Technical Field

[0002] Pharmaceutical intermediates are some chemical raw materials or chemical products used in the process of drug synthesis. Most pharmaceutical intermediates are in powder form. In pharmaceutical synthesis, pharmaceutical intermediates need to be added to the synthesis bin through a feeding device for processing. However, under the existing technical conditions, there are many problems in adding pharmaceutical intermediates. Most pharmaceutical intermediates are in powder form and are easily lumpy under pressure.

[0026] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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.

[0027] As attached Figure 1-6 The pharmaceutical intermediate feeding device for drug synthesis shown includes a dispersion cylinder 1, a screening cylinder 2 is arranged at the bottom of the dispersion cylinder 1, a conveying cylinder 3 is arranged at the bottom of the screening cylinder 2, a feed port 4 is arranged at the top of the dispersion cylinder 1, and a plurality of discharge ports 5 are arranged at the bottom, and a discharge hopper 7 is arranged at the bottom of the discharge cylinder 6.

[0028] Specifically, when feeding the pharmaceutical intermediates for drug synthesis, the operator pours the materials into the dispersion cylinder 1 through the feed port 4, and the agglomerated materials in the dispersion cylinder 1 are squeezed and crushed through the dispersion structure inside the dispersion cylinder 1. At the same time, the materials are discharged through multiple discharge ports 5. The materials discharged through the multiple discharge ports 5 can be evenly dispersed and transported to the inside of the screening cylinder 2. After the vibration screening structure inside the screening cylinder 2 is vibrated and processed, the agglomerated materials can be further broken up and enter the inside of the conveying cylinder 3. After being evenly transported through the feeding structure inside the conveying cylinder 3, they enter the inside of the discharge cylinder 6. After being quantitatively weighed by the quantitative weighing structure, they are discharged to the inside of the drug synthesis equipment through the discharge hopper 7, thereby completing the feeding operation of the pharmaceutical intermediates.

[0029] Combined with Figure 1 , 5 As shown, a quantitative weighing structure is provided inside the discharge barrel 6, and the quantitative weighing structure includes a quantitative barrel 8, which is installed inside the discharge barrel 6, and a weighing plate 9 is provided at the bottom of the inner cavity of the quantitative barrel 8, and two weighing sensors 10 are provided at the bottom of the weighing plate 9. A rotating motor 11 is provided on the surface of the discharge barrel 6, and the output end of the rotating motor 11 extends to the inside of the discharge barrel 6 and is connected to the quantitative barrel 8. The quantitative barrel 8 is rotatably connected inside the discharge barrel 6 through an axle pin.

[0030] A discharge pipe 27 is provided at the bottom of the conveying cylinder 3 , and the discharge pipe 27 is located directly above the metering cylinder 8 .

[0031] Specifically, in this structure, the material can be quantitatively weighed before the loading operation is performed. Specifically, when the conveyed material is discharged through the discharge pipe 27 at the conveying cylinder 3, it falls onto the surface of the weighing plate 9 inside the quantitative cylinder 8, and is weighed using the weighing sensor 10 of model QS-5t at the bottom of the weighing plate 9. When a certain weight is reached, the external controller controls the rotation motor 11 to rotate the quantitative cylinder 8 inside the discharge cylinder 6, so that the weighed material is poured out and discharged through the discharge hopper 7.

[0032] It is worth noting that in this structure, the weighing sensor 10 is an existing sensor on the market, and its specific working principle and connection method are all existing technologies, which will not be elaborated in detail in this utility model.

[0033] In this embodiment, as shown in the attached Figure 1 , 2As shown, the interior of the dispersion cylinder 1 is provided with a dispersion structure for crushing and dispersing the material, and the dispersion structure specifically includes an extrusion plate 12, which is movably installed inside the dispersion cylinder 1, and a driving motor 13 is provided at one end of the dispersion cylinder 1, and a screw rod 14 is provided at the output end of the driving motor 13, and a guide rod 15 is provided at the top of the screw rod 14, and the screw rod 14 at the output end of the driving motor 13 is coaxially connected, the extrusion plate 12 is threadedly connected to the outside of the screw rod 14, and the extrusion plate 12 is slidably connected to the guide rod 15, and the outer wall of the extrusion plate 12 is attached to the inner wall of the dispersion cylinder 1.

[0034] Specifically, in this structure, the agglomerated material can be crushed and the material can be uniformly introduced into the interior of the screening cylinder 2. Specifically, after the material enters the interior of the dispersion cylinder 1 through the feed port 4, the driving motor 13 drives the screw 14 inside the dispersion cylinder 1 to rotate, so that the extrusion plate 12 moves under the guidance of the guide rod 15. The movement of the extrusion plate 12 can extrude and crush the agglomerated material, and the material can be discharged from multiple discharge ports 5. Multiple materials discharged from the discharge ports 5 can uniformly enter the interior of the screening cylinder 2 for further screening and vibration treatment.

[0035] In this embodiment, as shown in the attached Figure 1 , 3 As shown in Figure 6, a vibration screening structure is provided inside the screening cylinder 2, and the vibration screening structure includes a vibration frame 16, which is fixedly installed on the inner wall of the screening cylinder 2, and a slide bar 17 and a screening net 18 are installed inside the vibration frame 16. The screening net 18 is slidably connected to the outside of the slide bar 17, and springs 19 are provided on the top and bottom of the screening net 18 outside the slide bar 17. The vibration screening structure also includes a servo motor 20, which is installed on the surface of the screening cylinder 2, and a connecting rod 21 is provided inside the screening cylinder 2 at the bottom of the vibration frame 16, and a dialing plate 22 is provided outside the connecting rod 21 just below the vibration frame 16, and a striking ball 23 is provided at one end of the dialing plate 22. The output end of the servo motor 20 is coaxially connected with the connecting rod 21 inside the screening cylinder 2.

[0036] Specifically, after the preliminary crushed materials evenly enter the interior of the screening cylinder 2, they are evenly distributed on the screening net 18 to prevent the materials from piling up on the screening net 18. The screening net 18 can screen and process the crushed materials and discharge them, while the incompletely crushed materials stay on the screening net 18. At this time, the servo motor 20 drives the connecting rod 21 to rotate inside the screening cylinder 2, and drives the dial plate 22 and the striking ball 23 to repeatedly strike the vibration frame 16, so that the outer edge of the screening net 18 slides up and down outside the sliding rod 17 at the vibration frame 16, so that the spring 19 is continuously squeezed and reset, so that the screening net 18 shakes up and down, and then the materials on the screening net 18 are further crushed, so that the materials are discharged from the screening net 18.

[0037] In this embodiment, as shown in the attached Figure 1 , 4 As shown, a material conveying structure is arranged inside the conveying cylinder 3, and the material conveying structure specifically includes a conveying motor 24, and the conveying motor 24 is installed at one end of the conveying cylinder 3, a conveying rod 25 is arranged inside the conveying cylinder 3, and a plurality of conveying dragons 26 are arranged outside the conveying rod 25, and the output end of the conveying motor 24 is coaxially connected with the conveying rod 25 inside the conveying cylinder 3.

[0038] Specifically, when the crushed material passes through the screening drum 2 and enters the interior of the conveying drum 3, the conveying motor 24 drives the conveying rod 25 to operate and drives the conveying dragon 26 to rotate, so that the material is evenly conveyed and enters the interior of the discharge drum 6 through the discharge pipe 27 for quantitative processing.

[0039] When the above structure is used, the operator firstly allows the pharmaceutical intermediate to enter the dispersion cylinder 1 through the feed port 4, and then the drive motor 13 drives the screw 14 inside the dispersion cylinder 1 to rotate, so that the extrusion plate 12 moves under the guidance of the guide rod 15. The movement of the extrusion plate 12 can extrude and crush the agglomerated materials, and the materials are discharged from the multiple discharge ports 5.

[0040] A plurality of materials discharged from the discharge port 5 can evenly enter the internal screening net 18 of the screening drum 2. The screening net 18 can screen and discharge the crushed materials, while the incompletely crushed materials stay on the screening net 18. At this time, the servo motor 20 drives the connecting rod 21 to rotate inside the screening drum 2, and drives the dial plate 22 and the striking ball 23 to repeatedly strike the vibration frame 16, so that the outer edge of the screening net 18 slides up and down outside the sliding rod 17 at the vibration frame 16, so that the spring 19 is continuously squeezed and reset, so that the screening net 18 shakes up and down, and then the materials on the screening net 18 are further crushed, so that the materials are discharged from the screening net 18 and enter the interior of the conveying drum 3;

[0041] The conveying motor 24 is used to drive the conveying rod 25 to operate, and drives the conveying dragon 26 to rotate, so that the material is evenly conveyed and enters the inside of the discharge cylinder 6 through the discharge pipe 27;

[0042] Finally, when the conveyed material is discharged through the discharge pipe 27 at the conveying cylinder 3, it falls onto the surface of the weighing plate 9 inside the metering cylinder 8 and is weighed using the weighing sensor 10 at the bottom of the weighing plate 9. When it reaches a certain weight, an external controller is used to control the rotation of the rotating motor 11 to rotate the metering cylinder 8 inside the discharge cylinder 6, so that the weighed material is poured out and discharged through the discharge hopper 7.
