This client is located in Monterrey, Mexico. It is a medium-sized lubricant recycling and re-refining enterprise. Every day, they process waste engine oil recovered from vehicles and industrial equipment. Through the silica gel adsorption process, impurities, gums and oxidation products in the oil are removed, and finally, reusable industrial lubricants are produced.
Facing challenges
In the original process, customers used simple bag-type filters for treatment, and the following problems existed:
After filtration, there are still fine white soil particles remaining in the oil, which affects the cleanliness of the finished product oil.
The filtration temperature is 90℃. The ordinary filter bags are not durable enough and often get damaged.
The batch processing capacity is 2000 liters. The time required for cleaning and discharging the old equipment each time is more than 2 hours.
There is no dedicated oil product transportation pump, resulting in low liquid output efficiency.
The customer explicitly stated that they needed a solid-liquid separation solution that is resistant to high temperatures, has good sealing performance, is easy to operate, and can simultaneously handle the process of feeding and liquid discharge.
Solution
We recommended and provided the XAY20/630-U type box-type filter press complete equipment to the customers, with the following configuration:
Model: 630×630mm box-type filter press, hydraulic pressing, manual pull plate, double dark liquid outlet
Filter chamber quantity: 24 middle plates + 2 head and tail plates, totaling 25 filter cloths (3927 material, resistant to 100℃)
Feed pressure: ≤ 0.6 MPa
Feed pump: KCB33.3 gear oil pump (1.5kW, three-phase 220V/60Hz)
Discharge pump: The second identical type gear oil pump, used for quickly extracting the filtrate oil.
Piping: Two sets of carbon steel pipes, respectively connecting the feed pump to the filter press and the outlet of the filter press to the finished product pump.
Color: Orange-red, meeting the safety color requirements of the customer’s factory.
Implementation effect
After the equipment was installed and debugged, the customer provided the following feedback:
Filtering accuracy has been significantly improved: The oil discharged is clear, with no visible white clay particles, meeting the requirements for re-refining feedstock.
Stable operation at high temperatures: Continuous filtration of 90℃ oil, with no deformation or leakage of the filter plate and filter cloth.
Batch processing time reduction: From filtration to discharge completion, it now takes only 50 minutes. Compared to the old equipment, the efficiency has increased by 60%.
Dual-pump system is convenient: The process of feeding and discharging liquid are clearly separated, saving the time for manual oil transfer.
Operation and maintenance are simple: The manual lever-pulling structure is clear. Factory workers can operate independently after just one hour of training.
Customer Review
“This box-type filter press has completely addressed our pain points in the white clay filtration process. The 3927 filter cloth has an excellent ability to retain white clay, and the counter-flow design keeps the workshop floor clean. The dual pumps configuration eliminates the need for additional transportation equipment and it can be plugged in and used immediately.”
Subsequent cooperation
Based on the success of this project, the client has ordered an additional unit of the same model for the second production line, and plans to expand the application scope from engine oil to hydraulic oil and industrial gear oil recovery filtration.
