A split filter

Abstract

The invention discloses a flow-dividing type filter which comprises a flow divider, a confluence component and an annular filter disc, wherein the flow divider and the confluence component are the same in structure and are symmetrically mounted and connected; each of the flow divider and the confluence component is composed of a total flow pipe section, a flow-dividing pipe section and a flange, which have an integrated structure; each flow-dividing pipe section has a circular platform structure; the small end surface of each flow-dividing pipe section is connected with the corresponding total flow pipe section while the periphery of the big end surface of each flow-dividing pipe section is connected with the corresponding flange; a total flow channel is arranged in each total flow pipe section; a flow-dividing cone and a plurality of flow-dividing channels are arranged in each flow-dividing pipe section; a filter disc embedding slot is formed in the big end surface of each flow-dividing pipe section; when the flow divider is connected with the confluence component, the filter disc embedding slot in the flow divider and the filter disc embedding slot in the confluence component form a filter disc mounting slot; the annular filter disc is mounted in the filter disc mounting slot. The flow-dividing type filter is reasonable in structure. The manner of flow dividing, filtering and confluence in sequence is adopted, so that the service life of the filter disc is greatly prolonged.
