As shown in fig. 1 to 6, the present application provides:

the utility model provides a desulfurization operating system band conveyer bearing roller, including steel axle 1 and nylon wheel 2, still include sealed bearing 3 and waterproof sealing washer 4, fixed slot 2a has all been seted up at the both ends of nylon wheel 2, fixed slot 2a is whole to be circularly, fixed slot 2a and the coaxial setting of nylon wheel 2, rotatable sealed bearing 3 that is provided with in the fixed slot 2a, sealed bearing 3 and the coaxial setting of nylon wheel 2, the one side that nylon wheel 2 was kept away from to sealed bearing 3 is provided with waterproof sealing washer 4, there is first axle clearance between sealed bearing 3 and the nylon wheel 2, there is the second axle clearance between sealed bearing 3 and the steel axle.

Based on the embodiment, the technical problem that this application wants to solve is because the thick liquid and the sparge water are more in the equipment operation leads to easily to enter into thick liquid or water in the belt bearing roller shaft gap, and the axle easily appears corroding after getting into or can not rotate along with the belt operation after getting into the thick liquid between axle and bearing roller, makes the friction wearing and tearing each other between belt and bearing roller, and the change frequency is higher. Therefore, the slurry firstly passes through the waterproof sealing ring 4 when moving to the end part of the carrier roller from the edge of the belt, thereby playing a certain protection role, the slurry permeates into the first shaft gap between the sealing bearing 3 and the nylon wheel 2 along with the use time, so that the sealing bearing 3 and the nylon wheel 2 can not rotate, at the moment, the nylon wheel 2 and the sealing bearing 3 rotate with the steel shaft 1 while keeping relatively fixed, the slurry permeates into the second shaft gap between the sealing bearing 3 and the steel shaft along with the use time, at the moment, the sealing bearing 3, the steel shaft and the nylon wheel 2 can not rotate, compared with the prior art, the steel shaft of the slurry transmission carrier roller has the advantages that the nylon wheel 2, the sealing bearing 3 and the waterproof sealing ring 4 are matched to ensure that the slurry can take a longer time to enable the steel shaft, the nylon wheel 2 and the sealing bearing 3 to rotate, the service cycle of the carrier roller is directly prolonged.

Further:

the annular groove 3a has been seted up on the one side that nylon wheel 2 was kept away from to sealed bearing 3, and the arc wall sets up with sealed bearing 3 is coaxial, and the external diameter of arc wall equals the internal diameter of waterproof sealing washer 4.

Based on the above embodiments, the technical problem that the present application intends to solve is that the slurry penetrates the first axial gap and then enters the second axial gap soon. For this reason, this application leaves earlier the back through thick liquid from first axle clearance and enters into annular groove 3a and piles up, pile up in annular groove 3a and during full back thick liquid could enter into the second axle clearance, compare in prior art, the sealed bearing 3 of this application plays the time that the extension thick liquid got into in the second axle clearance through seting up annular groove 3 a.

And further:

sealed bearing 3 keeps away from the one side central part of nylon wheel 2 and the tip of nylon wheel 2 and keeps flushing, and sealed bearing 3 keeps away from the one side edge part of nylon wheel 2 and is in inside fixed slot 2a, and the one side that sealed bearing 3 was kept away from to waterproof sealing ring 4 flushes with the tip of nylon wheel 2, and waterproof sealing ring 4's external diameter equals the diameter of fixed slot 2 a.

Based on the above embodiment, the technical problem that this application wants to solve is that waterproof sealing ring 4 easily receives the damage. For this reason, this application makes waterproof sealing ring 4 be in inside the nylon wheel 2 through the thickness of injecing sealed bearing 3, compares in prior art, and waterproof sealing ring 4 of this application guarantees that waterproof sealing ring 4 is in inside the nylon wheel 2 and receives the protection through the thickness of injecing sealed bearing 3 and waterproof sealing ring 4.

Further:

one end of the annular groove 3a, which is far away from the axis and the waterproof sealing ring 4, is set to be a cambered surface.

Based on the above embodiment, the technical problem that the present application intends to solve is that the slurry does not move on the annular groove 3a along the inner wall of the annular groove 3 a. For this reason, this application makes the thick liquid remove along with the cambered surface through setting up the cambered surface, compares in prior art, and sealed bearing 3 of this application makes the thick liquid can not break away from the inner wall arbitrary removal of ring channel 3a in ring channel 3a through being provided with the cambered surface.

Further:

a drainage shaft 3b is arranged in the annular groove 3a, the drainage shaft 3b extends towards the direction far away from the axis of the sealing bearing 3 along the axial direction of the sealing bearing 3, and the extending track of the drainage shaft 3b is in an arc shape which is matched with the position of the annular groove 3a far away from the waterproof sealing ring 4.

Based on the above embodiment, the technical problem that the present application intends to solve is that the slurry coming out of the first axial gap does not enter the annular groove 3 a. For this reason, the present application is guided into the annular groove 3a by contacting the guiding shaft 3b after the slurry comes out of the first axial gap, and the seal bearing 3 of the present application functions to guide the movement of the slurry by the guiding shaft 3b, compared to the prior art.

Further:

the number of the drainage shafts 3b is several, and all the drainage shafts 3b are uniformly distributed along the axis of the seal bearing 3.

Based on the above embodiment, the technical problem that the present application intends to solve is that the slurry overflows and accumulates in the annular groove 3a too much to affect the normal rotation of the sealed bearing 3. For this reason, this application makes thick liquid pile up respectively in these spaces through setting up a plurality of drainage axle 3b annular groove 3a etc. and divide into a plurality of space, compares in prior art, and the annular groove 3a of this application makes thick liquid evenly distributed in annular groove 3a through being provided with a plurality of drainage axle 3 b.

The above embodiments only represent one or several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention.
