Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine pulverization, and in particular to a device for ultra-fine pulverization and grading of Astragalus membranaceus. Background Technology
[0002] Astragalus is a perennial herb and a common traditional Chinese medicine for tonifying qi. In traditional Chinese medicine, astragalus is sweet and warm in nature, and enters the lung and spleen meridians. It has the effects of tonifying qi and strengthening the exterior, astringing sores and promoting tissue regeneration, and promoting diuresis and reducing swelling. Because the active ingredients of astragalus are mainly found inside cells, it is usually crushed into fine powder and made into pills, tablets, and injections for human use.
[0003] In existing technologies, Astragalus membranaceus is typically pulverized using a pulverizing rotor, and the powder is screened using a screen fixed at the rotor's discharge point. However, as a plant root, Astragalus membranaceus requires mechanical support, transport assistance, environmental adaptation, and defense mechanisms, resulting in a high fiber content. During pulverizing, this fiber easily forms long, fibrous particles. Furthermore, Astragalus membranaceus contains viscous substances such as polysaccharides and mucilage, which readily adhere to the particles when heated during pulverization. These particles, combined with the fibrous particles, easily form clumps that remain on the screen. This clogging of the screen prevents the removal of these clumps, hindering its screening function.
[0004] Therefore, this application provides an Astragalus cell wall breaking ultrafine pulverization and grading device to meet the requirements. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an Astragalus cell wall breaking and ultra-fine pulverizing and grading device to solve the problem that the fibrous particles and sticky substances produced during the crushing of Astragalus are easy to stick to the screen and clog the screen.
[0006] To address the aforementioned problems, this utility model is implemented through the following technical solution.
[0007] A device for ultra-fine pulverization and grading of Astragalus membranaceus, comprising:
[0008] grinder;
[0009] The inner wall of the crusher is provided with a fixing groove, and a screen frame is provided inside the fixing groove. The screen frame is fixed to the wall of the fixing groove.
[0010] The screen frame has rubber parts fixedly connected to the top and bottom of the four inner sides. The two rubber parts on the same side are fixedly connected to the screen mesh located in the middle of the inner side of the screen frame and are adjacent to each other and at the same height.
[0011] Four rectangular slots are provided on the top of the fixed slot on the inner wall of the crusher. The four rectangular slots are respectively opened in the middle of the four inner walls of the crusher. A rotating shaft is fixed inside the rectangular slot. A vibrating rod is rotatably connected to the rectangular slot through the rotating shaft. A torsion spring is installed between the vibrating rod and the rotating shaft.
[0012] The vibrating rod extends from the end away from the rectangular groove to the top of the screen, and a transmission component is fixedly connected to the side near the screen.
[0013] Preferably, a vibration space is formed between the two rubber parts on the same side.
[0014] Preferably, the length of the rectangular groove is less than the length of the fixed groove.
[0015] Preferably, the transmission component is in contact with the screen.
[0016] Preferably, a receiving plate is rotatably connected to the top of one end of the vibrating rod located above the screen, and an elastic element is fixedly connected to the bottom of the receiving plate. The end of the elastic element away from the receiving plate is fixedly connected to the vibrating rod.
[0017] Preferably, the receiving plate is inclined, tilting downwards away from the vibrating rod.
[0018] Preferably, the elastic element is a spring.
[0019] Preferably, the crusher has a feed inlet at the top that extends through itself, and an inclined feed plate is provided at the bottom of the feed inlet. One end of the feed plate is fixed to the inner wall of the crusher, and the other end forms a gap with the inner wall of the crusher. A crushing rotor is rotatably connected to the crusher wall at the bottom of the feed plate. There is at least one crushing rotor, and the crushing rotor is located above the vibrating rod.
[0020] Preferably, the crusher has a discharge ramp at the bottom of the screen frame, the discharge ramp extends to the outside of the crusher to form a discharge port, and a feeder is fixedly connected to the discharge port.
[0021] Preferably, the feeder is connected to a cyclone separator via a pipe, the cyclone separator is connected to a dust collector via a pipe, the dust collector is connected to a fan via a pipe, and the exhaust pipe of the fan is connected to a silencer.
[0022] This invention provides a device for ultra-fine pulverization and grading of Astragalus membranaceus. Compared with the prior art, it has the following advantages:
[0023] 1. By connecting the screen and the rubber parts, when the crushed astragalus powder falls onto the screen, its kinetic energy is transferred to the rubber parts, causing the rubber parts to deform and thus driving the screen to vibrate, effectively reducing screen clogging and improving the screening effect.
[0024] 2. The astragalus powder is collected by the receiving plate. When there is too much astragalus powder at the top of the receiving plate, the tilt angle of the receiving plate increases, and the powder slides onto the screen. On the one hand, the weight of the receiving plate is reduced, and the torsion spring drives the vibrating rod to rotate upward and generate vibration. On the other hand, the vibrating rod transmits the vibration to the screen through the transmission component, further increasing the amplitude and frequency of the screen vibration and improving the screening efficiency.

[0035] Reference Figures 1-6A device for ultra-fine pulverization and grading of Astragalus membranaceus, comprising:
[0036] 10 pulverizers;
[0037] The inner wall of the crusher 10 is provided with a fixing groove 101, and a screen frame 14 is provided inside the fixing groove 101. The screen frame 14 is fixed to the wall of the fixing groove 101.
[0038] The screen frame 14 has four inner sides with rubber parts 15 fixedly connected to the top and bottom. Two rubber parts 15 on the same side are fixedly connected to the screen mesh 16 located in the middle of the inner side of the screen frame 14. The adjacent rubber parts 15 at the same height are connected to each other.
[0039] Furthermore, such as Figure 4 and Figure 5 As shown, the rubber component 15 causes the screen 16 to vibrate.
[0040] Four rectangular slots 102 are provided on the top of the fixed slot 101 on the inner wall of the crusher 10. The four rectangular slots 102 are respectively opened in the middle of the four inner walls of the crusher 10. A rotating shaft is fixed inside the rectangular slot 102. A vibrating rod 17 is rotatably connected to the rectangular slot 102 through the rotating shaft. A torsion spring 174 is installed between the vibrating rod 17 and the rotating shaft.
[0041] Furthermore, such as Figure 4 As shown, the torsion spring 174 drives the vibrating rod 17 to produce a certain vibration.
[0042] The vibrating rod 17 extends to the top of the screen 16 at one end away from the rectangular groove 102, and a transmission component 171 is fixedly connected to the side near the screen 16.
[0043] Furthermore, such as Figure 4 As shown, after the vibrating rod 17 vibrates, it transmits the force to the transmission component 171. The vibration of the transmission component 171 contacts the screen 16, causing the screen 16 to vibrate.
[0044] A vibration space is formed between the two rubber parts 15 on the same side.
[0045] Furthermore, such as Figure 4 As shown, a vibration space is provided for the rubber component 15, thereby increasing the vibration amplitude of the rubber component 15.
[0046] The length of the rectangular groove 102 is less than the length of the fixed groove 101.
[0047] Furthermore, to prevent the vibrating rod 17 inside the rectangular groove 102 from being too large and obstructing the screen 16, thus reducing the working area of the screen 16.
[0048] The transmission component 171 is in contact with the screen 16.
[0049] Furthermore, such as Figure 4As shown, this improves the transmission effect of the transmission component 171 on the screen 16.
[0050] The top of the vibrating rod 17 located above the screen 16 is rotatably connected to a receiving plate 172. The bottom of the receiving plate 172 is fixedly connected to an elastic element 173. The end of the elastic element 173 away from the receiving plate 172 is fixedly connected to the vibrating rod 17.
[0051] Furthermore, such as Figure 6 As shown, the receiving plate 172 is used to collect the falling Astragalus powder.
[0052] The receiving plate 172 is set at an angle, tilting downwards away from the vibrating rod 17.
[0053] Furthermore, such as Figure 4 and Figure 6 As shown, this allows the Astragalus powder on top to fall onto the sieve 16 when the receiving plate 172 vibrates, thereby improving the vibration effect of the receiving plate 172.
[0054] Elastic component 173 is a type of spring.
[0055] Furthermore, while providing bottom support for the receiving plate 172, it also facilitates the receiving plate 172 returning to its initial position after shaking off the astragalus powder on its top.
[0056] The crusher 10 has a feed inlet 11 that passes through it at the top. The bottom of the feed inlet 11 is provided with an inclined feed plate 12. One end of the feed plate 12 is fixed to the inner wall of the crusher 10, and the other end forms a gap with the inner wall of the crusher 10. The bottom of the feed plate 12 is provided with a crushing rotor 13 that is rotatably connected to the wall of the crusher 10. There is at least one crushing rotor 13, which is located above the vibrating rod 17.
[0057] Furthermore, such as Figure 2 As shown, the astragalus material enters from the feed inlet 11 and falls onto the feed plate 12, then slides down the feed plate 12 to the top of the crushing rotor 13. After being crushed by the crushing rotor 13, the astragalus powder falls down onto the screen 16 and the receiving plate 172.
[0058] The crusher 10 has a discharge slope 18 at the bottom of the screen frame 14. The discharge slope 18 extends to the outside of the crusher 10 to form a discharge port, and the discharge port is fixedly connected to the feeder 20.
[0059] Furthermore, such as Figure 1 As shown, the Astragalus powder after being screened by sieve 16 enters the feeder 20 along the discharge slope 18 and the discharge port.
[0060] The feeder 20 is connected to a cyclone separator 30 via a pipe. The cyclone separator 30 is connected to a dust collector 40 via a pipe. The dust collector 40 is connected to a fan 60 via a pipe. The exhaust pipe of the fan 60 is connected to a silencer 50.
[0061] Furthermore, such as Figure 1 As shown, the feeder 20 mixes astragalus powder with air to form a gas-solid two-phase flow, which enters the cyclone separator 30. The cyclone separator 30 utilizes centrifugal force to throw the heavier astragalus powder against the wall of the separator and cause it to fall down and be discharged from the bottom, while the gas containing fine dust is discharged from the top. The dust-laden gas discharged upwards enters the dust collector 40 for further removal of fine dust, thus purifying the gas. The gas purified by the dust collector 40 then enters the silencer 50 and the fan 60 through a pipeline. The silencer 50 reduces the noise generated by the fan 60, and finally, the fan 60 discharges the treated gas.
[0062] Working process and principle: Most of the astragalus powder crushed by the crushing rotor 13 falls downwards onto the screen 16 and the receiving plate 172. During this process, the kinetic energy of the astragalus powder is transferred to the rubber component 15 through the screen 16. The deformation of the rubber component 15 causes the screen 16 to vibrate, improving the screening effect of the screen 16. When there is too much astragalus powder on the top of the receiving plate 172, the tilt angle of the receiving plate 172 increases, and the astragalus powder slides from the top of the receiving plate 172 onto the screen 16, further increasing the vibration amplitude and frequency of the screen 16. At the same time, the overall mass of the vibrating rod 17 connected to the receiving plate 172 decreases. As the torsion spring 174 drives the vibrating rod 17 to rotate upwards, the vibrating rod 17 generates vibration and transmits the force to the screen 16 through the contact between the transmission component 171 and the screen 16, further increasing the vibration amplitude and frequency of the screen 16 and improving the screening effect of the screen 16.
