Abstract:
The basic structure of the device consists roughly of a breeches pipe (1) where the breeches are joined in a baffle box (2) in which the kinetic energy of the fluid decreases by means of the collision of two jets from the breeches pipe (1). The further flow of fluid containing solid particles or granules flows through channels (4) having outlets (5') at the bottom in which deflectors (5) are located preferably at an angle of 45°. Under the outlets (5') there are tanks (6,9,12) for the deposition of the separated solid material, which, being heavier, is located in the lower layers of the flow of fluid in a dense concentration and which is deflected to the first deposition tanks (6) by means of deflectors (5). The process of separation by gravity is carried out in a single continuous operation.
Abstract:
An apparatus for separating solid materials is described, which comprises a channel for receiving a liquid and the materials to be separated, the channel being provided with an agitation surface. Means for directing streams of fluid at the materials to be separated are provided, the streams of fluid urging the materials over and against the agitation surface to separate the materials. Heavier material is urged along the bottom of the channel to an exit under the action of the streams of fluid, and lighter material separated from the heavier material rises to the surface of the liquid. The agitation surface comprises a plurality of formations each extending across at least a portion of the width of the channel, each formation comprising an ascending surface and a descending surface, at least part of the ascending surface having a steeper slope with respect to the base of the channel than the descending surface. It has been found that the shallower descending surface of one formation followed by the steeper ascending surface of the next formation provides an improvement in agitation of the solid materials as they progress down the descending surface and start to progress up the ascending surface, keeps the transition from the descending surface to the ascending surface clear of a build-up of materials, and provides for the lighter materials to be urged upwards at a suitable angle to reach the surface for removal.
Abstract:
Provided is an electric wire scrap high-grade recovery apparatus with improved recovery rates of copper materials and the like by causing miscut materials contained in crushed materials to be capable of being separated and recovered with good efficiency. [Problem to be Solved] A weir 11 which holds back part of the water flowing on a separation bed 10 in the width direction of the separation bed 10 is provided in a lower part of the separation bed 10, whereby miscut materials 43 contained in crushed materials gather in a region in the vicinity of an upper end of a water pool 12 formed by the weir 11. Therefore, in the above-described region where the miscut materials 43 on the separation bed 11 gather, there are provided on the separation bed partition plates 13, 14 which form miscut material recovery passages 15, 16, whose one end is open and through which the water does not flow, and the miscut materials 43 are recovered by using the miscut material recovery passages 15, 16.
Abstract:
A method of heavy particle separation, including a primary separation stage which includes the steps of dropping, accumulating, concentrating and discharging of heavy particles and/or a secondary separation stage for concentrating heavy particles which includes the steps of infeeding, stilling and retaining such particles.
Abstract:
The invention relates to a method and a device for separating by sedimentation particles from a particle flow contained in a carrier liquid. In order to improve separation efficiency and results, sedimented particles are diverted from the flow at given time intervals during the sedimentation operation in the direction of flow and upstream from flow obstacles without interrupting said operation.
