The utility model discloses a priority twice sealing device, seal strength is high, and the clearance between the fixed seal ring sum rotary seal cover can be adjusted, and application scope is wide, long service life.
Description
Technical field
This utility model belongs to rubber plastic pressure initial refining machine component device field, particularly with regard to a kind of combined type automatic sealing device for pressure initial refining machine.
Background technology
The banburying chamber of pressure initial refining machine is airtight, and during work, two rotors turn round relatively, and the annular gap between the rotor diameter of axle and banburying chamber's sidewall is easy material leakage when mixing, in order to prevent the leakage of material, it is necessary to install sealing device at rotor diameter of axle place.
The one " sealing device of rubber pressure initial refining machine " of China publication number CN201143734Y, it is all symmetrical installing labyrinth-type excluder between upper and lower propeller boss hole and the armature spindle of housing two interior plate, described each labyrinth-type excluder is made up of quiet set and the dynamic set convex, concave ring surface of convex, concave ring surface, the quiet set of affixed convex, concave ring surface in propeller boss hole, with quiet set convex, concave ring surface is corresponding, the dynamic set of affixed convex, concave ring surface on armature spindle, and make convex, the scrobicular ring of set can rotate in convex, the scrobicular ring of quiet set.This sealing device structure is simple, it is easy to maintenance to manufacture, and solves the sealing problem of pressure initial refining machine to a certain extent.All the time it is under strong stress yet with masticator rotor, produce the kinestate of flexing deformation therefrom, when causing rotor to rotate, the dynamic labyrinth ring (i.e. the dynamic set of convex, concave ring surface) of its both ends of the surface connection produces axis oscillating, thus changing with the laminating gap of quiet labyrinth ring (i.e. the quiet set of convex, concave ring surface), two labyrinth ring contact wears, greatly reduce its sealing property.
Summary of the invention
The purpose of this utility model is in that to provide a kind of combined type automatic sealing device for pressure initial refining machine that can solve the problem that above-mentioned technical problem.
This utility model is achieved in that a kind of combined type automatic sealing device for pressure initial refining machine, including rotor
Banburying locular wall, described rotor is disposed with threaded sleeve, rotatory sealing set and axle sleeve, it is provided with fixed cover between described threaded sleeve and banburying locular wall, fixing seal ring it is provided with between described fixed cover and ring set, described fixing seal ring and rotatory sealing set contact formation sealing surface, and described ring set couples by stud is removable relative to axle sleeve.
Further, described stud deviates from one end of ring set and is provided with Packing spring, spring cup and nut.
Further, described threaded sleeve is provided with fixedly sleeved synapsis and turns to contrary screw thread with rotor.
As optimization, the contact surface build-up wear-resistant hard alloy of described rotatory sealing set and fixing seal ring.
This utility model adopts successively two seals device, and sealing intensity is high, and the gap between fixing seal ring and rotatory sealing set can regulate, applied widely, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 rotor in figure, 2 threaded sleeves, 3 banburying locular walls, 4 fixed covers, 5 rotatory sealing sets, 6 fixing seal rings, 7 ring sets, 8 studs, 9 axle sleeves, 10 Packing springs, 11 spring cups, 12 nuts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of combined type automatic sealing device for pressure initial refining machine, including rotor 1, banburying locular wall 3, described rotor 1 is disposed with threaded sleeve 2, rotatory sealing set 5 and axle sleeve 9, being provided with fixed cover 4 between described threaded sleeve 2 and banburying locular wall 3, be provided with fixing seal ring 6 between described fixed cover 4 and ring set 7, described fixing seal ring 6 and rotatory sealing set 5 contact formation sealing surface, described ring set 7 couples by stud 8 is removable relative to axle sleeve 9
Described stud 8 deviates from one end of ring set 7 and is provided with Packing spring 10, spring cup 11 and nut 12.
In this utility model, threaded sleeve 2 is provided with fixed cover 4 contact position and turns to contrary screw thread with rotor 1, and when material is from closed chamber to outward leakage, left-hand thread can return in banburying chamber its maximized general, completes preliminary sealing.
Under the effect of spring pressure mechanism, fixing seal ring 6 and rotatory sealing set 5 contact and produce certain pressure, the secondary that can stop material is revealed, wherein Packing spring 10 can regulate its stroke by nut 12,5 touching positions are overlapped in fixing seal ring 6 and rotatory sealing also should arrange lubrication hole, when pressure initial refining machine works, reduces fixing seal ring 6 and the abrasion of rotatory sealing set 5, as preferably, the contact surface build-up wear-resistant hard alloy of 5 and fixing seal ring 6 is overlapped in rotatory sealing.
