Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical production, and particularly relates to a forming and drying machine for the production of formula granules. Background Art

[0002] Human health is constantly facing threats from various new diseases, and the medical pharmaceutical industry has emerged as the times require. Pharmaceutical manufacturing refers to the process in which raw materials become new pharmaceutical products through physical or chemical changes, including the manufacture of traditional Chinese and Western medicines commonly mentioned. The pharmaceutical industry is also an industry with high investment, high returns, and high risks. Due to the continuous pressure for innovation in the pharmaceutical industry, pharmaceutical companies must increase their research and development efforts. The forming and drying of pharmaceutical granules is a complex process involving multiple steps and technologies, mainly including processes such as raw material and auxiliary material treatment, granulation, drying, and total mixing. In this process, it is necessary to study the formulation and forming process of the preparation, including the types and dosages of excipients, granulation methods, drying methods, equipment and its technical parameters, finished product yield, and packaging materials.

[0003] Currently, in the forming and drying process of pharmaceutical granules, it refers to drying the formed granule drugs to prevent them from mildewing and deteriorating. However, when existing drying equipment dries granule drugs, usually the granule drugs to be dried are poured into a drying barrel, and hot air is introduced into the drying barrel through a hot air blower or other heating equipment to dry the granule drugs. However, the hot air blower can only dry the drugs on the inner surface of the drying barrel, making the drugs piled up below dry insufficiently. Although some drying equipment also has a stirring structure in the drying barrel to stir the drug granules, the drug granules are unevenly heated during the rolling process, and the drugs rolled to the surface are heated more, while the drug granules at the bottom are heated less, resulting in uneven drying of the granule drugs, thus leading to poor drying effects.

The cylinder 1 is used as a container for drying granular medicines. A feed port is provided on the cylinder 1, and a discharge port is provided at the bottom. When in use, the granular medicines to be dried are fed into the cylinder 1 from the feed port, and the dried granular medicines are sent out of the cylinder 1 from the discharge port; the stirring structure 2 includes a driving member 21, a stirring shaft 22, and a plurality of stirring rods 23. The driving member 21 is arranged in the cylinder 1. The driving member 21 has an output end. The stirring shaft 22 is vertically arranged in the cylinder 1. One end of the stirring shaft 22 is connected to the output end of the driving member 21, and the other end of the stirring shaft 22 is rotatably connected to the inner wall of the cylinder 1. The driving member 21 is used to drive the stirring shaft 22 to rotate. The driving member 21 can be a motor or a servo or other rotating drive structure. The plurality of stirring rods 23 are respectively horizontally arranged on the circumference of the stirring shaft 22. The plurality of stirring rods 23 can rotate the cylinder The granular medicine in the body 1 is stirred to improve the uniformity of drying; the drying structure 3 includes an electric hot air blower 31 and an air supply pipe 32. The electric hot air blower 31 is arranged on the side wall of the cylinder 1. The electric hot air blower 31 can provide hot air to dry the granular medicine. The electric hot air blower 31 has an output end, and one end of the air supply pipe 32 is connected to the output end of the electric hot air blower 31. The stirring shaft 22 and multiple stirring rods 23 are hollow structures, that is, the stirring shaft 22 and multiple stirring rods 23 are hollow rods, and the stirring rod 23 is connected to the stirring shaft 22. Multiple air supply ports 236 are opened on the side wall of the stirring rod 23, and the end of the air supply pipe 32 away from the electric hot air blower 31 is connected to the stirring shaft 22. The air supply pipe 32 sends hot air into the stirring shaft 22, and then the stirring shaft 22 sends it to the granular medicine through the air supply port 236 on the stirring rod 23. When the device is in use, the granular medicine to be dried is fed into the barrel 1 from the feed port, the driving member 21 is started, the stirring shaft 22 is driven to rotate, so that the multiple stirring rods 23 arranged thereon rotate to stir the granular medicine in the barrel 1, and the electric hot air blower 31 is started at the same time, the electric hot air blower 31 supplies hot air to the air supply pipe 32, and the air supply pipe 32 sends the hot air into the multiple stirring rods 23 through the stirring shaft 22, and then the hot air is evenly sent to the stirred granular medicine through the air supply port 236 on the stirring rod 23. In the device, the air supply pipe 32 of the drying structure 3 is connected with the stirring shaft 22 in the stirring structure 2, and the stirring shaft 22 is connected with the multiple stirring rods 23, so that when the stirring shaft 22 drives the stirring rods 23 to rotate, the hot air can be synchronously introduced into the stirred medicine, so that the granular medicines at various places in the barrel 1 can be dried, and the range of the granular medicines in the barrel 1 dried by hot air is expanded, so that the medicine particles can be heated more evenly, and the drying uniformity of the medicine is improved. Among them, a filter screen is fixed on the side wall of each air supply port 236, and the filter hole diameter of the filter screen is smaller than the diameter of the granular medicine. The filter screen can be made of hard plastic or metal material, which can prevent the granular medicine from entering the stirring rod 23 and the stirring shaft 22 through the air supply port 236.

[0039] Furthermore, the air supply pipe 32 is connected to the end of the stirring shaft 22 away from the driving member 21, and a ring plate 321 is fixed to the circumference of the air supply pipe 32. The inner ring of the ring plate 321 is fixed to the circumference of the air supply pipe 32. An annular groove is provided on the inner wall of the stirring shaft 22, and the annular groove is provided along the circumference of the inner wall of the stirring shaft 22. The outer ring side wall of the annular plate 321 is clamped in the annular groove, and the annular plate 321 is slidably connected to the annular groove. When the driving member 21 is working and drives the stirring shaft 22 to rotate, the annular plate 321 slides in the annular groove to avoid driving the air supply pipe 32 to rotate together. Among them, the annular plate 321 can also serve to close the gap between the air supply pipe 32 and the stirring shaft 22.

[0040] Furthermore, the cylinder 1 is a double-layer structure, and the cylinder 1 includes an inner cylinder 11 and an outer cylinder 12. The inner cylinder 11 is inserted into the outer cylinder 12. A plurality of ventilation holes 111 are provided on the side wall of the inner cylinder 11.

One end of the air supply pipe 32 passes through the outer cylinder 12 and the inner cylinder 11 and extends to the stirring shaft 22. The air supply pipe 32 supplies air to the inner cylinder 11. After a long time, the pressure in the inner cylinder 11 increases, and some steam will be generated for drying the medicine. The inner cylinder 11 can be depressurized by opening a plurality of ventilation holes 111. A pressure relief valve 121 is provided on the side wall of the outer cylinder 12. The gas in the inner cylinder 11 flows between the outer cylinder 12 and the inner cylinder 11. The pressure of the outer cylinder 12 can be relieved by providing the pressure relief valve 121.

[0041] Example 2

[0042] As a further improvement scheme based on Example 1, in order to improve the uniformity of drug drying, further, the stirring rod 23 is in a broken line shape, and further includes: a transmission component having an output end and an input end, the input end of the transmission component is connected to the stirring shaft 22, the output end of the transmission component is connected to one end of the stirring rod 23, and the transmission component is used to transmit the rotational motion of the stirring shaft 22 to the rotational motion of the stirring rod 23. In this embodiment, the rotational motion of the stirring shaft 22 can be transmitted to the rotational motion of the stirring rod 23 by setting the transmission component, and the stirring rod 23 is in a broken line shape. When the stirring rod 23 rotates, the granular drugs at the bottom of the cylinder 1 can be turned up to avoid uneven heating of the drugs at the bottom of the cylinder 1, thereby improving the uniformity of drug drying.

[0043] Further, the stirring rod 23 includes: a first rod 231, a second rod 232, and a third rod 233. The first rod 231 is horizontally arranged and relatively short. One end of the first rod 231 is communicated with the stirring shaft 22, and the output end of the transmission assembly is connected to the first rod 231. The transmission assembly is used to drive the first rod 231 to rotate; the second rod 232 is obliquely arranged and can be inclined upward or downward. When the first rod 231 rotates, it will drive the second rod 232 to rotate. One end of the second rod 232 is connected to the other end of the first rod 231; the third rod 233 is horizontally arranged, and one end of it is connected to the other end of the second rod 232. The first rod 231, the second rod 232, and the third rod 233 are of hollow structure to facilitate the transmission of hot air, and the first rod 231, the second rod 232, and the third rod 233 are communicated with each other. A plurality of air supply ports 236 are respectively opened on the side walls of the first rod 231, the second rod 232, and the third rod 233. In this embodiment, the stirring rod 23 is integrally connected by three rod bodies into a broken line shape. When the stirring rod 23 rotates, it can stir up the granular medicine at the bottom of the cylinder 1, avoiding uneven heating of the medicine at the bottom of the cylinder 1 and improving the uniformity of medicine drying. Among them, the angle between the second rod 232 and the axial direction of the stirring shaft 22 is 25°-70°. Because the height of the inner cylinder 11 is certain, if the angle is too small, the third rod 233 will be too long, and if the angle is too large, the third rod 233 will be too short, both of which will affect the range of the granular medicine driven by the flipping. Within this range, when the second rod 232 rotates, the range of the granular medicine at the bottom of the cylinder 1 in the vertical direction is the best.

[0044] Further, a plurality of stirring rods 23 are arranged in a circumferential array around the stirring shaft 22. The plurality of stirring rods 23 in one week form a set of stirring members. According to the height of the cylinder body 1, multiple sets of stirring members can be arranged in the circumferential direction of the stirring shaft 22, so that when the stirring rods 23 in multiple sets of stirring members rotate, the entire height of the cylinder body 1 can be involved, avoiding uneven heating of the granular medicine at the bottom of the cylinder body 1. This embodiment provides a specific structure of a transmission assembly, which includes: a rotating shaft 24, a first bevel gear 25, and a second bevel gear 26. The rotating shaft 24 is sleeved inside the stirring shaft 22. The rotating shaft 24 is relatively thin, and hot air circulates in the gap between the rotating shaft 24 and the stirring shaft 22. One end of the rotating shaft 24 is connected to the output end of the driving member 21. The driving member 21 is used to drive the rotating shaft 24 to rotate. The driving member 21 can drive the rotating shaft 24 and the stirring shaft 22 to rotate. In this embodiment, the driving member 21 is a driving motor. In order to prevent the rotating shaft 24 and the stirring shaft 22 from rotating synchronously, the side wall of the end of the stirring shaft 22 can be connected to the side wall of the output shaft of the driving motor. At the same time, a speed-changing gear set is arranged at the end of the output shaft of the driving motor, and the output end of the speed-changing gear set is connected to one end of the rotating shaft 24, so that the rotating shaft 24 and the stirring shaft 22 rotate non-synchronously, avoiding affecting the movements on the rotating shaft 24 and the stirring shaft 22; the first bevel gear 25 is sleeved and fixed on the circumference of the rotating shaft 24; a plurality of second bevel gears 26 are respectively sleeved and fixed on the circumferences of the first rods 231 among the plurality of stirring rods 23. The first rods 231 are horizontally arranged inside the stirring shaft 22, and the first rods 231 are rotatably connected to the stirring shaft 22. The second bevel gears 26 are located inside the plurality of stirring shafts 22, and the plurality of second bevel gears 26 are respectively meshed with the first bevel gear 25. The working principle of the transmission assembly in this embodiment is that when the driving member 21 works, it drives the rotating shaft 24 to rotate, so that the first bevel gear 25 thereon rotates, driving the plurality of second bevel gears 26 meshed with it to rotate synchronously, thereby driving the first rods 231 to rotate, that is, driving the zigzag stirring rods 23 to rotate, realizing turning up the granular medicine at the bottom of the cylinder body 1.

[0045] Further, a scraping plate 235 is provided at one end of the third rod 233 away from the second rod 232. The scraping plate 235 abuts against the inner wall of the cylinder body 1, and the side wall of the scraping plate 235 is a tip. Since the surface of the granular medicine in the cylinder body 1 may be slightly damp before drying is completed, it is easy to stick to the inner wall of the inner cylinder 11, affecting the uniformity of medicine drying. By providing a scraping plate 235 at one end of the third rod 233 close to the cylinder wall, when the stirring shaft 22 rotates, the adhered medicine on the circumferential direction of the inner wall of the inner cylinder 11 can be scraped off, and at the same time, the stirring rod 23 rotates to scrape off the adhered medicine on the axial direction of the inner wall of the inner cylinder 11. The tip is more convenient for scraping off the adhered medicine.

[0046] Among them, the other structures of this embodiment are the same as those of Embodiment 1, except that it is an optimization of Embodiment 1.

[0047] Embodiment 3

[0048] As a further improvement based on Embodiment 2, in order to involve a larger range of particulate medicines to be flipped when the stirring rod 23 rotates, further, the rotating shaft 24 is a screw rod, and the first bevel gear 25 is threadedly connected to the screw rod in a matching manner, that is, an internal thread is provided on the inner ring of the first bevel gear 25. A plurality of sliding grooves 221 are circumferentially formed on the stirring shaft 22, and the plurality of sliding grooves 221 are arranged in a circumferential annular array on the stirring shaft 22. The sliding grooves 221 are axially formed along the stirring shaft 22. The first rod 231 is inserted into the sliding groove 221, and the movement direction of the first rod 231 is guided by providing the sliding groove 221. When the rotating shaft 24 rotates, on the one hand, it causes the plurality of stirring rods 23 to rotate, and on the other hand, it causes the first bevel gear 25 to move relative to the rotating shaft 24, driving the first rod 231 to rotate and also move in the sliding groove 221, expanding the range where the stirring rod 23 can stir, realizing the drying of the particulate medicines at various positions in the cylinder 1, expanding the range of the particulate medicines dried by hot air in the cylinder 1, enabling the medicine particles to be heated more evenly, and improving the drying uniformity of the medicines.

[0049] In order to prevent the medicine from entering the stirring shaft 22 through the sliding groove 221, further, two springs 222 are provided in the sliding groove 221. The two springs 222 are respectively arranged at both ends of the sliding groove 221. A rotating ring 234 is sleeved on the circumference of the first rod 231, and the rotating ring 234 is rotatably connected to the first rod 231. The rotational connection between the rotating ring 234 and the first rod 231 can be realized through a bearing. When the first rod 231 rotates, it will not drive the rotating ring 234 to rotate. One end of the two springs 222 away from the sliding groove 221 is fixed to the side wall of the rotating ring 234, indicating that the rotating ring 234 is located in the sliding groove 221, and the rotating ring 234 is clamped in the sliding groove 221 and slidably connected to the sliding groove 221. When the first rod 231 rotates, it will not drive the rotating ring 234 to rotate. At the same time, when the first rod 231 is driven to lift in the sliding groove 221, it can drive the rotating ring 234 to move in the sliding groove 221. The two springs 222 are stretched or compressed as the rotating ring 234 rises and falls. The thread coils of the two springs 222 are relatively dense, which can block the sliding groove 221, preventing the medicine from entering the stirring shaft 22 through the sliding groove 221. At the same time, the width of the sliding groove 221 is smaller than the diameter of the medicine, which further prevents the medicine from entering the stirring shaft 22 through the sliding groove 221.

[0050] Among them, the other structures of this embodiment are the same as those of Embodiment 2, except for the optimization made to Embodiment 2.

[0051] The advantage of the present invention is that the device can make the drug particles be heated more evenly and improve the drying uniformity of the drug. Specifically, the device is provided with a stirring structure and a drying structure. The stirring structure can fully stir the granular drugs in the cylinder, and the drying structure can dry the granular drugs in the cylinder. At the same time, the air supply pipe of the drying structure in the device is connected with the stirring shaft in the stirring structure, and the stirring shaft is connected with multiple stirring rods, so that when the stirring shaft drives the stirring rod to rotate, hot air can be synchronously introduced into the stirred drug, so that the granular drugs at various places in the cylinder can be dried, and the range of hot air drying of the granular drugs in the cylinder can be expanded, so that the drug particles can be heated more evenly and the drying uniformity of the drugs can be improved.
