[0002] A granulator is a common type of granulation equipment, widely used in a variety of fields, including chemical, pharmaceutical, food, and agriculture. Its core function is to transform liquid raw materials into granules of varying shapes, sizes, and densities through a specific process. This conversion not only improves raw material utilization but also facilitates subsequent storage, transportation, and application.

[0003] Existing granulators often utilize an external rotary mechanism, with the rotating shaft exposed. This makes operators vulnerable to entanglement or crushing, posing a significant safety risk. This technology also places high demands on mechanical stability. The exposed components are also more susceptible to external influences such as dust and temperature fluctuations, impacting product quality and production reliability. Furthermore, devices with external rotary mechanisms are often complex in structure, resulting in high maintenance and production costs. Summary of the Invention

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0027] First, combine Figures 1 and 2 The internal rotating scraper granulator according to the embodiment of the present invention is described, which is used to produce granular products of molten materials and has a wide range of application scenarios.

[0028] like Figures 1 and 2As shown, the internal rotating scraper granulator of the embodiment of the present invention includes: a heat preservation mechanism 1, an internal rotating mechanism and a feeding pipe 3.

[0029] Specifically, if Figures 1 and 2 As shown, in this embodiment, a dripping hole 11 is provided at the bottom of the insulation mechanism 1; an inward rotating mechanism is rotatably disposed within the insulation mechanism 1; and a feed pipe 3 is disposed at the top of the insulation mechanism 1 to facilitate smoother material delivery to the inward rotating mechanism. The feed pipe 3 passes through the insulation mechanism 1 and connects the inward rotating mechanism. The feed pipe 3 feeds molten material between the insulation mechanism 1 and the inward rotating mechanism, whereupon the inward rotating mechanism rotates and drives the molten material to the dripping hole 11 for delivery. The dripping hole 11 protrudes from the insulation mechanism 1. In this embodiment, the insulation mechanism 1 ensures that the material remains molten and does not solidify. The outwardly convex dripping hole 11 effectively guides the molten material to drip from the insulation mechanism 1. Because the hole is convex, it effectively acts as a material flow guide, helping the material maintain a certain speed and direction during dripping, reducing the possibility of molten material directly accumulating at the bottom of the insulation mechanism 1 and reducing contamination of the outer wall of the insulation mechanism 1. Multiple dripping holes 11 may be provided, or multiple rows of them may be provided. Their size, number, and arrangement can be adjusted according to actual usage requirements.

[0030] Further, if Figures 1 and 2 As shown, in this embodiment, the heat-insulating mechanism 1 comprises an inner sleeve 12, which is mounted on the inner rotating mechanism; an outer sleeve 13, with both ends of the outer sleeve 13 connected to the inner sleeve 12. A hollow cavity 14 is formed between the outer sleeve 13 and the inner sleeve 12, and the hollow cavity 14 is filled with a first heat-insulating medium. The hollow cavity 14 and the first heat-insulating medium effectively isolate the inner rotating mechanism from the external environment, reducing heat loss and keeping the material in a molten state.

[0031] Further, if Figures 1 and 2 As shown, in this embodiment, a medium input port 15 and a medium output port 16 are provided on the shell 13. The medium input port 15 is used to input the first thermal insulation medium into the hollow cavity 14, and the medium output port 16 is used to output the discarded first thermal insulation medium, so as to facilitate the updating and replacement of the first thermal insulation medium.

[0032] Further, if Figures 1 and 2 As shown, in this embodiment, the feed pipe 3 has a hollow jacket structure. The inner and outer walls of the feed pipe 3 are filled with a second insulation medium to ensure that the material remains in a molten state after being input through the feed pipe 3. The first insulation medium and the second insulation medium can be the same or different. If the first insulation medium and the second insulation medium are the same, the feed pipe 3 and the insulation mechanism 1 can be integrally formed and manufactured.

[0033] Further, if Figures 1 and 2As shown, in this embodiment, the internal rotation mechanism includes: a rotating shaft 21, which is disposed within and extends through the heat-insulating mechanism 1; a driving member 22, which is connected to one end of the rotating shaft 21 and drives the rotating shaft 21 to rotate; and a plurality of scrapers 23, which are disposed between the rotating shaft 21 and the heat-insulating mechanism 1 and fixed to the rotating shaft 21. The scrapers 23 are evenly spaced around the rotating shaft 21, with their lengths parallel to the length of the rotating shaft 21. Gaps 24 are provided between adjacent scrapers 23, into which molten material is fed from the feed pipe 3. As the driving member 22 drives the rotating shaft 21 to rotate, the gaps 24 connect to the dripping holes 11, causing the material to drip out. For thick materials, the scrapers 23 can effectively scrape and push the material during rotation. The scrapers 23 can also shear the material at the dripping holes 11, facilitating its dripping and forming. The driving member 22 may be a speed-regulating motor to adjust the rotation speed of the rotating shaft 21 .

[0034] Further, if Figures 1 and 2 As shown, in this embodiment, the thickness of the scraper 23 is not less than the diameter of the dripping hole 11. When the scraper 23 moves to the dripping hole 11, the hole is closed, thereby achieving intermittent and continuous dripping of the material.

[0035] Further, if Figures 1 and 2 As shown, in this embodiment, the scraper 23 is fixed to the rotating shaft 21 by screws 25, which is convenient for disassembly, installation and replacement.

[0036] Further, if Figures 1 and 2 As shown, in this embodiment, mechanical seals 4 are installed at both ends of the rotating shaft 21. The mechanical seals 4 are arranged between the rotating shaft 21 and the heat preservation mechanism 1 to prevent the leakage of molten material and the entry of external pollutants.

[0037] Further, if Figures 1 and 2 As shown, in this embodiment, bearing seats 5 are installed at both ends of the rotating shaft 21, bearings are installed in the bearing seats 5, and the bearing sleeves are arranged on the rotating shaft 21 to achieve effective support for the rotating shaft 21.

[0038] During operation, molten material is first fed into the feed pipe 3. It then drips through the gap 24 and into the corresponding dripping hole 11, where it is then output to the external cooler 6. With each rotation of the rotating shaft 21, a certain amount of molten material drips through the dripping hole 11. After the scraper 23 reaches the dripping hole 11, the hole closes, thus achieving both intermittent and continuous dripping of the material.

[0039] Above, refer to Figures 1 and 2The invention describes an internal rotating scraper granulator according to an embodiment of the invention. The rotation process is completely carried out inside the machine, the operation is safer and more reliable, the safety hazards caused by exposed rotating parts are effectively avoided, the machine is not easily affected by external factors, and the product quality and production reliability are improved.
