EQUIPMENT FOR CLEANING SURFACE OF METAL FROM RUST, OIL AND DIRT

In the operation cleaning solutions are saturated with air bubbles. The formation of air bubbles is significantly reduced due to the ultrasonic cleaning. The exhaust gases are removed by distillation of the solution through the air separator, which greatly improves the process of ultrasonic cleaning.

The air separator is a set of outlets, it removes the smallest air bubbles, providing cleaning in vacuum environment. Thus, by addition of degreasing agents an effect of complex-shaped parts cleaning is achieved.

Finish parts cleaning and rinsing is made by products irrigation with steam coming from the steam generator. Thus the parts are subjected to heating with steam and immediately vacuum dried using a vacuum pump. Steam cleaning and vacuum drying systems are equipped with waste liquid recovery and distillation mechanism.

• High degree of cleaning agents solubility is achieved due to hydrocarbons heated up to 80-100℃
• Reducing of the time required for parts cleaning is achieved due to degreasing at high temperatures.
• Reducing of the time required for drying the parts is achieved through cleaning the parts at high temperature.
• Good solution filtration is achieved by reducing the surface tension of the liquid.
• Cleanliness of the surface after rinsing is achieved by irrigation and steam cleaning equipment.
• Cleaning and return to the system of used exhausts reduces washing solutions flow.

In standby mode, before washing the washing liquid is heated up to 80 ℃ temperature in vacuum environment. The washing liquid removes foreign bodies by filtration and cleans the equipment by gas regeneration.

After vacuum environment creating, the hydrocarbon solution is fed at a high temperature. Ultrasonic cleaning is carried out in vacuum environment. Removal of foreign bodies is achieved by filtration. Improving of degreasing characteristics is achieved through high temperature of the solution and high density of ultrasonic waves. Immediate dissolution of viscous oils and fats occurs.

After ultrasonic cleaning the used washing liquid is returned (distillated), and instead a large amount of purified steam solution is fed at high temperature, followed by rinsing. Efficiency of steam generation is 50% compared with the standard models, which maintains the output power.

All used steam is cleaned and recycled after parts processing. Residual droplets of the solution in the wash bath are dried by evaporation in vacuum environment. Once the equipment goes into standby mode recovered purified washing liquid is fed and the whole cycle repeats.

• Vacuum ultrasonic cleaning.
• Steam cleaning.
• vacuum drying.
• distillation and regeneration.

• 1. Vacuum ultrasonic cleaning
  • after de-aeration process the washing liquid in vacuum tank is changed. After that vacuum ultrasonic cleaning starts.
• 2. Switching between processes
  • cleaning fluid is automatically drained while the blank is installed in machine, and it switches the mode to the next.
• 3. Steam cleaning
  • cleaning solution used in vacuum ultrasonic cleaning can be completely removed by parts irrigation with hot steam supplied from the steam generator.
• 4. vacuum drying
  • high-speed vacuum drying is carried out in oxygen-free environments by use of self-generating heat and steam cleaning.
