Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, specifically to a moisture-proof dispensing nozzle for tablets and powders. Background Technology

[0002] The processing of tablets involves multiple steps, including drying, tableting, reaction, and mixing.

[0003] During drug mixing, heating processes are involved, such as in reaction vessels and heated agitators. During the feeding process, steam rises from the heated agitator and condenses into water droplets upon encountering the nozzle. When the powder is fed through the nozzle, it combines with the water droplets, causing the powder to clump together and block the nozzle, resulting in poor powder feeding. Furthermore, during the feeding process, the powder agglomerates due to electrostatic effects and interparticle interactions (such as van der Waals forces), which is detrimental to mixing. To address this issue, we propose a moisture-proof tablet powder feeding nozzle. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof tablet powder dispensing nozzle to solve the problems mentioned in the background art, such as steam rising from the heated agitator during the dispensing process, condensing into water droplets upon encountering the nozzle, causing powder to combine with water droplets and clump together, thus clogging the nozzle and hindering the smooth dispensing of powder. Furthermore, during the dispensing process, the powder agglomerates due to electrostatic effects and interparticle interactions, hindering mixing. To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof tablet powder dispensing nozzle, including a discharge pipe;

[0005] A moisture-proof component, comprising a fixing ring, a flow guide fixedly connected to the bottom edge of the fixing ring, an air inlet pipe fixedly connected to the top of the fixing ring, an anti-slip ring fixedly sleeved on the side surface of the air inlet pipe, and a connecting pipe sleeved on the side surface of the anti-slip ring.

A rotating shaft is fixedly connected to the end of the output shaft of the drive motor. Screw blades are fixedly connected to the side surface of the rotating shaft.

[0008] More preferably, the inner ring surface of the fixing ring is fixedly sleeved on the side surface of the discharge pipe, and the air inlet pipe communicates with the cavity formed between the guide shroud and the discharge pipe.

[0009] More preferably, the air deflector is inverted conical in shape, and the plurality of anti-slip rings are arranged in a linear array along the longitudinal direction of the air intake pipe.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a moisture-proof tablet / powder dispensing nozzle, including a dispensing pipe 1;

[0028] Moisture-proof component 2 includes a fixing ring 201, a guide hood 202 is fixedly connected to the bottom edge of the fixing ring 201, an air inlet pipe 203 is fixedly connected to the top of the fixing ring 201, an anti-slip ring 204 is fixedly sleeved on the side surface of the air inlet pipe 203, and a connecting pipe 205 is sleeved on the side surface of the anti-slip ring 204.

[0029] Airflow assembly 3 includes a flow splitting interface 301. One end of the flow splitting interface 301 is fixedly connected to a flow splitter 302. The other side of the flow splitter 302 is fixedly connected to a connecting pipe 304. The other end of the connecting pipe 304 is fixedly connected to an air pump 303.

[0030] The feeding assembly 4 includes a movable slot 404 and a drive motor 403. The output shaft of the drive motor 403 is movably connected through the movable slot 404. A rotating shaft 401 is fixedly connected to the end of the output shaft of the drive motor 403. A screw conveyor blade 402 is fixedly connected to the side surface of the rotating shaft 401.

[0031] In this embodiment, as Figure 2 , Figure 5 and Figure 6As shown, the inner ring of the fixing ring 201 is fixedly sleeved on the side surface of the discharge pipe 1. The air inlet pipe 203 communicates with the cavity formed between the guide shroud 202 and the discharge pipe 1. During use, the drug powder enters the feed pipe 5 and the discharge pipe 1 through the storage box. Then, the drive motor 403 and the air pump 303 are started, causing the auger blades 402 to push the material out from the bottom of the discharge pipe 1. The air pump 303 delivers gas to the cavity between the discharge pipe 1 and the guide shroud 202 through the distributor 302 and the connecting pipe 205. The airflow in this cavity is ejected through the bottom of the guide shroud 202, while the material is discharged through the bottom of the discharge pipe 1 at the same time. At this time, the airflow discharged from the cavity blows downward, and because the guide shroud 202 is inverted conical, it forms an airflow barrier, making the reaction vessel... The steam in the mixing container cannot directly contact the discharge port at the bottom of the discharge pipe 1, thus preventing water droplets from condensing at the bottom of the discharge pipe 1. The inclined air inlet pipe 203 allows the powder material to disperse quickly under the action of gas turbulence after discharge, preventing powder agglomeration. Through the moisture-proof component 2 and the airflow component 3, the end of the discharge pipe 1 forms an airflow barrier through the flow guide 202 during discharge, thus preventing water vapor from condensing at the bottom of the discharge pipe 1. This prevents the material in the discharge pipe 1 from clumping due to water vapor mixing. The airflow is sprayed downward through the flow guide 202, causing turbulence at the bottom of the flow guide 202, which disperses the powder material under the action of turbulence, preventing powder agglomeration after discharge, thereby accelerating the mixing efficiency.

[0032] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, the air deflector 202 is inverted cone shape, and multiple anti-slip rings 204 are arranged in a linear array along the longitudinal direction of the air intake pipe 203.

[0033] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, multiple air inlet pipes 203 are arranged in a circular array around the central axis of the discharge pipe 1. The air inlet pipes 203 are inclined, and the connecting pipe 205 is a flexible hose.

[0034] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, the other end of the connecting pipe 205 is fixedly connected to the diversion interface 301, and the other end of the diversion interface 301 is connected to the diverter 302.

[0035] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, one end of the connecting pipe 304 is connected to the distributor 302, and the other end of the connecting pipe 304 is connected to the output end of the air pump 303.

[0036] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, the bottom of the drive motor 403 is fixedly connected to the top of the discharge pipe 1, and the outer edge of the auger blade 402 fits into the inner wall of the discharge pipe 1.

[0037] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, a feed pipe 5 is fixedly connected to the side surface of the discharge pipe 1, and the inside of the feed pipe 5 is connected to the inside of the discharge pipe 1.

[0038] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, the other end of the feed pipe 5 is connected to the storage box, and the feed pipe 5 is inclined.

[0039] The method of use and advantages of this utility model: The working process of this moisture-proof tablet / powder dispensing nozzle is as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during use, the drug powder enters the feed pipe 5 and the discharge pipe 1 through the storage tank. Then, the drive motor 403 and the air pump 303 are started, causing the auger blades 402 to push the material out from the bottom of the discharge pipe 1. The air pump 303 delivers gas to the cavity between the discharge pipe 1 and the guide shroud 202 through the distributor 302 and the connecting pipe 205. The airflow in this cavity is ejected through the bottom of the guide shroud 202, and the material is discharged through the bottom of the discharge pipe 1 at the same time. At this time, the airflow discharged from the cavity blows downward, and because the guide shroud 202 is inverted conical, it forms an airflow barrier, preventing the steam in the reactor or stirring container from directly contacting the discharge port at the bottom of the discharge pipe 1, thereby avoiding the condensation of water droplets at the bottom of the discharge pipe 1. Furthermore, the inclined air inlet pipe 203 causes the powder to disperse quickly under the action of gas turbulence after discharge, preventing the powder from clumping together.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
