General rotary-mounted filter provided with replaceable filter element

Abstract

The invention discloses a general rotary-mounted filter provided with a replaceable filter element. The filter comprises a casing and the filter element arranged in the casing, wherein a threaded connecting plate is arranged at the opening of the casing and adopts a disk structure corresponding to the casing opening shape, a butt-joint threaded through hole is formed in the middle of the threaded connecting plate and matched with an external thread of an oil outlet channel of a filter seat, and the filter seat and the casing can be closely connected; multiple oil inlet through holes are formed in the periphery of the threaded through hole of the threaded connecting plate, and oil entering a filter seat oil inlet pipe enters space between the casing and the filter element via the oil inlet through holes in the threaded connecting plate; multiple symmetric bulging teeth are arranged on the outer edge of the threaded connecting plate, grooves matched with the bulging teeth are formed in the opening of the casing, the circumferential dimension of the bulging teeth is smaller than that of the grooves, an elastic support piece is arranged at the bottom of the casing, and the threaded connecting plate is pressed and attached between the opening of the casing and an oil outlet of the filter element under the action of the elastic support piece. The problems that filter elements in existing filter casings cannot be replaced and the interchangeability of the filter casings produced by different manufacturers is poor are solved, replacement is simple, and operation is easy.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to an oil filter, in particular to a replaceable filter core and a filter housing assembly with a reusable housing. Background technique [0002] Existing commercially available diesel oil filter, it mainly has two kinds of forms, and a kind of is integral spin-on type, and a kind of is detachable replacement filter element type. [0003] The housing of the integral spin-on filter is provided with an oil inlet and an oil outlet, and communicates with an external oil inlet passage and an oil outlet passage through a filter seat. The filter element is set in the casing, and the casing and the filter element are integrated and cannot be disassembled separately. After the service life of the filter element expires, the filter element and the housing must be replaced as a whole, and the replaced filter housing can only be discarded. The advantage is that the filter seat and the shell are connect...
