Abstract: A mop wringer comprises a housing supporting a first roller and a second roller. The first roller is supported by the housing in a first position where the first roller is spaced from the second roller a first distance and in a second position where the first roller is spaced from the second roller a second distance. The second roller is supported on an arm where the arm moves relative to the housing to move the second roller toward and away from the first roller between a third position and a fourth position. A drive mechanism moves the arm between the third position and the fourth position and rotates the roller in the fourth position.

Abstract: The scent removing device has a housing that forms an interior compartment. The compartment is separated into a first and second portion by a shelf that is disposed within the compartment and connected to the interior of the housing. The shelf has at least one channel and a plurality of openings to permit air to flow between the first and second portions. An air tube extends from the first portion, through the shelf to the second portion. A fan motor is in communication with the air tube to blow air through the air tube and into the second portion.

Abstract: The invention relates to a device for feeding a drying gas to a mixing granulator comprising a mixing chamber and a rotating agitator (3), on which mixer blades (4) are arranged in a radial position with respect to a drive shaft (5). The feeder line (6) for the drying gas is disposed inside the drive shaft (5) of the agitator (3). An exit line (7) is respectively connected in the region of each mixer blade (4), said line terminating in at least one outlet (8) arranged underneath and, in the direction of rotation, behind the mixer blades (s). The outlet (8) extends advantageously in at least partial manner along the mixer blades (4), embodied in the form of a slit or in a flat manner in the form of a porous element.

Abstract: An improved centrifugal pellet dryer that employs forced air in the direction opposite that of the pellet travel through the dryer. The air may be preheated depending on the particular product. The resulting airstream reduces water spray and lowers the humidity level of the air in the dryer system. The airstream exits the dryer at or below the lower level of the rotor, thus providing increased exposure to the airflow. The result is enhanced drying effectiveness and increased dryer capacity.

Abstract: The present invention relates to a rotating fluidized bed apparatus for powder particle. A gas circulation path is formed at the periphery of the treatment chamber 2 via the circumferential faceplate 202, 212, and the circumferential faceplate is adapted to rotate around an axis. Behavior of powder particles can be controlled by introducing gas from the periphery of the treatment chamber via the circumferential plate 212 to exert centripetal force on the powder particle, while exerting centrifugal force on the powder particles accompanying rotation of the circumferential plate 212.

Abstract: A bottom element for a device for treating particulate has a two-dimensional body having numerous apertures. Means for imposing to a treatment medium passing said bottom are provided. Said bottom being designed as blade-shaped body, said apertures being designed as slots, said slots being generated by a removal of material from said plate-shaped body. Said slots having side walls sloping towards a plane of said body. For facilitating a cleaning of said bottom said side walls of said slots further consecutively tapers to a direction of a side of said bottom a particulate material rests.

Abstract: The operation of dewatering and drying devices which consist of a dewatering centrifuge and a concentrically arranged spray drier may be disturbed by leaks between the drier housing and the centrifuge or by deposits and encrustation of solid particles inside the drier. In order to avoid these disturbances, the rotating outer surface of the centrifuge (1) is sealed with respect to the fixed front walls (13, 14) of the drier housing (11) by a sealing system in two or more stages which consists of rotary seals (160) and elastic or sliding sealing elements (180, 260, 300, 340). The rotating outer surface of the centrifuge (1) is provided, with turbulence-generating means (32, 33, 40, 42, 46), preferably torus-shaped turbulence-generating rollers, arranged inside the drier housing (11).

Abstract: A method of drying organic or inorganic material or a mixture thereof, said material containing a liquid or liquids, which comprises introducing said material interiorly of a rotating rotor carrying on its periphery oscillating rotor blades, said rotor rotating about the axis of a process chamber having an inner surface with substantially axially extending ribs, said rotating rotor causing the material introduced interiorly of said rotor to be propelled radially outwardly of said axis of rotation and to expel liquid or liquids from said materials, and the oscillating rotor blades and the opposing ribs causing vibrational forces and turbulence to be induced into the outwardly flowing liquid so as to form a mist. Apparatus for carrying out said method is also described.

Abstract: An apparatus for detaching a filter cake created by a suction dryer from off the filter surface of a filter medium and for an essentially simultaneous treatment of the cake to a form advantageous for further processing. The apparatus comprises a suction dryer (1, 11, 27), a connected filter surface (4, 14, 28) and a basin (2, 13, 27) for the material to be filtered. According to the invention, in the vicinity of the filter surface (4, 14, 28) of the filter medium, there is installed a blowing member (7, 17, 21) with at least one part, the blowing effect whereof can advantageously be extended over the whole width of the filter surface (4, 14, 28) of the filter medium, on which surface the filter cake can be formed.

Abstract: An improvement to a coal processing system where hard materials found in the coal may cause jamming of either inflow or outflow rotary airlocks, each driven by a reversible motor. The instantaneous current used by the motor is continually monitored and compared to a predetermined value. If an overcurrent condition occurs, indicating a jamming of the airlock, a controller means starts a "soft" reverse rotation of the motor thereby clearing the jamming. Three patterns of the motor reversal are provided.

Abstract: An improved slurry dryer of the type having a plurality of beater blades carried on a rotating shaft in a cylindrical housing, the improvement in combination therewith of a plurality of scraper blades mounted on at least one disk carried by the rotating shaft at the inlet end of the dryer for scraping the cylindrical side wall and the end wall to prevent the material entering the dryer from adhering and remaining on the side and end wall of the cylindrical housing. The scraper blades are replaceable and adjustable with respect to the side and end walls of the housing by slotted mounting to accommodate wear of the scraper blades. An air dam in the form of a radially extending disk is provided downstream of the scraper blade disks to direct drying air radially outward to impinge on the slurry material to be dried.

Abstract: A reactor for drying solids in a heated fluidized bed comprising over the fluidized bed a vapor-collecting space provided with a vapor outlet. Means for feeding the water-containing solids are provided over the vapor-collecting space. A conical distributor surface, which is rotatable about a vertical axis, is provided in the vapor-collecting space below the supplying means and slopes at an angle of 25.degree. to 70.degree. from the horizontal and is formed with at least one aperture. The aperture occupies 10 to 90% of the theoretical overall area of the distributor surface. The distributor surface is rotated at a speed of 20 to 250 revolutions per minute.
