Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical preparation technology, and in particular to an apparatus for preparing granules. Background Technology
[0002] Traditional granule formulations have several problems in current granule preparation processes. During granulation, granules produced by ordinary squeezing and extrusion have relatively low strength. This is because the fusion adhesion between the fine powder particles is weak, resulting in insufficient structural strength of the granules. Such granules are prone to breakage during subsequent storage, transportation, and pipeline transport. For example, during stacking and storage, the granules are easily broken by gravity; during transportation, collisions between granules and friction with transport vehicles cause a large number of granules to break into fine powder; during pipeline transport, friction between the granules and the inner wall of the pipe also damages the granules.
[0003] The presence of excessive fine powder has a serious impact on product quality and production. On the one hand, it leads to large deviations in packaging measurement, making it difficult to ensure the accurate content of the active ingredient in each bag of granules, thus affecting the stability of the product's efficacy. On the other hand, fine powder easily adheres to packaging materials, reducing the strength of the packaging mold, making the packaging not airtight, affecting the product's appearance, and may also cause the medicine to become damp and deteriorate, shortening its shelf life. If the amount of fine powder exceeds the key requirements, the product is considered unqualified, which undoubtedly increases production costs, reduces production efficiency, and negatively impacts the company's economic benefits and market competitiveness. Utility Model Content
[0004] This invention provides an apparatus for preparing granules, which can improve the yield of granules.
[0005] This utility model provides a granule preparation apparatus, including a granulation unit and a granulation collection unit;
[0006] The granulation unit includes multiple feeding plates installed in the granulation chamber. The multiple feeding plates and the inner wall of the granulation chamber form a feeding channel. A swing roller is installed at the bottom of the feeding channel. The swing roller is driven to rotate by a motor. The swing roller includes a connecting plate and extrusion columns. The multiple extrusion columns are fixedly connected to the connecting plate circumferentially. The connecting plate is fixedly connected to the rotating shaft of the motor. The bottom of the swing roller is covered with a screen.
[0007] The pellet collecting unit is funnel-shaped with an open top and is installed below the pelletizing unit to receive the pellets produced by the oscillating roller in the pelletizing unit.
[0008] In one possible design, the portion of the feed plate near the gyratory roller bends toward both sides of the gyratory roller, and the bent portion of the feed plate is fitted with a hanging rod for fixing the screen. The two ends of the screen are hung on the hanging rod, and the main body of the screen is covered by the lower part of the gyratory roller.
[0009] In one possible design, the surface portion of the oscillating roller covered by the screen accounts for more than 3 / 4 of its total surface.
[0010] In one possible design, the hanging rod is a split structure that can be detachably fixed inside the pelleting chamber.
[0011] In one possible design, the cross-sectional area of the feed channel gradually decreases towards the lower part.
[0012] In one possible design, the extruded column comprises a prism.
[0013] In one possible design, multiple connecting pieces are included, with the connecting pieces on both sides fixedly connected to the shaft of the motor, and the connecting piece in the middle being axially connected and fixed by the extrusion column.

[0015] Compared with the prior art, the present invention has at least the following advantages:
[0016] In this embodiment, material is fed into the granulation unit and guided by the feed channel formed by the feed plates into the oscillating roller. No screen is installed on the upper part of the oscillating roller, allowing large pieces of material to pass through the gaps in the extrusion columns. A screen is installed at the bottom of the oscillating roller, preventing large pieces from passing through. The motor is turned on, causing the oscillating roller to rotate continuously clockwise and counterclockwise. This means the extrusion columns move continuously relative to the screen. During rotation, the extrusion columns and the bottom screen shear, crush, and break down the material, resulting in fine particles that pass through the screen and are collected in the granulation unit. This oscillating roller granulation method can produce granules with high strength. Attached Figure Description

[0027] like Figure 1 and Figure 4As shown, this embodiment of the present invention provides a granule preparation device, including a granulation unit and a granulation collection unit 3;
[0028] The pelleting unit includes multiple feed plates 1 installed in the pelleting hopper. The multiple feed plates 1 and the inner wall of the pelleting hopper form a feed channel. A swing roller 2 is installed at the bottom of the feed channel. The swing roller 2 is driven to rotate by a motor. The swing roller 2 includes a connecting plate 21 and an extrusion column 22. Multiple extrusion columns 22 are fixedly connected to the connecting plate 21 circumferentially. The connecting plate 21 is fixedly connected to the rotating shaft of the motor. The bottom of the swing roller 2 is covered with a screen 4.
[0029] The pellet collecting unit 3 is funnel-shaped with an open top and is installed below the pelletizing unit to receive the pellets produced by the oscillating roller 2 in the pelletizing unit.
[0030] In this embodiment, the material is fed into the granulation unit and guided by the feeding channel formed by the feeding plate 1 into the oscillating roller 2. No screen 4 is installed on the upper part of the oscillating roller 2, allowing large pieces of material to enter through the gaps in the extrusion column 22. A screen 4 is installed at the bottom of the oscillating roller 2, preventing large pieces from passing through. The motor is turned on, causing the oscillating roller 2 to continuously oscillate and rotate clockwise and counterclockwise. This causes the extrusion column 22 to move continuously relative to the screen 4. During rotation, the extrusion column 22 and the bottom screen 4 shear, crush, and break the material, resulting in fine particles that pass through the screen 4 and are collected in the granulation unit 3. The rotational granulation method using the oscillating roller 2 can produce granules with high strength.
[0031] It should be noted that, in addition to the device provided in this application being able to increase the strength of the particles, adjusting the formulation of the granules can also increase the strength of the particles, for example, by increasing the moisture content of the material.
[0032] This formula, through the precise proportions of its components, enhances the binding strength of wet granular powder, laying the foundation for the preparation of high-strength granules.
[0033] In some embodiments of the present invention, the portion of the feed plate 1 near the swing roller 2 is bent toward both sides of the swing roller 2, and the bent portion of the feed plate 1 is equipped with a hanging rod 5 for fixing the screen 4. The two ends of the screen 4 are hung on the hanging rod 5, and the main body of the screen 4 is covered by the lower part of the swing roller 2.
[0034] In some embodiments of the present invention, the surface portion of the swing roller 2 covered by the screen 4 accounts for more than 3 / 4 of its total surface.
[0035] In this embodiment, the increased coverage angle of the screen 4 increases the force-bearing area of the particles, thus improving the yield. The increased coverage angle of the screen 4 increases the contact area and contact time between the material and the screen 4. This means that within the same granulation time, more material has the opportunity to contact the screen 4 and be screened, thereby increasing the screening output per unit time and contributing to the overall production efficiency of the granulator. A larger coverage angle of the screen 4 allows the material's movement trajectory within the granulator to better conform to the surface of the screen 4, enabling the material to more fully tumble and slide on the screen 4, reducing the likelihood of material re-adhesion or insufficient screening before discharge. Appropriately increasing the coverage angle of the screen 4 makes the compressive and shear forces experienced by the material during the granulation process more uniform. When the material contacts the screen 4, it can pass through the screen holes more smoothly, avoiding particle breakage caused by excessive localized force.
[0036] In some embodiments of the present invention, the hanging rod 5 is a split structure that can be detachably fixed inside the granulation chamber. This split, detachable design facilitates quick replacement of the screen 4 when needed, saving time and improving equipment efficiency.
[0037] In some embodiments of the present invention, the cross-sectional area of the feed channel gradually decreases towards the lower part. This arrangement facilitates material collection.
[0038] In some embodiments of the invention, the extrusion column 22 comprises a prism. The prism can be a triangular prism, a square prism, or a pentagonal prism. The prism's angular structure is more conducive to its crushing of materials.
[0039] In some embodiments of the present invention, a plurality of connecting pieces 21 are included. The connecting pieces 21 on both sides are fixedly connected to the rotating shaft of the motor, and the connecting piece 21 in the middle is axially connected and fixed by an extrusion column 22. The arrangement of a plurality of connecting pieces 21 inside the extrusion column 22 can improve the stability of the oscillating roller 2 and increase its radial strength.
[0040] In some embodiments of the present invention, the screen 4 is made of nylon. Nylon has high flexibility. Compared with metal screens 4, it is less prone to breakage or damage when subjected to material impact and friction, thus maintaining better integrity, extending service life, and reducing equipment maintenance costs.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
