The 200L Iron Drum Internal and External Cleaning Equipment is primarily designed for efficient cleaning of the interior and exterior walls of standard 200L iron drums for recycling or reuse.
It uses the synergistic effect of high-pressure water or hot water and cleaning agents, combined with a multi-angle rotating nozzle and spray system, to quickly remove residue, oil stains, and debris from the drum's exterior. The working principle is as follows:
I. Overall Structural Components
Barrel Positioning System: Used to secure and clamp the drum (usually in an inverted position).
Inner Wall Cleaning System: Equipped with rotating nozzles/three-dimensional tank cleaning balls, these balls are inserted into the drum opening to clean the inside, achieving a 360° cleansing of the drum.
External Wall Cleaning System: Multiple sets of fan-shaped nozzles or high-pressure nozzles are deployed to thoroughly clean the drum's sides, bottom, lid, and other areas.
High-Pressure Pump Station: Provides cleaning fluid (fresh water/heated water/chemical solution) at pressures ranging from 3 to 100 MPa.
Control System: PLC control or manual buttons control the cleaning sequence, time, and pressure.
Wastewater Recovery System (Optional): Collects, filters, and recycles wastewater, conserving water.
II. Workflow Principle
1. Loading the drum (manual or automatic)
An operator or robotic arm places the drum upside down at the cleaning station.
A cylinder clamp or limiter secures the drum.
2. Internal cleaning begins.
The rotating nozzle is inserted into the barrel opening.
The nozzle rotates and sprays high-pressure water, covering all barrel surfaces.
The time is adjustable, typically 20 to 60 seconds.
3. External cleaning begins simultaneously or subsequently.
Multiple nozzles spray from multiple angles (top, side, and bottom).
Quickly remove external oil, dust, label residue, and other contaminants.
4. Drainage and drying (optional).
Automatic drainage upon completion.
Air knives or hot air blowers can be added for drying (especially common during subsequent filling).
5. Unloading the barrel (manual or automatic).
After completion, the barrel is manually removed or automatically pushed or dropped to the next station.
