Product Specifications

Technical details and manufacturing context for Reagent Storage Hopper

Definition

The Reagent Storage Hopper is a component used within reagent injection systems in chemical manufacturing. It provides temporary storage capacity for liquid or powdered reagents, ensuring a consistent material flow to downstream injection points through controlled discharge mechanisms. The hopper is available in capacities from 50 to 500 liters, with custom sizes available upon request. It operates within a pressure range of 1.0 to 1.6 MPa. The operating temperature range is -40 to 85°C, with seals degrading above 85°C. Discharge accuracy is ±0.5%, ensuring consistent reagent dosing. The hopper is constructed from stainless steel 316L (ASTM A240) or food-grade polyethylene, with corrosion-resistant coatings available. Surface finish ranges from 0.4 to 0.8 μm Ra (ISO 4287) to prevent reagent adhesion. Ingress protection is rated IP54 to IP65 (IEC 60529), providing dust-tight and water-resistant operation. The power supply for control systems and sensors is 24 V DC ±10%. Weight ranges from 150 to 800 kg, depending on capacity and material thickness. Connection sizes are DN25 to DN80 with sanitary flange connections per DIN 11851. This hopper is designed for integration into larger injection systems, with controlled discharge achieved through gravity flow or mechanical assistance such as augers or vibrators. Flow rate is regulated by valves or gates to maintain consistent reagent supply. For selection, verify model-specific parameters, including capacity, pressure, temperature, and material compatibility, with the legal manufacturer or supplier. Confirm that the hopper meets applicable standards and is suitable for the intended reagent and process conditions. Regular maintenance includes checking seals, valves, and discharge mechanisms for wear or degradation. Failure indicators include inconsistent discharge, leaks, or seal deterioration. Always consult the manufacturer for detailed specifications and installation guidelines.

Working Principle

Reagents are loaded into the hopper where they are temporarily stored. Controlled discharge is achieved through gravity flow or mechanical assistance (such as augers or vibrators), with flow rate regulated by valves or gates to maintain consistent reagent supply to the injection system. The hopper's design ensures that material flow remains steady, preventing blockages or surges. The discharge accuracy of ±0.5% supports precise dosing. The hopper operates within specified pressure and temperature limits, and its materials and surface finish are chosen to resist corrosion and prevent reagent adhesion. The control system, powered by 24 V DC, monitors and adjusts discharge as needed. Proper operation requires that the hopper is installed correctly and that all seals and mechanical parts are maintained within their operational limits.
