I. Auxiliary systems and automatic control
1. Filtration and circulation system
The high-precision bag filter (precision 5μm) is matched with a
centrifugal pump to achieve continuous purification and recycling
of degreasing liquid and pickling liquid.
2. Temperature control and monitoring
PLC controls temperature (±2℃) and processing time, and the touch
screen displays pH value, conductivity and other parameters in real
time, supporting data storage and traceability.
3. Environmental protection device
The acid mist collection tower (PP material) is combined with
alkali solution spray neutralization, VOC emission ≤50mg/m³, which
meets industrial environmental protection standards.
II. Examples of key process parameters
Parameters | Description |
Degreasing temperature | 40-60℃ (adjusted by oil type) |
Pickling time | 1-5 minutes (depending on the thickness of the oxide layer) |
Water washing conductivity | ≤50μS/cm (pure water standard) |
Trench material | PP/stainless steel (selected according to corrosiveness) |
I. Tank system
1. Degreasing tank
Using corrosion-resistant materials (PP, PVC or stainless steel), with built-in alkaline degreasing liquid (pH 9-12), the surface grease and pollutants of the workpiece are removed by spraying or soaking.
Some equipment integrates heating tubes (titanium or quartz materials), with a temperature control range of 30-60℃ and a processing time of 3-10 minutes.
2. Pickling tank
Equipped with nitric acid or mixed acid solution (such as H₂SO₄+H₃PO₄), it is used to remove metal oxide layers and microscopic impurities, and the tank body is designed with a leak-proof structure.
3. Water washing tank
Multi-stage countercurrent water washing unit, equipped with high-pressure spray (0.2-0.5MPa) or ultrasonic oscillation device to ensure that the residual amount of liquid is ≤50μS/cm.
II. Shell and support structure
1. Equipment shell
Enclosed tunnel structure, using stainless steel plate bending and
plug-in process, the weld is welded and closed to prevent liquid
leakage.
Door openings are set at both ends for workpieces to enter and
exit, and some models are equipped with transparent observation
windows.
2. Liquid storage tank and base frame The liquid storage tank
is located at the bottom of the spray section, integrated with the
shell, and has a built-in stainless steel protective net to prevent
foreign objects from falling.
The base frame is made of stainless steel square tube or
corrosion-resistant PP material, taking into account both strength
and chemical resistance.
3. Functional module
1. Filtration and circulation system Equipped with
high-precision bag filter (5μm level) and centrifugal pump to
achieve circulation purification of degreasing liquid and pickling
liquid.
The drainage system is graded for treatment, and acid and alkaline
wastewater are discharged independently to avoid cross
contamination.
2. Temperature control and exhaust system The electric
heating system integrates liquid level sensor and over-temperature
protection to ensure heating safety (accuracy ±2℃).
The exhaust system covers the main tank body and is equipped with
exhaust gas treatment equipment (such as alkali liquid spray tower)
to reduce VOC emissions.
3. Mechanical processing unit Sandblasting machine, polishing
machine or roller polishing machine can be selected to remove
severe oxide layer or surface roughening.
4. Auxiliary equipment
1. Spraying device
The high-pressure nozzle array covers the workpiece surface and is
suitable for cleaning complex structural parts.
Some equipment integrates a swing mechanism to enhance cleaning
uniformity.
2. Automation control module
PLC programming controls the process (such as time, temperature,
spray pressure), and the touch screen displays parameters in real
time and supports data traceability.
5. Examples of key components
Part name | Function description | Typical parameters/materials |
Degreasing tank heating tube | Maintain the activity of degreasing liquid | Titanium material, power 3-10kW |
Acid mist collection tower | Treat the volatile gas of pickling | PP material, neutralization efficiency ≥95% |
Ultrasonic vibration plate | Improve the cleanliness of water washing | Frequency 28-40kHz, power 1-5kW |
