  • Patent number: 8407849
    Abstract: A cleaning tool includes a mop which includes at a lower end a mop head with a wiping object. The mop includes a mop rod formed of an inner rod and an outer rod and a drive mechanism is used to convert the telescoping motion of the mop rod to rotation motion of the mop head. The drive mechanism is a variable speed drive mechanism. As a result, the mop head of the cleaning tool achieves different rotation speeds under dry working condition with a lower resistance compared to washing conditions with a higher resistance. During washing, the mop head is washed rotationally at a lower speed, and the washing operation is conducted through depressing the mop rod.

  • Publication number: 20120266481
    Abstract: A non-thermal dewatering and drying system to remove, separate and segregate free moisture from an essentially granular form of organic and non-organic solid material mixed with free moisture and air. The energy efficient separation and removal of the free moisture is by the system that creates differential pressures in adjacent moving flows. Such pressure differentials result in the induced flash vaporization of free moisture from granular materials, simultaneously with the separation and segregation of water vapor into a moving flow of adjacent air. The system has a novel design that allows retains laminar/plug flow characteristics. The differential is created by increasing the velocity of the process air as it is introduced into the material transport piping of the system. This combining the material, free moisture and higher velocity air allows for rapid mechanical removal, separation and segregation of free water within the transport pipe.

  • Patent number: 7975605
    Abstract: A food processing device, e.g. a salad spinner, has a housing with a lid, a basket supported in the housing for rotation, and a drive mechanism supported by the lid for rotating the basket to spin water from salad in the housing. The drive mechanism has a crank handle and a drive transmission system coupling the handle to the basket to transmit a rotational driving force from the handle to rotate the basket. The drive transmission system has a first rotary gear arranged to receive the rotational driving force from the handle and a second rotary gear in driving engagement with the first gear for receiving the rotational driving force from the first gear to rotate the basket. The first and second gears have corresponding serial formations, e.g., recesses and protrusions, of respective circular cross-sections that are inter-engageable, one in the other, for transmission of the driving force.

  • Publication number: 20110067257
    Abstract: A Yankee dryer which exploits centrifugal forces to assist in evacuating condensate. A condensate collection system has individual pickup straws arranged at an angle such that the required amount of motive steam pressure is reduced to extract and move the steam condensate from the intake opening of the straw to the discharge point of that straw. The pickup straws communicate with a collection header arranged along the length of the Yankee dryer. The collection header is configured such that it has a radius from the axis of rotation which is greatest near the point at which collected condensate is discharged to a disposal riser conduit which conducts collected condensate to the exterior of the Yankee dryer.

  • Patent number: 7909174
    Abstract: A dewatering structure includes a receptacle body, a dewatering unit and an operation apparatus. The receptacle body includes a receptacle tub and an assembling space, in which the receptacle tub and the assembling space are independent from each other. The operation apparatus includes an operation unit and a base. The operation unit includes an active pedal and a driven pedal, which are pivotally coupled to the base and are intersected with each other. The driven pedal includes a free end slidably coupled with a driving block having a threaded through hole. The threaded through hole is provided for connection with a threaded rod sheathed in a spring member. When the active pedal and the driven pedal are repetitively pressed each other and then released, the dewatering unit is driven to rotate, thus producing a centrifugal force for removing the water from the water-contained object.

  • Publication number: 20100319210
    Abstract: The present invention provides a disc drying device and a disc drying method that allow simultaneous and quick drying of plural discs by a batch process and realize miniaturization of the device. In the present invention, plural discs arranged along a single axis are simultaneously chucked at outer peripheries thereof so that central openings of the discs internally form a space; plural nozzles are disposed in the space so as to supply hot water from inner peripheral surfaces of two sides of each of the discs to heat the discs with the hot water; and the discs are simultaneously rotated to thereby move the hot water from inner peripheries to outer peripheries of the discs and discharge the hot water outwardly of the outer peripheries by centrifugal force. The discharged hot water flows through valley grooves provided in inner wall surfaces of a water receiving cover to the lower side of the discs to be discharged to the outside.
