PURPOSE: A double filtering type strainer for removing foreign materials is provided to correspondingly fit and mount a screening lattice on an inner flow path instead of a structure for internally fastening the lattice with bots and so on, thereby easily fastening the lattice, preventing the lattice from being separated in the direction of the flow path by the unfastening of the bolts, and filtering the foreign materials in a fluid with a strainer on a pipeline without interrupting the flow of the fluid. CONSTITUTION: A double filtering type strainer for removing foreign materials includes a body part(10), a screening lattice(20), a micro-filter screen(30), and a safe filter screen(40). A flow path(12) is longitudinally formed inside the body part. A foreign material deposit part(14) is formed at the middle of the flow path. The screening lattice is coupled to one inner end of the body part. The micro-filter screen is integrated with one end of the screening lattice, and filters the foreign materials in a fluid flowing into the body part. The safe filter screen and the micro-filter screen form a double filtering structure. The safe filter screen separately connected to the front end of the micro-filter screen pre-filters the foreign materials in the fluid before passing the micro-filter screen. |
