Description

Technical Field

[0001] This utility model belongs to the field of air classifier technology, and more specifically, it relates to a multi-stage air classifier. Background Technology

[0002] An air classifier (also known as an air classifier or air separator) is a mechanical device that uses the differences in aerodynamic characteristics generated by airflow to automatically classify and remove impurities from solid bulk materials according to density, particle size, or shape.

[0003] Based on existing technology, it has been found that existing air classifiers only screen materials of the same type and similar size and quality. If there are agglomerated materials during feeding, the blower alone is insufficient to separate the agglomerated materials, as there is no corresponding crushing structure. Furthermore, in existing air classifiers, lighter impurities adhere to heavier materials during separation, making them difficult to separate, resulting in poor separation effect and failing to enhance screening efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a multi-stage air classifier. This solves the problem that existing air classifiers, when used, struggle to separate clumps of material during feeding if the fan alone is insufficient, lacking a corresponding crushing structure. Furthermore, existing air classifiers often result in lighter impurities adhering to heavier materials during separation, leading to poor separation efficiency and hindering the enhancement of screening effectiveness.

[0015] The control motor is fixedly installed inside the bottom of the main body; a rotating component is provided on the output shaft of the control motor.

[0016] Furthermore, the vibration mechanism includes: a mounting rod and a base rod;

[0017] The mounting rod is located at the bottom of the main body; the bottom rod is slidably mounted on the top of the mounting rod; the bottom of the bottom rod is connected to the bottom of the main body by a spring.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this device, a rotating component and a contact component are provided. The rotating component is connected to the motor on the feeding component, while the contact component is fixedly set on the inner wall of the feeding component. Thus, when the material is added into the feeding component, some of the lumpy material comes into contact with the conical protrusions on the rotating component and the contact component, thereby achieving a preliminary crushing effect. Furthermore, the rotating component is controlled to rotate by the motor on the feeding component. By intersecting the rotating component and the contact component, the lumpy material can be crushed, ensuring the uniformity of the material.

[0022] 2. This device includes a centrifugal fan and a vibrating component. The centrifugal fan is located on the bottom right side of the main body, while the vibrating component is located inside the main body. During operation, the motor drives the rotating component to rotate, which in turn moves the vibrating component and the base rod on the mounting rod via the connecting handle, compressing the spring. The bottom of the vibrating component then contacts the mounting component, causing the vibrating component to vibrate and lift the material on top. This vibration effect shakes off light impurities adhering to the surface of the material. The centrifugal fan at the bottom of the main body blows the light impurities out through the discharge port on the bottom left side of the main body, while heavy impurities are discharged through the discharge port at the bottom of the main body, enhancing the screening effect.

[0044] The specific usage and function of this embodiment are as follows:

[0045] In this invention, when using the device, after the material is added into the feeding component 201, some of the clumped material comes into contact with the conical protrusions on the rotating component 203 and the contact component 202, thus achieving a preliminary crushing effect. The rotating component 203 is rotated by a motor on the feeding component 201. The rotating component 203 and the contact component 202 are arranged in a crisscross pattern, which crushes the clumped material, ensuring the uniformity of the material. After the material falls, the first centrifugal fan 1041 at the top of the main body 101 blows up light impurities, which fall onto the guide plate 103 and are collected by the external receiving and collecting device of the guide plate 103. Heavy materials fall onto the vibrating component 403, and... The control motor 301 drives the rotating part 302 to rotate, which in turn drives the vibrating part 403 and the bottom rod 402 to move on the mounting rod 401 through the connecting handle 404, and compresses the spring. Then, the bottom of the vibrating part 403 comes into contact with the mounting part 107, causing the mounting part 107 to impact the bottom of the vibrating part 403, causing the vibrating part 403 to vibrate and causing the material on top to bounce upward. Through the vibration effect, light impurities attached to the surface of the material can be shaken off. With the cooperation of the second centrifugal fan 1042 at the bottom of the main body 101, the light impurities are blown out from the discharge port on the left side of the bottom of the main body 101, while heavy impurities are discharged through the discharge port at the bottom of the main body 101, thus completing the screening of the same type of material.
