Abstract
The utility model provides a scraper centrifuge with a main shaft seal device, which is composed of a main shaft (1), a bearing box (2), a spiral casing (3), an end cover (4) and a seal sleeve gasket (5). The spiral casing (3) is coupled with the main shaft (1), and the end cover (4) and the seal sleeve gasket (5) are fixed on the spiral casing (3) in assemblage successively. A channel is arranged on the bearing box (2) and the end cover (4), which can reach the surface of the spiral casing (3). The structure adopted by the utility model can thus prolong the period of usage of the scraper centrifuge because the structure can improve the seal ability and is stable and reliable.
Description
Technical field
The utility model relates to a kind of centrifugation machinery, especially relates to a kind of scraper centrifugal machine with main shaft 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 drive the rotary drum running, and main shaft seal is in order to cut off being connected of rotary drum side and bearing guard, to avoid the lubricant pollution material, and the liquid that also prevents the rotary drum side enters bearing influences the operation of a machine.Centrifuge works long hours in the use of reality mostly, and than higher, so the sealing of spindles effect directly influences the life-span of using producer's service life and centrifuge to the operation of a machine reliability requirement.At present, traditional main shaft seal has only adopted one backbone sealing ring with labyrinth seal, and effect is not very desirable, and reliability has much room for improvement.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can improve main shaft seal effect, reliable and stable scraper centrifugal machine.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises main shaft, bearing housing, screw-casing, end cap and sealing spacer, screw-casing is sleeved on the main shaft, end cap is sleeved on the screw-casing with the sealing spacer successively, on bearing housing and end cap, be provided with the duct, the screw-casing surface of leading to, duct.
As to a kind of improvement of the present utility model, can seal spacer and be provided with the helixseal structure.
As to another kind of improvement the of the present utility model, the expanded rubber circle can be installed on end cap.
The said structure that the utility model adopts, owing to can improve sealing effectiveness, reliable and stable, thus can prolong the service life of scraper centrifugal machine.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
The specific embodiment
By accompanying drawing as can be known, this scraper centrifugal machine with main shaft sealing device comprises main shaft 1, bearing housing 2, screw-casing 3, end cap 4 and sealing spacer 5, screw-casing 3 is sleeved on the main shaft 1, and with main shaft 1 running, end cap 4 is sleeved on the screw-casing 3 successively with sealing spacer 5, on bearing housing 2 and end cap 4, be provided with the duct, screw-casing 3 surfaces of leading to, duct.In actual mechanical process, lubricating oil enters from oil inlet pipe 6, lubricating bearings and main shaft, feed nitrogen from air inlet 7, gas arrives screw-casing 3 surfaces along the duct, form press belt on screw-casing 3 surperficial circumferencial directions, stop lubricating oil from the bearing direction to rotary drum direction seepage.The utility model can seal spacer 5 and be provided with helixseal structure 8, multiple groove design can stop lubricating oil from the bearing direction to rotary drum direction seepage, the lubricating oil in the groove flows back to the bearing end by the duct that communicates with groove.The utility model can also be equipped with expanded rubber circle 9 on end cap 4, can further cut off being connected of rotary drum side and bearing guard.In addition, when high temperature and high pressure gas when sterilization carried out in shutdown, the pressure of gas causes expanded rubber circle 9 to be close at the bottom of the rotary drum 10, makes rotary drum partly form the space of a relative closure, has guaranteed the validity of sterilization.
Claims (3)
1, a kind of scraper centrifugal machine with main shaft sealing device, comprise main shaft, bearing housing, screw-casing, end cap and sealing spacer, screw-casing is sleeved on the main shaft, end cap is sleeved on the screw-casing with the sealing spacer successively, it is characterized in that: on bearing housing and end cap, be provided with the duct, the screw-casing surface of leading to, duct.
2, a kind of scraper centrifugal machine with main shaft sealing device according to claim 1 is characterized in that: the sealing spacer is provided with the helixseal structure.
