Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, specifically to a high-efficiency device for separating and screening impurities in the purification of traditional Chinese medicine decoction pieces. Background Technology

[0002] The core objective of cleaning Chinese medicinal herbs is to remove non-medicinal parts, mud, dust, foreign matter, and other impurities from the herbs to ensure that the quality of the herbs meets the pharmacopoeia standards.

[0003] Utility model patent CN219540982U discloses a portable traditional Chinese medicine separation and screening device. This device mainly consists of a shell, a box, an outer shell, a second motor, a circular plate, a third filter, a baffle, a straight cylinder, a horizontal bar, an inclined plate, a square box, a vertical plate, a curved rod, a circular block, and a screening structure. The box is fixedly connected to one side of the top of the device, and the outer shell is fixedly connected to the other side. The second motor is installed on the upper inner wall of the outer shell. Through the coordinated action of the shell, circular plate, box, and third filter, the first filter shakes under force, effectively filtering out impurities such as stones from the traditional Chinese medicine. After being filtered by the first filter, the traditional Chinese medicine enters the box through a guide. The fan starts working, blowing any light impurities not filtered by the first filter into the inclined cylinder, where they then fall into the shell. Simultaneously, the traditional Chinese medicine smoothly enters the other side of the shell under gravity, thus improving the screening effect and preventing the carryover of impurities.

[0004] However, the fine particles such as mud and dust generated during the screening process of this existing technology are easily stirred up, forming dust. This not only endangers the health of operators and leads to substandard workshop environments, but also causes dust to re-adhere to the medicinal slices or mix into the impurity collection stage, affecting the purification effect. At the same time, different types and specifications of medicinal materials require significantly different screen mesh sizes, and replacing the screens of traditional equipment usually requires the disassembly of multiple parts with special tools. The process is cumbersome and time-consuming, making it difficult to quickly adapt to the production needs of multiple varieties and specifications of medicinal materials, thus limiting the versatility and production flexibility of the equipment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides the following technical solution: A high-efficiency device for separating and screening impurities in the purification of traditional Chinese medicine decoction pieces, comprising a support section, a conveying section, and a screening section. The support section includes a supporting screening shell, which is fixedly mounted on a support base plate. A discharge trough is provided at the bottom of the supporting screening shell. A supporting feed hopper for feeding is fixedly mounted at one end of the supporting screening shell, and a supporting discharge shell and a supporting pipe for discharging are detachably mounted at the other end of the supporting screening shell via supporting fastening bolts. The conveying section includes a conveying shaft rotatably mounted within the support section. A conveying screw for conveying materials and a conveying push rod for stirring materials are fixedly mounted on the conveying shaft. The conveying push rod cooperates with the conveying discharge screen to screen impurities in the materials. The screening section includes a screening funnel fixedly mounted on the support base plate, which is located below the discharge trough.

[0006] Furthermore, a conveyor flywheel is fixedly mounted on the conveyor shaft, and the conveyor flywheel is mounted on the output shaft of the conveyor motor via a conveyor belt. The conveyor motor is fixedly mounted on the support base plate.

[0007] Furthermore, the screening funnel is provided with a screening air inlet chamber and a screening air inlet pipe. The screening air inlet chamber is provided with ventilation holes. The other end of the screening air inlet pipe is provided on the screening discharge box. Multiple screening filters are provided in the screening discharge box. Screening fan blades are rotatably provided on one side of the screening filter. The screening fan blades are fixedly provided on the output shaft of the screening motor.

[0008] Furthermore, a screening fixing plate is rotatably mounted on the screening discharge box, and a sealing gasket is provided between the screening fixing plate and the screening discharge box.

[0009] Furthermore, both ends of the conveying screen are provided with mounting holes, which are detachably installed inside the supporting screening housing by mounting bolts.

[0010] Furthermore, a support cover plate is rotatably mounted on the supporting screening shell, a support fixing plate is fixedly mounted on the support cover plate, a support fixing plate is fixedly mounted on the supporting screening shell, a support fastening plate is rotatably mounted on the support fixing plate, a support spring is provided between the support fastening plate and the support fixing plate, and a support fastening ring is rotatably mounted on the support fixing plate. The support fastening ring cooperates with the groove on the support fixing plate to fix the supporting cover plate.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. Dust circulation filtration: Driven by a screening motor, axial flow fan blades form a directional airflow within the supporting screening housing. Fine particles such as mud, sand, and dust raised during screening are drawn into the screening air intake pipe and filtered through a multi-layer synthetic fiber filter screen in the screening discharge box. This effectively captures airborne dust, solving the health hazards to operators and substandard workshop environment caused by dust in traditional equipment. It also prevents dust from re-attaching to the medicinal slices or mixing into the impurity collection process, thus improving the purification effect.

[0013] 2. Optimized airflow path: Air is drawn in from the bottom of the support feed hopper and screening funnel, as well as the screening air inlet chamber, forming a three-dimensional airflow circulation to ensure that dust is captured without dead angles. The filtered clean air is discharged from the bottom of the screening discharge box, realizing closed-loop control of dust treatment.

[0014] 3. Quick-release structure design: The supporting screening shell is detachably connected to the supporting discharge shell and supporting pipe via supporting fastening bolts. When changing the screen, simply unscrew the bolts to disassemble the entire discharge end component and directly remove the conveyor screen. The screen is fixed at both ends by mounting holes and bolts, eliminating the need for specialized tools. A single person can complete disassembly and installation quickly, significantly reducing screen change time and meeting the rapid switching needs of various types and specifications of medicinal materials. Furthermore, different mesh sizes can be flexibly changed according to the type of medicinal material (roots, leaves, fruits, etc.) and specifications, avoiding the lack of versatility caused by the cumbersome screen fixing in traditional equipment. This significantly improves the equipment's adaptability to diverse production tasks, reducing equipment investment costs and production management difficulties for enterprises.

[0031] like Figures 1 to 10 As shown, the present invention discloses a high-efficiency device for separating and screening impurities in the purification of traditional Chinese medicine decoction pieces. Its working principle is as follows:

[0032] The Chinese herbal medicine slices to be screened are fed into the device through the supporting feed hopper 307. The conveyor motor 101 is turned on, and the rotation of the conveyor motor 101 drives the conveyor flywheel 103 to rotate via the conveyor belt 102. The rotation of the conveyor flywheel 103 drives the conveyor shaft 104 to rotate, which in turn drives the conveyor screw feeding shaft 105 and the conveyor push rod 106 to rotate. The rotation of the conveyor screw feeding shaft 105 feeds the Chinese herbal medicine slices into the conveyor discharge screen 107. The rotating conveyor push rod 106 causes the Chinese herbal medicine slices in the conveyor discharge screen 107 to rotate. During this process, non-medicinal parts of the Chinese herbal medicine, mud, dust, foreign objects, and other small impurities are screened out through the screening holes on the conveyor discharge screen 107. Under the action of gravity, they fall from the discharge chute at the bottom of the supporting screening shell 312 into the screening funnel 201, and are finally discharged from the bottom of the screening funnel 201 for collection. During this process, the screening motor 206 is turned on, and the rotation of the screening motor 206 drives the screening fan blades 207 to rotate. The rotation of the screening fan blades 207 drives air from the supporting feed hopper 307 into the supporting screening housing 312. The air containing dust inside the supporting screening housing 312 enters the screening air inlet pipe 203 from the top of the screening funnel 201. At the same time, the air around the equipment enters the screening air inlet pipe 203 from the bottom of the screening funnel 201 and the screening air inlet chamber 202. At this time, the dust generated by the falling small-volume mud, sand, dust and other particles is drawn into the screening air inlet pipe 203 with the air, and finally enters the screening discharge box 204 through the screening air inlet pipe 203. After being filtered layer by layer by the screening filter screen 205, it is discharged from the bottom of the screening discharge box 204. The screening filter screen 205 is made of synthetic fiber filter cotton and is used to filter the dust in the air, which solves the problem of dust flying in the traditional impurity treatment process.

[0033] After being screened by the conveyor screen 107, the Chinese herbal medicine pieces are discharged from the end of the conveyor screen 107 into the supporting discharge shell 309, and finally fall into the collection device from the supporting pipe 310 under the action of gravity, thus completing the impurity treatment of the Chinese herbal medicine pieces.

[0034] During the screening process, depending on the type and specifications of the medicinal materials, the supporting fastening bolts 311 can be removed, and then the supporting discharge shell 309 and supporting pipe 310 can be removed from the supporting screening shell 312. The conveying discharge screen 107 can be replaced with a specification suitable for drug screening, thereby improving the practicality and applicability of the equipment, which is suitable for screening and removing impurities from different types of drugs.

[0035] When maintaining the equipment, the operator rotates the support fastening plate 303, causing the support fastening plate 303 to drive the support fastening ring 304 out of contact with the support fixing plate 302. Then, the support cover plate 301 is flipped over to maintain the inside of the support screening shell 312. The operation is convenient and easy.
