Description
Technical Field
[0001] This utility model relates to the technical field of Chinese medicinal material processing equipment, specifically a raw material impurity removal and screening device for processing Chinese medicinal materials. Background Technology
[0002] In the field of primary processing and pretreatment of Chinese medicinal materials, impurity removal and screening is the first key step to ensure the purity, safety and subsequent processing quality of medicinal materials. The impurities mixed in the raw materials mainly include: (1) non-medicinal parts with a relatively light specific gravity, such as stems, leaves, hairs and dust; (2) ferromagnetic metallic foreign objects, such as agricultural machinery parts and nails; (3) blocky impurities with a specific gravity similar to that of the medicinal materials but with a large size difference, such as soil lumps, gravel and other plant residues.
[0003] Currently, the industry generally adopts a segmented, equipment-based approach to remove the aforementioned different types of impurities. This involves using air separation equipment to separate light impurities, followed by magnetic separation equipment to adsorb and remove ferromagnetic metals, and finally, screening equipment using sieves of different apertures to separate the medicinal materials from impurities of varying sizes and perform preliminary grading.
[0004] In practice, several shortcomings exist. For example, the process flow is fragmented; the three types of equipment are typically arranged as independent units, requiring multiple feeding, transfer, and collection processes between them. This process is not only labor-intensive and inefficient, but also prone to cross-contamination from dust and material spillage during transport. Furthermore, each independent piece of equipment requires its own power system, support structure, and operating space, resulting in a lengthy production line layout, large footprint, and high overall energy consumption. Equipment parameters (such as airflow, magnetic strength, and screen amplitude) often need to be manually adjusted based on experience, lacking an intelligent control mechanism that coordinates with the real-time material status, making it difficult to optimize and stabilize the processing effect.
[0005] Now, a novel raw material impurity removal and screening device for processing Chinese medicinal materials is proposed to solve the above problems. Utility Model Content

A dust suction port is fixedly connected to the bottom of the left side of the main housing. A vacuum cleaner interface is fixedly connected to the left side of the dust suction port.
[0013] As a further technical solution of this utility model, the main shell, the negative pressure air inlet, and the collection cylinder are internally connected, and the outer diameter of the large-aperture mesh plate and the dust removal filter is consistent with the inner diameter of the collection cylinder.
[0014] As a further technical solution of this utility model, the main housing and the dust suction port are internally connected, and the PLC controller and the negative pressure fan are electrically connected.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the raw material impurity removal and screening device for processing Chinese medicinal materials not only realizes the function of improving the efficiency of process integration, but also realizes the function of simultaneous dust removal and feeding monitoring; Equipped with a cleanup component, the lumpy Chinese medicinal materials are fed into the inlet. The geared motor drives the magnetic separator roller to rotate at a constant speed, and the conveyor belt continuously transports the material to the left.

Equipped with a dust removal component, during use, the magnetically separated Chinese medicinal herbs fall through the side of the negative pressure suction port. The negative pressure fan continuously discharges air from the collection cylinder, creating a negative pressure inside the collection cylinder. This creates suction at the negative pressure suction port, drawing in air from inside the main housing along with lightweight materials such as dust, lint, and leaves from the falling material. A large-aperture mesh plate blocks large impurities such as leaves and straw, preventing damage to the negative pressure fan. The dust filter blocks dust, and the dust and impurities can be discharged by periodically opening the sealing cover. This step is called air separation.

[0021] The dust removal assembly 5 includes a negative pressure suction port 501, which is welded and fixed to the left side of the main housing 1. A collection cylinder 502 is connected to the left flange of the negative pressure suction port 501.

A negative pressure fan 505 is connected to the top flange of the collection cylinder 502. A sealing cap 506 is threaded to the bottom of the collection cylinder 502. A dust suction port 507 is fixedly connected to the bottom of the left side of the main housing 1. A vacuum cleaner interface 508 is fixedly connected to the left side of the dust suction port 507. The main housing 1, negative pressure air intake 501, and collection cylinder 502 are internally connected. The outer diameter of the large-aperture mesh plate 503 and the dust removal filter 504 are the same as the inner diameter of the collection cylinder 502. The main housing 1 and dust intake 507 are internally connected. The PLC controller 2 and negative pressure fan 505 are electrically connected. Air separation and dust removal are carried out simultaneously. Specifically, such as Figure 1 and Figure 4As shown, the negative pressure fan 505 continuously discharges air from the collection cylinder 502, creating a negative pressure inside the collection cylinder 502. This generates suction at the negative pressure suction port 501, drawing air from inside the main housing 1, along with lightweight materials such as dust, lint, and leaves from the falling materials, into the collection cylinder 502. The large-aperture mesh plate 503 blocks large impurities such as leaves and straw, preventing damage to the negative pressure fan 505. The dust filter 504 blocks dust. By periodically opening the sealing cover 506, dust and impurities can be discharged. This step is called air separation. The filtered dust falls to the bottom of the main housing 1.

After turning on the vacuum cleaner, the dust inside the equipment enters through the suction port 507, making cleaning convenient.

Specifically, such as Figure 1 and Figure 2 As shown, a CCD camera module 602 is installed on the concave frame 601 at the top of the feeding enclosure 7. By continuously collecting image information of the material below and uploading it to the background, combined with visual inspection and robot recognition, different types of medicinal materials can be identified, thereby controlling the actual power and parameters of magnetic separation, air separation and screening.
[0023] Working Principle: In use, the block-shaped Chinese medicinal materials are first fed into the feed inlet 8. The reduction motor 307 drives the magnetic separator roller 301 to rotate at a constant speed, and the conveyor belt 303 continuously conveys the material to the left. Under the action of inertia and gravity, the medicinal materials fall downwards. Ferromagnetic metals such as iron wire are attracted by the magnetic separator roller 301 and continue to move to the right. After leaving the magnetic field, they fall onto the receiving guide hopper 304 and are discharged outwards. During the fall of the magnetically separated Chinese medicinal materials, they pass by the side of the negative pressure suction port 501. The negative pressure fan 505 continuously discharges the air inside the collection cylinder 502, thus forming a negative pressure inside the collection cylinder 502. The negative pressure suction port 501 generates suction, which draws in the air inside the main shell 1 along with light materials such as dust, lint, and leaves from the falling material. Inside the collection cylinder 502, a large-aperture mesh plate 503 blocks large impurities such as leaves and straw, preventing damage to the negative pressure fan 505. The dust filter 504 blocks dust. Dust and impurities can be discharged by periodically opening the sealing cover 506. This step is air separation. Under the guidance of the guide plate 311, the material falls onto the screen 306 inside the screen frame 305. The vibrating motor 308 drives the screen frame 305 to vibrate continuously, screening out the broken materials in the Chinese medicinal materials. The screened dust falls to the bottom of the main housing 1. The industrial vacuum cleaner is periodically connected to the vacuum cleaner interface 508. After the vacuum cleaner is turned on, the dust inside the equipment enters along the suction port 507, making cleaning convenient. Complete block materials are discharged from one side. One machine completes magnetic separation, air separation and screening, with high integration and low labor intensity. The block-shaped Chinese medicinal materials are fed into the feed inlet 8. The feed enclosure 7 can restrict the position of the materials. The concave frame 601 on top of the enclosure is equipped with a CCD camera module 602. By continuously collecting image information of the materials below and uploading it to the background, combined with visual inspection and robot recognition, different types of medicinal materials can be identified, thereby controlling the actual power and parameters of magnetic separation, air separation and screening.
