Personnel protection  safety rules

• The dry ice pellets used by the machine may be harmful to health, and any contact must be avoided.
• When using dry ice blasting machine to clean carbon deposits from equipment, always wear protective goggles to prevent potential splashes from hitting your eyes. If you are hit, rinse the affected area with flowing water while
• keeping your eyes open. If symptoms persist, consult a doctor.
• Always wear protective gloves while working to avoid skin contact with dry ice pellets or contamination from dirt. If swallowed, seek medical advice immediately.
• Always ensure you have a stable footing to safely control equipment in case of emergencies.

CAUTIONS

Warning
Before using the instrument, please read this manual carefully for proper operation.

• If cleaning moving objects, firstly be sure to turn off the drive power of the objects to be cleaned.
• The temperature of dry ice is -78.5 degrees, and gloves must be worn for long-term contact with dry ice to prevent burns.
• The object to be cleaned and sprayed contains a lot of dust, so be sure to wear a protective mask.
• The spray head shall not against people, and the dry ice particles sprayed will hurt people.
• Cleaning with dry ice will produce certain noise, and it is necessary to wear noise-proof earmuffs during operation.
• It is forbidden to touch dry ice and the barrel of ice spraying gun.
• When adding dry ice, it must be kept clean and no other foreign objects fall into the equipment.
• This equipment uses solid CO2 particles, and ventilation must be ensured when operating dry ice cleaning.
• Before working, it is necessary to check whether goggles, earmuffs, work clothes and gloves are worn.
• Before each operation, first set the ice feeding speed to “0” and test whether there is condensed water sprayed from the nozzle.
• When the operation is not finished and suspended, please adjust the ice feeding speed to “0” , and then start the spray gun to spray for 30-50s to ensure that the residual ice in the feeding pipe is discharged and prevent ice blocking.
• To ensure that the compressed air pressure flow of the air source is sufficient, please choose the air source supply pipe with an outer diameter greater than DN20 and an air source pressure greater than 6bar, so as to achieve better cleaning effect.
• To prevent electric shock, please do not touch the working equipment in the wet place or operate the equipment in the rain.
• In case of equipment failure during operation, the power supply shall be disconnected immediately.

PRODUCT INTRODUCTION

Overview

• Dry ice cleaning uses compressed air as power to spray dry ice particles to the surface of the cleaned object at supersonic speed. However, it does not rely solely on the kinetic energy of dry ice particles, but uses the ultra-low temperature performance of dry ice to achieve the purpose of decontamination.
• Dry ice spraying medium – dry ice particles accelerate in the high-pressure air flow and impact the surface to be cleaned. The unique feature of dry ice cleaning is that the dry ice particles are vaporized at the moment during cleaning, and the momentum of dry ice disappears at the moment of impact. The heat exchange between dry ice particles and the cleaning surface occurs rapidly, resulting in the rapid sublimation of solid CO2 into gas, and the volume expansion of dry ice particles is nearly 800 times within a few thousandths of a second, thus causing “micro explosion” at the impact point. Due to the volatilization of CO2, no secondary waste is generated during the dry ice cleaning process, and only the dirt that needs to be cleaned.
• Any other use is considered beyond the intended purpose of the equipment and is prohibited.

Applicable industry field
Dry ice blasters are suitable for removing stuck and flaking formulations, silicone and rubber residues, oils, greases, turpentine, asphalt, dirt, inks, resins, adhesives, waxes and paints, chewing gum, and graffiti. It has been widely used in rubber, casting, automobile, marine, electric power, chemical, printing, plastic, food, pharmaceutical and aviation fields.

Function features

• Effective cleaning equipment for improving productivity.
  The main function of the dry ice blasters is to clean different equipment. On the one hand, dry ice cleaning can avoid the impact of shutdown on production, and at the same time, it can reduce the disassembly and damage of equipment, fundamentally protect the equipment and improve productivity.
• Avoid personal injury caused by hazardous substances.
  Cleaning with dry ice instead of toxic chemical to avoid long-term adhesion of undesirable substances to the equipment, affecting the overall operation and causing injury to personnel.
• Quickly remove all kinds of intractable dirt.
  The use of dry ice blaster can thoroughly remove the attached dirt and protect the equipment to avoid affecting the operation and use of the equipment during cleaning.

OPERATIONS INSTRUCTION

Equipment debugging

• Connect the host to the external air source and external power supply. Check whether the data of the air pressure indicator is normal and whether the power connection is normal (make sure the power supply is grounded normally).
• Make preparations for testing machine, including connecting the machine and accessories properly, checking whether the parts are loose, and cleaning the unnecessary items placed on the machine body or the work area.
• Turn on the power switch, then turn it to start mode first. And then press the start switch on the handle to run, adjust the dry ice volume from 0 to its maximum, check whether there is any abnormality, and then put dry ice materials into the machine for trial operation.

Adjusting the volume of dry ice blasting

• Add an appropriate volume of dry ice and cover the lid.
• According to the required cleaning degree, turn the dry ice volume adjusting controller to achieve the best effect as needed (it is recommended to set it to “5” first and adjust it according to the cleaning effect).
• If the barrel with smaller inner diameter is adopted, it is recommended to set it to “3” and then increase it as appropriate.
• After confirmation, align the spray gun with the parts to be cleaned, and press the start switch on the handle to enter the cleaning procedure.

Final work

• Turn the dry ice volume adjusting controller to “0” and start the spray gun to spray for 30-50s until no water is sprayed.
• The dry ice residue can be removed by extending the product’s spraying time, and manual cleaning is required if necessary.
• Turn off the power switch, disconnect the air source, and store the spray gun and accessories.

COMMON PROBLEMS AND TROUBLESHOOTING

Common faults
Analysis and treatment method:

• The ice is blocked in the ice hopper in the dry ice box.
• Stop the operation, open the cover, and check if there is excessive dry ice filled. If so, remove some dry ice, and then continue the operation.
• Check whether the vibration pump works. If not, contact the manufacturer for replacement.
• When filling dry ice into the funnel, it instantly removes the air inside the funnel and forms condensation blocks. It requires manual assistance using a steel rod at the center of the funnel to fill the dry ice.

Common faults
Analysis and treatment method:

• The dry ice pipe is vented but does not discharge ice (internal ice blockage).
• During the operation, intermittent use or intermittent shutdown can cause the residual dry ice and compressed air mixed in the ice outlet pipe, leading to icing. If this situation occurs: first adjust the ice output to 0, then turn on the spray gun switch and keep it running continuously for 3 minutes, then adjust the ice output to 20%-30%, and then observe the ice output effect.

Common faults
Analysis and treatment method:

• The dry ice pipe leaks ice and air.
• Check the air source to ensure that the compressed air supplied to the dry ice blaster is free of oil and water.
• The dry ice pipe has been used for a long time, and the dry ice has been rubbing against the pipe wall for a long time, resulting in the internal thinning. Contact the manufacturer for replace-ment.

Common faults
Analysis and treatment method:

• The cleaning effect is not perfect, carbon deposits and other intractable stains are not cleaned thoroughly.
• If the cleaning is not complete, first check whether the air pressure and flow of the external air source are insufficient. The working pressure of the dry ice machine is not less than 6bar and the flow rate is not less than 1m³/min.
• If the air supply pipe is too thin, too long, or directly connected to the quick interface, it will cause the pressure of the pipeline to drop too much. In this case, it is considered to directly connect the blaster to the main air supply pipe before operation.
