Description

Technical Field

[0001] This invention relates to a processing technology for Chinese medicinal materials, and more specifically, to a pre-treatment device for cleaning rhizomes and other types of Chinese medicinal materials. Background Technology

[0002] The mechanization level of Chinese medicinal herb processing is increasing, involving a series of processes such as cleaning, slicing, and drying. However, Chinese medicinal herbs are classified by source, including seeds and fruits, roots and rhizomes, herbs, and barks, with diverse forms, making it difficult to find a universally applicable processing equipment. Therefore, developing corresponding processing machinery for various herbs with common characteristics is key to improving processing efficiency and quality. For example, after cleaning, many non-medicinal parts such as rootlets, rough bark, and placenta remain in root and rhizome herbs. In traditional processing, these non-medicinal parts must be manually removed, resulting in high labor costs and low processing efficiency. Furthermore, some fresh herbs contain mucus on their surface, making it difficult to fix the herbs during slicing, resulting in poor slice shape. Friction also damages the surface, causing loss of active ingredients. Therefore, after cleaning, it is necessary to pre-treat the herbs before slicing and drying. Mechanized methods can quickly and easily remove non-medicinal parts and control surface moisture. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a pretreatment device for cleaning rhizomes and other medicinal materials. This device can treat the non-medicinal parts and dry the surface moisture of rhizomes and other medicinal materials after cleaning and before cutting and drying, which is beneficial to the subsequent processing of medicinal materials and improves processing efficiency and quality.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pretreatment device for cleaning root and rhizome Chinese medicinal materials, including a drum and a fixed cylinder, the drum being rotatably installed in the fixed cylinder, the inner wall of the drum being densely covered with a number of scrapers, scraping holes being provided on the drum wall corresponding to the scrapers, a hot air duct being installed inside the drum, and a number of air outlet holes being arranged on the hot air duct.

[0005] The cleaned rhizomes and other medicinal herbs are placed inside a drum. As the drum rotates, the herbs come into contact with and rub against scrapers on the inner wall. The scrapers remove non-medicinal parts such as residual stems, rough bark, and placenta from the surface of the herbs, which are then discharged through scraping holes outside the drum, achieving separation. A fixed cylinder collects these discharged non-medicinal parts. During operation, the device can be tilted to facilitate the movement and transport of the rhizomes and other medicinal herbs within the drum. Throughout the process, hot air is introduced into the hot air channel and discharged into the drum through air outlets, removing moisture from the surface of the rhizomes and other medicinal herbs. This drying process, while removing non-medicinal parts, also dries the surface of the herbs, which is beneficial for subsequent processing.

[0006] The pretreatment device for cleaning rhizomes of Chinese medicinal materials of the present invention can treat non-medicinal parts and dry surface moisture of rhizomes of Chinese medicinal materials after cleaning and before cutting and drying, which is beneficial to the subsequent processing of medicinal materials and improves processing efficiency and quality.

[0007] Preferably, an inner spiral blade is installed on the inner wall of the drum, and an outer spiral blade is installed on the outer wall of the drum.

[0008] As the inner and outer spiral blades rotate together with the drum, they facilitate the transport of root and rhizome-type Chinese medicinal materials inside the drum, as well as the transport of non-medicinal parts scraped off between the drum and the fixed cylinder.

[0009] Preferably, a feed cover is installed at the front end of the fixed cylinder, and a discharge cover is installed at the rear end of the fixed cylinder. The feed cover has a feed port that communicates with the front end of the roller, and the discharge cover has a discharge port that communicates with the rear end of the roller.

[0010] The installation of the feed cover and discharge cover facilitates the setting of the feed port and discharge port.

[0011] Preferably, both the front and rear covers are provided with positioning grooves, and the front and rear ends of the roller are respectively fitted into the two positioning grooves, allowing the ends of the roller to rotate within the positioning grooves.

[0012] During the rotation of the drum, both ends rotate in two positioning grooves respectively, which is stable and reliable.

[0013] Preferably, a waste discharge port is provided at the lower rear end of the fixed cylinder.

[0014] The non-medicinal parts scraped off between the outer drum and the fixed drum are discharged out through the discharge port, thus separating them from the root and stem medicinal materials.

[0015] Preferably, a driven gear ring is provided on the roller, a drive motor is installed on the fixed cylinder, and a drive gear is installed on the output shaft of the drive motor. The drive gear meshes with the driven gear ring for transmission.

[0016] The drive motor operates and the rotation of the drum is achieved through the meshing of the drive gear and the driven gear ring, which is smooth and reliable.

[0017] Preferably, the blade edge of the scraper has an arc-shaped structure.

[0018] The curved edge of the blade is effective at scraping non-medicinal parts, and it is easy to remove the scraped non-medicinal parts through the scraping hole.

[0019] Preferably, a feed hopper is installed at the front end of the fixed cylinder, and a positioning cylinder is installed above the feed hopper. A centrifuge cylinder is rotatably installed inside the positioning cylinder. The centrifuge cylinder includes an inner cylinder and an outer cylinder. The inner cylinder can be raised and lowered and moved. A flip cover is installed at the lower end of the inner cylinder. A top rod is set below the flip cover inside the positioning cylinder. The inner cylinder moves downward so that the flip cover hits the top rod, thereby opening the flip cover. The inner cylinder sidewall is densely covered with drainage inner holes, and the outer cylinder sidewall is densely covered with drainage outer holes. The drainage inner holes and drainage outer holes are set one-to-one.

[0020] After cleaning, the root and rhizome medicinal materials are first placed in a centrifuge. The centrifuge's rotation centrifuges the materials, causing residual moisture to be expelled through the inner and outer drainage holes, achieving initial drying. Under centrifugal force, residual roots from the medicinal materials enter the drainage holes. After the centrifuge stops rotating, the inner cylinder moves downwards, causing the drainage holes to shift and cut off the remaining roots, achieving initial removal of residual roots. During the downward movement of the inner cylinder, the flap pushes against the top rod, opening the flap and allowing the root and rhizome medicinal materials to fall into the feed hopper. This initial centrifugation process, achieving preliminary drying and removal of residual roots, before the materials are placed into the drum, improves both the removal and drying efficiency of residual roots.

[0021] Preferably, the flap is hinged to the lower end of the inner cylinder, and a positioning torsion spring is installed between the flap and the inner cylinder to close the flap at the lower end of the inner cylinder; the flap extends outward near the hinge point with the inner cylinder to form a top joint, and the inner cylinder moves downward so that the top joint hits the top rod, thereby opening the flap.

[0022] The positioning torsion spring ensures that the flap can reliably close at the lower end of the inner cylinder, preventing the root and rhizome medicinal materials inside from falling down automatically. As the inner cylinder moves downward, the top part presses against the top rod, causing the flap to flip downward, thus opening the lower end of the inner cylinder and facilitating the falling of the root and rhizome medicinal materials into the feed hopper.

[0023] Preferably, the upper end of the outer cylinder is provided with several sliding grooves, and the upper end of the inner cylinder is equipped with a rotatable limiting ring. The lower end of the limiting ring and the sliding groove are provided with support blocks. The rotation of the limiting ring causes the support blocks to slide into the sliding grooves or be supported on the upper end of the outer cylinder.

[0024] The limiting ring enables the inner cylinder to be supported and positioned. When the support block supports the upper end of the outer cylinder, the inner and outer drainage holes are aligned. During the process of the support block sliding into the groove, the inner and outer drainage holes are misaligned.

[0025] Compared with the prior art, the beneficial effects of the present invention are: (1) The pretreatment device for cleaning rhizomes of Chinese medicinal materials of the present invention can treat non-medicinal parts and dry surface moisture of rhizomes of Chinese medicinal materials after cleaning and before cutting and drying, which is beneficial to the later processing of medicinal materials and improves processing efficiency and processing quality; (2) After the rhizomes of Chinese medicinal materials are centrifuged in a centrifuge, the preliminary drying and preliminary removal of residual roots are achieved, and then they are loaded into a drum, which is beneficial to improve the removal effect and drying effect of residual roots of rhizomes of Chinese medicinal materials.

Detailed Implementation

[0029] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Example 1: A pretreatment device for cleaning rhizomes and other medicinal herbs (see attached document) Figure 1 The device includes a roller 1 and a fixed cylinder 2, which are arranged horizontally. The roller is rotatably mounted inside the fixed cylinder. A gap is provided between the outer wall of the roller and the inner wall of the fixed cylinder. The inner wall of the roller is densely covered with several scrapers 3, all of which together form a fish-scale-like structure. Scraping holes 4 are provided on the roller wall corresponding to the scrapers. The edges of the scraper blades are arc-shaped, and the scraping holes are also arc-shaped. A hot air duct 5 is installed inside the roller, and the hot air duct is coaxially arranged with the roller. Several air outlet holes 6 are provided on the hot air duct.

[0031] An inner spiral blade 7 is installed on the inner wall of the drum, and an outer spiral blade 8 is installed on the outer wall of the drum. The inner and outer spiral blades rotate together with the drum to realize the conveying of root and rhizome Chinese medicinal materials inside the drum, as well as the conveying of non-medicinal parts scraped off between the drum and the fixed cylinder.

[0032] A feed cover 9 is installed at the front end of the fixed cylinder, and a hot air duct is fixedly installed on the feed cover. A discharge cover 10 is installed at the rear end of the fixed cylinder. The feed cover covers the front opening between the roller and the fixed cylinder, and the discharge cover covers the rear opening between the roller and the fixed cylinder. A feed inlet 11 connected to the front end of the roller is provided on the feed cover. A feed hopper 12 is installed at the front end of the fixed cylinder, and the lower end of the feed hopper is connected to the feed inlet. A discharge outlet 13 connected to the rear end of the roller is provided on the discharge cover. A waste discharge port 14 is provided at the lower rear end of the fixed cylinder. Positioning grooves 14 are provided on both the front and rear covers. The front and rear ends of the roller are respectively fitted into the two positioning grooves, and the ends of the roller can rotate in the positioning grooves.

[0033] A driven gear ring 15 is installed on the drum, and the driven gear ring is located on the outer front wall of the drum. A drive motor 16 is installed on the fixed cylinder, and a drive gear 17 is installed on the output shaft of the drive motor. The drive gear meshes with the driven gear ring for transmission. A clearance groove 18 is provided on the fixed cylinder corresponding to the drive gear. The drive gear passes through the clearance groove and meshes with the driven gear ring. Several support legs 19 are installed on the fixed cylinder to support the entire device.

[0034] In a circumferentially adjacent pair of scrapers, one row is arranged longitudinally and the other transversely. When the roller rotates and moves circumferentially relative to the rhizome-type medicinal materials, the longitudinally arranged scrapers achieve mutual contact and friction, scraping away non-medicinal parts such as residual stems, rough bark, and placenta from the surface of the medicinal materials. During the axial transport of the rhizome-type medicinal materials driven by the inner spiral blades, the transversely arranged scrapers also achieve mutual contact and friction, scraping away non-medicinal parts such as residual stems, rough bark, and placenta from the surface of the medicinal materials. Arranging the scrapers in both transverse and longitudinal configurations enhances the mutual contact and friction effect on the rhizome-type medicinal materials, thereby improving the removal efficiency of non-medicinal parts such as residual stems, rough bark, and placenta from the surface of the medicinal materials.

[0035] Scrape off the non-medicinal parts such as residual stems, rough bark, and placenta from the surface of root and rhizome medicinal materials with a scraper.

[0036] The cleaned rhizomes and other medicinal herbs are placed inside a drum. As the drum rotates, the herbs come into contact with and rub against scrapers on the inner wall. The scrapers remove non-medicinal parts such as residual stems, rough bark, and placenta from the surface of the herbs, which are then discharged through scraping holes outside the drum, achieving separation. A fixed cylinder collects these discharged non-medicinal parts. Throughout the process, hot air is introduced into the hot air channel and discharged into the drum through air outlets, removing moisture from the surface of the rhizomes and other medicinal herbs. This drying process, while removing non-medicinal parts, facilitates subsequent processing of the herbs.

[0037] Example 2: A pretreatment device for cleaning root and rhizome Chinese medicinal materials (see attached document) Figure 2 Its structure is similar to that of Embodiment 1, with the main difference being that a positioning cylinder 20 is installed above the feed hopper in this embodiment, and the lower end of the positioning cylinder is correspondingly connected to the upper end of the feed hopper. A centrifuge cylinder is rotatably installed inside the positioning cylinder, with a gap between the centrifuge cylinder and the positioning cylinder. The centrifuge cylinder includes an inner cylinder 21 and an outer cylinder 22. The inner cylinder can move up and down, and the inner cylinder and the outer cylinder are circumferentially locked. A drive gear ring 23 is provided on the outer wall of the outer cylinder. A centrifuge motor 24 is installed on the positioning cylinder, and a drive gear 25 is installed on the output shaft of the centrifuge motor. The drive gear meshes with the drive gear ring for transmission. A flip cover 26 is installed at the lower end of the inner cylinder, and the flip cover is hinged to the lower end of the inner cylinder. A positioning torsion spring is installed between the flip cover and the inner cylinder to close the flip cover at the lower end of the inner cylinder. A push rod 27 is provided below the flip cover inside the positioning cylinder. The inner cylinder moves downward to make the flip cover push against the push rod, thereby opening the flip cover. The flip cover extends outward near the hinge point with the inner cylinder to form a top contact part 28. The inner cylinder moves downward to make the top contact part push against the push rod, thereby opening the flip cover. The inner cylinder sidewall is densely covered with drainage inner holes 29, and the outer cylinder sidewall is densely covered with drainage outer holes 30, with the drainage inner holes and drainage outer holes being set one-to-one.

[0038] The upper end of the outer cylinder is provided with several sliding grooves 31, and the upper end of the inner cylinder is equipped with a rotatable limiting ring 32. A cover ring 33 is fastened above the upper limiting ring of the inner cylinder, and the cover ring limits the limiting ring. A support block 34 is provided at the lower end of the limiting ring and corresponding to the sliding groove. The rotation of the limiting ring causes the support block to slide into the sliding groove or be supported on the upper end of the outer cylinder. A positioning ring 35 is connected to the upper end of the positioning cylinder. The positioning ring and the outer cylinder are movably fitted together. The centrifugal motor is installed on the positioning ring, and a fixing ring 36 is provided above the drive gear ring. The fixing ring is connected to the positioning ring through a support rod and positions the outer cylinder. A stepped surface 37 is provided inside the positioning cylinder, and an extension ring 38 is provided at the lower end of the outer cylinder. The edge of the extension ring is supported on the stepped surface. An impurity outlet 39 is provided on the side wall of the positioning cylinder, and the impurity outlet is located close to the stepped surface. Other structures are the same as in Embodiment 1.

[0039] After cleaning, the root and rhizome medicinal materials are first placed in a centrifuge. The centrifuge's rotation centrifuges the materials, causing residual moisture to be expelled through the inner and outer drainage holes, achieving initial drying. Under centrifugal force, residual roots from the medicinal materials enter the drainage holes. After the centrifuge stops rotating, the inner cylinder moves downwards, causing the drainage holes to shift and cut off the remaining roots, achieving initial removal of residual roots. During the downward movement of the inner cylinder, the flap pushes against the top rod, opening the flap and allowing the root and rhizome medicinal materials to fall into the feed hopper. This initial centrifugation process, achieving preliminary drying and removal of residual roots, before the materials are placed into the drum, improves both the removal and drying efficiency of residual roots.
