Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, and in particular to a centrifugal filter. Background Technology

[0002] From an industrial production perspective, many manufacturing processes require strict filtration of liquid or gaseous media. For example, in machining, if the cutting fluid contains impurities such as metal shavings and oil, it will accelerate tool wear and affect machining accuracy. In chemical production, particulate impurities in the reactants may poison the catalyst and reduce reaction efficiency. Traditional screen filtration or sedimentation filtration methods are prone to screen clogging when faced with high concentrations of impurities, requiring frequent shutdowns for cleaning, which seriously affects production continuity. Centrifugal filters, on the other hand, use centrifugal force to achieve solid-liquid separation, quickly separating impurities without the need for screens. They are especially suitable for media containing a large number of suspended particles, effectively avoiding clogging problems.

[0003] However, existing centrifugal filters are usually integrated units with an inseparable housing. If core components such as centrifugal rotors, guide vanes, and seals are worn, malfunction, or clogged, the entire device must be disassembled or even the housing must be damaged for repair. This process is complex and time-consuming. For example, when a centrifugal filter processes media containing high concentrations of impurities, these impurities may deposit on the inner wall of the housing. Since the integrated housing cannot be opened for cleaning, it can only be cleaned by high-pressure rinsing through the flushing port. This method is insufficient to completely remove stubborn dirt, and long-term accumulation can affect filtration efficiency.

[0004] Therefore, we provide a centrifugal filter to solve the above problems. Utility Model Content
