TECHNICAL FIELD
[0001] The present application relates to the technical field of crushing devices, in particular to a traditional Chinese medicinal material crushing device. BACKGROUND
[0002] In the production process of traditional Chinese medicine granules, such as the preparation of common traditional Chinese medicine small granules like Sanjiu Cold Relief Granules, the crushing of traditional Chinese medicinal materials is one of the core processes to ensure product quality. The uniformity of the particle size of the crushed medicinal materials directly affects the stability of subsequent processes such as granulation and drying, and further relates to the dissolution rate, drug release, and taking experience of the finished granules. Currently, traditional traditional Chinese medicinal material crushing devices mostly use a single crushing chamber to centrally process mixed medicinal materials. However, the physical properties of different types of traditional Chinese medicinal materials differ significantly, causing many problems in the crushing process.
[0003] Brittle medicinal materials (such as gypsum and coptis) are hard but have high brittleness, and are easily broken by impact during crushing. Fibrous medicinal materials (such as licorice and ephedra) are rich in fibrous structures and need sustained shearing force to effectively refine them. Adhesive / oily medicinal materials (such as prepared rehmannia and angelica) are prone to adhere to the inner wall of the equipment and the crushing parts due to the presence of mucilage or oil, and are prone to clumping after crushing. When these three types of medicinal materials are mixed and fed into the same crushing device, the equipment needs to be frequently adjusted to meet the crushing requirements of different medicinal materials, resulting in the production of invalid fine powder from brittle medicinal materials due to excessive crushing, insufficient crushing of fibrous medicinal materials due to insufficient shearing force, and the need for additional downtime for cleaning due to the adhesion of adhesive medicinal materials, which seriously affects the continuity of production.
[0004] More importantly, in the mixed crushing mode, the motor needs to maintain high power output at all times to cope with the crushing resistance of different medicinal materials. Even if the crushing requirements of a single type of medicinal material have been met, the motor still needs to consume energy to meet the unmet conditions of other types of medicinal materials. This "one-size-fits-all" crushing method not only causes a great waste of electrical energy, but also increases maintenance costs due to long-term high-load operation of the equipment, which is contrary to the current development needs of energy saving, cost reduction, and efficient production in the pharmaceutical industry.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0030] REFERENCE Figures 1-6The embodiment provides a technical scheme: a traditional Chinese medicinal material crushing device, which comprises a crushing cylinder 100 and a feeding hopper 200 communicated with the top of the crushing cylinder 100, two primary crushing rollers 210 are symmetrically connected in the feeding hopper 200, two first screening plates 240, two second screening plates 230 and two third screening plates 220 are symmetrically arranged from top to bottom on the two sides of the two primary crushing rollers 210, an air nozzle 221 is fixedly connected to the third screening plate 220, a first brush 231 is connected to the end of the second screening plate 230 and abuts against the primary crushing roller 210, a second brush 241 is connected to the end of the first screening plate 240 and abuts against the primary crushing roller 210, and the hardness of the second brush 241 is higher than that of the first brush 231; two partitions 110 are vertically fixedly connected in the crushing cylinder 100, the crushing cylinder 100 is divided into a first crushing cavity 120, a second crushing cavity 130 and a third crushing cavity 140 by the two partitions 110, the fibrous medicinal material is crushed by the primary crushing roller 210 and then falls into the first crushing cavity 120, the brittle medicinal material is blown to the upper part of the third screening plate 220 by the air nozzle 221, and the adhesive medicinal material adhered to the primary crushing roller 210 is scraped off by the first brush 231 and then transmitted to the second crushing cavity 130, and the adhesive medicinal material adhered to the primary crushing roller 210 is scraped off by the second brush 241 and then transmitted to the upper part of the second screening plate 230 and the third crushing cavity 140.
[0031] The crushing cylinder 100 is divided into three crushing cavities by the two partitions 110, the first crushing cavity 120 is used for receiving and further crushing the fibrous medicinal material, the second crushing cavity 130 is used for receiving and further crushing the brittle medicinal material, and the third crushing cavity 140 is used for receiving and further crushing the adhesive medicinal material.
[0032] The primary crushing roller 210 crushes the medicinal material and simultaneously conveys the medicinal material to the direction of the crushing cylinder 100, the fibrous medicinal material in the mixed medicinal material is crushed into small pieces by the primary crushing roller 210, and the small pieces of fibrous medicinal material directly fall into the first crushing cavity 120 through the gap between the two third screening plates 220.
[0033] The brittle medicinal materials are broken into smaller particles by the two primary crushing rollers 210. The air nozzles 221 arranged on the third screening plate 220 blow airflows, so that the smaller particles of the brittle medicinal materials are blown to the upper surface of the third screening plate 220. In addition, part of the brittle medicinal materials are attached to the primary crushing rollers 210, and thus, with the rotation of the primary crushing rollers 210, the first bristles 231 located at the end of the second screening plate 230 can brush the brittle medicinal materials attached to the primary crushing rollers 210 to the upper surface of the third screening plate 220, and then the brittle medicinal materials are transported into the second crushing cavity 130.
[0034] The adhesive medicinal materials are attached to the primary crushing rollers 210 after being broken by the primary crushing rollers 210 due to the adhesion. Since the hardness of the first bristles 231 is lower than that of the second bristles 241, the first bristles 231 cannot scrape the adhesive medicinal materials with a higher degree of adhesion. With the continuous rotation of the primary crushing rollers 210, the adhesive medicinal materials attached to the primary crushing rollers 210 contact the second bristles 241. At this time, the second bristles 241 with higher hardness can scrape the adhesive medicinal materials attached to the primary crushing rollers 210 and drop to the upper surface of the second screening plate 230, and then the adhesive medicinal materials are transported into the third crushing cavity 140.
[0035] Through the above arrangement, the three types of medicinal materials, i.e., fibrous, brittle and adhesive medicinal materials, can be subjected to subsequent crushing treatment respectively, so that the situation that some medicinal materials are excessively crushed and some medicinal materials are insufficiently crushed due to the mixing crushing of the three types of medicinal materials is avoided. In addition, the different types of medicinal materials are subjected to separate crushing, so that the load can be reasonably distributed and the electric energy can be saved.
[0036] The space between the third screening plate 220 and the second screening plate 230 is in communication with the second crushing cavity 130 through a first transmission cylinder 232. The space between the first screening plate 240 and the second screening plate 230 is in communication with the third crushing cavity 140 through a second transmission cylinder 242.
[0037] The two ports of the first transmission cylinder 232 are respectively in communication with the space between the third screening plate 220 and the second screening plate 230 and the second crushing cavity 130. The two ports of the second transmission cylinder 242 are respectively in communication with the space between the first screening plate 240 and the second screening plate 230 and the third crushing cavity 140. In addition, the third screening plate 220 and the second screening plate 230 are both arranged obliquely, so that the medicinal materials dropped on the two screening plates can slide into the corresponding crushing cavities through the corresponding transmission cylinders along the inclination of the screening plates.
[0038] The inner wall of the second transmission cylinder 242 is attached with a rubber belt 400, and the rubber belt 400 is coated with an anti-sticking coating.
[0039] The second transmission cylinder 242 is used for conducting viscous medicinal materials. In order to avoid the viscous medicinal materials adhering to the inner wall of the second transmission cylinder 242, rubber belts 400 are attached to the inner wall in contact with the viscous medicinal materials in the second transmission cylinder 242, and an anti-adhesion coating is applied on the rubber belts 400, so as to ensure the smooth delivery of the viscous medicinal materials.
[0040] The anti-adhesion coating can be a chemical material coating, or talcum powder can be directly applied on the surface of the rubber belts 400. In addition, in order to avoid the viscous medicinal materials adhering to the second brush 241, the first screening plate 240 and the second screening plate 230, talcum powder or an anti-adhesion coating can also be applied on the three components.
[0041] The outer wall of the second transmission cylinder 242 is rotationally connected with a receiving roller 410. One end of the rubber belt 400 is fixedly connected with the inner wall of the port of the second transmission cylinder 242, and the other end is wound on the receiving roller 410. The receiving roller 410 reciprocatingly rotates to switch the rubber belt 400 between the taut and relaxed states, so that the viscous medicinal materials adhering to the rubber belt 400 fall off.
[0042] One end of the rubber belt 400 is fixedly connected with the inner wall of the port of the second transmission cylinder 242, and the other end is received on the receiving roller 410. According to the requirement, it is controlled whether the receiving roller 410 continuously reciprocatingly rotates. If the viscous medicinal materials still adhere to the rubber belt 400, the receiving roller 410 is controlled to continuously reciprocatingly rotate, so that the rubber belt 400 is in the taut and relaxed state change, thereby continuously changing the contact area between the viscous medicinal materials and the rubber belt 400, so that the viscous medicinal materials can fall off the rubber belt 400 and fall into the third crushing cavity 140.
[0043] The receiving roller 410 is driven by a driving device to reciprocatingly rotate. The principle of the above-mentioned rubber belt 400 changing in shape to make the viscous medicinal materials fall off is similar to that of the transparent adhesive tape adhering to the paper. The transparent adhesive tape is pulled at both ends to make the tape change in shape and lengthen, so as to separate the tape from the paper without damaging the paper.
[0044] The pulverizing cylinder 100 is rotationally connected with a rotating cylinder 330. The rotating cylinder 330 is composed of a first cylinder body 331, a second cylinder body 332 and a third cylinder body 333 which are coaxially rotationally connected from top to bottom. The first cylinder body 331 is located in the first crushing cavity 120 and is connected with a first crushing blade 3311 on the side wall. The second cylinder body 332 is located in the second crushing cavity 130 and is connected with a second crushing blade 3321 on the side wall. The third cylinder body 333 is located in the third crushing cavity 140 and is connected with a third crushing blade 3331 on the side wall.
[0045] The first cylinder body 331, the second cylinder body 332 and the third cylinder body 333 constituting the rotating drum 330 rotate in the first crushing cavity 120, the second crushing cavity 130 and the third crushing cavity 140 respectively, the first crushing blade 3311 connected to the first cylinder body 331 has a thin blade body and a "sawtooth" or "wavy" blade edge, the sawtooth interval is small (1-2mm), the tooth tip is sharp, and the fiber bundle is cut through the "interlaced shearing" of the sawtooth when rotating;
[0046] The second crushing blade 3321 connected to the second cylinder body 332 has a larger blade body thickness, the blade edge is not sharp and acute, but is "obtuse-angled" (blade edge angle 90°-120°), and the medicinal materials are broken through "rigid impact" rather than shearing force when rotating (brittle medicinal materials can be broken without sharp blade edge);
[0047] The third crushing blade 3331 connected to the third cylinder body 333 has a polished blade body surface, which reduces the contact area and friction force of the material with the blade surface, the blade body can be coated with Teflon (PTFE) or ceramic plating, which uses the low surface energy characteristics to prevent the adhesion of mucus and oil, the blade edge is "shallow arc" rather than right angle, which avoids the accumulation of materials in the corner of the blade edge, in addition, a refrigerant medium can be introduced into the cavity side wall of the third crushing cavity 140, so that the viscous medicinal materials are crushed in a low temperature state.
[0048] The driving shaft 320 is inserted into the rotating drum 330, the first sliding key 321, the second sliding key 322 and the third sliding key 323 are sequentially arranged on the side wall of the driving shaft 320 from top to bottom, and the first cylinder body 331, the second cylinder body 332 and the third cylinder body 333 are respectively provided with key grooves matched with the first sliding key 321, the second sliding key 322 and the third sliding key 323.
[0049] The driving shaft 320 is inserted into the rotating drum 330, and the rotating drum 330 is driven to rotate by the key matching mode, so as to classify and crush the medicinal materials.
[0050] The first cylinder body 331, the second cylinder body 332 and the third cylinder body 333 are respectively provided with the first annular groove 3211, the second annular groove 3221 and the third annular groove 3231 below the corresponding key grooves, the second sliding key 322 is shorter than the first sliding key 321, and the first sliding key 321 is shorter than the third sliding key 323, so that when the driving shaft 320 moves downward, the second cylinder body 332 stops rotating first, the first cylinder body 331 stops rotating subsequently, and the third cylinder body 333 stops rotating last.
[0051] The arrangement of the three annular grooves makes the downward movement of the driving shaft 320 not be interfered. Since the required time for crushing the fibrous, brittle and viscous medicinal materials is different, the crushing speed of the brittle medicinal material is the fastest, the crushing speed of the fibrous medicinal material is the second, and the crushing speed of the viscous medicinal material is the last. Therefore, when the medicinal materials are crushed, the driving shaft 320 slides downward relative to the rotating drum 330, so that the second sliding key 322 first completely enters the second annular groove 3221, at this time the second cylinder body 332 first stops rotating, so that the crushing of the brittle medicinal material is stopped, the driving shaft 320 continues to slide downward, the first sliding key 321 then completely enters the first annular groove 3211, at this time the first cylinder body 331 then stops rotating, so that the crushing of the fibrous medicinal material is stopped, and the driving shaft 320 slides downward again, the third sliding key 323 finally completely enters the third annular groove 3231, at this time the crushing of the viscous medicinal material is stopped.
[0052] Through the above arrangement, the rotating load of the driving shaft 320 is reduced, the driving force is reasonably distributed, and the electric energy is saved.
[0053] The lower surface of the crushing cylinder 100 is fixedly connected with two air cylinders 311 in a symmetrical manner, the cylinder bodies of the two air cylinders 311 are fixedly connected with a base 310 in a common manner, the base 310 is fixedly connected with a motor 300, and the driving shaft 320 is fixedly connected to the output end of the motor 300.
[0054] The extension and retraction of the air cylinder 311 can drive the motor 300 to approach or move away from the bottom wall of the crushing cylinder 100, so that the driving shaft 320 slides in the rotating drum 330, and the driving force of the three cylinder bodies is gradually cancelled. The extension and retraction of the air cylinder 311 can also be set to start at a fixed time, or the driving load of the motor 300 can be monitored through current or voltage feedback to know the crushing degree and then operate.
[0055] Further comprising a fixedly arranged hinged seat 520, the sidewall bottom of the crushing cylinder 100 is fixedly connected with two rotating shafts 510 in a symmetrical manner, the two rotating shafts 510 are rotatably connected to the two hinged seats 520 respectively, the outer wall of the crushing cylinder 100 located in the middle of the two hinged seats 520 is hingedly connected with two hydraulic rods 500 on both sides, and one end of the hydraulic rod 500 away from the crushing cylinder 100 is fixedly arranged.
[0056] The two hydraulic rods 500 are arranged in an operating state that one is elongated and the other is shortened, so that the crushing cylinder 100 can swing, and then the internal medicinal materials can move, increasing the contact between the medicinal materials and the crushing blades.
[0057] The first crushing cavity 120, the second crushing cavity 130 and the third crushing cavity 140 are all communicated with a discharge pipe 101, and the discharge pipe 101 is provided with a valve.
[0058] Three broken cavities are communicated with discharge pipes 101, when the crushing is completed, control two hydraulic rods 500 to make the crushing cylinder 100 tilt, and then open the valves on the three discharge pipes 101, so that the crushed medicinal materials in the crushing cylinder 100 are discharged.
[0059] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
