Paint Manufacturer Utilizes Self-Cleaning Filter to Solve Throughput Problems
Flex Bon Paints of Ft. Myers, Florida experienced overflow and noise problems with the vibrating screen on its paint fill lines. A new in-line filter, installed to replace the vibrating screen, had its own set of problems. After seeing an ad for Ronningen-Petter Mechanically-Cleaned DCF filters, Flex Bon engineers contacted Ask Filter Man and got the help they needed. Flex Bon installed a Ronningen-Petter DCF-800 filter, forever solved the volume, and noise problems on its paint fill lines.
(PRWEB) February 9, 2006 -- Latex architectural paint manufacturer Flex Bon Paints used a vibrating screen for final filtering on its automatic and semiautomatic paint fill lines, prior to filling one and five gallon (4 and 19 liter) paint containers.
The flow rates on the lines ran as high as 80 gallons/min3 (18.2 m3h), but throughput on the vibrating screen was inadequate. The screen was too noisy, labor intensive and would overflow, because solids that collected on the screen had to be manually removed.
Flex Bon engineers decided to look for a quieter filtering system that could keep up with the fill lines and eliminate the overflow problems.
The in-line filter they selected seemed to fit the bill -- or so they thought. Soon after installation, they began experiencing problems, including seals that did not properly seal. The director of purchasing and plant operations at Flex Bon Paints said, "We were looking for an answer.
We saw an ad for Ronningen-Petter DCF filters and decided to get more information."
SOLUTION:
After consulting with Ronningen-Petter, Flex Bon installed a Mechanically-Cleaned DCF-800 filter with an electrical timer control that purges the collected solids at timed intervals.
The DCF-800 filter has a patented cleaning disc that moves up and down the filtering screen, scraping debris from the screen and collecting it in a chamber at the bottom of the filter.
The debris is periodically purged from the collection chamber by a discharge valve in a process that takes less than 7/10 of a second -- with no interruption
in production.
RESULTS:
The Ronningen-Petter Mechanically-Cleaned DCF-800 filter has no moving seals, so the sealing problems Flex Bon was experiencing with the in-line filter were eliminated.
Even better, the DCF-800 filter cleans and purges without halting production, resulting in a constant differential pressure and very high throughput levels on the paint fill line.
The director of purchasing and plant operations said, "We haven't found the upper limits of flow rates yet with the DCF. We feed our one-gallon and five-gallon lines at the same time and cannot starve them. It exceeded our expectations."
