Abstract

The present invention relates to a precision filter that removes impurities or foreign substances in various types of liquids so that only relatively clean liquids can be used. More specifically, in a liquid microfilter composed of a filtration tank having an inlet and a drain hole and having a filter cartridge inserted therein, and a cover body fastened to the front end of the filtration tank, locking protrusions are formed in all directions at the front end of a filter tank and locking grooves are formed in all directions inside the cover body to have fastening force by mutual insertion rotation. A separate watertight packing is inserted between the filter tank and the cover body. By configuring the upper and lower parts of the watertight packing to be tightly locked to the filter tank and the cover body, respectively, not only can a solid fastening state be maintained by simply rotating the cover body at a predetermined angle with respect to the filter tank, and the cover body can also be easily separated from the filter tank through reverse rotation. Thus, separation and fastening of the cover body can be done very easily. The watertight packing located between the filter tank and the cover body expands as the pressure inside the filter tank increases. Thus, adhesion is increased. Accordingly, it is possible to prevent the liquid inside from leaking out of the filter. Since the watertight packing is deformed in close contact only when the internal pressure is increased, deformation or change in physical properties due to local pressure hardly occurs, and the service life thereof can be further extended.

상기한 바와 같은 목적을 달성하기 위한 본 발명은, 입수구와 배수구가 형성된 여과탱크와 여과탱크의 상부에결합되는 커버체와 여과탱크의 내부에 안치되는 필터 카트리지와 상기 필터 카트리지를 고정하는 필터고정판으로 구성된 액체 정밀 여과기에 있어서, 상기 여과탱크의 상부 외측에는 반복의 잠금돌기를 사방으로 돌출 형성하고, 상기 커버체의 하부 내측에는 상기 잠금돌기와 대응하는 잠금홈이 사방으로 반복 형성된 잠금턱부를 돌출 형성하며, 상기 여과탱크와 커버체의 사이에는 별도의 수밀패킹이 삽입되도록 구성하여 이루어지는 것이다.The present invention for achieving the above object is a filter tank having an inlet and a drain port formed therein, a cover body coupled to the upper part of the filter tank, a filter cartridge seated in the filter tank, and a filter fixing plate for fixing the filter cartridge. In the configured liquid fine filter, a locking protrusion of repetition is formed to protrude in all directions on the outer side of the upper part of the filtration tank, and a locking protrusion in which a locking groove corresponding to the locking projection is repeatedly formed in all directions is formed on the lower inner side of the cover body, , is configured such that a separate watertight packing is inserted between the filtration tank and the cover body.

In addition, as described above, the watertight packing inserted between the filtration tank and the cover body is made of a material with excellent elasticity and chemical resistance such as silicone, and has a circular ring shape and a groove shape on the inner surface. It is made by forming an expansion groove of Here, the expansion groove portion serves to deform and expand the watertight packing in the up and down directions while the liquid introduced into the filtration tank flows into the expansion groove portion and the pressure acting on the liquid is transferred to the expansion groove portion. The locking groove portion is to be combined with the locking jaw and the fitting jaw formed in the cover body and the filtration tank, respectively, to complete a watertight structure with more adhesion to each other.
