Background

The uniformity of the particle size of the granules is an important index for evaluating the quality of a medicinal product, and not only influences the appearance and medication compliance of the product, but also influences the quality stability of the product and the dissolution and release speed of the medicament, thereby influencing the bioavailability of the medicament. For this reason, the prepared granules need to be finished in production so as to separate and remove powder and large granules from the granules. The existing whole grain method is almost screened, however, the fine powder in the granules is difficult to completely remove by screening, and the granules generate a lot of new fine powder before entering a storage tank in the transportation process, thereby reducing the quality of the product packaged subsequently.

Detailed Description

The present invention will be described in detail with reference to the following examples.

As shown in fig. 1, the present invention comprises a storage tank body 1, wherein the top of the storage tank body 1 is provided with an inlet pipe 13, and the bottom is provided with a discharge pipe 14 with a valve. This is the basic structure of the existing storage tank, and the produced granules are put into the tank body through the feeding pipe 13 for storage, and then the discharging pipe 14 is opened to flow the granules into the automatic packing machine for internal packing.

However, before the particles enter the storage tank body 1, a considerable proportion of fine powder is generated due to collision and friction between materials and the pipe wall, and if the fine powder is not removed, the quality of the packaged product is affected, and therefore, the following improvement is performed on the basis of the existing storage tank body 1.

The device also comprises a vacuum tube 2 and a vacuum pump 3, wherein the open end of the vacuum tube 2 is arranged inside the storage tank body 1, the tail end of the vacuum tube is connected with the vacuum pump 3, the open end of the vacuum tube 2 is provided with a screen 4 (the aperture is 80 meshes) for filtering fine powder and particles, an induced duct 5 is also arranged in the storage tank body 1, and the open end of the induced duct 5 is opposite to the screen 4 and has a certain distance therebetween.

In the feeding process, the particles fall from the feeding pipe 13, the vacuum pump 3 is started to vacuumize the storage tank body 1 at the moment, when the particles pass through the opening end of the vacuum pipe 2, fine powder with relatively low density (the particle size is smaller than 80 meshes) is pumped away along the vacuum pipe 2 under the action of negative pressure, the particles with relatively high density continuously fall under the action of gravity, and the screen 4 plays a role in filtering the fine powder and prevents part of the particles with relatively high particle size (the particle size is larger than 80 meshes) from being pumped away. The air guide pipe 5 has the function of circulating air in the tank and increasing the air quantity near the screen 4, so that fine powder in particles can be blown into the vacuum pipe 2 more fully.

The tail end of the induced air pipe 5 is located outside the storage tank body 1 and is provided with an air volume adjusting valve 6, and the air volume adjusting valve 6 can correspondingly adjust the air volume in the induced air pipe 5 according to the size of negative pressure in the tank.

The open end of the vacuum tube 2 is located at the middle upper part of the storage tank body 1, as shown in fig. 2, in order to increase the area of the screen 4 and more efficiently extract the fine powder, the open end of the vacuum tube 2 is further provided with a funnel 7, and the screen 4 is arranged at the top end of the funnel 7.

As shown in fig. 3, in order to increase the blowing area of the induced duct 5, a nozzle 8 having an area approximately equal to that of the screen 4 is further disposed at the opening end of the induced duct 5, the top of the nozzle 8 is arc-shaped, and a plurality of air outlets 15 are disposed thereon.

The storage tank body 1 is provided with a vacuum gauge 9 for monitoring the pressure inside the tank body, thereby adjusting the output power of the vacuum pump 3.

The device also comprises a fine powder collecting tank 10, wherein the fine powder collecting tank 10 is positioned between the storage tank body 1 and the vacuum pump 3 and is communicated with the vacuum tube 2, and an air outlet of the fine powder collecting tank 10 is provided with a powder trapping bag 11. Specifically, the air inlet of the fine powder collecting tank 10 is located at the middle lower part, the air outlet and the powder collecting bag 11 are arranged at the top, wherein the powder collecting bag 11 is a cloth bag and can prevent fine powder from entering the vacuum pump 3 through the pipeline 2 to cause the blockage and damage of the vacuum pump 3, and the bottom of the fine powder collecting tank 10 is also provided with a discharge valve 12 for discharging the collected fine powder for recycling.
