Abstract
The invention relates to a sealing element, in particular to the sealing element for a compression roller assembly of a granulator. The technical scheme includes that the sealing element for the compression roller assembly of the granulator comprises a sealing element body and a central hole (7), wherein the sealing element body is formed by an outer body and an inner body A (3), the inner body A (3) comprises a circular boss A (2) protruding leftwards, the central hole (7) is reserved in the middle of the sealing element body, a mounting hole (8) is reserved between the outer body and the inner body A (3), a first circular boss (4), a second circular boss (5) and a third circular boss (6) are arranged on the right side of the inner body A (3). By above technical scheme, the sealing element for the compression roller assembly of the granulator has the advantage that the right side of the inner body A (3) of the sealing element is shaped in a curved surface, and sealing effect is improved.
Description
Technical field
The present invention relates to a kind of seal, particularly a kind of compression roller of granulator assembly seal.The invention belongs to mechanical equipment technical field.
Background technology
The operation principle of ring die pelleter is to utilize the strong squeezing action of ring mould and pressure roller; with living beings clamp-on gradually the ring mould nib in and in nib, be shaped; because continuously extruded between the mould roller of living beings; material after the shaping constantly is column from nib discharges, and then is cut into the particle of Len req by cutting knife.
Ring die pelleter mainly is comprised of motor, the empty axle of transmission, pressing mold and pressure roller.For the ring die pelleter of belt pulley transmission, motor drives the empty axle rotation of transmission by belt pulley, and the empty axle of transmission drives pressing mold again or/and the pressure roller rotation.For gear-driven ring die pelleter, motor is by the empty axle rotation of gear driven transmission, and the empty axle of transmission drives pressing mold again or/and the pressure roller rotation.
Existing compression roller of granulator assembly with seal as shown in Figure 2; it comprises seal body and centre bore 7; seal body is protruded to the left and is become the endosome 10 of circular boss A2 to consist of with containing by containing the ectosome that protrudes to the right and become circular boss B9, and the hole 7 centered by the centre of seal body.It is mainly not enough: because the right side of seal endosome 10 is planes, sealing effectiveness is poor.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of compression roller of granulator assembly seal of good sealing effect is provided.
For achieving the above object; the present invention is by the following technical solutions: a kind of compression roller of granulator assembly seal; it comprises seal body and centre bore; seal body is protruded to the left and is become the endosome A of circular boss A to consist of with containing by ectosome; hole centered by the centre of seal body; also be provided with installing hole between described ectosome and the endosome A, the right side of described endosome A is provided with the first circular boss, the second circular boss and the 3rd circular boss.
Further, the protrusion height of described the first circular boss〉protrusion height of described the second circular boss, the protrusion height of the protrusion height of described the second circular boss=described the 3rd circular boss.
Further, described ectosome is to contain the ectosome that protrudes to the right and become the conial ring shape boss.
Because adopt technique scheme, the present invention has following beneficial effect:
1, three layers of boss make the right side of seal endosome A become curved surface, form the labyrinth sealing road, have improved the sealing effectiveness of seal, and sealing is reliable, and airtight quality is good.
2, the protrusion height of the first circular boss〉protrusion height of the second circular boss, the protrusion height of the protrusion height of the second circular boss=the 3rd circular boss further facilitates processing, improves the sealing effectiveness of seal.
3, adopt the conial ring shape boss, make things convenient for seal to be installed into the compression roller of granulator assembly, convenient use, maintenance.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the compression mold cover structural representation of prior art.
Among the figure: 1, conial ring shape boss, 2, circular boss A, 3, endosome A, the 4, first circular boss, the 5, second circular boss, the 6, the 3rd circular boss, 7, centre bore, 8, installing hole, 9, circular boss B, 10, endosome B.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1; a kind of compression roller of granulator assembly seal; it comprises seal body and centre bore 7; seal body is protruded to the left and is become the endosome A3 of circular boss A2 to consist of with containing by containing the ectosome that protrudes to the right and become conial ring shape boss 1; the hole 7 centered by the centre of seal body; also be provided with installing hole 8 between ectosome and the endosome A3, the right side of endosome A3 is provided with the first circular boss 4, the second circular boss 5 and the 3rd circular boss 6.
Wherein: the protrusion height of the first circular boss 4〉protrusion height of the second circular boss 5, the protrusion height of the circular boss 6 of the protrusion height of the second circular boss 5=3rd.
Owing to adopt three layers of boss, and the protrusion height of the first circular boss〉protrusion height of the second circular boss, the protrusion height of the protrusion height of the second circular boss=the 3rd circular boss, make the right side of seal endosome A become curved surface, and near centre bore, curved surface rise and fall little, away from centre bore, curved surface rises and falls large, progressively improves the sealing effectiveness away from the seal of central hole, improves the sealing effectiveness of whole seal.
Adopt the conial ring shape boss, make things convenient for seal to be installed into the compression roller of granulator assembly, convenient use, maintenance.
The invention is not restricted to above-described embodiment, the technical scheme that all employings are equal to replacement or equivalence replacement formation also all belongs to the scope of protection of present invention.
