1. Customer Background
A large-scale fine chemical enterprise specializes in the production of dye intermediates. During the production process, it generates a large amount of high-viscosity industrial sludge containing organic solvents. The enterprise’s original traditional filter press faced three major problems: the moisture content of the sludge after dewatering remained high (always exceeding 50%), the open filtration led to severe evaporation of organic solvents, which not only posed safety hazards but also brought risks of environmental penalties. Moreover, the manual unloading method resulted in low production efficiency and high labor intensity for the workers.
2. Solution
After on-site investigation and technical verification, we customized a 630 sealed hydraulic automatic filter press solution for this enterprise. This equipment adopts a sealed filter plate structure design, effectively eliminating the problem of solvent evaporation and fully meeting the strict explosion-proof requirements of the chemical industry. Its high-pressure hydraulic system can provide a working pressure of 1.6 MPa, and in combination with specially designed filter cloths and filter plates, it successfully controls the moisture content of the filter cake below 30%.
The equipment is equipped with an advanced PLC automatic control system, significantly reducing the need for manual intervention. Considering the corrosive properties of chemical materials, we have selected filter plates made of reinforced polypropylene (PP) to ensure the long-term stable operation of the equipment in environments with strong acids, strong alkalis, and organic solvents.
3. Implementation Results
After the equipment was put into operation, remarkable achievements were achieved: the moisture content of the filter cake decreased from the original 50%-55% to 28%-32%, and the dehydration efficiency increased by 40%; the processing time per batch was reduced from 4 hours to 2.5 hours, and the production capacity increased by 60%; the solvent evaporation loss decreased from 8% to less than 0.5%, fully meeting the environmental protection emission standards; the operation mode was reduced from requiring 2 workers per shift to fully achieving unmanned operation, and the labor cost was reduced by 100%.
4. Customer Feedback
“The 630 sealed filter press has completely resolved our production problems,” the production manager of the customer stated. “Not only does it achieve a dehydration effect far exceeding expectations, but more importantly, it enables clean production, eliminating the need to worry about environmental issues. The automation level is high, significantly reducing the labor intensity of the workers.” Currently, this equipment has been operating stably for 18 months and has become a key equipment on the customer’s production line.
5. Application Expansion
Based on this successful case, the chemical group has planned to introduce the same model of equipment to five other production bases. At the same time, this solution is also applicable to similar working conditions in the pharmaceutical, electroplating, and petrochemical industries, providing a reliable option for high-demand solid-liquid separation scenarios.
