Abstract

The utility model provides a vibrating screen comprising a screen box (1), a bracket (2), a feed bin (3) and a discharge bin (4), wherein an included angle alpha is formed between the screen plate of the screen box (1) and the horizontal plane; the range of the included angle alpha is 8-15 degrees; and the mesh diameter of the screen plate of the screen box (1) is increased by 5%-20%. The inclined angle of the screen plate of the vibrating screen is increased, the top-bottom difference of the screen plate is improved further, the flowability of feedstuff inside the screen box is improved, the screened feedstuff particles are uniform and the content of the powder feedstuff is lowered greatly.

Description

Vibratory sieve

Technical field

The utility model relates to mechanical field, relates in particular to a kind of vibratory sieve.

Background technology

Vibratory sieve is widely used in all conglomeraties such as mineral screening, production of fodder as a kind of equipment that screens material.In the production of fodder industry,, usually production of fodder is become nutty structure at present for the nutritional labeling that guarantees feed is difficult for running off.

The common screen tray of existing vibration separation screen is horizontal positioned or inclination certain angle α, the angle [alpha] that tilts is generally also in 5 °, this vibratory sieve is little owing to the screen tray angle of inclination when screening material, make that the drop up and down of screen tray is little, sieve in the process at screen tray, pellet illiquidity in the screen box, cause the less or pulverous feed of screen box endoparticle not screen, thereby make that the feed granules that comprises in the finished product feedstuff is not of uniform size, and contain pulverous feed, cause client's satisfaction to descend.

The utility model content

The technical problems to be solved in the utility model is that a kind of even particle size, the difficult vibratory sieve that produces Powdered feed are provided.

Technical solution of the present utility model is, a kind of vibratory sieve is provided, and comprises screen box, support, feeding bin and goes out feed bin, forms angle α between the screen tray of described screen box and the horizontal plane, and the angular range of angle α is at 8 °～15 °.

After adopting above scheme, the angle of inclination of the screen tray of the utility model vibratory sieve is strengthened, and has further improved the drop up and down of screen tray, has improved the flowability of feed in the screen box, the feed granules of screening process screening will be more even, and can reduce the content of Powdered feed greatly.

As preferably, the angle that forms angle α between the screen tray of described screen box and the horizontal plane is 10 °.

As improvement, the aperture of the sieve aperture of the screen tray of described screen box increases 5%～20%.Filter the content that also can effectively reduce Powdered feed down by the feed that the aperture that increases the screen tray sieve aperture can be less with particle.

As preferably, the aperture of the sieve aperture of the screen tray of described screen box increases 8%.

Description of drawings

It in the accompanying drawing structural representation of the utility model vibratory sieve.

Shown in the figure:

1, screen box, 2, support, 3, feeding bin, 4, go out feed bin.

The specific embodiment

The specific embodiment of the present utility model is described in detail the technical solution of the utility model for better illustrating below in conjunction with accompanying drawing.

As shown in the drawing, a kind of vibratory sieve comprises screen box 1, support 2, feeding bin 3 and goes out feed bin 4, forms angle α between the screen tray of described screen box 1 and the horizontal plane, the angle of angle α is 10 °, and the aperture more too much than original powder, the aperture of the sieve aperture of the screen tray of described screen box 1 increases 8%.

In the above-described embodiments, a kind of preferred forms of the utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of changes and improvements, angle α as described can be at the unspecified angle between 8 ° and 15 °, and the aperture of the sieve aperture of the screen tray of and for example described screen box 1 is also at the unspecified angle that depending on the circumstances or the needs of the situation increases between 5%～20%.At this, should illustrate that any change of being made all will fall in the protection domain of the present utility model under inventive concept of the present utility model.

Claims

1. a vibratory sieve comprises screen box (1), support (2), feeding bin (3) and goes out feed bin (4), it is characterized in that: form angle α between the screen tray of described screen box (1) and the horizontal plane, the angular range of angle α is at 8 °～15 °.

2. vibratory sieve according to claim 1 is characterized in that: the angle that forms angle α between the screen tray of described screen box (1) and the horizontal plane is 10 °.
