Title: Ultrafilter
Inventor: KUMAGAI MASAHIKO
IPC: B01D61/18
Filed: 1985-03-26
Abstract: PURPOSE:To reduce the height of a machine, to prevent the machine from vibration and sound, and to save the necessary power by attaching a cartridge of an ultrafilter membrane to the inside of a covered housing connecting an upper conducting pipe and lower conducting pipe fitted radially to the top and bottom ends of a casing of a submergible axial-flow pump installed with a motor. CONSTITUTION:Feed water introduced into a casing 20 of a vertical pump from a feed water introducing pipe 34 is flowed upwards by driving an impeller 30 with a motor 32. The water is dispersed radially by a funnel-shaped expanding part 24 and a dispersing cone 26 for the feed water and filtered by suction when the water passes through a curved upper conducting pipe 36 flowing downwards through a cartridge 50 of an ultrafiltration membrane in the housing 40. The water is then circulated through the lower conducting pipe 37. the permeated water having permeated the ultrafiltration membrane is taken out of a water sucking fitting 52 and a water collecting pipe 53 as treated water. When the filtration membrane is clogged, the filtration operation is interrupted, and the motor 32 is driven in the reverse direction to flow a large amt. of feed water through the cartridge 50 for washing the filtration membrane.

Filed: 1980-05-08
Abstract: PURPOSE: To decrease power consumption by a method wherein the slow effect of a spool valve is induced, and a diameter of an inlet port of a pilot oil chamber can be increased.  
     CONSTITUTION: When a change-over valve 22 is changed over to a location of 22a, compressed oil flows through an oil chamber 14 through an oil chamber 15 and a check valve 8, and reaches an oil chamber 23a at the load side through an opening section 3 and a duct 24. When the change-over valve 22 is returned to a neutral location 22b, the check valve 8 is closed, and compressed oil in the oil chamber 23a is interrupted by the oil chamber 14 and an oil chamber 16. When the change- over valve 22 is changed over to a location of 22c, compressed oil reaches an oil chamber 23b at the nonload side while functioning to an oil chamber 13. Since a compensator 12 is moved left, a spool valve 5 is moved left through the check valve 8 and a seat surface 7 is released, the compressed oil reaches the oil chamber 15, being controlled by means of a notch 18 and returns to a tank. In this case, force pushing the spool valve 5 right is only the reaction of a spring 6.
