APPARATUS FOR DISPENSING MATERIAL

ABSTRACT APPARATUS FOR DISPENSING MATERIAL Apparatus for spreading manure comprises an elongate hopper 12 mounted on a mobile frame. An axial feed rotor 18 runs along the inside of the base of the hopper and urges manure forwardly to a transfer rotor 25 which pushes the material sideways through an opening 21 to an overshot impeller 23 which throws the manure sideways from the apparatus. On the axial feed rotor 18 are blades 19 extending outwardly from the axis of the rotor and inclined in such a manner as to, push the material along the direction of the axis. The blades 19 are positioned on a reverse helical path around the rotor axis, the sense of the reverse helical path being opposite to the sense of inclination of the individual blades. In this arrangement the efficiency of axial delivery of the rotor 18 is substantially lower than if the blades were positioned along a helical path around the rotor axis having the same sense as the inclination of the individual blades. The reduced efficiency of axial delivery of the rotor can be matched to the capability of the sideways-directed impeller 23.

CENTRIFUGAL SEPARATOR CAPABLE OF PERFORMING SELECTIVE SEPARATION USING SPECIFIC GRAVITY DIFFERENCE

The present invention relates to a centrifugal separator and, more particularly, to a centrifugal separator capable of performing selective separation using a specific gravity difference. According to the present invention, delay holes are formed in delay blades and inter-delay blade pitch is increased or decreased in separating industrial waste slurry into a supernatant and solid matter inside a counter-rotating body in which a conical upper rotating body and a cylindrical lower rotating body have a vertical formation and a delay screw conveyor provided with the delay blades is installed. As a result, a path along which the industrial waste slurry moves while being subjected to a centrifugal force in a case increases. Accordingly, not only heavy and voluminous solid matter but also lighter and less voluminous solids can be efficiently separated. Examples of the latter include diamond, sapphire, and copper powder that may result from polishing work. COPYRIGHT KIPO 2017 ...

Reactor for counter-current treatment of solids and liquids

The invention relates to a reactor for counter-current treatment of solids and liquids in a centrifugal force field, especially for finely divided solids which are readily suspendable in liquids. The reactor comprises a rotating drum 1 in which a co-rotating single- or multi-start worm 4 for conveying and processing the solids is axially arranged on the inner wall of the drum. Each worm flight consists of two screw threads disposed behind one another of the most widely variable designs. The first screw thread 7 essentially fills the entire diameter of the drum 1 and has numerous breaks 27 in the form of gaps or slits or is formed of offset screw thread elements 28. The second screw thread 6 disposed behind the first forms, in contrast, a gap with the inner wall of the drum and can be designed to be continuous without breaks. During operation of the reactor, the sedimented solids are conveyed on the basis of a differential velocity between drum 1 and worm 4. In the process, the first screw thread 7 collects, rearranges and, in each case, conveys the solids up to a break, and the solids deposited by the first screw thread 7 on the inner wall of the drum in the form of streaks are once more spread uniformly in the conveying direction by the second screw thread 6. In this manner, the surface of the solid is constantly and repeatedly renewed while being conveyed through the reactor, and as a result the intended reactions, for example mass transfer between liquid and solid, are intensified. The counter-current is achieved by feeding in the liquid 13 on the side of the drum 1 facing the infeed of the solid 12, and by arranging a weir 21 for the liquid discharge 17 and designing one side of the drum in conical form 3 up to the solid discharge 16. <IMAGE>

本发明公开了一种带副叶片的螺旋输送器，中空内筒设置有锥段与直筒段，靠近锥段的管壁上开设有进料孔，内筒的外周设置有螺旋叶片，在螺旋叶片之间设置有若干副叶片，所述副叶片的宽度小于螺旋叶片的节距，相邻的两片副叶片交错设置在螺旋通道空间内形成曲折流道。本发明通过在螺旋叶片之间增加副叶片，副叶片随内筒一起旋转，进入螺旋输送器的悬浮液在巨大离心力场作用下，固体颗粒从液相中分离出来，副叶片的存在改变了原来仅以螺旋叶片驱动液体旋转的方式，而是通过副叶片驱动从出料孔进入内外筒之间的悬浮液，使之能立即获得离心力和转速，从而加速固液两相的分离，提高分离效率。同时副叶片也增加了当量沉降面积，取得更好的分离效果。

Scroll-discharge device for scroll-discharge screen centrifuge

Decanter centrifuge

The invention relates to a decanter centrifuge comprising a rotatable drum (10) which tapers conically into a solids outlet (54) and forms a liquid outlet (60) at the opposite end, a stationary inlet tube (42) which leads axially into the drum for supplying a suspension into the interior of the drum, and a screw (20) which is rotatably arranged in the drum and which surrounds an outlet end (44) of the inlet tube and forms a helix (30, 32) that reaches the inner circumferential surface of the drum (10). The invention is characterized in that the helix (30, 32) of the screw (20) is held on axially running support walls (34) at least in one section (22) axially adjoining the liquid outlet (60), said walls being arranged around the outlet end (44) of the inlet tube (42) in the shape of a star.

PCT No. PCT/SE96/01622 Sec. 371 Date Sep. 15, 1998 Sec. 102(e) Date Sep. 15, 1998 PCT Filed Dec. 10, 1996 PCT Pub. No. WO97/23295 PCT Pub. Date Jul. 3, 1997In a decanter centrifuge, which comprises an outer drum (1) and an inner drum (5) concentric therewith, the two drums being rotatable at different speeds around a common center axis, the inner drum (5) carries several blades (6, 7) arranged to convey axially in the outer drum (1) sludge having settled on the inside of the drum. The blades (6, 7) are placed in parallel blade rows, each of which extends in a certain pitch along a first helical line (9, 10) around at least part of the center-axis. Each one of the blades extends along a second helical line (29c), which has a pitch opposite the pitch of the first helical line (9, 10). The distance between the rows of blades is substantially larger than the distance between two adjacent blades in one and the same row. Possibly, the inner drum may be provided with only a single row of blades.

Centrifugal sedimentation control device

A centrifugal sedimentation control device is provided to control the input amount of materials by regulating the linear velocity of input materials, a sedimentation area, and differential speed of a screw conveyor by adjusting the ejection length of a scattering ejection unit according to property values of the input materials. In a centrifugal separator having a cylindrical rotary shaft formed in a rotary cylinder(210) and a screw conveyor having a continuous spiral plate formed around the periphery of the rotary shaft, the rotary shaft is composed of a scattering ejection unit formed on the peripheral surface to pour the external input materials into the rotary cylinder and a feed pipe(260) inserted into the rotary shaft to adjust the ejection length of the scattering ejection unit and reciprocate in an axial direction and guiding the input materials to the inside of the rotary shaft. A tip blade(228) formed in the shape of a tail of a dove is formed on the circumferential peripheral surface of the plate of the screw conveyor to prevent wear.
