[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figures 1 to 6 As shown, the embodiment of the utility model provides a high-efficiency reactor for pharmaceutical raw materials, including a reactor body 1, a driving motor 2, a stirring frame 3 and a reflux rotating mechanism 4;

[0035] The reactor body 1 has a containing chamber, which is used to contain pharmaceutical materials. The stirring frame 3 is arranged in the containing chamber, and the driving motor 2 is arranged on the top of the reactor body 1. The output shaft of the driving motor 2 is connected to the stirring frame 3 through the connecting shaft 21; the stirring frame 3 can play a role in mixing and stirring the materials in the reactor body 1. Specifically, the stirring frame 3 is connected to the driving motor 2 through the connecting shaft 21. When the driving motor 2 is started, it will drive the connecting shaft 21 to rotate, and then the stirring frame 3 will rotate in the containing chamber, so as to mix the materials evenly, ensure that the various raw materials of the materials can fully contact and react during the reaction process, and improve the reaction efficiency.

[0036] like Figure 1 and Figure 2As shown, the reflux rotating mechanism 4 includes a liquid pump 41, a first reflux pipe 42, a second reflux pipe 43, a flow splitting ring pipe 44 and a cyclone 45. The liquid pump 41 is mounted on the outside of the reactor body 1, the first reflux pipe 42 is passed through the bottom of the reactor body 1, and is connected to the liquid inlet end of the liquid pump 41; the cyclone 45 is arranged on the connecting shaft 21 above the stirring frame 3, the flow splitting ring pipe 44 is arranged above the cyclone 45, and is connected to the liquid outlet end of the liquid pump 41 through the second reflux pipe 43;

[0037] The liquid pump 41 is used to pump the material at the bottom of the accommodating chamber into the diverter annular pipe 44 through the first reflux pipe 42; the diverter annular pipe 44 is provided with a plurality of liquid outlet pipes 441 along the circumferential direction, and a plurality of vortex chambers 451 are provided at the top of the cyclone body 45 along the circumferential direction, and the liquid outlet of the liquid outlet pipe 441 faces the vortex chamber 451, and the liquid outlet pipe 441 is used to divert and spray the material in the second reflux pipe 43 into the vortex chamber 451; the material at the bottom of the reactor body 1 is difficult to be stirred by the stirring frame 3, which will cause sedimentation and uneven mixing of the raw materials. By pumping the material at the bottom to the top, convection and mixing efficiency can be promoted, and the mixing effect can be improved.

[0038] like Figure 4 and Figure 5 As shown, a conical umbrella 452 is provided at the bottom of the cyclone body 45, and a plurality of cyclone channels 453 are provided in the circumferential direction of the conical umbrella 452. A guide hole 454 is provided in the vortex chamber 451, and the guide hole 454 is used to guide the material into the cyclone channel 453. The cyclone channel 453 is used to apply centrifugal force to the material as the connecting shaft 21 rotates. The material at the bottom of the reactor body 1 is pumped into the diversion ring pipe 44 by the liquid pump 41, and then the material is diverted and sprayed into the vortex chamber 451 through the liquid outlet pipe 441. The conical umbrella 452 and the cyclone channel 453 at the bottom of the cyclone body 45 can form a cyclone effect on the material, thereby increasing the stirring and mixing efficiency of the material. In addition, the cyclone effect can make the material more evenly distributed in the reactor, avoiding the situation of excessively high or low local concentration, and ensuring the uniformity and stability of the reaction.

[0039] like Figure 1 and Figure 3 As shown, further, a heating tube 5 is included, and the heating tube 5 is arranged at the bottom of the reactor body 1, and the heating tube 5 is used to heat the material in the accommodating chamber. By heating the material through the heating tube 5, the material in the reactor can reach the required reaction temperature, promote the reaction rate, and accelerate the reaction process.

[0040] like Figure 1 and Figure 6As shown, further, an ultrasonic vibration plate assembly 6 is included. An embedding groove is provided on the side wall of the reactor body 1. The ultrasonic vibration plate assembly 6 is arranged in the embedding groove. The ultrasonic vibration plate assembly 6 is used to generate high-frequency vibration for the material in the accommodating chamber. Ultrasonic vibration can generate tiny bubbles and micro-flows in the material, thereby increasing the disturbance and mixing efficiency inside the material, so as to fully mix the raw materials of different components and promote the contact and reaction rate between the reaction substances.

[0041] like Figure 4 and Figure 5 As shown, further, the swirl channel 453 is gradually expanded from the inside to the outside. Such a configuration can reduce the flow resistance of the liquid in the channel, reduce the pressure loss of the liquid when flowing through the channel, increase the flow speed of the liquid in the channel, and improve the mixing efficiency and mass transfer rate.

[0042] like Figure 1 and Figure 3 As shown, further, a liquid conduit 11 is provided at the bottom of the reactor body 1, and an electric valve 12 is provided on the liquid conduit 11, and the electric valve 12 is used to control the conduction or cutoff of the liquid conduit 11. Through the electric valve 12, the operator can control the conduction or cutoff of the liquid conduit 11 at the bottom of the reactor body 1, thereby controlling the discharge of materials.

[0043] Furthermore, a temperature sensor (not shown) is included, which is arranged on the inner wall of the reactor body 1, and is electrically connected to the heating tube 5, and is used to detect the temperature of the material in the accommodating chamber. The temperature sensor can monitor the temperature of the reaction material in real time, and adjust the heating power of the heating tube 5 according to the actual situation, so as to accurately control the temperature inside the reactor body 1 and ensure that the reaction is carried out within a suitable temperature range.

[0044] like Figure 1 As shown, further, a liquid inlet pipe 13 is provided on the top of the reactor body 1, and the liquid inlet pipe 13 is used to introduce materials into the accommodating chamber. The setting of the liquid inlet pipe 13 can facilitate the real-time addition of supplementary raw materials to the reactor body 1 during the mixing reaction process.

[0045] like Figure 1 As shown, further, a support frame 14 is included, and the support frame 14 is connected to the reactor body 1 to support the reactor body 1. The setting of the support frame 14 can improve the support stability of the reactor body 1 and prevent the heating pipe 5 from contacting the ground.

[0046] The reactor body 1 of the utility model contains materials for pharmaceutical preparation, the stirring frame 3 can mix and stir the materials, the liquid pump 41 can pump the materials at the bottom of the reactor body 1 into the diversion ring pipe 44, and then the materials are diverted and sprayed into the vortex chamber 451 through the liquid outlet pipe 441. The conical umbrella 452 and the vortex channel 453 at the bottom of the vortex body 45 can form a vortex effect, thereby increasing the stirring and mixing efficiency of the materials, and the vortex effect can make the materials more evenly distributed in the reactor, avoid the situation where the local concentration is too high or too low, and ensure the uniformity and stability of the reaction; the material at the bottom is pumped to the top by the liquid pump 41, which can promote the convection and mixing efficiency of the materials and improve the mixing effect.
