Description

Technical Field

[0001] This utility model relates to the field of suspending agents, and in particular to a raw material mixing device for suspending agent production. Background Technology

[0002] Suspension agents are typically formulations in which solid active pharmaceutical ingredients are dispersed in water. During the production and processing of suspension agents, mixing devices are required to mix the solid raw materials and the liquid drug. Most existing suspension feedstock mixing devices do not have a solid feedstock pretreatment structure. Due to the varying particle sizes of the solid feedstock, larger particles tend to settle rapidly under gravity during subsequent mixing, while smaller particles are easily over-crushed, resulting in ultrafine particles. This leads to significant differences in particle velocity within the system, accelerating stratification and affecting the stability of the subsequent suspension. Therefore, we propose a mixing device with a solid feedstock pretreatment structure to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to solve the following problems existing in the prior art: due to the different particle sizes of the solid raw materials of the suspending agent, in the subsequent mixing process, the larger particles are prone to rapid sedimentation due to gravity, while the smaller particles are prone to excessive crushing, resulting in ultrafine particles. This leads to significant differences in the movement speed of particles in the system, accelerates stratification, and affects the stability of the subsequent suspending agent.

[0004] To address the problems existing in the prior art, this utility model provides a raw material mixing device for suspending agent production, including a mixing tank, an airflow tank mounted on one side of the mixing tank via a mounting base, a conveying pipe at the input end of the airflow tank, a filter at the output end above the airflow tank, a guide pipe at the output end of the filter, a feed pipe above the mixing tank, and a material collection assembly on the feed pipe.

[0005] Furthermore, the material collection assembly includes a material collection tank and a connecting pipe. The material collection tank is fixed above the feed pipe, and the output end below the material collection tank is connected to the feed pipe through the connecting pipe and an electrically controlled valve.

[0006] Furthermore, the input end above the collection tank is connected to the guide pipe via a connecting pipe.

[0007] Furthermore, the collection tank is also equipped with a weighing component, which can be used to detect the weight of the material in the collection tank during use.

[0008] Furthermore, multiple high-pressure airflow nozzles are provided below the airflow tank, and the high-pressure airflow nozzles are connected to an external compressed air pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a high-speed airflow in conjunction with an airflow tank to crush solid raw materials for suspension. The crushed material enters a filter along with the airflow. Materials that meet the filtration criteria are discharged through a feed pipe, while those that do not meet the filtration criteria are returned to the airflow tank for further crushing. This process achieves the purpose of pre-treatment of solid raw materials, ensuring uniform particle size and facilitating uniform decomposition during subsequent mixing to guarantee the stability of the suspension. Finally, all pre-treated solid raw materials are guided through a feed pipe to a collection tank for temporary storage, facilitating centralized management by staff, ensuring uniformity of feed, and preventing uneven or over-mixing due to inconsistent mixing times. This enhances the practicality of the device. Attached Figure Description

[0012] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0013] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0014] Example 1 like Figure 1-3 As shown, a raw material mixing device for suspension production includes a mixing tank 1. An airflow tank 7 is provided on one side of the mixing tank 1 via a mounting base 8. A conveying pipe 6 is provided at the input end of the airflow tank 7. A filter 5 is provided at the output end above the airflow tank 7. A guide pipe 3 is provided at the output end of the filter 5. A feed pipe 4 is provided above the mixing tank 1. A material collection assembly is provided on the feed pipe 4. In this embodiment, the material collection assembly includes a material collection tank 2 and a connecting pipe. The material collection tank 2 is fixed above the feed pipe 4. The output end of the material collection tank 2 is connected to the feed pipe 4 through the connecting pipe and the electric control valve 9. The input end of the material collection tank 2 is connected to the guide pipe 3 through the connecting pipe. The material collection tank 2 is also equipped with a weighing component. In use, the weight of the material in the material collection tank 2 can be detected by the weighing component. The airflow tank 7 is equipped with multiple high-pressure airflow nozzles below it. The high-pressure airflow nozzles are connected to an external compressed air pipe.

[0015] Working principle description: The solid raw material of the suspension is introduced into the airflow tank 7 through the conveying pipe 6. The high-speed airflow from the high-pressure airflow nozzle at the bottom of the airflow tank 7 drives the material to move at high speed inside the airflow tank 7, causing the material to collide, rub, and be crushed. The crushed material enters the filter 5 with the airflow. The material that meets the filtration conditions is discharged by the feed pipe 3, while the material that does not meet the filtration conditions is returned to the airflow tank 7 for crushing. This achieves the purpose of pretreatment of the solid raw material, keeping the particle size of the solid raw material of the suspension uniform, which is convenient for uniform decomposition during subsequent mixing and ensures the stability of the suspension. Finally, all the pretreated solid raw materials are introduced into the collection tank 2 through the feed pipe 3 for temporary storage, which is convenient for the staff to manage. Afterwards, the staff can open the electric control valve 9 to introduce the material in the collection tank 2 into the mixing tank 1 through the feed pipe 4 for mixing, ensuring the uniformity of the feed and avoiding uneven mixing or over-mixing due to inconsistent mixing time, thus increasing the practicality of the device.
