Patent number: 8641264Abstract: The present invention provides a method for producing paint and a system for producing paint, which enable, in a paint-producing process, moderate stirring and dispersive mixing without causing entrainment of air bubbles, and are also economically advantageous and easier to clean. The system includes a tank 2 for receiving a paint material to be mixed and dispersed, a pump 3 for sucking part of the paint material in the tank 2 and discharging the sucked paint material into the remaining part of the paint material in the tank 2, and a flow path reduction area 5 disposed between the pump 3 and a paint material discharge outlet 4, the discharge outlet 4 being positioned so as to be submerged in the paint material in the tank. This achieves the stirring, mixing, and dispersion.Type: GrantFiled: November 10, 2005Date of Patent: February 4, 2014Assignee: Kansai Paint Co., Ltd.Inventors: Hidenori Sawada, Masahiko Hiraki

Patent number: 7540651Abstract: An agitator able to mix and disperse a variety of fluids of various fluid volumes with different viscosities ranging from low to high, and having excellent, cleanability and improved cooling efficiency is provided. The agitator comprises a rotating shaft 3 extending vertically inside an agitating vessel 2, and a flat paddle blade 4 mounted on the rotating shaft 3. The flat paddle blade has a bottom flat paddle blade portion 4a extending outwards from the bottom of the rotating shaft 3 and a rectangular upper flat paddle blade portion 4b extending upward from an upper part of each side end of the bottom flat paddle blade portion 4a. The dimensional ratio (b/a) of the blade diameter (b) of the bottom flat paddle blade portion 4a to the inner diameter (a) of the agitating vessel 2 is from 0.6 to 0.9, and the dimensional ratio (d/c) of the height (d) of an upper flat paddle blade portion 4b to the height (c) of the bottom flat paddle blade portion 4a is from 1 to 4.Type: GrantFiled: March 28, 2005Date of Patent: June 2, 2009Assignee: Kansai Paint Co., Ltd.Inventors: Hiroyuki Matsumoto, Mutsuo Kuramoto, Masahiko Hiraki
