Description

Technical Field

[0001] This utility model belongs to the field of tea processing equipment, specifically relating to a de-stoned air separator. Background Technology

[0002] In the field of tea processing, efficiently removing heavy impurities such as stones from raw materials (de-stonening) is crucial for ensuring the quality of the finished tea product. Air separation, with its high efficiency and low damage, is currently the mainstream physical de-stonening method. However, traditional air separation equipment often faces problems in practical applications, such as loose structure, large footprint, uneven airflow distribution leading to poor sorting accuracy, and dust diffusion during the impurity removal process polluting the environment and the product. Therefore, designing a new de-stonening air separator is particularly necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a de-stoned air separator to solve the problems of poor sorting accuracy and dust pollution in the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a destoning air separator, comprising a frame, a fan assembly, an electromagnetic feeding assembly, a dust cover, an air deflector adjustment assembly, a negative pressure dust removal system, and a discharge port;

[0005] A cover plate is fixed to the top of the frame. The upper half of the frame is divided into two parts by a longitudinal connecting partition: one side is the fan installation chamber and the other side is the air classifier chamber. The electromagnetic feeding assembly and dust cover are installed on the cover plate and are located near the fan installation chamber. One end of the electromagnetic feeding assembly is located inside the dust cover. A discharge port is provided on the cover plate inside the dust cover.

[0006] The fan assembly is located in the fan installation chamber, and its air outlet is connected to the front end of the air classifier chamber via an air guide pipe; the air classifier chamber has side plates A on two symmetrical sides, and the other side is connected to the negative pressure dust removal system; the air plate adjustment assembly is located in the air classifier chamber, and there is a discharge port below the air classifier chamber.

[0007] Furthermore, the wind vane adjustment assembly includes two symmetrically arranged hinge plates, a rocker arm, a connecting rod, a fixed plate, and an adjustment plate; the hinge plates are provided with arc-shaped grooves, and the rocker arm is slidably mounted on the arc-shaped grooves by locking screws; a connecting rod connects the two rocker arms, a fixed plate is fixedly mounted on the connecting rod, and an adjustment plate is slidably mounted on the fixed plate.

[0008] Furthermore, two grooves are provided on the adjusting plate, and bolts pass through the grooves to connect the fixing plate to the adjusting plate.

[0009] Furthermore, there are two sets of air deflector adjustment components, which divide the air separation chamber into three areas, and the angle between the adjustment plates of the two sets of air deflector adjustment components is adjustable from 30° to 150°.

[0010] Furthermore, the negative pressure dust removal system includes a dust collection port, a dust removal duct, and a filter device connected in sequence, with the dust collection port connected to the airflow channel at the end of the air separation chamber.

[0011] Furthermore, there are three discharge ports, all located below the air classifier chamber, with their ends extending into the interior of the air classifier chamber; and the positions of the three discharge ports correspond one-to-one with the three air ducts formed by the air plate adjustment assembly.

[0012] Furthermore, an observation window is provided on side panel A.

[0013] This invention completes the tea leaf air separation process through electromagnetic vibration feeding assembly, airflow generation and guidance, air separation, negative pressure dust removal, and discharge. It has a compact structure and a high stone removal rate.

[0014] By setting up an air deflector adjustment component, the air deflector can be infinitely adjusted from 30° to 150° and precisely positioned in height, allowing airflow to penetrate the material evenly. Stones, due to their large mass, are discharged near the first outlet in the fan installation chamber, while lighter tea leaves drift to subsequent outlets, improving sorting accuracy. A closed-loop dust collection system, consisting of a dust hood and a negative pressure dust removal system, reduces dust escape rate. Attached Figure Description
