Abstract
The utility model discloses a scraper centrifuge with a clearance adjustable sealing device, which comprises a spindle (1), a front gland (2) and the clearance adjustable sealing device. The sealing device consists of a movable adjusting sheath (3), a gland (4), a sealing ring (5), a spindle sheath (6) and a spring (7), wherein the movable adjusting sheath (3), the gland (4) and the spindle sheath (6) are sleeved on the spindle (1), the sealing ring (5) is arranged between the gland (4) and the spindle sheath (6), the spring (7) is arranged between the gland (4) and the movable adjusting sheath (3), and the movable adjusting sheath (3) closely contacts with the bottom of a drum (8) under elasticity action of the spring (7). By aid of the above structure, a clearance between the drum and the front gland can be adjusted optionally, the spindle can be guaranteed against being corroded by corrosive liquid and gas, and then service life of the scraper centrifuge can be prolonged.
Description
Technical field
The utility model relates to a kind of centrifugation machinery, especially relates to a kind of scraper centrifugal machine with adjustable clearance sealing device.
Background technology
Scraper centrifugal machine mainly is made up of support, workspace location and power-section unit.Junction in workspace location and power-section unit, main shaft drives the rotary drum running, in order to cut off being connected of rotary drum side and bearing guard, avoids the lubricant pollution material, the liquid that also prevents the rotary drum side enters bearing influences the operation of a machine, often adopts sealing device between rotary drum and preceding gland.At present, adopt the labyrinth seal form between rotary drum and preceding gland, though this sealing is friction not, service time is long, but must there be the gap in this sealing, can not sealing gas, be not suitable for using in pharmacy, chemical industry etc. having in the environment of damp, can not guarantee that especially main shaft is not subjected to corrosive liquid and gas pickling.After the long-time running of scraper centrifugal machine, this sealing device can make seal failure because of the wearing and tearing of sealing ring, influences the service life of machine.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can the free adjustment rotary drum and preceding gland between the scraper centrifugal machine in gap.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises the sealing device that main shaft, preceding gland and adjustable gaps are whole, the whole sealing device of described adjustable gaps is adjusted sheath, gland, sealing ring, main shaft sheath and spring by activity and is formed, movable sheath, gland and the main shaft sheath adjusted is enclosed within on the main shaft, sealing ring is arranged between gland and the main shaft sheath, spring is arranged on gland and movable the adjustment between the sheath, and the movable sheath of adjusting closely contacts with the bottom of the drum under the spring force effect.
The said structure that the utility model adopts, can the free adjustment rotary drum with preceding gland between the gap, avoided because rotary drum taper fit error produces the gap, particularly can sealing gas, the assurance main shaft is not subjected to corrosive liquid and gas pickling.In addition, the sealing device that this adjustable gaps is whole can prolong the service life of scraper centrifugal machine because not wearing and tearing can not make seal failure because of the wearing and tearing of sealing ring.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that I place partial enlarged drawing among Fig. 1
The specific embodiment
By accompanying drawing as can be known, this scraper centrifugal machine with adjustable clearance sealing device comprises the sealing device that main shaft 1, preceding gland 2 and adjustable gaps are whole, the whole sealing device of described adjustable gaps is adjusted sheath 3, gland 4, sealing ring 5, main shaft sheath 6 and spring 7 by activity and is formed, movable sheath 3, gland 4 and the main shaft sheath 6 adjusted is enclosed within on the main shaft 1, sealing ring 5 is arranged between gland 4 and the main shaft sheath 6, spring 7 is arranged on gland 4 and movable the adjustment between the sheath 3, and the movable sheath 3 of adjusting closely contacts with rotary drum 8 bottoms under spring 7 elastic force effects.Gland 4 is pressed in sealing ring 5 on the main shaft sheath 6, and the movable sheath 3 of adjusting is pressed in rotary drum 8 bottoms by spring 7, and the pretightning force effect by spring 7 makes the movable sheath 3 of adjusting tightly be fitted in the bottom of the drum, reaches the effect of sealing.The utility model is with the described scope of soverlay technique scheme; and the various modification of claim scope and equivalence variation; under the prerequisite that does not depart from the technical solution of the utility model, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
Claims (1)
