Drum and IBC Washers – Rotajet Manufacturing

Batch Washing Machines

Rotajet manufacture a range of batch 200 litre drum washing machines for use with water based

detergents. The machines are available with single stage wash or multiply stages to include rinse and

DI rinse steam extraction and dry, depending on the application. The drums are processed in a fully

enclosed cabinet to minimize health and safety issues, this also allows any fumes produced in the

cleaning process to be extracted and treated if required.

• The Rotajet D60dw will process 4x200 litre drums (open or closed top) per batch

• The Rotajet D40dw will process 1x200 litre drums (open or closed top) per batch The

machines require heating to achieve optimum cycle times, this can be done via. gas, oil,

steam or electric heating.

Rotajet manufacture a range of aqueous and non-flammable solvents for use in the machines

depending on the type of material that contaminates the drums to be cleaned. The list is shown

below:



Continuous Drum Washing Machines

For large numbers of drums, Rotajet manufacture the DW series of continuous tunnel type drum

washers, these machines can be manufactured with single or multiply stages depending on level of

cleanliness required. The machines are available as either single track tunnel wash or 4 track tunnel

washer.

The single track machine is the DW200 Series

The multi track machine it the DTW40

Manufacturing Process and Standards

Rotajet facilities in operate under stringent Health and Safety requirements with fully trained and

certified craftsmen. The system has been out together in compliance with the Industry standards as

follows:

EN602040-1 - Safety of machinery. Electrical equipment of machines. General requirements

EN349 - Minimum gaps to avoid crushing of parts of the human body

EN ISO 13857 - Safety distances to prevent hazard zones being reached by upper and lower limbs

EN953 – Machine Guarding

EN60204 - General principles for design

The details of each standard are available in the literature. In general terms, the manufacturing

process follows stringent procedures to ensure that the machines are fabricated using the specified

materials, specified standards and operate safely.



Operating Manual

The Plastic Drum Washer consists of a two stage wash machine designed to wash and rinse

contaminated closed and open top drums. The drums are manually loaded into the machine at high

level, once loaded the machine will index the drum through a series of stages identified below.

The wash and rinse solution re-circulates optimising water usage, the machine is also fitted with

sample points allowing the solution to be inspected at regular intervals.

Three control panels are located on the machine Main control panel, Pneumatic control panel and

Remote operating panel. The remote control panel is located on the loading platform allowing the

operator to have full control of the machine from the main operation area. This includes a remote

track reset button which has to be pressed after each drum has been loaded.



Initial Checks Prior To Starting Drum Wash Machine

✓ Ensure sump solution is at the correct level

✓ Ensure the sump chemical solution is correct.

✓ Check filter baskets

✓ Ensure the oil lubricator is at the correct level

✓ Ensure there are no obstructions on the machine

✓ Ensure there are no obstructions on the conveyor

Start up process

1) Turn ON the machine isolator.

2) Ensure the safety light is illuminated.

3) Ensure the ready light is illuminated.

Note: The machine will only stat if the Ready light is illuminated

4) Press the start button.

5) Open the machine loading gate

6) Load a drum in to position

7) Close the machine loading gate

8) Press the local Drum Loading Button on the remote control panel.



Machine Start up Sequence

1) Loading track will raise.

2) Loading track will move forward.

3) Loading track will lower.

4) Loading track will retract to its home position.

5) The cycle will start for a set period of time, during which the next drum is to be loaded, this

is identified by the loading light located on the remote control panel. To load a drum repeat

the process from step 5 downwards

6) If a new drum is not loaded the machine will continue the above steps moving the loaded

drums through the machine.

7) The once a drum reaches the last station it is deposited onto the conveyor, the conveyor is

programmed to move the drum away once the loading track as returned to its home

position.

Stopping the Machine

A Stop button is located on the control panel and remote control panel, by pressing the relevant

stop button the machine will come to a controlled stop.

Emergency-Stop Circuit

Emergency stop buttons are located on the control panel and various location around the machine.

If any of the E-stop buttons are pressed the machine will stop due to the mains power being

isolated. To reset the system, ensure all the E-Stop buttons are in the out position and press the

reset button on the front of control panel 1. When an E-Stop Button is pressed a fault code will

appear on the digital control panel



Reset after the machine has stopped

The machine can be stopped at any point during its process although you can only restart the

machine when every moving part is in its home position. To do this press the system home button at

the front of the main control panel, once this button has been pressed it will allow any load drums to

remain in the correct position and return to the machine home position.

Routine Maintenance Instructions

✓ Ensure sump solution is at the correct level

✓ Ensure the sump chemical solution is correct.

✓ Check filter baskets

✓ Ensure the oil lubricator is at the correct level

✓ Ensure there are no obstructions on the machine

✓ Ensure there are no obstruction on the conveyor

Before Start up each day - Customer

1. Ensure sump solution is at the correct level - Remove the filter basket lids and visually check to

ensure the solution level is correct.

2. Ensure the sump chemical solution strength is correct - Ref to chemical supplier for further

details

3. Check filter baskets - Remove the filter basket in both the wash and rinse tanks and clean

accordingly.

4. Ensure the oil lubricator is at the correct level - Visually check to ensure the oil level in the

pneumatic oil lubricator is correct.

5. Ensure there are no obstructions inside the machine - Visually check inside the machine to

ensure there are no obstructions which could affect the machine operation.

6. Ensure there are no obstructions on the conveyor - Visually check to ensure there are no

obstructions on the conveyor belt

7. Ensure the conveyor is aligned correctly - Visually check to ensure the conveyor chain is aligned

correctly.

The above routine maintenance programme has been calculated on an 8 hour, 5 days a week shift,

any additional working will require the appropriate increase in the programme. All maintenance

work is to be logged in a maintenance schedule book, Rotajet Systems Ltd might request to review

the log during a call out or routine machine service.
