Description

진공 강자흡식 펌프{Vacuum self-priming pump}Vacuum self-priming pump {Vacuum self-priming pump}

본 발명은 물이나 고농도 및 고점성을 갖는 액체를 진공 흡입하여 펌핑하는 진공 흡입 펌프에 관한 것으로, 공기와 물을 함께 흡입하여 펌핑하므로 잔여량이 없을 뿐만아니라 양방향으로 펌핑이 가능하고 흡입되는 찌꺼기를 잘게 절단시켜 펌핑하는 진공 강자흡식 펌프에 관한 것이다.The present invention relates to a vacuum suction pump that pumps water or a liquid having high concentration and high viscosity by vacuum suction, and pumps by suctioning air and water together, so that there is no residual amount and pumping in both directions is possible, and finely sucked residue It relates to a vacuum ferromagnetic pump for cutting and pumping.

물이나 점성을 갖는 액체를 펌핑하는 종래의 펌프 방식은 후드밸브가 열리고 닫힘에 따라 흡입물을 펌핑하는 방식과 또는 방사상으로 날개를 갖는 임펠러를 모터로 고속회전시켜 흡입물을 펌핑하는 방식이 적용되고 있다.Conventional pumping methods for pumping water or viscous liquids include pumping suctions as hood valves are opened and closed, or pumping suctions by rotating a radial impeller with a motor at high speed. have.

종래 모터로 임펠러를 고속회전시켜 물이나 점성을 갖는 액체를 펌핑하는 방식은 본인이 선출원하여 등록된 특허 제 175650 호에서 자세히 알수 있는데, 특허된 종래의 진공 흡입 펌프는 도면에 도시한 도 1 내지 도 2 와 같이 흡입구(4)와 배출구(5)가 이어지도록 U자형의 이송홈(6)(7)이 내측에 형성된 내측케이싱(2)과 외측케이싱(3)이 모터(1)의 축방향에 결합되고 상기 이송홈(6)(7)이 형성된 내외측케이싱(2)(3)사이에 방사상의 날개를 갖는 임펠러(10)가 모터축(1a)에 끼워져 장착되는 구조임을 알수 있다.A method of pumping a liquid having water or viscosity by rotating the impeller at a high speed with a conventional motor can be known in detail from Patent No. 175650, which is filed by the applicant. The patented vacuum suction pump is illustrated in FIGS. As shown in FIG. 2, the inner casing 2 and the outer casing 3 having the U-shaped feed grooves 6 and 7 formed therein so as to connect the inlet 4 and the outlet 5 are arranged in the axial direction of the motor 1. It can be seen that the impeller 10 having radial blades between the inner and outer casings 2 and 3 having the transfer grooves 6 and 7 coupled thereto is fitted to the motor shaft 1a.

따라서 모터의 고속회전으로 내외측케이싱에 장착된 임펠러가 고속회전하여 이송홈을 진공상태로 만들어 흡입구로 물이나 기타 흡입물을 진공 흡입해 펌핑하게 된다.Therefore, the impeller mounted on the inner and outer casing rotates at high speed by the high speed rotation of the motor to make the transfer groove into the vacuum state, and the water inlet and vacuum are sucked and pumped by the suction port.

종래의 진공 흡입 펌프는 내외측케이싱에 물의 흡입을 위한 이송홈이 마주하게 형성되고 그 사이에서 양측으로 천공된 공간을 갖는 임펠러 날개가 고속회전해 이송홈을 진공상태로 만들어 진공 흡입하므로써 임펠러 날개의 양측에 공간이 큰 이송홈이 주어져 임펠러가 고속회전시 진공 흡입력이 저하되는 요인으로 작용하고 있다.In the conventional vacuum suction pump, an impeller wing having a space formed on both sides of the inner and outer casings facing each other and spaced in each side is rotated at a high speed to make the conveying groove into a vacuum state, thereby vacuuming the impeller wing. A large feed groove is provided on both sides, which causes the vacuum suction force to decrease when the impeller rotates at high speed.

또한 임펠러 날개가 양측으로 천공된 공간을 갖도록 방사상으로 형성되므로 이송홈내의 공기를 강한 흡입력으로 빨아내지 못해 펌프의 흡입력이 저하되는 문제점이 있으며 흡입물에 포함된 찌꺼기가 흡입되면 내외측케이싱과 임펠러날개 사이에 찌꺼기가 끼어 모터의 과부하 및 임펠러날개의 파손을 일으키고 있다.In addition, since the impeller wing is formed radially to have a perforated space on both sides, there is a problem in that the suction power of the pump is lowered by not sucking the air in the conveying groove with a strong suction force, and the inner and outer casing and the impeller wing are sucked when the residue contained in the suction is sucked. Remnants are caught between them, causing overload of the motor and damage to the impeller blades.

본 발명은 이송홈내의 공기를 강한 흡입력으로 빨아내 펌프의 진공 흡입력을 높혀 공기와 물을 함께 흡입하여 잔여량이 없고 흡입되는 찌꺼기를 절단시켜 흡입해 펌핑하므로 모터의 과부하 및 임펠러의 파손을 방지할 뿐만아니라 고점성을 갖는 액체와 찌꺼기의 펌핑이 가능하도록 하는 것이다.The present invention sucks the air in the conveying groove with a strong suction force to increase the vacuum suction power of the pump to suck the air and water together, there is no residual amount is cut and sucked by the suction pump to prevent damage to the motor overload and impeller It is not to allow pumping of highly viscous liquids and debris.

It is formed in and attached to the outside of the inner casing (2) to be sealed with a plurality of fastening bolts and gaskets.

내측케이싱(2)은 종래 흡입물이 흡입되는 U자형의 이송홈(7)이 형성된 것과는 달리 임펠러(10)가 내장되는 공간만 주어지도록 형성되 모터(1)의 축방향에 체결볼트로 부착된다.The inner casing 2 is formed to be provided only a space in which the impeller 10 is built, unlike the conventional U-shaped feed groove 7 through which suction is sucked, and is attached with a fastening bolt in the axial direction of the motor 1.

상기 내측케이싱(2)의 내측공간에 내장되어 모터축(1a)에 끼워져 장착되는 임펠러(10)는 도면에 도시한 도 4 와 도 5 의 단면도와 같이 방사상으로 날개(11)가 형성되고 한쪽 측면이 칸막이로 막히도록 형성되 막힌쪽이 내측케이싱(2)의 내측면과 접하도록 장착되어 흡입물을 진공 흡입해 펌핑하게 된다.The impeller 10 embedded in the inner space of the inner casing 2 and fitted to the motor shaft 1a has a blade 11 radially formed as shown in cross-sectional views of FIGS. It is formed so as to be blocked by the partition and the blocked side is mounted to contact the inner surface of the inner casing (2) to suck the suction by vacuum pumping.

임펠러(10)는 막힌 한쪽측면이 내측케이싱(2)의 내측면에 밀착되고, 이와 반대쪽면인 날개(11)의 측단면은 외측케이싱(3)의 내측면에 밀착되어 모터(1)의 구동으로 고속회전해 외측케이싱(3)의 이송홈(6)을 통해 흡입물을 진공 펌핑하게 되는데, 다수의 임펠러 날개(11)가 흡입구(4)의 공기를 이송홈(6)으로 끌어들이고 계속적인 회전으로 다시 이송홈(6)의 공기를 배출구(5)로 밀어내어 펌핑동작이 이루어진다.One side of the impeller 10 is in close contact with the inner surface of the inner casing 2, and the side end surface of the wing 11, which is the opposite side, is in close contact with the inner surface of the outer casing 3 to drive the motor 1. It rotates at a high speed in order to vacuum pump the suction through the transfer groove 6 of the outer casing 3, and a plurality of impeller blades 11 draw air from the suction port 4 into the transfer groove 6 and continuously The pumping operation is performed by pushing the air of the transfer groove 6 back to the outlet 5 by rotation.

임펠러(10)의 구조를 다른 실시예로 보이고 있는 도 6 내지 도 8 은 임펠러 날개(11)에 톱날(12)을 형성해 흡입구(4)로 흡입되는 찌꺼기를 잘게 절단시켜 흡입되도록 하는 것으로, 찌꺼기가 임펠러(10)와 내외측케이싱(2)(3)간에 끼어 모터(1)의 과부하와 임펠러(10)의 파손을 방지하기 위한 것이다.6 to 8 showing the structure of the impeller 10 in another embodiment by forming a saw blade 12 in the impeller blades 11 to cut finely sucked debris sucked into the suction port 4, the debris It is to prevent overload of the motor 1 and damage of the impeller 10 by being sandwiched between the impeller 10 and the inner and outer casings 2 and 3.

임펠러 날개(11)에 형성되는 톱날(12)은 막힌쪽과 반대쪽면인 날개(11)의 측단면에 날개(11)의 길이 만큼 형성하되 모터(1)의 회전방향측에 형성하여 흡입되는 찌꺼기를 톱날(12)이 잘게 절단시켜 흡입되게 한다.The saw blade 12 formed on the impeller blade 11 is formed on the side end surface of the wing 11, which is the opposite side to the blocked side, as long as the length of the blade 11, but is formed on the rotational side of the motor 1, sucked debris The saw blade 12 is cut finely to be sucked.

날개(11)의 측단면에 형성되는 톱날(12)은 흡입구(4)의 이송홈(6)에 밀착되어 찌꺼기가 흡입구(4)로 흡입될시 잘게 절단시키는데, 본 발명의 진공 펌프가 양방향으로 흡입 및 배출이 이루어지므로 톱날(12)을 날개(11)의 측단면에 양측으로 형성하여 흡입과 배출이 자유롭게 할 수도 있다.The saw blade 12 formed on the side end surface of the blade 11 is in close contact with the transfer groove 6 of the suction port 4 and cut finely when the debris is sucked into the suction port 4, the vacuum pump of the present invention in both directions Since suction and discharge are made, the saw blade 12 may be formed at both sides of the side surface of the blade 11 so that suction and discharge may be free.

이와같은 본 발명은 종래 내측케이싱(2)에 형성되었던 이송홈(7)을 없애는 한편 내측케이싱(2)의 내측면과 접하는 임펠러 날개(11)의 한쪽 측면을 차단해 막음으로써 천공된 날개(11)와 날개(11)사이로 공기 및 흡입물이 빠져나가는 것을 방지해 진공 흡입력을 높혀 펌프의 성능을 향상시키게 된다.The present invention as described above removes the transfer groove 7 formed in the inner casing 2 while blocking the one side of the impeller wing 11 in contact with the inner surface of the inner casing 2 to prevent the wing 11 Air and suction is prevented from escaping between the blade and the blade 11 to increase the vacuum suction power to improve the performance of the pump.

본 발명은 펌프의 진공 흡입력을 높혀서 공기와 물을 함께 흡입해 흡입물의 잔여량을 없애고 흡입되는 찌꺼기를 임펠러 날개의 톱날로 잘게 절단시켜 펌핑하므로 모터의 과부하 및 임펠러의 파손을 방지할 뿐만아니라 고점성을 갖는 액체와 음식물 찌꺼기의 펌핑이 가능하게 된다.The present invention removes the residual amount of suction by increasing the vacuum suction power of the pump to remove the residual amount of suction and pumps the suction dregs finely cut by saw blade of the impeller blade to prevent overload of the motor and damage of the impeller as well as high viscosity. It is possible to pump the liquid and food waste having.
