AI Technical Summary

Technical Problem

Existing funnel repair technologies suffer from problems such as long construction cycles, difficulty in guaranteeing quality, and waste of resources. In particular, they are difficult to operate in narrow and irregular spaces, which makes the wear-resistant layer easy to be damaged and affects production safety.

Method used

Wear-resistant lining plates are fixed to the inner surface of the funnel wall to form a grouting cavity, and concrete slurry is injected into the cavity to form a concrete layer to repair the inside of the funnel.

Benefits of technology

It significantly shortens the construction cycle, ensures surface flatness, reduces the risk of material blockage, provides flexible and rapid repair methods, and allows for partial replacement of damaged parts, saving costs.

Abstract

This invention proposes a method for repairing the inside of a funnel and a funnel in general, belonging to the field of mineral storage equipment technology. To address the problem of long repair times in existing funnel repair methods, the method includes the following steps: Step 1, treating the inner surface of the funnel wall (1); Step 2, fixing a wear-resistant lining plate (3) to the inner surface of the funnel wall (1), forming a grouting cavity (4) between the wear-resistant lining plate (3) and the funnel wall (1); Step 3, injecting concrete slurry into the grouting cavity (4), forming a concrete layer (5). This method for repairing the inside of a funnel has advantages such as cost savings and flexible and rapid construction.
