Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.
Example (b):
as shown in fig. 1 and 2, the sand-proof sealing roller with a flushing nozzle of the present embodiment includes a supporting shaft 1, a bearing 2, a roller 3 and a sealing disk 4, wherein the roller 3 is radially positioned on the supporting shaft 1 by the bearings 2 installed at both ends thereof, and rolls by the bearings 2. The inner ring of the bearing 2 is axially positioned through a shaft shoulder or a positioning shaft sleeve of the supporting shaft 1, the outer ring of the bearing 2 is axially positioned through the roller 3, and the bearing 2 and the roller 3 are axially positioned mutually. The sealing disc 4 is arranged on the supporting shaft 1, the end faces of the two ends of the roller wheel 3 are blocked to lead to the opening of the bearing 2, and the sealing disc 4 is axially positioned through a shaft collar and a shaft shoulder or a positioning shaft sleeve of the supporting shaft 1.
A bent channel 5 which blocks the grinding material to decelerate and throws the grinding material out by the centrifugal force is arranged between the sealing disc 4 and the end surface of the roller 3. That is, the bending channel 5 itself not only forms a labyrinth seal joint, but also forms a plurality of rebounding deceleration surfaces to realize the deceleration of the abrasive materials such as steel sand and the like by the mutual staggering of a plurality of inclined surfaces (the inclined surfaces of the seal disk and the inclined surfaces on the two sides of the roller 3) on the bending channel 5, and the bearing 2 can be protected from the direct impact of the abrasive materials moving at high speed. The inclined form of the bevel from the inside to the outside makes it easier for the abrasive entering from the upper slot to be thrown out of the slot under the influence of centrifugal force.
The embodiment also adds the flushing nozzle 6, the flushing nozzle 6 is arranged above the end part of the roller 3, and the spraying direction of the flushing nozzle 6 points between the sealing disc 4 and the end surface of the roller 3 and is consistent with the direction of the outermost inner inclined surface of the bending channel 5. 3 during operation of running roller toward the passageway 5 of buckling water spray in order to increase abrasive flow nature, make the abrasive material that has got into the interior of passageway 5 of buckling throw away under the effect of centrifugal force more easily, reduced the abrasive material and piled up in the gap between bearing 2 and sealed dish 4 to prevent that bearing 2 and sealing member 7 from receiving wearing and tearing, thereby realize more effectual sand control effect, reduce the dead phenomenon of bearing 2 card, guarantee running roller 3's normal use, prolong its life.
In this embodiment, as shown in fig. 1 and 2, the sealing disc 4 is circumferentially provided with a first groove, the two end surfaces of the roller 3 are circumferentially provided with a second groove, and the circumferential diameters of the first groove and the second groove are different, so that the first groove and the second groove are alternately buckled to form a substantially S-shaped bent channel 5. And the first groove and the second groove are obliquely arranged, and the openings face the direction far away from the central line of the supporting shaft 1, so that the boundary of the bending channel 5 comprises a plurality of inclined planes which enable the abrasive to rebound and decelerate.
In this embodiment, as shown in FIG. 3, the chamfer comprises a chamfer on the sealing disk 4 that is aligned with the centerline I of the sealing disk 4 1 I 2 On OI 2 The included angle of the directions is alpha; the inclined plane also comprises an inclined plane on the roller 3, and the inclined plane and the center line I of the roller 3 3 I 4 At O 1 I 3 The included angle between the two angles is beta, and both the alpha angle and the beta angle are acute angles. Inclined plane and OI formed by circumferential outer wall of sealing disc 4 2 The included angle is an acute angle. When the roller 3 rotates, because the steel shots entering the gap between the sealing disc 4 and the roller 3 due to the existence of centrifugal force are easily thrown out, the quantity of the steel shots damaging the sealing element 7 or the bearing 2 is also reduced, and the occurrence of the phenomenon that the horizontal limiting roller 3 is stuck is effectively preventedAnd (4) generating.
As shown in fig. 2, the inclined surfaces on the seal disk 4 include a second inclined surface 41 and a fourth inclined surface 42 that constitute the side walls of the first groove; the inclined planes on the roller 3 comprise a first inclined plane 31 and a third inclined plane 32 which form the side wall of the second groove, and a fifth inclined plane 33 which is close to the central hole of the roller 3; the first inclined surface 31 is located outward relative to the third inclined surface 32, the second inclined surface 41 is located between the first inclined surface 31 and the third inclined surface 32, and the third inclined surface 32 and the fifth inclined surface 33 are located between the second inclined surface 41 and the fourth inclined surface 42; the spray direction of the flush head 6 coincides with the direction of the first inclined surface 31.
The above five inclined surfaces of the bending channel 5 constitute a plurality of rebound deceleration surfaces between the sealing disc 4 and the roller 3. When part of steel shots enter the gap between the sealing disc 4 and the roller 3, due to the existence of a plurality of rebounding surfaces, the steel shots rebound for many times through each inclined surface to reduce the turning speed, the hitting force is reduced, the running path is increased, and the quantity of the steel shots entering the gap between the sealing disc 4 and the roller 3 is reduced. And then the water spray nozzle 6 sprays water into the bent channel 5 between the sealing disc 4 and the end surface of the roller 3, so that the fluidity of the steel shot is increased, the direct damage of the steel shot to the sealing piece 7 or the bearing 2 is reduced, and the steel shot is prevented from being accumulated and agglomerated in the bent channel 5.
As shown in fig. 4, the rollers 3 of this embodiment are respectively mounted on the upper and lower surfaces of the metal strip (plate) to complete the conveying and cleaning of the metal strip (plate) at the upper and lower surfaces in the cleaning unit.
In the embodiment, the seal roller further comprises a sealing element 7 positioned between the bearing 2 and the seal disc 4, and the sealing element 7 can be a structure of installing a seal ring and the like on a shaft sleeve in a conventional way, as shown in fig. 1; the conventional sealing ring can be arranged, and meanwhile, a rib 71 is arranged on the shaft sleeve along the circumferential direction, as shown in fig. 2, 5 and 6, the end part of the roller 3 close to the central hole is provided with a scraping sheet 34 for scraping accumulated abrasive along the outer side of the rib 71. Scrape sand slice 34 accessible fastener and connect running roller 3, scrape sand slice 34 and when running roller 3 was rotatory along with the running roller, can scrape the accumulational abrasive material along the bead 71 outside and scatter, can make abrasive materials such as shot that have entered and exist between sealed dish 4 and the sealing washer more easily thrown away, be difficult for piling up. The section of the scraping sheet 34 in the radial direction is L-shaped, and 2 small holes are drilled on the scraping sheet 34 similar to a sector and used for being fixedly connected with the roller 3.
The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, the modifications and changes obtained without departing from the technical idea of the present invention should be regarded as the protection scope of the present invention.
