Abstract
The invention relates to a mechanical sealing anti-twisting device, belonging to the technical field of water treatment equipment. The device is characterized by being composed of a fixed mantle and a movable mantle which are arranged at the sealing position of a fixed part and a rotatable part, wherein the fixed mantle is of a sleeve shape, one end of the fixed mantle is connected with the fixed part and the other end of the fixed mantle is provided with a notch; the rotatable part is fixedly connected with the movable mantle, the movable is composed of an inner ring sleeve and an outer ring sleeve which are located inside and outside the fixed mantle respectively; and the inner ring sleeve is an eccentric ring sleeve sleeved outside the rotatable part, the opening end of the outer ring sleeve is provided with a corresponding notch which can form a shearing blade together with the notch of the fixed mantle. According to the invention, the long-term confused problem that the rotation sealing position of a driving apparatus is twisted is well solved by virtue of an innovative theory and a reasonable structure, thereby ensuring the long-term stable operation property of the apparatuses.
Description
Technical field
The present invention relates to a kind of anti-wrap device, especially a kind of mechanical sealing anti-twisting device, belongs to water-treating equipment technical field.
Background technique
In water treatment technology facility, often use diving apparatus, as diving mixer, submersible water impeller, submersible aerator etc.The running shaft of these diving apparatuses adopts the anti-sealing of mechanical sealing element to enter in motor and mechanical transmission component conventionally.Due in water body, especially often contain the fibre object that is difficult to remove (as hair, send out, braid etc.) in sewage, when diving apparatus turns round in sewage, these fibre object can be wrapped on the mechanical sealing element of running shaft, if fibre object length is greater than the girth of mechanical sealing element, fibre object will twine more and more in mechanical seal, causes mechanical seal cisco unity malfunction even to damage.For a long time, how to prevent that it is troubling problem that diving apparatus is wound always.
Summary of the invention
The object of the invention is to: the realistic problem existing for above-mentioned diving apparatus, proposes a kind of mechanical sealing anti-twisting device that can properly settle winding problem, thereby guarantee the operation reliably and with long-term of diving apparatus.
In order to reach above object, mechanical sealing anti-twisting device of the present invention is made up of the quiet cover and the moving cover that are arranged on fixed block and revolving part sealing place; Described quiet cover is cannula-like, and one end and fixed block are connected, and the other end has notch; Described revolving part is connected with moving cover, and described moving cover is made up of the inner ring sleeve and the exterior ring cap that lay respectively at inside and outside described quiet cover; Described inner ring sleeve is the eccentric strap being enclosed within outside revolving part, and the opening end of described exterior ring cap has the respective slot that forms shear blade with described quiet cover notch.
When work, sound cover covers mechanical seal completely, and the sleeve pipe of quiet cover is inserted between the inside and outside ring set of moving cover, but leaves gap, does not interfere the rotation of moving cover.When equipment is dived beneath the water running, moving cover rotates with running shaft, when the fibre object in water is taken to mechanical seal place by current, the notch of driven cover exterior ring cap enters, and through the notch of quiet cover, to be cut off, shred by the shear blade of dynamic and static cover corresponding groove interruption-forming, under the centrifugal action then producing at the eccentric rotary of moving cover inner ring sleeve, the debris of cutting off will outwards be thrown away.
As can be seen here, the present invention is with the principle of innovation and rational structure, properly settled and made us for a long time the difficult problem that diving apparatus rotary seal place of puzzlement is wound, thereby guaranteed the ride quality of this kind equipment long-term stability.

Embodiment
Embodiment one
As depicted in figs. 1 and 2, the quiet cover 3 of---casing 4 and revolving part---rotating shaft 2 sealings place 6 by being arranged on fixed block and moving cover 5 form the mechanical sealing anti-twisting device of the present embodiment.As shown in Figure 3, its main body 3-1 is cannula-like to quiet cover 3, and one end is the flange 3-2 being connected with casing 4, and the other end has one group of axial kidney-shaped notch 3-3 spaced apart, makes tube wall be groove profile of tooth.Rotating shaft 2 is connected with moving cover 5.Moving cover 5 as shown in Figure 4, Figure 5, forms by laying respectively at quiet cover 3 inside and outside inner ring sleeve 5-1 and exterior ring cap 5-2 after assembling.Inner ring sleeve 5-1 is the eccentric strap being enclosed within outside rotating shaft 2, there is eccentric distance e with shaft axis, one end and exterior ring cap 5-2 are connected as a single entity by Transverse plane, the opening end of exterior ring cap 5-2 have with quiet cover 3 on notch 3-3 form the axial kidney-shaped notch 5-3 that one group of corresponding interval of shear blade distributes.1 is mounted in the impeller in rotating shaft 2.
Because mechanical seal place is completely by the quiet cover of mutual sleeve and moving covering, therefore can avoids long fibre thing and contact with mechanical seal, thereby prevent that long fibre thing is wound around in mechanical seal.The main body of quiet cover is inserted between moving cover exterior ring cap and inner ring sleeve, leaves movement clearance, does not interfere the rotation of moving cover.After equipment is dived beneath the water, mechanical seal and cover body are all immersed in water.When rotating shaft running, moving cover rotates thereupon, if when the fibre object in water is taken to mechanical seal place by current, driven cover outer layer sleeve kidney-shaped notch enters, through the kidney-shaped notch of quiet cover, be subject to dynamic and static cover and shear and cut off, shred, the centrifugal flow action that then rotation produces by moving cover internal layer eccentric bushing outwards throws away the debris of cutting off, and therefore can avoid fibre object to be wound around and the damage that causes.
In addition to the implementation, the present invention can also have other mode of executions.For example, the notch of exterior ring cap and inner ring sleeve respectively with the angle of axial formation opposite direction, thereby the scissor-shaped can form relative rotation time intersects cutting edge, is more conducive to cut staple; For another example, notch one lateral section that exterior ring cap and inner ring sleeve form shear blade has respectively leaning angle and the camber angle as scissors, thereby makes shear blade more sharp.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
