The core of this application is to provide a sealing device for vertical axle, can solve current vertical mill when processing the powder material, behind the powder material through the vertical scroll clearance, lead to the operation of vertical axle to break down, and then the problem that makes the life of vertical mill shorten.

Fig. 1 is a schematic view illustrating an installation of a sealing device according to an embodiment of the present invention; fig. 2 is a top view of a sealing device according to an embodiment of the present invention; fig. 3 is a schematic structural view of a sealing device according to a first embodiment of the present invention; fig. 4 is a schematic structural view of a sealing device according to a second embodiment of the present invention.

The first embodiment is as follows:

as shown in fig. 1-3, the sealing device for a vertical shaft provided by the embodiment comprises a base 1 provided with a driving mechanism, a shell 2 arranged above the base 1 is sleeved outside a vertical shaft 3 and provides protection for the vertical shaft, the sealing mechanism is arranged at the upper end of the vertical shaft 3, materials normally fall from the upper end of the vertical shaft 3, and therefore the sealing device prevents dust and impurities from entering a gap at the upper end of the vertical shaft. Of course, the sealing device provided by the application is not only suitable for a vertical mill, but also suitable for vertical shaft equipment with a vertical structure.

Specifically, sealing device is including dismantling end cover 4 of connection on casing 2, as shown in fig. 3, and end cover 4 cup joints in casing 2 to in order to conveniently dismantle and install, as further scheme, be provided with fixed through-hole on the end cover 4, install fastening tapping 8 on the fixed through-hole, fastening tapping 8 is connected with casing 2. Therefore, the end cap 4 can be fixed on the housing 2, and when disassembly is needed, the disassembly process can be completed only by disassembling the fastening tapping 8. As a further alternative, as shown in fig. 2, the number of the fixing through holes is plural, and the fixing through holes are installed along the circumferential direction of the end cover 4, and one fastening tap 8 is installed in each fixing through hole. End cover 4 is connected with casing 2 through a plurality of fastening tappings 8 for the installation is more firm, avoids the vertical scroll 3 to take place to remove when the operation, casing 2.

Specifically, a vertical shaft 3 penetrates through a mounting hole 5 formed in the center of the end cover 4, and a sealing disc is arranged in the mounting hole 5. The sealed dish is including installing the graphite packing 6 of 5 positions departments in the mounting hole, and the top of graphite packing 6 can be dismantled and be connected with packing pressure disk 7. The arrangement of the sealing disc effectively prevents dust from falling into the gap, the graphite packing 6 provides better sealing performance at the mounting hole 5, and meanwhile, the abrasion with the vertical shaft 3 can be reduced; graphite pressure disk 7 makes graphite packing 6 and end cover 4 in close contact with on the one hand, provides sealed effect, and on the other hand provides further sealed to the clearance in the upper end of graphite packing 6 for can carry out double-deck sealing, further increase sealed effect. As a further alternative, as shown in fig. 3, a sealing disc is located at the upper end of the end cover 4, and the packing pressure plate 7, the graphite packing 6 and the end cover 4 are jointly connected in the vertical direction by fastening bolts 9. The packing pressure plate 7, the graphite packing 6 and the end cover 4 are connected together through the fastening bolt 9, and then the installation and the disassembly are simpler and more convenient.

Example two:

in the prior art, the vertical shaft is usually vertically installed, and when in use, materials easily fall into the vertical shaft from the center position of the shaft. The sealing device provided by the embodiment has the advantages that the sealing device is arranged at the upper end of the vertical shaft 3 arranged in the shell 2 to realize the sealing effect, so that materials are prevented from entering the center of the vertical shaft; meanwhile, the sealing means includes an end cap 4 detachably attached to the housing 2 for performing a closing seal at the upper end of the housing 2 and for installing the sealing means. When the installation, the central point of end cover 4 puts and is provided with mounting hole 5, and vertical scroll 3 runs through the setting in mounting hole 5, and 5 positions of mounting hole department are provided with sealed dish, and sealed dish can be dismantled including installing the graphite packing 6 of 5 positions of mounting hole departments, graphite packing 6's top and be connected with packing pressure disk 7.
