Description

Technical Field

[0001] This utility model relates to the field of reaction vessel equipment technology, specifically to wear-resistant bushings for adhesive reaction vessels. Background Technology

[0002] Adhesive reaction vessels are key equipment in chemical production, used to mix and react various chemical raw materials to produce adhesives. Since adhesive raw materials or products often have certain corrosive or abrasive properties, long-term operation will cause serious wear to the inner wall of the reaction vessel. In order to protect the vessel body and extend its service life, a wear-resistant liner is usually installed on the inner wall of the reaction vessel.

[0003] Most wear-resistant bushings in the existing technology adopt an integral structure. This structure is relatively convenient for initial installation, but its fundamental drawback is that once any part of the bushing is damaged due to wear, the entire bushing must be replaced. This not only causes a huge waste of materials, but also the replacement process is complicated and requires a long downtime, significantly increasing the company's maintenance and production time costs. In addition, the way the bushing is fixed to the inner wall of the reactor is also crucial. During the reaction, the operation of the stirring device and the tumbling of materials will generate continuous impact and vibration on the bushing. If the bushing is not fixed firmly enough, it is easy to loosen or shift under long-term action. This displacement will not only aggravate the wear between the bushing and the reactor wall, but may also affect the stability of the reaction and pose a safety hazard.

[0004] Therefore, this utility model proposes a wear-resistant bushing for adhesive reaction vessels to overcome the shortcomings of the prior art. Utility Model Content
