1. Preparation before cleaning
1. Stop and cool
Before cleaning, be sure to stop the equipment and wait for it to cool completely. Avoid cleaning at high temperatures to prevent burns.
2. Cut off the power supply
Cut off the power supply of the equipment to ensure that the electrical system is in a safe state to avoid electric shock accidents.
3. Prepare cleaning tools
Prepare appropriate cleaning tools, such as brushes, scrapers, detergents, rags, etc. Choose the appropriate detergent according to the material and cleaning requirements of the equipment.
4. Wear protective equipment
Operators need to wear appropriate protective equipment, such as gloves, goggles, masks, etc. to prevent injury during cleaning.
2. Precautions during cleaning
1. Avoid using corrosive detergents
Do not use strong acids, alkalis or other corrosive detergents to avoid damaging the metal parts and seals of the equipment. It is recommended to use neutral detergents or special industrial detergents.
2. Clean key parts
Blades and heating surfaces: Focus on cleaning the surfaces of the blades and heating elements to remove possible scaling and residual materials. Scaling will affect the heat transfer efficiency and reduce the drying effect.
Internal pipeline: clean the feed port, discharge port and internal pipeline to prevent material accumulation or blockage.
Seals: check and clean seals such as rotary joints and valves to ensure good sealing performance.
3. Avoid damage to equipment parts
When cleaning, avoid using hard objects to scrape the surface of the equipment, especially heating elements and seals. If thicker scale needs to be removed, it can be gently scraped with a soft brush or scraper.
4. Clean up the accumulation and blockage
Regularly clean the accumulation and blockage inside the equipment to ensure that the material can flow smoothly. For parts that are difficult to clean, you can use a high-pressure water gun or steam to rinse, but pay attention to the control of water pressure and temperature.
5. Check the status of the equipment
During the cleaning process, carefully check the key components of the equipment, such as blades, bearings, heating elements, etc., and replace or repair the worn or damaged parts in time.
III. Post-cleaning treatment
1. Drying equipment
After cleaning, make sure that the equipment is completely dry inside and outside. You can wipe it with a clean rag, or turn on the equipment at a low speed for a period of time to remove residual moisture.
2. Relubrication
After cleaning, refill the transmission parts of the equipment (such as bearings and gears) with lubricating oil to ensure good lubrication.
3. Check the sealing
Reinstall the seals of the equipment and check the sealing performance to ensure no leakage.
4. Record the cleaning situation
Record the time, content, problems found and treatment measures of the cleaning in detail in the equipment maintenance log for future reference.
IV. Other precautions
1. Regular cleaning
Develop a reasonable cleaning cycle based on the frequency of use of the equipment and the characteristics of the materials. Generally speaking, it is recommended to perform a simple cleaning once a week and a comprehensive cleaning once a month.
2. Avoid excessive cleaning
Do not use excessive force when cleaning to avoid unnecessary wear and tear on the equipment. Especially for heating elements, excessive cleaning may cause damage to them.
3. Safety first
Always pay attention to safety during cleaning, avoid cleaning while the equipment is running, and prevent accidents.
