[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0043] It should be noted that in the appendix of the manual Figure 1 In the present disclosure, the directions or positions indicated by "upper" and "lower" are based on the directions or positions shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides a highly enclosed small-batch integrated pharmaceutical system, including a main body shell 12 and a material bin 5 arranged on the main body shell 12. The system delivers the material into the material bin 5 through the feeding component, and then the material bin 5 mixes the material with the slurry. After the slurry and the material are fully mixed, they adhere to each other to form fine particles, which boil under the negative pressure generated by the exhaust fan 206, and are heated to form relatively compact large particles. In addition, the above processes are all completed above the bottom screen 27. When the material forms large particles, it needs to be discharged through the bottom screen 27. Specifically, the bottom screen 27 is set to be rotatable. When it rotates, a gap is formed between the bottom screen 27 and the material bin 5, and the material falls through the gap under the action of its own gravity. Of course, the rotation angle of the bottom screen 27 can be adjusted according to actual conditions to control the falling speed of the material.

[0045] In addition, since the granules produced by the above process are not uniform in size, the granule size is adjusted by the dry granulation assembly 7, such as Figure 8 As shown, specifically, the dry granulation component 7 includes a dry granulation knife 32 and a granulation screen 34. The dry granulation knife 32 quickly cuts the particles to obtain a suitable particle size, and then the particles pass through the granulation screen 34 and fall into the discharging component to complete the discharging.

[0046] Specifically, the dry granulation knife 32 is installed on the upper end of the granulation screen 34, and the dry granulation knife 32 is connected to the granulation power system through the reverse thread nut 33; in the granulation process, the dry granulation knife 32 is first turned on, the appropriate speed is selected, and the handle 17 is manually opened to drive the rotating bottom screen 27, and the particles enter the dry granulation component 7, thereby achieving rapid cutting of the particles; since the particle size of the particles formed during the drying process is inconsistent, the appropriate particle size can be obtained after dry granulation; the size of the granulation screen 34 can be changed according to the material properties and the final particle size, so as to better achieve the later process production goals.

[0047] It should be noted that a feed port is provided on the material bin 5, and a manual valve is provided on the feed port. The manual valve is externally connected to a feed assembly. Specifically, the manual valve is connected to the feed pipe 4, a feed valve B2 is provided at the bottom of the distributor, and a feed valve A3 is provided at the end of the feed pipe 4. The feed valve A3 and the feed valve B2 are used in conjunction with each other; during the feeding process, the feed valve B2 and the feed valve A3 installed at the lower end of the powder barrel 1 are manually docked, and the feed valve B2 and the feed valve A3 are manually opened. A communicating channel is formed inside the feed valve B2 and the feed valve A3, and the material can pass through the feed pipe 4 and enter the pot body under the action of the negative pressure generated by the exhaust fan 206; the feed valve B2 and the feed valve A3 are closed, and the communicating channel is closed by the feed valve B2 and the feed valve A3. The docking of the feed valve B2 and the feed valve A3 is manually disassembled, the powder barrel 1 is removed, and the feed manual valve 15 is closed at the same time to complete the feeding process. The entire feeding process is completely sealed.

[0048] In addition, if Figure 5 and Figure 7 As shown, the bottom screen 27 is arranged along the radial cross-section of the material bin 5, and the material in the material bin 5 is located above the bottom screen 27. A rotating shaft 26 is arranged on the edge of the bottom screen 27. The rotating shaft 26 passes through the outer wall of the material bin 5 and is rotatably arranged on the material bin 5. The end of the rotating shaft 26 away from the bottom screen 27 extends out of the material bin 5 and is provided with a handle 17. The handle 17 is provided with a plurality of positioning holes 31 passing through it, and a positioning pin 25 is provided in the positioning hole 31 to be clamped with the outer wall of the material bin 5.

[0049] Specifically, during the production process, the bottom screen 27 is in a horizontal state, and the material is dried on the upper part of the bottom screen 27 of the material bin 5. After the drying process is completed, the material passes through the bottom pot 6 and enters the dry granulation component 7 for flipping out. The positioning pin 25 is pulled up, and the countersunk head of the positioning pin 25 will come out of the positioning hole 31. The handle 17 is rotated, and the handle 17 drives the rotating shaft 26 to rotate counterclockwise upward. The positioning pin 25 reaches another positioning hole 31, and the bottom screen 27 is at a 45-degree tilt angle, which can ensure that the material moves slowly downward under the action of gravity to prevent clogging of the dry granulation. After unloading for a period of time, continue to rotate the handle 17, and the positioning pin 25 reaches the remaining positioning holes 31. The bottom screen 27 is at a 90-degree tilt angle, which ensures that the material moves quickly downward under the action of gravity, completing the discharge of the material bin 5.

[0050] like Figure 6 As shown, in this embodiment, a hinged support is provided on the outer wall of the main body shell 12, and a hinged shaft is provided on the outer wall of the material bin 5. The hinged shaft is inserted into the hinged support from top to bottom and is rotatably connected thereto. When the material bin 5 rotates and does not interfere with the filter chamber, the material bin 5 is lifted upward to disengage the hinged shaft from the hinged support.

[0051] To meet the requirements of different experimental batches, the material bin 5 of various sizes can be replaced. During the replacement process, the right handle is gripped and the bin 5 is rotated to the left by a certain angle. When it does not interfere with the filter chamber 29, the bin 5 is pulled upward, causing the hinge shaft 23 to disengage from the hinge support 22. The hinge shaft 23 of the replacement bin 5 is then aligned with the hinge support 22 and guided into the hinge support 22 under the action of gravity. The right handle is gripped and the bin 5 is rotated to the right until it contacts the limit ring 20. The limit ring 20 limits the position of the bin 5, preventing it from rotating too far, and the bin 5 is replaced. Different batches of products can be produced on the same equipment, saving costs.

[0052] In addition, in order to ensure the positioning accuracy of the material bin 5, the filter chamber and the bottom pot 6, in this embodiment, the distance between the material bin 5 and the filter chamber is less than 5 mm, and the distance between the material bin 5 and the bottom pot 6 is less than 5 mm.

[0053] On the basis of the above embodiment, a position sensor is provided on the limiting ring 20 to detect whether the material bin 5 is rotated into position, so as to prevent the material bin 5 from not being in position.

[0054] It should be noted that a filter disc 35 and a filter bag 13 are provided inside the filter chamber. The filter disc 35 is used to prevent the material in the material bin 5 from entering the filter chamber. In addition, a first sealing ring 28 is provided between the filter disc 35 and the filter chamber, a second sealing ring 14 is provided between the filter chamber and the material bin 5, a third sealing ring 18 is provided between the material bin 5 and the bottom pot 6, and a fourth sealing ring 19 is provided between the bottom pot 6 and the dry granulation component 7.

[0055] Among them, the first sealing ring 28, the second sealing ring 14, the third sealing ring 18 and the fourth sealing ring 19 are all inflatable sealing rings. The four inflatable sealing rings fill all the gaps between the filter disc 35, the filter chamber 29, the material bin 5, the bottom pot 6 and the dry whole grain component 7 to achieve a sealing effect. In addition, the first sensor, the second sensor and the third sensor are respectively connected to the control system. The first sensor detects the inflation signal of the filter disc 35 and the filter chamber 29, the second sensor detects the inflation signal of the filter chamber 29 and the material bin 5, the material bin 5 and the bottom pot 6, and the third sensor detects the inflation signal of the bottom pot 6 and the dry whole grain component 7. The sensor feeds the signal back to the control system, and the control system transmits the inflation signal to the staff; when all the inflation states are detected, the next production process can be carried out; if any of the first sensor, the second sensor and the third sensor does not detect the corresponding inflation signal, the staff needs to check and re-inflate the corresponding gas; the setting of the first sensor, the second sensor and the third sensor can detect the inflation state of the corresponding position in real time, further ensuring that the entire production process of the product is in a closed environment.

[0056] In addition, the above-mentioned discharging component specifically includes a temporary storage barrel 10 and a lifting device 11 for adjusting the height of the temporary storage barrel 10. The temporary storage barrel 10 is adjusted to a suitable height by the lifting device 11, and the lifting device 11 is locked; it should be noted that after the discharge valve A8 installed at the lower end of the dry granulation component 7 is docked with the discharge valve B9 installed at the upper end of the temporary storage barrel 10, the discharge valve A8 and the discharge valve B9 are manually opened, and a communicating channel is formed inside the discharge valve B9 and the discharge valve A8. The material enters the temporary storage barrel 10 under the action of gravity, completing the discharging process.

[0057] In this embodiment, if Figure 6 As shown, a sampling tube 16 is provided on the material bin 5, and a connected sampling cavity is provided on the sampling tube 16, and the sampling cavity is located at the lower side of the sampling tube 16, with an opening downward, and a piston rod is slidingly provided in the sampling tube 16, and the sliding piston rod is used to control the conduction and closure of the sampling tube 16; specifically, by pulling the piston rod outward, the upper channel of the sampling cavity is opened, and under the action of gravity, the material flows into the sampling bottle 24 through the sampling cavity. After the sampling is completed, the piston rod moves back to seal the sampling cavity and block the sampling tube 16 at the same time to prevent the material in the material bin 5 from falling into the sampling bottle 24 or the ground at any time, so as to improve the sampling safety.

[0058] It should be noted that the sampling process adopts a bag-in-bag-out interface. The first sampling bag is put on the sampling bottle 24 and is clamped in the sampling cavity by the first O-ring. After the material flows into the sampling bottle 24, the second sampling bag is put on the outside of the first sampling bag. The second sampling bag is also clamped in the sampling cavity with the second O-ring. The first O-ring, the first PE sampling bag and the sampling bottle 24 inside it are pulled to the rear end of the second sampling bag. Two cable ties are used to separate the front and rear ends of the second sampling bag. The second sampling bag is cut open between the two cable ties. There is no dust leakage throughout the process, thereby achieving closed sampling.

[0059] In addition, a peristaltic pump 21 is provided on the main body housing 12. The slurry tube passes through the peristaltic pump 21 and is connected to the interface of the spray gun 30 through a quick-plug interface. The slurry flows through the slurry tube to the spray gun 30 through the extrusion action of the peristaltic pump 21, and is atomized by compressed air at the spray gun 30, enters the material bin 5, and is fully mixed with the material.

[0060] In this embodiment, if Figure 2 and Figure 3 As shown, the highly enclosed small-batch integrated pharmaceutical system also includes a cleaning system and a drainage system. The cleaning system is connected to an external water storage device through a cleaning water inlet 101. The cleaning system includes multiple cleaning diaphragm valves 102 and multiple cleaning guns 106. The multiple cleaning diaphragm valves 102 are used to control the cleaning of different areas. The multiple cleaning guns 106 are respectively installed on the filter chamber 29, the material bin 5, the bottom pot 6, and the dry granulation component 7 to clean the inside of the four. Figure 3As shown, a left filter chamber cleaning nozzle 104 and a right filter chamber cleaning nozzle 105 are provided on both sides of the filter chamber 29, and a cleaning gun 106 is provided on the bottom pot 6. Of course, the specific setting method can be set according to actual needs and is not specifically limited here.

[0061] The drainage system is located at the bottom of the discharge assembly and is connected thereto. In this embodiment, the drain pipe 109 is connected to the bottom of the temporary storage barrel 10 through the drain valve 108. The ends of the drain pipe 109 facing away from the drain valve 105 are respectively connected to the active drainage pipeline 111 and the sewage drainage pipeline 113, and the active drainage valve 110 and the sewage valve 112 are respectively provided on the active drainage pipeline 111 and the sewage drainage pipeline 113.

[0062] When the equipment needs to be cleaned, the cleaning water passes through the cleaning water inlet 101 and is cleaned on different areas through the cleaning diaphragm valve 102 respectively. The cleaning gun 106 on the material bin 5 can realize the cleaning of the material bin 5 body, and the cleaning gun 106 on the dry whole grain can realize the cleaning of the dry whole grain component 7; after the equipment is cleaned, when the cleaning water is discharged, it is necessary to open the drain valve 108 first, and the drain valve 108 is connected to the drain pipe 109. According to the nature of the discharged sewage, the active drain valve 110 or the sewage valve 112 is opened, and the sewage is discharged to the external inactivation device or the external ground drain accordingly to realize closed cleaning and drainage.

[0063] In addition, if Figure 4 As shown, an exhaust filter box 205 is arranged between the exhaust fan 206 and the filter chamber 29, and a primary filter 201 and a secondary filter 202 are arranged in the exhaust filter box 205. The primary filter 201 and the secondary filter 202 are respectively provided with an inspection door 203, and bag inlet and outlet interfaces are respectively provided on both sides of the two inspection doors 203.

[0064] The design of the exhaust filter box 205 can prevent dust from being discharged into the external environment and causing personal injury. When the exhaust filter box 205 is used for a long time, the primary filter 201 and the secondary filter 202 need to be cleaned or replaced. The cleaning or replacement process needs to be carried out in a closed environment. During the cleaning and replacement process, a PE bag is first put on the bag inlet and outlet interface, and the PE bag is fixed to the bag inlet and outlet interface with existing fasteners. The inspection door 203 is opened, and the primary filter 201 or the secondary filter 202 is taken out and sent to the corresponding location for cleaning. After cleaning, the primary filter 201 or the secondary filter 202 is put back into the exhaust filter box 205 in the same way, the inspection door 203 is closed, and the PE bag is removed.
