Description

Technical Field

[0001] The utility model belongs to the field of granulators and relates to a high-speed granulator structure. Background Art

[0002] In modern industrial production, granulation technology is a widely used material processing process, which can process powdered or fine granular raw materials into particles of a certain shape and size, thereby improving the fluidity and processability of the material, and improving the stability and performance of the product. This technology is widely used in many industries such as pharmaceuticals, food, chemicals, fertilizers, etc. For example, in the pharmaceutical industry, granulation can ensure the uniform distribution of drug ingredients and make it easier to fill tablets or capsules; in the food industry, granulation helps to improve the taste and appearance quality of the product.

[0003] Traditional granulation methods usually involve mixing raw material powder with an appropriate binder and then pressurizing it, and then dividing the formed material into particles of the desired size by cutting or other physical means. Among them, the most common granulation equipment is the extrusion granulator, which works mainly by extruding the compressed raw material through a small hole in the mold and then using a cutter to cut it into particles. However, this traditional granulation method has some obvious limitations. First, since the material needs to be compressed before cutting, the efficiency of the entire process is relatively low. Second, since the particles are formed by cutting, they are often not strong enough and are easily broken during subsequent processing, resulting in a large number of incomplete particles in the final product, affecting product quality. Utility Model Content

[0004] The utility model aims to provide a high-speed granulator structure, which manufactures granules completely by extrusion molding, has a fast granulation speed, high granule integrity and good granule product quality.

[0005] In order to solve the above technical problems, the utility model provides a high-speed granulator structure, including a cylindrical shell, a rotating shaft is rotatably connected to the middle part of the shell, and the rotating shaft is driven to rotate by a driving motor. A circle of retaining ring is arranged on the bottom of the shell on the outer circumference of the rotating shaft, and an annular rolling area is formed between the retaining ring and the inner wall of the shell at the bottom of the shell, and a plurality of discharge ports distributed in a circle are opened at the lower part of the outer wall of the shell, and two connecting shafts distributed in a circle are arranged horizontally outwardly on the rotating shaft, one of which is rotatably connected to a rolling roller moving in the annular rolling area, and a gap is left between the rolling roller and the annular rolling area, and the other connecting shaft is rotatably connected to a pelletizing roller moving in the annular rolling area, and a plurality of closely distributed pelletizing holes are opened on the outer circumference of the pelletizing roller, and a connecting strip distributed in a circle with the two connecting shafts is arranged horizontally outwardly on the rotating shaft, and a scraper matching the annular rolling area is arranged downward on the connecting strip, and the lower side of the scraper contacts the upper surface of the annular rolling area.

[0006] By adopting the above technical scheme, when the driving motor drives the rotating shaft to rotate, the powder is sprinkled on the annular rolling area between the pelletizing roller and the scraper. After the rotating shaft drives the rolling roller to roll over the powder, the powder is compacted into a thin pancake. Then the pelletizing roller presses over the thin pancake and cuts the thin pancake into distinct particles through the pelletizing holes. The particles in the pelletizing holes are squeezed out through the silicone extrusion protrusions. Finally, the scraper rotates to scrape up the particles and finally throws the particles out from the discharge port.

[0007] The utility model is further configured that an annular material discharge net is provided on the top of the shell above the annular rolling zone, a material blocking plate is provided on the rotating shaft below the annular material discharge net, and a material discharge port is provided on the material blocking plate between the pelletizing roller and the scraper.

[0008] By adopting the above technical solution, through the cooperation of the material blocking plate and the annular material discharge net, the powder can always be evenly sprinkled on the annular rolling area between the pelletizing roller and the scraper.

[0009] The utility model is further configured that a transmission shaft is arranged on the upper end of the rotating shaft extending upwardly from the housing.

[0010] The utility model is further configured that an elastic silicone layer is arranged on the inner side of the pelletizing roller, and the elastic silicone layer extends into each pelletizing hole and is provided with a silicone extrusion protrusion.

[0011] By adopting the above technical solution, the silicone extrusion protrusion has elasticity, and after the pelletizing roller leaves the annular rolling zone, the silicone extrusion protrusion can automatically squeeze out the pellets in the pelletizing hole.

[0012] The utility model is further configured such that the lower side of the scraper blade is inclined toward the pelletizing roller, and the inner end of the lower side of the scraper blade is inclined toward the pelletizing roller.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Firstly, the utility model adopts a high-speed rotating shaft to drive the rolling roller, the granulating roller and the scraper to work simultaneously, and quickly performs cake pressing, granulation and granulation in sequence, so as to efficiently and quickly complete the powder granulation, and the granulation speed is fast;

[0015] Secondly, the utility model adopts cake pressing, pellet pressing combined with granulation, and manufactures granules completely by extrusion molding. The produced granules have high integrity, are not easy to break, and have good granule product quality. BRIEF DESCRIPTION OF THE DRAWINGS
