Tote Cleaning System for Chemical Drums | Automated Cleaning and Filling

The tote cleaning system for chemical drums from Kehui is an automated, enclosed station designed to remove hazardous residues from 200L tight-head drums, open-top pails, and intermediate bulk containers. Unlike manual lancing, this tote cleaning system for chemical drums uses a programmable lift‑and‑rotate carriage combined with multiple fixed spray nozzles that deliver high‑impact jets at adjustable angles. The system supports both aqueous and solvent‑based cleaning fluids, with complete recirculation and filtration. All wetted parts are manufactured from PTFE‑lined steel or PVDF, ensuring compatibility with strong mineral acids, caustics, and aggressive organic solvents. Operators manage the cycle through a remote HMI, eliminating direct contact with toxic or corrosive residues. For facilities requiring validated chemical drum cleaning, the system logs pressure, temperature, and flow rate per batch.

Advantages

Product highlights of the tote cleaning system for chemical drums:

Robotic precision – 5‑axis arm reaches every interior contour, including ribbed walls and bottom sumps
Adaptive cleaning – changes spray angle (0°–90°) and pressure (20–400 bar) mid‑cycle per zone
Cuts cycle time by 40% compared to multi‑nozzle fixed systems
50% less chemical usage – targeted spray avoids wasted detergent on clean areas
One robot serves multiple drum positions – rail‑mounted arm travels between wash bays
Quick changeover – recipe selection by drum model loads new robot path in under 2 minutes

Core Technology

The core technology of the tote cleaning system for chemical drums:

The system integrates a 5‑degree‑of‑freedom electric robotic arm mounted on a linear rail. A 2D vision sensor scans the drum interior through the opening, generating a surface map. The PLC then calculates an optimal path, instructing the robot to move the nozzle at constant standoff distance (50–100 mm) while varying pressure according to soil level. Chemical drum cleaning efficiency comes from a three‑stage cycle: (1) cold low‑pressure water rinse to flush loose residues; (2) hot detergent wash (70°C, 250 bar) with the robot executing a spiral pattern from bottom to top; (3) heated air blow‑off through the same nozzle. Pressure sensors on the arm detect impact force and slow traverse speed where buildup is thicker. All robot trajectories are stored as recipes for up to 30 drum types.
