Food Industry: Perfect for the meticulous filtration of juices, wines, and more, enhancing product quality.
Other Industries: Adept at handling high-temperature wax removal, broadening its industrial application scope.
Work Principle
The operational heart of the cast iron pressure filter lies in its method: it fills the treatment liquid between the filter plates and cloth. Pressure compels the liquid through the filter cloth, leaving solid particles behind as a filter cake. Once filtration concludes, mechanical unloading seamlessly takes over to complete the process.
Maintenance and Care
Regular Inspection: Conduct thorough checks to ensure all connecting parts and seals are intact, effectively preventing any water leakage.
Cleaning: Promptly wash the filter cloth and plates post-use to eliminate any residue, maintaining optimal performance.
Lubrication: Consistently lubricate moving parts to guarantee smooth, uninterrupted operation.
Summary
With its formidable construction and superior performance, the cast iron pressure filter is an indispensable asset for industrial solid-liquid separation. Correct usage paired with diligent maintenance will notably enhance production efficiency while curbing operational costs.
