Based on the above situation, there is a need to develop a high-efficiency and programmable rotary sealing structure, which is composed of a common sealing device and a rotating device such as a hinge, and has the same appearance and effect as a fixed sealing device during normal production. When the equipment needs to be overhauled, the sealing device only needs to be rotated to the side through the hinge, and the sealing device is rotated back to the working position after the overhaul is finished.

In the prior art, two sealing channels are hinged, but in the rotating process, equipment connected with one sealing channel is easy to change and damage the hinge vertically due to uneven bottom surface, and if the sealing channels and the equipment are also changed into detachable connection, the amount of dust leakage in operation is increased, and the maintenance cost is also increased.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a not enough to prior art, the utility model provides a rotary seal structure has solved the problem that traditional articulated formula seal channel was easy to be broken with the hinge perpendicular when rotating equipment.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a rotary sealing structure comprises dust channels, wherein each dust channel comprises a channel body and flanges, the number of the dust channels is two, the two dust channels are symmetrically arranged, and the two dust channels are hinged to each other at the flanges;

the bottom of one of the two dust channels is connected with a base through a telescopic rod.

Preferably, the flange is provided with a mounting hole.

Preferably, the gap between the flange and the channel body is a filling groove.

Preferably, a sealing member is arranged in the filling groove.

Preferably, the bottom of the base is provided with a universal wheel set.

Preferably, the channel body is provided with a peeping window.

(III) advantageous effects

The utility model provides a rotary seal structure. The method has the following beneficial effects:

this rotary seal structure adopts articulated form between with two dust passageways, also is used for equipment fixing's base in dust passageway below fixed connection simultaneously, when needs are overhauld, only need rotate a certain dust passageway together with equipment can, avoided pulling bad hinge because equipment rotates.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution: a rotary sealing structure comprises a dust channel 1, wherein the dust channel 1 comprises a channel body 11 and flanges 12, the number of the dust channels 1 is two, the two dust channels are symmetrically arranged, and the two dust channels 1 are hinged with each other at the flanges 12;

the bottom of left dust passageway 1 is connected with base 3 through telescopic link 2, be provided with mounting hole 13 on flange 12, two dust passageways 1 can be fixed through bolt and mounting hole 13, the clearance between flange 12 and the passageway body 11 is filling groove 14, be provided with the sealing member in the filling groove 14, the leakproofness that seal structure can be dismantled in the increase, universal wheelset 4 is installed to base 3's bottom, be provided with peep hole 15 on the passageway body 11, left dust passageway 1's export is connected with equipment B, right side dust passageway 1's import is connected with equipment A, equipment B sets up on base 3.

In normal operation, as shown in fig. 6, bolts are arranged on the mounting holes 13 to tightly attach the flanges 12 of the two dust channels 1 together, meanwhile, a sealing element is arranged in the filling groove 14 to further improve the sealing property, and the observation window 15 arranged on the dust channel 1 is also convenient for observing the state of dust in operation;

if the dust channel needs to be disassembled for maintenance, the bolt is arranged on the mounting hole 13, the left dust channel 1 is rotated after being disassembled, and the whole body (such as fig. 7 and 8) formed by the equipment B, the base 3 and the telescopic rod 2 is formed, and then the dust channel can be maintained.

In conclusion, this rotary seal structure adopts articulated form between with two dust passageways, also is used for equipment fixing's base in dust passageway below fixed connection simultaneously, when needing to overhaul, only need rotate a certain dust passageway together with equipment can, avoided because equipment rotates and to draw bad hinge.
