Background
The vertical mill is a large-scale grinding device, which is widely applied to the industries of cement, electric power, metallurgy, non-metal ore and the like, and the cement factory commonly uses the vertical mill to grind raw materials, coal dust and cement. The vertical mill consists of a separator of a powder concentrator, a grinding roller device, a grinding disc device, a pressurizing device, a speed reducer, a motor, a shell and the like.
The powder concentrator mainly comprises: casing, wind guide blade, powder concentrator rotor, rotor seal, drive arrangement etc.. The material milled by the vertical mill enters the powder concentrator on the upper part from an air duct in the mill, is changed in speed and direction through the air guide blades, and then passes through the centrifugal force provided by the rotating rotor blades and the comprehensive selection of radial wind power, so that qualified fine powder can pass through the gaps of the rotor blades of the powder concentrator and then enters a finished product collecting system through an air outlet on the upper part of the powder concentrator. Unqualified coarse powder which cannot enter the rotor can fall back to the grinding disc for grinding again, and then enters the next grinding cycle.
In the running process of the vertical mill powder concentrator, the rotor continuously rotates under the drive of the motor, the shell does not rotate, and a sealing device is designed in a gap between the rotor and the shell to limit coarse powder from running out of the shell without being filtered by the rotor. The sealing device generally adopts a pneumatic sealing mode, the sealing effect of the existing pneumatic sealing structure is poor, a large number of coarse particles pass through the sealing gap of the rotor in the working process, the powder selecting efficiency of the powder selecting machine is reduced, and the existing vertical mill rotor is inconvenient to replace and difficult to maintain after being sealed and damaged.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a vertical mill selection powder machine rotor and mounting structure of casing can effectually reduce the probability that coarser granule passes through from the rotor seal clearance, improves selection powder efficiency, also is convenient for maintain in the use.
In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a vertical mill selection powder machine rotor and mounting structure of casing, includes selection powder machine casing and the selection powder rotor of vertical setting in selection powder machine casing, is equipped with the opening at the top of selection powder machine casing, and the opening part can be dismantled and be equipped with an annular seal plate, the centre bore department of annular seal plate is connected with a sleeve, and in the air outlet of sleeve downwardly extending entering selection powder rotor end plate, rotating clearance has between sleeve and end plate air outlet, is provided with between selection powder rotor end plate and annular seal plate and prevents that the middlings from getting into the inside seal assembly of rotor between selection powder rotor end plate and the annular seal plate, seal assembly include with selection powder rotor end plate directly or indirectly be connected along the radial polylith guide plate that sets up of selection powder rotor end plate and connect the sealed baffle between adjacent guide plate.
Furthermore, a first flange is arranged on the powder selecting rotor end plate, a second flange is fixedly arranged on the first flange through bolts, and the sealing assembly is arranged on the second flange.
Further, the sealing assembly and the second flange are of an integrated structure.
Further, the sealing baffle is arranged on the inner side of the powder selecting rotor and is higher than the guide plate.
Further, the guide plates are uniformly arranged.
According to the technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses be provided with seal assembly on the selection powder rotor, seal assembly includes along the polylith guide plate of radial setting, has still add seal baffle between the guide plate, and guide plate and seal baffle form radial outside air current along with rotor pivoted in-process, can block the granule effectively and pass through, and seal baffle's setting more can increase this kind and block the effect for sealed effect is better, has improved selection powder efficiency greatly.
2. Through with guide plate, seal baffle and flange integrated design, can dismantle the setting on the rotor, when rotor seal structure wearing and tearing reached the certain degree, conveniently change it, reduced the maintenance cost.
