40khz Ultrasonic Cleaning System Explosion Proof Automatic Ultrasonic Cleaner

Explosion-proof safety design for the whole system (Ex db IIC T4)
1. Triple guarantee of hardware explosion-proof
Cavity structure
▶ The cleaning tank and dewatering chamber are made of 316L stainless steel monolithically forged (thickness 8mm), and the inner wall is treated with EDM explosion-proof treatment (surface roughness Ra≤1.6μm) to prevent static build-up
▶ The viewing window is equipped with tempered explosion-proof glass (thickness 15mm) Conductive film coating (surface resistance ≤ 10Ω), light transmittance > 90% and burst resistance
electrical system
✔ Ultrasonic power supply with built-in explosion-proof transformer (IP66 protection class) with > 95% voltage fluctuation suppression rate
✔ All cables are armoured explosion-proof cables (according to IEC 60079-14) and sealed with explosion-proof glands at the joints (IP68 degree of protection)
Temperature control
▶ The heating module is equipped with a bimetal explosion-proof thermostat (accuracy ±1°C), and the overtemperature (>60°C) automatically cuts off the power supply and starts the nitrogen purging
▶ Real-time monitoring of solvent vapor concentration: built-in LEL sensor (detection accuracy of 1%), linkage of explosion-proof fan (air change of 2000m³/h) when the standard is exceeded
Fully automatic intelligent control system
1. Explosion-proof environment-specific interaction
Explosion-proof touch operation
▶ 10-inch explosion-proof touch screen (IP66 degree of protection), glove-enabled operation (thickness ≤ 3mm), process parameter adjustment accuracy of ±1%
▶ 50 sets of cleaning and dewatering formulas are preset, which can automatically match the ultrasonic power and dewatering time according to the workpiece material (metal/ceramic/plastic).
2. Safe traceability of the whole process
Encrypted data storage: Explosion-proof SPC report with ultrasonic power curve, vacuum level change, solvent concentration (5 year storage period) per batch
Docking with DCS system: Real-time upload of equipment status via Modbus RTU protocol, triggering workshop-level audible and visual alarms (response time<2 seconds)
Value-added service system
1. Special support for explosion-proof scenarios
Free explosion-proof environment adaptation test: customers provide working condition parameters, and issue equipment safety matching report (including gas concentration diffusion simulation) within 72 hours.
Customized explosion-proof certification: Assist customers to complete China explosion-proof certification (CCC Ex), North American explosion-proof certification (UL Class I Div 1), etc
2. Intelligent O&M assurance
Life-cycle management of explosion-proof components: regular inspection of the aging degree of explosion-proof seals (recommended replacement cycle of 1 year), insulation resistance of explosion-proof electrical appliances (early warning value<10MΩ)
24-hour explosion-proof emergency response: Reserve explosion-proof ultrasonic transducers, seals and other spare parts, and deliver them to the hazardous chemical production area within 48 hours
3. Environmental compliance support
Waste gas treatment solution: standard explosion-proof activated carbon adsorption box (treatment efficiency 90%), non-methane total hydrocarbon emission concentration < 50mg/m³ (better than GB 37822-2019)
Waste Sorting Collection: Explosion-proof solvent collection tanks (20L capacity) are available, in accordance with the Hazardous Chemistry
