This case study presents a successful implementation of a negative pressure pneumatic conveying system at a Shanghai-based daily chemical enterprise specializing in laundry detergent production. The client required a reliable, dust-free, and efficient solution for handling bulk raw materials such as sodium carbonate, sodium sulfate, zeolite, and surfactants. The chosen technology, provided by Shandong Headpowder Engineering Co., Ltd. (brand: headpowder), centered on the daily chemical powder vacuum conveying system, which operates under vacuum to transfer powders from storage to mixing or packaging stations without compromising product quality or worker safety. The project addressed critical challenges including material degradation, cross-contamination, and environmental dust emissions, delivering a fully automated, closed-loop solution.
The core of the installation is a vacuum suction system capable of drawing various detergent powder ingredients from multiple feed points. The system includes a positive displacement vacuum pump, cyclones, filter receivers, rotary valves, and a network of stainless steel pipelines. Raw materials are first unloaded from bulk bags or silos using a vacuum wand, then conveyed through the pipeline to a central receiving hopper. The negative pressure ensures minimal air velocity, reducing particle attrition and preserving the physical properties of the powders. This vacuum suction system is particularly suited for the daily chemical industry, where fine powders and hygroscopic materials must be handled gently. The conveying distance exceeded 80 meters horizontally and 15 meters vertically, with a throughput of up to 10 tons per hour for standard laundry detergent base powders.
The entire daily chemical raw material conveying engineering project was designed to meet stringent hygiene and safety standards. Key features include: (1) a fully enclosed pipeline with no leak points, preventing fugitive dust and product loss; (2) an automated control system using PLC with touchscreen HMI, allowing operators to monitor material flow, vacuum level, and filter cleaning cycles; (3) a modular design that enables future expansion without major downtime; (4) a low-energy vacuum generator with variable frequency drive, reducing power consumption by up to 30% compared to conventional systems. The headpowder team also integrated a metal detection and magnetic separation unit to ensure raw material purity before entering the production line. This comprehensive approach ensures that the vacuum conveying system not only transports materials but also contributes to overall product quality control.
Shandong Headpowder Engineering Co., Ltd. conducted a detailed site survey at the Shanghai facility to assess the existing layout, material characteristics, and production demands. The system was customized to handle multiple raw materials with different bulk densities (from 0.4 g/cm³ to 1.2 g/cm³) and particle sizes. The vacuum suction system was equipped with a multi-inlet manifold and automatic diverter valves, allowing the operator to select which material to convey without manual intervention. The filter receivers were designed with reverse-pulse jet cleaning, ensuring continuous operation even with sticky or moist powders. The project also included a dedicated silo system for storing finished laundry detergent powder, connected to the vacuum conveying line for final packaging. The entire installation was completed within 45 days, with minimal disruption to ongoing production.
After commissioning, the daily chemical powder vacuum conveying system delivered immediate improvements in several areas. The dust level in the production area was reduced by over 95%, creating a cleaner and safer working environment. The closed-loop design eliminated the need for manual handling of heavy bags, significantly reducing labor costs and physical strain on workers. The negative pressure system also prevented moisture absorption during transport, maintaining the free-flowing properties of the raw materials. The client reported a 20% increase in overall production efficiency due to faster material transfer and reduced cleaning downtime. Furthermore, the vacuum suction system enabled precise batch weighing by integrating with the existing dosing equipment, achieving an accuracy of ±0.5% for each ingredient. This level of consistency directly improved the quality of the final laundry detergent product.
The Shanghai daily chemical enterprise expressed high satisfaction with the performance and reliability of the headpowder system. The plant manager highlighted the ease of operation and the low maintenance requirements as key advantages. Shandong Headpowder Engineering Co., Ltd. provided comprehensive training for the on-site staff and a 24-month warranty on all major components. The company also offers remote monitoring and troubleshooting services via the PLC network, ensuring continuous uptime.
