Product Description
Introducing the state-of-the-art S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd. This extraordinary innovation stands as a beacon in the realm of sand grain rejuvenation. Utilizing a formidable double-axis mechanism, it skillfully eradicates the resin curing agent that clings to the surface of sand grains. Employing dynamic rubbing and advanced de-filming processes, it transforms sand grain cleanliness and integrity with unparalleled precision.
Boasting superior efficiency, the machine's base is equipped with a high-performance fan that meticulously separates stubborn old film and dust, ensuring an immaculate finish. The rejuvenated old sand emerges with remarkable integrity and perfectly rounded grains, presenting a significantly enhanced quality. This upgrade drastically reduces the need for additional liquid materials in subsequent mixing processes, offering a more cost-effective and highly efficient solution. Discover the future of sand recycling with the revolutionary S53 Scrubber Recycling Machine, where innovation meets practicality.
As the pivotal equipment for the regeneration of foundry old sand, the robust rubbing regeneration machine achieves efficient stripping and renewal of old sand types, like resin sand and water glass sand. It achieves this through the harmonious combination of dual-axis mechanical rubbing and airflow assistance. Below is a comprehensive analysis covering technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The innovative dual-axis regeneration machine employs two sets of transmission main shafts rotating in opposing directions at high speed (ranging from 720-970r/min). On these shafts, wear-resistant alloy blades or cast iron rubbing discs are installed. Once the sand enters the regeneration chamber, it is subjected to repeated rubbing and collision under the linear shear force and convection of these blades. This mechanical prowess not only removes the resin film and curing agent from the sand's surface but also achieves surface rounding through friction among sand particles, minimizing edge damage. In comparison to the traditional three-axis structure, the dual-axis design optimizes chamber space, elevates material throughput by 10-30t/h, and reduces energy consumption effectively.
2. Boiling airflow assists film stripping. A bottom blower with an air volume exceeding 3700m³/h injects adjustable airflow into the chamber through the boiling orifice plate, creating a fluidized blend of sand and air. This mechanism amplifies collision frequency among sand particles and simultaneously evacuates detached inert film and dust through the dust removal vent. This synergistic 'mechanical + airflow' effect raises the film stripping rate to over 80%, while also reducing sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. Utilizing the carbide convex rib welding process, the rubbing blade's wear resistance is enhanced by more than triple; the chamber body and frame are elastically connected with rubber, effectively suppressing vibrations from high-speed operations and ensuring equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: Through 180 seconds of rigorous rubbing, the brittle resin film is effectively removed. The burning loss is kept below 1.0%, and the tensile strength of the regenerated sand is restored to 90% of the new sand.
Water glass sand: Requires combination with wet regeneration (sand-water ratio 1:1.5) or a low-temperature freezing centrifugal process (-40ºC). Meanwhile, dry regeneration as a pretreatment can effectively reduce the subsequent wet load.
Alkali phenolic resin sand: The robust film demands higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of the sand particles is improved, and gas emissions are decreased by 30%.
5. Technical advantages and economy
The regeneration efficiency is significantly enhanced. In contrast to traditional centrifugal regeneration machines (power 22kW/stage) or air flow impact equipment, the unit energy consumption of the double-axis regeneration machine is cut by 40%. Furthermore, the sand particle crushing rate is maintained within 5%, and its integrity surpasses that achieved by vibration regeneration.
Unlock unparalleled production cost efficiency! With our innovative solutions, experience an impressive optimization of production costs. The resin active film residue present in the regenerated sand, maintained at a minimal level of less than 0.3%, empowers you to slash the curing agent usage by an incredible 30% to 50% during sand mixing. Witness a transformation in your sand usage with a revolutionary sand-iron ratio adjustment from 1:1 to an optimized 1:1.5, drastically curtailing the expenses associated with purchasing new sand.
