Filament dryer is a equipment commonly used in industrial production to remove water from materials to ensure the smooth progress of the production process and the quality of the final product. However, in the process of long-term use, it is easy to accumulate dirt and residue inside the dryer, which will not only affect its work efficiency, but also may shorten the service life of the equipment. Therefore, it is particularly important to clean the filament dryer regularly.
Preparation before cleaning
Before starting to clean the filament dryer, a series of preparations need to be made to ensure the safety and effectiveness of the cleaning process. First, disconnect the power supply of the device to ensure that the device stops running completely. Second, prepare the necessary cleaning tools and supplies, including brushes, vacuum cleaners, cleaning agents, protective gloves, glasses, etc. In addition, ensure that the working area is well ventilated to avoid harmful gases generated during the cleaning process.
Cleaning procedure
Initial cleaning: Use a brush and vacuum cleaner to remove dust and debris from the surface of the dryer. This step is mainly to remove the physical covering layer outside the equipment, such as oil dust, sand and so on.
Physical dirt removal: For physical dirt inside the equipment, such as solid particles and crystals, you can use high-pressure air or soft cloth to clean up. It should be noted that damage to the internal structure of the equipment should be avoided during the cleaning process.
Chemical dirt cleaning: chemical dirt mainly includes rust layer and corrosive substances. Diluted acid or lye can be used for cleaning. The commonly used acid is nitric acid (HNO3), which is mixed into a solution with a concentration of 1-2%, and the heating temperature is not more than 65℃ for washing; The commonly used lye has sodium hydroxide (NaOH), which is prepared into a solution of 0.5~1% concentration, and the same heating temperature does not exceed 65 ° C for washing. After cleaning, rinse the equipment thoroughly with water to ensure that there are no remaining chemicals.
Treatment of biological dirt: For algae, fungi and other biological dirt, you can use efficient and environmentally friendly cleaning agents for treatment. These cleaning agents usually contain wetting agents and penetrating agents, which can effectively remove the microbial coating without causing harm to the human body and equipment.
Treatment of mixed dirt: In actual use, the dirt on the surface of the dryer is often a mixture of various types. Therefore, when cleaning, you can choose the appropriate detergent and method according to the actual situation. For example, the use of efficient and environmentally friendly cleaning agents containing wetting agents and penetrating agents can simultaneously remove sediment such as scale, rust, oil scale and slime.
Disposal after cleaning
After the cleaning is complete, the equipment needs to be thoroughly inspected to ensure that there is no residual dirt and cleaning agent. Then, reconnect the power supply and start the device for testing to make sure it is working properly. In addition, in order to maintain the good condition of the equipment, it is recommended to carry out regular cleaning and maintenance, the specific frequency can be determined according to the use of the equipment and production requirements.
Total cleaning of filament dryers is a complex and important process that requires careful preparation and operation. Through the above steps, all kinds of dirt inside and outside the equipment can be effectively removed to ensure its normal operation and long-term service life. During the cleaning process, be sure to pay attention to safety, use appropriate protective equipment, and follow the relevant operating procedures. Regular cleaning and maintenance can not only improve production efficiency, but also reduce the maintenance cost of equipment, bringing greater economic benefits to enterprises.
