting clip 306. The connecting ring 307 is connected to the fixed barrel 1, and the connecting ring 307 rotates relative to the sealing cover 301. An air inlet pipe 302, a connecting pipe 103 and an air pump 102 are sequentially provided outside the sealing cover 301, and the air pump 102 is connected to the support member 101. Specifically, the connecting clip 306 cooperates with the installation ring 308 to connect the sealing cover 301 and the connecting ring 307. The contact surface between the connecting clip 306 and the connecting ring 307 is arc-shaped, so that the connecting clip 306 can closely fit with the connecting ring 307 during rotation, ensuring the stability of the sealing cover 301 relative to the fixing pipe 104 during rotation. There is a gap between the fixing pipe 104 and the sealing cover 301, so as to guide air during use. The air pump 102 can increase the air pressure, so that the air pressure inside the sealing cover 301 is lower than the air pressure inside the fixed barrel 1. The air pump 102 is a prior art and will not be explained in detail here. The connecting pipe 103 connects the air inlet pipe 302 and the air pump 102 to conduct air.

[0032] As Figures 1 to 6 shown in the figure, the sealing assembly 2 includes a fixing cover 202. The fixing cover 202 is arranged at one end of the sealing cover 301. A feed pipe 201 is provided inside the fixing cover 202, and the feed pipe 201 is communicated with the fixed barrel 1. A fixing ring 203 is provided on the side of the fixing cover 202 relative to the sealing cover 301, and the diameter of the fixing ring 203 is smaller than the diameter of the fixing pipe 104. Specifically, the fixing cover 202 seals the end of the sealing cover 301 and fixes the position of the feed pipe 201 at the same time, ensuring the stability during the ash slag cooling process. The fixing cover 202 and the sealing cover 301 are connected by bolts or buckles, which is convenient for quick disassembly and installation during use.

[0033] As Figures 1 to 6As shown, the barrier member includes a first deflector 303, a second deflector 304, a diverter plate 305, and a sealing ring 309. The sealing ring 309 is disposed inside the sealing cover 301, and the inner wall of the sealing ring 309 abuts against the fixed pipe 104. The first deflector 303 and the diverter plate 305 are connected to the sealing cover 301, and the diverter plate 305 is disposed between the first deflector 303 and the sealing ring 309. The second deflector 304 is connected to the fixed pipe 104, and the first deflector 303, the second deflector 304, and the diverter plate 305 are all annular. Specifically, the sealing ring 309 is provided with a sealing strip on the side opposite to the fixed pipe 104, so as to seal the air flowing inside the sealing cover 301 during use and prevent air leakage during use. The diverter plate 305 distributes the air entering from the intake pipe 302, so that the air can be evenly distributed on both sides of the diverter plate 305. The first deflector 303, the second deflector 304, and the fixed ring 203 guide the air entering the inside of the sealing cover 301, so that the air can flow into the fixed barrel 1. The cooperation of the first deflector 303 and the second deflector 304 guides the air and blocks the ash at the same time, preventing the ash from blocking the intake pipe 302 during use.

[0034] As Figures 1 to 6 shown, a flow guiding ring 204 and a blocking ring 205 are further provided between the fixed ring 203 and the fixed pipe 104. The flow guiding ring 204 is connected to the fixed pipe 104, and the blocking ring 205 is connected to the fixed ring 203. Specifically, during use, the air flowing out along the first deflector 303 and the second deflector 304 is discharged through the gap between the flow guiding ring 204 and the blocking ring 205. The flow guiding ring 204 cooperates with the blocking ring 205 to further block the ash inside the fixed barrel 1, preventing the ash from entering the inside of the sealing cover 301 and causing blockage.
