Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine processing machinery technology, specifically a multi-stage dust-collecting pulverizer for pulverizing traditional Chinese medicine raw materials. Background Technology

[0002] In the processing of traditional Chinese medicine, pulverization is an indispensable step. While commercially available pulverizers can accomplish basic pulverization tasks, their dust collection capabilities still need improvement, especially the lack of an effective mechanism for classifying and collecting dust of different particle sizes. This leads to a certain degree of waste of usable dust.

[0003] Currently, conventional herbal medicine pulverizers mainly rely on a single dust collection device for dust collection. This method does not take into account the differences in dust particle size, and therefore cannot achieve graded collection. Because existing technology cannot implement graded collection, when processing multi-dusty materials, a large amount of fine dust containing usable medicinal herb components is mistakenly regarded as waste. This not only wastes resources but also reduces the overall utilization rate of medicinal herbs. This problem urgently needs to be solved to improve production efficiency and resource utilization. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a multi-stage dust-collecting pulverizer for pulverizing Chinese herbal medicine raw materials, which has advantages such as improved resource utilization and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a multi-stage dust-collecting pulverizer for pulverizing Chinese herbal medicine raw materials, including a fixed frame, wherein a pulverizing mechanism is provided on the right side of the fixed frame;

[0006] The crushing mechanism includes a crushing tank, a feed inlet, a crushing shaft, a set of coarse crushing blades, and multiple sets of fine crushing blades;

[0007] Two collection mechanisms are respectively provided on the upper left and lower left of the fixed frame;

[0008] Both of the aforementioned collection mechanisms include a collection tank, a filter screen, a cover plate, an anti-clogging shaft, and a cleaning blade;

[0009] A separation mechanism is provided between the two collection mechanisms;

[0010] The separation mechanism includes a cyclone separator body, a feed pipe, a bottom discharge pipe, and a top discharge pipe.

[0011] The above scheme, through graded collection, achieves graded collection of dust generated during the pulverization process at 400 mesh and 1000 mesh, effectively solving the problem of dust waste in high-dust materials and significantly improving the utilization rate of Chinese medicinal materials. By adding a separation mechanism and utilizing the cyclone separation principle, the accuracy of graded collection is further improved, ensuring the accuracy of dust grading and contributing to the efficient utilization of Chinese medicinal materials. The pulverizing blades inside the pulverizing tank, including coarse and fine blades, significantly improve pulverization efficiency and fineness, thereby enhancing the overall effect and quality of Chinese herbal medicine processing. The cleaning blades continuously clean the filter screen, effectively preventing filter clogging and ensuring collection efficiency.

[0012] Furthermore, the grinding tank is fixedly connected to the right end of the fixed frame, the two ends of the grinding shaft are rotatably connected to the inner top wall and inner bottom wall of the grinding tank respectively, each of the coarse grinding blades is fixedly connected to the top end of the grinding shaft, each group of fine grinding blades is fixedly connected to the bottom end of the grinding shaft, and the feed port is fixedly connected to the outer surface of the top end of the grinding tank.

[0013] With the above scheme and setup, the coarse crushing blade initially crushes the incoming raw material, breaking it down into smaller particles. The fine crushing blade is located downstream of the coarse crushing blade and further crushes the initially crushed raw material, ensuring that the fineness of the final product meets production requirements. This multi-layer blade design not only improves crushing efficiency but also ensures stable and reliable crushing quality.

[0014] Furthermore, the two collection tanks are fixedly connected to the top and bottom of the fixing frame, respectively. Each filter screen is fixedly connected to the right end of the inner wall of the collection tank adjacent to it. The left end of each anti-clogging shaft is rotatably connected to the filter screen adjacent to it. The right end of each anti-clogging shaft is rotatably connected to the right inner side wall of the collection tank adjacent to it. Each cleaning leaf is fixedly connected to the left end of the anti-clogging shaft adjacent to it. Each cleaning leaf contacts the left side of the filter screen adjacent to it. Each cover plate is hinged to the left end of the collection tank adjacent to it.

[0015] The above scheme and settings can intercept herbal particles in the gas, and the cleaning leaf can continuously scrape the filter surface to prevent clogging.

[0016] Furthermore, the feed pipe is fixedly connected to the top of the outer surface of the cyclone separator body, the top of the bottom discharge pipe is fixedly connected to the bottom of the cyclone separator body, the top of the top discharge pipe is fixedly connected to the upper collection tank, and the bottom of the top discharge pipe is fixedly connected to the upper surface of the cyclone separator body.

[0017] The above scheme, through the installation of a cyclone separator, can achieve the purpose of separating herbal particles from dust.

[0018] Furthermore, the uppermost filter screen has a mesh size of 1000, and the lowermost filter screen has a mesh size of 400.

[0019] The above scheme uses a 400-mesh filter specifically for collecting dust particles larger than or equal to 400 mesh. This dust, due to its moderate particle size, can be reused. The 1000-mesh filter is responsible for collecting fine dust particles smaller than 1000 mesh. This type of dust contains more particulate impurities from the air and is usually no longer used in subsequent production.

[0020] Furthermore, both collection tanks have an air outlet groove at their right ends.

[0021] The above solution, with the addition of an exhaust trough, facilitates the discharge of gas.

[0022] Furthermore, a discharge chute is provided at the bottom of the pulverizing tank.

[0023] The above method facilitates the falling of pulverized herbs.

[0024] Furthermore, a vacuum cleaner is fixedly installed on the upper right surface of the fixed frame. The input end of the vacuum cleaner is fixedly connected to the bottom end of the grinding tank, and the output end of the vacuum cleaner is fixedly connected to the feed pipe. The right ends of the two anti-clogging shafts and the bottom end of the grinding shaft are respectively fixedly connected to the external motor output end.

[0025] The above solution, through the installation of a vacuum cleaner, enables the dust generated during pulverization to be conveyed into the main body of the cyclone separator.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0027] This multi-stage dust-collecting pulverizer for crushing Chinese herbal raw materials achieves graded collection of dust generated during the pulverization process at 400 mesh and 1000 mesh, effectively solving the problem of dust waste in high-dust materials and significantly improving the utilization rate of Chinese medicinal materials. By adding a separation mechanism and utilizing the cyclone separation principle, the accuracy of graded collection is further improved, ensuring the accuracy of dust grading and contributing to the efficient utilization of Chinese medicinal materials. The pulverizing blades inside the pulverizing tank, including coarse and fine blades, significantly improve pulverization efficiency and fineness, thereby enhancing the overall effect and quality of Chinese herbal processing. The cleaning blades continuously clean the filter screen, effectively preventing filter clogging and ensuring collection efficiency. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The multi-stage dust-collecting pulverizer for pulverizing Chinese herbal raw materials in this embodiment includes a fixed frame 1, and a pulverizing mechanism 2 is provided on the right side of the fixed frame 1.

[0036] The pulverizing mechanism 2 includes a pulverizing tank 201, a feed inlet 202, a pulverizing shaft 203, a set of coarse pulverizing blades 204, and multiple sets of fine pulverizing blades 205. The pulverizing tank 201 is fixedly connected to the right end of the fixed frame 1. The two ends of the pulverizing shaft 203 are rotatably connected to the inner top wall and inner bottom wall of the pulverizing tank 201, respectively. Each coarse pulverizing blade 204 is fixedly connected to the top end of the pulverizing shaft 203, and each set of fine pulverizing blades 205 is fixedly connected to the bottom end of the pulverizing shaft 203. The feed inlet 202 is fixedly connected to the outer surface of the top end of the pulverizing tank 201. Through the above arrangement, the coarse pulverizing blades 204 perform preliminary crushing on the incoming raw materials, breaking them down into smaller particles. The fine pulverizing blades 205 are located downstream of the coarse pulverizing blades and further crush the raw materials that have undergone preliminary crushing, ensuring that the fineness of the final product meets the production requirements. Through this multi-layer blade design, not only is the pulverizing efficiency improved, but the stability and reliability of the pulverizing quality are also ensured. The bottom end of the pulverizing tank 201 is provided with a discharge chute 6, which facilitates the falling of the pulverized herbs.

[0037] Two collection mechanisms 3 are respectively provided on the upper left and lower left of the fixed frame 1.

[0038] Please see Figure 1 , Figure 3 and Figure 4 Both collection mechanisms 3 include a collection tank 301, a filter screen 302, a cover plate 303, an anti-clogging shaft 304, and a cleaning leaf 305. The two collection tanks 301 are fixedly connected to the top and bottom of the fixing frame 1, respectively. Each filter screen 302 is fixedly connected to the right end of the inner wall of the adjacent collection tank 301. The left end of each anti-clogging shaft 304 is rotatably connected to the adjacent filter screen 302, and the right end of each anti-clogging shaft 304 is rotatably connected to the right inner wall of the adjacent collection tank 301. Each cleaning leaf 305 is fixedly connected to the left end of its adjacent anti-clogging shaft 304. Each cleaning leaf 305 is in contact with the left side of its adjacent filter screen 302. Each cover plate 303 is hinged to the left end of its adjacent collection tank 301. Through the above arrangement, herbal particles in the gas can be intercepted. The cleaning leaf 305 can continuously scrape the surface of the filter screen 302 to avoid clogging. Both collection tanks 301 have an exhaust groove 5 on their right ends. The exhaust groove 5 facilitates the discharge of gas.

[0039] A separation mechanism 4 is provided between the two collection mechanisms 3.

[0040] Please see Figure 1 , Figure 2 and Figure 4The separation mechanism 4 includes a cyclone separator body 401, a feed pipe 402, a bottom discharge pipe 403, and a top discharge pipe 404. The feed pipe 402 is fixedly connected to the top of the outer surface of the cyclone separator body 401. The top of the bottom discharge pipe 403 is fixedly connected to the bottom of the cyclone separator body 401. The top of the top discharge pipe 404 is fixedly connected to the upper collection tank 301. The bottom of the top discharge pipe 404 is fixedly connected to the upper surface of the cyclone separator body 401. By setting up the cyclone separator, the purpose of separating herbal particles in dust can be achieved.

[0041] Please see Figure 1 , Figure 3 and Figure 4 The topmost filter 302 is 1000 mesh, and the bottommost filter 302 is 400 mesh. The 400 mesh filter 302 is specifically used to collect dust particles larger than or equal to 400 mesh. This part of the dust can be reused because of its moderate particle size. The 1000 mesh filter 302 is responsible for collecting fine dust particles smaller than 1000 mesh. This type of dust contains more particulate impurities from the air and is usually no longer used in subsequent production. A vacuum cleaner 7 is fixedly installed on the upper right surface of the fixed frame 1. The input end of the vacuum cleaner 7 is fixedly connected to the bottom end of the crushing tank 201, and the output end of the vacuum cleaner 7 is fixedly connected to the feed pipe 402. The right ends of the two anti-clogging shafts 304 and the bottom end of the crushing shaft 203 are fixedly connected to the external motor output end, respectively. Through the setting of the vacuum cleaner 7, the dust generated by crushing can be transported into the cyclone separator body 401.

[0042] This embodiment of a multi-stage dust-collecting pulverizer for pulverizing Chinese herbal raw materials achieves graded collection of dust generated during the pulverization process at 400 mesh and 1000 mesh levels, effectively solving the problem of dust waste in high-dust materials and significantly improving the utilization rate of Chinese herbal materials. By adding a separation mechanism 4 and utilizing the cyclone separation principle, the accuracy of graded collection is further improved, ensuring the accuracy of dust grading and contributing to the efficient utilization of Chinese herbal materials. The pulverizing blades inside the pulverizing tank 201, including coarse and fine blades, significantly improve pulverization efficiency and fineness, thereby enhancing the overall effect and quality of Chinese herbal processing. The cleaning blades 305 continuously clean the filter screen 302, effectively preventing clogging of the filter screen 302 and ensuring collection efficiency.

[0043] The working principle of the above embodiment is as follows: First, the herbal raw materials are fed into the pulverizing tank 201 through the feed inlet 202. As the pulverizing shaft 203 rotates, the coarse pulverizing blade 204 at its top first performs preliminary crushing of the raw materials, breaking them down into smaller particles. Subsequently, these preliminarily crushed raw materials enter the area of ​​the fine pulverizing blade 205, where the fine pulverizing blade 205 further finely crushes the raw materials, ensuring that the fineness of the final product meets production requirements. This multi-stage blade design not only improves pulverizing efficiency but also ensures the stability and reliability of pulverizing quality. During the pulverizing process, the dust generated is sucked in by the vacuum cleaner 7 at the bottom of the pulverizing tank 201 and transported to the feed pipe 402 of the cyclone separator body 401 through the output end of the vacuum cleaner 7. After entering the cyclone separator, due to the action of the rotating airflow, the herbal particles in the dust are separated, among which the larger dust particles of 400 mesh and above are separated. The dust is discharged through the bottom discharge pipe 403 and collected in the collection tank 301 below. This part of the dust has high reuse value due to its moderate particle size. The fine dust with a particle size of less than 1000 mesh rises with the airflow to the top discharge pipe 404 and is collected in the collection tank 301 above. This type of dust contains more particulate impurities in the air and is usually no longer used for subsequent production. At the same time, in order to keep the filter screen 302 in the collection tank 301 unobstructed and prevent clogging, each collection tank 301 is equipped with an anti-clogging shaft 304 and a cleaning blade 305. As the anti-clogging shaft 304 rotates, the cleaning blade 305 continuously scrapes the surface of the filter screen 302 to remove the attached dust particles, ensuring that the dust can pass smoothly through the filter screen 302 into the collection tank 301. When it is necessary to clean the collection tank 301 or check the filter screen 302, the collection tank 301 can be easily opened through the hinged cover plate 303.
