Embodiment
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
See accompanying drawing 1, a kind of sintered exhauster casing main shaft sealing device that the utility model provides, for main shaft 5 and the sealing of casing 1 position of sintered exhauster, comprising:
Fixed plate, fixed plate and casing 1 are connected; The side of fixed plate and the plane parallel of casing 1 are arranged.
Sealing gasket 2, sealing gasket 2 is fixedly installed between the side of fixed plate and the plane of casing 1; Fixed plate is close in the side of sealing gasket 2; The opposite side of sealing gasket 2 is close to casing 1; Main shaft 5 is close in the bottom surface of sealing gasket 2; Gap between sealing gasket 2 sealed enclosure 1 and fixed plate.
Fixed block, fixed block is connected fixed plate; Fixed block offers groove; Groove and fixed plate form containing space.
Carbocyclic ring 6, carbocyclic ring 6 is arranged on the bottom of containing space; Carbocyclic ring 6 is close to and is set on main shaft 5; Fixed plate is close in carbocyclic ring 6 side; Carbocyclic ring 6 seals the gap between fixed plate and main shaft 5; Carbocyclic ring 6 is close to and is set on main shaft 5, ensures that fixed plate is close in carbocyclic ring 6 side simultaneously, the gap between fixed plate and main shaft 5 is sealed.
Elastic member 3, elastic member 3 is arranged on the top of containing space; The end face of the top squeeze fixed block groove of elastic member 3; The outer peripheral surface of the bottom squeeze carbocyclic ring 6 of elastic member 3.As a kind of preferred embodiment, elastic member 3 is spring.When after carbocyclic ring 6 with the contact surface abrasion of main shaft 5, the pressure of spring can be relied on automatically to compensate, thus continue the effect playing sealing, make the longer service life of sealing device.
Wherein, sealing device achieves the complete seal between the casing 1 of sintered exhauster and main shaft 5 by sealing gasket 2 and carbocyclic ring 6, does not need daily replacing or additional fillers, reduces the air leakage rate of sintering machine of sealing place, thus improves manufacturing efficiency.
As preferably, sealing gasket 2 is fixed on casing 1 by bolt by fixed plate; Fixed block is connected by bolt and fixed plate, sealing gasket 2 and casing 1.Be bolted, can easily fixed disassembly plate, fixed block and sealing gasket 2.
As preferably, the first pin-and-hole is offered in bottom, fixed plate side; The second pin-and-hole offered by the corresponding fixed plate in side of carbocyclic ring 6.
As preferably, seal arrangement also comprises:
Pin 4, the first pin-and-hole is stretched in one end of pin 4, and the other end stretches into the second pin-and-hole; Pin 4, for fixing carbocyclic ring 6, stops carbocyclic ring 6 to follow main shaft 5 and rotates.Pin 4 can prevent carbocyclic ring 6 in rotary moving along main shaft 5, further ensures sealing effect.
Wherein, see accompanying drawing 2, seal arrangement of the prior art adopts the structure of filler spacer ring 7, cooling and lubricating intake pipe 8, oil immersion asbestos packing 9, Stuffing box 10, Gland 11 and axle sleeve 12, full Stuffing box 10 is filled by oil immersion asbestos packing 9, compress Gland 11, make oil immersion asbestos packing 9 pairs of axle sleeves 12 realize sealing, in Stuffing box 10, pass into cooling water by filler spacer ring 7 and cooling and lubricating intake pipe 8 and cool oil immersion asbestos packing 9 and axle sleeve 12.But, have relative movement between oil immersion asbestos packing 9 and axle sleeve 12, produce friction between the two, oil immersion asbestos packing 9 and axle sleeve 12 are are easily worn and torn, working life is short, needs periodic replacement, and friction is large, machine utilization increases, power consumption is large, when after oil immersion asbestos packing 9 and axle sleeve 12 wear out failure, can cause leaking out seriously, reduce productivity, also have serious safety problem.Meanwhile, seal arrangement of the prior art needs in Stuffing box 10, to pass into cooling water, not only waste water resource, if there is water to leak, immerses bearing, by impact lubrication, corrodes bearing, when expending check man and spare part.
