Abstract
The utility model discloses a ball mill feeding seal device, and belongs to the field of sealing parts. The ball mill feeding seal device structurally comprises a feeding bushing and a feeding pipe. A mechanical seal is arranged between the feeding bushing and the feeding pipe, and comprises a movable ring, a static ring and an elastic element. The movable ring is fixed on a pressing cover through a pin, the pressing cover is connected with the feeding bushing through a bolt, the static ring is arranged on the inner side of the movable ring and the outer side of the feeding pipe, and the elastic element is arranged between the movable ring and the static ring. Compared with the prior art, the ball mill feeding seal device has the advantages of being low in leakage rate, long in service life and maintenance cycle, and the like, and has good popularization and application value.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of device for sealing feeding of ball mill.
Background technique
Pebble mill mostly runs through with supply pipe inside and outside equipment, will have like this circumferential clearance between supply pipe and bushing for feeding, and the slurries in pebble mill will be by gap to outward leakage.Pebble mill inlet seal adopts packing_seal or seal ring sealing mostly at present, and these two kinds sealings are short working life, need to often change, and after use a period of time, leakage rate increase is difficult to meet seal request.
At present, the solution also not had.
Model utility content
Technical assignment of the present utility model is to provide a kind of device for sealing feeding of ball mill for above-mentioned deficiency of the prior art, and this device for sealing feeding of ball mill has the advantages that leakage rate is few, the life-span long, service cycle is long.
The utility model solves the technological scheme that its technical problem adopts: it comprises bushing for feeding and supply pipe, between described bushing for feeding and supply pipe, be provided with mechanical seal, described mechanical seal comprises rotating ring, stationary ring and elastic element, described rotating ring is fixed by a pin on gland, described gland is connected with bushing for feeding by bolt, described stationary ring is arranged on the outside of rotating ring inner side, supply pipe, between described rotating ring and stationary ring, is provided with elastic element.
Described elastic element is spring.
Between described rotating ring and gland, be provided with rotating ring auxiliary seal ring, between described rotating ring and stationary ring, be provided with seal ring, between described stationary ring and supply pipe, be provided with stationary ring auxiliary seal ring.
Device for sealing feeding of ball mill of the present utility model compared to the prior art, there is following outstanding beneficial effect: supply pipe and bushing for feeding install additional after mechanical seal, sealability is reliable, amount of leakage is little, long service life, low in energy consumption, must often not keep in repair, and can be adapted to process automation and high temperature, low temperature, high pressure, vacuum, high speed and various strong corrosive media, containing the features such as seal request of the harsh operating modes such as solid particle medium.
