Technical Field
[0001] This utility model relates to the field of calcium carbonate granulation technology, and in particular to a granulation device for producing calcium carbonate masterbatch. Background Technology
[0002] Calcium carbonate is an inorganic compound, appearing as a white crystalline powder, tasteless and odorless. It is widely found in nature, serving as a major component of materials such as limestone, marble, and seashells. As an important industrial raw material, calcium carbonate is used in the construction industry to produce cement and lime. In the rubber and plastics industries, it is often used as a filler to improve material properties. Calcium carbonate is also closely related to life activities, being an important component of animal bones and teeth. Furthermore, it has applications in the medical field, such as serving as a calcium supplement to help the body replenish calcium and treating hyperacidity by reacting with stomach acid to relieve discomfort. In addition, calcium carbonate is often used in laboratories as a raw material for the preparation of carbon dioxide gas.
[0003] The production of calcium carbonate masterbatch involves mixing calcium carbonate powder with carrier resin, dispersants, and other additives through a specific process to produce granular products. First, the calcium carbonate undergoes surface treatment, and coupling agents and other additives are used to improve its compatibility with the resin. Then, it is mixed with polyethylene and polypropylene carrier resins, lubricants, and antioxidants in a specific ratio. After high-speed stirring and pre-dispersion, the mixture is melt-blended at high temperature using a twin-screw extruder, ensuring that the calcium carbonate is uniformly dispersed in the resin matrix. However, the lack of a stable granulation device during production can negatively impact the performance. With advancements in technology… Progressive granulation equipment is a key device for processing melt-blended materials into granules. Its core consists of an extrusion system, a pelletizing system, and a cooling system working together. The extrusion system usually uses a twin-screw extruder. Through the rotation, conveying, and shearing action of the screws, calcium carbonate and resin melt are fully mixed and extruded from the die head as a uniform melt flow. The die head is mostly a plate or steel frame structure, and the shape and size of the discharge port can be adjusted according to needs. However, this type of granulation mechanism cannot screen out particles of different sizes after granulation, resulting in inconsistent sizes, which in turn affects the subsequent use effect.

[0022] Working principle: First, raw materials are added through the feed inlet 9, accumulating inside the square box 501. Then, cylinder 401 is activated, pushing the extrusion block 402 to extrude along the inner wall of the square box 501. The raw materials then enter the extrusion disc 304 through the connecting pipe 502 and are extruded through the holes in the extrusion disc 304. At this point, motor 3061 is activated, driving the rotating rod 3062 to rotate. The rotating rod 3062 then drives the cutting blade 3063 to cut along the outer wall of the extrusion disc 304, cutting the raw materials into granules. On the filter disc 601, the motor 201 is started. The motor 201 will drive the rotating rod 202 to rotate, and the rotating rod 202 will drive the gear 203 to rotate. Then the gear 203 will drive the gear 204 to rotate, and the gear 204 will drive the eccentric wheel 205 to rotate. At the same time, the rotating rod 206 will rotate along the inner wall of the eccentric wheel 205, and at the same time drive the rotating plate 2071 and the push block 2072 to vibrate the filter disc 601. At this time, large particles will remain in the filter disc 601, and small particles will fall down, realizing the function of automatically screening particles and ensuring that the particle size is consistent. When the holes on the extrusion disc 304 are clogged and need repair or replacement, first rotate the cylindrical sleeve 303. At this time, the cylindrical sleeve 303 will drive the external thread 302 to rotate along the outer wall of the threaded sleeve 301 and move away from the threaded sleeve 301. Then unscrew the bolt 305, and the bolt 305 will move away from the extrusion disc 304 and the cylindrical sleeve 303, so that the extrusion disc 304 can be replaced. This achieves the function of quickly replacing the damaged and clogged extrusion disc 304.
