This invention discloses a paper processing device, comprising a bottom block, a connecting cavity fixedly arranged in the bottom block, a penetrating cavity communicated with and arranged in the lower end wall of the connecting cavity. The penetrating cavity is communicated with the exterior space. A lifting motor is fixedly arranged in the lower end wall of the connecting cavity, the upper end wall of output shaft of which is fixedly provided with a driving pulley. A driven pulley in the connecting cavity is arranged on one side of the driving pulley. The lifting motor works to drive the driving pulley to rotate to drive the driven pulley to rotate, so an inner threaded block is driven to rotate to drive a threaded rod to move upwards; then a stirring fan is driven to enter a reaction cavity. The automatic structure adopted by this device realizes automation of paper processing.

A device (1) for preparing a substance suspension, in particular a pulp suspension, with a container (2), with stator sheets (30) provided in the interior of the container and designed as baffles, and with a rotor (4) in the container, on which rotor a dispersing disk (8) is provided, includes an annular displacement element (20) provided in the interior of the container (2), an element whose outside surface (22) is some distance from the inside surface (23) of the wall (24) of the container (2). The inner opening (21) of the displacement element (20) that is arranged coaxially to the rotor is hopper-like, whereby the expanded area of the opening points to the cover (3) of the container (2). The stator sheets provided in the container span the channel (25) between the exterior (22) of the displacement element (20) and the interior (23) of the wall (24) of the container.

An apparatus for processing a rope formed in a pulper, comprising a conveying mechanism, in particular a winch, for pulling the rope, with the forward end first, out of the pulper, is characterized in that the conveying mechanism is positioned and designed in such a way that the rope can be fed, with the forward end first, directly to a shredder by the conveying mechanism.

A rotor unit in a vessel containing a mixture of water and particles of recycled material, comprising a rotor unit body (19); a screen plate (18) installed to the vessel; a rotor (78) connected to the rotor unit body (19) and configured to rotate inside the vessel, comprising at least two wings (81) configured to slush recycled material in a rotating action and at least two foils (82) configured to clean the screen plate (18) by rotating above the screen plate (18); a space (89) around the rotor (78) defined by a rotor body (77); pipework (21) configured to bring diluting water from outside the vessel to the space (89) around the rotor (78); wherein the rotor body (77) defining the space (89) around the rotor (78) comprises an opening (76) allowing the diluting water to pass through the opening (76) towards the mixture of water and particles of recycled material. The opening (76) at the rotor body (77) is at the same level with the lower edge of the at least two wings (81) or the at least two foils (82), wherein the diluting water is allowed to pass through the opening (76) to the screen plate (18).

The invention relates to a high-concentration mixer (1) for producing a suspension (2), comprising a stationary container (3) and an agitator (8) arranged in the container axis (7), which agitator is connected to a motor via a flange (9) provided in the region of the container bottom (4), which motor is designed for rotationally driving the agitator (8) for mixing the suspension (2) provided in the container (3), wherein the agitator (8) has helical coils (11) which bring about a vertical downward flow (12) of the suspension (2) in the centre of the container (3) and a vertical upward flow (13) of the suspension (2) in the region of the container wall, wherein the flange (9) comprises at least one blade (15) provided on its circumference, which is designed for wiping the suspension (2) from the container (3) and for supporting the vertical upward flow (13) of the suspension (2) in the region of the container wall.

A method of pulping wastepaper includes providing a pulping vessel with a rotor and at least one flow sensor adapted to measure slurry flow within the pulping vessel. The pulping vessel is charged with wastepaper and water to form a slurry, the amounts of wastepaper and water being present such that the slurry has consistency in the range of from 10% to 30%. The wastepaper charge in the pulping vessel is pulped at a pre-selected power level while monitoring poloidal slurry flow in the pulping vessel; and from time-to-time, water may be added to the pulping vessel when the poloidal flow falls below a predetermined lower threshold flow value in order to reduce viscosity and thereby restore poloidal flow within the pulping vessel. Doppler velocimetry is a preferred method of monitoring pulp flow. In a particularly preferred construction the rotor has a variable power drive. The inventive method is especially useful for making high quality, high brightness furnishes from wastepaper which varies from batch to batch.

Embodiments disclosed herein relate to methods and systems for processing and transporting biomass to an end user. In an embodiment, a method of processing and transporting biomass to an end user is disclosed. The method includes tapping a biomass for processing, processing the biomass into a biomass slurry, and transporting the biomass slurry to an end user off site through a transport conduit therebetween.

This specification describes a system and process for treating waste, for example municipal solid waste (MSW) or post-recycling municipal solid waste. The system includes a press and a pulper. The press is adapted to provide a wet fraction of the waste suitable for anaerobic digestion and rejects. The pulper is adapted to receive the rejects and produce pulp. The pulper may be, for example, a drum pulper. In the process, waste is separated into a press into an organic fraction and rejects. The organic fraction is treated by way of anaerobic digestion. The rejects are separated, optionally in a drum pulper, to produce a fraction containing pulp. The pulp can be re-used to make paper or other products. In some case, 70% or more or 80% or more of MSW can be diverted from landfill.
