Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description.
In one embodiment, there is provided a kind of wet ball mill sealing structure, after the assembling of wet ball mill sealing structure
As shown in Figure 1 and Figure 2, sealing structure is arranged at the charging position of wet ball mill to position relationship, charging position be provided with into
The feed pipe 1 of material mouth insertion ball mill body 2；
As shown in figure 3, sealing structure is specifically included：
The end cover 3 for being fixed on charging aperture and being sheathed on outside feed pipe 1, it has been internally formed the first groove and second
Groove；External seal tooth is formed with wherein the second groove.As shown in Figure 4,5, end cover 3 using can split, it is including symmetrical
Two end cap halfbodies, the end cap halfbody is fixedly connected by helicitic texture.End cover 3 passes through uniform helicitic texture 4
It is fixed on charging aperture.By taking a practical structures as an example, two end cap halfbodies are connected using two connecting bolt M16 being arranged symmetrically,
After the end cover of end cap halfbody composition one, it is connected using 4 M12 fixing bolts between mill body 2.Certainly, it is above-mentioned
Practical structures are only illustrated as an example, and during concrete application, specification, the quantity of connecting bolt and fixing bolt can be according to wet
The model of formula ball mill, specification are chosen.
In addition, also including axle sleeve 5 of the fixed cover located at charging pipe outer wall, it is externally formed with coordinating with foregoing external seal tooth
The interior sealing tooth of installation, the two collectively forms labyrinth seal 7.In addition, to ensure that slurries are stitched not between axle sleeve 5 and feed pipe 1
Gap is oozed out, and the 3rd groove 51, built-in sealing ring are machined with axle sleeve 5, it is ensured that operation bottom bracket axle inner side No leakage.With a tool
As a example by body structure, the 3rd groove is located at using the O-shaped rubber seal plug of 3MM or so, certainly, the only conduct of above-mentioned practical structures is shown
Example explanation, during concrete application, sealing ring specification can be according to the selection of dimension of feed pipe 1.As schemed, the end of axle sleeve 5 is provided with
Fixed fastening bolt, fastening bolt is the pretension for being capable of achieving axle sleeve 5 and feed pipe 1.
Additionally, the inside of end cover 3 and the matching part of feed pipe 1, i.e. the first groove, are provided with packing seal, with
As a example by one practical structures, packing seal is graphite packing, and packing size is 20mm × 20mm, end cover 3 and mill body 2
After the completion of assembling, packing can be pre-compressed and deform, and play a part of first sealing.
Labyrinth sealing 7 is formed between aforementioned seal end cap 3 and axle sleeve 5, by taking a practical structures as an example, sealing tooth transverse tooth thickness is
3mm, the gap between sealing tooth is 1mm, and gap is 3mm between tooth top and bottom of the tooth, can be by adjusting axle sleeve and sealing during assembling
Position relationship between end cap, it is ensured that do not rubbed mutually between sealing tooth.Certainly, above-mentioned practical structures only illustrate as an example,
During concrete application, sealing tooth gauge lattice can be according to the selection of dimension of feed pipe.
When the effect of packing_seal 6 difference or failure, the material exosmosed to feed end enters labyrinth sealing 7, in labyrinth type
Preferable sealing function can be played under sealing principle of hydrodynamics effect.
As described above, the total three seals device of the wet ball mill sealing mechanism of the present embodiment, twice dynamic sealing is quiet together
Sealing, graphite packing constitutes twice dynamic sealing with labyrinth sealing, it is ensured that peace in the sealing problem of material, axle sleeve when grinding machine rotates
The sealing ring of dress is static seal, it is ensured that material is leaked not between axle sleeve and feed pipe.
Verified by Practical Project, in Henan, power plant desulphurization system wet ball mill is using the close of above-described embodiment description
After seal structure, sealing effectiveness is good, it is only necessary to annual that graphite packing is carried out to ensure that sealing structure is close by checking replacing once
Envelope effect stability.
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.It is based on
Embodiment in the utility model, it is all that those of ordinary skill in the art are obtained under the premise of creative work is not made
