A kind of gluing process for cyclone overflow pipe

Abstract

The invention relates to a swirler overflow tube gluing technology. The technology comprises the following steps: step (1), a rubber long barrel is manufactured, wherein the length of the rubber long barrel is the sum of the length of a rubber layer, required to be glued, of the inner surface and the outer surface of a metal circular tube; step (2), the rubber long barrel is glued on the inner surface of the metal circular tube firstly, and the long barrel rubber extending out of the bottom of the metal circular tube is flanged outwards; step (3), after glue water is brushed on the outer surface of the metal circular tube, the long barrel rubber outwards flanged is dragged towards one end with a flange, and the rubber layer is glued on the outer surface of the metal circular tube. As the inner surface and the outer surface of the metal circular tube is glued integrally through the long barrel rubber, the bottom of the metal circular tube is without gluing gaps, so that the problem of glue failure is solved thoroughly. The problem of abrasion due to the glue failure when a swirler is in use is solved by changing the manufacturing technology, so that the economic benefit is obviously improved.

Description

technical field [0001] The invention relates to a gluing process for an overflow pipe of a cyclone, which belongs to the field of overflow pipe processing. Background technique [0002] The overflow pipe is a part of the cyclone, and its structure is a metal round pipe 1 with a connecting flange, which is lined with wear-resistant materials inside and outside, and rubber is a wear-resistant material. Our traditional bonding rubber sheet process is to first bond the inner surface of the overflow pipe with the rubber layer 3 of the inner cylinder, and then bond the rubber layer 2 of the outer cylinder. The bottom of the overflow pipe is sealed with the bottom end of the inner cylinder rubber layer 3, the outer cylinder rubber layer 2 and the metal circular pipe with the rubber plate of the head 4. However, the seal head 4 at the bottom is often glued during the use of the cyclone. Because there is a bonding gap 6, after a period of use, the bonding gap 6 at the head will be g...

AI Technical Summary

Problems solved by technology

However, the seal head 4 at the bottom is often glued during the use of the cyclone. Because there is a bonding gap 6, after a period of use, the bonding gap 6 at the head will be glued, causing the life of the overflow pipe to be greatly shortened.
