Description

Technical Field

[0001] This utility model relates to the field of air-cooled granulator technology, and in particular to an air-cooled granulator. Background Technology

[0002] An air-cooled granulator is a device used to cool and solidify molten materials, then cut them into granules. It is widely used in chemical, plastics, water treatment, and environmental protection materials industries. Its core principle is to rapidly cool high-temperature molten materials using forced air cooling technology, causing them to solidify and then mechanically cut into uniform granules. Traditional granulators often use water cooling, but water cooling suffers from high water consumption and complex subsequent drying processes. In contrast, air-cooled granulators achieve cooling through air convection, offering advantages such as energy saving, environmental friendliness, ease of operation, and stable granule quality, gradually becoming the mainstream choice in the industry.

[0003] Despite technological advancements in air-cooled granulators, existing equipment still suffers from the following shortcomings:

[0004] Traditional air-cooling systems often use unidirectional airflow, resulting in uneven cooling. This makes the particle surface prone to thermal stress cracks, and the lack of real-time temperature monitoring and feedback mechanisms makes it difficult to dynamically adjust the cooling intensity, thus affecting the particle molding quality.

[0044] Working principle:

[0045] Raw material processing stage: The material is fed into the feed frame 16, compacted by the lower pressure plate 18, and then enters the twin-screw extruder 15. The electromagnetic heater 22 heats and plasticizes the material, and the water cooling box 23 cools the end to ensure that the melt viscosity is appropriate.

[0046] Extrusion and granulation stage: The plasticized melt is extruded into strips through the granulation head 14, and the cutter 13 rotates at high speed under the drive of the servo motor 11 to cut the strip material into granules.

[0047] Air cooling and discharge stage: The first nozzle 51 of the air cooling mechanism 5 sprays cold air into the sealing cover 3, and the second nozzle 52 cools the inside of the discharge pipe 4. The particles solidify rapidly under dual cooling. The exhaust fan 62 of the ventilation mechanism 6 exhausts the hot and humid air.

[0048] Temperature monitoring and regulation: Temperature sensor 7 monitors the internal temperature of granulation box 2 in real time. If the temperature exceeds the limit, the air volume is increased through the first solenoid valve 55 and the second solenoid valve 56 to ensure the cooling process is stable.

[0049] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
