Rotating drum sealing connection between the body and the hopper

Turn the drum body and the hopper sealing connection between 2020 - improvement 05 - 05 traditional drum pulper in the structure of the feed end generally consists of rotating drum body and into the hopper, the have turn the flange on the rotating drum, into the hopper set on static flange, and turn the flange and static groove is formed between the flange rubber packing, thus formed in the feed end of the drum pulper packing seal structure. As shown in figure 1. Drum body, however, in turns, rubber packing and turn the flange contact, which will cause the rotation flange and wear of rubber packing, in turn, will reduce the efficiency of equipment and will cause the increase of downtime. Therefore, provide a kind of modified drum pulper, the machine can make the equipment operation efficiency to obtain enhances the better, and can reduce downtime. As shown in figure 2, figure 3, a new type of rotary drum pulper including rotating drum body and into the hopper, turn the drum body is equipped with inlet, feed hopper installed at the inlet, and into the feed hopper channel leads to the inlet, between rotating drum body and the hopper through the labyrinth seal structure to realize seal connection. Among them, the labyrinth seal structure including sealing ring and a circular convex tooth, sealing ring seat is connected with the hopper by bolts, annular convex gear set on the rotating drum body, and the sealing ring and ring protruding teeth axis are around the center of the feeding port Settings. The seal ring seat is equipped with a seal ring to match the annular convex tooth groove, annular convex tooth embedded in the gasket groove, and the annular convex tooth and activity space between the gasket groove. Annular convex tooth including primary teeth and hook, hook department set up in the main gear department, and within the department is located in the gasket groove. Sealing ring seat, of course, can also be connected to the rotating drum body, accordingly the annular convex teeth are set on the hopper; The gasket groove can be set to two or more than two, accordingly the number of annular convex tooth can be consistent with the number of gasket groove, and each ring protruding tooth embedded in the corresponding in the gasket groove, respectively. In addition, the inlet for the conical mouth, the inlet diameter reduced gradually from inner to outer; Need to be sure, the 'inside' concrete corresponds to the feed side structure in the inlet on the rotating drum of the internal side, 'outside' concrete structure corresponds to the incoming end its inlet on the rotating drum of the external side. Into the bottom of the hopper also sets have racks, into the hopper through the racks are fixed. Advantages: due to realize rotating drum body through labyrinth seal structure and seal connections between the hopper, as a result, the rotating drum body rotates, the rotating drum body and won't produce fretting wear between feed hopper, which can improve the efficiency of equipment operation, and can also reduce the downtime. In addition, as a result of labyrinth seal structure, but also convenient disassembly between rotating drum body and into the hopper, is conducive to more easily maintain equipment. （ Light source: guosen machine)
