Abstract
A ball grinder hydromagnetic sealing device comprises a ring magnet, two high magnetic conduction pole pieces, a non-magnetic conduction casing, a non-magnetic gasket and magnetofluid, wherein the two high magnetic conduction pole pieces are both the ring shape. The ring hole is a little bigger than the outer diameter of the hollow shaft in the ball grinder, and is sleeved on the shaft. The outer diameter is nipped between the magnetic conduction pole piece and the ring magnet having the same outer diameter, and a non-magnetic gasket is between the pole piece and the hollow shaft. The non-magnetic conduction casing connected with one side of a bearing chock is covered on the outer surface of the pole piece, ring magnet and a gasket. The magnetofluid is filled in the gap of the pole piece and the hollow shaft. The device catches up the magnetofluid by the magnetism originating from a permanent magnet, and can stop non-magnetic object passing, further increasing the sealing property.
Description
The utility model relates to the parts on the pebble mill, particularly the seal arrangement of the bearing between pebble mill roller axle and the supporting base.
Pebble mill is operated in the many occasions of dust mostly, and the sealing of its bearing is extremely important.Dual mode is mainly adopted in the sealing of the bearing of pebble mill at present: the one, use skeleton rubber, and stop dust to enter bearing by rubber with tight contact of axle, this structure quick abrasion, sealing effect is very poor; Another kind is the one-way flow sealing, is pressed into butter in the bearing of bearing lateral, its gap between axle and shell is extruded, to stop entering of dust.This method troublesome poeration, waste butter.
The purpose of this utility model just provides a kind of not consumes energy and material, and the life-span is long, the device for sealing magnetic fluid of good sealing effect.
The technical solution of the utility model is: comprise ring magnet, two high magnetic conductive pole pieces, non-magnetic conduction casing, non-magnetic conduction packing ring, magnetic fluid.Two high magnetic conductive pole piece shapes are identical, all are annular, and its looping pit is a bit larger tham the external diameter of pebble mill hollow shaft and is sleeved on this axle.External diameter and magnetic conductive pole piece, the ring magnet that external diameter is identical are clipped between them, between the bearing of the pole shoe of a side and hollow shaft non-magnetic conduction packing ring are arranged.Be with non-magnetic conduction casing in pole shoe, ring magnet and packing ring outside, it is connected with a side of bearing support.In the gap of pole shoe and hollow shaft, be full of magnetic fluid.
In the inner hole surface of described high magnetic conductive pole piece V-shaped groove along circumference being arranged, is zigzag fashion on axial section promptly, also can be rectangle or dovetail groove, to strengthen the magnetic intensity of each end face.
On corresponding to the quill shaft of pole shoe, a magnetic conduction axle sleeve can be set also.
Described ring magnet is also equally distributed along circumference, and many axial magnet constitute.
The utility model has the advantages that: being in operation does not need specialized operations and consumable material, and cost is low, and it holds magnetic fluid by the magnetic that permanent magnet produces, and can stop nonmagnetic object to pass through effectively, has increased sealability.
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing.
Fig. 1 is the skeleton rubber seal arrangement schematic representation of prior art;
Fig. 2 is the one-way flow seal arrangement schematic representation of prior art;
Fig. 3 is the mounting point schematic representation of the utility model on pebble mill;
Fig. 4 is a structural representation of the present utility model.
Referring to Fig. 1, be the skeleton rubber seal arrangement of prior art, basic structure is the rubber ring 3 of band skeleton, its cross section is a ligulate, stops dust to enter bearing by the tip of the tongue with tight contact of axle, at the lip of the tongue a helical spring 4 is arranged.This structure quick abrasion, sealing effect is very poor.
Referring to Fig. 2, be the one-way flow seal arrangement of prior art, in bearing 1, be pressed into butter in the hole 4 in the bearing outside, its gap between axle 5 and shell 2 is extruded, to stop entering of dust.
Referring to Fig. 4, the utility model is installed on the quill shaft 5 at pebble mill roller 6 two ends, is fixed together with bearing spider 2.
In the inner hole surface of described high magnetic conductive pole piece V-shaped groove along circumference being arranged, is zigzag fashion on axial section.Also can be rectangle groove or dovetail groove.
On corresponding to the quill shaft 5 of pole shoe 7 and 9, a magnetic conduction axle sleeve can be set also.
Described ring magnet 8 is also equally distributed along circumference, and many axial magnet constitute.They can be by the non-magnetizer support fixation.
