The slag containing barrel 17 consists of a bottom plate 19, three enclosing plates 20 and a sliding plate 18, the enclosing plate 20 adjacent to the sliding plate 18 is connected with a third connecting rod 15, the lower end of the enclosing plate 20 is connected with the upper end edge of the bottom plate 19, the sliding plate 18 is in sliding connection with the enclosing plates 20, the two sides of the sliding plate 18 are provided with limiting bulges 21, the edge of the enclosing plate 20 is provided with a limiting sliding groove 22 matched with the limiting bulges 21, the limiting bulges 21 are in sliding connection with the groove bottom of the limiting sliding groove 22, and the limiting bulges 21 and the limiting sliding groove 22 are convenient for the sliding plate 18 to stably slide and prevent the sliding plate 18 from separating from the enclosing plates 20; the bottom plate 19 and the horizontal plane form an included angle of 30 degrees, the sliding plate 18 and the horizontal plane form an included angle of 80 degrees, and the sliding plate 18 is arranged above the lower end of the bottom plate 19.

The opening device is arranged at one side of the falling of the slag containing barrel 17, the opening device consists of a push rod 23, two sliding barrels 25, a spring 24 and a roll shaft 26, two ends of the roll shaft 26 are respectively and rotatably connected with the end parts of the two sliding barrels 25, the push rod 23 is connected with a vertical mounting rod of the mounting base 1, the inner side wall of the sliding barrel 25 is in sliding connection with the side wall of the push rod, two ends of the spring 24 are respectively connected with the inner barrel bottom of the sliding barrel 25 and the push rod 23, the opening device is arranged at one side of the slag containing barrel, when the slag containing barrel 17 falls, the sliding plate 18 is contacted with the roll surface of the roll shaft 26, the coaming 20 and the bottom plate 19 continue to descend, the sliding plate 18 is not moved, the slag in the slag containing barrel 17 slides down along the bottom plate 19, when the limit protrusion 21 slides to the upper end of the limit chute 22, the spring 24 is compressed, the slide plate 18 moves down, the roller shaft 26 rolls, when the slide 18 is separated from the roller shaft 26, the lower end of the slide 18 is again in contact with the bottom plate 19, opening the device to facilitate the dumping of the slag.

The working mode of the invention is as follows: boiler slag materials are loaded into the slag containing barrel 17 at the ascending end of the slag containing barrel 17, after slag is loaded, the driving device drives the rotating device to rotate through the connecting device, the rotating device can convey the slag materials to a high place to be discharged, the opening device is arranged at one side of the falling of the slag containing barrel 17, when the slag containing barrel 17 falls, the sliding plate 18 is in contact with the roller surface of the roller shaft 26, the enclosing plate 20 and the bottom plate 19 continue to fall, the sliding plate 18 is not moved, the slag materials in the slag containing barrel 17 slide down along the bottom plate 19, when the limiting bulge 21 slides to the upper end of the limiting sliding chute 22, the spring 24 is compressed, the sliding plate 18 moves downwards, the roller shaft 26 rolls, when the sliding plate 18 is separated from the roller shaft 26, the lower end of the sliding plate 18 is in contact with the bottom plate 19 again, and the opening device is convenient for dumping the slag materials; the negative pressure of the boiler furnace outlet and the running oxygen amount of the boiler are controlled, so that the power consumption of equipment can be reduced, and the production cost is reduced; arrange the residue device and be convenient for splendid attire and the residue in the transportation boiler, and dress sediment bucket 17 evenly sets up along second chain 8, when having dress sediment bucket 17 to rise, has dress sediment bucket 17 to descend, guarantees that motor 3 only does work to the transportation of residue, reduces the power consumption of motor 3.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
