Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing equipment technology, and more specifically, to a mixing tank for processing traditional Chinese medicine. Background Technology

[0002] In the processing and production of traditional Chinese medicine, it is often necessary to mix and stir various Chinese medicinal materials or Chinese medicinal materials with excipients to ensure the smooth progress of subsequent extraction, preparation and other processes, while ensuring the quality and efficacy of Chinese medicine products.

[0003] The processing of traditional Chinese medicine involves diverse material forms, including granules, powders, lumps, and viscous materials containing a certain amount of moisture. The fixed trajectory of a single stirring paddle easily creates dead zones within the tank, leading to uneven mixing. Especially for highly viscous materials, localized agglomeration is prone to occur, affecting not only the subsequent extraction efficiency of active ingredients but also potentially causing material deterioration due to localized overheating, thus reducing product quality. Therefore, we propose a mixing tank for processing traditional Chinese medicine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a mixing tank for processing traditional Chinese medicine, so as to solve the technical problem that there are dead zones in the current mixing tank, resulting in uneven mixing of materials.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A mixing tank for processing traditional Chinese medicine includes a mixing tank body, and a stirring mechanism for stirring is fixedly installed downward on the top cover plate of the mixing tank body; The stirring mechanism includes a dual-shaft assembly fixed to the top of the main body cover plate of the stirring tank. One output end of the dual-shaft assembly is fixedly connected to a stirring component located inside the main body of the stirring tank, and the other output end of the dual-shaft assembly is fixedly installed with a scraping component that fits against the inner wall of the main body of the stirring tank. The dual-shaft assembly includes a drive motor, and a support frame fixedly connected to the drive motor is fixedly installed on the top of the mixing tank body. A drive gear is fixedly installed on the output shaft of the drive motor, and a C-shaped fixing frame is sleeved on the outer wall of the output shaft of the drive motor. Bearing seats are fixedly installed at both ends of the fixing frame. A connecting block fixedly connected to the support frame is fixedly installed on the side of the top bearing seat. Driven gears that mesh with the drive gear are rotatably installed on the opposing surfaces of the two bearing seats. The lower driven gear is fixedly connected to the end of the mixing assembly, and the upper driven gear is fixedly connected to the end of the scraping assembly.

[0006] This invention effectively solves the problem of dead zones in traditional single-paddle mixing by using a dual-shaft drive assembly to coordinate the operation of the stirring and scraping components. The stirring assembly actively stirs the medicinal materials within the tank, creating multi-angle, dead-zone-free mixing motion for materials of different forms, such as granules, powders, and viscous substances, preventing material agglomeration. Simultaneously, the scraping component, moving along the inner wall of the tank, scrapes off material adhering to the inner wall and re-rolls it into the stirring area, further promoting material circulation and mixing. This synergistic effect significantly improves the uniformity of material mixing, ensuring consistent distribution of the effective components of the medicinal materials. It avoids differences in extraction efficiency caused by uneven local mixing and prevents localized overheating and deterioration of viscous materials, providing strong assurance for the quality stability of traditional Chinese medicine products.

[0007] Preferably, the stirring assembly includes a stirring tube fixedly connected to the bottom driven gear, and a plurality of connecting rods are fixedly and alternately arranged on the tube wall of the stirring tube, with spiral stirring blades fixedly connected between the plurality of connecting rods.

[0008] Preferably, a spiral guide plate is also fixedly provided on the wall of the stirring tube, and the spiral guide plate is opposite to the spiral direction of the spiral stirring blade.

[0009] Preferably, the scraping assembly includes a fixing rod fixedly connected to the top driven gear, and the fixing rod passes through the bottom driven gear and fits against the inner wall of the stirring tube. The bottom end of the fixing rod is fixedly provided with a plurality of first scrapers that fit against the bottom side of the inner cavity of the stirring tank body.

[0010] Preferably, each of the ends of a plurality of first scrapers is vertically provided with a second scraper that fits against the inner wall of the mixing tank body, and each end of the opposite second scraper is horizontally fixedly provided with a connecting plate, and a sleeve fitted onto the outside of the mixing tube is fixedly connected between the ends of adjacent connecting plates.

[0011] Preferably, both the first scraper and the second scraper are made of stainless steel, and the sides of the first scraper and the second scraper that are in contact with the inner wall of the mixing tank are made of food-grade rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This invention effectively solves the problem of dead zones in traditional single-paddle mixing by using a dual-shaft drive assembly to coordinate the operation of the stirring and scraping components. The stirring assembly actively stirs the medicinal materials within the tank, creating multi-angle, dead-zone-free mixing motion for materials of different forms, such as granules, powders, and viscous substances, thus preventing material agglomeration. Simultaneously, the scraping component, moving along the inner wall of the tank, scrapes off material adhering to the inner wall and re-rolls it into the stirring area, further promoting material circulation and mixing. This synergistic effect significantly improves the uniformity of material mixing, ensuring consistent distribution of the effective components of the medicinal materials. This avoids differences in extraction efficiency caused by uneven local mixing and prevents localized overheating and deterioration of viscous materials, providing strong assurance for the quality stability of traditional Chinese medicine products.

[0013] 2. This utility model also strengthens the structural stability of the spiral stirring blades by using staggered fixed rods on the stirring tube, which can also disperse the medicinal materials in the tank laterally. Combined with the scraping component driving the scraper's circumferential motion, it realizes a three-dimensional stirring mode of "longitudinal convection + lateral dispersion + circumferential scraping", which completely solves the problem of insufficient stirring of medicinal materials at the bottom and near the inner wall of traditional stirring tanks, ensuring that the processing conditions of each batch of medicinal materials are consistent and guaranteeing the quality stability of the finished Chinese medicine products.

[0016] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0017] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0018] like Figures 1 to 4 As shown, this utility model relates to a mixing tank for processing traditional Chinese medicine, including a mixing tank body 1. A stirring mechanism 2 for stirring is fixedly installed downward on the top cover plate of the mixing tank body 1. The stirring mechanism 2 includes a dual-shaft assembly 3 fixed to the top of the cover plate of the mixing tank body 1. A stirring component 4 located inside the mixing tank body 1 is fixedly connected to one output end of the dual-shaft assembly 3, and a scraping component 5 that fits against the inner wall of the mixing tank body 1 is fixedly installed on the other output end of the dual-shaft assembly 3. By controlling the stirring component 4 and the scraping component 5 to rotate synchronously through the dual-shaft assembly 3, multi-directional stirring and scraping operations are realized, which improves the stirring effect while reducing the phenomenon of sticking to the wall and improving the thoroughness of mixing.

[0019] The dual-shaft assembly 3 includes a drive motor 301, and a support frame 101 fixedly connected to the drive motor 301 is fixedly installed on the top of the mixing tank body 1. A drive gear 302 is fixedly installed on the output shaft of the drive motor 301, and a C-shaped fixing frame 303 is sleeved on the outer wall of the output shaft of the drive motor 301. Bearing seats 304 are fixedly installed at both ends of the fixing frame 303. A connecting block 305 fixedly connected to the support frame 101 is fixedly installed on the side of the top bearing seat 304. The opposing surfaces of the two bearing seats 304 are rotatably mounted. The device is equipped with a driven gear 306 that meshes with the drive gear 302. The lower driven gear 306 is fixedly connected to the end of the stirring assembly 4, and the upper driven gear 306 is fixedly connected to the end of the scraping assembly 5. By driving the driven gear 302 to rotate the driven gears 306 on both sides in opposite directions, the stirring assembly 4 and the scraping assembly 5 can rotate in opposite directions, which improves the flexibility of the structure. Both the drive gear 302 and the driven gear 306 are bevel gears, and the driven gears on both sides face each other and rotate in opposite directions under the action of the drive gear 302.

[0020] In an embodiment of this utility model, the stirring assembly 4 includes a stirring tube 401 fixedly connected to the bottom driven gear 306. A plurality of connecting rods 402 are fixedly and alternately arranged on the tube wall of the stirring tube 401, and a spiral stirring blade 403 is fixedly connected between the plurality of connecting rods 402. The connecting rods 402 can support the spiral stirring blade 403 at different positions. The spiral stirring blade 403 generates an upward pushing force on the Chinese medicine raw materials in the tank in its own spiral direction, such as clockwise, so that the raw materials at the bottom are turned upward and the layering state of the raw materials is broken.

[0021] In an embodiment of this utility model, a spiral guide plate 404 is also fixedly provided on the wall of the stirring tube 401, and the spiral guide plate 404 and the spiral stirring blade 403 have opposite spiral directions; the downward flow of the spiral guide plate 404 forms a longitudinal convection circulation of the raw materials in the tank, which, together with the spiral stirring blade 403, achieves a convection mixing effect.

[0022] In an embodiment of this utility model, the scraping assembly 5 includes a fixing rod 501 fixedly connected to the top driven gear 306, and the fixing rod 501 passes through the bottom driven gear 306 and fits against the inner wall of the stirring tube 401. Several first scrapers 502 are fixedly provided at the bottom end of the fixing rod 501 and fit against the bottom side of the inner cavity of the mixing tank body 1. The fixing rod 501 can pass through the stirring tube 401 without affecting the rotation effect. The design of the first scrapers 502 can turn over the dregs settled at the bottom when rotating, preventing them from sticking to the bottom and affecting the mixing quality of the Chinese medicine.

[0023] In an embodiment of this utility model, the ends of several first scrapers 502 are each vertically provided with second scrapers 503 that fit against the inner wall of the mixing tank body 1. The ends of opposite second scrapers 503 are each horizontally fixed with connecting plates 504. The ends of adjacent connecting plates 504 are fixedly connected with sleeves 505 that are sleeved on the outside of the mixing tube 401. The design of the second scrapers 503 can scrape the material around the inner wall of the mixing tank body 1, further improving the fullness of the mixing of traditional Chinese medicine. The cooperation between the connecting plates 504 and the sleeves 505 can improve the support strength and prevent deformation caused by the pressure of the liquid flow.

[0024] In the embodiments of this utility model, both the first scraper 502 and the second scraper 503 are made of stainless steel, and the sides of the first scraper 502 and the second scraper 503 that are in contact with the inner wall of the mixing tank body 1 are made of food-grade rubber; this reduces wear and reduces the impact on the mixing quality of the medicine solution.

[0025] Working Principle: This embodiment provides a mixing tank for processing traditional Chinese medicine. When the equipment is started, the drive motor 301, fixed on the top support frame 101 of the mixing tank body 1, starts to run, and its output shaft drives the coaxially fixed drive gear 302 to rotate. A C-shaped fixing frame 303 is sleeved on the outside of the drive gear 302. The bearing seats 304 at both ends of the fixing frame 303 are fixed to the top support frame 101 of the tank through connecting blocks 305 to ensure stability. Two driven gears 306 (symmetrically distributed vertically) mesh with the drive gear 302 are rotatably installed. The rotational force of the drive gear 302 is synchronously transmitted to the upper and lower driven gears 306 through meshing. Due to the meshing relationship, the two driven gears 306 rotate in opposite directions. The upper driven gear 306 is fixed to the end of the scraping assembly 5, and the lower driven gear 306 is fixed to the end of the stirring assembly 4, thereby realizing the synchronous diversion of the single power of the drive motor 301 to the "stirring action" and the "scraping and cleaning action", providing the power foundation for the two core functions. The driven gear 306 on the lower side drives the stirring tube 401 of the stirring assembly 4 to rotate. Several connecting rods 402, which are interlaced and fixed on the wall of the stirring tube 401, rotate synchronously with the stirring tube 401, thereby driving the spiral stirring blades 403 fixed between the connecting rods 402 to rotate. The spiral stirring blades 403, in their own spiral direction (clockwise), generate an upward pushing force on the raw materials in the tank, causing the bottom materials to turn upwards and breaking up the stratification of the materials. A spiral guide plate 404 (counter-clockwise spiral) is also fixed on the wall of the stirring tube 401, with a spiral direction opposite to that of the spiral stirring blades 403. When the stirring tube 401 rotates, the spiral guide plate 404 generates a downward guiding force on the upper materials in the tank, causing the upper materials to flow downwards. The upward pushing motion of the spiral stirring blades 403 and the downward guiding motion of the spiral guide plate 404 create a longitudinal convection circulation of the raw materials inside the tank. Simultaneously, the rotation of the stirring tube 401 drives the entire stirring assembly 4 to rotate around the central axis of the tank, achieving circumferential mixing of the raw materials. This ultimately achieves a combined mixing effect of "longitudinal convection + circumferential stirring," ensuring uniform mixing of the herbal raw materials without dead zones. The upper driven gear 306 drives the fixed rod 501 of the scraping assembly 5 to rotate. The fixed rod 501 passes through the lower driven gear 306 and fits against the inner wall of the stirring tube 401, ensuring no deviation during rotation. Several first scrapers 502 at the bottom of the fixed rod 501 are tightly fitted against the bottom side of the inner cavity of the mixing tank body 1. As the fixed rod 501 rotates, the first scrapers 502 scrape the raw materials adhering to the bottom of the tank, preventing the raw materials from settling and deteriorating. The second scraper 503, vertically positioned at the end of the first scraper 502, fits tightly against the inner wall of the mixing tank body 1. As it rotates with the fixing rod 501, the second scraper 503 simultaneously scrapes away the raw material on the tank wall. At the same time, the transverse connecting plate 504 at the end of the second scraper 503 and the sleeve 505 fitted on the outside of the mixing tube 401 further ensure the stability of the second scraper 503, preventing the scraper from detaching from the tank wall due to centrifugal force during rotation, and ensuring that no part of the cleaning is missed.The base of the first scraper 502 and the second scraper 503 is made of stainless steel (to ensure strength and corrosion resistance), and the sides that fit against the tank wall / bottom are made of food-grade rubber. This avoids scratching the inner wall of the tank by the scraper and ensures that the Chinese medicine raw materials are not contaminated by metal, thus meeting the hygiene requirements for Chinese medicine processing.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
