The first homogenizing plate assembly is that each first short slab forms, and the incline direction of the layout that is parallel to each other between each first short slab and each first short slab is consistent, and the 3rd vacancy portion between each first short slab forms the first ore in sand form outlet.
The increase gradually that the first ore in sand form outlet is offered along tape transport direction.
The second current-sharing assembly is that filter forms, and the wire side of filter is arranged perpendicular to the compass screen surface of screen cloth.
The second current-sharing assembly is that plate body forms, and the incline direction that the second current-sharing assembly arranges is contrary with the incline direction of the first homogenizing plate assembly.
The second current-sharing assembly is that the second batten forms, and the second batten is offered the second vacancy portion along the long direction interval of plate, and this second vacancy portion is the first ore in sand form outlet.
The second current-sharing assembly is that each second short slab forms, and the incline direction of the layout that is parallel to each other between each second short slab and each second short slab is consistent, and the 4th vacancy portion between each second short slab forms the second ore in sand form outlet.
First and second ore in sand form outlet arranges along the groove width direction interval of distributing trough.
By the first homogenizing plate assembly is set, make like this ore in sand form of exporting from conveyer belt to be uniformly distributed at screen cloth, improve screening effect and screen rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of two kinds of embodiments of the present invention.
The specific embodiment
In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The technical scheme that the present invention takes is, as shown in Figure 1, a kind of ore in sand form screening plant, comprise the conveyer belt 20 for feeding intake to screening machine and the screen cloth 11 that carries out ore in sand form screening, screen cloth 11 is fixed in frame 10, screen cloth 11 is skewed layout, the upper end of screen cloth 11 is provided with distributing trough 12, distributing trough 12 be skewed layout and and screen cloth 11 layout that postpones, the corresponding layout of discharge end of distributing trough 12 and conveyer belt 20, the throughput direction of conveyer belt 20 and the interior material flow of screen cloth 11 send direction intersect or be arranged vertically, on the bottom land of distributing trough 12, be provided with the first homogenizing plate assembly 13 that conveyer belt 20 output ores in sand form are evenly arranged on screen cloth 11, the first homogenizing plate assembly 13 is along the width range setting of screen cloth 11, the perpendicular layout of bottom land of the plate face of the first homogenizing plate assembly 13 and distributing trough 12, the first homogenizing plate assembly 13 is the incline direction of skewed layout and the first homogenizing plate assembly 13 and the incline direction of screen cloth 11 (compass screen surface 11a) is crossing or vertical, the first homogenizing plate assembly 13 is greater than the height of the other end near the height of conveyer belt 20 one end, length direction along the first homogenizing plate assembly 13 on the first homogenizing plate assembly 13 is evenly provided with the first ore in sand form outlet 131.By the first homogenizing plate assembly 13 is set, from change traditional scheme, ore in sand form can only distribute from the screen cloth 11 compass screen surface 11a near conveyer belt 20 outlet one sides, the setting of the first homogenizing plate assembly 13 can, so that the ore in sand form flowing out from conveyer belt 20 is uniformly distributed along the width range of screen cloth 11, improve screening effect and screen rate.During operation, the first homogenizing plate assembly 13 can be on distributing trough 12 bottom lands along the width range setting of groove width.
The first homogenizing plate assembly 13 is set separately, ore in sand form distributing homogeneity or limited, therefore, in the present invention, the downside of the first homogenizing plate assembly 13 is provided with the second current-sharing assembly 14, the scope that the second current-sharing assembly 14 arranges is consistent with the first homogenizing plate assembly 13, and the length direction along the second current-sharing assembly 14 on the second current-sharing assembly 14 is evenly provided with the second ore in sand form outlet 141.Current-sharing distribution effect in the time of by the first homogenizing plate assembly 13 and the second current-sharing assembly 14, therefore can, so that current-sharing is better evenly, better improve screening effect and screen rate.
The first homogenizing plate assembly 13 can be implemented according to following two kinds of embodiments, and one is: the first homogenizing plate assembly 13 is that the first batten forms, and the first batten is offered the first vacancy portion along the long direction interval of plate, and this first vacancy portion forms the first ore in sand form outlet 131.
It two is: the first homogenizing plate assembly 13 is for each first short slab forms, between each first short slab, be parallel to each other arrange and the incline direction of each first short slab consistent, the 3rd vacancy portion between each first short slab forms the first ore in sand form outlet 131.
More preferably, the first ore in sand form outlet 131 increases gradually of offering along conveyer belt 20 throughput directions.So more be conducive to being uniformly distributed of ore in sand form.
For the second current-sharing assembly 14, it also can be plate body and forms, and the incline direction that the second current-sharing assembly 14 arranges is contrary with the incline direction of the first homogenizing plate assembly 13.Concrete can implement according to the embodiment identical with the first homogenizing plate assembly 13, that is, one is: the second current-sharing assembly 14 is that the second batten forms, and the second batten is offered the second vacancy portion along the long direction interval of plate, and this second vacancy portion is the first ore in sand form outlet 131.
It two is: the second current-sharing assembly 14 is for each second short slab forms, between each second short slab, be parallel to each other arrange and the incline direction of each second short slab consistent, the 4th vacancy portion between each second short slab forms the second ore in sand form outlet 141.
Highly preferredly be, the second current-sharing assembly 14 adopts filters to form, and the wire side of filter is arranged perpendicular to the compass screen surface 11a of screen cloth 11.The effect like this distributing homogeneity of ore in sand form being improved is best.
In addition, if adopt plate body to form the second current-sharing assembly 14, preferably by first and second ore in sand form outlet, the groove width direction interval along distributing trough 12 arranges, to obtain best distribution effect.
By the first homogenizing plate assembly 13 is set, make like this can be uniformly distributed at screen cloth 11 from the ore in sand form of conveyer belt 20 outputs, improve screening effect and screen rate.
In a word, screening plant provided by the invention, can effectively realize the Transport Rate that improves ore in sand form between conveyor belt 20, prevents from that ore in sand form is unrestrained to cause all inconvenience.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
