I. Analysis of Customer Pain Points and Challenges
A customer engaged in the processing of chemical raw materials needs to perform solid-liquid separation on a large amount of 10% concentration hydrochloric acid during the production process, in order to remove 2%-3% of the waste iron particles.
The production process faces three core challenges:
Strongly corrosive medium: 10% hydrochloric acid severely erodes ordinary metal equipment, resulting in shortened equipment lifespan, uncontrolled filtration accuracy, and increased risk of product contamination.
Large-scale continuous processing: The single processing capacity can reach up to 20m³. This requires extremely high standards for the processing efficiency, capacity and continuous operation stability of the equipment.
Stable solid content: It is necessary to ensure that the filtrate is highly clear, while the filter cake should have a low water content and be easy to discharge, in order to facilitate subsequent resource utilization and cost control.
II. Core Advantages of Customized Solutions
In response to these challenges, we have provided a comprehensive customized closed-box filter press solution:
1.Comprehensive corrosion-resistant design ensures the long-term stability of the equipment.
Core component material: All key components in direct contact with the medium are made of specially designed acid-resistant alloys or non-metallic materials, effectively eliminating the risk of corrosion.
Excellent sealing performance: The filter plate adopts a sealed box structure and is equipped with fluorine rubber sealing rings, effectively preventing the volatilization of hydrochloric acid, ensuring production safety and improving working conditions.
Long-term verification: After testing, it was found that this equipment operates stably under a 10% hydrochloric acid condition, significantly extending its service life and avoiding problems such as leakage and efficiency decline caused by corrosion.
2. Precise capacity matching with automation, enhancing operational efficiency
Large-capacity design: We have selected a model with a filter chamber volume of 600L, which perfectly meets the customer’s single-time processing volume requirement of 20m³ and is highly synchronized with the production rhythm.
Semi-automatic operation: The equipment is designed with semi-automation features, significantly reducing the intensity of manual operations and the frequency of intervention, ensuring the continuity and stability of the production process.
3. Outstanding separation effect, achieving a win-win situation for both economy and environmental protection
High precision filtration: Considering the characteristics of scrap iron particles, a special high-precision filter cloth was selected, combined with the pressing advantages of the box-type filter press, ensuring extremely high clarity of the filtrate.
Solid waste resource utilization: The filter cake formed after filtration has a low moisture content and is easy to discharge. This not only reduces the cost of solid waste treatment but also enables the recycling and reuse of waste iron particles, aligning with the concepts of circular economy and green production.
III. Summary and Outlook
The key to the success of this project lies in deeply understanding the individualized needs of the customers and providing a complete chain of customized solutions ranging from anti-corrosion materials, structural design to filtration processes. It not only solved the current production problems of the customers, but also brought additional economic and environmental benefits through resource recycling.
In the future, we will continue to be driven by technological innovation, focusing on various challenging solid-liquid separation scenarios. We will provide global customers with more professional and efficient personalized solutions, work together to create value, and achieve sustainable development.
