Abstract
A new sealing device for a rotary type device mainly contains a shell (2), a maze sealing plate (3), a support plate (4), a fish scale sealing plate (5), a holddown protection structure (6) and a liner (7). The utility model uses the maze type sealing and compound type sealing combined together in the radial direction, which not only resists most of the material and parts of the hot air flow, but also resists efficiently the fine material and hot air flow. The inner layer and external layer with a fish scale contact sealing is formed by hundreds of thin steel chip along the edge of the inner layer and external layer by mutually stacking and covering on the external surface of a rotation cylinder, which can produce a good adapting to the swing of the cylinder and imprecise geometric shape, as well as the excellent sealing function for a contact surface around the cylinder. The middle layer with fish scale type contact sealing is a heat insulation layer, which can protect a sealing chip of the external layer of the sealing device and can avoid the thermal radiation effect for the holddown protection device with a efficient working state for a long time.
Description
Technical field:
The utility model relates to the design and manufacturing technology field of building materials, metallurgy, chemical industry, industrial field high temperature rotating kind equipment auxiliary device such as coloured, particularly a kind of new type sealing device that is used to turn round kind equipment.
Background technique:
The revolution part of high temperature rotating kind equipment and the sealing between the fixed component, its basic demand is: 1) good seal performance.Negative pressure reaches 60 column in tube, and air sucks easily, and seal arrangement should be able to adapt to such pressure; 2) can adapt to the form error (ovality) of cylindrical shell, vertically reciprocal play in the coaxiality deviation of installation and the running; 3) light abrasion, maintenance and maintenance are convenient; 4) reliable in structure, simple as far as possible can high temperature resistant and corrosion.
At present, the seal arrangement that is used for this type of industry has many kinds, divide from sealing means labyrinth sealing is arranged, end face contact seal and radially contact seal etc.Labyrinth sealing is to allow air stream through the passage of bending, produces fluid resistance, and inleakage is reduced, thus labyrinth sealing only be applicable to gas pressure little, to the less demanding occasion of sealability.The end face contact seal is that loose collar is pressed on the end face of retaining ring by external force, but needs the thermal expansion amount and the shifting amount of digestion rotating cylinder, hour can select for use mini-plant bulk and shifting amount.Radially contact seal is radially to have surface of contact to prevent airflow between rotating cylinder and seal element, but needs the form error (ovality) of digestion rotating cylinder and the coaxiality deviation of installing, and influences sealing effect under the condition of limited seal element.
Summary of the invention:
For overcoming above-mentioned problems of the prior art, the purpose of this utility model provides a kind of new type sealing device that is used to turn round kind equipment, it effectively digests the various heat expansions of rotating cylinder, play, error, good sealing effect by the combination of labyrinth sealing and the contact seal of fish scale chip.
For achieving the above object, the utility model adopts following technological scheme:
Described a kind of new type sealing device that is used to turn round kind equipment; it is mainly by housing; the labyrinth seal plate; dunnage; the flap sealing plate; compressing protection structure and liner plate constitutes; housing one end is fixedly connected on the frame; and and cylindrical shell between certain interval is arranged; the labyrinth seal plate is positioned at housing and is fixedly welded on the cylindrical shell; fixing welding one dunnage on the housing other end; dunnage is fixedlyed connected with flap sealing plate one end; the flap sealing plate is by three layers of composition; internal layer and outer for cover the outer surface of rotary barrel along the mutual stack of the stalloy of up to a hundred of circumference; the mesosphere is a thermal-protective coating; the flap sealing plate top setting be equipped with and compress the protection structure; compressing the protection structure is made up of the wire rope that is fixed on the wire rope fixed base on the flap sealing plate and is used to adjust flap sealing plate tension force; the flap sealing plate the other end contacts with liner plate, and liner plate is fixedly connected on the cylindrical shell.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
Described a kind of new type sealing device that is used to turn round kind equipment, it is radially adopting one radial labyrinth formula sealing near the inner end, most of material and portion of hot air-flow are deadened, the outer end is radially three layers of fish scale chip contact seal, tiny material and hot air flow are effectively deadened, thereby form novel composite seal, its fish scale chip contact seal internal layer and outer for cover the outer surface of rotary barrel along the mutual stack of the stalloy of up to a hundred of circumference, can well good adaptability be arranged to the swing and the inaccurate geometrical shape of cylindrical shell, cylindrical shell circumferential contact face is played good seal action.Fish scale chip contact seal mesosphere is a thermal-protective coating, can protect the outer field diaphragm seal of seal arrangement and compress the few thermal radiation influence of protective gear, is in effective working state for a long time
