AI Technical Summary

Technical Problem

Traditional steel drums are not corrosion resistant enough and are easily corroded by acid, alkali and salt media. The drum walls are prone to rust and perforation, have weak impact resistance, are easily deformed or cracked, and the internal media are prone to leakage.

Method used

It adopts a multi-layer composite structure, including a reinforced base, a corrosion-resistant layer, a barrier layer, and a sealing mechanism. The reinforced steel bars and steel rings enhance the impact resistance of the steel drum, the corrosion-resistant layer and the powder coating layer isolate corrosive media, the barrier layer prevents oxygen and organic solvents from penetrating, the polished layer improves corrosion resistance and easy cleaning, and the sealing ring and buckle achieve sealing and convenient handling.

Benefits of technology

It improves the corrosion resistance and impact resistance of steel drums, prevents deformation and media leakage, enhances the application range and aesthetics of steel drums, and achieves better sealing and convenience.

Abstract

This utility model discloses a multi-layer composite steel drum, relating to the field of steel drums. It includes a steel drum body, a reinforcing base fixedly connected to the bottom surface of the steel drum body, a reinforcing mechanism inside the steel drum body, an outer protective layer inside the steel drum body, and an inner protective layer inside the steel drum body. The reinforcing mechanism includes a steel plate layer with a cavity inside. Reinforcing steel bars arranged at equal intervals are fixedly connected inside the cavity. A reinforcing steel ring is located inside the cavity. The outer protective layer includes a corrosion-resistant layer, and the outer surface of the corrosion-resistant layer is coated with a powder coating. This utility model utilizes the combination of reinforcing steel bars and reinforcing steel rings to reinforce the steel drum body, increasing its impact resistance and preventing deformation. The combination of the corrosion-resistant layer and the powder coating layer isolates external corrosive media, preventing direct contact between the inner layers and the outer surface, further improving the hardness and aesthetics of the steel drum body surface.
