Description

Technical Field

[0001] The present invention relates to the technical field of crushing and pulverizing, and more specifically, the present invention relates to a multi-stage pulverizing system for raw materials used in the production of Yangxin Dingji capsules. Background Art

[0002] When producing Yangxin Dingji capsules, since a large number of medicinal materials are required and extraction or decoction is carried out according to the process, in order to ensure the utilization rate of the medicinal materials and reduce waste, the medicinal residues are usually recycled to ensure that the medicinal components are exhausted. However, the properties of the medicinal residues generated from different medicinal materials are different. Some are sticky, and some contain moisture after decoction and will form lumps after dehydration. If directly mixed and pulverized with new medicinal materials, phenomena such as agglomeration and sticking to the wall are likely to occur. How to solve the problems of agglomeration and sticking to the wall when pulverizing and mixing the medicinal residues and medicinal materials is the technical problem to be solved by the present invention. Therefore, it is necessary to propose a multi-stage pulverizing system for raw materials used in the production of Yangxin Dingji capsules to at least partially solve the problems existing in the prior art.

[0018] When producing Yangxin Dingji Capsules, one of the processes includes first crushing and mixing ginger and cinnamon twig to extract volatile oil, and then obtaining sticky medicinal residues. After soaking red ginseng in warm water for 1 hour, it is decocted twice with water, and after filtration, lumpy medicinal residues containing moisture are obtained.

[0019] It should be noted that if the residue crushing device is not set, in order to ensure the mixing and crushing quality of the mixing and crushing device, without caking and sticking to the wall, it is necessary to fully freeze the two kinds of residues at low temperature and then put them into the mixing and crushing device equipped with refrigeration equipment for low-temperature crushing to avoid caking and sticking to the wall. Although the above method has a relatively high feasibility, it requires additional refrigeration equipment and the residues need to be frozen before crushing. At the same time, it is necessary to ensure that the mixing and crushing device 2 is in a low-temperature state to avoid caking and sticking to the wall. Both the time cost and the production cost will increase.

[0020] Therefore, the preferred implementation method is to first crush the residues through the residue crushing device, fluidize the residues and send them into the mixing and crushing device, fluidize and mix them with the crushed medicinal materials in the mixing and crushing device, and then send them to the next process.

Detailed implementation mode

[0031] The following further elaborates on the present invention in conjunction with the attached drawings and embodiments, enabling those skilled in the art to implement it with reference to the text of the specification.

[0032] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0033] As Figures 1 - 7 shown, the present invention provides a multi-stage crushing system for raw materials used in the production of Yangxin Dingji capsules, including: at least one residue crushing device 1 for crushing agglomerated residues and transporting them to the mixing and crushing device 2;

[0034] The mixing and crushing device 2 is used for crushing unused medicinal materials and fluidizing and mixing them with the crushed residues through gas or liquid, and then sending them to the next process.

[0035] The working principle and beneficial effects of the above technical solution: When producing Yangxin Dingji capsules, one of the processes includes first crushing and mixing ginger and cinnamon twig to extract volatile oil, and then obtaining sticky residues. After soaking red ginseng in warm water for 1 hour, it is decocted twice with water, and after filtration, agglomerated residues containing moisture are obtained. First, the two types of residues are put into the residue crushing device 1 for residue crushing and fluidization treatment, and then sent to the mixing and crushing device 2 to be mixed with crushed medicinal materials such as roasted licorice, mai dong, rehmannia root, Chinese date, and black sesame.

[0036] It should be noted that if the residue crushing device 1 is not set, to ensure the mixing and crushing quality of the mixing and crushing device 2, without agglomeration and sticking to the wall, the two types of residues need to be fully cryogenically frozen and then put into the mixing and crushing device 2 equipped with refrigeration equipment for cryogenic crushing to avoid agglomeration and sticking to the wall. Although the above method is also highly feasible, it requires additional refrigeration equipment, and the residue components need to be frozen before processing. At the same time, it is also necessary to ensure that the mixing and crushing device 2 is in a low-temperature state to avoid agglomeration and sticking to the wall. Both the time cost and production cost will increase.

[0037] Therefore, the preferred implementation is to first crush the medicinal residues through the medicinal residue crushing device 1, fluidize the medicinal residues and send them into the mixing and crushing device 2, fluidize and mix them with the crushed medicinal materials in the mixing and crushing device 2, and then send them to the next process to avoid caking and sticking to the wall.

[0038] In one embodiment, the medicinal residue crushing device 1 consists of an inner tank 12 arranged inside an outer tank 11 and a crushing and conveying device arranged inside the inner tank 12. A gap is reserved between the outer wall of the inner tank 12 and the inner wall of the outer tank 11 to form a fluid channel. A medicinal residue feed inlet 13 is arranged on the outer tank 11. The medicinal residue feed inlet 13 extends to the side wall of the inner tank 12 and is communicated with the inner tank 12. A fluid generator 14 communicated with the fluid channel is arranged on the side wall of the outer tank 11. A plurality of through holes communicated with the fluid channel are arranged on the side wall of the inner tank 12. The diameter of the through holes is smaller than the diameter of the medicinal residue particles. A transport pipe 3 is arranged on the inner tank 12. The transport pipe 3 penetrates through the outer tank 11 and is communicated with the mixing and crushing device 2. The connection part of the transport pipe 3 and the inner tank 12 is adapted to the fluid transport direction of the crushing and conveying device.

[0039] A sealing piece for preventing fluid splashing is arranged on the inner wall of the medicinal residue feed inlet 13.

[0040] When the mixing and crushing device 2 uses gas for fluidized mixing, the fluid generator 14 is a gas source;

[0041] When the mixing and crushing device 2 uses liquid for fluidized mixing, the fluid generator 14 is a water supply device connected to a water supply source.

[0042] The crushing and conveying device includes a driving motor arranged outside the outer tank 11; a driving shaft 15 connected to the driving motor, penetrating through the side wall of the outer tank 11 and extending into the inner tank 12. The rotation central axis of the driving shaft 15 coincides with the central axis of the transport pipe 3; a stirring frame 16 arranged on the driving shaft 15 and fitting with the inner wall of the inner tank 12; and at least one paddle 17 arranged on the driving shaft 15 and located inside the stirring frame 16.

[0043] The working principle and beneficial effects of the above technical solution: Since the medicinal residues have been extracted or decocted in their respective previous processes, they have experienced the crushing process before becoming medicinal residues. Therefore, the role of the medicinal residue crushing device 1 is more to disperse the caked and adhered medicinal residues, and at the same time, it is also necessary to mix and fluidize the dispersed medicinal residues to facilitate the transportation of the medicinal residues to the mixing and crushing device 2, and at the same time, it can also make the mixing of the medicinal residues in the mixing and crushing device 2 more uniform, without adhesion and caking.

[0044] To ensure production efficiency, multiple medicinal residue crushing devices 1 can be set. In this embodiment, only one device is set as an example for illustration.

[0045] First, the sticky medicinal residues (ginger, cinnamon twig) and the water-containing and agglomerated medicinal residues (red ginseng) are jointly fed into the inner tank 12 from the medicinal residue feed inlet 13. A sealing piece for preventing fluid from splashing out is provided on the inner wall of the medicinal residue feed inlet 13. The sealing piece can be made of rubber material, and an opening with central diffusion can be provided on the sealing piece. It should be noted that any shape, structure, and prior art that do not affect the entry of the medicinal residue and can seal the medicinal residue feed inlet 13 can be used as the sealing piece.

[0046] After the medicinal residue enters the inner tank 12, the fluid generator 14 supplies fluid into the inner tank 12 through the fluid channel. The fluid can be gas or liquid. If the supplied fluid is gas, the fluid generator 14 is a gas supply device (gas generation source) such as an air pump that can generate air flow. If the fluid used is liquid, the fluid generator 14 is a water supply device connected to a water source. Whether gas or liquid is selected, the purpose is to fluidize the medicinal residue for easy transportation. At the same time, the fluidized medicinal residue is also used for fluidized mixing in the mixing and crushing device 2. For the convenience of explaining the subsequent embodiments, in this and the subsequent embodiments, liquid is used as the fluidization medium for illustration. Liquid is used as the medium here because in the subsequent process, the crushed and mixed medicinal materials, medicinal residues, and donkey-hide gelatin need to be decocted with water together. Therefore, using water as the medium can reduce the water injection volume in the subsequent process and save production time.

[0047] The liquid enters the inner tank 12 through the circulation holes. Driven by the drive motor, the stirring frame 16 attached to the inner wall of the inner tank 12 can scrape off the medicinal residues sticking to the inner wall of the inner tank 12 and at the same time has the effect of stirring, avoiding the occurrence of flow dead zones in the inner tank 12 and causing the medicinal residues to remain in the inner tank 12. While the stirring frame 16 rotates, the rotation of the paddle 17 will break up and crush the agglomerated and adhered medicinal residues. And the rotation of the paddle 17 promotes the flow of the liquid. Since the direction in which the paddle 17 promotes the flow of the liquid corresponds to the transport pipe 3, as Figure 3 shown, the fluidized medicinal residues after being broken up will directly be transported along the transport pipe 3 into the mixing and crushing device 2. With the power provided by the paddle 3, the fluidized medicinal residues will fluidize and mix the broken medicinal materials in the mixing and crushing device 2.

[0048] In one embodiment, the hybrid grinding device 2 is composed of a cylindrical tank body 21, and a grinding part and a mixing part arranged on the inner wall of the tank body 21; a medicinal material feeding port is arranged at the top of the tank body 21, a discharging port is arranged at the bottom, the discharging port is communicated with the next process, the grinding part is located below the medicinal material feeding port, the mixing part is located below the grinding part, one end of the conveying pipe 3 is communicated with the inner tank 12, the other end is communicated with the side wall of the tank body 21, and the connection part of the conveying pipe 3 and the side wall of the tank body 21 is adapted to the mixing part.

[0049] The grinding part is composed of a cylindrical filter screen 22 with an opening facing the direction of the medicinal material feeding port and a cutting knife 4 driven by a motor. The motor of the cutting knife 4 is selectively arranged at the bottom of the filter screen 22, the cutting knife 4 is located at the top of the filter screen 22, and the cutting knife 4 is composed of five kinds of blades arranged coaxially. The five kinds of blades arranged away from the filter screen 22 are, in order, a side wall scraper 41 with the largest diameter, which is U-shaped and folded upward, and the bent part fits the side wall of the filter screen 22, a bottom scraper 42 bent downward to fit the top surface of the filter screen 22, a large reamer 43 with a diameter smaller than that of the side wall scraper 41, a small reamer 44 with a diameter smaller than that of the large reamer 43, and a stirring knife 45 with a diameter smaller than that of the small reamer 44 and U-shaped and bent upward.

[0050] The mixing part is composed of a sealing plate 23 with a fluid guiding groove 24 on the top surface, a mixer 5 arranged on the sealing plate 23 for mixing medicinal materials and medicinal residues, and at least two shoveling knives 25 connected to the mixer 5 through connecting rods. The connection part of the conveying pipe 3 and the tank body 21 is adapted to the position of the fluid guiding groove 24.

[0051] The mixer 5 is movably connected to the sealing plate 23. A shaft rod is arranged on the mixer 5, the connecting rod is arranged at the top of the shaft rod, and the two shoveling knives 25 are symmetrically arranged at both ends of the connecting rod. The shoveling knives 25 fit the inner wall of the tank body 21 and the bottom surface of the sealing plate 23.

[0052] The mixer 5 is composed of an upper plate part 51 in a frustum shape and a lower plate part 52 arranged on the bottom surface of the upper plate part 51. The upper plate part 51 is located on the top of the sealing plate 23, the lower plate part 52 is located on the bottom of the sealing plate 23. A plurality of spiral ridges are arranged on the side wall of the upper plate part 51, a plurality of discharge holes are arranged on the top surface of the upper plate part 51, and the lower plate part 52 is composed of a plurality of arc-shaped blades connected to the inner wall of the upper plate part 51 and is arranged in a circumferentially uniform manner on the inner bottom wall of the upper plate part 51.

[0053] Working principle and beneficial effects of the above technical solution: The hybrid pulverization device 2 can actually be divided into upper and lower parts. The pulverization part located above is used to pulverize new medicinal materials and ensure the particle size of the medicinal materials falling into the mixing part. The mixing part located below is used to mix and fluidize the pulverized medicinal materials with the fluidized medicinal residues transported through the transport pipe 3. Dividing the hybrid pulverization device 2 into upper and lower parts can effectively prevent water from entering the pulverization part when the fluidization medium is liquid, causing the medicinal materials to stick and block the filter screen 22.

[0054] The tank body 21 is designed in a cylindrical shape, and its connection with the medicinal material inlet is in the shape of a flared mouth that is smaller at the top and larger at the bottom, as Figure 2 , 4 shown. Thus, the filter screen 22 can be set in a cylindrical shape to separate the pulverized medicinal materials from the inner wall of the tank body 21 and avoid sticking to the wall. At the same time, the flared mouth shape that is smaller at the top and larger at the bottom can make the incoming medicinal materials concentrate and fall at the center of the cutting knife 4, so that the medicinal materials can be hit by the stirring knife 45 onto other blades. And the medicinal materials directly falling on the stirring knife 45 can effectively avoid the problem that the sticky medicinal materials roll into balls (such as roasted licorice, jujube, etc. are all sticky) and always roll in the U-shaped part of the stirring knife 45 and cannot be pulverized.

[0055] When the medicinal materials fall, they will first be hit by the stirring knife 45 to both sides to avoid the accumulation of medicinal materials and the formation of sticky balls staying in the U-shaped part of the stirring knife 45. The scattered medicinal materials will be coarsely pulverized by the large reamer 43, and then finely pulverized by the small reamer 44. The medicinal materials sticking to the bottom surface and side wall of the filter screen 22 after fine pulverization can be scraped off by the bottom scraper 42 and the side wall scraper 41 to avoid clogging of the filter screen 22.

[0056] The motor of the cutting knife 4 can be set at the bottom of the filter screen 22, as Figure 4 shown, or it can be set at any position that does not affect.

[0057] After being pulverized by the pulverization part, the medicinal materials fall into the mixing part. The fluidized medicinal residues transported through the transport pipe 3 will be guided by the fluid guiding groove 24 and impact on the mixer 5. The ridges on the upper part 51 of the plate of the mixer 5 will drive the mixer 5 to rotate under the impact of the fluid medicinal materials. While the mixer 5 rotates, it will drive the shovel knife 25 to rotate to remove the settled and sticky medicinal materials or medicinal residues on the top surface of the sealing plate 23 or the side wall of the tank body 21. At the same time, it plays a role in stirring the fluid at the bottom.

[0058] It should be noted that since the upper part 51 of the plate of the mixer 5 is located on the top surface of the sealing plate 23, the lower part 52 of the plate is located on the bottom surface of the sealing plate 23, and the lower part 52 is also connected to the inner wall of the upper part 51, as Figure 6 shown in the cross-sectional view within the square box. Therefore, in actual application, the mixer 5 has two usage methods.

[0059] The first is the above-mentioned movable usage mode. The bottom of the upper part 51 of the plate is placed on the top of the sealing plate 23 and can rotate under the push of the fluid medicinal residues. In this embodiment, the sealing plate 23 needs to have a circular opening for installing and rotating the mixer 5. Under the action of its own gravity, the scraping blade 25 can be attached to the top surface of the sealing plate 23. However, at least 3 to 4 scraping blades 25 need to be provided for support to prevent the scraping blade 25 from getting stuck in the fluid guiding groove 24 during rotation.

[0060] The advantage of this embodiment is that the mixer 5 can rotate under the impact of the fluid medicinal residues. Thus, when the mixed medicinal materials and medicinal residues fall through the discharge port of the upper part 51 of the plate, the rotating mixer 5 can form an air flow through the arc-shaped blades of the lower part 52 of the plate, thereby preventing the fluidized medicinal materials or medicinal residues from atomizing, resulting in the situation where the mixer 5 is stuck and the scraping blade 25 cannot rotate (especially when gas is used as the fluidization medium, the rotating arc-shaped blades can well integrate the flow directions of the fluidized medicinal materials and medicinal residues and avoid dusting). At the same time, the rotating arc-shaped blades can play a role in air extraction, extracting the water mist in the mixing part and preventing the water mist from overflowing back to the pulverizing part.

[0061] The second is the fixed usage mode. That is, the mixer 5 is fixed on the sealing plate 23, and the shaft rod is connected to the connecting rod shaft connecting the scraping blade 25. Thus, the fluid medicinal residues will first impact on the upper part 51 of the plate and generate a swirling flow along the ridges, and the scraping blade 25 is pushed to rotate through the swirling flow.

[0062] The advantage of this embodiment is that the scraping blade 25 rotates more flexibly, has lower requirements for the thrust provided by the fluid medicinal residues, can be set in a smaller number, has less wear on the scraping blade 25, and has a longer service life. However, relatively speaking, because only the swirling flow can generate the thrust for the scraping blade 25 to rotate, the scraping ability of the scraping blade 25 is limited. And the degree of fit between the scraping blade 25 and the top surface of the sealing plate 23 is lower, and it cannot always fit the top surface of the sealing plate 23 like the first embodiment. Since the mixer 5 cannot rotate by itself, for the fluid with liquid as the medium, the lower part 52 of the plate cannot play the role of preventing fogging. Similarly, since the mixer 5 cannot rotate by itself, the above-mentioned air extraction effect cannot be achieved either. Therefore, there may be situations where the water mist overflows back to the filter screen 22, resulting in moisture, caking, sticking, and blockage of the filter screen 22 in the pulverizing part.
