Lime Feed Systems
Series 31-165 Digital Weighbelt Feeder
The Series 31-165 microprocessor controlled weighbelt feeder controls the feed rate of dry lime with an accuracy as low as 0.25% of set rate. Its accuracy and instantaneous response to feed rate changes and variations in lime density provide tight control of lime usages and minimize waste. The controller can provide information about lime application rate for record keeping or inventory control. The Series 31-165 weighbelt feeder is ideal for industrial and municipal water and wastewater treatment systems or for systems treating industrial process water.
KEY BENEFITS
• Accurate and reliable feeder operation
• Microprocessor controlled gravimetric feeding
• Accuracy of 1% of rate
• Simple, straight forward man-machine interface
• Easy to install and maintain
FEATURES
Microprocessor Controlled Gravimetric Feeding to 8,000 lb/hr or 133 ft3/hr
With gate adjustment and different gearboxes and driven sprockets, the feeder will provide a wide range of capacity selection and flexibility. Maximum rates cover virtually all water and wastewater chemical feed requirements.
Instant Response, Accuracy of 1% of Rate
The precision weigh-scale and microprocessor electronics provide exact control of lime addition in response to changing process requirements. Costly overfeeding is avoided.
Simple, Straightforward Man-Machine Interface
The feeder controls include a touch screen for entering commands and
parameters. Its menu driven software provides information regarding status, operational parameters, and alarm conditions. Alarm conditions
displayed include: low and high feedrate, low and high belt load, low and high belt speed, setpoint and fault condition.
Simple, Automatic Belt Tension and Tracking
Constant and uniform tensioning of the weighbelt is achieved by the use of counterweights acting on the movable front (discharge) roll. An adjustable manual tensioning roller includes a belt tracking guide which, in conjunction with the movable front roller, directs the belt along a straight path. Both of these mechanisms function together to provide accurate and reliable feeder operation.
Rugged Weighbar Weigh-Scale
The weigh-scale utilizes a sensitive, yet rugged, weighbar to transmit the belt load force directly to a precision load cell. The bar is designed for minimum surface area contact with the weighbelt to reduce belt drag and prevent the belt from sticking to the weigh-scale. It also provides easy access for inspection and cleaning.
Easy to Install and Maintain
All feeders are factory calibrated and tested prior to shipment. A simple field procedure confirms calibration after installation. The need for
calculations by the operator and repetitive adjustments are eliminated. The feeder housing is dust-tight. Side and top covers are gasketed and easily removed. The product zone is easily accessible and can be air-cleaned. Sealed bearings are used throughout. Six scrapers spaced on both sides of the belt and on the rollers keep the belt transport free of product build up. The belt transport system is cantilevered for easy belt removal without tools.
