[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figure 1As shown, the utility model provides a solid preparation granulator, including a supporting device, a granulator and a material receiving device; wherein the supporting device includes a top plate 1, a supporting column 2 and a base 3, and the base 3 and the top plate 1 are supported and connected by the supporting column 2.
[0027] The granulation device includes a granulation barrel 4, a feed trough 13, a drive motor 12, a rotating shaft 8, a granulation knife 9 and a scraper device; the granulation barrel 4 is vertically fixed at the lower end of the top plate 1 and is located directly above the storage barrel 5, the lower end of the granulation barrel 4 is connected to the upper end of the storage barrel 5, and the upper end of the granulation barrel 4 is provided with a feed trough 13; the drive motor 12 is fixedly arranged on the top plate 1, the output shaft of the drive motor 12 is fixedly connected to the upper end of the rotating shaft 8, the granulation knife 9 is fixedly arranged on the rotating shaft 8, the end of the rotating shaft 8 extends downward to the bottom of the granulation barrel 4, the drive motor 12 drives the rotating shaft 8 to rotate, and then drives the granulation knife 9 to rotate in the granulation barrel 4; the rotation speed of the drive motor 12 directly affects the rate of material crushing, and the granulation efficiency can be improved by increasing the rotation speed of the drive motor 12, and the rotation speed of the drive motor 12 can be manually set according to actual needs.
[0028] During the operation of the granulator, the granulated material is easy to stick to the inner wall of the granulator barrel 4, and this part of the material cannot enter the next link of the production process, resulting in waste; on the other hand, the inner wall of the granulator barrel is easy to form dirt over time, and the granulator barrel generally needs to be disassembled to completely clean the material on the inner wall, which seriously increases the time cost and labor cost of production and reduces the granulation efficiency of the machine. In order to solve the above problems, the granulator device of this embodiment is also provided with a scraper device, such as Figure 1 and Figure 2 As shown, the scraper device includes a connecting rod 10 and a scraper knife 11. The connecting rod 10 is vertically fixed on the rotating shaft 8. The rotating shaft 8 and the connecting rod 10 are fixedly connected by a coupling. In this embodiment, four connecting rods 10 and four scraper knives 11 are included. Each scraper knife 11 is respectively connected to a corresponding connecting rod 10. The length of the connecting rod 10 is set so that the outer side surface of the scraper knife 11 connected thereto is just in close contact with the inner wall of the whole grain barrel 4. Multiple scraper devices are respectively arranged in sequence along the extension direction of the rotating shaft and are evenly distributed in the axial direction of the rotating shaft.
[0029] like Figure 3As shown, the scraper 11 is an arc-shaped blade, and a blade is provided at one end of the scraper 11 close to the rotation direction; the inner side of the scraper 11 is an arc-shaped surface, and the outer side matches the shape of the inner wall of the whole grain tube 4, so that the outer side of the scraper 11 can fit tightly on the inner wall of the whole grain tube 4. When the driving motor 12 is running, driven by the rotating shaft 8, the outer side of the scraper 11 is close to the inner wall of the whole grain tube 4, rotates along the inner wall of the whole grain tube 4, and scrapes off the materials adhering to the inner wall in time, reducing the labor cost and time cost caused by disassembly and cleaning, and extending the service life of the equipment; at the same time, the movement of the scraper generates a strong shear force, and the material forms a kneading force in the process of strong impact and continuous turning, so that the materials with different flow rates above the scraper diffuse with each other, so that the materials are fully granulated in the whole grain tube 4, and the materials are timely prevented from adhering to the inner wall of the whole grain tube 4, reducing material waste, achieving the effect of full dispersion and crushing, and greatly improving production efficiency.
[0030] like Figure 2 and Figure 3 As shown, the width of the scraper blade 11 gradually increases from one end to the other, and the narrow end is connected to the connecting rod 10. This structure is beneficial to reducing the resistance at the connection position between the scraper blade 11 and the connecting rod 10, and can effectively avoid the connection between the scraper blade 11 and the connecting rod 10 being suddenly disconnected during the high-speed operation of the scraper blade 11.
[0031] like Figure 1 As shown, the material receiving device includes a storage barrel 5 and a filter screen 7; the storage barrel 5 is in an inverted cone shape, and a discharge port 6 is provided at the lower end, which is conducive to the centralized collection of the whole-granulated materials. The upper end of the storage barrel 5 is connected to the lower end of the whole-granulated barrel 4, and the upper end of the storage barrel 5 and the lower end of the whole-granulated barrel 4 are both opened. A filter screen 7 is provided between the storage barrel 5 and the whole-granulated barrel 4. The filter screen 7 is as shown in FIG. Figure 4 As shown, by setting the filter screen 7, the granulated material can be directly dropped into the storage barrel 5, while preventing the incompletely crushed material from entering the storage barrel 5. The mesh number of the filter screen 7 can be manually set according to the granulation standard.
[0032] The working principle of the utility model is as follows: the material enters the granulating barrel through the feeding trough, the driving motor drives the rotating shaft connected thereto to rotate, the rotating shaft drives the granulating knife and the scraper knife arranged thereon to rotate at high speed, the granulating knife directly crushes the material, the scraper knife scrapes off the material attached to the inner wall of the granulating barrel during the granulating process, and at the same time blocks and scatters the material that is about to adhere to the inner wall due to the force generated by the granulating knife, the scattered material enters the action range of the granulating knife to continue granulating, and finally realizes efficient granulation of the material; the material after granulation is filtered through the filter screen between the granulating barrel and the storage barrel, and enters the storage barrel, and the solid preparation that is not completely crushed remains in the granulating barrel to continue granulating; the material in the storage barrel is collected through the discharge port at the lower end of the storage barrel.
[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
