Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, and in particular to an efficient high-temperature mixing granulation device for traditional Chinese medicine and a granulation method thereof. Background Art

[0002] Chinese medicine extrusion granulation technology is an important technology in the modernization process of Chinese medicine preparations. It is based on traditional Chinese medicine slices and uses modern technology to achieve the extraction, separation, concentration and granulation of Chinese medicine ingredients. This technology not only retains the efficacy of traditional Chinese medicine, but also greatly facilitates the use of patients and improves the convenience and safety of medication.

[0003] In the patent entitled "Extrusion granulation equipment and Chinese medicinal material granulation process" and with publication number CN118162048B, it is proposed that in order to control the size of the particles during use of the current rotary granulator, an annular knife holder is arranged outside the rotating screen, and a plurality of scrapers that fit the screen are fixed on the knife holder. This can control the particle size and prevent the adhesion of sticky particles. However, there are still certain problems: first, when the material is viscous, the material is easy to adhere to the edge of the scraper and gradually accumulate into large pieces. If large pieces are formed, neither manual cleaning nor natural falling off will meet the particle size requirements; secondly, when the sticky particles fall from the screen to the discharge plate of the granulator, they are also easy to adhere to the discharge plate, resulting in material accumulation and uneven discharge. The drive component is used to control the intermittent alternating movement of the scrapers on the two cleaning components, and one of the scrapers is used to clean the particles on the screen when it is stationary. The other scraper is used to clean the particles accumulated on the surface of the stationary scraper when it is active. The two scrapers operate alternately and cooperate with each other, which avoids the formation of large lumps of particles accumulated on the scraper, thereby ensuring the quality of granulation. There is no need for manual cleaning, which is more convenient and efficient. However, the scraper needs to rotate one circle each time it rotates to scrape off the material on the outside of the screen before it can be re-attached to the outside of the filter. This results in the phenomenon that it cannot scrape continuously when cleaning and scraping off the material. The overall scraping speed is slow, and the direction of the scraper needs to be changed each time the other scraper is cleaned so that it works alternately. However, during the alternating rotation and bonding process, it is necessary to ensure that the edges of the two scrapers are always attached together. Once the angle is wrong, the scraper will still be unable to clean the external attachments in time. Therefore, the present application proposes an efficient high-temperature mixing granulation device for traditional Chinese medicine and a granulation method thereof. Summary of the invention

[0004] The object of the present invention is to provide an efficient high-temperature mixing granulation device for Chinese medicinal materials and a granulation method thereof, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: Figure 1-Figure 4As shown, the present application is an efficient high-temperature mixing granulation device for Chinese medicinal materials, including a granulator body 100, the granulator body 100 is connected to a screen 101, the outside of the screen 101 is installed with a knife holder 113 through a plurality of supporting legs, the inner wall of the knife holder 113 is fixedly connected with four groups of mounting frames 102, each group of mounting frames 102 is rotatably connected with a second support rod 114 and a first support rod 103, the outside of the first support rod 103 is fixedly connected with a first connecting tube 104, the outside of the second support rod 114 is fixedly connected with a second connecting tube 106, the first connecting tube 106 is fixedly connected with a second connecting tube 107, and the second connecting tube 108 is fixedly connected with a second connecting tube 109. A plurality of first scrapers 105 are integrally formed on the outside of the connecting tube 104, a second scraper 107 is integrally formed on the outside of the second connecting tube 106, the top ends of the first support rod 103 and the second support rod 114 penetrate the outer wall of the mounting frame 102 and are connected to a driving structure, a discharge plate 115 is movably connected at the discharge port of the screen 101, the first scraper 105 adheres to the outer wall of the screen 101 during rotation and is used to clean particle attachments on the outside of the screen 101, and the second scraper 107 is used to clean attachments stuck to the outside of the first scraper 105 during rotation.

[0036] Specifically, during use, the staff places the raw materials of traditional Chinese medicine into the screen 101. After the raw materials enter the screen 101, the screen 101 will transport part of the raw materials into the granulator body 100. After the raw materials are transported into the granulator body 100, the granulator body 100 will perform high-temperature mixing on the Chinese medicinal materials. After the high-temperature mixing is completed, the extrusion function is started to extrude the high-temperature mixed materials through the mesh holes outside the screen 101.

[0037] Furthermore, during the extrusion process, the material continuously generates pressure through the inside of the granulator body 100 and is extruded through the mesh holes outside the screen 101. During the extrusion process, the staff can start the driving structure to drive the first support rod 103 and the second support rod 114 to rotate clockwise. When the first support rod 103 and the second support rod 114 rotate, the first connecting cylinder 104 and the second connecting cylinder 106 can be driven to rotate. In the process of the first connecting cylinder 104 driving the multiple first scrapers 105 to rotate clockwise, the multiple first scrapers 105 will be attached to the outer wall of the screen 101 away from the side of the first connecting cylinder 104. When the first scraper 105 adheres to the outer wall of the screen 101 and rotates, the raw material extruded from the mesh holes outside the screen 101 can be scraped off, and the multiple first scrapers 105 can continuously scrape the raw materials in the mesh holes driven by the first connecting cylinder 104, thereby realizing continuous operation of scraping off the raw materials.

[0038] Furthermore, when multiple first scrapers 105 continue to scrape the raw materials in the mesh, some raw materials will remain at the edges of the multiple first scrapers 105. The presence of these raw materials will greatly affect the molding degree of the material during extrusion and scraping. When the material at the edge of the first scraper 105 is excessively adhered to form a large adhesion deposit, the first scraper 105 will squeeze the material when scraping the material in the mesh of the screen 101, causing the material to be shapeless or unable to be extruded through the screen 101. Therefore, in the process of the first connecting cylinder 104 driving the first scraper 105 to rotate, the second connecting cylinder 106 and the second scraper 107 can also be driven by the driving structure to rotate clockwise. When the first scraper 105 rotates, the second scraper 107 that also rotates clockwise will fit the outer wall of the first scraper 105, so that in the process of the first scraper 105 scraping the material, the second scraper 107 on the other side that continues to contact the first scraper 105 is used to scrape off the attached material stuck to the outside of the first scraper 105, thereby ensuring the cleanliness of the outside of the first scraper 105.

[0039] like Figure 1-Figure 12 As shown, the driving structure includes four driving motors 111 and four auxiliary motors 116, and the four driving motors 111 and the four auxiliary motors 116 are respectively fixedly connected to the outside of the four groups of mounting frames 102, the output shaft of the driving motor 111 is fixedly connected to the driving pulley 112, the top of the second support rod 114 passes through the outside of the mounting frame 102 and is fixedly connected to the driven pulley 110, the top of the first support rod 103 passes through the outer wall of the mounting frame 102 and is fixedly connected to the driving gear 109, the outside of the mounting frame 102 is integrally formed with an L-shaped connecting seat, the auxiliary motor 116 is fixedly connected to the L-shaped connecting seat, the output shaft of the auxiliary motor 116 passes through the outer wall of the L-shaped connecting seat and is fixedly connected to the driven gear 108, the driven gear 108 and the driving gear 109 are meshed and connected, and the driven pulley 110 and the driving pulley 112 are connected by belt transmission.

[0040] Specifically, in the driving structure, the staff can drive the active pulley 112 connected to the output shaft of the driving motor 111 to rotate by turning on the four driving motors 111. In the process of driving the active pulley 112 to rotate, the active pulley 112 will drive the driven pulley 110 to rotate clockwise through the belt, and the rotation of the driven pulley 110 will drive the second support rod 114 to rotate clockwise, and the rotation of the second support rod 114 will drive the second connecting cylinder 106 and the second scraper 107 to rotate clockwise, and at the same time start the auxiliary motor The machine 116 drives the driven gear 108 to rotate clockwise, and the rotation of the driven gear 108 drives the driving gear 109 to rotate clockwise, and the clockwise rotation of the driving gear 109 drives the first support rod 103 to rotate clockwise, and the clockwise rotation of the first support rod 103 drives the first connecting tube 104 to rotate clockwise, and the rotation of the first connecting tube 104 drives the first scraper 105 to rotate clockwise, and the continuous clockwise rotation of multiple first scrapers 105 can scrape off the material continuously squeezed out of the outside of the screen 101.

[0041] like Figure 1-Figure 3 As shown, the bottom end of the first support rod 103 passes through the outer wall of the tool holder 113 and is rotatably connected to the granulator body 100. The outside of the first support rod 103 is fixedly connected to a connecting plate 500, and a collision block 501 is fixedly connected to the connecting plate 500. The connecting plate 500 and the collision block 501 are located below the unloading plate 115.

[0042] Specifically, during use, the material falls into the blanking plate 115 through the outlet of the tool holder 113 after extrusion is completed. When the material with a certain viscosity falls inside the blanking plate 115, it will cause a certain amount of material accumulation. When the material continues to accumulate, it will cause the outlet of the tool holder 113 to be blocked. In the process of continuous rotation of the first support rod 103, the connecting plate 500 can be driven to rotate. The rotation of the connecting plate 500 will drive multiple impact blocks 501 to continuously impact the blanking plate 115, so that the blanking plate 115 continues to vibrate through the impact force, thereby avoiding blockage in the channel connecting the blanking plate 115 and the tool holder 113.

[0043] Furthermore, when the connecting plate 500 continues to rotate, it will drive the impact block 501 to enter the bottom of the blanking plate 115. After the impact block 501 enters the bottom of the blanking plate 115, it will lift up the blanking plate 115, and after lifting up the blanking plate 115, the continuous rotation of the connecting plate 500 will drive the impact block 115 to move out from the bottom of the blanking plate 115, so that the blanking plate 115 falls after being lifted up, and further causes the blanking plate 115 to vibrate. A plurality of elastic telescopic rods 601 are fixedly connected to the bottom of the blanking plate 115, and the blanking plate 115 is supported by the arrangement of the plurality of elastic telescopic rods 601. At the same time, the elastic telescopic rods 601 can further strengthen the shaking generated when the blanking plate 115 is lifted up and falls when supporting the blanking plate 115.

[0044] Furthermore, a rubber seat 600 is integrally formed at the bottom of the blanking plate 115, and the top of the impact block 501 is spherical and made of rubber. When the top of the impact block 501 is spherical, the spherical curved surface can be used to smoothly move into the bottom of the blanking plate 115 during the rotation of the connecting plate 500. At the same time, when the impact block 501 hits the outside of the rubber seat 600, it will not generate excessive noise, and the blanking plate 115 will be buffered at the same time.

[0045] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, during the extrusion of the material, the driving structure is utilized to drive the first connecting cylinder 104 and the first scraper 105 to rotate. When the first scraper 105 is continuously rotating, the material outside the screen 101 can be continuously scraped off, and continuous scraping can be achieved. At the same time, during the continuous scraping process, the second support rod 114 will drive the second connecting cylinder 106 and the second scraper 107 to rotate. The first scraper 105 is continuously cleaned by the rotation of the second connecting cylinder 106 and the second scraper 107, so as to ensure the cleaning of the first scraper 105 under the condition of continuous scraping and avoid the situation where the material sticks to the outside of the first scraper 105.

[0046] Embodiment 2: Considering that during use, when the first scraper 105 scrapes off the material on the screen 101, part of the material may adhere to the side wall of the first scraper 105, and when the second scraper 107 scrapes and cleans the outer wall of the first scraper 105, some tiny raw material residues may adhere to the side wall of the first scraper 105 due to inadequate adhesion. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0047] like Figure 4As shown, the first scraper 105 and the second scraper 107 are arc-shaped. The arc-shaped first scraper 105 is used to fit the outer wall of the screen 101 and snap inward to scrape off the raw material remaining on the outer wall of the screen 101. The arc-shaped second scraper 107 is used to fit the first scraper 105 which is also arc-shaped and snap inward to scrape off the raw material remaining on the outer wall of the first scraper 105. The first scraper 105 and the second scraper 107 are made of elastic material.

[0048] Specifically, during use, the first scraper 105 in an arc shape fits the filter holes on the outer wall of the screen 101, so as to scrape the raw materials squeezed out of the mesh holes of the screen 101, and after the first scraper 105 scrapes the raw materials from the screen 101, the first scraper 105 rotated to the other side will gradually contact with the second scraper 107, and in the process of gradually contacting with the second scraper 107, the arc-shaped second scraper 107 can be more closely fitted to the first scraper 105 which is also arc-shaped, and at the same time, the second scraper 107 can extend the arc-shaped second scraper 107 in the process of scraping one side of the first scraper 105. The arc surface of a scraper 105 is gradually scraped from the deep end toward the outer side of the arc surface to enhance the overall scraping and cleaning effect. At the same time, the hardness of the second scraper 107 is greater than that of the first scraper 105. When the second scraper 107 scrapes the first scraper 105, the first scraper 105 will bend and deform due to the extrusion of the second scraper 107, and when the second scraper 107 is gradually offset from the first scraper 105 under the drive of the second connecting tube 106, the squeezed and deformed second scraper 107 can immediately rebound to its original state, and the inertial force generated by the rebound can again shake off some of the attachments adhered to the outer side of the first scraper 105.

[0049] like Figure 1 and Fig.13 As shown, a magnetic plate 801 is fixedly connected to the outside of the mounting frame 102, and a plurality of iron adsorption blocks 800 are fixedly connected to the outside of the first scraper 105. The magnetic plate 801 is located on one side of the first connecting tube 104. When the first connecting tube 104 drives the first scraper 105 and the iron adsorption block 800 to rotate clockwise until they are close to the magnetic plate 801, the first scraper 105 is driven by the iron adsorption block 800 to approach the position of the magnetic plate 801. When the first scraper 105 approaches the position of the magnetic plate 801 through the iron adsorption block 800, a bending deformation opposite to its own arc shape will be generated. When the first connecting tube 104 continues to rotate clockwise, the deformed first scraper 105 will break away from the attraction range of the magnetic plate 801 and recover to its original state through its own elasticity. When it recovers to its original state, the inertia generated by the rebound drives the iron adsorption block 800 to impact the second scraper 107 that is rotating clockwise, and the impact on the outside of the second scraper 107 generates vibration.

[0050] Specifically, during use, in order to ensure the cleanliness of the second scraper 107, a magnetic plate 801 is installed on one side of the first scraper 105, and the magnetic plate 801 attracts the iron adsorption block 800, so that the first scraper 105 close to the magnetic plate 801 produces a reverse bending deformation. After the reverse bending deformation occurs, the deformed first scraper 105 will leave the attraction range of the magnetic plate 801 and recover to its original state through its own elasticity. When it returns to its original state, the inertia generated by the rebound drives the iron adsorption block 800 to collide with the second scraper 107 that is rotating clockwise, and the outside of the second scraper 107 is impacted to generate vibration. The first scraper 105 with multiple iron adsorption blocks 800 on the outside impacts the second scraper 107, so that the second scraper 107 is cleaned through a certain impact and vibration, thereby reducing the attachments on the outside of the second scraper 107.

[0051] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, by changing the shape of the first scraper 105 and the second scraper 107 into an arc shape, when the first scraper 105 scrapes the material outside the mesh, only the outer edge has partial contact, thereby reducing the situation where a large amount of material adheres to the outer wall of the first scraper 105. At the same time, the arc-shaped second scraper 107 can be interlocked with the first scraper 105, and the outer wall of the first scraper 105 can be scraped and cleaned during continuous rotation, so the fitting effect is better and the scraping of the first scraper 105 is cleaner.

[0052] Embodiment 3: Considering that when too much raw material has accumulated outside the first scraper 105, the first scraper 105 and the second scraper 107, which are arc-shaped but vertical to each other, will squeeze part of the material when in contact with each other, and the originally extruded material is already viscous, it is easy to be directly flattened and adhered to the outside of the scraper after the second extrusion. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0053] like Figure 1-Figure 6 As shown, the first scraper 105 and the second scraper 107 are spiral-shaped. The spiral first scraper 105 is used to adhere to the outer wall of the screen 101 and scrape off the residual raw materials on the outside of the screen 101 during the rotation process. After scraping off the residual raw materials, the residual raw materials will roll down obliquely through the spiral first scraper 105, thereby forming agglomerates and adhering to more residues in the process of rolling down. The spiral second scraper 107 is used to scrape off the residues adhered to the outside of the first scraper 105 from bottom to top when in contact with the first scraper 105.

[0054] Specifically, during use, in order to prevent the second scraper 107 from causing secondary extrusion and adhesion when cleaning the residue on the outside of the first scraper 105, the first scraper 105 and the second scraper 107 are set in a spiral shape. When the first scraper 105 is set in a spiral shape, it can not only scrape off the residual raw materials on the outside of the screen 101 during the rotation process, but also after the residual raw materials are scraped off, the residual raw materials will roll down obliquely through the spiral first scraper 105, thereby forming agglomeration and adhesion of more residues in the process of rolling down. After the raw materials are completed, they will meet the second scraper 107 which is also spiral. After the second scraper 107 which is also spiral meets the first scraper 105, because of the different spiral directions and the second scraper 107 having a harder surface than the first scraper 105, the second scraper 107 will gradually fit toward the top of the first scraper 105 from bottom to top, and scrape the outer wall of the first scraper 105 from bottom to top, so as to avoid the situation where the first scraper 105 and the second scraper 107 fit together and squeeze the residue to cause secondary adhesion when there are too many residues on the outside of the first scraper 105 in an upright state.

[0055] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, by setting the first scraper 105 and the second scraper 107 to be spirally shaped, the scraping can be performed from bottom to top during the scraping process of the first scraper 105 by the second scraper 107, thereby avoiding the first scraper 105 and the second scraper 107 from sticking to each other and squeezing the residual attachments, thereby avoiding the phenomenon of secondary adhesion.

[0056] Embodiment 4: Considering that after the second scraper 107 scrapes the residue outside the first scraper 105 during actual use, the residue is likely to remain on the second scraper 107. When the residue continues to adhere to the second scraper 107, it is easy to affect the scraping effect of the first scraper 105. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0057] like Figure 7-Figure 8 As shown, a through groove 200 is provided on the outside of the spiral second scraper 107, and the through groove 200 is used to discharge the residue to a position outside the second scraper 107 through the through groove 200 when the spiral second scraper 107 scrapes the residue from bottom to top. A through groove 200 is provided on the outside of the second scraper 107, and the through groove 200 is used to discharge the residue to a position outside the second scraper 107 through the through groove 200 when the spiral second scraper 107 scrapes the residue from bottom to top.

[0058] Specifically, the through groove 200 opened can make the second scraper 107 present a spiral frame shape, so that when scraping the outside of the first scraper 105 from bottom to top, the residue adhering to the outside of the second scraper 107 can be reduced, and the second scraper 107 on the outside of the through groove 200 can scrape the residue, and the scraped residue will fall to the bottom through the through groove 200.

[0059] Furthermore, an elastic sheet 300 is fixedly connected to one side of the inner wall of the through groove 200, and a counterweight block 400 is fixedly connected to one side of the elastic sheet 300. The setting of the elastic sheet 300 can prevent the residue from passing through the through groove 200 and falling back onto the outer wall of the first scraper 105 when the second scraper 107 scrapes off the residue, and the inertia generated when the second scraper 107 and the first scraper 105 are separated from each other can drive the elastic sheet 300 to vibrate continuously, thereby shaking off the residual raw materials attached to the outside of the elastic sheet 300 and the second scraper 107, and the vibration generated by the elastic sheet 300 being subjected to the inertial impact force is further strengthened by the external counterweight block 400.

[0060] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the third embodiment, in the present embodiment, by means of the through groove 200 and the setting of the elastic sheet 300, after the second scraper 107 scrapes off the residue on the outside of the first scraper 105, the residue can be gradually shaken off by the vibration generated and the gap of the through groove 200, thereby preventing the residue from adhering to the outside of the second scraper 107 and affecting the scraping and cleaning of the first scraper 105 by the second scraper 107.

[0061] Embodiment 5: Considering that during use, when the overall granulator is stopped for a period of time, the attachments that adhere to the outside of the first scraper 105 and are not scraped off in time may harden. In the case of hardening, the semi-hard second scraper 107 cannot effectively scrape off the attachments that have adhered to the first scraper 105 and hardened. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0062] like Figure 7-Figure 13 As shown, a cavity is opened inside the second scraper 107 and the second connecting tube 106, and the cavity is filled with electrorheological fluid 701. The electrorheological fluid 701 is connected to a conductive wire 702. The power-carrying end of the conductive wire 702 passes through the outer wall of the second scraper 107 and is connected to a wireless power supply 700.

[0063] Specifically, during use, when the overall granulator is shut down for a period of time, the staff transmits current to the conductive wire 702 through the wireless communicator 700. When the current passes through the conductive wire 702, the conductive wire 702 will divert the current to the inside of the electrorheological fluid 701. When the current is transmitted to the inside of the electrorheological fluid 701, the electrorheological fluid 701 will harden, and after hardening, it will drive the second scraper 107 to harden as a whole. After hardening, the hardened attachments can be scraped off.

[0064] The present invention also provides a granulation method of an efficient Chinese medicinal material high-temperature mixing granulation device, comprising the following steps:

[0065] S1, placing the material inside the screen 101, and starting the granulator body 100 to press the material inside the screen 101, so that the material is squeezed through the mesh outside the screen 101 to form particles;

[0066] S2, after the material passes through the screen 101 to form particles, the driving structure is started to drive the first scraper 105 to scrape off the particles squeezed out of the screen 101, and to scrape off the residues attached to the outside of the screen 101;

[0067] S3. After the first scraper 105 scrapes off the particles and residues, the second connecting tube 106 drives the second scraper 107 to continue scraping off the residues on the outside of the first scraper 105 to prevent the materials from adhering to the outer wall of the first scraper 105.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
