Description

Technical Field

[0001] This invention relates to the field of screening machine technology, and more specifically, to a vibrating screening machine for traditional Chinese medicine. Background Technology

[0002] In the production and processing of Chinese medicinal materials, screening is usually required to classify the materials according to their size or remove impurities, thereby improving the purity of the materials and obtaining raw materials with good uniformity. This allows for accurate control of the dosage of the materials and ensures the quality of the product in subsequent preparation processes.

[0003] Among them, patent CN219003707U discloses a traditional Chinese medicine sieving device including a box body and several sieve plates. The sieve plates are embedded in the box body from top to bottom. One end of the box body has a feed inlet, and the other end has several discharge outlets. The bottom of the box body is provided with a vibration drive for driving the box body to vibrate. Several limiting strip groups are provided on each inner side of the box body. Several limiting strip groups on the two inner side walls of the box body are arranged one-to-one, and a channel for material to pass through is formed between two adjacent limiting strip groups.

[0004] In operation, this structure adjusts the height of the corresponding channel by changing the distance between two adjacent limit strip groups. This allows the material to move along the corresponding channel to the corresponding discharge port when screening larger particles, making one screening device suitable for screening materials of various sizes. However, after entering the housing from the inlet, the material tends to aggregate on the screen plate surface. Vibration alone is insufficient to achieve uniform dispersion, resulting in a large amount of material concentrating in a localized area of ​​the screen plate and exiting the channel without sufficient contact with the screen holes, leading to low screening efficiency. This machine is suitable for processing various medicinal materials, such as sliced ​​ginseng and angelica, granules (like goji berries and hawthorn), and powders (like Panax notoginseng powder and Fritillaria cirrhosa powder). Furthermore, dust adhering to the surface of these medicinal materials is easily dispersed into the air during vibration, causing environmental pollution. Additionally, some dust may enter subsequent processes with the screened material, affecting the purity of the medicinal materials. The combined structure of the sieve plate and channel can only achieve single-dimensional sieving, making it impossible to perform multi-level fine classification of materials. This makes it difficult to meet the need for separate utilization of materials of different particle sizes in the processing of medicinal materials, thus limiting its applicability. Therefore, this vibrating sieve machine for traditional Chinese medicine is provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vibrating sieve for traditional Chinese medicine, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a vibrating sieve for traditional Chinese medicine, including a base, on which a sieve assembly is provided;

[0007] The screening assembly includes a screening cylinder located in the middle of the base. A pad is provided at the top of the inner cavity of the screening cylinder. A diverting cone is provided at the top of the pad. A plurality of first gears are rotatably connected to the bottom of the pad. A gathering hopper is provided in the middle of the plurality of first gears. Each first gear is circumferentially distributed along the axial direction of the diverting cone. A plurality of through holes are provided on the pad, each of which is connected to the gathering hopper.

[0008] The inner wall of the gathering hopper is provided with a feed screen block for diverting the flow. The bottom of the first gear is provided with a limit cover, which covers the outside of the gathering hopper. The bottom of the limit cover is provided with a protective sleeve, which is installed in the screen cylinder by bolts. A first screen cylinder is provided in the middle of the protective sleeve, and a second screen cylinder is provided in the middle of the first screen cylinder. Several material distribution rods are provided between the first screen cylinder and the second screen cylinder. The material distribution rods are fixed in the protective sleeve by flanges. Several through holes are respectively opened on the first screen cylinder and the second screen cylinder.

[0009] Optionally, in one possible implementation, a central filter element is installed in the middle of the second screen cylinder via a crossbar. A flow guide groove is opened in the middle of the central filter element. A filter screen cylinder is arranged in the middle of the flow guide groove. A supporting cone is arranged at the top of the filter screen cylinder. Several flow dividers are arranged on the outer side of the supporting cone, and the outer side of each flow divider extends to the inner wall of the collecting hopper. An installation plate is arranged at the bottom of the supporting cone. Several material distribution arc plates are distributed on the outer side of the installation plate. Several material guide plates are distributed at the top of the installation plate. An impeller is rotatably connected to the bottom of the protective sleeve. The impeller is sleeved on the bottom end of the filter screen cylinder and is connected to the flow guide groove.

[0010] Optionally, in one possible implementation, a second gear is rotatably connected to the bottom of the pad, the first gear meshes with the second gear, and the pad is bolted inside the screening cylinder. A motor for driving the second gear to rotate is provided at the bottom of the screening cylinder, a cover plate is provided at the top of the screening cylinder, and limit handles for limiting the screening cylinder are provided on both sides of the base. The supporting cone is shaped like a frustum, and the vertical cross-section of the gathering bucket is cone-shaped. The first gear is rotatably connected to the limit cover, and the gathering bucket is bolted to the middle of the first gear.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention uses a diversion cone to quickly disperse falling materials in all directions, avoiding material concentration in the initial stage; the feed screen block on the inner wall of the gathering hopper not only achieves preliminary filtration, but also guides the material to flow evenly; the diversion plate on the outside of the supporting cone and the guide plate and distribution arc plate on the mounting plate further guide and disperse the material, ensuring that the material is in a uniform distribution state before entering the screening area, thus completely solving the problem of material agglomeration in existing equipment.

[0013] 2. In this invention, the motor drives the second gear to work in conjunction with the first gear, causing the gathering bucket, the first screen cylinder, the second screen cylinder, and the filter cylinder to rotate synchronously. Under the action of centrifugal force, the material comes into full contact with the screen cylinder. Combined with the multi-stage screening structure of the first and second screen cylinders, a step-by-step screening process of preliminary filtration, coarse screening, and fine screening is realized. It can also complete the classification of materials of different particle sizes in one go. Furthermore, the material distribution bar between the first and second screen cylinders can divert the material between the two screen cylinders in real time, preventing the material from adhering to the inner wall of the screen cylinder due to centrifugal force and forming accumulation, ensuring that the screen holes are always unobstructed, and further ensuring the stability of screening efficiency.

[0014] 3. The airflow generated by the impeller of the present invention is transported to the second screen cylinder through the guide groove. The airflow blows the material into suspension, causing the dust on the surface of the material to fall off. At the same time, the centrifugal force generated by the rotation of the filter cylinder draws the dust into the filter cylinder and discharges it from the equipment, so as to realize the simultaneous screening and dust removal, significantly improve the purity of Chinese medicinal materials, and reduce the workload of subsequent cleaning processes.

[0015] In summary, by using the diversion plate on the outside of the supporting cone and the guide plate and distribution arc plate on the mounting plate to further guide and disperse the material, it is ensured that the material is in a uniform distribution state before entering the screening area. This completely solves the problem of material agglomeration in existing equipment, realizes a step-by-step screening process of preliminary filtration, coarse screening and fine screening, and can complete the classification of materials of different particle sizes in one go. Furthermore, the distribution rod between the first screen cylinder and the second screen cylinder can divert the material between the two screen cylinders in real time, preventing the material from adhering to the inner wall of the screen cylinder due to centrifugal force and forming accumulation, ensuring that the screen holes are always unobstructed, and further guaranteeing the stability of screening efficiency.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This embodiment discloses a vibrating sieve for traditional Chinese medicine, which aims to solve the problem that materials in existing traditional Chinese medicine sieving equipment tend to agglomerate and are difficult to effectively separate, resulting in low sieving efficiency.

[0029] Specifically, as shown in the attached document Figure 1As shown, the Chinese medicine vibrating sieve includes a base 1, which serves as the supporting foundation for the entire equipment. On both sides of the base 1, there are limit handles 26 for limiting the screen cylinder 2. The limit handles 26 can be adjusted to ensure that the screen cylinder 2 remains stable during operation and to avoid displacement due to vibration or rotation.

[0030] The base 1 is equipped with a sieving component, which is the core structure for sieving Chinese medicine. It includes a sieve cylinder 2 located in the middle of the base 1. The top of the sieve cylinder 2 is equipped with a cover plate 24. The cover plate 24 is connected to the sieve cylinder 2 by a snap fastener. Opening the cover plate 24 allows for easy addition of Chinese medicine to be sieved into the sieve cylinder 2. When closed, it prevents material from splashing and external impurities from entering during the sieving process.

[0031] The bottom of the screening cylinder 2 is equipped with a motor 25 for driving the second gear 23 to rotate. The motor 25 is fixed to the base 1 by bolts. The output shaft of the motor 25 is connected to the second gear 23 by a coupling to provide power for the rotation of the entire screening assembly.

[0032] As attached Figure 2 As shown, a pad 3 is provided at the top of the inner cavity of the screening cylinder 2. The pad 3 is installed inside the screening cylinder 2 by bolts. The installation method is simple and reliable, and it is convenient for later disassembly and maintenance. The bottom of the pad 3 is rotatably connected to a second gear 23 and several first gears 5. The first gears 5 mesh with the second gear 23. When the motor 25 drives the second gear 23 to rotate, the second gear 23 drives the multiple first gears 5 meshing with it to rotate synchronously. Each first gear 5 is circumferentially distributed along the axis of the diversion cone 4. This distribution method can ensure that the subsequent material diversion is uniform.

[0033] As attached Figure 3 Appendix Figure 6 As shown, multiple first gears 5 are bolted to the middle sections of each collecting hopper 6. The vertical cross-section of the collecting hopper 6 is conical, which facilitates the rapid convergence and downward flow of materials, preventing material accumulation within the collecting hopper 6. Several through holes, all connected to the collecting hopper 6, are formed on the pad 3. After entering the screening cylinder 2, the material first contacts the diversion cone 4 at the top of the pad 3. The diversion cone 4 is conical and disperses the falling material in all directions, ensuring even flow into each collecting hopper 6, achieving initial diversion. The inner wall of the collecting hopper 6 is equipped with a feed screen 7 for diversion. The feed screen 7 has several small sieve holes, which perform preliminary filtration of the material as it enters the collecting hopper 6, filtering out some fine impurities or tiny particles that do not meet size requirements, and further assisting in material diversion.

[0034] A limiting cover 8 is provided at the bottom of the first gear 5. The first gear 5 is rotatably connected to the limiting cover 8. The limiting cover 8 covers the outside of the gathering hopper 6, which can protect the gathering hopper 6 and prevent it from colliding with other parts during rotation. It also prevents materials from leaking out of the gap between the gathering hopper 6 and other structures. A protective sleeve 21 is provided at the bottom of the limiting cover 8. The protective sleeve 21 is installed in the screening cylinder 2 by bolts. A first screening cylinder 9 is provided in the middle of the protective sleeve 21. A second screening cylinder 10 is provided in the middle of the first screening cylinder 9. Several through holes 12 are opened through the first screening cylinder 9 and the second screening cylinder 10 respectively. The diameter of the through holes 12 on the first screening cylinder 9 is smaller than the diameter of the through holes 12 on the second screening cylinder 10, which can realize the grading and screening of materials of different sizes. Several material distribution rods 11 are provided between the first screen cylinder 9 and the second screen cylinder 10. The material distribution rods 11 are fixed in the protective sleeve 21 by flanges. The material distribution rods 11 are evenly distributed in a circle. When the first screen cylinder 9 and the second screen cylinder 10 rotate, the material distribution rods 11 can divert the material between the two screen cylinders, so that the material is dispersed and avoids accumulation that affects the screening effect.

[0035] As attached Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 As shown, a central filter element 13 is installed in the middle of the second sieve cylinder 10 via a crossbar. The crossbar is welded to both the second sieve cylinder 10 and the central filter element 13 to ensure a secure connection. A guide groove 14 is formed in the middle of the central filter element 13, and a filter screen cylinder 15 is positioned in the middle of the guide groove 14. The outer side of the filter screen cylinder 15 has a filter screen structure, allowing air and dust to pass through while blocking medicinal herb particles. A supporting cone 16 is provided at the top of the filter screen cylinder 15. The supporting cone 16 is shaped like a frustum. This frustum structure not only provides stable support for the filter screen cylinder 15 but also guides the material falling from the gathering hopper 6 to evenly enter the area between the second sieve cylinder 10 and the central filter element 13. Several diversion plates 17 are provided on the outer side of the supporting cone block 16, and the outer side of each diversion plate 17 extends to the inner wall of the gathering hopper 6. The diversion plates 17 are welded or bolted to the supporting cone block 16 and the gathering hopper 6. When the gathering hopper 6 rotates, the diversion plates 17 can further divert the material in the gathering hopper 6 to ensure that the material enters the subsequent screening area evenly.

[0036] As attached Figure 9As shown, a mounting plate 18 is provided at the bottom of the supporting cone 16. The mounting plate 18 is connected to the supporting cone 16 by bolts. Several material distribution arc plates 19 are distributed on the outer side of the mounting plate 18. The material distribution arc plates 19 are arc-shaped and can guide and disperse the material during its fall, preventing the material from accumulating. Several guide plates 20 are distributed at the top of the mounting plate 18. The guide plates 20 are inclined and can guide the material falling from the supporting cone 16 smoothly into the space between the second screen cylinder 10 and the central filter element 13, further improving the material diversion effect. An impeller 22 is rotatably connected to the bottom of the protective sleeve 21. The impeller 22 is sleeved on the bottom end of the filter cylinder 15 and is connected to the guide groove 14. The impeller 22 and the filter cylinder 15 are connected by a key. When the filter cylinder 15 rotates, it can drive the impeller 22 to rotate synchronously.

[0037] The specific working principle is as follows: First, open the cover plate 24 at the top of the sieve cylinder 2, pour the Chinese medicinal materials to be sieved into the sieve cylinder 2, and close the cover plate 24. Start the motor 25, which drives the second gear 23 to rotate. Since the first gear 5 meshes with the second gear 23, the second gear 23 drives multiple first gears 5 to rotate synchronously, which in turn drives the gathering hopper 6, the diverting plate 17, the supporting cone 16, the filter cylinder 15 and other components connected to the first gear 5 to rotate in linkage. The falling Chinese medicinal materials first come into contact with the diverting cone 4 at the top of the pad 3, and are dispersed in all directions under the action of the diverting cone 4, flowing evenly into each gathering hopper 6 through the through holes on the pad 3, realizing the initial diversion of materials.

[0038] The material entering the gathering hopper 6 is initially filtered through the screen holes of the inner wall feeding screen block 7 by the rotation of the gathering hopper 6 and the action of the inner wall feeding screen block 7. At the same time, the material flows smoothly downward under the guidance of the conical gathering hopper 6 and the diversion plate 17 and enters the area between the second screen cylinder 10 and the central filter element 13.

[0039] After the material enters between the second screen cylinder 10 and the central filter element 13, due to the rotation of the second screen cylinder 10 with the overall structure, under the action of centrifugal force, smaller particles that meet the size requirements of the through hole 12 of the second screen cylinder 10 enter the area between the first screen cylinder 9 and the second screen cylinder 10 through the through hole 12; larger particles that do not meet the size requirements continue to flow inside the second screen cylinder 10.

[0040] Material entering between the first screen cylinder 9 and the second screen cylinder 10 is discharged through the through-hole 12 of the first screen cylinder 9 into the area between the protective sleeve 21 and the first screen cylinder 9 under the centrifugal force generated by the rotation of the first screen cylinder 9. Particles meeting the size requirements of the first screen cylinder 9's through-hole 12 are discharged. Simultaneously, the material distribution rod 11 diverts the material between the two screen cylinders to prevent material accumulation and ensure continuous and efficient screening.

[0041] During the rotation of the filter cylinder 15, it drives the impeller 22 at the bottom to rotate synchronously. The rotation of the impeller 22 generates airflow, which is conveyed to the second screen cylinder 10 through the guide groove 14. The airflow blows the material in the second screen cylinder 10 into suspension, which not only facilitates particle separation but also separates dust from the material surface. At the same time, the rotation of the filter cylinder 15 generates centrifugal force, which draws the separated dust into the filter cylinder 15. Subsequently, the dust is discharged from the bottom of the filter cylinder 15 with the airflow, ensuring the quality of the screened material and preventing dust from contaminating the screened material.

[0042] As attached Figure 5 As shown, after screening, materials of different sizes are collected between the protective sleeve 21 and the first sieve cylinder 9, and inside the second sieve cylinder 10, and discharged through the outlet set at the corresponding position at the bottom of the protective sleeve 21, thus realizing the graded collection of Chinese medicinal materials.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
