Abstract
The utility model relates to a dustproof sealing device used for a cone crusher, which is characterized in that a moving cone is provided with a ring groove, a sealing ring is arranged in the ring groove, and a gap is formed between the sealing ring and a dustproof balance ring for matching. When being used, the moving cone of the dustproof sealing device is provided with the ring groove, and an O-shaped sealing ring is installed in the ring groove. After being assembled, a matched gap of 0 mm to 0.5 mm is retained between the O-shaped sealing ring and the dustproof balance ring. During the machine operation process, after sealing grease in a T-shaped groove is thrown away, the O-shaped sealing ring can fulfill favorable sealing action.
Description
Technical field:
The utility model relates to the technical field of disintegrating machine, and specifically a kind of industrial and mining enterprises are used for the dust seal device in the gyratory crusher of broken material.
Background technology:
All be provided with dust-proof sealing structure in the employed gyratory crusher in the production practices at present, purpose is to prevent that outside dust from entering machine intimate, with the cleaning of maintenance internal lubrication oil, so the quality of dust-proof sealing structure is very important for the normal operation of gyratory crusher.Dust prevention has various ways, the dissimilar dust preventions that circular cone adopted is also different, for example spring cone crusher adopts water-stop or the grease-added sealing of elastic sealing ring, single-cylinder hydraulic circle conic crusher adopts the pressure reduction sealing to add the dust ring sealing more, the high-performance gyratory crusher then adopts the grease-added sealing of T-shape groove (referring to Fig. 1), when machine run, the speed rotation that dustproof balance ring 2 changes with per minute more than 400.Grease in its seal groove is thrown out of outside the groove under action of centrifugal force, has not had grease, and the fit clearance between mantle and the dustproof balance ring is about 3mm, and this gap is bigger, is difficult to play the dust seal effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved dust seal device that is used for gyratory crusher, and it can overcome the some shortcomings of high-performance gyratory crusher dust seal poor effect in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of dust seal device that is used for gyratory crusher, it mainly comprises mantle and dustproof balance ring, it is characterized in that: mantle is provided with annular groove, be provided with sealing ring in the annular groove, form matched in clearance between sealing ring and the dustproof balance ring.
Mantle of the present utility model is provided with annular groove during use, " O " shape sealing ring is packed in the annular groove, the fit clearance that keeps 0～0.5mm between assembling back " O " shape sealing ring and the dustproof balance ring, in the machine operation procedure, after the packing grease in the T-shape groove was thrown out of, " O " shape sealing ring can play good sealing function.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram
Fig. 2 is the structural representation of the utility model one embodiment
Fig. 3 is a user mode reference diagram of the present utility model
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises mantle 1 and dustproof balance ring 2, and its difference with the prior art is: mantle is provided with annular groove, is provided with sealing ring 3 in the annular groove, forms matched in clearance between sealing ring and the dustproof balance ring.Sealing ring adopts rubber " O " shape sealing ring.Gap between sealing ring and the dustproof balance ring is at 0-0.5mm.Mantle is provided with "T"-shaped projection, and dustproof balance ring is provided with the groove that matches with "T"-shaped projection.
In force, the size of annular groove will be complementary with the size of " O " shape sealing ring on the mantle, to ensure that " O " shape sealing ring after the assembling can firmly be fastened in the groove, and and the fit clearance between the dustproof balance ring is between 0～0.5mm, so both can guarantee the mutual operation between mating parts, can play the good dust-proof effect again.In machine is running up process, even if after the packing grease in the T-shape groove was thrown out of, " O " shape sealing ring still can play good sealing function.
