Description
Technical field
The invention belongs to dust atmosphere process equipment field, relate to a kind of reduction dust access arrangement moving element inner, reduce the dust-proof sealing device of equipment operation wearing and tearing and danger.
Background technique
All there is granular material in a lot of processing environment, as aluminium powder etc., and particulate dust, particularly ultrafine dust can enter into equipment moving components interior through the gap between equipment moving parts.Dust in access arrangement not only can pollution lubricating oil and damage bearing, cause equipment attrition, even paralyse, and for some equipment of Flammable and Explosive Materials, if cleared up not in time, will gather at device interior, by equipment moving parts extruding and cause danger.Although the moving element of most equipment has seal arrangement, it is still difficult to avoid entering of dust, particularly for ultrafine dust, can not play good dust-proof effect.
By retrieving prior art, find to exist some for improving dust-proof effects of equipment and the technology that designs and special purpose device.Existing technology comprises sealing gland technology, if the patent No. is that CN200920111976 discloses a kind of dustproof sealing device for moving parts, it adopts installs at axle head the air chamber that has certain pressure, by the flowing of high-pressure air, the dust in cavity is removed, but it needs extra source of the gas, add energy consumption, and extra dust from flying can be caused at the gas that sealing area is revealed.Another kind of technology is the seal form by design specialized, and if the patent No. is a kind of drum rotating sealed dustproof structure that CN201320286844 announces, it adopts special sealing configuration, reduce entering of dust, but it has specificity, does not have versatility.
For prior art Problems existing and defect, the present invention devises a kind of dust-proof sealing device, it has independently sealing configuration, do not rely on the structural type of existing equipment, therefore there is versatility widely, the present invention introduces fluid sealing techniques in addition, can thoroughly solve entering of dust, solves the dust-proof incomplete problem of existing sealing technique.
Summary of the invention
In order to overcome the deficiencies in the prior art, improving dust atmosphere and dividing into standby reliability of operation, the invention provides a kind of a kind of dust-proof sealing device that can be applied to dust atmosphere.
A kind of dust-proof sealing device that the present invention relates to, is made up of liquid cup, outer fluid-tight, seal casinghousing, outer back-up ring, sealing transparent cover, interior fluid-tight, inner shield ring, plug.
Described liquid cup, it selects transparent material, and is provided with groove, in order to store the loss of sealing fluid and observation sealing fluid.
Described seal casinghousing, which is provided with collecting tank, in order to collect the sealing fluid revealed.
Described outer fluid-tight, outer back-up ring, it is arranged on seal casinghousing, in order to stop that extraneous dust contacts with sealing fluid.
Described sealing transparent cover, is provided with fluid-tight and back-up ring mounting groove.
Described interior fluid-tight, inner shield ring, it is arranged in sealing transparent cover, contacts with bearing support in order to baffle seal liquid.
Described plug, it is arranged on seal casinghousing, in order to emptying sealing fluid.
Compared with prior art, advantage of the present invention is: the double seal form adopting hydraulic seal and seal ring sealing, particularly adopt the mode of hydraulic seal, prevent entering of dust to greatest extent, and this device forms independently sealing configuration, do not affect the original seal form of equipment, there is versatility.The realization of this advantage relies on the technological innovation of following several respects: (1) seal casinghousing, outer fluid-tight, sealing transparent cover, interior fluid-tight constitute an independently seal chamber, and suitable sealing fluid can be filled in body of wall, thus the seal arrangement that formation one is complete; (2) sealing device introduce fluid sealing techniques, have simultaneously two seals with together with hydraulic seal, add the sealing of original bearing, form multi-sealed, thus avoid entering of dust to greatest extent; (3) this seal arrangement self forms complete sealing configuration, only need be installed on original bearing support during use, thus avoids the amendment to original sealing configuration, has versatility.

Embodiment
Below in conjunction with specification drawings and specific embodiments, the present invention will be further described.
As depicted in figs. 1 and 2, a kind of dust-proof sealing device of the present invention, comprises 2, liquid cup, and 3, outer fluid-tight, 4, seal casinghousing, 6, outer back-up ring, 7, sealing transparent cover, 8, interior fluid-tight, 9, inner shield ring and plug form.Outer fluid-tight is connected with seal casinghousing 4 with outer back-up ring; Interior fluid-tight is connected with sealing transparent cover 7 with inner shield ring; Sealing transparent cover 7 is connected with seal casinghousing 4 by screw; Liquid cup 2 is connected with seal casinghousing 4 filler opening, and plug is connected with seal casinghousing 4 oil outlet, thus forms whole seal arrangement.Mounting hole by seal casinghousing during use is connected with bearing support 1, and axle 5 is passed by the outer fluid-tight of dust-proof sealing device and the endoporus of interior fluid-tight.
The principle of a kind of dust-proof sealing device of the present invention is that outer fluid-tight forms first sealing; The liquid of filling in the sealed cavity that outer fluid-tight, interior fluid-tight, seal casinghousing 4 and axle 5 are formed, forms second sealing; Interior fluid-tight forms three seals.During use dust first stop by outer fluid-tight, if having a small amount of ultrafine dust through outer fluid-tight, then dust enters second sealing, and because second is sealed into liquid state, dust miscible will enter sealing fluid, thus block dust continue enter.Sealing fluid injects dust-proof sealing device by liquid cup, and can be observed the breakage of sealing fluid by liquid cup, supplements in time and changes.After using a period of time, by the fuel outlet of seal casinghousing 4, contaminated for inside sealing fluid can be discharged, and Seal cage be cleared up, sealing fluid of again annotating afterwards.If because outer fluid-tight wearing and tearing cause sealing fluid to reveal, observe finding by liquid cup, be provided with collecting tank on seal casinghousing 4 simultaneously, to collect the sealing fluid of leakage, preventing pollution material.Whole dust-proof sealing device is fixed on the bearing support of axle by screw, does not need to change original sealing configuration of axle, can realize reliably dust-proof, have good applicability.
