The inlet and outlet each include a filter element that keeps the catalyst in the reactor. The reactor also includes a device that ensures homogeneous distribution of the catalyst and the starting materials in the reactor. This reactor can carry out reactions at a high solids content without the catalyst having to be separated off from a product stream in an extra process step and without regular cleaning and thus shutdown of the process being necessary.

  • Publication number: 20090050580
    Abstract: To provide a filtering apparatus and a filtering method, in which dewater performance is improved while downsizing of the apparatus is achieved. The filtering apparatus includes a cylindrical or conical inner screen 1 and an outer screen 2 which are concentrically disposed and a spiral fixed wall 3 which is disposed in a filtering room 4 between the inner screen 1 and the outer screen 2. Only the inner screen 1 and/or the outer screen 2 are/is rotated about a shaft center while the spiral fixed wall 3 is not rotated. During this manipulation process, a treated feed is fed into the filtering room 4 from one end of the filtering room 4, thus treated liquid is filtered through the inner screen 1, and is filtered through the outer screen 2, so that each filtrate is discharged to the outside, and a cake is discharged from the other end of the filtering room 4.

    Abstract: Rotor unit for a centrifuge for purifying flowing fluids, which rotor unit (12) comprises a plurality of disk elements (14) which are stacked concentrically one on another and provided with at least one centrally located fluid flow-through hole, where the disk elements (14) have lead-through openings by means of which the disk elements (14) are pushed onto a number of essentially axially elongate guide elements (16) distributed in the circumferential direction for guiding the disk elements in the circumferential direction and radially. The disk elements (14) are held together by a first and a second end element (18, 20) at the ends of the stack of disk elements. A central portion of at least some of the guide elements (16) are interconnected by means of a cross-stay construction (36) in order to prevent deflection of the rods owing to the centrifugal force during rotation of the rotor unit (12).

  • Patent number: 7299745
    Abstract: A juice press as used in the production of wine for removing liquids from solids, having a horizontally positionable press frame that allows a vertical press mechanism to be rolled to a first position for interference-free loading of a press basket with material to be pressed, and then rolled to a second operating position located over the press basket. The press basket has a liquid channeling plate having an arrangement of holes and channels that creates a perimeter seal along a circumference at the bottom of a loaded press basket. The liquid channeling plate traps naturally occurring sludge along the circumference bottom and allows for efficient evacuation of extracted juice from the bottom of the basket as the press mechanism is operated.

  • Patent number: 6866777
    Abstract: A laminated modular water filter includes superposed annular plates. A filter unit is disposed between each adjacent pair of the annular plates. The annular plates include a top plate, a bottom plate, a plurality of intermediate plates, and at least one flow-guiding plate sandwiched between two of the intermediate plates. Each of the top plate, the intermediate plates, and the bottom plate has an annular outer passage unit in fluid communication with a curved outer passage unit in the flow-guiding plate. Dirty water is introduced into two side openings in the top plate, and flows into central holes in the annular plates via the filter units so as to form filtered water. Solid particles in the dirty water are guided into two side openings in the bottom plate via the annular outer passage units and the curved outer passage unit.
