Abstract
The invention relates to a winnowing box, which consists of a feeding hole, a discharging hole, an intercepting plate, collecting hoppers, an intercepting net and an air outlet, and is characterized in that: a lower supporting plate of the feeding hole is circular-arc-shaped, and is tangential to the horizontal plane; three collecting hoppers are arranged horizontally in sequence; the intercepting plate is arranged among the collecting hoppers; the intercepting net is arranged at the front end of the air outlet; the front end of the intercepting net is provided with a section of oblique panel; and the entire device is enclosed by using a box body plate. In the invention, materials of different densities or particle sizes displace in different ways in the horizontal direction during falling under the action of gravity and horizontal wind power and enter three different collecting hoppers under the intercepting action of the intercepting plate, so that material separation is realized. The winnowing box is easy to manufacture, is convenient for managing and running, has a certain dust-proof function, has a good separation effect on materials which can be separated according to densities or particle sizes, and has remarkable advantages when used in dressing plants in drought regions.
Description
Technical field
The present invention relates to a kind of selection by winnowing case, belong to the preparation equipment field.
Background technology
Along with growing tension and China of water resource has considerable ore dressing plant to be positioned at the drought and water shortage area; Common wet split more and more is restricted; Therefore dry separation shared proportion in ore dressing can increase gradually, and pneumatic separation is a kind of cheap effective dry separation that is easy to get, and has the advantage that product needn't dewater; Can save product is dehydrated the operation that this road bothers very much and expense is high; In addition can energy savings, environmentally safe or pollute very for a short time, stepping up to develop pneumatic dry separator preparation equipment miscellaneous is trend of the times.
Summary of the invention
The purpose of this invention is to provide a kind of selection by winnowing case, utilize the acting in conjunction of horizontal wind-force and gravity that density or the different material of granularity are carried out dry-type separation, be particularly suitable for ore dressing plant, drought and water shortage area and use.
Technical solution: the present invention is made up of feeding mouth, air intake vent, section flitch, aggregate bin, interception net, exhaust outlet; Wherein the lower supporting plate of feeding mouth is circular arc and tangent with horizontal plane; Three aggregate bin levels are arranged in order, and are provided with between the aggregate bin to cut flitch, and the exhaust outlet front end is installed the interception net; Interception net front end is provided with one section skewback, and whole device seals with box plate.
Treat among the present invention that sorting material gets into the selection by winnowing case from feeding mouth along lower supporting plate,, the speed of a horizontal direction is arranged when making material break away from lower supporting plate, do level throw motion because lower supporting plate is circular arc and tangent with horizontal plane.High wind is blown into the selection by winnowing case from the air intake vent level; Under the acting in conjunction of wind-force and gravity; Can produce the displacement of differing in size in the horizontal direction in the different material dropping process of density or granularity, the horizontal displacement of the material that density is big or granularity is big is little, and the horizontal displacement of the material that density is little or granularity is little is big; Under the interception that cuts flitch, fall into three horizontal different aggregate bins respectively, realized the sorting of material by density or granularity.Wind receives the barrier effect of skewback, produces to stream to converge to the exhaust outlet discharge.The interception net can be with the dust interception of being carried by wind, and dust slips in the terminal aggregate bin along skewback, has reduced the loss of material, and dustproof effect is arranged simultaneously.Whole device is sealed by box plate, can prevent to produce dust polluting environment in the production process, has improved working environment.
The present invention makes simply, and management operating is convenient, has certain dust reduction capability, to can good separating effect being arranged according to the material that density or granularity are carried out sorting, uses in the ore dressing plant in drought and water shortage area to have clear superiority.

The specific embodiment
Embodiment: in Fig. 1; The present invention is made up of feeding mouth 1, air intake vent 3, section flitch 4, aggregate bin 5, interception net 6, exhaust outlet 8, and wherein the lower supporting plate 2 of feeding mouth 1 is circular arc and tangent with horizontal plane, and three aggregate bin 5 levels are arranged in order; Be provided with between the aggregate bin 5 and cut flitch 4; Exhaust outlet 8 front ends are installed interception net 6, and interception net 6 front ends are provided with one section skewback 7, and whole device is with box plate 9 sealings.
Treat that sorting material 2 gets into the selection by winnowing casees from feeding mouth 1 along lower supporting plate,, the speed of a horizontal direction is arranged when making material come off lower supporting plate 2, do level throw motion because lower supporting plate 2 is circular arc and tangent with horizontal plane.High wind is blown into the selection by winnowing case from air intake vent 3 levels; Under the acting in conjunction of wind-force and gravity; Can produce the displacement of differing in size in the horizontal direction in the different material dropping process of density or granularity, the horizontal displacement of the material that density is big or granularity is big is little, and the horizontal displacement of the material that density is little or granularity is little is big; Under the interception that cuts flitch 4, fall into three horizontal different aggregate bins 5 respectively, realized the sorting of material by density or granularity.
Wind receives the barrier effect of skewback 7, produces to stream to converge to exhaust outlet 8 discharges.Interception net 6 will be tackled by the dust that wind carries, and dust slips in the terminal aggregate bin 5 along skewback 7, has reduced the loss of material, and dustproof effect is arranged simultaneously.Whole device is prevented to produce dust polluting environment in the production process by box plate 9 sealings, has improved working environment.
