Description

Technical Field

[0001] This utility model relates to the technical field of fish oil processing equipment, specifically to an activated carbon feeding device for a fish oil decolorization kettle. Background Technology

[0002] In the production of fish oil, decolorization is a crucial step, aimed at removing pigments, odors, and other impurities to improve its quality and color. Activated carbon, with its highly developed pore structure and large specific surface area, possesses excellent adsorption capacity for pigments and impurities, making it a widely used adsorbent in fish oil decolorization processes.

[0003] However, existing methods for feeding activated carbon into fish oil decolorizing reactors have many shortcomings. Traditional feeding methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the accuracy and stability of the feeding amount, thus affecting the consistency of the decolorization effect. In addition, manual feeding easily generates activated carbon dust, which not only pollutes the working environment but also endangers the health of operators.

[0004] While some feeding systems employ mechanical conveying devices, they still fall short in terms of sealing and automation. Leaks during the conveying process not only waste activated carbon but also further exacerbate environmental pollution. Moreover, existing systems often lack real-time monitoring and feedback control of the activated carbon conveying process, making it difficult to promptly detect and resolve malfunctions such as blockages and material jams, thereby affecting the continuity and stability of production.

The volume of the powder is weighed by the weighing device 104 during the replenishment process. After charging is complete, the second pneumatic ball valve 1061 closes, and the fourth pneumatic ball valve 1091 of the exhaust pipe 109 opens. A vacuum is then applied to the activated carbon tank 1 using a vacuum pump or other vacuuming equipment. After vacuuming, the fourth pneumatic ball valve 1091 closes, and negative pressure material extraction begins.
