Technical Field

The invention relates to the technical field of screening equipment, in particular to a screening device.

Background

Disclosure of Invention

In view of this, the present invention is directed to a screening device to improve the screening effect of materials.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

a screening device comprising:

the screening barrel is internally provided with a containing cavity, at least one screening unit which can rotate under the drive of external force is arranged in the containing cavity, and the containing cavity is divided into at least two screening cavities by the screening unit; a feed inlet for feeding materials into the containing cavity is formed in the top of the screening barrel, discharge ports are formed in the peripheral wall of the screening barrel corresponding to the screening cavities respectively, and the materials penetrate through the screening unit from top to bottom and are intercepted in the corresponding screening cavities;

the material guide plate corresponds to the rotating path of the material, is arranged on the inner wall surface of the shell, and extends into the containing cavity to guide the material out of the discharge hole.

Furthermore, the cavity where the screening unit is located is provided with a space for the screening unit to rotate in the cavity in a sealed mode.

Further, the screening unit comprises a screening body capable of rotating around the axis of the screening body.

Furthermore, the screening body is a screening net or a screening plate or a screening frame with screening holes.

Furthermore, annular bulges which are respectively arranged on two sides of the screening unit are arranged on the inner wall surface of the containing cavity, and a plurality of rolling parts are arranged between the annular bulges and the screening unit.

Furthermore, an outer frame is arranged on the peripheral wall of the sieve body, and a sealing body is arranged on the peripheral wall of the outer frame to limit the materials from falling downwards between the outer frame and the inner wall surface of the accommodating cavity.

Further, the outer frame is higher than the sieve body.

Furthermore, the guide plate is arranged on the peripheral wall of the screening barrel in a pivoting mode corresponding to the discharge port, and the guide plate can rotate under the driving of external force so as to lead the materials out of the screening cavity.

Furthermore, the sieve body is provided with a concave part which is positioned in the middle of the sieve body and is arranged in a concave mode, and a blanking port is arranged at the bottom of the concave part.

Compared with the prior art, the invention has the following advantages:

(1) according to the screening device, the screening units are arranged in the screening barrel in a rotating mode, when materials flow through the screening units, the materials with large grain sizes can be retained in the corresponding screening cavities due to interception of the screening units, the materials with small grain sizes pass through the screening units to enter the next screening cavity, and the screened materials are discharged out of the screening barrel through the discharge port after being guided by the guide plate, so that the materials are screened.

(2) The cavity and the screening unit are in a rotary body shape, so that the rotary arrangement of the screening unit is facilitated, the cavity can be well separated by the screening unit, and good conditions are created for screening materials.

(3) The screening body is adopted for filtering, so that the preset screening effect can be achieved, and the rotation of the screening body is facilitated.

(4) Screening net, screening board or screening frame all have the mature advantage of structure, can realize the screening to different grade type materials.

(5) Through setting up annular protrusion and rolling member, can increase the bearing capacity of casing to the screening unit, simultaneously, adopt rolling friction to increase the steadiness to effectively reduce the frictional force of screening unit in rotatory in-process.

(6) Set up the seal and do benefit to the leakproofness that improves the outline at rotatory in-process and hold the intracavity portion within a definite time, and then improve the screening effect to the material.

(7) The outer frame is higher than the setting of the screening body, prevents the run-out of material, reduces the chance that the material card is between the screening body and the container internal face to reduce the accident rate, do benefit to and improve life, increase material screening time simultaneously.

(8) The screening body of the curved surface structure is adopted, materials in the corresponding screening cavity can be screened on the screening body by means of centrifugal force, the materials flow to the periphery, and the materials are discharged from the screening cavity.

(9) Screening to the same but different material of weight of size fraction can be realized through setting up the depressed part to separate the material.
