초록 ▼

An apparatus for the compaction and reduction of liquid content in a material includes at least one floating helix (3) rotatable about its axis by drive means (4, 30) and disposed in a casing (2) which, at least along a portion of its extent in the longitudinal direction, completely encloses the helix. In conjunction with the discharge portion of the apparatus, the casing encloses the helix with slight play. Seen in the direction of movement of the material, the discharge portion includes a helix-free region most proximal the discharge opening of the casing, intended for the formation of a counterpressure member which arrests the movement of the material. In this region, the helix is provided with an extension body (100) which reduces the available conveyor surface area. As a rule, the body is a cylindrical hollow body which as a rule is provided with drainage apertures.

대표청구항 ▼

An apparatus for the compaction and reduction of liquid content in a material in which the apparatus includes a floating, shaftless helix with a hollow center (3, 53) rotatable at one end about its axis by drive means at said one end of the helix, said helix being disposed in a casing (2, 52) which, at least along a part of its extent in the longitudinal direction, wholly encloses the helix, said casing including an infeed portion and a discharge portion with a discharge opening, the casing surrounding, in the region of the discharge portion, the helix with slight play, and also embracing a region most proximal the discharge opening of the casing where no helix is present, for the formation of a compaction zone in which movement of the material is resisted, said apparatus further comprising in the discharge portion of the casing, an unsupported elongate body (100) fixed to the helix and extending aubstantially in the axial direction thereof to arrest the movement of said material, said shaftless helix comprising a continuous blade wound spirally at a determined pitch, said blade extending substantially radially in said casing and having a radial extent to form said hollow center with an open central axial passage longitudinally along the length of said helix for passage of said material therethrough, wherein the perimeter of said hollow center is defined by said continuous spiral blade at the inner edge thereof, said elongate body extending in continuation of said axial passage axially thereof.
