Description

Technical Field

[0001] The utility model relates to the field of medicines, in particular to a high-speed mixing granulator. Background Art

[0002] In the process of modern pharmaceutical manufacturing, some traditional Chinese medicines are usually ground into powder using a grinding device in order to make it easier for doctors to quantify the dosage when dispensing medicines. The powder is then made into uniform granular medicines using a high-speed mixing granulator and loaded into capsules for quantification. This operation not only facilitates the portability of medicines for patients, but also ensures the stability and consistency of the medicines.

[0003] The existing high-speed mixing granulator usually first evacuates the vacuum granulation tank, and sucks the raw materials into the tank from the feed port of the vacuum cover through the negative pressure in the pipe. While ensuring the vacuum inside the vacuum granulation tank, the raw materials are stirred and granulated (after stirring evenly, the adhesive switch connected to the adhesive nozzle is turned on), and the raw materials in the tank are wet mixed and cut.

[0004] The existing high-speed mixing granulator can efficiently granulate the raw material powder under vacuum state, but when the raw material is sucked at the feed port, the vacuum level in the tank will be reduced. In order to ensure the vacuum level in the tank, it is necessary to continuously evacuate the tank. During the evacuation, the raw material powder will be sucked into the vacuum device. In the long run, the life of the vacuum device will inevitably be affected and the vacuum speed of the vacuum device will be reduced. Utility Model Content

[0007] As an improvement, the cloth bag anti-blocking device includes an anti-blocking cloth bag located on a cloth bag support frame, sleeved on the outer wall of the cloth bag support frame, and a fixed sleeve for fixing the anti-blocking cloth bag.

[0008] As an improvement, a stirring device is provided on the bottom of the vacuum granulation tank, and a cutting knife device is provided on the side of the vacuum granulation tank. Both the stirring device and the cutting knife device are driven by a rotating motor, and the output shaft of the rotating motor passes through the bottom and side wall of the vacuum granulation tank.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] As the instruction manual Figure 1 , 2 As shown in , 4 and 5, it comprises a vacuum granulation tank 1, the bottom surface of the vacuum granulation tank 1 is provided with a workbench 2, the tank mouth of the vacuum granulation tank 1 is provided with a vacuum cover 3, the interior of the vacuum cover 3 is provided with a feed port 31, a vacuum port 32 and an adhesive nozzle 33, one side of the feed port 31 is provided with a stop valve 311 for controlling the inflow and outflow of raw materials, the vacuum cover 3 is connected to the tank mouth of the vacuum granulation tank 1 through a bolt structure, the feed pipe is connected to the other end of the stop valve 311, and the adhesive nozzle 33 is connected to the adhesive storage tank through an adhesive pipe on the outer wall, a vacuum device 4 is provided on one side of the vacuum port 32, the vacuum device 4 is connected to the workbench 2 through a bolt structure, the vacuum device 4 is connected to the power supply device through a wire, the vacuum device 4 is used to convert the inside of the vacuum granulation tank 1 into a vacuum state, the feed port 31 is controlled by the stop valve 311, and the raw materials can be sucked into the vacuum granulation tank 1 according to the demand for quantitative processing.

[0023] The bottom surface of the vacuum granulation tank 1 is provided with a stirring device 11, and the side surface of the vacuum granulation tank 1 is provided with a cutting knife device 12. The stirring device 11 and the cutting knife device 12 are both driven by a rotating motor 13, and the rotating motor 13 is connected to the power supply device through a wire. The output shaft of the rotating motor 13 passes through the bottom surface and side wall of the vacuum granulation tank 1, and the output shaft of the rotating motor 13 connected to the stirring device 11 passes through the bottom surface of the workbench 2. The rotating motor 13 and the vacuum pumping device 4 are both connected to the workbench 2 through a bolt structure. The output shaft of the rotating motor 13 is connected to the through holes on the bottom and side surfaces of the vacuum granulation tank 1 through a sealed bearing 9. 12 are connected to the output shaft of the rotating motor 13 through a connecting key. The top of the stirring device 11 is provided with a stirring fixing screw 111 for fixing the output shaft of the rotating motor 13. The stirring fixing screw 111 is connected to the internal through hole of the output shaft of the rotating motor 13 through a thread. The raw material rotates along the arc in the tank through the extrusion and thrust of the stirring device 11, and as the rotation speed increases, the raw material moves upward. After moving to the side of the tank mouth, it falls back to the bottom of the tank due to gravity, so that the raw materials in the tank can be evenly mixed. After the raw materials are mixed, the adhesive sprayed from the adhesive nozzle 33 blocks the raw materials; then it is broken into uniform drug particles by the cutting knife device 12.

[0024] A T-shaped discharge port 14 is provided on the side of the vacuum granulation tank 1, and the T-shaped discharge port 14 is opposite to the cutting knife device 12. A sealing telescopic rod 15 for sealing the T-shaped discharge port 14 is provided at the horizontal end of the T-shaped discharge port 14. The output shaft of the sealing telescopic rod 15 is connected to the inner wall of the T-shaped discharge port 14 through body contact, and the sealing telescopic rod 15 is connected to the outlet end of the T-shaped discharge port 14 through a bolt structure. The sealing telescopic rod 15 is connected to the power supply device through a wire. Under normal circumstances, the T-shaped discharge port 14 is sealed by the sealing telescopic rod 15 to avoid a decrease in the vacuum degree in the tank. After the granulation is completed, the sealing telescopic rod 15 is retracted, so that the finished product is thrown out of the vacuum granulation tank 1 under the action of the centrifugal force of the stirring device 11, so that it flows out through the discharge port at the side end of the T-shaped discharge port 14.

[0025] As the instruction manual Figure 1 , 2As shown in Figure 3, a three-way joint 5 is provided between the outer end of the vacuum port 32 and the vacuum pumping device 4. The vacuum pumping device 4 is connected to one side of the three-way joint 5 through a vacuum pipe. A cloth bag anti-blocking device 6 is provided at the inner wall end of the vacuum port 32. An ultrasonic dust removal device 7 for cleaning the cloth bag anti-blocking device 6 is provided at the other end of the three-way joint 5. The cloth bag anti-blocking device 6 and the ultrasonic dust removal device 7 are opposite to each other. The cloth bag anti-blocking device 6 includes an anti-blocking cloth bag 62 located on a cloth bag support frame 61 and sleeved on the outer wall of the cloth bag support frame 61, and a fixed shaft sleeve 63 for fixing the anti-blocking cloth bag 62. The anti-blocking cloth bag 62 passes through the inner wall of the fixed shaft sleeve 63. The inner wall of the vacuum port 32 and the inner hole of the fixed shaft sleeve 63 They are all connected to the outer wall of the bag support frame 61 through threads, and the external connection ports of the ultrasonic dust removal device 7 and the vacuum port 32 are connected to the three-way joint 5 through the sealing gasket 8. After the vacuum device 4 is started, the anti-blocking bag 62 will filter the raw material powder so that no dust will appear in the extracted air, ensuring that the inside of the vacuum device 4 will not inhale powder; in order to ensure that the outer surface of the anti-blocking bag 62 will not affect the air inhalation due to the accumulation of dust, the ultrasonic dust removal device 7 is used to perform regular vibration dust removal on the anti-blocking bag 62 to avoid congestion of the pores on the surface of the anti-blocking bag 62, and because the bag anti-blocking device 6 and the ultrasonic dust removal device 7 are opposite to each other, the efficiency of the ultrasonic dust removal device 7 can be maximized.

[0026] During the specific implementation of the utility model, the vacuum device 4 is started to vacuum the vacuum granulation tank 1. During the vacuuming process, the feed pipe connected to the raw material is inserted into the raw material, the stop valve 311 is opened, and the raw material powder is sucked into the tank by the negative pressure in the tank. After the suction is completed, the stop valve 311 is closed. When the vacuum degree in the tank reaches the standard, the vacuum device 4 is closed; the rotating motor 13 of the stirring device 11 is turned on, and the speed of the stirring device 11 is slowly increased so that the raw material can be evenly stirred without damaging the stirring blades of the stirring device 11; after the mixing is evenly carried out, the adhesive nozzle 33 is started. , the raw material is gradually moistened by atomizing the adhesive and turned into a soft material; the rotating motor 13 of the cutting knife device 12 is started, and the stirring device 11 and the cutting knife device 12 which are perpendicular to each other will generate eddy currents during the rotating motion, and the raw material is further fully tumbled, collided and sheared in the three-dimensional motion, so that the collision of the raw material particles is more uniform and delicate, and finally uniform and stable spherical particles are formed; after the granulation operation is completed, the sealing telescopic rod 15 is retracted, so that the finished particles are thrown into the T-shaped discharge port 14 with the centrifugal force of the stirring device 11, and under the action of gravity, they flow out from the open flow on the side of the T-shaped discharge port 14.

[0027] During the vacuum operation, the raw material powder will be isolated by the anti-blocking bag 62, and the air can be drawn out from the pores of the anti-blocking bag 62. Because the anti-blocking bag 62 is mounted on the bag support frame 61, it is ensured that the anti-blocking bag 62 will not be deformed by the suction force of the vacuum device 4. When the efficiency of the vacuum device 4 is reduced (the powder on the surface of the anti-blocking bag 62 is too thick), the ultrasonic dust removal device 7 is started to remove the dust from the anti-blocking bag 62. The powder on the surface of the anti-blocking bag 62 is the same as the raw material, and no waste of raw materials is caused.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
