Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and more specifically, to a wet granulator. Background Technology

[0002] Wet granulation machines are commonly used in the pharmaceutical, chemical, and food industries. They are used to form granules from powdered materials by adding water or other liquid binders. Specifically, the dry powder material to be granulated is fed into the machine, and a liquid (usually water or binder solution) is evenly sprayed into the powder through a spraying device while stirring to promote the bonding between the materials. The mixed material is then stirred and collided to form wet granules of different sizes. The wet granules are then dried to remove excess moisture and achieve the desired granulation characteristics. For example, Chinese patent CN219899090U discloses a rapid wet granulation device, including a base frame, a granulator mounted on the base frame, and a collection component mounted on the base frame and located on one side of the granulator. The granulator's outlet is equipped with a screening component, which includes a U-shaped guide plate at the outlet. The U-shaped guide plate has several screening holes, and a dredging plate is located inside the U-shaped guide plate. Several dredging columns are located at the bottom of the dredging plate corresponding to the screening holes. The collection component includes a side plate located below the U-shaped guide plate and on one side of the base frame, with a collection box on the side plate. This technical solution can quickly separate and remove debris from the finished granules, and also facilitates cleaning of the screening components. However, during the wet granulation process, the resulting granules often exhibit uneven size and shape. To meet subsequent production needs, it is usually necessary to separate and collect the granules according to different size ranges. Simply separating the granules from the debris is often insufficient to meet subsequent production requirements. Utility Model Content

[0006] The screening assembly includes a guide plate disposed at the discharge port of the granulator. The guide plate has a plurality of screening holes. The end of the guide plate is connected to a plurality of separation channels for particle flow. The plurality of separation channels are arranged side by side and closely arranged along the width direction of the guide plate. A screening groove is formed on the bottom surface of the separation channel along the length direction. The width of the screening groove gradually increases along the particle flow direction.

[0007] The collection assembly includes multiple collection boxes, one of which is disposed below a screening trough, with the opening of the collection box facing the screening trough.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Example 1

[0023] A wet granulation machine includes a granulator 1, wherein a screening component is provided at the discharge port of the granulator 1, and a collection component is provided below the screening component.

[0024] The screening assembly includes a guide plate 2 disposed at the discharge port of the granulator 1. The guide plate 2 has a plurality of screening holes 21. The end of the guide plate 2 is connected to a plurality of separation channels 3 for particle flow. The plurality of separation channels 3 are arranged side by side and closely arranged along the width direction of the guide plate 2. The bottom surface of the separation channel 3 has a screening groove 31 for particle to fall into along the length direction. The width of the screening groove 31 gradually increases along the particle flow direction.

[0025] The collection assembly includes multiple collection boxes 4, one of which is located below a screening trough 31, and the opening of the collection box 4 is opposite to the screening trough 31. Multiple partitions 42 are provided inside the collection box 4, and the partitions 42 divide the interior of the collection box 4 into multiple collection chambers 41.

[0026] Working Principle: In use, the finished granules produced by the granulator 1 flow out along the guide plate 2 at the outlet. As the finished granules flow through the guide plate 2, any debris is sieved through the screening holes 21, causing it to fall into the waste collection box at the bottom for collection, thus initially separating impurities from the finished granules. The finished granules then continue flowing into the separation channel 3 at the end of the guide plate 2. Since the size and shape of the finished granules are often uneven, this invention separates granules of different sizes by creating a screening groove 31 along the length of the bottom surface of the separation channel 3. The width of the screening groove 31 gradually increases along the flow direction of the granules. This process allows the finished granules to pass through the screening channel. During the flow process within the separation channel 3, smaller particles fall from the narrower screening trough 31 at the front end, while larger particles continue to slide down the screening trough 31 until they reach a suitable position and fall out. This allows particles of different sizes to be separated step by step within the screening trough 31. The separated particles of different sizes then fall sequentially into the collection chamber 41 of the collection box 4 below, meaning that one collection chamber 41 can collect finished particles of a certain particle size range. In this way, after the particles are discharged, not only can the debris mixed in with the particles be separated, but finished particles of different sizes can also be separated and collected sequentially, greatly improving the screening effect of the finished particles after granulation and increasing the production efficiency of the enterprise.

[0027] In this embodiment, both the guide plate 2 and the separation channel 3 are inclined, and are inclined from high to low from the end near the outlet of the pellet mill 1 to the end away from the outlet of the pellet mill 1. This facilitates the faster downward conveying of the discharged particles along the guide plate 2 and the separation channel 3, and in this process, better screening of the finished particles is achieved.

[0028] In this embodiment, the two sides of the separation channel 3 have a certain height; that is, the left and right sides in the direction of finished product particle flow, so as to prevent finished product particles from splashing out of the separation channel 3 during the flow process.

[0029] In this embodiment, the opening range of the collection box 4 is not less than the orthographic projection of the screening trough 31, which can better ensure that the particles at the top can fall into the corresponding collection chamber 41 during the screening process, thereby improving the particle collection effect.

[0030] In this embodiment, the aperture of the sieve hole 21 is much smaller than the minimum diameter of the particle, ensuring that the particle will not fall to the bottom through the sieve hole 21.

[0031] In this embodiment, along the flow direction of the particles, the guide plate 2 is provided with a plurality of baffles 22. One of the baffles 22 is connected to the side of an adjacent separation channel 3. This can better ensure that the particles on the guide plate 2 enter each separation channel 3 in a more orderly manner, and avoid blockage at the bottom of the guide plate or in some separation channels 3, which would affect the screening effect of the particles.

[0032] In this embodiment, the width of the guide plate 2 gradually decreases from near the outlet of the pellet mill 1 to away from the outlet of the pellet mill 1. This allows it to receive more granular material near the outlet of the pellet mill 1 and then gradually gather the granular material downwards for better delivery to each separation channel 3.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
