Patent number: 9458939Abstract: A butterfly valve has a circular plate-shaped valve element, a pair of support shafts, a pair of support shaft moving units, and a drive shaft. The valve element is seated on and removed from the valve seat from below. The drive shaft drives and rotates the support shafts. As the support shafts are rotated by the drive shaft, the valve element is rotated and inverted. The support shaft moving units include decentered shafts that are rotatably supported by casings and in which the support shafts are respectively inserted in a decentered state, and air cylinders configured to apply a force to the support shafts in the upward and downward direction. When the valve element is seated on or removed from the valve seat, the valve element is moved in the upward and downward direction in a horizontal posture as the air cylinders operate.Type: GrantFiled: September 29, 2010Date of Patent: October 4, 2016Assignee: KABUSHIKI KAISHA POWREXInventors: Yasuhiro Hotta, Takashi Sakamoto

Patent number: 9266142Abstract: A partition portion includes a proximal portion fixed to the outer periphery of the peripheral wall portion and a sealing member mounted to the proximal portion in a manner that the sealing member is allowed to move in inner and outer circumferential directions of the peripheral wall portion. When receiving a force toward an outer circumferential direction, the sealing member is moved in the outer circumferential direction, and a distal end portion thereof is held in press-contact with a sliding contact portion of a ventilation member with a force generated along with the above-mentioned force.Type: GrantFiled: September 6, 2012Date of Patent: February 23, 2016Assignee: KABUSHIKI KAISHA POWREXInventors: Koji Hasegawa, Yasuhiro Hotta, Naotoshi Kinoshita, Tarou Endou, Shuichiro Fukuda, Kazuhiro Uchida, Yosuke Tomita, Hitoshi Kamada, Kazunori Wakabayashi

Patent number: 8671877Abstract: A measuring unit 13 is provided inside a rotary drum 11. The measuring unit 13 is provided with a light transmitting member 13a and an optical sensor 13b that are provided at the central region on the inner wall of the other end portion 11b. When particles are subjected to a coating treatment, information as to the properties (such as the coating thickness, the moisture, the coating performance, and the impurity) of the particles of a particle layer A being brought into contact with the surface of the light transmitting member 13a is measured on a real-time basis by the NIR sensor 13b via the light transmitting member 13a. The data is processed by the processing unit of the NRI spectroscopic analyzer to thereby perform monitoring.Type: GrantFiled: December 2, 2010Date of Patent: March 18, 2014Assignee: Kabushiki Kaisha PowrexInventors: Koji Hasegawa, Takuya Nagato, Koh Matsui

Patent number: 7836842Abstract: Provided is a coating apparatus, which has satisfactory operability at a time of installing or exchanging a spray nozzle, is not complicated in structure, and is advantageous in terms of layout. A rotary drum (2) is rotated around an axis (A) inclined with respect to a horizontal line, and has an opening (5) at one end on an inclination upper side. A spray nozzle unit (10) is removably attached to a swing arm (34), and the swing arm (34) can swing with respect to a swing axis (34c). Owing to the swing operation of the swing arm (34), the swing nozzle unit (10) can be moved between the inside and the outside of the rotary drum (2).Type: GrantFiled: July 15, 2005Date of Patent: November 23, 2010Assignee: Kabushiki Kaisha PowrexInventors: Koji Hasegawa, Hiroshi Matuura, Yasukazu Nishimura

Patent number: 7614359Abstract: The rotating drum 2 rotates around an axial line A that is inclined to the horizontal at a present angle ?. Process gas flows in the rotating a drum 2 from an air vent 7a of an air duct 7 through an air inlet 5 at one end of the rotating drum 2, passes through a layer of granules 11, and flows out into an air outlet duct 8 through an air vent 21a of a first disc plate 21 and a connection hole 22a in a second disc plate 22.Type: GrantFiled: July 1, 2003Date of Patent: November 10, 2009Assignee: Kabushiki Kaisha PowrexInventors: Koji Hasegawa, Hiroshi Matsuura, Tetsuya Murakami, Takashi Sakamoto

Patent number: 7297314Abstract: A fluidized bed apparatus has a rotary rotor 4 arranged at the bottom center thereof, a disintegrator mechanism 5 arranged above the rotary rotor 4, and a cylindrical draft tube 6 installed above the disintegrator mechanism 5. A fluidizing gas jetted from a gas dispersion plate 3 causes powder particles P in a processing container 1 to form a fluidized bed in which they circulate so as to ascend through the gap between the outer periphery of the rotary rotor 4 and the bottom inner wall of the processing container 1, the space between the disintegrator mechanism 5 and the inner wall of the processing container 1, and the space between the outer periphery of the draft tube 6 and the inner wall of the processing container 1, and descend through the inner portion of the draft tube 6.Type: GrantFiled: July 30, 2003Date of Patent: November 20, 2007Assignee: Kabushiki Kaisha PowrexInventors: Susumu Natsuyama, Nobuyuki Watanabe, Kazuyoshi Otaki, Kenji Nagatsuma, Takuya Nagato, Yoshiyuki Kanoh, Ran Tabata, Makoto Kobayashi

Patent number: 5336332Abstract: Means is disclosed for washing the inside of a pelletizing machine containing a bag filter which is capable of being raised and lowered within the body of the machine. A vertically movable, upright means to spray washing liquid in three dimensions is provided above the bag filter. A horizontally movable spraying means is provided below the bag filter. This horizontal spraying means can be retracted from inside the pelletizing machine during pelletizing operations, but is capable of spraying washing liquid upwardly into the open end of the bag filter during washing operations.Type: GrantFiled: September 10, 1991Date of Patent: August 9, 1994Assignees: Kabushiki Kaisha Powrex, Kabushiki Kaisha Ariwa SeisakushoInventors: Katsuhiko Satoh, Itsuo Muto, Shigeki Takeda, Mamoru Miyamoto

Patent number: 5188134Abstract: Each of the washing units A and B comprises an openable and closable pinch valve unit 4 branchwise connected to a pipeline C, an autofeeder unit 5 for controlling the feed for advance and retraction movement of a high pressure hose 6 having rotatable nozzle unit connected to the front end thereof, and a hose reel unit 7 for winding and unwinding the high pressure hose. During washing operation, the nozzle unit enters the pipeline C through the pinch valve unit 4 now opened to wash the inner surface of the pipeline. During nonwashing period, the nozzle unit is moved rearward and completely isolated from the pipeline by the pinch valve unit 4 now closed. Therefore, the washing units A and B are completely separated from the pipeline C during nonwashing period.Type: GrantFiled: September 10, 1991Date of Patent: February 23, 1993Assignees: Kabushiki Kaisha POWREX, Kabushiki Kaisha Arikawa SeisakushoInventors: Katsuhiko Satoh, Itsuo Muto, Shigeki Takeda, Mamoru Miyamoto
