Description
Technical Field
The utility model relates to the technical field of coal water slurry mills, in particular to a bolt sealing device for a cylinder body of a coal water slurry mill.
Background
The feeding of the wet rod mill for coal water slurry is that coal, water and additives are fed into a horizontal mill cylinder through a coal mill inlet spiral feeding cylinder, rubber lifting bars arranged on the inner wall of the cylinder, and steel lining plates on the two sides of the cylinder and on the two sides of the cylinder are lifted to a certain height along with the lifting bars, a mill rotating steel bar falls down, raw coal is ground into coal water slurry with a certain granularity ratio and a certain coal slurry concentration, and the coal water slurry is fed into the next working procedure to be used as a raw material for production after passing through a coal mill outlet cylinder screen; the two sides of the inner wall of the cylinder body and the two ends of the cylinder body are just connected through bolts penetrating through the cylinder wall. In the existing situation, the phenomenon of poor sealing occurs, so that the problem of poor environmental sanitation caused by on-site slurry leakage is caused; the problem of damage to the big and small gears of the mill after slurry leakage; and after slurry leakage, the dry oil of the large and small gears is polluted, and the problem of replacement is frequently cleaned.
Disclosure of Invention
Aiming at the problems, the utility model provides the bolt sealing device for the cylinder body of the coal water slurry mill, which has good sealing effect and achieves the effect of preventing the coal slurry from leaking during the use process. The technical proposal is as follows:
the utility model provides a coal slurry mill barrel bolt sealing device, includes welt, barrel, from interior outside through the bolt through connection, barrel surface welding interior taper external member, establishes taper rubber seal on the interior taper external member, and the bolt runs through interior taper external member, taper rubber seal to fasten through the nut on taper rubber seal.
And a gasket is arranged between the conical rubber sealing piece and the nut.
The gasket is an inverted bowl-shaped gasket, and when the nut is fastened, the bowl-shaped gasket can provide downward and inward pressure for the conical rubber sealing element, so that the sealing effect is ensured.
The nut is used for pressing the conical rubber sealing element, the conical rubber sealing element can be well attached to the inner conical surface of the inner conical sleeve, and meanwhile, the conical rubber sealing element and the bolt can be well attached and sealed through extrusion.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
The specific embodiment is as follows:
the utility model is further described below with reference to the drawings and examples.
Example 1
As shown in figure 1, the bolt sealing device for the cylinder body of the coal water slurry mill comprises a lining plate 1 and a cylinder body 2, wherein the lining plate is connected with the cylinder body 2 from inside to outside in a penetrating manner through a bolt 3, an inner conical sleeve piece 4 is welded on the outer surface of the cylinder body 2, a conical rubber sealing piece 5 is arranged on the inner conical sleeve piece 4, an inverted bowl-shaped gasket 6 is arranged on the conical rubber sealing piece 5, the bolt 3 sequentially penetrates through the inner conical sleeve piece 4, the conical rubber sealing piece 5 and the bowl-shaped gasket 6, and the bolt 3 is fastened through a nut 7, so that the conical rubber sealing piece 5 has a good fitting sealing effect with the conical sleeve piece 4 and the bolt 3.
The above description is not intended to limit the utility model in any way, and any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model without departing from the technical scope of the present utility model.
Claims (3)
1. The utility model provides a coal slurry mill barrel bolt sealing device, includes welt, barrel, from interior outside through the bolt through connection, its characterized in that, interior taper external member of barrel surface welding establishes taper rubber seal on the interior taper external member, and the bolt runs through interior taper external member, taper rubber seal to fasten through the nut on taper rubber seal.
2. The screw bolt sealing device for the cylinder of the coal water slurry grinder according to claim 1, wherein a gasket is arranged between the conical rubber sealing element and the nut.
