The utility model solves the technological scheme that its technical problem adopts: a kind of shaft sealer of powder mixer, be arranged on the body of mixing machine, comprise the hermetic sealing substrate being fixed on body, hermetic sealing substrate is connected with sealing seat, the main shaft of mixing machine runs through sealing seat center, wear-resistant sleeve is fixed with around main shaft in described sealing seat, the packing being pressed in hermetic sealing substrate side is provided with between wear-resistant sleeve periphery and sealing seat endoporus, the pressure ring compressing packing is embedded with away between the wear-resistant sleeve periphery of the packing opposite side of hermetic sealing substrate and sealing seat endoporus, sealing seat offers the vent passing into pressed gas in the gap between packing and wear-resistant sleeve.
For preventing powder from entering packing inside, described packing is spaced two groups, the wear-resistant sleeve between two groups of packings is set with the spacer ring that can prevent granular material from entering packing inside, spacer ring offers the radial hole communicated with vent.
For convenience of the pretightening force of adjustment pressure ring, described sealing seat has adpting flange, wear-resistant sleeve is set with the pressing plate being pressed in pressure ring side, and a screw bolt is threaded with hermetic sealing substrate through after pressing plate and adpting flange successively again.
Further, change wear-resistant sleeve for convenience, described pressure ring is the split-type structural of two semicircular ring synthesis.
Described wear-resistant sleeve is arranged on after on main shaft and is fixed by Cock screw.
The beneficial effects of the utility model are: the utility model is simple and practical, fast easy to maintenance, utilize the wear resistance of wear-resistant sleeve itself to be better than the characteristic of main shaft, and when after wear-resistant sleeve long-play, wear-resistant sleeve can be changed separately.By arranging packing between sealing seat and wear-resistant sleeve, thus play good sealing effect, and in the gap between packing and wear-resistant sleeve, the gas of certain pressure is passed into by vent, prevent granular material from entering packing inside, ensure that granular material is not contaminated.

Embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings illustrate basic structure of the present utility model all in a schematic way, and therefore it only shows the formation relevant with the utility model.
The shaft sealer of a kind of powder mixer as shown in Figure 1, be arranged on the body 1 of mixing machine, comprise the hermetic sealing substrate 2 being fixed on body 1, hermetic sealing substrate 2 is connected with sealing seat 3, described sealing seat 3 comprises annular sleeve and is fixed on the adpting flange 11 of annular sleeve periphery, and the main shaft 4 of mixing machine runs through the annular sleeve center installation of sealing seat 3.
Wear-resistant sleeve 5 is fixed with around main shaft 4 in the annular sleeve of described sealing seat 3, the wear resistance of this wear-resistant sleeve 5 itself is better than main shaft 4, relatively rotate for preventing from installing between rear wear-resistant sleeve 5 and main shaft 4, described wear-resistant sleeve 5 is arranged on after on main shaft 4 and is fixed by Cock screw 14.Being provided with the packing 6 being pressed in hermetic sealing substrate 2 side between described wear-resistant sleeve 5 periphery and the annular sleeve endoporus of sealing seat 3, being acted on by packing 6, ensure that the reliable sealing of main shaft 4 when relatively rotating.Described packing 6 is spaced two groups, wherein one group is three, one group is two, nearly hermetic sealing substrate 2 side of ternary packing 6 is arranged, wear-resistant sleeve 5 between above-mentioned two groups of packings 6 is set with the spacer ring 9 that can prevent granular material from entering packing 6 inside, the pressure ring 7 compressing packing 6 is embedded with between wear-resistant sleeve 5 periphery outside the packing 6 of two group and sealing seat 3 endoporus, described pressure ring 7 is the split-type structural of two semicircular ring synthesis, conveniently after wear-resistant sleeve 5 damages, changes wear-resistant sleeve 5.
Described sealing seat 3 offers the vent 8 passing into pressed gas in the gap between packing 6 and wear-resistant sleeve 5, spacer ring 9 offers the radial hole 10 communicated with vent 8, described radial hole 10 is four, uniform along spacer ring 9 circumference, pass through vent 8 in the course of the work through radial hole 10, in the gap between packing 6 and wear-resistant sleeve 5, pass into the gas of certain pressure, can prevent granular material from entering packing 6 inner, ensure that granular material is not contaminated.
