본 고안은 순환수에 혼입된 이물질을 여과하여 순환펌프의 성능을 향상시키고 그 수명을 길게 하기 위하 휠터를 내장시킨 경우, 이물질이 휠터 전면에 과다하게 누적되지 않고 밑으로 떨어져 고이도록 한 이물질 고임구조를 형성한 것에 관한 것이다.The present invention is to filter the foreign matter mixed in the circulating water to improve the performance of the circulation pump and to extend the life of the filter, the foreign matter holding structure so that the foreign matter does not accumulate excessively on the front of the filter, and fall down. It is about forming a.

휠터가 내장된 순환펌프는 배관내에 이물질이 많을 경우 이를 걸러주는 휠턴 전면에 과다하게 이물질이 흡착누적되므로서 펌프의 흡입구가 막히게 되어 펌프의 흡입성능이 급격히 저하되는 문제가 있었다.The circulator pump incorporating the filter has a problem that the suction port of the pump is clogged due to excessive accumulation of foreign matter on the front of the wheel to filter out a large amount of foreign matter in the pipe, thereby rapidly decreasing the suction performance of the pump.

본 고안은 이러한 문제를 해결하여 배관내의 이물질이 휠터전면에 흡착누적되지 않고 밑으로 떨어져 고이도록 하므로서 순환펌프의 성능저하 및 수명단축을 방지함에 그 목적이 있는 것으로, 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention solves this problem and prevents debris from accumulating on the front surface of the filter and prevents it from degrading and reducing the life of the circulation pump. Same as

모터케이싱(1)의 선단에 순환수유입관(2)과 배출관(3)를 가진 임펠러케이싱(4)이 결합되고, 순환수유입관(2)과 임펠러 케이싱(4)의 연통부(5)에 휠터망(6)를 설치한 것에 있어서, 휠터망(6)의 전면부가 되는 유입관(2)의 후단부위 직경(L)을 선단직경(L1)보다 크게 확장하여 이물질이 떨어져 고일 수 있는 공간(7)을 형성시킨 것을 특징으로 하는 이물질 고임구조를 가지 휠터 내장형 순환펌프인 것이다.An impeller casing 4 having a circulating water inlet pipe 2 and an outlet pipe 3 is coupled to the tip of the motor casing 1, and the filter is connected to the communication portion 5 of the circulating water inlet pipe 2 and the impeller casing 4. In the installation of the net (6), the rear end portion diameter (L) of the inlet pipe (2), which is the front portion of the filter network (6) is larger than the tip diameter (L1) space where foreign matters can fall and accumulate (7). It is a filter built-in circulating pump having a foreign matter pool structure, characterized in that formed).

본 고안의 실시에 있어서 제4도에 예시한 바와같이, 직경(L)이 가장 큰 부위가 되는 유입관(2)의 후단부에 나사(8a)(9a)에 의해 개폐가능한 상하 청소공(8)(9)을 형성하여 이 청소공(8)(9)을 형성하여 이 청소공(8)(9)를 통해 공간(7)내에 떨어져 고인 이물질을 제거할 수 있도록 구성할 수도 있는 것이다.As illustrated in FIG. 4 in the practice of the present invention, the upper and lower cleaning holes 8 which can be opened and closed by screws 8a and 9a at the rear end of the inflow pipe 2 which are the largest diameter L are the sites. (9) may be formed to form the cleaning holes (8) and (9) so as to be able to remove foreign matter accumulated in the space (7) through the cleaning holes (8) and (9).

첨부도면중 미설명부호 10은 패킹, 11은 임펠러, 12는 회전축을 나타내는 것이다.In the accompanying drawings, reference numeral 10 denotes a packing, 11 an impeller, and 12 a rotation axis.

본 고안은 순환수 유입관(2)의 선단직경(L1)보다 휠터망(6)의 전면부가 되는 유입관(2)의 후단직경(L)을 크게하여 휠터망(6) 전면에 충분한 공간(7)을 두어 흡인측의 유속을 낮춤으로서 이물질이 펌프흡인력에 의하여 휠터망(6)에 직접 흡착되지 않고 하단의 충분한 공간(7)내에 떨어져 고이게 되는 것이다. 따라서 휠터망(6)의 전면에 이물질이 흡착 누적되지 않으므로서 펌프의 흡입성능을 저하시키지 않게 되는 것이며, 그 사용수명도 길게 연장되는 효과를 제공한다.The present invention increases the rear end diameter (L) of the inlet pipe (2), which is the front part of the filter network (6) rather than the front end diameter (L1) of the circulating water inlet pipe (2) sufficient space in front of the filter network (6) By lowering the flow velocity on the suction side, the foreign matter is not directly adsorbed to the filter network 6 by the pump suction force and falls into a sufficient space 7 at the bottom. Therefore, foreign matter is not accumulated and adsorbed on the front surface of the filter network 6, so that the suction performance of the pump is not lowered, and the service life thereof is also extended.
