Patent number: 8961001Abstract: Provided are an agitator and an agitating hook provided therein. The agitator includes a rotary shaft rotatably installed in a reactor, rotor blades installed at an outer circumference of the rotary shaft and rotated with the rotary shaft to agitate a material therein, and an agitating hook constituted by a pair of members spaced apart from each other at an inner wall of the reactor and through which the rotor blades pass. Here, a gap between the agitating hook is larger at an outlet port through which the rotor blade leaves than at an inlet port through which the rotor blade enters. Since a pressure is uniformly applied from the inlet port through which the rotor blade enters to the outlet port through which the rotor blade leaves, a torsional moment applied to the agitating hook is minimized. Therefore, it is possible to improve durability of the agitating hook and increase reliability of products.Type: GrantFiled: October 29, 2010Date of Patent: February 24, 2015Assignee: LG Chem, Ltd.Inventors: Yeon Seok Choo, Hyo Sook Cha, Ye Hoon Im, Byung Woo Choi, Jin Hyun Bae

Patent number: 6830369Abstract: A mixer apparatus for use with a vessel centered about a longitudinal axis is disclosed. The mixer has a tubular blade which: defines a central head axis; has a first end and a second end spaced from the first end along the head axis; and tapers from the first end to the second end. The inner surface of the blade and the second end define an inside blade diameter “ID” and the outer surface of the blade and the first end define an outer blade diameter “OD”. The blade is positioned within and coaxial to the vessel. A scotch yoke, operatively connected to the blade by a shaft, effects reciprocating longitudinal movement of the blade through a stroke “S”, with a duration “T” for each cycle, wherein 175≦0.36×OD2/ID2×S/T≦250 when OD, ID and S are expressed in inches, and T is expressed in minutes.Type: GrantFiled: November 15, 2002Date of Patent: December 14, 2004Assignee: Enersave Fluid Mixers Inc.Inventors: Gary Haughton, Martin Behr, Tom Ostrowski

Publication number: 20040085856Abstract: A mixer of fluids, such as paint or resins, having a shaft capable of rotating about a longitudinally-extending, centerline axis of the shaft and at least one rotor assembly that is fixedly connected to and axially-aligned of the shaft. The shaft rotates about its centerline axis as well as each rotor assembly. Each rotor assembly consists of a plurality of spaced apart rotors. Each rotor has substantially uniform upper and lower surfaces and generally smooth and uniform edges. In preferred form, each rotor is a smooth disk that may be flat, wavy, concave, convex, dimpled, or tilted in shape.Type: ApplicationFiled: October 30, 2002Publication date: May 6, 2004Inventor: James K. Murosako

Patent number: 6616318Abstract: A mixing apparatus for mixing material in a container comprising a base mixing element and an upper mixing element wherein the upper mixing element can be rotatably and reciprocatably coupled to the base mixing element. The base mixing element can be formed by an elongate member that is fixed to a base plate. The upper mixing element can be formed by an elongate member, which can comprise a cylinder, that has a plurality of mixing arms fixed thereto. An aperture can be disposed adjacent to a proximal end of the elongate cylinder of the upper mixing element for allowing material to be exhausted and cleaned from within the elongate cylinder. The mixing arms can have a plurality of apertures therein, and the base plate can have a peripheral rim for maintaining the base plate spaced from the bottom surface of the container. A plurality of angled blades can be formed in the base plate for drawing material through apertures in the base plate.Type: GrantFiled: June 8, 2001Date of Patent: September 9, 2003Inventors: Jesse M. LeBlanc, Ajay M. Pathak
