Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-rotor, 2-box, 3-protective cover, 4-wear-resistant cover, 5-material-blocking disk, 6-reflux groove and 7-wear-resistant cover.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A shaft seal device of a medium chain breaker comprises a box body 2; the outer wall on install guard shield 3, the mid-mounting of guard shield 3 has wear-resisting cover 7, wear-resisting cover 4 is installed at the center of wear-resisting cover 7, wear-resisting cover 4 is installed on the step axle of rotor 1, the inboard of wear-resisting cover 4 is kept off the charging tray 5 in addition and is installed on the step axle. The box body 2, the shield 3, the wear-resistant sleeve 4 and the material blocking disc 5 form an annular cavity.
Keep off charging tray 5 fixed mounting and the disc hugs closely the step face of axle on the step axle, the disc contacts with box 2, the center of keeping off charging tray 5 still is provided with solid fixed ring. The material blocking plate 5 is arranged at the step shaft, so that the material cannot slip out through a gap between the material blocking plate 5 and the step shaft.
Wear-resisting cover 4 fixed mounting just is keeping off the outer end of material dish 5 on rotor 1, reduces the material and directly falls into wear-resisting cover 4 and wear-resisting cover 7 after keeping off material dish 5 and block that processing has annular arch on the terminal surface of wear-resisting cover 4, and the bellied cross-section of annular is the coniform and stretches into in wear-resisting cover 7. Seal the box through the arch between wear-resisting cover 7 and the wear-resisting cover 4, wear-resisting cover 7 is fixed and is made wear-resisting cover 4 can be at wear-resisting cover 7 internal rotation on the guard shield, through some contact department processing of guard shield 3 and wear-resisting cover 7 has the backward flow groove 6 that runs through guard shield 3 and wear-resisting cover 7 and become the obtuse angle with the inner wall of guard shield 3. The materials entering the wear-resistant sleeve 4 and the wear-resistant cover 7 can return to the box body 2 through the return chute 6.
One end of the protective cover 3 is arranged on the box body 2, and the other end of the protective cover is connected with the material blocking disc 5. The shield 3 makes a cavity formed among the box body 2, the shield 3, the wear-resistant sleeve 4 and the material blocking disc 5 to buffer materials which are not blocked by the material blocking disc 5.
And a part of the inner wall of the shield 3 is processed into an inclined plane parallel to the return groove 6 on the shield, and the inclined plane is processed on the radial outer side of the return groove 6. The material entering the cavity returns to the interior of the box body through the inclined plane and the backflow hole on the box body 2 and on the inclined plane of the shield 3.
The contact surfaces of the box body 2 and the material blocking disc 5 are both side surfaces and are all processed into inclined surfaces which are parallel to each other. The inclined planes parallel to each other can avoid the centrifugal force generated by the material caused by the rotation of the rotor, and the material directly goes out of the material blocking plate 5.
A backflow groove 6 which penetrates through the shield 3 and the wear-resistant cover 7 and forms an obtuse angle with the inner wall of the shield 3 is machined at a part of the contact part of the shield 3 and the wear-resistant cover 7.
And a backflow hole is processed on the box body 2 and is processed at the inclined plane of the shield 3.
The principle of the utility model is that: avoid the direct wear-resisting cover 4 of material and sealing member contact and wear-resisting cover 7 through keeping off charging tray 5, reduce the wearing and tearing that the material got into the sealing member with higher speed sealing member, the loss of material has also been reduced, the material of slipping out from the gap between keeping off charging tray and the box 2, be left between sealing member and the box 2 under the effect of guard shield 3, through the rotation of rotor, the backward flow hole of processing returns in the box from box 2, and the material that gets into between wear-resisting cover and the wear-resisting cover can also pass through between wear-resisting cover and the guard shield in the rotatory in-process of rotor can also withdraw in the box 2 through the backward flow groove.
