Abstract
A dustproof structure for a magnetic-fluid sealing device comprises a coaxial shell, magnetic-sealing parts, a magnetic transmission shaft and bearings, wherein the bearings are used for fixing the magnetic transmission shaft with the coaxial shell. The magnetic-sealing parts are arranged on two sides of the magnetic transmission shaft, the bearings are arranged at two ends of the magnetic-sealing parts, and areas enclosed by the coaxial shell, the bearings and the magnetic transmission shaft are dust intrusion areas. The magnetic-fluid sealing device further comprises dustproof covers arranged in the dust intrusion areas. The dustproof structure has the advantages that magnetic fluid is sealed and kept in vacuum, dust is effectively prevented from intruding the magnetic-fluid sealing device on the premise of no affection on operation of the magnetic fluid, and leak of equipment due to damages to the sealing device is avoided.
Description
Technical field
The utility model relates to the seal arrangement of a kind of engineering element or parts, relates to specifically a kind of dustproof construction for magnetic fluid seal device.
Background technique
In prior art, by magnetic field by magnetic fluid be fixed on running shaft surrounding, form the seal arrangement of on-mechanical contact, be widely used in semiconductor solar cell and LED equal vacuum manufacturing mechanism.For at partial vacuum manufacturing mechanism in running, in the region of running shaft and housing one side, can produce a large amount of dust, dust can be invaded in the magnetic fluid seal device in running, destroys the magnetic liquid of magnetic seal part, causes the leakage of equipment.
Model utility content
The purpose of this utility model is the dustproof construction for magnetic fluid seal device of invading magnetic fluid seal device in order to provide a kind of rational in infrastructure, effectively to intercept dust.
In order to reach the purpose of this utility model, technological scheme is as follows:
A kind of dustproof construction for magnetic fluid seal device, comprise: coaxial shell, magnetic seal parts, magnetic transmission axle and the bearing for fixed magnetic transmission shaft and coaxial shell, described magnetic seal parts are located at the both sides of magnetic transmission axle, described bearing is located at the two ends of magnetic seal parts, it is characterized in that: the region that described coaxial shell, bearing and magnetic transmission axle surround is dust invasion district, also comprise dust cover, described dust invasion is provided with dust cover in district.
As preferred technological scheme: described dust cover is S shape structure, described dust invasion is cooperatively interacted and is formed a labyrinth structure by one group of S shape dust cover in district.
The beneficial effects of the utility model are: this structure makes magnetic fluid seal keeping degree of vacuum, does not affect under the prerequisite of magnetic fluid running, effectively intercepts dust and invades magnetic fluid seal device, avoids device to damage, and causes the leakage of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-coaxial shell, 2-magnetic seal parts, 3-magnetic transmission axle, 4-bearing, 5-dust invasion district, 6-dust cover, 7-dust atmosphere.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
As shown in Figure 1, a kind of dustproof construction for magnetic fluid seal device, comprise: coaxial shell 1, magnetic seal parts 2, magnetic transmission axle 3 and the bearing 4 with coaxial shell for fixed magnetic transmission shaft 3, magnetic seal parts 2 are located at the both sides of magnetic transmission axle 3, bearing 4 is located at the two ends of magnetic seal parts 2, the region that coaxial shell 1, bearing 4 and magnetic transmission axle 3 surround is dust invasion district 5, also comprises dust cover 6, and dust invasion is provided with dust cover 6 in district 5.
Dust cover 6 is S shape structure, in dust invasion district 5, is cooperatively interacted and is formed a labyrinth structure by one group of S shape dust cover 6, and dust atmosphere 7 is effectively intercepted, and avoids dust invasion to destroy the magnetic liquid of hermetic unit, thereby causes equipment leakage
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, and all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
