Efficient Chinese herbal medicine washing machine is a key equipment in the production of traditional Chinese medicine, and its performance directly affects the cleanliness and production efficiency of medicinal materials. Standardized operation and scientific maintenance can not only ensure the stable operation of equipment, but also extend its service life and reduce the failure rate. This article combines industry practice to systematically sort out operational points and maintenance strategies, helping to improve production efficiency.
1、 Operation precautions
1. Check before startup
Equipment status confirmation: Check the equipment cleanliness certificate and integrity certificate to ensure smooth pipelines, correct valve positions, and normal power supply. If any abnormalities are found, they must be reported for repair immediately and operation with defects is prohibited.
Water source and circuit safety: Confirm that the inlet pressure is stable to avoid insufficient water pressure affecting the cleaning rate; Check the insulation resistance of the motor, and install moisture-proof devices during rainy season operations.
Fastener inspection: Focus on checking whether the screws and bolts are loose. Use a torque wrench to tighten them according to standards every month to prevent resonance or structural damage.
2. Standardization during operation
Water level control: When starting, first turn on the water inlet switch, and wait until the water level reaches 2/5 or 30cm of the washing medicine box volume before adding traditional Chinese medicine. The total amount of medicinal herbs and water should not exceed 4/5 or 45cm of the height of the container to prevent overflow or incomplete cleaning.
• Dynamic balance adjustment: after starting the equipment, adjust the water inlet and drainage to dynamic balance, and set the cleaning time strictly according to the process. To avoid overload operation, control the feed rate at 80% -90% of the nominal production capacity to prevent motor overheating or coil burnout.
• Safe operation: It is strictly prohibited to put objects into the detergent box; The retrieval of medicine should be carried out after the equipment has completely stopped. If there is severe vibration or abnormal noise during operation, the machine should be stopped immediately for troubleshooting.
3. Post shutdown processing
• Power outage and recording: After the work is completed, cut off the power, remove the pesticide residue, and fill in the production record and cleaning report.
Emergency situation handling: In case of water shortage and idling, immediately stop the machine and install an intelligent water level sensor for prevention; When the voltage is unstable, cut off the power for 5 minutes and then restore the power supply.
2、 Key points of maintenance and upkeep
1. Daily cleaning
• Residue removal: After each use, thoroughly remove the residue and use a high-pressure water gun to clean the inner wall, stirring blade, and filter screen of the tank to prevent residue from scaling. The alcohol extraction equipment needs to be cleaned by circulating ethanol or alkaline solution to remove oil and resin.
Surface cleaning: Use a fiber free cloth to wipe the surface of the equipment to ensure there are no stains or drug residues. The cleaning frequency can be flexibly adjusted according to the production batch or variety.
2. Regular maintenance
Lubrication management: Add food grade lubricating grease to mechanical components such as reducers and bearings every week; Apply rust proof oil to the chain and guide rail to prevent oxidation and jamming. Check the tightness of the belt every month, and adjust it to a width of less than 1.5cm when it is too loose to avoid affecting the speed.
Sealing component inspection: Regularly check whether the sealing ring is aging, replace hardened or cracked parts in a timely manner, and recommend using high-temperature resistant silicone or PTFE materials.
Electrical system maintenance: Clean the dust in the control cabinet and tighten the wiring terminals; Check the sensitivity of the temperature sensor and wipe the probe with alcohol when scaling.
3. Deep maintenance
Mechanical structure maintenance: monthly reinforcement of the belt wheel disc to prevent loosening and belt wear; Check the vibrator gear and lubricate it with butter every week.
Rust and corrosion prevention measures: Cover the equipment with protective covers after work is completed, and regularly apply lubricant to the valves and sealing rings to prevent them from getting stuck. Drain the accumulated water in the pipeline during winter to avoid freezing and cracking.
• Fault prevention: timely disconnect the damaged oscillator circuit when the ultrasonic system malfunctions; If the oscillator is damp, a megohmmeter should be used to test the insulation resistance. If it does not meet the standard, it should be baked to remove moisture.
3、 Common problem handling
Abnormal cleaning effect: If the material is not thoroughly cleaned, adjust the nozzle angle to 15 ° -30 ° and check if the high-pressure spray system is blocked.
Sealing ring leakage: Replace the cracked sealing ring or wrap the raw material tape around the spray gun thread to strengthen the seal.
Screen blockage: It is allowed to use wooden or bamboo strips to remove blockages, and violent repairs are prohibited to avoid equipment damage.
Conclusion
The standardized operation and scientific maintenance of efficient traditional Chinese medicine washing machines are the core of ensuring production safety and equipment lifespan. By strictly implementing startup inspection, operation monitoring, and shutdown cleaning, combined with daily cleaning, regular lubrication, and deep maintenance, the failure rate can be significantly reduced and equipment efficiency can be improved. Suggest developing a standardized maintenance checklist and strengthening operator training to achieve sustainable production benefits.
