[0031] Combination Figures 1 to 5As shown, the utility model provides a wet granulator with uniform feeding, which includes a shell 1, a feeding belt 2 and a sprayer 3.

[0032] Combination Figures 1 to 5 As shown, a feed port 11 is opened on the side wall of the shell 1; the feed belt 2 is assembled in the feed port 11, and the two ends of the feed belt 2 are respectively located on both sides of the feed port 11; the sprayer 3 is assembled inside the shell 1, and the sprayer 3 is located directly above the feed belt 2; the raw material passes through the feed port 11 through the feed belt 2, and then the raw material is sprayed with a wetting agent through the sprayer 3 and finally falls into the shell 1.

[0033] In the process of conveying the drug raw material by the feed belt 2 in this embodiment, the wetting agent is mixed into the drug raw material by using the sprayer 3, so that the drug raw material and the wetting agent are preliminarily and evenly mixed before the mixer, the composition of the granulation raw material is more uniform before stirring, the required stirring time is reduced, and the granulation efficiency is improved.

[0034] In some embodiments, in combination Figure 3 As shown, a feed hopper 12 is integrally formed on the outer side wall of the shell 1, and the outlet of the feed hopper 12 is connected to the inside of the shell 1 through the feed port 11. The feed hopper 12 can concentrate the drug raw materials onto the feed belt 2, making it convenient for the drug raw materials to enter the shell 1.

[0035] In some embodiments, in combination Figure 2 , Figure 3 As shown, the feed ports 11 are evenly opened around the side wall of the shell 1, and each feed port 11 is equipped with a corresponding feed belt 2. Multiple feed ports 11 are opened on the shell 1 in a surrounding manner to perform feeding work, thereby improving the feeding speed.

[0036] In some embodiments, in combination Figure 4 As shown, the sprinkler 3 includes a nozzle 31, a water pipe 32 and a water inlet pipe 33. The nozzle 31 is connected to the water pipe 32. The water pipe 32 is annular. The nozzles 31 are evenly distributed along the water pipe 32. The water inlet pipe 33 is connected to the water pipe 32. The water inlet pipe 33 passes through the top plate of the shell 1. All the nozzles 31 are connected by the water pipe 32, which ensures the synchronization of the spraying action of the nozzle 31 and is conducive to controlling the spraying amount.

[0037] In some embodiments, in combination Figure 4 As shown, the water inlet pipes 33 are evenly distributed along the water pipe 32. Using multiple water inlet pipes 33 has a stronger supply capacity. The evenly distributed water inlet pipes 33 are conducive to ensuring the balance of internal pressure at various locations in the water pipe 32 and ensuring the uniformity of the spraying effect.

[0038] In some embodiments, in combination Figures 1 to 5 As shown, the shell 1 also includes a discharge port 13, which is integrally formed on the bottom plate of the shell 1. The mixed raw materials passing through the discharge port 13 will be granulated. The discharge port 13 located on the bottom plate of the shell 1 is conducive to the discharge of the mixed raw materials.

[0039] In some embodiments, in combination Figure 5 As shown, the bottom plate of the shell 1 is funnel-shaped, the funnel-shaped inlet of the bottom plate is connected to the side wall of the shell 1, and the funnel-shaped outlet of the bottom plate is connected to the discharge port 13. The funnel-shaped bottom plate can play a guiding role, which is beneficial for sending the mixed raw materials to the next process and avoiding affecting the stirring of the next batch of raw materials due to residual problems.

[0040] In some embodiments, in combination Figure 1 , Figure 5 As shown, the wet granulator with uniform feeding also includes a stirrer 4, and the stirrer 4 includes a stirring rod 41. The stirring rod 41 is assembled inside the shell 1. The vertical height of the stirring section of the stirring rod 41 is lower than the feeding belt 2. The stirrer 4 will stir the mixed raw materials again to improve the uniformity of the raw materials. Only the part of the stirring rod 41 below the feeding belt 2 will contact the raw materials, so the height of the stirring rod 41 is limited to avoid waste.

[0041] In some embodiments, in combination Figure 5 As shown, the mixer 4 also includes a driving motor 42, which is fixedly connected to the top plate of the shell 1, and the driving end of the driving motor 42 passes through the top plate to connect to the stirring rod 41, and the driving motor 42 drives the stirring rod 41 to rotate.

[0042] In some embodiments, in combination Figures 1 to 5 As shown, the feed belt 2 is a conveyor belt, the bottom surface of the feed belt 2 is in contact with the bottom surface of the feed port 11, and a gap is left between the top surface of the feed belt 2 and the top surface of the feed port 11. The feed belt 2 realizes uniform and controllable addition of raw materials. The bottom surface is fitted to remove excess items, and the gap on the top surface limits the thickness of the raw materials on the feed belt 2. The lower the thickness of the raw materials on the feed belt 2, the more complete and uniform the mixing of the wetting agent is.

[0043] Working process: The drug raw material is transferred along the feed belt 2 through the feed port 11 to the inside of the shell 1. During this process, the sprayer 3 sprays the wetting agent onto the drug raw material to achieve preliminary mixing of the drug raw material and the wetting agent. The mixed raw material finally falls into the shell 1.

[0044] The raw materials entering the mixer 4 are more uniform, and the mixer 4 will stir the mixed raw materials to make the ingredients more uniform, thereby achieving efficient granulation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
