Abstract

The utility model relates to a shaft sealing device of a horizontal scraper centrifuge, which includes a non-contact seal, a contact seal, a rotating shaft and a bearing gland, wherein the shaft sealing device of the horizontal scraper centrifuge is formed by the non-contact seal and the contact seal both arranged on the rotating shaft; the non-contact seal consists of a moving ring and a static ring to form the labyrinth seal, and is arranged at a machine housing end; the contact seal is formed by two dedicated shaft seal rings arranged in pair, and is arranged at a bearing chamber end; a grease filling pipe is arranged between the two dedicated shaft seal rings; and the a grease filling hole connected with the grease filling pipe is arranged in the bearing gland. The shaft sealing device of the horizontal scraper centrifuge can reliably seal feed liquid and gas at the machine housing end as well as gas and lubricating oil at the bearing chamber end, and further has greatly prolonged service life compared with the present shaft seal.

Description

The horizontal type scraper centrifuger shaft sealer
Technical field
The utility model relates to a kind of horizontal type scraper centrifuger shaft sealer.
Background technique
Usually only adopted contact seal or non-contact sealing between horizontal type scraper centrifuger casing and the bearing chamber; The former is owing to the poor sealing performance to material; Material particles is prone to get into sealing configuration and causes sealing configuration accelerated wear test or corrosion; Therefore working life is short; And the latter is poor to gas tightness, and ambient atmos gets into chassis end easily, and is higher and need then not reach requirement at the material that oxygen-free environment realize to separate to demand.
Summary of the invention
In view of this, the purpose of the utility model provides a kind of can be reliably the gas and the lubricant oil of the feed liquid of chassis end and gas, bearing chamber end the sealing, and working life long horizontal type scraper centrifuger shaft sealer.
For realizing above-mentioned purpose; The technological scheme that the utility model adopts is: a kind of horizontal type scraper centrifuger shaft sealer; Comprise non-contact sealing, contact seal, rotating shaft and bearing gland, said horizontal type scraper centrifuger shaft sealer is made up of the non-contact sealing and the contact seal that are arranged in the rotating shaft, and said non-contact sealing is made up of rotating ring and stationary ring; Form labyrinth seal, and be arranged at chassis end; Said contact seal is made up of two special axis seal rings of paired setting, and contact seal is arranged at the bearing chamber end, between two special axis seal rings the stuffing pipe is set, and the stuffing hole that connects the stuffing pipe is set on the described bearing gland.
The beneficial effect of the utility model is: the horizontal type scraper centrifuger shaft sealer of the utility model can be reliably seals the gas and the lubricant oil of the feed liquid of chassis end and gas, bearing chamber end, and working life, existing shaft sealing prolonged greatly.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
Fig. 1 is the horizontal type scraper centrifuger shaft sealer structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of horizontal type scraper centrifuger shaft sealer; Comprise non-contact sealing, contact seal, rotating shaft 1 and bearing gland 2, said horizontal type scraper centrifuger shaft sealer is made up of the non-contact sealing and the contact seal that are arranged in the rotating shaft 1, and said non-contact sealing is made up of rotating ring 3 and stationary ring 4; Form labyrinth seal, and be arranged at chassis end 7; Said contact seal is made up of two special axis seal rings 5 of paired setting, and contact seal is arranged between 8, two special axis seal rings 5 of bearing chamber end stuffing pipe 6 is set, and the stuffing hole 9 that connects stuffing pipe 6 is set on the described bearing gland 2.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
